Description

Suprapublic drainage urine cather}

The present invention relates to an upper pubic catheter, and more particularly, a plug and a retractable valve connected to the upper pubic catheter short in length to selectively open and close the catheter by opening and closing the valve, and to the valve, such as a urine pack. By removing the urine pack, the urinary pack can be reduced, but the urinary catheter can be closed to reduce the ascending bacterial infection, and the length of the catheter in the bladder can be shortened to minimize the probability of complications caused by bacterial infection. It relates to the upper pubic catheter that can be used safely.

Generally, suprapubic urinary catheter is used as a device for inserting urine into the bladder through the lower abdomen and discharging urine to the outside, mainly for spinal cord paralysis patients, unconscious patients, or patients with markedly weak bladder function. It is used when the bladder needs to be emptied for other special purposes.

Polyuretic urinary catheter (foley urinary catheter) that is used most of the conventional catheter used for this purpose is a urinary catheter (1) to form a urine discharge passage therein, as shown in Figure 1, the bladder ( 9) a urine suction port (2) inserted into the urinary tract and inserted into the urinary tract, and a urine outlet (3) exposed to the outside of the patient's body at the other end of the urinary catheter to discharge urine in the urinary catheter to the outside; Is installed in the urinary tract of the urine suction port (2) side and the inflated portion 4 to expand or contract so that the end of the urinary catheter does not fall out inside the bladder, and one end portion to the swelling portion 4 through the interior of the catheter A bulging part connecting pipe (5) is formed in the passage and the other end is separated from the urinary catheter (1) and bifurcated into two parts, and distilled water is supplied through the swelling connecting pipe. The inflation control valve unit 6 for controlling the expansion or contraction the swelling portion is provided to or discharged.
