摘要： A cannula system (1) comprising a tubular housing (7) having a front and a rear end. A slider (6) is displaceably mounted inside the housing (7) between a front and a rear limit position. A tear end (5) of a cannula (3) is rigidly joined to the slider (6), the front end of said cannula being fitted with a front end (4) having a tip to pierce biological tissue and extending into the front end of the housing (7) when the slider (6) is in the rear limit position. Means are provided to move the cannula (3) back. A catheter (2) is affixed to the rear end of the housing (7) in the direction opposite the direction of piercing and extends at least in part through the slider (6) and into the cannula (3), preferably as far as the front end of said cannula, when the slider (6) is in its front limit position and the cannula (3) projects from the front end of the housing (7). This cannula system offers the advantage that the catheter can be sealed at the tip and also may consist of several ducts without incurring any danger of leaks anywhere.

摘要： The safety needle employs a manually operable actuator that can be depressed into a housing in order to release a spring-biased slider that carries a hollow needle. Upon release, the slider moves into a position to retract the needle over a blunt cannula so that the blunt cannula protects against cutting by the needle. An actuator guard may also be employed to prevent inadvertent actuation of the actuator.

摘要： A fluid collection apparatus is provided that includes a housing and a slide that is moveably supported by the housing. The slide has a cannula tab adapted to support a double ended needle and a plurality of connected segments that are moveably extending therefrom. Proximal movement of the slide causes the plurality of segments to contract in a configuration forming a shield about a proximal end of the double ended needle. The housing may define a slot in an outer surface thereof that is configured to receive a portion of the slide for guiding movement. The cannula tab can include a boss disposed adjacent a distal portion of the slide having the double needle mounted thereto. The cannula tab may include a segment member having a button mounted thereto which is disposed within at least a portion of the slot and slideably engages the slot to facilitate movement of the slide. The plurality of segments can include an end portion extending from a proximal end thereof. The end portion is disposed within a portion of the slot and cooperatively engages the slot to facilitate contraction of the plurality of segments.

摘要： An introducer catheter and needle guard assembly combination used with a peripherally inserted central catheter (PICC) is disclosed. The needle guard assembly includes a sliding needle hub for positively locking a needle in the needle guard assembly. The introducer catheter includes a tube portion and connector that can be divided into two halves. The needle guard assembly is secured to the introducer catheter and the extended needle and introducer catheter are inserted into the body of a patient. The needle and needle guard assembly can then be removed from the introducer catheter. A PICC line or other similar line can then be inserted through the catheter tube and into the patient. The tube portion and connector of the catheter are then divided into two halves so that the entire introducer catheter can be removed from the PICC line, or other similar line, that is inserted into the body of a patient.
