[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, a medical adhesive applicator includes an insertion tube 1; a corrugated tube 21 is fixedly connected to the front end of the insertion tube 1, a connecting tube 22 is fixedly connected to the front end of the corrugated tube 21, a connecting cap 23 is fixedly connected to the outside of the connecting tube 22, a connecting sleeve 24 is provided on the outside of the front end of the connecting tube 22, an applicator end 25 is fixedly connected to the front end of the connecting sleeve 24, and liquid outlets 26 are provided at both the upper and lower ends of the applicator end 25; a connecting component is provided between the connecting tube 22 and the connecting sleeve 24.

[0024] During operation, firstly, pull the insert tube 1 according to the length of the medical adhesive packaging bottle to extend the corrugated tube 21 to fit the length of the medical adhesive packaging bottle. Then, insert the insert tube 1 and the corrugated tube 21 into the inside of the medical adhesive packaging bottle, and tighten the connecting cap 23 to the bottle opening. When the adhesive needs to be squeezed out for application, squeeze the medical adhesive packaging bottle so that the adhesive enters the inside of the application end 25 through the insert tube 1, the corrugated tube 21 and the connecting tube 22 under the pressure. It is squeezed out to the affected area through the liquid outlet 26 opened on the application end 25. The adhesive is then applied by the shovel-shaped application end 25 so that the adhesive is evenly applied to the surface of the affected area.

[0025] Furthermore, the connecting component includes a positioning block 27, which is fixedly connected to the upper and lower ends of the connecting sleeve 24 near the front end. The positioning block 27 has a first movable groove 28 inside, and a fixing card 29 is inserted inside the first movable groove 28. The upper and lower ends of the rear end of the connecting sleeve 24 are both fixed grooves 30, which engage with the front end of the fixing card 29. A slider 31 is fixedly connected to the inner wall of the first movable groove 28. A sliding groove 32 is opened on the front side of the rear end of the fixing card 29. The sliding groove 32 is slidably connected to the slider 31. A first spring 33 is provided inside the sliding groove 32. The top end of the first spring 33 is fixedly connected to the slider 31, and the bottom end of the first spring 33 is fixedly connected to the inner wall of the sliding groove 32.

[0026] During operation, when installing the applicator 25, first align the rear end of the connecting sleeve 24 with the positioning block 27, then push the applicator 25 to move the connecting sleeve 24 toward the positioning block 27. As the connecting sleeve 24 moves toward the positioning block 27, the outer side of the connecting sleeve 24 presses against the inclined surface on the fixing clip 29, causing the fixing clip 29 to move under the pressure. Simultaneously, the fixing clip 29 presses against the first spring 33, causing the first spring 33 to undergo elastic deformation. When the rear end of the connecting sleeve 24 is in contact with the front end of the positioning block 27, the pressure of the outer side of the connecting sleeve 24 on the fixing clip 29 disappears. At this time, the fixing clip 29 returns to its original position under the restoring force of the first spring 33 and engages with the fixing groove 30. The engaging with the fixing groove 30 fixes the connecting sleeve 24 and the applicator 25.

[0027] Furthermore, a top-moving groove 34 is provided on the rear side of the fixed card 29, a second movable groove 36 is provided on the rear side of the first movable groove 28, a top block 35 is inserted inside the second movable groove 36, a slope is provided on the front end of the top block 35, and the top block 35 fits into the top-moving groove 34. A push plate 38 is fixedly connected to the top of the top block 35, and a strip-shaped anti-slip groove is provided on the top of the push plate 38. A second spring 37 is provided inside the second movable groove 36, the front end of the second spring 37 is fixedly connected to the top block 35, and the rear end of the second spring 37 is fixedly connected to the inner wall of the second movable groove 36.

[0028] During operation, when the applicator tip 25 needs to be removed and replaced, the push plate 38 is pushed to move the fixedly connected top block 35 synchronously, causing the top block 35 to move forward and insert into the push groove 34. When the top block 35 moves forward, it stretches the fixedly connected second spring 37, causing the second spring 37 to undergo elastic deformation. When the top block 35 is inserted into the push groove 34, the top block 35 pushes the fixing clip 29 to move, causing the fixing clip 29 to gradually release from the fixing groove 30. When the fixing clip 29 is completely released from the fixing groove 30, the fixing groove 30 is completely released from the fixing groove 30. When the groove 30 is engaged, pull the applicator end 25 forward to disengage the connecting sleeve 24 from the outside of the connecting tube 22 to remove the applicator end 25. At this time, release the push plate 38 to allow the top block 35 to move back to its original position under the restoring force of the second spring 37, thus avoiding obstruction when installing a new applicator end 25 later. Alternatively, you can pull the fixing clip 29 to release the engagement between the fixing grooves 30 and then pull the applicator end 25 forward to remove it.
