Positive and negative pressure ventilator

Abstract

The invention discloses a positive and negative pressure ventilator. The positive and negative pressure ventilator comprises a base; the top of the base is fixedly connected to a connection base; thetop of the connection base is fixedly connected to a shell; the top of an installation base is movably connected to a rotary rod through a bearing; and the bottom of the surface of the rotary rod is fixedly connected to a driven gear. Due to matched use of the base, the connection base, the shell, the rotary rod, the driven gear, a clapboard, a transmission rod, a driving gear, a turntable, the installation base, an installation groove, a fixing base, a clamping groove, a support rod, a spring, a connection plate, a clamping block, a pull rod, a ventilator body, a fixing frame, a humidifier, atransparent shell, an air inlet pipe and an air outlet pipe, the problem that the traditional positive and negative pressure ventilator is inconvenient to adjust can be effectively solved; the devicecan flexibly adjust the angle of the ventilator body in a narrow sickbed gap; the relatively convenient use effect can be achieved; simultaneously, the positive and negative pressure ventilator has adetachable function; and thus, the positive and negative pressure ventilator is conveniently overhauled by a maintenance personnel.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a positive and negative pressure ventilator. Background technique [0002] The ventilator is an artificial mechanical ventilation device, which is used to assist or control the patient's spontaneous breathing movement, so as to achieve the function of gas exchange in the lungs, reduce the consumption of the human body, and facilitate the recovery of respiratory function; After exhaling, the total amount of gas that can be exhaled as hard as possible, the vital capacity is closely related to human breathing. Physiological research shows that: all organs, systems, tissues, and cells of the human body are consuming oxygen all the time. In order to work normally, the oxygen supply in the human body is all obtained by the breathing of the lungs. During the breathing process, the lungs not only need to take in oxygen, but also expel the carbon dioxide metabolized in the body to inc...

Problems solved by technology

[0004] The purpose of the present invention is to provide a positive and negative pressure ventilator, which has the advantages of convenient disassembly and adjustment, and solves the problem that the traditional positive and negative pressure ventilators take up a lot of space due to their large volume and the existing positive and negative pressure ventilators. It is not easy to adjust the positio
