Teaching With the Thinklabs One Digital Stethoscope

One of the biggest benefits of the Thinklabs electronic stethoscope is in teaching. The stethoscope is shipped with an adapter known as ThinkLink. You can connect the stethoscope chest piece to your smartphone and then to your earbud/headphones through the ThinkLink. When you connect the stethoscope to your smartphone, you will not only be able to auscultate the patient but can also record the lung or heart sounds to its app or other third-party recording apps.

When teaching, residents or students can hear sounds and find out at once through a speaker as a group instead of having each student come to examine a patient multiple times.

In some clinical settings, you can attach a Bluetooth adapter to the chest piece. From there you can use Bluetooth headphones and then use the device on a patient that may have been isolated for precaution purposes. The ThinkLink also makes telemedicine easier. For example, a doctor on one end can hear the heart or lung sounds in real-time rather than waiting for a recording.

Thinklabs One is light and easy to use. If you do not like to wear the coat while working in the ER, you will immediately notice how heavy other stethoscopes have been when you switch to using the Thinklabs. The stethoscope is quite sensitive, even at the lowest settings, compared to non-digital options. You can use various headphones with the device to hear sounds better.

Using Thinklabs with Hearing Aids

The Thinklabs One stethoscope works with hearing aids. It has various options for different hearing aid styles and earphones. Therefore, you won’t be bothered to remove them when using the stethoscope. You can also use the stethoscope with a streamer and headphones. However, the stethoscope is so loud that you may not even need a hearing aid or anything else to amplify lung, heart and other body sounds.

Generally, hearing aids do not do a good job at reproducing bass sounds. Therefore, you won’t get the direct benefit of the huge power output of the Thinklabs One if it has to go through the hearing aid. To get the best quality sound with the One, make sure your hearing aid is programmed for maximum bass.

If you have an open-fit hearing aid, you can use the One with headphones. You need a good pair of headphones to get the best results from the stethoscope. The headphones should be comfortable and have a good bass response.
