Abstract Today, different medical needles are used in many diagnostic and treatment methods such as taking blood from a patient, injecting drugs, taking fluids, vaccination, insulin needles. The needles should be used only once due to the risk of infection. Medical needles used in the health field; it is not sharp enough and it is blunt. These features can cause pain to the patient, cause irritation of the skin, the needle may break inside the body, the needle may bend, the length of the needle tube may not be sufficient and many complaints are encountered. For these reasons, the suitability of the needles is important. Needle tests and investigations have been done to solve the problem. Our main goal in our work; have been subjected to penetration tests according to their properties in order to meet less problems during easy advancement / withdrawal of the needles in vessels / muscles of different types and diameters. The changes in the sinking force of the needle for different diameters and tip shapes were investigated. Thus, the level of pain the patient will have can be interpreted. The results obtained by the force applied at a certain speed with the compression test device were compared. In addition, the amount of microscopic changes before and after needle penetration was also examined. As a result of these tests, the sinking behaviors of disposable medical needles, which have a very important place in the health sector, will be examined and necessary comments will be made.
