A dose setting mechanism for a medicament delivery device, which dose setting mechanism comprises, a tubular member 10 having a longitudinal track 18 of a predetermined length; a dose drum 40, coaxial with the tubular member 10, and being axially and rotationally movable relative to the tubular member 10; a stop member 90, axially movable but rotationally locked relative to the tubular member 10, and further being in an axially slaved connection with the dose drum 40; wherein said stop member 90 comprises a track follower 98 in engagement with the longitudinal track 18, such that rotational movement of the dose drum 40 relative to the tubular member 10 may cause a maximum axial displacement of said dose drum 40 and said stop member 90, relative to the tubular member 10, corresponding to said predetermined length.

The present disclosure relates in one aspect to a measuring arrangement for measuring a volume occupied by a liquid medium inside a liquid reservoir, the measuring arrangement including a container having an interior volume containing a gas reservoir filled with a gaseous medium and containing a liquid reservoir filled with a liquid medium, wherein the gas reservoir and the liquid reservoir are hermetically separated by an impenetrable separation wall, a volume modulator to induce a volume change of the gas reservoir, a pressure sensor arranged inside the gas reservoir to measure a pressure change of the gaseous medium in response to the volume change of the gas reservoir, and a controller connectable to the pressure sensor, wherein the controller is configured to calculate the volume of the liquid reservoir on the basis of the pressure change and the volume change.

A device for administering needle-free subcutaneous treatment to a patient comprises an actuator configured to deliver a plurality of volumes of a treatment at a plurality of locations on a body of the patient; at least one imaging device configured to detect a movement of the needle-free device from a first location on the body of the patient to a second location on the body of the patient; and a processor configured to determine the second location on the body of the device relative to the first location from the movement of the needle-free device relative to the first location on the body, the processor further configured to determine a volume of the plurality of volumes of the treatment to deliver to the body of the patient at the second location.

A methodology to track patient usage of an autoinjector (AI) device, and to an external or electronic adaptor (eAdaptor) adapted to be used with the AI are disclosed. The eAdaptor contains sensors (including but not limited to a temperature sensor, a sound sensor, a vibration sensor and a magnetic sensor system), a display, a microprocessor, a real time clock, and communication systems that enables the eAdaptor to capture and confirm autoinjector (AI) use, as well as injection information, and transmit such information wirelessly to a smart phone or any other data receiving system or device. Also disclosed are an internal logic to operate the eAdaptor and a smart device APP that pairs with the internal logic to guide the patients with graphical user interface (GUI) displays on the smart device.

The invention relates to an injection unit, preferably a pen-shaped injection unit, for administering or delivering a fluid product. The injection unit comprises a housing, an axially movable piston rod mounted in the housing in a non-rotatable manner, a delivery apparatus having a threaded nut that is able to move the piston rod in order to deliver product, a dosing device having a dosing sleeve, a rotary knob, a discharge button arranged coaxially on the dosing sleeve, and a receptacle for the product. The dosing device is connected to the delivery apparatus via a coupling mechanism, wherein the coupling mechanism includes of at least two coupling surfaces that each carry a toothing comprising teeth, wherein the coupling surfaces are used to generate an acoustic and/or tactile signal corresponding to the set or corrected dose of the product to be administered during the dosing operation or during correction of the dose.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a method includes receiving one or more analyte values associated with a health condition of the patient user; receiving contextual data associated with the patient user obtained by the mobile computing device, where the obtained contextual data includes information associated with a meal; determining a medicine metric value associated with an amount of medicine active in the body of the patient user; autonomously calculating a dose of the medicine without input from the user based at least on the one or more analyte values, the medicine metric value, and the information associated with a meal; and continuously displaying the calculated dose of the medicine.

The disclosure relates to an injection device for expelling of a number of preset or user-selectable doses of a medicament. The injection device includes an elongated housing extending along an axial direction and configured to accommodate a cartridge containing the medicament and having a bung sealing a proximal end of the cartridge, a windup expelling mechanism, and a dose setting mechanism. The dose setting mechanism includes a handle, a dose tracking member, and a limiter.
