Abstract: A blood coagulation testing apparatus for determining compatibility between donor's blood and patient's blood before blood transfusion. The blood coagulation testing apparatus includes: a cylindrical main body connected at one end thereof to a supply tube for delivering donor's blood and connected at the other end thereof to a blood transfer tube for introduction of patient's blood, wherein the main body is divided into two sections by a barrier film extending in a longitudinal direction of the main body such that blood is introduced into the main body through two paths, wherein the donor's blood and the patient's blood are introduced into one of the two sections through one end of the main body and the other end of the main body, respectively, and wherein the barrier film is formed on a surface thereof with a blood coagulation indicator for checking coagulation.

Abstract: Disclosed herein are a method of manufacturing multiple microelectrodes on a syringe needle and a syringe needle manufactured by the same. The syringe needle includes multiple interdigitated electrodes (IDEs) placed on a surface of a portion of the syringe needle spaced apart from a tip of the syringe needle, a pair of interconnection lines for electrical connection of the multiple IDEs, the interconnection lines electrically connecting a first group of the IDEs on the left and a second group of the IDEs on the right through one end of each of the interconnection lines, and a conductor for electrical connection to a PCB provided to a main body of a syringe at the other end of each of the interconnection lines, wherein the multiple IDEs are basically formed of a material for a dielectric layer and are alternately arranged at a first distance from one another.
