Gravity transfusion pump

Abstract

The invention discloses a gravity transfusion pump with high flow velocity control accuracy. The gravity transfusion pump comprises a main engine and a detection and control apparatus, wherein the main engine comprises a master movable power supply, a shell with a suspension function, a weighing sensor, a master control circuit board, a liquid crystal display screen, a master Bluetooth module and keys; the detection and control apparatus comprises a detection and control box, a slave movable power supply, a slave control circuit board, a bubble detector, a flow velocity controller, a slave Bluetooth module, a motor zero switch and a pump door switch; the master movable power supply, the weighing sensor, the master control circuit board, the liquid crystal display screen, the master Bluetooth module and the keys are arranged in the shell; and the slave movable power supply, the slave control circuit board, the bubble detector, the flow velocity controller, the slave Bluetooth module and the pump door switch are arranged in the detection and control box. The gravity transfusion pump disclosed by the invention has the advantages of high transfusion precision, small overall structure, simplicity and convenience in operation and use and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a high-precision gravity infusion pump that obtains the infusion rate by weighing the liquid medicine, solves the infusion error and makes corrections in time. Background technique [0002] The existing peristaltic infusion pump drives the medicinal liquid into the blood vessel by squeezing the infusion tube to complete the infusion task. The accuracy of the flow rate (ml / h) during the infusion process is related to the therapeutic effect and even life safety. Due to the difference in elasticity, ambient temperature, service time and external dimensions of the infusion tube (mostly made of PVC material), the same infusion pump uses different manufacturers or different batches of infusion devices with different flow rate accuracy. The accuracy of the flow rate is also different from that of the long-term use condition. Therefore, the flow rate error of the existing infusi...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem that the existing infusion pump is affected by pipeline elasticity, external dimensions, ambient temperature and service time, and the accuracy of the flow rate is not high, the present invention proposes a gravity infusion pump, which can avoid the influence of the above factors and ensure the accuracy of the infusion flow rate
