Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of intravenous needle, more specifically, the utility model relates to a device for preventing intravenous needle from falling off. BACKGROUND

[0002] The intravenous needle is composed of a stainless steel core, a soft outer sleeve and a plastic needle base. During puncture, the outer sleeve and the needle core are inserted into the blood vessel together, and after the sleeve is sent into the blood vessel, the needle core is extracted, and only the soft outer sleeve is left in the blood vessel for infusion.

[0003] The working principle of the intravenous needle is based on the venipuncture technology and effective maintenance of the blood vessel passage. The medical staff first punctures the patient's venous blood vessel through the needle core, and when blood is seen (i.e. blood flows back into the transparent chamber of the needle core), it indicates that the needle core has entered the blood vessel. Then the outer sleeve is slowly pushed into the blood vessel along the needle core, and when the appropriate depth is reached, the needle core is extracted. At this time, the outer sleeve is left in the venous blood vessel, forming a relatively stable infusion passage.

[0004] The existing intravenous needle usually uses multiple adhesive tapes to fix it on the arm after the needle is inserted into the blood vessel. This fixing method is relatively simple, and when the patient's arm shakes, it is easy to cause the needle to fall off. Therefore, we propose a device for preventing intravenous needle from falling off. UTILITY MODEL CONTENT

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figs. 1 to 3As shown, this utility model provides a device to prevent the dislodgement of an indwelling intravenous catheter, including an indwelling intravenous catheter body 1. One end of the indwelling intravenous catheter body 1 is connected to a steel needle 2, which is used by inserting the steel needle 2 into a blood vessel. The other end of the indwelling intravenous catheter body 1 is connected to an extension catheter 3. Side plates 5 are rotatably connected to both sides of the indwelling intravenous catheter body 1. Each side plate 5 has a convex slot 6 on one side, and a convex insert plate 7 is inserted into the convex slot 6. A locking mechanism is provided between the convex insert plate 7 and the convex slot 6 on both sides. Each of the convex insert plates 7 has an elastic band 8 connected to its side wall. The elastic band 8 allows the strap 9 to be stretched easily, making it easy to fix on arms of different thicknesses. Each of the two elastic bands 8 has a strap 9 connected to one end. One strap 9 has a female Velcro 10 fixed to one side, and the other strap 9 has a female Velcro 11 fixed to the other side. The two straps 9 are tied to the arm, and the female Velcro 11 is then attached to the female Velcro 10. This allows the intravenous catheter body 1 to be tied to the arm for use.

[0019] The intravenous indwelling needle body 1 is fixed with a needle handle 4 on the top. The needle handle 4 has anti-slip texture on both sides of the side wall. The needle handle 4 allows the nurse to easily insert the steel needle 2 at one end of the intravenous indwelling needle body 1 into the blood vessel.

[0020] The indwelling intravenous catheter body 1 has adhesive tape 12 fixed on both sides of its bottom. The adhesive tape 12 can be used to attach the bottom of the indwelling intravenous catheter body 1 to the arm, thereby making the indwelling intravenous catheter body 1 more stable.

[0021] The locking mechanism includes an arc-shaped groove 13 and a rubber protrusion 14. The arc-shaped groove 13 is formed on the side wall of the convex slot 6, and the rubber protrusion 14 is fixed on the side wall of the convex insert plate 7. The rubber protrusion 14 is inserted into the arc-shaped groove 13. The locking mechanism can limit the convex insert plate 7. After the intravenous indwelling needle is used, the rubber protrusion 14 can be pulled out of the arc-shaped groove 13 by pulling the convex insert plate 7, and then the convex insert plate 7 can be pulled out of the convex slot 6. The bandage 9 can then be removed from both sides of the intravenous indwelling needle body 1, so that the bandage 9 can be reused next time, effectively avoiding the waste of resources.

[0022] The working principle and usage process of this utility model are as follows: The steel needle 2 is inserted into the blood vessel for use. Two straps 9 are tied to the arm, and the sub-hook and loop fastener 11 is attached to the main hook and loop fastener 10. The elastic band 8 allows the straps 9 to be stretched easily, so as to be easily fixed on arms of different thicknesses. In this way, the intravenous indwelling needle body 1 can be tied to the arm for use. Moreover, by pulling out the convex insert plate 7 from the convex slot 6, the straps 9 can be removed from both sides of the intravenous indwelling needle body 1, so that the straps 9 can be reused next time, effectively avoiding waste of resources.
