Abstract

The invention provides an anti-radiation medicine liquid injection robot with the controllable liquid injection speed. The anti-radiation medicine liquid injection robot is composed of two parts, including an intelligent controller and a mechanical component, wherein the mechanical component is characterized by being composed of the following parts: a base plate (1), a linear guide rail (2) fixed to the edge of the base plate, a slider (3) capable of sliding on the guide rail, a motor (4), a motor bracket (5) fixed to the base plate, a screw rod (6) with threads, a coupler (7) arranged between the screw rod and a motor shaft, a nut (8) matched with the screw rod, a bracket (9) fixed to the slider (3) and the nut (8), a push rod (10) fixed to the slider, a pressure sensor (11) at the front end of the push rod, a pushed end (12) of an injection pump piston, a horizontal semicylindrical injection pump limiting groove (13), arc-shaped limiting cover boards (14) provided with hinges and being capable of being turned over at the upper part of the injection pump, an injection pump (15), a motor rotation angle sensor (16), and an intelligent controller (17) positioned on the same straight line with the guide rail and the motor.

Description

technical field [0001] The invention relates to the field of intelligent medical equipment. Specifically, it is a device that drives the piston of the syringe pump under the intelligent control of a single-chip microcomputer, with precise and controllable speed, and realizes the anti-radiation injection liquid in the environment of X-ray radiation. Background technique [0002] Various examinations performed by the imaging department on patients require continuous and controlled injection of contrast agents into blood vessels. The speed needs to be controllable, and medical personnel need to be protected from radiation damage. But so far no relevant medical equipment and patents have come out. Contents of the invention [0003] The present invention is a radiation-proof liquid medicine injection robot with controllable injection speed, which is invented for the above-mentioned needs. It is composed of an intelligent controller and a mechanical component. The mechanical c...
