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 relate 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 is a docking station that serves as an information server and provides storage and recharging capabilities.

Claims

1. A glucose measurement system, comprising:

a glucose meter having a meter housing and a processing circuit disposed within the housing; and

a replaceable strip port module having;

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

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

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

2. The glucose measurement system of claim 1, further comprising an attachment feature to removably attach the replaceable strip port module to the glucose meter.

3. The glucose measurement system of claim 1, wherein the module housing fits within an aperture in the meter housing.

4. The glucose measurement system of claim 1, wherein the module housing fits wholly within a cavity of the meter housing.

5. The glucose measurement system of claim 3, wherein the module housing includes external alignment features to align the module housing within the aperture in the meter housing.

6. The glucose measurement system of claim 3, wherein the meter housing includes alignment features to align the module housing within the aperture in the meter housing.

7. The glucose measurement system of claim 1, wherein the electrical interface includes a plurality of pins to couple to a pin header within the meter housing.

8. The glucose measurement system of claim 1, wherein the electrical interface includes an edge connector to couple to a corresponding edge connector within the meter housing.

9. The glucose measurement system of claim 1, wherein an outer surface of the module housing of the replaceable strip port module is flush with an outer surface of the meter housing.

10. The glucose measurement system of claim 1, wherein the glucose meter further comprises a barcode reader.

11. The glucose measurement system of claim 1, wherein the glucose meter comprises an antimicrobial coating over an outer surface of the meter housing.

12. The glucose measurement system of claim 1, wherein the glucose meter comprises a wireless communication module.

13. The glucose measurement system of claim 1, wherein the wireless communication module is a WiFi module.

14. The glucose measurement system of claim 1, wherein the replaceable strip port is internally sealed to contain fluid within the replaceable strip port and prevent liquid intrusion from the replaceable strip port into the glucose meter.

15. The glucose measurement system of claim 1, wherein a cap gasket is provided as a seal between the module housing of the replaceable strip port and the meter housing of the glucose meter.

16. The glucose measurement system of claim 1, wherein a second cap gasket is provided as a seal between the module housing of the replaceable strip port and the meter housing of the glucose meter.

17. The glucose measurement system of claim 1, wherein the glucose meter further comprises a display coupled to the processing circuit disposed within the housing.

18. The glucose measurement system of claim 1, wherein the display is a touchscreen display or a liquid crystal display (LCD).

19. The glucose measurement system of claim 1, wherein the strip port is configured for use with a glucose test strip and a ketone test strip to determine concentrations of glucose and ketone bodies in body fluid sample.
