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 for the treatment of urinary hesitancy, dysuria excretes urine with catheter usually.The catheter basic composition is: be comprised 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, long-term indwelling and can't change the compressing position injures the opening of bladder of compressing place easily.If the urethral catheterization body by direct movement and tissue close contact changes the compressing position, the frictional resistance from tissue suffered in this process is larger, implements difficult.
The utility model content
The technical problems to be solved in the utility model provides a kind of Foley catheter that can simple realization changes the 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; Described trocar sheath is provided with the deep calibration line; 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 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:
But 1, the air bag of urethral catheterization body head end setting inflation/deflation, and be in side (eccentric setting), urethral catheterization body and air bag be rotatable or lifting in the relatively-stationary trocar sheath in position, can change according to circumstances the relative position of air bag and bladder, change catheter to the pressure point of bladder, be difficult for producing the lasting injury 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 are brought to 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 so the outside interior relative altitude position of sleeve pipe of urethral catheterization body, 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 edge on the trocar sheath, 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, be difficult for being blocked by air bag and drain thoroughly without residual urine formation.
4, described trocar sheath is the hard coat pipe, and then trocar sheath can keep form (deformation does not occur) when getting involved, and the friction between trocar sheath and the urethral catheterization body does not increase (substantially less), does not affect 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, have elastic circular orientation card and 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 elastic construction, can make the urethral catheterization body by the formed annular space of locator card in certain elastically-deformable mode, makes outside interior the moving up and down of sleeve pipe of urethral catheterization body become possibility.
5, because patient's physical condition is different, in order to determine the required deep distance of Foley catheter, avoid relying on fully the maloperation (stretching into long or too short) that subjective judgment causes, be provided with the deep calibration line at described trocar sheath, even if change the intervention degree of depth that Foley catheter also can decide according to the deep calibration value that Foley catheter is before determined new Foley catheter.
