Bladder irrigation catheter

Abstract

The invention discloses a bladder irrigation catheter, which comprises a catheter body. The catheter body is internally provided with a urine outlet passage and is provided with a plurality of urine holes communicated with the urine outlet passage, and a bulb is connected to the lower side wall of one end, contacting with the urethral orifice, of the catheter body. The catheter body is internallyprovided with a vent passage in communication with the bulb, a vent tube penetrating the side wall of the catheter body is connected to the other end of the vent passage, and one end, extending into the urethra, of the catheter body is provided with a cleaning hole. The catheter body is internally provided with a cleaning passage, a sleeve ring in slide connection with the catheter body sleeves the outer wall of the catheter body and is connected with a fixing piece for being fixed to the abdomen skin of a patient, and one end, extending into the urethral orifice, of the catheter body is provided with a pressure sensor for detecting internal pressure of the bladder. The outer wall of the other end of the catheter body is provided with a sound alarm and a battery. The bladder irrigation catheter has advantages that blockage of the catheter can be prevented, and timely alarming is realized even if blockage occurs.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a urinary bladder flushing catheter. Background technique [0002] In the clinical practice of urology, bladder bleeding, bladder stones and bladder spasm are important causes of urinary catheter obstruction; the existing catheter drainage hole diameter and quantity are limited, and the effective drainage channel is often vulnerable to blood clots, stones and even spasm. Blockage of the bladder mucosa, resulting in poor drainage. For patients with bladder bleeding that forms blood clots or bladder stones, if the bladder is not flushed in time or not thoroughly, it will cause blockage of the urinary catheter, which may cause life-threatening to the patient. In addition, patients who retain the catheter are prone to bladder spasm, which leads to blockage of the catheter and unsmooth drainage.

Problems solved by technology

[0002] In the clinical practice of urology, bladder bleeding, bladder stones and bladder spasm are important causes of urinary catheter obstruction; the existing catheter drainage hole diameter and quantity are limited, and the effective drainage channel is often vulnerable to blood clots, stones and even spasm. Blockage of the bladder mucosa, resulting in poor drainage

For patients with bladder bleeding that forms blood clots or bladder stones, if the bladder is not flushed in time or is not flushed thoroughly, the urinary catheter will be blocked, which may be life-threatening for the patient

In addition, patients who retain the catheter are prone to bladder spasm, which leads to blockage of the catheter and unsmooth drainage. Frequent bladder irrigation and replacement of the catheter will not only pose a safety hazard for the patient, but also increase the daily workload of medical workers

[0003] Traditional indwelling catheters are prone to urine leakage, urinary retention after extubation, urinary tract infection, urethral sphincter spasm, benign prostatic hyperplasia, etc.

Although the existing urinary catheter can flush the bladder by injecting flushing fluid, if the tube body is blocked by blood clots in the bladder, the flushing fluid cannot be injected and play a role; therefore, it is necessary to develop a catheter that can effectively prevent blood clots in the bladder , stones or bladder mucosa blocking the catheter device is very necessary and beneficial for patients
