AI Technical Summary

Technical Problem

In existing technologies, when using a ventilator, it is difficult to maintain a uniform pressure when manually squeezing the spherical air bag, resulting in unstable oxygen flow rate and affecting normal operation when there are few staff members.

Method used

It adopts a positioning adjustment mechanism, an airbag synchronous pressing mechanism, and a pressing force adjustment mechanism. Through motor drive and gear meshing, it realizes automatic positioning and clamping of airbag, synchronous pressing, and pressing force adjustment, avoiding manual operation.

Benefits of technology

It enables automatic adaptive clamping of airbags of different sizes, ensuring the stability of oxygen flow rate, reducing the need for manual operation, and improving the applicability and efficiency of the equipment.

Abstract

The application provides an artificial respirator for pneumology, and belongs to the technical field of artificial respirators. The artificial respirator for pneumology comprises a base and a spherical air bag, the top of the base is provided with a positioning adjusting mechanism, the positioning adjusting mechanism comprises first sliding grooves and adjusting plates, the first sliding grooves are arranged on the top of the base, two first sliding grooves are symmetrically arranged along the central axis of the base, and a bidirectional screw rod is rotationally arranged in one of the first sliding grooves. The positioning adjusting mechanism is arranged, two adjusting plates simultaneously move in opposite directions until two first positioning plates and two second positioning plates are in contact with the outer wall of the spherical air bag, so that the spherical air bag is positioned and clamped, manual holding is not needed, compared with the prior art, whether it is an adult type, a child type or a baby type, the three common specifications can be adaptively clamped, and the application range of the device is improved.
