VACUUM-ASSISTED VAGINAL DELIVERY GUIDELINES
1. Connect cup to pump using sterile suction tubing.
2. For Electric Vacuum Source: Connect sterile cup, tubing and
connector (order P/N 910000-310064) to the electric vacuum pump
by placing the tapered end of the connector securely into the hole
of the collection jar lid. Preset the desired vacuum levels at the
vacuum source. Refer to the Vacuum Conversion Chart as
necessary.
CAUTION: DO NOT USE DEVICE IF GAUGE NEEDLE DOES NOT
INDICATE ZERO IN THE ABSENCE OF A VACUUM.
3. Check the integrity of the Mityvac Obstetrical Vacuum-Assist Delivery
System by pressing the cup to the palm of your gloved hand and
applying vacuum. The gauge needle should remain steady.
(NOTE: The gauge needle should rest in the "ZERO" box when
vacuum is not applied.)
4. Carefully examine fetal presentation and position prior to positioning
the cup over the flexion point.
CAUTION: DO NOT USE PRODUCT IF FLEXION POINT IS NOT
ACCESSIBLE.
5. Wipe the scalp as clean as possible.
6. To insert the M-Style Mushroom Cup,
grasp cup with the fingers and fold
edges inward to facilitate insertion
(see Figure 1). Separate the labia
with the other hand. Press the cup
portion downward and inward over the
fourchette to make contact with the
fetal scalp.
Apply the center of the cup over the
flexion point (see Figure 2). The flexion
point can be located by identifying the
posterior fontanelle and then moving
the finger anteriorly along the sagittal
suture approximately 1.2 in. (3 cm). The
sagittal suture should pass under the
middle of the cup.
CAUTION: NEVER APPLY THE CUP
TO ANY PORTION OF THE INFANT'S
FACE.
