Abstract

An emergency head trauma bandage cap with a detachable strap system and method of use, which, when applied to the head, delivers minimal pressure to control bleeding, doesn'"'"'t compromise cervical spine immobilization, allows for fast and effective application of cooling gel to control intracranial/internal swelling or hot packs to prevent hypothermia in non-trauma situations, doesn'"'"'t come apart during treatment and transport, and doesn'"'"'t require a caregiver to re-wrap the dressing.

Claims

1. A head trauma bandage cap comprising:

a. a flexible cap made of

i. an exterior flexible weather resistant or waterproof material with periphery edges, top and sides defining ear observation openings cut out and adapted to be positioned proximate a patient'"'"'s ears to enable caregivers to observe any fluid discharge from the patient'"'"'s ears and variably secured together with a strapping system in a manner so that the ear observation openings may be varied in size as the strapping system is varied in position, and an opening sized to fit about and cover a forehead/crown, sides, and back of the patient'"'"'s head; and

ii. an interior made of absorbent materials that has a non-adherent wound contact surface, with enough flex when placed on the patient to apply minimal pressure to the patient'"'"'s head to control bleeding without aggravating intracranial pressure and can be hydrated and chilled or frozen to provide an extended duration cooling device; and

b. a stretch and recovery chin strap part of the strapping system allows conformity and flexibility around contours of the face with releasable fasteners affixed to the periphery edges of the flexible cap and structured to secure the chin strap about the patient'"'"'s chin to removably secure the flexible cap to the patient'"'"'s head in a manner to apply minimal pressure to control bleeding without aggravating intracranial pressure in one mode, and loosened and re-attached in another mode to prevent circulation restriction and avoid aggravating intracranial pressure.

2. A head trauma bandage cap according to claim 1, wherein the exterior flexible weather resistant or waterproof material is laminated with layers of film and reinforcing and/or cushioning materials using a permanently flexible adhesive, and/or stitching, which together form a flexible composite structure providing a barrier with stretch and recovery properties to help prevent penetration of bacteria, pathogens or contaminants.

3. A head trauma bandage cap according to claim 2, wherein the exterior flexible weather resistant or waterproof material is a monolithic barrier and the interior has an hydrophobic chemical treatment, which allows air permeability but resists fluid penetration.

4. A head trauma bandage cap according to claim 3, wherein the interior has an hydrophobic chemical treatment, which when placed over the skin, allows moisture or perspiration from skin to escape.

5. A head trauma bandage cap according to claim 2, wherein the interior is made of a flexible fibrous absorbent or superabsorbent polymer (SAP or SAF) component of a soft textile or nonwoven material that can absorb fluids.

6. A head trauma bandage cap according to claim 5, wherein the interior can be hydrated, chilled or frozen to provide an extended duration cooling article.

7. A head trauma bandage cap according to claim 1, including antimicrobials placed in the interior in an additional interior absorbent layer, or on the exterior flexible weather resistant or waterproof material to reduce bacterial populations and infections.

8. A head trauma bandage cap according to claim 7, wherein the antimicrobials are selected from the group comprising traditional silver-ion releasing antimicrobials, quaternary amines and oxidizers, iodine, chlorine or chlorhexidine gluconate (CHG).

9. A head trauma bandage cap according to claim 7, wherein the antimicrobials are 200 ppm of elemental silver embedded in a polyurethane polymer blend.

10. A head trauma bandage cap according to claim 1, wherein the exterior flexible weather resistant or waterproof material comprises a monolithic-breathable film and the interior has an hydrophobic chemical treatment with no holes or direct passages that acts as a bacteria and viral barrier.

11. A head trauma bandage cap according to claim 1, wherein the exterior flexible weather resistant or waterproof material is constructed of polyurethanes, polyolefins, block-copolymers, polyamides, or blends forming a barrier-dressing so exterior particles, fluids and pathogens cannot penetrate from outside toward the patient.

12. A head trauma bandage cap according to claim 1, wherein the releasable fasteners comprise corresponding hook and loop technology.

13. A head trauma bandage cap according to claim 1, wherein the flexible cap is color-coded to indicate severity of the patient'"'"'s injuries in an emergency trauma triage setting.

14. A head trauma bandage cap according to claim 1, wherein ends of the chin strap are Y shaped, and including a hole in the chin strap adapted to be proximate the chin to conform to the contours of the face.

15. A method of making a head trauma bandage cap for covering a patient with a head wound comprising:

a. constructing a flexible cap with

i. an exterior made of a flexible weather resistant or waterproof material with periphery edges, top and sides defining ear observation openings cut out and adapted to be positioned proximate the patient'"'"'s ears to enable caregivers to observe any fluid discharge from the patient'"'"'s ears and variably secured together with a strapping system in a manner so that the ear observation openings may be varied in size as the strapping system is varied in position, and an opening sized to fit about and cover a forehead/crown, sides, and back of a head of the patient, and

ii. an interior made of a sterile absorbent or superabsorbent polymer non-adherent wound contact surface, with enough flex when placed on the patient to apply minimal pressure to the patient'"'"'s head to control bleeding without aggravating intracranial pressure and can be hydrated and chilled or frozen to provide an extended duration cooling device; and

b. affixing a chin strap that is a part of the strapping system with a nonwoven structure processed to form a stretch and recovery or mechanical micro-crepe allowing conformity, elasticity and flexibility around contours of the face with releasable fasteners affixed to the periphery edges of the flexible cap and structured to secure the chin strap about the patient'"'"'s chin to removably secure the flexible cap to the patient'"'"'s head in a manner to apply minimal pressure to control bleeding without aggravating intracranial pressure in one mode, and loosened and re-attached in another mode to prevent circulation restriction and avoid aggravating intracranial pressure.

16. A method of making a head trauma bandage cap according to claim 15, wherein the exterior flexible weather resistant or waterproof material is laminated with layers of film and reinforcing and/or cushioning materials forming a flexible adhesive, which together form a flexible composite structure providing a monolithic barrier film to help prevent penetration of bacteria, pathogens or contaminants.

17. A method of making a head trauma bandage cap according to claim 16, including antimicrobials placed in a sterile non-adherent wound-contact surface, an absorbent layer, or in a waterproof-breathable outer layer to reduce bacterial populations and infections.

18. A method of making head a trauma bandage cap according to claim 17, wherein the antimicrobials are 200 ppm of elemental silver embedded in a polyurethane polymer blend.

19. A method of making a head trauma bandage cap according to claim 18, wherein the releasable fasteners comprise corresponding hook and loop strips.

20. A method of making a head trauma bandage cap according to claim 17, wherein the antimicrobials are selected from the group comprising traditional silver-ion releasing antimicrobials, quaternary amines and oxidizers, iodine, chlorine or chlorhexidine gluconate (CHG).

21. A method of making a head trauma bandage cap according to claim 16, wherein the exterior flexible weather resistant or waterproof material comprises a monolithic barrier, which allows air permeability but resists fluid penetration allowing moisture or perspiration from skin to escape.
