Description

Device comprising a pressure chamber and a pump

[0001] The present invention relates to a device with a pressure chamber and a pump, in particular for carrying out an alternating pressure massage on a user.

[0002] DE 199 12 61 1 A1 describes a vacuum chamber with which a human body can be treated. The vacuum chamber stands on the floor and has an entry opening at the top. A tube made of a largely flexible material is attached to the entry opening. The tube can be pulled over the torso like a skirt from clothing and then twisted by turning. Twisting the tube causes the fabric to wrap tightly around the torso, particularly the abdomen. The twisted tube creates an airtight seal around the vacuum chamber. During operation, the pressure in the vacuum chamber can be reduced in order to treat the human body.

[0003] A particular disadvantage is that this type of seal only works when the vacuum chamber is upright and the access opening is facing upwards. In this case, entry into the vacuum chamber must be from above. Firstly, entry into the upright vacuum chamber is very uncomfortable, as a user has to raise their legs very high in order to enter the vacuum chamber. Particularly within the narrow dimensions of the vacuum chamber, it is not possible to provide an entry aid in the form of a stool or similar, on which the user can support themselves and which can be easily led out again between the chamber wall and the user after entry. Furthermore, a seal on the torso or abdomen of the user in a version of the upright vacuum chamber can only be used in certain Size dimensions of the users are realized, i.e. a very tall user and a very short user cannot use the same vacuum chamber.

[0004] In contrast, the present invention is based on the object of creating an improved device for treating the human body, which can be used regardless of the body size of the user.

[0005] This object is achieved by a device according to claim 1. Embodiments of the invention are specified in the dependent claims. Advantageous further developments will become apparent from the description and the exemplary embodiments.

[0006] A device according to the invention comprises a pressure chamber and a pump. The pressure chamber has a closure means which can be converted from an open to a closed state and vice versa. The closure means is designed to hermetically seal the pressure chamber around a human body arranged on the lying surface from the environment when closed. The pump is designed to pump a gas into the pressure chamber and thus increase a pressure within the pressure chamber and to pump it out of the pressure chamber and thus reduce a pressure within the pressure chamber. Furthermore, a lying surface is included, wherein a first part of the lying surface is arranged in the pressure chamber and wherein a second part of the lying surface is arranged outside the pressure chamber.

[0007] The device according to the invention has many advantages. A significant advantage of the device is that a user can lie down on the lying surface, allowing the legs and lower body to be They can be comfortably inserted into the pressure chamber, which extends essentially horizontally for this purpose. Furthermore, the dimensions of the pressure chamber can be adjusted to the user's maximum body size. The user can then position themselves on the couch, regardless of their body size, so that the closure device can seal the torso, and especially the abdomen. This advantageously provides a device that enables cosmetic treatment or therapy regardless of the user's body size.

[0008] The device enables an improvement in physical appearance, especially the complexion. The pump creates an (alternating pressure) massage by applying negative and / or positive pressure to the lower body. Furthermore, the application can stimulate lymph flow and have a positive effect on connective tissue.

[0009] The pressure chamber has a closure means which, when closed, is designed to hermetically seal the pressure chamber around a human body arranged on the lying surface from the environment. The term “hermetically sealed” is understood in particular to mean that the pump can achieve and maintain a negative or positive pressure within the pressure chamber of more than 30 mbar. A negative pressure of up to -130 mbar is advantageously possible. The pump is designed to pump a gas into the pressure chamber or out of the pressure chamber. In the context of this description, a gas is understood in particular to mean a gas mixture, such as (ambient) air. The gas is preferably air.

[0010] The pump preferably comprises at least one side channel compressor. The side channel compressor can advantageously achieve the required pressure level within the pressure chamber. Other pumps are also possible.

[0011] The pressure chamber preferably includes LED strips on its exterior. The use of at least one LED strip advantageously provides visual feedback to the user and operating personnel regarding the operating status of the pressure chamber. For this purpose, the LED strip can, for example, periodically turn on and off (pulse) during the massage application to indicate massage operation, while at the end of the application, the LED strip, for example, remains continuously lit. Color codes can also be used to clarify the current operating status (e.g., red: not available or in operation, green: available and usable).

[0012] The pressure vessel or pressure chamber is preferably made of carbon and is therefore particularly light and robust.

[0013] Preferably, the pressure chamber designed as a pressure vessel is movable from a first state to a second state and vice versa, in particular along a substantially horizontal direction. The pressure vessel or pressure chamber is movable manually or electrically for comfortable positioning of the user and is thus particularly suitable for people with disabilities. In the first state of the pressure chamber, in particular the first part of the lying surface is arranged for more than three-quarters of its length, preferably completely, within the pressure chamber. In the second state of the pressure chamber, in particular the first part of the lying surface is arranged for less than half of its length outside the pressure chamber (also called the pulled-out state). Advantageously, a method provides a particularly comfortable Access and use of the device is made possible by allowing the user to position themselves comfortably on the lying surface and then being retracted into the pressure chamber along with the lying surface. This makes the device particularly comfortable to use for people with limited mobility.

[0014] Particularly preferably, the pressure vessel is movable relative to a base frame via a rail construction. This can be done manually or electrically via an actuator. The two lying surfaces are attached, in particular permanently, to the base frame. Advantageously, this does not change the user's orientation in relation to the base frame when getting in and out of the device. The user's center of gravity is therefore always within the base frame (with proper use). This minimizes or, in particular, completely prevents the device from tipping over when getting in and out of the pressure chamber and, above all, when lying down on the lying surface.

[0015] In particular, the angle of the second part of the lying surface relative to the first part is adjustable. Advantageously, the second part of the lying surface can be angled relative to the first part so that the user can use the second part of the lying surface as a backrest. This allows the user to initially sit down with the second lying surface angled, similar to a seat, and then move the second lying surface into a lying position with the user's upper body. Furthermore, the desired angle of the second lying surface can also be adjusted during treatment if this is perceived as comfortable.

[0016] Preferably, the first and second lying surfaces are height-adjustable, preferably together or individually. This advantageously allows the height of the lying surface to be optimized for the user, allowing them to easily step onto it. Furthermore, it is also possible to adjust the height of the lying surface to optimize the sealing effect of the closure element by aligning a body axis in height relative to the closure element.

[0017] Preferably, the first and second lying surfaces touch each other. Preferably, the first and second lying surfaces are firmly connected to each other. Preferably, the first and second lying surfaces touch each other permanently. Advantageously, there is a continuous lying surface.

In particular, the closure ring is mounted on the pressure chamber by a bearing. Preferably, the bearing comprises a plurality of ball bearings so that the closure ring can rotate particularly smoothly. In particular, the closure ring is made of aluminum and is therefore particularly lightweight. Preferably, the closure means comprises a flexible material mechanism made of an airtight or gas-tight material, which is in particular tubular. In particular The flexible hose wraps itself around the user's torso by twisting or twirling it, creating an airtight seal.

[0019] The fabric mechanism advantageously has a contact length of a contact surface of between 2 and 20 cm, preferably between 4 and 15 cm and particularly preferably between 6 cm and 10 cm. In an advantageous embodiment, the fabric mechanism has a contact length of approximately 8 cm (+- 20%). In particular, the contact length can also be more than 25 cm, 30 cm or even 40 cm. Here, the contact surface is the area that is available to rest on the user's torso. Advantageously, the long contact length compared to prior art systems with a contact length of 0.5 cm to 1 cm enables the user's torso to be particularly well sealed against the environment. In addition, the pressure acting on the torso is low due to the large contact surface, so that the fabric mechanism is not perceived as "cutting".This makes it possible to use the device to achieve negative pressures and positive pressures of up to +-130 mbar in the pressure chamber during operation.

[0020] Advantageously, the lying surface is at least partially curved transversely to the direction of travel of the bed. This allows the closure element to form an even better seal with the airtight fabric mechanism, especially at the sides of the lying surface.

[0021] In particular, the inclination of the lying surface can be adjusted so that, for example, the user's feet are raised above their torso. Such a negative angle can advantageously be 5°, 10°, or 20° or more. During operation of the device, lymphatic return, particularly from the user's legs, is advantageously pre-loaded. This advantageously further improves the effectiveness of the treatment.

[0022] Preferably, the locking ring has a plurality of recesses along its circumference, wherein the locking means comprises a fixing bolt, and wherein the fixing bolt is designed to prevent rotation of the locking ring when arranged in one of the recesses, also called a quick-locking mechanism.

[0023] In particular, a recess has a round, especially circular, cross-section. Advantageously, the fixing bolt has a tapered section; in particular, the fixing bolt is designed as a truncated cone, which preferably tapers conically along a central axis. The fixing bolt is expediently displaceable parallel to a central axis of the locking ring and insertable into the recess. In particular, a displacement leads to a locking or securing of the locking ring or a release of the locking ring.

[0024] Preferably, the closure means comprises a rocker mechanism. In particular, the fixing bolt can be guided out of the recess by actuating the rocker mechanism. Preferably, the rocker mechanism comprises a rocker or a pull lever, which is designed as a two-sided lever. Preferably, the fixing bolt is fastened to the rocker. In particular, the rocker is rotatably received at a fulcrum on the pressure chamber or the vacuum container. In particular, the rocker mechanism comprises a spring unit, which preloads the fixing bolt, in particular into a closed position, so that the rocker mechanism is automatically preloaded into a locking position. Preferably, the spring unit comprises a spiral spring or the like. Advantageously, the The rocking mechanism can thus be operated with one hand. In particular, the rocking mechanism comprises a mounting flange through which it is held in place in the pressure chamber. The mounting flange preferably has an opening through which the fixing bolt can be passed.

[0025] In particular, the device comprises a control means configured to control the pump. In particular, the control means enables the implementation of an alternating pressure program, which is configured in particular as a massage program, and in particular other functions, such as changing the inclination of the second lying surface or moving the pressure chamber. Advantageously, the control means comprises an operating unit, which is configured in particular as a tablet. The operating means can preferably be connected wirelessly, e.g., via a radio connection via Wi-Fi, Bluetooth, or the like.

[0026] The control means preferably comprises a measuring unit with at least one pressure sensor for monitoring the pressure in the pressure chamber. The pressure sensor is advantageously designed as a pressure transmitter. In particular, the measuring unit can comprise further sensors, in particular for recording user data, such as height, circumference, weight, or the like. The data recorded by the measuring unit can advantageously be taken into account during use in order to adapt and adjust the application to the user. Furthermore, the position of the pressure vessel can be monitored by the measuring unit during use. The position can be monitored technically using limit switches and / or overrun switches.

[0027] Preferably, the device comprises a second actuator which is designed to actuate the pressure vessel The pressure chamber is moved parallel to the lying surface from the first state to the second state and vice versa. In particular, the control means is designed to control the second actuator. In one embodiment, the pressure vessel can also be moved manually.

[0028] In particular, the control means is designed to create a control program for the pump. Advantageously, the control means is designed to control the pump according to the control program, and wherein the control means is designed to use a plurality of user parameters when creating the control program. In particular, the user parameters include values ​​such as age, gender, weight, height, lifestyle habits such as smoker characteristics, exercise, and sporting activity.

A change in pressure can advantageously create a massage effect, which has a particularly positive effect on the skin's appearance.

[0035] The device 29 further comprises a base frame 32 on which the lying surface 3, 4 and the pressure chamber 1 are arranged. The pressure chamber 1 can be moved relative to the lying surface 3, 4 and the base frame 32 via a rail construction 18. This allows a user to first position themselves comfortably on the lying surface 3, 4 and lie down, and then the pressure chamber 1 can be moved from the first or retracted state 30 shown here to the extended state 31. This movement is carried out either manually or via a second actuator 14, which is designed here as an electric drive and can be controlled via a control means 7. In the first state 30, the first lying surface 3 is arranged completely within the pressure chamber 1, and in the second extended state 31, less than half of its length is arranged outside the pressure chamber 1.

[0054] During the procedure, the operator is preferably protected by overflow switches. During application, the pressure can be monitored using a pressure transmitter.

[0055] The application of alternating pressure massage, in particular, primarily serves to improve the appearance of the skin. A beneficial side effect of this massage can be the stimulation of lymph flow and the positive effect on the connective tissue of the lower body. The pressure vessel 1a is sealed, in particular, by means of an airtight fabric, in particular a material 8, for example, similar to the airbag material known from the automotive industry.

[0056] The core of the control device 7, in particular the control system, is the software based on real measurements and / or user parameters requested by the user, which designs the most advantageous and, if necessary, best possible application for each user at the time of the measurement. Preferably, a basic program based on customer-specific parameters, such as age, gender, weight, height, and lifestyle habits, is stored in the control device's memory. This basic program can then be replaced or refined with current daily measurements if necessary. Thus, each individual application can be unique based on the user's basic program and daily condition. i.e. preferably individually adapted to the user's current appearance.
