Description

Technical Field

[0001] This invention relates to the field of pressurized chamber technology, and more particularly to a pressurized chamber that can be folded and stored. Background Technology

[0002] A soft air pressurization chamber is a medical device that creates a high-pressure environment by pressurizing air. This environment can be used to treat decompression sickness and for hyperbaric oxygen therapy. Inside the chamber, the human body is in a high-pressure environment. This environment increases the partial pressure of oxygen in the body, significantly increasing the amount of oxygen dissolved in body fluids and the effective diffusion radius of oxygen. Therefore, a soft air pressurization chamber can overcome hypoxia and prevent its occurrence and development. In conclusion, a soft air pressurization chamber is an effective medical device that can be used to treat decompression sickness and alleviate discomfort symptoms caused by altitude sickness.

[0003] Currently, during use, the high pressure of soft pressurized chambers can easily cause uneven stress at the joints near the zipper, resulting in radial deformation of the chamber and reducing its pressure resistance. Summary of the Invention

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problem that uneven stress at the connection near the zipper causes radial deformation of the capsule, which reduces the pressure resistance of the capsule, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a pressurized chamber that can be folded and stored.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a foldable pressurized chamber, comprising a chamber assembly including a foldable chamber and a pressure-bearing mesh cover disposed on the outer wall of the foldable chamber, wherein the side wall of the foldable chamber is provided with a double-sided zipper and the side wall of the pressure-bearing mesh cover is provided with a tensioning member.

[0008] The oxygen supply assembly includes an observation window disposed on the side wall of the folding cabin, an oxygen supply port disposed on the outer wall of the folding cabin, and an oxygen exhaust port on the side wall of the oxygen supply port.

[0009] As a preferred embodiment of the foldable pressurized chamber body of the present invention, the tensioning member includes a fixing strap disposed on the inner wall of the pressure-bearing mesh cover, a movable strap is installed at one end of the fixing strap, and a connecting block is installed at one end of the movable strap.

[0010] As a preferred embodiment of the foldable pressurized chamber body of the present invention, the tensioning member further includes a connecting rod disposed at the end of the connecting block, and the connecting blocks are evenly arranged in six groups along the length direction of the foldable chamber body, and the connecting rod is used to connect the six groups of the connecting blocks.

[0011] As a preferred embodiment of the foldable pressurized chamber body of the present invention, the tensioning member further includes a limiting arc plate disposed on the inner wall of the connecting rod, the side wall of the limiting arc plate is provided with an ejector block, the end of the limiting arc plate is installed with a connecting strap, and a magnetic plate is installed inside the connecting strap.

[0012] As a preferred embodiment of the foldable pressurized chamber body of the present invention, the ejector block includes a box body disposed on the side wall of the limiting arc plate, the box body having a sliding groove inside, and the sliding groove having a sliding rod inside.

[0013] As a preferred embodiment of the foldable pressurized chamber body of the present invention, the ejection block further includes a connecting rod disposed on the side wall of the sliding rod, a movable rod is installed on the side wall of the connecting rod, a fixed cylinder is sleeved on the side wall of the movable rod, a telescopic spring is sleeved on the side wall of the movable rod, and a limit block is installed at one end of the sliding rod.

[0014] As a preferred embodiment of the foldable pressurized chamber body of the present invention, the ejector block further includes a first groove provided on the side wall of the limiting block, a second groove provided on the side wall of the limiting block, a connecting shaft provided inside the limiting arc plate, a limiting plate installed at the end of the connecting shaft, a torsion spring sleeved on the side wall of the connecting shaft, a baffle installed on the side wall of the connecting shaft, and an anti-detachment plate installed on the side wall of the baffle.

[0015] As a preferred embodiment of the foldable pressurized chamber body described in this invention, the oxygen supply assembly further includes two reserved ports provided on the side wall of the foldable chamber body.

[0018] The beneficial effects of this invention are as follows: This invention inflates the interior of the cabin assembly by activating the oxygen supply component, thereby supplying oxygen. During the oxygen supply process, expansion occurs, which in turn expands the pressure-bearing mesh cover through the folding cabin. Then, the connecting rod droops due to its own gravity, and the metal blocks on both sides of the connecting rod attract and initially limit the magnetic plate. During the expansion process, the connecting rod moves into the interior of the limiting arc plate, thereby squeezing the ejector block and tightening the folding cabin. This effectively reduces the problem of uneven stress causing radial deformation of the capsule and reducing the cabin's pressure resistance. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0037] Example 1

[0038] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a foldable pressurized cabin body, including a double-sided zipper 103 that becomes increasingly tighter during the expansion process, which can be opened by people inside and outside. When the folded cabin body 101 expands to about 80%, its connecting rod 104d will be connected to the magnetic plate 104h vertically through the expansion and its own gravity.

[0039] Specifically, the cabin assembly 100 includes a folding cabin 101 and a pressure-bearing mesh cover 102 installed on the outer wall of the folding cabin 101. The side walls of the folding cabin 101 are equipped with double-sided zippers 103, and the top of the cabin is equipped with a double-layered high-strength sealing zipper, providing an emergency escape function. After decompression is achieved through the cabin's vent valve, the patient can open the sealing zipper to escape. The side walls of the pressure-bearing mesh cover 102 are equipped with tensioning members 104.

[0040] Furthermore, the tensioning member 104 includes a fixing strap 104a disposed on the inner wall of the pressure-bearing mesh cover 102, a movable strap 104b installed at one end of the fixing strap 104a, and a connecting block 104c installed at one end of the movable strap 104b.

[0041] Furthermore, the tensioning member 104 also includes a connecting rod 104d disposed at the end of the connecting block 104c, wherein the connecting rod 104d and the connecting block 104c are arranged in a U-shape, and six sets of connecting blocks 104c are evenly arranged along the length direction of the folding cabin 101, and the connecting rod 104d is used to connect the six sets of connecting blocks 104c.

[0042] Furthermore, the tensioning member 104 also includes a limiting arc plate 104e disposed on the inner wall of the connecting rod 104d, a push-out block 104f disposed on the side wall of the limiting arc plate 104e, a connecting strap 104g installed at the end of the limiting arc plate 104e, and a magnetic plate 104h installed inside the connecting strap 104g.

[0043] Operation process: Oxygen is supplied to the interior of the folding chamber 101 through the oxygen supply port 202 in the oxygen supply component 200. The expansion generated when the folding chamber 101 is filled causes the pressure-bearing mesh cover 102 to expand as well. During the expansion process, the expansion force and the gravity of the connecting rod 104d can effectively attract the magnetic plate 104h. When the folding chamber 101 expands to 80%, the subsequent expansion force drives the connecting rod 104d to move into the interior of the limiting arc plate 104e, and then squeezes the ejector block 104f, causing the ejector block 104f to slide in the sliding groove 104f-2 into the interior of the box 104f-1. This eliminates the need to connect and fix the connecting rods 104d to the limiting arc plate 104e one by one, thereby improving the connection efficiency.

[0044] Example 2

[0045] Reference Figures 5-10 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the ejector block 104f includes a box body 104f-1 disposed on the side wall of the limiting arc plate 104e. The box body 104f-1 is provided with a sliding groove 104f-2 inside, and a sliding rod 104f-3 is provided inside the sliding groove 104f-2.

[0046] Specifically, the ejector block 104f also includes a connecting rod 104f-4 disposed on the side wall of the sliding rod 104f-3. A moving rod 104f-5 is installed on the side wall of the connecting rod 104f-4. A fixed cylinder 104f-6 is sleeved on the side wall of the moving rod 104f-5. A telescopic spring 104f-7 is sleeved on the side wall of the moving rod 104f-5. One end of the telescopic spring 104f-7 is connected to the moving rod 104f-5. The end of the telescopic spring 104f-7 away from the moving rod 104f-5 is connected to the fixed cylinder 104f-6. A limit block 104f-8 is installed on one end of the sliding rod 104f-3.

[0047] Furthermore, the ejector block 104f also includes a first groove 104f-9 provided on the side wall of the limiting block 104f-8, a second groove 104f-10 provided on the side wall of the limiting block 104f-8, a connecting shaft 104f-11 provided inside the limiting arc plate 104e, a limiting plate 104f-12 installed at the end of the connecting shaft 104f-11, a torsion spring 104f-13 sleeved on the side wall of the connecting shaft 104f-11, a baffle 104f-14 installed on the side wall of the connecting shaft 104f-11, and an anti-detachment plate 104f-15 installed on the side wall of the baffle 104f-14.

[0048] The rest of the structure is the same as in Example 1.

[0049] Operation process: Oxygen is supplied to the interior of the folding chamber 101 through the oxygen supply port 202 in the oxygen supply assembly 200. The expansion generated during the filling of the folding chamber 101 causes the pressure-bearing mesh cover 102 to expand as well. During this expansion, the expansion force and the gravity of the connecting rod 104d effectively attract the magnetic plate 104h. When the folding chamber 101 expands to 80%, the subsequent expansion force moves the connecting rod 104d to the limiting arc plate 104e. Inside, the baffle 104f-14 is squeezed, causing it to deflect and move the anti-detachment plate 104f-15. The anti-detachment plate 104f-15 then blocks the limiting arc plate 104e. The deflected baffle 104f-14 then squeezes the limiting block 104f-8, moving it into the first groove 104f-9 for limiting. The connecting rod 104d, during its movement, then uses the second groove 104f-10 to limit the movement of the limiting top. When the device is deflating, its expansion force gradually decreases. The elastic force of the telescopic spring 104f-7 effectively drives the sliding rod 104f-3 to move. The moving sliding rod 104f-3 drives the limiting block 104f-8 to move. During movement, the limiting block 104f-8 pushes out the baffle 104f-14 and the connecting rod 104d through the first groove 104f-9 and the second groove 104f-10 respectively. Because the limiting block 1... When the connecting rod 104d is ejected from the 04d-8, it is positioned on the anti-detachment plate 104d-15, thereby pressing down the baffle 104f-14 under the action of gravity. The baffle 104f-14 also blocks the limiting arc plate 104e, preventing the connecting rod 104d from moving into the interior of the limiting arc plate 104e. This effectively prevents the connecting rod 104d from completely detaching from the limiting arc plate 104e when the folding cabin 101 is venting.

[0050] Example 3

[0051] Reference Figures 1-2 This is the third embodiment of the present invention. The difference between this embodiment and the previous embodiments is that the folding cabin 101 is horizontal, cylindrical, with a length of 2230 mm under working pressure and a maximum outer diameter of ≤650 mm under working pressure.

[0052] Specifically, the oxygen supply assembly 200 includes an observation window 201 disposed on the side wall of the folding cabin 101, an oxygen supply port 202 disposed on the outer wall of the folding cabin 101, and an oxygen exhaust port 203 on the side wall of the oxygen supply port 202.

[0053] Furthermore, the oxygen supply assembly 200 also includes two reserved ports 204 provided on the side wall of the folding cabin 101. A safety valve 205 is installed on the side wall of one reserved port 204, and a sampling port 206 is provided on the side wall of the safety valve 205. A cabin depressurization port 207 is installed on the side wall of the other reserved port 204.

[0054] Furthermore, the oxygen supply assembly 200 also includes an internal pressure port 208 located on the side wall of the internal and external pressure relief port 207. The side wall of the internal pressure port 208 is provided with an internal temperature measurement port 209. The internal pressure port 208 is a quick-connect interface, which is connected to a pressure gauge, oxygen source, air source, safety valve and environmental gas monitoring device, respectively, and is quick to install.

[0055] Furthermore, the oxygen supply assembly 200 also includes a cabin-inside-outside pressure relief valve 210 located at the end of the folding cabin body 101. A pressure relief valve 211 is installed on the side wall of the cabin-inside-outside pressure relief valve 210. The maximum working pressure of the cabin is 0.18 MPa. The cabin is equipped with a bidirectional adjustable cabin-inside-outside pressure relief valve 210. The status of the personnel inside the cabin can be observed through the observation window 201.

[0056] The rest of the structure is the same as in Example 2.

[0057] Operating Procedure: The person requiring treatment first lies inside the folding chamber 101, then zips up the outer zipper, followed by the inner zipper. Oxygen is then supplied to the folding chamber 101 through the oxygen supply port 202. When exiting after treatment, decompression is achieved through the internal and external decompression ports 207. These ports can be used both internally and externally to decompress, effectively preventing uneven pressure caused by sudden pulling of the double-sided zipper 103 due to excessive internal pressure, thus avoiding the impact of gas. This process also prevents the folding chamber 101 from being filled with oxygen. The expansion causes the pressure-bearing mesh cover 102 to expand as well. During the expansion process, the expansion force and the gravity of the connecting rod 104d effectively attract the magnetic plate 104h. When the folding cabin 101 expands to 80%, the subsequent expansion force drives the connecting rod 104d to move into the interior of the limiting arc plate 104e, and then squeezes the baffle 104f-14, causing the baffle 104f-14 to deflect and drive the anti-detachment plate 104f-15 to move. Thus, the anti-detachment plate 104f-15 seals the limiting arc plate 104e, and then the deflected baffle 104f-15... 14 will compress the limiting block 104f-8 and move it into the first groove 104f-9 for limiting. Then, its moving connecting rod 104d will be stopped by the second groove 104f-10 during the movement. When the device is deflating, its expansion force will gradually decrease. Through the elastic force of the telescopic spring 104f-7, the sliding rod 104f-3 can be effectively moved. The moving sliding rod 104f-3 can drive the limiting block 104f-8 to move. During the movement, the limiting block 104f-8 passes through the first groove 104f-9 and the second groove. 104f-10 pushes out the baffle 104f-14 and the connecting rod 104d respectively. When the limiting block 104d-8 pushes out the connecting rod 104d, the connecting rod 104d is positioned on the anti-detachment plate 104d-15. Thus, the baffle 104f-14 is pressed down by gravity, and the baffle 104f-14 blocks the limiting arc plate 104e, so that the connecting rod 104d cannot move into the interior of the limiting arc plate 104e. This effectively prevents the connecting rod 104d from completely detaching from the limiting arc plate 104e when the folding cabin 101 is venting.
