Intrauterine monitoring device

Claim 2

An intrauterine fetal monitoring device to supply medical information including stages of maternal labor and degrees of fetal distress during delivery, the device comprising: a laminate sensor pad, said sensor pad having spatially located therein a controlled wavelength light source(CWLS) for transilluminating a fetus' cutaneous area, a sensor responsive to said CWLS and producing a first signal responding to said transillumination, a transducer for generating a second signal in response to intrauterine pressure during maternal contractions, and a switch means responsive to said second signal for interrupting the first signal during maternal contractions, and a microprocessor, said transducer and said sensor being connected to said microprocessor which delivers the medical information.

Claim 3

The device according to claim 1 wherein said pad has first, second, and third layers, said first layer being a transparent adhesive, said second layer being a transparent film and said third layer being a conforming layer, wherein said CWLS sensor, switch means, and transducer along with interconnecting wires are linearly arranged into said pad between said second and third layers.

Claim 4

The device according to claim 2 wherein said transparent adhesive is a tacky gelatinous mass which is non-fetal irritating, amniotic fluid compatible and removable with water.

Claim 5

A fetal monitoring device for supplying medical information on stages of maternal labor and degrees of fetal distress during delivery, the device comprising a releasable lariat formed from controlled flexural modulus lineal members, said lariat having an inner surface, said device further comprising a controlled wavelength light source(CWLS) for transilluminating a fetus' cutaneous area, a sensor responsive to said CWLS for producing a first signal, a transducer for generating a second signal in response to intrauterine pressure during maternal contractions, and a switch means responsive to said second signal for interrupting the first signal during maternal contractions, said light source, sensor, transducer, and switch means affixed to said inner surface, a microprocessor, said transducer and said sensor being connected to said microprocessor which delivers the medical information, further, said lariat including means for ensnaring a fetus' extremity to bring the CWLS, sensor, and transducer in contact with the fetus' extremity.

Claim 6

A fetal monitoring device for supplying medical information on stages of maternal labor and degrees of fetal distress during delivery, the device comprising a releasable lariat formed from controlled flexural modulus lineal members, said lariat having an inner surface, said device further comprising a controlled wavelength light source(CWLS) for transilluminating a fetus' cutaneous area, a sensor responsive to said CWLS for producing a first signal, a transducer for generating a second signal in response to intrauterine pressure during maternal contractions, and a switch means responsive to said second signal for interrupting the first signal during maternal contractions, said light source, sensor, transducer, and switch means affixed to said inner surface, a microprocessor, said transducer and said sensor being connected to said microprocessor which delivers the medical information, further, said lariat including means for ensnaring a fetus' extremity to bring the CWLS, sensor, and transducer in contact with the fetus' extremity.

Claim 7

A fetal monitoring device for supplying medical information on fetal blood chemistry and stages of labor, the device comprising a scalp monitor coupled with an intrauterine probe, said monitor having a controlled wavelength light source(CWLS) for transilluminating a fetus' cutaneous area, a sensor responsive to said CWLS for producing a first signal, a transducer for generating a second signal in response to intrauterine pressure during maternal contractions, and a switch means responsive to said second signal for interrupting the first signal during maternal contractions, further, said monitor including means for mounting on a fetus' scalp to bring the CWLS, sensor, and transducer in contact with the scalp.

Claim 8

A fetal monitoring device for supplying medical information on fetal blood chemistry and stages of labor, the device comprising a scalp monitor coupled with an intrauterine probe, said monitor having a controlled wavelength light source(CWLS) for transilluminating a fetus' cutaneous area, a sensor responsive to said CWLS for producing a first signal, a transducer for generating a second signal in response to intrauterine pressure during maternal contractions, and a switch means responsive to said second signal for interrupting the first signal during maternal contractions, further, said monitor including means for mounting on a fetus' scalp to bring the CWLS, sensor, and transducer in contact with the scalp.
