Problems solved by technology

[0007] However, as described in JPA2005-69997, when the micropump is built into the body of the device, the user cannot simply replace the micropump when its lifespan ends or malfunctions.
Moreover, when replacing, air bubbles or dirt may enter the micropump, and the micropump cannot accurately transport the liquid. In the worst case, even the liquid transport itself cannot be carried out.

Embodiment Construction

[0023] Embodiments of the present invention will be described. In addition, although this invention was demonstrated based on illustrated embodiment, this invention is not limited to this embodiment. In addition, the asserted description in the embodiment of the present invention shows the best mode, and does not limit the meaning of terms and the technical scope of the present invention.

[0024] FIG. 1 is a diagram of a microchip inspection apparatus according to this embodiment. In FIG. 1 , 1 is the device body, 2 is the pump module, and the microchip 3 can be disassembled from the microchip insertion port 4 of the device body 1 in the direction of arrow A. Moreover, the pump module 2 is mounted on the inner upper part of the device body as viewed from the side having the insertion port of the microchip, and the device body 1 and the pump module 2 are connected in a liquid-tight manner through the connection part C1. In addition, the device main body 1 has a power supply ...

Abstract

The present invention provides a microchip inspection apparatus, capable of easily being maintenance and forming a flowing system structure which bubble or dust ect can not enter. Since forming pump module is detachable structure relative to the device body, users can easily change micropump and supply driving liquid by changing pump module, and the device is not damaged. Futhermore, bubble and dust can not enter the micropump in the changing course, the condition that the micropump can not accurately transport liquid or can not proceed liquid transportation, is not happen.

Description

technical field [0001] The present invention relates to a microchip inspection device. Background technique [0002] In recent years, attention has been paid to a system that utilizes micromechanical technology and ultramicromachining technology to integrate existing devices and mechanisms (such as pumps, valves, fluids, etc.) for sample preparation, chemical analysis, and chemical synthesis. circuits, sensors, etc.) and integrated on a single chip. This is called μ-TAS (Micro Total Analysis System), and it uses reagents and samples (for example, after processing urine, saliva, blood of the subject being tested) on a part called a microchip. A method in which the extracted DNA-treated extraction solutions, etc.) are merged, and the characteristics of the sample are studied by detecting the reaction. [0003] In microchips, groove processing is performed on a substrate formed of resin material or glass material by photolithography (photolithography) (a method of etching a p...
