TEST STRIP EJECTION MECHANISM
First Claim
1. A test strip ejection mechanism for use with a test strip receiving port and a test strip, the test strip ejection mechanism comprising:
- a framework attached to the test strip receiving port;
an elongated shape memory alloy strip with a longitudinal axis, a first end and a second end, the first end and second end constrained by attachment to the framework, the shape memory alloy strip exhibiting a solid state transition temperature;
a slider configured to travel along the framework; and
a heating module configured to heat the shape memory alloy strip from a temperature below the solid state transition temperature to a temperature above the solid state transition temperature;
wherein the shape memory alloy strip and slider are configured such that the slider travels along the framework under an applied force exerted on the slider by the shape memory alloy strip as the shape memory strip is heated by the heating module from a temperature below the solid state transition temperature to a temperature above the solid state temperature; and
wherein the slider has a proximal end configured to engage a test strip received within the test strip receiving port and eject the test strip from the test strip receiving port as the slider travels along the framework.

Abstract
A test strip ejection mechanism, for use with a test strip receiving port and a test strip, includes a framework, an elongated shape memory alloy (SMA) strip (e.g., a SMA wire), a slider, and a heating module. The SMA strip has first and second ends that are attached to the framework and exhibits a solid state transition temperature. The slider is configured to travel along the framework. The heating module is configured to heat the SMA strip from a temperature below the solid state transition temperature to a temperature above the solid state transition temperature. Moreover, the SMA strip and slider are configured such that the slider travels along the framework under an applied force exerted on the slider by the SMA strip as the shape memory strip is heated from a temperature below the solid state transition temperature to a temperature above the solid state temperature by the heating module. In addition, the slider has a proximal end configured to engage a test strip received within a test strip receiving port and eject the test strip from the test strip receiving port as the slider travels along the framework. A test meter for use with a test strip includes a test strip receiving port and a test strip ejection mechanism.
