Abstract

A method and system for regulating uterine muscular activity including measuring uterine contraction with an electrical uterine monitor (EUM), and using sensed measurements of the uterine contraction to regulate uterine muscular activity by comparing the sensed measurements to a desired level, wherein the difference between sensed and desired level is used to calculate the level of either manual or automatic application of drugs or electrical signals.

Claims

1. A method for regulating uterine muscular activity comprising:

measuring uterine contraction with an electrical uterine monitor (EUM), said EUM comprising uterine electrical activity sensors that output to a processor, wherein the measuring comprises processing electrical signals of the uterine electrical activity sensors to determine a measured amount of uterine contraction; and

using sensed measurements of the uterine contraction to regulate uterine muscular activity by comparing the sensed measurements to a desired level, said desired level being defined and stored before said measuring, wherein the difference between sensed and desired level is used to calculate the level of either manual or automatic application of a drug or electrical signal, comprising defining the difference between the sensed and the desired levels as an error signal and regulating the uterine muscular activity with a level of control proportional to the error signal.

2. The method according to claim 1, comprising regulating the uterine muscular activity to a level that causes progress in cervix dilatation and fetal head station, but does not cause stress on a fetus.

3. The method according to claim 1, comprising regulating the uterine muscular activity to a level that does not cause pre-term labor.

4. The method according to claim 1, wherein said uterine muscular activity is increased.

5. The method according to claim 4, wherein said uterine muscular activity is increased using electrical stimulation.

6. The method according to claim 4, wherein said uterine muscular activity is increased by administering oxytocin.

7. The method according to claim 1, wherein said uterine muscular activity is decreased.

8. The method according to claim 7, wherein said uterine muscular activity is decreased by administering a tocolytic.

9. The method according to claim 7, wherein said uterine muscular activity is decreased by using interference electrical signals.

10. The method according to claim 1, comprising regulating the uterine muscular activity to treat a non-pregnant woman who experiences contractions.

11. The method according to claim 10, wherein said non-pregnant woman experiences contractions during menstruation.

12. The method according to claim 10, wherein said non-pregnant woman experiences contractions during an IVF procedure.

13. A system for regulating uterine muscular activity comprising:

an electrical uterine monitor (EUM) for measuring uterine contraction, said EUM comprising uterine electrical activity sensors in operative communication with a processor; and

wherein said processor is operative to use sensed measurements of the uterine contraction to regulate uterine muscular activity by comparing the sensed measurements to a desired level, wherein the difference between sensed and desired level is used to calculate the level of either manual or automatic application of a drug or electrical signal, and wherein said processor is operative to define the difference between the sensed and the desired levels as an error signal and to regulate the uterine muscular activity with a level of control proportional to the error signal.

14. The system according to claim 13, wherein said EUM and said processor operate in a control loop with an electrical signal generator or drug delivery system for automatic application of the electrical signal or drug.

15. The system according to claim 13, wherein said uterine muscular activity is increased.

16. The system according to claim 13, wherein said uterine muscular activity is decreased.
