In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a can handle pipe sheath that dialysis catheter blockked up, includes the pipe sheath main part, the pipe sheath main part cup joints the intubate section of connecting the dialysis catheter, pipe sheath main part left end is close to the setting of bifurcated pipe and straight tube section hookup location department on the dialysis catheter, pipe sheath main part right-hand member sets up in side opening left side on the dialysis catheter intubation section, pipe sheath main part and the inseparable laminating of dialysis catheter intubation section, be equipped with on the pipe sheath of pipe sheath main part left end and dialyse the matched with liner between the catheter intubation section outer wall, the left end both sides of pipe sheath main part are equipped with fixed the knot.
As an improvement, the diameter of the inner wall of the right end pipe of the catheter sheath main body is smaller than that of the inner wall of the left end pipe of the catheter sheath main body.
As an improvement, the hardness of the catheter sheath main body is greater than that of the intubation section of the dialysis catheter.
As an improvement, the catheter sheath body is made of medical polymer materials.
As an improvement, the catheter sheath body has an exposed length of 2-4cm after being placed, so that the left end of the catheter sheath body can be clamped by a blood supply forceps.
Compared with the prior art, the utility model the advantage lie in: at present, when the phenomenon of tube blockage appears clinically, the dialysis machine can give an alarm in time, and then the tube is sealed by heparin saline or urokinase, but the problems can not be solved in many times, and risks such as thrombus falling can also be caused. The catheter sheath adopted by the utility model is made of high molecular material, has smooth surface and good tissue compatibility with the body; meanwhile, the catheter sheath is simultaneously placed into the body along with the dialysis catheter, the catheter can be pulled out when the catheter is blocked, and the catheter can be placed into the body again through the catheter sheath after the catheter is passed through again, so that the problem of catheter blockage is solved; in addition, the problem of catheter blockage can be solved without replacing the catheter and the puncture site. The utility model discloses rational in infrastructure, effectual solution dialysis catheter blocks up the problem, prevents to put the adverse reaction that the pipe brought to patient again, suitable extensive using widely.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The utility model discloses when concrete implementation, a can handle pipe sheath of dialysis catheter jam, including pipe sheath main part 1, pipe sheath main part 1 cup joints the intubate section of connecting dialysis catheter 2, 1 left end of pipe sheath main part is close to the setting of bifurcated pipe and straight tube section hookup location department on the dialysis catheter 2, 1 right-hand member of pipe sheath main part sets up in 3 left sides of side opening on the 2 intubate sections of dialysis catheter, pipe sheath main part 1 closely laminates with the 2 intubate sections of dialysis catheter, be equipped with on the 1 left end sheath pipe of pipe sheath main part and dialyse matched with liner 4 between the 2 intubate section outer walls of catheter, the left end both sides of pipe sheath main part 1 are equipped with fixed 5 of detaining.
The diameter of the inner wall of the right end pipe of the catheter sheath main body 1 is smaller than that of the inner wall of the left end pipe of the catheter sheath main body 1, the hardness of the catheter sheath main body 1 is larger than that of the intubation section of the dialysis catheter 2, the catheter sheath main body 1 is made of medical high polymer materials, and after the catheter sheath main body 1 is placed in the intubation section, the exposed length is 2-4cm, so that a left end of the catheter sheath main body can be clamped by a pair of blood supply forceps.
The utility model discloses a theory of operation: the catheter sheath is slightly thicker than and shorter than the dialysis catheter, the tail end of the catheter sheath is positioned at the near end of the side hole of the dialysis catheter and is tightly attached to the dialysis catheter, and blood backflow is avoided. The sheath opening is provided with a liner which is tightly attached to the wall of the catheter, and when the dialysis catheter is placed, the catheter sheath is sleeved outside the catheter and is placed in the blood vessel, and the catheter sheath is provided with a fixing device. When the blockage is found, the dialysis catheter can be taken out with a syringe under negative pressure under the aseptic operation condition, and the outer end of the sheath tube can be temporarily clamped by forceps during taking out, so that the blood can be prevented from flowing out.
