Problems solved by technology

With the prolongation of the use time, its energy consumption continues. Since the parameters of each oxygen source are used differently, the zero point value of the oxygen sensor will drift, resulting in inconsistencies in the control and monitoring of oxygen concentration, which will affect the monitoring of oxygen concentration.

Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0023] Such as figure 1 As shown, the present invention provides an automatic calibration method for the oxygen concentration of a ventilator or anesthesia machine, which is suitable for automatically checking the oxygen concentration when the ventilator or anesthesia machine has been running for a long time, and the automatic calibration process is executed The short time will not affect the control of the current oxygen concentration. At the same time, the display unit will also display the relevant information of the automatic calibration of the oxygen concentration, which can ensure the accuracy of the oxygen concentration detection value during the long-term continuous operation of the ventilator or anesthesia machine. Specifically, it includes the following step:

[0024] Step A: During the w...

Abstract

The invention discloses an oxygen concentration auto-checking method of a respirator or anesthetic apparatus. The method includes the steps: A, after the respirator operates for a certain period of time, a judging unit judges whether check conditions of an oxygen concentration sensor are met or not, and a next step is performed until the conditions are met; B, the respirator automatically checks on oxygen concentration; C, a processing unit detects whether an oxygen concentration detection value is qualified or not; if yes, the oxygen concentration detection valve is recorded, and the automatic check process is complete; if not, an alarm unit sends out an alarm signal. The method has the advantages that after the respirator or anesthetic apparatus operates for a long period of time, oxygen concentration is automatically checked, the process takes short executive time, the control of current oxygen concentration is not affected, the display unit displays information related to automatic check of oxygen concentration, and accuracy of the oxygen concentration detection value when the respirator or anesthetic apparatus continuously operates for a long period of time can be ensured.

Description

technical field [0001] The invention relates to the technical field of oxygen concentration verification of a ventilator or anesthesia machine, in particular to a ventilator or anesthesia machine and an automatic oxygen concentration verification method thereof. Background technique [0002] Respiratory support is one of the most critical means to save the lives of emergency and critically ill patients. The ventilator has become an indispensable device in clinical treatment. It has been widely used clinically to improve the patient's oxygenation and ventilation, reduce the work of breathing, support breathing Circulatory function, and the treatment of respiratory failure. Oxygen concentration is one of the important monitoring parameters of the ventilator, and its accuracy has always attracted much attention. Usually, when the measured oxygen concentration value deviates greatly from the set oxygen concentration value, and an alarm prompt is generated, the manual oxygen con...
