Abstract

The invention discloses a device assisting in injection. The device comprises a supporting rod whose longitudinal section is in an arc shape; a notched circular ring a and a notched circular ring b are sequentially arranged in the length direction of the supporting rod; one ends of the notched circular ring a and the notched circular ring b are hinged to the supporting rod, and the other ends arein adsorption connection with the supporting rod through magnets; the notched circular ring a and the notched circular ring b are parallel to each other and are perpendicular to the supporting rod; and a round wheel is fixedly connected to the highest position of the outer surface of the notched ring a. According to the invention, the problems of high difficulty in injecting liquid into in-vivo micro blood vessels and low injection success rate in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of precision auxiliary devices for medical treatment and scientific research, and in particular relates to a device for assisting injection. Background technique [0002] Generally speaking, micromanipulation is required for the injection of liquid in tiny blood vessels or catheters in the body, which has great technical requirements for the operator, and the success rate is low; Difficulty in operation, especially for the injection of liquid in tiny blood vessels during surgery and the collection of samples in scientific research experiments. Contents of the invention [0003] The purpose of the present invention is to provide a device for assisting injection, which solves the problems of high difficulty and low success rate of injecting liquid in tiny blood vessels in the body existing in the prior art. [0004] The technical solution adopted in the present invention is, a device for assisting injection...
