Abstract
Described herein are training devices and methods of using the training devices. In particular, disclosed herein are training devices that simulate the experience of using an injection device for administering drugs to patients. The training devices may include lockout mechanisms simulating similar mechanisms in injection devices. Unlike injection devices, the training devices may be resettable, with reset mechanisms that provide for the bypass of the lockout mechanisms, thereby allowing for the reuse of the training device.
Claims20
A training device comprising:
- a first housing;
- a second housing partially housed within the first housing, wherein the second housing comprises a proximal end comprising a plurality of wings and a distal end opposite to the proximal end, wherein each of the plurality of wings comprises a chamfered proximal surface;
- a primary container housed within the second housing;
- a rear cap partially housed within the first housing and the second housing, wherein the rear cap comprises a collar, a plurality of arms, and a plurality of tabs, wherein each of the plurality of arms comprises a chamfered outer surface and each of the plurality of tabs comprises a filleted inner surface;
- and
- a plunger rod partially housed within the first housing and the second housing, wherein the plunger rod comprises a body, a proximal end comprising a pad, and a distal end opposite to the proximal end, and wherein the body comprises a plurality of step protrusions having a plurality of chamfered proximal surfaces and a plurality of chamfered distal surfaces.
A training device comprising:
- a first housing;
- a second housing partially housed within the first housing, wherein the second housing comprises a proximal end comprising a plurality of wings and a distal end opposite to the proximal end, wherein each of the plurality of wings comprises a chamfered proximal surface;
- a primary container housed within the second housing;
- a rear cap partially housed within the first housing and the second housing, wherein the rear cap comprises a collar, a plurality of arms, and a plurality of tabs, wherein each of the plurality of arms comprises a chamfered outer surface and each of the plurality of tabs comprises a filleted inner surface;
- a plunger rod partially housed within the first housing and the second housing, wherein the plunger rod comprises a body, a proximal end comprising a pad, and a distal end opposite to the proximal end, and wherein the body comprises a plurality of step protrusions having a plurality of chamfered proximal surfaces and a plurality of chamfered distal surfaces;
- a lockout mechanism configured to prevent proximal movement of the plunger rod when the plunger rod is in a maximal distal position;
- and
- a reset mechanism configured to allow proximal movement of the plunger rod when the second housing is in a maximal proximal position.
