Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
164 words
Device for the delivery-dosing of injectable products comprising a case having reduced dimensions in the interior of which an electromotor with its corresponding feed battery and an electronic programming device or Timer are disposed, the output shaft of the electromotor positioned orthogonally relative to the plunger of a syringe, the outlet tube of which passes through the walls of the case, the plunger at its posterior end fitting into two crossed slots of the head of a rod axially threaded to a cylindrical element located in the posterior zone of the tube of the syringe, which element projects through the nozzle of the syringe forming a portion having a smaller diameter, determining a stepping on which a friction clutch comprised of a bushing provided at its free end with a crown wheel, engages, which wheel constantly meshes with a pinion disposed in the output shaft of the electromotor, the electronic programming device also being provided with two manually operated controls mounted outside the case.
Claim 2
Dependent Claim
