Description

A spiral needleless blood collection device

technical field

The utility model relates to the technical field of medical equipment, in particular to a helical needle-free blood collection device.

Background technique

The clinical use of indwelling needles can reduce the pain and fear of injections caused by repeated venipuncture, reduce the patient's anxiety, facilitate clinical medication, rescue medication for emergency and critically ill patients, reduce the workload of nurses, and reduce the number of patients. Pain, so intravenous indwelling needles are widely used in clinic. In the face of this special group of patients, the length of indwelling intravenous indwelling needles and the comfort of patients have become the most concerned issues for nurses and their families, and are also the sign of successful use of indwelling needles and the premise of promotion .

"Needle stick injury" refers to accidental injuries caused by sharp medical instruments, such as injection needles, suture needles, various puncture needles, surgical blades, etc., resulting in deep skin damage and bleeding. In recent years, with the strengthening of people's awareness of occupational protection, needle stick injuries have been paid more and more attention as an occupational injury caused by occupational exposure.

However, the current situation of clinical acupuncture injury is not optimistic, and the reporting system after acupuncture injury is still unsatisfactory. According to the U.S. Blood Exposure Prevention and Control Network System, nurses have the highest rate of needle stick injuries among all medical personnel for many years, accounting for 45% of medical personnel in 2002 and 37.8% in 2003. A questionnaire survey conducted by Chinese scholars on 1075 nurses in 2003 showed that the incidence of needlestick injuries was 80.6%, which was similar to foreign reports. The average annual per capita needlestick injury was 3.5 times, and 866 nurses had 3780 needlestick injuries in one year, of which Contaminated needle sticks accounted for 60%.

However, in the prior art, to draw blood with an indwelling needle is to directly tie a blood collection needle on the indwelling needle connector, which reduces the secondary puncture of the patient, but the risk of needle stick injury is relatively high.
