Abstract

Adapters and methods for reversibly converting a standard stethoscope to a multimedia and/or telemedicine ready stethoscope. The adapter includes a housing having a conduit for conducting sound therethrough, a first coupler for coupling the housing to the transducer of a standard stethoscope, a second coupler for coupling the housing to the sound conduction hose of a standard stethoscope, and a second transducer for converting an audible tone to an electronic signal.

Claims

1. An adapter for standard stethoscopes having a stethoscope transducer for picking up a sound signal connected to an earpiece for receiving the sound signal by a flexible hose for guiding the sound signal from the stethoscope transducer to the earpiece, said adapter being for reversibly converting standard stethoscopes to multimedia and telemedicine ready stethoscopes without significantly altering the look, feel, or performance of the standard stethoscopes comprising:

(a) a housing having means for conducting sound therethrough from the stethoscope transducer through the hose to the earpiece;

(b) means for coupling the housing to the stethoscope between the stethoscope transducer and the earpiece;

(c) a second transducer in the housing for converting a sound signal from the first said stethoscope transducer to an electronic signal without interfering with the conduction of the sound signal from the first transducer to the earpiece, and wherein

the coupling means is adapted to reversibly couple the housing to the first transducer and the hose leading to the earpiece of a standard stethoscopes, wherein;

the housing is a branched member having a first branch and a second branch;

the first branch is formed to define a conduit therethrough between said first transducer and the earpiece;

the second branch is formed to define a chamber; and

the chamber is in communication with the conduit,

wherein the means for coupling the housing to the stethoscope comprises;

means for directly and physically coupling the housing to the stethoscope transducer; and

means for directly and structurally coupling the housing to the hose leading to the earpiece,

the means for coupling the housing to the stethoscope transducer is a first coupler; and

the means for coupling the housing to the hose is a second coupler,

wherein the first coupler is a female coupler and the second coupler is a male coupler, wherein;

the female coupler has a receiving end and a conduit therethrough; and

the conduit is lined with compressible material.

2. The adapter of claim 1, wherein at least one of the couplers is a bifurcated coupler.

3. The adapter of claim 1, wherein the couplers are removably coupled to the housing.

4. The adapter of claim 2, wherein the couplers are removably coupled to the housing.

5. The adapter of claim 1, wherein the second transducer is housed in the chamber.

6. The adapter of claim 1, wherein the second transducer is a microphone capable of generating an electronic signal compatible with standard analog and digital recording devices.

7. The adapter of claim 6, wherein the microphone is capable of generating an RF-11 signal.

8. The adapter of claim 1 wherein:

the female coupler has a receiving end and a conduit therethrough;

the conduit is lined with a compressible material;

the couplers are removably coupled to the housing;

the second transducer is housed in the chamber;

the second transducer is a microphone capable of generating an electronic signal compatible with standard analog and digital recording devices; and

the microphone is capable of generating an RF-11 signal.
