Description

An infusion set and monitoring device based on the infusion set

technical field

The present invention relates to the technical field of medical devices, and more particularly to an infusion set and a monitoring device based on the infusion set.

Background technique

At present, clinical infusion sets are composed of cork puncture device, infusion hose, drip pot, flow regulator and venous needle. Air bubbles are generated in the hose and need to be detected and eliminated in time, otherwise the air bubbles entering the patient's venous blood vessels may cause air stagnation and endanger life.

There are three kinds of exhaust methods usually used: the upper bomb method, the lower row method and the acupressure method. The bombing method is mainly used to enter a small amount of gas into the infusion set. For a large amount of gas entering in this case, the bombing method is very laborious and time-consuming. The lower row method needs to be pulled out, the infusion will be stopped immediately, and the infusion will be continued after the air bubbles are removed. The acupressure method is to close the regulator, gently squeeze the Murphy dropper with your hand, so that the liquid in the Murphy dropper reaches 1/2 to 2/3, place the index finger of the left hand under the air section, and wrap the infusion tube tightly around the infusion tube. On the left index finger, twist upwards in sequence until the air bubbles are pressed into the Murphy dropper. The operation is complicated.

A series of operations such as inverting the drip bucket or pinching the catheter are required to remove excess gas. If the operation is not performed properly, a large amount of liquid and gas will be mixed into the lower catheter to form bubble liquid, which will affect the infusion process. If it is not found due to negligence, it may cause harm or even fatal to the human body. The process of removing these air bubbles is cumbersome and reduces labor efficiency. The nurse on duty must inspect every once in a while, and the patient needs to call the nurse in time before the end of the drug drip. If it is not found in time when the drug is instilled, the air enters the infusion drip tube, which may cause vascular embolism of the patient and cause serious medical accidents.
