Abstract

Claims (22)

1 . A modular wearable device for patient monitoring and drug delivery, the modular wearable device comprising:

a fastening portion configured to removably affix the modular wearable device to a portion of a patient;

a plurality of module receiving portions configured to receive removable modules;

a first removable module comprising a physiological sensor; and

a second removable module comprising a first drug delivery reservoir and a pump in fluid connection with a cannula and the first drug delivery reservoir, the pump configured to deliver liquid drug from the first drug delivery reservoir to the patient, wherein the first drug delivery reservoir is configured to deform as liquid drug is dispensed,

wherein the first module and the second module are in communication.

2 . The modular wearable device of claim 1 , wherein the modular wearable device is configured to removably affix to at least one of: the patient's arm, the patient's leg, the patient's waist, or the patient's chest.

3 . The modular wearable device of claim 1 , wherein the module receiving portions are configured to accept, hold, and release the removable modules.

4 . The modular wearable device of claim 1 , further comprising a third removable module comprising a battery, the modular wearable device comprising a power connection between the battery and at least one other removable module.

5 . The modular wearable device of claim 1 , comprising a third removable module comprising a wireless module.

6 . The modular wearable device of claim 5 , wherein the wireless module comprises at least one of: an optical transceiver, an acoustic transceiver, a Bluetooth transceiver, a GPS transceiver, a Wi-Fi transceiver, or a wireless broadband transceiver.

7 . The modular wearable device of claim 1 , wherein the physiological sensor comprises an external detector configured to removably affix to the patient.

8 . The modular wearable device of claim 1 , wherein the physiological sensor comprises at least one of: an analyte sensor, an inertial measurement sensor, a skin impedance sensor, a microphone, a haptic sensor, an optical sensor, a pulse measurement sensor, a diffuse reflectance sensor, or a Raman sensor.

9 . The modular wearable device of claim 8 , wherein the analyte sensor comprises at least one of: a glucose sensor, a lipid sensor, a lactic acid sensor, a ketone sensor, an oxygen sensor, or a carbon dioxide sensor.

10 . The modular wearable device of claim 1 , wherein the drug delivery reservoir comprises insulin, hyaluronidase, or an analgesic.

11 . The modular wearable device of claim 1 , wherein the modular wearable device comprises a fluid channel configured to inject a liquid drug into the patient.

12 . The modular wearable device of claim 11 , wherein the fluid channel is configured to resist deformation.

13 . The modular wearable device of claim 11 , wherein the modular wearable device comprises a second fluid channel connecting the first drug delivery reservoir to a second drug delivery reservoir.

14 . The modular wearable device of claim 13 , wherein the second fluid channel is configured to mix liquid drug from the first drug delivery reservoir and second drug delivery reservoir.

15 . The modular wearable device of claim 13 , wherein the second fluid channel is configured to resist deformation.

16 . The modular wearable device of claim 1 , wherein the modular wearable device comprises a signaling connection between the physiological sensor and at least one other module.

17 . The modular wearable device of claim 1 , wherein the modular wearable device comprises a flexible material that is configured to conform to an attachment site on the patient.
