Abstract

A cranial cap dressing for dressing a craniotomy wound comprising a breathable elastic outer layer sized to fit snuggly on a human head of a patient and an absorbent inner layer attached to the breathable elastic outer layer.

First claim

Wherefore, I claim:

1 . A cranial cap dressing for dressing a human craniotomy wound comprising:
a breathable elastic outer layer sized to fit snuggly on a head of a human patient, and an absorbent inner layer attached to the breathable elastic outer layer.

2 . The cranial cap dressing of claim 1 further comprising a plurality of breathing channels in the absorbent inner layer providing a passageway for air through the absorbent inner layer to the breathable elastic outer layer.

3 . The cranial cap dressing of claim 1 further comprising a contact film polymer layer coating on a proximal skin facing surface of the inner layer that reduces the adhesion of the inner layer to the wound.

4 . The cranial cap dressing of claim 3 further comprising a plurality of perforations in the contact film polymer layer coating to allow air and bodily fluids to pass through the contact film polymer layer coating.

5 . The cranial cap dressing of claim 1 further comprising a mechanical fastener along a circumference of the cranial cap dressing, which helps secure the cranial cap dressing on the head of the patient.

6 . The cranial cap dressing of claim 5 , wherein the mechanical fastener is one of a Velcro flap, a button, a snap, a latch, a buckle, a fabric tie, and a string tie.

7 . The cranial cap dressing of claim 5 wherein the mechanical fastener is located at an inferior posterior most portion of the cranial cap dressing.

8 . The cranial cap dressing of claim 5 wherein the mechanical fastener is a string tie and further comprising a string substantially further comprising a substantially non-elastic string extending in a channel around the circumference of the cranial cap dressing.

9 . The cranial cap dressing of claim 1 further wherein an anti-microbial agent is affixed to a proximal surface of the inner layer.

10 . The cranial cap dressing of claim 9 wherein the antimicrobial agent is one of elemental or ionic silver.

11 . The cranial cap dressing of claim 9 wherein the antimicrobial agent is one of silver nitrate and silver sulfadiazine.

12 . The cranial cap dressing of claim 1 further comprising the breathable elastic outer layer having a coefficient of static friction between two pieces of the same material being less than 0.3.

13 . The cranial cap dressing of claim 1 further comprising a proximate breathable layer attached to the inner layer, opposite to the outer layer.

14 . The cranial cap dressing of claim 1 wherein a maximum thickness of the inner layer is greater in an area corresponding to an incision than a maximum thickness of the inner layer in an area spaced from the area corresponding to the incision.

15 . The cranial cap dressing of claim 1 wherein the inner layer is formed as a checkered pattern of absorbent material lining a proximal skin facing surface of the outer layer.

16 . The cranial cap dressing of claim 1 wherein the inner layer is a substantially a continuous layer of absorbent material extending substantially completely across a proximal skin facing surface of the outer layer.

17 . The cranial cap dressing of claim 16 further comprising a plurality of perforations through the inner layer to provide breathing channels for vapor to pass through the inner layer to the outer layer.

18 . The cranial cap dressing of claim 1 further comprising a medical adhesive or gel affixed to a circumference of the cranial cap dressing to help releasably secure the cranial cap dressing to a skin of the patient.

19 . The cranial cap dressing of claim 1 wherein the cranial cap dressing substantially completely covers a cranium of the patient.

20 . The cranial cap dressing of claim 1 further comprising one or more flap that may be folded down to cover incisions that extend below a circumference of the cranial cap dressing.
