Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary treatment instruments for gynecological diseases, and in particular to a vaginal drug delivery device. Background Art

[0002] Among gynecological diseases, vaginitis is one of the most common diseases among women. When treating vaginal diseases in women, it is necessary to administer drugs deep into the vagina. Vaginal drug delivery devices can deliver antibacterial drugs directly to the lesion site, achieving local treatment and improving the treatment effect.

[0003] Traditional drug delivery devices have difficulties in controlling drug dosage. For example, when a drug solution needs to be injected into a patient's private parts multiple times at different time periods, it is difficult to precisely control the pushing force. This makes it difficult for patients to accurately control the dosage during use. This may lead to overdose or underdose of the drug, thus affecting the treatment effect and being unfavorable for patients to use it on their own.

[0004] Secondly, when traditional vaginal drug delivery devices are inserted into the patient's private parts, the friction between the device and the vaginal wall often causes discomfort or even pain to the patient. This discomfort not only increases the patient's psychological burden, but may also affect the patient's acceptance and compliance with treatment.

[0005] Therefore, it is necessary to provide a new vaginal drug delivery device to solve the above technical problems. Summary of the Invention

[0037] It should be noted that the injection tube 6 is for single use. In order to avoid bacterial infection, the patient needs to install the newly unsealed injection tube 6 on the medicine storage bag 3 before each injection.

[0038] See also Figure 3 and Figure 4 The rotating assembly includes: a first threaded sleeve 10, a cylinder 11, a ratchet 12, a ratchet 2 13 and a spring 14. The end of the tube body 1 away from the fixing ring 2 is internally threadedly connected to the first threaded sleeve 10, the inner wall of the first threaded sleeve 10 is fixedly connected to the ratchet 12, the first threaded sleeve 10 is internally slidably connected to the cylinder 11, the inner wall of the cylinder 11 is fixedly connected to the spring 14, one end of the spring 14 is fixedly connected to the connecting rod 15, the end of the connecting rod 15 away from the spring 14 is fixedly connected to the ratchet 2 13, the ratchet 2 13 is meshed with the ratchet 12, the outer wall of the first threaded sleeve 10 is provided with a scale bar, the end of the first threaded sleeve 10 close to the ratchet 12 is fixedly connected to the rotating cylinder 16, the end of the cylinder 11 away from the first threaded sleeve 10 is fixedly connected to the second threaded sleeve 17, and the inner wall of the second threaded sleeve 17 is threadedly connected to the threaded push rod 4;

[0039] It should be noted that the end of the tube body 1 close to the first threaded sleeve 10 is made of transparent material and has a scale pointer installed inside, so that the patient can clearly see the injected dose when taking the medicine. The design of the rotating drum 16 allows the patient to accurately control the dosage when injecting the medicine.

[0040] The spring 14 is initially compressed, and the middle cross-section of the connecting rod 15 is cross-shaped. A groove matching the connecting rod 15 is provided at the end of the cylinder 11 away from the spring 14. When the rotating cylinder 16 rotates counterclockwise, the connecting rod 15 can slide on the inner wall of the groove due to the elastic force of the spring 14. When the rotating cylinder 16 rotates clockwise, the connecting rod 15 can drive the rotating cylinder 16 to rotate due to the meshing action of the ratchet.

[0041] See also Figure 3 、 Figure 4 and Figure 5 , the inner wall of the medicine storage bag 3 is symmetrically fixedly connected to the limiting slide rail 18, and both sides of the rubber stopper 5 are provided with limiting grooves 19 that match the corresponding limiting slide rails 18. The limiting slide rails 18 are slidably connected to the inner walls of the corresponding limiting grooves 19. The interior of the liquid storage bag 8 is filled with medical lubricant, and a sponge ring 9 is installed at one end of the liquid storage bag 8 close to the medicine storage bag 3. The middle cross-section of the connecting rod 15 is cross-shaped, and a groove that matches the cross-section of the connecting rod 15 is provided at the end of the cylinder 11 away from the spring 14.

The injection tube 6 is made of silicone, the outer wall of the rotating cylinder 16 is provided with anti-slip grooves, and the outer wall of the tube body 1 is provided with a silicone pad;

[0042] It should be noted that a circular hole is opened at one end of the liquid reservoir 8 close to the sponge ring 9, so that the sponge can absorb the medical lubricant inside the liquid reservoir 8. When the injection tube 6 is inserted into the protective cap 7, the sponge ring 9 contacts the injection tube 6 and evenly adheres the absorbed medical lubricant to the outer wall of the injection tube 6.

[0043] The working principle of the vaginal drug delivery device provided by the present invention is as follows:

[0044] Preparation stage

[0045] Cleaning and Assembly:

[0046] Before starting to use, the patient should first clean his hands to ensure hygiene, rotate the fixing ring 2 to disengage it from the threaded connection with the medicine storage bag 3, exposing the external thread of the medicine storage bag 3, and then rotate the medicine storage bag 3. The limiting slide rails 18 on the inner wall of the medicine storage bag and the limiting grooves 19 on both sides of the rubber stopper 5 make the rubber stopper 5 rotate along with the medicine storage bag 3. The threaded push rod 4 fixedly connected to one end of the rubber stopper 5 will also rotate accordingly and disengage the threaded connection with the second threaded sleeve 17. Then, remove the protective cap 7 and prepare to insert the medicine storage bag 3 into the medicine liquid for filling;

[0047] Liquid filling:

[0048] Immerse the open end of the medicine storage bag 3 in the medicine liquid, then pull the threaded push rod 4. The movement of the threaded push rod 4 will drive the rubber stopper 5 to move and extract the medicine liquid into the medicine storage bag 3. After the extraction is completed, align the threaded push rod 4 with the second threaded sleeve 17 and rotate the medicine storage bag 3 until the two are tightly connected;

[0049] Device assembly and dose setting:

[0050] Rotate the fixing ring 2 so that its internal thread fits tightly with the external thread of the medicine storage bag 3, fix the medicine storage bag 3 on the tube body 1, install the injection tube 6 on the end of the medicine storage bag 3 away from the fixing ring 2, and re-cover the protective cap 7 to protect the injection tube 6;

[0051] Hold the tube body 1 and rotate the drum 16 counterclockwise. The rotation of the drum 16 drives the first threaded sleeve 10 fixed to it to rotate and extend out of the tube body 1. During this process, the ratchet wheel 12 continuously squeezes the ratchet wheel 2 13. At the same time, the spring 14 in the compressed state releases its elastic force to push the ratchet wheel 2 13 to move with the first threaded sleeve 10, so that the ratchet wheel 2 13 and the ratchet wheel 1 12 are always in meshing state.

[0052] At the same time, observe the scale bar on the outer wall of the first threaded sleeve 10 and adjust it to the predetermined dosage scale position as needed;

[0053] Injection stage

[0054] Lubrication preparation:

[0055] Remove the protective cap 7 and move the syringe 6 back and forth inside the protective cap 7 several times so that the medical lubricant in the liquid reservoir 8 inside the protective cap 7 adheres to the outer wall of the syringe 6 through the sponge ring 9 to reduce friction and discomfort during insertion;

[0056] Insertion and injection:

[0057] The patient is in an upright sitting position with his legs bent and knees spread apart so that the syringe can easily enter the patient's affected area. The syringe 6 coated with medical lubricant is slowly inserted into the patient's affected area. The patient holds the tube body 1 with one hand to keep it stable and rotates the rotating drum 16 clockwise with the other hand. The rotation of the rotating drum 16 drives the first threaded sleeve 10 to rotate along the thread direction of the inner wall of the tube body 1. At the same time, the ratchet 12 rotates and drives the meshed ratchet 2 13 to rotate together. The ratchet 2 13 drives the cylinder 11 to rotate through the connecting rod 15 (the middle cross-section of the connecting rod 15 is cross-shaped and cooperates with the groove opened at one end of the cylinder 11). The second threaded sleeve 17 fixedly connected to one end of the cylinder 11 also rotates accordingly, thereby causing the threaded push rod 4 to move forward in the tube body 1.

[0058] The movement of the threaded push rod 4 pushes the rubber stopper 5 to move forward in the medicine storage bag 3. The limiting grooves 19 on both sides of the rubber stopper 5 cooperate with the limiting slide rails 18 on the inner wall of the medicine storage bag 3 to ensure the smooth movement of the threaded push rod 4 and the uniform pushing of the liquid medicine, thereby delivering the liquid medicine to the patient's affected area through the injection tube 6;

[0059] Ending stage

[0060] Dosage control and extraction:

[0061] Continue to rotate the drum 16 until the scale value on the outer wall of the first threaded sleeve 10 is turned to the initial 0 scale. At this time, the liquid medicine in the drug storage bag 3 has been completely pushed into the affected area according to the set dose. Wait for a few seconds to ensure that the liquid medicine is fully effective, and then slowly pull out the injection tube 6;

[0062] Subsequent processing:

[0063] Remove the used syringe 6 and dispose of it properly (such as putting it in a trash can), and replace the protective cap 77 on one end of the medicine storage bag 3 to keep it sealed for use in the next time period;

[0064] The next time the medicine is used, it is only necessary to install the newly opened injection tube 6 at one end of the medicine storage bag 3, adjust the scale value of the required injection dose, and repeat the above operation to complete the medication operation on the affected area.

[0065] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
