Abstract

The most common screening techniques to diagnose a patient’s illness are blood collection and intravenous procedures. To find a collection or injection site, conventional blood collection support tools, such as latex tubing and buckle-type tourniquets, are generally used to compress the patient’s blood vessels. This conventional passive method has significant problems such as latex allergy, vulnerability to site contamination and potential bloodstream infection, and physical damage due to improper use. To overcome the disadvantages of conventional blood collection support tools, an automatic tourniquet with a high-elasticity biocompatible strap was constructed. The automatic tourniquet is designed to automatically adjust the strap length using a motor to control the pressure according to the body dimensions of patients. In order to evaluate the performance of the automatic tourniquet, blood flow characteristics were analyzed using an ultrasound measurement system. The results demonstrated that the automatic tourniquet showed better performance compared with those of other blood collection support tools.

Summary

Introduction

Medical technologies have attracted much attention due to rapid technological development. Conventional blood collection support tools such as latex tubing and buckle type-tourniquets are used to compress the patient’s blood vessels [1,2,3,4,5,6,7,8]. These conventional blood collection methods are operated using passive methods in which medical staff directly apply the tourniquet to the patient’s limb. Long-term use of tourniquets can lead to physical damage such as hemolysis due to blood vessel compression. Some latex allergy sufferers may experience allergic shock [12,13,14,15,16]
