Description

[0001] Shell for an HBOT hyperbaric chamber

[0002] The invention relates to a shell and a HBOT hyperbaric chamber according to the features of the independent patent claims.

[0003] HBOT hyperbaric chambers are hyperbaric chambers used to deliver hyperbaric oxygen therapy to one person. Hyperbaric Oxygen Therapy (HBOT) has been known since around 1960 and originally originated in the treatment of decompression sickness. HBOT is a medical treatment method in which individuals or patients inhale nearly 100% pure oxygen for medically defined periods of time, using controlled overpressure throughout the body.

[0004] By combining nearly 100% pure oxygen with the simultaneous application of positive pressure, it is possible to achieve partial oxygen pressures (pO2; "oxygen dosages") in the blood and tissues of a person that would not be achievable using pure oxygen alone or positive pressure alone. These high partial oxygen pressures (pO2) have a wide range of direct and indirect effects on the human body. Many of these effects are helpful for alleviating or curing illnesses, and for selected conditions (such as smoker's leg), they are practically the only treatment method.

[0005] In practice, it has been shown that the beneficial effect of the therapy only occurs at an internal chamber pressure of more than 1 bar overpressure, particularly between 1.3 and 2 bar overpressure. A fundamental distinction must therefore be made between HBOT hyperbaric chambers, which can have an operating pressure of approximately 1.3 to approximately 2 bar above ambient pressure, and conventional oxygen therapy devices, which have a lower overpressure of less than 1 bar, particularly between 0.3 and 0.5 bar.

[0006] HBOT hyperbaric chambers and oxygen therapy devices are known and published in various designs. For example, hyperbaric chambers are known that are constructed similarly to a steel pressure tank, with a cylindrical space for several people sealed on both sides by flanged connections with cover caps. Such chambers are generally very bulky and heavy, which severely limits their transportability and the choice of a possible installation location. Furthermore, in practice, the problem arises that the people in the chamber experience a negative subjective experience, such as claustrophobia, if they have to spend several minutes in a closed steel tank.

[0007] As an alternative to such steel tank-like devices for several people, smaller tubes are known in which a person is positioned lying down. These smaller chambers offer improved transportability, but the person's sense of space is further impaired due to the narrowness of the space, which in turn can lead to claustrophobia, for example. For this reason, viewing windows are installed in smaller tubes so that the person has at least a limited view of the outside. Especially for people with limited mobility, it is often impossible to enter such a tube lying down. Furthermore, a lying position for the person during therapy is often medically undesirable.

[0008] Although simple oxygen therapy devices with an operating pressure of less than 1 bar overpressure may potentially achieve improved transportability and also an improved sense of space, hyperbaric oxygen therapy within the meaning of the invention cannot be carried out with such devices.

[0009] The object of the invention is to overcome the disadvantages of the prior art.

[0010] In particular, it is an object of the invention to provide an HBOT hyperbaric oxygen therapy chamber with an operating pressure of 1.3 to 2 bar overpressure, without, however, having to accept the limitations of the prior art.

[0011] For example, the HBOT hyperbaric chamber should be easy to transport, allowing it to be used in conventional buildings. Furthermore, it should allow for easy entry and exit for a person with limited mobility. Furthermore, the person should have a sufficiently comfortable feeling of space during therapy. This conflict of objectives is resolved by the features of the independent patent claims.

[0012] The invention relates in particular to a shell for forming a pressurized part of an HBOT hyperbaric chamber, i.e. an HBOT hyperbaric chamber (2) for carrying out hyperbaric oxygen therapy for a person, with an operating pressure of 1.3 to 2 bar overpressure.

[0013] Preferably, a shell-shaped support grid is provided.

[0014] The support grid preferably has a plurality of support bands running along the shell shape and a plurality of openings maintained free between the support bands. A transparent window shell is preferably provided, which is held on its outer side by the support grid and covers the openings of the support grid, in particular all openings of the support grid, in a pressure-tight manner.

[0015] Preferably, the window shell is designed as a continuous shell-shaped window shell.

[0016] Preferably, the window shell is adapted to the shape of the supporting grid and runs along the shell shape of the supporting grid.

[0017] If necessary, it is provided that the window shell is supported on its outer side along the support straps on the support grille against a compressive force acting on the inner side of the window shell.

[0018] If necessary, a functional ring is provided on the edge of the shell, to which the edge of the supporting grid engages.

[0019] If necessary, the window shell and the supporting grille may protrude from the functional ring on one side.

[0020] It is preferably provided that a shell interior is kept free inside the shell-shaped assembly consisting of functional ring, window shell and supporting grid.

[0021] If appropriate, the shell interior in the area of ​​the functional ring is provided with a free interior space of at least 110 x 110 cm, preferably 130 x 130 cm. In this case, this dimension is defined as a square enclosed within the shell interior.

[0022] Optionally, it is provided that the shell interior in the area of ​​the functional ring has a free inner diameter of at least 160 cm, preferably 180 cm. Optionally, it is provided that the shell has an outer contour in at least one direction that is smaller than a rectangle with dimensions of 80 cm x 200 cm.

[0023] Where appropriate, the tray is designed to fit through a rectangular opening measuring 80 cm x 200 cm.

[0024] If necessary, the supporting straps of the supporting grid are designed to run in a basket-like manner.

[0025] If necessary, the supporting straps of the supporting grid are designed to run in a star shape.

[0026] Where appropriate, the supporting straps of the supporting grid are intended to run along symmetry planes of the shell shape.

[0027] Where appropriate, the shell may have the shape of a body of revolution or part of a body of revolution.

[0028] A sealing arrangement is provided where necessary. The sealing arrangement is provided, in particular, on the functional ring.

[0029] If necessary, it is provided that the window shell, the support grille, the functional ring and the sealing arrangement together form a composite that supports the overpressure of the HBOT overpressure chamber.

[0030] Where appropriate, the window shell is provided to be a shell-shaped composite pane.

[0031] Optionally, it is provided that it is designed as a door for an HBOT hyperbaric chamber. In particular, the invention relates to an HBOT hyperbaric chamber with an operating pressure of 1.3 to 2 bar overpressure, wherein a pressure-loaded part is designed as a shell as described.

[0032] If necessary, an overpressure source, such as a compressor, is provided to generate an operating pressure of the HBOT overpressure chamber of 1.3 to 2 bar overpressure. In particular, an overpressure source, such as a compressor, is provided to generate an operating pressure of the HBOT overpressure chamber of 1.3 to 2 bar overpressure.

[0033] If necessary, a seat arranged or arrangeable within the HBOT hyperbaric chamber is provided for the seating positioning of a person within the HBOT hyperbaric chamber.

[0034] Optionally, an oxygen source, an oxygen dispensing device, such as in particular an oxygen mask, and an oxygen line conducting oxygen from the oxygen source to the oxygen dispensing device are provided.

[0035] If necessary, the oxygen source is located outside the HBOT hyperbaric chamber.

[0036] The oxygen source may include or be an oxygen concentrator that extracts oxygen from the ambient air. The oxygen source may be an existing local oxygen source, such as a hospital oxygen supply. The oxygen source may be an oxygen cylinder.

[0037] If appropriate, it is provided that the oxygen dispensing device, in particular the oxygen mask, is arranged within the HBOT hyperbaric chamber.

[0038] If appropriate, the oxygen line runs from the oxygen source through the shell, in particular through the shell's functional ring, and further to the oxygen dispensing device. If appropriate, the oxygen source and the oxygen line deliver the oxygen within the HBOT hyperbaric chamber exclusively via the oxygen dispensing device and preferably directly to the mouth and / or nose of the person in the HBOT hyperbaric chamber.

[0039] Where appropriate, the HBOT hyperbaric chamber and shell shall be designed to withstand a test pressure of at least 2.86 bar gauge and / or be capable of withstanding a test pressure of at least 2.86 bar gauge.

[0040] If necessary, a base module is provided to which the shell is movably attached.

[0041] If necessary, two shells are provided, whereby the two shells, in particular their functional rings, are sealingly connected to each other to form the HBOT overpressure chamber.

[0042] The present design overcomes the disadvantages of conventional single-place HBOT chambers and enables access to and use of the HBOT chamber especially for people with limited mobility or injuries.

[0043] The shell and / or the HBOT hyperbaric chamber preferably have the following features and advantages:

[0044] - Weight reduction of the HBOT hyperbaric chamber by using two plastic half-shells that together form the window shells. Optionally, the window shell also includes a film, forming a composite pane.

[0045] - Pressure distribution on the 2 half shells by thin (designated) support straps made of a solid material such as metal.

[0046] - Lightweight construction of the HBOT chamber in modules; maximum 500 kg, preferably maximum 350 kg total weight.

[0047] - Comfortable entry via a tray opening. This is advantageous or necessary for injured or mobility-impaired patients. - Movable seat for safe patient entry and exit from the chamber.

[0048] - Transparent construction to avoid claustrophobia in the HBOT chamber.

[0049] - Transparent construction for safe visual monitoring of the person in the chamber.

[0050] - Orthopaedic function of the seat for individual patient adjustment

[0051] To ensure easy and safe transfer of the patient, for example, from a hospital chair to the chamber seat, the seat can be moved outside the chamber, preferably using a sliding or swivel system, into a position optimized for the patient. The mechanism can be anchored in the end positions using force packs (spring packs) to relieve the load on the drive if necessary. This allows for the use of lightweight and compact drives. The position / tilt of the chair can be adjusted via a control console, if necessary.

[0052] The seat is preferably designed to be pivoting and offers the possibility of moving it into a comfortable position in order to ideally meet the needs of the patient.

[0053] In order to be able to load the HBOT overpressure chamber with 1.3 to 2 bar overpressure, the shell is preferably locked multiple times along the functional ring in a pressure-tight manner. The locks are preferably distributed along the functional ring. The support straps preferably engage in those areas of the functional ring where the locks are also provided. The support straps therefore preferably engage in the areas of the locks.

[0054] The HBOT hyperbaric chamber is pressurized to a defined overpressure via a pressure source, preferably one installed externally. In all embodiments, the HBOT hyperbaric chamber is preferably pressurized with normal (ambient) air.

[0055] The HBOT hyperbaric chamber may be equipped with ventilation. The ventilation flow rate can be, for example, 50–100 liters per minute, preferably approximately 80 liters per minute. Ventilation can be provided by the positive pressure source. With this ventilation rate of 80 l / min, a total air volume of 1800 liters at 1.5 bar and 2400 liters at 2 bar, and a human body volume of approximately 100 liters, changes in the air composition within the chamber are insignificant.

[0056] The overpressure source preferably comprises a compressor. This can have two sets of air filters, for example, 0.05 and 0.01 micrometers. For example, the compressor can have a flow rate of 100 l / min.

[0057] The oxygen mask in the chamber is supplied with oxygen via an oxygen source, preferably located externally. Depending on the required chamber pressure, one or two oxygen sources are operated in parallel.

[0058] Since the patient generates approximately 100W of heat in a resting position, an air conditioning module is preferably provided outside the chamber to cool the air in the chamber.

[0059] In all embodiments, it is preferably provided that the HBOT hyperbaric chamber is approved as a medical device. It is preferably provided that the HBOT hyperbaric chamber withstands a test pressure of at least 2.86 bar overpressure or is designed for a test pressure of at least 2.86 bar overpressure.

[0060] The support grid or its support straps can be formed from a flat, shell-shaped semi-finished product, such as a plate, particularly a thin metal plate. The openings of the support grid are preferably formed by recesses in the support material or plate. If necessary, a steel plate can be provided with the openings. Subsequently, the shell shape of the support grid can be created in a cavity by deep drawing or pressing.

[0061] If necessary, the supporting grid must be made of a tensile-resistant material, such as steel or another metal alloy. Examples of suitable metals or metal alloys include: stainless steel, chrome-nickel steel, preferably S700MC (according to DIN EN 10149-2), hardened structural steel, or aluminum alloy.

[0062] If necessary, the supporting grid is made of a fiber composite material such as GRP or CFRP, with the shell-shaped configuration being created by inserting fibers or fiber mats into a shell-shaped mold and then curing them. The openings can be left out during the insertion process.

[0063] The window shell can, if necessary, be formed from a flat semi-finished product, a plate, or a pane that is curved into a shell shape. For example, the window shell can be made from a transparent plastic such as PMMA, acrylic glass, and / or polycarbonate.

[0064] The invention will be further described below with reference to the figures.

[0065] Fig. 1 shows a schematic oblique view of a possible embodiment of a HBOT hyperbaric chamber with two shells.

[0066] Fig. 2 shows the device from Fig. 1 , but in an open position.

[0067] Fig. 3 shows a schematic sectional view of an HBOT hyperbaric chamber.

[0068] Fig. 4 shows a schematic sectional view of details of a shell.

[0069] Unless otherwise stated, the reference numerals correspond to the following components: shell 1, HBOT hyperbaric chamber 2, support grid 3, support strap 4, opening 5, window shell 6, functional ring 7, shell interior 8, hyperbaric source 9, seat 10, oxygen source 11, oxygen dispensing device 12, oxygen line 13, base module 14, sealing assembly 15, square 16.

[0070] Fig. 1 shows a schematic oblique view of a possible embodiment of an HBOT hyperbaric chamber 2 with two shells 1. In particular, two shells 1 are provided, which, when assembled, form or at least delimit an HBOT hyperbaric chamber 2. The shell 1 comprises a support grid 3. This support grid 3 comprises several support straps 4. In particular, the support grid 3 is composed of several support straps 4. The support straps 4 and, in particular, the entire support grid 3 have a shell-like shape.

[0071] Several openings 5 ​​are kept free between the carrying straps 4. These openings 5 ​​allow the person to view the surroundings from the chamber. To ensure that overpressure can still be built up in the HBOT hyperbaric chamber 2, these openings 5 ​​are sealed by a window shell 6. The window shell 6 is preferably transparent.

[0072] Preferably, a single window shell 6 is provided for each shell 1, which closes all openings 5 ​​of the support grid 3. The window shell 6 can, for example, be formed as a single piece. However, if necessary, the window shell 6 can also be formed in multiple parts. Preferably, one window shell 6 is provided for each shell 1.

[0073] The shell 1 comprises a functional ring 7. The functional ring 7 is preferably a closed, ring-shaped body. The edge of the support grid 3 engages this functional ring 7. In particular, the support straps 4 run along a shell-like shape that extends away from the functional ring 7 on one side.

[0074] In the present embodiment, two shells 1 are provided, each comprising a functional ring 7. In the closed position shown in Fig. 1, the two functional rings 7 are pressed against each other and sealed against each other.

[0075] A free shell interior 8 is provided within the functional ring 7. The shell interior 8 is bounded by the shell 1 or by the shells 1.

[0076] In the present embodiment, a base module 14 is provided. This base module 14 supports the shell 1.

[0077] To increase the pressure in the shell interior 8, an overpressure source 9 is provided. This overpressure source 9 can, for example, be a compressor. If necessary, the overpressure source 9 can be provided within the base module 14. According to a preferred embodiment, however, the overpressure source 9 can also be arranged away from the HBOT overpressure chamber 2, so that any noise emissions emanating from the overpressure source 9 cannot be perceived as disturbing by the person being treated. Preferably, a line is provided that connects the overpressure source 9 to the shell interior 8 in order to increase the pressure in the shell interior 8, and in particular to increase it to 1.3 - 2 bar overpressure.

[0078] In the position shown in Fig. 1, a seat 10 is arranged in the shell interior 8. This seat 10 is, for example, an adjustable seat that allows a person to be positioned in a sitting or reclining position.

[0079] Additionally, the HBOT hyperbaric chamber 2 includes an oxygen source 11. The oxygen source 11 is configured to supply essentially pure oxygen to the subject. For this purpose, an oxygen dispensing device 12 and an oxygen line 13 are provided, which, however, are not visible in the illustration in Fig. 1.

[0080] A sealing arrangement 15 is provided to seal the HBOT hyperbaric chamber 2. The sealing arrangement 15 seals the components of the shell 1, such as the functional ring 7, window shell 6, and support grid 3, from one another. Furthermore, the sealing arrangement 15 also seals the shell 1 from other parts of the HBOT hyperbaric chamber 2.

[0081] Fig. 2 shows the HBOT hyperbaric chamber 2 of Fig. 1, but in a different position. In this position, the HBOT hyperbaric chamber 2 is open. In particular, the two shells 1 are arranged away from each other so that it is easy for the person to get in. In the present position, the seat 10 is displaced so that it is even easier for a person to get in. The seat 10 can be moved between the two shells 1 to close the HBOT hyperbaric chamber 2. The shells 1 are then closed, as shown in Fig. 1. The components of Fig. 2 correspond to those components that were also shown and described in Fig. 1.

[0082] Fig. 3 shows a sectional view of a possible embodiment of an HBOT hyperbaric chamber 2. This can, for example, be designed the same as described in Figs. 1 and 2. The HBOT hyperbaric chamber 2 comprises a shell 1. The shell 1 is a pressurized part of the HBOT hyperbaric chamber 2. The shell 1 comprises a supporting grid 3 composed of several supporting straps 4. Openings 5 ​​are provided or kept free between the supporting straps 4. The openings 5 ​​are closed by a window shell 6.

[0083] A functional ring 7 is provided on the edge of the shell 1, and the edge of the support grid 3 engages this functional ring 7. A shell interior 8 is kept free within the functional ring 7. This shell interior 8 serves to accommodate the person during therapy. In all embodiments, the shell interior 8 is preferably dimensioned such that a person can be positioned in a seated position within the HBOT hyperbaric chamber 2. In particular, a free space of at least 110 x 110 cm, preferably approximately 130 x 130 cm, should be kept free. These dimensions are sufficient to provide a person with sufficient space while seated. In the present case, this dimension is defined as a square 16 enclosed within the shell interior.

[0084] In the present embodiment, the shell interior 8 is substantially round and has an inner diameter of at least approximately 160 cm, preferably approximately 180 cm.

[0085] In principle, it would be desirable to make the chamber as large as possible to provide a comfortable feeling of space for the person. However, this is not possible due to technical limitations such as pressure resistance or transportability. The dimensions of the shell 1 should therefore preferably be designed such that it fits through a rectangular opening 5 with dimensions of 80 cm x 200 cm. The outer diameter of the shell 1 is therefore preferably less than or equal to 200 cm. The HBOT hyperbaric chamber 2 comprises an oxygen source 11. The oxygen source 11 is designed to supply the person with oxygen, in particular essentially pure oxygen. For this purpose, the oxygen source 11 is connected to an oxygen dispensing device 12 via an oxygen line 13. The oxygen dispensing device 12 is preferably an oxygen mask.

[0086] In all embodiments, it is preferably provided that the oxygen dispensing device 12 is an oxygen mask that can be sealingly connected to the person's mouth and / or nose. The oxygen line 13 extends essentially closed to the oxygen dispensing device 12 through the shell interior 8 of the HBOT hyperbaric chamber 2. This can prevent highly concentrated oxygen from entering the shell interior 8 of the HBOT hyperbaric chamber 2. The oxygen line 13 is preferably routed through the functional ring 7 of the shell 1. The sealing arrangement 15 seals the passage of the oxygen line 13.

[0087] The person is preferably seated within the HBOT hyperbaric chamber 2. For this purpose, the device comprises a seat 10. The seat 10 can, for example, be supported on the base module 14 and extend with a seat base through the shell 1 or the connecting area between the shells 1. This area can also be sealed by the sealing arrangement 15.

[0088] Fig. 4 shows a schematic sectional view of a tray 1. The tray 1 can be used, for example, in the devices according to Fig. 1, 2, and / or 3. The tray 1 is a pressurized part of an HBOT hyperbaric chamber 2. The tray 1 comprises a support grid 3 composed of several support belts 4. The sectional view runs directly through a support belt 4, so the openings 5 ​​provided between the support belts 4 are not visible.

[0089] The shell 1 comprises a window shell 6. The window shell 6 is supported from the outside by the support grid 3 against the compressive forces acting in the shell interior 8. In particular, the window shell 6 rests against the support grid 3 from the inside. The support grid 3 thus supports the window shell 6 along the course of the support straps 4. The support straps 4 preferably rest on the outside of the window shell 6 along their course.

[0090] This design allows the person to have a good view of the outside despite the high pressure forces inside the HBOT hyperbaric chamber 2. The functional ring 7 is provided to further improve stability and also to allow for the passage of any cables. The functional ring 7 is a load-bearing element that defines a free shell interior 8. The support grid 3 and the window shell 6 extend in a shell-like manner on one side from the functional ring 7. A sealing arrangement 15 serves to seal the shell 1 from other components of the HBOT hyperbaric chamber 2.

[0091] To improve transportability, the tray 1 preferably has an outer contour, at least in one direction, that is smaller than a rectangle with dimensions of 80 cm x 200 cm. This rectangle is shown in the drawing with dashed lines. This dimension allows the tray 1 to be transported through a standard door.
