How long does it take for a elastrator to work on humans?

An elastrator, commonly used in veterinary practice for livestock, is not recommended for use on humans. If the device were hypothetically applied, the rubber band would restrict blood flow, potentially leading to tissue necrosis over several hours to days. However, using an elastrator on humans is dangerous and illegal, as it can cause severe pain and medical complications. It is crucial to seek appropriate medical care for any necessary procedures.
