摘要:
A metered dose inhaler for administration a liquid phase medium using a rotating metering element that transports the metered dose from the pressurized canister to the mouthpiece. The metering is improved in that there is an efficient protection against penetration of outside air, and in that the counting of the doses is improved by preventing backwards rotation of the rotating metering element.
摘要:
The present invention relates to a device to be used with a medical administration device, which administration device comprises administration drive means for administrating a prescribed dose of medicament; mechanical dose setting means for setting a prescribed dose of medicament to be administered, including a mechanical indicating member (76) fixedly connected to said administration drive means (84) for indicating the prescribed set dose, wherein said device comprises mechanical dose information means for registering the prescribed dose of medicament to be administered including a mechanical information member adjustable to display that said prescribed dose to be administered is correct, and inter-connected to said mechanical indicating member such that when the prescribed dose is set, this is indicated positively by indications on said mechanical information member.
摘要:
Injection device comprising a tubular elongated main body, a needle shield slidably arranged in said main body, a needle shield link slidably connected to said needle shield, a enclosure containing medicament arranged in said main body, a needle connected to said enclosure, a plunger operatively arranged to said enclosure for ejecting said medicament through said needle and arranged on its upper part with a number of outwardly extending stop members, spring means arranged to said plunger for operating said plunger, a dose activating means, a needle shield spring surrounding the needle shield link. The invention is characterised in that said injection device further comprises a first tubular member rotationally and slidably arranged inside said needle shield link, said tubular member comprises a number or ridges and protrusions on both its outer and inner surfaces, said ridges and protrusions on the outer surface of the tubular member co-operate with guide members arranged on the inner surface of said needle shield link, said ridges and protrusions on the inner surface of the tubular member co-operate with the outwardly extending stop members of the plunger that said injection device further comprises a second tubular member arranged inside said housing, arranged and designed with a number of ridges and protrusions on its inner and outer surfaces capable of setting and delivering a certain preset dose.
摘要:
A dose selective breath actuated inhaler including a meterless canister storing a pressurized medicament, and a vacuum actuated release, where application of a vacuum to the inhaler initiates a release of the medicament in the canister. The inhaler includes a mechanism for dialing a proper dose of pressurized medicament, a computer for generating a plurality of signals including a solenoid trigger signal, and a solenoid which upon receipt of a solenoid trigger signal actuates a solenoid arm to end the release of the medicament from the canister.
摘要:
The need for the delivery of insulin by injection can be reduced or eliminated by delivering an aerosolized monomeric insulin formulation. Repeatability of dosing and more particularly the repeatability of the blood concentration versus time profile is improved relative to regular insulin. The blood concentration versus time profile is substantially unaffected by specific aspects of the patient's breathing maneuver at delivery. Further, the rate at which blood glucose is lowered is increased by the use of monomeric insulin. Particles of insulin and in particular monomeric insulin delivered to the surface of lung tissue will be absorbed into the circulatory system. The monomeric insulin may be a dry powder but is preferably in a liquid formulation delivered to the patient from a hand-held, self-contained device which automatically releases an aerosolized burst of formulation. The device includes a sensor which is preferably electronic which measures inspiratory flow and volume which measurement can be used to control the point of drug release.

摘要:
A nebulizer comprising an aerosol generator and a titration mechanism comprising a dosing mechanism, a screw assembly, a plunger and an actuator, wherein the dosing mechanism is rotatably mounted in the nebulizer and the plunger is mounted in the nebulizer to travel along a longitudinal axis substantially perpendicular to the plane of rotation of the dosing mechanism. The actuator is mounted to the nebulizer to travel in the direction of the longitudinal axis. The screw mechanism allows the rotation of the dosing mechanism to fix a variable distance of travel of the plunger based on the selected dose, without moving the plunger longitudinally. This allows the user to verify and if necessary correct the selected dose prior to any drug being released from the vial. Operation of the actuator causes longitudinal movement, through the screw mechanism, to the plunger. The actuator always moves a fixed distance along the longitudinal axis, while the plunger always moves a variable distance depending on rotation of the dosing mechanism to a selected dose.

A liquid medication cartridge includes an accommodating portion for accommodating a liquid medication; a liquid discharge portion having a discharge port for discharging the liquid medication by using an ink jet technique, a communicating member for establishing communication between the accommodating portion and the liquid discharge portion and a filling member for filling the liquid discharge portion with the liquid medication.
摘要:
A cartridge for powdered pharmaceuticals. At least two storage spaces are provided which are separate from each other and which are each intended to hold a multiplicity of doses of a medically active substance. The storage spaces are individual cartridges which may be lockingly coupled together to form a single cartridge. Each individual cartridge has a metering cavity.
