Pre-connected analyte sensors
Pre-connected analyte sensors are provided. A pre-connected analyte sensor includes a sensor carrier attached to an analyte sensor. The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.
1. An analyte monitoring device comprising:
a housing comprising a top portion and a bottom portion, wherein the bottom portion comprises one or more walls, wherein the one or more walls form a slot;
an analyte sensor comprising a distal portion configured for subcutaneous sensing and a proximal portion comprising one or more electrical contacts;
sensor electronics located in the housing between the top portion and the bottom portion;
an intermediate body electrically and mechanically connected to the analyte sensor and the sensor electronics;
a sensor insertion opening in the housing bottom portion and in the housing top portion forming a passage through the housing;
wherein the slot is positioned between the intermediate body and the passage;
wherein the analyte sensor extends from the intermediate body, through the slot, and to the passage;
wherein after the analyte sensor passes through the slot, the analyte sensor comprises a bend to extend away from the housing at or in the passage for insertion in the host; and
wherein the analyte sensor is secured in the slot with an adhesive between the intermediate body and the passage.
2. The analyte monitoring device of claim 1 , wherein the adhesive comprises a hardened, liquid dispensed adhesive material.
3. The analyte monitoring device of claim 1 , wherein the adhesive comprises an epoxy.
4. The analyte monitoring device of claim 1 , wherein the adhesive comprises a cyanoacrylate.
5. The analyte monitoring device of claim 1 , wherein the one or more walls are integrally molded with the housing bottom portion.
6. The analyte monitoring device of claim 1 , wherein the analyte sensor comprises at least one electrode.
7. A method of making a wearable analyte monitoring device, the method comprising:
fabricating a wearable housing configured to house sensor electronics, wherein the fabricating comprises fabricating a housing top portion with a sensor insertion opening therein, and fabricating a housing bottom portion with a sensor insertion opening therein and a slot adjacent thereto;
placing at least a portion of an ex vivo portion of a transcutaneous analyte sensor into the slot;
extending an in vivo portion of the transcutaneous analyte sensor from the slot and out of the housing via the sensor insertion opening;
dispensing a liquid adhesive material into the slot, and
hardening the dispensed liquid adhesive material to retain the at least a portion of the ex vivo portion of the transcutaneous analyte sensor in the slot.
8. The method of claim 7 , wherein the dispensing comprises dispensing an epoxy.
9. The method of claim 7 , wherein the dispensing comprises dispensing a cyanoacrylate.
10. The method of claim 7 , further comprising placing at least a portion of the ex vivo portion of the transcutaneous analyte sensor into an intermediate body that is configured to mechanically and electrically couple the transcutaneous analyte sensor to the sensor electronics.
11. The method of claim 7 , further comprising placing the at least a portion of the ex vivo portion of the transcutaneous analyte sensor into the slot before dispensing the liquid adhesive material into the slot.
12. The method of claim 7 , further comprising soldering contacts on the intermediate body to sensor electronics located in the housing.
13. The method of claim 7 , wherein the slot is formed by walls integrally molded with the housing bottom portion.
