Description
Technical field
The present invention relates to injector for medical purpose technical field, particularly single use Syringes with reservoir.
Background technology
First solvent (i.e. water for injection) is extracted out with syringe in traditional injection manipulation, again syringe needle is penetrated solute bottle (injectable powder or aqueous injection), then release solvent to carry out mixing dissolving with solute, finally extract out again in admixing medical solutions to syringe and could to inject human body or to dosing in infusion bottle.This operational approach program is complicated, and nurse's amount of labour is large, and medicinal liquid through shifting several times, easily will pollute.
At present, there is the structure in same syringe by solvent and solute common storage, as Chinese patent 2008200292616 disclosed " injectable powder aseptic chemical mixing pre-encapsulated injector ", Chinese patent 2008200301441 disclosed " two rooms cartridge bottle powder injection pre-filling syringe ", Chinese patent 2012202806593 disclosed " pigment unification fast syringe " etc., its structure is all powder storage chamber and water preparation storage chamber are separated by a piston, during use, or realize pigment mixing by acupuncture this piston saturating, or make to occur gap between piston with syringe by promoting piston thus realize mixing of pigment.But all there is the piston separating pigment in existing structure can only to syringe needle direction unidirectional motion, when carrying out also very easily causing the piston separating pigment to be moved by trend syringe needle direction in the process that water preparation pushes to powder chamber, and then make the volume of the cavity holding powder become the final maximum splendid attire volume holding pigment intermixture, piston just causes the further reduction of this volume to the movement in syringe needle direction, thus usually there is water preparation and can not inject the problem that powder holds chamber completely in this type of syringe, or because this appearance cavity pressure is excessive in mixed process, the phenomenon that medicinal liquid is discharged from syringe needle, normal injection demand can not be met.Meanwhile, existing pigment store that the assembly of syringe is many, complex structure altogether, reduce further stability and reliability that syringe uses, and processing, packaging technology are complicated, and cost is high, governs applying of this type of syringe.
