Abstract

Abstract A cap structure for application to the head of a patient to create a cold environment around the scalp portion of the patient during cytotoxic treatment, thereby to reduce alopecia which might arise as a result of the treatment. The cap structure is comprised of a plurality of individual cap structure forming sections or panels with each panel having at least one internal chamber. A substance in each of these internal chambers is capable of being subjected to and achieving a reduced temperature, and of retaining a reduced temperature for a substantial period of time. The cap sections are connected together by flexible members in order to facilitate conforming the cap structure to the patient. The cap structure may include an upper section, two side sections and a rear section, which sections may be fastened together for use, and unfastened for cleaning and/or storage. The cap structure could also be comprised of a unitary member which may be provided with a plurality of panels separated by flexible members.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 176 words
A cap structure for reducing alopecia of a patient undergoing cytotoxic drug treatment by application of said structure to the head of said patient to create a cold environment around a substantial portion of the scalp of the patient, said structure comprising (a) a plurality of fabric panels comprised of a top panel, a back panel and two side panels connected by flexible members, each of said panels having at least one individual substance receiving chamber and a flexible fabric member with fasteners for operatively connecting each of said panels to at least one other panel in order to faciliate conforming said panels into said cap structure to fit closely around the scalp portion of the patient, and (b) a substance in each of the internal chambers in each of said fabric panels capable of being reduced to a low temperature substantially below body temperature and retaining said low temperature for a substantial period thereby to maintain a reduced temperature environment about the scalp portion of the patient for a period before and after said treatment.
Claim 2
Dependent Claim 176 words
A cap structure for reducing alopecia of a patient undergoing cytotoxic drug treatment by application of said structure to the head of said patient to create a cold environment around a substantial portion of the scalp of the patient, said structure comprising (a) a plurality of fabric panels comprised of a top panel, a back panel and two side panels connected by flexible members, each of said panels having at least one individual substance receiving chamber and a flexible fabric member with fasteners for operatively connecting each of said panels to at least one other panel in order to faciliate conforming said panels into said cap structure to fit closely around the scalp portion of the patient, and (b) a substance in each of the internal chambers in each of said fabric panels capable of being reduced to a low temperature substantially below body temperature and retaining said low temperature for a substantial period thereby to maintain a reduced temperature environment about the scalp portion of the patient for a period before and after said treatment.
