    摘要： A non-reusable retractable safety syringe is provided which has a hollow plunger and a seal member carried thereon. The provision of the plunger and the seal relative to the barrel permits the plunger, with sufficient strength, to carry applied pressure through the device during injection of a medicinal or other fluid into a patient, and yet permit the seal disposed at one end of the plunger to have maximum sealing integrity between the plunger and a cylindrical barrel disposed around the exterior of the plunger, to abate leakage of the liquid in a chamber within the barrel, as the plunger is manipulated from an expanded position to an expended position and thereafter to a third, or collapsed position. Designs for securing the seal relative to the plunger are disclosed. The syringe may be used to insert and/or withdraw fluid relative to the patient.

    摘要： A mechanical latching device is provided for threaded connections, such as those found in a medical syringe. The connections each have a thread profile with crest and root elements. At least one flexible finger or projection extends outwardly from within one of the root portions and an outwardly extending ridge is provided on the second threaded member extending from the ridge. Interference with normal threading movements between connection elements is abated, while resistance is provided to unthreading manipulations of the connections.

    摘要： Timing of movements of a spring between a stressed and a free state is delayed by dampening the spring movement through incorporation of a component having a restricted access diameter whereby frictional contact of the spring through the component will prolong the time required to move the spring between states to enhance control of the spring actuation.

    摘要： A non-reusable retractable safety syringe is provided which has a hollow plunger and a seal member carried thereon. The provision of the plunger and the seal relative to the barrel permits the plunger, with sufficient strength, to carry applied pressure through the device during injection of a medicinal or other fluid into a patient, and yet permit the seal disposed at one end of the plunger to have maximum sealing integrity between the plunger and a cylindrical barrel disposed around the exterior of the plunger, to abate leakage of the liquid in a chamber within the barrel, as the plunger is manipulated from an expanded position to an expended position and thereafter to a third, or collapsed position. Designs for securing the seal relative to the plunger are disclosed. The syringe may be used to insert and/or withdraw fluid relative to the patient.
