Device Description and Intended Use

ADC®aneroid sphygmomanometers are used by professional healthcare providers and individuals trained in auscultatory
blood pressure technique to determine systolic and diastolic blood pressure in humans and animals.

A warning statement in this manual identifies a condition or practice which, if not corrected or discontin­ued immediately could lead to patient injury, illness, or death.

CAUTION: Federal law restricts this device to sale by or on the order of a physician or licensed healthcare practi­tioner.

WARNING:

If luer lock connectors are used in the construction of tubing, there is a possibility that they might be inad-

vertently connected to intra-vascular fluid systems, allowing air to be pumped into a blood vessel. Immediately consult a

physician if this occurs.

WARNING:

Do not allow a blood pressure cuff to remain on patient for more than 10 minutes when inflated above 10

mmHg. This may cause patient distress, disturb blood circulation, and contribute to the injury of peripheral nerves.

WARNING: Safety and effectiveness with neonate cuff sizes 1 through 5 is not established.

WARNING:

Do not twist connectors when joining the blood pressure cuff to tubing as this may cause the connectors to

stick and make changing the blood pressure cuff difficult.

WARNING:

When using with an infant or child cuff, extra care must be taken to prevent over-inflation. With smaller

cuffs (infant or child) the cuff can inflate to over 300mmHg with just two full compressions of the bulb. To prevent dis­comfort or injury to the patient and damage to the instrument, bulb should only be partially squeezed, so that each “stroke”
inflates the cuff in 40mmHg to 60mmHg increments until inflated to the desired level.

WARNING:

This product may contain a chemical known to the state of California to cause cancer, birth defects, or other

reproductive harm.

Connecting the Inflation System to Manometer

Remove the red cap which seals the reservoir containing mer­cury. Attach the free end of reservoir tube securely to air inlet.
Save red safety cap for later use. When transporting mercury
instrument we recommend replacing the red safety cap.

Please note: It is normal for negligible amounts of residual
mercury droplets to accumulate around the air inlet beneath
the red safety cap during transportation.

Warning:Before transporting this instrument, mercury must be stored in the tank and the reservoir lock
MUST be switched to the off position to prevent mercury spills.

Operating Instructions

Your DIAGNOSTIX™ 922 Desktop Mercury Sphygmomanometer incorporates a special safety feature that locks the
mercury within the reservoir during storage, transport, or maintenance.

To Operate the 922: To release the mercury from the reservoir, move the locking lever to the left. Mercury will flow
up into the plastic cartridge tube and rest at the “0” mark. If the mercury doesn’t rise within the tube, tilt the entire
unit 45° to the left. If mercury fails to rise, or doesn’t reach the “0” level, have unit serviced.

To Lock Mercury within the Reservoir: Tilt the entire unit back 45° towards the reservoir to permit mercury to
flow out of cartridge tube and into reservoir. When cartridge tube is completely emptied of ALL mercury (and
while it is still tilted 45°), move locking lever to the right. Mercury should be locked within the reservoir during
maintenance or transport.

PLEASE NOTE: MERCURY SHOULD BE SECURED WITHIN THE RESERVOIR BEFORE CLOSING LID, DURING
TRANSPORT, OR WHEN SERVICING THE CARTRIDGE TUBE, DIAPHRAGMS, OR FILTERS. NEVER DISAS­SEMBLE UNIT UNLESS MERCURY IS FIRST LOCKED WITHIN RESERVOIR.

MEASUREMENT PROCEDURE

1. Patient Position

The patient should sit or lie comfortably. The arm should be fully sup­ported on a flat surface at heart level. (If the arm’s position varies, or is
not level with the heart, measurement values obtained will not be consis-

tent with the patient’s true blood pressure.) Observer should view
manometer in a direct line and at eye level to avoid “parallax error.”

2. Apply the cuff
ADCUFF™ nylon cuffs, with proprietary Size Guide™marking system,

are specially designed to promote the precise, accurate determination
of blood pressure. Index and range markings ensure use of the correct cuff size. The artery mark indicates proper cuff
positioning.Place the cuff over the bare upper arm with “artery” mark positioned directly over the brachial artery. The
bottom edge of the cuff should be positioned approximately one inch above the antecubital fold. Wrap the end of the
cuff, not containing the bladder, around arm snugly and smoothly and engage adhesive strips. To verify a correct fit,
check that the ADCUFF

hesive strips. To verify a correct fit, check that the INDEX line falls between the two RANGElines.

3. Inflate the cuff
Close the ADFLOW™valve by turning thumbscrew clockwise.

Palpate the radial artery while inflating the cuff. Be sure to inflate cuff quickly by squeezing bulb rapidly. Inflate cuff 20­30mmHg above the point at which the radial pulse disappears.

4.Position the Stethoscope
Position the chestpiece in the antecubital space below the cuff, distal to the brachium. Do not place chestpiece underneath
the cuff, as this impedes accurate measurement. Use the bell side of a combination stethoscope for clearest detection of
the low pitched Korotkoff (pulse) sounds.

5. Deflate the cuff
Open the valve to deflate the cuff gradually at the AHA recommended rate of 2-3mmHg per second.

6. Measurement
Record the onset of Korotkoff sounds (Phase 1) as the systolic pressure, and the disappearance of these sounds (Phase

5) as the diastolic pressure. (Some healthcare professionals prefer recording diastolic 1 and diastolic 2. Diastolic one oc­curs at phase 4).

After measurement is completed, open valve fully to release any remaining air in the cuff. Remove cuff.

Care and Maintenance

Warning:Before transporting this instrument, mercury must be stored in the tank and the reservoir lock MUSTbe switched

to the off position to prevent mercury spills.

Storage
After measurement, wrap cuff around bulb and store in base of main unit. IT IS NOT NECESSARY TO CLOSE
UNIT AFTER EACH USE - HOWEVER, ALWAYS REMEMBER TO LOCK MERCURY WITHIN THE RESERVOIR BE­FORE CLOSING LID.

Manometer Periodically replace the filter plug and diaphragm, and clean the inside of the plastic cartridge tube using alcohol

and a lint free pipe brush. Units should be cleaned and serviced periodically depending on frequency of use, or whenever in­side of cartridge tube appears dirty. Proper servicing of your mercury unit according to a strict maintenance schedule will as­sure maximum measurement accuracy and extend the life of your instrument.

For directions on disassembling the unit refer to the enclosed schematic diagram and accompanying instruc­tions.

PLEASE NOTE: MERCURY IS TOXIC. SECURE MERCURY WITHIN THE RESERVOIR BEFORE SERVICING UNIT.
ALWAYS WEAR PROTECTIVE CLOTHING (GLOVES AND GOGGLES) WHEN CLEANING OR SERVICING THE
UNIT. CLEAN ANY SPILLED MERCURY PROMPTLY USING APPROVED MERCURY CONTAINMENT KITS. ONLY
PROPERLY TRAINED SERVICE TECHNICIANS SHOULD ATTEMPT TO SERVICE THE UNIT. CONSULT THE EN­CLOSED MANUAL ENTITLED “JUST IN CASE” FOR PROCEDURES ON DEALING WITH A MERCURY SPILL.
