Dynamic slot limit sliding, slides and is fixed with steel needle on needle stand, and steel needle is through sliding needle stand, non-piercing one end of steel needle and blood transfusion hose
It connects；
Spring is installed, one end of spring is fixedly mounted on sliding needle stand, and the other end of spring is solid in the protective jacket
Dingan County is on protective jacket.
As the further scheme of the utility model, when the spring is not affected by compression or stretches, steel needle is completely in anti-
In sheath.
As the further scheme of the utility model, puncture one end and the limit disk of the steel needle are slidably connected, and limit
Disk is fixed in protective jacket.
As the further scheme of the utility model, the protective jacket is equipped with calotte in puncture one end of steel needle, calotte by
Soft material is made.
It is taken conveniently the utility model has the beneficial effects that the utility model when blood was collected, is held, and energy after blood sampling
It is enough quickly to take in steel needle in protective jacket, the case where steel needle stabs medical staff generation is prevented, while the steel after use
Needle, due to the protection of shield, is not susceptible to secondary injury in waste treatment, fool proof.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of puncture needle.
Specific embodiment
A kind of Anti-stabbing blood taking needle, as shown in Figure 1, including puncture needle 1, blood transfusion hose 2 and vacuum blood taking needle 3, it is described to wear
