I Application December 29, 1942, Serial No. 470,429

11 Claims.

In case ofaccident to the human body, and particularly any accident characterized by broken bones, it is always important, and often of vital importance, to prevent any additional injury to the body in the course of transportation from the locus of the accident to a hospital or hospital base. In the case of broken bones, any serious displacement, before hospital treatment, beyond that produced by the accident itself, often produces conditions that make the remedial measures of the physician or surgeon more difii- 'cult and may, in some cases, prevent completely successful bodily repair. Indeed, in some cases, fatal outcomes arise not from the inherently serious character of the bodily injury, but from secondary injuries incurred during transport of the make it dimcult or impossible to correctly or completely diagnose the character or extent of the injuries at the locus of the accident.

A preferred embodiment of a the invention is shown in the accompanying drawing, in which-- Fig. 1 is a plan view of the carrier or stretcher.

Fig. 215 a side view of the same with a human body in position thereon and secured in rigid relation thereto.

Fig. 3 is a plan view of Fig. 2.

i Fig, 4 is a perspective view of the stretcher when not in use.

Fig; 5 is a perspective view of a detail.

The base comprises a flat board or plate preferably comprising two sections a and a hinged together so as to permit the foot section a to be folded under the main section a, as shown in Fig.

4, to attain compactness in transportation. The

any disturbance of such rigidity is to maintain H umn without involvement of injury to the spinal cord; any deviation from rigidity following the accident being attended with danger of injury to the spinal cord and consequent paralysis or death.

The object of my inventionis to provide a stretcher which includes equipment whereby the entire body, after careful deposit on the carrier or stretcher, may be readily and quickly secured thereto in such a manner as to insure; not only that the body will be maintained in fixed position on the carrier or stretcher, but also that all parts of the body will be maintained iniixed relative positions until the hospital base is reached. Incidentally, my improved stretcher is adapted to maintainfa broken leg or arm in fixed position relative to the body trunk, even though the equipment is not so manipulated as to hold the entire body rigid; but a primary advantage of the invention is its adaptability to guard against all secondary injuries where conditions base-board section a is provided with a slightly arched plate b extending along the longitudinal center of section a. This plate may be substantially narrower than the base-board but it is Wide relatively to its own thickness. Its deviation from flatness is just sufficient to give it a contour corresponding to the natural concavity of the human back.

The body is strapped to the base-board by means of straps e, c and d, 01 carried by the respective sections a, and a. The straps d, d are secured to arms 11', d, each of which is one member of a hinge the other member of which is secured to the face of section a of the base-board. Each member at is adapted to swing, from a position fiat'against the fixed member, upward into the vertical position shown in the drawing.

To maintain the body under longitudinal tension, the following means are provided to connect the hands and the feet. At the foot of section a is an arm e carrying a fork between the prongs of which are carried two pulleys g. The arm e is preferably formed by securing one member h of a hinge to the under face of the section a, the other member of the hinge (constituting the arm 2) being swingable, from a position under and fiat against the member it, through an arc of 270, into, but not beyond, the position shown in Fig. 2. Around each pulley g extends a rope 1 provided at one end with an extension or hitch which is engageable with the foot and ankle in known manner. The other end of the rope is provided with a loop is which is connected with the wrist by means of a strap. This strap is constructed as shown in Fig. 5. Between its ends it is formed into a closed loop in through which thehand is'slipped. One end m of the strap injuries.

is provided with a series of perforations m The other end 121, of the strap is provided with a buckle m slidable along the end m and adapted to engage any of the perforations. Before such engagement one end of the strap is slipped through the loop lc. Thereby the ropes i may be drawn taut to exert a downward pull on both the arms and legs, the body as a whole being thereby maintained under longitudinal tension,

To'further maintain body rigidity the baseboard is provided withan arm -n, secured-to about the center of the base-board (that is, near the lower end of section a) and adapted to engage the crotch at the junction of the legs to the body; and with two other arms and 0' located nearthe upper end of the base-board and adjacentits .opposite side edges. Each of these arms is preferably formed by hinges, one member of which .is secured to the face of the base-board and the other of which, constituting the arm specified'is adapted to swing into, but-not beyond, an'upright position. Eachof these rarms-isiproyided witha hook p and tension springsm'a-nd 'r' are .adapted to connect the hook of arm .n withthe hooks of arms 0 and 0 respectively.

Displacement of the head is prevented by :the followingmeans: secured to the base-board :near the upper end ther'eof and adjacent its opposite side edges are two arms s, s, which,-also, are preferably formed by hinges .one member of each of which is secured to the :-face of the base-board while the other member, constituting. the specified arm, is adapted to: swing into, :but. not beyond, an upright position. Fastened to the .arms s, s are straps t, t, which are adaptedto be .brought over the forehead and mutually en aged. .Two other straps u and u are fastened to the armsls. s, and are adapted to be brought under the-chin and mutually engaged.

In the event'that it is unnecessary, or for any reason undesirable (as .for instance in 1the:case of a broken leg or legs with uninjuredarm-s) t maintain the arms rigid or under longitudinal tension, the board is provided, at :its .QDDosite :side

edges, with two =cleats 17, mm lateral alignment, around which the ends of ropes i, i may -be wound, thereby maintaining longitudinal tension upon the legs. Kit is "thus possible to :maintain longitudinal tension upon either .or both legs, upon either leg and its corresponding :anm, or upon both legs and both arms.

Certain :of .the swingable hinge members, and particularly n, o and s, shou1d:be;padded to avoid possible harmful :pressure upon the :part of the body against which it is forcibly confined.

. All the described appliances cooperate :to hold the entire body in :the rigid condition required to prevent displacement 0f any broken bone, especially of the back or neck. Tranefeiwof the body from the locus of injury to :a hospital base may be attended, as hereinbefore described, with Zunavoidable jolting and jarring :movements of the base-board,v and other-deviations from radesirable, but impossible, horizontal position of ,rest. .Such movements, however, effect corresponding movements of the body lonlyras a unit, The various parts of the body'are notsubjecttorelative-movement and therefore are {not subject to secondary As shown in Fig. 4, *when the stretcher .isnot in use, the lower section a may beswungagainst the uppersection b andithe variousmoyablehinge members swung :down flat against .the fixed hinged members, therebyso reducing the .overall dimensions of thearticle that .ammnberof them may be readily carried to the locus of the accident.
