Description

Dispensing needle

The technical field is as follows:

the utility model provides a pair of syringe needle dispenses belongs to the medical instrument field, especially relates to hospital's vein is used with medicine allotment.

Background art:

the medicine dissolving injector used in the existing transfusion medicine dispensing mode has unreasonable needle head design, and the penicillin bottle is used for packaging medicine for preparation, so that leakage and particle pollution are easily caused by puncturing the penicillin bottle and a large liquid rubber plug for multiple times; the application of the publication number CN202086793U discloses a dispensing needle head which limits the length from a needle tube to a needle seat and the distance from a side hole to the needle seat, and aims to solve the problem that the medicine liquid is completely discharged without needle return in the dispensing and suction process of a penicillin bottle; however, the problems that are not considered are: 1. for large liquid containers of a certain number of manufacturers, the bottle stoppers are thick, and the side holes cannot penetrate through the bottle stoppers, so that liquid medicine cannot be injected into the large liquid; 2. the needle tube is short, so that inconvenience is caused by pumping ampoule packaged water medicament, the needle tube cannot be used, and a plurality of inconveniences such as replacement of a dispensing injector is needed when various medicaments are dispensed; along with the popularization of the national centralized configuration center system for intravenous administration, the centralized dispensing brings strong requirements of special dispensing equipment and equipment, the equipment dispensing is easy to finish the preparation of medicines with large batches of simple compositions, and for the preparation of complicated compositions and sporadic medicines, the configuration period is long and the cost is high, so that the dispensing equipment more suitable for the static configuration center is provided as a part of an organic whole of a static configuration solution.

The invention content is as follows:

the utility model provides a replace current syringe needle that dispenses, realize all-round dispensing, both had xiLin bottle packing medicine allotment convenience, also did not reduce the suitability of ampoule packing medicine allotment simultaneously, was applicable to all big liquid packaging container, is the organic replenishment of the unable allotment medicine of equipment, is applicable to medical institution simultaneously and contains quiet all departments of joining in marriage the center and dispense. The utility model provides a dispensing needle comprises needle tubing, needle file, and the nearly needle file end diameter of needle tubing is big, and nearly needle point end diameter is little, links up by the step that excessive inclined plane formed, and the minor diameter part is equipped with the side opening, and the edge of the needle point is far away from the side opening is 4 + -0.5 mm apart from the distance L of step, 5 + -0.5 mm, 6 + -0.5 mm, 7 + -0.5 mm, 8 + -0.5 mm, 9 + -0.5 mm, 10 + -0.5 mm.

The utility model discloses a realize through following scheme:

description of the drawings:

FIG. 1 is a schematic view of a dispensing needle

FIG. 2 is a cross-sectional view of a dispensing needle

In the drawings

1. The distance between the needle tube 2, the needle stand L and the edge of the needle tip far away from the side hole and the step.

The specific implementation mode is as follows: the following description of exemplary embodiments refers to the accompanying drawings.

Example 1: a dispensing needle.

In the embodiment, a needle tube 1 is arranged on a needle seat 2, the dispensing needle head can be arranged on a dispensing injector for use, the diameter of the needle tube 1 near the needle seat end is large, the diameter of the needle near the needle tip end is small, the needle near the needle tip end is connected by a step formed by an excessive inclined surface, a side hole is arranged on the small-diameter part, and the distance between the edge of the needle point far away from the side hole and the step is L; for the medicine packaged in the ampoule, the needle tube part is consistent with the length of the common dispensing needle head, so that the liquid medicine in the ampoule can be conveniently sucked; for a large liquid container with a thick bottle stopper, the whole needle tube can be inserted into the bottle stopper to puncture the bottle stopper, and the liquid medicine can be injected into the large liquid container.

Claims (1)

1. The utility model provides a syringe needle of making up a prescription, comprises needle tubing, needle file, its characterized in that: the diameter of the needle tube near the needle base is large, the diameter of the needle tube near the needle tip is small, the needle tube near the needle tip is connected by a step formed by a transition inclined plane, a side hole is arranged on the small-diameter part, and the distance L between the edge of the needle tip far away from the side hole and the step is 4 +/-0.5 mm, or 5 +/-0.5 mm, or 6 +/-0.5 mm, or 7 +/-0.5 mm, or 8 +/-0.5 mm, or 9 +/-0.5 mm, or 10 +/-0.5 mm.
