Question 6

Can I use a chest piece other than Littmann's?

Accepted Answer

Some connections can be made depending on the shape of the connection, but this has not been verified.
Please try using the O-rings and tubes that come with Nexstetho.
Please note that Littmann Master Cartiology is not compatible.

If you are not sure about the installation, there is a chest piece kit with a custom-made Focal chest piece.

Want to try before you buy, or want us to come to your place for a demo?

Accepted Answer

Not available for rent.

Question 8

What causes weak or inaudible heartbeat, breath sounds, or other specific sounds?

Accepted Answer

Sound quality often depends on the performance of headphones or earphones and speakers. Products with excellent reproduction capabilities, especially in the low frequency range of 20hz to 60hz, are desirable. We have tested the connection and sound quality, and have compiled a list of products that we believe are compatible with Nexstetho, which we hope you will refer to. (Updated as needed)

Question 16

I have a hearing impairment and cannot perform auscultation. Can I use Nexstetho for auscultation?

Accepted Answer

Since the degree of disability varies from person to person, some people seem to benefit from it while others do not.
However, there have been reports of nurses with cochlear implants who have been able to hear again with Nexstetho. Please consult your specialist.

I was so happy and moved to tears because it brought back the nostalgic feeling I had when I was healthy.

Question 17

Can hear ambient sounds, but cannot hear heartbeat

Accepted Answer

Depending on the situation, try the following
 
If you feel the heartbeat is weak, press the I button on the Nexstetho main unit.
Pressing the Ⅰ button will enter a mode that makes it easier to hear the heartbeat.
Make sure that the chest piece is securely installed all the way to the back with no gaps or wobbling.
Please use the supplied O-rings and tubes to adjust the fit.
If you cannot hear the heartbeat completely, the direction of the chestpiece opening may be reversed. Please remove the chestpiece from Nexstetho once, turn the middle shaft, and then put it back.

Question 18

Strong feedback and cannot be heard through the speakers.

Accepted Answer

The tips to avoid feedback are as follows.
Place the speaker at a distance from the main body of Nexstetho.
Place the speaker facing backward.
Wrap the main body of the speaker in a towel, etc. Heartbeats and other sounds are low frequency and can be heard even when wrapped in a towel.
In this environment, we hope you will try to increase the volume of the speakers as needed.

Question 19

ヘッドフォンとBluetooth接続できなくなった

Accepted Answer

問題なく利用できていたイヤフォン・ヘッドフォンとのBluetooth接続が切れ、再接続できなくなってしまった場合
まずはデバイスとの再ペアリングを試みてください。

ペアリングができなかった場合には、複数の出力デバイスとネクステートのペアリングを試みてください。

ネクステート本体に問題がなさそうな場合には、ご利用になられていた出力デバイス側の設定の見直しや初期化等をお試しください。

いずれの検証でもネクステートとの接続が復旧しない場合には、ネクステートの不良の可能性があります。
その際には弊社にお問い合わせください。
