Definitions

  • the invention relates to a control device for successively filling individual chambers with a gaseous medium.
  • individual chambers can be, for example, flexible, hose-like chambers combined into a sleeve.
  • the cuffs formed in this way are used, for example, for decongesting extremities, for example arms or legs. For this it is necessary that all chambers are filled with the gaseous pressure medium one after the other. The next chamber may only be filled when the previous chamber has reached the desired pressure.
  • Known control devices which should enable such successive filling of the individual chambers, are very complex and expensive and do not always work satisfactorily.
  • the invention is therefore based on the object to propose a control device of the type described above, which is extremely simple in construction, works absolutely reliably and can be expanded while maintaining the basic components so that any number of chambers can be filled in the desired manner.
  • control device of the type described in the opening paragraph with the characterizing features of the protection claim.
  • This is based on a control device according to utility model G 84 15 045.9.
  • the present application can be seen in the fact that the control device is regarded as a component according to the protection claims of the utility model mentioned, several such components being linked together to produce a new overall control device which consists of the linked individual components. By lining up (chaining) these individual control devices, a new overall unit is created, which can be expanded or reduced in any way and can therefore be adapted to any number of chambers to be filled in the simplest way, without the control device as such becoming more complicated and without losing the beneficial effect of the individual components.
  • FIG. 1 shows a control device, from which it is initially to be assumed that the control body used there should be the control body 14, that is to say a cylindrical control body in the illustration according to FIG. 3 or FIG. 4.
  • the entire length of the cylindrical control body 14 is covered with a tubular rubber skin as membrane 29 (see Figure 1a).
  • the control body 14 coated in this way with the membrane 29 is inserted with radial play in a tubular hollow body 17 which is approximately the same length as the control body 14.
  • This hollow body 17 has a radially directed inlet opening 37 in the vicinity of the rear end, which is equipped with a hose connection piece 41 is.
  • Hose connector 41 is connected to the pressure source 42 for a flow medium via a control pressure line 12 and via pressure regulating devices (not shown).
  • the radial space between the outer surface of the membrane 29 and the inner surface of the hollow body 17 is sealed in the region of the two ends of the hollow body 17 with an O-ring 25 and 26, respectively.
  • the control body 14 has a number of annular channels 33 on its surface, which are delimited by annular intermediate webs 32. In each of these annular channels 33 there is an outlet opening 34 and 35, each subsequent outlet opening 34 preferably being arranged somewhat offset in the circumferential direction with respect to the previous outlet opening 34.
  • An inlet connection 1 and the outlet connections 2 to 10 are arranged on the end 22 of the control body 14 from the end and distributed in the circumferential direction (see FIGS. 1 a and 3).
  • the connections 1 to 10 mentioned are each connected to the outlets 34 and 35 via longitudinal bores in the control body 14.
  • So z. B. (see Figure 1) the inlet port 1 connected to the outlet 34.
  • the inlet connection 2 is connected to the lowest outlet 35 in FIG. 1, etc.
  • This outlet port 11 can directly into the free Lead atmosphere 38, or serve as a connector to other devices, in the embodiment with a silencer 43.
  • the O-ring 25 before the first outlet that is before the outlet 34th
  • the 0-ring 26 is arranged behind the last outlet, that is to say behind the outlets 36 which lead into the outlet connection 11.
  • the outlet connections 2 to 10 are each connected to an associated individual chamber 39 via suitable lines, all of the chambers 39 being combined to form a sleeve 40.
  • These individual chambers can z. B. form annular tubes so that this sleeve 40 z. B. can be placed over an arm or over a leg.
  • the inlet connection 1 is connected to a pressure source 44 which is suitable for filling the chambers 39 and thus the sleeve 40 with pressure medium in the desired manner.
  • the control body 15 used there essentially corresponds in its construction to the control body 14. However, it does not immediately have the desired connections on its end face 19, like the control body 14, but rather a connecting disk 16 is provided there, which is either sealed off from the control body 15 or is formed in one piece with it.
  • control body 13 is designed as a plate-shaped body with a rectangular cross section.
  • the plate-shaped body 13 is also encompassed by the membrane 29.
  • membrane 29 can be designed as a piece of tubing, since the flexible membrane 29 easily adapts to the body shape of the control body 13.
  • straight channels can be incorporated on one side of the control body 13, similar to the channels 33 according to FIG. 1.
  • the illustration according to FIG. 1 can also be seen as a view in the direction of arrow A according to FIG 1 shows the course and the arrangement of the channels 33, as they are to be used in FIG. 2. Complete channels are then not required.
  • outlets 34 and 35 assigned to the connections 1 to 10 can again be seen in an arrangement which is shown in FIG.
  • Each of these connections 1 to 10 is connected to the associated outlet 34 or 35 via a longitudinal bore.
  • the last channel with the outlets 36, which are assigned to the outlet connection 11, is no longer shown in FIG.
  • the arrangement can also be seen in FIG. 1 if it is assumed that FIG. 1 is a view in the direction of arrow A in FIG. 2.
  • the changed body shape of the control body 13 makes it useful to design the hollow body 18 corresponding to the body shape of the control body 13.
  • the inner cross-section of the hollow body 18 is again somewhat larger than the outer dimensions of the control body 13, so that the intermediate space can again be provided with a seal in the front and rear area in the position already described for FIG. 1, also in this case the seal can be an O-ring 27 or 28, which is sufficiently elastic to adapt to the shape of the control body 13 and the hollow body 18.
  • the hollow body 18 is drawn broken, it expediently includes the control body 13 completely, but leaves the end cross-sections outside of the seal open.
  • the hollow body 18 is again equipped with an inlet opening 37 in the approach shown in FIG.
  • this inlet opening 37 again has a hose connector 41 and is connected via a control pressure line 12 to the pressure source 42 already mentioned.
  • This flat design according to FIG. 2 enables it to be designed as a plug-in module and also makes such a control unit stackable in a simple manner.
  • the embodiment according to FIG. 2 also makes it possible to combine such control units into batteries in a particularly advantageous manner and to couple them together if required.
  • the outlet connection 11 provided on the end face 24 is connected to the inlet connection 1 of the next control unit via an intermediate line.
  • a pressure source 44 suitable for this purpose must first be connected to the inlet connection 1, for example of the control body 14.
  • the pressure medium supplied by the pressure source 44 then exits at the outlet 34 and into the associated ring channel and expands the membrane 29 as soon as the ring channel is filled. Due to the expansion of the membrane 29, the pressure medium can now exceed the first annular intermediate web 32 and enter the next annular channel and there enter the first outlet 35 and fill the first individual chamber 39 via the assigned outlet connection 2.
  • control line 12 and the inlet opening 37 in the hollow body 17 or 18 can act on the membrane 29 from the outside with control pressure.
  • a greater internal pressure is required to lift the membrane off, so that the pressure medium supplied by the pressure source 44 is the next channel enough.
  • the desired internal pressure of the individual chambers 39 can thus be easily adjusted.
  • the setting is extremely precise.
