Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a drug delivery device for the colorectal anus, including a delivery cylinder 1, a connecting cap 2 threadedly connected to the end of the delivery cylinder 1, a delivery tube 3 fixedly connected to the outer end of the connecting cap 2, a set of delivery holes 4 evenly opened on the delivery tube 3, a connecting head 5 threadedly connected to the outer end of the delivery tube 3, a connecting plate 6 fixedly connected to the outer end of the connecting head 5, a suppository elastic clip 7 fixedly connected to the connecting plate 6, a movable block 8 provided inside the delivery cylinder 1, a piston ring 9 fixedly connected to the outer peripheral side wall of the movable block 8, a push tube 10 fixedly connected to the center of the outer side wall of the movable block 8, a set of inner support plates 11 evenly fixedly connected to the outer peripheral side wall of the push tube 10, and the outer side of the push tube 10... The end is fixedly connected to a pusher plate 12, and the inside of the pusher tube 10 is provided with a pusher mechanism 13 for pushing the suppository. The connecting cap 2 facilitates the assembly of the delivery tube 3 and the delivery cylinder 1, improving sustainable use. The delivery tube 3 and the delivery hole 4 can be inserted into the administration site, and can also deliver liquid drugs evenly, increasing the delivery area and improving the therapeutic effect. The suppository elastic clip 7 facilitates the placement of the suppository, thereby facilitating the delivery of the suppository into place and allowing the drug's efficacy to be fully exerted. The movement of the moving block 8 drives the piston ring 9 to move, thereby pushing out the liquid drug. The inner support plate 11 ensures the stable movement of the moving block 8, the piston ring 9, and the pusher tube 10.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the medication delivery mechanism 13 further includes a push rod 1301 slidably disposed within the delivery tube 10. A push ring 1302 is fixedly connected to the outer end of the push rod 1301, a rubber block 1303 is fixedly connected to the inner end of the push rod 1301, and an inner rod 1304 is fixedly connected to the inner end of the rubber block 1303. The end of the inner rod 1304 passes through the moving block 8, and a linkage ring 1305 is fixedly connected to the inner rod 1304. The diameter of the inner rod 1304 is smaller than the inner diameter of the medication delivery tube 3. By holding the push ring 1302 to push the push rod 1301 to move, the movement of the push rod 1301 drives the rubber block 1303 and the inner rod 1304 to move, thereby pushing the suppository out of the suppository elastic clip 7 and delivering the suppository into place.

[0032] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, the outer peripheral sidewall of the drug delivery tube 1 is further provided with a scale 14, and the drug delivery tube 1 is made of a transparent material; the design of the scale 14 makes it easy for the user to accurately control the amount of drug pushed, and the transparent material of the drug delivery tube 1 allows the user to clearly observe the drug pushing process.

[0033] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, a set of anti-slip grooves are evenly provided on the outer peripheral sidewall of the connecting cap 2, the connecting cap 2 is provided with an internal thread, and the output end of the medicine delivery cylinder 1 is provided with an external thread that matches the internal thread; the anti-slip grooves can improve the friction between the connecting cap 2 and the hand, thereby facilitating the assembly and disassembly of the connecting cap 2 and the medicine delivery cylinder 1.

[0034] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the connector 5 is further provided with anti-slip grooves evenly distributed on its outer periphery, and a round hole is provided at the center of the connecting plate 6; the anti-slip grooves can improve the friction of the connector 5, and the round hole facilitates the insertion of the inner rod 1304, thereby facilitating the push-out of the suppository into the affected area.

[0035] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the push tube 10 is further designed with an internal hollow structure, and the outer wall of the inner support piece 11 is in contact with the inner wall of the drug delivery cylinder 1; this facilitates assembly, and the inner support piece 11 ensures that the push tube 10 operates stably.

[0036] Specifically, when using this colorectal medication delivery device: to deliver suppositories, first push the pusher 12 to move the push tube 10, the moving block 8, and the piston ring 9 to the bottom of the delivery cylinder 1. Then, manually open the suppository elastic clip 7 and insert the suppository into it. Next, hold the delivery cylinder 1 and insert the suppository elastic clip 7 into the patient's anus until it reaches the target depth. Then, hold the push ring 1302 to push the push rod 1301 to move. The movement of the push rod 1301 causes the rubber block 1303 and the inner rod 1304 to move. The movement of the inner rod 1304... The suppository is inserted into the connecting plate 6, thereby squeezing out the suppository from the suppository elastic clip 7. When liquid medication needs to be delivered to the patient's affected area, the connecting head 5 is rotated to remove the connecting plate 6 and the suppository elastic clip 7, allowing the medication delivery cartridge 1 to store liquid medication. Then, the medication delivery cartridge 1 is held and the medication delivery tube 3 is inserted into the patient's anus. The pusher 12 is then pushed to move the push tube 10. The movement of the push tube 10 causes the moving block 8 and the piston ring 9 to move, thereby pushing the liquid medication in the medication delivery cartridge 1 into the medication delivery tube 3 for delivery. At the same time, the medication also flows out through the medication delivery hole 4, increasing the delivery range.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
