    摘要： A disposable sterile retracting blood taking needle consists of an end cover, a protective sleeve, a needle guard, a needle, a needle hub, a core rod. An outer sleeve, a piston, a sheath and a blood taking needle. The piston is arranged in a clamping groove of the core rod; the outer sleeve is sleeved on the core rod and the piston; the piston and the outer sleeve are in interference fit; inner holes of the needle, the needle hub, the core rod and the blood taking needle are communicated; the core rod and the outer sleeve are made of transparent materials; blood backflow is judged by blood flowing in a passage in the core rod; and after blood taking is completed, a medical worker presses a blood taking position of the blood taking needle with one hand, presses the outer sleeve with a finger of the other hand and pulls the needle guard to move back with other fingers of the other hand, so that a snap ring of the core rod enters a slot of the outer sleeve and is locked, and the blood taking needle is hidden in a cylinder of the outer sleeve, and thus the aim of safety is fulfilled.

    摘要： The Invention comprises a body, an actuator pivotally connected to the body, and a retractable needle adapted to provide fluid communication between a patient and a fluid collection tube, typically a blood collection tube, attachable to the device. A significant feature of the subject device is a retraction cavity disposed inside the actuator that is manually positionable to receive a portion of the needle retraction assembly following removal of the blood collection tube. Retraction is initiated by depressing the forwardly extending end of the actuator relative to the body, thereby causing a retainer clip to release the needle holder, after which the needle holder and a part of the needle are propelled into the retraction cavity by expansion of a compressed spring. The needle is thereby withdrawn from the patient and into the housing, reducing the likelihood of accidental needle sticks and preventing reuse of the device.

    摘要： A retractable needle fluid transfer device is provided. The device includes a manually operable actuator for affecting retraction. Upon depressing the actuator, a spring displaces the needle rearwardly so that the contaminated needle is enclosed, thereby preventing inadvertent needle sticks. The device includes forward and rearward stops for impeding displacement of the needle after the needle is retracted. A seal prevents contaminants from entering the device after the needle is retracted. A safety sampling access port adapter for obtaining fluid samples from a fluid line is also provided. The sampling adapter includes a first end configured to cooperate with an access port attached to the fluid line. The sampling adapter further includes a collapsible socket configured to cooperate with a fluid container such as a vacuum tube. A needle assembly disposed within the housing of the sampling adapter is operable to pierce the seal on the fluid container. After use, the socket is collapsed to prevent contact with the contaminated needle.

    摘要： A retractable safety needle assembly is provided. The needle assembly includes a tubular outer body, a retraction assembly contained with the outer body and a biasing element for applying a retraction force therebetween. The retraction assembly includes a cannula having an intravenous puncture tip and a non-patient puncture tip at opposing ends. In a first position, the intravenous puncture tip extends from a first end of the tubular outer body. The retraction assembly is adapted for movement within the tubular outer body from the first position to a second position in which the intravenous puncture tip and the non-patient puncture tip are contained entirely within the tubular outer body and are offset from a general axis defining the outer body.
