Description

Automatic injection powder mixing syringe
Technical field
The present invention relates to a kind of injector for medical purpose, particularly relate to a kind of in clinical use the syringe of injectable powder and solvent automatic medicine-mixing.
Technical background
The conventional injector medication is made generally in water preparation or powder.Though aqueous injection is easy to use, deposit, transport inconvenience and short-life disadvantage.Though and its drug effect height of injectable powder, the good stability that use clinically at present, but its packing cost height, be solute with in solvent is packaged in different medicine bottles respectively, and must pass through following five programs when using: (1) is got a syringe and is punctured solvent bottle plug (2) (3) in the solvent inhalation syringe are punctured the solute bottle plug, solvent is injected in the solute bottle, and mixing (4) is given patient infusion (5) in the medicinal liquid inhalation syringe of mixing in the solute bottle or is given the infusion bottle dosing.Therefore have following shortcoming:
1, operation sequence complexity has increased nurse's labor intensity.
2, the situation of mismatch medicine takes place easily.
3, in many steps of making up a prescription, cause the pollution of outside air to medicine.
4, chemotherapy and toxic medicament outer the rushing down in the process of making up a prescription can be caused damage to medical personnel's health.
5, it is residual to have medicinal liquid in the solvent bottle, causes waste.
Present powder needle injection is because its structural advantage more and more is subjected to medical personnel and patient's welcome.The powder needle injection generally is made up of solute bottle and syringe or solvent bottle.But existing powder needle injection solute bottle adopts adhesive tape to be connected with the connected mode of solvent bottle, and it is loaded down with trivial details to mix the medicine process operation, can not finish the medicine process of mixing automatically.
Summary of the invention
The purpose of this invention is to provide the automatic injection powder mixing syringe that a kind of simple to operate, automatic medicine-mixing and mixed medicine process are not subjected to outside contamination.
For achieving the above object, the technical solution used in the present invention is: a kind of automatic injection powder mixing syringe, comprise solvent bottle, solute bottle and pin medicated cap, also comprise solute bottle overcoat, solvent bottle overcoat, rotary sleeve, one grade of pushing sleeve and second gear pushing sleeve, described solute bottle places in the solute bottle overcoat, described solvent bottle, one grade of pushing sleeve and second gear pushing sleeve place in the solvent bottle overcoat, and described rotary sleeve is enclosed within solvent bottle overcoat outside, and described solute bottle overcoat is connected up and down with solvent bottle overcoat.
Related content in the technique scheme is explained as follows:
1, is respectively equipped with the location stuck point of projection on the body of described one grade of pushing sleeve and second gear pushing sleeve.
2, described solvent bottle overcoat has chute, is provided with solvent bottle overcoat locating groove in the bottom of chute.
3, described rotary sleeve inwall is provided with one grade of pushing sleeve stopper slot, second gear pushing sleeve stopper slot and rotary sleeve limited bayonet.The arc that the moving towards of described one grade of pushing sleeve stopper slot (22) and second gear pushing sleeve stopper slot (23) adopted spiral type or had angle.The scope of the anglec of rotation be 1 spend to 90 the degree.No matter which kind of trend one grade of pushing sleeve stopper slot (22) and second gear pushing sleeve stopper slot (23) adopt, as long as one grade of pushing sleeve 5 and second gear pushing sleeve 6 are moved along one grade of pushing sleeve stopper slot 22 and second gear pushing sleeve stopper slot 23, reach syringe needle and at first puncture the solute bottle plug, and then the purpose that punctures the solvent bottle plug gets final product.The rotary sleeve limited bayonet matches with solvent bottle overcoat locating groove, rotary sleeve can be rotated and can not move up and down.
4, described location stuck point places the chute of solvent bottle overcoat, in chute, can move up and down, and the location stuck point protrudes in the outer surface of solvent bottle overcoat, be stuck in one grade of pushing sleeve stopper slot and the second gear pushing sleeve stopper slot orbiting motion that is limited along one grade of pushing sleeve stopper slot and second gear pushing sleeve stopper slot.
6, described pin medicated cap top is provided with bayonet socket, and double-sided needle is equipped with in the centre.When rotary sleeve rotated, one grade of pushing sleeve at first moved, and drove the punctures solute bottle plug on the pin medicated cap, and the lost motion of second gear pushing sleeve drives the motion of solvent bottle and then makes punctures solvent bottle plug.
7, described solute bottle overcoat bottom is provided with bayonet socket.Solute bottle overcoat bayonet socket matches with pin medicated cap bayonet socket.When rotary sleeve rotates, in the pin medicated cap bayonet socket precession solute bottle overcoat bayonet socket, make the plug of punctures solute bottleneck.
8, be filled with gas in the described solvent bottle.When the plug of the plug of punctures solvent bottleneck and solute bottleneck, under the effect of pressure, solvent is ejected in the solute bottle automatically by pin hole.
Because the technique scheme utilization, the present invention compared with prior art has following advantage and effect:
1, easy to operate, use very simply, only need rotate, just can realize automatic medicine-mixing, rotate again, just can clinically use, alleviated nurse's labor intensity greatly.
2, complete closed in mixed medicine process, medicine can not be subjected to the pollution of outside air, has prevented from simultaneously to rush down harm to medical personnel as chemotherapy, the toxic medicament China and foreign countries of making up a prescription yet.
3, because be filled with pressure in the solvent bottle, solvent all sprays to the solute bottle under pressure, and it is residual not have medicinal liquid, avoids causing unnecessary waste.
4, can not reuse after the present invention's injection finishes, reach complete disposable purpose, avoid reusing the blood infection that syringe causes.
