The utility model discloses a solve the above-mentioned problem that current disposable syringe needle exists, designed a disposable syringe needle that possesses and prevent the reutilization function, include: a needle seat, a needle tube and a protective sleeve; the needle seat comprises bases at two ends, a connecting part and a waist part between the bases and the connecting part; the connecting part fixes the tail part of the needle tube, and the protective sleeve is sleeved on the waist part and the outer side of the needle tube; the tube wall of the needle tube close to the connecting part is provided with a through hole and is sealed by a sealing adhesive tape.
Preferably, the sealing tape is provided with a sealing material in the same size as the through hole in the center.
Preferably, the sealing block material is one of a foaming material, rubber and plastic.
Preferably, the number of the through holes is one or two.
Preferably, the number of the through holes is two, and the through holes are linearly distributed along the axis of the needle tube or axially symmetrically distributed according to the axis of the needle tube.
Preferably, the aperture of the through hole is 1/2-3/4 of the diameter of the needle tube, and the distance between the through hole and the connecting part is 0.2mm-1 mm.
The utility model discloses a set up the through-hole in needle tubing root one side to the use is sealed the sticky tape and is sealed, enables medical staff and tears according to operation requirement after the use and seals the sticky tape, can not only distinguish the syringe needle that has used, can also be because on the needle tubing not seal the sticky tape and can't realize normal injection and scrap the syringe needle, realized preventing the purpose of secondary use, improved medical safety factor, compare in the market general syringe needle product and have certain advantage.
