摘要：
A medication delivery device comprising: a housing (135, 150) that includes a container holder； a medication container (25) held within the container holder, including the medication container, a cylinder (50, 250, 350) and a plunger (52, 252, 352), the cylinder being manufactured with a light conducting material and extending in an axial direction between a front outlet end (55) and a rear end (57), the piston having at least one peripheral surface region connected, fluid tightly, to an inner surface (70) of a wall (261, 361) of the cylinder to seal the medication (74) in the cylinder in front of the plunger； a feed mechanism (141) within said housing, operable to advance said plunger into said cylinder to dispense the medication from the medication container through said front outlet end； the medication supply device characterized by: a light source (30, 30 ', 162, 230, 330, 440) mounted inside said housing to emit light inside the cylinder wall, so that the cylinder wall it serves as a waveguide that guides the light to run inside in the axial direction； a light detector (35, 35 ', 35 ", 175, 235, 335, 410) mounted inside the vessel holder to detect the reflected light emitted by the light source, runs through the wall of the cylinder that serves as waveguide, and then reflected in the at least one peripheral surface region； and a controller (40) mounted within the housing in communication with said light detector to determine an axial position of the at least one peripheral surface region within the medication container based on the data of said light detector of said reflected reflected light.Un dispositivo de suministro de medicación que comprende: una carcasa (135, 150) que incluye un soporte del recipiente； un recipiente de medicación (25) sujeto dentro del soporte del recipiente, incluyendo el recipiente de medicación, un cilindro (50, 250, 350) y un émbolo (52, 252, 352), estando fabricado el cilindro con un material conductor de luz y que se extiende en u
