Description

Technical Field

[0001] This invention relates to the field of pressurization chamber technology, and in particular to a pressurization chamber oxygen supply control device. Background Technology

[0002] Soft air pressurization chambers can effectively treat and alleviate a range of symptoms caused by altitude sickness. Altitude sickness is a condition that occurs when the oxygen content in the air is low in high-altitude areas. Inside a soft air pressurization chamber, the body is in a high-pressure environment, which increases the amount of oxygen dissolved in the body and its effective diffusion radius, thereby alleviating the discomfort caused by altitude sickness.

[0003] The soft air pressurization chamber requires the user to lie inside the chamber for treatment. However, when used in the field, the device is prone to rolling when placed directly on the ground, causing it to shift its position. Furthermore, impurities on the ground can easily wear down the chamber and affect its lifespan. Summary of the Invention

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. 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.

[0042] 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.

[0043] Example 1

[0044] Reference Figures 1-6This is the first embodiment of the present invention. This embodiment provides a pressurized chamber oxygen supply control device, which includes a folding member 103 for folding and storing the limiting airbag 101. The hydraulic rod 103e can automatically retract when there is no pressure applied, and then the folding member 103 is stretched to fold in half, which can effectively reduce the storage area.

[0045] Specifically, the airbag assembly 100 includes a limiting airbag 101, a wear-resistant ring 102 disposed on the side wall of the limiting airbag 101, and a folding member 103 disposed on the side wall of the wear-resistant ring 102.

[0046] Furthermore, the folding component 103 includes three sets of retaining sleeves 103a disposed on the side wall of the pressure-bearing mesh cover 202. The retaining sleeves 103a have retaining plates 103b inside. The side wall of the wear-resistant ring 102 is equipped with two support rods 103c. The ends of the two support rods 103c are equipped with hinge blocks 103d. The hydraulic rods 103e are hingedly installed inside the hinge blocks 103d.

[0047] Furthermore, the folding component 103 also includes a threaded rod 103f installed at the end of the hinge block 103d, a fixing block 103g installed at the end of the threaded rod 103f, a hinge shaft 103h installed at the end of the fixing block 103g, the two ends of the hinge shaft 103h being connected to the connecting block 103i, the connecting block 103i being slidably connected to the inner wall of the self-locking sleeve rod 103j, and the self-locking sleeve rod 103j being rotatably connected to the hinge block 103d.

[0048] Furthermore, the connecting block 103i includes a sliding plate 103i-1 disposed inside the self-locking sleeve rod 103j, a connecting cylinder 103i-2 installed at the end of the sliding plate 103i-1, a push rod 103i-3 disposed inside the connecting cylinder 103i-2, a tension spring 103i-4 disposed on the side wall of the push rod 103i-3, and a hinge shaft 103h connected to the sliding plate 103i-1.

[0049] Operating procedure: By rotating the two self-locking sleeves 103j, the self-locking sleeves 103j can drive the threaded rod 103f to move. The moving threaded rod 103f moves to both sides, thereby causing the hydraulic rod 103e to deflect, thus inflating the limiting airbag 101. Then, the limiting airbag 101 is inflated. The inflated limiting airbag 101, through its expansion force, causes the hydraulic rod 103e to extend. When the device is not needed, the gas in the limiting airbag 101 is first released, and then the self-locking sleeves 103j are rotated to drive the threaded rod 103f... When the threaded rod 103f loses its support for the limiting airbag 101, the hydraulic rod 103e can retract, thereby limiting the limiting airbag 101. Then, the two self-locking sleeve rods 103j are pulled to both sides, thereby driving the sliding plate 103i-1 to move. The moving sliding plate 103i-1 can drive the push rod 103i-3 to move. Then, the self-locking sleeve rods 103j are folded downward, which can effectively reduce the storage area occupied. At the same time, the limiting airbags 101 on both sides can effectively reduce the displacement of the folded cabin 201 during use.

[0050] Example 2

[0051] Reference Figures 7-12 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the cabin assembly 200 includes a folding cabin 201 and a pressure-bearing mesh cover 202 disposed on the outer wall of the folding cabin 201. The side wall of the folding cabin 201 is provided with a double-sided zipper 203, and the side wall of the pressure-bearing mesh cover 202 is provided with a tensioning member 204.

[0052] Specifically, the tensioning component 204 includes a fixing strap 204a disposed on the inner wall of the pressure-bearing mesh cover 202, a movable strap 204b installed at one end of the fixing strap 204a, and a connecting block 204c installed at one end of the movable strap 204b; a connecting rod 204d is installed at the end of the connecting block 204c, and six sets of connecting blocks 204c are evenly arranged along the length direction of the folded cabin 201, and the connecting rod 204d is used to connect the six sets of connecting blocks 204c; a limiting arc plate 204e is installed on the inner wall of the connecting rod 204d, an ejection block 204f is disposed on the side wall of the limiting arc plate 204e, a connecting strap 204g is installed at the end of the limiting arc plate 204e, and a magnetic plate 204h is installed inside the connecting strap 204g.

[0053] Furthermore, the ejector block 204f includes a box body 204f-1 disposed on the side wall of the limiting arc plate 204e, the box body 204f-1 is provided with a sliding groove 204f-2, and the sliding groove 204f-2 is provided with a sliding rod 204f-3.

[0054] Furthermore, the ejector block 204f also includes a connecting rod 204f-4 disposed on the side wall of the sliding rod 204f-3, a moving rod 204f-5 installed on the side wall of the connecting rod 204f-4, a fixed cylinder 204f-6 sleeved on the side wall of the moving rod 204f-5, a telescopic spring 204f-7 sleeved on the side wall of the moving rod 204f-5, and a limit block 204f-8 installed at one end of the sliding rod 204f-3.

[0055] Furthermore, the ejector block 204f also includes a first groove 204f-9 provided on the side wall of the limiting block 204f-8, a second groove 204f-10 provided on the side wall of the limiting block 204f-8, a connecting shaft 204f-11 provided inside the limiting arc plate 204e, a limiting plate 204f-12 installed at the end of the connecting shaft 204f-11, a torsion spring 204f-13 sleeved on the side wall of the connecting shaft 204f-11, a baffle 204f-14 installed on the side wall of the connecting shaft 204f-11, and an anti-detachment plate 204f-15 installed on the side wall of the baffle 204f-14.

[0056] The rest of the structure is the same as in Example 1.

[0057] Operating Procedure: The person requiring treatment first lies inside the folding chamber 201, then zips up the outer zipper, followed by the inner zipper. Oxygen is then supplied to the folding chamber 201 through the oxygen supply port 302. When exiting after treatment, decompression is achieved through the internal and external decompression ports 307. These ports can be used both internally and externally to decompress, effectively preventing uneven pressure caused by sudden pulling of the double-sided zipper 203 due to excessive internal pressure, thus avoiding the impact of gas during the filling of the folding chamber 201. The expansion causes the pressure-bearing mesh cover 202 to expand as well. During the expansion process, the expansion force and the gravity of the connecting rod 204d effectively attract the magnetic plate 204h. When the folding cabin 201 expands to 80%, the subsequent expansion force drives the connecting rod 204d to move into the interior of the limiting arc plate 204e, and then squeezes the baffle 204f-14, causing the baffle 204f-14 to deflect and drive the anti-detachment plate 204f-15 to move. Thus, the anti-detachment plate 204f-15 seals the limiting arc plate 204e, and then the deflected baffle 204f-15... 14 will compress the limiting block 204f-8 and move it into the first groove 204f-9 for limiting. Then, its moving connecting rod 204d will be stopped by the second groove 204f-10 during the movement. When the device is deflating, its expansion force will gradually decrease. Through the elastic force of the telescopic spring 204f-7, it can effectively drive the sliding rod 204f-3 to move. The moving sliding rod 204f-3 can drive the limiting block 204f-8 to move. During the movement, the limiting block 204f-8 passes through the first groove 204f-9 and the second groove. 204f-10 pushes out the baffle 204f-14 and the connecting rod 204d respectively. When the limiting block 204d-8 pushes out the connecting rod 204d, the connecting rod 204d is positioned on the anti-detachment plate 204d-15. Thus, the baffle 204f-14 is pressed down by gravity, and the baffle 204f-14 blocks the limiting arc plate 204e, so that the connecting rod 204d cannot move into the interior of the limiting arc plate 204e. This effectively prevents the connecting rod 204d from completely detaching from the limiting arc plate 204e when the folding cabin 201 is venting.

[0058] Example 3

[0059] Reference Figure 1 and Figure 2 as well as Figure 7 This is the third embodiment of the present invention. The difference between this embodiment and the previous embodiments is that the treatment situation of the treatment personnel inside can be observed through the observation window 301, and the treatment personnel inside wear oxygen masks, wherein the waste generated by oxygen inhalation is discharged through the oxygen exhaust port 303.

[0060] Specifically, the oxygen supply assembly 300 includes an observation window 301 located on the side wall of the folding cabin 201, an oxygen supply port 302 located on the outer wall of the folding cabin 201, and an oxygen exhaust port 303 located on the side wall of the oxygen supply port 302. The folding cabin 201 is horizontal and cylindrical, with a length of 2230 mm at working pressure and a maximum outer diameter of ≤650 mm at working pressure. The cabin is equipped with an elliptical transparent observation window 301, and airbag assemblies 100 are located on both sides of the bottom of the cabin.

[0061] Furthermore, the oxygen supply assembly 300 also includes two reserved ports 304 provided on the side wall of the folding cabin 201. A safety valve 305 is installed on the side wall of one reserved port 304, and a sampling port 306 is provided on the side wall of the safety valve 305. An internal and external decompression port 307 is installed on the side wall of the other reserved port 304.

[0062] Furthermore, the oxygen supply assembly 300 also includes an internal pressure port 308 located on the side wall of the internal and external pressure relief port 307. The internal pressure port 308 is a quick-connect interface and is connected to a pressure gauge, oxygen source, air source, safety valve, and environmental gas monitoring device, respectively, allowing for quick installation. The side wall of the internal pressure port 308 is provided with an internal temperature measurement port 309. An internal and external pressure relief valve 310 is installed at the end of the folding cabin body 201, and a pressure relief valve 311 is installed on the side wall of the internal and external pressure relief valve 310.

[0063] The air supply and exhaust system consists of a pressurized air source, indicating instruments, and control valves. The air source consists of three 18L / 15MPa air cylinders.

[0064] Pressure gauges: Two pressure gauges are provided to indicate the pressure inside the chamber, with a maximum range of 1.5 to 2.0 times the maximum working pressure.

[0065] Oxygen supply system: Consists of bottled medical oxygen or other oxygen sources that can stably supply oxygen, indicating instruments, and control valves. The oxygen source consists of one 18L / 15MPa oxygen cylinder, which can continuously supply oxygen for 72 minutes.

[0066] The rest of the structure is the same as in Example 2.

[0067] Operating procedure: The folding chamber 201 is a soft, foldable capsule that serves as both a sealing component and a pressure-bearing component. The pressure-bearing mesh cover 202 is composed of warp and weft mesh belts, which restricts the radial deformation of the soft capsule and increases its pressure resistance. The door adopts a pressure-bearing zipper sealing structure. The higher the pressure, the tighter the seal of the double-sided zipper 203. The maximum working pressure of the chamber is 0.18 MPa, and the number of patients treated inside the chamber is 1.

[0068] When pressurization is required, the gas source is activated to directly pressurize the folding chamber 201, with the pressurization rate controlled by the pressurization and depressurization valves. During depressurization, the chamber's internal and external depressurization valves 310 can directly exhaust gas to the outside, while simultaneously controlling the depressurization rate. After depressurization by the oxygen source depressurization valve, oxygen is supplied directly to the chamber via hoses and quick-connect fittings, and the patient inside inhales oxygen through an oxygen mask. Through this process, the patient breathes pure oxygen under pressure to achieve the therapeutic purpose. The waste oxygen exhaled by the patient is controlled by the oxygen intake and exhaust device and directly discharged to the outside, achieving the goal of controlling the oxygen concentration inside the chamber to not exceed 23%.

[0069] The folding capsule 201 is a sealed component that also has a certain pressure-bearing function. It uses high-strength polyester yarn as the base fabric skeleton material and thermoplastic polyurethane as the polymer material for the capsule's adhesive tape. It has good foldability, light transmittance, high and low temperature performance, and sufficient strength.

[0070] Thermoplastic polyurethane possesses significant advantages such as high strength, good flexibility, excellent resistance to high and low temperatures, resistance to aging, and good water and oil resistance. Its abrasion resistance is ten times that of ordinary rubber. It combines the elasticity of rubber with the thermoplasticity and excellent airtightness of plastics, and its tensile strength can reach over 8000 N / 5 cm, making it an ideal material for capsule construction. The actual capsule material used has a tensile strength of 8000 N / 5 cm and a tensile strength of 133 MPa, meeting the requirements. The adhesive tape was produced using an extrusion casting coating process, then joined using a high-frequency heat-sealing welding process, and the capsule was formed using specialized equipment, ensuring the airtightness and strength requirements of the capsule were met.

[0071] The pressure-bearing mesh cover 202 is the main pressure-bearing component of the folding cabin 201, and it consists of warp and weft mesh belts. The front end of the warp mesh belt is fixed to the front cover, and the rear end is sewn into a whole to restrict the axial deformation of the soft bladder. The weft mesh belt is fastened by a high-strength stainless steel metal connecting rod 204d and a limiting arc plate 204e to restrict the radial deformation of the soft bladder and increase the pressure resistance of the bladder.
