Temperature indicating chemotherapy cap

A temperature indicating cap shaped headwear device that is worn on a patient's head while the patient is having an injection-type of chemotherapy treatment. The headwear device has an outer layer of sheet material vertically spaced from an inner layer of sheet material. The outer layer is attached to the inner layer in a quilting pattern that forms individual cells between the outer layer and the inner layer of sheet material. Each of the quilting cells are filled with a temperature indicating material that can be brought to a substantially frozen state causing the material to exhibit a first color. As the material warms to a predetermined higher temperature outside the therapeutic range, the material changes to a second color which provides a visual signal that a new headwear device should be placed on the patients head if further chemotherapy treatment is required.

DESCRIPTION OF THE PREFERRED EMBODIMENT The novel temperature indicating chemotherapy cap will now be described by referring to FIGS. 1 - 6 of the drawings. The chemotherapy cap is generally designated numeral 10 . FIG. 1 is a visual version of what chemotherapy cap 10 might look like. The quilted cells 12 have a distinctive appearance. FIGS. 2 - 6 illustrate a version of what chemotherapy cap 10 looks like from its front end, its rear end, its left side, its right side and what its inner and outer contours would appear like through a longitudinally taken vertical cross section. FIG. 5 is a schematic view showing that chemotherapy cap 10 has a substantially convex outer surface 14 , a substantially concave inner surface 16 , a front edge 18 and a rear edge 20 . FIGS. 3 and 4 are schematic views showing chemotherapy cap 10 also having a top wall surface 24 , a front wall surface 26 , a rear wall surface 28 , a left side wall surface 30 and a right side wall surface 32 . Left side wall surface 30 has a cutout-ear portion 34 and right side wall surface 32 would have a similar cutout-ear portion (not shown). FIG. 6 is a vertical cross sectional view showing a couple of the individual cells 12 . Chemotherapy cap 10 is seen to have a top layer of sheet material 40 that may be plastic, paper or any other suitable material. Bottom layer of sheet material 42 could also be formed of any of the aforementioned materials. The cells are formed by stitches or heat welded seams 50 . The cells 12 have a height H 1 that is in the range of ½-2 inches. Each cell is filled with a coolant material 60 that may be a gel, a powder, or any other type of material that can be frozen and which would have temperature indicating properties. The coolant material would preferably have a predetermined first color in the T 1 -T 2 range wherein T 1 is approximately 28° F. and T 2 is approximately 36° F. When the coolant material 60 warms up to a temperature greater than T 2 it will exhibit a second predetermined color or no color and thus provide a visual signal that a new headwear device should be placed on the patients head if further chemotherapy treatment is to be continued.
