Abstract

DC60 (26/05/47) This invention involves driving mechanisms for use in dispensing devices. Which includes The casing, which has a spiral, if it is well, is a spiral inside the cylinder, turning the dosage regimen (70) with a spiral that holds the A spiral of such a casing, the drive cylinder (30) that can be loosely welded to Cylinder wear adjustable rotation The single dose (70) and the clutch path (60) is positioned between the single dose swivel (70) and the taper (30). The single dose dose (70) and the throttle (30) are attached to the coupling.The swivel adjusts the given dose per time, and the propeller allows it to rotate in accordance with the housing. When the syringe is rotated, the dose (70) is adjusted and the driver (30) is disengaged. Rotate the wearer, adjust the medication area given each time (70) according to the housing While allowing the drive barrel rotation (30) in line with the casing that does not allow The axial movement of the drive cylinder (30) allows for Has been passed in the longitudinal direction to the near end of Dispensing equipment The invention involved a drive mechanism for use in dispensing devices. Which includes A spiral-shaped casing, if it is well, is a spiral circulating inside the cylinder, rotating, adjusting the given dose per time (70) with a spiral that holds the Spiral of such a frame, the propeller cylinder (30) that can be loosely welded to Cylinder wear adjustable rotation The aforementioned dose (70) and the clutch route (60) positioned between the cylinder. When the coupler with a single dose adjustment dial (70) and the throttle (30) are connected, the coupler (30) is connected. Wear with rotating parts Adjust the amount of drug given at a time and the cylinder will Allows to rotate in accordance with the casing when the cylinder equipped with a gauge with a single dose dose (70) and the throttle (30) are disengaged. Will cause Rotation of the wear cylinder with The injection site adjustment dial (70) is aligned with the casing while not allowing rotation of the propeller cylinder (30) to be in line with the casing which will allow The axial movement of the thrust cylinder (30) so that the force is transferred in the longitudinal direction to the near end of the dosing device.

Claims (3)
