The address of the auscultation portal site is as follows.
Can this product（kikuzo）play a commercially available auscultation sound CD?
This product（kikuzo）has been developed on the premise of being used for playing auscultation portal sound sources. It is not recommended to use it as a commercially available CD player because it is out of scope.
However, because of the Kikuzo’s special feature of playing only the frequency band of the auscultation sound and cancels high-frequency sounds such as electronic noises, the sound may be clearer than when using earphones or headphones.
What types of sounds are available on the auscultation portal site?
A wide variety of typical auscultation sounds such as heart sounds, lung sounds, and bowel sounds, both normal and abnormal sounds are available, with the sound sources and descriptions.
Stethoscope quiz is also available for auscultation training.
I could feel the noise coming from the desk on which the product is placed. Is there a way to reduce noise?
As a noise prevention measure, soundproof rubber feet are attached to the back of this product. If you are concerned about noise, place a mat or something similar between the product and desk to reduce vibration.
Can I share my auscultation portal ID with others?

What is iPax?
IPax is the virtual auscultation simulator. You can study auscultation using a PC, and it can be used for both online and face-to-face classes.
How to use
You can use the service by entering the license key issued by us at the time of application.You can listen to the heart sounds and lung sounds of various cases.If you use the dedicated speaker Kikuzo, you can perform auscultation training with your own stethoscope. It also has the ability to auscultate while taking a pulse. For blood pressure measurement, not only auscultation but also palpation is possible.
What can we learn with this system?
You can learn auscultation of heart sounds, lung sounds, intestinal sounds, bruits, etc., and blood pressure measurement.With a dedicated speaker Kikuzo, you can auscultate with your own stethoscope, auscultate while taking a pulse, and touch the thrill in cases of heart murmur. As for cases, we cover all the cases necessary for medical education. In addition, if you have an electrocardiogram, echocardiogram, or other case scenario, we will customize the auscultation sound according to the information.Please contact us if you wish.
It says "1 license is required for 1 PC". Is it okay for everyone to use 1 unit?
This system can only be used on a PC that has been registered as a user. Therefore, if you want to register as a user on your own PC, you need to sign a license for each other. If you prepare a dedicated PC and register as a user on that PC, you can share and use that. However, please do not use it on the shared computer installed on campus.In the case of a shared computer on campus, it is often set so that the browser cannot be cached, in which case this system will not be available.
About the "test", how can we do that?
Exam questions can be displayed in this system. Exam questions are only available once, and you can have any number of choices and answer time limits for each question. The test results are recorded on the server and only the administrator can view the results. The management screen is provided by a separate contract.
About the actual usage of iPax (screen, volume, etc.)
Please tell me the meaning of the icon on the right side of the chest illustration.
From the top, the heart icon, pulse icon, and lung icon.Each time you press it, it switches ON / OFF.
What are the alphabets "A", "P", "T" and "M" on the precordial screen?
"A", "P", "T", and "M" are buttons for the aortic valve site (2RSB), pulmonary valve site (2LSB), tricuspid valve site (4LSB), and mitral valve site (Apex), respectively.When you press the button, the chestpiece moves to that part and you can hear the sound of that part.
Can we auscultate only the precordium?
You can also auscultate the back.Press the arrow next to the left shoulder to switch between the precordium and back.
What should I do if I can’t hear the sound?
Press the circular arrow (refresh) button at the bottom left of the screen. The sound source file is reset and you can listen to the sound again.
I think the sound is small.
Check the volume of your computer and the volume of Kikuzo.When the volume of the computer is 50 to 60%, the volume of Kikuzo is set to the minimum so that it can be heard at the same volume as the living body.If the surrounding environment is noisy or you feel the volume is low, increase the volume of Kikuzo. If the volume does not increase even if you turn up the volume of Kikuzo, replace the battery Kikuzo with a new one. If you want to output a pulse from Kikuzo, set the volume of Kikuzo to maximum.
Where can I find palpation content for blood pressure measurements?
Select "Palpation" from the "Category, Drop-down Menu" on the "Library" page. The content of the blood pressure exercise is displayed, where palpation and auscultation cases are available. When using this content, please connect two Kikuzo to using the L / R branch cable. Please maximize the volume of Kikuzo on the palpation method side and minimize the volume of Kikuzo on the auscultation method side.
I want to palpate with Kikuzo, but I can’t touch the pulse or thrill.
For pulse or thrill, turn Kikuzo’s volume dial to maximum. A good computer volume is 50-60%, but if you still can’t touch it, replace the Kikuzo battery with a new one.
I don’t know how to palpate the pulse.
When two Kikuzo units are connected, a pulse is output from the black terminal side. When the volume is maximized, the silicon part on the top of Kikuzo vibrates like a pulse. Palpate with your finger lightly (please note that pressing hard will make it difficult to touch). Regarding the connection method, connect the "L / R branch cable" to the personal computer, and connect Kikuzo to each of the L side and R side. You can touch the pulse and thrill by maximizing the Kikuzo volume on the pulse side (black terminal side). Make sure that the terminals are firmly connected and that the batteries are not old before using.
It takes time to load the case with iPax. Why?
Many sound sources are placed in iPax. The PC reads and plays those sounds.If the communication is delayed or the computer is busy, the reading time will be longer.We recommend a computer memory of 16MB or more to improve the iPax usage environment. If you have a low-spec computer, it will take some time to load. If it is difficult to change the computer, please contact us as we will change to a case with less load on the computer (auscultation time is short and there is no pulse function).
Can iPax be used on smartphones and tablets?
Student content (iPax cases without pulse function in a short time) can be used on smartphones and tablets. It can be used on both Android and iOS.
