Abstract:
An active agent injecting device dispenses a measured amount of active agent into a living organism. The injecting device includes a main housing, an injection assembly and a trigger mechanism. The main housing houses the operative components of the device. The needle encloses a carrier having an active agent disposed thereon. The trigger mechanism triggers the injection assembly to release the needle to inject the active agent into the living organism.
Abstract:
A dispensing device, a storage device and a method are proposed for dispensing a formulation as a spray. The formulation is dispensed by means of a gas stream. To improve the dispensing effect, pressure pulses are generated in the gas stream and/or the direction of gas flow alternates. The formulation is dispensed through a duct. The duct is connected to a storage chamber containing the formulation via a sharp edge or transition portion.
Abstract:
A nasal delivery device for delivering substance to a nasal cavity of a subject, the delivery device comprising : a substance supply unit for supplying a dose of substance to be delivered to the nasal cavity of the subject, the substance supply unit including an inlet and an outlet; a nosepiece unit including a nosepiece for fitting to a nasal cavity of the subject and being in fluid communication with the outlet of the substance supply unit; and a mouthpiece unit including a mouthpiece in fluid communication with the inlet of the substance supply unit and through which the subject in use exhales such as to entrain substance from the container chamber and deliver the same through the nosepiece, and at least one temperature modifier for reducing a temperature of the exhaled air flow such as to reduce the absolute humidity thereof.
Abstract:
An active agent or drug injecting device (10) includes a main housing (16) containing a trigger mechanism (24) which can be manually activated via release bar (32) or remotely triggered via wireless receiver (70) activating motor (74), and a second housing (80) containing an injection- and needle-assembly (22). The needle (30) encloses a dry carrier (26) having an active agent (12) disposed thereon. The trigger mechanism triggers the injection assembly to propel the needle into the skin (via spring (54)), to inject the active agent into a living organism (either by letting the active agent diffuse out of the needle or by actively flushing it out), and to subsequently retract the needle back into the housing (80) (via spring (64)).
Abstract:
A breathing assistance system (10) for providing breathing assistance to a patient (12) includes a gas delivery system (14) configured to generate a gas flow, a patient interface (16) configured to interface with the patient (12), a connection system (18) connected between the gas delivery system (14) and the patient interface (16) and configured to communicate the gas flow to the patient interface (16) for delivery to the patient (12), and a sensor system (20) remote from the gas delivery system and connected to at least one of the patient interface (16) and the connection system (18). The sensor system (20) may include a sensor (26) for measuring a parameter, one or more actuators (42), and a power supply based on a turbine (28) configured to be driven by the gas flow and an electrical generator (30) coupled to the turbine (28) and configured to generate electricity.
Abstract:
There is described a medicament delivery assembly which comprises mouthpiece provided with an air amplifier and a primer source, wherein the mouthpiece and the air amplifier are each is connected to the primer source via an actuatable valve; the air amplifier is also provided with a medicament extraction tube such that when the actuatable valve is opened then the primer source is activated and causes air to flow to the air amplifier. There is also described a method of administering a medicament which comprises the use of such a medicament delivery assembly.
Abstract:
A medicament delivery device (10) comprising a syringe (12) having a barrel with an open end, and an axially moveable stopper (18) received in the barrel separating a first chamber axially forwards of the stopper from a second chamber axially rearwards of the stopper. The medicament delivery device further including an expandable drive housing (24) arranged to receive a propellant from a propellant source (36) for providing a vapour pressure, the expandable drive housing having a narrow channel in fluid communication with the second chamber. The expandable drive housing is expandable upon receiving propellant from the propellant source and, upon expansion, causes forward axial movement of the syringe. Propellant introduced into the expandable housing may pass through the narrow channel into the second chamber and cause forward axial movement of the stopper in the barrel to expel medicament contained in the first chamber through the open end, where axial movement of the stopper in the barrel commences after axial movement of the syringe.
Abstract:
A medication reservoir is contained within a nebulizer body. An air line includes a distal end within the nebulizer body and venturi nozzle. A medication suction line extends from the medication reservoir to the venturi nozzle through which medication is drawn upward and mixed with air after passing through the venturi nozzle and nebulized for discharge through the nebulizer outlet. A valve is positioned within the air line proximal to the venturi nozzle and normally configured in a closed position until a negative inspiratory pressure is applied by a user to open the valve and allow air through the air line and venturi nozzle from a source of air and draw medication upward through the medication suction line for nebulization and discharge through the nebulizer outlet.
Abstract:
The invention is directed to a positive airway pressure (PAP) system with a head mounted harness assembly with a housing and a head position sensor located within or secured to the housing that detects the position of a patient's head, and communicates this head position information to a controller of the system which may be disposed within the housing having the position sensor or a second housing. The controller varies the output pressure of the pressure source, e.g. a rotary compressor, based, at least in part, on the head position information provided by the head position sensor. In a preferred embodiment, the position sensor is an accelerometer.
Abstract:
Die Erfindung betrifft ein Inhalationsgerät, bei welchem ein Arzneimittel zunächst verfestigt als Wirkstofftablette (7) vorliegt und mittels gesteuert einwirkender Aktoren eine Dosis des verfestigten Arzneimittels zu dispersen Pulverpartikeln mittels Abtragung von der verfestigten Arzneimitteloberfläche erzeugt wird. Bei einem Verfahren zum Betrieb des Inhalationsgerätes wird ausgehend von einem durch die Bedienperson des Inhalationsgerätes vorgegebenen Signal einem aktuatorischen Element eine definierte Energiemenge als Eingangsgröße zugeführt wird, die das aktuatorische Element in eine andersartige definierte Ausgangsgröße in Form von mechanischer Arbeit umsetzt. Zur dosierten Medikamentenabgabe werden verschiedene Formen von Wirkstofftabletten genannt.
