Description

Technical Field

[0001] The present invention relates to the technical field of oxygen chambers, in particular to a composite soft oxygen chamber and a use method thereof. Background Art

[0002] Oxygen chamber is a special medical device for hyperbaric oxygen therapy. Its principle is to place the user in an oxygen-rich environment with a pressure higher than normal atmospheric pressure. Under the action of high pressure, oxygen is input into the respiratory and microcirculatory systems and reaches various organs of the human body to increase the level of arterial oxygen partial pressure and oxygen saturation to promote human metabolism. Oxygen chambers can be divided into soft oxygen chambers and hard oxygen chambers. Compared with hard oxygen chambers, soft oxygen chambers have the advantages of easy storage and low manufacturing cost, and are widely used. Currently, the commonly used soft oxygen chambers are mostly made of TPU material and spliced ​​by bonding. The appearance shape is mostly capsule-shaped, which is convenient for users to lie flat and has good pressure resistance. The inlet and outlet are long strips, designed with zippers, and sealed with sealing rubber inside. However, compared with hard oxygen chambers, the pressure resistance of the soft oxygen chamber cabin material is poor. When the internal pressure increases, the entire cabin will be greatly deformed. Therefore, when higher pressure is required, there is often a risk of rupture. Summary of the invention

[0003] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions.

[0004] A composite soft oxygen chamber is designed, comprising a high-pressure chamber, a medium-pressure chamber, and a low-pressure chamber which are sequentially connected from the inside to the outside, and the bottoms of every two adjacent chambers are fixedly connected, and the tops are connected and supported by supporting members, a zipper and a manual pressure relief valve are respectively provided on one side of the high-pressure chamber, the medium-pressure chamber, and the low-pressure chamber, and a group of oxygen inlet and air inlet are respectively provided on the other side, and the three groups of oxygen inlet and air inlet are all connected, and a high-pressure automatic pressure relief valve, a medium-pressure automatic pressure relief valve, and a low-pressure automatic pressure relief valve are respectively provided on each chamber.

[0005] Preferably, the support member is made of oxygen cabin body material.

[0006] Preferably, there are a plurality of support members, which are distributed in a circular array at the top edges of the medium-pressure cabin and the low-pressure cabin.

[0007] Preferably, the bottoms of two adjacent cabins are respectively bonded and fixed by silicone.

[0008] Preferably, through-plate quick-plug interfaces are respectively provided on one side of the medium-pressure cabin and the high-pressure cabin, which are respectively connected to the air inlet and the oxygen inlet through pipelines.

[0009] Preferably, the pressures borne by the low-pressure cabin, the medium-pressure cabin and the high-pressure cabin increase in sequence.

[0010] Preferably, the relief pressure of each automatic pressure relief valve is equal to the pressure difference between inside and outside of each cabin.

[0011] Preferably, one side of each cabin is arranged close to each other.

[0012] Preferably, the high-pressure cabin, the medium-pressure cabin and the low-pressure cabin are all cylindrical, with an arc surface on the top and a flat surface on the bottom.

[0013] A method for using a composite soft oxygen chamber comprises the following steps:

[0014] S1, first, connect the air inlet and oxygen inlet to the external air source and oxygen source respectively, unzip the high-pressure cabin and the medium-pressure cabin, tighten the hatch zipper of the low-pressure cabin, and tighten the manual pressure relief valve to make the outermost cabin in a sealed state;

[0015] S2, start to inflate the cabin. When the cabin is initially formed, the user unzips the outermost low-pressure cabin to enter the cabin and tightens the zipper. At this time, the cabin pressure continues to rise until the low-pressure cabin automatic pressure relief valve starts to release pressure, so that the cabin pressure is maintained within a stable range. The user can then receive treatment in a low-pressure state.

[0016] When the user needs higher pressure treatment, he / she needs to enter the medium pressure cabin and tighten the zipper of the medium pressure cabin. At this time, the medium pressure cabin forms a sealed space and starts to increase the pressure until the automatic pressure relief valve of the medium pressure cabin starts to operate. At this time, the user can receive treatment under medium pressure; when the user needs higher pressure treatment, he / she needs to enter the hyperbaric cabin and tighten the zipper of the hyperbaric cabin. At this time, the hyperbaric cabin forms a sealed space and starts to increase the pressure until the automatic pressure relief valve of the hyperbaric cabin starts to operate. At this time, the user can receive treatment under high pressure;

[0017] S3, when the user needs decompression treatment or ends the treatment, first open the manual pressure relief valve in the cabin. When the pressure in the cabin is balanced with the external pressure, open the zipper of the cabin, and so on from the inside to the outside, and then gradually exit the cabin.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention adopts the design of high-pressure cabin, medium-pressure cabin and low-pressure cabin which are connected from inside to outside in sequence. Each cabin can independently withstand different pressure levels, effectively dispersing the overall pressure and reducing the risk of rupture of a single cabin due to excessive pressure. The intelligent control mechanism of the automatic pressure relief valve ensures that the pressure difference between the inside and outside of the cabin is maintained within a safe range, thus improving the safety of use.

[0020] 2. The present invention adopts a step-by-step pressure adjustment method, allowing users to gradually adapt to different pressure environments, avoiding the discomfort caused by rapid pressure changes, and providing patients with a more comfortable hyperbaric oxygen therapy experience. The zipper and manual pressure relief valve are set to facilitate users to independently control the cabin environment and increase the flexibility of use.

[0021] 3. The cabin of the present invention adopts a cylindrical structure, with a rounded corner design on the top arc surface and the bottom plane, which is not only beautiful but also more uniform in force, reducing the problem of local stress concentration and extending the service life. The use of silicone bonding and support members distributed in an annular array enhances the overall stability of the structure.

[0022] 4. The compartment design of the composite soft oxygen chamber of the present invention allows the selection of chambers with different pressure levels according to treatment needs, realizing the flexible application of personalized treatment plans. The setting of the through-board quick-plug interface simplifies the supply connection of oxygen and air, which is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Example 1

[0035] A composite soft oxygen chamber, such as Figures 1 to 9 As shown, it includes a high-pressure cabin 7, a medium-pressure cabin 5, and a low-pressure cabin 4 which are sequentially connected from the inside to the outside. One side of each cabin body 1 is arranged close to each other to increase the accommodation space of each cabin body 1. The high-pressure cabin 7, the medium-pressure cabin 5, and the low-pressure cabin 4 are all cylindrical structures, with a circular arc surface on the top and a flat bottom with a large fillet to make the force more uniform. The bottoms of every two adjacent cabin bodies 1 are respectively bonded and fixed by silica gel 13, and the tops are connected and supported by multiple support members 6. The support members 6 are made of the same material as the oxygen cabin body 1, and are respectively distributed in a circular array at the top edges of the medium-pressure cabin 5 and the low-pressure cabin 4.

[0036] A zipper 2 and a manual pressure relief valve 3 are respectively provided on one side surface of the high-pressure cabin 7, the medium-pressure cabin 5, and the low-pressure cabin 4. In order to facilitate user operation, the zipper 2 and the manual pressure relief valve 3 can be arranged on one side, and a group of oxygen inlet 8 and air inlet 9 are respectively provided on the other side, and the three groups of oxygen inlet 8 and air inlet 9 are all connected. Through-plate quick-plug interfaces are respectively provided on one side of the medium-pressure cabin 5 and the high-pressure cabin 7, which are respectively connected to the air inlet 9 and the oxygen inlet 8 through pipelines. The pressures borne by the low-pressure cabin 4, the medium-pressure cabin 5 and the high-pressure cabin 7 increase in sequence. A high-pressure automatic pressure relief valve 10, a medium-pressure automatic pressure relief valve 11 and a low-pressure automatic pressure relief valve 12 are respectively provided on each cabin body 1. The pressure in each cabin body 1 is controlled by the corresponding high-pressure automatic pressure relief valve 10, the medium-pressure automatic pressure relief valve 11 and the low-pressure automatic pressure relief valve 12. The pressure relief pressure of each automatic pressure relief valve is equal to the pressure difference between the inside and outside of each cabin body 1. It is assumed that when used normally under atmospheric pressure, the pressure difference between the inside and outside of the low-pressure cabin 4 is P1, the pressure difference between the inside and outside of the medium-pressure cabin 5 is P2-P1, and the pressure difference between the inside and outside of the high-pressure cabin 7 is P3-P2. When P1=30kpa, P2=60kpa, and P3=90kpa, the pressure relief pressure values ​​of the three automatic pressure relief valves are all 30kpa.

[0037] Working principle: The composite soft oxygen chamber of the present invention uses a multi-level structure to adjust the internal pressure in steps. At the beginning of treatment, first ensure that the low-pressure chamber 4 is sealed and start to inflate. As the gas is injected, the pressure in the chamber gradually rises to the preset value (P1), and the low-pressure automatic pressure relief valve 12 is activated at this pressure point to keep the pressure in the chamber stable. When higher pressure treatment is required, the user enters the medium-pressure chamber 5 and seals it. The medium-pressure chamber 5 is then inflated to the set P2 value, and the medium-pressure automatic pressure relief valve 11 works to maintain a stable pressure in the chamber. The same principle is applied to the high-pressure chamber 7 to reach the P3 pressure level for treatment. Throughout the process, the connection and support design between the cabins 1 ensures that each cabin 1 can work independently and cooperate in pressurization. At the same time, the manual pressure relief valve 3 and the zipper 2 mechanism provide the user with the necessary pressure adjustment and entry and exit channels to ensure the safety and efficiency of the treatment process.

[0038] Example 2

[0039] A method for using a composite soft oxygen chamber comprises the following steps:

[0040] S1, first, connect the air inlet 9 and the oxygen inlet 8 to the external air source and oxygen source respectively, open the zippers 2 of the high-pressure cabin 7 and the medium-pressure cabin 5, tighten the zipper 2 of the door of the low-pressure cabin 4, and tighten the manual pressure relief valve 3 to make the outermost cabin 1 in a sealed state;

[0041] S2, start to inflate the cabin 1. When the cabin 1 is initially formed, the user opens the zipper 2 of the outermost low-pressure cabin 4 to enter the low-pressure cabin 4 and tightens the zipper 2. At this time, the pressure in the cabin continues to rise until the low-pressure automatic pressure relief valve 12 starts to release pressure, so that the pressure in the cabin is maintained within a stable range, and the user can receive treatment in a low-pressure state;

[0042] When the user needs higher pressure treatment, he needs to enter the medium pressure cabin 5 and tighten the zipper 2 of the medium pressure cabin 5. At this time, the medium pressure cabin 5 forms a sealed space and starts to increase the pressure until the medium pressure automatic pressure relief valve 11 starts to operate. At this time, the user can be treated under the medium pressure state; when the user needs higher pressure treatment, he needs to enter the hyperbaric cabin 7 and tighten the zipper 2 of the hyperbaric cabin 7. At this time, the hyperbaric cabin 7 forms a sealed space and starts to increase the pressure until the hyperbaric cabin 7 automatic pressure relief valve starts to operate. At this time, the user can be treated under the high pressure state;

[0043] S3, when the user needs decompression treatment or ends the treatment, first open the manual pressure relief valve 3 in the cabin 1. When the pressure in the cabin 1 is balanced with the external pressure, open the zipper 2 of the cabin 1, and so on from the inside to the outside, and gradually exit to the outside of the cabin.

[0044] The present invention adopts a multi-layer composite cabin 1 design, creating a plurality of independent cavities that are completely embedded inside, so that when the cabin pressure of each cabin 1 gradually increases relative to the atmospheric pressure, the internal and external pressure difference is always maintained at a low level, thereby ensuring that the cabin 1 material will not produce large deformation and stress, thereby effectively reducing the risk of cabin 1 rupture; in addition, the step-by-step pressure change also helps the user better adapt to the changes in pressure increase or decrease, making it convenient for the user to choose the appropriate time for blood pressure increase or decrease treatment according to their own situation.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
