AI Technical Summary

Technical Problem

Existing respiratory simulation devices cannot realistically simulate the expansion and contraction of the chest cavity during human respiration, resulting in low accuracy of wearable physiological monitoring devices.

Method used

A breathing simulation device is used, including a base, a limiting guide assembly, a push plate, a push rod, an eccentric connector and a motor. The motor controls the rotation of the eccentric connector, which drives the push rod to realize the reciprocating motion of the push plate, simulating the rise and fall of the chest cavity. The expansion and contraction amplitude of the chest cavity can be adjusted by an adjuster.

Benefits of technology

It significantly improves the assessment accuracy of wearable physiological monitoring devices, realistically reproduces the dynamic changes in the chest cavity during human respiration, and provides accurate respiratory motion signals.

Abstract

The utility model relates to a breathing simulation device, belongs to the technical field of medicine, and solves the problems that the breathing simulation device in the prior art is insufficient in simulated thoracic cavity contour fluctuation, and expansion and contraction of a thoracic cavity during breathing of a human body are difficult to reappear truly. The device comprises a base, a limiting guide assembly, a push plate, a push rod, an eccentric connector and a motor, wherein the base is arranged in the chest of the dummy; one end of the limiting guide assembly is fixedly connected with the base, and the other end is fixedly connected with the push plate; the push plate is fixedly connected with a chest rib of the dummy; one end of the push rod is connected with the eccentric connector, and the other end is connected with the push plate; the motor is installed on the base, the eccentric connector is connected with an output shaft of the motor, the eccentric connector is controlled by the motor to rotate, and therefore the push plate is driven by the push rod to reciprocate in the direction close to or away from the base. According to the utility model, the thoracic cavity contour fluctuation is directly simulated, the thoracic cavity contour fluctuation effect is obvious, and the dynamic change of the thoracic cavity when a human body breathes is truly reproduced.
