Description

Novel three-cavity catheter

Technical Field

The utility model relates to a catheter, in particular to a novel three-cavity catheter.

Background

The bladder irrigation is a treatment mode that an irrigation solution is infused into the bladder by using a catheter, the infused irrigation solution is drained out by using a siphon principle, blood clots, foreign matters and the like in the bladder can be cleared by the bladder irrigation, the effects of stopping bleeding and preventing ureter blockage are achieved, the drainage is ensured to be smooth, secondary bleeding and bladder spasm are avoided, incision healing is promoted, pain and stimulation of a patient are relieved, infection is prevented, and the recovery of the bladder function is facilitated.

In the treatment is washed to the bladder, medical personnel generally use novel three chamber catheters to wash, and novel three chamber catheter one end is equipped with sacculus and urination mouth, and the other end is equipped with three accent, and one of them accent meets the gasbag so that the sacculus expands to fixed catheter when keeping somewhere the catheterization, wherein another accent meets the drainage bag, and the drainage urine, third accent are used for inserting the bladder flush fluid and carry out the bladder and wash. But after washing, novel three chamber catheters are inserted the mouth and do not have the plugging material of matching again, use disposable collection urine bag to connect usually, and not only operation process is loaded down with trivial details relatively, increases nurse's work load, increases patient's medical material consumption.

Therefore, a three-cavity urine pouring tube containing a stopper needs to be designed for blocking the cavity opening of the novel three-cavity catheter after bladder washing.
