具体实施方式detailed description
下面结合附图和实施例对本实用新型进一步说明，实施例的内容不作为对本实用新型的保护范围的限制。The utility model will be further described below in conjunction with the accompanying drawings and examples, and the contents of the examples are not intended to limit the scope of protection of the utility model.
图1示出了本实用新型的防复用一次性注射器的结构示意图。如图1所示，与现有的普通注射器相类似，本实用新型的防复用一次性注射器包括空筒1。优选地，所述空筒1上设置有刻度，以便于观察注射量。所述空筒1的前端设置有乳头2。所述乳头2用于与针头相连。Fig. 1 shows a schematic structural view of the anti-reuse disposable syringe of the present invention. As shown in FIG. 1 , similar to the existing common syringe, the anti-reuse disposable syringe of the present invention includes an empty barrel 1 . Preferably, a scale is provided on the empty cylinder 1 for easy observation of the injection volume. A teat 2 is provided at the front end of the empty barrel 1 . The nipple 2 is used to connect with a needle.
与现有的注射器不同，在本实用新型中，所述空筒1内靠近所述乳头2的一端设置有环形卡槽3。优选地，所述环形卡槽3内形成圆台形孔且所述圆台形孔的靠近所述乳头2的一端的孔径小于另一端的孔径。这样，便于后述的橡胶活塞4从所述空筒1的后端推过所述环形卡槽3，但是不易再从所述环形卡槽3中抽出。Different from the existing syringes, in the present invention, an annular locking groove 3 is provided at the end of the empty barrel 1 close to the nipple 2 . Preferably, a frustum-shaped hole is formed in the annular locking groove 3 and the diameter of one end of the frustum-shaped hole close to the nipple 2 is smaller than the diameter of the other end. In this way, it is convenient for the rubber piston 4 to be described later to push through the annular locking groove 3 from the rear end of the hollow cylinder 1 , but it is difficult to pull out from the annular locking groove 3 again.
所述空筒1内还设置有橡胶活塞4。所述橡胶活塞4与活塞轴5的一端相连。所述活塞轴5的另一端与活塞柄6相连。这样，手动推动所述活塞柄6，即可推动所述橡胶活塞4向前移动，从而推出药液。A rubber piston 4 is also arranged in the hollow cylinder 1 . The rubber piston 4 is connected to one end of the piston shaft 5 . The other end of the piston shaft 5 is connected with the piston handle 6 . In this way, by manually pushing the piston handle 6, the rubber piston 4 can be pushed forward to push out the medicinal liquid.
在本实用新型中，如图2所示，所述活塞轴5的与所述橡胶活塞4相连的一端设置有球形连接头8。所述橡胶活塞4中设置有容纳所述球形连接头8的球形接纳孔7。这种连接结构使得当向前推动所述橡胶活塞4时，所述橡胶活塞4与所述活塞轴5之间不易脱落；但是，当向后抽出所述橡胶活塞4时，由于所述橡胶活塞4的材料使得所述球形接纳孔7易于变形，从而使得所述橡胶活塞4与所述活塞轴5之间易于脱落。In the present invention, as shown in FIG. 2 , one end of the piston shaft 5 connected to the rubber piston 4 is provided with a spherical joint 8 . The rubber piston 4 is provided with a spherical receiving hole 7 for accommodating the spherical joint 8 . This connection structure makes it difficult to fall off between the rubber piston 4 and the piston shaft 5 when the rubber piston 4 is pushed forward; The material of 4 makes the spherical receiving hole 7 easy to deform, so that the rubber piston 4 and the piston shaft 5 are easy to fall off.
在使用本实用新型的防复用一次性注射器时，用此注射器先抽吸药物，注射时通过所述活塞柄6推动所述橡胶活塞4向前将药物通过针头注射到人体中。在药物推注完毕时，所述橡胶活塞4进入所述环形卡槽3内。拔针后，向后抽拉所述活塞柄6，由于所述橡胶活塞4卡在所述环形卡槽3内难以拔出，并且由于所述球形接纳孔7的变形，导致所述活塞轴5与所述橡胶活塞4分离。这样，所述橡胶活塞4被留在所述空筒1内，因此杜绝了一次性注射器复用的可能性。When using the anti-reuse disposable syringe of the present utility model, use the syringe to suck the medicine first, and push the rubber piston 4 forward through the piston handle 6 to inject the medicine into the human body through the needle during injection. When the injection of the drug is completed, the rubber piston 4 enters the annular groove 3 . After pulling out the needle, pull the piston handle 6 backwards, because the rubber piston 4 is stuck in the annular groove 3 and it is difficult to pull out, and due to the deformation of the spherical receiving hole 7, the piston shaft 5 Separated from the rubber piston 4. In this way, the rubber piston 4 is left in the empty barrel 1, thus eliminating the possibility of reusing the disposable syringe.
本实用新型的防复用一次性注射器在使用过后即丧失使用价值，间接地减少了一次性注射器的回收，杜绝了一次性注射器的复用。同时，其结构简单、操控方便，且价格低廉，便于推广应用。再者，其不带利器，不会误伤医护人员等。The anti-reuse disposable syringe of the utility model loses its use value after use, which indirectly reduces the recovery of the disposable syringe and prevents the reuse of the disposable syringe. At the same time, the utility model has the advantages of simple structure, convenient operation and low price, and is convenient for popularization and application. Furthermore, it does not carry a sharp weapon, so it will not accidentally injure medical staff.
本实用新型的上述实施例仅仅是为清楚地说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无法对所有的实施方式予以穷举。凡是属于本实用新型的技术方案所引伸出的显而易见的变化或变动仍处于本实用新型的保护范围之列。The above-mentioned embodiments of the present utility model are only examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. All the implementation manners cannot be exhaustively listed here. All obvious changes or variations derived from the technical solutions of the utility model are still within the scope of protection of the utility model.
