Injection pump with whole-process infusion safety detection and near-space detection structure

Abstract

The invention relates to an injection pump with a whole-process infusion safety detection and near-space detection structure. The injection pump comprises a rack, a motor and a syringe; the motor is connected with a screw rod through a speed reduction mechanism, the screw rod is matched with a clutch nut, the clutch nut is connected with a push rod, the push rod is connected with the syringe through a push head, the clutch nut is provided with a photoelectric coupler, and the rack is provided with light blocking pieces matched with the photoelectric coupler. The injection pump has the advantages that the novel structure formed by combining the photoelectric coupler and a set of light blocking pieces different in width and interval is adopted, the structure is simple, the reliability is high, and the cost is low; whether or not a transmission system of the injection pump loses efficacy can be monitored in the whole process, and the infusion safety is improved; the multi-position detection of the tail end is achieved, and the near-space alarming and infusion completion alarming reliability of the injection pump is improved.

Description

technical field [0001] The invention relates to the field of syringe pumps, in particular to a syringe pump with a light-sensitive infusion process safety and near-air detection module. Background technique [0002] The micro-injection pump is a medical device used to precisely control the infusion volume of the medicinal solution in the syringe, and is often used in the ICU ward. Conventional syringe pumps are generally equipped with a near-air detection device. When the liquid medicine is about to be infused, the sensor will be triggered, and the syringe pump will send out an alarm to remind medical staff to change the medicine or take other measures. Full-process safety detection is only equipped on high-end syringe pumps, which can detect failures in the infusion process in time, but the price of full-process sensors is relatively high, and low-end equipment is rarely equipped. Contents of the invention [0003] The present invention aims to solve the above-mentioned ...
