Welcome to the SunTech CT50
Thank you for choosing the SunTech CT50 for accurate monitoring of vital signs. The SunTech CT50 is designed to
be simple and efficient to use and features:
• automatic patient monitoring modes
• averaging of multiple BP readings
• user-programmable monitoring intervals
• audible and visual patient alarms
• connection to EMR system
SunTech CT50 Description and Operation
The SunTech CT50 vital signs monitor can perform automatic blood pressure, pulse oximetry and body temperature
measurements for clinical professionals. For measuring blood pressure, a blood pressure cuff is placed around the
patient’s non-dominant upper arm. The cuff is inflated automatically and blood pressure is measured by the
oscillometric method, which senses pressure waves in the artery when occluded by pressure in the cuff.
Measurement of the frequency of the pressure waves enables heart rate to also be measured. The pulse oximetry
function non-invasively measures the patient’s percent oxygen saturation of arterial hemoglobin using principles of
plethysmography via a SpO2 sensor placed on the patient’s finger. Temperature can be measured using an
oral/axillary/rectal temperature probe containing a thermistor that generates a voltage based on changes in
temperature, and these voltages are recorded by the temperature circuitry. The CT50 is a portable device,
approximately 350 x 245 x 115 mm in size and weighs approximately 3006 g without battery. A color touch screen
allows the user to stop/start a BP measurement, save a set of measurements to memory, control patient alarm
functions, print measurements, and return to the home screen. The touch screen can also be used to select many
different device options. The backlit LCD display shows the user device status and measurement information. A set
of multi-color LED’s on the corner of the front enclosure alerts users to visual alarms. The device uses a
microprocessor with software, which is not accessible to the user. The unit is powered by a single rechargeable
lithium-ion battery at the bottom of the device. Four USB-A port connections can be used to connect optional barcode
scanner or Wi-Fi dongle. An optional internal thermal printer is available. There is also RJ45 Ethernet port for network
connectivity and an RJ11 jack for nurse call connectivity.
Note: For purposes of this manual, the SunTech CT50 (Model 270) may be referred to as “the SunTech CT50,” “the
CT50,” “the device” or “the monitor.”
