Title: Vibrotactile stimulator system for detecting and interrupting apnea in infants
Inventor: EISENFELD LEONARD I
IPC: A61B5/113
Filed: 1995-05-19
Abstract: A vibrotactile stimulator system for detecting and interrupting apnea in premature neonates comprises a multi-sensing monitor for detecting the respiration and other physiological characteristics of the neonate, a vibrotactile sensory stimulator in contact with an extremity of the neonate and a computer interface functionally positioned between the monitor and the vibrotactile stimulator. The interface provides a comparison of the monitored data to preprogrammed individualized standards to determine variations from the standard and provides an intervention output signal to the vibrator. The stimulator includes a cutaneous vibrator engaging a peripheral sensory area of the neonate and being operable at a frequency up to about 400 Hz, but optimally about 260 Hz, to stimulate the neonate and interrupt an apneic episode. The system can include time-delayed, backup, audible and/or visual alarms as well as a graphic display with a pre-apneic printout and cribside or remote manual actuation capability.
