[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0021] Please refer to Figures 1 to 3 , a fixing device for an intravenous infusion catheter, comprising:

[0022] A fixing plate 1, a Velcro is provided at the bottom end of the fixing plate 1, a first limiting groove 11 is provided on the fixing plate 1, the opening of the first limiting groove 11 is facing the opposite direction of X, a second limiting groove 12 is provided on the fixing plate 1 and is connected to the inner wall of the first limiting groove 11X, a third limiting groove 13 is extended outwardly on the inner wall of the second limiting groove 12Y, and a blind hole 111 is provided on the inner wall of the first limiting groove 11Y;

[0023] An elastic member 2, the elastic member 2 is connected to the inner wall of the first limiting groove 11Y in the opposite direction;

[0024] A first abutment plate 3, the first abutment plate 3 is connected to one end of the elastic member 2 in the Y direction;

[0025] A limiting column 4, the limiting column 4 is movably connected to the blind hole 111 along the Y direction, and a second stop plate 41 is provided at one end of the limiting column 4 close to the first limiting groove 11;

[0026] A driving member is used to drive the limiting column 4 to move.

[0027] In the above embodiment, the outer wall of the heparin cap is pressed against the first abutment plate 3 and placed in the first limiting groove 11, and then the driving member drives the limiting column 4 to move along the Y direction, so that the second abutment plate 41 at one end of the limiting column 4 presses against the outer wall of the heparin cap, and the heparin cap is fixed in the first limiting groove 11, the hand-held part of the scalp needle is aligned with the third limiting groove 13, and the rear side of the hand-held part of the scalp needle is placed in the second limiting groove 12, and then the Velcro on the fixing plate 1 is attached to the bed near the patient's hand.
