The present invention relates to a housing-receiver for cannulas injection syringes"

In hospitals, is used

increasingly syringes composed of a syringe and an injection cannula fitted "A means for surely receive the injection cannula after their use, to allow transported to the heap of refuse without-risk of injury or infection"

-To this end, the invention relates to a housing for holding the cannula, whose rear end is reinforced and from injection syringes "The housing is characterized in that it consists of a sealed container having at least one wall provided with holes, each hole for the introduction into the housing of a cannula attached to a syringe, the edges of the holes forming, because of their structure, a support for the rear end reinforced of the cannula, avoiding the extraction of the cannula out of the housing."

According to another feature of the invention, the holes will decreasing toward the inside of the housing and the inner edge of the holes is sharp "These holes have a square cross-section"

After using the injection syringe, cannula is plugged that it carries, in one of the holes of the housing, until the end of the cannula reinforced rear passes under the perforated wall. One then removes the cannula from the syringe, for disposal " The cannula which is dangerous is thus row in the housing. With the quadrilateral shape of the holes, it is also possible to use cannulas and the back ends of which are of different shapes. In effect, this square shape allows a larger strain heads would cannula than the round holes "At the same time, these holes square form supports at the corner for heads of cannula particularly dimension Guests"

The present invention will be described in more detail by way of non-limiting example

using the accompanying drawings, in which:

-Figure 1 is a perspective view d^, a housing according to the invention;

-Figures 2,3 and 4 are sectional views showing the attachment of cannulas;

Figure 5-is a longitudinal section of the housing of Figure 1;

Figure 6-is a cross-section of an alternative embodiment housing"

The housing 10 consists of an upper part 12 and a lower portion 14 "These two parts 12,14 are provided with outer flanges by which the two parts abut one another by being joined integrally by rivets 16" The upper portion 12 has a wall pierced 18 grid constituting a large number of holes 20 square tapering from top to bottom, i.e. to the inside of the housing " The two parts 12, 14 are plastic"

Inside the housing 10, there is provided a protective wall 22 directly below the perforated wall 18 "The wall 22 is made of a material which can be penetrated easily for example a synthetic foam" This protective wall 22 is integral with support walls 24 side are supported on the portion, of the lower housing 14 "In the protective wall 22, it is provided a lining 26 in the housing 10" The liner is impregnated with a disinfectant and it is sealingly enclosed by a sheath 28 "Since lining, is used an absorbent sponge that is vacuum-packed in a sheet welded"

When tip 30 furnished with the cannulated 32 in a hole 20 in the direction of arrow of Figure 2, is passes first through the plastic foam panel 22, the sheath 24 , so that the vacuum prevailing in the lining 26 draws somewhat residual liquid remaining in the liner "By continuing the depression of the cannula 32, the rear end 34 reinforced elastically deforms as a result of the shape of the edge of the hole 20, until the end 34 passes under the perforated wall 18 (Figure 3)" In this position, the cannula is hooked securely with respect to the housing and the small syringe 30 be removed by pulling in the direction of the arrow according to Figure 4, the cannula remaining attached in the housing.

The support walls 24 of the protective wall 22. prevent * upon depression of the cannula into the wall 22, is applied a back pressure on the packing 26, ' because this counter-pressure could create an overpressure ejecting accidentally residual liquid remaining in the cannula * upwardly o The square shape of each port 20 allows for a plethora of cannula 34 heads of different shapes and dimensions, which would be the case for round holes. Indeed, .can be deformed larger cannula the heads and, in the case a cannula head extremely small, the corners of the holes is used as supports.

II is important that the edge, lower, i.e. on the inner surface of the orifice wall 18 of each port, or in the form of random access strip to form a secure attachment, in particular in the case a cannula head particularly small"

Figure 6 represents a cylindrical housing 40 whose entire cylindrical wall is in the form of a perforated wall. The cylinder 40 is rotatably mounted in a mounting housing 42 surrounding the hole cylinder 40 on the larger part in leaving that an axial slot 44 through which access is gained to a row of holes for driving cannulas. When a row of holes is lined with cannulas, is rotated, the cylinder slightly to place the next row of holes opposite the slot.

Inside the housing hole 40, it is also provided a protective wall of cylindrical shape, the material that can be pierced.

* In this protective wall is provided a liner corresponding to the liner 26 of the previous example.

In below the hole cylinder 40, to the Interior the mounting housing 42 * is a receive buffer k & absorbing liquid drops which may escape.

The various embodiments described above have in common a maneuver to allow one hand in order to hook safe. Cannulas in a device/receiver, which, when packed cannula, can be transported and sansrisque to * same pitch is a harmful element to traumatize or infecting même' on the waste heap"

Of course, the invention is not limited to the examples above described and represented, from ' which can be providing other forms and other embodiments, without dislodging from the frame of the invention"
