摘要:
A pressurised metered dose inhaler (1) comprising: a reservoir (2) for containing pressurised product, a valve (9) having an inlet (11) communicating with the reservoir and an outlet (14) through which product is dispensed in use, a piece of magnetisable material (5), an armature (8) extending into proximity with the valve, and an electromagnet (7) surrounding at least a portion of the armature. Wherein the armature is coupled to, or forms part of, the valve such that controlled energisation of the electromagnet causes the armature to be either attracted to or repelled from the piece of magnetisable material one or more times to operate the valve for a controlled time period to effect dispensation of a metered dose of pressurised product from the reservoir through the valve outlet.
摘要:
The need for the delivery of insulin by injection can be reduced or eliminated by delivering aerosolized insulin. Repeatability of dosing is obtainable by using either regular insulin or monomeric insulin. When delivering insulin (not monomeric) by inhalation, the total inhaled volume should be about the same at each delivery to obtain repeatable results. The patient can be coached (by teaching) to inhale a given amount of air and can also be coached (by teaching) to inhale at a given flow rate. Further, the rate at which blood glucose is lowered is increased by the use of monomeric insulin. Particles of insulin and monomeric insulin delivered to the surface of lung tissue will be absorbed into the circulatory system. A dry powder or a liquid insulin formulation is delivered to the patient from a mechanical or electronic hand-held, self-contained device.
摘要:
A method and system is disclosed which is capable of delivering at a high dose rate, respirable solid aerosols derived from aqueous- or nonaqueous-based solutions containing the desired therapeutic agent(s). The method and system comprises the integration of an aerosol generator, an aerosol evaporator, an aerosol concentrator, and an aerosol flow regulator. The aerosol generator generates 10-30 μm droplets, with a narrow size distribution. The aerosol jet is arrested by a coaxial counter-flow heated air jet, and evaporated rapidly by annular swirling heated air. Most of the air, together with the unwanted solvent vapor, is removed from the aerosol stream during the process of aerosol concentration. The output aerosol carries the dry particles to be inhaled by the patient. The respiratory-governed control of aerosol fluid generation system delivers fluid containing the test agent of interest (drug or toxin) to the aerosol generator throughout inhalation.
摘要:
Bioactive agents are topically administered or delivered to a mucous membrane by a jet dispenser using inkjet technology, such as that used in printing. The dispenser propels precise volumes of droplets or powder for administration to a subject, such as being inhaled through the mouth or nose. A controller in the dispenser may control delivery of multiple different drugs, timing of drug administration, or change drug regimens in response to a changing medical condition of a patient, such as those monitored by a sensor in communication with the controller, for example to prevent an overdose. Administration methods are also provided, along with replacement kits.
摘要:
A medicament dispenser for use in the storage, presentation and/or dispensing of medicament comprising a body shaped for receipt of a medicament container. In association with the body, there is a first transceiver for transmitting and receiving data. A medicament container is receivable by the body. In association with the medicament container, there is a second transceiver for transmitting and receiving data. Data is transferable in two-way fashion from the first transceiver to the second transceiver. The medicament dispenser may be supplied in kit of parts form.
摘要:
There is provided a medicament dispenser device comprising a housing including a dispensing outlet for insertion into a body cavity; a medicament discharge device moveably housed within the housing, the medicament discharge device comprising a medicament container for storing the medicament to be dispensed and a medicament dispensing mechanism for dispensing medicament from the container to the outlet; a user operable actuator moveable with respect to the medicament discharge device to apply an actuating force to the dispensing mechanism; and an actuation indicator responsive to application of the actuating force. A pre-load means is provided to the user operable actuator to prevent application of the actuating force to the dispensing mechanism and actuation indicator until a pre-determined threshold force is applied to the user operable actuator.
摘要:
A medical dispenser being adapted to hold a number of medical doses and being adapted to determine when a user or patient gains access to one or more of the medical doses, the dispenser comprising: means for determining each of a first plurality of points in time or time intervals at which the user or patient should take a medical dose, means for detecting each of a second plurality of points in time where the user or patient gained access to the medical doses, means for providing to the user or patient information relating to a relation between the first and second pluralities, and wherein the providing means are adapted to, if the user gains access to the medication multiple times per point in time or time interval in the first plurality of points in time or time intervals, provide information relating to a relation between the pairs of one of the firs plurality of points in time or time intervals and a first of the second plurality of points in time occurring after the pertaining point in time of the first plurality or within time interval of the first plurality.
摘要:
An aerosol generating device generates an aerosol having a desired particle size by passing a liquid through a flow passage heated to convert the liquid into a vapor. The flow passage includes an outlet section that controls the exit velocity of the vapor and produces an aerosol with a desired particle size. The aerosol generator can be incorporated in a hand held inhaler, and the liquid can include a medicament, which is delivered to a targeted portion of the lung using the inhaler.
摘要:
A counter for indicating the number of doses left in a canister that is suitable for use in a metered dose inhaler. The counter is affixed to the canister and includes a module for providing an indication of the number of doses left in the canister and a triggering mechanism for updating the indication in response to activation of the inhaler.
摘要:
Devices for the controlled release of one or more drugs are provided. The devices include an implantable stent, at least two reservoirs in the stent, and a release system contained in each of the at least two reservoirs, wherein the release system comprises one or more drugs for release.
