Method and apparatus providing timed visual images during childbirth
First Claim
1. A medical apparatus for assisting a expectant mother during childbirth comprising:
- a computer having a display monitor;
at least one sensor positioned on a expectant mother to acquire a uterine activity signal from a uterine contraction, said uterine activity signal coupled to said computer;
a software program for operating the computer to determine a change in the uterine activity signal and converting said signal into a vignette image viewable on said display monitor;
wherein said vignette image provides timing of the contraction pattern and visual instruction of when to start and stop pushing during labor by altering said vignette image.

Abstract
Disclosed is an apparatus for providing a visual image timed to coincide with uterine contractions to assist a expectant mother during childbirth labor. The apparatus is particularly useful directed to help those expectant mothers using a regional anesthesia, such as an epidural anesthesia, in the second stage of labor to push effectively. The apparatus consists of a computer system that converts signals obtained from strategically positioned sensors such as a tocodynamometer or intrauterine pressure catheter into biofeedback visual vignettes that are understandable to the expectant mother. The signals are processed into the visual vignettes or a similar pictorial image based upon the pressure of the uterine contractions so that the expectant mother may understand her contraction pattern. This in turn will allow the expectant mother to visually understand when to start and stop pushing during the second stage of labor.

11. A medical apparatus for assisting a expectant mother during childbirth comprising:
-
a computer having a display monitor; at least one internal pressure transducer placed into the uterus for measuring the internal pressure of the uterine contractions on a expectant mother to acquire a uterine activity signal from uterine contraction measurements that are proportional to the amount of pressure that the expectant mother'"'"'s uterine contraction creates, said uterine activity signal coupled to said computer; a software program for operating the computer to determine a change in the uterine activity signal and converting said signal into a vignette image viewable on said display monitor; wherein said vignette image provides timing of the contraction pattern and visual instruction of when to start and stop pushing during labor by a altering said vignette image whereby a base measurement is used to visually depict a vignette in a first position that continues to change until a peak measurement is obtained placing said vignette in a second position. - View Dependent Claims (12, 13, 14, 15, 16, 17)
