Product overview
The SM-110 is a fetal monitor with a 10.1-inch 1024 x 768 thin high-definition colour TFT screen that tilts through 0 to 135 degrees, so staff can read it from any position around the bed. The laptop-style body protects the screen while the unit is being carried, and the large silicone keys are easy to hit in a hurry.
The ultrasound probe is a 1 MHz wide-beam design with twelve crystals. For twins, an offset display mode separates the two heart rates visually, and a coincidence detection and alarm system warns when the two traces overlap and could be mistaken for one another. A doctor's marker lets staff annotate fetal activity and abnormal events directly on the trace.
Alarms are graded by sound and light. The fetal movement curve is drawn automatically, and monitoring curves and data from the last 24 hours can be stored and replayed. The built-in high-definition thermal printer prints in real time and can reprint earlier sections. TCP/IP networking is standard, so the unit can join a central obstetric station, and a large rechargeable lithium battery is standard. Three parameters are shown as standard - fetal movement, uterine contraction and fetal heart rate; the SM-110 Plus adds SpO₂, pulse rate and blood pressure for six.
