Abstract: The invention relates to a process of treatment in the field of dermatology, for the treatment of cutaneous angio dysplasias, using the energy emitted by a laser source, as well as to an apparatus for the treatment of skin angiomas implementing the process. The apparatus includes a laser source suitable for supplying laser radiation, a treatment instrument for receiving the laser radiation from the source and whereby a plurality of consecutive laser shots is effected to form a plurality of resulting impacts on the area of the body to be treated. Following each shot, the area of the body thus treated has, at the resulting impact, at least a given relaxation time. The apparatus includes a support frame, an optical fiber disposed in the frame. The optical fiber has two ends, the first of the ends being suitable for connection to the laser source via the connecting means, the second end being mobile and suitable for generating a displaceable laser spot.

Abstract: This invention relates to a cupola-type visual stimulation ophthalmological pparatus for examining the visual field of a patient and performing electrophysiological examinations. It comprises a projection screen consisting of the inner surface of a hemispherical cupola, the patient's eye being disposed centrally of the cupola during the examination. A device for projecting visual stimuli on the screen is provided in the upper portion of the cupola and comprises essentially a casing incorporating a light source, filter means, an object mask, a lens and a movable reflecting mirror located in the vicinity of the cupola center. This mirror is adapted to project toward any desired point of the screen a luminous stimulus perceived by the patient for measuring the extent of the patient's visual field. Moreover, with the projection device it is possible to illuminate the complete visual field according to criteria relating specifically to electrophysiological examinations.

Abstract: Apparatus for cutting a tube of semi-rigid material at a predetermined point to make possible separate removal of the contents of the tube on either side of the cutting point comprises a flat blade and jaws which together define a longitudinal channel suitable for receiving and gripping the tube for the greater part of its periphery. The jaws are provided with a slit which intersects the channel transversely over the whole of its cross-sectional periphery. Additionally means for relatively moving the blade and jaws are provided so that the blade penetrates the slit and its cutting edge passes transversely through the channel, thus cutting the tube, until the blade covers the section of the channel level with the slit, and provides a seal to both parts of the tube after cutting.
