Flat to be provided with piston rod, the right end of piston rod is pierced by through hole and is fixedly connected with push plate, and the left end of piston rod is fixedly connected with piston,
The lateral wall of piston is bonded with the madial wall of syringe, and the left surface of piston is fixedly connected with gasket；The gasket and syringe
Left side between be provided with baffle ring, offer circular hole in the middle part of baffle ring；Blood sampling cylinder is provided between the baffle ring and syringe, is taken a blood sample
Cylinder is connected with the inside of syringe；Shank is communicated with the right side of the syringe, the left end of shank is communicated with syringe needle, is set on the outside of shank
Casing is equipped with, the left end of casing is provided with the protrusion to extend internally, is provided with spiral spring in casing, and the two of spiral spring
End is fixedly connected with raised and shank respectively；Sheath is provided with the outside of the syringe needle, one end of sheath is openend, sheath
The other end is anti-acupuncture end, and the sidewall thickness of sheath is gradually reduced from openend to anti-acupuncture end, and the thickness at anti-acupuncture end is more than
The thickness of sheath openend side wall.
Further, it is provided with anti-skid chequer on the lateral wall of the syringe.
Further, the gasket is conical structure.
Further, the baffle ring is an integral molding structure with syringe.
Further, the blood sampling cylinder is detachably connected with syringe.
Further, the shank is threadedly coupled with syringe.
Further, some ribs are provided with the lateral wall of the sheath.
Compared with prior art, the utility model is sealed the opening on baffle ring by gasket when not drawing blood,
Blood drawing chamber is sealed, so can prevent the external world from causing to infect, during use piston movement blood is directly drawn into blood sampling
In cylinder, it can so prevent pollutant from falling into, cause blood testing nonstandard, when syringe needle to be pierced into the skin of patient, pass through
Revoling tube adjustment syringe needle is pierced into the depth of skin, reduces human body pain, while spiral spring is set in casing, even if stripped thread
The piercing depth of syringe needle can also be adjusted, while the sidewall thickness of sheath is gradually reduced, in the case where not influencing protective effect
The dosage of elastomeric material, saves cost, rib prevents sheath sidewall thickness is too small from influencing sheath needed for can also greatly reducing
Straightness.
