Description

Technical Field

[0001] This utility model relates to the field of sealing technology for hyperbaric oxygen chambers, specifically a sealing structure for hyperbaric oxygen chambers. Background Technology

[0002] A hyperbaric oxygen chamber is a medical device primarily used to treat specific conditions such as decompression sickness, carbon monoxide poisoning, and chronic wound healing. It increases the oxygen content in the blood and tissues by increasing the partial pressure of oxygen, thereby promoting healing and improving bodily functions. Hyperbaric oxygen chambers deliver pure or highly concentrated oxygen to patients at pressures higher than atmospheric pressure (typically 1.5 to 3 times atmospheric pressure). Under high pressure, the amount of oxygen dissolved in the blood increases significantly, which helps to rapidly repair damaged tissues and organs. Treatment for deep-sea divers, where rapid ascent after diving can lead to bubble formation, requires the elimination of these bubbles in a high-pressure environment. Only professionally trained medical personnel can operate hyperbaric oxygen chambers to ensure patient safety. The design and operation of hyperbaric oxygen chambers must comply with relevant medical safety standards, such as FDA and ISO, to guarantee the effectiveness and safety of the equipment.

[0003] In traditional hyperbaric oxygen chambers, sealing gaskets are typically installed at the edges of the chamber doors to achieve an internal seal. However, in inflatable hyperbaric oxygen chambers, this traditional sealing method cannot fully exert its sealing effect, resulting in insufficient internal sealing performance and thus reducing the quality of use of the hyperbaric oxygen chamber. To address this, we propose a sealing structure for hyperbaric oxygen chambers. Utility Model Content

[0004] The purpose of this invention is to provide a sealing structure for a hyperbaric oxygen chamber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for a hyperbaric oxygen chamber, comprising a chamber body, an inflatable airbag fixedly connected to one side of the chamber body, an oxygen supply box fixedly connected to one side of the chamber body, an oxygen supply groove provided on one side of the oxygen supply box, the oxygen supply groove communicating with the interior of the oxygen supply box, a gas guide pipe fixedly connected to one side of the oxygen supply box, one end of the gas guide pipe communicating with the interior of the oxygen supply box, and the end of the gas guide pipe away from the oxygen supply box communicating with the interior of the inflatable airbag, a zipper structure provided on one side of the chamber body, an oxygen supply port provided on one side of the chamber body, the oxygen supply port communicating with the interior of the chamber body, and an assembly structure provided on the outer side of the oxygen supply port.

[0006] As a further preferred embodiment of this technical solution, the zipper structure includes a zipper groove, which is formed on one side of the cabin and extends through to the inside of the cabin and is located inside the inflated airbag.

[0007] As a further preferred embodiment of this technical solution, a locking block is slidably connected to the outer side of the zipper groove, a fixing block is fixedly connected to one side of the locking block, and a pull ring is rotatably connected to the outer side of the fixing block.

[0008] As a further preferred embodiment of this technical solution, the assembly structure includes a sealing gasket, which is fixedly connected to one end of the oxygen supply port. An oxygen supply tube is slidably connected to the inner side of the oxygen supply port, and a baffle is fixedly connected to the outer side of the oxygen supply tube. One side of the baffle abuts against one side of the sealing gasket.

[0009] As a further preferred embodiment of this technical solution, a locking sleeve is threadedly connected to the outer side of the oxygen supply port, the inner side of the locking sleeve contacts one side of the baffle, and a protrusion is fixedly connected to the outer side of the locking sleeve.

[0010] As a further preferred embodiment of this technical solution, a pressure relief port is provided on one side of the cabin, and a pressure regulating hole is provided on the outer side of the pressure relief port.

[0011] As a further preferred embodiment of this technical solution, a plug is threadedly connected to the inner side of the pressure relief port, a limiting plate is fixedly connected to one side of the plug, the limiting plate is in contact with one end of the pressure relief port, and a torsion block is fixedly connected to one side of the limiting plate.

[0012] This utility model provides a sealing structure for a hyperbaric oxygen chamber, which has the following advantages:

[0013] (1) By setting a zipper structure, the present invention achieves closed protection of the interior of the chamber before use. Then, by setting the assembly structure, the oxygen supply port is sealed. When in use, the chamber is opened by the zipper structure, and oxygen enters the interior of the oxygen supply box through the oxygen supply port. The oxygen is then evenly distributed to the interior of the chamber through the oxygen supply groove. At the same time, some oxygen is transported to the interior of the expansion airbag through the air guide tube, so that the expansion airbag expands and is squeezed to achieve a better sealing treatment effect. This not only improves the sealing performance of the hyperbaric oxygen chamber, but also improves the quality of use of the hyperbaric oxygen chamber.

[0014] (2) This utility model uses a twisting block on one side of the limiting plate to make the plug connected to the inner thread of the pressure relief port, thereby further enhancing the sealing of the hyperbaric oxygen chamber. When the pressure inside the chamber is too high, rotating the twisting block can drive the plug out, and then release part of the pressure inside the hyperbaric oxygen chamber through the pressure regulating hole, thereby effectively regulating the pressure of the hyperbaric oxygen chamber. This not only further improves the safety of the hyperbaric oxygen chamber, but also further enhances its therapeutic effect. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1-7 As shown, in this embodiment, a sealing structure for a hyperbaric oxygen chamber includes a chamber body 1. An inflatable airbag 13 is fixedly connected to one side of the interior of the chamber body 1. An oxygen supply box 10 is fixedly connected to one side of the interior of the chamber body 1. An oxygen supply groove 11 is provided on one side of the oxygen supply box 10, and the oxygen supply groove 11 communicates with the interior of the oxygen supply box 10. A gas guide pipe 12 is fixedly connected to one side of the oxygen supply box 10. One end of the gas guide pipe 12 communicates with the interior of the oxygen supply box 10, and the end of the gas guide pipe 12 away from the oxygen supply box 10 is connected to the inflatable airbag 13. The interior of compartment 3 is open. A zipper structure is provided on one side of compartment 1. An oxygen supply port 14 is provided on one side of compartment 1. The oxygen supply port 14 is open to the interior of compartment 1. An assembly structure is provided on the outside of the oxygen supply port 14. A pressure relief port 6 is provided on one side of compartment 1. A pressure regulating hole 7 is provided on the outside of pressure relief port 6. A plug 20 is threadedly connected to the inside of pressure relief port 6. A limit plate 8 is fixedly connected to one side of the plug 20. The limit plate 8 contacts one end of pressure relief port 6. A torsion block 9 is fixedly connected to one side of the limit plate 8.

[0025] When using a hyperbaric oxygen chamber, the chamber 1 is first opened by setting up a zipper structure. The injured person places their hand inside the chamber 1. Then, the assembly structure ensures that the outer side of the oxygen supply port 14 is fully sealed. Next, the toggle block 9 is rotated, causing the block 20 to rotate inside the pressure relief port 6. At the same time, the limiting plate 8 abuts against the pressure relief port 6. Oxygen then enters the oxygen supply box 10 through the oxygen supply port 14 and is evenly distributed to the interior of the chamber 1 through the oxygen supply groove 11. Some oxygen enters the inflatable airbag 13 through the air guide tube 12. As the inflatable airbag 13 expands, it compresses the injured person's wrist, thus fully sealing the interior of the chamber 1. When the pressure inside the chamber 1 is too high, the toggle block 9 can be rotated, causing the block 20 to rotate outward. Then, some of the pressure inside the chamber 1 is released through the pressure regulating hole 7. This enhances the effectiveness of the hyperbaric oxygen chamber and improves its sealing performance.

[0026] like Figures 1-7 As shown, the zipper structure includes a zipper groove 5, which is opened on one side of the cabin 1. The zipper groove 5 extends through to the inside of the cabin 1 and is located inside the inflated airbag 13. A locking block 15 is slidably connected to the outside of the zipper groove 5. A fixing block 16 is fixedly connected to one side of the locking block 15. A pull ring 17 is rotatably connected to the outside of the fixing block 16.

[0027] By setting a pull ring 17 on the top of the fixing block 16, the zipper groove 5 can be opened or closed. Then, by pulling the pull ring 17, the locking block 15 moves outside the zipper groove 5, thereby opening or closing the zipper groove 5, so that the injured person can put their arm into the hyperbaric oxygen chamber, and at the same time, it is easy to close the hyperbaric oxygen chamber, thereby enhancing the convenience of the hyperbaric oxygen chamber.

[0028] like Figures 1-7 As shown, the assembly structure includes a sealing gasket 18, which is fixedly connected to one end of the oxygen supply port 14. An oxygen supply tube 2 is slidably connected to the inner side of the oxygen supply port 14, and a baffle 19 is fixedly connected to the outer side of the oxygen supply tube 2. One side of the baffle 19 abuts against one side of the sealing gasket 18. A locking sleeve 3 is threadedly connected to the outer side of the oxygen supply port 14. The inner side of the locking sleeve 3 contacts one side of the baffle 19, and a protrusion 4 is fixedly connected to the outer side of the locking sleeve 3.

[0029] By setting a protrusion 4 on the outside of the locking sleeve 3, the locking sleeve 3 can be rotated and rotated on the outside of the oxygen supply port 14. Then the locking sleeve 3 squeezes the baffle 19 and makes the sealing gasket 18 fully contact the oxygen supply port 14, so as to efficiently complete the sealing and fixing connection between the oxygen supply pipe 2 and the oxygen supply port 14, and further improve the sealing performance of the hyperbaric oxygen chamber.

[0030] This utility model provides a sealing structure for a hyperbaric oxygen chamber. The specific working principle is as follows: When using the hyperbaric oxygen chamber, first pull the pull ring 17, causing the locking block 15 to move outside the pull lock groove 5, thereby opening the pull lock groove 5 and simultaneously opening the chamber body 1. The injured person places their hands inside the chamber body 1. Then, rotate the protrusion 4 to drive the locking sleeve 3 to rotate outside the oxygen supply port 14. Subsequently, the locking sleeve 3 presses against the baffle 19, causing the sealing gasket 18 to fully contact the oxygen supply port 14, thus quickly completing the sealed and fixed connection between the oxygen supply pipe 2 and the oxygen supply port 14, ensuring a full seal on the outside of the oxygen supply port 14. Then, rotate the torsion block 9, causing... The plug 20 rotates inside the pressure relief port 6, while the limiting plate 8 abuts against the pressure relief port 6. Then, oxygen enters the oxygen supply box 10 through the oxygen supply port 14 and is evenly distributed to the interior of the chamber 1 through the oxygen supply groove 11. Some oxygen enters the interior of the expansion airbag 13 through the air guide tube 12. As the expansion airbag 13 expands, it compresses the injured person's wrist, thereby fully sealing the interior of the chamber 1. When the pressure inside the chamber 1 is too high, the toggle block 9 can be rotated to make the plug 20 rotate outward, and then release part of the pressure inside the chamber 1 through the pressure regulating hole 7, thus completing the sealed use of the hyperbaric oxygen chamber.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
