A drug solution injection needle includes: a distal end member being a sharp member and made of metal; a connecting tube having electrical insulating properties connected to a base end side of the distal end member; a metal tube connected to a base end side of the connecting tube; and an insulating layer covering an outer circumferential surface of a base end portion of the metal tube. The connecting tube and/or the distal end member includes at least one hole communicating with a cavity of the drug solution injection needle and open to an outer surface of the connecting tube or the distal end member, and an electrode configured to measure electric potential is formed by a distal end portion of the metal tube not covered by the insulating layer.

Techniques disclosed herein relate generally to notification generation in a medical device system. In some embodiments, the techniques involve generating a first notification via a medical application executing on a first device, determining that the first notification was not acknowledged within a predetermined time frame, and causing generation of a second notification at a medical device carried by a user to notify the user that the first notification has not been acknowledged.

A computer-implemented diabetes management method includes a first determination of an insulin bolus related to one or more obtained glucose values and optionally the expected carbohydrate content of a meal to be ingested, a re-calculation of an insulin bolus in consideration of a user's body parameter information as measured by a body-worn sensor, providing a notification to the user if there is a significant deviation between the two calculated bolus amounts, and a user input whether the calculated insulin bolus or the re-calculated insulin bolus is selected by the user for bolus administration.

An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.

An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service. The opioid overdose monitoring service notifies a first set of contacts when the opioid monitoring information indicates a non-distress stats and notifies a second set of contact when the opioid monitoring information indicates an overdose event. The notification can be a phone call or text message to a specified person, emergency personnel, or first responders, and can include the location of the smart mobile device. The smart mobile device can also include the location of the nearest treatment center having emergency medication used in treating opioid overdose, such as naloxone.

Systems and methods for injecting a drug and detecting tissue induced back pressure are disclosed. A drug delivery system may include a reservoir filled or fillable with a drug, an administration member connected or connectable in fluid communication with the reservoir, a drive assembly, and a pressure sensor. The administration member may be configured for insertion into and subsequently retraction from a patient. The drive assembly may be configured to urge the drug from the reservoir to deliver a dose of the drug to the patient via the administration member. The pressure sensor may be configured to detect tissue back pressure during use of the drug delivery system, including after dose completion and prior to retraction of the administration member. The drug delivery system may be controlled in a manner that accounts for the tissue back pressure measurement.

An implantable emergency management drug delivery system configured to deliver a medicament to reverse the effects of a drug overdose. The implantable emergency management drug delivery system including an implantable infusion pump configured to infuse a first medicament, and an emergency handling device having at least one physiological sensor configured to monitor a condition of a patient for a possibility of an overdose from the first medicament, a communication module configured to communicate the possibility of an overdose to the implantable infusion pump, and an implantable medicament delivery mechanism configured to deliver a second medicament to reduce one or more adverse physiological effects of the first medicament.

A medical device system. The system includes a first medical device, a first remote interface, and a second remote interface in communication with the first remote interface and the first medical device, wherein the first medical device sends a command to the first medical device through the second remote interface, and wherein when the second remote interface receives the command, the command must be confirmed by the second remote interface before the command is send by the second remote interface to the first medical device.

Electrochemical Impedance Spectroscopy (EIS) is used in conjunction with continuous glucose monitors and continuous glucose monitoring (CGM) to enable in-vivo sensor calibration. gross (sensor) failure analysis, and intelligent sensor diagnostics and faith detection. An equivalent circuit model is defined, and circuit elements are used to characterize sensor behavior.

A cannula for subcutaneous dispensing of medicaments, wherein the cannula has a cannula wall, a distal end and a proximal end and wherein the cannula comprises a single orifice in the cannula wall, proximal to the distal end of the cannula or two or more orifices in the cannula wall, proximal to the distal end of the cannula.
