Embodiment Construction
[0025] The present invention will be further described now in conjunction with accompanying drawing.
[0026] The invention provides an anesthesia machine circuit unlocking device, such as figure 1 , figure 2 and image 3 As shown, it includes an unlocking button 4, a rotating mechanism and a locking block 12, and the three together constitute an unlocking device for an anesthesia machine circuit. Described release button 4 is connected on the loop handle 17 by spring 5, screw one 3, as Figure 7 As shown, a self-resetting mechanism is formed; when the unlock button 4 is pressed downward, the unlock button 4 compresses the spring 5, and the screw 3 at the end withstands the unlock lever 2, offsetting the locking force of the torsion spring 7, and realizing the unlocking action; When the hand that presses the unlocking button 4 is released, the elastic force of the spring 5 pushes the unlocking button 4 upwards to reset it, the screw 13 breaks away from the unlocking lever ...

The invention belongs to the technical field of medical instruments, and particularly relates to an anaesthesia machine loop unlocking device which comprises an unlocking button, a rotating mechanism, and a locking block; the unlocking button is connected with a loop handle through a spring; the locking block is connected with a loop to serve as a limiting device; the rotating mechanism is connected with a rack; the rotating mechanism comprises hooks, an unlocking rod, a right locking rod, a long locking rod, a left locking rod, a locking seat, and torsional springs; the right lock rod and the left lock rod are respectively provided with the hook; one end of the unlocking rod is connected with one end of the right lock rod; one end of the long locking rod is connected with the other end of the right lock rod; the other end of the long locking rod is connected with one end of the left locking rod; and the right locking rod and the left locking rod are inserted into the locking seat and sleeved with the torsional springs respectively. According to the anaesthesia machine loop unlocking device, a locking mechanism and an unlocking mechanism are effectively combined, so that on one hand, the simplicity and the convenience of operation are improved, and one-key operation is realized.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an unlocking device for an anesthesia machine circuit. Background technique [0002] The circuit is an important part of the anesthesia machine. The gas circuit of the patient circuit mainly provides a closed loop for the anesthetic gas, so that the carbon dioxide in the patient's exhaled gas is absorbed and the remaining gas enters the patient's breathing circuit again to control the patient's anesthesia. depth. When inhaling, the driving gas presses the gas in the skin bag into the patient's lungs; when exhaling, the patient relies on the contraction of the chest muscles to re-discharge the lung gas into the skin bag. The soda lime absorber in the circuit is used to absorb the CO exhaled by the patient 2 gas. In practical application, according to the overall structure of the anesthesia machine, there are different ways to fix the circuit, generally direc...
