摘要:
Apparatus is described for use with (a) a muscle of a subject's body and (b) an implanted functional device in the subject's body. An electrode is coupled to the muscle. A stimulator causes the muscle to undergo movement by driving a current into the muscle, via the electrode. An energy assembly including a flywheel and an energy converter, stores energy associated with the movement of the muscle. The energy assembly powers the stimulator and powers the implanted functional device, based on the movement of the muscle. Other embodiments are also described.
摘要:
A device is provided for treating skin on the body of a subject. The device includes a plurality of electrodes, which are adapted to be placed in contact with the skin and then moved across the skin while maintaining electrical contact with the skin. The device additionally includes a power source, which is adapted to apply a current between two or more of the plurality of electrodes at the same time as the electrodes are being moved across the skin.

摘要:
A device for facilitating transdermal passage of a substance through skin on the body of a subject is provided. The device preferably includes afcn electrode and a control unit. In a preferred embodiment, the control unit is adapted to drive the electrode to apply to the skin a current capable of ablating stratum corneum epidermidis of the skin, so as to facilitate transdermal passage of the substance. The control unit detects generation of at least one spark responsive to application of the current, and modifies a parameter of the current responsive to detecting the generation of the at least one spark.

Devices for facilitating transdermal passage of materials are provided. In a preferred embodiment, a device for delivering a substance to skin of a subject is provided. A substance storage unit is adapted to store the substance. An analysis unit is adapted to receive a portion of a body fluid of the subject, to analyze the portion, and to generate a signal responsive to the analysis of the portion. One or more electrodes are adapted to be placed at respective sites on the skin. A substance delivery unit is adapted to receive the signal, and, responsive thereto, to drive at least some of the one or more electrodes to apply to respective ones of the sites on the skin a current capable of ablating stratum corneum epidermidis of the skin, so as to facilitate delivery of the substance from the storage unit through the skin at the respective ones of the sites.
摘要:
An inhaler device for administration of a dry powder to a patient includes a package containing a dose of the dry powder and a magnetic field generator, which produces a magnetic field in a vicinity of the package. The magnetic field causes motion of particles of the powder so as to deaggregate the powder in the package, whereby the powder is inhaled by the patient. Preferably, the package includes walls made of a flexible material, which vibrate under the influence of the magnetic field so as to impart the motion to the particles.
摘要:
A method and device for plucking hair by engaging the hair with a hair-plucker body to clamp the hair thereto, moving the hair-plucker body and the hair clamp thereto in the plucking direction with respect to the skin, and successively interrupting the movement of the hair-plucker body and the hair clamp thereto such that the hair-plucker body applies a series of short tugs to the hair until it is plucked from the skin.
摘要:
An ultrasonic nebulizer includes a supply container for the liquid to be nebulized, and an electrolytic cell having electrodes for generating a gas according to the amount of electricity conducted through the electrodes. The generated gas is effective to control the pressure in, or volume of, the supply container, and thereby the feed of the liquid therefrom to the ultrasonic nebulizer nozzle.
摘要:
A gamma-ray camera is described including a collimator receiving and collimating the gamma rays, a converter matrix converting the gamma rays to electrons, an electron-image multiplier receiving the electrons and producing a multiplied electron output, and means for reading out the output of the electron-image multiplier.A converter matrix is described for converting gamma-rays to electrons comprising a metal plate emitting electrons upon being impinged by gamma-photons, the metal plate having a face formed with a plurality of spaced parallel surfaces which extend substantially parallel to the direction of the gamma-rays. Also described is a converter matrix of scintillation crystals, one face of each crystal including a photo-sensitive coating, the opposite face of each crystal being clear, the remaining faces of each crystal being coated with a light-reflecting coating.
摘要:
A device for ablating the stratum corneum epidermidis of a subject, including a plurality of electrodes, which are applied to the subject's skin at respective points. A power source applies electrical energy between two or more of the plurality of electrodes, in order to cause ablation of the stratum corneum primarily in an area intermediate the respective points.
