Definitions

  • the invention concerns a head and chin rest for face-down operations and is especially directed to the need both for patient comfort and for convenient access by the an- esthesiofogist to the nose and mouth.
  • the patient head In face-down operations with the patient either in a prone or prone sitting position, the patient head is commonly turned to the side even though this puts the cervical spine into an abnormal position and often leaves the patient with a sore neck after a long operation-
  • the sidewise head position constricts the trachea and larynx, thus tending to produce throat soreness when there is a tube in the patient's throat
  • the head When the patient is in a prone position, the head can be positioned face-down on an annular cushion that rests on a support cantilevered from the head end of the operating table.
  • the prone sitting position requires a kneeling attachment to be fastened to the foot of the operating table, and to use an annular cushion would require a hole to be formed in the bed of the operating table.
  • U.S. Patent No. 2,577,177 has "a concave head rest 3 1 to engage the forehead of a patient" (col. 4, lines 52-53) which enables the head to be face-down and also provides-good access to the nose and mouth.
  • U.S. Patent No. 3,289,674 shows in Fig. 1 a similar forehead cushion 108, but both of those head rests leave the chin unsupported, thus producing a lordotic curve in the cervical spine and resulting in problems similar to the consequences of turning the head sidewise.
  • a head rest which is similar except being pivotably supported is shown in "Chick Surgical Table CST Series SE 2001, "a brochure of Chick Surgical Systems, Professional Medical Products, Inc., Greenwood, SC, USA.
  • the present invention concerns a head and chin rest for face-down operations which allows the patient's head, chin and neck to be comfortably supported in a natural position while affording excellent access to the nose and mouth.
  • that of the invention comprises a base and a forehead support pivotably supported by the base.
  • the novel head and chin rest differs from that of the Chick brochure by having
  • chin support is telescopically cantilevered from the forehead support to provide an adjustable spacing between the forehead and chin supports while affording good access to the mouth and nose between and around the rails.
  • the telescopic cantilevering permits the chin rest to be moved in and out to fit heads and faces of various sizes and then locked in position.
  • the forehead support By pivoting the forehead support, the patient's chin can be raised or lowered relative to the forehead.
  • the base should extend beneath the chin support and includes resilient feet allowing it to stand oh a flat operating table surface.
  • each of the forehead and chin supports includes a rigid frame or platform to which a contoured cushion may be removably attached.
  • Each cushion may be a foamed plastic carrying a layer of repositionable pressure-sensitive adhesive on its lower face.
  • the cost of the cushions should be sufficiently low to permit them to be disposable after each operation. While the base and the rigid frames or platforms may be metal for cleanliness, they can be wholly or partly molded plastic at significantly lower cost, thus possibly allowing for economical disposability.
  • the head and chin rest shown in Fig. 1 has a rigid base 10 pivotably supporting a rigid forehead support 12.
  • a clamp 13 cooperates with hidden detents to prevent the forehead support from pivoting until it is unlocked.
  • a rigid chin support 14 is cantilevered from the forehead support 12 by a pair of metal rails 15 which telescopically fit into knurled locking nuts 16 that project from the forehead support 12. The locking nuts 16 permit the rails to be locked at infinitely differing spacings between the forehead and chin supports.
  • Each of the forehead and chin supports has a rigid concave frame or platform 18 formed from sheet metal and into which are fitted disposable contoured cushions 19 and 20, respectively.
  • each concave frame 18 Fixed to the sides of each concave frame 18 are two hooks 26 for securing the straps of an anesthetic mask being worn by the patient
  • the concave frames 18 were formed from stainless steel having a thickness of about one mm, and each of the cushions 19 and 20 was 20-pound polyurethane foam without any covering.
  • the head and chin rest of Fig. 2 has a rigid base 28 on which a rigid forehead support 29 is pivotably mounted at a hinge 30.
  • Fixed to a rigid chin support 32 are a pair of metal rails 34, each of which telescopically fits into a knuried locking nut 36 that projects from the forehead support 29, thus cantifevering the chin support from the forehead support
  • the forehead and chin supports have flat platforms on which are mounted contoured cushions 38 and 40, respectively.
  • Each of the cushions 38 and 40 may be a block of plastic, e.g., polyurethane, foam that has a layer of repositionable pressure-sensitive adhesive by which it is attached to its platform.
  • Fixed to the base 28 is a U-shaped rod 42 which extends beneath the chin support 32.
  • each side of the base 28 Fixed to each side of the base 28 is a soft-metal sector plate or protractor 44 that can be clamped at any point along its arcuate perimeter 45 by a knurled nut 46 projecting from the side of platform of the forehead support 29.
  • a knurled nut 46 projecting from the side of platform of the forehead support 29.
  • a pair of closely spaced, case-hardened steel pins which have been pressed into holes in each side of the platform immediately beneath the knurled nut 46.
  • the tips of the steel pins bite into the inward-facing surface of the softer protractor to guard against slippage under the weight of the patient's head.
  • each steel pin had a length of about 5 mm, a diameter of about 1.5 mm, and a rounded tip which protruded about 0.5 mm beyond the surface of the platform.
  • the head and chin rest of Fig. 2 has a low profile that permits the upper-chest-support cushion to be quite low and hence both inexpensive and laterally stable.
  • the height of the patient's head above the operating table is adjustable by stocking the cushions 38 and 4 0 in various thicknesses.
