The invention belongs to the technical field of
medical treatment articles and discloses an
artery-
vein puncture needle with novel structure and functions. The
artery-
vein puncture needle is providedwith an injection
pipe, a
thermal insulation cotton
cushion, a rubber sleeve, a thin thread, a protecting cover, a
syringe needle, a phosphorescent band and a plastic cavity, wherein the lower part ofthe injection
pipe is wound with the
thermal insulation cotton
cushion; the left end of the rubber sleeve is connected with the protecting cover through the thin thread; the
syringe needle is coveredwith the protecting cover; the protecting cover is wound with the phosphorescent band; and the right end of the rubber sleeve is connected with the plastic cavity through the thin thread. According to the
artery-
vein puncture needle, the protecting cover and the
syringe needle are connected together through the thin thread, so that the situation that a user is punctured by the exposed
syringe needle after the protecting cover is lost is prevented; the temperature of liquid in the injection
pipe is maintained by virtue of the
thermal insulation cotton
cushion, so that the situation that a patient feels uncomfortable when the medical liquid is too cold is prevented; the phosphorescent band is capable of emitting
light at night, so that a medical worker can conveniently find blood vessels; and the
syringe needle can be inserted into the plastic cavity so as to completely
discharge residual liquid after the transfusion, so that the situation that the
environmental health is influenced bythe residual liquid is prevented.
