Abstract: A medical instrument includes a sound card or an internal capability for generating sounds from a digital music or sound file. The medical instrument is one which generates unwanted noise and is constantly in the presence of a patient or an operator, and may be in a home, a clinic, a laboratory, or other intimate setting. For instance, a patient may be typically connected for hours to a hemodialysis machine that has a noisy pump. A blood-plasma volunteer may be hooked to a noisy blood separation machine for a period of time. A laboratory technician may work in close proximity to a sample preparation machine that constantly gurgles and whirrs. In each instance, a sound card and a speaker can generate previously-recorded masking noises that make the presence and operation of the machine more tolerable.

Abstract: The present invention lessens the amount of air entering between mating membranes of a pressure sensor. The pressure sensor of the present invention includes a transducer portion and separate patient or medical fluid transfer portion or dome. The transducer portion is reusable and the dome is disposable. The dome defines a fluid flow chamber that is bounded on one side by a dome membrane. Likewise, the transducer is mounted inside a housing, wherein the housing defines a surface that holds a transducer membrane. The two membranes mate when the dome is fitted onto the transducer housing. The pressure sensor enhances the seal between the mated membranes by creating higher localized contact stresses. The pressure sensor also reduces the amount of gas that permeates from the fluid chamber across the dome membrane and between the interface by making the dome membrane from a material having a low vapor transmission.

Abstract: Un instrumento médico incluye una tarjeta de sonido o una capacidad interna para generar sonidos a partir de un archivo de música digital o de sonido. El instrumento médico es uno que genera ruido no deseado y está constantemente en presencia de un paciente o un operador, y puede estar en casa, en una clínica, en un laboratorio, u otro establecimiento íntimo. Por ejemplo, un paciente típicamente puede ser conectado durante horas a una máquina de hemodiálisis que tenga una bomba ruidosa. Un voluntario de sangre-plasma puede ser unido a una máquina de separación de sangre ruidosa durante un período de tiempo. Un técnico de laboratorio puede trabajar muy cerca a una máquina de preparación de muestra que constantemente gorgotea y zumba. En cada caso, una tarjeta de sonido y una bocina pueden generar ruidos de enmascaramiento previamente grabados que hacen que la presencia y operación de la máquina sean más tolerables.
