Abstract
An automated wearable device measure physiological signals, and when parameters which cause the wearer to be at risk are measured, the device delivers an antidote for a given medical condition. This prevents overdose or medical conditions from occurring.
Claims14
A wearable medication delivery device comprising:
- a housing;
- a band connected to the housing for attaching the housing to a patient;
- a compressed gas cylinder located inside the housing;
- a piston chamber in fluid communication with the gas cylinder, the fluid path having a gas release valve;
- a piston located in the piston chamber;
- a medication-filled syrette operably connected to the piston;
- a battery to power the device;
- a vital sign sensor;
- and
- a central processing unit configured to actuate the valve to release the gas, forcing the syrette into the skin, injecting the wearer with the medication, in response to a change in vital signs.

A nasal spray device comprising:
- a set of clips configured to spray an antidote into the sinuses;
- a compressed gas cylinder containing the antidote;
- a spray control valve connected between the cylinder and the clips;
- a central processing unit attached to the cylinder having a breathing sensor and a radio emitter;
- and
- wherein the processing unit is configured to activate the valve to release of the antidote as a nasal mist directly into the sinuses in response to the breathing sensor.
3 more elements
A device for spraying an antidote toward a face comprising:
- a face mask comprising a transparent face and upper and lower attachment rods for securing the mask to the head;
- a compressed gas cylinder containing the antidote, the cylinder being attached to the mask;
- a conduit connected between the cylinder and the inside of the mask to release a mist of opiate overdose antidote as a nasal mist into the mask;
- a spray control valve connected between the cylinder and the conduit;
- a central processing unit attached to the mask configured to receive information from sensors capable of detecting an overdose;
- and
- a radio-emitter connected to the central processing unit, the emitter capable of emitting radio signals with medical information about the wearer when the sensors detect an overdose.
