摘要： A syringe pump has an arm 21 swung against the barrel of the syringe 3. The arm 21 is coupled to a strip mask 30 having a row of transparent apertures 31 to 35 of differing length. The mask 30 extends above a CCD array 40 of sensing elements 41 and below a concave mirror 43, which produces a collimated beam of radiation on the mask from an LED 42. The length of sensing elements 41 exposed to radiation through an aperture 31 to 35 in the mask 30 gives an approximate indication of barrel size; the position of an edge of the aperture gives an accurate indication. The pump compares the barrel size with information relating size to syringe type and produces an indication of syringe type on a display 11.
