NEEDLELESS DISPOSABLE INJECTOR WITH BENDABLE ELASTIC CASE Russian patent published in 2014 - IPC A61M5/30 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to disposable injectors. An injector contains with a case, where placed are a mechanical energy accumulator, a cylinder-piston unit, a drive rod-stop of a piston and a starting unit, with the drive rod-stop of the piston, which is under resilient impact of a spring, resting against the case with a possibility of detachment. The case of the injector consists of a thin-walled metal sheet component. The metal sheet component has at least two arms. On the free end of each arm there is a holding element or an opening located at an angle. The arms represent elastic cross-beams, which in each case are bent in a z-like way or an s-like way in the middle part to form a support section for the drive rod-stop of the piston. A contact zone, located between the separate support section and the drive pod-stop of the piston forms a pair of a wedge mechanism, forcing the particular arm outside. A latching tongue is located on the arms and a starting element has respective cuts for the latching tongue for the case fixation in the predetermined position.

EFFECT: invention is small in size, has a reduced number of components, is simple in application, its storage and operation are guaranteed.
