Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a three-way urinary catheter assembly with pressure detection. Background Technique

[0002] In the medical field, especially for patients who need to stay in bed for a long time, patients in the postoperative recovery period, and some patients with specific diseases, urinary tract management is a crucial nursing task. Traditionally, urine collection and monitoring mainly rely on simple urinary catheters and urine bag systems. There are many problems in the use of this system, such as the inability to precisely control the urine discharge speed, which easily causes discomfort to patients and may even cause urinary tract infections or bladder injuries due to improper flow rate. In addition, the traditional urinary catheter system lacks an effective pressure monitoring mechanism and cannot real-time monitor the bladder pressure, which to a certain extent limits the accurate assessment of the bladder health status of medical staff and increases the risk of urinary tract complications.

[0003] Chinese Patent Publication No. CN221286601U discloses a three-way urinary catheter with pressure detection, which relates to the technical field of urinary catheters. It includes a urinary catheter body, a three-way assembly, and a pressure detection assembly. One end of the urinary catheter body is connected to a three-way assembly, and the three-way assembly includes a main pipe and a branch pipe. The upper side of the middle part of the main pipe is fixed with a branch pipe, and the main pipe and the branch pipe are in a T-shaped structure. The upper side of the branch pipe is connected to a positive pressure joint assembly, and the upper side of the positive pressure joint assembly is connected to a pressure detection assembly. In this three-way urinary catheter with pressure detection, the bottom end of the pressure measurement tube can penetrate into the inside of the joint tube, so that the assembly cover is clamped outside the joint of the joint tube, thereby realizing the assembly between the pressure detection assembly and the positive pressure joint assembly. Similarly, one end of the joint of the joint tube can also be directly connected to an infusion device for bladder irrigation or connected to a liquid extraction device to sample bladder congestion.
