Molded, plastic board with Velcro straps used to immobilize an infant while he is circumcised.

In the United States, baby boys are typically circumcised within days of their birth. So that doctors can more easily operate on infants, they use a device like the Circumstraint. During a circumcision, the doctor must first break the fused bond between the foreskin and the glans and then cut part of the foreskin. The Circumstraint restrains the baby boy from moving and writhing too much during the operation.

The advertisement for the device sadly claims: In less than 30 seconds, a nurse can immobilize the struggling infant securely in the correct position with Circumstraint. The immobilizer works on a proven principle of positive 4-point restraint. Soft, wide Velcro straps encircle the infant's elbows and knees, depriving him/her of leverage. The child is held safely and securely without danger of escape. Circumstraint's comfortable contoured shape positions the infant, hips elevated, perfectly presenting the genitalia.
