Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

Drainage catheter as shown in Figure 1, including the flexible guide wire 1 of internal cavities and front end, 1 liang of the guide wire End is equipped with the opening penetrated through with internal cavities, and freely slidable puncture needle 2 is arranged in the guide wire 1 and is led through described The opening at 1 both ends of skirt, 1 front end of guide wire are equipped with multiple perforation 6 with 1 connects with the internal cavities of guide wire, The side wall of the guide wire 1 is equipped with duct 3, and the duct 3 extends along the 1 axis direction both ends of guide wire and leads with described 1 axis of skirt is parallel, and the perforation 6 is not connected to the duct 3, is equipped with guide wire 4 in the duct 3, before the duct 3 It is threaded with nut cap 5 on the inner wall of end, described 4 one end of guide wire is fixedly connected in the nut cap 5, and the other end is behind duct 3 End extends to outside the duct 3；

The cylinder 7 of upper and lower side perforation is vertically fixedly connected on 1 rear end of guide wire, the guide wire 1 is equipped with Through-hole 8 makes to be connected in its described 1 internal cavities of guide wire and the cylinder 7, is equipped in the cylinder 7 horizontally disposed and along institute The mobile piston 9 of 7 central axial direction of cylinder is stated, is vertically fixedly connected on push rod 10 at the 9 upper surface center of piston, it is described 10 other end of push rod is upwardly extended along 7 central axis of cylinder, and 9 side of piston is adapted with 7 inner wall of cylinder, is leaned on The cylinder 7 of the nearly guide wire 1 is equipped with guide hole 11, and being equipped in the through-hole 8 flows into the liquid in the guide wire 1 unidirectionally Check valve in the cylinder 7, it is described equipped with the check valve outside the unidirectional outflow tube 7 of liquid in cylinder 7 in the guide hole 11 Perforation 6 is circular hole, and internal diameter 3-5mm is fixedly connected on the hook 13 that can bundle the guide wire 4, institute on the guide wire 1 It states through-hole 8 and the 1 internal cavities joint of guide wire is equipped with filter screen, the through-hole 8 is circular hole, and internal diameter is less than the cylinder The internal diameter of body 7,1 rear end of guide wire are equipped with the valve 12 that can control 1 open rearward end of guide wire to open or close.

The front end of its guide wire of the utility model product and the equal length of rear end, the front end and rear end of guide wire Its guiding pipe outside diameter of portion joint to front end is gradually reduced, and in use, passes through the effect guide wire of puncture needle It is inserted into human body, then extracts puncture needle, close valve, by the effect of push rod and piston constantly by the hydrops in insertion site Or in pneumatosis sucking guiding tube cavity, entering in cylinder, since through hole is provided that check valve, then pressure-ram hydrops or Hydrops or pneumatosis in human body is discharged by achieving the purpose that outside guide hole outflow tube in pneumatosis, is also provided with pipeline at guide hole, together When to skid off human body outer and conducive to the more hydrops of extraction or pneumatosis is facilitated for guide wire in order to prevent, pass through control guide wire Length makes the front end of guide wire bend, and guide wire one end is bundled in hook above again, easy for operation, simultaneously After hydrops extraction is finished, piston is pushed into the bottom of cylinder, opens valve, the opening connection in guide wire rear end is led Pipe circulates in conduit for rinsing the intracorporal cleaning solution of people (physiological saline or other flushing liquors), be then shut off valve again into Row is above-mentioned to extract the intracorporal cleaning solution of people out.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
