Apparatus for measuring blood cell deformability

Abstract

A disposable blood test kit inserted into an instrument for measuring the blood cell deformability is provided to avoid a washing process during a blood test. The instrument comprises a disposable blood test kit ( 20 ) for directly containing the blood sample, a light emitting unit ( 10 ) disposed above the disposable blood test kit ( 20 ), and a measurement unit ( 30 ) for measuring the blood cell deformability. The disposable blood test kit ( 20 ) comprises a tiny blood sample pot ( 21 ) for containing the blood sample, a slit channel ( 22 ) made of a transparent material, and a tiny waste blood pot ( 23 ) for collecting the tested blood sample. A differential pressure is applied to the disposable blood test kit ( 20 ) to make the stagnant blood sample flow through the slit channel ( 22) and to collect the tested blood sample at the tiny waste blood pot ( 23 ).

Description

technical field [0001] The invention relates to a device for measuring the degree of deformation of blood cells. More specifically, a disposable blood test kit is provided to avoid cleaning procedures in blood tests. Background technique [0002] Since it has now been found that the degree of deformation of blood cells directly affects the viscosity and various characteristics of blood cells, research on the development of devices for measuring the degree of deformation of blood cells has become a hot topic. [0003] In particular, a journal called "Clinical Hemorheology and Microcirculation" (Vol.14, pp.605-618, 1994) introduced a system formed as a rotary Couette flow Laser-Assisted Optical Rotary Cell Analyzer (LORCA) for measuring blood cell deformation. The device emits laser beams to blood cells during rotation, and captures diffraction images through a CCD camera to analyze and measure blood cell deformation through computer programming. [0004] Since the shear fo...

Problems solved by technology

[0007] This conventional device also has the drawback that it takes one to two hours to analyze the captured image of the blood sample, and the surfaces of the device that come into contact with the blood sample must be cleaned after the experiment

[0008] On the other hand, a common problem with conventional devices is that the device surfaces that come into contact with the blood sample must be cleaned after each experiment

Therefore, it is inconvenient and burdensome to maintain clean equipment after washing

[0009] Moreover, special training is required to operate these traditional devices, and professional supervision is required to analyze blood samples

Therefore, these conventional devices are not suitable for practical use in clinical settings
