Runatek is a medical device startup that has developed a smart device (the Sotiras) that regulates the concentration of opioid pain medication in a patient’s system when they’re recovering from a major surgery, such as a total joint replacement (TJR). This ensures that the patient does not misuse the medication or develop an addiction by leveraging proprietary sensing methods to determine the concentration of medication in a patient’s system and provide subcutaneous doses of medication to maintain a doctor-prescribed setpoint in an outpatient setting.
