  • Vena puncture device and method
    Patent number: 4917101
    Abstract: A vena puncture device has a modified vena tube to provide for a spring loaded assembly within the vena tube. With the spring loaded assembly, the compressed spring of the vena puncture device provides for simplifed removal of a vacuum tube. Latches release the compressed spring assembly forcing the vacuum tube out of the vena tube and minimizing the pulling on the needle thereby easing the pain to the patient.
