How does the new the Meditron Analyzer look like? Is it different from the one we know?

Answer :
Yes , the connector has been redesigned, allowing you to choose between analog Line IN / Line OUT or Digital USB connection. The ECG board is now placed inside the connector and color rings in the connector box clearly indicate where to put your ECG electrodes. We also added a recording volume control now. Take a look:

 

Can I buy/order different versions from the analyzer now?

Answer :
The product itself comes as is shown in the picture and the former type of connector has been taken out of production.

The Meditron Analyzer comes in two versions as before: one for human medicine and one for veterinarian medicine. The difference between the human version and the veterinarian version is most importantly on how to register a patient, in the veterinarian version the animal/owners etc. The length and type of ECG cables that come along with the box and the filter settings differ. The different versions are marked with “H” for human use and “V” veterinarian use.

 

Does this new analyzer work on every computer now?

Answer :
Assuming that the system requirements are met, there should be no computers where this would not work assuming that system requirements are met- Windows 98, ME, 2000 or XP

  • Pentium Class PC
  • 64MB Ram or more
  • 40MB free hard disk space or more
  • USB or Analog (Line IN/Line OUT) with Soundblaster compatible soundcard.

 

Does the Meditron Analyzer run on Macintosh computers?

Answer :
No, the Analyzer software was written to operate under Windows.

 

Can I upgrade my existing The Meditron Analyzer with only the new hardware? Can I still use my old software?

Answer :
No: If you wish to upgrade, you need both new software and hardware. Please check with your distributor if there are special offers for existing customers.
Note : If you currently have version 3.0.2, and your analog connection works fine, there is no need to upgrade at all.

 

What about the sound files already in the old version – are they being automatically imported into the new version?

Answer :
Yes, the old files are kept and linked to the patients as before upgrading. However, as a general rule, always make a backup of your old directory on regular intervals and especially when working with installations or upgrades.

 

What version of the software do I use now?

Answer :
If you open your Analyzer, look in the blue bar at the very top of the program window. The Meditron Analyzer version number is stated immediately following the name Analyzer.

 

How do I upgrade my existing software with the new software?

Answer :
After backup has been done simply insert the new CD and follow instructions for new installation that will appear automatically on you computer screen.

 

Are there changes in functionality in the new software?

Answer :
No : Except for certain minor changes to allow the USB connection to work properly, the functionalities are the same. In other words you or the customer will not notice a change in the use of the program

 

Why is it possible to use two different connections to use the Meditron Analyzer? I mean I have an USB connection and I also can use the analog line in/out?

Answer :
You must choose either digital USB or Analog Line IN/Line OUT connection. You should not use both. Please refer to your computer manual to verify what your hardware allows for. If you can use both connections, we recommend you to use the USB connection because of the ease to use.

 

What is actually the difference between an analog signal and a digital signal?

Answer :
All signals are in analog form before entering a computer. Being in an analog form means that the signal comes in a continuous stream of electrical pulses. Before the computer can understand this analog signal it has to be converted into digital (Binary) form. This means that the signal now comes in as a stream of digits. (Zeros and ones). The process of digitizing the sound in a computer is usually done in a soundcard that is installed inside the computer, or an external A/D converter, such as our new USB connector, must do the digitization process. For all practical purposes the quality between analog and digital is equal.

 

Does the USB version provide better sound quality than the analog version?

Answer :
This can only be answered by comparing with the individual soundcards installed in the various computers. In average and for most practical purposes the signal will be of very similar quality.
Note: when working with a laptop it is better to unplug the power supply for better quality recordings.

 

Do I need to inform all my existing customers that have bought the analyzer earlier about this new version?

Answer :
No, as long as they have installed the analyzer properly and are happy with the current version, there is no need to upgrade to a USB connection. The primary motive for introducing the USB version was to offer a solution to those who did not have analog connection or to those who found the installation process very cumbersome. The installations should be easy now, “Plug and Play”

 

What windows version should I have to run the new analyzer perfectly?

Answer :
Windows 98, ME, 2000 or XP.

 

Will we encounter installation difficulties? The earlier versions were sometimes difficult to install with regards to the settings of recording and playback?

Answer :
The USB solution is avoiding the use of the computers' soundcard, thereby bypassing these settings here referred to. The installation process should be very simple.

 

What is the best way for me to play back the recorded sound files?

Answer :
We recommend using the Meditron Stethoscope or the Meditron Headsets/Distributor to appreciate the sounds fully. This is also the way the doctor heard the original sound from the patient. If computer speakers or external speakers are used, the audio characteristics of using a stethoscope changes, and details may be lost to the listener.

 

Why did you develop this product with a USB connection?

Answer :
The trend among computer manufacturers is to focus more and more on USB as main port for external equipment such as audio. More and more the soundcard is not even installed, forcing users to find other solutions. We have taken the consequence of this development with the introduction of the USB connector. The whole installation process of the Meditron analyzer also then becomes much easier as the soundcards needs no longer to be set properly.

 

I think the analyzer is an expensive product. Why is it so expensive?

Answer :
The Analyzer includes very sophisticated software, but most importantly the hardware includes circuitry boards that handles many functions, i.e. amplification, A/D conversion. ECG and patient protection against spikes of high voltage. The Meditron analyzer is a unique product and should have a similar price as other software packages like Windows.
Note: For a doctor or veterinarian it is possible to charge the customer/owner a small fee for a recording so he/she can see some return on his investment.

 

Does the new the Meditron Analyzer have a different product coding?

Answer :
No the product coding remains the same. The product codes are:

  • 5079-402 For the human version
  • 5079-402V For the veterinarian version

 

What is the Meditron Analyzer?

Answer :
The Meditron Analyzer is a software/hardware package that allows body sound (heart and lung sounds) to be recorded, visualized and played back. An ECG tracing is recorded simultaneously, providing a secure means of synchronizing the heart cycle as well as heart rhythm. The Analyzer must be used in conjunction with a Meditron Stethoscope. Until now the possibility of recording heart-sounds and a synchronized ECG signal is unique in the world.

 

What does it do? Can I get a diagnosis from it?

Answer :
You may use the Meditron Analyzer as a diagnostic aid, giving you more information than what you can get from simply listening to a stethoscope. However, there are no diagnostic functions in the software; the doctor is still responsible for the diagnosis.

 

Why should I use it – what is the clinical benefit?

Answer :
The Meditron Analyzer gives you the opportunity to visualize and play back sounds over again whenever you want and wherever you want. Adding one more sensory dimension together with repeating the sound will increase the certainty of the diagnosis. "See what you hear – Save what you see". Additionally you may document all your auscultatory findings, something that was never possible before, and you may monitor patients over time. You may even seek advice from an expert if needed using the sound files in a tele-medical fashion in other words to get a second opinion. Early diagnosis – Better prognosis.

 

What about telemedicine – how does that work?

Answer :
You may send sound files electronically to a specialist for a second opinion. Or, if a tele-medical network is in place, sounds may be streamed directly from one site to another. It allows for a quick sharing of medical information.

 

What types of stethoscopes can be used with it?

Answer :
The Meditron Stethoscopes come in two versions, The Master Elite (or Meditron M30) and the Master Elite Plus (or the Meditron Stethoscope). Both can be used equally with the Analyzer USB.

 

Can it be connected to the teaching unit? How?

Answer :
The Analyzer may well be used in conjunction with the Meditron Distributor and Headsets. The Distributor is then simply connected between the Stethoscope and the Analyzer using the same cables:
Stethoscope to Master port on Distributor/ then PC port on Distributor to Steth port on Analyzer/ then USB or Analog connection to computer.

 

I would like to import a sound file in a PowerPoint presentation? How do I do that?

Answer:
We recommend switching from using Power Point application to using the Analyzer software during the presentation by pressing ALT-Tab. This technique will allow you to quickly switch between the programs while still in PPT presentation mode and you keep all the flexibility of the Analyzer.
Should you insist on running an animation of an Analyzer file your options are to:

  • Have a Flash animation made from an Analyzer screenshot, then importing this into Power Point. This is to our knowledge only possible in Power Point version 2002.
  • Insert a wav file directly (only hear sound)

 

Is the Meditron Analyzer ECG compatible to my patient journal software at my office?

Answer:
How do I connect the analyzer to it? I want sounds file to be saved in the electronic patient journal on my PC.
Please contact your vendor with questions regarding your specific software questions, or contact Meditron directly at: support@meditron.no

 

When should I use spectral view and what is the clinical benefit?

Answer:
The spectral view shows frequency vs. time instead of amplitude vs. time. The benefit from this is that you can more easily see sounds such as crackles, wheezes and other lung sounds. The warmer the color (orange-red), the more sound is present in a particular frequency area. Likewise, colder colors (green-blue) represent areas with little or no sound present.

 

What about the 3D view?

Answer:
The 3D view combines the two other views and displays amplitude, frequency and time, all in one view. You can now see a cubic view of the sound. No textbooks in medicine will refer to this novel approach, but for research into body sounds this view provides more information than a two-dimensional view. To turn the cube, place the mouse marker on an area of the cube, then when holding both left and right mouse tab down, move the mouse until you have the desired view.

 

Why can I not playback at half speed?

Answer:
In the current version of the Analyzer this is not possible, as reducing speed will alter the sound, much like playing music on a slower speed. In order to compensate this by increasing the pitch of the sound, sophisticated algorithms are needed. We are currently investigating these algorithms.

 

What lead is recorded with the ECG?

Answer :
It is lead II that is recorded with the latest USB version.
