Detailed Description

Combine the figure, a disposable intravenous transfusion needle of protection type, including the needle tubing body, the needle tubing body includes needle tubing 1, is located the needle handle 2 of 1 one side of needle tubing, be located the syringe needle 3 of 1 one end of needle tubing, the other end of needle tubing 1 can be dismantled and be connected with hose 4, the other end of hose 4 is connected with conical head 5, needle tubing 1 is equipped with the protective sheath 6 of upwards parcel syringe needle with the junction cover of syringe needle 3, protective sheath 6 can along 2 departments of needle handle turn over to the roll-down.

As a preferred embodiment of this embodiment, the protective sheath 6 is a straight tube body penetrating vertically, the protective sheath 6 includes a connecting section 6.1 sleeved on the top of the needle tube 1 and a folded section 6.2 disposed on the upper portion of the connecting section 6.1, a boundary between the connecting section 6.1 and the folded section 6.2 is provided with an edge line 6.3, one side of the folded section 6.2 is provided with a tearing strip 6.4 capable of being torn along the length direction thereof, one side of the folded section 6.2 away from the tearing strip 6.4 is provided with a buckle 6.5, and when the folded section 6.2 is folded downward, the buckle 6.5 is fastened to the hose 4.

As a preferred embodiment of this embodiment, the top of the tear strip 6.4 extends beyond the top of the folded-over section 6.2 to form an open end.

As a preferred embodiment of the embodiment, a T-shaped opening 6.6 is formed at the joint of the top of the folded section 6.2 of the protective sleeve 6 and the tear strip 6.4.
