Description

Technical Field

[0001] This utility model relates to a diversion oxygen supply device, belonging to the field of medical device technology. Background Technology

[0002] To improve work efficiency and ensure safe production, we improved the design of the oxygen supply system by distributing a single oxygen source into multiple output ports to meet the needs of different users. This is especially crucial in high-altitude areas where the thin air makes the need for oxygen cylinders particularly urgent. Therefore, designing an efficient and safe oxygen delivery device is essential for ensuring the stability and continuity of the oxygen supply. The device's design fully considers the unique environmental factors of high-altitude areas, such as variations in air pressure and temperature, thus setting higher standards for equipment durability and reliability. Utility Model Content

[0003] The purpose of this invention is to overcome the problems existing in the prior art and provide a diversion oxygen supply device that is suitable for scenarios with large gas consumption. The method of distributing a single oxygen source into multiple delivery ports not only reduces the cost of use but also improves the safety and hygiene of use.

[0004] To solve the above technical problems, this utility model proposes a diversion oxygen supply device, including a housing. An oxygen high-pressure side connector, a pressure reducing valve, and an oxygen diversion manifold are fixed within the housing. The oxygen diversion manifold has at least one diversion manifold inlet and multiple diversion manifold outlets. The inlet of the oxygen high-pressure side connector is connected to an oxygen source pipeline, and the outlet of the oxygen high-pressure side connector is connected to the inlet of the pressure reducing valve. The outlet of the pressure reducing valve is connected to the diversion manifold inlet. Each diversion manifold outlet is connected to the inlet of a corresponding unit controller via an oxygen supply pipe. A diversion manifold inlet sealing connector is installed in the diversion manifold inlet, and a diversion manifold outlet sealing connector is installed in each diversion manifold outlet.

[0005] Furthermore, the housing is also provided with an annular groove for the passage of the gas supply pipe.

[0006] Furthermore, each annular slot corresponds to a diversion exhaust port, and the annular slot and the adjacent diversion exhaust port are coaxial.

[0007] Furthermore, the unit controller is equipped with a differential pressure sensor, which is located between the air inlet and the air outlet of the unit controller.

[0008] Furthermore, three exhaust outlets are provided on each side of the oxygen diversion channel.

[0009] Compared with the prior art, the present invention has achieved the following beneficial effects:

[0010] 1. Using a diverter can reduce the number of times gas cylinders need to be changed, reduce the labor intensity of workers, and save labor costs.

[0011] 2. Centralized management of high-pressure gas can reduce the existence of safety hazards.

[0012] 3. It can save space, make better and more rational use of space, and facilitate gas management. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] This utility model aims to provide a diversion oxygen supply device, including a housing 1. An oxygen high-pressure side connector 2, a pressure reducing valve 3, and an oxygen diversion manifold 5 are fixed within the housing 1. The oxygen diversion manifold 5 has at least one diversion manifold inlet and six diversion manifold outlets. Three diversion exhaust outlets are respectively provided on both sides of the oxygen diversion manifold 5. The inlet of the oxygen high-pressure side connector 2 is connected to an oxygen source pipeline, and the outlet of the oxygen high-pressure side connector 2 is connected to the inlet of the pressure reducing valve 3. The outlet of the pressure reducing valve 3 is connected to the diversion manifold inlet. Each diversion exhaust outlet is connected to the inlet of a corresponding unit controller 9 via an oxygen delivery pipe 7. A diversion manifold inlet sealing connector 4 is installed in the diversion manifold inlet, and a diversion manifold outlet sealing connector 6 is installed in each diversion exhaust outlet.

[0022] The housing 1 is also provided with an annular groove 8 for the passage of the gas supply pipe. Each annular groove 8 corresponds to a diversion outlet, and the annular groove 8 is coaxial with the adjacent diversion outlet.

[0023] The unit controller 9 is equipped with a differential pressure sensor 10, which is located between the air inlet and the air outlet of the unit controller.

[0024] When someone breathes at the outlet of any unit controller, the corresponding differential pressure sensor 10 senses the negative pressure. Oxygen enters the pressure reducing valve 3 through the gas source via the diversion outlet. After being stabilized by the pressure reducing valve 3, it enters the diversion exhaust channel and then enters the unit controller 9 through the diversion outlet and the gas supply pipe. The controller detects the breathing pulse to supply oxygen to the outlet of the unit controller.

[0025] The diversion channel of this invention can simultaneously supply oxygen to each unit controller for breathing, thereby improving oxygen supply efficiency and reducing operating costs.
