BLOOD, BLOOD SUBSTITUTE OR INFUSION SOLUTION LINE Russian patent published in 2015 - IPC A61M39/10 A61M39/12 A61M39/00 A61M1/34 

FIELD: medicine.

SUBSTANCE: line comprises at least one resilient-elastic connecting tube, and at least one connector used for coupling to external devices and mounted at the end of the tube. Each connector is made of a rigid polymeric material comprises at least one hollow cylinder with a lead-in cone and coupled to the connecting tube to form a tight non-adhesive mechanical connection set by coupling an internal surface of the connective tube to an external surface of the cylinder. An external diameter of the connector exceeds an internal diameter of the connecting tube by 0.1÷1 mm, whereas a length of the cylinder makes from 3 to 20 mm.

EFFECT: higher safety and lower toxicity by avoiding the use of adhesives for coupling the connecting tubes to the connectors, simplifying the manufacturing procedure of the device, as well as increases ease of use of the finished device by the simple tube connection to external devices.
