1. A connector for indicating the presence of a substance in blood, the connector comprising:
- a housing having;
a proximal end defining a proximal opening and a first channel, the proximal end having Luer threads configured to removably couple with a distal end of a medical device, and the first channel being in fluid communication with the medical device through the proximal opening when the proximal end is coupled to the medical device;
a distal end defining a distal opening and a second channel, the distal end having a coupling configured to removably couple with a hub of a needle, the second channel being in fluid communication with the needle through the distal opening when the distal end is coupled to the hub of the needle, anda window defining a hollow interior for receiving withdrawn blood from the second channel that is received from the needle, the window being between the proximal and distal ends of the housing; and
a test strip held within the hollow interior of the housing, the test strip being configured to produce a signal visible through the window that indicates the presence or absence of the substance in the withdrawn blood.

Abstract
A coupler for indicating the presence of a substance in blood is disclosed. The coupler includes a housing and a test strip. The housing has a proximal end and a distal end, and defines a hollow interior for receiving withdrawn blood. The test strip is held within the hollow interior of the housing. The housing removably couples with a medical instrument and a needle. The test strip produces a visible signal that indicates the presence or absence of the substance in the withdrawn blood. A kit including a syringe, a needle and the coupler is also disclosed.

11. A kit, comprising:
-
a syringe comprising a plunger, the syringe having a distal end; a needle comprising a needle hub at its proximal end and a sharp tip at its distal end; and a connector for indicating the presence of a substance in blood, the connector comprising; a housing having; a proximal end defining a proximal opening and a first channel, the proximal end of the housing having Luer threads configured to removably couple with the distal end of the syringe, and the first channel being in fluid communication with the syringe through the proximal opening when the proximal end of the housing is coupled to the syringe; a distal end defining a distal opening and a second channel, the distal end of the housing having a coupling configured to removably couple with the needle, the second channel being in fluid communication through the distal opening with the needle when the distal end is coupled to the needle hub, and a window defining a hollow interior for receiving withdrawn blood from the second channel that is received from the needle, the window being between the proximal and distal ends of the housing; and a test strip held within the hollow interior of the housing, the test strip being configured to produce a signal visible through the window that indicates the presence or absence of the substance in the withdrawn blood. - View Dependent Claims (12, 13, 14, 15)
