Abstract: A safety lancet includes a housing, an actuating unit, a needle unit, a blocking unit and an elastic unit. The housing has a side hole and a front opening. The actuating unit is disposed on an outer surface of the housing. The needle unit, including a needle, a flex pin and a blocking pin, is disposed inside the housing. The needle corresponds to the front opening and the flex pin corresponds to the side hole. One end of the flex pin extends into the side hole to position the needle unit at a first position. The blocking unit is disposed inside the housing and corresponds to the blocking pin to allow the needle unit to forwardly pass through the blocking unit and prevent the needle unit from backwardly passing through the blocking unit.

Abstract: A manufacture method for forming a disposable plate electrode with biological active film is used to cooperate with a biological sensor for analyzing composition and measuring concentration of a test sample according to electric effect resulted from a biochemical reaction. The plate electrode comprises at least an electrode portion for transmission of the electric effect as well as a biological active film that reacts with the test sample chemically or biochemically. The biological active film contains a carrier layer (cellulose, for example) for adsorbing and keeping the biological active substance (enzyme, for example), which, the carrier layer, can change the electrode portion from hydrophobic into hydrophilic and protect the biological active substance against impairment during relatively higher temperature drying process.

Abstract: An improved nipple comprises a grip part, a stop part located at a front end of the grip part, a sucking part coupled with the stop part, at least two pieces of annular body are arranged at a proper position of the sucking part, wherein a clearance is provided between two adjacent bodies. After feeding and when a baby is sucking the nipple, he is holding the sucking part in mouth, meanwhile, his upper and lower incisors are inserted in the clearance, and the pieces of the piece body are pinching the upper and the lower incisors on both sides thereof to remove the remaining lactic acid on the incisors.

Abstract: A biaxial photometer, comprising a mainframe having an optical system secured thereto at one end by a rotary shaft for holding a horizontal sample holder when it is rotated to a horizontal position, or a vertical sample holder when it is rotated to a vertical position. Sample test tube can be inserted in the horizontal sample holder or the vertical sample holder and disposed in a horizontal or vertical position in the passage of the light beam emitted from the optical system for making an assay horizontally or vertically as desired.
