  • Blood collection safety device
    Patent number: 6814707
    Abstract: A blood collection device includes a syringe assembly containing a slidable needle assembly within the cavity of a syringe body. The syringe body has a syringe top for receiving a seal assembly wherein the seal assembly is reversibly locked to the top of the syringe top. Within the insertable tube of the seal assembly is an occluding seal secured within the insertable cylinder with retaining rings. The occluding seal allows blood to flow from on end of a double pointed needle into a fully inserted collection tube. When the collection tube is removed the occluding seal keeps blood from flowing into the cavity of the insertable cylinder.
