Abstract

The invention discloses a high-precision micro-injection pump and application of the high-precision micro-injection pump and relates to the technical field of medical instruments. The high-precision micro-injection pump solves the problems that an existing micro-injection pump is poor in adaptability and the stability is poor when syringes are clamped. The high-precision micro-injection pump comprises a shell, a display input module, a stepping motor pushing mechanism and a master control module and is characterized in that the shell is provided with a syringe tube handle clamping groove and a syringe tube bracket used for supporting a syringe tube in an attached mode, the shell is further provided with an elastic clamping mechanism, and the elastic clamping mechanism is matched with the syringe tube bracket and used for clamping and fixing the syringe tube; the elastic clamping mechanism comprises a first L-shaped support and a second L-shaped support which are arranged side by side; a displacement sensor for detecting the distance between the first L-shaped support and the second L-shaped support is arranged between the first L-shaped support and the second L-shaped support. According to the specifications of syringes, different specifications of syringe tube brackets, first clamping pieces and second clamping pieces are selected and matched, the sectional area of the syringe tube is calculated by the displacement sensor according to the distance between two different containing marks, the high-precision micro-injection pump is suitable for various specifications of syringes, the stability is good when the syringes are clamped and fixed, and the flow speed of fed medicine of the syringes can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to the structural improvement of a high-precision micro-injection pump and the method for improving the precision of infusion. Background technique [0002] As a common clinical treatment method, micro-syringe pump medication has been widely used in various fields of medical practice. [0003] The working principle of the micro-injection pump is based on the stepping motor as the power source. The system sends out control pulses to make the stepping motor rotate. The stepping motor drives the screw to rotate, and the screw drives the injection head on the transmission nut to move linearly, thereby pushing the syringe piston. The linear movement makes the liquid in the syringe flow in one direction, and the advancing speed of the liquid can be adjusted by setting the rotational movement of the screw, so as to adjust the given drug dose. At the same time, the speed measurem...
