Description

Immobilization devices for limbs using intravenous indwelling needles for pediatric infusion

technical field

The invention relates to the technical field of infusion aids, in particular to a limb fixing device using intravenous indwelling needles for infusion in children.

Background technique

The venous indwelling needle is composed of a stainless steel core, a soft outer cannula and a plastic needle seat. When puncturing, the outer cannula and the needle core are pierced into the blood vessel together. When the cannula is sent into the blood vessel, the needle core is pulled out and only the soft outer sleeve An infusion tool in which the tube is left in the blood vessel for infusion, in order to reduce the number of venous punctures for long-term intravenous infusion, reduce the trauma to the vein, and improve the work efficiency of nurses. During the use of intravenous indwelling needles, adults have more The high degree of cooperation enables the intravenous indwelling needle to be better protected during use, but for children, there are many inconveniences, as follows:

Due to the lack of cognition and the discomfort caused by the indwelling needle to the limbs, the existence of the intravenous indwelling needle is relatively rejected. At the same time, because children are hyperactive by nature, the blood vessels are thin, and there are unconscious movements and curiosity about the indwelling needle and turning heparin The cap is easy to touch the arteriovenous indwelling needle, which may cause the indwelling needle to fall off, or cause trauma to the puncture port.

The puncture site is also different for children of different ages. Neonatal children generally choose the head, and preschool children prefer the back of the hand. At present, sterile transparent applicators are used for intravenous indwelling needles for tension-free fixation, and then they are fixed with adhesive tape. The method is relatively simple, and the protection is insufficient. The sterile transparent applicator and tape are easy to loosen and curl. At the same time, for preschool children who have punctured on the back of the hand, it is necessary to prevent their arms from sagging, and their fingers to be in a relaxed and straight state. The tight grip causes the skin to tighten, which can cause the needle to penetrate or loosen.
