Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a novel urine leakage prevention irrigation catheter.
Background
Catheterization is a conventional operation technique which must be mastered by medical staff, and refers to a process of inserting a catheter into a bladder through an external orifice of a urethra to play a role in draining urine. The common clinical catheter mainly comprises a double-cavity catheter and a three-cavity catheter, wherein the double-cavity catheter comprises a main catheter body, a fixed balloon water injection end and a urination end which are connected to the rear end of the main catheter body, and a urination hole communicated with the urination end and a spherical bladder fixed balloon communicated with the water injection end of the fixed balloon are arranged on the front section of the main catheter body; the three-cavity catheter is based on the double-cavity catheter, and the rear end of the main catheter body is additionally provided with a bladder flushing end communicated with the urination hole. During clinical application, earlier be connected to the urination end with the urine bag, use liquid paraffin lubricated main catheter body, insert main catheter body head end in the bladder through the urethra outer mouthful, again through the fixed sacculus water injection end water injection full fixed sacculus of bladder, pull back main catheter body makes the fixed sacculus of bladder press close to the urethra inner mouth.
When the urinary catheter is in actual use, the urine leakage phenomenon of men often occurs, the record of urine volume is influenced, the workload of medical staff is increased, and the embarrassing psychology of patients is easily caused by urine polluting bed sheets and trousers. Aiming at the problem of urine leakage, the utility model with the publication number of CN 209033489U discloses a convenient-to-wash urine leakage prevention catheter, wherein a truncated cone-shaped urine leakage prevention balloon is arranged on a main catheter body and close to the rear end of a bladder fixing balloon; the utility model with the publication number of CN 210057103U discloses a leakage-proof catheter, which is characterized in that an elastic valve wrapping a bladder fixing saccule is arranged on a main catheter body, and a conical leakage-proof saccule surrounding the outer wall of the catheter body is formed when the bladder fixing saccule is filled. The patent mainly adds the leak-proof sacculus, and conical leak-proof sacculus more agrees with the bladder wall around the internal orifice of urethra, and conical sacculus and bladder mucous membrane contact surface are bigger, have certain leak-proof function of urine. However, due to the lack of direct force at the interface, the pressure of the balloon against the bladder is low, and when the leak-proof balloon is activated, urine can still flow to the internal urethral opening through the gap between the balloon and the bladder folds, resulting in urine leakage. In addition, when the bladder fixing balloon is excessively inflated, the head-end ureter can greatly stimulate the bladder wall, and pain of a patient can be easily caused.
The anatomical structures of the male bladder and the urethra are analyzed to cause the phenomenon of urine leakage during the retention of the urinary catheter, and the following points are mainly considered: 1. when the bladder is empty, the volume of the bladder is reduced, the bladder inner wall generates radial bladder folds taking the urethra orifice as the center, at the moment, the bladder fixing saccule is far away from the urethra orifice, and a gap exists between the bladder fixing saccule and the bladder wall, so that urine flows into the urethra orifice through the folds; 2. the bladder fixing balloon is spherical, the bladder wall close to the inner opening of the urethra is funnel-shaped in a hollow state, the contact area between the bladder fixing balloon and the funnel-shaped bladder wall is small, and urine can easily flow into the inner opening of the urethra through a gap between the bladder fixing balloon and the funnel-shaped bladder wall; 3. when the bladder is fixed and the funnel-shaped bladder wall outer opening is close to each other, a larger space is formed between the bladder fixing saccule and the urethra inner opening, and urine in the secondary space can be extruded into the urethra through the urethra inner opening under the compression of the bladder and the bladder fixing saccule; 4. the urethra has three physiological stenosis in mouth in the urethra, throat and the external orifice of urethra, and the ureter passes through three stenosis back, has the clearance between other positions of urethra and the main catheter body of urethra, and under the effect of urethra smooth muscle, this gap is less, but old, stupor, paraplegia, patient such as diabetes, urethra smooth muscle is more lax, and the gap is great between main catheter body of urethra and the urethra, and the urine of the internal orifice of urethra department can flow through this clearance. From the analysis of the cause of urine leakage, the phenomenon of urine leakage can be prevented from the following aspects: 1. increasing the pressure of the balloon on the bladder mucosa at the urethral orifice; 2. increasing the contact area of the near-urethra internal orifice balloon and the bladder wall; 3. reducing detail between the balloon and the intraurethral space; 4. reducing the gap between the catheter and the urethral mucosa.
