一次性针灸针 Disposable acupuncture needle
技术领域 Technical field
本发明涉及一种针灸针。 背景技术 The invention relates to an acupuncture needle. Background technique
现有技术中, 管装针灸针由于进针时能减轻患者的痛感而受到大多数医生的欢 迎, 但也随之带来了污染及处理困难的问题。 由于所生产的针灸针是用插片将针柄 固定在套管中, 用时将插片取掉再将针灸针剌入患者穴位中, 然后去掉塑管, 对针 灸针进行捻针操作。这种使用过的针灸针会带有病菌, 易造成交叉感染, 给医务工 作者和废物处理的工作人员带来伤害。 发明内容 In the prior art, tube-mounted acupuncture needles are welcomed by most doctors because they can reduce the pain of patients when the needles are inserted, but they also bring problems of contamination and difficulty in handling. Since the produced acupuncture needles are fixed in the cannula with inserts, the inserts are removed and the acupuncture needles are inserted into the patient's acupoints, and then the plastic tube is removed, and the acupuncture needles are twisted. Such used acupuncture needles will carry germs, easily cause cross infection, and cause harm to medical workers and waste disposal workers. Summary of the Invention

如图 1、 图 2所示, 本发明包括针柄 4、 固定于针柄 4的下端部的针体 7、 套 在所述的针柄 4上的内套管 5、 套在所述的内套管 5上的外套管 8, 所述的针柄 4 与内套管 5固定连接, 针体 7的下部在内套管 5的下口部之外、 外套管 8的内腔之 中, 所述的内套管 5的外壁与外套管 8的内壁之间轴向滑动配合连接。 As shown in FIG. 1 and FIG. 2, the present invention includes a needle shank 4, a needle body 7 fixed to a lower end portion of the needle shank 4, an inner sleeve 5 sleeved on the needle shank 4, and a sleeve The outer cannula 8 on the cannula 5, the needle handle 4 is fixedly connected to the inner cannula 5, the lower part of the needle body 7 is outside the lower mouth of the inner cannula 5, and in the inner cavity of the outer cannula 8, The outer wall of the inner sleeve 5 and the inner wall of the outer sleeve 8 are connected in an axial sliding fit.
所述的外套管 8的上部内壁设有径向向内凸出的凸起环 2, 所述的内套管 5的 外壁与凸起环 2的内壁轴向滑动配合连接。所述的凸起环 2位于接近外套管 8上口 部的内壁上。 The upper inner wall of the outer sleeve 8 is provided with a convex ring 2 protruding radially inward, and the outer wall of the inner sleeve 5 and the inner wall of the convex ring 2 are axially slidably fitted and connected. The raised ring 2 is located on the inner wall near the upper mouth of the outer sleeve 8.
所述的内套管 5上设有径向向外延伸的限位凸块 3。所述的限位凸块 3位于内 套管 5的上端口部。 The inner sleeve 5 is provided with a limiting protrusion 3 extending radially outward. The limiting bump 3 is located at an upper port portion of the inner sleeve 5.
如图 1、 图 2所示, 所述的内套管 5的下端部设有向外张开的下卡片 6, 所述 的下卡片 6的上方的内套管 5上设有向外张开的上卡片 1 , 所述的上卡片 1位于凸 起环 2的下方。所述的下卡片 6有两片, 分别位于针体 7的前侧和后侧, 所述的上 卡片 1有两片, 分別位于针体 7的左侧和右侧。 As shown in FIG. 1 and FIG. 2, the lower end portion of the inner sleeve 5 is provided with a lower card 6 that is outwardly opened, and the inner sleeve 5 above the lower card 6 is provided with an outwardly opener. The upper card 1 is located below the raised ring 2. The lower card 6 has two pieces, which are respectively located on the front side and the rear side of the needle body 7, and the upper card 1 has two pieces, which are located on the left side and the right side of the needle body 7, respectively.
使用针灸针前, 本发明如图 1所示状态, 当把外套管 8的下口部压在穴位上时, 下压针柄 4, 可使内套管 5相对于外套管 8向下滑动至图 3所示的状态, 针灸结束 后, 上拉针柄 4, 使上卡片 1越过凸起环 2进入凸起环 2的上方, 如图 4所示, 而 下卡片 6被凸起环 2挡住, 内套管 5不能再向下进入外套管 8中。 工业应用性 Before using acupuncture needles, the present invention is shown in the state shown in FIG. 1. When the lower mouth portion of the outer sleeve 8 is pressed on the acupoint, pressing the needle handle 4 down can slide the inner sleeve 5 relative to the outer sleeve 8 to In the state shown in FIG. 3, after the acupuncture is completed, the needle handle 4 is pulled up so that the upper card 1 passes over the raised ring 2 and enters above the raised ring 2, as shown in FIG. 4, and the lower card 6 is blocked by the raised ring 2. The inner sleeve 5 can no longer enter the outer sleeve 8 downward. Industrial applicability
从以上具体实施例可以看出, 本发明具有以下优点: As can be seen from the above specific embodiments, the present invention has the following advantages:
1、 由于使用本发明时, 下压针柄, 可以使内套管在外套管内向下滑动, 针体 扎入穴位内, 使用完毕後, 上拉内套管, 可使针体又回到内套管中, 使针体不外露, 不会危及处理废物的工作人员。 1. When using the present invention, when the needle handle is pressed down, the inner cannula can slide down inside the outer cannula, and the needle body is inserted into the acupoint. After use, the inner cannula can be pulled up to return the needle body to the inside. In the cannula, the needle body is not exposed, and it will not endanger the workers who handle the waste.
2、 本发明使用完毕後, 由于下卡片被凸起环挡住, 内套管不能再向下进入外 套管中, 加热后外套管会自动把针体部分包住, 使得本发明起到一次性使用的作 用, 避免了重复使用而造成的交叉感染。
2. After using the present invention, since the lower card is blocked by the raised ring, the inner sleeve can no longer enter the outer sleeve downward. After heating, the outer sleeve will automatically cover the needle part, so that the present invention can be used once. Effect, to avoid cross-infection caused by repeated use.
