Oxygen flow control integrated device

Abstract

The invention discloses an oxygen flow control integrated device. The device is suitable for a control system of gas conveying and supplying airflow in the field of respiratory therapy and at least comprises a metal block body (8), and the metal block body (8) is connected with one side end of an air inlet quick connector (4), one side end of an air outlet quick connector (5), one side end of a pressure sensor quick connector (6), one side end of an electromagnetic valve block (2), one side end of a proportional valve block (3) and one side end of a single-pass nylon stud (12); the part, extending into the metal block body, of the air inlet quick connector (4) is communicated with the air inlet end of the part, extending into the metal block body, of the proportional valve block (3); and the air outlet end of the part, extending into the metal block body, of the proportional valve block (3) is communicated with the air inlet end of the part, extending into the metal block body, of theelectromagnetic valve block (2). The device is simple in structure and convenient to use, and has an extremely high commercial value.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to an instrument for respiratory therapy, especially an integrated oxygen flow control device. Background technique [0002] The oxygen flow control integrated devices currently produced on the market are divided into: plate-type integrated valves and pipe-type valves. Composed of connections, the connection angle is 90°, both of which realize the throttling control of the gas flow. [0003] However, there are defects in both designs. The assembly operation of the tubular structure is inconvenient, the structure is complicated and the installation space is wasted, the production and assembly operation is difficult, and it cannot be made into an integrated valve. The plate-type integrated valve is connected vertically at 90°. Oxygen will generate resistance when passing through the vertical airway, and the airway is not smooth, so the integrated valve body is noisy when ...

Problems solved by technology

[0003] However, there are defects in the design of both. The assembly operation of the tubular structure is inconvenient, the structure is complicated and the installation space is wasted, the production and assembly operation is difficult, and it cannot be made into an integrated valve. The plate-type integrated valve is connected vertically at 90°. Oxygen will generate resistance when passing through the vertical airway, and the airway is not smooth, so the integrated valve body is noisy when it is working, and it does not have the function of detecting the pressure of the oxygen inlet inlet

[0004] At present, there is no technical solution that can solve the above technical problems, specifically, there is no integrated oxygen flow control device
