Abstract:
An inhaler for delivery of a medicament by inhalation is disclosed. The inhaler comprises a dispensing mechanism, the dispensing mechanism being configured, on actuation, to dispense a dose of medicament, a dose counting mechanism comprising a counter for displaying indicia relating to the number of doses of medicament of the inhaler. The inhaler further comprises a window substantially aligned with the counter such that the indicia are viewable therethrough, wherein the window comprises a magnifying outer surface for magnifying the indicia of the counter, the magnification in a first dimension being greater than the magnification in a second dimension that is substantially perpendicular to the first dimension.
Abstract:
A dose setting mechanism (4; 200) for a drug delivery device is disclosed. The mechanism comprises an outer housing (40; 204) and an inner housing (208) having an external groove. The inner housing guides a driver (30; 209) to dispense a set dose. A dial sleeve (1 0; 206)is disposed between the outer and inner housing and is rotatably engaged with the inner housing. When a dose is set, the dial sleeve is rotated and translates away from both the outer housing and the inner housing.
Abstract:
A portable hemodialysis system is provided including a disposable cartridge and a reused dialysis machine. The disposable cartridge includes a dialysate flow path and a blood flow path which flow in opposite directions through a dialyzer. The disposable cartridge further includes a filter for removing waste products from the dialysate as well as one or more flow sensors for measuring the flow of dialysate in the dialysate flow path. The preferred flow sensor includes a rotatable spoked wheel in the dialysate flow path which is rotated by the flow of dialysate. The spoked wheel includes one or more magnets which are rotated with the rotation of the spoked wheel. The flow sensor further includes a magnetic field sensor in the reused dialysis machine which is connected to a processor for monitoring the rotation of the spoked wheel to determine flow of fluid in the dialysate flow path.
Abstract:
A method of flowing a medicament containing powder using gas, including, providing a volume of a gas according to one or more release conditions; directing flow of said gas through or adjacent a powder including a medicament; and releasing a therapeutically effective amount of said powder using said gas. Optionally, the releasing comprises releasing according to breath considerations. Optionally or alternatively, the releasing comprises releasing according to time considerations. In an exemplary embodiment of the invention, the powder is held in a capsule that has apertures formed therein.

Abstract:
A non-burning type flavor inhaler, comprises: a housing having an airflow path that continues from an inlet to an outlet; an atomizer configured to atomize an aerosol source without burning; a sensor including a capacitor, the sensor outputting a value indicating electric capacitance of the capacitor, the electric capacitance changed depending on a puff action of a user; and a controller configured to detect a start or an end of a puff duration on the basis of an output value that is output from the sensor. The controller detects the start or the end of the puff duration when an inclination formed by two or more of the output values has a predetermined sign and when an absolute value of the inclination having the predetermined sign is larger than a predetermined value.
Abstract:
A healthcare enterprise has an associated management resource that manages operation of one or more medical devices in the healthcare enterprise. To determine what functionality to enable in a respective medical device, the respective medical device establishes a communication link to communicate in a network environment. Subsequent to establishing the communication link, the medical device initiates communications over the communication link from the medical device to the remotely located management resource. The communications include a unique identifier value assigned to the medical device. Depending upon feedback (such as granting or denial of authorization) from the management resource with respect to the unique identifier value, the medical device operates in one of multiple different operational modes such as a fully functional mode or a reduced functionality mode.
Abstract:
Some embodiments of an infusion pump system may be configured to provide a desired level of resistance to liquid ingress to the pump casing while contemporaneously providing air transmissibility for equalization of air pressure differentials between the interior and exterior of the pump casing. Further, some embodiments can detect when moisture inside a casing of the infusion pump system is greater than or equal to a threshold level and can initiate one or more patient safety countermeasures.
Abstract:
The present invention relates to a pharmaceutical injection device, and it is an object thereof to make this device easier to use, such as by opening a cartridge holder automatically. In order to achieve this object, the pharmaceutical injection device of the present invention comprises a cartridge holder (7), a main case (1), a piston (10), a motor (13), an opening component (130), an open/closed detection switch (24), and a controller (25). The motor (13) drives the piston (10) in either an insertion direction (C) in which the piston (10) is inserted into a pharmaceutical cartridge (9), or a pull-out direction (D) in which the piston (10) is pulled out of the pharmaceutical cartridge (9). The opening component (130) opens the cartridge holder (7) in conjunction with the movement of the piston (10) in the pull-out direction (D). The open/closed detection switch (24) detects whether the cartridge holder (7) is open or closed. When the open/closed detection switch (24) detects that the cartridge holder (7) is open, the controller (25) controls the motor (13) so as to stop the piston (10).
