Heated reaction chamber in a unified fluid circuit of a hematology diagnostic instrument
First Claim
1. In a unified fluid circuit having a first acrylic layer and a second acrylic layer having a common interface there between, an integral heated reaction chamber comprising:
- a hollow surface formed in one of the first and second acrylic layers at the common interface to form a chamber containing a volume;
a thinning notch formed in at least one of the first and second layers proximate to the chamber, defining a thin wall of said chamber bounded on a first side by said chamber and on a second side by the thinning notch; and
a heating element in thermal contact with said second side of said thin wall.

Abstract
An integral heated reaction chamber for use in a unified fluid circuit having an acrylic body. The acrylic body is preferably formed of first and second acrylic layers bonded or fused together. A chamber half is formed in each of the acrylic layers and the layers are bonded together in opposition. A thinning notch is provided in one of the acrylic layers to form a thin wall of the chamber, and a heater element is secured adjacent the thin wall to heat the contents of the chamber. A temperature sensor is provided to monitor the temperature of the chamber contents. The sensed temperature may be used to control the heating element and the heating time according to a predetermined reaction protocol.

17. In a unified fluid circuit, an integral reaction chamber comprising:
-
an acrylic body; a cavity formed in the acrylic body, the cavity defining a reaction chamber; a thinning notch formed in the acrylic body proximate to said cavity and defining a thin wall of said reaction chamber bounded on a first side by the cavity and on a second side by the thinning notch; and a heating element in thermal contact with said second side of said thin wall. - View Dependent Claims (18, 19, 20, 21, 22)
