Abstract

TONÈMETRO DE ACHATAMENTO. Tonómetro (10) para determinar a pressão intra-ocular tendo um corpo, que pode ser transparente e essencialmente tubular (12). Um êmbolo (28) está localizado dentro do corpo de uma mola helicoidal (36) atua entre o corpo e o êmbolo. Um elemento marcador (24) é retido friccionalmente dentro do corpo e é deslocado em relação à escala externa (20) no corpo. Quando em uso, o tonómetro é trazido contra a pálpebra (50) de um olho fechado e o corpo deslocado em relação ao cabeçote do êmbolo até que a pressão seja suficiente para criar um fosfeno de pressão. O meio é então removido e o deslocamento do elemento marcador, indicativo da pressão aplicada, é lido. Esta leitura corresponde à pressão intra-ocular. O dispositivo pode incluir um elemento de retorno (49) para trazer o elemento marcador de volta à posição zero ou posição de repouso.
