Description
Technical Field
The invention belongs to the field of medical surgical instruments, relates to a bladder irrigation anti-clogging catheter, and particularly relates to a filter screen type anti-clogging catheter.
Background
In urological clinical practice, intravesical bleeding, cystolith and cystospasm are important causes of catheter obstruction; the current catheter drainage mouth aperture and quantity are limited, and effective drainage passageway often receives the jam of clot, calculus and even spastic bladder mucosa, causes the drainage not smooth. If a patient with bladder bleeding and forming blood clots or bladder stones does not wash or wash the bladder thoroughly in time, the catheter can be blocked, and the patient is likely to be in life danger. In addition, bladder spasm easily appears in the patient who remains the catheterization, leads to the catheter to block up, and the drainage is unsmooth, and frequent bladder is washed and is changed the catheter and not only can form the potential safety hazard to the patient, has also increased medical staff's daily work load.
The traditional indwelling catheter is easy to cause urine leakage, urine retention after tube drawing, urinary tract infection, urethral sphincter spasm, prostatic hyperplasia and the like, which can cause the problems of difficult tube placement, unsmooth drainage and the like. Although the existing catheter can flush the bladder by injecting the flushing fluid, if the blood clot in the bladder blocks the catheter body, the flushing fluid cannot be injected and acts; therefore, it would be desirable and advantageous to develop a catheter device that effectively prevents blood clots, stones, or bladder mucosa from blocking the orifice in the bladder.
disclosure of Invention
The invention aims to overcome the defects or shortcomings of the prior art and provides an anti-clogging urinary catheter for bladder irrigation; the catheter is a filter screen type anti-clogging catheter, and is suitable for patients with bladder hemorrhage and blood clot formation, patients with bladder calculus, and general retention catheterization to prevent the catheter blockage caused by bladder spasm.
According to the bladder irrigation anti-clogging catheter, the head of the catheter body is provided with the filter screen structure which is smooth and has a filtering effect; the net structure is oval, when the catheter is placed into the bladder, the air bag is inflated or injected with water, the air bag is fully expanded, and the filter screen is stretched to enable the air bag to contact liquid in the bladder to the maximum area, so that blood clots formed by internal hemorrhage of the bladder, bladder stones and bladder mucosa blocking the orifice of the pipe to cause the bladder to be excessively full can be prevented, and the injected flushing liquid can flush the bladder, so that the treatment effect of the patients can be effectively improved.
specifically, the bladder irrigation anti-clogging catheter comprises a catheter body 1 and an air bag 2, and is characterized in that a filter screen 3 is arranged on the outer side of the air bag 2;
in the invention, the bladder irrigation anti-clogging catheter can be made into various specifications according to actual requirements; in the embodiment of the invention, the bladder irrigation anti-blocking catheter is respectively made into a single-cavity catheter, a two-cavity catheter, a three-cavity catheter and the like;
The bladder irrigation anti-clogging catheter is prepared from materials such as rubber, latex or silica gel; in one embodiment of the invention, the bladder irrigation anti-clogging catheter is prepared from silica gel, so that the catheter is almost free of irritation, good in biocompatibility, free of foreign body sensation for patients, non-toxic and non-corrosive; the silica gel air bag catheter has small damage to urethral mucosa in the intubation process and low hematuria incidence, further avoids uncomfortable and painful feeling generated in the catheter indwelling process of a patient, obviously relieves the patient's urine overflow, urethral burning pain and anxiety, and effectively prevents the urinary bladder from bleeding to form blood clots to block the catheter;
In the invention, the air bag 2 is spherical in shape, has a fixing effect and can prevent the catheter from falling off;
In the invention, the filter screen 3 is arranged outside the air bag 2, the surface of the filter screen is smooth and oval, the filter screen has a filtering function, and has biocompatibility, hydrophilicity, flexibility, kink resistance and good elasticity; the filter screen 3 can be fully filled in the bladder, has the filtering function on the internal hemorrhage of the bladder and the like, can effectively prevent blood clots and the like formed by the internal hemorrhage from obstructing the catheter, and simultaneously can also enable flushing fluid to smoothly enter the bladder to flush the blood clots.
When in use, the air sac 2 is placed in the bladder of a patient, the catheter is fixed, and the flushing fluid is injected into the bladder from the tube body 1 and flushes the bladder; the filter screen 3 filters and blocks the hemorrhage in the bladder to form blood clots, bladder stones and bladder mucosa so as to avoid the blood clots, the bladder stones and the bladder mucosa from blocking the pipe orifice of the catheter.
the use result shows that the bladder irrigation anti-blocking catheter can overcome the common catheter blocking phenomenon in the current urinary clinic, can ensure that the catheter can play the role of draining the bladder and simultaneously can prevent the internal hemorrhage of the bladder and the like from blocking the catheter, and greatly improves the safety and the treatment effect of the clinical operation; the pain of the patient when the catheter is kept in place can be relieved, the complications of the catheter can be reduced, the success of keeping in the urinary catheter and the smoothness of drawing the catheter can be ensured, the convenience is brought to the patient, and the health recovery is promoted.
the bladder irrigation anti-clogging catheter can effectively prevent the urinary bladder from bleeding to form blood clots, vesical calculus and bladder mucosa from being blocked, filter the blood clots, drain the bladder, inject flushing fluid, keep the drainage smooth, and improve the clinical cure rate of urology surgery and the safety of operation.
