Abstract: A patch for increasing an adhesive strength of a physiological parameter detection device on a skin surface includes a backing and a peelable sheet. The backing is disposed with an adhesive layer having an adhesive surface. The adhesive surface includes a central adhesive portion and an outer adhesive portion, and, upon the central adhesive portion is exposed, the patch is caused to apply a pressure toward the physiological parameter detection device so as to allow the central adhesive portion to be adhered to a top surface of the physiological parameter detection device. The peelable sheet, which is detachably adhered to the adhesive surface for preserving the adhesive surface, includes an inner peelable portion and an outer peelable portion. After the central adhesive portion is exposed, the outer peelable sheet continuously provides a supporting force for the backing so as to allow the backing to be easily and evenly adhered.
