Background technology
Catheter is clinical most commonly seen medicine equipment, and being inserted from urethra after human body can be by urine from bladder drainage to body
Outside；Can take out after a urine drainage, also can Preserving time be used for multiple drainage.
However, operation and indwelling that catheter is inserted can cause lower urinary tract to damage in various degree, and the damage of lower urinary tract
Wound is easier to trigger or aggravate lower urinary tract infection, even further influence lower urinary tract whole body organ function.
Female urethra is short and thick compared with male, length only 4 cms, and orificium urethrae externum surrounding structure is complicated, even if being not inserted into
Catheter is also easy to occur urinary tract infections；Existing clinical female urethral catheterization step, generally in sterilization orificium urethrae externum and perienchyma
Referring to pressing orificium urethrae externum perienchyma with the two of proficiency afterwards is relatively fixed it, struts and exposure orificium urethrae externum, and another hand is direct
Or sterilized catheter is held with tweezers, haemostatic clamp etc., blown slowly insertion from orificium urethrae externum；When needing indwelling, with i.e. by drainage urine
Bag joint insertion catheter urine outlet, as a closed system.
There is problems with the urethral catheterization of existing female patient：
1. two fingers of operator are difficult to fixed and exposure orificium urethrae externum, especially because of such as urinary tract infections, childbirth side
Orificium urethrae externum dystopy, the orificium urethrae externum atrophy of old women or even the situation for being absorbed in anterior vaginal wall caused by the scar drawing of otch
Under；Orificium urethrae externum is fixed and the bad not only reduction catheter of exposure inserts success rate and can also greatly increase the urethra damage for the process of inserting
Wound.
2. near orifice of female urethra external as the microorganism on large and small labia surface easily contacts and pollutes complications into urethra
Urethral catheterization tube outer surface, microorganism is brought into urethra and bladder；Outside such a chamber infection namely catheter lumens outside approach cause
Infection be patients with catheterization early stage urinary tract infections main cause.
3. the mode vacantly exerted a force using finger or tweezers, haemostatic clamp holding catheter is because catheter is flexibility, tortuous row
Enter, the force direction of application be difficult to it is identical with urethra center line, the direction of direct of travel and force at an angle, parallel to urethra
The active force of center line is only a component of the power applied, therefore larger power could insert catheter, thus urethral injury
It is larger.
The content of the invention
There is provided a kind of catheter suitable for women for deficiency of the invention in order to solve above-mentioned three aspect.
The object of the present invention is achieved like this：
A kind of catheter suitable for women, including the hollow master that the solid material with inner surface, outer surface is constituted
