Respirator

Abstract

The invention discloses a respirator, and relates to the technical field of medical instruments. The respirator comprises an air exchange main pipe provided with an exhalation discharge port, an oxygen input port and a respiratory gas exchange passage port, wherein one end of the air exchange main pipe is connected with a respiratory bag made of soft rubber, and an adjusting knob for adjusting the air output volume is arranged at the exhalation discharge port; the oxygen input port is provided with a one-way valve; the respiratory gas exchange passage port is arranged between the exhalation discharge port and the oxygen input port; the adjusting knob is provided with five-range scales respectively corresponding to five vent holes for adjusting the air output volume. The respirator disclosed by the invention can be used for solving the problems that as the ventilation volume of exhalation discharge cannot be adjusted according to the autonomous respiration condition of a patient, the oxygen supply concentration is difficult to control and the accumulation of carbon dioxide exhaled by the patient is generated easily, and as the respiratory bag cannot be expanded or contracted with the respiration of the patient, the respiration frequency or respiration intensity of the patient cannot be observed from the respiratory bag.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a respirator which can assist and control respiration for patients clinically. Background technique [0002] Respiration is the first element of life support. In medical services, artificial respiration support is required in many cases. Respirator is currently the most widely used and most convenient artificial respiration support tool. It is a device that can replace, control or A device that changes people's normal physiological respiration, increases lung flux, improves respiratory function, reduces the consumption of breathing work, and saves the heart's reserve capacity. A respirator currently used clinically is generally composed of a ventilation main pipe, an oxygen input port on the main ventilation pipe, an exhalation outlet, and a channel outlet for supplying and exhaling air to the patient with a mask or a tracheal intubation. It consists of a breathing bag o...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a respirator, which can solve the problem that because the ventilation volume of the exhalation outlet is constant, the exhaust volume cannot be adjusted depending on the patient's spontaneous breathing situation, and the oxygen supply or concentration is difficult to control. 1. The gas exhaled by the patient cannot be fully discharged in time, so the exhaled carbon dioxide of the patient is prone to accumulate, and the frequency or strength of the patient's breathing cannot be directly observed from the breathing bag because the breathing bag will not expand or contract with the patient's breathing. question
