1. A syringe device comprising:
- a syringe body (10;
10′
;
10″
) having a central axis (A), a radially extending syringe flange (14, 14′
) at a proximal end of the syringe body and a needle proximate a distal end of the syringe body,a bearing sleeve (18) receiving the syringe body therein, the sleeve having at least one holding lug (22) co-operating with the syringe body at a proximal end (10A, 10′
A, 10″
A) of the syringe body, in order to hold the said body in relation to the sleeve, andan uneven wedging surface (42;
42′
;

) having alternating radially extending recessed portions (42B;
42′
B;
42″
B), formed by indentations extending in a direction of the central axis (A), and radially extending raised portions (42A;
42′
A;
42″
A), formed by ribs extending in the direction of the central axis (A), the recessed and raised portions alternating in a circumferential direction,wherein;
a distal surface of the wedging surface cooperatively abuts a proximal surface of the syringe flange and the at least one holding lug (22) is insertable in at least one of the recessed portions to prevent rotation of the syringe body (10;
10′
) relative to the bearing sleeve (18).

Abstract
The invention relates to a device comprising a syringe body (10) having an axial direction (A) and a bearing sleeve (18) inside which the body is arranged. The sleeve has at least one holding lug (22) co-operating with the syringe body, at a proximal end (10A) of the latter, in order to hold the body in relation to the sleeve. Said proximal end is fixed to a wedging surface (42) having radial crenulations forming dips (42B) and bumps (42A) and the holding lug is inserted into a dip in order to prevent a relative rotation of the syringe body (10) and the sleeve perpendicularly to the axial direction.

10. A syringe device comprising:
-
a syringe body having a central axis (A), a radially extending syringe flange at a proximal end of the syringe body and a needle proximate a distal end of the syringe body, a wedging part having a proximal flange part defining alternating radially extending recessed portions, formed by indentations extending in a direction of the central axis (A), and radially extending raised portions, formed by ribs extending in the direction of the central axis (A), that alternate in a circumferential direction, the wedging part cooperating with the syringe body such that a distal surface of the flange part cooperatively abuts a proximal surface of the syringe flange, and a bearing sleeve housing the syringe body, the bearing sleeve having at least one holding lug inserted on at least one of the radially extending recessed portions and cooperating with the syringe body at a proximal end of the syringe body to hold the syringe body in relation to the bearing sleeve. - View Dependent Claims (11)
