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.

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: 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.

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.
