Abstract

The invention discloses a syringe-microinjection-type infusion device based on shape memory alloy driven and a method thereof. A baffle, a first fixing plate and a second fixing plate are arranged on a base plate. Positioning holes are formed on a support plate and the baffle. Semi-cycle fixing grooves are formed on the first fixing plate and the second fixing plate. A stopping block is arranged in the middle of a push rod. Two sides of the stopping block are provided with a shape memory alloy spring and a reset spring. The end, with the reset spring mounted on, of the push rod penetrates the positioning hole on the baffle and contacts with a disposable syringe. The disposable syringe is placed in the semi-cycle fixing grooves of the first fixing plate and the second fixing plate, and is fixed on the first fixing plate and the second fixing plate through a first clamp and a second clamp. The end, with the shape memory alloy spring mounted on, of the push rod penetrates the positioning hole on the support plate which is fixed on the base plate through a bolt. The syringe-microinjection-type infusion device has the advantages that structure is simple, no noise is produced, size is small and the like, and is adaptable to micro-drug injection and the like.

Description

technical field [0001] The invention relates to an infusion device for micro-injection of medicines, in particular to a syringe micro-injection infusion device driven by a shape memory alloy and a method thereof. Background technique [0002] An infusion device generally refers to an intelligent infusion device that replaces ordinary gravity infusion with a micro motor and can precisely control the infusion speed. It can monitor the whole process of infusion status, and when there are abnormal conditions such as pipeline blockage and air bubbles, it can quickly and automatically close the infusion channel to prevent safety accidents. However, common micro-motor infusion devices have problems such as complex system, high cost, and unstable system. [0003] At present, about 50-60 million people in the world use infusion devices for treatment every year. The annual sales of infusion devices in the global market have exceeded 100 billion US dollars. Infusion device products ha...
