Sobre la forma de garantizar la trazabilidad metrológica en los sistemas hospitalarios

Resumo

Within the equipment that exist in the hospitals, there are very diverse performances for the correct operation of the equipment that is intended both to measure on the patient or for treatment on these same, the range of equipment available is very large, without which directly are installed or, more correctly, are implanted in the patient. The hospitals have established patterns of maintenance both corrective and preventive, also of verification of security and, in some cases, actions which are intended to check the magnitudes in the equipment. This last is not normal, in fact, in many cases, the majority, it is not known as to be able to check that the magnitudes of a computer can be traced to a pattern of national measure. The research has been developed to determine, is something that this patent up to the International Organization for Standardization (ISO), that do not exist for many teams established principles to ensure the metrological traceability gives the physical quantities in which they work during its useful life. Due to the breadth of this field, the development of research has been conducted in a pyramid format, from the needs to be able to reach a specific study of specific equipment (Clinical Thermometers, Tensiometers, Ultrasound, and Short Wave). To reach theme, has been carried out a study of how is the metrological traceability across the entire spectrum, from the management to individuals cases. Considering the large amount of existing documentation and arriving to determine the labor camp in the metrology hospital, sorting equipment and determining how are defined the methods that lead to reality the metrological traceability, in the standardization. A group not too worked for medical electrical equipment are found within the rehabilitation treatment of traumatology, being equipment of very common use in the health centers for muscle injuries and bone. In this matter has been dedicated an extra effort, with a report history of its origin and where they are now. We have studied within these teams about the treatment of ultrasound, diathermy, short wave, which are the most representative of the equipment that is destined to electro therapy, but it must be borne in mind that there are fields that have been mentioned globally of rehabilitation, as are the therapy or the biomechanics, similar to other health technologies from other specialties (radiology or clinical analysis). There is, also, within the therapy, all these treatments own gym, such as pulleys, weights, tables of massages, balls, etc… that its metrology is simple, are computers that there are means of verification of the magnitudes that used by the existence in other activities of the industry (scales, weights, etc). The research carried out has tried to assess the entire global and reach specific cases to determine the situation as it is. Arriving in the development of a classification of equipment and standards, which give us a glimpse of the metrological needs and establish a Management of the Metrological Traceability, concluding in the study for computers that have been mentioned.
