Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functional, method, or structural equivalents and substitutions made by these embodiments are within the scope of the present invention.

In the description of the present invention, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, mechanically or electrically connected, or interconnected between two elements, directly or indirectly through intervening media, and the specific meaning of the terms may be understood by those skilled in the art according to their specific situation.

As shown in fig. 1 and fig. 2, injection with keeping somewhere syringe needle, it includes needle body 1 and injection orifice 2, injection orifice 2 runs through needle body 1, and needle body 1 includes puncture part 11, connecting portion 12 and body 13, and fixed connection puncture part 11 and body 13 are distinguished at the both ends of connecting portion 12, and connecting portion 12 outer wall is regularly or irregularly equipped with a plurality of liquid outlets 3, liquid outlet 3 and injection orifice 2 intercommunication. The utility model discloses a set up a plurality of rules or anomalous liquid outlet 3 at connecting portion 12, supplementary infusion avoids because the infusion flow that various reasons lead to is less and block up, improves the absorption effect of infusion, has that flow is stable, patient absorbs effectually, is difficult for taking place the advantage of stifled needle.

Various embodiments of the specific structure of the liquid outlet 3 are possible, and the specific structure of each liquid outlet is described below.

Example one

As shown in fig. 3, the liquid outlet 3 has a circular or elliptical hole shape. The circular or elliptical hole-shaped liquid outlet 3 is convenient for discharging liquid from a patient body in multiple directions, the risk of blockage is reduced, and the flow reduction caused by movement is avoided.

In practical application, the liquid outlets 3 are regularly arranged around the outer wall of the connecting portion 12. The arrangement mode is convenient for processing and production. The liquid outlet 3 may be irregularly arranged on the outer wall of the connecting portion 12. Two kinds of structures can both realize supplementary play liquid, and all are diversified play liquid, have reduced the risk that liquid outlet 3 is whole to be blockked up, can guarantee the stability of infusion flow.

Example two

The liquid outlet 3 is in a slit shape. The slit-shaped liquid outlet 3 is convenient for multi-directional transfusion in the body of a patient, the risk of blockage is reduced, and the flow reduction caused by movement is avoided. The exit opening 3 may be a straight slit and/or a curved slit.

The liquid outlets 3 are regularly or irregularly arranged on the outer wall of the connecting portion 12.

As shown in fig. 4, the liquid outlet 3 is parallel to the axis of the needle body 1, and this structure is provided on the outer wall of the connecting portion 12. When the patient is moving, partial seam of the liquid outlet 3 can be opened due to the movement of the patient, so that the liquid outlet 3 can conveniently discharge liquid, liquid can be discharged in multiple directions, and the risk that the liquid outlet 3 is completely blocked is reduced.

As shown in fig. 5, the liquid outlet 3 is perpendicular to the axis of the needle body 1, and this structure is provided on the outer wall of the connecting portion 12. When the patient is moving, partial seam of the liquid outlet 3 can be opened due to the movement of the patient, so that the liquid outlet 3 can conveniently discharge liquid, liquid can be discharged in multiple directions, and the risk that the liquid outlet 3 is completely blocked is reduced.

As shown in fig. 6 and 9, the liquid outlet 3 forms an included angle with the axis of the needle body 1, and in specific implementation, the included angle is greater than 0 degree and smaller than 90 degrees. This structure is provided on the outer wall of the connecting portion 12. When the patient is moving, partial seam of the liquid outlet 3 can be opened due to the movement of the patient, so that the liquid outlet 3 can conveniently discharge liquid, liquid can be discharged in multiple directions, and the risk that the liquid outlet 3 is completely blocked is reduced.

EXAMPLE III

As shown in fig. 7, the liquid outlet 3 may be a combination of a slit shape and a hole shape. The slits and holes may be regularly or irregularly formed in the outer wall of the connecting portion 12. The slit-shaped discharge opening 3 may be a straight slit and/or a curved slit. The axes of the seam-shaped liquid outlet 3 and the needle body 1 can be arranged in parallel or vertically; the slit-shaped liquid outlet 3 can also form an included angle with the axis of the needle body 1, and the included angle is larger than 0 degree and smaller than 90 degrees in specific implementation. This combined structure is provided on the outer wall of the connecting portion 12. When a patient is in transfusion, the slit-shaped liquid outlet 3 can be opened due to the movement of the patient, so that the liquid outlet 3 can conveniently discharge liquid; and the hole-shaped liquid outlets 3 are combined and discharge liquid in multiple directions, so that the risk that the liquid outlets 3 are all blocked is greatly reduced.

As shown in fig. 8, the liquid outlet 3 is in the shape of a curved slit, and this structure is provided on the outer wall of the connecting portion 12. When the patient is moving, partial seam of the liquid outlet 3 can be opened due to the movement of the patient, so that the liquid outlet 3 can conveniently discharge liquid, liquid can be discharged in multiple directions, and the risk that the liquid outlet 3 is completely blocked is reduced. Fig. 8 is a schematic view, and a plurality of curved slits may be arranged regularly or irregularly, which is not illustrated in this embodiment.
