Abstract

This invention is a stethoscope for use by a veterinary surgeon with a microphone transducer (15) mounted within a casing arranged to be held by a harness against the skin of the animal, with the transducer opening coupled to the skin through an enclosed column of air, and the harness held in position by a grid (33, 34) capable of being attached to the animal'"'"'s hair. The output from the transducer can be transmitted from the animal by radio.

Claims

1. A stethoscope for use on a horse, comprising a casing, a transducer in said casing, and a harness adapted for attaching to an animal having a mane, said harness including a strap having a pocket in which said transducer and its casing is held, and including a perforated grid structure attached to said strap, said perforated grid structure adapted for being intertwined with the mane of said horse, the pocket being displaced from the grid structure so that said transducer is held against the windpipe of said horse when said grid structure is intertwined with said mane.

2. The stethoscope of claim 1 wherein said perforated grid structure comprises a plurality of bars separated by elongate apertures, said bars including elongate wedge shaped strips of resilient material, wherein said mane is intertwined through said apertures and around said bars, and is held by said bars and said strips.

3. A stethoscope as claimed in claim 1 comprising a radio transmitter for mounting on one of the animal and harness, and connected to receive an input from the transducer.

4. A stethoscope as claimed in claim 1 in which the transducer is in a housing having sound attentuating material encasing the transducer.

5. A stethoscope as claimed in claim 4 including slack electrical conductors from the transducer to an outlet connection, the conductors being embedded in the attentuating material.

6. A stethoscope as claimed in claim 4 in which the housing is resiliently mounted within the casing so that when the casing is located against the animal a transducer aperture is against the skin of the animal whereby the transducer is coupled to the skin of the animal by an enclosed column of air.

7. A stethoscope as claimed in claim 4 including a pad with adhesive on opposed faced on that part of the casing to be presented to the skin of the animal.
