y 1959 .R. H. BATES ET AL PHYSICAL THERAPEUTIC APPARATUS Filed Jime 28, 1956 INVENTOR. ROLLANDMBATES BY CARL PANTERMOLLER COMPRESSOR MM t qfforneys PHYSICAL THERAPEUTIC APPARATUS Rolland H. Bates and Carl Pantermoller, Milwaukee, Wis.
This invention relates to a physical therapeutic apparatus and more particularly to an apparatus in which fluid pressure is applied to spaced locations of the body in alternate sequence.
The physical therapeutic apparatus of the invention is designed for massaging or stimulating the circulation in a portion of the body to which the apparatus is applied. Fluid pressure is adapted to be alternately applied to adjacent areas of the body and this effects a pulsating or massaging action which stimulates the circulation of the blood in this area.
According to the invention, the apparatus comprises a rubber or plastic sheet composed of two separate layers which are sealed together at spaced locations to provide a series of generally curved passages which extend the length of the sheet. Alternate passages are connected to a source of pressure and the intermediate passages are separately connected to the source of pressure. With this construction, fluid pressure is alternately applied to each set of passages while the pressure in the intermediate passage is released. This pressurizing and de-pressu-rizing action results in a massage-like treatment and stimulates circulation in the area of the body to which the apparatus is applied.
In a small form the apparatus can be Wrapped around a limb of the body, or in a larger. form it can be used as a mattress. As a mattress, the device is particularly useful for persons confined to bed for extended periods, for the pulsating action alternately applies pressure to difierent portions of the body and thereby prevents bed sores which generally result from the constant pressure and abrasion of the 'bed against the skin.
Bed sores are aggravated by perspiration and constant pressure. For example, if the bed linen is wrinkled, the
wrinkles exert an increased pressure on the body and bed sores are likely to occur if this pressure is maintained against the body for extended periods of time. With the use of the present invention as a mattress, the constant pressure on the body is eliminated, for a given area of the body is subjected to periods of pressure followed alternately with periods of non-pressure. During the non-pressure periods the mattress is actually out of contact with the body area and an air pocket is formed between the body area and the mattress which acts to prevent the formation of bed sores.
In the smaller form, the device maybe applied to a limb or other portion of the body for the massage and relief of aching muscles, sprains or the treatment of polioatlected limbs. The present invention is particularly useful in the treatment of polio patients in which the activity of the limbs is affected and extensive periods of massage are required. In this situation, the apparatus can be conveniently secured to the affected limb and the massaging action is automatically applied for any desired period of time.
The drawing illustrates the best mode presently contemplated of carrying out the invention.
In the drawings:
2,896,612 1C6 Patented July 28, 1959 Figure 1 is a fragmentary top plan view of the invention;
Fig. 2 is a diagrammatic representation of the invention as applied to a leg; I
Fig. 3 is an enlarged fragmentary diagrammatic showing of the pressure connections; and
Fig. 4 is a transverse section taken along line 44 of Figure l. i
The drawings illustrate a' flexible sheet 1 which is formed of two separate layers 2 and 3 of rubber, plastic or any other similar flexible material. The layers 2 and 3 are bonded together along their edge portions, as indicated by 5, and are bonded together at spaced intervals, as indicated by 4, to provide a series of passages 6 and 7 which extend substantially the length of the sheet 1. The layers 2 and 3 can the bonded at 4 and 5 by the application of heat and pressure, by the use of adhesives or by any other conventional bonding process commonly used with the material of the layers 2 and 3.
The ends of the passages 6 and 7 are closed off, as indicated by 8, by the bonded edge portion 5. The passages 6 and 7 have a generally curved configuration and, as shown in Figure 1, take the form of a sine curve. The passages 6 and 7 are disposed immediately adjacent to each other with just the necessary amount of material extending between the passages in order to provide the seal 4. The passages extend substantially the entire width of the sheet 1 with the number of passages being determined by the width of the sheet.
The curved shape of passages 6 and 7 provides an improved pressure distribution whereby pressure is applied to areas of the body through passages extending in a number of directions rather than a single direction as would be the case if the passages 6 and '7 were straight. This pressure applied along cross or transverse lines as well as longitudinal lines results in a more eifective massaging action with a better feel to the patient.
The series of passages 6 are adapted to be pressurized alternately with respect to the passages 7. To supply pressure to the passages 6, a nipple 9 is secured to the outer open end with each of the passages 6 and a plastic or metal tube 10 is engaged with the nipple 9 by means of a coupling 11.
Each of the tubes 10 communicating with the corresponding passages 6 are connected to a manifold 12 and the manifold in turn is connected through a coupling 13 to the outlet 14 of a four-way valve 15 In a similar manner, a nipple 16 is secured Within the outer open end of each of the passages '7 and a tube 17 is threadedly engaged with the nipple 16. The tubes 17 are connected to a manifold 18, and the manifold is connected by means of a coupling 19 to an outlet 20 of valve 15.
The valve 15 is also provided with a pressure inlet 21 and the inlet is connected through a coupling 22 to a conduit 23. The conduit 23 provides communication with an air compressor which is shown diagrammatically, and indicated by 24. A suitable pressure regulator 25 may be disposed in conduit 23 to regulate the pressure of the air or other fluid.
The four-way valve 15 is also provided with an exhaust outlet 26 which opens to the atmosphere.
In operation of the apparatus, compressed air or other fluid is introduced from the compressor 24 through conduit 23 to the valve 15. The valve 15 is of conventional construction and can be operated either manually or by a suitable timing mechanism.
The air entering valve 15 is initially permitted to pass through outlet 14 to passages 6 while the flow of air through outlet 20 to the intermediate passages 7 is closed. Passages 6, being pressurized, expand to their greatest diameter and apply pressure to the corresponding portion of the body. This is best seen in Fig. 4, where the alternate passages 6 are shown expanded to a generally circular shape and the intermediate passages 7 are in collapsed state and therefore the portions of layer 2 defining passages 7 are generally not in contact with the body.
After a given period of time, which may generally be a matter of minutes, the outlet 20 in valve 15 is opened to admit air under pressure to passages 7 and, at this time, both passages 6 and 7 are pressurized. After a short period of time, which may be a matter of seconds, valve 15 is actuated to connect the exhaust outlet 26 with the outlet 14 so that the air under pressure in passages 6 is exhausted to the atmosphere. This results in passages 6 being deflated and the portion of the sheet defining passages 6 moves out of contact with the body and there fore, the pressure is applied to the body only through the passages 7.
After a given period of time, pressure is again introduced into the passages 6 and subsequently released within passages 7. This alternate pressurizing and depressurizing within the passages is repeated throughout the treatment.
It is preferred that both sets of passages 6 and 7 be pressurized before the pressure in one set is released so that there will be continual support given to the body at all times. This feature is particularly important when the device is used as a mattress in order to prevent the body from raising and lowering with each change of pressure.
The apparatus, as shown in Figure 1, can be used as a mattress, or if made in smaller size can be applied to a limb or other area of the body. As shown in Fig. 2, the device is wrapped around the calf of a leg and may be held on the leg by strings, clamps, etc. which are not shown.
The device provides a pulsating action in which pressure is applied to alternate adjacent portions of the body. This feature of applying pressure to alternate portions of the body aids in stimulating blood circulation and effects a gentle massaging of the body.
The invention is relatively inexpensive to produce and may be readily put into operation with a minimum of handling and labor. In contrast to whirlpool baths and the like, the apparatus can be conveniently transported and stored in a small area.
While the above description is directed to the use of air pressure, any other form of fluid pressure may be employed, and similarly, While the passages 6 and 7 are shown as having a sinuous or undulating form, it is con templated that the passages could be provided with any other desired type of directional deviation or geometrical pattern. Furthermore, it is contemplated that the tubes and 17 and the manifolds l2 and 13 could be formed directly in the sheet 1 rather than being separate elements as shown in the drawings.
Various modes of carrying out the invention are contemplated as being within the scope of the following claims particularly pointing out and distinctly claiming the subject matter which is regarded as the invention.
