[0038] Reference Figure 3 , Figure 5 , wherein a clamping groove 501 is provided on the side wall of the clamping seat 5, a disinfection groove 502 is provided on the side wall of the clamping seat 5, and the disinfection groove 502 is communicated with the clamping groove 501, a locking groove 503 is provided on the side wall of the clamping groove 501, a locking block 504 is slidably connected to the inner wall of the locking groove 503, and a locking spring 505 is fixedly connected between the side wall of the locking block 504 and the locking groove 503;

[0039] With the arrangement of the above structure, the laryngoscope is pushed in along the snap-in groove 501. At this time, the side wall of the laryngoscope will squeeze the side wall of the locking block 504, so that the locking block 504 retracts into the locking groove 503. After the laryngoscope is fully pushed in, the laryngoscope will be firmly snapped into the snap-in groove 501 under the rebound action of the locking spring 505, thereby improving the stability of the laryngoscope during snap-in disinfection.

[0040] Reference Figure 4-Figure 6The disinfection mechanism 6 includes a lifting plate 601, which is slidably connected to the inner wall of the disinfection tank 502, and the lifting plate 601 fits the inner wall of the disinfection tank 502. The bottom of the mounting plate 401 is fixedly connected to an air pump 602, and the input end of the air pump 602 is fixedly connected to an air guide tube 603, and the end of the air guide tube 603 away from the air pump 602 is fixedly connected to the bottom of the card seat 5, and the air guide tube 603 is connected to the lifting plate 601 and the disinfection tank 50 2 are connected, an air guide hole 604 is provided on the side wall of the lifting plate 601, and an air jet pipe 605 is fixedly connected to the side wall of one end of the air guide hole 604 close to the disinfection tank 502, a connecting groove 606 is provided inside the clamping seat 5, and the connecting groove 606 is connected to the air guide hole 604, and a limiting block 607 is fixedly connected to the side wall of the clamping seat 5, and the distance from the limiting block 607 to the top of the lifting plate 601 is equal to the distance between the connecting groove 606 and the air guide hole 604;

[0041] It should be noted that a one-way valve is provided in the jet pipe 605, and the one-way valve in the jet pipe 605 can only allow the airflow to be sprayed from the jet pipe 605 into the disinfection tank 502;

[0042] Through the arrangement of the above structure, the air pump 602 is turned on to generate airflow and fill the air into the cavity between the lifting plate 601 and the disinfection tank 502 through the air guide tube 603. As the airflow is continuously filled, the pressure of the airflow in the cavity will continue to increase, thereby pushing the lifting plate 601 to move upward. At this time, the disinfectant level in the disinfection tank 502 will be pulled up with the lifting plate 601, and as the lifting plate 601 moves upward, the sealed cavity of the disinfection tank 502 will also rise. At this time, the disinfectant level in the disinfection tank 502 It will pass over the laryngoscope blade 2. At the same time, the top of the lifting plate 601 will move up to the position in contact with the limit block 607, and the air guide hole 604 will be connected with the connecting groove 606. At this time, the air flow in the cavity will pass through the connecting groove 606 and the air guide hole 604 into the jet tube 605, and under the extrusion effect, the one-way valve in the jet tube 605 will be opened, so that the air flow will be ejected upward from the bottom of the disinfection groove 502, thereby pushing the disinfectant to impact the laryngoscope blade 2, thereby improving the disinfection effect on the laryngoscope blade 2.

[0043] Reference Figure 5 , Figure 6 , wherein a back-spray groove 608 is provided in the clamping seat 5, and the upper and lower ends of the back-spray groove 608 are respectively connected to the upper and lower parts of the inner cavity of the disinfection tank 502, and a blocking rod 609 is inserted into the back-spray groove 608, and the blocking rod 609 passes through the side wall of the clamping seat 5, and the highest end of the back-spray groove 608 is higher than the upper end of the back-spray groove 608;

[0044] Through the arrangement of the above structure, after the disinfection is completed, the air pump 602 is turned off, and the blocking rod 609 is pulled outward, so that the blocking rod 609 contacts the back-spray groove 608 for sealing. At this time, under the gravity of the disinfectant, the lifting plate 601 will be pressed down, and the gravity will not open the one-way valve in the jet pipe 605, and the airflow in the cavity will be squeezed into the back-spray groove 608, and finally sprayed from the upper end of the back-spray groove 608 to the side wall of the laryngoscope blade 2, so that the laryngoscope blade 2 is dried quickly, thereby improving the disinfection efficiency of the laryngoscope blade 2.

[0046] By setting the above structure, the laryngoscope can be clamped and fixed after the inspection position is adjusted, thereby freeing the hands of medical staff and facilitating medical staff to perform other operations, thereby improving the convenience of laryngoscope detection.

[0047] It should be noted that the transmission line 103 at the end of the handle 1 is electrically connected to the display screen 4, so that the patient's throat condition can be displayed on the display screen 4 during the laryngoscopy examination, which is convenient for medical staff to observe.

[0048] Reference Figure 1-Figure 6 In the present invention, when in use, the laryngoscope is pushed in along the clamping groove 501, at which time the side wall of the laryngoscope will squeeze the side wall of the locking block 504, so that the locking block 504 retracts into the locking groove 503. After the laryngoscope is fully pushed in, the laryngoscope will be firmly clamped in the clamping groove 501 under the rebound effect of the locking spring 505, thereby improving the stability of the subsequent laryngoscope clamping during disinfection;

[0049] Then, the air pump 602 is turned on to generate airflow and fill the air into the cavity between the lifting plate 601 and the disinfection tank 502 through the air guide pipe 603. As the airflow is continuously filled, the pressure of the airflow in the cavity will continue to increase, thereby pushing the lifting plate 601 to move upward. At this time, the disinfectant level in the disinfection tank 502 will be pulled up along with the lifting plate 601, and as the lifting plate 601 moves upward, the sealed cavity of the disinfection tank 502 will also rise higher. At this time, the disinfectant level in the disinfection tank 502 will pass over the laryngoscope blade 2. At the same time, the top of the lifting plate 601 will move upward to a position in contact with the limit block 607, and the air guide hole 604 will also be connected to the connecting groove 606. At this time, the airflow in the cavity will be connected to the air guide hole 604 through the connecting groove 606. The disinfectant is then sucked out of the air pipe 605 and the one-way valve in the air pipe 605 is opened under the action of the squeezing action, so that the airflow is ejected upward from the bottom of the disinfection tank 502, thereby pushing the disinfectant to impact the laryngoscope blade 2, thereby improving the disinfection effect on the laryngoscope blade 2; after the disinfection is completed, the air pump 602 is turned off, and the blocking rod 609 is pulled outward, so that the blocking rod 609 contacts the sealing effect of the back-spray groove 608, at this time, under the action of the gravity of the disinfectant, the lifting plate 601 will be pressed down, and the action of the gravity will not open the one-way valve in the air pipe 605, and the airflow in the cavity will be squeezed into the back-spray groove 608, and finally ejected from the upper end of the back-spray groove 608 to the side wall of the laryngoscope blade 2, so that the laryngoscope blade 2 is dried quickly, thereby improving the disinfection efficiency of the laryngoscope blade 2.
