Abstract

An analyte meter to detect an analyte concentration level in a bio-fluid sample may be cleaned and disinfected with a cleaning liquid without harming electrical and internal meter components. In some embodiments, the analyte meter is washable and immersable and may include a sealed sensor connector, sealed battery connector, and possibly a sealed USB connector that may be subjected to a cleaning liquid without the liquid entering an internal chamber of the analyte meter and contacting internal electronic components. In some embodiments, a sealed display screen and sealed keypad are provided such that liquids are prevented from entering the internal chamber. Manufacturing methods and systems utilizing the analyte sensors are provided, as are numerous other aspects.

Claims

1. An analyte meter, comprising:

a meter housing having an internal chamber that is liquid impermeable, the meter housing having a recessed pocket;

electronic components for carrying out analyte measurements, the electronic components residing within the internal chamber; and

an analyte sensor electrical connector unit received in the recessed pocket, the analyte sensor electrical connector unit having a port entryway, a sensor port configured to receive an analyte sensor through the port entryway, at least two electrodes disposed in the sensor port coupled to the electronic components via a sealed connection, and at least one wash port separate from the port entryway;

wherein;

a fluid flow channel is formed between the at least one wash port and the port entryway such that application of a liquid onto the at least two electrodes does not adversely affect the analyte meter.

2. The analyte meter of claim 1, further comprising a display screen sealed to the meter housing to prevent fluids from entering the internal chamber.

3. The analyte meter of claim 1, further comprising a keypad sealed to the meter housing to prevent fluids from entering the internal chamber.

4. The analyte meter of claim 1, further comprising a battery connector sealed to the meter housing to prevent fluids from entering the internal chamber.

5. The analyte meter of claim 1, further comprising a universal serial bus (USB) port sealed to the meter housing to prevent fluids from entering the internal chamber.

6. The analyte meter of claim 1, wherein the electronic components comprise a processor and a memory.

7. The analyte meter of claim 1, further comprising at least two electrical connectors coupled respectively to the at least two electrodes via the sealed connection such that an end of each of the at least two electrical connectors extends beyond a connector body of the analyte sensor electrical connector unit.

8. The analyte meter of claim 1, wherein the meter housing comprises a first part and a second part interfacing with and sealed to one another to form the internal chamber.

9. The analyte meter of claim 1, wherein the at least one wash port comprises a plurality of elongated slots.

10. An analyte meter, comprising:

a meter housing having an internal chamber that is liquid impermeable;

electronic components for carrying out analyte measurements, the electronic components residing within the internal chamber; and

a replaceable battery cartridge having a battery connector coupled to the electronic components, the battery connector sealed to protect against liquid ingress into the internal chamber.

11. The analyte meter of claim 10, further comprising an analyte sensor electrical connector unit received in a recessed pocket of the meter housing, the analyte sensor electrical connector unit having a port entryway, a sensor port configured to receive an analyte sensor through the port entryway, at least two electrodes disposed in the sensor port coupled to the electronic components via a sealed connection, and at least one wash port separate from the port entryway.

12. The analyte meter of claim 11, wherein a fluid flow channel is formed between the at least one wash port and the port entryway such that application of a liquid onto the at least two electrodes does not adversely affect the analyte meter.

13. The analyte meter of claim 10, wherein the replaceable battery cartridge attaches to the meter housing via a slidable insertion.

14. The analyte meter of claim 10, wherein the replaceable battery cartridge is configured to receive any one of a plurality of battery cartridge inserts of different battery chemistries.

15. The analyte meter of claim 10, wherein the electronic components comprise a processor and a memory.

16. A method of manufacturing an analyte meter, comprising:

enclosing electronic components for carrying out analyte measurements within a liquid-impermeable internal chamber of a meter housing; and

seating an analyte sensor electrical connector unit in a recessed pocket of the meter housing, the analyte sensor electrical connector unit having a port entryway, a sensor port configured to receive an analyte sensor through the port entryway, at least two electrodes disposed in the sensor port, and at least one wash port separate from the port entryway;

wherein the seating comprises coupling the at least two electrodes to the electronic components via a sealed connection such that application of a liquid onto the at least two electrodes does not adversely affect the analyte meter.

17. The method of claim 16, further comprising attaching a replaceable battery cartridge to the meter housing, the replaceable battery cartridge having a sealed battery connector to protect against liquid ingress into the internal chamber.

18. The method of claim 16, further comprising sealing a display screen to the meter housing to prevent fluids from entering the internal chamber.

19. The method of claim 16, further comprising sealing a keypad to the meter housing to prevent fluids from entering the internal chamber.
