  • Sheath for devices for injecting or withdrawing body fluids
    Patent number: 4943284
    Abstract: A device for sterile disposal of a device used to withdraw or inject fluids from or into the body comprising a tubular sheath disposed in a rolled-up fashion around the body fluid device proximate one end thereof. The length of the sheath is great enough to permit the sheath, when unrolled, to extend beyond the end of the body fluid device and for a sufficient distance to permit ready enclosure thereof and subsequent sealing off of the contents of the sheath. A method for using the device is also disclosed. The device is particularly useful in combination with a catheter of conventional design.
