Patent CA-2211732-A1 (CA)
Inventor: SAMS BERNARD
IPC: A61M5/32
Filed: 1997-07-30
Abstract: A device for automatically injecting a material into the body is disclosed. The device includes a drive assembly and a disposable assembly including a syringe which is mounted to the drive assembly. The drive assembly includes a drive rod, a driver releasably coupled to the drive rod, and a spring which urges the drive rod towards the syringe assembly. The spring first urges the coupled drive rod and driver along the axis of the device, causing the skin to be penetrated by the needle of the syringe assembly. The drive rod is then decoupled from the driver. The spring continues to urge the drive rod in the axial direction, whereby the drive rod engages a piston in the syringe assembly and causes the displacement of the material therein. A cap is removably mounted to the disposable assembly. Locking members on the cap and disposable assembly prevent removal of the cap until the disposable assembly is moved to the firing position within the drive assembly. A lock release assembly including cooperating elements on the drive assembly and disposable assembly causes disengagement of the locking members upon rotation of the disposable assembly with respect to the drive assembly.

Abstract: A cantilevered shelf system includes a shelf bracket having an upper jaw, a lower jaw extending beyond the upper jaw and a back plate adjoining the upper jaw and the lower jaw, and a shelf having a top face with an engaging surface which contacts the upper jaw as the shelf is mounted into the bracket. The shelf has a bottom face with a rear cam edge and a longitudinal groove forwardly of the cam edge for insertion of a projection on the lower jaw. The distance between the cam edge and the engaging surface is slightly greater than the distance between the upper jaw and the lower jaw, so that the cam edge splays the jaws apart as the shelf is being mounted and the shelf snaps into into a mounted position in which the projectionis seated in the groove. When the shelf is fully mounted the cam edge resists upward displacement of the shelf and the projection prevents forward displacement of the shelf.
