  • Apparatus and method for insertion of blood vessel catheters without blood loss
    Patent number: 5562630
    Abstract: The invention is to be used in conjunction with other medical devices that are designed to be attached to catheters. The use of the placement needle through the other components prevents the spillage of blood that usually occurs when catheters are inserted into blood vessels by acting as a sturdy guide for the pliable catheter tip and shaft while passing through a seal before penetrating a blood vessel. The catheter is pushed inside the vessel while the needle is removed and discarded. After the placement needle is removed from the unit blood fills the chambers but is trapped by the seal at the end of the injection site.Also disclosed is a method of using the invention.
