Push sleeve applicable to intravenous thrombolysis catheter

Abstract

The invention provides a push sleeve applicable to an intravenous thrombolysis catheter. The push sleeve comprises a push sleeve tube body. The length of the push sleeve tube body is smaller than that of the intravenous thrombolysis catheter. The top end of the push sleeve tube body is provided with a marker line. The intravenous thrombolysis catheter is sleeved with the push sleeve tube body. After the intravenous thrombolysis catheter is implanted behind a blood clot, the push sleeve tube body is pushed, the length of a dosing part of the thrombolysis catheter is adjusted according to the marker line on the push sleeve tube body so that the length of the dosing part is identical to that of the blood clot, thrombolytic drug can be released more accurately and effectively, and the thrombolysis efficiency is improved; meanwhile, for a patient which accepts thrombolytic therapy once more, a thrombolysis catheter of a new specification does not need to be implanted again, and a doctor just needs to push the push sleeve tube body and determine a reasonable dosing interval; as a result, medical cost is lowered, the working intensity of medical workers is reduced, the problem of multiple specifications of the hrombolysis catheters is solved, and the push sleeve is reasonable, effective and convenient to operate.

Description

[0001] technical field [0002] The patent of the invention belongs to the field of medical devices, specifically a push sleeve that can be applied to an intravenous thrombolysis catheter. Background technique [0003] After the existing intravenous thrombolysis catheter is inserted into the thrombus, it releases drugs for thrombolysis through the administration hole of the catheter. Due to the different specifications of the administration interval of the thrombolytic catheter, when the size of the thrombus in the patient's body changes, it is necessary to re-insert the intravenous thrombolytic catheter of different specifications for treatment. Patients not only have to bear the pain and risk of secondary puncture and catheterization, but also increase the workload of medical staff. Contents of the invention [0004] The purpose of the present invention is to solve the problem that when the size of the thrombus in the patient's body changes, it is necessary to re-insert...
