A needle shield remover for removing a needle shield covering a needle on a syringe includes a body having a proximal portion and a distal portion. The distal portion is moveable between a contracted configuration and an expanded configuration in response to opposite movement of the proximal portion. The distal portion includes an internal opening for receiving and at least partially surrounding a needle shield therein. An anchor extends inwardly from the distal portion into engagement with the needle shield when the distal portion is in the contracted configuration to secure the body to the needle shield. A sleeve is in fixed axial arrangement with the proximal portion of the body. The axial engagement maintains the distal portion of the body in the contracted configuration such that force applied to the sleeve away from the body removes the needle shield and body from a syringe.

The present invention provides a deflectable guide whose use results in protection of the hand of medical personnel holding a medical container during the activity of moving a hypodermic needle toward and pressing it through a septum of the medical container. The present invention further is adapted for use of the same syringe and deflector guide protected needle for injection or withdrawal of medical liquids from a septum end of medical catheter or intravenous tubing without removal of the deflectable guide.

Embodiments of a retractable syringe assembly are provided that include a dual syringe barrel configuration. One or more embodiments include reuse prevention features and features that prevent premature activation of the retraction mechanism. Methods for aspirating and expelling liquid from medical devices are also provided.

A cap remover for removing a cap covering a needle of a medical injector includes a body having an insertion portion at its proximal end configured to at least partially accommodate the cap, and a grabbing portion at its distal end having an internal cavity which includes an extraction member having a series of laminas extending radially and inwardly from a ring.

A rigid needle guard (10) comprising an inner part (11) made of elastomeric material, and a rigid outer body (12) that is fastened to said inner part (11) made of elastomeric material via a folded-in portion (121) of the bottom axial end of said rigid outer body (12), said folded-in portion (121) extending radially inwards from the outer peripheral surface (125) of said rigid outer body (12), the outer surface of said folded-in portion (121) forming, at its axially-bottom and radially-outer edge, a sharp and acute angle relative to the outer peripheral surface (125) of said rigid outer body (12).

Provided is a needle removal operation cover with which a user can safely perform an injection needle removal operation even when a needle tip is directly inserted into the needle removal operation cover, and with which the user can remove the injection needle without requiring a wrist twisting motion. In a needle removal operation cover which is configured such that an injection needle which is detachably and threadedly mounted on a distal end of an injection cylinder is threadedly removed by rotating the injection needle, the needle removal operation cover is formed in a cylindrical shape such that a needle tube of the injection needle including a needle tip is accommodated in the needle removal operation cover and integral mounting of a needle hub in the needle removal operation cover is allowed, a flange body for a rotating operation is formed on a cylindrical outer peripheral surface in a projecting manner, an outer periphery of the flange body is formed of a plurality of continuous mountain-like ridge portions, and among the mountain-like ridge portions, the mountain-like ridge portions which correspond to a rotational direction along which the injection needle is released from the injection cylinder are formed into a shape which allows easy engagement of a finger for an operation with the ridge portions.

A needle assembly includes a needle hole having an inside diameter that is greater than an outside diameter of a needle, and by a moving-side guide integrally provided to a needle tip cover being engaged with a fixed-side guide fixedly provided to the needle, a guide mechanism is provided to guide the needle tip cover from a proximal end side towards a distal end side of the needle while maintaining a state of noncontact with the needle, and to guide the needle tip cover to a position where the needle tip cover covers the needle tip while deviating the needle tip cover in a direction in which the needle hole goes away from a center axis of the needle at a position beyond the needle tip, and avoiding contact of the needle tip with the needle hole.

According to the invention, a safety device for a pre-filled syringe with an injection needle comprises of a support body adapted to mount the pre-filled syringe, a needle shield slidably arranged with respect to the support body, a retention and locking means (M) for retaining and locking the needle shield with respect to the support body in a first and a second advanced position (PA1, PA2) and in a retracted position (PR). The needle shield comprises an annular flange adapted to rest on the skin of the patient receiving an injection. The retention and locking means (M) are arranged at a distal end of the safety device.

Needle assembly having the following modes of operation; a first mode wherein the safety shield can move to a first retracted position allowing injection of the piercing portion of needle from a position at least partially covering the piercing portion of the needle and a second mode wherein the safety shield moves to a position protecting the piercing portion of the needle after the first mode and is prevented from moving back to a position exposing the piercing portion of the needle.

A device for delivering a fluid into a biological tissue includes hollow microneedles (10) projecting from a surface (12) of a substrate (14), and a guide element (18) spaced from the substrate. The guide element provides a tissue-contact surface (20) that defines a tissue contact plane oblique to the surface (12) of the substrate (14).
