Abstract

The invention relates to a three-in-one venous transfusion monitoring system, which is used for assisting a venous transfusion process, can be hung or fixed on the conventional transfusion bracket, realizes alarm reminding when transfusion is finished, automatic dripping speed regulation and control and pulse monitoring in a transfusion process and can remind a patient when abnormity occurs at the end of or during the transfusion and inform a nurse station in a wired or wireless radio frequency transmitting mode for in-time treatment. The monitoring system comprises three subsystems, namely, a transfusion alarm subsystem, a transfusion dripping speed control subsystem and a transfusion pulse monitoring subsystem which are used together so as to fully detect the venous transfusion process and can be used separately in different application occasions. Therefore, the monitoring system has high practicability. Liquid level is detected innovatively in a capacitance sensor mode, so that high accuracy is achieved.

Description

technical field [0001] The invention belongs to the field of medical devices and is used for assisting the intravenous injection process. It can be hung or fixed on the existing infusion support to realize the three-in-one function of alarm reminder at the end of injection, automatic drip speed adjustment control and pulse monitoring during the infusion process. Or when there is an abnormality in the process, it can not only remind the patient in time, but also notify the nurse's desk through wired or radio frequency transmission, so as to deal with it in time. Background technique [0002] The following problems often exist in the existing intravenous infusion process: [0003] 1. Patients / nurses need to always pay attention to the remaining liquid medicine, especially for patients and nurses in the night ward, this is a kind of physical and psychological torture; [0004] 2. The infusion speed is often difficult to follow the doctor's advice. Generally, the infusion speed...
