Catheter device comprising a levering member

A catheter device (1) having an axis A-A, a lower side (L) adapted to face a patient, and an upper side (U) opposite the lower side (L) adapted to face away from the patient,

• said catheter device (1) comprising a catheter (2) and a hypodermic introducer needle (3), the catheter (2) comprising an axially elongated housing (4) having a proximal open end (5) adapted to receive a coupling mechanism or a plug, said elongated housing (4) further comprising an internal passage (6), a connecting port (7) with an internal orifice (8) arranged on the upper side (U) of the catheter device (1), and protrusion members (15) on an outer surface of the proximal open end (5), said catheter (2) further comprising a flexible catheter tube (12) connected to the elongated housing (4), said flexible catheter tube (12) comprising a distal tip end (13) and a lumen (14), said lumen (14) being in fluid communication with the internal passage (6) of the elongated housing (4);
• the introducer needle (3) comprising a proximal head (16), a hollow needle (17) having a distal beveled tip (18), and an extended portion (19,29) connecting the hollow needle (17) with the head (16) and adapted to engage with the proximal open end (5) of the catheter (2) when the introducer needle (3) is inserted into the catheter (2), said head (16) comprising an axial channel (20) in fluid communication with an interior of the hollow needle (17), a grip plate (21) arranged on the head (16) and extending in a direction perpendicular to an axial direction, and an engagement member (22) arranged on the grip plate (21) and protruding distally from said grip plate (21),
• said catheter (2) and said introducer needle (3) being arranged such that when the introducer needle (3) is inserted into the catheter (2), the grip plate (21) is directed towards the upper side (U) of the catheter (2) and aligned with the connection port (7), and wherein the protrusion members (15) on the proximal open end (5) of the catheter (2) are adapted to engage with the engagement member (22) on the grip plate (21) to prevent the introducer needle (3) from rotating around the axis A-A in relation to the catheter (2),
• the catheter device (1) further comprising a levering member (23) adapted to be removably attached to the catheter (2) and further adapted to motion the catheter (2) from a retracted proximal position to an advanced distal position in the axial direction in relation to the introducer needle (3), wherein, in the retracted proximal position, the beveled tip (18) of the introducer needle (3) protrudes from the distal tip end (13) of the catheter tube (12),
• and wherein, in the advanced distal position, the beveled tip (18) of the introducer needle (3) is hooded by the catheter tube (12),
• said catheter device (1) further comprising visual and/or tactile indicators on the grip plate (21) and/or on the extended portion (19, 29) to indicate at least one of
• a) the catheter (2) being advanced a distance d, said distance d corresponding to a length of the beveled tip (18) of the introducer needle (3), and
• b) the catheter (2) being advanced a distance D, said distance D corresponding to a distance greater than the length of the beveled tip (18) of the introducer needle (3).
