摘要： The present embodiments provide for a syringe and a retraction plunger assembly configured to accept various retractable needle assemblies, which are capable of cooperating to provide a retraction safety syringe. In particular, the syringe includes a barrel and a retraction plunger assembly comprising a control unit attached to a plunger and releasably engaged to a housing, and at least one biasing means disposed within the plunger assembly. Upon completion of dose delivery via a retractable needle, the control unit disengages from housing and the biasing member retracts the plunger and a connected needle into the barrel. Various elements are configured to prevent further use of the syringe. The control unit can be used to control a rate of needle retraction.

摘要： A pneumatic retractable syringe has a plunger having an interior retraction lumen. The plunger and syringe barrel have cooperating locking elements so that the plunger is locked after use within the syringe barrel. After injection of medicament is completed, the needle is retracted into the lumen by compressed gas that is released from a gas cell within the syringe when the gas cell is ruptured just before the plunger reaches the end of its downstream path of travel.

摘要： An automatic mixing device, an actuating device removably mounted to the automatic mixing device and a retractable syringe having the automatic mixing device are provided. The actuating device has an initially compressed spring and a trigger member that initiates spring decompression to drive depression of a mixing plunger of the automatic mixing device. A seal located in the outer chamber is capable of axial movement upon depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in an inner barrel to a second position intermediate the apertures and vents in an outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in an inner chamber of the inner barrel. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.

摘要： A disposable syringe includes a needle assembly having a needle seat retained in a barrel by a grip member to fix a needle cannula, a tubular plunger movable in the barrel toward the needle seat during an injection course, and a coupling member having a retained shank in frictional engagement with the plunger, and an anchored portion disposed outwardly of the plunger to engage a rear anchoring portion of the needle seat when the coupling member is moved forwardly. When the plunger is moved further forward to cause the plunger to move relative to the coupling member, the retained shank is released to enable the needle assembly to retract into the plunger by means of a biasing member. A guiding sleeve is sleeved on the needle seat, and can be forced to extend between the needle seat and the grip member so as to decrease the frictional force therebetween for ensuring successful retraction of the needle assembly.

摘要： A hypodermic injection system with a retractable needle wherein the needle retracts within an interior cavity of a syringe plunger, such that the needle is confined within the plunger. A spring biases the needle rearwardly into the plunger, and a needle retainer releasably retains the needle against the bias of the spring. The plunger has a frangible end, which dissociates when the plunger engages the needle retainer, allowing the coiled spring to eject the needle into the interior cavity of the plunger. A body fluid sampling embodiment employs the same functional elements except the plunger is shorter and contains a linking that communicates with a vacuum container. The container allows fluid sampling and provides the structure to release the spring retracting the needle. The retractable needle embodiment is also employed with an insertion needle that guides a catheter tube below the skin of a patient and into the vein, and allows retraction of the insertion needle thereby avoiding accidental pricking of the health care worker by the insertion needle.

摘要： The safe syringe comprises a cylinder, a needle seat and a pusher plunger. The needle seat is firmly connected to the front inner side of the cylinder, the needle seat has on its bottom a first protruding piercing portion, a chamber with a positive pressure is formed between the bottom of the needle seat and the front end of the cylinder; the pusher plunger is a hollow rod having a chamber therein with a negative pressure, the rod has a second piercing portion on the outer wall on its front end, and a piston envelops the front surface of the rod and the outer wall. Thereby, when the plunger is pushed to the front end of the cylinder, the first piercing portion pierces and breaks the piston and the front surface of the rod, the second piercing portion pierces forwards through and cut out the bottom of the needle seat to make communication of the two chambers, thus the bottom of the needle seat is drawn into the plunger together with the needle by changing of pressure.
