摘要:
A medical device including a barrel having an open first end and capable of supporting a needle at a second end of the barrel is provided and includes a lid releasably adhered to and overlying the open first end of the barrel in a fluid tight manner; and a pad secured to a surface of the lid such that the pad is disposed within a cavity of the barrel when the lid is adhered to the barrel, wherein the pad comprises a disinfecting solution.

This invention is a needle tip protective device (22). In one embodiment the needle tip protective device (22) includes a needle guard (41) that is slidably mounted on a hypodermic needle (10) having a needle tip (11) located at the distal end of the needle (10). The needle guard (41) contains a movable needle trap (41) that is biased against or toward the hypodermic needle (10). The needle trap (41) advances over the tip (11) of the needle, entrapping the needle tip (11) as the needle guard (41) is urged forward near the sharpened distal end of the hypodermic needle (10). A tether (24), or other limiting means, limits the forward movement of the needle guard (41) along the needle (10). In one embodiment, the needle guard is manually urged forward along the shaft of the needle by the user. In yet another embodiment, a spring, or other biasing means (19), is used to move the needle guard (41) along the shaft of the needle (10).

A needle assembly includes a transparent or translucent housing with a fluid inlet end, a fluid outlet end, a flashback chamber, and a venting mechanism therebetween. Substantially axially aligned inlet and outlet cannulas extend from the housing and communicate with the chamber. A sealable sleeve covers the external end of the outlet cannula. Relative volumes of the cannulas, the chamber, and the sleeve are selected to provide rapid reliable flashback indicative of venous entry with an internal vent positioned within the housing so as to divide the interior into first and second chambers, with the second chamber being adapted to maintain a negative pressure therein relative to the external environment so as to inhibit leakage of blood from the needle on withdrawal from the patient.

A blood collection assembly includes a housing and a cannula extending distally from the housing including a patient end, and a cannula shield removably engaged with a portion of the housing. The cannula shield is capable of shielding at least the patient end of the cannula, and includes a safety shield engagement. The assembly includes a pivoting safety shield engaged with a portion of the housing, which is transitionable from a retracted position in which the patient end of the cannula is exposed, to an extended position in which the patient end of the cannula is shielded by at least a portion of the safety shield. The safety shield includes at least one locking tab releasably engageable with the safety shield engagement, wherein the locking tab is fixedly engageable with a portion of the housing in the extended position.
摘要:
A safety device is presented for securely stowing a double sharp-ended needle. The device comprises a tubular adapter with a longitudinally-elongated channel. A needle holder is located in the channel to move from a distal orientation, in which one needle end projects from a distal adapter opening, and a proximal orientation, in which both needle ends are enclosed within the adapter body. A top plate transitions from a distal orientation, in which the plate is distal from a proximal adapter opening, and a proximal orientation, in which the top plate obstructs the proximal adapter opening. An actuator plate is attached to the adapter body to transition from a first position where the actuator plate retains the needle holder and top plate in distal orientations, and a second position where the needle holder and top plate move to proximal orientations.
