Embodiment Construction

[0028] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0029] In various embodiments, physicians can electronically and / or mechanically control the flow of fluids (gases and / or liquids), such as oxygen, nitrous oxide, and air, in modern anesthetic delivery systems. One or more control knobs may be configured to electronically or mechanically control the flow of one or more gases. The anesthesia delivery system may utilize manual controls as the primary control system to control the flow of one or more gases and / or anesthetic agents. In addition, manual control can also be used as a backup for electronic control systems.

[0030] A gas mixture, including one or more gases and / or anesthetics, is delivered to the patient through the main breathing system. The primary breathing system may include any type of breathing system, such as non-rebreather rebreathers, closed rebreathers, and s...

Abstract

The invention discloses a fluid electronic control system and an anaesthesia machine with the control system. The fluid electronic control system comprises a driving valve and an electronic control valve system. The driving valve comprises a piston, a fluid inlet, a first fluid outlet and a second fluid outlet, wherein the piston comprises a first channel and a second channel, the first channel is isolated from the second channel, and the piston can be switched between a first position and a second position under driving of fluid; the fluid inlet is used for leading in fluid to be conveyed, when the piston is switched to be at the first position, the fluid inlet is communicated with the first channel, and when the piston is switched to be at the second position, the fluid inlet is communicated with the second channel; the first fluid outlet is communicated with the first channel and the second fluid outlet is communicated with the second channel. The electronic control valve system drives the fluid to flow to the driving valve so as to drive the piston to be switched between the first position and the second position. The anaesthesia machine has good compatibility.

Description

technical field [0001] The invention relates to an electronic control system for controlling fluid in an anesthesia delivery system, especially a fluid electronic control system for controlling fluid switching transmission between a main breathing system and an auxiliary breathing system, and the fluid electronic control system and an auxiliary common gas outlet anesthesia machine. Background technique [0002] Anesthesia machines must accurately and reliably control patient ventilation. In the existing anesthesia gas delivery system, according to the design characteristics of the internal components of the system, it can be divided into anesthesia machine for adults and anesthesia machine for children, so as to better perform anesthesia operations for different groups of people. However, this will increase the equipment procurement cost of the hospital, and the frequency of use of anesthesia machines dedicated to certain groups of people will be low, and most of the struct...
