Description

An Intelligent Infusion Monitoring System

technical field

The utility model relates to the field of medical equipment, in particular to an intelligent transfusion monitoring system.

Background technique

Infusion is also known as drip or hanging water. It is a large dose that is infused into the body by intravenous infusion, and the administration is more than 100ml at a time, and it is an injection. Usually packaged in glass or plastic infusion bottles or pouches without preservatives or bacteriostats. When in use, the drip rate is adjusted through the infusion set, and it enters the vein continuously and steadily to replenish body fluids, electrolytes or provide nutrients. Because it is used in large amounts and directly enters the blood, the quality requirements are high, and the production process is also somewhat different from small-needle injections.

Traditionally, there is no monitoring device for intravenous infusion for patients. The patient or the family members who take care of the patient need to keep an eye on whether the injection is used up. If it is used up and not replaced in time, it will cause hidden dangers and harm to the patient's body. Even if the patient is concerned about the use of the injection, sometimes the nurse is not around and needs to notify the nurse. Because the patient is inconvenient to move, it is also a very troublesome thing. Moreover, it is very inconvenient to remind the nurse every time.
