Abstract

A fever detecting wrist band device comprises a flexible band and a fever detection device attached to the flexible band. The fever detection device comprises a thermochromic liquid crystal (TLC) material, which can change colors corresponding to a set of temperature ranges, encased in a transparent casing. The transparent casing has a thin bottom section to allow the TLC material to gather body heat when the wrist band is worn by a user and the bottom section comes in contact with the skin of the user. The transparent casing also insulates the TLC material from all sides which are not in contact with the skin of the user so that surrounding temperature of a user does not affect the color change of the TLC material. When the user wears the fever detecting wrist band device, the TLC material might change color indicating a higher body temperature of the user which in turn could indicate that either the user has a fever or the user might have a fever soon if not treated immediately.

Claims

1. A fever detection device comprising:

a thermochromic liquid crystal material;

a casing encasing the thermochromic liquid crystal material and having a bottom section capable of allowing heat transfer from a user to the thermochromic liquid crystal material when the bottom section is in contact with the skin of the user;

a cover, wherein the cover may selectively be positioned in a protective position wherein the cover insulates the bottom section from heat transfer from the user and an exposed position wherein the bottom section is exposed such that the bottom section is capable of being placed in contact with the skin of the user;

an attachment device, wherein the attachment device comprises a wristband that allows for the fever detection device to be removably attached to the user; and

wherein the thermochromic liquid crystal material changes color to a predetermined color in response to a body temperature of the user.

2. The fever detection device of claim 1, wherein the wristband comprises a flexible material.

3. The fever detection device of claim 1, wherein the wristband comprises an outer cover of a material durable enough to withstand climatic conditions, bodily fluids of the user, and wear and tear due to daily use by the user.
