BIOLOGICAL TESTING SYSTEM |
摘要 |
<p>A connector for establishing electrical connection between a testing device (30) and a test strip (40) with a biological fluid thereon includes a contact pad (42) on the test strip (40), and one or more contact wires in the testing device. When the strip is inserted into the testing device, part of the strip' s end engages a contact portion (72) of a contact wire (60) and deflects it in a direction normal to the direction of insertion. In certain embodiments the radius of curvature (in the direction of insertion) of the contact portion is controlled to reduce abrasion of the strip by the wire. In other embodiments the radius of curvature (perpendicular to the direction of insertion) is controlled to reduce the abrasion of the strip by the wire. Sometimes the contact portion and/or contact pad is plated with a sacrificial material to reduce the coefficient of friction. In other embodiments various numbers of contacts receive the end of the strip substantially simultaneously, or are staggered in rows to distribute the resistance presented.</p> |
