The application relates to a needle protection assembly () comprising: &#x2014;a supporting element () and a needle shield (), &#x2014;one locking element () located within said needle protection assembly () and not accessible to the user, &#x2014;urging means () for displacing said needle shield (), &#x2014;a peg () located on said supporting element () or on said needle shield (), and a cam () located on said needle shield () or on said supporting element (), and &#x2014;said locking element () is not formed by said peg () and cam (). The respective longitudinal axis of the needle shield () and of the locking element () are merged when said needle shield () is in its before use or in use positions, and they form an angle (a) when said needle shield () is in its after use position.

Needle protection assembly

The application relates to a needle protection assembly () comprising: &#x2014;a supporting element () and a needle shield (), &#x2014;one locking element () located within said needle protection assembly () and not accessible to the user, &#x2014;urging means () for displacing said needle shield (), &#x2014;a peg () located on said supporting element () or on said needle shield (), and a cam () located on said needle shield () or on said supporting element (), and&#x2014;said locking element () is not formed by said peg () and cam (). The respective longitudinal axis of the needle shield () and of the locking element () are merged when said needle shield () is in its before use or in use positions, and they form an angle (a) when said needle shield () is in its after use position.

The present invention relates to an injection device () comprising: &#x2014;a body () designed to receive a product to be injected, furnished at its distal end with an injection needle () and receiving a piston () capable of being moved between a storage position and an end-of-injection position under the effect of a distal pressure exerted on a piston rod () to the distal end of which it is attached, &#x2014;means of protecting the injection needle () capable of adopting an initial position, during which the injection needle () is uncovered, and a final position, in which the said injection needle () is covered, &#x2014;biasing means () aiming at moving the said covering element () from its initial position to its final position, &#x2014;immobilization means () aiming at keeping the said covering element () in its initial position, the said injection device () being characterized in that: &#x2014;the said piston rod () comprises at least a first portion () and at least one second portion () coupled to the said piston (), the said first and second portions () being operatively coupled together and selectively movable together in the distal direction, at least one of said first portion () and said second portion () being movable in the proximal direction separate from said other one of said first portion () and said second portion ().

Injection device preventing the return of the piston when the safety system is deployed

The application relates to needle protection assembly ()) comprising:&#x2014;a support () of the needle (),&#x2014;a needle shield () having a longitudinal axis A,&#x2014;urging means () for displacing said needle shield () from a 'in, use' position to a 'after use' position,&#x2014;a locking element () intended to prevent said needle shield () from moving back from its &#x201c;after use&#x201d; position to its &#x201c;in use&#x201d; position, characterized in that said locking element () has a longitudinal axis B and is radially movable with respect to said needle shield () between a &#x201c;free&#x201d; position, in which the longitudinal axis A of the needle shield () and the longitudinal axis B of the locking element () are merged and in which said needle shield () is movable from its &#x201c;in use&#x201d; position to its &#x201c;after use&#x201d; position, and a &#x201c;locking position&#x201d;, in which the longitudinal axis B is radially spaced apart from the longitudinal axis A and in which movement of the needle shield () from its &#x201c;after use&#x201d; position to its &#x201c;in use&#x201d; position is prevented.

A cartridge for assay of a target nucleic acid sequence in a liquid sample. The cartridge comprises: a fluidic portion through which the sample flows and in which nucleic acid amplification and detection takes place; a pneumatic portion which controls flow through the fluidic portion; and at least two electrodes which provide a potential difference for the detection of an amplified nucleic acid of interest.

Fluidic cartridge for nucleic acid amplification and detection

A vessel of a malleable or moldable material having one or more side walls and a closed base integral with said one or more side walls, an opening in the top of the vessel, and further comprising two or more projections extending into the interior of the vessel generally laterally from said side walls, wherein said projections are also integral with said side wall. Vessels of this type are produced by a process in which ridges are deformed into projections within a vessel blank, and this process forms a further aspect of the invention. They are particularly useful for holding solid masses such as small beads or cakes in position in the vessel.

Vessel and process for production thereof

The present invention relates to a needle assembly () to be used in combination with a storing device () comprising a barrel () defining a chamber () receiving a product () and a piston (), the assembly () comprising: &#x2014;needle-bearing portion () in a first material, movable between an exposed and a retracted positions of the needle (), &#x2014;engaging means (,) for securing said needle-bearing portion () to said barrel () in the exposed position, characterized in that it comprises: &#x2014;sealing means () in a second material for tightly sealing the distal end () of said chamber () to said needle-bearing portion (), &#x2014;a breakable portion () located between said engaging means (,) and said needle-bearing portion (), which, when broken, allows independent proximal displacement of said needle-bearing portion () relative to said engaging means (,) between said exposed and said retracted positions, said first material being more rigid than said second material. The invention also relates to an injection device () comprising said needle assembly () and a storing device ().

Injection device with retractable needle

The application relates to a needle protection assembly () comprising:&#x2014;a supporting element () and a needle shield (),&#x2014;one locking element () located within said needle protection assembly () and not accessible to the user,&#x2014;urging means () for displacing said needle shield (),&#x2014;a peg () located on said supporting element () or on said needle shield (), and a cam () located on said needle shield () or on said supporting element (), and&#x2014;said locking element () is not formed by said peg () and cam (). The respective longitudinal axis of the needle shield () and of the locking element () are merged when said needle shield () is in its before use or in use positions, and they form an angle (a) when said needle shield () is in its after use position.

The present invention relates to an injection device () comprising:&#x2014;a body () designed to receive a product to be injected, furnished at its distal end with an injection needle () and receiving a piston () capable of being moved between a storage position and an end-of-injection position under the effect of a distal pressure exerted on a piston rod () to the distal end of which it is attached,&#x2014;means of protecting the injection needle () capable of adopting an initial position, during which the injection needle () is uncovered, and a final position, in which the said injection needle () is covered,&#x2014;biasing means () aiming at moving the said covering element () from its initial position to its final position,&#x2014;immobilization means () aiming at keeping the said covering element () in its initial position, the said injection device () being characterized in that:&#x2014;the said piston rod () comprises at least a first portion () and at least one second portion () coupled to the said piston (), the said first and second portions () being operatively coupled together and selectively movable together in the distal direction, at least one of said first portion () and said second portion () being movable in the proximal direction separate from said other one of said first portion () and said second portion ().
