Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a urethral delivery device. Background Technology

[0002] Urethral drug delivery is a method of injecting therapeutic drugs into the urethra through a special instrument to achieve a therapeutic effect. Urethral drug delivery is mainly used to treat urethritis, cystitis, and other urethral and bladder-related diseases, as well as as an adjunct treatment for certain specific diseases. By delivering the drug directly to the affected area, the therapeutic effect can be improved and the side effects of systemic medication can be reduced.

[0003] Existing urethral medication administration devices typically consist of a syringe and a tubing. During use, the tip of the tubing is inserted into the patient's urethra, and the medication is injected through the tubing using the syringe. The medication tends to leak out through the gap between the urethra and the tubing. After administration, the tubing is removed, causing leakage and hindering the medication from reaching deeper into the urethra, thus reducing its effectiveness. Furthermore, for ease of insertion, the tip of existing urethral medication administration devices is often designed to be sharp, and the material is mostly hard plastic, which can easily produce sharp spikes that can scratch the urethral mucosa. Because they cannot block the external urethral opening, deep insertion is often required to reach the deeper parts of the urethra, causing patient discomfort. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a urethral drug delivery device. The syringe contains the drug solution, and the drug delivery tube and silicone drug delivery head reduce the irritation to the urethra during drug administration. The front balloon works in conjunction with the navicular fossa to block the navicular fossa and prevent the drug solution from being drawn back. At the same time, the buckle can be released after the drug has taken effect to aspirate the excess drug solution. The drug solution can reach the deep part of the urethra, thereby improving the drug's efficacy.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 A urethral medication administration device includes: a syringe 1, a support ring 2 extending from one side of the syringe 1, a medication tube 3 fixedly connected to the top surface of the support ring 2, and a recessed groove formed on the outer wall of the medication tube 3; and a fixing assembly, the fixing assembly including: a front airbag 4, a connecting air tube 7, a silicone airbag 8, and a secondary buckle 9, the front airbag 4 being sleeved in the recessed groove, the connecting air tube 7 being disposed inside the medication tube 3, and one end of the connecting air tube 7 extending to the outside of the medication tube 3, the connecting air tube 7 and the front airbag 4 being connected, the silicone airbag 8 being installed at one end of the connecting air tube 7, and the secondary buckle 9 being sleeved on the outer wall of the connecting air tube 7.

[0025] In a specific embodiment of this utility model, the syringe 1 contains the liquid medicine. The syringe 1 is a vertically arranged flexible corrugated tube with the bottom of a bottle. The administration tube 3 is made of silicone with a smooth and rounded surface. When injecting the medicine, it can minimize the irritation to the urethra. In use, first inject a small amount of liquid medicine into the urethral opening and the navicular fossa through the syringe 1 for lubrication. Then insert the administration tube 3 so that the front balloon 4 is in the navicular fossa. Open the main buckle 10 and manually squeeze the silicone balloon 8. The front balloon 4 of the urethra inflates and blocks the navicular fossa, and the liquid medicine is injected. Then close the secondary buckle 9 and the main buckle 10 to prevent the liquid medicine from being drawn back. When it needs to be removed, the secondary buckle 9 must be opened first to deflate the front balloon 4. At the same time, the buckle can be released after the medicine has taken effect to aspirate the excess liquid medicine.

[0026] Specifically, the inner wall of the administration tube 3 is provided with two retaining rings 6, both of which cooperate with the connecting air tube 7.

[0027] In this embodiment, the connecting air tube 7 is fixed by the fixing ring 6 to prevent it from moving around inside the administration tube 3, and at the same time to ensure that it does not affect the sealing effect of the administration tube 3.

[0028] Specifically, the outer wall of the administration tube 3 is provided with a main buckle 10.

[0029] In this embodiment, the connection status of the drug delivery tube 3 is controlled by the main latch 10, thereby preventing the backflow of the drug solution.

[0030] Specifically, a silicone delivery head 5 is fixedly connected to one end of the delivery tube 3.

[0031] In this embodiment, the silicone drug delivery head 5 reduces irritation to the urethra during insertion and drug administration.

[0032] Specifically, the outer wall of the silicone drug delivery head 5 has multiple liquid outlet holes.

[0033] In this embodiment, the liquid medicine is discharged through the liquid outlet.

[0034] Specifically, the administration tube 3 and the syringe 1 are connected.

[0035] In this embodiment, the drug administration operation is achieved by connecting the syringe 1 and the drug administration tube 3.

[0036] Working principle: The syringe 1 contains the medication. The syringe 1 is a vertically arranged flexible corrugated tube with the bottom of the bottle. The administration tube 3 is made of silicone with a smooth and rounded surface. When injecting the medication, it can minimize the irritation to the urethra. In use, first inject a small amount of medication into the urethral opening and fossa navicularis through the syringe 1 for lubrication. Then insert the administration tube 3 so that the front balloon 4 is in the fossa navicularis. Open the main buckle 10 and manually squeeze the silicone balloon 8. The front balloon 4 of the urethra inflates and blocks the fossa navicularis, and the medication begins to be injected. After that, close the secondary buckle 9 and the main buckle 10 to prevent the medication from being drawn back. When it needs to be removed, first open the secondary buckle 9 to deflate the front balloon 4. At the same time, the buckle can be released after the medication has taken effect to aspirate the excess medication.
