Diagnostic test strip having fluid transport features
First Claim
1. A test strip for testing a fluid sample, comprising:
- a strip with a first major side for positioning facing a the fluid sample;
a capillary channel having a mouth and having a measurement site;
a raised fluid transport path on the strip terminating at the mouth of the capillary channel;
a raised depending portion that is integral to the raised fluid transport path and positioned at an end of the raised fluid transport path opposite the mouth of the capillary channel, whereby a droplet of the fluid sample contacting the raised depending portion is directed to the raised fluid transport path; and
a lancet hole through the strip that is positioned laterally adjacent to the raised depending portion.

Abstract
A test strip for testing a blood sample is provided with a fluid transport feature to facilitate transport of a blood sample obtained from a lancing operation through a capillary channel to a measurement site. A fluid transport path is defined on the major face of the strip terminating at the mouth of the capillary channel. The fluid transport path includes a depending portion at one end opposite the mouth of the channel. The depending portion extends away from the strip on the side facing the fluid sample, such that a droplet of fluid sample contacting the depending portion is directed toward the mouth of the capillary channel. Thereafter the sample moves by capillary action to the measurement site.

-
a strip with a first major side for positioning the fluid sample; a capillary channel having a mouth and having a measurement site; a raised fluid transport path on the strip having sides and an end at the mouth of the capillary channel; at least one recess adjacent a side of the raised fluid transport path, whereby the fluid sample contacting the raised fluid transport path is preferentially directed to the mouth of the capillary channel; and a lancet hole through the strip that is positioned adjacent to a raised depending portion, the raised depending portion being integral to the raised fluid transport path and positioned at an end of the raised fluid transport path opposite the mouth of the capillary channel. - View Dependent Claims (16)
