AUSCULTCARDIOGRAM
New to the QX Family

This is a sophisticated microphone that does not have a membrane. The skin of the patient becomes the membrane and thereby increases the function of the device by providing a biological membrane component to the microphone. The computer software then can filter aberrant noise and display the heart sounds on the screen. Royal Lee used a similar device to assess the nutritional needs of his patients. The QXCI device ia a similar but much more efficient device than the one used by Dr. Lee. This was originally called an echocardiogram. This term was developed for the ultrasound Doppler device that sends sound energy into the body and then interrupts the reflection or Echo. Since our device is totally safe sends in no energy, Echo does not apply.

Safety was our main focus on this development due to the growing concerns with the doppler type devices.

There are many heart sounds that reflect disease states...

The sounds come from the mechanical action of the heart valves

• A ECG reflects the electrical nature of the heart beat.

The QXCI allows you to do both so you can see the electrical nature of the beat while studying the mechanical nature the heart sounds.

How does it work?

The Auscultation system require a separate device that attaches to the serial port of your computer. Since the regular system attaches to the paralell port the two can operate simultaneously. The device has a microphone which is about 2.5 inches in diameter. There is a velcro beld provided that hold the microphone in place. There is a pressure sensor that can measure respiration's in a normal patient and muscle contraction in the pregnant patient.

Put the microphone over the chest of the normal patient and over abdomen of pregnant patient. MAke sure the rubber seal around the edge is all in contact with the skin. Plug in the power supply (9 volt dc). Turn on the switch and raise the volume till you hear the heart beat clearly.

The Start1 button will let you see the heart beat of the patient or the mother. The Start2 button will show the baby's heart beat.

The freeze button will freeze the last several heart beats over the last five seconds. ÛThen you can study and compare the pattern to other patterns revealed in the auscultation text.
