Abstract: Proposed is a reversible electroporation system including a middle connector combined with a cradle, the system using an electroporation needle including an internal drug channel and an electrode pattern formed on the external surface thereof, so as to allow the application of electric pulses and the formation of electric fields at a lesion site of a patient and enable a corresponding drug to be delivered, thereby enabling an accurate and stable procedure for a diseased part of the body of the patient, wherein the middle connector has a seating part so as to be stably fixed on the body without slipping, and has a first mesh-type fixing part placed therein so that, when the needle is inserted into a certain part of the body, an electroporator can be inserted at an accurate position together with the mesh-type fixing part, and when more stable fixation is required according to the convenience and need of an operator, an electroporator cradle including a second mesh-type fixing part is further provided so that a

Abstract: A development cartridge is provided. The development cartridge includes a toner container, having a first air vent and a second air vent, to accommodate a toner, a developing portion to receive the toner from the toner container and having a developing roller installed therein, a toner refilling portion, connected to an end of the toner container in a longitudinal direction, to provide the toner container with a passage for refilling the toner, a filter installed in the first air vent to reduce leakage of the toner, and a pressure releasing member to communicate with the toner container via the second air vent and being transformable in a contracted state and an expanded state to expand a volume of the toner container, wherein the first air vent is formed at a position farther from the toner refilling portion than the second air vent.

Abstract: A toner cartridge includes a container having an opening, a flexible bag in which toner is received, a sealing portion configured to seal the flexible bag, and an extension extending from an edge of the sealing portion, the flexible bag being accommodated in the container so that the sealing portion faces the opening, a rotatable member rotatably provided on the container, a movable member connected to the extension and being movable from a first position close to the opening to a second position far from the opening in a longitudinal direction of the container, a rope having a first end portion connected to the rotatable member and a second end portion connected to the movable member, and a bias member configured to elastically bias the rotatable member to rotate in a direction in which the rope is switched from an unwound state to a wound state.
