DESCRIPTION OF BEST MODE FOR CARRYING
OUT THE INVENTION
The cervical collar of the invention is shown in FIGURE 1 in its unassembled or portable configuration as it would be carried by paramedics in a portable pack or a mobile paramedic unik. The collar comprises an elongated band 10 which is formed of a stiff flexible sheet material such as various plastics, e.g., high and low density polyethylene, polyvinylchloride, acrylonitrile-butadiene~styrene copolymerr polypropylene, etc~ The elongated band 10 has two side portions 12 and 14, an intermediate front portion 16 and a back portion 18. The front portion 16 is o~
greater width than the side portions 12 and 14 and is laterally transposed a substantial distance from the longitudinal axis 20 of band lOo The opposite longitudinal edges 22 and 24 of band 10 are curvilinear with smooth transitions such as 26 and 28 between the side and forward portions. A foam strip 21 is preferably secured to the lower edye 24 of the band 10 by suitable fastening means, e~g., snap fasteners and/or staples~ Cement or other bonding means can also be used. Preferably the foam strip 21 includes a foam pad 53 overlying the inside surface of back 18, as J
~ 2~
shown. This provides additional comfort to the patient. The attachment band 34 is applied over the inside surface of the pad 51 to permit assemhly as shown in FIGURES 3 and 4. The attachment band 34 overlies a short portion 19 of foam pad 53 t as shown in FIG~RE 4. Similarly, the entire inside surface of the Ghin support brace 50 can receive a cushioning pad.
The pads which are used can be foamed plastics such as polyurethane~ Most preferably, the foam strip projects a slight distance past the lower edge 24; as shown to provide maximum cushioning to the patient. A large aperture 30 is preferably provided centrally located in the forward portion to provide access to the patientls throat for an emergency tracheostomyO The hole is optional and may be left out, particularly when the collar is formed of materials having le~ser rigidity such as low density polyethylene.
In its preferred embodiment, the elongated band 10 is asymmetric about its lakeral axis 23 with the back portion 18 of band 10 being integral with one side portion 14, thereby providing the band retaining means to the side of the formed collar/ in a manner hereinafter described. The back portion 18 is preferably of reduced width, sub~tantially as shown, 7,~
and distally carries the collar retaining means, attachment or assembly band 34. The elongated band 10 has a laterally transverse slot 36 adjacent one end, and the attachment or retaining band 34 is passed through this slot, from the inside wall 38 of band 10 and has a free or unattached end portion 35 of approximately equal length to its attached end portion 37. The attachment bandr which preferably is a Velcro fastener, is secured to the elongated band 10 by any suitable means such as rivets 40 and other fasteners.
A cooperative Velcro attachment band 42 is secured to the outside wall of the opposite side portion 12, again with suitable fasteners such as rivets 44 and the like.
The chin support brace 50 is a generally C-shaped plate 52 which has distal apertures 54 and 56 and a central aperture 51. Preferably, one end oE plate 52 is permanently secured to one of the sides 12 of the collar by suitable meansr e.g., a rivet or snap fastener 57. The center of chin support brace 50 is also secured to the collar by snap fastener 55 which extends through apertur2 51 and into an aligned aperture of apendage or tab 13 that projects from edge `~,' ~2~
22 of the collar. The opposite end of the plate 52 is unattached, however suitable attachment means such as a snap fastener 59 is provided whereby the opposite or free end 58 of plate 52 can be secured to the opposite side 14 of the elongated band 10 during assembly of the cervical collar. To this end, a cooperative aperture 60 is provided at a symmetrical position in side 14 relative to the front portion 16 of band 10.
The chi~ support brace 50, as previously mentioned, has a general C-shape with bighk portion 64 of expanded width with an arcuate forward edge 66.
Chin support 50 can be formed of the same, stiff, flexible sheet material as used for elongated band 10 or if desired a sheet material of a preselected stiffness, e.g. ~ one having slightly more pliability~
can be used for greater patient comfort while still providing the necessary immobilization.
Referring now to FIG~RE 2, the assembly of the cervical collar will be describedq As shown in FIGURE
2, the cervical collar is partially assembled; with the chin support brace 50 secured with both of its ~nds attached to ~he opposite sides 12 and 14 of the collar 10. This is accomplished by bowing the front portion 2~
16 and moving the chin support brace to align apertures 56 and 60 and then securing the assembly by inserting the snap fastener 59 through the aligned apertures.
Additionally, the attachment of the chin support brace to ~he opposite sides of the cervical collar in the illustrated manner reinorces the cervical collar and retains it in a partially cylindrical configuration with an arcuate bow 70 to the front portion 16 of the collar 10. In this configuration, the cervical collar is ready for application on the patient.
FIGURE 3 shows the cervical collar in place about a patients' neck 74. The collar is secured in assembly by engagement of band 34 with its cooperative band 42.
In this position, the chin support brace 50 firmly supports the patient~' chin 760 As shown in FrGuRE 4, the attachment band 34 cooperatively engages the cooperative band 42 at two locations; 39 and 41. Generally, the first engagement area 39 is sufficient to retain the assembly, however, a more secure assembly is insured by the engagement area 41 between the end portion 35~ which overlies the en~ lB of band 10, and the cooperative band ~2. This insures that the resiliency of the plastic band 10 does ': ,;
~07;~'7, 1~
not spring the assembly apart. Assembly is also enhanced by the slots 31 (see FIGURE 1) which slightly weaken the end of the collar and permit its deflection before application.
Referring now to FIGURES 5 and 6, there is illustrated the application of the cervical collar to a patient in the supine position. The cervical collar can be readily applied by a paramedic holding the bowed forward portion 16 in one hand 72 while slipping the back portion 18 beneath the patient's neck. The collar can then be guided into place to firmly seat beneath the patient's chin. The back portion is wrapped about the patient's neck, joining the collar into its assembled position with the Eabric attachment band 34 secured to its cooperative band 42 on the outside of side portion 12 of the collar 10.
The cervical collar as thus described is ideally suited for portable or field use by paramedics.
Because the entire collar can be unfolded into a flat position, it can be packed in a portable medical supply kit or stored in a mobile paramedic unit~ The chin support brace is preferably attached with one end permanently secured in a pivot attachment to the collar ~2~
so that it is always present when needed in an emergency. The collar can be readily applied by a single paramedic since the assembly of the chin support brace to both sides of the collar preforms the forward portion of the collar, imparking a bowed configuration thereto, thereby permitting placement o the forward and side portions of the collar about the patient's neck with a single handed operation. Since the collar is asymmetric about its lateral axis with the back portlon integral with one side portion, the collar can be readily applied to supine patients since the collar is assembled at the side rather than at the back.
The cervical collar is intended primarily for temporary use in transporting and preliminary examination of the patient. The collar is formed entirely of plastic or similar material which is transparent to X-rays~ thereby permitting X-ray examination of the patient weariny the collar. The large aperture in the front portion of the collar permits in~ertion of a tube and/or permits paramedics to perform tracheostomies with the collar in place.
Throughout all transporting and examining of the patient, the patient's chin is maintained in an immobilized condition under a slight upward pressure ,, ~ZO~Z7' from ~he chin support brace, all as desired for safe and correct treatment.
