Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a flexible drug delivery device that delivers drugs bidirectionally. Background Technology

[0002] Rectal administration of lubricating and stimulating medications is a common method for managing constipation; the most typical rectal delivery device is the glycerin suppository. A traditional glycerin suppository consists of a reservoir and an injection tube connected to the reservoir. During use, the injection tube is inserted into the rectum through the anus, the reservoir is squeezed, and the medication enters the rectum through the injection tube opening. This softens the stool, lubricates the rectal wall, and stimulates the mucosa to induce a defecation reflex. However, the injection tube of a traditional glycerin suppository can only deliver the medication into the rectum, but it cannot evenly coat the rectal wall with the medication. Therefore, the area of ​​the medication lubricated on the rectal wall is very limited, and the injection tube opening is easily blocked by stool, resulting in poor lubrication of the rectal wall, especially for patients with intractable constipation. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art.

[0004] This application provides a flexible drug delivery device with bidirectional drug dispensing, including a bottle body, a bottle stem, a drug channel for delivering liquid drug and a drug outlet. A flexible body is sleeved on the front end of the bottle stem, and windows are provided on both sides of the flexible body. Radial liquid outlet holes are provided on the bottle stem, wherein the radial liquid outlet holes are located at the windows.

[0005] The dispensing port is detachably fitted with a sealing plug; the sealing plug includes a blocking section and a pulling section, wherein the blocking section is located inside the dispensing port, and the pulling section is located at the top of the bottle stem, and the side wall of the blocking section seals each radial dispensing hole.

[0006] There should be at least one window on each side.

[0007] At least one radial outlet hole is provided and is located at the upper window.

[0008] The diameter of the drug outlet is smaller than the diameter of the drug channel.

[0009] The flexible body is provided with a tongue, and the lower end face of the tongue and the upper inner surface of the upper window are on the same plane.

[0010] The flexible body has an outward protrusion at its tip, located above the tongue.

[0011] There must be at least one outward-facing protrusion.

[0012] The bottle stem has a recess on its outer wall, with the recess located at the window.

[0013] At least one pit should be set.

[0014] The outer wall of the bottle stem is provided with a constraint component, and the inner wall of the flexible body is provided with an installation groove, wherein the constraint component is adapted to the installation groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. With the setting of the window and radial liquid outlet, if the liquid outlet is blocked by feces when the enema is inserted, the radial liquid outlet can also discharge the medicine to lubricate and stimulate the rectal wall. The window can accommodate residual feces in the anal sinus or anal canal.

[0017] 2. By designing the recess, the overall volume of feces that the window can hold is increased, and when the enema is removed, the recess can bring the contained feces out of the body along with it.

[0018] 3. The flexible body is made of soft materials, which makes it more comfortable to contact with the human body, less likely to abrade the intestinal wall, and can ensure the deformation of the tongue, thus stimulating the intestinal wall more effectively;

[0019] 4. Through the setting of the outward protrusion, the protrusion can enter the anal sinus and fit against the inner wall of the anal sinus, thereby stimulating the anal sinus. When moving, it can also clean up the fecal debris remaining in the anal sinus.

[0020] 5. By setting up the restraint component, the inner wall of the anus is prevented from squeezing the flexible body when the enema is inserted, thus preventing the flexible body from falling off or moving.

[0021] 6. The sealing plug can simultaneously seal both the medicine outlet and the radial liquid outlet, ensuring the sealing performance of the enema.

[0022] 7. This dispensing device is suitable not only for glycerin suppositories but also for honey suppositories. Attached Figure Description

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0035] The server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0036] Example 1:

[0037] like Figure 1-7As shown, this application provides a flexible drug delivery device with bidirectional drug dispensing, including a bottle body 1, a bottle rod 2, a drug channel 3 for delivering liquid drugs and a drug outlet 4. A flexible body 5 is sleeved on the front end of the bottle rod 2. Windows 501 are provided on both sides of the flexible body 5. A radial liquid outlet hole 201 is provided on the bottle rod 2, wherein the radial liquid outlet hole 201 is located at the window 501.

[0038] Furthermore, a sealing plug 6 is detachably installed on the drug outlet 4; the sealing plug 6 includes a blocking section 601 and a blocking section 602, wherein the blocking section 601 is located inside the drug outlet 4, and the blocking section 602 is located at the top of the bottle stem 2, and the side wall of the blocking section 601 seals each radial liquid outlet hole 201.

[0039] Furthermore, at least one window 501 is provided on each side; at least one radial outlet hole 201 is provided and is located at the upper end of the window 501.

[0040] Furthermore, the diameter of the drug outlet 4 is smaller than the diameter of the drug channel 3.

[0041] In this embodiment of the application, due to the aforementioned structure, when using the enema, the sealing plug 6 needs to be removed first, and then the enema is inserted into the anus. The flexible body 5 at the upper end of the bottle 2 first contacts the inner wall of the anus. The flexible body 5 is made of a soft material, which provides greater comfort in contact with the human body. The bottle 2 and the flexible body 5 can be made of drug-compatible materials such as polyethylene and polypropylene. Windows 501 are provided on both sides of the flexible body 5. During movement, the tongue 502 protruding from the outer wall of the flexible body 5 will scrape the residual feces in the anal sinus or anal canal. The scraped residual feces will slide into the window 501, which can effectively... The device is designed to accommodate anal sinuses or residual feces within them. The window 501 design saves on the material cost of the flexible body 5. To increase the accommodating area of ​​the window 501, two vertically arranged windows 501 are provided on each side of the flexible body 5. A radial dispensing hole 201 is provided on the side wall of the dispensing port 4 of the bottle stem 2. Four horizontally arranged radial dispensing holes 201 are provided at each of the windows 501 on both sides. Since the bottle stem 2 can easily be inserted directly into the feces when inserted into the anus, the dispensing port 4 is easily blocked by feces. When the bottle body 1 is squeezed, the liquid can flow out from the radial dispensing holes 201 on the side. (Instruction manual attached) Figure 7 The middle arrow indicates the direction of liquid discharge, preventing the liquid from not flowing out properly. Furthermore, the radial discharge hole 201 is closer to the anal canal and rectal mucosa, which can better ensure that the liquid is evenly coated on the rectal wall, increasing the lubrication area and effect of the rectal wall, effectively stimulating the rectal wall and promoting defecation.

[0042] Furthermore, the diameter of the dispensing port 4 inside the bottle stem 2 is smaller than the diameter of the drug channel 3. This diameter difference design allows the diameter of the liquid flow to decrease when the bottle body 1 is squeezed, increasing the speed of the liquid impact and reducing the possibility of fecal matter clogging the dispensing port 4. To seal the liquid inside the bottle body 1, a removable sealing plug 6 is installed on the dispensing port 4. The sealing plug 6 consists of a sealing section 601 and a sealing section 602. The outer wall of the sealing section 601 can block the radial liquid outlet 201 on the inner wall of the dispensing port 4. Before use, both the dispensing port 4 and the radial liquid outlet 201 should be sealed. The sealing section 602 is located at the top of the bottle stem 2, and its outer diameter is larger than the outer diameter of the flexible body 5. The excess portion makes it easier for the user to squeeze and facilitates disassembly and assembly.

[0043] Example 2:

[0044] like Figure 1-8 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a tongue 502 is provided on the flexible body 5, and the lower end face of the tongue 502 and the upper inner surface of the upper window 501 are on the same plane.

[0045] Furthermore, the top of the flexible body 5 is provided with an outward protrusion 8, which is located above the tongue 502; at least one outward protrusion 8 is provided.

[0046] Furthermore, a recess 202 is provided on the outer wall of the bottle stem 2, wherein the recess 202 is located at the window 501; at least one recess 202 is provided.

[0047] In this embodiment of the application, due to the above-described structure, when the enema is inserted, the rectal wall comes into contact with the tongue 502. Since the tongue 502 is a protruding part of the flexible body 5, it can stimulate the rectal wall, stimulate the intestinal wall stretch receptors, and increase the sensitivity of the defecation reflex. Above the tongue 502, the top of the flexible body 5 is provided with 6-10 evenly distributed outward protrusions 8. The shape of the outward protrusions 8 can be set into various irregular shapes such as clamp, teardrop, and cylinder. When inserted, the outward protrusions 8 will enter the corresponding anal sinus, thereby stimulating each anal sinus. Furthermore, when moving, the outward protrusions 8 can clean the fecal debris remaining in the anal sinus. During the insertion of the bottle stem 2, the feces scraped off by the tongue 502 are accommodated by the window 501. Three recesses 202 are provided on the outer wall of the bottle stem 2 at each window 501. These recesses 202 increase the accommodating area of ​​the window 501. Feces not flushed away radially within the window 501 remain in the recesses 202. When the enema is removed after use, these recesses 202 facilitate the removal of the enema from the body. The recesses 202 are elongated to further increase the volume of feces that can be accommodated, but this shape is not the only option.

[0048] Example 3:

[0049] like Figure 3-4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a constraint member 7 is provided on the outer wall of the bottle stem 2, and an installation groove 503 is provided on the inner wall of the flexible body 5, wherein the constraint member 7 is adapted to the installation groove 503.

[0050] In this embodiment of the application, due to the above-described structure, the flexible body 5 is sleeved on the upper end of the bottle stem 2. When the enema is inserted, the flexible body 5 first contacts the anus, and the inner wall of the anus squeezes the flexible body 5. During the insertion process, the flexible body 5 is prevented from falling off or moving. A constraint component 7 is provided outside the bottle stem 2 and is adapted to the mounting groove 503 inside the flexible body 5. The constraint component 7 effectively plays the role of fixing and limiting, effectively preventing the flexible body 5 from falling off or moving.
