The oxygen pipeline input connector, the oxygen gas cylinder input connector, the oxygen regulation assembly, the oxygen output connector and the driving gas output connector are connected on an oxygen channel to form an oxygen conveying system. The laughing air pipeline input connector, the laughing gas cylinder input connector, the laughing air regulation assembly and the laughing air output connector are connected on a laughing air channel to form a laughing air conveying system. All the connectors and the regulation assemblies are installed on the base to form a highly-integrated whole, the regulation assemblies and all the connectors are communicated through channels inside the base, no hose is needed for connection, the problems of misconnection and leakage are avoided, and assembling, debugging and maintenance are convenient and save time.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a highly integrated gas source input processing and flow control device for anesthesia machines. Background technique [0002] In the existing anesthesia machine, the detection and control of the high-pressure input processing at the front end of the gas source and the low-pressure output at the rear end are realized by the following scattered modules connected by joints and hoses: 1) The gas source inlet module, in which oxygen, nitrous oxide and One for air; 2) Pipeline air source pressure detection module; 3) Pressure regulator module, one for each gas source inlet of oxygen, nitrous oxide and air; 4) Electronic flowmeter module, corresponding to each of oxygen, nitrous oxide and air piece. Each module is connected through hoses and joints to form a detection and control system. [0003] The existing detection and control system of this kind has the following defec...

AI Technical Summary

Problems solved by technology

[0004] 1. The gas source inlet modules are scattered and independent, and various joints need to be assembled to connect with other modules, which is inconvenient and time-consuming to assemble, debug and maintain; the back-end gas channel cannot be shared by laughing gas and air, and the material cost is high

[0005] 2. The pipeline air source pressure detection module is connected to the joint of the air source inlet module through a hose. It is time-consuming and laborious to connect the hoses. There is a risk of wrong connection of multiple hoses, and there is a risk of leakage under high pressure. The two modules are separated and independent. Joint debugging, replacement and maintenance bring inconvenience

[0006] 3. The pressure regulating valve module is connected to the joint of the air source inlet module through a hose, and at the same time connected to the joint of the electronic flowmeter module through a hose. There are many hoses, and there is also a risk of wrong connection, and there is a risk of leakage under high pressure. Give the joint Inconvenience for commissioning, replacement and maintenance

[0007] 4. The three-way gas of the electronic flowmeter module is independent, and various joints need to be assembled to connect with other modules, which is inconvenient and time-consuming to assemble, debug and maintain; in addition, the output gas pressure of the electronic flowmeter has no detection

Laughing gas and air fail to share the gas channel, and the cost of materials is high

[0008] 5. Since each module is scattered and independent, the joint ventilation test takes up a lot of space, and the connection steps are cumbersome. After the test is passed, the hose needs to be disassembled and then assembled to the whole machine

Every hose and every joint is a potential leak point. There are many leak points. If there is a leak, it is very difficult to find the leak point, and the stability and reliability of the system are not guaranteed.

[0009] 6. Each module is scattered and independent, and connected with each other by hoses. The number of hoses is large, and it is easy to have wrong connection and leakage problems; during debugging and maintenance, the hoses are very chaotic after disassembly, and the restoration work is very complicated and easy to connect wrongly.

[0010] 7. The gas output is completed by hose connection, poor usability, high professional requirements, high requirements for maintenance personnel, low maintenance efficiency and high maintenance cost
