Description

Technical Field

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

[0002] Medical gynecology often requires the injection of medications into the vagina, such as medical gynecological gels. These gels form a protective gel film on the vaginal wall, physically isolating the vaginal wall from external bacteria and thus preventing the colonization of pathogenic microorganisms. The human vagina contains transverse or spiral folds, is rich in blood vessels and nerves, and is sensitive to touch. Furthermore, the vagina connects the uterus and external genitalia, and its overall curvature and angle vary from person to person. Considering these unique physiological characteristics of the vagina, the design of medical gynecological gel injectors (pushers, applicators) should fully consider both safety and comfort.

[0003] However, conventional syringe plungers (propellers, plungers) are shaped like straight syringes and are made of hard medical-grade synthetic polymers such as high-density polyethylene and high-density polypropylene. This means that when inserted into the vagina, the straight plunger cannot change its curvature with the direction of the vagina, resulting in poor comfort. Furthermore, when a conventional syringe plunger (propeller, plunger) enters the vagina, its large tip can easily exert force against the vaginal wall, causing discomfort to the patient and potentially damaging the vaginal wall in severe cases, thus reducing its safety. Utility Model Content

[0004] The purpose of this invention is to provide a novel medical gynecological drug delivery device, the part of which is inserted into the vagina is ergonomically designed and has good flexibility and resilience, which can avoid discomfort and vaginal damage during insertion and use, thereby solving the problems of poor comfort and low safety of conventional injection devices.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a medical gynecological drug delivery device, comprising an insertion part into the vagina and a drug delivery part, wherein:

[0007] The vaginal insertion portion has an overall curved arc and can adapt to bending under the constraint of the vaginal wall; the head end of the vaginal insertion portion is pointed, and the vaginal insertion portion smoothly transitions from the head end to the tail end; a drug delivery channel is opened inside the vaginal insertion portion, and the two ends of the drug delivery channel pass through the head end and the tail end of the vaginal insertion portion, respectively.

[0008] The drug delivery portion is located at the tail end of the vaginal insertion portion, and the output end of the drug delivery portion is connected to the drug delivery channel; the drug delivery portion can provide medication to the drug delivery channel so that the medication reaches the affected area through the head end of the vaginal insertion portion.

[0009] In some embodiments, the drug delivery channel is a curved channel that curves along the curvature of the insertion portion into the vagina.

[0010] In some embodiments, the drug delivery channel is arranged with a narrowing diameter from the tail end to the head end of the vaginal insertion portion.

[0011] In some embodiments, the drug delivery channel is a long-diameter funnel-shaped channel.

[0012] In some embodiments, the drug delivery portion is a storage sac that can store the drug and deliver the drug to the drug delivery channel by squeezing the storage sac.

[0013] In some embodiments, the output end of the storage sac is provided with an output channel integrally formed with the storage sac, the output channel is disposed within the drug delivery channel, and the output port of the output channel is fixed at the head end outlet of the drug delivery channel.

[0014] In some embodiments, the storage sac is a silicone storage sac, and the vaginal insertion portion is a silicone structure.

[0015] In some embodiments, the storage pouch is integrally formed with the vaginal insertion portion.

[0016] In some embodiments, the medical gynecological drug delivery device further includes a protective cap for inserting onto the outside of the vaginal portion.

[0017] In some embodiments, the protective cap is a cylindrical protective cap, and the vaginal insertion portion can be converted from a curved shape to a straight shape under the constraint of the cylindrical protective cap.

[0018] In some embodiments, the cylindrical protective cap is a medical-grade high-density polyethylene protective cap.

[0019] The present invention achieves the following technical advantages over the prior art:

[0020] The medical gynecological drug delivery device proposed in this utility model has a reasonable structural design that conforms to ergonomics. The vaginal insertion part has an overall curved arc, which allows the arc of the vaginal insertion part to match the backward and upward tilt of the human vagina. At the same time, during the insertion process, the size of the arc of the vaginal insertion part can change with the direction of the vagina, achieving self-adaptive bending. This improves comfort and enhances the self-adaptability of the vaginal insertion part, enabling it to adapt to vaginas with different inclinations or different physiological characteristics.

[0021] In addition, the tip of the vaginal insertion part is designed with a gently curved pointed structure, which facilitates the insertion of the vaginal insertion part into the vagina and its smooth movement within the vagina. At the same time, because the pointed tip is rounded, it can avoid puncturing or abrading the vaginal wall during insertion, thereby further improving the comfort of the vaginal insertion part and enhancing its safety, effectively reducing the patient's discomfort.

[0022] In some of the technical solutions disclosed in this utility model, the drug delivery part adopts a squeeze-type drug delivery storage sac.

[0034] One of the purposes of this invention is to provide a novel medical gynecological drug delivery device, the part of which is inserted into the vagina is ergonomically designed and has good flexibility and resilience, which can avoid discomfort and vaginal damage during insertion and use, thereby solving the problems of poor comfort and low safety of conventional injection devices.

[0035] Another objective of this invention is to provide a medical gynecological medication applicator to solve the problems of inconvenience caused by the use of conventional syringes, which require two hands to operate.

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figure 1As shown, this embodiment provides a medical gynecological drug delivery device 100, including a vaginal insertion portion 1 and a drug delivery portion 2. The vaginal insertion portion 1 has an overall curved arc, with one side convex and the other concave. In use, its front end 11 is inserted into the vagina with the front end facing upwards, allowing the arc of the vaginal insertion portion 1 to match the upward and backward tilt of the vagina. Simultaneously, the vaginal insertion portion 1 is made of a soft and resilient flexible material, enabling it to adapt to the folds and creases of the vaginal wall during insertion, improving comfort and enhancing its adaptability. This allows the vaginal insertion portion 1 to adapt to different angles or physiological characteristics of the vagina. Furthermore, the head end 11 of the vaginal insertion portion 1 is designed with a gently curved pointed structure. The vaginal insertion portion 1 transitions smoothly from the head end 11 to the tail end 12, giving the entire vaginal insertion portion 1 a "banana shape." The pointed head end 11 facilitates the insertion of the vaginal insertion portion 1 into the vagina and allows for smooth movement within the vagina. The pointed structure also prevents punctures or abrasions to the vaginal wall, thereby enhancing both the comfort and safety of the vaginal insertion portion 1 and effectively reducing patient discomfort. An administration channel 13 is provided inside the vaginal insertion portion 1, with its two ends penetrating the head end 11 and tail end 12, respectively. The aforementioned administration portion 2 is located at the tail end 12 of the vaginal insertion portion 1, and its output end communicates with the administration channel 13. After the vaginal insertion portion 1 is fully inserted into the vagina, the administration portion 2 provides medication to the administration channel 13, allowing the medication to reach the affected area via the head end 11. The medications used include, but are not limited to, medical gynecological gels; the administration methods for the administration part 2 include, but are not limited to, syringe injection or pouch injection.

[0039] Some feasible implementation methods, such as Figure 1 As shown, the preferred drug delivery channel 13 is a curved channel that curves along the curve of the vaginal insertion portion 1. At the same time, the drug delivery channel 13 is arranged with a narrowing diameter from the tail end 12 to the head end 11 of the vaginal insertion portion 1. This design can ensure that the drug outlet at the head end 11 of the drug delivery channel 13 can accurately deliver the drug to the affected area. It can also achieve small-dose, multiple cumulative drug delivery, which is beneficial to control the dosage, avoid excessive drug delivery and waste, and improve the reliability of independent operation by the patient.

[0040] Some feasible implementation methods, such as Figure 1 As shown, the preferred drug delivery channel 13 is a long-diameter funnel-shaped channel, so that the outlet of the drug delivery channel 13 is narrower than the inlet located at the tail end 12. In some other embodiments, the drug delivery channel 13 can also be designed as a conical or stepped hole to achieve the narrowing design from the inlet to the outlet.

[0041] In some feasible implementations, the diameter of the drug delivery channel 13 outlet can be 2.5 mm to 3 mm, such as 2.6 mm.

[0042] In some feasible implementations, the size of the vaginal insertion portion 1 can be flexibly adjusted according to clinical needs. If the vaginal insertion portion 1 adopts a uniform columnar structure, its outer diameter can be set to 11mm to 13mm, for example, 12mm.

[0043] In some feasible implementations, the drug delivery portion 2 is preferably a squeeze-type drug delivery storage sac 21, which can store the drug and deliver the drug to the drug delivery channel 13 by squeezing the storage sac 21.

[0044] In some feasible embodiments, the storage sac 21 may be equipped with a cap, and the storage sac 21 has a drug inlet, which is welded or glued to a tube opening. The cap may be hinged or threaded to the tube opening to ensure that the cap can open or close the tube opening of the storage sac 21. When the medication in the storage sac 21 is insufficient or exhausted, the medication can be replenished by opening the cap. After replenishment, closing the cap ensures the airtightness of the storage sac 21. Then, by squeezing the storage sac 21, the medication can be pushed into the drug delivery channel 13, and then administered to the affected area through the drug outlet of the drug delivery channel 13.

[0045] In some feasible implementations, the output end of the storage sac 21 can be directly and sealed to the drug inlet at the tail end 12 of the drug delivery channel 13, with the interior of the storage sac 21 communicating with the drug delivery channel 13. Alternatively, the output end of the storage sac 21 can also be provided with an output channel 22 integrally formed with the storage sac 21. The output channel 22 is disposed within the drug delivery channel 13, penetrates the drug delivery channel 13, and its output port is fixed to the drug outlet at the head end 11 of the drug delivery channel 13. Furthermore, the output port of the output channel 22 is located inside the drug delivery channel 13, preventing the output channel 22 from directly contacting the vagina. By setting a long output channel 22 at the output end of the storage sac 21 and inserting the output channel 22 into the drug delivery channel 13, it can be ensured that the connection between the storage sac 21 and the drug delivery channel 13 is tight, avoiding damage and leakage at the connection between the storage sac 21 and the drug delivery channel 13 when the storage sac 21 is squeezed. The setting of the output channel 22 ensures that even if the drug outlet of the storage sac 21 is separated from the drug delivery channel 13, the output channel 22 is still located in the drug delivery channel 13, thus avoiding drug leakage.

[0046] In some feasible embodiments, the storage sac 21 is a silicone storage sac, and the vaginal insertion portion 1 is a one-piece molded silicone structure. As a preferred embodiment, the silicone storage sac and the vaginal insertion portion 1 are integrally molded, in which case the output channel 22 and the drug delivery channel 13 can be considered as a single channel. Alternatively, the silicone storage sac and the vaginal insertion portion 1 can be molded separately and then assembled. Taking the aforementioned output channel 22 on the silicone storage sac as an example, after the output channel 22 extends into the drug delivery channel 13, the outer wall of the output channel 22 can be bonded and fixed to the inner wall of the drug delivery channel 13.

[0047] In some feasible implementations, to ensure safety of use, it is preferable that both the storage pouch 21 and the vaginal insertion portion 1 are made of medical-grade silicone material.

[0048] The following uses the example of dispensing medical gynecological gel to explain the usage method and operating principle of the above-mentioned medical gynecological dispensing device 100:

[0049] In use, hold the tail end 12 of the vaginal insertion part 1 with the head end 11 facing upwards, and then slowly insert the vaginal insertion part 1 into the vagina. After it is fully inserted, squeeze the storage sac 21 containing a certain amount of gel with one hand, and the gel will reach the affected area through the drug delivery channel 13 to complete the drug delivery. After the drug delivery is completed, hold the tail end 12 of the vaginal insertion part 1 and slowly withdraw the vaginal insertion part 1 to complete the use.

[0050] The specific beneficial effects of the medical gynecological drug delivery device 100 proposed in this plan are as follows:

[0051] (i) Ergonomic design enhances safety and comfort.

[0052] The vaginal insertion part 1 has an overall curved arc, which allows the arc of the vaginal insertion part 1 to match the backward and upward tilt of the human vagina. At the same time, the vaginal insertion part 1 is made of soft and elastic silicone material, which allows the vaginal insertion part 1 to change the size of the arc according to the direction of the vagina during insertion, achieving adaptive bending, improving comfort and enhancing the adaptability of the vaginal insertion part 1, so that the vaginal insertion part 1 can adapt to vaginas with different inclinations or different physiological characteristics.

[0053] In addition, the tip 11 of the vaginal insertion part 1 is designed with a pointed structure with a gentle curve, which makes it easy for the vaginal insertion part 1 to be inserted into the vagina and smoothly pushed into the vagina; at the same time, because the pointed tip is rounded, it can avoid puncturing or abrading the vaginal wall during the insertion process, thereby further improving the comfort of the vaginal insertion part 1 and enhancing the safety of the use of the vaginal insertion part 1, which can effectively reduce the patient's discomfort.

[0054] (II) Material Safety

[0055] Both the vaginal insertion part 1 and the storage sac 21 are made of medical-grade silicone material. The vaginal insertion part 1 is smooth and comfortable, and the tip 11 is rounded to avoid damage to the vagina.

[0056] (III) Easy to use

[0057] Conventional syringes (pumpers, injectors) often require both hands to inject gel, which is inconvenient for patients.

[0058] The drug delivery section 2 proposed in this scheme uses a squeeze-type drug delivery storage sac 21. The drug can be dispensed by squeezing the storage sac 21 with one hand, which is convenient and brings convenience to patients for independent drug delivery.

[0059] (iv) Portability

[0060] The drug delivery device proposed in this solution has a simple structure, is made of lightweight silicone, and is easy to carry.

[0061] In summary, the medical gynecological medication applicator 100 is essentially a medical gynecological medication dispenser. It is ergonomically designed, made of safe and comfortable materials, easy to insert into the vagina, and convenient to squeeze out and release medication, achieving the goals of safe and convenient use, high comfort, and easy operation.

[0062] Example 2

[0063] This embodiment proposes a medical gynecological drug delivery device 100, which, based on Embodiment 1, further includes a protective cap 3 for inserting onto the vaginal portion 1. The protective cap 3 primarily protects the vaginal portion 1 and prevents impurities from entering the drug delivery channel 13 through the dispensing port at the head end 11 and contaminating the medication when the device is not in use. The protective cap 3 enhances the safety and reliability of the medical gynecological drug delivery device 100.

[0064] In some feasible implementations, the protective cover 3 can be a cylindrical silicone cover, in which case the protective cover 3 is elastic and flexible, and after the insert is inserted outside the vaginal portion 1, it can maintain the same curvature as the inserted vaginal portion 1.

[0065] The following uses the example of dispensing medical gynecological gel to explain the usage method and operating principle of the above-mentioned medical gynecological dispensing device 100:

[0066] To use, first remove the vaginal insertion portion 1 from the protective cap 3. Then, hold the tail end 12 of the vaginal insertion portion 1 with the head end 11 facing upwards, and slowly insert the vaginal insertion portion 1 into the vagina. Once fully inserted, squeeze the storage sac 21 containing a certain amount of gel with one hand. This will allow the gel to reach the affected area through the drug delivery channel 13, completing the drug delivery. After drug delivery, hold the tail end 12 of the vaginal insertion portion 1 and slowly withdraw it. After withdrawing the vaginal insertion portion 1, insert it from the head end 11 to the tail end 12 into the protective cap 3. This completes the use.

[0067] By equipping the device with a protective cap 3, the hygiene and safety of the medical gynecological medication applicator 100 are improved, and it is also more convenient to carry.

[0068] Example 3

[0069] This embodiment proposes a medical gynecological drug delivery device 100, which differs from Embodiment 2 only in that the protective cover 3 is a rigid, straight cylindrical protective cover. During the process of inserting the vaginal portion 1 into the inside of the straight cylindrical protective cover, the side wall of the straight cylindrical protective cover exerts a circumferential squeezing force on the vaginal portion 1. This not only allows the vaginal portion 1 to change from a curved shape to a straight shape under the constraint of the straight cylindrical protective cover, but also allows the drug outlet of the drug delivery channel 13 to close due to the squeezing. Compared with Embodiment 2, the straight cylindrical protective cover has a stronger protective effect and a better anti-contamination effect on the drug.

[0070] The cylindrical protective cap is made of materials including, but not limited to, medical-grade high-density polyethylene, similar to the outer tube of a traditional syringe, and will not easily deform.

[0071] The following uses the example of dispensing medical gynecological gel to explain the usage method and operating principle of the above-mentioned medical gynecological dispensing device 100:

[0072] When using, first remove the hand-held vaginal insertion part 1 from the cylindrical protective cover, and the hand-held vaginal insertion part 1 will return to its original position. Figure 1 The natural curvature is shown. Then, hold the tail end 12 of the vaginal insertion part 1 with the head end 11 facing upwards, and slowly insert the vaginal insertion part 1 into the vagina. After insertion, squeeze the storage sac 21 containing a certain amount of gel with one hand, so that the gel can reach the affected area through the drug delivery channel 13, completing the drug delivery. After drug delivery, hold the tail end 12 of the vaginal insertion part 1 and slowly withdraw the vaginal insertion part 1. After withdrawing the vaginal insertion part 1, insert it from the head end 11 to the tail end 12 into the straight cylindrical protective cap, and the use is complete.

[0073] By equipping the device with a straight cylindrical protective cap, not only is the hygiene, safety, and portability of the medical gynecological drug delivery device 100 improved, but the straight cylindrical protective cap is also straight. After the vaginal insertion part 1 is inserted into the cap, the drug delivery channel 13 can be squeezed to close the drug outlet of the drug delivery channel 13 due to the squeeze, thus preventing drug contamination.
