Preventive Maintenance
Only facility-authorized personnel should perform preventive
maintenance on the bed. Preventive maintenance performed by
unauthorized personnel could cause injury or damage.
The Affinity® Three Birthing Bed and Affinity® Four Birthing Beds require
an effective maintenance program. We recommend that you perform semi-
annual preventive maintenance (PM) along with a quarterly battery check and
testing for Joint Commission on Accreditation of Healthcare Organizations
(JCAHO). PM and testing not only meet JCAHO requirements but will help
ensure a long, operative life for the bed. PM will minimize downtime due to
excessive wear.
The following PM schedule (see table 6-2 on page 6-10) guides you through a
normal PM procedure on the bed. During this PM process, check each item on
the schedule, and make the necessary adjustments.
Follow the PM schedule with the corresponding PM checklist (see table 6-3 on
page 6-13). This checklist is designed to keep a running maintenance history
and subsequent repair costs for one bed. However, your facility can modify this
checklist or design another to fit your needs. Two effective ways to reduce
downtime and ensure the patient remains comfortable are keeping close
records and maintaining the bed.
Inspecting the Pivot Point Fasteners
Examine the pivot point fasteners semi-annually. Failure to do so could
cause injury or damage.
1. Inspect the pivot point fasteners (see figure 6-1 on page 6-7).
Depending on what version of bed you have, you may have a pivot point
fastener and block plate, or simply a bracket and bolt.
2. If the pivot point fasteners (A) are finger-loose, or a gap is visible between
the bolt head (B) and the pivot block plate (C), do as follows:
a. Remove the bolt (B or D).
b. Apply Loctite® adhesive to the bolt threads.
