Technical Field
[0001] This utility model relates to the field of anorectal care technology, specifically to an external medication application device for anorectal care. Background Technology
[0002] The proctology department is mainly responsible for the treatment of diseases of the posterior digestive tract and anal region. Anorectal diseases are very common, especially hemorrhoids. Hemorrhoids are caused by venous clusters formed by congestion, dilation and tortuosity of the venous plexus under the rectal mucosa and anal canal skin. In my country, hemorrhoids are the most common anorectal disease. Treatment of hemorrhoids mainly relies on hemorrhoid suppositories and topical medications.
[0003] When administering topical medications for anorectal diseases, the medication needs to be applied to the anus and rectum. Existing anorectal medication delivery devices typically involve inserting a rod-shaped device loaded with medication into the patient's anus, pushing the medication into the rectum, and then withdrawing the device. Furthermore, the medication in the rod is usually administered in divided doses. However, existing manual delivery devices are simple and cannot accurately deliver the correct amount of medication. Therefore, we propose an external medication delivery device for anorectal care. Utility Model Content
[0004] To address the shortcomings of existing manual drug delivery devices, which are simple and unable to accurately deliver medication in precise quantities, this invention provides an external drug delivery device for anorectal care. This device has the advantage of effectively controlling the dosage by rotating an adjusting plate to adjust the distance between the plate and the top of the drug tube, thus solving the problems mentioned in the background art.
[0005] The technical solution of this utility model is implemented as follows: An external medication device for anorectal care includes a sleeve for placing a medication tube, with one end of the medication tube away from its outlet threadedly connected to the inner wall of the sleeve, and side plates symmetrically connected to the outer wall of the sleeve; it also includes a push rod, which is a threaded rod with graduations on its outer wall, and a piston coaxially connected to one end of the push rod, the diameter of which is equal to the inner diameter of the medication tube, and an adjusting plate threadedly connected to the push rod, the length of which is greater than the inner diameter of the medication tube; a limiting plate is also coaxially slidably connected to the push rod, and an indicator arrow is circumferentially arranged on the limiting plate along the push rod, so that when the piston slides inside the medication tube, the limiting plate is located between the adjusting plate and the medication tube.
[0006] Optionally, an internal thread is provided on the inner wall of the sleeve, and an external thread is provided on the outer wall of the end of the tube away from its outlet, with the external thread engaging with the internal thread.
[0007] Optionally, a skirt for limiting movement is provided coaxially at the end of the tube away from its outlet.
[0008] Optionally, a connecting seat is coaxially mounted on the top of the piston, and the bottom of the push rod is threaded into the connecting seat.
[0009] Optionally, a push plate is fixed to the end of the push rod away from the piston, and a flat surface is opened on the side wall of the push rod, with the scale set on the flat surface.
[0010] Optionally, multiple second anti-slip blocks can be provided on the top of the push plate.
[0011] Optionally, multiple first anti-slip blocks may be provided on the top of the side panel.
[0012] Optionally, an annular seat is connected to the adjusting plate, and the annular seat is threadedly connected to the push rod.
[0013] Compared with the prior art, this utility model adjusts the distance between the adjusting plate and the top of the medicine tube by rotating the adjusting plate, and pushes the push rod to move the adjusting plate. The distance moved is the adjustment distance. The limiting plate and the indicator arrow on it can further facilitate the user to read the scale accurately. This utility model not only has a simple structure, but also effectively realizes the precise control of the dosage, which brings great convenience to the user and effectively improves the practicality of the device.

Detailed Implementation
[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. 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 skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Reference Figures 1 to 4 This utility model provides a technical solution: an external medication administration device for anorectal care, including a sleeve 8 for placing a medication tube 12. It should be noted that the treatment medication is sealed inside the medication tube 12 with aluminum foil, and the end of the medication tube 12 away from its outlet 14 is threadedly connected to the inner wall of the sleeve 8. To achieve a stable connection between the sleeve 8 and the medication tube 12, an internal thread 19 is provided on the inner wall of the sleeve 8, and an external thread 7 is provided on the outer wall of the end of the medication tube 12 away from its outlet 14. The external thread 7 mates with the internal thread 19. After installation, to prevent the end of the medication tube 12 from moving into the end of the sleeve 8, during use... Figure 3 As shown, a skirt 18 for limiting is coaxially provided at the end of the medicine tube 12 away from its medicine outlet 14, and aluminum foil is sealed on the skirt 18, which increases the area of the sealing connection and improves the sealing performance.
[0022] This utility model also includes a push rod 1, which is a threaded rod with a scale 2 on its outer wall. A plane 9 is formed on the side wall of the push rod 1, and the scale 2 is set on the plane 9. A piston 17 for pushing the drug is coaxially connected to one end of the push rod 1. Figure 3 As shown, for ease of installation and disassembly during use, a connecting seat 16 is coaxially provided on the top of the piston 17, and the bottom of the push rod 1 is threaded into the connecting seat 16. In actual use, the diameter of the piston 17 is equal to the inner diameter of the medicine tube 12.
[0023] like Figure 1 , 2 As shown, to achieve precise drug dosage delivery, an adjusting plate 5 is threaded onto the push rod 1, and an annular seat 4 is connected to the adjusting plate 5. The annular seat 4 is threaded onto the push rod 1, and the length of the adjusting plate 5 is set to be greater than the inner diameter of the drug tube 12. By rotating the adjusting plate 5, the distance between it and the top of the drug tube 12 is adjusted. The push rod 1 is then pushed to move the adjusting plate 5. The distance moved is the adjustment distance, thereby achieving precise control of the drug dosage.
[0024] like Figure 1 , 3As shown, a limiting plate 10 is also slidably connected to the push rod 1 on the same axis, and an indicator arrow 11 is provided on the limiting plate 10 along the push rod 1 in a circumferential direction, which is helpful for the user to accurately read the scale 2 on the engraved plane 9. When the piston 17 slides in the medicine tube 12, the limiting plate 10 is located between the adjusting plate 5 and the medicine tube 12.
[0025] In summary, this external medication delivery device for anorectal care allows the user to stably push the push rod 1 during use. Side plates 6 are symmetrically connected to the outer wall of the sleeve 8, and a push plate 3 is tightly fastened to the end of the push rod 1 away from the piston 17. The limiting plate 10 is pushed to the skirt 18 of the medication tube 12, and the distance between the adjusting plate 5 and the limiting plate 10 can be adjusted by rotating the adjusting plate 5. The dosage can be precisely adjusted according to the scale 2.
