A blood vessel automatic thrombolysis system

Abstract

The invention relates to an automatic blood vessel thrombolysis system. The automatic blood vessel thrombolysis system is characterized by comprising a liquid medicine pushing part and a liquid medicine suction part. The liquid medicine pushing system mainly comprises a pushing pump, a pushing pipeline provided with a spiral liquid outlet, a non-return valve, a liquid medicine supplement cavity and the like, and the liquid medicine suction system mainly comprises a suction pump, a suction pipeline, a non-return valve, a discharge container and the like. When the automatic blood vessel thrombolysis system works, the liquid medicine pushing system draws thrombolysis liquid medicine, and pushes the thrombolysis liquid medicine into the pushing pipeline, and injects the thrombolysis liquid medicine to the thrombus position through the spiral liquid outlet. After a certain thrombolysis period of time, the liquid medicine suction system works, thrombus dissolved matter generated by the thrombolysis process and residual liquid medicine are absorbed by the suction pump through the suction pipeline and the non-return valve, then the suction pump pushes the thrombus dissolved matter and the residual liquid medicine to the discharge container, and a circular thrombolysis operation is completed. According to the embolism case, the above thrombolysis process is repeated. The automatic blood vessel thrombolysis system can achieve automatic operation of thrombolysis, and can control injection and suction of thrombolytics accurately, and can guarantee standardization of thrombolysis surgery.

Description

technical field [0001] The invention relates to an automatic blood vessel thrombolysis system, in particular to the field of heart, brain and peripheral blood vessel thrombolysis treatment. Background technique [0002] The incidence of heart, brain, and peripheral vascular diseases continues to increase. At present, most of them are treated with thrombolytic drugs. For more severely blocked blood vessels, thrombolytic injection is often used clinically. The devices used are auxiliary devices such as interventional guide wires, catheters, and syringes. Through the superficial blood vessels, under the guidance of the interventional guide wire, guide the catheter to the thrombus site, and then use the repeated pulling action of the syringe plunger to repeatedly flush the thrombus with a thrombolytic agent to achieve the purpose of rapid thrombolysis. There are following problems and deficiencies in this method: [0003] 1. Due to the small diameter of the guide wire and the ...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the small diameter of the guide wire and the large viscous resistance of the liquid, the pushing and pulling force required to push and pull the syringe piston is relatively large, and repeated pushing and pulling by hand for a long time is prone to fatigue;

[0004] 2. Repeated manual push-pull operation is not easy to accurately control the flow rate of each wave, resulting in unstable thrombolytic speed, and when the impact force is too large, the plaque may even fall off and cause obstruction

[0005] 3. The push-pull time of each wave cannot be precisely controlled, which can also cause unstable thrombolysis speed

[0006] 4. Manual operation is limited by the operator's skills, physical strength and subjectivity, so that the operation process cannot be standardized, and the effect of thrombolysis operation varies greatly from person to person, and the effect is unstable
