Medical injection device

A medical injection device comprising:

• a container including an internal storage space formed therein to contain and store an injection solution, and an injection solution outlet port formed at a lower portion thereof;
• an injection solution filter connected to the injection solution outlet port of the container to filter out the injection solution flown through the injection solution outlet port;
• a guide tube connected to a lower portion of the injection solution filter to provide a flow passage for injecting the injection solution filtered through and discharged out of the injection solution filter;
• an injection solution level controller which is configured to control an opening degree for allowing an air to be flown into or discharged from the container, and connects a first level control port formed at an upper portion of the container and a second level control port formed at an upper portion of the injection solution filter in communication with each other;
• and
• an agitation means which is provided in the container, and when vibration occurs in the container, is configured to swing to agitate the injection solution in the container,
• wherein the agitation means comprises:
• a first agitator suspended and fixed to an upper side of the container so as to move without hindrance and
• a second agitator connected to a lower end of the first agitator so as to move without hindrance,
• wherein the first agitator is formed in such a way that a lower portion of the first agitator is heavier than an upper portion of the first agitator, and the second agitator is formed in such a way that an upper portion of the second agitator is heavier than a lower portion of the second agitator.
