Detailed Description
The present invention is not limited by the following examples, and specific embodiments may be determined according to the technical solutions and practical situations of the present invention.
As shown in fig. 3-6, the universal dispensing needle according to the present invention includes a needle tube 5, a limiting structure 6 is fixed at a position on the needle tube 5 near the needle tip, the limiting structure 6 is one of a limiting indentation, a limiting welding point or a limiting kit, the limiting indentation may be a circle of indentation on the needle tube 5 in the circumferential direction of the needle tube, and the limiting kit may be a cylindrical hollow rubber ring, which is sleeved at the limiting position of the needle tube 5 to achieve a limiting effect. The distance L1 between the limiting structure 6 and the needle tip of the needle tube 5 is 15 +/-5 mm, so that the needle tube 5 in the penicillin bottle is proper in length and not too long when the penicillin bottle is used for sucking or injecting liquid medicine; when the needle tube sucks the liquid medicine in the ampoule bottle, the ampoule bottle is slender, the inner diameter of the bottle opening is far larger than the outer diameter of the limiting structure, the limiting structure does not block the length of the needle tube entering the ampoule bottle any more, the needle tube can completely enter the ampoule bottle, and the liquid medicine in the ampoule bottle is sucked cleanly. Because limit structure 6 is one of spacing indentation, spacing solder joint or spacing external member, and limit structure volume is less, and is with low costs, consequently increased limit structure's general dispensing needle and original needs be equipped with xiLin bottle and ampoule dedicated dispensing needle and compare, the cost is reduced.
The needle tip of the needle tube 5 is one of the following two types:
