FIELD: medicine. ^ SUBSTANCE: invention refers to dermatology. Device for testing human skin vessels reactivity and quantitative evaluation of dermographism consists of frame, which in corporates supporting element capable of moving and attaching thereto removable dermographic heads with corresponding surfaces contacting with patient's skin, as well as scale and resistive element with the function to exert resistance to movement of supporting element in frame. Frame is made in the form of thin-walled lengthwise elongated hollow element, with a scale made an its outer surface along its length. Inside there is supportive element in the form of hollow pin, whose cavity incorporates resistive element fixed with one end inside shift and with the other end to the device frame wall. Index arrow located opposite the scale of pressure indication is fixed on the aforesaid pin, with removable dermographic heads are made to be fixed to the end of the hollow pin protruding from the frame. ^ EFFECT: increased accuracy and reliability of results of human skin vessels reactivity tests and quantitative evaluation of dermographism. ^ 6 cl, 1 dwg, 1 tbl |
