- the housing 8 of the disposable part 6 is equipped with a hook 88 which constitutes a member for securing the parts 4 and 6 in the assembled configuration of the product administration device 2.
- the hook 88 is integral with the half-shell 84 and comprises a head 882 and a rod 884 which connects the head 882 to the rest of the half-shell 84.
- the half-shell 124 also includes a rigid portion 136 which defines a ramp 138 for sliding the head 882 during a movement of parts 4 and 6, in the direction of the arrow F1 in Figure 2.
- the rigid portion 136 also defines a hooking surface 140, perpendicular to the axis X16, against which the head 882 abuts in the assembled configuration of parts 4 and 6 of the product administration device 2, as shown in Figure 5.
- a push button 52 is mounted on the housing 12 and comprises a head 522, of preferably convex external shape, which is received in a housing 142 of corresponding shape, this housing being defined by the two half-shells 122 and 124. Without action of a user on the push button 52, the exterior surface 522S of the head 522, that is to say the surface of this head which is visible from the exterior of the housing 12, is flush with an exterior surface 12S of the housing 12.
- the push button 52 also includes a rod 524 which extends along the longitudinal axis A52 and which is made up of several bars including two bars 526 each equipped with a harpoon point 528 and a bar 530 which defines an end 525 of the rod 524 opposite head 522.
- the harpoon points 528 serve to retain the push button 52 on the housing 12 in the mounted configuration of the reusable control assembly 4.
- the axis A52 is superimposed on an axis X12 defined by the housing 12 and which is a sliding axis of the push button 52 in the housing 12.
- the push button 52 is pushed back by two springs 54 into the position of Figures 1, 2 and 5, where its rod 524 does not interact with the hook 88 and where the surfaces 522S and 12S are flush.
- the external surface 522S of the head 522 bears a mark 532 which represents a padlock, in order to remind that the push button 52 makes it possible to unlock the disposable part 6 with respect to the reusable control assembly 4.
- a mark 532 which represents a padlock
- the push button 52 exerts, by means of the end 525 of the rod 524, a force E2 directed, and sufficient intensity, to push the head 882 of the hook 88, so as to release it from the hooking surface 140.
- the movement of the head 882 of the hook 88 under the action of the push button 52 takes place by means of an elastic deformation in flexion of the rod 884 of the hook 82.
- the push button 52 is movable in translation, along the axes A52 and X12 combined, between a first position shown in Figure 5 and a second position shown in Figure 6.
- the first position is different from the second position.
- push button 52 In its first position in Figure 5 and when parts 4 and 6 are assembled, push button 52 is not in contact with hook 88, so that it is clear of this hook. In other words, in this position, the push button does not interact with the hook 88.
- the push button defines, with the hooking surface 140, a zone Z1 for receiving the hook 88. In its second position, the push button is located in the hook reception zone Z1.
- the push button 52 makes it possible to authorize a separation of parts 4 and 6 of the product administration device 2, from the assembled configuration shown in Figures 1 and 5.
- the joining of parts 4 and 6 of the product administration device 2, obtained by the hook 88, is thus reversible.
- Such separation should not take place under any conditions.
- such separation must not take place when the piston 16 is engaged in the body 102 of the cartridge 10 because, in this configuration, the piston, or even the mechanism 48, could be damaged during, or following, the separation of the parts 4 and 6.
- the piston 16 would then be exposed to the outside of the housing 12 and it would not be possible to mount a new disposable part 6, of which the cartridge 10 would be full, on the control assembly 4.
- only part of the product would have been administered, which is not desirable in the case of therapeutic treatment.
- such separation is to be expected only after the product contained in the cartridge 10 has been consumed in the planned quantity and the mechanism 48 driven by the motor 42 has returned the piston 16 to its rest position.
- the reusable control assembly 4 comprises a blocking member 60 which makes it possible to immobilize the push button 52, in translation along the axes A52 and X12, even if a force E1 is exerted on the external face of the push button 52.
- This blocking member prevents untimely or accidental separation of parts 4 and 6 of the product administration device 2.
- the blocking member 60 blocks the push button 52 in its first position when necessary.
- A60 as a longitudinal axis of the blocking member 60.
- the blocking member is constituted by a shuttle 60.
- the shuttle 60 is a one-piece part which comprises a rod 602 and a flange 604, which constitutes an enlarged portion relative to the rod 602 and which surrounds this rod.
- the collar 604 can be of polygonal section, in particular square.
- 606 one end of the rod 602 facing the piston 16. The end 606 can be described as the front end of the rod 602.
- the shuttle 60 is guided by bearings 144 formed by the half-shell 124 and which define a longitudinal axis Y12 of a housing 137 in which the shuttle 60 is received.
- the housing 137 is defined by the housing 12.
- the axes X12 and Y12 are perpendicular.
- the axes X12 and Y12 are non-parallel, without being perpendicular.
- the axes A60 and Y12 are combined and the shuttle 60 is mobile in translation along these combined axes, being guided, along the axes Y12 and A60, by the rod 602 which cooperates with the bearings 144.
- the shuttle 60 is loaded by an elastic member 62, in a direction parallel to the axes A60 and Y12, towards a configuration where the collar 604 is received in a housing 534 defined by the push button 52.
- the elastic force exerted by the elastic member 62 is directed towards the piston 16.
- the elastic member 62 is formed by a metal helical spring mounted around the rod 602, which guarantees uniform application of the force of elastic return of the shuttle 60 towards its position shown in Figure 5. The risks of jamming of the shuttle 60 are thus minimized.
- spring 62 is received in housing 534.
- the elastic member can be a spring of non-helical shape and/or made of a non-metallic material or even an elastic tongue in one piece with the body 12.
- the flange 604 and the housing 534 are of generally complementary shapes and their geometry is defined such that, when the flange 604 is received in the housing 534, it blocks a translation of the push button 52 in a direction of depression to the interior of the housing 12, from the configuration shown in Figures 1 and 6.
- the housing 534 is provided in the form of a notch passing through a bar 526 which belongs to the rod 524.
- the collar is received in the housing 534 with reduced clearance.
- the collar can be received in the housing with a clearance allowing a short depression of the push button 52 in the housing 12, provided that this does not lead to pushing the head 882 with the end 525 of the rod 524.
- the shuttle 60 When its collar 604 is engaged in the housing 534, the shuttle 60 is in a position where it blocks the push button 52 in its first position, where the end 525 of the rod 524 is released from the hook 88. This means that, in its locked position, the shuttle prevents parts 4 and 6 from being separated from the product administration device 2.
- the spring 62 returns the shuttle 60 by default to its locked position.
- the rear face 165 in particular its flat annular portion, thus constitutes a suitable abutment surface to come to bear against the shuttle 60 in a configuration where the thrust element 163 maintains the shuttle in a button unlocking position.
- pusher 52 where it is held by the piston 16, as long as the latter remains in its rest position.
- the shuttle 60 does not oppose a pressing movement of the push button 52 in the housing 12, under the effect of the force E1.
- the push button is pressed into the body 12, to the point that the end 525 of the rod 524 comes, thanks to the force E2, to push the hook 88, which is then released from the hooking surface 140. This frees the disposable part 6 relative to the reusable control assembly 4.
- the piston 16 is configured to control the movement of the shuttle 60 along the axes A60 and Y12 combined. Indeed, if the piston 16 is disengaged from the rod 602, it lets the spring 62 push the shuttle 60 towards the configuration shown in Figure 5 and the blocking member, that is to say the shuttle, is in the push button locking position. On the contrary, if the piston 60 presses on the end 606 of the rod 602, it pushes the shuttle 60 out of the housing 534, as shown in Figure 6 and the blocking member, that is to say the shuttle , is in the unlocking position, compatible with the movement of the push button 52 against the force exerted by the springs 54.
- the position of the shuttle 60 in the configuration of Figure 5 is a blocking position, where the shuttle 60 blocks the push button 52 in its first position.
- the position of the shuttle 60 in the configuration of Figure 6 is an unlocking position, where this shuttle authorizes the passage of the push button 52 from its first position, released relative to the hook 88, towards its second position, where it pushes the head 882 relative to the rigid portion 136.
- the piston of this second embodiment also comprises a rod 161 and a thrust element 163.
- the thrust element 163 comprises two parts 163A and 163B assembled together.
- the second embodiment differs from the first embodiment in that, on its rear side 16B, the thrust element 163 is provided with a flange 168 of which we note 165 the rear edge, opposite the nose 162, and 172 the external peripheral surface.
- Surface 172 is frustoconical and converges towards the rear of piston 16, with a half-angle at the vertex a, this angle being formed between surface 172 and axis X16 along which piston 16 moves.
- the rigid portion 136 of the housing 12 defines an internal surface 145 which is frustoconical, centered on the axis X10 and of which we note p the half-angle at the top.
- angles a and p are advantageously equal.
- surfaces 145 and 172 are inclined at the same angle relative to axis X16.
- the surfaces 145 and 172 constitute guide surfaces which cooperate to guide the thrust element 163, therefore the piston 16, when it is moved from or to its rest position, comparable to that shown in Figure 6 for the first embodiment.
- the edge 165 of the collar 168 comes to rest against the end 606 of the rod 602, which pushes the collar 604 out of the housing 534, according to an operation comparable to that explained above for the first embodiment.
- the rear edge 165 also constitutes a suitable abutment surface to come to bear against the shuttle 60 in a configuration where the thrust element 163 maintains the shuttle 60 in an unlocked position as long as the piston 16 is in its rest position.
- angles a and p are advantageously between 20° and 70°, preferably between 30° and 60°.
- the surfaces 145 and 172 can be inclined relative to the axes X10 and X16 without being frustoconical.
- the piston 16 when the piston 16 is in its rest position, it pushes the collar 604 out of the housing 534, and therefore the shuttle 60 towards a position for unlocking the push button, where the force E1 exerted on the head 522 of the push button 52 makes it possible to operate the hook 88. Conversely, as soon as the piston 16 reaches one of its operating positions, the force exerted by the spring 62 pushes the shuttle 60 from its position unlocking towards a blocking position of the push button, where the collar 604 is engaged in the housing 534.
- the locking member 60 may be different from a shuttle. It may have a shape other than that shown in the figures and not be in one piece.
