Avalon beltless fetal monitoring solution
Cableless fetal and maternal pod with adhesive patch
As a caregiver, you want to sustain your patient’s mobility and comfort. Cableless transducers can help, without sacrificing essential monitoring. However, traditional cableless technology has limitations, such as mothers with a high BMI¹, or those undergoing epidural procedures. This is where the Avalon beltless maternal and fetal monitoring solution provides an alternative.
A change of technology
Abdominal parameters
Parallel measurement
Features
Innovation to give you choice
Instead of conventional ultrasound technology, the beltless solution uses ECG and EMG signals to extract fetal and maternal heart rates and uterine activity from the mother’s abdomen.
Additional labels to avoid confusion
The separate labels (aFHR, aHR, and aToco) document the measurement sources with clarity and consistency.
No need for gaps in documentation
You can avoid breaks in your records, because - rather than disconnecting and connecting - you can use the beltless solution in parallel with cableless Avalon transducers.
