An injection device () comprises an injection solution receptacle () and a plunger () at feast a portion of which is slidably received in the injection solution receptacle (), wherein the plunger () is displaceable relative to the injection solution receptacle () in a distal direction in order to expel an injection solution contained in the injection solution receptacle () from the injection solution receptacle (). A first plunger stop mechanism () is adapted to stop a displacement of the plunger () relative to the injection solution receptacle () in the distal direction at a first dosing position (P). A second plunger stop mechanism () is adapted to stop a displacement of the plunger () relative to the injection solution receptacle () from the first: dosing position (P) in the distal direction at a second dosing position (P), wherein the first and the second dosing position (P) of the plunger () are selected in such a manner that the plunger (), upon being displaced relative to the injection solution receptacle () between the first and the second dosing position (P) is adapted to expel a desired dose of the injection solution contained in the injection solution receptacle () from the injection solution receptacle ().

Injection device and injection solution transferring system

A pump is connected between penile cylinder(s) and a reservoir of a prosthesis. A squeezing pressure applied to the penile cylinder moves a first liquid volume out of the cylinder and into a first chamber of the pump, which displaces a piston inside of the pump. Displacement of the piston creates a vacuum space (a second chamber) between the piston and the housing of the pump, and a second liquid volume is drawn out of the reservoir and into the vacuum space. A return spring pushes the piston back to its starting position, which pushes both the first liquid volume and the second liquid volume out of the pump and into the penile cylinders.

An injection device () comprises an injection solution receptacle () and a plunger () at least a portion of which is slidably received in the injection solution receptacle (), wherein the plunger () is displaceable relative to the injection solution receptacle () in a distal direction in order to expel an injection solution contained in the injection solution receptacle () from the injection solution receptacle (). A first plunger stop mechanism () is adapted to stop a displacement of the plunger () relative to the injection solution receptacle () in the distal direction at a first dosing position (P). A second plunger stop mechanism () is adapted to stop a displacement of the plunger () relative to the injection solution receptacle () from the first dosing position (P) in the distal direction at a second dosing position (P), wherein the first and the second dosing position (P) of the plunger () are selected in such a manner that the plunger (), upon being displaced relative to the injection solution receptacle () between the first and the second dosing position (P) is adapted to expel a desired dose of the injection solution contained in the injection solution receptacle () from the injection solution receptacle ().
