MN1-1173 Rev.16 1-1.Purpose of Use
1. PRECAUTIONS FOR USE 1-1.
Purpose of Use This equipment is intended to be used by doctors and other qualified persons for performing slice diagnoses and blood circulation diagnoses in the following parts of the human body. Do not use it for any other applications. • Thorax • Abdomen • Perineum and pelvis • Lower limbs • Back • Upper limbs • Head • Neck
Warning The acoustic power from this equipment exceeds the upper ophthalmological limit indicated in the U.S. FDA standards. DO NOT use this equipment for performing ultrasound diagnosis of the eyes.
Caution The intended use of probe differs depending upon the type of probe. Select a probe that meets your purpose of use. Do not use it for any application that is not covered in the instruction manual of the probe. The probe can harm the human body.
This section consists of 14 pages. 1-1
MN1-1173 Rev.16 1-1.Purpose of Use
1-1-1. Precautions concerning acoustic power The tissues of the human body consist of soft tissues, water, bone, and other tissues. Ultrasound energy is progressively absorbed and attenuated by the body as it penetrates it, hence tissues located behind water, which causes only a small degree of attenuation, receive a relatively large amount of ultrasound energy. Also, it is necessary to be careful of bioeffects due to heat in the vicinity of tissues, such as bone, that readily convert ultrasound energy into heat. Particularly, a fetus at the bone formation stage is exposed to a high risk of damage due to heating because almost all of the ultrasound energy passes through the amniotic fluid without being attenuated. Even in the case of a fetus prior to bone development, the cells are active, hence there is a possibility of growth being affected, even when the temperature rise is low. Pro-sound SSD-4000 shows the dynamics of blood flow using the Ultrasound Doppler Method. Mechanical bioeffects such as heating and cavitation occur when the body is exposed to ultrasound energy for a long period. You can reduce the risk of damage to the tissues by interrupting the ultrasound energy before it reaches the level at which tissue damage occurs. To this end, it is necessary to obtain a grasp of the functions of the equipment, acquire familiarity with the method of operating it, and understand the parameters that affect the acoustic power. Also, get into the habit of always freezing the image as soon as you have obtained the necessary diagnostic information.
Caution Minimize acoustic output power setting as low as possible within reason. Execute ultrasound scanning for only as long as it is necessary for diagnosis. Prolonged use can harm the human body.
1-1-2. Use with an ultrasound enhancing agent If you wish to use an ultrasound enhancing agent, be sure to use only a substance that has been approved for use as an ultrasound enhancing agent. Before using an enhancing agent, carefully read the instructions for using the enhancing agent and also any cautionary notes.
1-1-3. Use with a general pharmaceutical If you perform an ultrasound examination after having the patient ingest a general pharmaceutical, the ultrasound may affect the pharmacological effect of the pharmaceutical. Before using a general pharmaceutical, carefully read the instructions for using the pharmaceutical and also any cautionary notes.

Electromagnetic compatibility
1-6-1. The prevention of electromagnetic wave disorders This device meets IEC 60601-1-2:2001 which is the international standard for EMC with medical equipment. Medical devices are apt to emit electromagnetic waves or receive interference from electromagnetic waves. The EMC standard prescribes the testing of electromagnetic wave interference in transmitting and receiving. An electromagnetic wave transmit testing relates to electromagnetic wave interferences being transmitted from devices that are tested. The electromagnetic wave level that occurs from a device is called as "electromagnetic emission" and the tolerance of a device for the electromagnetic wave interference from other device is called as "electromagnetic immunity.

1-6-2. The guideline of electromagnetic compatibility Our ultrasound diagnostic devices have been confirmed that no electromagnetic waves against the electromagnetic wave interference standard are emitted by testing. As an ultrasound diagnostic device receives radio frequency signals ( supersonic wave signals on a Radio Frequency), there is a possibility to receive the electromagnetic wave interference that occurs from electromagnetic wave sources. As for the electromagnetic sources having possibility to generate electromagnetic wave disorders, there are medical equipment, communication devices, and radio or television broadcasting antennas. When cellular/mobile communication machinery such as cellular phones, transceivers, and amateur radio equipment are used, there can be effects affecting the operations of this device. The device should be placed apart from other electrical apparatuses (including medical use) as much as possible. When other electric apparatuses are installed in the neighborhood of this device, confirm the following. • Are there any adverse effects of the electromagnetic waves occurring from other equipment affecting to this device ? • Are there any adverse effects of the electromagnetic waves occurring from this device affecting to other equipment ?

The separation distances (m) based on the frequencies of transmitters
For a rated transmitter with its maximum output electricity not listed above, the recommended distance of d expressed in meter (m) can be decided by the equation corresponding to the frequency of the transmitter. The P in the equation is the rating of the maximum output electricity of a transmitter expressed in watt (W) by the transmitter manufacturing supplier. Remark1 Apply a high frequency band in separation distance for 80MHz and 800MHz. Remark2 These guidelines are not applicable for all situations. As for the electromagnetic diffusion, it is influenced by reflection or absorption of buildings, substance, and humans.
