Abstract
A simple, miniaturized, disposable acquisition and test module for monitoring glucose or other analytes successively for multiple times is described. The apparatus is designed to collect and test small volumes of blood in a single step. Many samples can be acquired and analyzed using a single disposable sampling module, minimizing the number of disposables and improving ease of use of the system.
Claims11
An apparatus for collecting blood from a patient's skin, the apparatus comprising
- a disc shaped sampling module radially partitioned into a plurality of sampling segments positioned near a periphery of the disc shaped sampling module, each sampling segment having components to perform a single blood sampling and testing event and including a sampling port, a lancet having a tip, the tip adjacent the sampling port, the lancet maintained within a housing and operable to extend the lancet tip through the sampling port to pierce the patient's skin positioned adjacent the sampling port, the disc shaped sampling module having a plurality of sample test chambers, each of a sample test chamber in fluid communication with a sampling port via a capillary channel with a diameter that is less than 0.1 mm, the sample test chambers associated with testing means, each of a sample test chamber being sized to hold no more than about 0.4 microliter of a blood sample;
- a driver configured to be coupled to the lancet, the driver being associated with a driver port;
- a first seal that seals each of a lancet tip prior to use;
- a second seal adjacent to a lancet head that seals the driver port;
- a contact interface that aligns the sampling module with a reader device;
- and
- a rotation device coupled to the sampling module and configured to rotate the sampling module into position for a new sampling event.

A method of collecting and testing a series of blood samples, the method comprising
- a) obtaining a disc shaped sampling module that is radially portioned into a plurality of sampling segments with sample test chambers, and a reader device, each sampling segment adapted to perform a single blood sampling cycle of lancing, collecting, communicating in fluid form, and testing of a blood sample, the sampling module coupled to a rotation device to rotate the sampling module into position for a new sampling event, each of a sample test chamber in fluid communication with a sampling port via a capillary channel with a diameter that is less than 0.1 mm, the sample test chambers associated with testing means, each of a sample test chamber being sized to hold no more than about 0.4 microliter of a blood sample, a driver configured to be coupled to the lancet, the driver being associated with a driver port;
- a first seal that seals each of a lancet tip prior to use a second seal adjacent to a lancet head that seals the driver port;
- a contact interface that aligns the sampling module with a reader device,
- b) coupling the sampling module to the reader device,
- c) initiating the blood sampling cycle,
- d) using the rotating device to rotate the sampling module and advancing the sampling module to bring another sampling segment online,
- e) repeating steps c) and d) until substantially all sampling segments on the sampling module have been used, and coupling the sampling module and reader device.
