The present invention relates to methods for operating a respiration apparatus and a respiration system, and also a respiration apparatus and a respiration system. The respiration system comprises a respiration apparatus and a computer software program for an external computer to operate the respiration apparatus. The respiration apparatus comprises a processor device and an apparatus software program and an apparatus configuration. The validities of the computer software, the apparatus software and the apparatus configuration are in each case characterized by a version. The versions are compared with one another to detect a version conflict. If invalid versions are present, the computer software is provided with a program component with a limit value and a plausibility rule, or the setting parameters are sorted into a first group and a second group. The setting parameters of the first group are retained.

A drive mechanism includes a housing, a piston adapted to impart movement to a plunger seal within a drug container, a plurality of biasing members disposed in parallel, and a retainer. The biasing members are disposed to release energy to cause movement of the piston from a retracted first position to the extended second position, the piston bearing against the plunger seal to dispense medicine. The retainer is disposed to maintain the biasing members in the energized position and to release the biasing members to permit the piston to dispense the medicine. The drive mechanism may also include an end-of-dose indicator to identify at least one of when the sleeve assembly is disposed subjacent a window in the housing, the relative motion of the sleeve assembly with reference to the window or another reference component, the stoppage of such motion, and the rated or change of rate of motion.

The present invention relates to a housing element (20) for a medicament delivery device (10), which housing element (20) comprises a mount (30) for releasably attaching an auxiliary unit (40), and wherein the mount (30) is integral with the housing element (20).

An external fluid communication apparatus that is placed adjacent to a surface, the fluid communication apparatus including a flexible surrounding sidewall having a first end portion and an opposing second end portion with a longitudinal axis therebetween, wherein the first end portion is adapted to connect to a fluid source containing a fluid and the second end portion is adapted to feed a consumer of the fluid with the sidewall operationally communicating the fluid from the first end portion to the second end portion, the sidewall further having an inner surface and an opposing outer surface. Further included in the external fluid communication apparatus is a flexible textured matte skin element disposed on the outer surface that is operational to not reflect ambient light.

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device to deliver fluid to a user in accordance with an operating mode involves obtaining operational information pertaining to one or more prior instances of the operating mode, obtaining status information pertaining to the infusion device, and determining a diagnosis time based at least in part on the operational information. The diagnosis time is prior to a subsequent instance of the operating mode. At the diagnosis time, the method automatically determines the viability of the subsequent instance of the operating mode based at least in part on the status information and automatically generates a notification indicative of a recommended action for the user based at least in part on the viability.

The present disclosure pertains to a system and method for monitoring usage of a respiratory medicament delivery device. Regular use of a respiratory medicament delivery device at intervals prescribed by a doctor may be critical to a subject's health. The system described herein is configured to monitor usage of a respiratory medicament delivery device such that manual tracking of a patient's adherence to a dosage plan by a doctor, for example, is not required. Monitoring usage of the medicament device delivery device may allow the doctor to judge the adherence of the subject to the dosage plan and encourage increased adherence. Improved adherence by the subject may result in improvement in the condition of the subject and economic benefits including reducing costs associated with re-hospitalization after discharge. In some embodiments, the system comprises a medicament delivery device and a usage event monitoring device.

The invention relates to a system for administering drug to a Parkinson's disease patient comprising (a) a drug; (b) a storing bag for the drug; (c) a pump for administering the drug; (d) a pump controller for controlling the pump activity, the pump controller having access to a correlation of a first parameter t.sub.x and a second parameter A.sub.t, and to the current first parameter t.sub.x, wherein the first parameter t.sub.x is correlated with a certain activity of the patient and the second parameter A.sub.t is correlated with a dosage of the drug and the pump controller controls the pump activity in dependence of the first parameter t.sub.x and the correlation, and/or wherein the system comprises (e) a storing hag the drug suitable for pre-filling and long-term oxidations-free storage having a multi layer wall with the internal layer made of EVA or cyclic polyolefines and at least one further layer made of EVOH.

A pen needle (501) includes a hub (531) and a needle (521) fixedly connected to the hub (531). An outer cover (511) removably receives the hub (531) and the needle (521). The outer cover (511) has a first gripping member (515) to facilitate removal of the outer cover (511) from the hub (511). A sealing member (541) is removably connected to the outer cover (511). The sealing member (541) has a second gripping member (543) to facilitate removal of the sealing member (541) from the outer cover (511). The first and second gripping members facilitate manipulation of the pen needle by a user with reduced dexterity or a physical or visual impairment.

A drive mechanism includes a housing, a piston adapted to impart movement to a plunger seal within a drug container, a plurality of biasing members disposed in parallel, and a retainer. The biasing members are disposed to release energy to cause movement of the piston from a retracted first position to the extended second position, the piston bearing against the plunger seal to dispense medicine. The retainer is disposed to maintain the biasing members in the energized position and to release the biasing members to permit the piston to dispense the medicine. The drive mechanism may also include an end-of-dose indicator to identify at least one of when the sleeve assembly is disposed subjacent a window in the housing, the relative motion of the sleeve assembly with reference to the window or another reference component, the stoppage of such motion, and the rated or change of rate of motion.

According to one or more embodiments, a system is provided. The system includes a power device implantable within a patient for powering an implantable medical device. The power device includes a first coil configured to receive wireless power signals for powering the implantable medical device and processing circuitry configured to determine at least one measurable electrical characteristic in a plurality of electrical pathways in the power device including an electrical pathway to the first coil, and detect reduced performance in receiving wireless power signals based at least in part on the determined at least one measurable electrical characteristic.
