Description
Technical Field
The patent of the utility model relates to the field of medical equipment, especially a venous blood taking needle.
Background
In clinical work, the nursing staff has more chances to directly contact with a patient, invasive operation is frequent, and the probability of needle stick injury of the nursing staff is objectively increased. The needle stick injury refers to an accidental injury of bleeding caused by pricking skin with various medical sharp instruments in medical work. Domestic and foreign researches show that the incidence rate of the needle-prick injury of nursing staff is far higher than that of other medical staff, and the nursing staff is a high-risk group suffering from the needle-prick injury. Venous blood collection technology, as a test that has been practiced for centuries, is commonly used in laboratory tests to aid in clinical diagnosis and health assessment, and is still one of the most common clinical invasive medical procedures until now. The nursing staff can not only directly contact the blood of the patient in the venous blood sampling process, but also has more blood volume and high pathogen concentration, so that the venous blood sampling process is very easy to cause blood infection diseases if a needle stick injury occurs. In 2017, Lihui of Hunan ya Hospital, Zhongnan university, was investigated about the puncture status of venous blood collection needles by Chinese nurses, and the puncture wound caused by blood collection accounted for 20.78%.
Moreover, a special tool for collecting blood standards of hemodialysis patients is lacked in the market, so that the work of collecting blood samples of the hemodialysis patients becomes complicated, the work efficiency is low, and the detection result is inaccurate; moreover, the blood specimen is often contaminated, the blood cells are damaged, and the nursing staff is easy to prick during the blood specimen collection process, so that the detection result is inaccurate.
Therefore, how to improve the detection result of venous blood collection is a technical problem which needs to be solved by the technicians in the field at present.
