| Abstract: |
Improvements in reuseable, heat exchanging head pieces for cooling or heating substantially the entire hair bearing (scalp) area of the human head; improvements in a blank form for use in the manufacture of such product for the said purposes for filling with reuseable heat exchanging materials; a reuseable, heat exchanging head piece employable with cancer chemotherapy patients in order to cool the scalp zone of the head in order to prevent hair loss during chemotherapy treatment and injections; improved reuseable devices and processes for heat exchanging the human scalp, including such with a variable or adjustable size headband constriction and limited, yet controllable upper head surface of skull surface compression for full, substantially "holiday" free cooling or heating; further improvements in such heat exchanging head pieces wherein the blank form and heat exchanging head pieces are alternatively used or available for use in a one-shot or nonreuseable configuration.

We claim:
1. A heat exchanging head piece for repeatedly cooling or heating substantially the entire scalp (hair bearing) area of the human head, comprising, in combination:
- (1) an elongate, substantially rectangular head band portion adapted to be continuously and circumferentially wrapped around the human head, including the forehead, the temple-ear head side zones and the lower back portion of the cranial vault,
- said head band portion having substantially parallel, spaced apart, opposed upper and lower edges and end edges, the latter positioned substantially at right angles to the former, said head band portion also having inner and outer faces with respect to the head of the user, as well as two free ends at the extremities thereof,
- said head band portion including three elongate, axially series aligned, hollow cells of sealed, liquid tight construction, said cells each containing temperature affectable materials for heat exchange, one of said cells positioned in symmetrical opposition to the crown portion and being at least substantially the width thereof, the other two cells outboard of said first described cell being of substantially equal length to one another and each such being at least substantially free of any connection to the said crown portion,
- (2) a crown portion for such head piece having a forward end and edge secured centrally to the substantial center of the upper edge of the head band portion, side edges extending rearwardly from the said forward edge securement and a free rear end and edge spaced rearwardly from and substantially parallel to said forward edge thereof, said crown portion also having inner and outer faces with respect to the head of the user,
- said crown portion including two elongate, hollow cells of sealed, liquid-tight construction of substantially equal size and substantially congruent form, said cells each containing temperature effectable materials for heat exchange, said cells extending substantially parallel to one another and substantially at right angles to the forward connection of the crown portion to the head band portion,
- (3) means releasably and repeatably engageable between the free ends of the said head band portion adapted to releasably and repeatably secure said free ends together, at least in close adjacency to one another, in adjustable head band size fashion, to form a continuous head band around the head of a human subject,
- said means for securing the head portion end edges together comprising a first elongate length of removably engageable material fixed to the outer face of one end of said head band portions and a second elongate length of removably engageable material fixed in a portion of the length thereof to the inside face of the other end of said head band portion, with a further portion of the latter length thereof extending beyond said end, said first and second lengths removably engageable, one with the other,
- (4) said head band portion being at least sufficiently long that the end edges thereof will at least substantially abut one another, when said head band portion is continuously and circumferentially wrapped around a human head,
- (5) measn adjacent the rear end of said crown portion, on the inner face thereof, adapted to releasably and repeatably secure the crown portion rear end to the outer face of said head band portion substantially 180° away from and opposed to the crown portion forward edge securement to the head band portion, in adjustable crown size fashion,
- the said means at the rear end edge for the crown portion comprising a rearward tab extension of the crown portion of sufficient length and width that such extension is able to overlie, contact and engage a portion of the outer end face of each of the free end portions of the head band portion after the latter have been removably secured to one another,
- the underside of said crown portion rearward tab extension and a portion of the outer end face of each of the head band end portions having means thereon for releasably engaging, one with the other,
- (6) the width of said crown portion cells adjacent the connection of the crown portion to the head band portion being greater than the width of the center cell of the head band portion, and the width of said crown portion cells in the portions thereof spaced farthest away from the head band-crown connection being equal to a substantial portion of the width of the center cell of the head band portion, said crown portion cells not extending into said crown portion rearward tab extension,
- the front connection of said crown portion to said head band portion being substantially the width of the center head band portion cell and in registry therewith,
- (7) means for releasably and repeatably securing the side edges of the crown portion to opposed outer side faces of the head band portion, whereby to form, when: (a) the free ends of the head band portions are releasably secured together, (b) the rearward tab extension of the crown portion is releasably secured to the ends of the head band portion and (c) the side edges of the crown portion are releasably secured to the side faces of the head band portion, a reuseable, size adjustable, substantially continuous contact, scalp contacting head piece for substantially completely and uniformly heat exchanging substantially the entire hair bearing zone of the human scalp,
- the means for securing the side edges of the crown portion to the opposed outer side faces of the head band portion comprising, first, two depending tabs on each of the side edges of the crown portion, said tabs each having removable engaging means on the inner faces thereof and being fixed at one end thereof to a side edge of the crown portion, one of said two tabs depending from the forward side edge of each respective crown portion edge and the other of said tabs depending from each said crown portion side edge at a position substantially intermediate the forward and rearward edges thereof and, second, lengths of removable engaging means fixed to the opposed outer side faces of the head band portion in the entire length of the outer cells thereof, the said depending tabs each being individually adapted to be releasably and adjustably engaged to a chosen portion of one of the outer side faces of the head band portion by the releasable engaging means thereon.
