[specific embodiment]

Below in conjunction with the description of drawings and the specific embodiment this utility model is further specified.

As depicted in figs. 1 and 2:

The anesthetic machine patient circuit locking device of the technical program comprises following parts: loop lock plunger 1, displacement transducer 2, handle 3, loop locking clamp 4, holddown spring 5, fixed mount 6.

Each parts explanation:

Loop lock plunger 1 is installed on patient circuit's part, has groove on the nose circle cylinder, when locking, cooperates with loop locking clamp, plays fixing and locking patient circuit's effect.

Displacement transducer 2 is installed on the anesthetic machine host machine part, presses the shake-up head of front end, can change the open and-shut mode of pick off, and this pick off can be selected normally closed and often open two states, is convenient to the design of related circuit.

Handle 3 is installed on the anesthetic machine host machine part, and this handle design has the function of cam, can drive locking clamp 4 in loop when moving and move up and down, and the two ends of flange is two planes, cooperates with loop locking clamp 4, can realize positioning function.

Locking clamp 4 in loop is installed on the anesthetic machine host machine part, and the upper end has bayonet socket, can insert in the groove on the loop lock plunger 1, plays the fixedly effect in loop.
