Abstract

The invention provides a force-controllable anti-infection and anti-radiation intelligent treatment device characterized in that a needle cylinder shell (1) and a base plate (2) can be fixed and can also slide; a needle cylinder piston (3) is arranged; horizontal parts A and B of a limiting semi-ring (4) are provided with holes, screws penetrate through the holes, the lower ends of the screws are welded to the base plate, springs (5) are arranged outside the screws, the screws penetrate through the gaskets (6), pointers are fixed to the gaskets (6), the lower end of a ruler (8) is fixed to the base plate, nuts (9) are matched with the screws, and the structure of the position B is the same as that of the position A. The electric push rod system is characterized by comprising a static part (10), a positioning end (11) fixed with the base plate through the screws, a movable push head (12), a fixed component (13), a motor (14) and an internal variable speed transmission mechanism (15). The control system is characterized in that a single-chip microcomputer is fixed with a base electrode, the output end of the single-chip microcomputer is connected with the input end of a driver, and the output end of the driver is connected with the motor.

Description

technical field [0001] The invention relates to the field of intelligent medical equipment. Specifically: there is a kind of electric push rod: it is the device that motor, gear, push rod are integrated. The motor rotates forward, and the effect is that the push head directly pushes the syringe piston forward for injection. The syringe shell and the base plate can be fixed and slide (to prevent damage from excessive thrust). The special mechanical device limits excessive thrust and protects the patient. . Background technique [0002] The speed of manual injection is not constant, and the strength is not easy to control. In the case of radiation and infection, doctors are in danger. There is an urgent need for an injection device: constant injection speed, controllable and limited force, no danger of excessive thrust, automatic and precise control, suitable for radiation and infection occasions. But do not see relevant product and patent to come out so far. Contents of ...
