Abstract

The invention provides a control change-over valve for an anaesthesia machine, which comprises a valve body, a change-over switch and a control device, wherein the valve body is provided with a valve cavity, an air inlet, a first air outlet and a second air outlet; the change-over switch is arranged in the valve cavity and divides the valve cavity into three parts which are a first part, a second part and a third part, wherein the first part is communicated with the first air outlet, the second part is communicated with the second air outlet, the third part is communicated with the air inlet, the third part is provided with a first valve port and a second valve port which are opposite, the first part is communicated with the third part through the first valve port, the second part is communicated with the third part through the second valve port, and the change-over switch is provided with a valve port sealing part; and the control device is driven by the control air of the anaesthesia machine, and controls the movement of the valve port sealing part in order to seal the first valve port and the second valve port. The control change-over valve for the anaesthesia machine of the invention realizes the change-over of manually-controlled air filling and machine-controlled air filling for the anaesthesia machine, has simple structure and good stability and is simple to install.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a control switching valve for an anesthesia machine. Background technique [0002] Currently, when performing major surgery on a patient, it is necessary to anesthetize the patient. Usually, during the entire anesthesia process, the anesthesiologist needs to switch between manual ventilation and machine-controlled ventilation on the anesthesia machine under different circumstances, and must ensure the safety and reliability of the switch. However, in the prior art, the device for switching between manual ventilation and machine-controlled ventilation has a complicated structure and cumbersome installation. Contents of the invention [0003] The present invention is made in an effort to overcome the above-mentioned defects of the prior art. The purpose of the present invention is to propose a device capable of realizing mutual switching between manual control and machine contr...
