The specific embodiment
As can be seen from Figure 1, a kind of disposable self-locking tube-placing device safe in utilization, its by last card body 1, block body 2, rubber inner core 4, master jaw 3 down and form.
The said card body 1 of going up is provided with hollow via-hole, on block body 1 top and be provided with ellipse platform 13, be convenient to dominated by hand when manipulating.Last card body 1 bottom is provided with the elastic hollow claw 12 with its integrative-structure, as Fig. 1, Fig. 2, shown in Figure 3.Rubber inner core 4 of the present invention is arranged in the hollow of hollow claw 12, and it can contraction clip fastens the drain flexible pipe that is inserted in its inner chamber with the contraction extruding of hollow claw 12.Hollow claw 12 lower ends are fixed in the draw-in groove 32 that master jaw 3 is provided with.
As can be seen, the described body 2 of card down is provided with hollow via-hole 21 from Fig. 1, Fig. 4, and following card body 2 is set in hollow claw 12 and master jaw 3 outsides, and can go up card body 1 grade relatively and move up and down, and spacing by master jaw 3.Promote downwards to go up card body 1, the hollow claw 12 that has tapering is subjected to down 2 compressings of card body, shrinks extruding rubber inner core 4 wherein, and then is fixed the drain flexible pipe in the rubber inner core 4.
As can be seen from Figure 5, described master jaw 3 centers are provided with drain flexible pipe through hole 31, and the drain flexible pipe is by last card body 1, block body 2 down, insert also by the inner chamber of rubber inner core 4 and the drain flexible pipe through hole of master jaw 3, and being presented to needs the drain position.Master jaw 3 sidewalls are axially arranged with the draw-in groove 32 that connects the hollow claw.Hollow claw 12 lower ends are fixed in the draw-in groove 32 of master jaw.
Down card body of the present invention 2 upper ends also are provided with ellipse platform 24, and are corresponding with ellipse boss 13 on the last card body 1, control use when being convenient to operate.
The present invention's card body 2 down is enclosed within hollow claw 12 outsides, is stuck between card body 1 and the master jaw 3.The insertion of drain flexible pipe is also passed through rubber inner core 4 and drain flexible pipe through hole 31.When last card body 1, when blocking body 2 spacings maximum down, following card body 2 misaligns empty calorie pawl 12 and produces the clamping compressing, and the rubber inner core 4 and the drain flexible pipe that misalign in the empty calorie pawl 12 produce pressure.Card body 1 in downward promotion, utilize the inclined-plane 14 of hollow claw 12 middle part band taperings and the elasticity that itself has, under block body 2 tight fits and clamp hollow claw 12, and then rubber inner core 4 in the centering empty calorie pawl 12 and drain flexible pipe generation pressure, shrink extruding rubber inner core wherein, and then be fixed drain flexible pipe in the rubber inner core, the drain flexible pipe is fixed.
During use, on block body 1, block body 2 down and be in separated position, the drain flexible pipe that intracranial boring back is inserted drain to needs passes from this tube-placing device, the drain flexible pipe is inserted needs the drain position, regulates down that card body 2 makes it be adjacent to skull, can adjust and put the pipe degree of depth this moment.Need be to the drain flexible pipe fixedly the time, keep that the card body is motionless down, down promote to go up the card body and get final product.As shown in Figure 6.Operation finishes the back and takes out this tube-placing device, will go up card bulk phase under block body and turn clockwise, hear " " sound, on block body boss snap into down and block in the body draw-in groove, finish the card body, block the self-locking of body down, can reach the self-destruction purpose, product can't reuse.
Simple structure of the present invention, it is easy to operate to put pipe, and can adjust and put length of tube, meet clinical needs, can effectively avoid the drain flexible pipe to deviate from and block, but self-destruction after the disposable use, product can't reuse, and realizes real disposable use, the infection risk of avoiding product to reuse causing.
