Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a double-cavity 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 catheters mainly comprise two types of double-cavity catheters and three-cavity catheters, wherein the double-cavity catheter comprises a main pipe body, a fixed balloon water injection end and a urine discharge end which are connected with the rear end of the main pipe body, and a urine discharge hole communicated with the urine discharge end and a spherical bladder fixed balloon communicated with the water injection end of the fixed balloon are arranged on the front section pipe wall of the main pipe body; the three-cavity catheter is based on the double-cavity catheter, and the rear end of the main tube body is added with a bladder flushing end communicated with the urination hole. During clinical application, the urine bag is connected to the urination end, the main tube body is lubricated by liquid paraffin, the head end of the main tube body is inserted into the bladder through the external urethral opening, the bladder fixing balloon is filled by water injected through the water injection end of the fixing balloon, and the main tube body is pulled back to enable the bladder fixing balloon to be close to the internal urethral opening.
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, which is characterized in that a truncated cone-shaped urine leakage prevention balloon is arranged on a main pipe body close to the rear end of a bladder fixing balloon; notice No. CN 210057103U's utility model discloses a leak protection catheter sets up the elasticity valve of parcel bladder fixed sacculus on being responsible for the body, forms the toper leak protection sacculus that encircles body outer wall when full bladder fixed sacculus. 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 urethra internal orifice, throat and urethra external orifice, and the ureter is through three stenosis back, and there is the clearance between other positions of urethra and the ureter is responsible for the body, 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 ureter is responsible for between the body and the urethra gap great, and the urine of urethra internal orifice 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.
