IrDA / RS232 / Nurse call Feature
The IrDA (or RS232 / Nurse call optional feature) is a feature on
Alaris® Syringe Pumps that allows the pump to be connected to a
PC or other Alaris® Syringe Pumps. This allows data to be transferred
between the Alaris® Syringe Pump and a PC or another Alaris®
Syringe Pump, (e.g. Data Sets to be uploaded to the pump, Event
Reports to be downloaded from the pump and the pump to be
monitored remotely via a suitable central monitoring or computer
system).
The nurse call interface provides a remote
w
backup to the internal audible alarm. It should
not be relied upon to replace monitoring of
the internal alarm.
Refer to the Technical Service Manual for
further information regarding the RS232
interface. Since it is possible to control the
syringe pump using the RS232 interface at
some distance from the pump and hence
remote from the patient, responsibility for the
control of the pump is vested in the software
run on the computer control system.
The assessment for the suitability of any
software used in the clinical environment to
control or receive data from the pump lies
with the user of the equipment. This software
should include detection of the disconnection
or other failure of the RS232 cable. The
protocol is detailed in the Alaris® Syringe Pump
Communications Protocol (1000PB01088) and
is for general information only.
Any connected
components are required to meet IEC/
EN60950 for data processing and IEC/EN60601
for medical devices. Anyone connecting
additional devices to the signal input or output
is a system configurator and responsible
for meeting the requirements of the system
standard IEC/EN60601-1-1.
