Abstract: The present invention relates to a component separator capable of guaranteeing the purity of a subject component such as isolated blood or stem cells while simplifying a process compared with a conventional technique, and preventing air contamination during a component separation process, the component separator comprising: a hollow main body having a communication pipe, through which a body fluid communicates, formed at one end portion, and a main body female screw part disposed at the other end portion; a plunger for varying a main body space while moving forward and backward inside the main body; and an operation member having a pressing tube having a pressing male screw part capable of being screwed with the main body female screw part, and a plunger coupling tube having a tube screw screwed with a plunger screw part at the lower part of the plunger by coming into contact with or retracting from the inside of the pressing tube.

Abstract: The present invention relates to a medical injection device for preventing a target substance contained in an injection solution from being lost when the target substance is not settled or floated, and for evenly agitating the injection solution to be safely injected. A medical injection device according to the present invention includes a container having an agitation means and a vibration sensing ball, an injection solution filter, an injection solution level controller, a bellows connector, and a guide tube.

Abstract: The present invention provides a medical injection device having the following effects: the container containing an injection solution and an agitation means provided in the container are vibrated to agitate the injection solution, so as to allow a target substance contained in the injection solution to be injected at a uniform concentration with being sufficiently agitated, and thereby a fatal medical accident that may be caused by an nonuniform concentration of the target substance may be prevented; the container and the filter and/or an expansion tube are connected with each other through an injection solution level controller, such that a level and an injection rate of the injection solution filled therein may be more freely controlled; and in particular, in order to allow the injection solution to be subjected to a sediment filtration process inside the filter, the injection solution is injected while being filled in the filter at a preset level or more, thereby the target substance such as the stem cell

Abstract: Disclosed is a blood ingredient separator capable of assuring purity of such as separated blood components or stem cells as well as preventing contamination by ambient air during the process of separating components, while simplifying the processes compared to the related art. The ingredient separator includes: a hollow body which includes a flow tube formed at one end portion thereof for communicating body fluids, and a stopper disposed at the other end portion thereof; and a plunger which is movably installed back and forth in the body to vary a space between the flow tube and a top of the plunger thereof; wherein the plunger has a collection portion formed on the top thereof, and a backward movement of the plunger is limited by the stopper.
