Description

Safety indwelling lancet

technical field

The utility model relates to the field of medical instruments, in particular to a safety indwelling blood collection needle with dual functions.

Background technique

Venous blood collection is a common nursing operation in clinical nursing work, and it is also one of the main techniques to assist doctors in diagnosing and treating diseases. At present, most hospitals use disposable blood collection needles for blood collection, which are discarded immediately after blood collection. If the second blood collection is to be performed again, puncture and blood collection need to be performed again, which not only increases the pain of repeated puncture for patients, but also aggravates the pain. Workload of healthcare workers.

At present, there are two types of blood collection needles: disposable blood collection needles and indwelling needles with blood collection function. The blood collection needle mainly consists of the blood collection needle and the blood collection connection hose. When the needle is removed clinically, it is often found that there is a lot of blood remaining in the blood collection needle and the hose, and the blood collection needle is easy to puncture the medical staff, which increases the chance of occupational hazards for medical staff. The indwelling needle with blood collection function consists of a puncture blood collection component and an indwelling component. Although the blood collection function part and the infusion function part are separated, some needles with the puncture blood collection function need to be disassembled, and they need to be re-installed when they are used again. During the process of disassembly It is easy to stab medical staff and patients, resulting in secondary infection. Some needles with blood collection functions need to be re-covered, increasing the incidence of needle stick injuries.
