medical instrumentation, relates to means for fastening optical devices on the head and can be used in all cases where precise and stable orientation of these devices relative to the head is required. The preferred area of study is the mounting of optical devices.

A ditch, for example, oculometers, when studying W and two halves of the frame are diluted around the Scientific Research Institute of eye movements or remote visual control devices when working with a large contingent of people, in particular, during mass examinations.

The aim of the invention is to improve the accuracy of measurements in mass studies by reducing the mobility of the nozzle relative to the head.

Fig. 1 shows a general view of the headpiece of Fig. 2, a device for fastening the transfer bridge.

The headpiece consists of a sliding frame formed by arcs 1-10 with a hinged joint 11, two multifunction locks 12.13, adjustable peripheral stops 20

hinge 11. When mounted on the head, the nozzle is pressed against the nose bridge with a central stop, and the stop, by turning in the sagittal plane around the screw 25, is in the position corresponding to the inclination of the nose of the person. Parts of the frame are tightened with locks 12,13. All peripheral stops 14-19 are adjusted until tight contact with the head is reached, after which the pro- istric adjustment of the optical device is effected.

Due to the fact that the portable support has an elastic body, its tighter fit to the nose bridge is possible, it is not necessary to leave the peripheral stops pressed on the threshold of pain, while moving 14-19 and the bracket 20 for strengthening the attachment on the head It reduces the number with the mechanism for fixing the portable one by 2–3 times for each coordinate of the rest stop 21. The handle 22 for controlling the comparison with the known technical mechanism for fixing the portable case and as a consequence increases the length of the frame. . To the accuracy of the measurements, the front of the frame is attached optical device 23.

The mechanism for fixing the transfer strap 21 may consist, for example, of a worm gear 24 with a thread in a central hole in which a screw 25 with a screw head 26 is placed, a shaft 27 with a handle 22 brought out to the top of the nozzle.

The portable support consists of reinforcement in the form of spring petals 28 and 29, rigidly connected to the base 30 with a plug 31 for connection to the fixation mechanism, and a body 32 of elastic material (rubber) enclosing the spring petals of the Armature Formula

Head attachment for mounting optical devices, containing a frame, adjustable peripheral stops, connected to the frame bracket with a removable portable stop with a saddle-like orthopedic surface, characterized in that, in order to improve measurement accuracy during mass studies by reducing mobility the nozzle relative to the head, the transfer stand 50 is provided with an internal elastic reinforcement, made of elastic material and installed with the possibility of rotation and fixation in the sagittal plane.

tours that form a concave orthopedic surface for contact with the nose.

Before installing the nozzle on the head from the kit of the bridge supports, select the stop most suitable for its support surface to the patient's nose bridge and set it with a fork 31 in the area between the bracket body 20 and the screw head 25 and lightly press the handle 22. reveal

When mounted on the head, the nozzle is pressed against the nose bridge with a central stop, and the stop, by turning in the sagittal plane around the screw 25, is in the position corresponding to the inclination of the nose of the person.

All peripheral stops 14-19 are adjusted until tight contact with the head is reached, after which the pro- istric adjustment of the optical device is effected.

Due to the fact that the pore-carrying pore has an elastic body, its tighter fit to the nose bridge is possible, it is not necessary to leave the peripheral stops pressed on the threshold of pain, while the mobility of the nozzle on the head decreases by 2--3 times along each coordinate comparison with the known technical solution and, as a result, the accuracy of the measurements
