    摘要： A self-blunting needle medical device comprises a needle cannula (18) fixed to a hub (20) having a receiving structure therein such as ferrule (22) and a movable blunting member (14) movably received within the cannula (18). Ferrule (22) defines a sleeve bore (38) extending therethrough, within which both the cannula (18) and the movable member (14) can be received and which establishes a coaxial relationship between them. The ferrule (22) defines a first guide surface (40) for directing the blunting end (14a) of the movable member (14) into the central bore of the cannula (18) during assembly. A second guide surface (42) performs the function of guiding the proximal end (18b) of the cannula (18) into ferrule (22) for mounting therein. Typically, the cannula (18) has a tissue puncture tip (18a). When the movable member (14) is retracted into the cannula (18), the puncture tip (18a) is exposed for use, e.g., injection into tissue. The movable member (14) is then moved to an extended position in which blunting end (14a) projects beyond the puncture tip (18a), to render the device safe with regard to subsequent accidental needle sticks.

    摘要： The present invention relates to a self-blunting blood collection needle (55) in which a blunting member (26a) is deployed upon withdrawal of a blood collection tube (56a) from the tube holder (e.g., 136), to blunt the needle (22) and so safeguard the patient and the technician from inadvertent needle sticks. The blunting member (26a) is retracted to re-sharpen the needle (22) when a subsequent collection tube is inserted into the holder (136). The deployment and retraction of the blunting member (26a) is accomplished with a mechanism (142) that is responsive to the insertion and withdrawal of the blood collection tube (56a) to retract and deploy the blunding member (26a) accordingly. One feature of the present invention is that the mechanism (142) effects blunting and re-sharpening of the needle without requiring that the technician manipulates the mechanism in a manner different from that of conventional, non-blunting collection needles. Four mechanisms are disclosed: a rack and pinion mechanism (42); a cylindrical cam mechanism (142); a lever mechanism (242) and a reversing strap mechanism (342).

    摘要： A needle assembly includes a needle component (10) and a blunting component (26), the needle component (10) containing a needle cannula (12) mounted in a housing (16) which defines a fluid chamber such as a fluid chamber (20). The blunding component (26) contains a non-perforated, open-ended blunting probe (28) mounted in a shuttle (30). The needle cannula (12) and the blunting probe (28) are disposed telescopically one within the other without obstructing flow through the needle passageway, and are movable between a sharpened configuration and a blunted configuration. The blunting member (26) is configured to permit the open end of the blunting probe (28) to provide flow access to the fluid chamber (20) in the housing (16).

    摘要： A needle assembly includes a needle member (10) and a blunting member (26), the needle member (10) containing a needle cannula (12), the needle cannula (12) having a puncture tip (14) and having a needle passageway therethrough. The blunting member (26) contains a blunting probe (28) having a blunt end (28a). The needle cannula (12) and the blunting probe (28) are disposed telescopically one within the other without obstructing flow through the needle passageway, and are movable between a sharpened configuration in which the puncture tip (14) of the needle cannula (12) is exposed and a blunted configuration in which the blunt end (28a) of the blunting probe (28) extends beyond the puncture tip (14) to blunt the needle assembly. The assembly may be combined with an accessory device (such as a catheter hub, guide wire, etc.) to produce an apparatus that is lockable in a blunted configuration and that can be released by the associated accessory, or may be configured to be released by manual manipulation.

    摘要： A self-blunting needle assembly (12) comprises a hollow needle, which may be of conventional construction having a needle mouth (16) and a needle shank (14) terminating in a puncture tip, has mounted within it a blunting member including an elongate probe (40) which slidably fits within the bore (34) of the needle shank (14). The probe (40) terminates in a distal tip (40a) which is initially positioned short of the puncture tip (32) of the needle so as not to interfere with injection of the needle either into a patient or into a connecting device. After injection, the blunting member is advanced to an extended position in which its distal tip (40a) protrudes beyond the puncture tip, thereby effectively blunting the needle. This protruding probe disables the needle from a re-use and blunts it sufficiently to prevent or greatly reduce accidental needlestick wounds. A mechanical extension member, such as a pin or fluid flowing through the needle may be used to advance the blunting member to its extended position.
