Patent attributes
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.
