Finger Squeezing Device hopes to improve Capillary Refill Time Tests.

Capillary refill time is usually evaluated in the following manner. Doctors put pressure on the fingernails and then observe the manner in which the skin turns from white to red.

Doctors also use this method to evaluate hydration in patients. This method is especially helpful in children who are not in a position to express themselves to ascertain if their hydration levels are okay.

Yet, this system is not without drawbacks as there is a difference in the each patient's skin tone and refill times.

A prototype system has been designed by Bodkin Design and Engineering with a view to standardizing these tests. This new system comes with a squeezer to pinch a finger and optical sensors which evaluate the manner in which the skin tone changes. This can effectively make a difference in improving Diagnostic Accuracy for Dehydration in Young Children.
