Adhesive patch having multiple acoustic sensors for monitoring acoustic signals

摘要

An adhesive patch for monitoring acoustic signals from a human or animal body, comprising a skin contact surface, converting means for recording both body acoustic signals and environmental acoustic noise, reducing the body signals by the recorded noise, and providing a first electric output signal. The patch also comprising an adhesive element and a compression structure for attaching the converting means to the skin surface. The patch further comprises transmitting means for transmitting the output signal to a peripheral device.

主权项

1. An adhesive patch for monitoring acoustic signals from a human or animal body comprising:
an adhesive part and a converting part being releasably connected to each other whereby each may be separated from the other so that one may be discarded and the other reused; wherein the adhesive part is provided with an adhesive surface adapted for providing a skin contacting surface, and the adhesive part has a through-going opening whereby communication through the adhesive part to the skin contacting surface is provided; and the converting part comprises a converting means comprising:
a first microphone having a skin contacting surface, the first microphone configured to record body acoustic signals and convert them to body output signals;a second microphone mounted to record environmental noise from an environment surrounding the adhesive patch and converting the recorded noise to a noise output signal; anda controller unit that is configured to receive the body output signals, remove any environment noise from the body output signals by processing the body output signals with the noise output signal to form a controller output signal, and transmit the controller output signal to a peripheral device; wherein when the converting part is connected to the adhesive part, the converting means is arranged in the opening of the adhesive part such that the skin contacting surface of the first microphone and the skin contacting surface of the adhesive part both come into contact with a skin surface as the adhesive patch is attached to a skin surface of a user, and wherein the adhesive part is also provided with a compression structure at the skin contacting surface of the adhesive part, wherein the compression structure is in the form of at least one protrusion that projects out from the skin contacting surface and is positioned around the first microphone.
