Infusion bag reminding and speed limiting device

Abstract

Provided is an infusion bag reminding and speed limiting device. The infusion bag reminding and speed limiting device is characterized by comprising an infusion bag, a drip capsule and a drip tube; adetector and a speed limiter are connected through a connection line, the detector is clamped at the bottle mouth of the infusion bag, and the speed limiter is clamped on the drip tube; a light emitter and a light receiver are arranged on the portions, at the two ends of the bottle mouth of the infusion bag, on the detector and used for emitting and receiving light signals, and the speed limiter controls the flow speed of medicine liquor in the drip tube after receiving the signals of the detector; when the light emitter and the light receiver are arranged at the two ends of bottle mouth of the infusion bag, a light emitting element in the light emitter aslant emits light to the bottle mouth of the infusion bag. The infusion bag reminding and speed limiting device aims at avoiding the defect that people need to pay attention to new change of the medicine liquor in the infusion bag multiple times for a long time by themselves, and burdens of patients, patient families and nurses are reduced.

Description

technical field [0001] The invention relates to a reminder and speed limiter which can automatically send out an alarm and control the flow rate of the liquid medicine after the liquid medicine in the transfusion bag runs out. Background technique [0002] Existing infusion bottle mainly is divided into two big classes, and a class is bagged infusion bottle in soft bag, as polypropylene infusion bag, and a class is infusion bottle in rigid bottle, as glass infusion bottle. During the infusion process of the soft-bag infusion bottle, since the infusion bag can shrink, when the medicine in the bag drops into the drip bag through the upper dropper, the air pressure in the bag will be lower than the outside due to the decrease of the medicine in the bag. The outside atmospheric pressure will flatten the bag correspondingly, so that the air pressure inside and outside the bag will be the same. Therefore, the infusion bag is only provided with an upper dropper, and the medicinal ...

AI Technical Summary

Problems solved by technology

It is unrealistic for nurses or nurses to keep an eye on the progress of the infusion. Usually, a nurse or nurse has to take care of multiple patients in multiple wards at the same time. If there is no timely reminder, it is impossible to deal with it in time.
