However, it is to be understood that the disclosed embodiments are merely exemplary of the present invention, which may be embodied in various systems. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for teaching one skilled in the art to variously practice the present invention.
[0015] All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
[0016] The present invention addresses the problem in the medical OB/GYN field of vaginal delivery in a gravid patient as discussed hereinabove by means of the references mentioned hereinabove and incorporated by reference.
[0017] The present invention provides devices, systems with guides for teaching, understanding, and facilitating natural vaginal birth with the intervention of cervical exams, and the method for health care workers/medical practitioners to perform such cervical exams and to educate the gravid patient/person giving birth to make informed decisions on childbirth and alternate options available to them to choose from to understand complications, if any, and informed decisions to tackle such complications based on real-time analysis and assessment using non-medical interventions. The present invention aims to offer a teaching tool and guide using the disclosed device and method to help everyone to use the same language and the same measurements for exams for uniformity and better and quicker decisions. The present invention is advantageous in that, a health care worker/medical practitioner can carry the disclosed piece of equipment/device since it is portable, and it can be used after a digital exam.
[0018] The following description is in reference to
[0019] As seen in
[0020] As seen in
[0021] It is an aim of the present invention to provide a multifunctional device or guiding tool for health care workers dealing with gravid patients. To that end, the plurality of effacement markings 5 is positioned along a second region 8b of the measurement panel 1, wherein the second region 8b is opposite to the first region 8a across the central aperture 2. In other words, the second region 8b constitutes a second half section of the measurement panel 1, such as a right-side section, that is opposite to the first region 8a. As used here, effacement means the thickness of the cervix. Generally, the cervix needs to get thinner (seen as a larger number of percentages of effacement) before it can dilate (stretch open). Effacement is usually measured in percentages wherein the unit of measurement is 0.5 cm and each 0.5 cm equals 25% effaced. In the disclosure of the present invention in the device, on one side of the device such as the right side of the device, as shown in
[0022] Continuing with the preferred embodiment, the plurality of presentation markings 6 is positioned within the base region 1b. Preferably, the base region 1b is the lower section of the measurement panel 1 that is positioned below the plurality of arcs 3. As used here, the plurality of presentation markings 6 or presentation may mean as to which way the fetal head is directed when compared to the maternal pelvis. This gives the health care worker/medical practitioner the required information about where the head is and how to rotate the maternal pelvis to get the fetal head to move down in the maternal pelvis. In the disclosure of the present invention in the device as shown in
[0023] The measurement of the presentation of the fetal head is in letters labeled as Occiput Posterior referred to as OP, Left Occiput Anterior referred to as LOT, Right Occiput Anterior referred to as ROT, and Occiput Anterior referred to as OA. The letters are representative of where the back (occipital) of the head is compared to the maternal pelvis. For example, the back of the fetal head is to the mother's tailbone is measured as OP or occiput posterior. The suture line would be felt like a vertical line. If the suture line is horizontal, the fetus could be ROT or LOT depending on if the back of the head is to the maternal left or right. As seen in
[0024] A more detailed description of the physical features of the present invention follows. According to the preferred embodiment, and in reference to
[0025] In the preferred embodiment, the present invention further comprises an extended region 11, and an access hole 12. Preferably, the extended region 11 laterally extends from a terminal edge 1c of the measurement panel 1, and the access hole 12 traverses through the extended region 11. As seen in
[0026] A detailed description of a preferred method of operation of the present invention follows. In an embodiment of the present invention, the method for measurement of cervical dilation, presentation of fetal position relative to the maternal pelvis, and/or measurement of effacement of the cervix in a gravid patient by conducting an exam is disclosed, the method comprising the steps of:
[0027] obtaining consent for the exam in the gravid patient after rationalizing and explaining the reason for the exam by a health care worker to the gravid patient;
[0028] laying the gravid patient flat on a surface with a roll or bump under the hips of the gravid patient;
[0029] explaining and assisting the gravid patient into position with heals together and knees apart by the health care worker;
[0030] obtaining consent from the gravid patient again to touch the vaginal area;
[0031] performing an examination of the vaginal area of the gravid patient by the health care worker for the measurement of cervical dilation, presentation of fetal position relative to the maternal pelvis, and/or measurement of effacement of the cervix in a gravid patient,
[0032] wherein the health care worker examines the vaginal area of the gravid patient by first using a gloved non-dominant hand to spread the labia of the gravid patient, then the health care worker gently while using a gloved dominant hand and doused in generous lubrication to insert a pointer finger and a middle finger of said dominant hand in the vagina of the gravid patient, wherein after entering the vagina of the gravid patient, the health care worker makes a peace sign of about 3 cm to 4 cm and feels for the anterior aspect of the vaginal wall and follows the wall backward while allowing the pointer finger and the middle finger to find the cervix and insert them into the cervix of the gravid patient to perform the exam for measurement of the distance of separation between the pointer finger and the middle finger at resting tone, and wherein subsequent measurements are done of the distance of separation between the pointer finger and the middle finger, and said measurements of the distance of separation between the pointer finger and the middle finger are seen as an increase in the measured diameter of the concentric half-circle rings of the device used as a measurement reference of the stretch of the cervix representing cervical dilation in the gravid patient said measured diameter of the concentric half-circle rings of the device providing the measurement of the cervical dilation.
[0033] Accordingly, the guiding and assessment system for cervical examination of gravid patients comprises monitoring how far an examiner's fingers can spread during examination of the gravid patient's cervix and analyzing that information to determine an estimate length to that analysis. Further, the estimate length is compared with the plurality of dilation markings 4 on the measurement panel 1 to assess an accurate dilation value in centimeters. In other words, the health care worker/medical professional measures the stretch of the cervix with their pointer finger and middle finger as per the conventional practice in the field, where the distance by which the said fingers separate indicates how dilated the cervix of the gravid patient is at a given time. Then the health care worker/medical professional takes the separated pointer finger and middle finger at the above-mentioned distance between them and compares it to the reference concentric half-circle rings on the disclosed device of the present invention, the concept is illustrated in
[0034]
[0035] Similarly, in order to measure effacement, the system comprises, monitoring a thickness of the gravid patient's cervix during examination of the gravid patient's cervix and analyzing that information to determine an estimate thickness to that analysis. Further, the estimate thickness is compared to the plurality of effacement markings 5 on the measurement panel 1 to assess an accurate effacement value in percentages. As shown in
[0036] Furthermore, the system may comprise the steps of monitoring an orientation of a suture line of a fetal head through the cervix, during examination of the gravid patient's cervix. This is followed by comparing the suture line's orientation with the plurality of presentation markings to assess which way the fetal head is directed along a maternal pelvis of the gravid patient. More specifically, the presentation may mean as to which way the fetal head is directed when compared to the maternal pelvis. This gives the health care worker/medical practitioner the required information about where the head is and how to rotate the maternal pelvis to get the fetal head to move down in the maternal pelvis. It is important to understand and be able to assess and examine, the direction of the fetal head compared to the maternal pelvis to verify the direction of the fetal head or presentation of the fetal position relative to the maternal pelvis. An illustrative example of a fetal head is provided herein, in
[0037] When assessing and examining the fetal presentation, for the health care worker/medical practitioner, this is an upside-down and backward concept. This is done to see what position (or the way the head is facing) compared to the maternal pelvis as shown in a representative illustration in
