Abstract

DC60 (31/05/47) This invention involves a drive mechanism for use in a dispensing device that includes Cover frame with internal and external thread Connecting rods with a non-circular cross-section and where to get Fastening with Internal thread of the cover frame A unidirectional coupling placed between the cover frame and the swiveling cylinder plunger adjusts the administered dose per time, which is fixed. Do not use a screw and thread. The exterior of the frame and the place Can be rotated in accordance with the frame. Drive cylinder positioned between the cover and the connecting rod. Which can move along Axial but unable to rotate in accordance with the connecting rod and clutch trajectory positioned between the adjusting cylinder A) when the cylinder is rotated, adjust the given dose and the cylinder Wear driver has been disengaged. This clutch will allow the cylinder to be rotated to adjust the amount of drug given at a time. And b) when the cylinder is mounted, adjust the amount of drug administered per time, and The driving cylinder has been paired. Operated by means of such a clutch will This means that it will prevent the rotation of the sprayer adjusting the administered medication area each time corresponding to the sprayer.

Disclaimers (all) that will not appear on the advertisement page: 1. Drive mechanism for use in dosing equipment that includes: a housing (2,2 \ '14,14 \ '14 \' \ '\') with internal thread (26) and external thread (52 , 52 \ '); A connecting rod (32,32 \ ') with a non-circular cross-section, and where it will be fastened using a thread to the internal thread (26) of the frame; Positioned unidirectional coupling (40) coupling is located between the housing (2,14) and the connecting rod (32,32 \ '); Wearable cylinder to adjust the dose (50,50) 50 \ '\' \ '), where it will be confiscated. For example, use the external thread (52,52,) of the shield (2,2 \ '14, 14 \ ', 14 \' \ '\') and that can be rotated. Compared with the cover frame (2,2 \ ', 14,14 \', 14 \ '\' \ '); Prop (60,60 \ '60 \ '\' \ '), designation Location between the frame (2,2 \ ', 14,14 \', 14 \ '\' \ ') and a connecting rod (32,32 \'), where it can move. Can be axially, but cannot be rotated relative to the connecting rod (32,32 \ '), and the clutch trajectory obtained Determination of the position between the driving cylinder (60,60,60 \ '\' \ ') and the dose adjustment dial (50,50 \', 50 \ '\' \ '), where (a) when the cylinder is worn, the dose adjustment is rotated. (50,50 \ ', 50 \' \ '\') and the driving cylinder (60,60 \ ', 60 \' \ '\') is coupled by means of a clutch, the dosing cylinder is rotated. (50,50 \ ', 50 \' \ '\') as compared to the driver's cylinder. (60,60 \ ', 60 \' \ '\') there will be such consent; And (b) when the cylinder is worn, adjust the dose. (50,50 \ ', 50 \' \ '\') and the driving cylinder (60,60 \ ', 60 \' \ '\') is coupled by means of a clutch, the dosing cylinder is rotated. (50,50 \ ', 50 \' \ '\') compared to the muzzle (60,60 \ ', 60 \' \ '\') will be prevented. 2. An assembly for use in an integrated dispensing device.
