• Remove all transducers from contact with the patient.
• Turn off the scanner. Unplug the scanner from the wall and make sure it cannot be
used until it has been checked.
• Do not remove the scanner cover.
Contact your BK Medical representative or hospital technician.
WARNING
Always keep the exposure level (the acoustic output level and the exposure time) as low
as possible.
WARNING
Service and repair of BK Medical electromedical equipment must be carried out only by
the manufacturer or its authorized representatives. BK Medical reserves the right to

Caution:
Keep all plugs and sockets absolutely dry at all times.
Starting Scanning
All equipment must be cleaned and disinfected before use.
Connecting the Transducer
The transducer is connected to the scanner using the array Transducer Socket on the
scanner. To connect, the transducer plug’s locking lever should first be in a horizontal
position. Align the plug to the scanner socket and insert securely. Turn the locking
lever clockwise to lock in place.
When connected, the transducer complies with Type BF requirements of EN60601-1
(IEC 60601-1).
Changing Frequency
The Multi-Frequency Imaging (MFI) facility enables you to select the scanning
frequency. See the applicable scanner user guide for instructions. The selected
frequency is displayed at the top of the screen .
Using a Transducer Cover
The transducer should be enclosed in a transducer cover or a standard condom. See
the Product Data sheet for a list of available transducer covers.
Apply gel to the tip of the transducer. This improves the screen images by preventing
image artifacts caused by air bubbles.
Pull the transducer cover over the transducer.
Gel also creates a good acoustic contact between the skin and the transducer;
therefore, apply a small amount to the outside of the cover prior to scanning. Re-
apply the gel frequently to ensure good screen images .
WARNING
Keep all plugs and sockets absolutely dry at all times.
WARNING
Because of reports of severe allergic reactions to medical devices containing latex ( natural
rubber), FDA is advising health-care professionals to identify their latex-sensitive patients
and be prepared to treat allergic reactions promptly.

Using the Transducer Control Button
The transducer has a control button that you can press to Start or Stop scanning
(freeze frame). Press the button for more than one second to make a copy of the
image.
Each time the button is pressed, a “beep” is emitted.
Changing Orientation
To change the orientation of the image on the monitor, refer to the applicable scanner
user guide for instructions.
Puncture Facilities
Puncture and biopsy is possible with Type 8870 transducer. The puncture attachment
is illustrated in the following pages with a brief description of its use and operating
instructions.
UA12 1
The puncture attachment (Figure 3) comprises a mounting bracket, which
secures the puncture attachment to the transducer handle, and a needle guide.
There are three screws marked A, B, and C in Figure 3 A is for securing the
puncture attachment to the transducer, B is to allow the needle guide to be
adjusted to three different angles of insertion, C is for holding the needle in
place.
To mount UA1251:
1 Mount the puncture attachment by fitting the metal mounting bracket on to the
transducer.
2 The metal raised knobs on either side of the transducer fit into the indentations
on the bracket. The ridge on the thin side of the transducer fits into the groove
on the bracket.
3 Tighten the screw (A) to secure the bracket to the transducer.
WARNING
Use only water-soluble agents or gels. Petroleum or mineral oil-based materials may harm
the cover materials.
WARNING
t is essential for the patient’s safety that only the correct puncture attachment is used with
Type 8870. Never use unauthorized combinations of transducers and puncture
attachments or other manufacturers puncture attachments.

8870 User Guide (BB1980-B) 9
Adjusting the angle of UA1251:
There are three different angles of insertion available; 30°, 45° and 60° with
respect to the transducer’s image axis.
1 Loosen screw B until the needle guide can move forward and backward.
2 Move the needle guide until it clicks into place in one of the three indentations
on the mounting bracket.
3 Tighten screw B until the needle guide is securely fixed.

Performing Puncture and Biopsy
Cover the transducer with a sterile transducer cover.
If the transducer cover is damaged when attaching the puncture attachment, replace
it with a new cover.
See the Product Data sheet for a list of available transducer covers.
Press the scanner Puncture or Biopsy control button to superimpose a puncture
line on the scan image.
If more than one puncture line is available, refer to the applicable scanner user guide
for instructions on how to change which one appears.
Move the transducer until the puncture line transects the target. Insert the needle and
monitor it as it moves along the puncture line to the target. The needle tip echo will
be seen as a bright dot on the screen.
WARNING
t is essential for the patient’s safety that only the correct puncture attachments, as
described in this guide, are used. Never use unauthorized combinations of transducers
and puncture attachments or other manufacturers puncture attachments.
Before beginning a puncture or biopsy procedure, always check that the type number of
the transducer and the type number or description of the puncture attachment match
exactly those displayed on the scanner monitor.
WARNING
The puncture line on the scan image is an indication of the expected needle path. The
needle tip echo should be monitored at all times so any deviation from the desired path
can be corrected.

8870 User Guide (BB1980-B) 11
To remove the puncture line from the image, refer to the applicable scanner user
guide for instructions.
