Abstract

Un sistema de detecci?n de desconexi?n de acceso ac?stico es ?til para detectar cuando se descarga una aguja de acceso o cuando se filtra la sangre. El sistema de detecci?n de desconexi?n ac?stico incluye un transmisor ac?stico (18) y uno o m?s sensores ac?sticos (19a, 19b) colocados ascendentes de un sitio de acceso de un paciente, los sensores adecuados para generar y detectar una se?al ac?stica que se pretende pasar sin obstrucci?n a trav?s del sitio de acceso. El transmisor ac?stico puede colocarse en una m?quina de terapia (10) para generar una se?al ac?stica. El sensor ac?stico est? montado corriente abajo del transmisor, tal como en la m?quina de terapia en donde se bombea sangre hacia o se regresa desde el paciente, en el paciente, o en la m?quina de terapia en donde ingresa sangre a la m?quina de terapia. La m?quina de terapia, tal como una m?quina de di?lisis, puede programarse para no iniciar o continuar la operaci?n a menos que la se?al ac?stica est? dentro de ciertos par?metros.
