Description

Infusion device and infusion method capable of removing bubbles automatically

Technical Field

The invention relates to the technical field of medical instruments, in particular to an infusion device and an infusion method capable of removing bubbles automatically.

Background

Intravenous infusion is a nursing activity which is most clinically applied, is a small problem in the whole medical treatment process, and brings unnecessary pain to patients if the venous infusion is neglected. In clinical practice, when a patient is treated by infusion, air bubbles are often generated in an infusion tube, and the generation of air bubbles is caused by various factors, for example: environmental temperature differences, drug characteristics, tubing defects, and improper operation, among others. Air is strictly prevented from entering the vein from the iv route if air bubbles enter the patient's venous vessels through the tubing which can cause an air lock and be life threatening.

The air bubble problem is not negligible and always a major concern of doctors and patients because of the large clinical use of products such as infusion tubes. The bubble has multiple reasons, and the most is remaining gas in the transfer line terminal filter, but the other one is because when the liquid medicine gets into the drip cup from drip cup top transfer line, because the drip cup is in on the same axis with the transfer line, can be with gas pressure in the liquid medicine under the inertial force effect, produces the microbubble, and the microbubble can adsorb on the pipeline way wall, gathers gradually, forms the big bubble.

Clinically, there are three methods of exsufflation we commonly use: springing up, springing down and finger pressing. The spring-up method is mainly used for introducing a small amount of gas into the infusion apparatus, and the spring-up method is very labor-consuming and wastes time for introducing a large amount of gas under the condition. The downward discharge usually results in waste of the liquid medicine, and is not suitable for the administration of the more expensive liquid medicine. The finger pressing method is to close the regulator, slightly press the Murphy's dropper with a hand to make the liquid medicine in the Murphy's dropper reach 1/2-2/3, place the left index finger below the air section, tightly wind the infusion tube on the left index finger, and wind upwards in sequence until the air bubbles are pressed into the Murphy's dropper.
