Description

A continuous flushing device after bladder blood clot tamponade

technical field

The utility model relates to the field of medical equipment, in particular to a continuous flushing device after bladder blood clot is filled.

Background technique

Urology patients with hematuria are commonly seen in patients with upper urinary tract tumors, renal contusions, prostate and bladder perioperative surgery. These patients usually require a three-lumen urinary catheter for continuous bladder irrigation to remove blood clots, tissue blocks, and bacterial contaminants. Wait until the bladder is flushed out. When the patient has heavier bleeding or is not flushed in time, it will often lead to a larger blood clot. The traditional clinical use of the three-lumen catheter cannot achieve the expected effect in the use of bladder packing or urinary catheter blockage. At the same time, due to its latex material, suction tends to collapse the thick latex tube wall when the blood clot is blocked. In addition, due to the limitation of the tube diameter, the three-lumen catheter is partially occupied by the water inlet lumen and the balloon lumen, leaving behind The diameter of the outlet pipe is smaller, and larger blood clots cannot be drawn out. In clinical use, doctors have to replace the urinary catheter repeatedly and flush the urinary catheter repeatedly. Not only does it bring mental stress to doctors, but it also brings great pain to patients. The stimulation of the blood clot can also worsen bladder bleeding, creating a vicious cycle. If it continues to deteriorate, patients often need to enter the operating room for surgery to remove blood clots, which increases the pain and economic burden of patients. Therefore, an efficient, convenient and economical bladder blood clot packing and flushing device is urgently needed in clinical work.
