Description

Technical Field

[0001] This utility model relates to the field of vaginal douche technology, and more specifically, to a modified vaginal douche for IVF-ET. Background Technology

[0002] The IVF-ET (In Vitro Fertilization-Embryo Transfer) vaginal douche is a device specifically designed for use in assisted reproductive technology. In IVF cycles, patients need to use Crinone gel from the start of the transfer. Some patients may experience gel buildup a few days after starting medication, resulting in small clumps of gel, shed vaginal cells, and secretions. These clumps usually need to be cleaned with a vaginal douche.

[0003] When using the existing technology to clean up accumulations in a patient's body, the patient must lie supine with their legs slightly apart. A lubricant (such as a water-soluble lubricant) is then applied to the outside of the irrigator head, which is then inserted into the vagina until the tip of the irrigator head is close to the cervix. The reservoir is then squeezed to allow the cleaning solution to be sprayed evenly through the outlet at the tip of the irrigator head, covering the entire vaginal cavity. Repeated squeezing of the reservoir helps to remove gel accumulations and other secretions.

[0004] In practical use, existing technologies have a smooth surface and only have a water outlet at the tip, making it difficult to thoroughly rinse away gel aggregates in the vagina. This seriously affects the absorption of subsequent medications, potentially impacting embryo implantation and causing miscarriage. Therefore, a modified vaginal irrigator specifically designed for IVF-ET is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides an improved vaginal irrigator specifically for IVF-ET. Through the groove, the irrigating head, and multiple water outlets (three, two, and one) inside the silicone sleeve, the water flow is more uniform, effectively reducing local pressure on the vaginal mucosa, lowering the risk of damage, and preventing incomplete cleaning from affecting subsequent drug absorption.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An improved vaginal douche for IVF-ET includes a reservoir and a connector. One end of the reservoir has a connector, and a douche head is threadedly connected to the outer surface of the connector. The outer surface of the douche head is covered with a silicone sleeve. Multiple protrusions are fixedly connected to the outer surface of the silicone sleeve. Three grooves are formed on the outer surface of the silicone sleeve, and five water outlet holes are evenly formed inside the three grooves.

[0010] Furthermore, the top of the rinsing head is provided with a second water outlet, and a second protrusion is fixedly connected to the top of the rinsing head.

[0011] Furthermore, the total length of the rinsing head is 8.5 cm, the top end is 3 cm long, the diameter of the rinsing head is 1 cm, the body end is 5.5 cm long, the diameter is 0.8 cm and gradually decreases evenly to 0.6 cm at the tail end.

[0012] Furthermore, both the first and second protrusions are hemispherical with a diameter of 0.2 cm, and a soft pad is fitted onto their outer surfaces.

[0013] Furthermore, the depth of the groove is 0.15 cm, and the width decreases from top to bottom, ranging from 0.5 cm to 0.3 cm.

[0014] Furthermore, the reservoir has a capacity of 200 ml and is made of soft plastic material, with an elastic rubber pad attached to its surface.

[0015] Furthermore, the outer surface of the silicone sleeve is provided with multiple water outlet holes three, and each group of water outlet holes three has five holes. The water outlet holes three, two, and one are all connected to the interior of the rinsing head, and the silicone sleeve is curved.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This solution utilizes a groove, a flushing head, and multiple water outlets (three, two, and one) inside the silicone sleeve to ensure a more even water flow. This effectively reduces local pressure on the vaginal mucosa, lowers the risk of damage, and prevents incomplete cleaning from affecting subsequent drug absorption. Consequently, it thoroughly flushes out gel aggregates and other secretions from the vagina, improving drug absorption rates and reducing the risk of embryo implantation failure and miscarriage.

[0019] This design increases the contact area and friction with the vaginal wall through the silicone sleeve, bump one, and bump two, which helps to more effectively remove gel buildup and other secretions. The grooves help to expel drug residues and keep the inside of the vagina clean, thereby ensuring comfort and safety during use and reducing irritation to the vaginal mucosa.

[0020] The irrigator's interchangeable parts—the irrigator head, connector, and reservoir—allow for quick disassembly, facilitating cleaning and disinfection. It effectively helps patients remove accumulated Crinone gel and other secretions, maintaining a clean vaginal environment, improving treatment efficacy and comfort. Furthermore, the reusable irrigator significantly reduces the cost for patients. Attached Figure Description

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides an improved vaginal irrigator for IVF-ET, including a reservoir 1 and a connection port 2. One end of the reservoir 1 is provided with the connection port 2. The outer surface of the connection port 2 is connected to the irrigating head 3 by threads. The outer surface of the irrigating head 3 is provided with a silicone sleeve 4. Multiple protrusions 5 are fixedly connected to the outer surface of the silicone sleeve 4. Three grooves 6 are opened on the outer surface of the silicone sleeve 4. Five water outlet holes 7 are evenly opened inside the three grooves 6.

[0031] Specifically, the top of the rinsing head 3 is provided with a water outlet hole 2 8, and a protrusion 2 9 is fixedly connected to the top of the rinsing head 3. The total length of the rinsing head 3 is 8.5 cm, the top length is 3 cm, the diameter of the rinsing head 3 is 1 cm, the body length is 5.5 cm, the diameter is 0.8 cm and gradually decreases evenly to 0.6 cm at the tail end. The protrusion 1 5 and protrusion 2 9 are hemispherical with a diameter of 0.2 cm. A soft pad is fitted on the outer surface of both protrusion 1 5 and protrusion 2 9. The depth of the groove 6 is 0.15 cm, and the width decreases from top to bottom, between 0.5 cm and 0.3 cm. The outer surface of the silicone sleeve 4 is provided with multiple water outlet holes 3 10, and each group of water outlet holes 3 10 has five holes. The water outlet holes 3 10, water outlet hole 2 8, and water outlet hole 1 7 are all connected to the interior of the rinsing head 3. Therefore, the silicone sleeve 4 is curved.

[0032] Next, apply a lubricant (such as a water-soluble lubricant) to the outside of the silicone sleeve 4 on the surface of the rinsing head 3, then insert the rinsing head 3 into the vagina until the tip of the rinsing head 3 is close to the cervix. Then squeeze the reservoir 1 to make the cleaning solution spray out evenly through the second water outlet 8 at the tip of the rinsing head 3 and the first water outlet 7 and the second water outlet 10 on the silicone sleeve 4, covering the entire inside of the vagina. By repeatedly squeezing the reservoir 1, ensure that the cleaning solution flows fully to help remove gel buildup and other secretions.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. One end of the liquid storage bladder 1 is provided with a connection port 2, and the outer surface of the connection port 2 is connected to a flushing head 3 by a thread.

[0035] Specifically, the reservoir 1 has a capacity of 200 ml and is made of soft plastic material, with an elastic rubber pad attached to its surface.

[0036] Furthermore, the entire irrigator is thoroughly cleaned and disinfected to ensure sterility. An appropriate amount of warm water or other doctor-recommended irrigating solution is added to the reservoir 1. Then, the irrigating head 3 is connected to the connection port 2 of the reservoir 1 via threads, ensuring a tight connection. This allows the irrigator to be reused, greatly reducing the cost for patients to purchase irrigators.

[0037] Working principle: Before use, thoroughly clean and sterilize the entire irrigator to ensure sterility. Add an appropriate amount of warm water or other doctor-recommended irrigation solution to the reservoir 1. Then, connect the irrigation head 3 to the connection port 2 of the reservoir 1 via threads, ensuring a tight connection. The patient should assume a comfortable position, usually supine with legs slightly apart. Apply lubricant (such as a water-soluble lubricant) to the outside of the silicone sleeve 4 on the surface of the irrigation head 3. Insert the irrigation head 3 into the vagina until the tip of the irrigation head 3 approaches the cervix. Then, squeeze the reservoir 1 to allow the irrigator to clean. The solution is evenly sprayed out through the water outlet 2 8 at the top of the rinsing head 3 and the water outlet 1 7 and water outlet 2 10 on the silicone sleeve 4, covering the entire vaginal cavity. By repeatedly squeezing the reservoir 1, the cleaning solution is ensured to flow fully, helping to remove gel buildup and other secretions. After rinsing, the patient can stand or squat to allow the cleaning solution to flow out naturally, thus making the rinsing device reusable. This greatly reduces the cost of purchasing a rinsing device for the patient, ensures the rinsing effect, improves drug absorption rate, and provides a guarantee for the patient's successful pregnancy. It is beneficial to the patient, reproductive center, and hospital.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
