Novel respirator for respiratory medicine department

Abstract

The invention discloses a novel respirator for respiratory medicine department. The respirator structurally comprises an alarm mechanism, a power switch, a shell, a display screen, an adjusting button, an observation window, a tube connector and an oxygen conveying tube. The alarm mechanism is installed on the shell. The alarm mechanism is composed of a transmission chain, a fixed decompression device, a first gear, a sensing device, a power-on device, a slide device, an auxiliary device, a fixed rod, a collision device and a loudspeaker device. The transmission chain is arranged on the frontend face of the fixed decompression device. The fixed decompression device and the transmission chain are of an integrated structure. The first gear is arranged at the top end of the transmission chain. The first gear is in clearance fit with the transmission chain. The sensing device is installed on the left side of the slide device. The bottom of the slide device is fixedly provided with the power-on device. When the respirator fails and oxygen can not be supplied, the respirator can make a sound to warn a user, the user can respond immediately, and the life danger caused by oxygen supply deficiency of the user is avoided.

Description

technical field [0001] The invention is a novel ventilator for respiratory internal medicine, which belongs to the field of ventilators. Background technique [0002] Ventilator is a device that can replace, control or change people's normal physiological breathing, increase pulmonary ventilation, improve respiratory function, reduce respiratory work consumption, and save heart reserve capacity. When infants and young children are complicated with acute respiratory failure, after active Conservative treatment is ineffective, breathing is weakened and sputum is thick and thick, sputum is difficult to expel, airway is blocked or atelectasis occurs, tracheal intubation and ventilator should be considered. The ventilator must have four basic functions, namely, inflate the lungs, inhale The conversion of gas to exhalation, the discharge of alveolar gas and the conversion of exhalation to inhalation are repeated in sequence. Therefore, it must be able to provide the power to trans...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a new type of ventilator for respiratory medicine to solve the problem that when the device fails to supply oxygen due to internal failure, the user cannot know, and the user cannot make a decision. The corresponding scheme has hidden dangers to the safety of users
