摘要：
Electronic biomedical dynamometer with metalon structure for measurement, analysis and recording of grip strength information. The present invention relates to an electronic biomedical dynamometer capable of measuring grip forces and time varying forces of patients in the range of 5n to 1000n of any age and presenting various types of injuries to 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. In addition, the dynamometer has a metalon mechanical structure consisting of the external support (1) and the internal support (2). The external support (1) is fixed to the external support (7) to the palm using the fixing screw (10). The internal support (2) is secured by means of a similar screw (10) to the internal support (6) for the fingers. This inner support (2) moves through the outer support (1) by means of rails (8) at its top and bottom. the inner support (2) is chain connected (5) to the torque ring (3). In the dynamometric ring (3) is placed a bridge of metal extensometers whose purpose is to respond electrically to the deformation suffered by the application of force by the fingers on the internal support (6). The extensometer bridge response is connected to the signal conditioning circuit which amplifies, filters, modulates and generates a dc signal by means of a peak detector. This dc analog signal is connected to a data acquisition board which converts it into a digital signal. This digital signal is sent to the computer interface on the notebook for the application of forces and analysis of the plotted graphs. Patient information and graph responses are recorded to allow you to track patient exams over time.dinamômetro biomédico eletrônico com estrutura de metalon para medição, análise e registro de informações da força de preensão . a presente invenção refere-se a um dinamômetro biomédico eletrônico capaz de medir forças de preensão
