Abstract

In some aspects, a modular analyte measurement system having a replaceable strip port module is provided to permit contaminated modules to be replaced. Some aspects of the present disclosure related to barriers for strip ports or the sealing of strip ports and/or analyte measurement devices to maintain a clean strip port and/or enable the strip port to be cleaned for reuse. Cleaning tools are also provided. Also provided are strip port interfaces that guide fluid away from the strip port opening, as well as absorptive elements that prevent fluid from entering a strip port. Analyte measurement devices with gravity sensors or accelerometers are also provided, along with methods related thereto. Also provided are docking station that serve as an information server and provides storage and recharging capabilities.

Claims

1. A method for determining the concentration of analyte in a sample using an analyte measurement system, the method comprising:

positioning a replaceable strip port module within a strip port cavity of a housing of an analyte meter, wherein the analyte meter comprises the housing and electrical connections disposed with the strip port cavity within the housing, and the replaceable strip port module comprises;

a module housing comprising an electrical interface aperture that exposes an electrical interface within the module housing, and

an analyte test strip port disposed within the module housing and comprising electrical contacts that couple to an analyte test strip positioned in the analyte test strip port,

wherein the electrical interface is disposed within the module housing and coupled to the analyte test strip port, and wherein the electrical interface comprises a plurality of electrical contacts that couple to electrical contacts of the analyte meter through the electrical interface aperture of the module housing;

contacting the sample to the analyte test strip positioned in the analyte test strip port of the replaceable strip port module;

electrochemically determining the concentration of the analyte in the blood sample using the analyte meter.

2. The method according to claim 1, wherein the concentration of glucose is determined.

3. The method according to claim 1, wherein the sample is a blood sample.

4. The method according to claim 1, wherein the module housing fits within an aperture in the housing of the analyte meter.

5. The method according to claim 4, wherein the module housing comprises external alignment features to align the module housing within the aperture in the housing of the analyte meter.

6. The method according to claim 4, wherein the housing of the analyte meter comprises alignment features to align the module housing within the aperture in the meter housing.

7. The method according to claim 1, wherein the module housing comprises a first aperture that receives an analyte test strip.

8. The method according to claim 1, wherein the analyte test strip port is disposed within the module housing.

9. The method according to claim 1, wherein the electrical interface electrically couples to the analyte meter through the interface aperture of the module housing.

10. The method according to claim 8, wherein the analyte test strip port comprises electrical contacts that couple to an analyte test strip positioned in the first aperture of the module housing.

11. The method according to claim 1, wherein the electrical contacts of the electrical interface electrically couple to the analyte test strip port and the analyte meter.

12. The method according to claim 1, wherein positioning a replaceable strip port module in the housing of the analyte meter comprises electrically coupling the replaceable strip port module to electrical connections within the housing of the analyte meter.

13. The method according to claim 1, wherein positioning a replaceable strip port module in the housing of the analyte meter comprises:

inserting the replaceable strip port module into the housing of the analyte meter, and

attaching the replaceable strip port module to the analyte meter by inserting an attachment feature in the housing of the analyte meter and the replaceable strip port module.

14. The method according to claim 13, wherein inserting the replaceable strip port module into the meter aligns the opening in the housing of the analyte meter with an opening in the replaceable strip port module, and

attaching the replaceable strip port module to the analyte meter further comprises inserting the attachment feature into the opening in the replaceable strip port module.

15. The method according to claim 13, wherein inserting the attachment feature in the housing of the analyte meter and the replaceable strip port module comprises:

aligning an attachment aperture in the housing of the analyte meter with an attachment aperture in the replaceable strip port module, and

positioning the attachment feature within the attachment aperture of the housing of the analyte meter and the attachment aperture of the second replaceable strip port.

16. The method according to claim 1, wherein the interface aperture is on a top side of the module housing, and

the module housing further comprises an opening for receiving an attachment feature on a bottom side of the module housing, wherein the bottom side of the module housing is opposite from the top side.

17. The method according to claim 1, wherein the housing of the analyte meter comprises an outer surface and the replaceable strip port module comprises a cap having an outer surface, and

wherein positioning the replaceable strip port module in the analyte meter housing comprises aligning the outer surface of the analyte meter housing with the outer surface of the cap so that the outer surfaces are flush.
