Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a flexible drug delivery device with physical urge to defecate. Background Technology

[0002] Constipation is a common clinical symptom, with a prevalence rate as high as 27% in the population. Currently, rectal administration is the most widely used treatment for constipation in clinical practice. One principle of rectal administration for constipation is to inject medication into the rectum, lubricating and softening the rectal wall while facilitating the expulsion of stool, thereby relieving constipation symptoms. The most typical rectal administration device is an enema, and there is also a honey enema suitable for babies and pregnant women. Common enema formulations come in two types: glycerin-based and mannitol / magnesium sulfate-based. Although the ingredients differ, the principle is essentially the same: utilizing the high concentration of glycerin or sorbitol—that is, the hyperosmotic effect—to soften the stool, stimulate the intestinal wall, and reflexively induce a defecation reflex. Combined with its lubricating effect, this makes bowel movements easier.

[0003] However, relying solely on glycerin suppositories to stimulate the intestinal wall is not very effective. For some patients with intractable constipation, even one suppository is insufficient to relieve constipation. Therefore, glycerin suppositories that provide multiple physical stimuli to the intestinal wall are needed to promote bowel movements. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art.

[0005] This application provides a flexible drug delivery device with physical urge to defecate, including a bottle body for storing liquid medicine and a bottle stem for delivering liquid medicine. The bottle stem is provided with a step, which divides the bottle stem into two sections, including a front stem section and a rear stem section. The front stem section is covered with an adhesive layer. A through groove is provided on the adhesive layer, and the through groove and the outer wall of the front stem section form a groove.

[0006] The inner wall of the channel is irregularly shaped.

[0007] The overlay layer is made of a soft material.

[0008] There is at least one through groove on the rubber coating layer.

[0009] The outer wall of the rubber coating layer has protrusions.

[0010] There is at least one protrusion.

[0011] The protrusion is positioned higher than the through groove.

[0012] A limiting ring is integrally formed at the lower end of the rubber coating layer, wherein the lower end face of the limiting ring is in contact with the step surface.

[0013] A detachable sealing device is installed on the dispensing port of the bottle.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the setting of the rubber layer and the through groove, when the enema is inserted, a part of the rectal wall will be squeezed into the groove formed by the through groove and the outer wall of the front rod. When the front rod moves, the rectal wall will be squeezed by the inner wall of the through groove. Through physical stimulation of the intestinal wall, it can induce the defecation reflex, thereby producing the urge to defecate and promoting defecation.

[0016] 2. The raised structure on the outer wall of the coating layer can stimulate the intestinal wall while clearing feces and inflammatory secretions from the anal sinuses;

[0017] 3. The coating layer is made of a soft material, which can ensure the deformation of the protrusions and grooves, thereby stimulating the intestinal wall without easily scratching it;

[0018] 4. By setting the limiting ring, when the enema is inserted, the outer wall of the anus fits against the limiting ring, which can prevent leakage and also prevent insertion too deep.

[0019] 5. This medication delivery device and the enema are also suitable for honey enema. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. 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.

[0027] The server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0028] Example 1:

[0029] like Figure 1-3 As shown, this application provides a flexible drug delivery device with physical urge to defecate, including a bottle body 1 for storing liquid medicine and a bottle stem 2 for delivering liquid medicine. The bottle stem 2 is provided with a step 3, which divides the bottle stem 2 into two sections, including a front stem section 201 and a rear stem section 202. The front stem section 201 is wrapped with an adhesive layer 5. The adhesive layer 5 is provided with a through groove 4, which forms a groove with the outer wall of the front stem section 201.

[0030] Furthermore, the inner wall of the through groove 4 is set in an irregular shape.

[0031] Furthermore, the overlay layer 5 is made of a soft material.

[0032] Furthermore, at least one through groove 4 is provided on the adhesive layer 5.

[0033] In this embodiment of the application, due to the aforementioned structure, during use, the sealing body 8 is first removed, and then the enema bottle 2 is inserted into the anus. During insertion, a portion of the anorectal wall enters the groove formed by the through groove 4 and the outer wall of the front rod section 201. The inner wall of the through groove 4 is irregularly shaped, such as teardrop, heart, or crescent. At least one through groove 4 is provided on the adhesive layer 5. As the bottle 2 moves, the corresponding parts of the anorectal wall enter the through groove 4 sequentially, and as it moves, the entered portion slides out of the groove. Therefore, the inner wall of the through groove 4 exerts a reaction force on the anorectal wall, effectively physically stimulating the intestinal wall, inducing the defecation reflex, thereby generating the urge to defecate and promoting defecation. During use, the through groove 4 also serves to store feces and inflammatory secretions. When the enema is removed, the feces and inflammatory secretions are carried out of the body.

[0034] Furthermore, the rubber layer 5 wrapped around the front rod section 201 is made of soft material, such as medical-grade thermoplastic elastomer TPE material or silicone rubber material. Soft material is softer in texture, more comfortable to contact with the human body, avoids scratching the intestinal wall, and can ensure the deformation of the through groove 4, thereby ensuring the stimulation function of the through groove 4.

[0035] Example 2:

[0036] like Figure 1-3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a protrusion 6 is provided on the outer wall of the adhesive layer 5; at least one protrusion 6 is provided; the position of the protrusion 6 is higher than that of the through groove 4.

[0037] In this embodiment of the application, due to the aforementioned structure, at least one protrusion 6 is provided on the outer wall of the adhesive layer 5, and the position of the protrusion 6 needs to be higher than the position of the through groove 4. During use, the protrusion 6 first contacts the anorectal wall, massages the intestinal mucosa, stimulates the intestinal wall stretch receptors, promotes glandular secretion, exerts a self-lubricating effect, and can stimulate the defecation reflex. Furthermore, the protrusion 6 is closely fitted to the inside of the anal sinus, which can effectively clean the feces and secretions in the anal sinus. As the bottle rod 2 continues to be inserted, the through groove 4 provides secondary stimulation to the anorectal wall, and the feces and inflammatory secretions cleaned by the protrusion 6 will enter the through groove 4, which plays the role of retaining feces and inflammatory secretions.

[0038] Example 3:

[0039] like Figure 1-3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a limiting ring 7 integrally formed at the lower end of the adhesive layer 5, wherein the lower end surface of the limiting ring 7 is in contact with the surface of the step 3.

[0040] In this embodiment of the application, due to the aforementioned structure, constipated patients may easily insert the enema without knowing the depth. To limit the insertion depth, a limiting ring 7 is provided at the lower end of the adhesive layer 5. When the limiting ring 7 is in contact with the anal wall, the constipated patient knows that further insertion is not possible. Furthermore, since the adhesive layer 5 is a soft material, and the limiting ring 7 is integrally formed with the adhesive layer 5 and is also soft, when the upper end of the limiting ring 7 contacts the anus, the limiting ring 7 deforms under the force of the anal wall to better conform to the anal wall, thereby improving the tightness between the limiting ring 7 and the anal wall and ensuring that the medication is not easily leaked during the use of the enema.

[0041] Example 4:

[0042] like Figure 1-3As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a sealing body 8 is detachably installed on the dispensing port of the bottle stem 2.

[0043] In this embodiment of the application, due to the above-described structure, in order to ensure the sealing of the enema, a sealing body 8 is detachably installed at the dispensing port of the bottle stem 2. Before use, the sealing body 8 needs to be removed. The lower end of the sealing body 8 is the sealing part 801, and the upper end is the removal part 802. The sealing part 801 is interference-fitted with the diameter of the dispensing channel inside the bottle stem 2. The removal part 802 is designed in a three-dimensional shape, such as a heart shape, peach shape, honeycomb shape, etc. The three-dimensional design increases the contact area with the hand, making it easier to remove.
