Choose a tubing adapter (Narrow Slim, or Straight Fit)
To get the best sound, we recommend you test all Eko-supplied tubing adapters and select the one that provides the tightest fit with your analog stethoscope.
Step 1: Detach the Chest Piece
Remove the chest piece of the analog stethoscope manually. Grip the chest piece with one hand and the tubing in the other, pull them apart. This may require some force.
See Figures 1 and 2 below.
Step 2: Install Tubing Adapter & Eko Core
Insert the small end of the Eko Core (the end of the Eko Core with the smallest diameter) into the open tubing of the analog stethoscope. Next, place the slim fit adapter onto the stem of the stethoscope chest piece (as shown in Fig. 3). Now, place the stethoscope chest piece with the attached adapter onto the open stem of the Eko Core (as show in Fig. 5).
Step 3: Reattach Tubing and Chestpiece
Attach the piece of additional tubing onto the end of the Eko Core hardware as shown below. Then attach the chest piece into the connector tubing as it was on the analog stethoscope. Ensure that the large end of the Eko Core is towards the head of the stethoscope.
