Vena cava filter device capable of releasing thrombolytic drug

Abstract

A vena cava filter device capable of releasing a thrombolytic drug is characterized in that a drug release head with a plurality of irregular holes is arranged in the center of a filter, the drug release head and a drug conveying pipe are connected and arranged in a filter body connecting pipe, and one end of the drug conveying pipe is provided with a drug injection hole. According to the vena cava filter device, thrombi are stopped by the vena cava filter, the thrombolytic drug is injected into the drug conveying pipe in the a filter body connecting pipe through the drug injection hole, and if the thrombi are stopped by the vena cava filter, the thrombolytic drug is directly injected to the thrombi through the irregular holes; it is not needed that venipuncture is carried out on a patient again to achieve thrombolysis, so that secondary injuries to the patient are reduced and risks brought by venipuncture to the patient are avoided; the vena cava filter device has the dual effects of stopping the thrombi and achieving thrombolysis.

Description

technical field [0001] The patent of the invention belongs to medical devices, specifically a vena cava filter device capable of releasing thrombolytic drugs. Background technique [0002] In order to effectively prevent the occurrence of pulmonary embolism, a filter device is placed in the vena cava to intercept free emboli in the blood. This technology has been widely used in China. [0003] After the current vena cava filter intercepts the thrombus in the patient's body, the method of venipuncture and catheterization is usually used to inject thrombolytic drugs into the vein to treat the thrombus. For the treatment of thrombolysis by venipuncture catheter, patients not only have to suffer from the pain of secondary puncture, but also require medical staff to have skilled operating techniques. Since the catheter is placed in the vein, complications such as catheter-related infection and catheter blockage are particularly prone to occur. . Contents of the invention [0...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing vena cava filter can only intercept the thrombus in the vena cava, but cannot treat the thrombus. The patient needs to do a second venipuncture operation for the thrombus treatment, and bear the risk of the second puncture operation, and provides a structure A vena cava filter device capable of releasing thrombolytic drugs that is reasonable, reliable, easy to operate, and high in safety
