Thinklabs One Digital Stethoscope with aux connection

Description

Q/A

Description

Thinklabs One Digital Stethoscope is an amplifying stethoscope with features that have crossed over into a new era. Recording sounds and playing them back for patients or analysis is now possible with the device. There are other similar devices such as this already on the market but Thinklabs has offered the best solution for sound in a crystal-clear format. With over 100-times amplification, compared to traditional stethoscopes. The stethoscope takes sounds such as a heartbeat and relays it back as best as possible audio.

The volume control allows you to raise or lower the output of sound that is heard - while filtering can be adjusted to listen for low, mid-range, or high frequencies. Audio output is made through an auxiliary port and can connect to high-quality headphones with no disruption to sound.

Product Controls and Display

An auto shut-off can be set so battery life can last longer. Charging the device is performed through the connection port, cable and wall-charger are provided. The package includes what you would need to plug-and-play. The stethoscope displays LED lights, indicating the settings currently selected.

The use of the stethoscope is simple. Made to be user-friendly and compatible with recent mobile and computer operating systems. If you are a healthcare professional that constantly uses a traditional stethoscope, you can offer a better experience for your patients and retain recordings from patients for following up on progress just as you would with any other diagnostic tool.

Headphone Adaptability

There are numerous medical studies that examine the utility of digitized stethoscopes, some of which have also tested the Thinklabs Stethoscope. Below are some of the study findings.

Cardiovascular disease (CVD) is recognized as the leading cause of mortality throughout the world. About 1/3 of global mortality is attributable to CVD. In addition to clinical presentation, specific clinical exam findings can assist in treating and preventing CVD. CVD may initially manifest as pulmonary pathology, and thus, accurate cardiopulmonary auscultation is paramount to establishing an accurate diagnosis.¹

The Thinklabs® One stethoscope is able to amplify sounds up to 100 times by applying capacitive transducer.20 This technology is able to employ ambient noise reduction but can also use specific heart sound extraction creating a rigorous tool to hear specific heart sounds such as valvular clicks as well as use specific computer algorithms to extrapolate frequencies to understand pulmonary pathology.²

A stethoscope has been designed to filter out ambient noise and reduce playback speed to better detect heart defect in newborns that have quick, quiet heartbeats. Results have shown improvements in regards to both sound optimizations.³

Closeup of the Diagnostic Device

The stethoscope was designed for high power output, with dedicated headphone amplifiers and has fully adjustable volume levels (1-10). The device can produce very high sound pressure levels and can exceed 100 times the decibel level of a conventional stethoscope. Five different filters allow the user to switch between listening for heart and lung sounds. In addition to filtering operations, adjusting the amount of pressure applied to the diaphragm alters the frequency response. Filter one ranges from 30 to 500Hz and filter two ranges from 60 to 500Hz, these low-pitched filters provide optimal auscultation for heart sounds. Filter three ranges from 80 to 500Hz and filter four ranges from 100 to 1000Hz, these filters are at a higher pitch, providing optimal auscultation for lung sounds. The fifth filter is a broadband filter ranging from 20Hz to 2000Hz +/- 3dB. The broad range of this filter lacks the specificity to filter out ambient noise but is ideal for recordings. The unit allows providers to select two filters as their "favorites" and set them for easy transition between the two filters. The LED lights are to serve as a visual indicator that the stethoscope is functioning. These LEDs also serve to indicate the volume level, current filter selection, and the device's battery life. The stethoscope contains a rechargeable lithium-ion battery that can be recharged through a USB port. A full battery charge provides four continuous hours of auscultation time, which provides 100+ patient assessments. To save battery life, it e has a customizable timer shut off that can be set between 1 and 10 minutes. If the user prefers, the stethoscope can be placed in a continuous "on" mode where the provider can manually turn the stethoscope off when not in use. It is designed to resemble the tactile shape and features of a traditional stethoscope, making it intuitive for users. The device was designed to be able to create audio recordings while auscultating. The stethoscope is compatible with both Mac and Android software. The manufacturer has designed an application (app) that allows audio recordings to be made with visual indicators.⁴

Although there is nothing wrong with traditional stethoscopes, taking the time to learn the nuances of computer-aided auscultation will improve your diagnostic capabilities. The stethoscope is perhaps the most iconic device associated with medical practice, and the most important part of the stethoscope will always be the part " between the ear tips."⁵

In this study, a single observer compared an analog stethoscope with the Thinklabs One electronic stethoscope in a clinical setting to determine if there was a significant difference in the diagnostic utility of the devices. Two hundred and nine patients were examined and the electronic stethoscope was felt to have superior sound quality in 65% of patients.⁶
