摘要:
A method of calibrating an analyte sensor in vivo, by providing a first predetermined stimulus to the sensor when the sensor is applied to a subject to produce a first sensor signal, measuring the first sensor signal, and determining a calibration function based on the first measured sensor signal resulting from the predetermined stimulus. The calibration function, when applied to further signals received from the sensor, can be used to provide a calibrated output.

The invention is directed to a device for delivering a pharmaceutically active compound or cosmetic substance to a subject comprises a flexible substrate sheet attached to an electronic controller. The controller is provided with a pair of electrical contacts on the underside thereof and is adhered to the sheet by means of a pair of strips of electrically conductive adhesive. The underside of the sheet is printed in two halves with electrically conductive ink to provide a pair of electrodes separated by an insulating barrier. A protuberance extends from each electrode and is folded onto the top of the sheet such that the contacts of the controller are adhered in electrical connection with the protuberances and thus also with the electrodes. The use of an adhesive to connect a controller in electrical communication with the electrodes enables an extremely simple construction of delivery device to be achieved.

An intradermal drug delivery device comprises a housing (301a, 301b) having a drug reservoir (312) therewithin and a gas generation chamber (313) separated from the reservoir (312) by a displaceable membrane (311). A microprocessor-controlled electrolytic cell (316a, 316b, 319) provides gas to expand the gas generation chamber (313) and thereby contract the reservoir (312). A hollow needle (310), communicating at an inner end thereof with the reservoir (312), extends from a lower surface (308) of the housing (301) such that contraction of the reservoir (312) forces drug to escape therefrom via the needle (310). The device permits delivery of drugs of relatively large molecular weights at slow controllable rates. A displaceable protective cover (303) is mounted in means (307) allowing movement of the cover (303) between extended and retracted positions (305, 306). The cover (303) has an adhesive lower surface (309) for attachment to the skin of a subject. In use, a release liner is removed, the device is pressed against the skin and the cover (303) snaps back to the retracted position (306), the needle (310) thereby piercing the skin. After use the housing (301) is pulled away and the cover (303) snaps to the extended position (306) before detaching from the skin, thus concealing the needle (310) before disposal.
摘要:
Oral drug delivery device having a housing with walls of water permeable material and having at least two chambers separated by a displaceable membrane. The first chamber receives drug and has an orifice through which the drug is expelled under pressure. The second chamber contains at least one of two spaced apart electrodes forming part of an electric circuit which is closed by the ingress of an aqueous ionic solution into the second chamber. When current flows through the circuit, gas is generated and acts on the displaceable membrane to compress the first chamber and expel the active ingredient through the orifice for progressive delivery to the gastrointestinal tract.
摘要:
A medicament delivery device has a reservoir within a housing and means for driving medicament from the reservoir. The device is provided with a filling mechanism upon which a medicament container sealed by a penetrable stopper is mounted. The mechanism comprises an internal bore which accommodates an internal rod from which a needle projects. Needle is hollow and is in communication with the reservoir. In order to fill the reservoir, the container is pressed into the bore, causing the needle to pierce the stopper, the stopper abutting against the rod and acting as a piston to drive medicament from the container as the container is pushed into the bore and moves relative to the stopper. Thus, the reservoir can be filled with the sterile medicament which is stable when stored in the container, and the filling is easily accomplished without the use of a syringe. A further advantageous feature is provided by a delivery needle which is mounted on the periphery of the lower surface of the housing. This configuration allows the driving means to be located adjacent to the skin, thereby, providing a more stable temperature and more predictable operation of the device.
摘要:
A liquid delivery device comprising a housing having a lower surface for application to the skin of a subject and having a reservoir and a gas generation chamber therein separated by a displaceable membrane. Gas generated by an electrolytic cell under the control of a microprocessor causes the gas generation chamber to expand and the reservoir to contract, thereby discharging a liquid drug, such as insulin, from the reservoir via a hollow delivery needle extending from the lower surface. The delivery needle and a sensor needle both extend from the lower surface a sufficient distance so as to penetrate through the epidermis and into the dermis when the housing is pressed against the skin. The sensor needle has an enzymatic coating for the detection of an analyte, such as glucose in the subject's plasma. The delivery needle is made of platinum-iridium, and a current passes between the needles and a potentiostat circuit according to the amount of glucose detected. A reference electrode (silver/silver chloride) which rests against the subject's skin increases the accuracy of the glucose measurement. The current through the potentiostat circuit is measured by a voltmeter and a signal from the voltmeter is amplified and communicated to the microprocessor which determines the correct rate of delivery of the drug on the basis of the level of analyte detected in the subject's plasma.
