FR2635686A1 - Collar for protecting fingers against puncture by a syringe needle - Google Patents

Abstract

The present invention relates to a needle cap disc/collar, which may or may not be solidly attached to the cap, preventing any risk of puncture of the hands of the operator when putting the cap back on the needle, which might lead to injury or infection of the operator if the needle is contaminated.

Description

The present invention relates to a protective means intended to protect the fingers of the manipulator against any risk of puncture of the medical injection needle when replacing the latter in
Hood.

 In general, the practitioner holds the assembly - syringe-needle - in one hand and the needle cap in the other and during the introduction of the needle in the cap, the end of the needle can prick the hands of the operator, which could cause injury or contamination to the operator if the needle is dirty.

 The protection system consists of a flange disc (2) arranged perpendicular to the axis of the needle cap (1) (fig. 1).

 The disc t2) can be placed at any height of the cap (1), from the orifice (16) of penetration of the needle (5) to the other end (11) of the cap.

 This protection system can be either dependent and therefore integral with the cap (fig. 15) or independent and therefore removable (fig. Z - fig. 1).

 This disc-collar protection means (2) can be attached directly to each needle protection cap (1) or can be detachable from the cap and re-usable.

Removable collar, independent of the cap
This protection system is composed of a simple disc (2) having a central lumen (21) allowing the fitting of the disc t2) on the cap (1) (fig. 1). The purpose of this disc t2) is to protect the hands of the manipulator during the introduction of the needle (5) into the cap (1).

 This disc-flange protection system allows simple and compact packaging in its packaging.

 This disc-flange protection system can be adapted to commercially available needle caps; the diameter of the light (21) of the disc (2) corresponding to the external diameter of the needle caps (1) the variation of the diameter of the light (21) allowing the disc t2) to be fixed at the desired height on the cap d 'needle (1).

 This removable disc-collar system allows its reuse and therefore a low economic cost.

Removable disc-collar variants, independent of the cap
A variant: the light (21) of the disc (2) is extended by a sleeve ta, adapting to the external surface of the cap (1); this sleeve t3) stabilizes the disc (2) relative to the cap (1). This sleeve can be cylindrical, conical, allowing by friction a coaptation of the cap (1) with the disc (2) and its sleeve (3).

 The sleeve t3) allows a better grip of the disc-cap assembly (Figure 2).

 - According to a variant (FIG. 3), the internal surface (7) of the flaring of the flange (2) is of conical shape facing towards the inside of the cap (1) so as to guide the tip of the 'needle (5) when introduced into the cap (1).

 - In all variants of the collar, the sleeve (3) can be provided at its orifice (16) with a funnel-shaped opening (8) to guide the penetration of the needle (5) into the cap (1 ) figure 4).

 - According to another variant (FIG. 5), the external surface (9) of the flare of the flange (2) is of conical shape turned towards the outside of the cap (1) so as to protect the fingers of the manipulator during The introduction of the needle (3) in the cap (1).

 - In another variant, the circumference of the collar may have a strip or return <10) of a shape that is oriented towards the closed end (11) of the cap (allowing the covering of the end of the fingers of the manipulator : Figure 6) or towards the needle penetration orifice (16) (allowing complete limitation of the sliding of the needle outside the flange (2): Figure 6).

- According to another variant (Figures 7 and 8), the flange (Z) is pro
Loin by a flat portion (12) or forming a portion of cylinder directed towards
The part opposite the closed end (11) of the cap (1); this last part serves as a guide for the introduction of the needle t5) into the cap (1) by sliding
Along the body of the syringe (6). The cap (1) fits onto the sleeve (3).

 This system allows a double protection of the fingers of the manipulator by gripping the cap (1) behind the collar (2) or by gripping the cap (1) (fitted on the sleeve - (3) of the collar) by the guide ( 12) at a distance from the end of the needle (5).

Guide sliding <12) Along the body of the syringe (6) allows
The safe repositioning of the needle (5) inside the cap (1) fitted onto the sleeve (3).

 - According to another variant having a double cap (1) and (13) (Figure 9), cap at each of the ends of the needle (5) example dental needle. Any flange system (2) previously described is provided on each cap (1) and (13) by fitting the cap (1) with the sleeve (3).

 IT IS POSSIBLE TO CONSIDER ANY ACCESSORIES USING THE FLANGING SYSTEM (2) AND THE VARIATIONS CITED EITHER BY A RING, HALF-RING SYSTEM OR ANY VARIANT SYSTEM USING THE FLANGING (2) AND GIVING THE CAP (1) , the flange (2) becoming integral with the accessory, for example the gripping overcap (14) (FIG. 10).

The disc is locked on the cap by a Starlight (17) or slotted cross (18) disc (2) light system or any form of cutout.
Light (Figures II and 12).

 The flange-disc has many geometric shapes of collar (2) giving satisfaction in particular Oval, octagonal, circular shapes ...

 --- The polygonal or oblong shapes of the flanges thus prevent, by their flat part, the displacement of the cap (1) by rolling on any support.

The outside diameter of the flared flange (2) is sufficient
Important to protect part of the manipulator's fingers.

 The shoulder of the collar (2) relative to the external surface of the sleeve (3) or of the cap (1) is greater than or equal to 3 mm.

 The object of your present invention is made of a material sufficiently resistant to the puncture of the tip of the needle (5).

 The materials commonly used in the manufacture of caps (1) (plastics and derivatives) are entirely satisfactory.

 It should be noted that, in the case where the collar (2) has a strip or return (10) (FIG. 5), the material constituting the collar (2) can be made of a very flexible material which can be folded up in a package. so as to occupy as little space as possible.

 The flange system (2) with or without a sleeve (3) can be made of other rigid materials, such as: plastic materials, metal, stainless steel ...

- the collar (2> may include notches corresponding to
The absence of digital pulp during handling (Figures 17 and 18).

 - The collar (2) can be discontinuous.

 - The protection of the digital pulp can be ensured only by a part of a collar (2).

 - According to another variant, the collar R) may consist of elementary collars (2) the edges of which may overlap (interlocking in scales).

 - The junction of the sleeve (3) and the flange (2) may consist of a zone of reduced thickness (19) allowing the flap or the fold of the flange (2) reducing the size of the system for its packaging ( figure 13). This system is particularly recommended for flanges (2) made up of elementary flanges.

 Any internal flange (Figure 14) on the sleeve (3) or cap (1) and any bulge and crushing of the sleeve or cap (20) intended to protect the fingers of the manipulator from the tip of the needle (5) is assimilable. to the collar described above.

Disc-flange secured to the cap
All the flange systems (2) described above can be integral with the cap (Figure 15).

 The cap is in a sterile atmosphere. This can be ensured - either by a strip of paper.

- either by self-breaking welding of the cap (s) (t) with overcap (13)
(figure 9).

 - either by sterile overpack.

- Either by plugging the needle capsule (Figure 16) by an overcap (13).

According to variant of FIGS. 7 and 8, the guide (12) can slide or move by different systems along the body of the syringe (6) while remaining integral with the latter: - either with part of the cap (1) swivel to release the latter from
The needle (5).

- either by guide bar (12) bent at its end (15) to replace the
cap (1), allowing the end of the needle (5) to be covered (figure 17).

This bent part (15) may have a slot or an opening in which
slide the needle (5).

Systems for stopping or blocking the strip (12) can be envisaged
at the start or end of the race.
