Instructions for Use (English)
CAUTION
• U.S. Federal law restricts this device to sale by or on the order
of a physician.
• Vacuum gauges can be rendered inaccurate during shipment
despite care taken in packaging. Gauge calibration must be
checked before each use.
• The Mityvac reusable obstetrical vacuum pump is
manufactured and individually tested in strict adherence to
specifications. Any repair or maintenance performed by
anyone or entity other than the manufacturer could
compromise the integrity of the pump and is done so at the
risk and liability of the institution performing the work. All
Mityvac reusable obstetrical vacuum delivery pumps should
be thoroughly checked for proper performance and gauge
calibration prior to each use.
DEVICE DESCRIPTION
The Mityvac reusable obstetrical vacuum extraction pump delivers the
®
vacuum needed to aid in delivery of the fetus in both vaginal or
Cesarean births. It is hand-held, manually operated and may be used in
the proximity of oxygen. The Mityvac reusable obstetrical vacuum pump
may be used either inside or outside of the sterile field.

IMPORTANT INFORMATION ABOUT YOUR MITYVAC PUMP
We recommend that you check the equipment and the calibration of the
gauge before each use.
Your pump's useful life may be extended if you follow these
precautions:
1. Avoid drawing fluids into the pump during the procedure.
2. Remember that the Mityvac reusable obstetrical vacuum pump is a
delicate instrument and should be handled accordingly.
3. The Mityvac reusable obstetrical vacuum pump should be sterilized
using the Moist Heat Validation Sterilization Process, as indicated
within the Sterilization Instructions.
4. To prevent breakage, do not force the pump handle. If operation
becomes too difficult, lubricate piston shaft by adding a few drops of
medical grade silicone oil (non-petroleum based) into the pump
vacuum nozzle.
5. Do not twist tubing on the pump vacuum nozzle to remove it. Doing
so may cause undue stress on the pump junction. Simply use the
tubing remover supplied to easily remove tubing from pump.

SETTING UP THE SYSTEM
1. Check to ensure the pump needle is in its resting position within
the zero box on the gauge.
2. Connect the sterile tubing to the pump vacuum nozzle (with cup,
or with cup and filter already assembled).
3. Now check for integrity of system by pumping with cup pressed to
flattened palm of gloved hand. Rapidly pump until the gauge
needle is in the green area between 38 and 58 cm Hg (centimeters
of mercury) or between 15 and 23 in. Hg (inches of mercury).
Gauge needle should
move upon initiation
of vacuum. Once the
desired vacuum level
is reached the gauge
needle should
remain steady.
4. If gauge needle does not
remain steady during test
pumping:
• Check cup pressed
to palm. The lines in
your hand may be
causing the vacuum

• Check the connection of tubing to pump vacuum nozzle. Be sure

8. When delivery has been completed, remove tubing at pump and
dispose of extractor cup unit. The pump may be cleaned for reuse.
Using the tubing remover
Snap tubing remover into place with pump
vacuum nozzle in hole and tubing remover legs
around junction (Figure A).
Removing the tubing
Hold pump in hand with fingers on top pad section
of tubing remover. Press toward gauge and tubing
remover will "rock" tubing off of pump vacuum
nozzle (Figure B).
In an extremely tight tubing fit, the hand may be
reversed and the thumb, or both thumbs, may be
used to press the pad section.
