Micro motor infusion pump

Abstract

The invention discloses a micro motor infusion pump which comprises an infusion board assembly and a motor driving device. The infusion board assembly comprises one-way valves, elastic pump tubes, an air elimination diaphragm and an impedance probe which are integrated on an infusion substrate; the liquid inlet channel and the liquid outlet channel of the infusion substrate are respectively connected with an infusion bag and the air elimination diaphragm; both ends of the liquid inlet channel and the liquid outlet channels are connected with two parallel pump tubes, and are respectively provided with the on-way valves; the air elimination diaphragm is integrated on the substrate, the cavity of the diaphragm is provided with a hydrophilic air barrier film, and the bottom of the lower cavity thereof is provided with an air elimination hole with an exhaust diaphragm; the impedance probe is arranged at a liquid outlet; and the microcomputer part swings through a swinging extrusion head to alternatively press the elastic pump tubes, so as to output the liquid in one way. The micro motor infusion pump integrates the one-way valve double pump tubes, the air elimination diaphragm and an impedance sensor, has the function of eliminating the gas contained in the liquid in the pump, can realize air volume ultra-limit alarm and blocking alarm, and has the advantages of micro-power, low power consumption, small size and convenient carrying.

Description

Technical field: [0001] The invention relates to a micro-motor blood transfusion pump technology. Background technique: [0002] Intravenous blood transfusion is the most commonly used clinical treatment. For gunshot wounds, puncture wounds, burns and other trauma, blood loss, and dehydration shock patients, pre-hospital emergency controlled rapid infusion of fluids is a very important rescue measure. At present, due to the limitation of various technical conditions, the controllable rapid blood transfusion device suitable for pre-hospital first aid and battlefield use has always been a problem. So far, there is no such product equipped with medical emergency teams inside and outside the military, resulting in the uncontrollable rapid infusion of liquid. , was forced to suspend the fluid infusion of the wounded, and it was difficult to carry out anti-blood loss and dehydration shock treatment. Although there are various controllable and accurate infusion pumps for hospital...

Problems solved by technology

At present, due to the limitation of various technical conditions, the controllable rapid blood transfusion device suitable for pre-hospital first aid and battlefield use has always been a problem. So far, there is no such product equipped with medical emergency teams inside and outside the military, resulting in the uncontrollable rapid infusion of liquid. , was forced to suspend fluid infusion for the wounded, making it difficult to carry out anti-blood loss and dehydration shock treatment

Although there are various controllable and accurate infusion pumps for hospital treatment, they cannot be used in pre-hospital first aid and battlefields because of their large size, weight, and high power consumption. Continuous liquid infusion requires AC power supply.

However, the existing pressurized infusion sets and portable infusion devices cannot fully meet the requirements of pre-hospital first aid, battlefield, etc. use
