Description

Technical Field

[0001] This utility model belongs to the field of medicine application technology, specifically a delivery-type medicine application device. Background Technology

[0002] Gynecological diseases, including vulvar diseases, vaginal diseases, uterine diseases, fallopian tube diseases, and ovarian diseases, often require vaginal medication in their clinical treatment. During treatment, to facilitate medication administration and ensure medication quality, the medication (such as gel, powder, capsule, etc.) is placed into an applicator, which is then inserted into the vagina. The applicator is then pushed into the vagina using a plunger to complete the medication administration procedure.

[0003] Currently, the medication application process is generally performed by the patient. Before the procedure, the medication needs to be inserted into the delivery tube. Since the outlet end of the delivery tube is open, the medication is easily shaken and spills out during the insertion process (before it is inserted into the vagina), which affects the overall quality of the medication application and still needs improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a delivery-type medicine applicator in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: a delivery device includes a delivery tube and a pushing mechanism, wherein the delivery tube is a cylindrical structure and has a hollow delivery channel, the outlet end of the delivery channel is provided with a ruptureable sealing membrane, and the pushing mechanism is slidably installed in the delivery tube for pushing the drug out from the outlet end of the delivery channel.

[0006] In a preferred embodiment, the ruptureable sealing membrane is made of a pH-sensitive material, and the rupture threshold of the ruptureable sealing membrane is the same as the pH value of the vaginal environment.

[0007] In a preferred embodiment, the pushing mechanism includes a piston and a piston rod, the piston being slidably mounted inside the drug delivery tube, the piston being fitted onto one end of the piston rod, and the other end of the piston rod extending outside the drug delivery tube.

[0008] In a preferred embodiment, the piston rod has a pressing portion protruding from one end opposite to the piston, and the diameter of the pressing portion is larger than the diameter of the drug delivery channel.

[0009] In a preferred embodiment, the end of the pressing part facing away from the piston rod is provided with a finger ring that allows a finger to pass through.

[0010] In a preferred embodiment, the delivery tube is made of a transparent material, and the outer surface of the delivery tube is provided with graduations along its length.

[0011] In a preferred embodiment, the end of the delivery tube facing away from the pressing part is provided with a frustum-shaped portion that is narrower at the front and wider at the back.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: a ruptureable sealing membrane that can be broken after being inserted into the vagina is designed at the dispensing end of the delivery tube. When the delivery tube is inserted into the vagina, under the influence of the weak acid pH in the vagina and the pressure of the pushing mechanism, the ruptureable sealing membrane 7 can rupture on its own, preventing the problem of drug spillage and overflow before insertion into the vagina, thus ensuring the quality of drug delivery and making it worthy of promotion.

[0016] The markings in the diagram are: 1-medication tube, 11-medication channel, 12-frustum, 2-scale, 3-piston rod, 4-pressing part, 5-finger ring, 6-piston, 7-rupture sealing membrane. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] Reference Figure 1-3 An insertable medication applicator includes a medication delivery tube 1 and a pushing mechanism. The medication delivery tube 1 has a cylindrical structure and a hollow medication delivery channel 11. The medication outlet end of the medication delivery channel 11 is provided with a ruptureable sealing membrane 7. The pushing mechanism is slidably installed inside the medication delivery tube 1 and is used to push the medication out from the medication outlet end of the medication delivery channel 11. The ruptureable sealing membrane 7 is made of pH-sensitive material, and the rupture threshold of the ruptureable sealing membrane 7 is the same as the pH value of the vaginal environment (pH value is 4.5~5.5). The ruptureable sealing membrane 7 designed at the medication outlet end of the medication delivery tube 1 can rupture after being inserted into the vagina. When the medication delivery tube 1 is inserted into the vagina, under the influence of the weakly acidic pH of the vagina and the pressure of the pushing mechanism, the ruptureable sealing membrane 7 can rupture on its own, preventing the medication from spilling or overflowing before insertion into the vagina, thus ensuring the quality of medication delivery.

[0019] Among them, the ruptureable sealing membrane 7 can be made of sodium alginate composite film, chitosan film, cellulose acetate-based pH sensitive film, etc. It only needs to be able to melt or respond within a predetermined pH value and have good biocompatibility and low irritation (i.e., it can be inserted into the vagina).

[0020] Furthermore, the insertion mechanism includes a piston 6 and a piston rod 3. The piston 6 is slidably installed inside the drug delivery tube 1. The piston 6 is fitted onto one end of the piston rod 3, and the other end of the piston rod 3 extends outside the drug delivery tube 1. After the drug applicator is inserted into the vagina, the user pushes the piston rod 3 with a little force. The piston rod 3 drives the piston 6 to move. During the movement of the piston 6, the drug is pushed out from the drug outlet end of the drug delivery channel 11, thus completing the automatic drug delivery operation.

[0021] Furthermore, a pressing part 4 is formed by protruding from the end of the piston rod 3 facing away from the piston 6. The diameter of the pressing part 4 is larger than the diameter of the drug delivery channel 11. The pressing part 4 can increase the contact area with the fingers and facilitate the push operation by the user.

[0022] Furthermore, the end of the pressing part 4 facing away from the piston rod 3 is provided with a finger ring 5 that allows a finger to pass through. When applying the medicine, the user can pass their finger (preferably the middle finger) through the finger ring 5, thereby achieving the effect of preventing slippage, reducing the possibility of slippage and falling off, and improving the safety of operation.

[0023] Furthermore, the medicine delivery tube 1 is made of transparent material, and the outer surface of the medicine delivery tube 1 is provided with a scale 2 along its length. The scale 2 allows the user to easily adjust to the desired amount of medicine.

[0024] The drug delivery tube 1 is preferably made of medical-grade plastic.

[0025] Furthermore, the end of the delivery tube 1 facing away from the pressing part 4 is provided with a frustum-shaped part 12 that is narrow at the front and wide at the back. This design makes it easier to insert the delivery tube 1 into the vagina and reduces the risk of injury or scratches.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
