Description
Technical field
The present invention relates to the technical field of syringe construction, be specially the pre-encapsulated injector structure of mixed medicine.
Background technology
To extract solvent (water for injection etc.) out with syringe first in traditional injector operations process, again syringe needle is penetrated solute bottle (injectable powder or aqueous injection), then release solvent and mix with solute and dissolve, extract again at last admixing medical solutions out and could inject or to dosing in the infusion bottle human body in the syringe.This operational approach not only program is complicated, and nurse's amount of labour is large, and medicinal liquid will through shifting several times, easily pollute.The most important thing is easily to occur causing the generation of malpractice because of wrong medicine, until jeopardize patient's life security.
Existing pre-encapsulated injector, they all are to be potted in the syringe after medicine is prepared.Because this pre-encapsulated injector is produced patient's use there is the regular hour, because mix in syringe for a long time after solvent and solute mix and cause solvent and solvent hybrid reaction or solvent and solute hybrid reaction or solute and solute hybrid reaction or solute and solvent qualitative change, this also just reduces the side effect that drug effect also has medicine simultaneously.
Existing mixed medicine pre-encapsulated injector, their structure is very complicated, solute and solvent fill trouble, mixed drug anesthesia is tired of before the injection, production cost is very high, is difficult to realize mass production.
Summary of the invention
For the problems referred to above, the invention provides the pre-encapsulated injector structure of mixed medicine, it is simple in structure, and solute and solvent fill are simple, and production cost is low, easily realizes mass production.
The pre-encapsulated injector structure of mixed medicine, its technical scheme is such: it comprises the solute syringe, the solvent syringe, described solute syringe specifically comprises core bar, overcoat, piston, stopper, the inner chamber of described overcoat is equipped with described core bar, the front end sleeve of described core bar is equipped with described piston, the outer rim anchor ring of described piston is close to the inwall of described overcoat, form the molten chamber of solute between the inwall of the lower surface of described piston and the described overcoat of its underpart, the front end exit of described overcoat is set with described stopper, it is characterized in that: the central upper of described piston is provided with the piston pin hole, the bottom is provided with closure seam, described piston pin hole is communicated with described closure seam, described closure seam is communicated with the molten chamber of described solute, the top of the core bar of described solute syringe is provided with the internal ring draw-in groove, the lower end cutting ferrule of spiral base is in described internal ring draw-in groove, the upper cap of the described spiral base under the preservation state is equipped with block, the central upper portion of described spiral base is provided with the taper hole chamber, the below in described taper hole chamber is base, the center of described base is provided with pin hole, described taper hole chamber is communicated with described pin hole, pin runs through described core bar, its two ends are communicated with respectively described pin hole, the piston pin hole, described block breaks away from described spiral base during mixing, the front end conehead of described solvent syringe is plugged in the taper hole intracavity of described spiral base, and the liquid outlet of described solvent syringe is communicated with described taper hole chamber.
It is further characterized in that: described solvent syringe specifically comprises core bar, overcoat, piston, stopper, the inner chamber of described overcoat is equipped with described core bar, the front end sleeve of described core bar is equipped with described piston, the outer rim anchor ring of described piston is close to the inwall of described overcoat, the front-end-cone headgear of described overcoat is equipped with described stopper, forms the molten chamber of solvent between the inwall of the lower surface of described piston and the described overcoat of its underpart;
The outer end, top of described spiral base is provided with external screw thread, and the installation anchor ring inwall of the front end conehead of described solvent syringe is provided with female thread, the installation anchor ring of the described solvent syringe described spiral base that is threaded.
After using structure of the present invention, with the solute fill in the molten intracavity of the solute of solute syringe, with the solvent fill in the solvent syringe, packaging sterilizing is waited to go on the market, when needing to use, pull out block, the front end conehead of solvent syringe is inserted the taper hole chamber of spiral base, so that the liquid outlet of solvent syringe is communicated with the taper hole chamber, promote the solvent syringe, solvent passes piston through pin, because solvent has certain pressure, strut the closure seam of piston, the molten chamber of solute solvent constantly increases, be enclosed within outward under the molten chamber molten intracavity of the solute section pressure for enlarging volume relatively core bar move forward, inject and pull out the solvent syringe after finishing, cover block, vibrations solute syringe makes solvent and solute at mixed medicine pre-encapsulated injector mix homogeneously, spins off stopper, the drain gas in the molten chamber of solute of promotion core bar, the injector is injected at once, throw away after the injection, it is simple in structure, and solute and solvent fill are simple at once, production cost is low, easily realizes mass production.
