Embodiment Construction

[0016] In order to deepen the understanding and knowledge of the present invention, the present invention will be further described and introduced in conjunction with the accompanying drawings.

[0017] Such as figure 1 with 2 As shown, a new type of intravenous infusion sensor includes a sensor unit and a microcontroller, the sensor unit is connected to the microcontroller through a data line, the sensor unit includes an accelerometer and a gas flow meter, wherein the accelerometer and the gas flow meter Both are detachable and connected to the microcontroller through the data cable. When in use, the accelerometer is clamped on the observation bottle of the infusion tube to monitor the vibration of each drop of liquid medicine dripped into the observation bottle of the infusion tube in real time It converts the continuously stable vibration signal into a continuously stable droplet electrical signal and transmits it to the microcontroller through the data line. When the droplet ...

Abstract

The invention relates to a novel intravenous injection transfusion sensor. The sensor comprises a sensor unit, a microcontroller, a sound-light alarm unit and a power supply. The sensor unit and the sound-light alarm unit are connected to the microcontroller through data cables. The power supply supplies power for the sensor unit, the sound-light alarm unit and the microcontroller, wherein the sensor unit comprises an accelerometer and a gas flowmeter. The accelerometer monitors a vibration signal of every drop of drug liquid dropping in an infusion tube observation bottle in real time, and the gas flowmeter monitors an air supply pulse signal of an air supply opening of an infusion bottle or an infusion bag in real time. The microcontroller synthetically calculates related signals and finally generates an infusion ending signal. Once receiving the infusion ending signal, the sound-light alarm unit instantly generates a sound-light alarm signal so as to remind a patient or a medical worker that the drug liquid in the infusion bottle or infusion bag drips off, and the infusion bottle or the infusion bag is replaced or an infusion is stopped. The novel intravenous injection transfusion sensor has dual monitoring insurance, monitoring is precise and no radiation energy is generated to affect delivery of the drug liquid.

Description

Technical field [0001] The invention relates to the technical field of sensors, in particular to a sensor suitable for monitoring of intravenous injection and infusion, in particular to a high-precision intravenous infusion sensor. Background technique [0002] When patients have infusions, they often rely on nurses' manual inspections or patients and their families to monitor the infusion bottles, which results in patients not being able to rest at ease and requiring family members to stay nearby. In order to make the intravenous infusion monitoring process of the infusion bottle electronic, information and intelligent, there are infusion monitoring sensors that use the principle of gravity measurement, photoelectric measurement and capacitance, etc., by using these sensors to monitor the infusion of the infusion bottle. It realizes the real-time sensing and monitoring of the infusion process. At the same time, the infusion monitoring sensor is also an important part of the intr...
