Hand Support Splint

IV Hand Splint with Simultaneous Finger Plate Adjustment to Restrict Finger Movement

This technology is a hand support splint that restricts overall hand movement by attaching a glove—which leaves the fingernails and back of the hand exposed—to a base, and securing the fingers to individual finger plates. An adjustment mechanism rotates and moves multiple finger plates simultaneously to align them with the finger spacing.

Infants receiving IV therapy often move suddenly due to immature cognitive development, which poses a risk of the needle damaging blood vessels. Existing IV wrist splints only secure the palm and wrist, failing to restrict finger movement and lacking the ability to adjust for the child's hand size.

This technology adjusts the plate angle based on the rotation ratio between the female screw members on each finger plate and the male screw members on the body, while a single gear knob rotates two gears simultaneously to adjust finger spacing at once. Applicable to IV aids in pediatric wards and NICUs, it allows for visual monitoring of the fingernails and back of the hand while reducing IV needle dislodgement.

Key Features:

• A glove that leaves the fingernails and back of the hand exposed when worn, and a base to which the glove is attached to prevent movement of the gloved hand
• A body to which the palm portion of the glove is attached, and a plurality of finger plates to which the finger portions of the glove are individually attached
• An adjustment mechanism where the rotation angle of the finger plates changes in proportion to the rotation ratio of the first and second female screw members coupled to each finger plate and the first and second male screw members coupled to the body
• A gear knob rotatably coupled to the body to selectively and simultaneously engage with the first gear of the first male screw member and the second gear of the second male screw member
