[0002] A hyperbaric oxygen chamber is a special medical device for hyperbaric oxygen therapy. According to different pressurizing media, it is divided into two types: air pressurized chamber and pure oxygen pressurized chamber. Clinically, it is mainly used for the treatment of anaerobic infections, CO poisoning, air embolism, decompression sickness, ischemic hypoxic encephalopathy, brain trauma, cerebrovascular diseases, etc.

[0003] Due to the large gas flow at the air inlet of the hyperbaric oxygen chamber and the small cross-sectional area at the air inlet, it will cause relatively large noise, seriously affecting the user experience. Summary of the Utility Model

Description of the Drawings

[0018] Figure 1 is an exploded view of a sound insulation device according to an embodiment of the present invention;

[0019] Figure 2 is a cross-sectional view of a sound insulation nozzle according to an embodiment of the present invention. Detailed Embodiments

[0020] To make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings.

[0021] See Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a sound insulation device for a hyperbaric oxygen chamber, including a device body 1 and a sound insulation nozzle 2.

[0022] In the embodiment of the present invention, a sound insulation device is provided at the air outlet of the hyperbaric oxygen chamber to solve the problem of large noise during the air intake of the hyperbaric oxygen chamber.

[0023] Specifically, a processing gas chamber 11 is provided inside the device body 1. An air outlet 12 is provided at one end of the processing gas chamber 11, and an air inlet is provided at the other end. The silencing nozzle 2 is connected to the air inlet;

[0024] The silencing nozzle 2 includes a nozzle housing 21. A connection port 22 is provided at the top of the nozzle housing 21. The connection port 22 is connected to the air inlet. A silencing structure 23 is provided inside the cavity of the nozzle housing 21. A transition air hole 24 is provided inside the silencing structure 23. Silencing chambers 25 are provided both from the transition air hole 24 to the top of the silencing structure 23 and from the transition air hole 24 to the bottom of the silencing structure 23. The silencing chambers 25 gradually increase from the transition air hole 24 to the end of the silencing structure 23. The silencing chamber 25 at the top of the silencing structure 23 is communicated with the connection port 22. Exhaust holes 26 are provided on the outer side wall of the nozzle housing 21.

[0025] When the utility model works, high-pressure oxygen enters the connection port 22 of the silencing nozzle 2 from the air inlet, and then enters the silencing chamber 25 from the connection port 22. Since the silencing chamber 25 presents a horn-shaped structure, it plays a role in reversing the high-pressure oxygen, avoiding the phenomenon of gas turbulence. Then, after passing through the transition air hole 24, the cross-sectional area of the silencing chamber 25 gradually increases, reducing the flow rate of the high-pressure oxygen, and finally discharging from the exhaust holes 26 at the nozzle housing 21. Compared with the prior art, the structure of the silencing chamber 25 can decelerate the gas passing through the transition air hole 24 and avoid the phenomenon of gas turbulence, effectively solving the problem of large noise during the operation of the high-pressure oxygen chamber.

[0026] Preferably, the radius of the connection port 22 is smaller than the radius of the transition air hole 24. The radius of the connection port 22 being smaller than that of the transition air hole 24 can enable the high-pressure oxygen to quickly diffuse after entering the silencing chamber 25, reducing the gas flow rate. At the same time, under the guiding action of the inner wall of the silencing chamber 25, it flows towards the transition air hole 24, thereby effectively reducing the noise of the high-pressure oxygen after spraying out of the connection port.

[0027] More preferably, the radius of the connection port 22 is 40%-80% of the radius of the transition air hole 24. When the radius of the connection port 22 accounts for less than 40% of the radius of the transition air hole, the radius of the connection port 22 is too small, and the high-pressure oxygen cannot diffuse in time after entering the silencing chamber 25. When the radius of the connection port 22 accounts for more than 80% of the radius of the transition air hole 24, the connection port 22 is too large, and the high-pressure gas is likely to come into contact with the inner wall of the silencing chamber 25 prematurely, easily generating gas turbulence.

[0028] Preferably, a plurality of the exhaust holes 26 are provided on the outer side surface of the nozzle housing 21 and arranged at a predetermined interval. Arranging a plurality of exhaust holes 26 is beneficial to improving the exhaust efficiency of the silencing nozzle 2. More preferably, the exhaust holes 26 are in a strip structure.

[0029] Preferably, a disinfection lamp 13 is provided on one inner wall of the processing air chamber 11. The disinfection lamp 13 can disinfect the oxygen in the processing air chamber 11 to achieve a sterile effect. The disinfection lamp 13 is an ultraviolet disinfection lamp.

[0030] More preferably, an aviation plug 14 is provided on the inner wall of the processing air chamber 11 opposite to the disinfection lamp 13, and the disinfection lamp 13 is electrically connected to the aviation plug 141. Through the aviation plug 14, the disinfection lamp can be electrically connected to an external power supply to obtain power.

[0031] Preferably, an inlet bellows joint 15 is provided at the position of the air inlet of the device body 1. To improve the connection position for connection with a high-pressure oxygen cylinder.

[0032] Correspondingly, an embodiment of the present invention further provides a hyperbaric oxygen chamber, including the sound insulation device described above.

[0033] The sound insulation device of the present invention can effectively reduce the airflow sound during the operation of the hyperbaric oxygen chamber, and has an obvious noise reduction effect, and can reduce the airflow sound by 20 dB or more.

[0034] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
