Description

Technical Field

[0001] This utility model belongs to the field of medical assistive device technology, specifically relating to an indwelling needle auxiliary fixation device suitable for children. Background Technology

[0002] Indwelling intravenous catheters, also known as intravenous cannulas, consist of a flexible catheter / cannulas that can be left in a blood vessel, and a stainless steel puncture guide needle. During use, the catheter and needle are inserted into the blood vessel together. Once the catheter is fully inside the vessel, the needle is withdrawn, leaving only the flexible catheter in place for intravenous infusion. The use of indwelling catheters reduces the pain and fear of injections caused by repeated venipunctures, alleviates anxiety for family members, facilitates clinical medication administration, and is useful for the emergency and resuscitation of critically ill patients. It also reduces the workload of nurses and minimizes patient pain. Therefore, indwelling intravenous catheters are widely used in clinical practice.

[0003] However, when children use indwelling needles, factors such as fear, hyperactivity, and excessive sweating can easily cause the indwelling needle to become loosely attached or curl at the edges, leading to needle displacement, bleeding at the puncture site, and a shorter indwelling time than expected. Currently, clinical nurses mostly use cotton mesh bags and self-adhesive elastic bandages for auxiliary fixation, but these methods have certain drawbacks. Mesh bags, due to their excessive elasticity, are prone to curling and lack good fixation, failing to provide adequate immobilization for active children. Self-adhesive elastic bandages are not breathable, causing sweating in summer and potentially leading to allergic reactions in children's delicate skin. Their opaque material makes it difficult for nurses to observe the puncture site, often requiring "windowing" or removing the bandage for inspection, which reduces adhesion after repeated removal and reduces utilization. Furthermore, this method only effectively fixes the needle itself, not the active hands. Therefore, this paper proposes a suitable indwelling needle fixation device for children to overcome these technical shortcomings. Utility Model Content

[0024] This specific embodiment is an indwelling needle auxiliary fixation device suitable for children, and its structural schematic diagram is as follows. Figures 1-6As shown, the bushing includes a bushing 1, with a limiting plate 8 placed inside the bushing 1. Elastic bands 9 are sewn onto both the front and rear sides of the bushing 1. A first limiting part 2 and a second limiting part 3 are sewn onto the left end of the side of the two elastic bands 9 away from the bushing 1, respectively. A third limiting part 4 and a fourth limiting part 5 are sewn onto the right end of the side of the two elastic bands 9 away from the bushing 1, respectively. An arc-shaped opening 201 is provided in the middle of the ends of the first limiting part 2 and the second limiting part 3 that are far apart from each other. Fixing components are provided on the left ends of both the front and rear sides of the bushing 1.

[0025] In practical use, the sleeve 1 has a certain degree of elasticity. The nurse can insert the limiting plate 8 into the sleeve 1 according to the size of the child's hand. The limiting plate 8 can be made of cardboard with a certain degree of rigidity. Then, the child's hand is placed on the sleeve 1. The first limiting part 2 is folded towards the back of the hand and fitted so that the arc-shaped opening 201 is located on the outside of the indwelling needle. Then, the second limiting part 3 is folded towards the back of the hand so that its arc-shaped opening 201 partially overlaps and is fixed with the first limiting part 2, thereby fixing the indwelling needle. In addition, after the ends of the first limiting part 2 and the second limiting part 3 that are away from the third limiting part 4 and the fourth limiting part 5 are fixed, they only limit the base of the fingers, thus avoiding limiting all four fingers and affecting the blood circulation of the fingertips. The elastic band 9 can extend the length of the first limiting part 2 and the second limiting part 3. To accommodate hands of different sizes; furthermore, the first limiting part 2 and the second limiting part 3 can be provided with a U-shaped opening facing to the right on the side near the corresponding elastic band 9, so that after the first limiting part 2 and the second limiting part 3 are folded and fixed, the base of the patient's thumb is located inside the U-shaped opening, allowing the thumb to move freely outside, thus enabling the first limiting part 2 and the second limiting part 3 to effectively fix the indwelling needle on the back of the hand; then the third limiting part 4 and the fourth limiting part 5 are folded and fixed in the same manner as described above; in this way, the first limiting part 2 and the second limiting part 3 can fix the indwelling needle and the hand, while the third limiting part 4 and the fourth limiting part 5 can fix the section of the arm near the wrist. Under the action of the limiting plate 8, the child's hand and arm are limited, preventing the child's hand from moving around.

[0026] In addition, the lower surface of the bushing 1 has an opening in the middle, which is connected by a hidden zipper 101. A limiting pad 7 is fixedly connected to the upper surface of the right end of the bushing 1. The hidden zipper 101 allows the bushing 1 to be opened, making it easy to place and remove the limiting plate 8. The limiting pad 7 can support and limit the child's arm near the wrist.

[0027] In addition, the liner 1 is made of a blend of medical cotton and polyester, and the top center of the limiting pad 7 has an arc-shaped groove. The limiting pad 7 is made of high-elastic sponge material. The liner 1, made of a blend of medical cotton and polyester, is elastic, breathable, and can be soaked in chlorine-containing disinfectant for disinfection, making it easy to reuse.

[0028] In addition, the first limiting part 2 is made of non-woven fabric. The first limiting part 2 is sewn to the third limiting part 4, and the second limiting part 3 is sewn to the fourth limiting part 5. Both the ends of the first limiting part 2 and the third limiting part 4 that are close to each other and the ends of the second limiting part 3 and the fourth limiting part 5 that are close to each other are provided with a gap 202. The first limiting part 2 is made of non-woven fabric, which has breathable and skin-friendly properties. The first limiting part 2 and the third limiting part 4 are connected, and the second limiting part 3 and the third limiting part 4 are connected, which makes it easy to quickly limit the child's hand.

[0029] Furthermore, the second limiting part 3, the third limiting part 4, and the fourth limiting part 5 are all made of polyester and have hollowed-out designs. The outer side of the first limiting part 2 near the arc-shaped opening 201 is fixedly connected to the first hook and loop fastener 203. The inner side of the second limiting part 3 near the arc-shaped opening 201 is fixedly connected to the first hook and loop fastener 301. The upper rear end of the third limiting part 4 is fixedly connected to the second hook and loop fastener 401. The upper inner end of the fourth limiting part 5 is fixedly connected to the second hook and loop fastener 501. The first hook and loop fastener 203 and the first hook and loop fastener 301 are bonded together to securely fix the back of the hand and the indwelling needle to the first limiting part 2 and the second limiting part 3. The second hook and loop fastener 401 and the second hook and loop fastener 501 are bonded together to limit the wrist and arm to the right end of the bushing 1 by the third limiting part 4 and the fourth limiting part 5, avoiding excessive wrist joint movement that could cause the indwelling needle to dislodge or shift.

[0030] In addition, both fixing components include two fixing straps 6. One end of the two fixing straps 6 is sewn to the bushing 1, and the other ends of the two fixing straps 6 are close to each other and sewn together to form an adhesive area. The upper surface of the adhesive area is fixedly connected to a third hook and loop fastener 601. Both sides of the lower left side of the bushing 1 are fixedly connected to a third hook and loop fastener 102. One end of the adhesive area of ​​two of the fixing straps 6 is passed through the other two fixing straps 6 and fixed to the bottom of the bushing 1, so that two of the fixing straps 6 can limit the first limiting part 2 and the second limiting part 3. The other two fixing straps 6 are then folded over again for fixing. The two fixing straps 6 avoid the thumb, allowing the thumb to move freely outside.

[0031] In addition, the ends of the two fixing straps 6 near the bushing 1 correspond to the first limiting part 2 and the second limiting part 3 respectively, and the third hook and loop fastener 102 corresponds to the third hook and loop fastener 601. By attaching the two third hook and loop fasteners to the third hook and loop fastener 102 on the lower surface of the bushing 1 respectively, the first limiting part 2 and the second limiting part 3 are further fixed, and it is also convenient to remove the fastener for disinfection.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
