摘要:
vein viewer system for mobile devices. The practice of peripheral venipuncture requires specific skills related to characteristic limitations of the structures that make up human skin, such as the caliber of veins, fat layers, and the patient's clinical condition. Although the medical imaging device market provides infrared light-spectrum photography-based vein viewers, characterized by greater penetration into organic structures, the high cost of such an apparatus is an impediment to the spread of this technology. The invention presented herein is a vein viewer system defined by a sampling device specifically designed to obtain vein images from their interaction with short infrared wavelengths. It is integrable with conventional mobile devices via cable connection and an auxiliary application that processes and displays subcutaneous vein images on the smartphone or tablet screen in real time. The sampler lighting system provides two wavelengths, 760nm and 850nm, alternately activated by selector switch and attenuated by a potentiometer. Attachment of the sampling device to the body of the conventional mobile device is accomplished by means of an adjustable base, which can be tilted to provide perpendicular sampling to the mobile device screen, as well as connected to a flexible rod to support the complete system, freeing the hands. of user.sistema visualizador de veias para dispositivos móveis. a prática da punção venosa periférica requer habilidades específicas relacionadas a limitações características das estruturas que formam a pele humana, como o calibre de veias, camadas de gordura e condições clínicas do paciente. embora o mercado de dispositivos de imagens médicas forneça visualizadores de veias baseados em fotografia do espectro de luz infravermelho, caracterizado por uma penetração maior em estruturas orgânicas, o custo elevado de tal aparelho é um impeditivo para a disseminação desta tecnologia. o invento apresentado neste documento é um sistema visualiza
