Embodiment Construction

[0095] Figure 1 ~ Figure 4 It is a figure which shows the apparatus structure of the clinical examination apparatus of this invention.

[0096] figure 1 is the external view of the clinical examination device, figure 1 (A) indicates the state with the lid closed, figure 1 (B) shows the state in which the chip insertion port of the clinical examination device can be seen by opening the cover.

[0097] Such as figure 1 As shown in (A), the clinical examination device 1 includes a housing 1A. When inserting the microchip into the clinical examination device, if figure 1 As shown in (B), open the cover 1B of the casing 1A, and put the microchip into the measurement chamber through the chip insertion port 1C of the casing 1A (see figure 2 )Inside.

[0098] Figure 2 ~ Figure 4 is the configuration in the figure 1 The figure of the structure of the measuring part 20 inside the housing 1A shown. figure 2 is a perspective view showing the measuring unit 20, image ...

Abstract

The present invention relates to a clinical laboratory test apparatus capable of simply and quickly attaching and detaching a microchip. The clinical laboratory testing apparatus comprises a microchip having a measuring cell that holds a sample liquid; a rotation body; a rotation drive mechanism that rotates the rotation body; a lock mechanism that locks the microchip on the rotation body; a measurement room that holds the microchip and the rotation body and that has an attachment and detachment opening; a protection cover that closes the attachment and detachment opening; a light source that irradiates the measuring cell; and a light receiving unit that receives the light, wherein a centrifugal separation processing of a specimen in the sample liquid is performed in the microchip by the rotation drive mechanism rotating the rotation body, and wherein the protection cover has a pressing-down member that presses down a wall face of the microchip when the protection cover is closing the attachment and detachment opening.

Description

technical field [0001] The present invention relates to a clinical examination device for centrifuging a microchip holding a sample such as blood to measure the concentration of a detection target component contained in a test solution held by the microchip. Background technique [0002] In recent years, the use of micro-device technology, which can perform chemical analysis in a smaller size than conventional devices, uses the so-called "μ-TAS (μ-Total Analysis System: micro-total analysis system)" or "Lab on a chip (lab-on-a-chip)" microchip analysis method has attracted much attention. [0003] The purpose of an analysis system using such a microchip (hereinafter referred to as a microchip analysis system) is to realize the mixing, reaction, and separation of reagents in a fine flow path formed on a small base using microdevice fabrication technology. All processes of analysis including extraction and detection, for example, in the analysis of blood in the medical field,...
