摘要:
Provided are a filtering needle, which has a rotationally cuttable and removable intake tube coupled thereto, and a filtering syringe using same. The present invention relates to a filtering needle, which overcomes the shortcoming of a conventional filtering syringe in which while the conventional filtering syringe performs a filtering intake and the discharge of an injectable solution using one needle, glass fragments, which do not flow deeply into the inner channel of a filter but remain between the needle and the filter, are introduced into a human body via the needle during an injection, the filtering needle being characterized in that while an intake part (20) provided with an intake tube, which is slightly larger than the needle, and capable of being spirally cut is placed over a needle part (10) and then rotationally removed therefrom, a connecting tube (24) inside the intake part and embedded in an inlet (16) comes out and simultaneously interlocks with a rotary plate plug (14) of the needle part, thereby closing the inlet (16) connected to the filter (15) and opening an outlet (17) connected to the needle (11). Owing to the above simple and sophisticated operation of soft components, the needle remains in the state of a bidirectionally open outflow tube, not a unidirectional conduit, even after completion of an intake. Accordingly, the status of blood detection can be confirmed by inserting the filtering needle into a human body and then slightly drawing in, as in the case of a general needle, and glass fragments filtered by the filter (15) are completely separated from the needle at this moment; thus, the filtering needle has the outstanding effect of preventing a filtered substance from being reinjected into the human body in comparison with conventional filtering syringes.
