Problems solved by technology

During the blood collection process, the staff needs to hold the blood collection needle to pierce it into the patient's blood vessel, and at the same time hold the vacuum negative pressure tube. In this case, it is difficult to free up the hands to fix the blood collection needle. It is easy to draw blood repeatedly due to operation failure, which not only increases the pain of the patient, but also prolongs the working hours of the staff, greatly reduces the efficiency of blood collection, and when pulling out the needle, it is necessary to place a cotton swab on the needle with one hand. At the mouth, the collection needle is pulled out with one hand, and the patient needs to press it with a cotton swab for a period of time to prevent the wound from bleeding, but this method brings inconvenience to the patient, and it will loosen if not paying attention, which increases the chance of infection patient recovery
