FIELD OF THE INVENTION 
       [0001]    The field of the invention is medical devices. 
       BACKGROUND OF THE INVENTION 
       [0002]    Opiate addiction is the leading cause of death among adults under twenty four in many regions of the United States. Opiates are powerfully addictive since they bind with greater affinity than the body&#39;s natural dopamine. The majority of opiate users today start their addiction with prescription drugs. When they can no longer afford prescription opiates, they often turn to heroin use. According to the Center for Disease Control, 44 Americans die every day in the US from opiates. 
         [0003]    Drug overdose is caused by a variety of effects on the body. Opiates slow down breathing, heart rate, and drop blood pressure to fatal levels. The opiate user is impaired and incapable of self-administering antidote such as adrenaline or naloxone. In addition, medical professionals such physicians and emergency-medical-technicians are often unaware of the causes of the loss of consciousness and may accidentally mis-prescribe the intervention procedure. 
         [0004]    Much of the prior art is driven by the desire to deal with chronic conditions, such as diabetes, or constant medication for a given conditioning, in order to reduce the labor associated with repeated regular treatment. 
         [0005]    Syringe-based injection systems exist in a variety of applications in the public domain. Bryant Jr et al. in U.S. Pat. No. 9,132,227 describe an infusion pump for the introduction of liquids intravenously. In U.S. Pat. No. 9,114,208 describes a medication delivery device with a cartridge system. In U.S. Pat. No. 9,101,707 an implantable delivery system for bio-secretions. 
         [0006]    The inventors in U.S. Pat. No. 9,095,650 have a precision piston syringe system. In U.S. Pat. No. 9,067,047 a programmable injection system is described by the inventors. These are all developments which seek to attain automation or continuous drug delivery. In U.S. Pat. No. 9,061,097 Holt et al. U.S. Pat. No. 9,061,097 a wearable drug delivery system is described. it has a disposable cartridge system for single dosage use. Chong et al. U.S. Pat. No. 8,979,808 describe an on-body injection device. Sonderger et al. describe a device with a rechargeable syringe delivery system. In another invention in the prior art, Trembly III et al, U.S. Pat. No. 8,747,358 describe an injection system with manual control instead of automation. This allows control by the patient or care giver, especially when the prior is disabled or unable to use a loose syringe. 
       OBJECTS OF THE INVENTION 
       [0007]    One object of the invention is to develop an automated injection system which uses vital signs to be activated. Yet another object of the invention is to develop a wearable drug delivery system. Yet another object of the invention is to develop a device for opiate overdose prevention. Another object of the invention is to develop a device which radio signals medical professionals with information from an overdosing patient. Yet another object of the invention is to block opiate overdose by means of nasal spray vectored antidote. 
       SUMMARY OF THE INVENTION 
       [0008]    The invention is a wearable band containing an electronic vital-signs detector linked to an electronic activated drug syrette. When the wearers blood pressure and pulse drop off indicating an overdose, the syrette with antidote is activated and administered automatically. 
     
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0009]    A wearable band contains electrodes or other sensors to detect pulse and blood pressure levels. This data is sent to a small central processing unit contained inside the band. The device contains an injectable syrette with medication which is automatically injected when the device registers abnormally low pulse or blood pressure. When this occurs, a radio signal is emitted which allows for the wearer to both be located, and pre-diagnosed by medical personnel en route to the location. The radio signal contains the location of the wearer, the blood pressure, and pulse, as well as an announcement that the condition is drug induced. 
       EXAMPLES 
       [0010]    In a preferred embodiment of the invention, illustrated in  FIG. 1 , the unit is a rectangular flat device with lateral attached rods which serve as band attachment points. The device is 2 inches squared in surface area an one inch to one-half inches thick on it&#39;s profile. The rectangular device housing contains a small central processing unit which has wire relays to a radio-emitter, a gas-release valve, and two blood pressure and pulse sensors. When the blood-pressure and pulse sensors measure values and frequency which indicate that the wearer is undergoing an overdose, the central processing unit simultaneously open a gas release valve which sends pressurized gas powered syrette into the limb of the wearer, emptying the syrettes contents into the bloodstream, while simultaneously sending out an emergency radio signal indicating where the wearer is, and what the physiological data is, and that the wearer is a drug user, to prepare the medical intervention. 
         [0011]    The syrette is in the configuration of a thumb tac. The reservoir is flush with the edges of the cylinder, which when filled with compressed gas, acts as a gas-piston to drive the syrette down through a permeable membrane, and further compresses the compressible syrette to inject the medication. Preferred embodiments include the use of noxalone and adrenanline as opiate antidotes. The central processing unit has a built in battery or uses a small hearing aid battery to power normal function and emergency activation. A small pressurized replaceable gas cylinder fits into a chamber which is connected by the syrette cylinder by a small gas channel controlled by an electrically activated gas-release valve. The central processing unit only activates the valve release as well as the radio emitter in critical physiological function declines past acceptable levels. Once this occurs, pressurized gas is released from the compressed gas cylinder via a gas release valve controlled by the central processing unit. This gas plunges the syrette into the wearer, and further gas compression collapses the reservoir injecting the drug. The radio emitter simultaneously emits a signal. 
         [0012]    In another preferred embodiment the opiate antidote medicine is supplied as a nasal mist via a mask or a nose-clip. 
         [0013]    In another preferred embodiment an armband holds a syringe box which is held flat while not activated, and is pulled into a perpendicular position by a tightening retractable armband and further compressed to inject the antidote(s) into the wearer. 
         [0014]    The information obtained by the monitoring device are analyzed by the device computer central processing unit and a diagnosis can be made according to preset algorithms. It then trigger the delivery of the treatment drugs. There may be multiples drugs contained in one delivery system for several different emergency conditions. 
         [0015]    This device may be synchronized with an automatic external defibrilator during cardio-pulmonary recessitation in order to automatically administer medication when needed.
