The invention discloses an anesthesia vaporizer, a dial and an anesthesia machine. The dial of the anesthesia evaporator includes: a rotating disk, which defines a chamber with an open bottom, and an opening is formed on a part of the peripheral wall of the rotating disk; a pressing plate, which extends into the chamber through the opening and along the The radial direction of the rotating disk is telescopic; the locking device is arranged at the bottom of the pressing plate and has a first limit portion; and the cover plate is arranged at the bottom of the chamber and formed with a through hole that penetrates up and down The opening, and the inner wall of the through opening is formed with a second limiting portion adapted to cooperate with the first limiting portion. According to the dial of the anesthesia vaporizer of the present invention, when the rotating disk is rotated to a certain position, a certain degree of sealing can be achieved in the anesthesia vaporizer, so that under the sealed condition, the anesthesia vaporizer can carry the anesthetic agent loaded therein together. Shipping without leaking. In addition, the structure is simple and the assembly is convenient.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to an anesthesia vaporizer dial, an anesthesia vaporizer with the same and an anesthesia machine with the anesthesia vaporizer. Background technique [0002] The dial of the anesthesia vaporizer is an important part of the anesthesia vaporizer. The main reasons are as follows: 1. The dial is marked with readings, and the doctor rotates the dial to adjust the concentration of different anesthetic gases; 2. The dial must have a dial lock, that is, the pressing degree Only when the dial is locked, the dial can turn. 3. The dial lock has a spring return function. 4. The dial has a limit function when it rotates to the maximum concentration. [0003] However, the dial structure of the traditional evaporator is complicated at present, the dial lock is inconvenient to press, and the assembly is poor. The dial assembly does not have the functions of zero position limit and transport positio...
