Injection device and injection solution transferring system

A method for dispensing solution from a solution dispensing device, the solution dispensing device having a rotatable plunger, a solution receptacle, a housing, a first stop member, and a second stop member, the method comprising:

• slidably inserting the rotatable plunger into a first end of the solution receptacle, wherein a second end of the solution receptacle is configured to dispense the solution contained in the solution receptacle;
• while the rotatable plunger is in a first orientation, slidably displacing the rotatable plunger along a first axis until the rotatable plunger is in a first position relative to the solution receptacle, wherein:
• the housing is configured to releasably connect to the solution receptacle, wherein the housing includes a plunger through-hole that is configured to slidably receive the rotatable plunger and to allow the solution receptacle to slidably receive the rotatable plunger;
• the first stop member prevents the rotatable plunger from being slidably displaced to a second position relative to the solution receptacle that is closer to the second end of the solution receptacle than the first position while the rotatable plunger is at the first position and in the first orientation, wherein:
• the first stop member projects from a top surface of the housing in a proximal direction away from the second end and along the first axis, wherein the top surface of the housing faces away from the second end of the solution receptacle, and
• the first stop member has a first height relative to the top surface of the housing;
• and
• the second stop member prevents the rotatable plunger from rotating in a first direction about the first axis while the rotatable plunger is at the first position and in the first orientation, wherein:
• the second stop member projects from the top surface of the housing in the proximal direction away from the second end and along the first axis, and
• the second stop member has a second height relative to the top surface of the housing that is greater than the first height;
• rotating the rotatable plunger in a second direction about the first axis until the rotatable plunger is in a second orientation at the first position;
• and
• while the rotatable plunger is in the second orientation, slidably displacing the rotatable plunger along the first axis until the rotatable plunger is in the second position relative to the solution receptacle, wherein slidably displacing the rotatable plunger from the first position to the second position in a distal direction dispenses a quantity of the solution contained in the solution receptacle.
