Respirator simulation lung device for emergency nursing

Abstract

The invention discloses a respirator simulation lung device for emergency nursing. The respirator simulation lung device is composed of a body, an upper substrate, a bottom substrate, a simulation lung cavity, a scavenging port, a flow sensor, a humidity sensor, a throttle control valve, an atomizing spray head, a DC servo motor, a cam, a belt, a connecting rod, a controller and a capacitive liquid crystal control screen, wherein the capacitive liquid crystal control screen is used for setting respiratory physiological parameters such as inspiratory / expiratory ratio, respiratory frequency, tidal volume and vital capacity by use of inputting of a doctor; the flow sensor is used for detecting the air flow passing through the scavenging port of the simulation lung cavity; the humidity sensor is used for detecting the humidity inside the simulation lung cavity; the controller is triggered to control the throttle control valve, the atomizing spray head and the DC servo motor to move according to the set respiration parameters, the detected flow signal and the humidity signal, thereby the air flow and the humidity. The respirator simulation lung device for emergency nursing well conforms to the human pulmonary respiration physiology, is simple in structure and high in practicability, and has an extremely high application value in occasions such as scientific experimental research, respiration physiology teaching and respiration related product inspection.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a ventilator simulating lung device for emergency care. Background technique [0002] With the rapid development of my country's medical industry, mechanical ventilation is becoming more and more common in my country's medical institutions, and the share of ventilators in medical institutions is growing rapidly. The rescue of critically ill patients has become the top priority of major general hospitals, and the construction of intensive care units (ICU) is also constantly being strengthened. Among them, the high-end ventilators used to rescue and maintain the lives of patients have been widely used in the treatment of critically ill patients, and play an extremely important role in the rescue of critically ill patients. [0003] With people's continuous understanding of respiratory physiology, various intelligent ventilators that meet the physiological requirements of t...
