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 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 • Cranial nerves • Neck

Warning DO NOT use this equipment for performing ultrasound diagnosis of the eyes. The acoustic power from this equipment exceeds the upper ophthalmological limit indicated in the U.S. FDA standards.

Caution (1) The intened use of probe differs depending upon the type of probe. Select a probe that meets your purpose of use.. (2) Probes come in a variety of shapes and sizes to suit different applications, so be sure to use the right probe for each application. If you use an unsuitable probe, you may cause injury to the patient. (3) The probe can harm the human body. Do not use it for any application that is not covered in the instruction manual of the probe.

This section consists of 14 pages. 1-1

MN1-0921 Rev.10 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. 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 (1) Use as low an output as possible within reason. (2) Scan the body for only as long as is necessary to make a 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.

Probe

Type BF equipment

All probes

Table Classification according to degree of protection [Remark] Type BF refers to ultrasound diagnostic equipment that uses only ultrasound probes that are intended for applications not involving direct contact with the heart.

1-2-3. According to the degree of protection against harmful ingress of water • Ordinary equipment

Warning The equipment is not protected in any way against water ingress, so do not use it in a place where there is a possibility of water getting into it. Take care not to spill liquid onto or into the equipment. This is because of the danger of electric shock. If you do happen to spill liquid on the equipment, contact one of Aloka's sales offices or agents listed on the back cover of this instruction manual.

1-2-4. According to the degree of safety of application in the presence of a flammable anaesthetic mixture with air or with oxygen or nitrous oxide • Equipment is not suitable for use in the presence of a flammable anaesthetic mixture with air or with oxygen or nitrous oxide.

Danger Do not use this equipment in a flammable atmosphere. It may cause an explosion if used in such an atmosphere.

Safety Warning Do not remodel or modify equipment. Unexpected accident can take place.

Warning Clean and disinfect a probe every time it is used. Using contaminated probes may result in infection.

Warning Wear medical gloves during inspection, and wash your hands after inspection; otherwise you may become infected from patients.

Caution Hold a probe tightly not to slip, especially when using ultrasound gel or others; otherwise, the probe may slip out of your hands and hit a patient. Avoid rapid temperature change which may cause condensation. Avoid using where condensation exist.

Caution Always use this in dried state. Condensation may appear when using from cold to warm places. Use without proper care, then, can cause short-circuiting.

Caution Use of an ultrasonic beam into the air without coating the probe with an ultrasound medium, may cause surface temperature to rise. Before using, coat probe adequately with ultrasound gel.(*) When probe is not in use even during an examination, freeze image. In the event that the surface temperature feels abnormal, immediately stop using the probe, and contact our office. (*) When performing a puncture or a surgical operation, use ultrasound medium as described in the instruction manual for the probe.

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.

Caution (1) Install this equipment where the electromagnetic radiation does not affect. Note that the electromagnetic radiation may cause the following phenomena on this equipment. • Distortion in viewing monitor • Noise on physiological signals • Noise from loudspeaker • Noise on image (2) Position this equipment and its cables (e.g. probe cables, ECG cables, I/O cables, etc.) as far away as possible from other medical electrical equipment. (3) Note that electromagnetic radiation from this equipment may cause the abnormal operation on the other medical electrical equipment nearby. In this case, stop using such equipment immediately. (4) This equipment intended to use in hospitals and/or institutions in order to prevent the electromagnetic interference. Use this equipment in facilities equivalent to the hospital or institution. Note that electromagnetic radiation from this equipment may cause the disturbance to the radio receiver, TV set, etc. Position this equipment as far away as possible from the radio receiver, TV set, and its cables and antenna. (5) Do not use the portable radio communication devices (e.g. cellular phone, cordless phone, radio transceiver, etc.) near this equipment.
