Abstract

A portable panel based on a wireless technology is disclosed. The portable panel detects any pressing of the buttons by the operator and sends out the corresponding radiofrequency (RF) signal to a magnet through wireless protocol. A processer in the magnet receives the RF signal and follows commands to control lights, fans, table motion and other patient setup tasks. The portable panel disclosed herein improves patient comfort as well as throughput of the MR system.

ELECTRONIC FETAL MONITOR

FIELD OF INVENTION

The invention generally relates to fetal monitors and more particularly to a low-cost electronic fetal monitor with wireless transducers.

BACKGROUND OF THE INVENTION

Electronic fetal monitoring (EFM) system is an ultrasound device used for examining the condition of a baby in the uterus by monitoring the heart rate of the baby. Generally, EFM is performed late in pregnancy or continuously during labor to ensure normal delivery of a healthy baby. EFM can be utilized either externally or internally in the womb.

Conventional EFM systems comprise proprietary monitors. Proprietary monitors elevate integrated cost value of the EFM system. Providers of proprietary systems are restricted from reducing costs as they cannot take advantage of bulk production.

Further, telemetry or wireless EFM systems are based on wireless medical telemetry service (WMTS). Figure 1 depicts conventional EFM systems with three different configurations. The WMTS allocates particular frequency band to the wireless EFM system. However, there are numerous instances of conflict in the frequency band among various wireless medical devices which share the same frequency band. WMTS does not provide mechanisms to resolve such frequency band conflicts. One solution to resolve frequency band conflicts is implementation of a sophisticated protocol like frequency hopping in WMTS. However, such protocols disrupt operation of devices from other providers.
