An injection system includes a body member having a body connection member at a distal end thereof. The system also includes a needle hub assembly coupled to the distal end of the injection system body. The needle hub assembly includes a needle hub coupled to the body connection member, a needle coupled to the needle hub, and a spacer removably coupled to the needle hub. The spacer reduces an exposed length of the needle.

A needle tip assembly for a pre-loaded syringe or a pen needle injection device, the needle tip assembly including a body comprising a double-ended needle and being installable and removable from the pre-loaded syringe or pen needle injection device. A needle cap is configured to cover a skin puncturing end of the double-ended needle and is removable to exposed the skin puncturing end. An outer safety member has a first portion that surrounds the body and a second portion that surrounds the skin puncturing end.

An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.

The invention relates to a safety assembly havingan attachment ring attached to the tip of the container anda safety device covering at least the distal end of the needle, the safety device attached to the attachment ring. The attachment ring has an inner ring having an inner face provided with a snap feature, which engages a complementary snap feature on the tip of the container to prevent axial movement of the inner ring with respect to the container. The snap feature moves radially to engage the complementary snap feature on the tip of the container; and an outer ring is fixed on the inner ring, with a sleeve portion surrounding at least a portion of the inner ring to prevent radial movement of the snap feature once the snap feature has engaged the complementary snap feature on the tip of the container.

A syringe holder includes: a barrel body that holds a syringe; a holder opening; deformation promoting portions; and radial movement-restricting portions. The radial movement-restricting portions are provided close to the deformation promoting portions. Being brought into contact with first portions, the radial movement-restricting portions restrict the syringe from moving in a radial direction with respect to the barrel body.

The present invention relates to an assembly (101) comprising: an injection device (1) comprising a container (2) for a product, said container comprising a distal tip (3), an adaptor (5) comprising a ring (6) mounted onto said distal tip (3), characterized in that said assembly (101) further comprises a heat-shrinkable film (9) covering part (2a) of said container (2) and part (5a) of said adaptor (5), said film (9) maintaining said adaptor (5) blocked in rotation and in translation with respect to said container (2) when said film (9) is in its heat-shrunk condition. The invention further relates to a method for manufacturing such an assembly.

A syringe having a bonded needle, comprising a syringe body, a needle protector comprising a flexible cap, an outer sleeve, which can move along a longitudinal axis between an extended position, in which it covers the needle, and a retracted position, in which it does not cover the needle, and a collar, which is mounted with a radial clearance around an end part of the syringe body and which comprises at least one pin engaged in a guide opening of the sleeve. A portion of the flexible cap fills the radial clearance between the end part of the syringe body and the collar when the cap is mounted on the syringe, such that the collar cannot rotate around the end part of the syringe body as long as the cap is mounted on the syringe.

A fluid transfer device may include a body member and a fluid transfer tip, wherein the fluid transfer tip may include a tapered friction fitting for a corresponding hub. The fluid transfer device also may include a disconnecting member having a front portion and a rear portion and engagement features operating between the disconnecting member and the body member. The engagement features engage with one another to inhibit the front portion of the disconnecting member from moving relative to the fluid transfer tip. The fluid transfer device is arranged such that upon application of a force to the rear portion of the disconnecting member, the disconnecting member deforms so that the engagement features are no longer in engagement with one another. This allows the front portion of the disconnecting member to move relative to the fluid transfer tip and subsequently release the hub from the friction fitting.

A needle and syringe system that provides ultra-low dosage waste and automatic needlestick protection. A syringe assembly is provided that contains a barrel and a plunger. A tubular spacer is disposed in the barrel. A needle head assembly is provided that includes a collar and a needle. A safety slide is positioned between the needle and the collar. The safety slide has a sheathing tube that surrounds part of the needle. The safety slide can move relative the needle. In a first position, the sheathing tube does not extend beyond the sharpened end of the needle. In a second position, the sheathing tube extends beyond the sharpened end of the needle. When advanced, the plunger head moves the tubular spacer. The tubular spacer passes over the base of the needle and presses against the safety slide. The safety slide is moved from the first position to the second position.
