Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to a three-lumen urinary catheter plug. Background Technology

[0002] A three-lumen balloon catheter has three lumens: an inlet for inflation, an outlet for drainage, and a flushing outlet. The inlet inflates or injects liquid into the balloon near the catheter tip to secure the catheter. The outlet connects to a urine bag to collect urine, and the flushing outlet connects to flushing fluid. Three-lumen balloon catheters are commonly used for patients with bladder or prostate bleeding after urological surgery who require continuous bladder irrigation to prevent or reduce blood clot formation.

[0003] In clinical practice, after continuous bladder irrigation stops, the irrigation port needs to be sealed to maintain the sterility and airtightness of the catheter. Currently, most mainstream three-lumen catheters on the market do not have dedicated, independent sealing plugs. Some catheters, although equipped with a plug at the end, have the plug connected to the irrigation port, and during continuous bladder irrigation, this plug becomes contaminated due to prolonged exposure, compromising sterility. Furthermore, some patients with cystostomy who do not wish to wear a drainage bag long-term also require a dedicated plug to seal the catheter and create a sterile pathway. Therefore, patients who stop continuous bladder irrigation or require catheter clamping often need to use temporary alternatives for sealing, which is inconvenient. Some literature reports the use of disposable heparin caps for sealing. However, the irrigation port of the urinary catheter is relatively soft and lacks support, and the heparin cap is cylindrical, making it difficult to insert and remove. Other methods include using the cap at the end of the drainage bag for sealing, but this risks dislodgement due to size mismatch. Other methods include using large needle caps or clamps for blocking, which are not only unprofessional and aesthetically unappealing, but also prone to dislodgement, increasing the risk of urinary tract infection. In summary, currently, there is no suitable, independent, and dedicated plug for sealing the irrigation port of the three-lumen balloon catheter during the cessation of continuous bladder irrigation. Therefore, this study aims to improve upon the existing structure and address its shortcomings, providing a three-lumen catheter plug to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a three-lumen urinary catheter plug, which is achieved by the following specific technical means:

[0005] A three-lumen urinary catheter plug includes a main body and a cap. The main body has a through hole at its center, and the plug is integrally formed on the outer side of the main body. The plug has a conical structure. The plug has multiple sections, and the diameter decreases from top to bottom.

[0006] Furthermore, a connecting ring is integrally formed on the top of the main body, and the outer side of the connecting ring is threadedly connected to the inner side of the cap.

[0007] Furthermore, a connecting plug for connecting a syringe is integrally formed on the top of the main body corresponding to the through hole, and the top of the connecting plug passes through the connecting ring and is located on the top side of the connecting ring.

[0008] Furthermore, the cap is provided with a receiving hole for accommodating a connecting pipe plug.

[0009] Furthermore, the plug is made of ABS plastic.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention, through the cooperation of the connecting ring and the cap, allows for easy removal and installation of the cap from the connecting ring, and seals the flushing port on the urinary catheter, forming a closed sterile passage between the urinary catheter and the flushing port, preventing external contamination of the urinary catheter and the flushing port during prolonged use.

[0012] This invention, through the conical structure of the plug, allows the plug to be installed into flushing ports of different inner diameters, and also allows the plug to be installed on other similar drainage tubes, increasing the applicability of the product. Attached Figure Description

[0022] As attached Figure 1 To be continued Figure 4 As shown:

[0023] This utility model provides a three-lumen catheter plug, including a main body 1 and a cap 2. The main body 1 has a through hole at the center, and the plug is integrally formed on the outer side of the main body 1. The plug has a conical structure. The plug has multiple sections, and the diameter decreases from top to bottom.

[0024] The main body 1 has a connecting ring 3 integrally formed on its top end. The outer side of the connecting ring 3 is threadedly connected to the inner side of the cap 2, which can stably fix the cap 2.

[0025] The main body 1 has a connecting plug 4 integrally formed on the top of the corresponding through hole for connecting the syringe. The top of the connecting plug 4 passes through the connecting ring 3 and is located on the top side of the connecting ring 3.

[0026] The cap 2 is provided with a receiving hole 5 for accommodating the connecting pipe bolt 4, so as to prevent the connecting pipe bolt 4 from being bent and damaged when the cap 2 is screwed onto the connecting ring 3.

[0028] The working principle of this embodiment is as follows: When the main body 1 is needed, the main body 1 is first inserted into the irrigation port and fixed by the plug. Then, the connecting tube plug 4 is connected by the syringe to start the irrigation operation on the patient. After the irrigation is completed, the syringe is removed and the cap 2 is screwed onto the connecting ring 3 to close the main body 1 and form a closed sterile passage between the urinary catheter and the irrigation port, preventing the urinary catheter and the irrigation port from being contaminated by the outside world during long-term use.
