Introduction Chapter 1: Introduction

Introduction The Affinity® Three Birthing Bed and Affinity® Four Birthing Bed are intended to be used as a birthing bed within the acute care Labor and Delivery Unit. The Affinity® Three Birthing Bed and Affinity® Four Birthing Bed are a three-motor birthing type bed with multiple articulation features (see “Bed Position” on page 1-21). A variety of options are available including nurse call, air system, night light, auxiliary outlets, and siderail controls. See “Features” on page 1-3 for additional information concerning some of the Affinity® Three Birthing Bed and Affinity® Four Birthing Bed features. NOTE: Any reference in this manual to a side of the bed is from the point of view of a patient lying in the bed on her back. This information appears in the manual wherever it is pertinent.

Operating Precautions Before operating the bed, be sure that you have read and understand in detail the contents of this manual. It is important that you read and strictly adhere to the safety precautions (see “Safety Tips” on page 1-21). For additional operating precautions for the bed and its accessories, refer to the Affinity® Three Birthing Bed and Affinity® Four Birthing Bed User Manual (USR025).

Features The bed incorporates three independent motors to raise and lower the following bed features: • Bed height • Foot section • Head section (The seat section automatically tilts with head section operation.) These functions are governed by P.C. board logic and controlled by the use of the siderail bed controls or an optional hand-held, six-function pendant. Head Section Inclination The bed is mechanized so that the patient or attendant may elevate the head section by pressing a switch. The head up/head down switches are momentary

Introduction Chapter 1: Introduction

contact type switches and are pictorially labeled to indicate their function. The switches are fixed in relation to the head section and within easy access of both the occupant and attendant, regardless of the degree of inclination. Foot Section Inclination The bed is mechanized so that the patient or attendant may elevate the foot section by pressing a switch. The foot up/foot down switches are momentary contact type switches and are pictorially labeled to indicate their function. The switches are fixed in relation to the head section and within easy access of both the occupant and attendant, regardless of the degree of inclination. High Low Sleeping Surface (Hilow) The bed is mechanized so that an attendant can raise or lower the sleeping surface to facilitate examination or bed ingress or egress. The hilow up/down switches are momentary contact type switches and are pictorially labeled to indicate their function. The switches are fixed in relation to the head section and face toward the attendant position only. The hilow up/down switches are not accessible to the occupant. Battery Back-up The bed is designed with battery back-up as a standard feature. The battery allows the hilow, foot, and head motors to be activated from the siderail controls without power being supplied to the bed. In addition, the battery powers the nurse call function, but it does not power any other bed functions. Battery Back-up LED Indicators

• ON = Battery status is operational or when bed is plugged into the appropriate power source. • FLASHING = Battery needs charging. • OFF = Battery is discharged below the level required to run the motors. CAUTION: Remove the battery if the bed will not be in service for extended periods of time. Failure to do so could result in damage to the life of the battery or damage to the bed. Contact the appropriate maintenance personnel. If the battery has been completely discharged, it may take up to 36 hours to recharge to operational status.

Affinity® Three Birthing Bed and Affinity® Four Birthing Bed Service Manual (MAN272 REV 3)

Introduction Chapter 1: Introduction

To ensure the battery is always charged, plug the bed into the appropriate power source whenever possible. If the battery is discharged or unplugged, the bed is still functional when plugged into the appropriate AC receptacle. Disp osal

Power comes from a lead acid battery, which needs to be disposed of properly according to your local regulations. For assistance in disposing of the battery, contact your maintenance technician.

Pb

Auxiliary Outlet (no longer available) The two auxiliary outlets provide electrical power for accessories. Automatic Tilt As the head section is raised, the seat gradually tilts up from 0 to 15 degrees. As the head section is lowered, the seat gradually returns to a flat position. Headboard The headboard is mounted to a metal frame. The headboard has built-in handles, which aid in steering control and increase mobility. The headboard is removable. Docking/Wall Protection Standard roller bumpers, located at the head end of the bed, protect walls and headwall systems from damage. CAUTION: Do not position the head of the bed against a wall or beneath any fixtures. This is to prevent damage due to the arcing motion of the bed while the bed is being raised and lowered. Lockout Control Switch The lockout control switch is located at the head end of the bed on the frame (see figure 1-1 on page 1-6). This control is used to deactivate the patient (inboard) and caregiver (outboard) siderail controls.
