Title:
DEVICE FOR SUPPLYING LIQUID TO MATRIX, AND TEST INSTRUMENT HAVING THE DEVICE
Document Type and Number:
Japanese Patent JPH10104236
Kind Code:
A
Abstract:

To prevent an expanding solution from being protruded onto a matrix and improve the reproducibility of expanding speed by breaking a covering member, making an absorber continuously present in a liquid vessel, and moving the expanding solution within a plurality of absorbers.

A matrix and a liquid housing vessel 28 are housed in a case 12, and a deformable element 16-2 is provided on the upper part of the vessel 28. As the matrix, a porous material or fiber material showing capillary action is used, and it is formed of a first absorber 21 to a fourth absorber 24. These are mutually separated, but allow a liquid to move in the contact part. When the element 16-2 is deformed, a projection 31 breaks a covering member 30 to press a part of the absorber 21 into an opening part 19, so that it is continuously in contact with an expanding solution. Since the expanding solution is then moved to the absorbers 21-24, a subject is introduced through a subject dropping window 13, and the reaction is observed through a judging window 14. Thus, the expanding solution is never protruded onto the matrix, and the reproducibility of the expanding time or expanding speed can be improved.
