[0002] The high-pressure oxygen chamber safety valve is an important safety device used to regulate and release the oxygen pressure inside the high-pressure oxygen chamber to prevent excessive pressure from causing harm to the chamber body and personnel. The high-pressure oxygen chamber is a dedicated medical device for hyperbaric oxygen therapy. According to the different pressurizing media, it is divided into two types: air pressurized chamber and pure oxygen pressurized chamber. The high-pressure oxygen chamber has a wide range of applications. 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. In the medical and health industries, the oxygen chamber can be used for oxygen therapy for people with altitude sickness and altitude-related diseases, as well as for middle-aged and elderly people with weak constitutions, those who overuse their brains, and people working and living in oxygen-deficient environments. With the popularization of hyperbaric gas treatment, the application of high-pressure gas chambers in China has developed rapidly. Although the number of adverse events of high-pressure oxygen chambers received is small, the nature is serious, and the causes are mostly due to improper operation. Therefore, relevant medical institutions are reminded to strengthen safety training and patient education, remind patients to strengthen their self-protection awareness, strictly abide by the instructions for entering the chamber, report problems to medical staff in a timely manner, and further emphasize safety precautions in a prominent manner in the random documents to avoid the use risks of the product.

[0003] At present, most of the safety valves of oxygen chambers have certain drawbacks in use. Moreover, traditional automatically controlled regulating valves that are easy to connect are difficult to intelligently control the flow rate, thus reducing the practicality of the automatically controlled regulating valves that are easy to connect. In addition, most of the automatically controlled regulating valves that are easy to connect are difficult to be quickly fixed, which brings inconvenience to the use of the automatically controlled regulating valves that are easy to connect. And the content of the discharged oxygen cannot be known, so the oxygen content inside the oxygen chamber cannot be known. Therefore, an oxygen chamber safety valve is needed to improve the above problems. Content of the Utility Model

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Embodiment: Please refer to Figures 1-4 A shown oxygen chamber safety valve, including a main body 1, a valve body assembly 2 is fixedly connected to the side of the main body 1, and a filter and air release assembly 3 is fixedly connected to the side of the valve body assembly 2;

[0026] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3As shown, the main body 1 includes an exhaust pipe 101. A flow sensor 102 is fixedly connected to the side of the exhaust pipe 101. The valve body assembly 2 includes a valve chamber 201. An electric control actuator 202 is fixedly connected to the top of the valve chamber 201. A signal transceiver 203 is fixedly connected to the side of the electric control actuator 202. By using the signal transceiver 203 to receive the instructions sent by the control terminal, the electric control actuator 202 can be automatically controlled, thereby better controlling the flow rate of oxygen in the oxygen chamber and adjusting the valve to achieve the purpose of intelligent flow rate control, avoiding the problem that it is difficult to perform intelligent flow rate control with traditional safety valves, thus improving the practicality of the safety valve. The safety valve of the hyperbaric oxygen chamber automatically adjusts the oxygen pressure in the chamber to ensure it is within a safe range. When the pressure exceeds the safe range, the safety valve will automatically open and release the excess oxygen to maintain the stability of the pressure in the chamber.

[0027] Among them, a pipe sleeve 204 is fixedly connected to the bottom of the valve chamber 201. A conveying pipe 205 is fixedly connected to the inside of the pipe sleeve 204. A flange plate 206 is fixedly connected to the side of the conveying pipe 205. There are two flange plates 206. By using the flow sensor 102 to monitor the oxygen flow rate, the amount of oxygen discharged can be known in real time to ensure that there is always an appropriate amount of therapeutic oxygen in the oxygen chamber. The flow sensor 102 is a detection instrument for detecting flow parameters of media such as liquids and gases and converting them into signals in other forms for output. The flow sensor 102 has many advantages such as small volume, light weight, intuitive and clear reading, high reliability, and no pressure loss.

[0028] In this embodiment, referring to Figure 1 and Figure 4 As shown, the filtering and air-release assembly 3 includes a connecting pipe 301. A flow meter 302 is fixedly connected to the top of the connecting pipe 301. A main pipe 303 is fixedly connected to the side of the connecting pipe 301. A transport pipe 305 is fixedly connected to the side of the main pipe 303. A gas overflow chamber 306 is fixedly connected to the side of the transport pipe 305. An overflow valve 307 is fixedly connected to the bottom of the gas overflow chamber 306. A filter 308 is fixedly connected to the bottom of the main pipe 303. A filter element is provided inside the filter 308. A bent pipe 304 is fixedly connected to the side of the main pipe 303. An air-release exhaust pipe 309 is fixedly connected to the side of the bent pipe 304. The impurity filtering layer, sterilization device and odor purification layer provided inside the filter 308 can better filter the valve, avoiding the problem that most of the automatic control and adjustment valves that are easy to connect are difficult to filter, thus better facilitating the use of the valve.

[0029] In this solution, when using an oxygen chamber safety valve, before installing the high-pressure oxygen chamber safety valve, make sure that the oxygen system has stopped supplying gas and the pressure inside the chamber has dropped to a safe range. Align and insert the exhaust pipe 101 with the delivery pipe 205, and gently press the protruding part with a wrench to fix the safety valve in place. The high-pressure oxygen chamber safety valve automatically adjusts the oxygen pressure inside the chamber to ensure it is within a safe range. When the pressure exceeds the safe range, the safety valve will automatically open and release the excess oxygen to keep the pressure inside the chamber stable. Please check whether the safety valve is working properly before each use of the high-pressure oxygen chamber. If any problems or abnormalities are found, they should be replaced or repaired in a timely manner. Operate the high-pressure oxygen chamber safety valve only under the guidance of professionals. When using or checking the safety valve, make sure that the pressure inside the chamber has dropped to a safe range. Do not stack other objects near the safety valve to avoid blocking its normal operation. Regularly check whether there are problems such as leakage or blockage of the safety valve and carry out maintenance or replacement in a timely manner. Pay attention to the symbols and signs of the valve to ensure correct operation and judgment. In case of an emergency, if the internal pressure of the high-pressure oxygen chamber rises abnormally, stop using it immediately and notify the relevant personnel for repair and handling promptly. By using the signal transceiver 203 to receive the instructions sent by the control terminal, the electric control actuator 202 can be automatically controlled, and thus the flow rate of the oxygen in the oxygen chamber can be better controlled, and the valve can be adjusted to achieve the purpose of intelligent control of the flow rate, and then keep the specified oxygen always present inside the chamber.
