Embodiment Construction

[0023] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] refer to figure 1 , shows a schematic block diagram of the gas path structure of the comprehensive measuring instrument according to a preferred embodiment of the present invention. Among them, according to the preferred embodiment of the present invention, there are two air source input interfaces - air interface (first air source interface) A and oxygen interface (second air source interface) B, these two interfaces are connected to the corresponding debugging equipment air The source pipeline is used to input the source gas into the comprehensive tester. Specifically, the air interface A is used for inputting an air source, and it is a self-sealing plug-in interface; the oxygen interface B is used for inputting an oxygen source, and it is a self-sealing threaded interface. Preferably, a filter 1 is connected after the air port A, which is used...

Abstract

The invention discloses a comprehensive tester, mainly used for debugging and calibrating various medical devices as anesthesia machines, ventilators, infusion pumps and the like. The comprehensive tester comprises a first gas source interface (A); a second gas source interface (B); a plurality of gas channels while each channel can be opened and closed; a plurality of pressure detectors (7) respectively arranged in the gas channels for detecting the gas pressures in the gas channels; and a plurality of flux detectors (9) respectively arranged in the gas channels for detecting the gas fluxes in the gas channels. The comprehensive tester can provide at least one gas source for test, can provide a plurality of independent gas channels of adjustable pressures and fluxes, and can independently test gas pressure of flux.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to a comprehensive measuring instrument used for debugging and calibration of various medical instruments such as anesthesia machines, ventilators, and infusion pumps. Background technique [0002] Due to the particularity of its application field, medical equipment requires high operation accuracy, and it needs to be precisely debugged and calibrated before leaving the factory and put into use. It is currently widely used in precision medical equipment (such as anesthesia machines, ventilators and infusion Pumps, etc.) debugging and calibration measuring instruments usually only provide a single air source input, after pressure or flow adjustment, and then output through a single specific interface; or only provide flow detection function alone; or only provide pressure detection function alone . However, these measuring devices that only provide a certain detection function or ...
