referring to fig. 10, the sealing assembly 64 includes two semicircular plates 640 hinged to the inner wall of the branch pipe 60, a first magnet 641 is fixedly embedded in one side of each of the two semicircular plates 640 opposite to each other, the first magnet 641 attracts in the positive direction and the negative direction, a second magnet 642 is fixedly embedded in one side of each of the two semicircular plates 640 opposite to each other, and the first magnet 641 and the second magnet 642 on each of the semicircular plates 640 have different magnetism, so as to generate magnetic attraction.

A first magnet 641, an anode and a cathode are embedded on the two semicircular plates 640; therefore, when the two semicircular plates 640 are in contact with each other, the second magnet 642 on the semicircular plates 640 has opposite magnetism to the first magnet 641 embedded on the semicircular plates themselves.

When the semicircular plate 640 is opened, the semicircular plate 640 rotates around the hinge point by a certain angle, and then the first magnet 641 and the second magnet 642 on the semicircular plate 640 attract each other, thereby ensuring that the semicircular plate 640 is opened and keeping the branch pipe 60 unblocked.

Two linkage rods 643 are fixed on the inner wall of the arc-shaped clamping block 651, the two linkage rods 643 are both of L-shaped structures, three-size magnet 644 is fixed on one side of each linkage rod 643 close to the semicircular plate 640, and the magnetism of each three-size magnet 644 is opposite to that of the corresponding first magnet 641; the magnetic properties of No. three magnet 644 are opposite to those of No. one magnet 641, and the magnetic force of No. three magnet 644 is much greater than that of No. two magnet 642.

In a specific implementation process, in an initial state, the two semicircular plates 640 are mutually adsorbed by the second magnet 642, and the two semicircular plates 640 form a circular structure to seal the branch pipeline 60; when the anesthesia machine 1 sprays the anesthetic gas to the outside, the anesthetic gas is prevented from leaking from the branch duct 60, and the branch duct 60 is sealed by the two semicircular plates 640.

After the patient is anesthetized, anesthetic gas in the breathing tube 2 needs to be collected, at this time, the waste gas absorption tank 61 is inserted into the branch tube 60, the linkage rod 643 inside the waste gas absorption tank 61 squeezes the two semicircular plates 640 inside the branch tube 60, so that the two semicircular plates 640 rotate to open the branch tube 60, and then the air pump 62 absorbs anesthetic gas remaining in the breathing tube 2 into the waste gas absorption airbag 653 inside the waste gas absorption tank 61.

After the exhaust absorption air bag 653 is sealed by the sealing module 66, the exhaust absorption tank 61 is separated from the branch pipe 60, and the linkage 643 is pushed out from the branch pipe 60, and in the moving process, because the magnetic force of the third magnet 644 is far greater than that of the second magnet 642, the linkage 643 drives the semicircular plate 640 to rotate around the hinge point until the two semicircular plates 640 contact with each other, and then the linkage 643 is separated from the semicircular plates 640, so that the exhaust absorption tank 61 can be taken out.

It should be noted that the two semicircular plates 640 rotate in one direction, and that the two semicircular plates 640 can only rotate in the direction of the breathing conduit 2 and cannot rotate in the direction of the fixing frame 63.

Referring to fig. 11, the present invention further provides a clinical anesthetic waste gas extraction method, which comprises the following steps:

s1, operation preparation: firstly, checking equipment in an operating room, confirming normal operation, then starting the anesthesia machine 1, buckling the breathing mask 3 at the mouth and nose of a patient, pushing a sliding shifting block 54 on the outer wall of the auxiliary pipeline 4 by an anesthesia doctor, rotating an arc-shaped auxiliary plate 41 which plays a sealing role on the auxiliary pipeline 4 at the moment, connecting the breathing pipeline 2 with the outside, then introducing anesthesia gas into the breathing mask 3 worn at the mouth and nose of the patient through the breathing pipeline 2, and enabling the patient to enter an unconscious state after the patient inhales the body.

S2, waste gas sealing: the anesthesiologist pulls the sliding pull piece 54 on the outer wall of the auxiliary conduit 4 reversely, so that the breathing conduit 2 on the breathing mask 3 is sealed by the sealing plate 40 and the arc-shaped auxiliary plate 41, and the gas in the breathing conduit 2 cannot diffuse outwards through the breathing mask 3, so that the anesthetic gas in the breathing conduit 2 is isolated.

S3, waste gas collection: the air pump 62 is started, the air pump 62 pumps air, so that the anesthetic waste gas in the breathing tube 2 is pressed into the waste gas absorption air bag 653 inside the waste gas absorption tank 61 by the sealing plate 40 and the two arc-shaped auxiliary plates 41, and then the waste gas absorption air bag 653 is filled with a larger volume until the anesthetic gas in the breathing tube 2 is uniformly collected.

S4, waste gas treatment: the collected anesthetic waste gas is sealed in the waste gas absorption tank 61, then the waste gas absorption tank 61 is quickly detached and placed on a known filtering device for filtering, and then the waste gas absorption tank 61 is installed on the anesthesia machine 1 again for recycling.

The embodiments of the present invention are all preferred embodiments of the present invention, and the scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
