[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] This application discloses a gas purification device for anesthesiology. Please refer to [link / reference]. Figures 1-5A gas purification device for anesthesiology includes: a purification box 1, one end of which is connected to a tracheal connection assembly 4 for introducing anesthetic exhaust gas into the purification box 1; a base plate 2 is fixedly connected to one bottom side of the purification box 1; casters are installed at the bottom ends of the purification box 1 and the base plate 2 for easy movement of the purification box 1 and the base plate 2; an extraction assembly 3 is provided at the top of the base plate 2 for extracting anesthetic exhaust gas from the air; the tracheal connection assembly 4 includes a connecting outer tube 410 communicating with the interior of the purification box 1; a plurality of engaging holes 411 are provided through the outer wall of the connecting outer tube 410; a plurality of reinforcing holes 412 are provided on the outer wall of one end of the connecting outer tube 410; and a connecting inner tube 406 is engaged with the inner wall of the connecting outer tube 410. The internal structure has several small holes, and each hole has a slide rod 407 fixedly connected to its inner wall. A spring 408 is fitted onto the outer wall of each slide rod 407. One end of each spring 408 is fixedly connected to the bottom inner wall of the small hole. A pressing sleeve 409 is slidably connected to the top outer wall of each slide rod 407. The slide rods 407 limit the movement of the springs 408 and pressing sleeves 409, preventing them from shifting during movement and increasing the stability of the pressing sleeve 409. Each pressing sleeve 409 is fixedly connected to the other end of the spring 408 and engages with a locking hole 411. The air tube connection assembly 4 also includes a slide sleeve 403 slidably connected to the outer wall of the inner tube 406. 3. When the sliding sleeve 403 is moved, the inner wall of one end of the sliding sleeve 403 is in contact with the outer wall of the limiting seat 402. At the same time, the screw hole of the limiting seat 402 coincides with that of the sliding sleeve 403. At this time, the limiting seat 402 and the sliding sleeve 403 are threaded together by the fixing screw 404. Several locking rods 405 are fixedly connected to one end of the outer wall of the sliding sleeve 403. Each locking rod 405 is engaged with the reinforcing hole 412. The locking rods 405 at one end of the sliding sleeve 403 are engaged with the reinforcing hole 412 to increase the connection stability between the inner tube 406 and the outer tube 410. The gas pipe connection assembly 4 also includes an exhaust pipe 401 that is connected to the inner wall of the other end of the inner tube 406. The outer wall of the exhaust pipe 401 is fixed. The air tube connection assembly 4 includes a fixed connection to a limiting seat 402, and a sliding sleeve 403 is slidably connected to the outer wall of the limiting seat 402. The air tube connection assembly 4 also includes several fixing screws 404 threaded to the outer wall of the sliding sleeve 403, with the other ends of each fixing screw 404 threaded to the limiting seat 402. When the pressing sleeve 409 is pressed, it directs the pressure from the hand to the spring 408, compressing the spring 408. This causes the pressing sleeve 409 to move towards the bottom end of the small hole in the inner tube 406, thus engaging the inner tube 406 with the outer tube 410.When the pressing sleeve 409 moves to the engaging hole 411, the pressure applied to the head of the pressing sleeve 409 is removed. At this time, the compressed spring 408 begins to rebound, causing the pressing sleeve 409 to move in the opposite direction, thereby engaging and fixing it with the inner wall of the engaging hole 411.

[0025] Please see Figure 1 and Figure 2 The extraction assembly 3 includes an air guide pipe 301 connected to the inner wall of one end of the purification box 1. One end of the air guide pipe 301 is connected to a suction pump 302, which is fixedly connected to the top of the base plate 2. The extraction assembly 3 also includes an extraction pipe 303 connected to the other end of the suction pump 302. Both the air guide pipe 301 and the extraction pipe 303 are flexible hoses, which facilitates the movement of the extraction pipe 303 with the locking sleeve 305, thereby facilitating the adjustment of the extraction height of the extraction head 304. The top end of the extraction pipe 303 is connected to the extraction head 304, which consists of a rigid pipe, a limiting block, and a bucket-shaped suction hood. The bucket-shaped suction hood is connected to the rigid pipe, and the outer wall of the rigid pipe is fixedly connected to the limiting block, which facilitates the positioning of the extraction head 304 at the upper end of the locking sleeve 305. The other end of the rigid pipe is connected to the extraction pipe 303. The extraction assembly 3 also includes... The extraction assembly 3 includes a locking sleeve 305 that engages with the outer wall of the extraction tube 303. One end of the locking sleeve 305 is fixedly connected to a sliding seat 306. The extraction assembly 3 also includes a slide rail 307 that is fixedly and slidably connected to the inner wall of the sliding seat 306. The slide rail 307 is fixedly connected to the purification box 1. Hydraulic rods 308 are fixedly connected to the bottom ends of both sides of the sliding seat 306. The bottom ends of the two hydraulic rods 308 are fixedly connected to the top outer wall of the base plate 2. When a large amount of anesthetic waste gas accumulates above the patient's bed, the hydraulic rods 308 are activated. The output end of the hydraulic rods 308 drives the sliding seat 306 to slide upward on the slide rail 307. The sliding seat 306 drives the locking sleeve 305 to move upward. The locking sleeve 305 drives the extraction tube 303 to move upward. The extraction tube 303 drives the extraction head 304 to move upward, thereby extracting the air above the bed.

[0026] Working principle and usage procedure: Press the pressing sleeve 409. The pressing sleeve 409 applies pressure to the spring 408, causing the pressing sleeve 409 to enter the small hole of the inner connecting tube 406. At this time, align the inner wall of the inner connecting tube 406 with the inner wall of the outer connecting tube 410, and snap the inner connecting tube 406 into the inner wall of the outer connecting tube 410. When the inner connecting tube 406 and the outer connecting tube 410 are snapped into place, the pressing sleeve 409 moves to the position of the engagement hole 411. Under the elastic force of the spring 408, the inner wall of the pressing sleeve 409 and the engagement hole 411 are engaged. The sliding sleeve 403 is engaged and fixed, so that the engaging rod 405 at one end of the sliding sleeve 403 engages and is fixed with the reinforcing hole 412 at the end of the connecting outer tube 410. Then, the sliding sleeve 403 and the limiting seat 402 are threadedly fixed by the fixing screw 404. When there is some anesthetic waste gas in the air, the air pump 302 is started, so that the anesthetic waste gas in the air enters the extraction head 304. Then, the anesthetic waste gas is introduced into the extraction tube 303 through the extraction head 304, and then the waste gas is introduced into the purification box 1 for purification through the air guide tube 301.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
