Device DescriptionChapter 2
The Auto Syringe AS50 Infusion Pump (hereinafter referred to as “the pump”) is designed
to meet the fluid and drug delivery requirements of today’s changing clinical environment.
It provides accurate, continuous or intermittent infusion of intravenous solutions, drug
solutions, whole blood, and packed red blood cells.
The pump is indicated for infusion via intravenous (IV), intra-arterial (IA), epidural, or
subcutaneous routes of administration. It can be piggybacked into an ongoing infusion
line to deliver secondary solutions automatically, precisely, and economically. Infusion
rates are programmable from 0.01 to 438 mL/hr.
The pump accepts standard disposable syringes from 1 mL to 60 mL in size. A numeric
keypad simplifies programming and makes the pump easy to use. During programming,
the status display prompts the user to enter data about the syringe and the infusion.
While the pump is running, the status display shows information about the infusion.
Safety and effectiveness are reinforced by pre-programmable bolus operation, titration of
a dose without interruption of fluid flow, and easily understood alarm and alert messages.
The pump includes an optional serial communication feature, which provides remote
computer control and monitoring capabilities. A standard 9-pin connector allows an
RS-232 communication link between the pump and the host computer. The “Auto Syringe
AS50 Infusion Pump Programmer’s Manual” describes the use of this feature.
The pump can be custom-configured to select key features that meet specific
requirements. Configurable options include:
● Audio range
● Auto default to previous mode
● Backlight
● Infusion mode selections
● Keypad auto lock
● Maximum infusion rates
● Occlusion pressure sensitivity
● Protocol library
● Remote computer control
● Syringe manufacturer, type and size selections

!
!
● Though the factory-supplied configuration settings are suitable for most therapies, the
personnel.
CAUTION: Do not operate the Auto Syringe AS50 Infusion Pump in the
presence of flammable anesthetics, oxygen-enriched, or explosive
atmospheres.
operator and hospital professionals should verify that the pump’s settings are
appropriate for the clinical application.
● The Protocol Library feature is a configuration option developed to facilitate infusion
programming. Before using a protocol for any specific drug, refer to the full
prescribing information supplied by the drug manufacturer.
● As with all medical electronic equipment, care must be exercised to avoid exposing
this device to powerful sources of electromagnetic interference.
● Do not expose the pump to X-rays, gamma rays, or other ionizing radiation, or to
strong electric or magnetic fields.
● Do not autoclave, steam sterilize, EtO sterilize, or subject the pump or charger to
temperatures in excess of 104° F (40° C).
● Do not use the following chemicals on the device, as they will damage the front panel:
acetone, acetoaldehyde ammonia, benzene, hydroxytoluene, methylene chloride,
and ozone, Do not use cleaners containing n-alkyl dimethyl ethylbenzyl ammonium
chloride unless they appear in the list of recommended cleaners in the Pump
Maintenance section of this manual.
● Do not use hard or sharp objects on the keypad.

Precautions
● If a LINE OCCLUDED alarm occurs, RELIEVE THE RESIDUAL PRESSURE IN THE
SYRINGE BY RELEASING THE PLUNGER DRIVER. If the pressure is not relieved
prior to clearing the occlusion, an unintentional bolus delivery may occur when the
blockage is cleared. Check for kinked tubing, clogged catheter, closed stopcocks, etc.
Check for foreign material preventing movement of the pump mechanism.
● Be sure to PURGE THE SYSTEM OF ALL AIR BEFORE ADMINISTERING ANY
MEDICATION. Failure to follow this normal infusion procedure could precipitate
serious consequences.
● Remember that the volume of fluid contained in the connecting tubing is a residual
amount and cannot be infused. Allow for this extra volume of fluid when initially filling
the syringe.
● In MANUAL SCHEDULE mode, START must be pressed to deliver each dose and
continue the infusion regimen. Pressing any other key silences the audio portion of
DOSE DUE alarm and leaves the pump in Standby state, without initiating a dose
the
delivery.
● Although extreme care has been taken in assembly, component selection, and quality
control during manufacture of the Auto Syringe AS50 Infusion Pump, routine checks
and maintenance procedures must be performed so that patients receiving infusions
can be assured of trouble-free operation.
● Caution must be exercised in the selection of drugs intended to be delivered via any
infusion pump. If the drug contained in the syringe will be exposed to extreme
environmental conditions for prolonged time periods, IT IS IMPORTANT TO SELECT
DRUGS THAT WILL NOT CHANGE PHARMACOLOGICALLY UPON SUCH
EXPOSURE.
● As with all automatic infusion devices, whenever a TOXIC OR DANGEROUS LEVEL
of drug is stored in the reservoir, CONSTANT MONITORING of the infusion is
required.
● CAUTION must be employed to assure that the Auto Syringe AS50 Infusion Pump is
in good working order before putting it into use. If the pump is being operated on
battery power alone, ensure that the battery has been charged as described in this
manual.
● When the pump is first turned on, verify that the Lamp Test is accurate (see “Display,
Battery, and Syringe Sensor Check” on page 75).
● Verify all program data before pressing START.
● Wipe off spills immediately. Do not allow fluid or residues to remain on the pump.
● Repeated incorrect identification of syringe size by Syringe Recognition may signify a
pump fault condition, or that a syringe manufacturer has made a dimensional change.
The pump should be removed from service as soon as possible, so that the problem
can be investigated.
Page 6 Auto Syringe AS50 Infusion Pump Operator’s Manual 07-19-B3-430
● If the Size Override configuration option is enabled, an operator can manually
override the Syringe Recognition feature. Incorrect syringe information may cause
delivery errors.
Special Precautions for Epidural Administration
● Epidural administration of anesthetics is limited to short-term infusion (not to exceed
96 hours) with indwelling catheters specifically indicated for short-term anesthetic
epidural drug delivery.
● Epidural administration of analgesics is limited to use with indwelling catheters
specifically indicated for either short- or long-term analgesic epidural drug delivery.
● To prevent infusion of drugs that are not indicated for epidural use, do not use IV
extension sets that incorporate injection sites during epidural delivery.
● It is strongly recommended that pumps used for epidural drug delivery be clearly
differentiated from pumps used for other routes of administration.
WARNING: Epidural administration of drugs other than those indicated
!
for epidural use could result in serious injury to the patient.

Serial Communication Feature
The pump provides remote control and monitoring capabilities. A standard 9-pin
connector (DB9) allows the connection of an RS-232 cable between the pump and a
computer. The cable allows an operator at a remote computer to control pump operations
and to query the pump for data such as infusion totals, program values, and operational
status. The remote control feature is a configurable option. See the Auto Syringe AS50
Infusion Pump Programmer’s Manual for details.
Page 22 Auto Syringe AS50 Infusion Pump Operator’s Manual 07-19-B3-430
Infusion Modes
The pump provides 18 infusion modes, which fall into two major categories: continuous
and timed infusions. Continuous infusions deliver at a steady, programmed rate. Timed
infusions deliver one or more equal doses according to a programmed schedule. The
infusion modes are briefly described below. For more information see “Detailed
Instructions” on page 27.
Continuous Infusion Modes
mL/hr and mL/min: The rate of infusion is programmed in mL/hr or

The pump automatically displays the effective rate in mL/hr.
the dose is entered in mg/hr, mg/min, mcg/hr or
mcg/min, depending on the mode selected. The pump
automatically displays the effective rate in mL/hr.
mg/kg/hr, mg/kg/min, mcg/kg/hr and mcg/kg/min: The patient's body weight is
entered in kg, the drug concentration is entered in mg/mL,
and the dose is entered in mg/kg/hr, mg/kg/min, mcg/kg/hr
or
mcg/kg/min, depending on the mode selected. The pump
automatically displays the effective rate in mL/hr.
CUSTOM DILUTION: In this mode the pump is programmed for a continuous
infusion and the drug concentration is adjusted for a target
infusion rate and dose. The target rate is entered in mL/hr,
the patient’s body weight is entered in kg, the initial drug
concentration is entered in mg/mL, the target dose is
entered in mcg/kg/min, and the final volume is entered in
mL. The pump calculates and displays the volume of drug
(in mL) to be added to the infusion base solution to produce
a final concentration that achieves the target rate and target
dose. The final concentration is displayed when the infusion
is initiated.
