DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figures 1-4 The infusion port fixing device in the embodiment has the advantage of good use effect.

[0023] Specifically, it comprises a sleeve frame 1;

[0024] A supporting arm 2 is arranged at one side of the sleeve frame 1;

[0025] A guiding frame 3 is detachably arranged at the top of the sleeve frame 1, and the guiding frame 3 is used for guiding the infusion needle;

[0026] Two clamping pieces 4 are respectively arranged at the two sides of the supporting arm 2 and are in close contact with the two sides of the sleeve frame 1;

[0027] A fixing piece 5 is arranged at the end of the supporting arm 2 and is used for fixing the two clamping pieces 4; after the two clamping pieces 4 are in close contact with the two sides of the sleeve frame 1, the two clamping pieces 4 can fix the infusion port; and the fixing piece 5 can fix the current state of the clamping piece 4.

[0028] In the embodiment, when it is needed to be used, the sleeve frame 1 can be sleeved on the outer wall of the infusion port first, then the user can pinch the two clamping pieces 4 by hand, when the two clamping pieces 4 are in contact with the two sides of the infusion port, the infusion port can be clamped and fixed in the sleeve frame 1, so as to prevent the infusion port from being deviated during the process of pricking the needle, which causes the needle tube to be difficult to be pricked into the infusion port, the fixing piece 5 is arranged to fix the current state of the clamping piece 4, so as to avoid the user from needing to apply force to the clamping piece 4 for a long time to maintain the state of the clamping piece 4, the guiding frame 3 can guide the infusion needle, so that the infusion needle can be better inserted into the infusion tube, and the guiding frame 3 is designed to be detachable, which can be replaced before each use, so as to prevent the possibility of cross infection.

[0029] Specifically, refer to Figure 2The guide frame 3 is in an inverted conical shape and has a hollow structure; a thread is arranged on the bottom of the outer wall of the guide frame 3, a threaded hole is arranged on the top of the sleeve frame 1, and the guide frame 3 is detachably connected with the sleeve frame 1 through the thread on the outer wall and the threaded hole on the top of the sleeve frame 1.

[0030] In the embodiment, the guide frame 3 can be removed or installed by screwing before and after use, so that one patient uses one set to avoid cross infection. The inverted conical design of the guide frame 3 can limit and guide the needle during insertion through the slope formed, so that the needle can be inserted into the infusion port more quickly and stably.

[0031] Specifically, referring to Figure 1 and Figure 3 The clamping part 4 includes two support plates 41 arranged on one side of the supporting arm 2, two rotating rods 42 rotatably penetrating through the two support plates 41 at both ends, a ratchet 43 and a force arm 44 sleeved on the outer wall of the rotating rod 42, a clamping sleeve 45 arranged on one end of the force arm 44, the clamping sleeve 45 being in contact with one side of the sleeve frame 1, and a spring I 46 arranged between the force arm 44 and the supporting arm 2.

[0032] In the embodiment, when the user pinches the force arm 44, the force arm 44 drives the rotating rod 42 and the ratchet 43 to rotate and press the spring I 46, and at the same time, the clamping sleeve 45 approaches one side of the sleeve frame 1. When the clamping sleeve 45 is in contact with the sleeve frame 1 and the side edge of the infusion port, the infusion port can be clamped and fixed in the sleeve frame 1 and the two clamping sleeves 45, and the spring I 46 can provide power for the reset of the two force arms 44.
