Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to an anorectal dressing stick. Background Technology
[0002] When treating anal diseases such as hemorrhoids, anal fistulas, and anal fissures, proctologists often manually fold gauze dressings to compress and support the wound. However, due to the lack of an air passage, this method is not conducive to intestinal gas expulsion, and patients are prone to abdominal distension and discomfort. Furthermore, after packing the dressing, it is mostly fixed with wide adhesive tape, which does not adhere tightly to the buttock tissue. In actual clinical application, this method is cumbersome, the dressing is not firmly attached, and it is easy to loosen and shift, resulting in poor patient comfort and affecting the treatment effect.
[0003] However, in patient treatment, medication is usually administered manually by doctors. This method requires doctors to wear sterile gloves, which is cumbersome. Furthermore, because it's a manual procedure, it demands a certain level of skill and experience; if the pressure applied is not carefully controlled, it can increase patient discomfort. Therefore, a rectal dressing stick has been developed to address these issues. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anorectal dressing stick. The technical problem to be solved by the present invention is that when patients need to be given medication after leaving the hospital, the operator's experience is required. When the medication force is not well controlled, it will increase the patient's pain.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a rectal dressing stick, comprising a shell assembly, an injection assembly disposed in the inner cavity of the shell assembly, and a decompression assembly disposed in the inner cavity of the injection assembly;
[0006] The outer casing assembly includes an outer casing body, a discharge shell fixedly connected to one side of the outer casing body, a top shell fixedly connected to the side of the discharge shell away from the outer casing body, a first fixing plate fixedly connected to the side of the outer casing body away from the discharge shell, a plurality of arc-shaped openings on the outer surface of the first fixing plate, through holes in the inner cavities of the outer casing body, the discharge shell and the first fixing plate, a plurality of mounting holes in the surface of the first fixing plate away from the outer casing body, a mounting base fixedly connected to the inner cavity of the mounting holes, and a pull rope fixedly connected to one side of the mounting base.
[0007] In a preferred embodiment, the injection assembly includes a needle post disposed within a through hole. An outer post is fixedly connected to one side of the needle post, and a second fixing plate is fixedly connected to the side of the outer post away from the needle post. The inner wall of the second fixing plate has a threaded groove, and the inner cavities of the needle post and the outer post have movable cavities.
[0008] In a preferred embodiment, the pressure-reducing assembly includes a toothed turntable disposed on the outside of the second fixed plate. A rotating block is fixedly connected to one side of the toothed turntable. A threaded strip is provided at the intersection of the rotating block and the threaded groove. A connecting rod is fixedly connected to the side of the rotating block away from the toothed turntable. A rubber plug is fixedly connected to the side of the connecting rod away from the rotating block.
[0009] In a preferred embodiment, the pull rope is made of a soft material, the surface of the discharge shell is provided with a plurality of discharge holes, the arc-shaped opening is located on both sides of the first fixing plate, and the arc shape fits the patient's buttock crease.
[0010] In a preferred embodiment, after the housing assembly is connected to the injection assembly, the outer post is disposed outside the first fixing plate.
[0011] In a preferred embodiment, the connecting rod is of the same length after being connected to the needle post, the outer post, and the second fixing plate, and the rubber plug at one end of the connecting rod intersects with the side of the needle post away from the outer post.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model, by comprising a shell assembly, an injection assembly, and a decompression assembly, allows for direct insertion of the shell body into the area requiring dressing during later use. The injection and decompression assemblies are then inserted into the shell assembly. Before insertion, ensure the dispensing shell contains the dressing to be applied. The operator first loops the pull cord around their finger, then presses the injection and decompression assemblies to expel the dressing through the dispensing shell, allowing it to adhere to the area requiring application. During this process, the arc-shaped opening aligns with the patient's buttock crease, further aiding in the expulsion of the dressing and enhancing the device's versatility.
[0014] 2. This utility model, by comprising a shell assembly, an injection assembly, and a decompression assembly, addresses the issue that after the application of medication, the pressure and resistance between the rubber stopper and the inner wall of the through-hole make removal via traditional methods extremely difficult and likely to cause increased pain for the patient. By rotating a toothed disc to drive a connecting rod, the rubber stopper is retracted, preventing contact between the stopper and the inner wall of the through-hole. This allows the injection assembly and decompression assembly to be easily removed, solving the problem of increased patient discomfort when medication is needed after the patient has left the hospital, which requires a high level of operator experience and is exacerbated by improper administration force.

[0021] 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 protection scope of the present utility model.
[0022] This utility model provides an anorectal dressing stick, including a shell assembly 1, an injection assembly 2 disposed in the inner cavity of the shell assembly 1, and a pressure reducing assembly 3 disposed in the inner cavity of the injection assembly 2.
[0023] The outer casing assembly 1 includes an outer casing body 11. A discharge shell 12 is fixedly connected to one side of the outer casing body 11. A top shell 13 is fixedly connected to the side of the discharge shell 12 away from the outer casing body 11. A first fixing plate 14 is fixedly connected to the side of the outer casing body 11 away from the discharge shell 12. Multiple arc-shaped openings 15 are provided on the outer surface of the first fixing plate 14. Through holes 16 are provided in the inner cavities of the outer casing body 11, the discharge shell 12 and the first fixing plate 14. Multiple mounting holes 17 are provided on the surface of the first fixing plate 14 away from the outer casing body 11. A mounting base 18 is fixedly connected to the inner cavity of the mounting hole 17. A pull rope 19 is fixedly connected to one side of the mounting base 18.
[0024] The outer shell assembly 1 is characterized in that: an injection assembly 2 is provided in the inner cavity of the outer shell assembly 1, and a pressure reducing assembly 3 is provided in the inner cavity of the injection assembly 2.
[0025] The outer casing assembly 1 includes an outer casing body 11. A discharge shell 12 is fixedly connected to one side of the outer casing body 11. A top shell 13 is fixedly connected to the side of the discharge shell 12 away from the outer casing body 11. A first fixing plate 14 is fixedly connected to the side of the outer casing body 11 away from the discharge shell 12. Multiple arc-shaped openings 15 are provided on the outer surface of the first fixing plate 14. Through holes 16 are provided in the inner cavities of the outer casing body 11, the discharge shell 12 and the first fixing plate 14. Multiple mounting holes 17 are provided on the surface of the first fixing plate 14 away from the outer casing body 11. A mounting base 18 is fixedly connected to the inner cavity of the mounting hole 17. A pull rope 19 is fixedly connected to one side of the mounting base 18.
[0026] The pressure-reducing component 3 includes a toothed turntable 31, which is located on the outside of the second fixed plate 23. A rotating block 32 is fixedly connected to one side of the toothed turntable 31. A threaded strip 33 is provided at the intersection of the rotating block 32 and the threaded groove 24. A connecting rod 34 is fixedly connected to the side of the rotating block 32 away from the toothed turntable 31. A rubber plug 35 is fixedly connected to the side of the connecting rod 34 away from the rotating block 32.
[0027] The pull rope 19 is made of soft material, and the surface of the discharge shell 12 has multiple discharge holes. The arc-shaped opening 15 is located on both sides of the first fixing plate 14, and the arc shape fits the patient's buttock crease. After the medication is administered, since the dressing stick needs to be placed on the patient for a period of time, the arc shape of the arc-shaped opening 15 fits the patient's buttock crease, making the patient more comfortable when the dressing stick is inserted.
[0028] After the outer shell assembly 1 is connected to the injection assembly 2, the outer post 22 is located outside the first fixing plate 14; in later use, the distance between the outer post 22 and the outside of the first fixing plate 14 can provide the user with operating space.
[0029] The connecting rod 34 is connected to the needle column 21, the outer column 22, and the second fixing plate 23 with the same length. The rubber plug 35 at one end of the connecting rod 34 intersects with the side of the needle column 21 away from the outer column 22. When the injection component 2 and the decompression component 3 need to be removed after use, the pressure and resistance between the rubber plug 35 and the inner wall of the through hole 16 can easily cause the patient to suffer more pain. By rotating the toothed turntable 31, the connecting rod 34 is driven to retract the rubber plug 35, so that the rubber plug 35 does not contact the inner wall of the through hole 16, and the injection component 2 and the decompression component 3 can be easily removed.
[0030] Working principle of this utility model:
[0031] In later use, the outer shell 11 is first slowly inserted into the area of the patient requiring dressing. The injection component 2 and the decompression component 3 are then inserted into the outer shell 1. Before insertion, ensure that the dressing to be applied is in the dispensing shell 12. The operator first puts the pull cord 19 on their finger and then presses the injection component 2 and the decompression component 3 to squeeze the dressing out through the dispensing shell 12 and onto the area to be applied. During this process, the arc-shaped opening 15 fits against the patient's buttock crease, which also helps to squeeze the dressing out for use, improving the versatility of the device. After application, due to the pressure and resistance between the rubber stopper 35 and the inner wall of the through hole 16, pulling it out in the traditional way can easily cause the patient more pain. At this time, by rotating the toothed turntable 31 to drive the connecting rod 34 to retract the rubber stopper 35, so that the rubber stopper 35 does not contact the inner wall of the through hole 16. In this way, the injection component 2 and the decompression component 3 can be easily pulled out directly. This solves the problem that when the patient needs to be given medication after leaving the hospital, the operator's experience is required, and the patient's pain will increase when the administration force is not well controlled.
