The present invention relates to a filter and, more specifically, to a filter unit which is formed to filter an internal impurity inside a container of injection solution such as ample during a suction or an injection of the injection solution. The filter unit according to the present invention comprises: a hollow injection body part, having a first filter and a second filter which are different from each other in size of air gaps mounted on inside; and a hollow hub, forcibly coupled to one side of the injection body part. The injection body part includes a filter supporting unit, having a radial shape, and each supporting piece thereof extends radially with respect to a center. Therefore, the filter unit for a medical syringe according to the present invention prevents deformation of the filter which can occur during a manufacturing process or when using the same, and removes various foreign substances such as a bubble and fine particle as well as broken pieces of glass. Further, the filter unit for a medical syringe according to the present invention has an advantage of being used together with a multi-directional and functional stopcock as well as a general syringe. |
