The present invention relates to a prone pregnancy pillow adapted for a pregnant woman to lay on her abdomen in a prone position while providing pelvic elevation, in some instances for allowing a pregnant woman to lay on her abdomen in a prone position while providing pelvic elevation while receiving a chiropractic adjustment to reduce vertebral and or lumbopelvic/sacral subluxation.
Women undergo a great deal of stress during pregnancy, both mental and physical. This stress can result in physical ailments that require attention from a healthcare professional. It is necessary for the woman's health for her chiropractor or medical professional to be able to evaluate and administer specific care while she rests comfortably in a prone position. Due to pregnancy, it is often difficult for a woman to lie comfortably, and sometimes safely, in a prone position while being evaluated and receiving specific care, chiropractic, medical or otherwise.
Physical stress on a pregnant woman can also be caused by the typical weight gain from the pregnancy. The growing fetus tends to project forwardly within the woman's abdomen causing imbalances from the added weight, for which the pregnant woman's body compensates for by posture adjustment. This posture adjustment adversely affects the distribution of weight throughout her body, particularly in the pelvis, sacrum and/or lower back. Prenatal health care professionals suggest that lying face-down with the hips elevated may help relieve stress and pain on the bodily structures affected.
U.S. Pat. No. 4,382,306 to Lickert, discloses a prenatal mattress for supporting the head, abdomen and other portions of the body of a pregnant user lying frontally downwardly thereupon. U.S. Pat. No. 4,944,059 to Wall, discloses a prenatal body support upon which a pregnant woman may lay, that supports the abdomen. U.S. Pat. No. 5,054,142 to Owens, discloses a contoured body cushion that has a plurality of separate cushion segments for supporting various body parts. U.S. Pat. No. 5,185,897 to Van Laanen, discloses an inflatable maternity mattress. U.S. Pat. No. 5,400,449 to Satto, discloses a prone pregnancy cushion.
While the foregoing disclosures may be suitable for the particular identified purposes, or for general use by a pregnant woman, they would not be as suitable for the purposes of hereafter pregnant woman laying in the prone position for being evaluated and/or receiving specific care.
There is a need to provide an improved device to allow the safe and comfortable evaluation and/or specific care of a pregnant woman.
It is an object of the present invention to provide a pregnancy pillow that comfortably and safely supports a pregnant woman while lying face down on a surface, particularly a chiropractic table or bench, so as to allow the pregnant woman to rest comfortably safely while receiving gentle specific chiropractic adjustments to relieve stress upon her lower back, pelvis and/or sacrum.
It is another object of the present invention to provide a pregnancy pillow that will adjust to accommodate women of different sizes, and women in different stages of their pregnancy, such that the pregnancy pillow is a universal device that a chiropractor or other medical professional can utilize for evaluation and/or specific care.
The prone pregnancy pillow of the present invention is directed at supporting a pregnant woman lying face-down or in the prone position while receiving a healthcare assessment or specific care, the prone pregnancy pillow having an early stage segment in the shape of a rectangular quadrilateral trapezoidal prism having a smaller top plane portion and a larger bottom plane portion, wherein the early stage segment has an aperture for receiving the abdomen of a pregnant women in both the smaller top plane portion and the larger bottom plane portion.
In some aspects, the prone pregnancy pillow also has a later stage segment in the shape of a rectangular bilateral trapezoidal prism having a top plane and a bottom plane, wherein the later stage segment has an aperture for receiving the abdomen of a pregnant women in both the smaller top plane portion and the larger bottom plane portion, and a pelvic section that provides the hips of the patient in an elevated position to remove tension on the ligamentous structures supporting the pregnant uterus in the prone position.
In some aspects, the present invention is directed at a method of using a prone pregnancy pillow by a pregnant woman, the prone pregnancy pillow having an early stage segment and a later stage segment, the early stage segment and later stage segment providing pelvic elevation while the pregnant woman lies in the prone position. In some aspects, the early and later stage segments are placed together or stacked on top of each other to accommodate a woman in her later stage of pregnancy allowing for a de-loading of the ligamentous structures of the uterus, pelvis, sacrum and lumbar region. In some aspects, the later stage segment is placed on top of the early stage segment, such that the later stage segment is located between the early stage segment and the pregnant woman when the pregnant woman is lying in the prone position. In some aspects, the early stage segment is placed on top of the later stage segment, such that the early stage segment is located between the later stage segment and the pregnant woman when the pregnant woman is lying in the prone position.
In some aspects, while the pregnant woman is lying in a prone position on the early stage segment, the later stage segment, or the combination of the early and later stage segments, a specific healthcare treatment can be provided to the pregnant woman. In some aspects, the healthcare treatment includes an examination or assessment of the woman's physical health. In some aspects, the healthcare treatment includes the pregnant woman receiving a chiropractic adjustment. In some aspects, the chiropractic adjustment is to reduce vertebral and or lumbopelvic/sacral subluxation.

While laying in the prone position using the early stage segment 20, later stage segment 40, or both the early and later stage segments 20, 40, a healthcare professional can conduct an assessment, evaluation or perform a specific technique on the patient. In some aspects, the pelvic section of the patient is elevated to remove tension on the ligamentous structures supporting the pregnant uterus in the prone position. In some aspects, the patient may receive a chiropractic adjustment. In some aspects, the chiropractic adjustment is to reduce vertebral and or lumbopelvic/sacral subluxation.
In some aspects, the early stage segment 20 may be located on the bottom when stacked with the later stage segment 40, as shown in
While the foregoing description has been described in the context of an abdomen of a pregnant woman, the prone pillow assembly 10 and either of the early or later stage segments 20, 40 can be used for any patient, including patients with larger abdomens or to elevate the hip area of any patient with respect to the chest area, or to elevate the chest area of any patient with respect to the hip area. One of ordinary skill in the art will appreciate that different examination, assessments or techniques may necessitate elevating different areas or regions of the patient.
In some aspects of the present invention, a method of evaluating and/or providing chiropractic care to a patient includes the patient laying in the prone position on top of the early stage segment 20, later stage segment 40, or both the early and later stage segments 20, 40 with the abdomen region of the patient being operably engaged with the with the aperture 25, 45 with the angled distal 35, 55 ends supporting the leg area while the proximal end 37, 57 supports the chest area. In some aspects while laying in this position that includes at least the later stage segment 40, the hips of the patient are provided in a flexed position, such that the hips are elevated respect to the plane of the back of the patient, while the shoulders and head of the patient are located below the hips. While in this position, the chiropractor can provide an evaluation of the patient. While in this position, the chiropractor can also provide an adjustment to the patient. In some aspects, the adjustment provided to the patient while the hips are in the flexed position above the plane of the back and head and shoulders includes the Thompson drop technique, the Webster technique, or a combination of those techniques.
In another embodiment, the early stage segment 20, later stage segment 40, or both together, may be used to hold an infant for examination without rolling off an examination table. In some aspects, the infant would be placed facing upright in the supine position, such that the infant is cradled within the aperture 25, 45. While in the supine position, the infant may be evaluated and/or adjusted. In some aspects, a cranial adjustment may be performed on the infant.
While not shown, the early stage segment 20 and later stage segment 40 may each be contained within separate pillow coverings. Alternatively, both the early and later stage segments 20, 40 may be contained within a pillow covering.
A 30 year old pregnant female patient at 29 weeks presented with the fetus positioned in the frank breech position, which was confirmed by diagnostic ultrasound with the patient's prenatal provider. The patient laid in the prone position on the late stage segment stacked on top of the early stage segment placed on a chiropractic table with her abdomen in the apertures and her hips located at the distal end of the early and later stage, such that the patient's hips were in the flexed position and located above the plane of the patient's back and the shoulders and head.
A chiropractic evaluation was performed on the patient while laying with her hips in the flexed position. The evaluation presented the patient with subluxation present in the SI joints and lumbar spine. While remaining in the prone position on the early and later stage segments, the chiropractic Webster technique was performed on the patient, which is a specific chiropractic sacral analysis and diversified adjustment. The goal of the adjustment is to reduce the effects of sacral subluxation/SI joint dysfunction. In doing so, neuro-biomechanical function in the pelvis is facilitated to reduce strain on the pelvic and sacral ligaments during the adjustment. Sacral subluxation is thought to contribute to difficult labor for the mother (i.e., dystocia), caused by inadequate uterine function, pelvic contraction, and baby mal-presentation. Correction of sacral subluxation may have a positive effect on all of these causes of dystocia. After three separate visits over the course of 1 week using the same Webster technique while the patient laid in the prone position using both the early and late stage pillow in combination with the elevated portion under the pelvis, the subluxations in the pelvis, sacrum and lumbar spine were reduced and holding. The patient returned after an appointment with the patient's prenatal birth provider to confirm fetal position, which was back in proper cephalic presentation position.
A 35 year old pregnant female at 17 weeks presented with lower back and sacral pain with right sided sciatica symptoms, which is about the time most pregnant females start showing physical signs of pregnancy. The patient laid in the prone position on the early stage segment placed on a chiropractic table with her abdomen in the aperture and her hips located at the distal end of the early stage segment. A chiropractic evaluation was performed on the patient while laying in the prone position on the early stage segment. While remaining in the prone position on the early stage segment, the chiropractic Thompson drop technique was performed to reduce the pelvic and vertebral subluxation. This also added extra reassurance and comfort to the mother that the fetus will have extra cushion during the adjustment process.
A 34 year old female 5 months postpartum 34 presented for chiropractic care. The patient laid in the prone position on the early stage segment turned sideways with her breasts located in the aperture and her abdomen and shoulder areas proximate the opposing side ends, respectively. The patient being able to lay in the prone position allowed a more through evaluation and chiropractic adjustment.
An 11-day old female infant presented with latching problems and other difficulties in latching. The infant's mother and father wanting the infant evaluated for cranial subluxation, which often causes latching problems and other difficulties with nursing. The infant was placed in the aperture of the early stage segment in the supine position to cradle the infant for an evaluation. The infant was able to be evaluated and cranial adjustment procedures were done while the infant remained in the supine position within the aperture of the early stage segment.
