Benefits of technology

[0006] It is desirable to be able to measure the concentration of analytes in humans or other animals without having to draw a blood sample by conventional methods. It is further desirable to be able to do so with an inexpensive disposable device that is simple enough for home or hospital bedside use.

Problems solved by technology

Invasive techniques used to obtain a blood sample for analysis have the disadvantage of being painful, which can reduce patient compliance in regular monitoring.
Repeated testing, e.g., on a fingertip, can result in scar tissue build-up which makes obtaining a sample in that region more difficult.
Moreover, invasive sampling procedures pose a risk of infection or disease transmission.
However, there is no method disclosed for analyzing the drawn samples that is suitable for home use or hospital bedside use.

Abstract

The invention disclosed in this application is a method and device for combining the sampling and analyzing of sub-dermal fluid samples, e.g., interstitial fluid or whole blood, in a device suitable for hospital bedside and home use. It is applicable to any analyte that exists in a usefully representative concentration in the fluid, and is especially suited to the monitoring of glucose.

Description

RELATED APPLICATIONS [0001] This application is a continuation of U.S. application Ser. No. 10 / 369,120, filed Feb. 13, 2003, which is a continuation of U.S. application Ser. No. 10 / 166,487, filed Jun. 10, 2002, now U.S. Pat. No. 6,939,312, which is a continuation of application Ser. No. 09 / 536,235, filed Mar. 27, 2000, now U.S. Pat. No. 6,612,111.FIELD OF THE INVENTION [0002] The present invention relates to a method and device for combining the sampling and analyzing of interstitial fluid or whole blood samples which is suitable for hospital bedside and home use. BACKGROUND OF THE INVENTION [0003] The management of many medical conditions requires the measurement and monitoring of a variety of analytes in bodily fluid. Historically, the measurement of analytes in blood has required an invasive technique, such as a venipuncture or finger puncture, to obtain blood for sampling purposes. An example of an analyte which is routinely tested by obtaining a blood sample through an invasive...
