Injection type carbon dioxide regulator for breathing machine

Abstract

The invention relates to an injection type carbon dioxide regulator for a breathing machine, and aims to solve the technical problem of man-machine confrontation easily caused by providing carbon dioxide for a patient under the assistance of the breathing machine clinically in the prior art. According to the technical scheme, the injection type carbon dioxide regulator comprises a barrel, a piston, a hollow shaft push rod and a plurality of clamping strips, a hollow shaft through hole is formed in the middle of the top face of the barrel, clamping grooves for fixing the clamping strips are formed in the positions, located at the two ends of the hollow shaft through hole, of the top face of the barrel, and a trachea cannula connector integrated with the barrel is arranged at the bottom end of the barrel;the piston is arranged in the barrel; the hollow shaft push rod is inserted into the hollow shaft through hole and penetrates through the middle of the piston, the lower end of the hollow shaft push rod is flush with the bottom face of the piston, the top end of the hollow shaft push rod is a respirator connector and exceeds the top face of the barrel, and the clamping strips are evenly arranged on the two sides of the outer wall of the hollow shaft push rod. According to the invention, the volume of the breathing dead space can be adjusted by adjusting the up-and-down movement of the injection piston, so that the reutilization of carbon dioxide is increased.

Description

technical field [0001] The invention belongs to the technical field of emergency medicine, and in particular relates to an injection-type carbon dioxide regulator for a ventilator. Background technique [0002] The partial pressure of carbon dioxide in normal human blood is 40±5mmHg. When the partial pressure of carbon dioxide is lower than the normal value, it is diagnosed as "respiratory alkalosis". Respiratory alkalosis is a common disease in emergency department. Caused by strenuous exercise, crying, severe pain, poisoning, trauma, chest and brain diseases, manifested as dizziness, irritability, dyspnea, numbness of hands and feet, convulsions and other symptoms. [0003] There are many ways to give oxygen clinically, but there is no complete and feasible way to give carbon dioxide. The most commonly used method is to wrap the patient's mouth and nose with a paper tube, increase the dead space of the respiratory tract, and let the exhaled carbon dioxide gas be re-inhaled...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing clinical use of the ventilator to assist the patient to provide carbon dioxide is easy to cause man-machine confrontation and cannot adjust CO 2 The technical problem of ventilation volume, providing an injection carbon dioxide regulator for ventilator
