摘要： A syringe pump has a drive mechanism 7 for moving the plunger 35 of a syringe 3 along a barrel 30. Ears 33 at the rear of the barrel 30 engage against a wall 32 on the pump and an L shape clamp arm 44 is urged against the ears by a spring 49. The clamp arm 44 is mounted about an axis at right-angles to the syringe 3 and is articulated at a point 45 along its length. A lever 52 having a flag 53 at one end is pivoted about a horizontal axis by movement of the arm and moves relative to an optical sensor 54 so that the output of the sensor indicates whether the syringe 3 is correctly loaded in the pump. The clamp arm 44 is rotated away from the barrel 30 by the drive mechanism during loading of the syringe 3.

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.

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).
