Abstract

The present disclosure provides methods for decreasing the duration of second stage labor by managing the labor process. In one aspect, a tactile feedback device is positioned adjacent the perianal tissues. A mother'"'"'s labor is monitored for the progression of the baby along the birth canal and adjustments are performed in response to the progression of labor to promote a vaginal childbirth. A perianal support device includes a perianal support member having a pressure surface configured for engagement with tissue adjacent an anal orifice and a pressure detecting system associated with the perianal support member to detect pressure indicative of pressure on the perianal tissue of a patient.

Claims

1. A method of managing child birth labor to reduce a duration of second stage labor, the method comprising:

positioning, by a user, a tactile feedback device comprising a pressure surface proximate perianal tissue of a mother undergoing child birth labor in a manner that provides perianal tactile sensation by the pressure surface to the mother in labor;

monitoring child-birth progression via a pressure detecting system that includes receiving feedback from the pressure detecting system indicative of pressure applied to the perianal tissue by the pressure surface during a child birth labor contraction by the mother; and

responding, by the user, to the feedback from the pressure detecting system by repositioning the tactile feedback device to modify an interaction between the tactile feedback device and the mother in labor and to provide a change in the perianal tactile sensation to the mother in labor.

2. The method of claim 1, wherein the monitoring child-birth progression comprises:

detecting the child birth labor contraction of the mother in labor with the pressure detecting system while the pressure surface is applied against the perianal tissue of the mother in labor; and

tracking a time between contractions of the mother in labor with the pressure detecting system.

3. The method of claim 2, wherein the monitoring child-birth progression of labor further comprises:

inputting, by the user, information indicating the childbirth progression of the mother in labor.

4. The method of claim 3, wherein the information is indicative of at least one of a thickness of a cervix, cervical dilation, and an amount of movement of a child toward a vaginal opening of the mother undergoing child birth labor.

5. The method of claim 2, further comprising:

tracking an overall time of second stage labor as detected by the pressure detecting system.

6. The method of claim 1, further comprising:

applying the tactile feedback device to the mother in labor in a manner that the pressure surface of the tactile feedback device does not provide tactile tissue compression between contractions and does provide tactile tissue compression during a push by the mother in labor.

7. The method of claim 1, wherein the repositioning further comprises:

advancing, by the user, the tactile feedback device inward towards an anus of the mother to increase pressure applied by the pressure surface on the perianal tissue.

8. The method of claim 1, wherein the monitoring further comprises:

monitoring, by the pressure detecting system, the pressure applied to the perianal tissue as the tactile feedback device is being applied to the mother in labor.

9. The method of claim 1, wherein the repositioning further comprises:

moving, by the user, the tactile feedback device to a second tactile position applying less pressure on the perianal tissue.

10. The method of claim 1, further comprising:

changing, by the user, the perianal tactile sensation provided by the pressure surface of the tactile feedback device in response to administration of a numbing medication to the mother in labor.

11. The method of claim 1, further comprising:

alerting, via the pressure detecting system, the mother, the user, or another healthcare provider when contractions generate a change in pressure on the perianal tissue.

12. A method of managing child birth labor to reduce a duration of second stage labor, the method comprising:

applying, by a user, a tactile feedback device comprising a pressure surface to a mother in labor adjacent perianal tissue of the mother in labor in a first tactile position in a manner that provides perianal tactile sensation by the pressure surface to the mother in labor;

securing, by the user, the tactile feedback device to maintain the device in the first tactile position;

monitoring progression of labor via a pressure detecting system that includes receiving feedback from the pressure detecting system indicative of pressure applied to the perianal tissue by the pressure surface during a child birth labor contraction by the mother; and

repositioning, by the user, the tactile feedback device to modify an interaction between the tactile feedback device and the mother in labor in response to feedback from the pressure detecting system.

13. The method of claim 12, wherein the applying further comprises:

applying the tactile feedback device so that the pressure surface does not provide tactile tissue compression between contractions and does provide tactile tissue compression during a push by the mother in labor.

14. The method claim 12, wherein the monitoring progression of labor comprises:

tracking a time between contractions of the mother in labor with the pressure detecting system while the tactile feedback device is adjacent the perianal tissue of the mother in labor.

15. The method claim 14, wherein the monitoring progression of labor further comprises:

inputting, by the user, information indicating the progression of labor, the information being indicative of at least one of a thickness of a cervix, cervical dilation, and an amount of movement of a child toward a vaginal opening of the mother in labor.

16. The method of claim 12, wherein the repositioning further comprises:

moving, by the user, the tactile feedback device to a second tactile position adjacent the perianal tissue in response to changes in the progression of labor.

17. The method of claim 12, wherein the repositioning further comprises:

advancing, by the user, the tactile feedback device inward towards an anus of the mother to increase pressure applied by the pressure surface on the perianal tissue.

18. The method of claim 12, further comprising:

alerting, via the pressure detecting system, the mother, the user, or another healthcare provider when contractions generate a change in pressure on the perianal tissue.

19. A method of managing child birth labor to reduce a duration of second stage labor, the method comprising:

providing a support member having a pressure surface configured to engage perianal tissue of a mother undergoing child birth labor;

positioning, by a user, the pressure surface proximate the perianal tissue of the mother undergoing child birth labor;

monitoring progression of labor via a pressure detecting system detecting pressure on the perianal tissue of the mother undergoing child birth labor applied by the pressure surface against the perianal tissue of the mother undergoing child birth labor; and

repositioning, by the user, the support member to modify an interaction between the support member and the mother in labor in response to pressure detected from the pressure detecting system.

20. The method of claim 19, wherein the monitoring progression of labor comprises:

tracking a time between contractions of the mother in labor with the pressure detecting system while the pressure surface of the support member is engaged with the perianal tissue of the mother in labor.

inputting, by the user, information indicating the progression of labor.

22. The method of claim 21, wherein the information is indicative of at least one of a thickness of a cervix, cervical dilation, and an amount of movement of a child toward a vaginal opening of the mother undergoing child birth labor.

23. The method of claim 19, further comprising:
