If we start from the fact that this finger is least involved in any actions, then it is possible that the skin on his pad is indeed more tender than on others.

According to the rules, of course, disposable instruments are used. They are unpacked directly by the patient. So the person who came to donate blood can directly control the issue of security. Now there are special lancets that hide the needle inside the case. Usually they are used for blood sampling in small children (up to three years).
