The air bag catheter comprises an air bag, a catheter body, a catheterization hole, a charging valve, an external drainage connector and an external sleeve, wherein the catheter body is sheathed in the external sleeve, a urine stopping locating groove and a catheterization locating groove are arranged at the tail end of the urethral catheter body, wherein the height position of the urine stopping locating groove and the catheterization locating groove are reduced sequentially, and a corresponding locating card is additionally arranged at the position of the tail end of the external sleeve. In the air bag catheter, the technical disadvantages that the air bag pressure point of the existing air bag urethral catheter cannot be changed, so that the sustaining harm is caused to the bladder are overcome, and the air bag urethral catheter capable of changing the bladder pressure point can be easily realized, the discomfort caused by rotation or lifting of the urethral catheter body and resistance of human tissues to the urethral catheter body are avoided, and the operation is smooth.
Description
Technical field
This utility model belongs to medical supplies, is a kind of utensil that is applicable to patient's urethral catheterization that dysuria patient, urinary tract infection are arranged.
Background technology
At present, the patient of treatment urinary hesitancy, dysuria excretes urine with catheter usually.The catheter basic composition is: be made up of air bag, urethral catheterization hole, urethral catheterization body, charging valve, external drainage interface, thin chamber and urethral catheterization lumen do not communicate in the urethral catheterization body, air bag communicates with charging valve by thin chamber, the urethral catheterization hole communicates with the external drainage interface by urethral catheterization lumen, air bag, urethral catheterization hole are positioned at the head end of catheter, wherein air bag is positioned at the side of catheter, and the urethral catheterization hole is positioned at a side relative with air bag.
The urethral catheterization body by air bag directly card be pressed in opening of bladder, secular indwelling and can't change the compressing position injures the opening of bladder of compressing place easily.If change the compressing position by the urethral catheterization body that directly moves with tissue closely contacts, the frictional resistance from tissue suffered in this process is bigger, implements quite difficulty.
The utility model content
The technical problems to be solved in the utility model provide a kind of can be simple and easy realization change the Foley catheter of balloon tamponade position.
In order to solve the problems of the technologies described above, this utility model provides following technical scheme: the Foley catheter that changes the bladder pressure point, comprise air bag, urethral catheterization body, urethral catheterization hole, charging valve, external drainage interface, be provided with not connected thin chamber and urethral catheterization lumen in the urethral catheterization body, air bag communicates with charging valve by thin chamber, the urethral catheterization hole communicates with the external drainage interface by urethral catheterization lumen, and air bag, urethral catheterization hole are positioned at the head end of urethral catheterization body, and wherein air bag is positioned at the side of urethral catheterization body; The Foley catheter of described change bladder pressure point also comprises trocar sheath, and described urethral catheterization body is socketed in the trocar sheath; Described urethral catheterization body tail end is provided with that height and position reduces successively only urinates locating slot and urethral catheterization locating slot, and trocar sheath tail end place also has additional a corresponding locator card.
Further, described urethral catheterization hole is positioned at a side relative with air bag, and its height and position of urethral catheterization hole is lower than described air bag.
Further, described trocar sheath is the hard coat pipe, and described locating slot is an annular, and its tail end of described trocar sheath is socketed in the locator card, and described locator card is the elastic ring locator card.
Adopt the technical solution of the utility model, following technique effect arranged:
1, the setting of urethral catheterization body head end can charge and discharge the air bag of gas, and be in side (the eccentric setting), urethral catheterization body and air bag be rotatable or lifting in the relatively-stationary trocar sheath in position, can change the relative position of air bag and bladder according to circumstances, change the pressure point of catheter, be difficult for producing lasting injury bladder to bladder.Between urethral catheterization body and tissue, set up trocar sheath, avoid both direct contacts, thereby avoid rotating or resistance that discomfort that lifting urethral catheterization body process urethral catheterization body brings to human body and tissue bring for the urethral catheterization body, operate also therefore smooth.
2, described urethral catheterization body tail end is provided with that height and position reduces successively only urinates locating slot and urethral catheterization locating slot, and trocar sheath tail end place also has additional a corresponding locator card.Can adjust the urethral catheterization body interior relative altitude position of sleeve pipe outside like this, finish urethral catheterization and only urinate two kinds of operations.By the size setting, urethral catheterization hole on the urethral catheterization body and two locating slots are set as corresponding size positions relation, when locator card and height and position higher only urinate locating slot and engage the time, the urethral catheterization hole is blocked by trocar sheath, urine can't be walked by drain, forms " ending urine " structure; When the lower urethral catheterization locating slot of locator card and height and position engaged, its position, urethral catheterization hole was higher than the trocar sheath upper edge, and expose in the urethral catheterization hole, and urine is walked by drain, formed " urethral catheterization " structure.
3, the urethral catheterization hole is positioned at a side relative with air bag, and its height and position of urethral catheterization hole is lower than described air bag.The position of urethral catheterization hole in the wing moon bright is lower than air bag like this, is difficult for being blocked and the thoroughly no residual urine formation of drain by air bag.
4, described trocar sheath is the hard coat pipe, and then trocar sheath can keep form (deformation does not take place) when getting involved, and the friction between trocar sheath and the urethral catheterization body does not increase (less substantially), does not influence the rotation or the lifting operation of urethral catheterization body; Its tail end of trocar sheath is socketed in the elastic ring locator card, on the one hand, can there be the free gap unavoidably between trocar sheath and the urethral catheterization body, rubber-like circular orientation card can fit tightly the trocar sheath tail end, and ending on locator card and the urethral catheterization body urinated, urethral catheterization locating slot card is loop configuration, engages with each other, and sealing fully, locator card has just sealed free gap between this place's trocar sheath and the urethral catheterization body like this, prevents that urine from outflowing from the free gap; On the other hand, locator card is an elastic construction, can make the urethral catheterization body by the formed annular space of locator card in certain elastically-deformable mode, makes the urethral catheterization body interior upper and lower mobile possibility that becomes of sleeve pipe outside.
