Problems solved by technology
[0003] When dredging, the guide wire needs to be moved back and forth, and the inner diameter of the dialysis catheter is relatively thicker than the guide wire, so the blood will flow out from the rear end of the dialysis catheter along the guide wire; the outflow of blood will cause harm to the human body; therefore, it is necessary to design a A device that is attached to the end of the dialysis catheter to prevent blood from flowing out when a guide wire is needed to dredge it, so as to solve the above problems

Embodiment 2
[0024] On the basis of Embodiment 1, in order to make the performance of this device more optimized, as Figure 5 and 6 As shown, a guide wire 5 is slidably installed between the first communication hole 12 and the second communication hole 13, and the guide wire 5 can pass through the dialysis catheter 4 for dredging; the end of the guide wire 5 inserted into one end of the sheath tube body 1 is set There is a contact seat 14, and the bottom of the contact seat 14 is provided with a spherical contact 15. The setting of the spherical contact 15 can effectively prevent the inner wall of the guide wire 5 from being scratched when it is inserted into the dialysis catheter 4.

The invention relates to the technical field of sheath canal structures, and discloses a sheath canal connected with a deep vein dialysis catheter. The sheath canal comprises a sheath canal body, a communicating pipe and a dialysis catheter, wherein the communicating pipe is arranged on the side face of the sheath canal body; external threads are arranged at the bottom of the sheath canal body and one end of the dialysis catheter; a nut is arranged on the external thread of the sheath canal body; and the sheath canal body and the dialysis catheter are connected together through the nut. The sheath canal body and the dialysis catheter are connected in a threaded mode, the sheath canal body and the dialysis catheter can be conveniently assembled and disassembled through the threaded connection mode, and the efficiency for dredging internal blockage condition of the dialysis catheter through a guide wire can be improved; and partition plates and rotating plates are arranged in the sheathing canal body, so that the guide wire can be guided and supported, and blood can be prevented from flowing out.
Description
technical field [0001] The invention relates to the technical field of sheath tube structure, in particular to a sheath tube connected to a deep vein dialysis catheter (temporary or long-term). Background technique [0002] In emergency and clinical rescue, deep venous catheter is an indispensable and important tool. Its puncture site can choose femoral vein, subclavian vein or internal jugular vein; its main purpose is to provide patients with continuous or intermittent intravenous infusion and monitor central vein. Pressure, central venous nutrition injection, infusion of hypertonic or irritating solution, blood transfusion or collection of blood samples, etc.; when using a deep vein dialysis catheter for dialysis, the back end of the dialysis catheter is connected to the instrument, and the front end is inserted into the organ, and blood clots block the dialysis At the front end of the catheter, a guide wire needs to be used. At this time, the rear end of the dialysis cat...
