It consists of a depositing apparatus comprising a support 1 whose base is provided with a centre 11 comprising a conical outer surface 24, and a collection receptacle 12 comprising an upper part provided with a central opening bordered by small hinged plates 17, forming a diaphragm when fitting the depositing part. An annular groove 25 made in the base 1 close to the conical part 24 of the centre 11. The upper part of the receptacle comprises a raised rim 18 around the periphery of the diaphragm 17, intended to form an anchorage for holding the depositing apparatus, as well as for holding a lid intended to cover the diaphragm 17. The collection receptacle 12 is provided with a vertical T-shaped tab 16 which interacts with a U-shaped slideway 19 for a support member which furthermore comprises at the rear small magnetised plates 20 and is extended by a tab 21 ending in a stop 22. This assembly is particularly intended for the medical and paramedical environment for collecting and destroying contaminated needles, ensuring the prevention of diseases with high infection risks.

Description

 The present application relates to a certificate of addition to the nitial application of patent No. 8617794 filed on 19/12/1986 having as an object a device for depositing hollow needles for injections, samples and transusions, their support allowing the evacuation of these without mauel contact in a recovery container.

According to this main patent, the device is composed in its upper part,
'' a base fixed on the collection container for soiled needles, by threading or clipping using a centralizer; this base supports two jaws and their deflectors which act as a lever and form a protective screen for the manipulator. With the device unlocked, the operator engages the needle in
'orifice, exerts pressure on the plunger, the needle is pinched ar the streaks of the jaws. A movement of rotation on a vertical from bottom to aut exerted on the needle support allows to release it, the operator then releases the plunger, the opening of the device is done automatically at
With the help of the return spring and the needle drains itself into the container.

 After evacuating the needle, the operator locks the device in the closed position using a locking device which ensures that the recovery container is closed.

 The object of the present request for addition with the aim of bringing improvements to the structure of said assembly in order to improve security and storage and to obtain a better seal in connection level between upper part and container and means for stabilizing and holding the container itself.

 Indeed, the recovery container is intended to be handled several times: firstly to be assembled with the removal device, then once filled, to be separated from this same device and then to be incinerated. .

According to a first characteristic of this additive, the upper element of the apparatus is provided in its lower part with an opening bordered by a conical nettle ending in the upper part by a groove made in
The base forming a centering device.

The container comprises directly or indirectly as a cooperative part of said base a flat annular part internally bordered by the
Articulated shovels that fold down to form a diaphragm, the so-called lamel
The are lowered by the centering element when the upper device is put in place and are brought back by elasticity to their flat position when the said device is removed.

 Said upper part cooperating with the base of the lower element is constituted according to one embodiment of a cover attached to the recovery container.

 According to another characteristic, the stability of the container is obtained by its frustoconical shape, the circle of which is supported on a stop of a magnetic support linked by slide to the container.

 By way of illustration of a nonlimiting embodiment of the invention, the drawings are attached.

 Figure 1 shows in section the removal device placed on the recovery container, all placed on the magnetic device.

 Figures 2 and 3 show a top view and side view of the recovery container.

 Figures 4 and 5 show a top view and side view of the container lid.

 Figure 6 shows the lid of the container lid.

 Figures 7, 8, 9 show the magnetic support.

 With reference to these drawings, the device consists in its upper part of a base or base (1) supporting a fixed jaw (2) and a movable jaw (3) defining between them an orifice (4) where one introduces the needle (5), the two jaws are striated (6) in order to eliminate the rotation of the needle (5) during removal, deflectors (7) arranged laterally to the jaws provide perfect protection for the operator opposite the needle during handling, their extension also serves as a lever, provided with a pusher (8), said deflectors being integral with the movable jaw (3) and articulated by an axis (9) fixed on the base (1) which is hollowed out in the axial central part of the device (10) to allow the needle (5) to be discharged towards the container (12). The base (1) is fixed by clipping or screwing, to using a centering device (11) provided with a conical exterior (24) on said recovery container (12).

 In the variant illustrated in fig 1, a clip system (13) ensures the locking of the movable jaw on the base, a spring (14) placed under the pusher allows the automatic opening of the device when it is unlocked.

 The device according to the invention is made of plastic which makes it therefore sterilizable.

In its lower part, the device is provided with a conical collecting container (12), externally having on its rear face a vertical T-shaped support tab (16) which is introduced into a slide (19) U-shaped with two opposite fins, of a magnetic support illustrated
;. 7 and 9 thus positioned the recovery container becomes stable during
manipulations. Due to its conical shape, it ensures sufficient capacity
putting the disposal of used needles during the patient's stay as well
ease of storage and space saving.

A circular cover illustrated in fig. 4 comes to refer to the container
3. 2 by clipping or screwing, it has a diaphra on its upper face
centered (17) opening downwards through the seat of the depositing device
g. 1 provided with a groove (25), a raised edge (18) bypassing at the periphery
e the diaphragm having a double function; anchor and stabilize
tee of the removal device (1) cooperating with the groove (25) as well as
retaining element for closing the recovery container after re
of the depositing apparatus, by a cover (23) making the container watertight
the, inviolable and secure Until incineration.

According to other particular characteristics, the magnetic support is
provided at the rear with vertical magnetic strips (20) allowing its
fastening on a metal plane arranged behind the glis part
ière (19), U-shaped with two opposite fins, intended to receive the tab
e support (16) of the recovery container (12) said support is extended
n its lower part of a vertical tab (21) ending in a part with a front and rear projection forming a stop (22) with a double function: a) ensuring balance against the fixing surface, b) promoting the stability of the container (12) and the vertical position of said assembly in the working position by pressing its lower face on the front projection of the stop (22).

 The recovery container, its cover and its lid can be made of plastic material which is destroyed by incineration and the grounded support is made of rigid plastic material.
