Abstract

The invention herein relates to a kind of safety pin with an attached multi-function thermometer which consists mainly of a temperature display and pulse tone emitting integrated circuit board. The enclosure of the aforesaid integrated circuit board can be fabricated in the shape of various animals or cartoon characters. A safety pin is mounted on the rear side of the enclosure for fastening the device onto the clothing of an infant. Extending from the integrated circuit board is a coiled conductor connected to a threaded seat that is fastened in screw-on fashion to a heat sensor rod contained in a pacifier nipple. As an infant sucks the pacifier nipple, the oral temperature of the infant is measured by the heat sensor rod and the temperature reading is shown via a liquid crystal display on the integrated circuit board. The integrated circuit board also has specially designed temperature setting functions. When the measured temperature exceeds the set temperature, a pulsing tone is produced to indicate that the temperature of the infant is abnormal. Other important objectives include the possibility of connecting the coiled conductor to a thermometer or ear piece to enable temperature reading at a larger number of points on the body, while widening the scope of applications, increasing the multi-function range and raising the added-value of this product--a key secondary objective of the invention herein.

A multi-function thermometer, of which the main components comprise:

a hollow thermoelectric member with a base wherein the base has a through-hole, a heat sensor rod with a heat sensor tip at the upper end as well as a threaded collar and retaining plate, respectively, onto the lower end, and the heat sensor rod is inserted into the through-hole in the thermoelectric member base section, with the threaded collar secured against the underside of the through-hole and the retaining plate secured against the lower interior surface of the thermoelectric member;
a threaded seat that is convex in shape and connected via a coiled conductor to the threaded collar and, the threaded seat is fastened against the underside of the thermoelectric member base section;
an upper cover and a base plate that both enclose an integrated circuit board, and the upper cover has an appropriately placed opening for the insert of the coiled conductor through the upper cover and down to the integrated circuit board, and the upper cover also has a transparent bezel which is aligned with a liquid crystal display that is on the integrated circuit board, and the temperature read by the heat sensor tip is transferred through the coiled conductor and the integrated circuit board to the liquid crystal display, the temperature in numerical representation is viewed through the transparent bezel, furthermore, the integrated circuit board is also capable of processing a range of different electronic signals which are transferred to the liquid crystal display and shown or transferred through the coiled conductor and outputted, mounted on the underside of the base plate is a spring-loaded safety pin and a protruding clasp, and the clasp has an internally formed winding yet contiguous channel consisting of an entry-exit slot and a securing slot which permits the tip of the spring-loaded safety pin to be pushed into the entry-exit slot and guided into the securing slot after being pierced through the clothing of an infant.
