Abstract
Diagnostic devices for detecting the presence of an analyte in a sample are provided. Devices of the present invention comprise a means for inducing a pressure differential on a sample to direct the sample to a test surface. In one embodiment, the means for inducing a pressure differential on a sample to direct the sample to a test surface comprises a syringe that can be used to draw a sample from an opening to a test surface. In other embodiments, the device also provides means for diluting a sample. In yet other embodiments, the device also provides a means
Claims34
A diagnostic device comprising a test surface and a means for inducing a pressure differential on a sample to direct the sample to a test surface and then clear the sample or a significant portion of the sample from the test surface so that the test surface can be analyzed.
A disposable diagnostic device comprising
- an opening for receiving a sample,
- a test surface printed with a binder for detecting an analyte and in fluid communication with the opening for receiving a sample, and
- a means for inducing a pressure differential on the sample to direct the sample from the opening for receiving a sample to the test surface and then clear the sample or a significant portion of the sample from the test surface so that the test surface can be analyzed.
A disposable diagnostic device comprising:
- a housing, the housing comprising an opening for receiving a sample, a recess, and a channel connecting the opening to the recess,
- a test strip removably attached to the housing and in fluid communication with the recess and a binder printed in a defined pattern on a surface of the test strip, wherein the test strip and the recess form a chamber over the binder,
- and a means for inducing a pressure differential on a sample to direct the sample to the test surface.
