Patent Images
1. A device for testing the presence of a substance in blood, comprising:
- a housing defining an inner cavity, the inner cavity configured to receive blood withdrawn from a subject;
a first chamber within the housing, the first chamber configured to receive at least some of the withdrawn blood;
a second chamber in fluid communication with the first chamber, the second chamber configured to receive at least some of the withdrawn blood from the first chamber; and
a test strip held within the second chamber,wherein a portion of the test strip that contacts the withdrawn blood including the substance in the withdrawn blood is visually distinguishable from a portion of the test strip that does not contact the withdrawn blood.

Abstract
The disclosure provides an allergy detection system for use during catheterization. The allergy detection system is incorporated into specialized syringes, connectors for use with standard syringes, or can be an independent test module designed for the sole purpose of allergy detection. The detection system features a test strip, such as an immunochromatographic test strip, and a structure to couple the system to a connector, syringe, or a housing, to form an independent test module. The detection system, by way of test strips, is used to detect potential allergic reactions.

18. A method for allergy detection during catheterization, comprising:
-
drawing blood from a subject into a first chamber within a housing of a device, the drawn blood including a substance; allowing at least some of the drawn blood from the first chamber to enter a second chamber within the housing of the device, the second chamber holding a test strip that reacts with the substance; and visually inspecting the test strip after the drawn blood in the second chamber has contacted the test strip held in the second chamber, wherein a portion of the test strip that reacts with the substance is visually distinguishable from a portion of the test strip that does not contact the drawn blood. - View Dependent Claims (20)
