CERVICAL COLLAR PERMITTI~G TRACHEOTOM~
Background of the Invention Cervical collars are well-known. See U.S. Patent 3,756,226 dated September 4, 1973. The collar disclosed in said patent is comprised of body halves removably coupled together. At the center of the front half of the collar disclosed in said patent, there is provided a rigid reinforcing support member directly opposite a person's trachea~ Hence, in the event that an emergency tracheotomy is called for, there is no way to have access to the trachea without removing the front half of the collar.
The present invention is direc-ted to a solution of the problem oE how to provide a cervical collar which pro-vides sufficient support so as to restrict the cervical region of a patient at the scene of an accident without hyperextension of the neck and permits a tracheotomy without otherwise interfering with the provision of rigid reinforcing members on the collar halves.
Summarv of the Invention The present invention is directed to a cervical collar which permits a tracheotomy. The cervical collar is com-prised of first and second discrete body halves. Each body half is generally U-shaped and preormed from a soft flexi-ble, light weight foam polymeric material, A strap means is provided for releasably interconnecting the free ends of the halves in overlapping relation. Each half has a rigid ~3~73~
support member fixedly secured thereto adjacent the bight.
The rigid support member on the front half is positioned so as to expose a hole at the bight of the front half fo~
permitting a tracheotomy without interfering with the interconnection between the halves when worn by a patient.
It is an object of the present invention to provide a novel ce~vical colla- which may be used with o- without a stabilizer fo- providing any necessary support and while permitting a tracheotomy without removing the collar.
Other objects will appear hereinafter.
For ~he purpose of illustrating the invention, there is shown in the drawings a form which is presently pre-ferred; it being understood, however, that this invention is not limited to the p-ecise arrangements and instrumen-talities shown.
Figu-e l is a ?erspective view of a person wearing a stabilized cervical collar in accordance with the present invention.
Figure 2 is a perspective view of the stabilized collar shown in Figure l~
Figure 3 is a sectional view taken along the line 3-3 in Figure 2.
Figure 4 is a sectional view taken along the line 4-4 in Figure 3~
Figure 5 is an enlarged perspective view o~ the col-la- shown in figure l without the stabi~izer.
Detailed Description Referring to the drawing in detail, wherein like numerals indicate like elements, there is shown in Figure l a cervical collar designated generally as 10 which may be utilized with or without a stabilizer designated generall~
as 12. Colla- 10 without the stabilizer is shown in figure 5. The collar 10 is comprised of a front half 14 and a rear half 16. Fach collar half is generally U-shaped and preformed from a soft, flexible, light-weight closed . .

cell foam polymeric plastic material. The halves overlap one another as shown more clearly in Figures 2-4 and may have air holes 17 therethrough.
The front half 14 has a chin cavity 18 at the bight.
The chin cavity 18 is preferably covered with a material such as moleskin which is adhesively or otherwise secured to the cavity 18. The front half 14 is provided with a rigid reinforcing support member 20 at the bight. Member 20 has an opening 22 which surrounds a smaller diameter opening 24 in the front half at the bight thereof. Opening 24 has a preferred diameter of about one and one half inches (3~8cm). Opening 24 is positioned so as to be directly opposite the trachea when collar 10 is worn by a patient as shown in Figure 1.
The member 20 is secured to the front half 14 by a plurality of plastic rivets 26. As shown more clearly in Figure 4, the member 20 is arcuate so as to conform to the arcuate surface of the front half 14 adjacent its bight.
As shown in Figures 2 and 4, along one side edge of the member 20, there is provided a slot through which extends one end portion of a strap 30. The strap 30 extends along the front half 14 to the free end thereof wherein the strap is stitched to the front half 14. On other side of the member 20, there is provided a similar slot 32 through which extends one end portion of a strap 34. The other end of the strap 34 is stitched to a free end of the front half 14.
As shown more clearly in Figure 4, at the bight of the rear half 16, there is provided a rigid reinforcing support member 36 attached thereto by a plastic rivet 40.
A strap 38 is also attached to the rear half 16 by said rivet 40.
A strip 42 is attached to one end of the strap 38 and is adapted to overlie a portion of the strap 30 in the assembled relationship of the collar 10. A strip 44 is attached to the other end of strap 38 and is adapted to overlie a portion of strap 34 in the assembled position of ~2~5~
the collar lO. The outer surface o~ straps 30, 34 and the inner surface of the strips 42, 44 have mating structure adapted for releasable engagement. Such mating structure may be of the type which is sold commercially under the trademark VELCRO.
The stabilizer 12 includes a front piece 46 adapted to overlie part of a persons's chest and a rear piece 4~
adapted to overlie a person's back. The front piece and the rear piece are identical except as will be made clear hereinafter. Hence, only the front piece 46 will be des-cribed in detail. Corresponding prime numerals are pro-~ided on the rear piece 48.
The front piece 46 includes a substrate 50 of rigid materially having a generally T-shape. The substrate 50 is preferably made from a rigid polymeric plastic material such as ABS. A liner 52 is adhesively or otherwise secured to the curved innersurface of substrate 50. The liner 52 is preferably made from a closed cell of foam material such as polyethylene so as to have the following attributes:
uniform thickness, non-toxic, low specific gravity of about .04, non-corrosive, and will not burn but will melt. The shape of liner 52 corresponds to the shape of substrate 50.
A connecting member 54 is fixedly connected to the center leg of substrate 50 in any convenient manner such as by plastic rivets 56. The connecting member 54 is pre-ferably made from a softer or more flexible plastic mater-ial than the substrate 50 such as polyethylene.
Member 54 is arcuate at its lower end and channel-shaped at its upper end. Member 54 is telescoped over a downwardly extending extension member 58 on the member 20 until a tongue on member 60 snaps into a slot on member 58.
~ember 60 acts like a hinge and is integral at one end only with the member 54.
It is desirable to removably interconnect the front and rsar pieces 46, 48 to the halves of the collar lO in a manner so that stabilizer 12 is not readily removable by the patient. In this regard, at least one and preferably two plastic rivets 62 are carried by member 54 by way of a flexible string. The rivets 62 are easily pushed and snapped into aligned holes on members 54 and 58. Each rivet prefera~ly is provided with a head having flats on opposite sides thereof and split shanks. The rivets 62 are easily force-fit into the aligned holes by application of finger pressure. However, a tool such as a pair oE pliers is needed to pull out the rivets. Rivets 62 are designed so that they cannot be removed by the patient and should only be removed when authorized by a physician. When the rivets 62 are removed, members 54 and 58 are easily sepa-rated by pulling on the member 60 so as to cause removal of its tongue from the slot in member 58. The channel-shape a-t the upper end of member 54 assures that the tongue of member 60 will be aligned with the mating slot in member 58.
The rear piece 48 is identical with the front piece 46 except as follows. Corresponding elements are provided with corresponding primed numerals. Member 54' is thinner and therefore more flexible than member 54. Greater rigidity is needed on the front peice 46 as compared with the rear piece 48. The upper end of member 54 is remov-ably connected to the reinforcing support member 36 on the rear half 16 in the same manner as described above.
A strap 64 has one end fixedly secured to the sub-strate on the rear piece 48 by a plastic rivet 68. The strap 64 extends through a plastic loop 66 on the front piece 46 and then overlies itself. Juxtaposed surfaces of the strap 64 are provided with adjustable fasteners which are preferably of the VELCRO type.
A strap 70 is similarly provided to interconnect the front and rear pieces 46, 48 on the opposite side from strap 64. One end of strap 70 is fixedly secured to the substrate on the rear piece 48 by a plastic rive-t 74. An intermediate portion of strap 70 extends through a plastic loop 72 on the front piece 46 and then overlies itselfO
~:3~;~5~
Juxtaposed surfaces on strap 70 are provided with adjust-able fasteners as described above.
The collar 10 may be worn by a patient when required due to a particular injury and with advice of a physician.
If the particular injury requires inc-eased stabilization of the collar 10, so as to prevent hyperextending the patient's nec~, the stabilizer 12 is removably connected to the reinforcing members on the front half 14 and rear half 16. When no longer required, the stabilizer 12 may be removed while collar 10 remains on the patient. When an injury requi-es wea-ing of the collar 10 and requi-es a tracheotomy, the trachea is readily accessible through the opening 24. If the opening 24 is too small o~ is not aligned with the trachea, the foam of front half 14 may be readily cut at the scene of an accident and enlarged up to the size of the opening 22. The opening 24 facilitates a tracheotomy without removing the colla- 10 and regardless of whether or or not the stabilizer 12 is removably attached to the collar 10.
Since patients come in different sizes, the collar 10 is preferably made in different sizes such as small, medium and large. All of the rivets described above and shown in drawings are preferably made from plastic whereby a patient may be X-rayed with the collar of the present invention mounted on the patient. There are no metal parts which will show up on X-rays and interfere with evaluation of the X-rays.
An advantage of the collar 10 is that it can facili-tate a life-saving tracheotomy at the scene of an accident.
When additional support is needed, stabilizer 12 can be removably attached to the collar 10 at the scene of the accident or later at a hospital with removing collar 10~
The bight on the front half of the collar has been suffi-ciently reinforced to provide the necessary support without interfering with the access hole needed for tracheotomy.
~L~3~35;~
Thus, there is provided a versatile device for use in an emergency by a paramedic in the field. Colla- 10 pro-vides the required support in the cervical region and can be applied quickly without the necessity of any tools.
The present invention may be embodied in other spe-cific forms without departing from the spirit or essential attributes thereof and accordingly, reference should be made to the appended claims, rather than to the foregoing specification, as indicating the scope of the invention.
