Method, system and device involving a needle device with a needle safety element with improved stable structure. A frame can surround the needle safety element to provide added stiffening of the needle safety element. The frame can include stays extending laterally of the needle safety element. The needle safety element with the frame can be slidably located on a needle and in a catheter hub in a ready to use position and be removable from the catheter hub in a protective position.

In one aspect, a medical injector is provided herein having a body and an overcap releasably attached to the body configured to prevent mounting of a needle prior to mixing of components within the body. In a further aspect, a slidable collet may be provided useable to urge resilient members from an outward disrupted state inwardly to collectively define a needle mount. Advantageously, a medical injector is provided which ensures proper sequence in preparation of the device, particularly with respect to the step of allowing mounting of a medical needle to the device subsequent to preparation of the medicament to be administered.

The present disclosure describes anti-needle stick safety mechanism that is passively activated during the normal course of giving an injection. In one embodiment, the device includes a spring member coupled at a proximal end to a needle member and at a distal end to a needle cover. The passive activation of the device is triggered when the needle is inserted to a minimum depth into the patient's tissue to unleash the force of a compressed spring to urge a needle cover towards the distal end of the needle. As the needle is withdrawn from the tissue, the needle cover advances to the end of the needle and as it partially clears the end of the needle, it adopts an orientation that prevents the needle tip from re-emerging from the needle cover.

A method of using a power-injectable port includes obtaining the power-injectable access port, attaching a catheter to an outlet stem of the power-injectable access port, and implanting the power-injectable access port and the catheter into a patient. The method further includes identifying the power-injectable access port following the implanting, inserting a distal end of a needle through the septum and into the reservoir, and injecting contrast media through the needle at a rate of at least one milliliter per second. The power-injectable access port includes a housing, a septum, a reservoir, and an outlet stem in fluid communication with the reservoir. The power-injectable access port is rated for injection of contrast media at a flow rate of at least 1 milliliter per second. The power-injectable access port is structured for operation at a pressure in the reservoir of at least 35 psi.

A shield for a needle of a peripheral intravenous catheter or other IV catheter system is provided. The shield may be formed of a single piece of material that may be bent to form a top portion, a bottom portion, a proximal portion, a top distal portion and a bottom distal portion. The proximal portion may form a proximal needle opening and the top or bottom distal portion may form a distal needle opening to allow a needle to extend through the shield when the shield is positioned within the lumen of a catheter adapter. When the distal tip of the needle is withdrawn proximally, the shield may transition from an unlocked position to a locked position in which the distal tip will be retained within the shield.

A device for protecting a user from a sharp tip of a medical needle includes a central body portion, a medical needle having a sharp tip, a pair of wings in attachment to the central body portion, and a hook-and-loop fastening system disposed on at least one of the wings, and configured to selectively attach the wings together with the medical needle positioned between the wings so as to protect a user from the sharp tip of the medical needle. A method of using the device includes withdrawing a sharp tip of a medical needle from a patient, closing a pair of wings with the medical needle positioned between the wings, and fastening the wings together with the medical needle positioned between the wings so as to protect a user from the sharp tip of the medical needle.

Needle assemblies are generally discussed herein with particular discussions extended to needle assemblies having a tip protector with a plurality of wall surfaces for preventing contact with the needle tip from a side. Aspects of the tip protectors discussed herein include a first protector body having an arm for blocking a needle tip surrounded by a second protector body having a plurality of wall surfaces.

The present disclosure is directed to a catheter insertion device, which has a catheter hub at the proximal end of a catheter, a tubular needle hub, at which a hollow needle is fixed and extends through the catheter hub and the catheter in a ready position such that the needle tip projects over the distal end of the catheter, a protective barrel which is received in the tubular needle hub in the ready position and is releasably connected to the catheter hub, and a pressure spring arranged between the needle hub and the protective barrel and which displaces the needle hub and the protective barrel apart from each other in an axial direction, wherein a manually operable holding member is provided between the needle hub and the protective barrel, and holds the needle hub in the ready position at the protective barrel against the bias of the pressure spring, so that after the holding member is released, the pressure spring moves the needle hub into a protective position in relation to the protective barrel, in which position the needle is positioned in the protective barrel.

A safety needle assembly includes a housing and a cannula hub connected within a side wall of the housing, a needle connected to the cannula and extending from the cannula hub outward from a proximal end of the housing, and a spring connected with the housing. The assembly includes a barrel connected with the spring and at least partially contained within the housing to least partially cover the cannula hub. The barrel is configured for moving, sliding, traveling, activating, relocating, or transitioning from a first mode in which the barrel is securely retracted and locked at least partially within the housing and the needle extends through an aperture of the barrel and the proximal end of the housing, to a second mode in which the barrel extends from the proximal end and beyond the needle.
