The invention relates to a pressurizable with under and / or overpressure chamber for receiving a part of the body of a person

• a manhole for inserting the part of the body into the chamber,
• a arranged at the manhole opening closure with a gas-tight hose, the front end of the hose is rotatably connected to a rotary ring,
• wherein the tube by oppositely rotating the front and rear end of the hose by means of the rotary ring on the body or the part of the body is brought into abutment.

Moreover, the invention relates to a closure for a pressurizable with under and / or overpressure chamber.

From the EP 1 002 510 B1 is a treatment device with a vacuum chamber for medical and / or cosmetic-physical therapy known. It serves to absorb the lower half of the body of a person and to apply a defined, pulsating negative pressure. The pulsating negative pressure causes an excitation of the blood circulation and decongestion of lymphatic loads. Furthermore, vacuum chambers are known with a smaller size, the only a body part, for example, receive an arm of a person.

The executed as a tube vacuum chamber has an entry opening for introducing the part of the Body, which is sealed by means of a closure against the trunk or the body part.

An Indian DE 199 12 611 C2 disclosed closure comprises a tube of gas-tight material in the technical sense, the rear end of the hose is fixed to the vacuum chamber and the front end of the hose is rotatably connected to a rotating ring rotatably mounted about a rotation axis. By mutually rotating the front and rear end of the hose with the help of the rotary ring of the tube is line-shaped on the body or the part of the body to the plant brought.

For gas-tight sealing of a vacuum chamber is also from the US 5,133,339 B a closure for the opening of a vacuum chamber is known, in which an inflatable ring in the region of the waist of a person standing in the vacuum chamber is brought by inflating the ring for conditioning. The inflatable ring has in particular an elliptical shape in order to adapt to the body as best as possible. In one embodiment of the closure of the inflatable ring is connected to an elastic band or elastic pants. The inflatable ring is disposed along the edge of the manhole in the vacuum chamber.

The from the US 5,133,339 B known closure is functional. The arrival and removal of the inflatable ring is cumbersome. In addition, the inflatable ring allows only small tolerances in the circumference of the waist.

The closure after the DE 199 12 611 A1 In contrast, it is much easier to handle and adapts to different body sizes without any problems. Due to the linear arrangement of the tube on the body or body part, however, it can lead to a cutting and thereby to a lymph congestion. Furthermore, the linear arrangement of the hose can lead to discomfort.

Based on the state of the art according to the DE 199 12 611 A1 The invention is based on the object to provide an easily manageable closure for a pressurizable with under or over pressure chamber, in which a cutting through the tube of the closure and thereby a lymph congestion is avoided. Furthermore, unpleasant sensations should be avoided by the required tight fit of the hose to the body or the part of the body.

The solution to this problem is based on the idea to develop the closure of the chamber such that the tube no longer linear, but in the manner of a wide belt band-shaped on the body or the part of the body comes to rest. This object is achieved in a chamber of the type mentioned above in that the closure has a pipe socket, each having a pipe opening at a front and a rear end face of the pipe socket, whose longitudinal axis extends from the front to the rear end, the pipe socket at the rear End face is gas-tightly connected to the chamber, so that the pipe opening at the rear end face of the pipe socket curses with the manhole, the rotary ring on the front end side of the pipe socket about an axis of rotation is rotatably mounted, the hose extends from the rotary ring through the interior of the pipe socket to the rear end side and the rear end of the hose is rotatably fixed along the opening edge of the pipe opening of the pipe socket at the rear end side.

The front end of the hose is non-rotatably connected to the rotary ring along the circumference. This ensures that the inner wall of the pipe socket is completely lined with the hose from the front to the rear end side.

In order not to interfere with the entry into the chamber through the manhole, the axis of rotation of the rotary ring preferably coincides with the longitudinal axis of the pipe socket.

The pressurizable with negative pressure and / or pressure chamber is in particular tubular and has at one end face on the manhole. The pipe socket is preferably arranged coaxially to the tubular chamber at the entry opening. The longitudinal axes of pipe socket and chamber and the axis of rotation of the rotary ring extend parallel to each other in this preferred embodiment of the invention. In principle, however, the chamber can have all the forms suitable for receiving the body part.

The length of the hose must be significantly greater than the length of the pipe socket, wherein depending on the length of the pipe socket, the hose length is determined such that the hose by mutually rotating the two hose ends by means of the rotating ring band-shaped on the body or the part of the body comes to the plant. Around Hoses of different lengths can be used in the closure, the hose ends are preferably detachably connected to the rotary ring or the pipe socket. In experiments it has been found that the ratio of the length of the tube to the length of the pipe socket in the range of 2: 1 to 8: 1, but preferably in the range of 2.5: 1 to 4: 1, is located. At a lower ratio, fewer turns of the rotary ring are required to close the shutter. At a ratio of 2.5: 1 (hose eg 250 mm / pipe socket 100 mm), it takes about half a turn of the turning ring to close the seal, while a ratio of 4: 1 (hose eg 400 mm / pipe socket 100 mm) is approx requires a complete revolution of the rotary ring.

The hose is made of a flexible, gas-tight material to maintain the vacuum created in the chamber. As a material, for example, a coated fabric or a plastic material into consideration.

The rotary ring of the closure is structurally preferably designed as an annular disc. The inner diameter of the annular disc corresponds approximately to the diameter of the inlet opening into the chamber. The annular disc is constructively advantageously mounted on the pipe socket in that a flange is arranged on the front end side thereof which extends radially outward from the jacket surface of the pipe socket with an outer part, the rotary ring bears against the outwardly facing side of the front flange, a releasably connected to the rotating ring locking ring engages behind the outer part of the flange with a clearance that is determined such that the rotary ring is rotatably supported relative to the front flange thereto.

Both the annular disc and the locking ring have an outer diameter which is larger than the outer diameter of the front flange. The resulting radial projections of washer and retaining ring are used for the detachable connection between the two components, in particular by means of screw. The screw connections are preferably arranged uniformly over the circumference of the flush abutting projections of annular disc and retaining ring. A structurally advantageous, easily detachable connection of the front hose end with the rotary ring is achieved in that in the rotary ring a circumferential groove is arranged, the groove opening points in the direction of the outwardly facing side of the front flange, the groove at least one releasably connected to the rotary ring Clamp completely absorbs and between each clamp and the groove bottom, the front end of the hose is fixed by the clamping piece or the clamping pieces. The clamps allow in a simple manner to change the clamping position of the front end of the hose to the rotary ring and thus the length of the hose between the rotary ring and the attachment of the rear end of the hose.

In order to releasably attach the rear end of the hose at variable clamping positions along the opening edge on the rear end side of the pipe socket, a rear flange is arranged on the pipe socket, which extends with an inner part in the direction of the longitudinal axis of the pipe socket, wherein on the inner the pipe socket facing side of the inner part of the rear flange at least one releasably connected to the flange Clamping part is arranged and between each clamping part and the inner part of the flange, the rear end of the hose is attached.

For additional protection of the front end of the hose, this edge may have a circumferential bead. The hose end is then secured not only by the clamping pieces, but also positively by the clamping piece engaging behind the bead.

In a further embodiment of the invention, elastic strips extend between the hose ends of the hose and are sewn to the hose at their longitudinal edges. The elastic strips are sewn at their longitudinal edges immediately in the stretched state of the hose. The elastic strips cause the tube to open when the closure is open, i. not mutually twisted hose ends, applies to the inner surface of the pipe socket and thereby facilitates access to the chamber.

In a further embodiment of the invention, the rotary ring is driven by a motor. To ensure the necessary personal safety when closing the motor-driven rotary ring, the drive has a torque limiter. This can be achieved, for example mechanically by a slip clutch and / or electrically by an automatic shutdown of the drive when a defined maximum current of the drive is exceeded. In addition, the drive of the rotary ring must be separable from the rotary ring by a switchable coupling in order to be able to open the rotary ring manually in the event of a power failure of the drive.

The invention will be explained in more detail with reference to the drawings. Show it:

FIG. 1

a partial perspective view of a pressurizable with vacuum chamber with frontally disposed closure,

FIG. 2

a partial section of the vacuum chamber after FIG. 1 in the area of the closure as well

FIG. 3

a view of the rotary ring of the closure from the direction of the vacuum chamber.

FIG. 1 shows partially a treatment device with an elongated, hollow cylindrical chamber (1) for receiving the lower half of the body for clarity, not shown, to be treated person. On one of the two end faces of the chamber (1) there is an access opening (2), which can be closed in a gas-tight manner by means of a closure (3) relative to the body of the person to be treated.

The on a frame (1 a) arranged chamber (1) is connected to a, not shown, controlled vacuum generator. The controlled vacuum generator generates a vacuum profile in which the pressure in the chamber (1) is lowered relative to the atmospheric pressure by, for example, a maximum of 80 mbar and alternates between the lowered pressure and the atmospheric pressure. Alternatively, the pressure in the vacuum chamber is alternated with the atmospheric pressure 35 to 80 mbar lowered and increased by 20 to 60 mbar. As a result, the negative pressure in the negative pressure chamber alternates between a first, higher negative pressure value and a second, lower negative pressure value. However, there are also applications in which the pressure in the chamber is increased from the atmospheric pressure. As a result, for example, the lymphatic flow can be improved. However, increasing the pressure above the ambient pressure may be prohibited due to pre-existing conditions, especially the cardiovascular system.

The chamber furthermore has a lying surface with a first part arranged in the vacuum chamber and a second part arranged outside the vacuum chamber in extension of the first part, on which the person to be treated lies. The lying area is for clarity in FIG. 1 not shown.

The term "gas-tight" in connection with the closure (3) in the technical sense to understand that the closure (3) seals the interior of the chamber (1) largely gas-tight compared to the ambient pressure, so that the pressure in the chamber against the atmospheric ambient pressure can be effectively lowered or increased. The closure (3) comprises a hose (4) made of a flexible largely gas-tight material, the front end of the hose (4a) is rotatably connected to a rotary ring (5). The rotary ring (5) is rotatably mounted on a front end face (6a) of a pipe socket (6) about an axis of rotation (5a). The hose (4) extends from the rotary ring (5) through the interior of the pipe socket (6) to its rear end face (6b). The pipe socket (6) points at his front end face (6a) has a front pipe opening (6c) and at its rear end face (6b) has a rear pipe opening (6d). The rear end of the hose (4b) of the hose (4) is fixed against rotation along the opening edge of the rear pipe opening (6d).

It can be seen from the figures that the pipe socket (6) preferably has a circular cross section, the cross section of the pipe openings (6c, 6d) coinciding with the cross section of the manhole (2). Conceivable, however, are also fundamentally different cross-sections of the pipe socket and / or the pipe openings and the manhole (2), resulting in other cross-sections constructively higher demands on the mounting of the rotary ring (5).

The rotary ring (5) is designed in the illustrated embodiment as an annular disc. To rotatably support the rotary ring on the front end face (6a), a front flange (7) is arranged on the pipe socket (6), wherein the front flange (7) with an outer part (7a) radially from the lateral surface of the pipe socket (6) extends outwardly and with an inner part (7b) in the direction of the longitudinal axis (6e) of the pipe socket. The rotary ring (5) abuts against the outwardly facing side of the front flange (7). A locking ring (9) detachably connected to the rotary ring (5) by means of screws engages behind the outer part (7a) of the flange (7) with a clearance determined such that the rotary ring (5) moves relative to the front flange (7). rotatably mounted on this.

For rotationally fixed attachment of the front hose end (4a) on the rotary ring (5) in the rotary ring (5) a circumferential groove (10) is inserted, the groove opening facing in the direction of the outwardly facing side of the front flange (7). The groove (10) receives two over a circular arc of 180 degrees each extending, annular clamping pieces (11). The clamping pieces (11) are fixed by means of screws (8) in the groove by means of screw openings which extend from the front side of the rotary ring (5) in the direction of the groove bottom. Previously, the front end of the hose (4a) is inserted into the groove and fixed by the clamping pieces (11) in the groove by clamping action. The screws (8) pass through the front end of the hose (4a) in the area of the groove bottom.

At the rear end face (6b), the pipe socket (6) has a rear flange (12). The rear flange extends with an outer part (12a) radially from the outer surface of the pipe socket (6) to the outside and with an inner part (12b) in the direction of the longitudinal axis (6e) of the pipe socket (6). On the inside of the pipe socket (6) facing side of the inner part (12b) of the rear flange (12) also two clamping parts (13) are detachably arranged. Between the two clamping parts (13) and the inner part of the flange (12), the rear end of the hose (4b) is fixed by the clamping action of the clamping parts (13). Screws (8) pass through the rear end of the hose (4b) in the clamping area between the clamping parts (13) and the inner part (12b) of the flange (12).

As in FIG. 2 indicated, the length of the hose (4) is greater than the length of the pipe socket (6). The length is determined so that the hose when against each other Twisting of the two hose ends (4a, 4b) comes band-shaped on the trunk of the person to the plant. The band-shaped system is carried out over a length of several centimeters, which compared to the previous linear system a lymph congestion when using the vacuum chamber and discomfort are avoided. To rotate the hose ends against each other, the rotary ring (5) by means of a handle (14) is rotated (see. FIG. 1 ), whereby the front hose end (4a), which is non-rotatably connected to the rotary ring (5), opposite to the rear, rotatably fixed to the rear flange (12) fixed hose end (4b). In order to securely fix the closure (3) after the rotation ring (5) has been rotated in the closed position, a locking device can be arranged between the rotating ring (5) and the front flange (7). <B> LIST OF REFERENCES </ b> No. designation No. designation 1 chamber 12 rear flange 1a frame 12a outer part 2 manhole 12b inner part 3 shutter 13 clamping parts 4 tube 14 handle 4a front hose end 4b rear hose end 5 rotating ring 5a axis of rotation 6 pipe socket 6a front end 6b rear end face 6c front pipe opening 6d rear pipe opening 6e longitudinal axis 7 front flange 7a outer part 7b inner part 8th screw 9 circlip 10 groove 11 Clamps
