Problems solved by technology

[0004] However, in the field of drug discovery / medical / biotech, which is susceptible to metal ions, the wetted part must be metal-free
In addition, when the chemical solution / reagent is replaced, if the previously used chemical solution / reagent is mixed with a new chemical solution / reagent, not only the performance will be reduced, but also an unexpected effect will be caused due to the interaction, so it must be avoided.
[0005] However, the interior of a typical liquid ejection head is made of metal material, and is composed of narrow fluid flow paths and spaces.
Therefore, the inside of the liquid ejection head cannot be thoroughly cleaned, and therefore, a liquid ejection head capable of easily replacing the liquid contact portion has been proposed (Patent Document 1)

Embodiment approach 1

[0035]

[0036] Figure 1A It is a schematic diagram showing the internal structure of the liquid ejection device according to Embodiment 1 of the present invention viewed obliquely from above. In the liquid ejection device 100 , the base body 101 has a driving portion 110 and a fixing portion 120 . The driving unit 110 is a part having a driving mechanism for pressurizing the nozzle 150 . The fixing part 120 is a part having a mechanism for fixing the nozzle 150 .

[0037] A piezoelectric element 111 that generates displacement is provided in the drive unit 110 . In synchronization with the drive pulse signal generated by the external waveform generator 130 , the piezoelectric element 111 is displaced telescopically. In the following, the piezoelectric element 111 will be used for description, but any mechanism other than the piezoelectric element 111 may be used as long as it is a mechanism that generates displacement.

[0038] in addition, Figure 1B It is a schematic...

Embodiment approach 2

[0069]

[0070] Figure 5 It is a schematic diagram showing the cross-sectional structure of the liquid ejection device 200 in Embodiment 2 viewed from the side. Items not described are the same as those in Embodiment 1. The difference from Embodiment 1 is that the nozzle is pressurized and compressed from both sides.

[0071] The liquid ejection device 200 is equipped with a pair of driving parts 210 inside the base body 201 .

[0072] A piezoelectric element 211 that generates displacement is provided in the driving unit 210 . The piezoelectric element 211 expands and contracts in synchronization with the drive pulse signal generated by the external waveform generator 230 to generate displacement.

[0073] In addition, the drive unit 210 is fixed at the end of the base body 201 . In addition, the position of the drive unit 210 is held by the fixed rod 202 . The drive unit 210 inserted into the fixed rod 202 is processed to have an oblong shape whose major axis is the ...

Embodiment approach 3

[0085] Embodiment 3 is an application example of the liquid ejection devices 100 and 200 described above and the liquid ejection devices 700 and 900 described below. These devices are capable of applying a small amount of liquid with high precision and a constant amount over a long period of time.

[0086] Therefore, it can be used to apply blood to biosensors, biochips, and the like. For example, when applying blood to a blood sensor, the liquid ejection device 100, 200, 700, or 900 applies liquid droplets to the blood sensor, and the blood sensor is read by a detector to know the amount of blood. value. In this method, the accuracy of the volume of blood is good, and the result is correct.

[0087] Instead of a blood sensor, coating may be applied to an immunosensor for a tumor marker, a cardiac disease marker, or the like. Furthermore, the sensor may be a DNA sensor for epigenetics, infectious diseases, or the like. As sensors, biosensors can be widely used.

Description

technical field [0001] The present invention relates to a liquid discharge device for liquid discharge, a sensor device having the liquid discharge device, and a cell culture device provided with the liquid discharge device. In particular, it relates to a liquid ejection device suitable for the supply and dispensing of liquid medicines / reagents, etc. in the fields of drug discovery / medicine / biotechnology, a sensor manufacturing device having the liquid ejection device, and a liquid ejection device having the liquid ejection device. Device for cell culture devices. Background technique [0002] In recent years, inkjet-based printing devices have become popular and widely known as devices for recording characters and images on various recording media. The inkjet is not only applied to printing on paper and film, but also gradually applied to the fields of drug discovery / medical / biotechnology. The scope of application of inkjet has been greatly expanded. [0003] In particul...
