Patent number: 7438719Abstract: A phototherapy system and device is disclosed, including an array of light sources from at least two distinct spectral light regions. The first spectral light region represents the treatment color, and thus is chosen for its phototherapeutic value. For instance, blue light may be the treatment color for hyperbilirubinemia. The second spectral light region represents the balancing color, and is chosen for its ability to mitigate discomfort that may be caused by viewing the treatment color. When blue is the treatment color, yellow has been found to be an effective balancing color.Type: GrantFiled: August 29, 2003Date of Patent: October 21, 2008Assignee: Natus Medical IncorporatedInventors: Dong-Chune Christopher Chung, Abraham Totah, Bryan Flaherty

Patent number: 5247932Abstract: A sensor placement and retention mechanism for use with fetal sensor sites beyond the user's reach are disclosed. The preferred embodiment of this invention is a fetal pulse oximetry sensor having an active face through which a light source and a light detector operate. The sensor includes a handle that facilitates placement of the active face at a sensor site in a preferred region beyond the transcervical region and beyond the reach of the user. A pair of electrodes--one disposed against the fetus' skin and one exposed to the amniotic fluid--are used to confirm that the sensor is firmly in place on the fetus. In an optional sensor retention feature, a self-inflating bladder presses the active face of the sensor against the fetus' skin to optically couple the sensor with the tissue at the sensor site.Type: GrantFiled: October 11, 1991Date of Patent: September 28, 1993Assignee: Nellcor IncorporatedInventors: Christopher Chung, Eric Johansson, Carl Ritson, Paul D.
