Medical breathing machine for intensive care medicine department

Abstract

The invention discloses a medical breathing machine for the intensive care medicine department. The medical breathing machine comprises a breathing machine body, a first flow sensor, a second flow sensor and a gas flow direction sensor, wherein the breathing machine body at least comprises a draught fan; the first flow sensor is arranged at the air outlet of the draught fan; the draught fan is connected with a breathing mask through a first pipeline; the second flow sensor and the gas flow direction sensor are arranged on the inner side of the breathing mask; the first flow sensor is used for detecting the air output of the draught fan; the second flow sensor is used for detecting the tidal volume exhaled by the user; the gas flow direction sensor is used for detecting a gas flow direction in the breathing mask; and the breathing machine further comprises a main controller, wherein the main controller is used for controlling the first flow sensor to obtain first air output and controlling the second flow sensor to obtain an actual exhaled tidal volume, whether the breathing machine leaks air or not is judged according to the first air output and the actual expired tidal volume, and air leakage compensation is conducted. According to the medical breathing machine for the intensive care medicine department, air leakage detection and compensation can be effectively carried out by aiming at the breathing machine.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a medical ventilator for the department of intensive care medicine. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] According to the ventilation mode, ventilators are mainly divided into two types, constant pressure ventilator and constant volume ventilator. The constant pressure ventilator is a type of ventilator that only has a constant pressure ventilation mode, the...

AI Technical Summary

Problems solved by technology

However, during the use of constant-volume ventilators, the ventilator will leak air due to various reasons (such as incorrect wearing of the mask, damage to the air pipeline, loose mask during use, etc.), and the leak of the ventilator will prevent the user from inhaling. Low tidal volume, hypoxemia

At present, there is no good way to detect and compensate for the air leakage of constant volume ventilators
