Abstract
The present invention facilitates the detection of an occurrence of a physiological action imparting a displacement to a body part at a natural frequency signature by virtue of a bio-filter pad including a viscoelastic interior for intimate juxtapositioning against the body part, and having a mechanical resonance frequency midway in the range of the frequency signature associated with the physiological action.
Claims16
For use in the detection of an occurrence of a physiological action imparting a displacement to a body part at a natural frequency signature, a bio- filter pad comprising a viscoelastic interior for intimate juxtapositioning against the body part, and having a mechanical resonance frequency midway in the range of the frequency signature associated with the physiological action.
A method for detecting an occurrence of a physiological action imparting a displacement to a body part at a natural frequency signature, the method comprising the steps of
- (a) intimately juxtaposing a bio-filter pad against the body part, the bio-filter pad having a viscoelastic interior, and a mechanical resonance frequency midway in the range of the natural frequency signature associated with the physiological action;
- (b) intimately mechanically coupling at least one transducer against the topside of the bio-filter pad for generating electrical signals in response to displacements of the body part;
- and
- (c) processing the electrical signals for detecting occurrences of the physiological action.
Fetal activity monitoring apparatus comprising at least one transducer for intimate juxtaposition against an expectant mother's abdomen for generating electrical signals in response to her abdominal movements;
- and a fetal activity recorder for processing the electrical signals for detecting occurrences of fetal activity,
- characterized in that the apparatus has an electrical signal amplification of about 45±5 dB.
