Sheet 4 of 5 Patented Sept. 8, 1970 Sheet MEDICAL APPARATUS FOR TRANSPORTATION, TREATMENT AND HOSPITALIZATION OF POLYTRAUMATIZED PERSONS The present invention is concerned with a medical apparatus which is intended for the transportation, treatment and hospitalization of polytraumatized persons, persons suffering from burns and radiation injuries, patients who have undergone operations and sick persons suffering from serious ailments. This apparatus is designed to support the polytraumatized person from the time of causation of the injury to the time of recovery without any essential need to remove the patient from the enclosure in which he is resting in order to render all the medical assistance which his condition demands. In particular, the apparatus forms an orthopedic bed, X-ray table, operating table and hydrotherapy appliance.

A characteristic which is common to many fields of modern industry (the petrochemical industry, nuclear power stations, handling of propergols), to modern warfare techniques (nuclear armaments, rockets, napalm, phosphorus) and to road, rail or air accidents is the fact that they give rise to particular types of injuries resulting from the association in one person of pathological phenomena having different causes, as in persons suffering from fractures and burns, from fractures and blast injuries, wounds and burns, fractures and intoxications, wounds and radiation injuries, and so forth.

Under such circumstances, the effectiveness of surgical and reanimation techniques depends on their speed of application as well as on the quality of the first aid given at accident locations but above all on the number of handling operations and modes of transportation ofinjured persons.

In point of fact, the different types of equipment which exist at the present time are usually designed solely for the purpose of treating a single type of injury or for applying a single kind of reanimation, that is to say for simple and well-defined cases. In consequence, satisfactory treatment of complex injuries is made correspondingly more difficult as the types of equipment referred-to are incompatible with respect to each other and therefore necessitate a fairly large number of handling and carrying operations.

It follows from the foregoing, for example, that a road accident victim who has been thrown from his car and suffers from an open fracture of the thigh and abdominal contusions has to undergo between ten and fourteen manipulations and between five and seven carrying operations on a trolley before finally being laid in bed. Now it is well known that manipulations, low temperatures, noises and changes of position aggravate the condition of a polytraumatized patient to a marked degree.

Moreover, polytraumatized persons who have been exposed to radiation give rise to particularly serious and complex problems, taking into account their sensitivity to infection and the hazards to to which they themselves expose attending physicians and nursing staff. In point of fact, there is no equipment at present in existence which meets the requirements of this particular form of pathology.

The present invention provides a solution to these different problems, and is accordingly concerned with a general-purpose apparatus which provides the following main advantages:

1. Operations involving handling and transferring the patient on trolleys are almost completely dispensed with.

2. The most elaborate reanimation techniques can be applied simultaneously.

3. Technical means which are demanded by the particular state of the injured person can be brought to actual accident locations.

4. Patients can be transferred from an accident location to the hospital center or from one hospital to another under the best possible conditions without thereby incurring any risk of modification of temperature and without any interruption of the care and treatment being given at the time of transfer.

More specifically, the present invention is concerned with a medical apparatus which is intended for the transportation,

treatment and hospitalization of polytraumatized persons, per sons suffering from burns, radiation injuries, operated persons and patients suffering from serious injuries and ailments, which forms in particular an orthopedic bed, X-ray table, operating table, hydrotherapy appliance, and which permits both the positioning and turning of the patient, the said apparatus being characterized in that it comprises:

a fluid-tight box-mattress unit;

an enclosure which can be fitted around the periphery of said box-mattress unit;

a system of leak-tight attachment of said enclosure to the box-mattress unit;

means intended to supply said enclosure with liquids and gaseous mixtures;

a removable stretcher which is placed on the box-mattress unit inside the enclosure;

and lifting mechanisms intended to carry out different manipulations of said stretcher.

The stretcher is advantageously constituted by an articulated frame fitted with flexible and detachable crossbands, at least one end of which is rigid. Said stretcher can be associated with liftingsystems permitting of both angular positioning and longitudinal reversal thereof. In the case last mentioned, the stretcher is rigidly fixed to a second stretcher or so-called ventral stretcher.

Further properties and advantages of this invention will become apparent from the description which now follows in reference to the accompanying drawings and in which one form of construction of the apparatus is given by way of explanation but not in any limiting sense.

In these drawings:

FIG. 1 is a longitudinal sectional view of the apparatus according to the invention which is shown without its handling hood;

FIG. 2 is a transverse sectional view of the apparatus which is fitted with its handling hood;

FIG. 3 is a view in perspective ofthe main stretcher;

FIG. 4 is a sectional diagram of the mechanism for longitudinal reversal of the stretchers; and finally,

FIG. 5 is a top view of said mechanism.

From FIGS. 1 and 2, it is apparent that the apparatus according to the invention comprises a box-mattress whose frame 1 which is formed of light alloy and can readily be decontaminated is presented in the form of a flat parallelipipedal box. The top plate 2 of the box-mattress unit forms a table and is provided with a central depression of rectangu' lar shape having a chamfered periphery and dimensions which are substantially those of a patient who is lying in the horizontal position. The bottom of said depression is constituted by a transparent plate 3 formed of Plexiglas, for example, and provided with drainage channels 4; said plate 3 is supported on a bearing member 5 which is provided at the base of the chamfered portion to which it is secured in fluid-tight manner by means of bolts and neoprene seals (not shown).

The patient rests on an articulated stretcher 6 which is associated at each end, namely at the head end and foot end, with a complex mechanism which makes it possible in particular to place the patient in the desired angular position and to turn the patient over longitudinally. Detailed descriptions both of said stretcher and of said mechanism will be given hereinafter.

The table 2 is completely surrounded by a cylindrical channel 7 which has an opening at the top and contains an air-seal 8, the inflation valve of which is shown at 9. Said air-seal is formed in one piece and may be made of flexible neoprene, for example. The rigidity of the seal must be sufficient to enable it to retain its shape and to permit of its ready extraction from the channel 7 by means of a device of the tire-lever type.

A Plexiglas frame 10 without either base or cover and having a substantially parallelipipedal shape is attached to the table 2 in fluid-tight manner. To this end, the lower end 11 of the frame walls is molded in the form of a beaded edge and is fitted in the air-seal 8 which, after inflation, locks the frame in position in a fully leak-tight manner. Handles 12 are provided for the purpose of fitting or removing the frame.

Provision is thus made for a fluid-tight enclosure which can serve in particular as a bath or shower chamber. With this object in view, perforated spray-tubes 13 are disposed along the chamfered portion of the central depression of the table 2. The design function of said spray-tubes is to douche the patient from underneath, dry the patient with dry air or simply to fill the bath.

A discharge pipe with strainer 14 is adapted to slide in leaktight manner through the transparent plate 3. In the bottom position (as shown in full lines), said pipe permits the complete emptying of the bath", in the top position (shown in chain-dotted lines), the strainer makes it possible to maintain the liquid at a constant and adjustable level within the enclosure.

A perforated horizontal spray-tube 15 can be fitted at the foot end of the table 2; said tube can be fed with either liquid or air in the same manner as the spray-tubes 13.

The Plexiglas frame 10 is fitted at the top with a stainless steel band 16 which clamps the frame walls and opens at the top into a channel 17 of cylindrical section which is similar to the channel 7 and in which is held an air-seal 18 of the same type as the seal 8, the valve for the inflation of said seal having been omitted from the figure.

The seal 18 permits the leak-tight attachment of an openbottomed hood 19 to the frame 10, the bottom of the hood walls being cut so as to form a beaded edge 20. Inasmuch as the systems of leak-tight attachment of the frame 10 to the box-mattress table 2 and of the hood 19 to the frame 10 are strictly identical, the hood 19 can therefore also be fixed directly to the box-mattress.

The hood, or so-called handling hood, is provided (as shown in FIG. 2) with ports 21 fitted with sleeves 22 and gloves 23 and at the top with inspection doors 24. Another glove port 25 is provided at the head end of the hood whilst provision is made at the foot end for an inwardly-opening door 26. When so required, said door is designed to permit the connection of a sterilization lock-chamber, not shown in FIG. 2. Handles 27 are provided in order to permit fitting and removal of the hood.

When the patient is within the sealed enclosure, he is supplied with respiratory mixtures by means ofa pipe 28 fitted in the table 2 at the head end. The vitiated air is discharged via two other pipes which are also fitted in the table 2, one at the head end (not shown), and the other at the foot end, as shown at 29. Holes (not shown) are intended to permit spraying of germicidal aerosols for the purpose of sterilizing the chamber prior to use. Sterilization can also be carried out by introduction of ultraviolet lamps within said chamber.

The box-mattress unit is additionally provided with a device which performs the function of a bed-pan. To this end, the Plexiglas plate 3 is provided substantially at the level of the seat with a circular opening 30 which can be closed by means of a cover 31. also formed of Plexiglas. Said cover is fitted around its periphery with an O-ring seal 32 which ensures leak-tightness under the action of small magnets such as 33 which are embedded in the cover 31 and the plate 3. The bedpan, which is designated in the figure by the reference 34, can be inserted at one end of the box-mattress unit and is designed to slide on rails 35 up to the opening 30. Said bed-pan is fitted around its periphery with an annular air-seal 36 which ensures leak-tightness after inflation The same rails 35 also serve for the displacement along the entire length of the plate 3 of a drawer 37 containing sensitized X-ray films.

The box-mattress table 2 is provided at the four corners with small vertical rods 38 for the engagement thereon of the four feet of an orthopedic frame 39 having dimensions which make it possible to fit said frame within the chamber walls. Said frame is provided in particular with a spring system (which is similar to a dynamometer) as shown diagrammatically at 40, whereby a tractive force of adjustable intensity may be exerted on a fractured limb. In the apparatus according to the invention, said spring system advantageously replaces the weight systems usually employed for this purpose by virtue of its small overall size.

As shown in detail in FIG. 3, the stretcher 6 is made up of a main frame 41 fitted with detachable cross-bands 42. Said cross-bands each have one rigid extremity in order to slide them beneath a seriously injured patient to be transported without any need to handle the patient.

The main frame 41 therefore comprises two identical articulations at the points shown in the figure at 43. Toothed locking systems such as the system 44 which are associated with the articulation points serve to hold the patient in the horizontal position as well as in any raised position.

A small additional frame 45 can be adapted beneath the frame 41 at the level of the central portion thereof. The points of attachment of said additional frame to the frame 41 coincide with the articulation points 43. By this means, the stretcher is endowed with rigidity when an injured person is resting thereon.

The two frames can also be provided at different points with drilled holes such as the holes 46 and 47 in order that different types of appliances for immobilizing the patients limbs in a predetermined position may be fitted on the stretcher. By way of example, two appliances of this type are shown diagrammatically in FIG. 1 at 48 and 49: the appliance 48 which is attached to the frame 45 can serve to immobilize one of the patients arms; the appliance 49 is designed in the form of a bridge and is attached to the two side members of the main frame 41 for the purpose of supporting the patients knees.

At both ends of the main frame, provision is made for two bosses 50, the function of which will be explained in the description which follows.

A part ofthe main frame 41 can be disassembled at the head end by means of a system which is shown diagrammatically at 51 so as to permit the adaptation ofa special support for cranial surgery. This support is shown at 52 in FIG. 1.

The stretcher is supported at both ends, namely at the head end and foot end, on transverse rails 53 by means of hooks 54. It is thus possible to displace the stretcher laterally along said rails for such a purpose as to make the patient more accessible for any care and treatment required. A locking mechanism serves to secure the stretcher in any desired position. Said mechanism comprises a member 55 which is fitted at one end with a suction cup 56 permitting its attachment to the top plate or table 2 of the box-mattress unit and, at the other end, with a toothed portion 57 which is brought to bear on one of the cross-bars of the frame 45, said cross-bar being provided with a series of identical teeth 58.

The rails 53 are rigidly fixed at each end to a shoe 59 which is slidably mounted on a longitudinal rail 60 and which can be locked on said rail by means of a screw 6]. There is thus provided a possibility of lateral displacement of the stretcher as well as a possibility of longitudinal displacement.

The rail 60 is pivotally attached to a vertical support bracket 62 by means of a pin 64, said vertical bracket being rigidly fixed to a base-plate 63 which also serves as a support for the opposite rail. Said rail 60 is secured to said support bracket in the horizontal position by means of a locking-pin 65.

The base-plates 63 at the head end and foot end are supported at both extremities thereof on two jacks 66 (shown in FIGS. 1 and 2) which are attached to the top plate 2 of the box-mattress unit through which they pass. Since the jacks can be operated independently both at the head end and foot end, the injured patient may be placed in all the positions required both by his physical condition and by the type of 'medical treatment to be given. As and when said jacks perform different movements, the shoes 59 slide freely along their rail 60 so as to compensate for the lack of metal which results from the different movements of rotation about the articulations 43.

The removal of the locking-pin causes the rail 60 to swing about the pivot-pin 64 in the direction of the arrow F.

Thus, the hooks 54 are released from the rail 53 and the two reversal mechanisms shown diagrammatically at the two extremities of the stretcher in FIG. 1 can then be connected. A description of these mechanisms will now be given in detail with reference to FIGS. 4 and 5.

The two mechanisms referred-to are identical: they each comprise a bearing 67 which is attached to the base-plate 63 by means of bolts (shown at 68 in FIG. 3) and in which a frame 69 is capable of rotating about its shaft 70. The dorsal stretcher 6 (illustrated in FIG. 3) is gripped at both ends by means of clamps 71. In the same way, identical clamps 72 imprison the extremities of a second stretcher 73 or so-callcd ventral stretcher. This stretcher is not shown in the drawings, but consists of a simple non-articulated frame fitted with cross bands 74 which are identical with the cross-bands 42 of the stretcher 6.

Columns 75 which are rigidly fixed to the frame 69, serve to guide the clamps 71 and 72. A screw 76, whose upper pitch 76 and lower pitch 78 are opposite, is held to the frame 69 at the two extremities thereof and traverses the clamps. Said screw is actuated by means of a removable handwheel 79. A nut 80 serves to close the clamps whilst the separation of the clamp jaws is facilitated by means of an oppositely-acting spring 81. By means of a small latch 82 which is intended to engage in a recess formed at the base of each of the two nuts 80, the nutclamp assembly can be locked in position in such a manner that the stretchers can be moved towards or away from each other simply by operating the screw 76.

A locking system makes it possible to immobilize the two stretchers in different positions, one stretcher being shown diagrammatically in chain-dotted lines in FIG. 2. This system is constituted by a retractable locking-pin 83 fitted with an oppositely-acting spring 84 fixed to the bearing 67, the extremity of said pin being adapted to engage in holes such as the hole 85 which are disposed around the entire periphery of the frame shaft 70.

In addition, in order to prevent sliding of the stretchers at the time of reversal operations, the bosses 50 which are provided at both ends of the dorsal stretcher are centered in recesses 86 (shown in FIG. 5) which are formed in the clamp 71. The same bosses and the same recesses can also be provided on the stretcher 73 and the clamps 72.

The member which is shown at 87 in FIG. 4 is centered around the screw 76; said member comprises two retaining heads 88 and 89; the head 88 serves to attach a cable 90 which can be employed, for example, for applying tractive efforts on the patients spine, whereas the head 89 is coupled to the cable 91, from the end of which is suspended a traction device (which is identical in design to that which is shown diagrammatically at 40 in FIG. 1). Elongated slots 92 which are formed at the center ofthe member 87 permit ofsufficient dis placement of said member at the time of application of traction.

The frame I of the box-mattress unit is supported on a carrier-frame 93 (FIGS. 1 and 2) fitted with shock-absorbers (not shown) and with wheels 94 by a mechanism which permits the inclination of the box-mattress frame in a large number of different positions. Said mechanism is constituted by a universaljoint assembly 95 which is disposed at the head end and at the center of the box-mattress frame 1 and by two lifting plungers 96 which are associated with a universal-joint assembly 97 and which are disposed at the foot end at an equal distance from the center.

The carrier-frame 93 contains different conditioning devices for air-purification and sterilization, oxygen cylinders, a unit for supplying the bath with water at different tempera tures as well as the motors for actuating the jacks together with their feed systems. The different feed systems are passed in fluid-tight manner through the base-plate of the box-mattress frame by means of bellows seals 98. The apparatus thus constitutes a fully self-contained unit.

The apparatus according to the invention can additionally comprise a series of small open-ended asepticizable casings,

not shown in the figures. Said casings, which are movable and interchangeable, can be mounted in a fluid-tight manner by means of air-seal systems of the type hereinabove described, either directly on the box-mattress table 2 or on the Plexiglas frame 10. The intended function of said casings is to provide separate chambers in which different forms of local therapy may be applied simultaneously.

The advantages of the apparatus according to the invention over existing equipment will become more readily apparent from the following description of one example of operation when it is employed for a road accident victim who is in a state of shock and unconscious, who is suffering from burns, open fractures, contusions and multiple wounds.

In the present state of the art, the injured person is lifted by hand and placed on the ambulance stretcher. A perfusion is then carrried out by cutting a part of the patients clothing and oxygen therapy is then applied with a mask. The stretcher is carried into the ambulance, then removed from the ambulance into the open air upon arrival at the hospital. Throughout this transportation period, the patient is liable to suffer from the cold and the burned tissues are liable to become infected. At the hospital, the patient is first carried to an admission table, undressed, washed with dispatch, treated for shock and then given a blood transfusion. The patient is then transported into an X-ray room, placed on the X-ray table and transported once again to the operating room in which he undergoes the different treatments which are necessary (dressing of burns, osteosynthesis, etc.) before being finally laid in bed. Under such conditions, it is difficult to give a patient the simultaneous advantages of a sterile enclosure, an oxygen tent and an appliance for retaining fractures in place. Difficulties are involved in providing the proper medical care, washing of the patient is virtually impossible and atmospheric contamination will frequently arise. When the nature and extent of the injuries make it necessary to transfer the patient to a distant center for special treatment, retention of fractures must be stopped, the patient must again be handled a number of times, placed again in an ambulance and transported under unfavorable conditions; all equipment and appliances must again be reinstalled in the new center which may in turn be inadequately equipped for treating fractures.

The apparatus in accordance with the invention dispenses with the need for such an excessive number of handling operations and makes it possible under the best conditions to carry out all the medical care, treatment and surgical operations which a patients condition requires. Thus, when a wounded person is lying on the ground, the main frame 41 of the stretcher is placed round the persons body. The cross-bands 42 are then passed under the body, sliding of the bands along the ground being facilitated by their rigid extremities. The cross-bands are then attached and the small central frame 45 is fitted in position: the wounded person then rests on a rigid stretcher which can be placed on the rails 53 by means of the hooks 54. The Plexiglas frame 10 is titted on the box-mattress unit and locked by inflation of the air-seal 8. After preliminary sterilization, the handling hood 19 is also locked on said frame. The patient is then immediately placed in an air-conditioned, sterile and superoxygenated atmosphere. From this moment, most forms of medical and surgical treatment which are necessitated by the patients condition can be carried out in any location without entailing any need to open the chamber. The patient can be undressed, douched, bathed and then dried with dry and sterile air. X-ray photographs can be taken and fractures can be immobilized. The combined operations of the jacks 66 and of the mechanism for inclining the box-mattress unit (plungers 96 and universal joint assembly make it possible to hold the patient in any desired positron.

In some cases, it proves necessary to turn the patient over to the ventral position. The two reversal mechanisms are accordingly placed in position on the plates 63 by means of the nuts 68; the locking-pins 65 are removed and permit the downward motion of the rails 53. The main stretcher is taken at both ends within the clamps 71, the bosses 50 being centered within the recess 86. The ventral stretcher 73 is also secured within the clamps 72. The small locking bolts 82 are thrust within their recesses and the hand-wheel 79 is then operated so as to move the two stretchers towards each other so that the patient is fully supported.

It then only remains to actuate the four jacks 66 simultaneously in order to lift the complete assembly, thereby permitting the movement of reversal about the axis 70 and in such a manner that the main stretcher 6 is not hindered in its movement of rotation by the Plexiglas plate 3.

Thus, the patient will have been handled only once at the time of placing in the apparatus. Should an anuria or skin graft justify transportation of the patient to a specialized center, it would accordingly be possible to effect such transportation without the need of any further handling or interruption of the treatment in progress.

It is apparent that the foregoing description has been given by way of explanation but not in any limiting sense and that any detail modifications could be contemplated without thereby departing either from the scope or the spirit of the invention.

For example, it will be readily understood that different forms of distribution tubes which can be supplied either with air, respiratory mixtures or various liquids can also be fixed on the apparatus and that it would also be possible to make provision for a system for weighing the patient, said system being fitted either beneath the universal joint assembly 95 or beneath the jacks 96.
