Abstract
A dry chemical analysis element cartridge includes a box-like cartridge casing in which a plurality of chemical analysis elements are stacked and are taken out through an element take-out port formed at one end of the cartridge casing. The inner dimension of the cartridge casing in the direction of the stack of the chemical analysis elements is smaller than the longitudinal and transverse dimensions of each of the chemical analysis elements.
Claims12
A dry chemical analysis element cartridge comprising:
- a box-shaped cartridge casing without a pressing member or urging member for preventing the flat chemical analysis element from being turned over, the cartridge casing comprising:
- an upper inner surface of the cartridge casing being disposed in a parallel relationship to a lower inner surface of the cartridge casing;
- and
- a first end inner surface of the cartridge casing and a second end inner surface of the cartridge casing being disposed in a perpendicular relationship to the upper inner surface of the cartridge casing and cooperating with the upper inner surface of the cartridge casing and the lower inner surface of the cartridge casing to form an element holding chamber for holding a plurality of flat chemical analysis elements in a planar position that is parallel to the upper inner surface of the cartridge casing;
- wherein the plurality of flat chemical analysis elements are stacked in a stack and are taken out one by one through an element take-out port formed at at least one of the first end inner surface of the cartridge casing and the second end inner surface of the cartridge casing, and
- wherein an inner dimension of the cartridge casing in a direction of the stack of the chemical analysis elements is smaller than a longitudinal dimension and a transverse dimension of each of the chemical analysis elements for preventing the chemical analysis element from being turned over.

A dry chemical analysis element cartridge comprising:
- a box-shaped cartridge casing in which a plurality of flat chemical analysis elements are stacked in a stack and are taken out one by one through an element take-out port formed at a side wall of the cartridge casing;
- wherein an inner dimension of the cartridge casing in a direction of the stack of the chemical analysis elements is smaller than a longitudinal and transverse dimension of each of the chemical analysis elements, thereby preventing each of the chemical analysis elements from being turned over inside the cartridge casing and maintaining the chemical analysis elements in a stacked state without using a pressing member or an urging member to press or urge the chemical analysis elements toward an end of the cartridge casing;
- wherein the inner dimension of the cartridge casing has a fixed dimension between an inner surface of a top end face of the cartridge casing and an inner surface of a bottom end face of the cartridge casing;
- wherein the inner surface of the top end face of the cartridge casing is parallel to the inner surface of the bottom end face of the cartridge casing;
- and
- wherein the inner surface of the top end face of the cartridge casing is perpendicular to the side wall of the cartridge casing.
