Oxygen flow quantity monitoring method and equipment

Abstract

The invention discloses an oxygen flow quantity monitoring method and oxygen flow quantity monitoring equipment. The quantity of the inhaled oxygen of each breath is monitored by an oxygen flow quantity sensor and the like, so the using time of the residual oxygen quantity can be estimated and the oxygen consumption in the whole machine process can be calculated. Due to the adoption of the oxygen quantity monitoring function of the invention and for an emergency transfer breathing machine which supplies oxygen by the own oxygen bottle, the using time of the current oxygen quantity can be estimated, and medical workers can adjust the oxygen concentration according to the result and take other effective measures and can perform effective treatment conveniently. For a breathing machine which supplies oxygen in a centralized way or is used in hospital, after the adoption of the invention, the quantity of the oxygen used by a patient from starting of the breathing machine to shut-down of the breathing machine can be estimated, and expense settlement and cost management are facilitated. The method and the equipment can be widely applied to equipment needing oxygen supply, such as breathing machines, anaesthesia machines and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an oxygen flow monitoring method and equipment. Background technique [0002] For emergency or transfer ventilators, oxygen is used as the driving gas. If there is no oxygen, the machine cannot work normally. Therefore, it is necessary to set the time for evaluating the normal operation of the machine to the current oxygen amount and current oxygen concentration of the oxygen cylinder. In an emergency, if the oxygen The transfer destination has not been reached after use, so manual ventilation can only be used to maintain the patient's breathing; for therapeutic ventilators, some countries and regions have relatively high cost requirements for use, especially for areas with relatively high oxygen production costs. Estimate the amount of oxygen used. [0003] However, at present, there is no ventilator in the prior art that can simultaneously monitor the use time of the oxy...

AI Technical Summary

Problems solved by technology

[0003] However, at present, there is no ventilator in the prior art that can simultaneously monitor the use time of the oxygen cylinder and the cumulative oxygen consumption, and these two performance indicators are two important indicators that medical staff are more concerned about.
