The invention relates to a safe support device for a syringe, said support comprising a support sheath for the body of a syringe, and safety means which comprise an inner sheath suitable for sliding relative to said support sheath between a waiting retracted position, in which said inner sheath is substantially retracted inside said support sheath, and an active protection position, in which said inner sheath projects from said support sheath. The inner sheath has a free end portion formed by a flexible end-piece. The invention also relates to an assembly comprising such a safe support device and a syringe having a body, a piston and a needle disposed at one end of said body.

Needle sheathing device with flexible end-piece for syringe

A safety support device for a syringe comprises a support sheath for the body of the syringe and an inner sheath suitable for sliding relative to the support sheath between a waiting, retracted position and the extended position for protecting the needle of the syringe. The device has means for holding the syringe body relative to the support sheath and retaining means suitable for being activated to retain g the inner sheath in the waiting, retracted position inside the support sheath and for being deactivated by the piston of the syringe to allow the inner sheath to extend into its protective, extended position.

Safety assembly for a syringe

The invention relates to a device comprising a syringe body () having an axial direction (A) and a bearing sleeve () inside which the body is arranged. The sleeve has at least one holding lug () co-operating with the syringe body, at a proximal end (A) of the latter, in order to hold the body in relation to the sleeve. Said proximal end is fixed to a wedging surface () having radial crenulations forming dips (B) and bumps (A) and the holding lug is inserted into a dip in order to prevent a relative rotation of the syringe body () and the sleeve perpendicularly to the axial direction.

The invention relates to a device () for handling an article () such as a coil spring, and to an installation for handling an article. The device () comprises a body () having an internal housing () suitable for containing said article (), said housing () presenting at least one open end (A,B) and a constriction zone () that is suitable in a stable state, in which said constriction zone () presents a reduce dimensions (D) that is reduced in a first direction (X), for retaining said article () inside the body (), and for being deformed to adopt a deformed configuration enabling said article () to be inserted into the housing () or enabling said article () to be extracted from the housing (). The installation includes force-application means for acting on the device to change it between its stable state and its deformed configuration.

Device for handling an article

The invention relates to a safety device comprising a supporting sleeve () for holding the syringe body (), a protective sleeve (), and at least one holding tongue () which is rigidly connected to the protection sleeve and can be held by the supporting sleeve (), in the holding position. The piston comprises a cylindrical skirt (A) that can end up facing a part of the proximal end (A) of the supporting sleeve, at the end of the injection stroke, in order to co-operate with an actuating part (B,B) of the holding tongue, and to release same in such a way as to enable a relative sliding of the protection sleeve and the supporting sleeve in order to protect the neddle. This proximal end part (A) has at least one deflection ramp () that can co-operate with the skirt (A), at the end of the piston stroke, in order to deform the skirt in such a way as to bring part of the skirt of the actuating part (B,B) closer to the holding tongue ().

Method of handling an article

The polisher shuttle serves to polish the inside walls of cylindrical tubes, in particular tubes for medical use. It comprises radial projections that are flexible along the axial direction, suitable for polishing the inside walls of tubes merely by relative movement between the shuttle and the tube, the shuttle passing inside the tube. In a longitudinal section, the sections of the projections form a series of separate undulations that are long and thin in the radial direction. The polishing method made possible by the shuttle is particularly simple, since a single pass of the shuttle can suffice for performing polishing; the method is thus fast and easy to automate, e.g. in a polisher device of the invention.
