摘要：
The present invention relates to an electronic biomedical dynamometer capable of measuring grip forces and variant forces over time in patients ranging from 5 n to 1400 n of any age between 6 to 78 years and presenting various types of injuries. points on the fingers of each hand. The dynamometer regardless of the physical capacity of the patient has the same sensitivity, without causing any damage to its mechanical structure. The dynamometer has a mechanical structure consisting of two cylindrical rods (1) with threads (6) to allow two doors (3) to be inserted in its upper part (3) which are rotated on the rods to the desired position to fix the upper support (4), dynamometric ring (5) where a metal extensometer bridge is glued and the upper finger support (2) which is fixed to the upper support (4) by means of a screw (11). This assembly is joined by the metal wire (10) and fixed to the two nuts (3). the upper nuts (13) act as lock nuts to lock and immobilize the mechanical assembly. the upper support (2), the upper support (4) and the torque ring (5) can be made of various materials, such as metal, polymer, plastic and others. The application of forces by the fingers on the upper support (2) causes the traction on the metal wire (10) and consequently the elongation of the electrically responsive torque ring. The dynamometric ring (5) has several metal blades (12) containing different thicknesses that are used considering their age or equivalent physical capacity of the patient. the dynamometer has a compact signal conditioning circuit that modulates, amplifies, filters and produces a dc signal from a peak detector, a data acquisition board that converts the analog signal from the signal conditioning circuit to digital signal, a computer interface for plotting graphs over time, indicating maximum points, minimum points, inflection points, and recording information performed with each patient.a presente invenção refere-se a um dinamômetro biomédico eletrônico capaz
