Dependable ward transfusion dripping-speed monitor

Abstract

The invention discloses a dependable ward transfusion dripping-speed monitor. The dependable ward transfusion dripping-speed monitor comprises a shell and a circuit part; the shell is provided with a dripping cup cavity; the upper end of the dripping cup cavity is provided with a limiting plate; two sides of the dripping cup cavity are provided with two routes of detecting devices consisting of a helium-neon laser and a phototriode; the collector electrode of the phototriode is connected to the reverse input end of an operational amplifier by a resistor R5, and the reverse input end of the operational amplifier is connected with a power supply by a potentiometer R6; the base electrode and the collector electrode of a triode Q1 are respectively connected with the transmitting electrode and the collector electrode of the phototriode; and the output end of the operational amplifier is connected with the input end of a first single chip. The transfusion dripping-speed monitor is capable of, through installing two routes of detecting devices, effectively and accurately measuring the transfusion dripping-speed, ensuring the accuracy of the measuring data. The monitor has novel, scientific and rational detection principle, reliable and accurate detection result, strong dependability, and obvious beneficial effect, and is promoted and applied conveniently.

Description

technical field [0001] The present invention relates to a credible ward transfusion drip speed monitor, more specifically, to a credible ward that can effectively fix the monitor and ensure the reliability of the detection results by setting two detection devices. Infusion drop rate monitor. Background technique [0002] In clinical medicine, although intravenous infusion is widely used, the commonly used infusion tool is still the traditional Mufei's infusion set, and it is mainly controlled by manual monitoring. During infusion, it is necessary to hang the infusion bottle (bag) on ​​the infusion rack or higher than the puncture site of the patient, and use the potential difference to inject the medicinal liquid into the patient's body. Manually adjust the pulley on the infusion set to control the infusion rate based on experience. During the infusion process, nurses need to continuously inspect, and the patient or accompanying staff will observe the remaining amount of l...

Problems solved by technology

After investigation and analysis, the reason for the lack of popularization is that the reliability of the system is not sure, and it is worried that if the abnormality of the components is not found during use, and misoperation occurs, it may cause medical accidents. After all, medical accidents are no small matter. Human life is at stake
