Parts and Assembly
This booklet contains operating and maintenance information for the DI-
AGNOSTIX™ 952 series wall mount mercurial blood pressure instrument.
Please read and retain.
Your DIAGNOSTIX™ 952 consists of a main unit with a 5mm calibrated
unbreakable plastic cartridge tube, inflation system (which includes the
ADCUFF™ nylon cuff with Size Guide™ marking system, latex-free infla-
tion bladder, bulb, and ADFLOW™ valve), 8 ft. length of coiled tubing,
luer connector, separate cuff basket, mounting hardware, and operating
instructions.
To assemble, connect coiled tubing to air inlet nipple at bottom of main
unit. Insert male luer adaptor on bladder tubing into female receptacle at
free end of coiled tubing. Store folded inflation system in convenient cuff basket.
Consult booklet entitled “DIAGNOSTIX TM 952B Wall Mounting Instructions” (Enclosed).
Operating Instructions
Your DIAGNOSTIX™ 952 Wall Mount Mercury Sphygmomanometer incorporates a special safety feature that locks the mercury within
the reservoir during storage, transport, or maintenance.
To Operate the 952: To release the mercury from the reservoir, turn the lever to the “ON” position. 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 top of the unit towards you
(unit must be removed from wall bracket). If mercury fails to rise, or doesn’t reach the ”0” level, have unit serviced.
To Lock Mercury within the Reservoir: Remove instrument from wall bracket by loosening butterfuly nut at base of
swivel bracket. Tilt the top of the unit away from you 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), move locking lever to the right “OFF”.
PLEASE NOTE: MERCURY SHOULD BE SECURED WITHIN THE RESERVOIR DURING TRANSPORT, OR WHEN SERVICING
THE CARTRIDGE TUBE, DIAPHRAGMS, OR FILTERS. NEVER DISASSEMBLE UNIT UNLESS MERCURY IS FIRST LOCKED
WITHIN RESERVOIR.
CONSULT SEPARATE INSTRUCTIONS FOR WALL MOUNTING (ENCLOSED).
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 consistent 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 INDEX line falls between the two RANGE lines.
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 20-30mmHg above the point at which the radial pulse disappears.
