Warnings And Cautions; Technical Service; Biomedical Engineering Initial Check-In - Excelsior Medical ESP-60 Manual De Funcionamiento

Warnings and cautions

Avoid any liquids inside the pump. The unit is not waterproof or water resistant.
If a large amount of fluid is spilled on or in the unit, send to the hospital biomedical department prior to
performing an infusion.
Do not sterilize the pump.
Do not use the pump with narcotics, anesthesia, chemotherapy, radioactive pharmaceuticals, fat emulsions or
blood products.
This unit is intended for use under hospital supervision only. Home patient use is allowed only with
instructions provided to the home patient.
Use only with supervision and direction from a licensed pharmacist, nurse or physician.
Do not reuse disposable syringes or microbore extension sets. Both are for Single Use Only. Follow CDC
and or institutional guidelines. Use only tubing with Excelsior specifications.
Battery life will be affected by alarm duration and backpressure.
Biomedical Engineering Initial Check-in Procedure for the Excelsior Syringe Pump
Batteries are already installed at the factory prior to shipment. The unit uses 4 "C" cell alkaline
batteries with the (-) flat side toward the top or into the unit. (+) side is toward the battery cap.
Syringe clamp holder should adequately hold each size of syringe (5/6, 10/12, 20, 30/35, 60) firmly in place.
Pusher arm mechanism should release by pressing the two black levers and move easily up and down the Unit. The
pusher arm mechanism should engage after releasing the black levers.
Visual and audible indicators/alarms
1. Press the START NORMAL SPEED key. The green LED directly above that key should
be flashing and motor operation should be slightly audible.
2. Place the pusher arm mechanism completely at the bottom of travel next to the syringe
barrel clamp holder. The operation should continue until the end of infusion alarm. Both
the flashing red LED and the periodic beep tone should be operative.
3. Press the ALARM key. The audible periodic beep tone should cease, but the flashing red
LED should continue.
4. Press the OFF key and then the START NORMAL SPEED key. The unit should not
restart, but continue to indicate both visual and audible end of syringe alarms. To restart
the pump the pressure must be relieved by moving the pusher block arm from the syringe.
5. Repeat steps 4 and 5 for the two other speeds.
Linear Accuracy is verified up to 670 times per second by an optical encoder. If the motor is not operating within
specifications, all three speed lights and the attention LED will flash simultaneously. To test the accuracy of the pump,
you need to measure the rate of travel of the pusher block mechanism. Measurement of other parameters such as
volume will add additional variables (and potential error) into the test. The following two procedures are recommended.
1. Insert a filled syringe into a pump and compare the infusion time to that indicated in
the "Infusion times and flow rates" chart in the ESP user manual.
Note: Do not include pusher block travel beyond the end of syringe in any test for accuracy of the pump. The time
it takes the pusher block mechanism to travel from the end of the syringe to the trip point that activates the
attention alarm varies from pump to pump.
2 Insert a calibrated dial caliper between the flat surface of the pusher block mechanism and the flat surface at the
end of the syringe plunger. Measure the distance traveled by the pusher block over a period of time. The linear
rate of travel should be equivalent to:
a) 5.48 inches per hour+/- 3% at Normal Speed
b) 2.74 inches per hour+/- 3% at Slow Speed
c) 1.83 inches per hour +/- 3% at XSlow Speed
Occlusion pressure can be tested with the following procedure:
1. Fill a 20ml Monoject syringe with 20ml of water. Connect the micro- bore tubing to
the syringe and prime the line.
2. Connect the micro- bore to a pressure meter and purge any air in the system (use of
a three-way stopcock may be helpful).
3. Insert the syringe into the ESP. Push the desired Start/Speed key to start the
infusion.
4. When the ESP detects an occlusion, the red "Attention" LED will flash
simultaneously with the audible alarm and the motor will stop. Pressure readings
should be in the range of 8psi - 24psi with a nominal value of 16psi.
Note:
a) A new syringe should be used for each test.
b) If another syringe size is used for the test, the tolerance from the nominal pressure PSI listed in the
"Infusion times and flow rates" chart is plus or minus fifty percent (±50%).
c) PSI is determined by dividing the constant occlusion force of 8.0 +/- 1.0 pounds by the cross sectional area
(in square inches) of each syringe. Therefore, a larger cross sectional area (i.e. 60mL syringe) yields a
lower nominal occlusion psi than a smaller cross sectional area (i.e. 12mL syringe).
