A type of airbag-assisted oxygen chamber seal

Abstract

This utility model discloses an airbag-type pressure-sealed oxygen chamber, comprising a chamber body with a hatch on one end of its periphery. Two guide rods are installed inside the chamber body, and a hatch corresponding to the hatch is slidably fitted on the inner side of the chamber body. Airbag components and moving components are installed at opposite ends of the hatch. This utility model, through its inflation connector, allows the airbag body to be inflated, causing it to expand and push against the hatch door, thereby sealing the hatch. Simultaneously, when power is off, the inflation connector stops inflating the airbag body, thus opening the hatch. With the airbag body expanding to a diameter of not less than 30mm, the hatch door travel is ensured to be greater than 25mm, resulting in an effective gap between the hatch door and the sealed hatch greater than 20mm. This facilitates airflow within the chamber, allowing for a certain degree of control over carbon dioxide concentration and ensuring a safer environment for the user inside the chamber, thus improving the safety of the chamber's use.

Description

Technical Field

[0001] This utility model relates to the field of medical and health care equipment technology, specifically to an airbag-type oxygen chamber seal. Background Technology

[0002] The oxygen chamber created an oxygen level of 0.3-0.8 kg / cm³. 2 In the atmospheric environment, when a person is in it, due to the increased pressure, a large amount of oxygen dissolves in the blood, significantly increasing the amount of oxygen dissolved in the blood. This also increases the partial pressure of oxygen in the blood, enhances the oxygen diffusion capacity, and expands the effective diffusion radius of oxygen. When people inhale oxygen in the cabin for treatment and health care, it provides effective and sufficient oxygen to the hypoxic body, increases the oxygen content and oxygen storage in tissues, thereby achieving health care and therapeutic effects.

[0003] When people enter and exit the oxygen therapy chamber, they need to slide the door. The door typically has a 20mm gap when opening and closing, which is usually sufficient for oxygen therapy. However, in the event of a power outage or main unit malfunction, if the person receiving oxygen therapy is asleep and cannot slide the door in time, the gap between the door and the frame becomes too small, causing the carbon dioxide concentration to reach over 3000ppm within 5-10 minutes, leading to dizziness. Prolonged exposure can cause severe discomfort, posing a safety hazard to the oxygen therapy chamber. Therefore, there is an urgent need to design an airbag-pressurized oxygen therapy chamber seal to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an airbag-type oxygen chamber seal to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An airbag-type oxygen chamber seal includes a chamber body, with a hatch on one end of the chamber body, two guide rods installed inside the chamber body, and a hatch corresponding to the hatch slidably fitted on the inner side of the chamber body. An airbag assembly and a moving assembly are installed at opposite ends of the hatch.

[0007] The airbag assembly includes an airbag cover installed at one end of the cabin door, an airbag box installed at the lower end of the airbag cover, an airbag body installed inside the airbag box, plugs and inflation connectors respectively installed at opposite ends of the airbag body, and two first rollers installed at opposite ends of the airbag box. The two first rollers and the moving component are slidably engaged with the periphery of the two guide rods, and the expansion diameter of the airbag body is not less than 30mm.

[0008] Furthermore, a sliding sleeve is installed at one end of both the plug and the inflation connector, and a first inverted U-shaped frame is installed on the lower side of both ends of the airbag box, with the first roller rotating and engaging with the inner side of the first inverted U-shaped frame.

[0009] Furthermore, connecting frames are installed at both opposite ends of the hatch, and the moving component includes two second inverted U-shaped frames installed at both opposite ends of one of the connecting frames, and two second rollers rotatably engaged with the inner sides of the two second inverted U-shaped frames.

[0010] Furthermore, the two second rollers are slidably engaged with the periphery of one of the guide rods, the other connecting bracket is fixed to the upper side of the airbag cover, and multiple mounting holes are provided at both opposite ends of the hatch.

[0011] Furthermore, each of the two connecting brackets has a slot on one side that communicates with multiple mounting holes, each mounting hole has a threaded groove, and each slot is fitted with a bolt.

[0012] Furthermore, the bolt is threaded into the threaded groove, and two slide rails corresponding to the hatch are provided on the periphery of the cabin, and the hatch is slidably fitted within the two slide rails.

[0013] Furthermore, two support legs are symmetrically installed on the periphery of the cabin, an inductive power supply is installed on one side of the cabin door, and an airbag inflator corresponding to the inflation connector is installed inside the airbag cover. The inductive power supply is electrically connected to the airbag inflator.

[0014] In the above technical solution, the airbag-type oxygen chamber seal provided by this utility model has the following advantages:

[0015] 1. The airbag body can be inflated through the inflatable connector, causing it to expand and push against the hatch to seal it. When the power is off, the inflatable connector stops inflating the airbag body, causing it to retract and release the pressure on the hatch, thus opening the hatch.

[0016] 2. With an inflation diameter of not less than 30mm, the cabin door travel can be ensured to be greater than 25mm, resulting in an effective gap of more than 20mm between the cabin door and the hatch seal. This facilitates airflow inside the cabin, controls the concentration of carbon dioxide to a certain extent, and ensures that the user inside the cabin is in a relatively safe state, effectively improving the safety of the cabin.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown in the figure, the present invention provides an airbag-type pressure oxygen chamber seal, including a chamber body 1, a hatch 2 opened on one end of the chamber body 1, two guide rods 3 installed inside the chamber body 1, a hatch 4 corresponding to the hatch 2 slidingly fitted on the inner side of the chamber body 1, an airbag assembly and a moving assembly installed at opposite ends of the hatch 4, the airbag assembly including an airbag cover 5 installed at one end of the hatch 4, an airbag box 6 installed at the lower end of the airbag cover 5, an airbag body 7 installed in the airbag box 6, plugs 8 and inflation connectors 9 respectively installed at opposite ends of the airbag body 7, and two first rollers 10 installed at opposite ends of the airbag box 6. The two first rollers 10 and the moving assembly slidely fit on the periphery of the two guide rods 3, and the expansion diameter of the airbag body 7 is not less than 30mm.

[0025] In this embodiment, a cabin 1 is included, a hatch 2 is provided on one side of the cabin 1, and two guide rods 3 are installed inside the cabin 1.

[0026] Specifically, two support legs 19 are symmetrically installed on the periphery of the cabin 1, an inductive power supply 20 is installed on one side of the hatch 4, and an airbag inflator corresponding to the inflation connector 9 is installed inside the airbag cover 5. The inductive power supply 20 is electrically connected to the airbag inflator. The airbag body 7 can be inflated by the airbag inflator to prepare for the next step of closing the hatch 2.

[0027] Specifically, the bolt 17 is threaded into the threaded groove, and two slide rails 18 corresponding to the hatch 2 are provided on the periphery of the compartment 1. The hatch 4 is slidably fitted in the two slide rails 18. The two slide rails 18 can reduce the friction when the hatch 4 moves, thereby driving the hatch 4 to slide quickly.

[0028] In this embodiment, the inner side of the cabin 1 is slidably fitted with a hatch 4 corresponding to the hatch 2, and airbag components and moving components are installed at opposite ends of the hatch 4.

[0029] Specifically, connecting frames 13 are installed at both ends of the hatch 4. The moving component includes two second inverted U-shaped frames 14 installed at both ends of one of the connecting frames 13 and two second rollers 15 rotatably engaged with the inner side of the two second inverted U-shaped frames 14. The two second rollers 15 are slidably engaged with the periphery of one of the guide rods 3, thereby moving the hatch 4 to prepare for the next step of opening or closing the hatch 2.

[0030] Specifically, two second rollers 15 are slidably engaged with the periphery of one of its guide rods 3, and the other connecting frame 13 is fixed to the upper side of the airbag cover 5. Multiple mounting holes 16 are provided at both opposite ends of the hatch 4.

[0031] Specifically, each of the two connecting brackets 13 has a slot on one side that communicates with multiple mounting holes 16. Each mounting hole 16 has a threaded groove, and each slot is fitted with a bolt 17. The bolt 17 engages with the threaded groove, thereby fixing the airbag assembly, the moving assembly, and the hatch 4 together.

[0032] In this embodiment, the airbag assembly includes an airbag cover 5 installed at one end of the cabin door 4, an airbag box 6 installed at the lower end of the airbag cover 5, an airbag body 7 installed inside the airbag box 6, plugs 8 and inflation connectors 9 respectively installed at opposite ends of the airbag body 7, and two first rollers 10 installed at opposite ends of the airbag box 6. The two first rollers 10 and the moving assembly are slidably fitted around the periphery of the two guide rods 3, and the expansion diameter of the airbag body 7 is not less than 30mm.

[0033] Specifically, the end of the plug 8 and the inflation connector 9 are each equipped with a sliding sleeve 11, and the lower side of the opposite ends of the airbag box 6 is equipped with a first inverted U-shaped frame 12. The first roller 10 rotates and engages with the inner side of the first inverted U-shaped frame 12. Through the two sliding sleeves 11, the airbag cover 5 can remain silent when moving inside the cabin 1.

[0034] Working steps: 1. When it is necessary to seal hatch 2, the user first manually pushes hatch 4 and starts induction power 20 to open hatch 2. Then the user enters the cabin 1. At this time, induction power 20 provides power to the airbag inflator, so that the airbag inflator inflates the airbag body 7 through the inflation connector 9. As a result, the airbag body 7 expands and pushes the hatch 4, and the hatch 4 seals hatch 2.

[0035] 2. When the power to cabin 1 is cut off, the pressure inside cabin 1 is zero. Then, the inductive power supply 20 stops providing power to the airbag inflator. At this time, the airbag inflator deflates the airbag body 7 through the inflation connector 9. Simultaneously, the airbag body 7 retracts, thus canceling the push on the hatch 4. At this time, the two first rollers 10 and the two second rollers 15 slide around the two guide rods 3, and the hatch 4 slides on the two slide rails 18, thereby opening the hatch 2. At the same time, the expansion diameter of the airbag body 7 is not less than 30mm, which can ensure that the travel of the hatch 4 is greater than 25mm, so that the effective gap between the hatch 4 and the hatch 2 is greater than 20mm, which facilitates the airflow inside the cabin and ensures that the user inside cabin 1 is in a relatively safe state.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
