Valve cover

Abstract

The invention provides a valve cover. The cover comprises a cover body and a dismantling mechanism. The cover body comprises cover boards (1) with an integrated structure and two air channels (20) used for sealing a breathing loop (5). The dismantling mechanism is arranged between the two cover boards (1). In the installation state of the valve cover, the dismantling mechanism is driven to dismantle the valve cover from the breathing loop (5). When the valve cover is not installed, the dismantling mechanism is driven to install the valve cover to the breathing loop (5) and the valve cover installed on the breathing loop (5) and the outer surface of the breathing loop (5) are located on the same plane. The valve cover has the following beneficial effects: the surface of the valve cover is designed to be aligned with the outer surface of the breathing loop so that space is saved; meanwhile, an assembly method utilizing snap joints helps achieve rapid installation and detachment of the valve cover; inhalation and exhalation valve covers can be designed in an integrated manner so that valve covers can be installed on a conventional breathing loop.

Description

technical field [0001] The invention relates to the technical field of anesthesia machines, in particular to a valve cover. Background technique [0002] The inspiratory valve and the expiratory valve are important parts of the breathing system of an anesthesia machine, and they are two one-way valve structures. When the patient completes the induction of anesthesia, when inhaling, the anesthesia mixture gas enters the patient's body through the opened inspiratory valve, and the expiratory valve closes at this time; The flap is closed, and the gas exhaled by the patient is discharged into the carbon dioxide absorption tank. The inhalation and exhalation valves are set to ensure that the patient inhales fresh gas and exhales excess gas, and prevents the exhaled gas containing carbon dioxide from being inhaled again into the body, thereby avoiding Risk of inhaled low oxygen concentration or high carbon dioxide concentration to the patient. Therefore, the inspiratory valve an...
