[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, this embodiment provides a child pressure sore prevention safety indwelling needle, including an indwelling needle 1, an adhesive dressing is arranged below the indwelling needle 1, a positioning mechanism 5 is arranged below the indwelling needle 1, the positioning mechanism 5 is located on a side close to the indwelling needle 1 and has a syringe fitting groove 501, a slide groove 504 is opened on the upper surface of the positioning mechanism 5, a movable slider 506 is arranged inside the slide groove 504, the movable slider 506 is slidably connected to the slide groove 504, a movable rod 505 is installed above the movable slider 506, and a limit rod is installed on the upper end of the movable rod 505 502, the limiting rod 502 is rotatably connected to the movable slider 506 through the movable rod 505, one end of the limiting rod 502 is connected to the movable plate 507, an elastic rotating shaft is installed between the movable plate 507 and the limiting rod 502, an insertion rod 508 is installed on one side of the movable plate 507, the insertion rod 508 is clamped with the socket 510, a limiting pad 503 is installed on the upper surface of the positioning mechanism 5 at one end of the slide groove 504, the limiting pad 503 is fixedly connected to the positioning mechanism 5, and the limiting pad 503 is located on the side away from the limiting rod 502 and is provided with a socket 510.

[0024] like Figure 2-5 As shown, in this embodiment, an adhesive dressing is provided below the positioning mechanism 5, and the adhesive dressing includes: an adhesive layer 3, a dressing layer 4, a wing plate 2 is installed on one side of the indwelling needle 1, a spring 509 is connected between the limiting pad 503 and the movable slider 506, and the spring 509 is fixedly connected to the limiting pad 503 and the movable slider 506, a fleece-surface Velcro layer 401 is provided on the upper surface of the dressing layer 4, and a hook-surface Velcro is provided on the lower surface of the positioning mechanism 5 at the position corresponding to the fleece-surface Velcro layer 401.

[0025] The working principle of the utility model is as follows: when in use, the dressing layer 4 and the adhesive layer 3 are adhered as a whole to the position where the patient needs puncture, so that a small amount of blood can be absorbed during the use of the indwelling needle. After the positioning mechanism 5 is adhered as a whole to the top of the fleece-surface Velcro layer 401, the indwelling needle 1 is placed at the syringe fitting groove 501 on one side of the positioning mechanism 5, and the wing plate 2 on the outside of the indwelling needle 1 corresponds to the side close to the positioning mechanism 5, and the gap between the wing plate 2 and the indwelling needle 1 will correspond to the position of the slide groove 504 as a whole. After the movable plate 507 at the end of the limiting rod 502 is overall moved and unfolded, the limiting rod 502 is overall moved by the movable rod 505 to move the slider 506. After rotating upward, one end with the movable plate 507 is rotated toward the direction of the limiting pad 503, and the limiting rod 502 is pulled forward as a whole to drive the movable slider 506 to contract the internal compression spring 509 in the slide groove 504, driving the outermost end of the limiting rod 502 to exceed the position of the limiting pad 503, and then releasing the force on the movable plate 507, and inserting the insertion rod 508 on the outside of the movable plate 507 into the interior of the socket 510 as a whole, the limiting rod 502 cooperates with the limiting pad 503 to clamp and limit the gap between the indwelling needle 1 and the wing plate 2, so that the indwelling needle 1 can be limited, and at the same time, the wing plate 2 will not press on the skin for a long time to cause wear.
