Infusion alarm device

Abstract

The invention provides an infusion alarm device. The infusion alarm device comprises a shell, a sensor, a motor with an eccentric wheel and a circuit board, an accommodating cavity of a drip cup is formed in the shell, communicating channels are further formed in the two ends of the accommodating cavity, the sensor is positioned in the accommodating cavity, weak vibration signals generated when liquid drops drop on the liquid surface in the drip cup during infusion are collected, the circuit board is fixed to the shell and performs signal transmission with the sensor, the circuit board comprises a microcontroller, a buzzing circuit electrically connected to the microcontroller and a motor control circuit, the buzzing circuit is provided with a buzzer, and the motor is controlled by a motorcontrol circuit to act, so that an eccentric wheel of the motor is clamped into the channel communicated with the accommodating cavity. According to the invention, the dropping number and dropping speed of dropping liquid can be accurately monitored, and a user and a nurse can be accurately informed of the dropping time length of the dropping liquid. When an exception occurs, the patient and thenurse can be notified in time; and after liquid dropping is finished, the nurse and the patient are informed that infusion is finished. Meanwhile, the motor automatically clamps an infusion tube to prevent infusion blood return.

Description

technical field [0001] The invention relates to an alarm device, in particular to an infusion alarm device applied in the medical field. Background technique [0002] Infusion, also known as intravenous drip or hanging water, is a commonly used treatment method in medical treatment, and a large dose of injection is injected into the patient's body through intravenous drip. Generally, the infusion time is long, and the height of the infusion bag is required to be higher than the heart pressure of the human heart, so the infusion recipient needs to sit or lie down. In the prior art, the person receiving the infusion, the nurse or relatives need to keep an eye on the remaining amount of the infusion bag, and call the medical staff before the remaining amount of the infusion bag is over. They often miss the time because of distraction, resulting in blood reflux during the infusion process. In other cases, the health of the infused person is endangered, and even life safety is e...
