The problem that this invention addresses

Pediatric Arm Boards are used to secure intravenous accesses in the pediatric population.  These products are currently available in disposable or washable form that consists of a padded corrugated plastic board in different sizes.  In the clinical setting, the board is secured to an extremity, with an IV access, by wrapping it with tape or gauze. Then in order to prevent the pediatric patient from removing the IV access, the board and the IV site are wrapped again with gauze, linen and or more tape.  All this prevents a visual and tactile assessment of the intravenous site.  Furthermore, it wastes time and supplies.  Frequent IV site assessments are required in order to identify possible IV infiltrates.  An infiltrate occurs when an IV access becomes dislodged from the vein and fluids then accumulate in the tissues, potentially causing skin and tissue damage; in some cases, severe.  Not only dose this method of securing an IV access prevent visual and tactile assessment of the IV site, any attempt to assess the site could actually dislodge the IV access and therefore, may often be dangerously omitted.

     Units are available that would allow for a visual site check. These units can be quite complicated, consisting of several parts, training is required.  These types of boards can cost several times that of the standard arm board, and are generally not well received by staff. 




Description of the invention


An improved pediatric IV arm board which allows for visual and tactile inspection of an IV site without being removed

A simply constructed one piece design


The main function of the invention


To secure IV catheter to an extremity comfortably, with the least amount of restraint possible


To permit a visual and tactile inspection of the extremity and the and vein puncture site without removal of the device during IV therapy



Products will it replace

The standard arm board, and products used to secure such boards i.e. tape linen gauze wrap ect.


The significant advantages of the invention over presently available products/methods

The improved arm board will not require excessive taping and wrapping of limb   to secure the IV. The see through covering allows for a visual and tactile inspection of the IV site and the extremity, without having to un-tape, unwrap, and rewrap, re-tape the limb.  The unit is secured quickly and easily with a hook and loop type fastener. 



If a visual IV site check prompts further inspection of the extremity, the health care provider could also feel the limb for signs of swelling, tenderness, hardness, coldness without removing the device.  These are all symptoms of interference with circulation and are common signs of an IV infiltration.


This lightweight flexible covering allows for adequate air circulation keeping moisture away from the skin to prevent skin irritation and increase patient comfort.




Benefits of the invention   


·   Improves patient safety

·   Aids in the early detection of  I.V. infiltrates

·   Allows for visual site checks at just a glance

·   Allows for a tactile inspection of the extremity

·   Easy construction

·   Cost effective

·    Easy to use



When an IV infiltrates every second counts, the faster the infiltrate is recognized and the fluids are discontinued the less damage is done, especially if the infiltrate contains vesicant or irritant agents these agents will cause infection, ulceration, burning, hyper pigmentation, necrosis, prolonged pain, tissue sloughing, or loss of mobility.

 May also be used for

            IV Therapy for geriatrics and veterinary purposes
