[0002] The oxygen chamber is equipped with an AED for patients with acute cardiac arrest. If a patient with severe cardiovascular disease experiences cardiac arrest, the AED can be used to defibrillate the patient within the golden four minutes, while simultaneously increasing the oxygen concentration within the chamber, significantly increasing the chances of saving the patient's life. The oxygen chamber's components include an indoor air purification device, an indoor diffuse oxygen concentrator, indoor oxygen sensors, an outdoor oxygen concentrator, a PLC system that automatically controls oxygen concentration and PM2.5 levels, and an AED (automated defibrillator).

[0003] In the prior art, a decompression oxygen chamber releases fresh air and oxygen in the chamber by closing the chamber door and automatically adjusts the oxygen concentration to relieve physical and mental fatigue.

[0004] However, when this type of decompression oxygen chamber is in use, frequently opening the chamber to put items into the chamber will cause the air in the chamber to exchange with the outside air, affecting the oxygen concentration in the chamber. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the background technology that the air in the decompression oxygen chamber is frequently opened, resulting in the exchange of air between the air in the decompression oxygen chamber and the outside air, and to propose a comfortable decompression oxygen chamber.

Elastic bands are fixedly installed at the centers of the ends of the first air baffle and the second air baffle. The openings of the first air baffle and the second air baffle are closed by the elastic band. The exhaust pipe is provided inside the exchange tube and between the first air baffle and the second air baffle.

[0009] The exchange tube is fixedly installed on the side of the reduced pressure oxygen chamber body, and a sealing component is provided at the end of the exchange tube.

[0010] Optionally, an exchange chamber is formed between the exchange tube, the first air baffle and the second air baffle, and two ends of the exchange tube are respectively located at the inner and outer sides of the decompression oxygen chamber body.

[0011] Optionally, the first air baffle and the second air baffle are symmetrically arranged, the opening of the first air baffle and the opening of the second air baffle face each other, and an exhaust fan is arranged inside the exhaust pipe.

[0012] Optionally, the first air baffle is located near one end of the exchange tube outside the decompression oxygen chamber body, and the second air baffle is located at the other end of the exchange tube.

[0013] Optionally, a limiting ring is fixedly installed inside the exhaust pipe, the bottom of the limiting ring is rotatably connected to a one-way baffle, and a torque spring is elastically connected between the one-way baffle and the limiting ring.

[0014] Optionally, the sealing assembly includes a sealing window, a rubber plug and an airbag ring.

[0029] Example 1

[0030] This embodiment proposes a comfortable decompression oxygen chamber, such as Figure 1As shown, it includes a decompression oxygen chamber body 1, a chamber door 2 is rotatably connected to the side of the decompression oxygen chamber body 1, and a slope 3 is fixedly installed on the side of the decompression oxygen chamber body 1 and on the same side as the chamber door 2.

[0031] like Figure 2 and 3 As shown, an exchange assembly 4 is provided on the side of the reduced pressure oxygen warehouse body 1, and the exchange assembly 4 includes an exchange tube 41, a first air baffle 42, a second air baffle 43, an elastic band 44 and an exhaust pipe 45. The exchange tube 41 is fixedly installed on the side of the reduced pressure oxygen warehouse body 1, and the first air baffle 42 and the second air baffle 43 are fixedly installed inside the exchange tube 41. The two ends of the exchange tube 41 are respectively located on the inner and outer sides of the reduced pressure oxygen warehouse body 1. An exchange chamber is formed between the exchange tube 41, the first air baffle 42 and the second air baffle 43. The first air baffle 42 is close to one end of the exchange tube 41 located outside the reduced pressure oxygen warehouse body 1, and the second air baffle 43 is located at the other end of the exchange tube 41.

[0032] By placing items into the exchange chamber for temporary storage, the flow of gas inside the exchange tube 41 is blocked by the first air baffle 42 and the second air baffle 43 to prevent the air inside the decompression oxygen chamber body 1 from directly flowing out of the exchange tube 41 when exchanging items.

[0033] like Figure 3 As shown, the first air baffle 42 and the second air baffle 43 both adopt a trumpet-shaped structure. The first air baffle 42 and the second air baffle 43 are symmetrically arranged, and the opening of the first air baffle 42 and the opening of the second air baffle 43 face each other. Elastic bands 44 are fixedly installed at the centers of the ends of the first air baffle 42 and the second air baffle 43. The openings of the first air baffle 42 and the second air baffle 43 are closed by the elastic band 44. The elastic force of the elastic band 44 reduces the openings of the first air baffle 42 and the second air baffle 43. When in use, the first air baffle 42 and the second air baffle 43 can be opened by directly pulling the elastic band 44 to both sides.

[0034] An exhaust pipe 45 is opened inside the exchange tube 41 and between the first air baffle 42 and the second air baffle 43. An exhaust fan is provided inside the exhaust pipe 45. A limiting ring 47 is fixedly installed inside the exhaust pipe 45. The bottom of the limiting ring 47 is rotatably connected to a one-way baffle 46, and a torque spring is elastically connected between the one-way baffle 46 and the limiting ring 47.

[0035] like Figure 2-4 As shown, a closing component 5 is provided at the end of the exchange tube 41, and the closing component 5 is used to close the end of the exchange tube 41 located outside the reduced-pressure oxygen chamber body 1. After the items are placed in the exchange chamber, the exchange tube 41 is closed by the closing component 5, and the exhaust fan connected to the exhaust pipe 45 is operated to extract the air that enters the exchange chamber due to the exchange of items, thereby preventing the air that enters the exchange chamber from entering the interior of the reduced-pressure oxygen chamber body 1.

[0036] When vacuuming, the one-way baffle 46 rotates downward under the action of air pressure and compresses the torque spring. At this time, the exhaust pipe 45 is connected, and the gas inside the exchange bin is recovered under the action of the exhaust fan. The exhaust fan stops running, and the elastic force of the torque spring resets the one-way baffle 46 and closes the exhaust pipe 45 again. The limiting ring 47 makes the one-way baffle 46 only rotate downward.

[0037] In this embodiment, an exchange chamber is formed by using an exchange tube 41, a first air baffle 42 and a second air baffle 43. The exchange chamber acts as a buffer to reduce the exchange of air inside the reduced-pressure oxygen chamber body 1 with air outside the reduced-pressure oxygen chamber body 1 through the exchange tube 41, thereby affecting the oxygen concentration inside the reduced-pressure oxygen chamber body 1. By placing items into the exchange chamber and using an exhaust fan to exhaust the air in the exchange chamber, external air is prevented from entering the interior of the reduced-pressure oxygen chamber body 1.

[0038] Example 2

[0039] Based on Example 1, this example proposes a comfortable decompression oxygen chamber, such as Figure 2 As shown, the sealing assembly 5 includes a sealing window 51, a rubber plug 52 and an airbag ring 54. The end of the exchange tube 41 is rotatably connected to the sealing window 51, and the rubber plug 52 is fixedly installed on the side of the sealing window 51. The exchange tube 41 is opened and closed by rotating the sealing window 51, and the rubber plug 52 reduces the gap between the exchange tube 41 and the sealing window 51.

[0040] like Figure 2 As shown, an airbag ring 54 is fixedly mounted on the inner wall of the exchange tube 41, located on the left side of the exhaust pipe 45. The rubber plug 52 contacts the airbag ring 54. A fixing ring 53 is fixedly mounted on the inner wall of the exchange tube 41, and the airbag ring 54 is fixedly mounted on the side of the fixing ring 53. The rubber plug 52 and the fixing ring 53 squeeze the airbag ring 54, causing it to deform and further narrow the gap.

[0041] In this embodiment, the exchange tube 41 is opened and closed by rotating the closing window 51, and the rubber plug 52 reduces the gap between the exchange tube 41 and the closing window 51. When the exchange tube 41 is closed, the rubber plug 52 and the fixing ring 53 squeeze the airbag ring 54, and the airbag ring 54 is deformed by the force, further reducing the gap and preventing air leakage inside the decompression oxygen chamber body 1.

[0042] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
