Ultrasonic alarm for pipe liquid level and alarm method thereof

Abstract

The invention discloses an ultrasonic alarm for a pipe liquid level and an alarm method thereof. A transmitting terminal ultrasonic transducer and a receiving terminal ultrasonic transducer are adopted for being oppositely and tightly fitted to the outer surface of the side wall of a pipe separately, the plane where the height centers of the transmitting terminal ultrasonic transducer and the receiving terminal ultrasonic transducer are located is an alarm liquid level, ultrasonic waves are focused into the pipe through a sound lens, the alarm is used as a low-liquid-level alarm, when liquid in the pipe is located above the alarm liquid level, ultrasonic wave signals are transmitted to the receiving terminal ultrasonic transducer through the liquid, and the ultrasonic transducer is poweredoff; when the liquid in the pipe is lower than the alarm liquid level, the ultrasonic wave signals which are received by the receiving terminal ultrasonic transducer are extremely weak, weak electricsignals are transmitted to an ultrasonic adjuster at this moment, when the liquid level in the pipe is lower than a logical threshold value, the ultrasonic transducers are powered on, an alarm powersource is started up, and the alarm gives out an alarm. According to the ultrasonic alarm, by using the attributes of the ultrasonic waves, the liquid level can be precisely monitored online in real time, an alarm can be automatically given out when the liquid level is not in a safety range, the input condition of the liquid is effectively monitored, and accordingly the liquid conveying safety isguaranteed.

Description

technical field [0001] The invention relates to an auxiliary device for medical equipment, in particular to an ultrasonic alarm device for liquid level in a pipeline and an alarm method thereof. Background technique [0002] During infusion in the hospital, medical staff, patients and their families need to pay attention to whether the liquid in the infusion tube has been dripped out. If the liquid has been dripped out, and the treatment behaviors such as replacing the new medicine or pulling out the needle in time are not taken in time, it is very easy to cause the patient to return blood, etc. occurrence of a dangerous situation. The number of patients visiting hospitals in our country is on the rise. Many hospitals often experience a shortage of beds. Even in special periods, hospital beds are vacant, and patients need to be placed in the corridors for infusion. In this case, the working pressure and intensity of the medical staff are too high, and they cannot pay attent...

AI Technical Summary

Problems solved by technology

In this case, the working pressure and intensity of the medical staff are too high, they cannot pay attention to the patient's infusion situation in time, and the probability of accidents is increased, so the safety of the patient cannot be fully guaranteed.

In clinical practice in our country, almost all the medical staff, family members accompanying the bed or patients are responsible for observing the infusion of liquid, and the method of monitoring infusion with automatic alarm equipment is not used to ensure the safety of infusion
