Abstract

A patient'"'"'s discomfort from a cold stethoscope head is avoided by a disposable fabric cover. The cover is disposed between the stethoscope face and the patient'"'"'s skin and permits the patient'"'"'s chest sounds and the like to be transmitted through to the stethoscope face at a sufficient level to be amplified and rendered audible by the stethoscope. Such sound transmission may be through the fabric itself or through a port defined in the fabric radially inward from the periphery of the stethoscope face. An elasticized outer hem permits the cover to be easily placed onto and removed from the stethoscope. The inexpensive cover can be economically discarded after a single use and replaced so as to avoid transmission of contagious diseases between successive patients examined with the same stethoscope.

Claims

1. A method for preventing thermal discomfort to a patient being examined by a stethoscope while permitting sounds from the patient'"'"'s body to be transmitted to the stethoscope head, said method comprising the steps of:

(a) forming a stethoscope head cover from a sheet of cloth fabric having a periphery defining an area larger than a front face of the stethoscope head, said cloth fabric being conformable to the general shape of the stethoscope head; and

(b) removably deploying said cover over the stethoscope head such that said sheet overlies both the front face of the stethoscope head and a portion of the stethoscope head disposed behind the front face, said cover, when so deployed and when contacting the patient'"'"'s body,

(1) preventing thermal energy between the patient'"'"'s body and the stethoscope head; and

(2) transmitting sounds through the cloth fabric at a sufficient amplitude to be rendered audible by the stethoscope.

2. The method of claim 1 wherein step (b) comprises deploying said cover such that the entire front face of the stethoscope head is covered by the cloth fabric without interruption by holes or apertures.

3. The method of claim 2 wherein step (a) comprises forming said cover with an elasticized outer edge extending along the entirety of said periphery, said elasticized outer edge forming an opening smaller than a diameter of the stethoscope head so as to retain said cover on the stethoscope head.

4. The method of claim 1 further comprising the step of defining an aperture in said cloth fabric sheet, said aperture being smaller than the front face of the stethoscope head, and wherein step (b) includes deploying said cover such that said aperture is substantially centered over the front face of the stethoscope head.

5. The method of claim 4 wherein step (a) includes forming said cover with an elasticized outer edge extending along the entirety of said periphery, said elasticized outer edge forming an opening smaller than a diameter of the stethoscope head so as to retain said cover on the stethoscope head, and an elasticized inner edge surrounding said aperture.

6. The method of claim 1 wherein step (b) includes elastically engaging the stethoscope head with said cover.

7. The method of claim 1 further comprising the step of discarding said cover after a single use and replacing it on the stethoscope with a substantially identical cover.

8. The method of claim 1 wherein step (a) comprises forming said cover from flannel outing material.

9. The method of claim 1 wherein step (a) includes forming said cover as a generally circular portion of said sheet.
