Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a rectal suppository delivery device. Background Technology

[0002] Clinically, suppositories are commonly used to treat rectal diseases. Because the anus, the opening of the rectum, is located at the back of the body, rectal medication usually requires assistance from medical staff or family members. This undoubtedly causes discomfort for patients and their families, leading some patients to resist using rectal suppositories. If patients could insert the suppository themselves, this situation would be avoided. Furthermore, during self-administration, they could feel the placement and effectiveness of the medication. Currently, rectal suppositories are typically administered using a disposable finger cot. Lubricant is first applied to the anus, and then the suppository is inserted into the cavity using a finger or applicator.

[0003] Chinese utility model CN211178075U discloses a suppository delivery device, which includes a drug-carrying cartridge for containing a suppository and a pusher for pushing the suppository along the drug-carrying cartridge. The top of the drug-carrying cartridge forms a delivery end that can be inserted into the anus. The top of the delivery end has an open delivery port that can be held by the pushed suppository, and the delivery port is closed when not in use. The suppository delivery device provided by this utility model has an openable and closable delivery port at the top of the delivery end of the drug-carrying cartridge. When the pusher is pushed to administer the suppository, the delivery port is opened by the suppository, releasing the suppository; after the suppository is released, the delivery port closes.

[0004] This utility model of anorectal suppository dispenser solves the problems of medication failure and unhygienic delivery caused by incorrect finger operation, but the following three problems still exist:

[0005] 1. Before administering the medication, lubricant still needs to be applied, which is complicated. In addition, when administering medication at home, the lubricant is usually applied with fingers, which also poses a hygiene problem.

[0006] 2. The delivery device for this rectal suppository is difficult to control the speed at which the suppository is pushed out; if the speed is too fast, it can easily cause discomfort to the patient.

[0007] 3. The handle of the push rod of this rectal suppository applicator is mainly designed for situations where medical staff or family members administer medication to patients. When patients administer the medication themselves, the handle is difficult to grip and does not conform to ergonomics. In particular, it is difficult to pull back the push rod after the medication is administered, which may cause some patients to resist using rectal suppositories for treatment. Utility Model Content

[0008] This invention provides a rectal suppository applicator, aiming to solve the problems of existing rectal suppository applicators, such as the need to apply lubricant with fingers, difficulty in controlling the speed of pushing the suppository, and difficulty in gripping the push rod handle.

[0009] To achieve the above objectives, the technical approach adopted by this utility model to solve its technical problem is as follows:

[0010] Design an anorectal suppository applicator with a lubricating bladder encapsulating lubricant on the inner wall of the administration end, and holes on the separable sidewall of the administration end to allow the lubricant to seep out from the holes after being squeezed; connect the drug-carrying cartridge and the push rod with a buffer component to slow down the speed of pushing the push rod.

[0011] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0012] An anorectal suppository delivery device includes a delivery end with multiple separable sidewalls, a drug-carrying cylinder, and a push rod for pushing the anorectal suppository along the drug-carrying cylinder;

[0013] The right end of the drug delivery end is connected to the left end of the drug-carrying cartridge;

[0014] The inner wall of the separable sidewall is provided with a lubrication bladder containing lubricant.

[0015] Furthermore, the separable sidewall is provided with holes for lubricant to seep out.

[0016] Furthermore, the lubrication sac includes a cavity containing lubricant and a sac body fixing piece connected to the right end of the cavity; the sac body fixing piece is connected between the drug delivery end and the drug delivery cartridge.

[0017] Furthermore, the rectal suppository applicator also includes a buffer component for slowing down the pushing speed of the push rod; the buffer component is connected between the right end of the drug-carrying cartridge and the right end of the push rod.

[0018] Furthermore, a thrust plate is provided on the outer side of the right end of the drug-carrying cylinder, and a baffle is provided on the outer side of the right end of the push rod; the buffer component is connected between the thrust plate and the baffle.

[0019] Furthermore, annular elastic strips are connected between the separable sidewalls; the annular elastic strips and the separable sidewalls form a mesh.

[0020] The beneficial effects of this utility model are as follows: Compared with the prior art, the improvement of this utility model lies in that...

[0021] 1. By providing a lubricating bladder containing lubricant on the inner wall of the drug delivery end and setting holes on the separable side wall of the drug delivery end, the lubricant can be evenly seeped out from the holes after being squeezed, achieving the effect of simple operation, cleanliness and hygiene, and shortening the lubrication time.

[0022] 2. By connecting the drug-carrying cartridge and the push rod with a buffer component, the resistance of compressing the buffer component when the push rod is pushed slows down the pushing speed, avoiding discomfort caused by excessive speed. After the rectal suppository is administered, the rebound force generated by the compressed buffer component helps pull the push rod back. This invention is easy to grip, provides slow administration, and is easy to pull back, facilitating self-administration by patients. It helps protect patient privacy, avoids psychological discomfort caused by others administering medication, reduces patient pain, and increases patients' willingness to use rectal suppositories for treatment.

[0034] The technical solutions in 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 embodiments, not all embodiments. Example 1

[0035] refer to Figure 1This utility model provides a rectal suppository applicator, comprising an administration end 1 with multiple separable sidewalls 11, a drug-carrying cylinder 2, a push rod 3 for pushing the rectal suppository along the inside of the drug-carrying cylinder 2, and a limiting member 5. The right end of the administration end 1 is connected to the left end of the drug-carrying cylinder 2. The limiting member 5 is engaged with the outside of the drug-carrying cylinder 2.

[0036] The administration end 1 has an opening 16 that can be held open by the pushed rectal suppository, and the administration opening 16 is closed when not in use. The cross-section of the administration end 1 decreases from the right end to the left end, and tapers at the left end of the administration end 1, which facilitates the gradual insertion of the administration end 1 into the administration site and reduces the discomfort caused by suppository administration.

[0037] The left end of the separable sidewall 11 is separable, while the right end is connected as one piece.

[0038] The inner wall of the separable sidewall 11 is provided with a lubrication bladder 12 containing lubricant.

[0039] The lubrication capsule 12 includes a capsule cavity 13 containing lubricant and a capsule fixation piece 14 connected to the right end of the capsule cavity 13; the capsule fixation piece 14 is connected between the drug delivery end 1 and the drug delivery cartridge 2.

[0040] refer to Figure 2 The capsule cavity 13 is fitted to the inner wall of the separable sidewall 11. The shell of the capsule cavity 13 should be of appropriate thickness to prevent it from cracking under external pressure, so that lubricant can seep out from the administration port 16 and the hole 15. The capsule fixation piece 14 is relatively thicker than the capsule cavity 13 to ensure that the capsule fixation piece 14 will not break when connected to the administration end 1 and the drug carrier 2.

[0041] The right end of the separable sidewall 11 is connected to the left end of the drug-carrying cartridge 2 via a conventional thread. The capsule fixing piece 14 is located between the separable sidewall 11 and the drug-carrying cartridge 2 and is fixed by the threaded connection.

[0042] If the lubricant capsule shell 12 ruptures, it may enter the rectum. Preferably, it is made of an existing material that can decompose within the rectum, such as the shell of a soft capsule. The lubricant is preferably in gel form and can adhere to the separable sidewall 11 for easy application by the patient.

[0043] Furthermore, the separable sidewall 11 is provided with holes 15 for lubricant to seep out.

[0044] The orifice 15 is preferably set with six or more holes, which facilitates the rapid and uniform dispensing of lubricant after it is pushed by the rectal suppository. It can also prevent the removal of any biological tissue or residual excrement that may be present in the rectum during the withdrawal process after administration, thus avoiding psychological discomfort to the patient.

[0045] The right end of the drug-carrying cartridge 2 is provided with a thrust plate 21. The thrust plate 21 is annular and is sleeved on the outside of the right end of the drug-carrying cartridge 2, and has the same center as the drug-carrying cartridge 2 on the same cross-section.

[0046] The outer surface of the drug delivery cartridge 2 is engraved with graduation lines commonly found in existing technologies, allowing patients to easily adjust the drug delivery depth using the limiting component 5. Depending on the patient's age and the type of suppository, the drug delivery depth varies from 2 to 5 cm.

[0047] Preferably, the length of the administration end 1 should not be less than the length of the matching rectal suppository. The total length of the administration end 1 and the drug-carrying cartridge 2 should also not be too long, just enough to allow for the patient's administration depth. Since the administration site is located at the back of the body, an excessively long administration device will increase the difficulty for the patient to administer the medication themselves.

[0048] refer to Figure 1 The push rod 3 includes a rubber piston, a rod body, a baffle 31, and a pull ring 32. The baffle 31 can be two rectangular pieces or a ring. The rubber piston and rod body are existing technologies and will not be described in detail here. The pull ring 32 is preferably a circular ring with an inner diameter that matches the diameter of an adult's finger, making it convenient to slip a finger into the pull ring 32 during use. Compared to traditional circular handles, it has the advantages of being easy to grip, non-slip, and easy to push and pull.

[0049] Furthermore, a buffer member 4 is connected between the thrust plate 21 and the baffle 31; the buffer member 4 is used to reduce the pushing speed and help pull back the push rod 3.

[0050] For details, please refer to Figure 1 The buffer component 4 is preferably an existing elastic material with self-adhesive backing, which is adhered to the right side of the thrust plate 21. Preferred materials include slow-rebound memory foam (like that used in noise-canceling earplugs) or silicone grip rings for hand rehabilitation. Appropriate elasticity and size are selected to provide resistance when pushing the push rod 3, and to slowly rebound and provide appropriate thrust to help pull the push rod 3 back after pushing stops. The buffer component 4 can be configured as two pieces, upper and lower, or as a ring-shaped piece fitted around the outer ring of the push rod 3. Before the buffer component 4 is compressed to its limit, the baffle 31 is held in place by the thrust plate 21, at which point the rectal suppository is dislodged from the administration port 16. This allows the patient to sense the limit of pushing the push rod 3 when administering the medication themselves.

[0051] The limiting component 5 includes a limiting piece and an elastic pad; the limiting piece and the elastic pad are concentric rings, and the elastic pad is engaged between the limiting piece and the drug cartridge 2. Example 2

[0052] The rest of the structure in this embodiment is the same as in Embodiment 1, except that:

[0053] Annular elastic strips 17 are connected between the separable sidewalls 11, forming a mesh 18 with the separable sidewalls 11. For details, refer to... Figure 3-4The drug delivery end 1 includes four separable sidewalls 11. When the drug delivery port 16 is closed, the separable sidewalls 11 are shaped like flower buds, and longitudinal annular elastic strips 17 are provided between each separable sidewall 11. The annular elastic strips 17 are preferably made of silicone.

[0054] The method of using the rectal suppository applicator of this utility model is as follows:

[0055] Before use, move the limiting component 5 and adjust it to the appropriate position according to the scale line. Then, lock the limiting component 5 onto the outside of the drug cartridge 2 to achieve the appropriate insertion depth.

[0056] Remove the push rod 3 and place the rectal suppository into the drug carrier 2.

[0057] Insert the push rod 3 into the drug-carrying cartridge 2, push the pull ring 32, and push the rectal suppository to the left until it reaches the administration end 1. Stop pushing when the suppository is pushed to the left. The lubrication bladder 12 ruptures under the pressure of the rectal suppository, the separable sidewall 11, and the rubber piston, and the lubricant seeps out from the administration port 16, the hole 15, or the mesh 18. Place the administration end 1 close to the anus for thorough lubrication.

[0058] At this time, the administration port 16 is still closed. Insert the administration end 1 into the anus until the limiting member 5 is locked at the anus. Then, put your finger into the pull ring 32 and push the push rod 3 to compress the buffer member 4, so that the anal suppository moves slowly along the axis of the drug-carrying tube 2 and gradually pushes open the separable side wall 11, so that the administration port 16 opens and the anal suppository enters the rectum through the administration port 16.

[0059] When the baffle 31 is blocked by the thrust plate 21, the tail of the anorectal suppository enters the rectum, stops pushing the push rod 3, the buffer component 4 rebounds, and pulls back the pull ring 32 until the buffer component 4 no longer generates a rebound force. At this time, the administration port 16 closes, the anorectal suppository applicator is removed, the anorectal suppository will remain in the rectum, and the anorectal suppository administration is completed.
