[Design and application of a multiple combination portable auxiliary device for infusion].

Abstract

Intravenous infusion is an important route of drug therapy, and infusion safety is an important issue for medical staff. Long-term and multiple infusion routes at the same time bring inconvenience to patients. Multiple three-way switches in parallel infusion may lead to interruption of the liquid route, which can seriously endanger the life of patients. To address these clinical issues, medical staff from the School of Basic Medical Sciences of Hebei Medical University and the Emergency Department of the Second Hospital of Hebei Medical University designed a multiple combination portable infusion assistance device and obtained the National Utility Model Patent of China (ZL 2022 2 0226073.2). The device is mainly composed of adhesive tape sticker, fixed slots and pipelines, and also includes a three-way valve and a mixing chamber, and different modes of infusion assist devices can be selected according to clinical needs. The device is simple and convenient to operate, solves the problem of multiple liquid infusion blockages, improves the safety and comfort of infusion, and can meet the needs of liquid infusion in various clinical situations.
