A drug overdose detection apparatus that is configured to measure the blood oxygen level of a user and upon detection in a drop thereof provide administration of a substance to counteract the drug overdose. The present invention includes a housing that is configured to be worn by a user has an interior volume. Disposed in the interior volume of the housing is a substance administration assembly wherein the substance administration assembly includes a syringe member, a plunger member and a plunger driver. A motor is operably coupled to the plunger driver and facilitates movement thereof. A spring needle assembly is operably coupled to the substance administration assembly and includes a spring biased needle that is operable to inject into a patient so as to inject the substance. The present invention further includes an audio alarm and transceiver configured to provide alerts and transmit signals.

A medical device comprising an infusion device comprising a fluid reservoir to contain a therapeutic fluid and a transcutaneous access tool fluidly coupled to the fluid reservoir, the transcutaneous access tool configured to deliver the therapeutic fluid subcutaneously to a patient; wherein the infusion device operates in a stand-by mode prior to the therapeutic fluid being introduced into the fluid reservoir; wherein the infusion device operates to deploy the transcutaneous access tool within a predetermined deployment time period upon filling the fluid reservoir to a predetermined fill level with the therapeutic fluid.

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 injection system is described that receives, from one or more sensors, a first group of one or more signals indicating a current volume of injection fluid dispensed from a fluid reservoir at a first time. The injection system determines, based on the first group of one or more signals, that a difference between a dispensed volume limit and the current volume of the injection fluid dispensed from the fluid reservoir at the first time is less than a necessary volume of fluid required to complete both a systolic injection phase and a diastolic injection phase. The injection system further, responsive to determining that the difference is less than the necessary volume of fluid required to complete both the systolic injection phase and the diastolic injection phase, controls the injection system to refrain from performing each of the systolic injection phase and the diastolic injection phase.

Systems and methods are disclosed herein for switching an application executing on an ambulatory medical device to a new application without interrupting therapy provided by the ambulatory medical device to a subject. The ambulatory medical device may receive an indication that an update to an application executing on the ambulatory insulin pump is available, establish a communication connection to a host computing system, download and install the application update, while a prior version of the application continues to run. The disclosed systems and methods can confirm successful installation of the application update on the ambulatory medical device and switch control of the ambulatory medical device from the prior version to the new version of the application without interrupting therapy provided to the subject.

A patch injection device comprising a housing, an adhesive substrate having a first surface with a first surface area for skin attachment and a second surface which is opposite the first surface attaching partly to the housing and a removable release liner. The surface area of the second surface attaching to the housing is smaller than the first surface area and the excess area defines a skirt of the substrate at least partially surrounding the housing. The first surface of the substrate attaches to the removable release liner which fully covers the first surface area of the substrate. Furthermore a pull tab is provided being part of the release liner and located in a cut-out of the skirt of the substrate such that a peel force is transmittable from the release liner to the housing at the location where the cut-out reaches the housing.

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

Apparatus and methods are operative to probe the condition of a sensor either initially, at any point thereafter or continuously during a continuous sensor operation for measuring an analyte in a bodily fluid (such as performed by, e.g., a continuous glucose monitoring (CGM) sensor). Results of the probe may include calibration indices determined from electrical signals obtained during the probe. The calibration indices may indicate whether in-situ adjustment of the sensor's calibration should be performed either initially and/or at random check points. Probing potential modulation parameters also may be used during analyte calculations to reduce the effects of lot-to-lot sensitivity variations, sensitivity drift during monitoring, temperature, interferents, and/or the like. Other aspects are disclosed.

A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

A monitoring device for monitoring a hypocortiolism patient, the monitoring device comprising:a needle for penetrating a skin of the patient, andan analysis module fluidly connected with the needle, the analysis module comprising: o a first sensor, for measuring an inflammation level representative for the patient; and/or o a second sensor, for measuring a stress level representative for the patient; and wherein the monitoring device is configured to automatically trigger a notification in response to the first sensor measuring an inflammation level exceeding a first pre-defined threshold and/or in response to the second sensor measuring a stress level exceeding a second pre-defined threshold.
