Reaction chamber unit for test strips

Claim 2

A REACTION CHAMBER UNIT FOR TEST STRIPS, COMPRISING A SLIDE TRAY WHICH IS OPEN AT THE TOP AND AT ONE END, AND HAS A PLANAR LOWER SURFACE FOR RECEIVING THE TEST STRIP, A HOUSING FOR SAID TRAY FORMED OF A CLEAR PLASTIC WHICH IS OPEN AT THE BOTTOM AND AT ONE END FOR RECEIVING SAID TRAY, THE INNER UPPER SURFACE OF SAID HOUSING BEING PLANAR, PARALLEL TO SAID PLANAR LOWER SURFACE OF SAID TRAY, SAID PLANAR SURFACES HAVING A PRECISE, PREDETERMINED DISTANCE OF SEPARATION OF ABOUT 2-10 MM. WHEN SAID TRAY IS PROPERLY POSITIONED IN SAID HOUSING,. AND GUIDE MEANS FOR GUIDING SAID TRAY INTO A PRECISE FIT IN SAID HOUSING, SAID GUIDE MEANS COMPRISING A PAIR OF DIAGONALLY EXTENDING SHOULDERS ON THE OUTSIDE SURFACE OF THE SIDE WALLS OF SAID TRAY AND A PAIR OF COOPERATIVELY ENGAGING CORRESPONDING DIAGONAL SHOULDERS ON THE INSIDE FACE OF THE SIDE WALLS OF SAID HOUSING, WHEREBY SAID PLANAR SURFACES ARE AUTOMATICALLY DRAWN INTO PRECISE SPATIAL RELATIONSHIP BY THE ENTRY IF SAID TRAY INTO SAID HOUSING.

Claim 3

A reaction chamber unit according to claim 1, wherein said slide tray is open at the same end as said housing.

Claim 4

A reaction chamber unit according to claim 1, wherein said slide tray extends beyond said housing when fully inserted therein for facilitating the gripping of the tray.

Claim 5

A reaction chamber unit according to claim 1, wherein said housing has a plurality of downward projecting sides joined to a common top forming, when a corresponding number of trays are inserted therein, a plurality of parallel positioned reaction chamber units.

Claim 6

A reaction chamber unit for test strips, comprising a slide tray which is open at the top and at one end, and has a planar lower surface for receiving the test strip, a housing for said tray formed of a clear plastic which is open at the bottom and at one end for receiving said tray, the inner upper surface of said housing being planar, parallel to said planar lower surface of said tray, said planar surfaces having a precise, predetermined distance of separation when said tray is properly positioned in said housing, and guide means for guiding said tray into a precise fit in said housing, said guide means comprising a pair of diagonally extending shoulders on the outside surface of the side walls of said tray and a pair of cooperatively engaging corresponding diagonal shoulders on the inside face of the side walls of said housing, whereby said planar surfaces are automatically drawn into precise spatial relationship by the entry of said tray into said housing, said slide tray being open at the same end as said housing, and wherein said slide tray has a portion extending beyond said housing when fully inserted therein, and said extending portion is serrated for facilitating the gripping of the tray.

Claim 7

A reaction chamber unit for test strips, comprising a slide tray which is open at the top and at one end, and has a planar lower surface for receiving the test strip, a housing for said tray formed of a clear plastic which is open at the bottom and at one end for receiving said tray, the inner upper surface of said housing being planar, parallel to said planar lower surface of said tray, said planar surfaces having a precise, predetermined distance of separation when said tray is properly positioned in said housing, and guide means for guiding said tray into a precise fit in said housing, said guide means comprising a pair of diagonally extending shoulders on the outside surface of the side walls of said tray and a pair of cooperatively engaging corresponding diagonal shoulders on the inside face of the side walls of said housing, whereby said planar surfaces are automatically drawn into precise spatial relationship by the entry of said tray into said housing, said slide tray being open at the same end as said housing, and wherein said slide tray has a portion extending beyond said housing when fully inserted therein, and said extending portion is serrated for facilitating the gripping of the tray.

Claim 8

A reaction chamber unit for test strips, comprising a slide tray which is open at the top and at one end, and has a planar lower surface for receiving the test strip, a housing for said tray formed of a clear plastic which is open at the bottom and at one end for receiving said tray, the inner upper surface of said housing being planar, parallel to said planar lower surface of said tray, said planar surfaces having a precise, predetermined distance of separation when said tray is properly positioned in said housing, and guide means for guiding said tray into a precise fit in said housing, said guide means comprising a pair of diagonally extending shoulders on the outside surface of the side walls of said tray and a pair of cooperatively engaging corresponding diagonal shoulders on the inside faces of the side walls of said housing, whereby said planar surfaces are automatically drawn into precise spatial relationship by the entry of said tray into said housing and wherein said housing has a plurality of downward projecting sides joined to a common top forming, when corresponding trays are inserted therein, a plurality of parallel positioned reaction chamber units, and wherein each of said slide trays is open at the same end as said housing, and wherein said slide trays have portions extending beyond said housing when fully inserted therein, and said extending portions are serrated for facilitating the gripping of the trays.

Claim 9

A reaction chamber unit for test strips, comprising a slide tray which is open at the top and at one end, and has a planar lower surface for receiving the test strip, a housing for said tray formed of a clear plastic which is open at the bottom and at one end for receiving said tray, the inner upper surface of said housing being planar, parallel to said planar lower surface of said tray, said planar surfaces having a precise, predetermined distance of separation when said tray is properly positioned in said housing, and guide means for guiding said tray into a precise fit in said housing, said guide means comprising a pair of diagonally extending shoulders on the outside surface of the side walls of said tray and a pair of cooperatively engaging corresponding diagonal shoulders on the inside faces of the side walls of said housing, whereby said planar surfaces are automatically drawn into precise spatial relationship by the entry of said tray into said housing and wherein said housing has a plurality of downward projecting sides joined to a common top forming, when corresponding trays are inserted therein, a plurality of parallel positioned reaction chamber units, and wherein each of said slide trays is open at the same end as said housing, and wherein said slide trays have portions extending beyond said housing when fully inserted therein, and said extending portions are serrated for facilitating the gripping of the trays.
