Abstract

Test strip holders for use with test strip meters are provided. The subject test strip holders include at least an opening and a lip associated with the opening. The lip element of the subject holders is capable of forming a liquid seal with the upper surface of a test strip upon insertion of the test strip into the opening. In many embodiments, the strip holder is configured to at least partially encompass a sample application region of a test strip upon insertion of the strip into the opening. Also provided are meters on which the subject test holders are present, as well as methods for using the same.

Claims

1. A strip holder for use with a meter, said strip holder comprising:

a support for receiving a test strip;

a lip associated with said support, said lip and said support defining an opening therebetween, wherein said lip forms a liquid seal with the upper surface of said test strip and is configured to at least partially encompass a sample application region of said test strip when said test strip is inserted into said opening; and

a raised bump on said support that contacts the bottom surface of said test strip when inserted into said opening, wherein the force applied by said lip on said top surface of said test strip inserted into said opening is substantially equal and opposite in direction as the force applied by said raised bump on said bottom surface of said test strip inserted into said opening.

2. The strip holder according to claim 1, wherein said lip forms a semi-circle around said sample application region of said test strip.

3. The strip holder according to claim 1, wherein said applied forces range in magnitude from about 0.01 lb to 0.05 lb.

4. A test strip meter system comprising:

a test strip meter having a measurement system and an entrance for receiving a test strip;

a test strip holder, wherein said test strip holder comprises;

a support for receiving a test strip;

a lip associated with said support, said lip and said support defining an opening therebetween, wherein said lip forms a liquid seal with the upper surface of said test strip and is configured to at least partially encompass a sample application region of said test strip when said test strip is inserted into said opening; and

a raised bump on said support that contacts the bottom surface of said test strip when inserted into said opening, wherein the force applied by said lip on said top surface of said test strip inserted into said opening is substantially equal and opposite in direction as the force applied by said raised bump on said bottom surface of said test strip inserted into said opening.

5. The system according to claim 4, wherein said strip holder is readily removable from said meter.

6. The system according to claim 4, wherein said system further comprises said test strip inserted into said opening of said strip holder.

7. A method of using a test strip meter system said method comprising:

providing a test strip meter having a measurement system and an entrance for receiving a test strip;

(a) providing, wherein said test strip holder comprises;

(i) a support for receiving a test strip;

(ii) a lip associated with said opening, wherein said lip forms a liquid seal with the upper surface of said test strip and is configured to at least partially encompass a sample application region of said test strip when said test strip is inserted into said opening; and

(iii) a raised bump on said support that contacts the bottom surface of said test strip when inserted into said opening, wherein the force applied by said lip on said top surface of said test strip inserted into said opening is substantially equal and opposite in direction as the force applied by said raised bump on said bottom surface of said test strip inserted into said opening; and

(b) inserting said test strip into said opening and into said meter.
