Description

Technical Field

[0001] This utility model belongs to the field of intravenous infusion protective equipment technology, and specifically relates to a child intravenous infusion fixation protective equipment. Background Technology

[0002] When children receive intravenous infusions, an indwelling needle will be inserted as needed to reduce punctures and minimize harm to the child.

[0003] Currently, Chinese utility model patent CN220801643U discloses a hand fixation device for intravenous infusion in children. However, when administering intravenous infusions to children's hands, due to their natural restlessness, the indwelling needle is easily dislodged when their hands and fingers bend and move. Nurses often need to perform the venipuncture again, which increases both the child's pain and the workload of medical staff. Furthermore, the indwelling needle is directly exposed without protection, and when the child moves, it can easily be pulled by bedding or other objects on the bed, causing secondary injury and potentially leading to bleeding or swelling at the puncture site. Utility Model Content

[0004] The purpose of this utility model is to provide a child intravenous infusion fixation brace, which has the advantages of limiting the child's palm, reducing the risk of indwelling needle dislodgement, and protecting the indwelling needle from being touched by foreign objects.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pediatric intravenous infusion fixation brace, including a fixing hand plate, a finger plate being bolted to one end of the fixing hand plate, a finger retainer being welded to the top of the finger plate, an end plate being provided at the end of the fixing hand plate away from the finger plate, an L-shaped retainer being welded to one side of the end plate, a binding strap being fixedly connected to the side of the end plate away from the L-shaped retainer, and a retaining hole being opened at the end of the binding strap away from the end plate.

[0006] By employing the above technical solution, the child's hand is placed on a fixed hand plate, and finger retainers limit the movement of the finger joints. This prevents the child from directly bending their palm and finger joints, keeping them flat on top of the fixed hand plate and finger plate, thus limiting the child's hand position and reducing the risk of the indwelling needle dislodgement. A sliding arc plate slides across the surface of the fixed arc plate, allowing it to reach the top of the child's palm, where it is secured by tightening the fastening bolts. This effectively protects the indwelling needle by covering the child's hand, preventing it from being touched by external objects and improving the safety of indwelling needle use.

[0007] The present invention is further configured such that: a fixed arc plate is welded to the top of the fixed hand plate near the end plate, a sliding arc plate is slidably sleeved on the surface of the fixed arc plate, and limiting sliders that are slidably connected to the fixed arc plate are welded to both sides of the inner surface of the sliding arc plate, and a fastening bolt that is snapped into the fixed arc plate is threaded through the top of the sliding arc plate near the end plate.

[0008] Using the above technical solution, the sliding arc plate slides to the top of the child's palm, thereby covering the child's palm to protect the indwelling needle and prevent it from being touched by foreign objects.

[0009] The present invention is further configured such that: an extension hand plate is welded to one end of the end plate near the fixed hand plate and is slidably connected to the fixed hand plate; an insertion rod is slidably connected to one end of the extension hand plate away from the end plate and near the L-shaped locking rod; an insertion hole is opened on one side of the fixed hand plate near the L-shaped locking rod for slidably inserting into the insertion rod; and a spring is fixedly connected to the extension hand plate on one side of the insertion rod away from the insertion hole.

[0010] Using the above technical solution, since the arm becomes thicker towards the back, the end plate can be slidably adjusted at one end of the fixed hand plate. When the child's arm is thin, the end plate can be slid and adjusted backward to ensure the stability of the strap binding the child's arm.

[0011] The present invention is further configured such that: a concave-convex portion is provided on the side of the top of the fixed hand plate near the finger plate.

[0012] By adopting the above technical solution, by creating concave and convex parts on the top of the fixed hand plate, it can better adapt to the concave and convex parts of the palm, thereby fitting the palm and reducing discomfort to the palm over a long period of time.

[0013] The present invention is further configured such that: the top of the fixed hand plate near the concave and convex parts is provided with a clearance groove that works in conjunction with the sliding arc plate.

[0014] By adopting the above technical solution, the sliding arc plate can slide on both sides of the protruding position of the concave and convex parts through the avoidance groove, thus preventing interference with the movement of the sliding arc plate.

[0015] The present invention is further configured such that anti-slip pads are adhered to the top of both the fixed hand plate and the extended hand plate.

[0016] By adopting the above technical solution, the friction between the hand and the fixed hand plate and the socket is increased, thereby improving stability.

[0017] The present invention is further configured such that both the fixed hand plate and the extended hand plate have ventilation holes inside.

[0018] The above technical solution facilitates ventilation of the contact surfaces between the hand and the fixed hand plate and socket, preventing the interior from becoming too stuffy.

[0019] The present invention is further configured such that a straight groove is provided on the side of the top of the sliding arc plate away from the fastening bolt.

[0020] By adopting the above technical solution, the infusion tube can be embedded inside the straight groove, thereby avoiding compression of the infusion tube.

[0021] The present invention is further configured such that: the inner surface of the card hole is provided with a metal ring that is engaged with the cable tie.

[0022] The above technical solution protects the inside of the card hole from friction with the L-shaped card rod, preventing internal damage.

[0023] The present invention is further configured such that: a positioning rod that is slidably connected to the insertion rod is welded to the side of the extension hand plate near the insertion rod, and the spring is sleeved on the surface of the positioning rod.

[0024] The above technical solution is used to position the sliding of the insertion rod and improve the stability of the locking mechanism.

[0025] In summary, this utility model has the following beneficial effects:

[0026] 1. By placing the child's hand on the fixed hand plate, the finger clasps limit the movement of the finger joints. This prevents the child from directly bending their palm and finger joints, keeping them flat on top of the fixed hand plate and finger plate, thus limiting the movement of the child's hand and reducing the risk of the indwelling needle dislodging;

[0027] 2. By sliding the sliding arc plate on the surface of the fixed arc plate, the sliding arc plate can slide to the top of the child's palm and be fixed by tightening the fastening bolt. This protects the indwelling needle by covering the child's palm, preventing it from being touched by foreign objects and improving the safety of indwelling needle use. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Example 1:

[0035] refer to Figure 1 , Figure 2 A pediatric intravenous infusion fixation brace includes a fixation hand plate 1, a finger plate 2 attached to one end of the fixation hand plate 1, a finger retainer 3 welded to the top of the finger plate 2, an end plate 11 at the end of the fixation hand plate 1 away from the finger plate 2, an L-shaped retainer 6 welded to one side of the end plate 11, and a binding strap 4 fixedly connected to the side of the end plate 11 away from the L-shaped retainer 6. The binding strap 4 has a locking hole 5 at the end away from the end plate 11. By placing the child's hand on the fixation hand plate 1, the finger retainer 3 restricts the finger joints. This prevents the child from directly bending their palm and finger joints, keeping their hand flat on top of the fixation hand plate 1 and finger plate 2, thus restricting the child's hand and reducing the risk of indwelling needle dislodgement.

[0036] refer to Figure 1 The fixed hand plate 1 has a concave-convex part 16 on the top side near the finger plate 2. By providing the concave-convex part 16 on the top of the fixed hand plate 1, it can better adapt to the concave and convex parts of the palm, thereby fitting the palm and reducing discomfort to the palm over a long period of time.

[0037] refer to Figure 1 , Figure 2 The inner surface of the locking hole 5 is provided with a metal ring 21 that engages with the cable tie 4. This protects the interior of the locking hole 5 from friction with the L-shaped locking rod 6, preventing internal damage.

[0038] Brief description of usage: By placing the child's hand on the fixed hand plate 1 and passing their fingers through the finger retainers 3, the finger retainers 3 restrict the finger joints. Then, by pulling the strap 4, the retainer 5 is fastened to the L-shaped retainer 6, thereby fixing the extension hand plate 12 to the child's arm. When the child wants to bend their palm or fingers, because the fixed hand plate 1 is fixed to the bottom of the child's palm by the strap 4 and the finger retainers 3 and cannot move, and the finger retainers 3 restrict the finger joints, the child cannot directly bend their palm and finger joints. They can only keep their hand flat on top of the fixed hand plate 1 and the finger plate 2, thus avoiding any impact on the indwelling needle.

[0039] Example 2:

[0040] refer to Figure 1 , Figure 3 A pediatric intravenous infusion fixation brace includes a fixing arc plate 7 welded to the top of a fixing hand plate 1 near the end plate 11. A sliding arc plate 8 is slidably fitted onto the surface of the fixing arc plate 7. Limiting sliders 9, which are slidably connected to the fixing arc plate 7, are welded to both sides of the inner surface of the sliding arc plate 8. A fastening bolt 10, which engages with the fixing arc plate 7, is threaded through the top of the sliding arc plate 8 near the end plate 11. By sliding the sliding arc plate 8 on the surface of the fixing arc plate 7, the sliding arc plate 8 can slide to the top of the child's palm, and is fixed by tightening the fastening bolt 10. This effectively covers the child's palm, protecting the indwelling needle from contact with foreign objects and improving the safety of indwelling needle use.

[0041] refer to Figure 1 Each end of the fixed hand plate 1 near the concave-convex portion 16 is provided with a clearance groove 17 that cooperates with the sliding arc plate 8. This allows the sliding arc plate 8 to slide on both sides of the protruding position of the concave-convex portion 16 through the clearance groove 17, preventing interference with the movement of the sliding arc plate 8.

[0042] refer to Figure 1 A straight groove 20 is provided on the top side of the sliding arc plate 8 away from the fastening bolt 10. This allows the infusion tube to be embedded inside the straight groove 20, thereby avoiding compression of the infusion tube.

[0043] Brief description of usage: By sliding the sliding arc plate 8 against the surface of the fixed arc plate 7, the limiting slider 9 limits the sliding of the arc plate 8, allowing it to slide to the top of the child's palm. Simultaneously, tightening the fastening bolt 10 engages the sliding arc plate 8 with the fixed arc plate 7, further limiting its movement and protecting the indwelling needle by covering the child's hand. When the indwelling needle needs to be reused, the sliding arc plate 8 can be slid in the opposite direction to return to the top of the fixed arc plate 7, thus exposing the indwelling needle.

[0044] Example 3:

[0045] refer to Figure 1 , Figure 2 , Figure 3 A pediatric intravenous infusion fixation brace includes an end plate 11 with an extension plate 12 slidably connected to the fixed plate 1 at one end near the fixed plate 1. An insertion rod 13 is slidably connected to the extension plate 12 at one end away from the end plate 11 and near the L-shaped locking rod 6. The fixed plate 1 has an insertion hole 15 on the side near the L-shaped locking rod 6, which slidably engages with the insertion rod 13. A spring 14, bolted to the extension plate 12, is fixedly connected to the side of the insertion rod 13 away from the insertion hole 15. Since the arm becomes thicker towards the back, the end plate 11 can be slidably adjusted at one end of the fixed plate 1. When the child's arm is thin, the end plate 11 can be slidably adjusted backward to ensure the stability of the binding strap 4 around the child's arm.

[0046] refer to Figure 1 , Figure 2 , Figure 3 Anti-slip pads 18 are glued to the top of both the fixed hand plate 1 and the extended hand plate 12. This increases the friction between the hand and the fixed hand plate 1 and the socket 15, thus improving stability.

[0047] refer to Figure 1 , Figure 2 , Figure 3 Both the fixed handplate 1 and the extended handplate 12 have ventilation holes 19 inside. This allows for ventilation of the contact surfaces between the hand and the fixed handplate 1 and the socket 15, preventing the interior from becoming too stuffy.

[0048] refer to Figure 3 A positioning rod 22, which is slidably connected to the insertion rod 13, is welded to the side of the extension plate 12 near the insertion rod 13. A spring 14 is sleeved on the surface of the positioning rod 22. This is used to position the sliding of the insertion rod 13 and improve the stability of the locking mechanism.

[0049] Brief description of usage: By pressing the insertion rod 13 to overcome the elastic force of the spring 14, the insertion rod 13 slides back into the extension hand plate 12. This allows the extension hand plate 12 to slide away from the fixed hand plate 1 by pulling the end plate 11, thereby adjusting the position of the strap 4. Simultaneously, the rebound force of the spring 14 causes the insertion rod 13 to slide outwards again, allowing it to slide into the insertion hole 15, thus locking and securing the extension hand plate 12. Since the arm becomes thicker towards the back, the end plate 11 can be slid and adjusted at one end of the fixed hand plate 1. When the child's arm is thin, the end plate 11 can be slid and adjusted backwards to ensure the strap 4 is securely tied to the child's arm.

[0050] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
