The present disclosure relates to a medicament delivery device comprising: a housing configured to receive a cartridge containing a medicament; an injection needle having a proximal end and a distal end; an injection needle holder to which the injection needle is fixed, the injection needle holder being moveable relative to the housing between a rest position and a use position; and an injection needle cap detachably connected to the injection needle holder and enclosing the proximal end of the injection needle. The medicament delivery device is configured such that pushing the injection needle cap towards the cartridge causes the injection needle holder to move from the rest position in which the distal end of the injection needle is spaced from the cartridge towards the use position in which the distal end of the injection needle can engage the cartridge.

A method for treating a tip cover for an injection device to reduce the pull out force of the tip cover. The method includes applying a quantity of a first silicone oil and a quantity of a second silicone oil to an inner surface of a tip cover, the inner surface configured to engage an outer surface of a tip of an injection device and treating the silicone oils to form a cross-linked silicone coating on the inner surface of the tip cover.

Drug delivery devices are described that provide hybrid forms with gripping and stability functionalities, such as a grip portion on a skin contact surface. In some versions, the drug delivery devices can include a cep having a release liner such that removal of the cap exposes the grip portion. In some versions, the drug delivery devices include a retractable needle guard having the grip portion extending therearound.

The invention relates to a safety device for a syringe for avoiding stab wounds, said syringe having a syringe body and a piercing means arranged on the distal end of the syringe body. The safety device comprises a sleeve element that extends along an axial direction (X) and encloses at least partly the piercing means and the syringe body, and a collar element that can be arranged on a distal end region of the syringe body and locks the safety device in the axial direction (X), said collar element having at least one guide projection which engages at least one guide track of the sleeve element. The safety device is further characterized by having a cap element that can be arranged at least in sections on top of the sleeve element and by means of which the sleeve element can be locked with respect to the movement of the syringe body relative to the sleeve element.

Disclosed is a method for assembling a safety device and mounting the safety device on a syringe member before the syringe member is filled, said method comprising the steps of: providing a sleeve, a spring element and a mounting element; introducing the spring element into the sleeve along a mounting direction; introducing the mounting element into the sleeve along the mounting direction; obtaining the safety device; before the syringe body is filled, mounting the safety device on the syringe body by connecting the mounting element to the syringe body.

Disclosed are applicators and methods injecting of a liquid anesthetic into a dental patient with no or minimal pain. In accordance with one embodiment the applicator is for intraligamentary injection and includes an elongated, thin member having an open distal free formed of a resilient and somewhat conformable material suitable for producing a substantially fluid-tight interface with the anatomic structures at the gingival sulcus to inject the anesthetic therein. In another embodiment the applicator includes a flexible skirt surrounding a sharpened cannula, with the cannula being movable with respect to the skirt. The skirt is arranged to receive the anesthetic to anesthetize the gum, whereupon the cannula can then pierce the gum to inject the anesthetic into the underlying anatomic structure.

A syringe assembly includes a barrel having a barrel tip portion, a puncture needle projecting from the barrel tip portion, and a cap that is detachably mountable to the barrel so as to seal a distal end of a needle hole. The cap has a receiving hole that receives the puncture needle, a bottom wall portion into which the puncture needle is inserted, and a stopper portion that defines an insertion length of the puncture needle relative to the bottom wall portion. In a state in which the cap is mounted to the barrel, the length from the most proximal position of a contact region between the cap and the puncture needle to the most proximal position of an edge surface is 1 to 3 mm.

Disclosed are applicators and methods for injecting a liquid, such as anesthetic, into a patient with no or minimal pain. The applicator includes a coupling and a blade rotatably mounted on the coupling. The coupling is arranged to receive a cartridge in which a cannula is mounted such that the cannula extends through a proximal channel of the coupling and into a distal channel of the blade. The coupling is further arranged to secure the applicator to a source of liquid such that the liquid can be selectively introduced into and through the cannula into the tissue of the patient. The blade is thin enough for atraumatic insertion into a gingival sulcus of the patient.

The injection assembly (2) includes a prefilled injection device (3), such as a syringe, provided with a coupling tip (16), for example of the Luer-Lock type, and a protection device (4) comprising a protective portion (23) removably mounted on the coupling tip (16), a supporting portion (30) connected to the protective portion (23), and an injecting element (34) removably mounted on the supporting portion (30) in a storage position. The injecting element (34) comprising an injection needle (35) and a connecting tip (36) fluidly connected to the injection needle (35), the connecting tip (36) being adapted to be mounted on the coupling tip (16) of the injection device (3) in a position of use of the injecting element (34). The injecting element (34) and the supporting portion (30) are arranged in such a way that, in the position of storage of the injecting element (34), the connecting tip (36) is accessible to cooperate with the coupling tip (16).
