Embodiment Construction

[0024] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.

[0025] Please refer to figure 1 As shown, an anesthesia machine system of the present invention includes an air source supply pipeline 1, a breathing circuit 2, an air supply branch 3 and a control module (not shown in the figure), the air source supply pipeline 1 and the air supply branch 3 The airflow output ends of each are connected with the breathing circuit 2.

[0026] The gas source supply pipeline 1 is used to provide the required gas source for the anesthesia machine, which includes the following three pipelines, namely: an oxygen branch 11 for providing oxygen, a dinitrogen monoxide for providing nitrous oxide gas A nitrogen branch 12 and an air branch 13 for supplyi...

Abstract

The invention discloses an anesthesia machine system, comprising a gas source supply pipeline used for providing a gas source, a breathing circuit connected with a patient, and an air supply branch circuit, wherein a gas flow output end of the gas source supply pipeline and an air flow output end of the air supply branch circuit are respectively connected with the breathing circuit; the breathing circuit is internally provided with a pressure sensor used for measuring air pressure in the breathing circuit when the patient inhales; the air supply branch circuit comprises an air box, a one-way valve and a proportional electromagnetic valve which are sequentially connected by pipes along an air supply direction, wherein the opening degree of the proportional electromagnetic valve is changed according to measurement parameters measured by of the pressure sensor. The opening degree of the proportional electromagnetic valve is continuously changed and is also promoted to be changed by the change of a numerical value of the pressure sensor caused by neonatal tidal volume; anesthesia mixed gas is extruded by the pressure of airflow produced by the air box for the patient to use; the anesthesia machine system is accurate in control and wide in applicable people. The invention also discloses a control method of the anesthesia machine system.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anesthesia machine system and a control method thereof. Background technique [0002] In medical equipment, an anesthesia machine is widely used as an indispensable medical instrument for surgical anesthesia. Its main function is to inhale an appropriate amount of anesthesia mixed gas for surgical patients, and at the same time supply a certain proportion of oxygen to ensure normal breathing. During the process of general anesthesia During the operation, the vital signs of the patient are maintained and monitored to ensure the safe and reliable operation. The performance of the anesthesia machine is directly related to whether the operation can be carried out normally. Therefore, the safety, reliability and accuracy of the equipment have become important indicators to measure the quality of the anesthesia machine. [0003] The tidal volume set by the anesthesia ma...
