Problems solved by technology

[0003] In order to detect the liquid level of the infusion, some devices install the liquid level sensor inside the infusion tube for detection. Although the effect is very good, the contact between the sensor part and the liquid medicine is likely to contaminate the liquid medicine and destroy the composition of the liquid medicine , affecting treatment
Others are detected by infrared rays, which are susceptible to interference, troublesome installation, and low reliability

Abstract

The invention provides a liquid level automatic alarm device in medical transfusion. The device is characterized in that the device comprises a power supply, an LED1 indicating lamp, a sound-light alarm module, a pulse frequency detection module, a capacitance liquid level sensor, a single-chip microcomputer, and a reset key. The device does not pollute solution, and is good in reliability, low in cost, and simple and convenient in installation operation. The device can rapidly and accurately determine that the solution is completely transfused, and gives out a sound-light alarm signal to prompt a nurse to dispose in time, thereby greatly reducing the number that a nurse rushes about back and forth, reducing labor intensity of the nurse and cost of looking after a patient, and reducing psychological burdens. The device has better guarante for treatment of patients.

Description

technical field [0001] The invention relates to an automatic alarm device for medical infusion liquid level, which is mainly used in the field of medical drip infusion level detection and other liquid level detection fields. Background technique [0002] At present, patients in most hospitals and clinics still have to rely on medical staff or themselves to pay attention to the infusion process when administering drip infusion, and call medical staff to come to deal with it when the infusion is completed or when the medicine bottle needs to be replaced. This method consumes manpower and financial resources, and is not conducive to timely operation, especially at night or when the patient is unconscious. Treatment, which can be life-threatening in severe cases. Therefore, a simple and efficient automatic alarm device for patient infusion is designed, and when a bottle of medicinal liquid is about to be infused, an alarm signal is sent in time to remind medical staff to deal w...
