Abstract

The invention discloses a portable medical detection device for oil content of compressed air. The portable medical detection device comprises a PID sensor, a signal amplifier, a controller, a display module, a voltage conversion module and a lithium battery, wherein the lithium battery is used for supplying power to the PID sensor, the signal amplifier, the controller and the display module through the voltage conversion module; the PID sensor is connected with the controller through the signal amplifier; the display module is connected with the controller. The portable medical detection device for oil content of compressed air can solve the problem of complex operation.

Description

technical field [0001] The invention relates to a detection device for the oil content of medical compressed air. Background technique [0002] The medical gas system is also called the life support system. The medical positive pressure compressed air is a kind of gas in the system. The oil content in the gas is an important index to evaluate the quality of the gas product. The oil content is stipulated in GB 50571-2012: ≦0.1㎎ / Nm 3 , the existing determination of gas oil content generally needs to be quantitatively transferred to the absorption liquid or adsorption material in an appropriate way, and then quantitatively determined by analytical equipment. There are no special instruments and equipment to directly measure the oil content of medical compressed air. [0003] Medical compressed air is mainly used for ventilators and anesthesia machines for patient treatment to provide positive pressure air to support patient breathing or surgical anesthesia. It is also involve...
