Description
Technical field
This utility model relates to a kind of catheter, especially a kind of have the drain inflammation-diminishing function, a disposable shaped grooved silicone catheter, and it mainly makes drain secretions, flushing urethra or injection anti-inflammatory analgesic for section office such as clinical urinary system Medicine and Surgery, department of obstetrics and gynecology in clinical indwelling catheter.
Background technology
Catheter commonly used is latex catheter and silicone catheter in the market, market at home, latex catheter is occupied an leading position, and in developed country markets such as America and Europes, the catheter that the urethral catheterization indwelling time surpassed two days or the child uses, its silicone catheter is occupied an leading position, and silicone catheter more is applicable to medical science than latex catheter and uses.Silicone catheter and latex catheter contrast are as follows:
1. silica gel material is that WHO assert one of four kinds of materials can forever keeping somewhere in the human body; The chemical composition of silica gel and physical arrangement have determined that it has the advantages that other same type of material is difficult to replace: stable chemical performance, Heat stability is good, absorption property be high, to organize compatible large, higher mechanical strength etc. arranged.And the latex material chemical property is unstable, poor heat resistance, compatible relatively poor to organizing, and mechanical strength is low.
2. silicone catheter has good biocompatibility, and no cytotoxicity is without sensitization and irritant reaction.And that latex catheter contains is a kind of to endoceliac cell noxious substance, and cell-cytotoxic reaction is arranged, and can cause the reactions such as urethra inflammation; Latex is large to tissue irritation, can cause allergic reaction.
3. the silicone catheter product is very soft, is transparent or semitransparent body, is convenient to the observation of urine flow, but higher about two times of the relative latex catheter of price.Two latex catheter product quality are too soft, and medical personnel operate relatively difficult, are difficult to it is inserted intravesical smoothly.
4. the silicone catheter internal diameter is broad, and more than two times, interior tract can not form knot calcium, precipitation to its drainage flow greater than latex catheter, and it is logical to cause inadequate drainage, has thoroughly solved conduit and has stopped up the problem that causes difficulty in decannulation.And the latex catheter internal diameter is narrow and the long period indwelling uses latex catheter to cause that easily involucrum forms, it is to form owing to the mineral salt in the urine is deposited on the urinary catheter, make and form knot calcium, precipitation on the interior tract, be unfavorable for drain, then again intubate can be caused, then difficulty in decannulation can be caused as the catheter obstruction occurs.
5. silicone catheter is suitable for the medium-term and long-term indwelling catheter in the human body, and the longest indwelling time is 29 days, can avoid repeatedly intubate like this, alleviates and reduce patient's misery and the generation of urinary tract cross infection; Simultaneously, through clinical confirmation, can make patient's uncomfortable degree drop to minimum with silicone catheter.Latex catheter does not then have this effect.
Existing disposable use silicone catheter generally comprise silica gel pipe shaft, sacculus claim water pocket, tip or claim head, drain cone-shaped interface, fill up cone-shaped interface, flushing cone-shaped interface and air valve.Alleged silicone catheter refers to the catheter made with silastic material, the front portion of silica gel body is provided with sacculus and tip, silica gel body between sacculus and tip has porus excretorius, body in sacculus has the sacculus hole, the rear portion of silica gel body is provided with and drains cone-shaped interface, fills up cone-shaped interface, unidirectional charge valve is housed filling up cone-shaped interface, this is a kind of two chamber silicone catheters, mainly is applicable to clinically controlled micturition; The rear portion of silica gel body is provided with and drains cone-shaped interface, fills up cone-shaped interface and flushing cone-shaped interface, and this is a kind of three chamber silicone catheters, mainly is applicable to clinically controlled micturition and washed bladder.Draining cone-shaped interface connects by tract in the drainage of silica gel body and the porus excretorius that is positioned at body sacculus front portion, be used for controlled micturition, filling up cone-shaped interface connects by the interior tract of filling up of silica gel body and sacculus hole, after sacculus gas injection or water filling, can fill up sacculus by unidirectional charge valve, be used for the fixing urinary catheter of keeping somewhere, the flushing cone-shaped interface connects by irrigation lumen road and the flushing hole on the top guide of silica gel body, and saline injection or water for injection can be used for washed bladder.Because the sacculus of existing silicone catheter sticks on the silica gel tube wall, adopt sacculus mold pressing or technique for sticking to form, section all can form convex at the body sacculus, do not become line style with body external diameter roundness, insert clinically or extract out in the urethra process, make that patient's urethra breathing sense is frequent, the pain aggravation, be not easy to urethra and insert or extract out; These exopathogenic factor three chamber silicone catheters are generally without gag, and in the indwelling catheter process, urine flows into the outflow of flushing cone-shaped interface and clinical care is made troubles from rinse mouth.
