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.

Uses existing interfacing
Convenient and familiar handling

Convenient and familiar handling

In addition, it uses the same Avalon CL base station, so you do not need to manage extra interface devices or cabling. In fact, you get the same cableless convenience connecting to the fetal monitor without cable clutter, and the same ease of patient assignment by associating the CL Fetal & Maternal Pod with your base station.
