Embodiment Construction

[0009] Such as figure 1 As shown, the present invention includes a valve plate, the valve plate includes a cylindrical body 1 with a sealed upper end and an open lower end, and an annular flange with a diameter larger than the diameter of the cylindrical body is provided on the periphery of the lower end opening of the cylindrical body 1 2. A spiral vent 3 is provided on the wall of the cylinder.

[0010] When the present invention is implemented, the overall structure of the valve plate is made of medical rubber, which has sufficient elasticity. When there is no ventilation, the air vent on the valve plate is in a naturally closed state.

[0011] Such as figure 2 Shown, the present invention is installed on a valve seat 4 when in use, when along figure 1 When the direction of the middle arrow is positively ventilated, the airflow pushes the valve plate upwards, the cylinder of the valve plate stretches upwards, the air port 3 is opened, and the air flow passes through the ...

Abstract

The invention relates to a one-way ventilation valve for an anesthesia respirator. The one-way ventilation valve for the anesthesia respirator comprises a valve plate; the valve plate comprises a cylinder body with sealed upper end and opened lower end; an annular flange with a diameter larger than the diameter of the cylinder body is arranged on the peripheral edge of the opened lower end of thecylinder body; and a spiral ventilation port is formed in the cylinder wall of the cylinder body.

Description

technical field [0001] The invention belongs to the technical field of medical equipment manufacturing, and relates to a breathing control part of a medical anesthesia machine, in particular to a one-way ventilation structure for an anesthesia ventilator. Background technique [0002] In the anesthesia breathing system, it is necessary to control the airflow direction of the patient's inhalation and exhalation, and the expiratory channel is closed when inhaling, and vice versa. The traditional implementation method is to set a one-way valve on the ventilation pipe, and set an elastic valve plate at the valve port. The valve plate is made of metal steel sheet or plastic sheet. When the flow is reversed, push down the valve plate to close the valve port, so as to realize the one-way flow of air flow. However, in actual use, due to the moisture contained in the gas, the moisture will condense on the valve plate or the valve port, and the valve plate will stick to the valve por...
