Anaesthetic mask for clinic anesthesiology department

Abstract

The invention discloses an anaesthetic mask for the clinic anesthesiology department. A mask body is provided with fixing belts, the end, away from the mask body, of the first fixing belt is fixedly connected to one side of a winding box, a storage cavity is formed in the winding box, a vertical central shaft is rotatably installed in the storage cavity, and a coaxial winding wheel is fixedly installed at the outer side of the central shaft; the side, away from the first fixing belt, of the storage box is provided with a long-strip-shaped opening communicated with the storage cavity, the end, away from the mask body, of the second fixing belt penetrates through the long-strip-shaped opening and is fixedly connected to the winding wheel, and a fixing belt adjusting mechanism is arranged between a knob and the winding box. When the anaesthetic mask is in use, the knob can be rotated to drive the winding wheel to rotate and wind the second fixing belt, so that the purpose of reducing the overall length of the fixing belts is achieved, or the second fixing belt is drawn out of the winding box to drive the winding wheel to reversely rotate and release the second fixing belt, so that the purpose of increasing the overall length of the fixing belts is achieved. The anaesthetic mask has the advantage that the length of the fixing belts is conveniently adjusted according to the size of the head of a patient.
