Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to low resistance disposable aseptic syringe needle.
Background
The needle seat of the traditional injection needle is integrally conical, and four ridge-shaped bulges are arranged outside the needle seat. When the injection needle is separated from the injector, the injector is not easy to hold and feel uncomfortable.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a low-resistance disposable sterile injection needle which has simple structure and reasonable design and is convenient to hold between the fingers.
In order to solve the above problem, the utility model discloses the technical scheme who adopts as follows:
the utility model provides a low resistance disposable aseptic syringe needle, includes cylinder and syringe needle, the one end of cylinder is equipped with the connector, just be equipped with in the connector with the fluid hole of the inside intercommunication of cylinder, the connector be equipped with a plurality of draw-in grooves on the surface, just the draw-in groove is followed the length direction of connector sets up, the one end of draw-in groove set up in the tip of connector, the one end of syringe needle is equipped with and is used for the cover to establish cutting ferrule on the connector, the cutting ferrule includes connecting portion and handheld portion, be equipped with on the inner wall of connecting portion with the fixture block that the draw-in groove cooperateed and connects, the top and the bottom of handheld portion all are.
Further, the width of the end, far away from the bottom of the connector, of the clamping groove is smaller than the width of the end, located at the bottom of the connector, of the clamping groove.
Furthermore, the fixture block is of a rectangular structure, and the width of the fixture block is equal to the maximum width of the clamping groove.
Further, the connecting portion is of a cylindrical structure, the handheld portion is of a spherical structure, and the diameter of the connecting portion is smaller than that of the handheld portion.
Compared with the prior art, the beneficial effects of the utility model reside in that: insert the draw-in groove through the fixture block and can make the syringe needle firmly install on the cylinder, and when separating syringe needle and cylinder, just can easily take off the syringe needle through grabbing handheld portion, reduce the separation resistance between cutting ferrule and the connector, made things convenient for medical staff to hold between the fingers the syringe needle widely through handheld portion, increased the comfort level of feeling.
