Simulation device for testing reflective oximeter

Abstract

The invention relates to the technical field of oximeters, and discloses a simulation device for testing a reflection-type oximeter, the simulation device comprises a thermal insulation tank and an infusion tube, a liquid storage tank is fixedly mounted in the thermal insulation tank, a liquid inlet is formed in the bottom wall of the liquid storage tank, a liquid outlet is formed in the top wall of the liquid storage tank, one end of the infusion tube is communicated with the liquid inlet, and the other end of the infusion tube is communicated with the liquid outlet. The other end of the liquid conveying pipe is communicated with the liquid outlet; a first piston is mounted in the liquid storage tank in a sliding manner; when the reflective oximeter is tested, only the detection end of the oximeter needs to be attached to the infusion tube, the accuracy of the oximeter is detected by comparing the blood oxygen value detected by the oximeter with the actual blood oxygen value of simulated blood, work of a heart valve of a human body is simulated through cooperation of the first piston and the adjusting disc, and the test accuracy of the reflective oximeter is improved. Intermittent conveying of blood is achieved, the blood vessels of the human body are simulated through the infusion tube, the simulation environment is closer to the human body environment, and the debugged oximeter detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of oximeters, in particular to a simulation device for testing reflective oximeters. Background technique [0002] Oxygen is an important substance to maintain the life activities of the human body. Oxygen deficiency can lead to many diseases, and even endanger human life in severe cases. Blood passes through the alveoli, combines oxygen with deoxygenated hemoglobin to form oxyhemoglobin, and transports it to the capillaries of various tissues of the human body through cardiac contraction and relaxation, releasing oxygen for tissue metabolism, so blood oxygen saturation is a reflection of the human body The key indicator of whether the oxygen supply is normal or not; the transmitting and receiving ends of the optical sensor of the reflective oximeter are arranged on the side of the human body, and the light signal enters the body tissue and then reflects back to the receiving end, when the reflective oximete...
