Device for securing a peripheral venous catheter
A device for securing a peripheral venous catheter, including a body comprising first and second fastening extremities and a connecting section that interconnects said fastening extremities, the latter feature a tubular shape and comprising corresponding first and second longitudinal grooves; a portion of the catheter may be inserted through said grooves to grasp the same in a folded manner, the connecting section comprises first and second portions extending between the longitudinal grooves, in such a way that the fastening extremities and the portions of the connecting section form a closed perimeter outline defining a hollow internal space adapted to be set between an open position and a closed position, where, the hollow internal space being open, the portion of the catheter may be inserted for the attachment thereof to the fastening extremities, and then secured to the latter when the hollow internal space is closed.

2 . The device according to claim 1 , wherein the first portion ( 1 . 31 ) of the connecting section ( 1 . 3 ) has a greater length than the second portion ( 1 . 32 ).
3 . The device according to claim 2 , wherein the two sub-portions ( 1 . 311 , 1 . 312 ) of the first portion ( 1 . 31 ) and the second portion ( 1 . 32 ) form a triangular-shaped closed perimeter outline.
4 . The device according to claim 1 , wherein the first recess-shaped part ( 1 . 51 ) of the tongue-and-groove joint ( 1 . 5 ) has a tubular geometry and the second projection-shaped part ( 1 . 52 ) has a cylindrical geometry.
5 . The device according to claim 1 , wherein the integral body ( 1 ) comprises a constant cross section throughout a length.
6 . The device according to claim 1 , wherein, in the second closed position of the hollow internal space ( 1 . 4 ), the first fastening extremity ( 1 . 1 ) and the second fastening extremity ( 1 . 2 ) comprise respective internal diameters equal to or less than an external diameter of the catheter ( 2 ), where the internal diameters of said first and second fastening extremities ( 1 . 1 , 1 . 2 ) generate a compression value on the catheter ( 2 ) that guarantees the immobilisation of said catheter ( 2 ) without strangling the catheter ( 2 ).
7 . The device according to claim 1 , wherein the first fastening extremity ( 1 . 1 ) and the second fastening extremity ( 1 . 2 ) are arranged raised on the second portion ( 1 . 32 ) of the connecting section ( 1 . 3 ).
8 . The device according to claim 1 , wherein the integral body ( 1 ) comprises a strap portion ( 1 . 6 ) adapted to secure the body ( 1 ) to a user.
9 . The device according to claim 8 , wherein the strap portion ( 1 . 6 ) is integrated into the integral body ( 1 ) as respective first and second side prolongations ( 1 . 61 , 1 . 62 ) of the second portion ( 1 . 32 ) of the connecting section ( 1 . 3 ).
10 . The device according to claim 9 , wherein the first and second side prolongations ( 1 . 61 , 1 . 62 ) extend below the second portion ( 1 . 32 ) of the connecting section ( 1 . 3 ).
11 . The device according to claim 8 , wherein the strap portion ( 1 . 6 ) comprises adjustment means ( 1 . 63 ) to adjust the integral body ( 1 ) to the user.
