Ingestible medical devices

A wide variety of wearable, implantable, and even ingestible medical devices are under development or in the early stages of clinical use. Here are just a few. 

For the general population, ingestion is the primary exposure pathway for cobalt. For persons working in industrial settings, inhalation is a significant pathway (e.g., carbide industry emissions and airborne particulate from grinding processes) as is dermal exposure. There can also be internal exposure from implanted medical devices. 

Do not use mouth-to-mouth method if victim ingested or inhaled the substance induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. 

Health Hazards Information - Recommended Personal Protective Equipment Individual breathing devices with air supply neoprene gloves protective clothing eye protection Symptoms Following Exposure Inhalation of concentrated gas will cause suffocation. Contact will liquid can damage eyes because of low temperature. Frostbite may result from contact with liquid General Treatment for Exposure INHALATION remove to fresh air use artificial respiration if necessary. EYES get medical attention promptly if liquid has entered eyes. SKIN soak in lukewarm water (for frostbite) Toxicity by Inhalation (Threshold Limit Value) Data not available Short-Term Exposure Limits Data not available Toxicity by Ingestion Not pertinent (boils at -24.7°C) Late Toxicity Data not available Vtqtor (Gas) Irritant Characteristics Data not available Liquid or Solid Irritant Characteristics Data not available Odor Threshold Data not available. 

The increased use of plastics in dentistry and medical implants calls for materials that can be detected and analyzed by rapid, nondestructive methods [1,2]. For example, ingested dentures or restorative dental materials made from radiolucent plastics cannot be easily detected by common radiographic diagnostic techniques. The difficulty to detect plastic fireweapons by current screening devices could be cited as another reason for the need of X-ray contrast or radiopaque resins.
