Description

Catheter capable of controlling urine flow velocity

Technical Field

The utility model relates to the field of medical equipment, specifically be a can control catheter of urine velocity of flow.

Background

The urinary catheter is a common medical device which can be inserted into a bladder through a urethra to drain urine, the purpose of the urinary catheterization is to directly lead out a urine sample without pollution from the bladder, carry out bacterial culture, measure bladder capacity and pressure and check residual urine volume, identify anuresis and urine retention so as to assist diagnosis, discharge urine for patients with urine retention so as to relieve pain, before operation of organs in a pelvic cavity, conduct urine for the patients so as to empty the bladder, and avoid accidental injury in the operation, coma, urinary incontinence or injury to the pudendum, and the urinary catheter is kept so as to keep local dryness and cleanness. After some urinary system disease operations, in order to promote the recovery of bladder function and the healing of incisions, retention catheterization is often needed to rescue shock or critically ill patients, and urine volume and specific gravity are correctly recorded so as to observe kidney functions.

The catheter is of various types, and the existing catheter can be divided into the following parts according to the manufacturing materials: PVC (plastic) catheters, dry rubber (crude rubber) catheters, silicone rubber catheters and natural latex catheters. Wherein, PVC (plastic) products are hard, have large irritation, patients feel uncomfortable, have strong foreign body sensation, but have low price; the dry glue (crude glue) product is softer, has larger irritation, is uncomfortable for patients, is easy to cause irritation of urethral mucosa after long-time use, is easy to generate calcium, but has low price; the silicone rubber catheter product is softer, good in biocompatibility, free of foreign body sensation for patients, but the surface of the silicone rubber catheter product is not easy to keep smooth and clean in the molding process, high in cost, and capable of reducing friction with the urethra, enabling insertion to be more convenient and comfortable, helping to avoid damage to the urethra or bladder, and reducing risks of bacterial infection and necrosis; the natural latex product is soft, the surface silicon is easy to treat, the irritation is small, the biocompatibility is good, a patient feels comfortable, the surface smoothness is high, the price is proper, most of the natural latex products are air bag products, and the indwelling operation is convenient. However, the silicone rubber urinary catheter and the natural latex urinary catheter are soft, and the blockage phenomenon caused by the distortion of the urinary catheter often occurs, so that the expected purpose of treatment cannot be achieved, the treatment opportunity is delayed, the pain of a patient and the urinary tract infection are increased, and unnecessary workload is increased for medical staff. The prior catheter is directly connected with a patient, the fixing effect of the catheter is poor, and the condition that the catheter of the patient is abnormal due to slippage, distortion and the like of the catheter frequently occurs. When the catheter is used, the medical staff cannot grasp the scale easily during operation, so that the catheter is easy to excessively extend into the body of a patient, and pain is caused to the patient; in addition, in the process of catheterization, the flow is not well controlled, and the patient is easy to feel distending pain.
