摘要： A low-profile universal passive protector for an IV catheter includes a connector having a tubular body and a pair of arms pivotally connected thereto. The tubular body defines an end face and the connector includes a cavity extending from the end face. An elongate sheath is snap engageable to the tubular body. A spring is insertable within the connector cavity to extend between at least one of the pair of arms and the elongate sheath when received within the cavity. A slider is moveably coupled to the sheath. The slider includes a flashback chamber formed therein. A hypodermic needle is connected to the slider and is in fluid communication with the flashback chamber. The slider is moveable along the sheath between a first position and a second position, with the hypodermic needle being drawn into the sheath as the slider moves from the first position toward the second position.

摘要： A passive safety needle shield is provided. The needle shield comprises a base fixed to a proximal end of a needle, and an enclosure housing initially disposed at a distal end of the needle and enclosing the end of the needle. A hinged arm connects the base and the enclosure housing. The enclosure housing is slidable along the needle length, and the hinged arm flexes to permit the enclosure housing to move along the needle as the needle is inserted into a user, thereby hiding the needle end, and providing support to the needle to avoid bends or buckles in the needle. The hinged arm is biases in the initial position so that the enclosure housing returns to the end of the needle as the needle is withdrawn.

摘要： A disposable safety needle assembly and safety enclosure for internally shielding a used or contaminated needle includes a needle assembly having a needle cannula slidably disposed within a safety enclosure. An angular orientation to the needle within the enclosure maintains an insertion angle allowing the safety enclosure to remain substantially flush with a dermal surface during and while the needle is inserted. The safety enclosure also includes an internally disposed flexible safety member. The flexible safety member has face portion transversely situated and having a safety feature disposed to the needle and that slides thereon. Retracting the needle within the safety enclosure to a point wherein the sharp tip of the needle is beyond the needle protection section of the flexible member causes the protection section to travel transversely to the direction of motion of the needle. As a result, the safety feature receives the sharp tip of the needle.

摘要： 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.

摘要： An insertion device and insertion set. The insertion device for inserting at least a portion of at least one piercing member of an insertion set through the skin of a patient includes a device housing, a carrier body and a driver. The carrier body is slidably received within the device housing for movement between an advanced position and a retracted position. The carrier body also includes a receiving structure to support the insertion set in a position with the at least one piercing member oriented for insertion through the skin of the patient at a predetermined or variable angle relative to the skin of the patient upon movement of the carrier body from the retracted position to the advanced position. The driver is operatively coupled between the device housing and the carrier body to urge the carrier body from the retracted position toward the advanced position to place at least a portion of the at least one piercing member of the insertion set thorough the skin of the patient to install the insertion set to the patient. The receiving structure of the carrier body is removable from the insertion set while maintaining the installation of the insertion set to the patient.

摘要： Improvements in a safety hypodermic needle and a method of making the same are disclosed. The improvements relate to a commercial embodiment of a patented safety needle and comprise a tubular member extruded from a flexible elastomeric or rubber-like polymeric material. The tubular member is extruded with two ribs extending from the outer wall of the tubular member and spaced apart 90° circumferentially. The wall of the tubular member is provided with through cuts to form a cutout on one wall portion and an elongated lever on the opposite wall portion in the 90° space between the ribs. The cuts separate the wall of the tubular member into two outwardly flexible arms, each having a single rib thereon adjacent an edge of the arm. One end of the tubular member is stretched over the needle hub of a hypodermic needle and the other end is stretched over a needle cup which houses the sharp needle point. The needle cup is provided with a needle opening through which the needle extends during use. After use the flexible arms automatically return the needle cup into a protective position housing the needle point. Latching mechanisms are provided on the hub and lever for releasably holding the arms in a “cocked” position or for permanently holding the arms in a disabled or “safe” condition to prevent inadvertent needle sticks.

摘要： A safety needle device and method of supplying fluid to a vascular access port is described. The device may include a base member, a handle member, and a compressible member positioned between the handle member and a compression plate. The compressible member is coupled to a proximal end of a needle. Following the delivery of fluid to a vascular access port, the needle is removed by moving the handle member away from the base member, which collapses the compressible member, flushing fluid into the vascular access port to substantially replace a volume of the needle.

摘要： A needle device includes a body, a needle shield movable relative to the body, a needle at least partially arranged in the body, and a safety system that at least one of causes the needle shield to move to an extended position when activated by a user, releasably retains the needle shield in a retracted position after the user moves the needle shield to the retracted position, prevents a user from triggering the device, locks the needle shield in a fully extended position, prevents the needle shield from being retained in a retracted position after a user moves the needle shield towards the retracted position, non-releasably retains the needle shield in a fully extended position after being activated by a user, and utilizes two separate re-use prevent mechanisms. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
