Definitions

  • ABSTRACT OF THE DISCLOSURE vA physiotherapeutic instrument particularly for massage purposes having a sleeve adapted to be laid against the parts of the human body to be treated and which includes a multiplicity of air chambers which can be filled separately and which is connected with a compressor together with a control device having a rotatable distributor and regulating means acting on the control device to change the sequences of the compressed air to the air chamber.
  • This invention relates to a physiotherapeutic instrument suitable for massage, having at least one sleeve capable to be laid against the parts of the body to be treated, said sleeve being provided with a multiplicity of air chambers that can be filled separately, and with a compressor for producing compressed air. Also a control arrangement is provided which carries the compressed air to the air chamber in the sequence of their arrangement, one after the other, and which will let said air under pressure out again as soon as the second following air chamber or else one that is even still farther ahead will be filled, so that a progressive shifting of the pressure takes place along the sleeve.
  • the instrument is equipped with regulating means acting upon the control arrangement, for the change of the temporal sequence of feeding in of the compressed air into the air chambers and, thus, for the regulation of the speed of migration of the pressure shift.
  • control device contains further means for the throttling of the air stream in at least that spot in the flow path leading to the air chambers, which means will cause a throttling of at least the inflow to the air chambers at least over a part of the entire inflow period.
  • a distributor which distributes the compressed air to the feed lines of the individual air chambers.
  • the throttling means will partly cover up the feed openings during the feed in of the compressed air during a part of the entire inflow time, so that the inflow of the air into the air chamber during this part of the inflow time will be throttled.
  • the distributor mouth which can be moved past the feed-in openings, can advantageously be equipped with a control slot extending in the direction of movement and used as a throttling means, said slot covering the feed openings over a part of its entire length.
  • a control slot can, at the same time, be developed, in such a manner that its length is at least equal to the distance of two adjacent feed-in openings, and that its cross section of flow will increase counter to the direction of movement of the distributor, so that during the movement of the distributor past one of the feed-in openings, the cross section of flow of that part of the control slot located at any one time before the feed-in opening, will increase.
  • the removal of air from the air chambers can also take place advantageously by means of the above mentioned feed lines and there can be provided for this purpose, a second control slot for the removal of air on the distributor behind the control slot for the feed in of compressed air, the flow cross section of said second slot also increasing counter to the direction of movement of the distributor.
  • the instrument may be equipped advantageously with means for regulating the pressure of the compressed air fed to the air chambers.
  • means for regulating the pressure of the compressed air fed to the air chambers are especially important for the purpose of adaption to the physical constitution of the patient, because, for example in the case of obese patients, with their veins lying deep, a greater pressure should be applied than in the case of lean people where the veins are located directly below the skin.

  • the pipes 5 are distributed in two rows of twelve pipes 5 each.
  • the plate 7 is located on the outside of a transportable housing 8 as a mounting, which housing encompasses all construction elements shown in FIG. 1, except for a sleeve 9 with lines 10 and a plate 11 with pipes 12. With this plate 7 can be connected, in a manner to be explained, various plates 11, depending on the size of the sleeve 9 to be used, the plate 7 representing the pressure tapping point of the housing 8.
  • the pipes 4 and 5 are connected with one another in such a manner, that the lines 6 of adjoining pipes 4 are attached in one sequence to likewise adjoining pipes 5.
  • the pipes 4a, 4b, 40, FIG. 2 are thus connected with the pipes 5a, 5b, 50, FIG. 1.
  • the twelfth pipe 4x is connected with the twelfth pipe 5x, that is to say, the last one in the series shown.
  • the thirteenth pipe 4y is connected with the thirteenth pipe 5y, not shown.
  • the thirteenth pipe 5y lies like a cover behind the pipe 52: or 5a in FIG. 1 and represents the beginning of the second row of pipes 5.
  • the two rows of pipes are in parallel to one another.
  • the twenty-fourth pipe 4z is connected with the twenty-fourth, not shown, pipe 52.
  • the twenty-four pipes 5 have been placed in two rows for reasons of space saving.
  • the control slide 2 rotatable around the axis 13, is driven by an electric motor 14 through an infinitely variable gearing 15.

  • the control slot 25 serves as a duct of the compressed air from the control slide 2 to the sleeve 9, FIG. 1, and the control slot 26 serves for a controlled outflow of the compressed air from the sleeve 9 to the inside of the housing 1 and through an opening 28 into the open air.
  • the flow cross section of the control slot 25 has been developed in decreasing form, pointing into the rotational direction 27; the same being true of the control slot 26.
  • the two pipes 41) and 4c are supplied with compressed air, and compressed air flows from the sleeve 9 through the pipe 4a, housing 1 and opening 28.
  • the sleeve 9 has eight individual gas chambers, that is, in the example eight compressed air chambers 29, FIG. 1.
  • Each chamber 29 stretches in the transverse direction of the sleeve, the individual chambers 29 lie parallel one to another and they may be formed, for example, by vulcanizing or glueing.
  • the individual chambers 29 are separated air tight one from the other, and each chamber 29 has a line 10 connected thereto, FIG. 1.
  • the ends on one side of the lines 10 connect into the plate 11.
  • the sleeve 9 with lines 10 and plate 11 will result in a unit that can be' attached to or removed from housing 8, FIG. 1.
  • a plate 11 with eight pipes 12 has been attached to sleeve 9 provided with eight chambers 29.
  • the method of operation of the device according to FIGS. 1 to 4, in the case of an example according to FIG. 5, will be as follows.
  • the sleeve 9 with the eight chambers 29, placed around a line 31 that can be compressed, is to serve for the movement of a liquid 32 in the direction of the arrow 33.
  • compressed air flows from the chamber 29a by line 10, pipe 5a, line 6, pipe 4a and opening 28, into the open air (FIGS. 1 and 5A).
  • the compressed air escapes in throttled condition from the chamber 29a according to FIG. 5A, since the pipe 4a will be opposite to the small flow cross section of the control slot 26, FIGS. 3, 4.
  • the hose 31 may expand at the spot of the chamber 29a and will suck in liquid.
  • the chamber 2% is connected with the pipe 4b by means of the pipe 5b, and said pipe 4b will be opposite to the large flow cross section of the control slot 25, FIGS. 1, 3, 4 and 5A.
  • the chamber 29b is under full pressure and has closed the hose 31, so that the liquid 32 cannot flow counter to the direction of the arrow 33, for example as a result of gravity.
  • the chamber 290 will be supplied with compressed air, since it is connected with the pipe 4c by means of the pipe 5c, whereby the pipe 4c is opposite to the tapered flow cross section of the control slot 25, FIGS. 1, 3, 4 and 5A.
  • the compressed air flows throttled from the control slide 2 into the pipe 46, so that the hose 31 will be compressed at the chamber 29c, while displacing the liquid, FIG. 5A.
  • the compressed air will have flowed out entirely from chamber 29a, the pipe 4b is connected with the control slot 26, and the chamber 290 is completely under pressure by means of the pipe 4c.
  • the pipe 4d will be opposite to the narrow slot of the control slot 25 and the chamber 29d of the sleeve 9 is now fed compressed air in a throttled manner, FIGS. 3 and 5B.
  • the liquid 32 has been moved further by the width of one chamber in the direction of the arrow 33, FIGS. 1 and 5.
  • the next position is then shown in FIG. 5C.
  • next chamber 29e is supplied with throttled compressed air, since the pipe 4e is opposite to the control slot 25. From FIG. 5 it is apparent that always one spot or section of the sleeve 9 will completely close the hose 31 and that this closing spot or section progresses like a wave in the direction of the arrow 33 within the sleeve. In FIG. 5A this spot is located near the chamber 29b. In FIG. 5B the spot or section lies by the chamber 290, and in FIG. 5C it is the spot or section by the chamber 29d.
  • the length of the control slot 25 is equal to the distance of three adjoining pipes 4, FIGS. 3 and 4. That means at the most, three pressure release openings 4 can be opposite the control slot 25 and can be supplied with compressed air. This is done for reasons of inertia of the flowing air. Although, according to the illustrations in FIG. 5, always only two chambers are supplied with compressed air, the pipe 4d will be opposite the control slot 25 after a slight further turn of the slide 2, according to FIG. 3, whereby the pipe 4b will also still be supplied with compressed air.
  • FIG. 6 shows another design of a control slide 34 in a simplified form in the case of a straight line shift in the direction of the arrow 35 as compared to the stationary pipes 36, 37 and 38.

  • the length of the control slot 39 is equal to the distance of two adjoining pipes 36, 37 and 38 and so on.
  • the flow cross section of the control slot 39 is to remain the same across the whole length.
  • the full air pressure is eilective in both pipes 36 and 37 and the chamber 41, connected with the pipe 36, has completely compressed a hose 42, FIG. 7.
  • the chamber 43, connected with the pipe 37, has likewise compressed the hose 42 completely.
  • the continuous pressure wave in the sleeve 9 will show fairly precipitate transitions of pressure increase and pressure decrease. This strong pressure wave is particularly suitable for healthy tissue and thus as a preventative massage and less as a therapy.
  • a sleeve 9 with eight chambers 29 has been shown in FIG. 1. Altogether twenty-four gas chambers 29 can be attached to the housing 8, these twenty-four chambers can be distributed in a different number of sleeves. It will be advantageous to develop sleeves with six, twelve and twenty-four chambers.
  • the sleeves can be placed, for example around the arms, legs and buttocks.
  • the sleeves have to be placed in such a manner on the part of the body, that the pressure wave (arrow 33 in FIG. 1) in the sleeve 9 will move in the direction toward the heart.
  • the venous blood of the great blood circuit returning to the heart also flows in this direction.
  • the device can be used for correction of disturbances of peripheral circulation, for the following reasons;
  • the complete revolution or turn over of the blood which reaches the artery from the heart via a pulse wave and from here slowly flows back in the vein toward the heart is no longer guaranteed.
  • the blood particles which are not circulating may form a kind of a sump in the vein, and this sump may lead to thrombosis.
  • the carbonic acid containing dark blood which is in the vein will be moved in the direction of the heart with a compressed air sleeve attaching on the outside part of the body.
  • the hose 31 and 42 represents the vein.
  • any blood sump existing in the vein will be emptied out and all the blood will be rotated and, thus, will be carried back to the regenerating organ.
  • the passive congestion of blood just described occurs because vein flaps were no longer intact. A congestion of blood however can also occur in the case of extended sickbed condition or after a major operation. With the help of the device, the blood circulation can be maintained and thus serves for the prevention of thrombosis or embolism.
  • lymphatic vessels too may become inefiective in their functioning.
  • the muscular pumps are then no longer in a position to squeeze out the lymphatic vessels located between the skin and the bones, so that the blood and the collected wastes of metabolism can no longer be emptied out into the vein, in order then to be carried back to the regenerating organ.
  • seas of waste and sumps of waste with harmful effects will develop.
  • the lymphatic vessels are squeezed out and the wastes are carried to the catabolism organs.
  • the device will bring about an improved inflow of fresh blood because a suction will develop in the artery through an accelerated flow off of used up blood.
  • the device can be used as a preventative measure, in order to avoid accumulations of blood sumps. If ailments of the vein, lymphatic vessels and the arteries are present, then the non-circulating blood will be moved by means of the device and thus the blood sump will be carried back to the regenerating organs.
  • the communication speed of the pressure impulse developing in the sleeve must be small and a speed of about 0.2 to 0.4 m./ sec. has proven itself effective. With this speed of the pressure im pulse continuing as a pressure wave in the sleeve, the stagnating blood will be moved, for example in the vein toward the heart. In the case of the healing application of the device, one must compress and'decompress the arteries and veins gently, that .is the course of pressure must be rounded and must take place without any sudden transition.
  • the device does not need to take into consideration the pulsation and the rhythm of the heart, since in the above mentioned speed of propagation or transmission the pressure wave in the sleeve and the above mentioned pressures, both the pulsation of the artery as well as the rhythm of the heart of the vein close to the heart, is not impeded. Thus, the device is not controlled by the heart.
  • the known device mentioned in the beginning where the individual pressure impulses occur in the sleeve one after another, it will not be possible to move any stagnating blood at such a low transmission speed of the pressure impulses of 0.2- 0.4 -m./sec., since after each individual pressure impulse the blood can again flow counter to the direction of the heart.
  • the known device cannot be used for 'healing of already existing blood sumps but merely as a preventative treatment in the case of a general health massage.
  • Physiotherapeutic instrument suitable for massage comprising at least one sleeve adapted to be laid against the parts of the human body that are to be treated, said sleeve being provided with a multiplicity of air chambers that can be filled separately, a compressor for the production of compressed air, a control device with a rotatable distributor driven by a revolving motor to carry the compressed air to the air chambers in the sequence of their arrangement one after another and to permit the compressed air to escape again as soon as the second next air chamber or one lying even farther ahead is being filled, so that a shift of pressure continuing along the sleeve will take place, regulating means acting onthe control device for changing of the temporal sequence of the feed-in of the compressed air to the air chambers and thus for the regulation of the migration speed of the pressure shift.
