Abstract
The utility model discloses a double chamber clamping-type bottle powder-injection prefilling injector which comprises a push rod. The push rod extends into one end of an injection main body, the other end of the injection main body is provided with a needle, the inner part of the injection main body is provided with a main piston and a middle piston, and the main piston is contacted with the push rod. Furthermore, an aqua cavity is arranged between the main piston and the middle piston, a powdered drug cavity is arranged between the middle piston and the needle, the powdered drug cavity is internally provided with a groove along the inner coaxial wall, and the length of the groove is longer than that of the middle piston. The utility model has great convenient operation, the liquid medicine is completely isolated from the outside so as to completely avoid the secondary pollution of drugs and the pollution of the drugs for the environment, thereby the utility model accords with the clinic using standard of the drugs.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of pair of chamber cassette bottle injectable powder prefilled syringe.
Background technology
When the nurse gives patient infusion powder injection formulation (example hydrochloric acid spectinomycin, azithromycin) usually; penetrate solute (powder) medicine bottle again after extracting solvent (water agent for injecting) out with syringe earlier; releasing diluent dissolves powder; and then inhalation syringe could be injected; whole process is more with thing; operation sequence complexity, syringe are polluted and cross infection easily, and also occur adorning wrong medicine and the malpractice that causes through regular meeting.This operation sequence that is determined by syringe and maneuver are extremely strict to nurse's requirement, and it is a bit careless to occur, and nurse's mental pressure is too big.
The fill respectively of water preparation and powder is in two bottles in the existing clip type bottled syringe, in clinical use, must transfer to water preparation in the powder bottle, the transfer of medicine has increased the secondary pollution chance of medicine, and trivial operations, occurs the human error easily.
Summary of the invention
The purpose of this utility model provides a kind of pair of chamber cassette bottle injectable powder prefilled syringe, solved exist in the prior art with water preparation and powder respectively fill in different bottles, increased the secondary pollution problem of medicine.
The technical scheme that this utility model adopted is, a kind of pair of chamber cassette bottle injectable powder prefilled syringe, comprise push rod, push rod puts in an end of injection body, is provided with syringe needle at the other end of injection body, be provided with main piston and intermediate piston in the inside of injection body, main piston contacts with push rod, is the water preparation chamber between main piston and the intermediate piston, is the powder chamber between intermediate piston and the syringe needle, inwall is provided with groove vertically in the powder chamber, and the length of groove is greater than the length of intermediate piston.
The beneficial effects of the utility model are, two kinds of medicines do not contact with the external world, have avoided the pollution to environment of the secondary pollution of medicine itself and medicine fully, the clinical operating specification that meets medicine, and simple in structure, easy to operate, stopped the human error, the cost of product obviously reduces.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a work sketch map of the present utility model.
Among the figure, 1. push rod, 2. main body, 3. handle, 4. main piston, 5. water preparation chamber, 6. intermediate piston, 7. groove, 8. powder chamber, 9. syringe needle, 10. pinhead sleeve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is elaborated.
Fig. 1 is a structural representation of the present utility model.Comprise injection body 2, be provided with handle 3 at the excircle of injection body 2, be provided with push rod 1 at an end of injection body 2, be provided with syringe needle 9 at the other end of injection body 2, syringe needle 9 is outside equipped with pinhead sleeve 10.Be provided with main piston 4 and intermediate piston 6 in the inside of injection body 2, main piston 4 contacts with push rod 1, between main piston 4 and the intermediate piston 6 water preparation chamber 5 is set, fill water agent for injecting in the water preparation chamber 5, be powder chamber 8 between intermediate piston 6 and the syringe needle 9, fill injectable powder in the powder chamber 8, be provided with two grooves 7 vertically on 8 inwalls of powder chamber, the length of groove 7 is greater than the length of intermediate piston 6.
Fig. 2 is a work sketch map of the present utility model.During use, compressing push rod 1 promotes piston 4 and moves to the syringe needle direction, piston 4 is oppressed intermediate piston 6 simultaneously by the water preparation in the water preparation chamber 5 and is moved together, when middle piston 6 moves to groove 7 middle parts, water preparation chamber 5 and powder chamber 8 are communicated with by groove 7, piston 4 was pressed into powder chamber 8 with water preparation and mixed with powder this moment, intermediate piston does not move for 6 this moments, after all entering powder chamber 8 in the water preparation in water preparation chamber 5, shake injection body 2 powder is dissolved fully by water preparation, promote piston 4 at last and move together with intermediate piston 6 and finish injection.
Syringe holder water preparation of the present utility model and powder are sub-packed in two cavitys of same cassette bottle, and cavity cuts off with the piston that can slide.Again water preparation is pressed in the powder cavity when using clinically, waits to dissolve the back and continue to promote piston enforcement injection.Injector operations of the present utility model is very easy, and medicinal liquid does not contact with the external world fully, has avoided the pollution to environment of the secondary pollution of medicine itself and medicine fully, meets the clinical operating specification of medicine.
