Therefore, they cannot be understood as limiting the present invention.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0017] like Figure 1-Figure 3 As shown in , an embodiment of the present application proposes an air outlet accessory for an oxygen chamber in the first aspect, comprising: a first ventilation component 1, which has a first ventilation part 2 and a first assembly part 3, the first ventilation part 2 is penetrated by a first ventilation hole 4, the first assembly part 3 is connected to the outer periphery of the first ventilation part 2, and at least part of the wall portion of the first ventilation component 1 located at the outer edge of the first ventilation hole 4 expands outward to form an outward expansion part 5; a second ventilation component 6, which has a second ventilation part 7 and a second assembly part 8, the second assembly part 8 is detachably connected to the end of the first ventilation hole 4 away from the outward expansion part 5, the interior of the second assembly part 8 is penetrated, the second ventilation part 7 is provided with a second ventilation hole 9, the second ventilation part 7 and the second assembly part 8 are connected, and the second ventilation hole 9 is communicated with the first ventilation hole 4; and an assembly component 10, which is detachably connected to the outer periphery of the first assembly part 3, and the assembly component 10 is configured to be assembled on the oxygen chamber.

[0018] Based on the above technical solution, the first vent hole 4 of the air outlet accessory can be surrounded by the outward expansion portion 5, which can realize the embedded concealment of the vent end without protruding from the interior surface, which can reduce the accuracy requirements of the opening of the interior surface, and the first vent component 1 and the second vent component 6 can both be used for exhaust or intake, which are flexible to use and multifunctional, and can be well used for oxygen diffusion in the oxygen cabin.

[0019] The gas outlet accessory of the present application can also be used in conjunction with an oxygen chamber for sampling, such as obtaining oxygen coming out of the gas outlet accessory to detect the oxygen concentration and whether it contains other gases.

[0020] In some specific embodiments, the entire wall portion of the first ventilation member 1 located at the outer edge of the first ventilation hole 4 expands outward to form an annular expansion portion 5, that is, one end of the expansion portion 5 surrounds the outer edge of the first ventilation hole 4, so that the first ventilation hole 4 becomes a completely embedded hole. When oxygen diffusion is not performed, the first ventilation hole 4 is connected to the outside world through the expansion portion 5; when oxygen diffusion is performed, the first ventilation hole 4 can be used for air intake or exhaust, and the expansion portion 5 can cover the structure connected to the first ventilation hole 4, and the connection will not be detached due to accidental touch by medical staff, which can ensure that the first ventilation hole 4 can stably intake or exhaust air.

[0021] Generally, if the first vent hole 4 is to be connected, it is necessary to plug in the inside of the first vent hole 4. To facilitate the plugging operation, the inner diameter of the expanded portion 5 gradually decreases from the side away from the first vent hole 4 to the side connected to the outer edge of the first vent hole 4.

[0022] That is, the outward expansion portion 5 is trumpet-shaped, and the inner central angle of its cross section is 60°-90°, preferably 75°.

[0023] In some embodiments, the aperture of the first ventilation hole 4 near the expansion portion 5 is 3mm-6mm, the expansion portion 5 is trumpet-shaped, the minimum inner diameter of the expansion portion 5 is 10mm-15mm, the maximum inner diameter is 45mm-60mm, and the length of the expansion portion 5 is 12mm-20mm. The first ventilation component 1 within this size range can be compatible with the oxygen supply lines of most oxygen chambers.

[0024] Specifically, the first vent 4 includes a first hole segment 11 and a second hole segment 12 connected to each other. The inner diameter of the first hole segment 11 is smaller than the inner diameter of the second hole segment 12. The first hole segment 11 is smaller, which is convenient for plugging the first vent 4. The first hole segment 11 is connected to the interior of the expansion portion 5, and the second hole segment 12 is connected to the second assembly portion 8. The inner diameter of the first hole segment 11 is smaller than or equal to the inner diameter of the second assembly portion 8. Preferably, the inner diameter of the first hole segment 11 is equal to the inner diameter of the second assembly portion 8.

[0025] The second ventilation hole 9 includes a third hole section 13 and a fourth hole section 14 connected to each other. The inner diameter of the third hole section 13 is equal to the inner diameter of the first hole section 11 , and the inner diameter of the fourth hole section 14 is equal to the inner diameter of the second hole section 12 .

[0026] In order to reduce the volume of the second ventilation member 6 to save space, and to extend the length of the second ventilation hole 9 to prolong the ventilation time and control the rate of oxygen ventilation, the present application provides the third hole segment 13 with two parts, the third hole segment 13 having a first part 15 and a second part 16 which are perpendicular to each other, the outer edge of the first part 15 is connected to the second assembly portion 8, and the second part 16 is connected to the fourth hole segment 14.

[0027] When the first ventilation member 1 and the second ventilation member 6 are assembled together, the second assembly portion 8 is completely inserted into the interior of the second hole segment 12, and oxygen flows directly inside the first hole segment 11 and the second assembly portion 8. The inner diameter of the second assembly portion 8 is equal to the inner diameter of the third hole segment 13, and the inner diameters of the first hole segment 11, the second assembly portion 8 and the third hole segment 13 are all smaller than the inner diameter of the fourth hole segment 14. The fourth hole segment 14 is mainly used as an air intake. Oxygen flows inside the third hole segment 13, the second assembly portion 8 and the first hole segment 11 at a uniform flow rate.

[0028] The second assembly portion 8 and the second hole segment 12 are detachably connected, and in order to ensure a stable connection, the present application preferably uses threaded connection between the second assembly portion 8 and the second hole segment 12. In other embodiments, the second assembly portion 8 and the second hole segment 12 can also be plugged in, snapped in, or the like.

[0029] Likewise, in order to ensure a stable connection between the assembly member 10 and the first ventilation member 1 , the assembly member 10 is threadedly connected to the exterior of the first assembly portion 3 .

[0030] The present application adopts a through-plate assembly method to assemble the gas outlet accessories, specifically, the assembly component 10 is assembled on the bracket of the oxygen chamber, and the outer portion of the assembly component 10 can be connected to the groove of the bracket of the oxygen chamber.

[0031] In a second aspect, the embodiment of the present application further proposes an oxygen chamber, comprising an air outlet accessory for the oxygen chamber and an accessory bracket as in the first aspect, wherein the assembly component 10 is assembled on the accessory bracket.

[0032] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
