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 number are limited, and the effective drainage channel is often vulnerable to blood clots, stones and even spasm The bladder mucosa is blocked, 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

Embodiment 1

[0022] Such as Figure 1~Figure 5 As shown, the bladder flushing anti-blocking urinary catheter includes a tube body 1 and an air bag 2, and a filter screen 3 is arranged on the outside of the air bag 2;

[0023] The bladder flushing anti-clogging catheter is made into a single-lumen catheter, which is made of silica gel, which is almost non-irritating, has good biocompatibility, and the patient has no foreign body sensation, and is non-toxic and non-corrosive; The catheter intubation process has little damage to the urethral mucosa, and the incidence of hematuria is low, which further avoids the patient’s discomfort and pain during the indwelling catheter process, significantly reduces the patient’s urine leakage, urethral burning pain and anxiety, and effectively prevents hemorrhage in the bladder from forming blood clots blocks leading to obstruction of the urinary catheter;

[0024] The shape of the air bag 2 is spherical, which has a fixing effect and can prevent the uri...

Embodiment 2

[0028] Such as Figure 1~Figure 5 As shown, the present invention includes a pipe body 1 and an air bag 2, and a filter screen 3 is arranged on the outside of the air bag 2;

[0029] The bladder flushing anti-blocking catheter is actually made into a two-cavity catheter; it is made of rubber, almost non-irritating, has good biocompatibility, and the patient has no foreign body sensation, and is non-toxic and non-corrosive; The urinary catheterization process has little damage to the urethral mucosa, and the incidence of hematuria is low, which further avoids the discomfort and pain of the patient during the indwelling catheterization process, significantly reduces the patient's urine leakage, urethral burning pain and anxiety, and effectively prevents the formation of blood in the bladder.

Abstract

Disclosed is an anti-blockage urinary catheter, comprising a catheter body (1) and a balloon (2), wherein the balloon is provided on the catheter body at a site close to the tail end and the balloon is provided with a filter net (3) outside, wherein the filter net coats the tail end of the catheter body and is ovoid when in the open state. After placing the urinary catheter into the bladder, air is inflated into the balloon or water is injected into the balloon, in order to fully open the balloon and stretch the filter net to contact with the liquid in the bladder in the maximum area, thus preventing the bladder from bleeding to form blood clots, bladder stones and bladder mucosa to block the pipe orifice thus leading to overactive bladder filling.

Description

technical field [0001] The invention belongs to the field of medical surgical instruments, and relates to a urinary bladder flushing anti-clogging catheter, in particular to a filter-type anti-clogging urinary 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 number are limited, and the effective drainage channel is often vulnerable to blood clots, stones and even spasm The bladder mucosa is blocked, 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. Frequen...
