FIELD OF THE INVENTION
This invention relates to facial support cradles which are adapted for facilitation of prone positioning and support of patients or subjects upon medical examination tables, physical therapy tables, and massage tables.
BACKGROUND OF THE INVENTION
Persons undergoing medical treatment, physical therapy, chiropractic treatment, or massage therapy often lie in a prone or face down position upon a padded table or bench, such table having a head end which is equipped with a facial cradle. During a subject's prone positioned use of such table and facial cradle combination, the subject typically places his or her face directly against upper cushioned surfaces of the facial cradle, the subject viewing therethrough downwardly. Such patients or subjects who lie prone upon such tables often experience anxiety and stress resulting from performance of medical examinations, physical therapy, or chiropractic procedures and manipulations. During prone body positioning, such procedures are typically performed outside of the view of the patient or subject, resulting in stress and anxiety. Conventionally designed and configured table mounted facial cradles tend to aggravate or exacerbate such anxiety and stress by enclosing the subject's face and by acting as blinders which restrict the subject's view to the floor and block peripheral vision.
The instant inventive facial cradle solves or ameliorates the above drawbacks and deficiencies of conventionally configured facial cradles by incorporating specially configured structures which mechanically exert upward contact and pressure against a subject user's facial glabellar point.
BRIEF SUMMARY OF THE INVENTION
Human facial anatomy includes a glabella or glabellar point which is located at the intersection of a subject's sagittal plane and a transverse plane situated at the subject's left and right cranial supra-orbital processes. Anatomy underlying the facial glabellar point comprises the cranium's glabellar suture which is situated immediately posterior to the cranial frontal suture and immediately anterior to the internasal suture. Procerus muscles overlie the cranial glabellar suture, and one or more sub-branches of the ophthalmic branch of the trigeminal nerve typically underlie the glabellar point.
Light percussive contact or tapping exerted against a subject's facial glabellar point is known in the medical arts to produce a glabellar reflex which consists of involuntary closure of eyes. In the acupressure arts, light massaging pressure applied to a subject's glabellar point is understood to effect a lessening of anxiety and to induce relaxation and a state of calm. The instant inventive facial cradle advantageously produces similar contact with and pressure against a patient or subject's facial glabellar point while simultaneously providing face and head support. A cushion component performs such dual head support and glabellar contact functions by providing a laterally extending column section which figuratively corresponds with the column portion of a “E”, and by providing left, right, and medial arms, each such arm having a proximal end fixedly attached to or formed wholly with the E's column section. Distal ends of the “E” cushion's left and right arms perform the facial support function while the “E” cushion's medial arm performs the glabellar point contacting function.
In a preferred embodiment, the “E” cushion's medial or center arm is configured as a “V” having a length or posterior extension which aligns the vertex of the “V” for contact with a patient's glabellar point while anterior aspects of the “E” cushion's column section comfortably support the patient's forehead.
In a preferred embodiment, the “E” cushion of the instant invention is attached to and is supported upon an examination or therapy table in a manner common to conventional facial cradles. In use of the instant inventive facial cradle, a patient or subject may rest his or her face and head against the cushioned upper surfaces of the facial cradle in a manner similar to conventional usage of facial cradles. Simultaneously with resultant face and head support, the inventive “E” cushion's medial arm contacts and presses upwardly against the subject's facial glabellar point advantageously inducing, in the manner of acupressure therapy, a state of calm and lessened anxiety.
Accordingly, objects of the instant invention include the provision of a facial cradle which incorporates structures as described above, and which arranges those structures in relation to each other in manners described above for achievement of the beneficial functions described above.
Other and further objects, benefits, and advantages of the instant invention will become known to those skilled in the art upon review of the Detailed Description which follows, and upon review of the appended drawings.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the drawings, and in particular to FIG. 1, a preferred embodiment of the instant inventive facial cradle is referred to generally by Reference Arrow 1. A primary structural component of the facial cradle 1 comprises an “E” cushion which, similarly with a commonly formed capital letter “E”, includes a column section 2, a left arm (or lower arm from the perspective of an upright letter “E”) 4, a right arm (or upper arm from perspective of the upright letter “E”) 12, and a medial arm 20.
Referring simultaneously to FIGS. 1 and 2, the “E” cushion's left, right, and medial arms 4, 12, and 20 respectively have proximal and distal ends 6 and 8, 14 and 16, and 22 and 24. Such arms' proximal ends 6, 14, and 22 are preferably fixedly attached to or formed wholly with a distal or posterior aspect of the “E” cushion's laterally extending column section 2. Laterally extending dashed lines 23l, 23r, and 23m appearing upon FIG. 2 are respectively situated at the proximal-most ends of the left, right, and medial arms 4, 12, and 20, such lines being representative of the arm's attachments to or whole formations with column 2.
Referring to FIG. 2, the “E” cushion's medial arm 20 preferably is configured to include left and right walls 26 and 28, such walls forming a “V”. The distal-most or posterior ends of the walls 26 and 28 preferably form a vertex 24 whose upper end advantageously functions, as is further explained below, as a glabellar point contacting member. Angle α between such “V” configured walls 26 and 28 is preferably approximately 90°. Suitably, such angle α may alternatively be as acute as a 75° angle, or as obtuse as a 105° angle.
The distal displacement of or extension of the glabellar contacting medial arm end 24 from its column/arm junction 23m is preferably 1¼ inches, such length allowing, referring to FIGS. 3 and 4, the upper and distal aspect of arm 20 to upwardly press against the facial glabellar point 52 of the face of a commonly sized patient or subject 50. Preferably, the elevation of such upper and distal arm aspect is at least as great as that of the column section 2. Suitably, the distal extension of the medial arm 20 may alternatively be as short as inch or as long as 1¾ inches. The patient or subject 50 is representative of prone positioned persons who are medically or chiropractically treated, examined or manipulated, prone positioned persons who receive physical therapy manipulations, and prone positioned persons who receive massage or acupressure therapy. Referring further to FIG. 1, cushioned table or bench 54 is representative of tables utilized for all types of treatments, examination, manipulation, and therapy which are performed upon a prone subject.
Referring simultaneously to FIGS. 1 and 2, the inner aspects of the distal ends of the left and right “E” cushion arms 4 and 12 preferably arcuately and convexly curve inwardly to form left and right cheek supports 10 and 18, the inner aspects or surfaces 9 and 17 of such supports forming and defining therebetween a chin clearance channel 32.
As a result of enhanced medial facial support provided by the medial arm 20, the width of the cushion's central opening 30 may be increased beyond the user's eye spacing, as indicated in FIG. 3. Such opening width enhancement advantageously avoids exertions of pressure by the “E” cushion against the user's facial sinuses.
Referring simultaneously to FIGS. 1, 2, and 4, the interior matrices of the “E” cushion 2,4,12 are preferably composed of elastomeric foam or other common cushioning material, such matrices being denoted by the reference numerals in FIG. 4 having the suffix “f”. Flexible foam interior 2f forms the “E” cushion's column section 2, foam interior 12f forms the “E” cushion's right arm 12, and foam interior 20f forms the medial arm 20. The lateral and vertical dashed line 23m of Drawing FIG. 4 is co-planar with FIG. 2's line 23m, such lines representing the juncture of the “E” cushion's column 2 and medial arm 20.
A rigid base or support plate 46 is provided for underlying support of the “E” cushion, such base 46 preferably having a medial extension 46m which directly underlies and supports the cushion's medial arm 20. The cushioning foam rubber portions of the “E” cushion are preferably fixedly bonded to the upper surface of the rigid base 46 by adhesive bond 3.
Referring to FIGS. 1, 2, and 4, a vinyl or fabric cover 11 is preferably disposed over structures including the “E” cushion 2,4,12 and the rigid base 46, such components being slidably insertable into the cover 11 by means of an insertion seam 13 which is closed by a peripherally extending zipper 15. Cover 11 is intended as representative of flexible plastic coatings which may be directly applied to the cushion's elastomeric foam substrate.
Referring simultaneously to FIGS. 1 and 3, tables or benches such as examination/therapy table 54 are commonly equipped with left and right face cradle supporting brackets or arms 38 and 44, such arms being connected to socket mounted extension arms 40 by means of position angle adjusting joints 42. To facilitate utilization of such arms 38 and 44, the facial cradle 1 preferably comprises support arm mounting means which is capable of alternatively securely attaching the cradle to arms 38 and 44, and enabling removal therefrom. In a preferred embodiment, the support arm mounting means comprise flexible hook and loop pad (commonly “velcro” fasteners) combinations 34,36,48. Such fasteners' flexible hook pads 34 and 36 may be fixedly attached to the undersurface of the “E” cushion or plate 46, while loop pads 48 are correspondingly fixedly attached to upper surfaces of the arms 38 and 44. The depicted support arm mounting means 34,36,48 are representative of other commonly known removable mounting means such as snap fasteners, adhesive bonds, nut and bolt fasteners, screw fasteners, snap ridge and snap channel fasteners, and slide ridge and slide channel fasteners.
In use of the instant invention, referring to FIGS. 1 and 3, a patient or subject 50 may lie prone upon table 54 and may place her face in the position indicated. Upon such facial positioning, the subject 50 may view downwardly through space 30 while her forehead is supported by column section 2 and while her left and right facial cheeks are comfortably supported by cheek supports 10 and 18. The chin clearance channel 32 formed between such supports allows for comfortable extension and positioning of the subject's chin. Simultaneously with the invention's provision of such facial support, the distal end or posterior vertex 24 of the “E” cushion's medial arm 20 advantageously presses upwardly against the subject's glabellar acupressure point 52. Mechanical contact and pressure exerted by arm 20 against the glabellar point 52 beneficially functions in the manner of acupressure therapy to reduce anxiety and to induce a state of calm.
While the principles of the invention have been made clear in the above illustrative embodiment, those skilled in the art may make modifications in the structure, arrangement, portions and components of the invention without departing from those principles. Accordingly, it is intended that the description and drawings be interpreted as illustrative and not in the limiting sense, and that the invention be given a scope at least commensurate with the appended claims.
