Summary of Safety Precautions

SAFETY TIPS AND GUIDELINES

Before operating the Stryker LD304 Birthing Bed, it is important to read and understand all information in this manual. Carefully read and strictly follow the safety guidelines listed on this page. It is important that all users have been trained and educated on the inherent hazards associated with the usage of electric beds.

To ensure its proper use and the safety of patients and staff, the LD304 Birthing Bed has been marked with the following caution and warning labels:

DANGER Explosion Hazard - do not use in the presence of flammable anesthetics. CAUTION This unit is equipped with a hospital grade attachment plug. Grounding reliability can be achieved

only when equipment is connected to equivalent receptacle.

CAUTION Electrical shock hazard. Do not remove cover panels. Refer all servicing to qualified personnel. CAUTION Disconnect the power cord while using the manual hand crank.

WARNINGS

Powered bed mechanisms can cause serious injury. Operate bed only when all persons are clear of the

• mechanisms. To help reduce the number and severity of falls by patients, always leave the bed in the lowest position when the

• patient is unattended. When raising the siderails, listen for the “click” that indicates the siderail has locked in the up position. Pull firmly

• on the siderail to ensure it is locked into position. Siderails are not intended to be a patient restraint device. It is the responsibility of attending medical personnel to determine the degree of restraint and the siderail positioning necessary to ensure a patient will remain safely in bed. The intermediate position should be used only to assist the patient during ingress and egress from the bed. Always apply the caster brakes when a patient is getting on or off the bed. Always keep the caster brakes applied

• when a patient is on the bed (except during transport). Serious injury could result if the bed moves while a patient is getting in or out of bed. After the brake pedal is applied, push on the bed to ensure the brakes are locked. When moving the bed, put the pedal in the steer position. This locks the swivel motion of the right foot end caster and makes the bed easier to move. The instant CPR release is for emergency use only. Before activating the instant CPR, verify all persons and

• equipment are away from the area below and around the Fowler (back rest) section of the bed or serious personal injury or damage to the equipment could occur. Prior to placing weight on the foot section, verify the locking bar has been lowered and locked. The foot section

• locking bar is not designed for use as a grasping bar or other patient assist device. When large spills occur in the area of the circuit boards, 110 volt cables and motors, immediately unplug the bed

• power cord from the power source. Remove the patient from the bed and clean up the fluid. Have maintenance completely check the bed. Fluids can have an affect on operational capabilities of any electrical product. Do not put the bed back into service until it is completely dry and has been thoroughly tested for safe operation. To avoid entanglement, possibly resulting in frayed power cords and risk of electrical shock, wrap the bed power

• cord around the roller bumpers at the head end of the bed during transport. There is a possible fire hazard when using oxygen administering equipment of other than the nasal, mask, or

• 1/2-bed-length tent type. Oxygen tent should not extend below the mattress support platform. Siderails must be kept outside of the oxygen tent. To avoid possible injury or damage to the bed use caution when removing the rue clip and clevis pin. Once the

• rue clip and clevis pin are removed from the motor drive tube, the bed will lean toward the foot end. A hard stop will prevent excessive tipping.

Summary of Safety Precautions

SAFETY TIPS AND GUIDELINES (CONTINUED)

CAUTIONS

Do not steam clean or hose off the bed. Do not immerse any part of the bed. The internal electric parts may

• be damaged by exposure to water. Hand wash all surfaces of the bed with warm water and mild detergent. Dry thoroughly. Inspect the mattress cover after each use. Discontinue use if any cracks or rips are found in the cover which may allow fluids to enter the mattress. Exposure to fluids may cause injury to patient and/or user. Preventative maintenance should be performed at a minimum of annually to ensure all bed features are functioning

• as designed. Close attention should be given to safety features including, but not limited to:

Safety side latching mechanisms,

• Caster braking system,

• Frayed electrical cords and components,

• Leakage current 300 microamperes max,

• Protective earth ground impedance 100 milliohms max,

• No controls or cabling entangled in bed mechanisms,

• All electrical controls return to off or neutral position when released,

• For additional maintenance information, refer to your maintenance manual.

•

Always unplug bed during service or cleaning. When working under the bed with the bed in the high position,

• always place blocks under the litter frame and set the brakes to prevent injury in case the Bed Down switch is accidently pressed. Hand wash all surfaces of the bed with warm water and mild detergent. Dry thoroughly. Do not steam clean,

• pressure wash, hose off or ultrasonically clean. Using these methods of cleaning is not recommended and may void this product’s warranty. Inspect the mattress cover after each use. Discontinue use if any cracks or rips are found in the cover which may allow fluids to enter the mattress. Exposure to fluids may cause injury to patient and/or user. To avoid injury, unplug the bed power cord from the power source before using the manual hand crank.

• The LD304 Birthing Bed is equipped with a hospital grade plug for protection against electric shock hazard. It must

• be plugged directly into a properly grounded three-prong receptacle. Grounding reliability can be achieved only when a hospital grade receptacle is used. To avoid damage, the weight of the I.V. bags should not exceed 40 pounds.

• To avoid damage while transporting the bed, verify the I.V. pole is at a low enough height to allow it to pass safely

• through door openings. I.V. poles should not be used as a bed push/pull device.

• The cleanliness and integrity of both ground chains must be maintained to minimize static build-up and

• discharge. All electronic service parts will be shipped in static shielding bags. Do not open the bags until you have completed

• steps 2 and 3 of the Static Protection Procedure located in the Service Information section. Do not place unprotected circuit boards on the floor. All circuit boards to be returned to Stryker Medical should be shipped in the static shielding bags the new boards were shipped in. Before removing the last motor mounting bolt when replacing a bed lift motor, hold the bed lift motor securely so

• that it will not fall and cause damage. Keep your fingers clear of moving parts when activating the Trend motor to avoid possible injury.

• Release the Foot Down button immediately if the foot support touches the litter frame or damage could occur.

• I.V. poles should not be used as a bed push/pull device.

• The cleanliness and integrity of both ground chains must be maintained to minimize static build-up and

• discharge.

STATIC DISCHARGE PRECAUTIONS

The electronic circuits in the bed are completely protected from static electricity damage only while the bed is assembled. It is extremely important that all service personnel always use adequate static protection when servicing the electronic systems of the bed. Whenever you are touching wires, you should be using static protection.

Static Protection Equipment

The necessary equipment for proper static protection is:

1 static wrist strap; 3M part number 2214 or equivalent,

• 1 grounding plug; 3M part number 61038 or equivalent,

• 1 test lead with a banana plug on one end and an alligator clip on the other; Smith part number N132B699 or

• equivalent.

CAUTION

All electronic service parts will be shipped in static shielding bags. Do not open the bags until you have completed steps 2 and 3 of the following procedure. Do not place unprotected circuit boards on the floor. All circuit boards to be returned to Stryker Medical should be shipped in the static shielding bags the new boards were shipped in.

Static Protection Procedure

Unplug the power cord from the power source.

1. Insert the grounding plug into a properly grounded hospital grade power source. Plug the banana plug of the test

2. lead into the receptacle on the grounding plug. Connect the alligator clip on the other end of the test lead to a ground point on the bed. Place the static control wrist strap on your wrist. Connect the alligator clip at the other end of the wrist strap cord
