Abstract:
This invention relates to a doser comprising a syringe (2) with a needle (3) which extends beyond the doser (1), which comprises an engagement face (4) in the vicinity of the needle so that the engagement face rests against the surface of the tissue into which the needle is inserted. Detector means (5) are provided on said engagement face to sample signals on the skin of the patient. The invention further provides means (13) for receiving external information related to health monitoring of a patient. This provides a doser that may record heart rate, EKG, BGM and hypo-alarm administered medicine. The doser may further be arranged to calculate an appropriate dose of medication on the basis of a number of acquired inputs.
Abstract:
At least one electric discharge lamp capable of generating a broadband output pulse of a range of wavelengths in the visible spectrum, the output pulse having a predetermined time interval and a predetermined total electrical energy input for the pulse, has a drive circuit for delivering energy pulses to the electrical discharge lamp, as well as a sensor for sensing an optical output from the discharge lamp; and a control mechanism for operating the drive circuit in response to variations in optical output detected by the sensor.
Abstract:
A flashlamp drive circuit including a storage capacitor which is charged and selectively discharged in order to drive a flashlamp. A capacitor (116) is connected in parallel with each respective flashlamp (106) in a bank of flashlamps. Each capacitor (116) has a comparatively small capacitance so as to be capable of storing only a portion of the total energy pulse required to be delivered to the respective flashlamp (106). A controller, comprising a digital signal processor (118) and a microprocessor (120) is provided to control the operation of all of the flashlamps (106) in the bank via respective switch mechanisms (110). In use, each energy (or drive) pulse delivered to a flashlamp (106) is comprised of a plurality of smaller energy packets resulting from repeated charging and discharging of the respective capacitor (116). Thus, the shape and duration of the current pulses delivered to the flashlamp (106) is highly controllable and the size of the storage capacitor (116) required is significantly reduced relative to the prior art.
Abstract:
The apparatus comprises a) a set of probes each having tips arranged to simultaneously touch the skin and define a predetermined pattern on the skin, at least one of the probes being arranged to transmit a pulsed electrical signal and at least one of the probes (which me be the same as or different to the transmitter probe) being arranged to receive the transmitted electrical signal; b) a signal detector for detecting the or each received electrical signal; c) means for comparing a numerical value obtained from at least one detected signal from the signal detector with at least one predetermined numerical value; and d) means for providing an output when said value obtained from the detected signal differs from the predetermined numerical value by more than a predetermined amount. The apparatus is used to control intense pulsed light devices used for local treatment of various skin conditions and to influence non-desired hair growth.
Abstract:
A device for the treatment of skin by radiation pulses. The device has a detector measuring a biophysical property of skin, such as temperature increase, dispersion or absorption coefficient, or reflection coefficient for light having a predetermined wavelength, and also has a control unit which determines, from the biophysical property, a safe dose of radiation. The device automatically protects against an overdose from the radiation source.The invention can be used, not only in a hair removing device such as a laser epilator, a laser shaver or a flashlight epilator, but also in devices for the medical treatment of skin by means of radiation, such as photodermatology systems.
Abstract:
The apparatus for monitoring muscle contractions of a subject (for example as a check on epilepsy or Parkinson's disease) comprises: a first sensor arranged to be placed on a reference location on the body of a subject for sensing, over a prolonged period of time, a reference parameter derived from at least one of movement and electrical activity of the muscles of the body at the reference location; at least one further sensor arranged to be placed on a chosen location on a limb of a subject, for sensing, over a prolonged period of time, a monitoring parameter derived from at least one of movement and electrical activity of the muscles of the limb at the chosen location; comparison means for comparing the monitoring parameter with the reference parameter; and output means for producing an output by comparison of the monitoring parameter and the reference parameter, the output comprising either recorded data which provide a record of an epileptic event in the prolonged period of time or an alarm output after the prolonged period of time when the monitoring parameter is outside a predetermined range compared to the reference parameter.

Abstract:
This invention relates to an system for self treatment. The system consists of several portable modules where one of the modules is designated as a master module. The master module controls, supervises and monitors all the mutual information and data exchange between itself and the rest of the modules. The modules can e.g. consist of a BGM, a doser and a storage container. The modules may be able to generate and store data which is transmitted to the master module if it is within range. If the master module is not within range, the data is kept locally in the module until the master module is available. The master module can send the data to an external unit like a computer or database for further processing. A physician or an expert care-team can access the data in the database and give guidance to the patient on the basis of these processed data. This processing could also be done automatically by utilization of an expert system.
Abstract:
The apparatus is arranged to supply a flow of substantially pure oxygen to a person, and comprises a source of substantially pure oxygen gas, means for release of the substantially pure oxygen gas from the source into an ambient atmosphere; and means for cooling the substantially pure oxygen gas released from the source to a temperature below that of the ambient atmosphere. The substantially pure oxygen gas when cooled by the cooling means can be allowed to sink under ambient pressure by convection into a zone including the ambient atmosphere, the zone being beneath, and in convective communication with, the cooled substantially pure oxygen gas, whereby the cooled and sunken substantially pure oxygen gas can come into contact with the skin of a person in that zone. At least one parameter (such as temperature, oxygen concentration, sound or vibration) is monitored in the zone and operation of the release means is only permitted when the parameter is in a predetermined range.
