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 and anti-blocking urinary catheter includes a tube body 1 and an airbag 2, and a filter 3 is arranged outside the airbag 2;

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

[0024] The airbag 2 has a spherical shape, has a fixing effect, and can prevent the catheter f...

Embodiment 2

[0028] Such as Figure 1~Figure 5 As shown, the present invention includes a tube body 1 and an airbag 2, and a filter 3 is provided outside the airbag 2;

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

[0030] The airbag 2 has a spherical shape, has a fixing effect, and can prevent the catheter from falling off;

[0031] The filter mesh 3 is arranged on the ...

Embodiment 3

[0034] Such as Figure 1~Figure 5 As shown, the bladder flushing and anti-blocking urinary catheter includes a tube body 1 and an airbag 2, and a filter 3 is arranged outside the airbag 2;

[0035] The bladder flushing anti-blocking urinary catheter is made into a three-lumen urinary catheter according to actual needs; it is made of latex material, which is almost non-irritating, has good biocompatibility, has no foreign body sensation in patients, and is non-toxic and non-corrosive; The balloon catheter intubation process has little damage to the urethral mucosa, low incidence of hematuria, and further avoids the discomfort and pain of the patient during the indwelling catheter process, significantly reduces the patient's urine discharge, urethral burning and anxiety, and effectively prevents the bladder Internal bleeding forms a blood clot which leads to obstruction of the catheter;

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...
