A medical system comprising: an analyte sensor for receiving an analyte signal corresponding to an analyte concentration of a user; a health monitor device comprising a display unit and in communication with the analyte sensor, the health monitor device comprising a processor and memory communicably coupled to the processor, the memory including instructions stored therein that, when executed by the processor, cause the processor to: receive the analyte signal from the analyte sensor; determine the analyte concentration based on the analyte signal; calculate a recommended medication dosage based on the analyte concentration; associate a current parameter type with the recommended medication dosage; associate the current parameter type to at least one corresponding stored historical parameter type associated with a historical medication dosage; and display, on the display unit, the recommended medication dosage and the historical medication dosage.

A method of delivering epinephrine includes placing a distal end surface of a medical injector into contact with a target location of a patient. The medical injector includes a housing, an energy storage member, and a medicament container containing a dose of epinephrine effective for administration to the patient experiencing anaphylaxis and having a weight of less than 15 kg. The medicament container is coupled to a needle. The medical injector is actuated such that the energy storage member produces a force to move the needle from a first needle position to a second needle position. A distal tip of the needle extends from the distal end surface by a distance of between 7 millimeters and 8 millimeters when the needle is in the second needle position. A portion of the force is exerted to expel the dose of epinephrine when the needle is in the second position.

An attachment for a drug injection pen includes a housing shaped to attach to a proximal end of the drug injection pen, and a dosage measurement system disposed at least in part within the housing. The dosage measurement system is coupled to receive a rotational motion, from a dosage injection mechanism disposed within the drug injection pen, when the drug injection pen dispenses a fluid. The dosage measurement system includes one or more magnets to generate a magnetic field, and one or more magnetic field sensors. The one or more magnetic field sensors rotate relative to the one or more magnets when the drug injection pen dispenses a fluid, and output a signal indicative of the magnetic field.

An assembly for a drug delivery device is provided comprising a screw member comprising a thread, the thread including at least two consecutive portions, the portions having different leads. The device further includes a nut member. The assembly is configured such that, in a first portion of the thread, the nut member includes a first position with respect to an axis transversal to the rotational axis and in a second portion of the thread, the nut member includes a second position with respect to the axis transversal to the rotational axis. The nut member is configured to perform a tilting movement from the first position into the second position when the nut member passes from the first portion to the second portion. Furthermore, a drug delivery device comprising the assembly is described.

The present invention relates to a pre-filled syringe containing Moxifloxacin has a plunger, a barrel, a needle with gauge, kits having this syringe and the use of the syringe for the administration of Moxifloxacin for postsurgical bacterial endophthalmitis after cataract surgery.

A drive mechanism suitable for use in drug delivery devices is disclosed. The drive mechanism may be used with injector-type drug delivery devices, such as those permitting a user to set the delivery dose. The drive mechanism may include a housing, a dose dial sleeve, and a drive sleeve. A clutch is configured to permit rotation of the drive sleeve and the dose dial sleeve with respect to the housing when the dose dial sleeve and drive sleeve are coupled through the clutch. Conversely, when the dose dial sleeve and drive sleeve are in a de-coupled state, rotation of the dose dial sleeve with respect to the housing is permitted and rotation of the drive sleeve with respect to the housing is prevented. In the de-coupled state, axial movement of the drive sleeve transfers force in a longitudinal direction for actuation of a drug delivery device.

A drug delivery system for injecting a medicament includes a container including a closure and a stopper configured to move within the container from a pre-use position to a post-use position. The system includes a drive assembly configured to move the stopper between first and second positions, and a spacer assembly engaged with the stopper configured to be engaged by the drive assembly. The spacer assembly includes a first spacer portion received within the stopper, a second spacer portion spaced from the first spacer portion, an inner plunger, and a spacer shuttle received by the inner plunger. The inner plunger, the spacer shuttle, and the second portion are configured to move relative to the stopper, where movement of the second spacer portion is restricted by the spacer shuttle, movement of the spacer shuttle is restricted by the inner plunger, and movement of the inner plunger is restricted by the stopper.

An injection device including: a body including a syringe locator for receiving a syringe; and a firing mechanism including a rear cap, a plunger configured to be axially displaced in a forward direction relative to the rear cap and a driver system for driving the plunger forwards upon activation of the injection device, the firing mechanism configured to be directly or indirectly connected to the body such that an axial spacing of the rear cap and a barrel of the syringe is fixed during operation of the injection device, wherein, the firing mechanism and/or the body include first and second connection features allowing adjustment of a relative axial position of the firing mechanism and the syringe locator during assembly of the injection device.

Methods, systems and devices for detecting an analyte sample, determining an analyte concentration associated with the detected analyte sample, storing the determined analyte concentration and a time associated with the determined analyte concentration, retrieving two or more stored analyte concentrations, and determining an adjusted dose level based at least in part on a current dose level and data associated with the two or more retrieved analyte concentrations are provided. For example, adjustments to dosage levels of long-acting insulin may be provided to assist in the management of diabetes and related conditions.
