The rigid plastic or metal needle inserted into the vein can damage the vein walls and increase the risk of vein rupture. This can lead to serious complications, especially in patients where finding a vein is difficult. 2. Needle Fear (Trypanophobia): A large percentage of patients experience needle fear. There are risks involved. Pediatric patients, the elderly, and individuals with needle phobia may experience stress and anxiety during procedures involving needles. This can hinder patient compliance with treatment, cause delays in treatment, and even affect the results of certain biochemical tests. 3. Needle Stick Risk and Infectious Diseases: Health risks associated with traditional needle systems... Medical personnel are at risk of needle stick injuries. As a result of needle stick injuries, healthcare workers are at risk of contracting bloodborne diseases (such as HIV, Hepatitis B and C). These accidents increase both the occupational safety of healthcare workers and the health risks of other patients. 4. Environmental Impacts and Medical Waste: Traditional intravenous devices are biologically... They are made from non-degradable materials. Plastic materials, especially PVC (polyvinyl chloride), are harmful to the environment as medical waste and cause serious environmental problems due to their non-recyclability. The disposal of medical devices after use leads to the accumulation of large amounts of waste in hospitals, and this waste harms the environment because it cannot decompose in nature. 35 This invention aims to overcome all the disadvantages mentioned above, to protect the health of employees, and on the other hand, to improve patient health and increase the comfort of treatment. 2 It is designed as a needleless intravenous catheter made from flexible and biocompatible material, offering a safer alternative to rigid needles. Furthermore, because the materials used are recyclable, it reduces medical waste, thus supporting environmental sustainability.
