Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a medical device and its usage for assisting in the treatment of urethral or vaginal infections. Background Technology

[0002] Urethritis or vaginitis is a common disease, mostly caused by pathogens ascending into the urethra or vagina and infecting the urethral or vaginal mucosa, leading to inflammation. It can occur in both men and women. Differentiation can be made based on medical history and bacteriological examination. Most cases are bacterial infections, such as gonococcal urethritis or vaginitis. Bacterial infections are usually treated with oral, injectable, or intravenous antibiotics. However, these methods act systemically and can potentially harm organs. Local therapies are also available, such as injecting antibiotic solutions into the urethra or vagina to enhance the efficacy of oral, injectable, or intravenous treatments. However, injected antibiotic solutions are easily expelled from the urethra or vagina, failing to effectively and persistently cover the infected area. Furthermore, the procedure is cumbersome, requiring precise control and complicating adjunctive therapy. These problems urgently need to be addressed. Summary of the Invention

[0003] The main problem solved by this invention is how to enable liquid drugs to be distributed in the urethra or vagina for a long time.

[0004] A medical device for adjuvant treatment of urethral or vaginal infections, characterized by comprising a traction head, an insertion tube, a sponge tube, and a sliding sleeve. The traction head is hemispherical. One end of the insertion tube is connected to the traction head. A series of holes are evenly distributed on the sidewall of the insertion tube. The sponge tube is a hollow cylinder and is fitted around the insertion tube. The sliding sleeve is fitted around the sponge tube. In use, the traction head can introduce the insertion tube, sponge tube, and sliding sleeve into the urethra or vagina. The sliding sleeve can act as a lubricant to prevent the sponge tube from rubbing and irritating the urethra or vagina. After insertion into the urethra or vagina, the sliding sleeve can be withdrawn. The sponge tube can fit tightly against the urethra or vagina. Liquid medication can be injected into the insertion tube. The liquid medication flows out from the holes of the insertion tube and is absorbed by the sponge tube to replenish it, allowing the sponge tube to maintain a long-term drug concentration.

[0005] The beneficial effects are that the sliding sleeve can be made of plastic film material. Since the urethra or vagina is relatively small (the size of the medical device increases accordingly when used in the vagina), the sliding sleeve can significantly reduce friction and irritation during entry. The outer surface of the sliding sleeve can also be coated with a harmless lubricant, making it easier to enter the urethra or vagina. After insertion, the sponge tube can fit tightly against the urethra or vagina, providing long-lasting and effective adjunctive treatment. Liquid medication can be replenished into the sponge tube at any time to maintain a sufficient drug concentration. Even if the medication is excessive, it can be blocked by the traction head and will not enter the deep part of the urethra or vagina, affecting health. At the same time, the traction head has an arc-shaped outer surface, making it easier to insert into the urethra or vagina and less likely to irritate the infected area. The sponge tube is hollow, which not only effectively concentrates the drug concentration on the outer tube (if the sponge tube is solid in the middle, it will absorb a large amount of drug, leading to unnecessary waste), but also evenly distributes the liquid medication absorbed from the insertion tube, making the drug more effectively cover the infected area. The medication can be an antibiotic solution, leaving no drug residue after use. At the same time, the medical device can be replaced after a period of use, making it inexpensive and easy to use. In addition, the insertion tube has a certain length, which allows for easy adjustment of the position of the sponge tube to effectively cover the infected area.

[0006] The sliding sleeve is made of plastic film with a small hole at the front end. It is fitted over the traction head. When the sliding sleeve is pulled out, the small hole is enlarged and the sleeve is pulled out along the traction head and the sponge tube. The length of the end of the sliding sleeve is greater than that of the insertion tube, so that it can be easily pulled out by pinching the end of the sliding sleeve after being inserted into the urethra or vagina.

[0007] The beneficial effects are that the plastic film has good lubrication properties, which can significantly reduce friction and irritation when it enters the urethra or vagina, and the small hole at the front end can be easily stretched when pulled out, making it easy to pull out the sliding sleeve; the length of the end of the sliding sleeve is greater than that of the insertion tube, so it is easy to pinch the end of the sliding sleeve and pull it out after it is inserted into the urethra or vagina. In the specific pulling-out operation, one hand can use a thin and long object to hold the insertion tube, and the other hand can pinch the end of the sliding sleeve and pull it out.

[0008] The end of the insertion tube is equipped with a traction rope, which can be used to pull the tube out even if it is fully inserted into the urethra or deep vagina.

[0009] The beneficial effects are, firstly, that the traction rope avoids interfering with the pulling out of the insertion sleeve, and also facilitates the correct adjustment of the insertion depth of the insertion tube at any time, preventing it from going deep into the urethra or vagina. In practical use, the traction rope can be fixed to the skin around the urethra or vagina with tape; when removing the medical device, pull it out slowly by holding the traction rope. Furthermore, appropriately changing the outer diameter of the medical device also applies to vaginal infections; simple modifications are all within the scope of this invention.

[0010] The insertion tube and sponge tube are adapted to a range of lengths to accommodate urethral or vaginal infections at different depths.

[0011] The beneficial effect is that different lengths of insertion tubes are adapted to different depths of infection, avoiding the impact of excessively long insertion tubes on daily life.

[0012] The insertion tube is a silicone tube, and the holes are distributed throughout the entire wall of the silicone tube.

[0013] The beneficial effects are that the silicone material has a certain degree of flexibility, which makes it easy to insert into the urethra or vagina, and it can also bend and deform accordingly with human movement. The holes are distributed throughout the entire wall of the silicone tube, which makes it easy for liquid drugs to be injected into the insertion tube and then evenly and fully absorbed by the sponge tube, so that the sponge tube maintains the drug concentration for a long time and ensures the auxiliary treatment effect.

[0014] The sponge tube absorbs liquid medication in advance and can be directly used as an adjunct treatment for urethral or vaginal infections after being inserted into the urethra or vagina.

[0015] The beneficial effects are that the pre-absorption of liquid medication can not only directly assist in treatment, but also make the insertion of the sponge tube into the urethra or vagina more comfortable. In addition, the liquid medication can be replenished after insertion to further enhance the therapeutic effect. The method of using the medical device is characterized by including the following steps: First, insert the traction head into the urethra or vagina, then insert the insertion tube, sponge tube, and sliding sleeve into the urethra or vagina. The sliding sleeve can reduce friction and stimulation during entry. When the sliding sleeve is pulled out, the small hole is enlarged and pulled away along the traction head and the sponge tube. Specifically, when pulling out, use a thin, long object to hold the insertion tube with one hand and pinch the end of the sliding sleeve with the other hand to pull it out. When removing the medical device, slowly pull it out of the urethra or vagina.

[0016] The beneficial effects are that the sliding sleeve can be made of plastic film material. Since the urethra or vagina is relatively small (the size of the medical device increases accordingly when used in the vagina), the sliding sleeve can significantly reduce friction and irritation during insertion. After insertion, the sponge tube can fit snugly against the urethra or vagina, providing long-lasting and effective adjunctive treatment. Liquid medication can be replenished into the sponge tube at any time to maintain a sufficient drug concentration. Even if the medication is excessive, it can be blocked by the traction head, preventing it from entering deep into the urethra or vagina and affecting health. Simultaneously, the traction head has an arc-shaped outer surface, making it easier to insert into the urethra or vagina and less likely to irritate the infected area. The sponge tube is hollow, which not only effectively concentrates the drug concentration on the outer tube (if the sponge tube were solid in the middle, it would absorb a large amount of drug, leading to unnecessary waste), but also evenly distributes the liquid medication absorbed from the insertion tube, allowing the drug to more effectively cover the infected area. The medication can be an antibiotic solution, leaving no drug residue after use. Furthermore, the medical device can be replaced after a period of use, making it inexpensive and convenient to use. In addition, the insertion tube has a certain length, allowing for easy adjustment of the sponge tube's position to effectively cover the infected area. The plastic film has good lubrication properties, which can significantly reduce friction and irritation when it enters the urethra or vagina. In addition, the small hole at the front end can be easily stretched when pulled out, making it easy to pull out the sliding sleeve.

[0017] Secure the traction rope to the skin around the urethra or vagina with tape; when removing the medical device, pull it out slowly by holding the traction rope.

[0018] The beneficial effect is that the tape and traction rope can control the insertion depth of the insertion tube, preventing it from going deep into the urethra or vagina.

[0019] Remove the medical device before each urination and reinsert it after urination, or replace it with a new medical device.

[0020] The beneficial effects are that the insertion and removal of the medical device are relatively convenient, and the operation before and after urination is also relatively simple. In addition, the traction head can also be hollow and connected to the insertion tube, so the medical device does not need to be removed during urination. Such simple changes based on the present invention are all within the protection scope of the present invention.

[0021] When removing the medical device, ensure that the sponge tube has absorbed a sufficient concentration of medication (or other lubricating liquid) to effectively prevent the sponge tube from irritating the urethra or vagina during removal.

[0022] The beneficial effect is that after the sponge absorbs a sufficient concentration of medication (or other lubricating liquid), its lubricating properties are enhanced, which can effectively prevent the sponge from irritating the urethra or vagina when it is removed. A medical device for adjuvant treatment of urethral or vaginal infections, characterized by comprising a traction head, an insertion tube, a sponge tube, and an annular barrier. The traction head is hemispherical. One end of the insertion tube is connected to the traction head. A series of holes are evenly distributed on the sidewall of the insertion tube. The end of the insertion tube has an annular barrier to prevent the insertion tube from entering the deep urethra or vagina. The sponge tube is a hollow cylinder that fits around the insertion tube. The sponge tube is filled with liquid medication. In use, the traction head can introduce the insertion tube and sponge tube into the urethra or vagina. The sponge tube can fit tightly against the urethra or vagina. After insertion, liquid medication can be injected into the insertion tube. The liquid medication flows out from the holes of the insertion tube and is absorbed by the sponge tube to replenish it, thus maintaining a long-term drug concentration in the sponge tube.

[0023] The beneficial effects are as follows: the sponge tube is fully saturated with liquid medication before insertion. Because the urethra or vagina is relatively small (the size of the medical device increases accordingly when used in the vagina), the sponge tube can fit snugly against the urethra or vagina after insertion, providing long-lasting and effective adjunctive treatment. Liquid medication can be replenished into the sponge tube at any time to maintain a sufficient drug concentration. Even if the medication is excessive, it can be blocked by the traction head, preventing it from entering the deep urethra or vagina and affecting health. Furthermore, the curved shape of the traction head makes it easier to insert into the urethra or vagina and less likely to irritate the infected area. The hollow sponge tube not only effectively concentrates the drug concentration on the outer tube (if the sponge tube were solid, it would absorb a large amount of medication, leading to unnecessary waste), but also evenly distributes the liquid medication absorbed from the insertion tube, allowing the medication to more effectively cover the infected area. The medication can be an antibiotic solution, leaving no drug residue after use. The medical device can also be replaced after a period of use, making it inexpensive and easy to use. In addition, the insertion tube has a certain length, allowing for easy adjustment of the sponge tube's position to effectively cover the infected area. The outer diameter of the annular baffle should be slightly larger than the sponge tube. This not only prevents the entire insertion tube from entering the urethra or vagina, but also facilitates accurate adjustment of the insertion depth, preventing it from slipping out of the urethra or vagina. For men, the annular baffle can be secured to the penis with tape; for women, its position can be controlled by wearing underwear to cover the annular baffle.

[0024] The insertion tube and sponge tube are adapted to a range of lengths to accommodate urethral or vaginal infections at different depths.

[0025] The beneficial effect is that different lengths of insertion tubes are adapted to different depths of infection, avoiding the impact of excessively long insertion tubes on daily life.

[0026] The insertion tube is a silicone tube, and the holes are distributed throughout the entire wall of the silicone tube.

[0027] The beneficial effects are that the silicone material has a certain degree of flexibility, which makes it easy to insert into the urethra or vagina, and it can also bend and deform accordingly with human movement. The holes are distributed throughout the entire wall of the silicone tube, which makes it easy for liquid drugs to be injected into the insertion tube and then evenly and fully absorbed by the sponge tube, so that the sponge tube maintains the drug concentration for a long time and ensures the auxiliary treatment effect.

[0028] The sponge tube absorbs liquid medication in advance and can be directly used as an adjunct treatment for urethral or vaginal infections after being inserted into the urethra or vagina.

[0029] The beneficial effects are that the pre-absorption of liquid medication can not only directly assist in treatment, but also make it easier to insert the sponge tube due to the lubrication of the liquid medication. In addition, liquid medication can be added again after insertion to further enhance the therapeutic effect. The method of using the medical device is characterized by including the following steps: First, insert the traction head into the urethra or vagina, then insert the insertion tube and sponge into the urethra or vagina. The annular barrier at the end of the insertion tube is blocked outside the urethra or vagina, which can prevent the entire insertion tube from entering the deep part of the urethra or vagina. When removing the medical device, hold the ring-shaped guard with one hand and slowly pull it out of the urethra or vagina.

[0030] The beneficial effects are as follows: the sponge tube is fully saturated with liquid medication before insertion. Because the urethra or vagina is relatively small (the size of the medical device increases accordingly when used in the vagina), the sponge tube can fit snugly against the urethra or vagina after insertion, providing long-lasting and effective adjunctive treatment. Liquid medication can be replenished into the sponge tube at any time to maintain a sufficient drug concentration. Even if the medication is excessive, it can be blocked by the traction head, preventing it from entering the deep urethra or vagina and affecting health.

This not only prevents the entire insertion tube from entering the deep urethra or vagina, but also facilitates accurate adjustment of the insertion depth at any time, preventing it from slipping out of the urethra or vagina. When removing the medical device, ensure that the sponge tube has absorbed a sufficient concentration of medication (or other lubricating liquid) to effectively prevent the sponge tube from irritating the urethra or vagina during removal.

[0031] For men, the annular guard is fixed to the penis with tape; for women, its position can be controlled by wearing underwear to cover the annular guard.

[0032] The beneficial effect is that the medical device is suitable for both men and women, and is easy to use without affecting daily activities.

[0033] Remove the medical device before each urination and reinsert it after urination, or replace it with a new medical device.

[0034] The beneficial effects are that the insertion and removal of the medical device are relatively convenient, and the operation before and after urination is also relatively simple. In addition, the traction head can also be hollow and connected to the insertion tube, so the medical device does not need to be removed during urination. Such simple changes based on the present invention are all within the protection scope of the present invention. Attached Figure Description
