Abstract

A powder injector comprises an injector with a needle, an injector cylinder and a reagent bottle which is divided into two chambers, and a sealing device is arranged on the bottle mouth and the chambers. The papilla part of the injector cylinder is inserted into the jamming hole of the sealing device of the bottle mouth, and the needle of the injector cylinder is arranged in the outer chamber of the reagent bottle, and a safety device preventing the relative movement of the injector cylinder and the double ventricular bottle is arranged therebetween. The adoption of double ventricular bottle can make the powder injector have the advantages of simple structure and low cost, and solves the problems of the present technology of many components and high cost, and is good for popularization. In application, once the safety device between the injector cylinder and the double ventricular bottle is broken, the injector cylinder can be pushed to insert the needle into the inner chamber of the double ventricular bottle, then the pushing rod of the injector cylinder is pushed to mix the liquid formulation and the powder, thus to complete injection.

Description

The powder needle injection
Technical background
Present powder needle injection generally also is made up of powder bottle and syringe, but powder bottle is single chamber structure, adopted this structure after, member between powder bottle and the syringe is made complicated, cost is higher, is unfavorable for extensive use.
Technology contents
The powder needle injection comprises syringe and ampoule that syringe needle is installed, it is characterized in that ampoule is divided into two chambers, reaches bottleneck between chamber sealing device is installed; The nipple portion of syringe is inserted in the sealing device hole clipping place of bottleneck, and the syringe needle of syringe is installed in the outer chamber of ampoule; The safety that prevent the two relative motion are installed between syringe and the double chamber bottle.Adopt the structure of double chamber bottle, make the simple structure of whole powder needle injection, cost low, the deficiency that the member that has solved prior art is many, cost is high helps applying.When syringe uses,, just can advance syringe, make the inner cavity chamber of syringe needle insertion double chamber bottle, advance the push rod of syringe again, liquor be mixed with powder, thereby can inject as long as destroyed safety between syringe and the double chamber bottle.
Above-mentioned powder needle injection is characterized in that sealing device between two chambers of double chamber bottle is intermediate thin, thick common ampoule plug all around.This structure is the most frequently used a kind of medical hermetically-sealed construction.
Above-mentioned powder needle injection is characterized in that being equipped with between needle cylindrical unit and the injecting propeller safety that prevent the two relative motion.Mainly be when preventing that this product from not using, injecting propeller has destroyed sealing device because reasons such as vibrations enter in the syringe, makes product unavailable.
Above-mentioned powder needle injection is characterized in that safety between syringe and the double chamber bottle are to constitute like this: a collar is installed between syringe and double chamber bottle, the collar two ends respectively with double chamber bottle and syringe jacking.Withstand double chamber bottle and syringe with collar, make the two that relative motion can not take place, thereby protected using of product.
Above-mentioned powder needle injection is characterized in that the vertical commissure of described collar is linked to each other by adhesive tape.Adopt this structure, can take adhesive tape simply apart, can use.
Above-mentioned powder needle injection is characterized in that vertical the separation is fixed with at least two support bars on the described collar.Laterally take collar apart,, can launch collar at an easy rate, thereby make it to come off because support bar is vertical.
Above-mentioned powder needle injection is characterized in that slotting on the inner face of described collar bottom side, and the bottle of double chamber bottle is along embedding in this fluting.
Above-mentioned powder needle injection is characterized in that slotting on the inner face of described collar upside, and the lower surface of syringe embeds in this fluting.
Above-mentioned powder needle injection, it is characterized in that the safety between described needle cylindrical unit and the injecting propeller are to constitute like this: on the rear end face of needle cylindrical unit pin is installed, is slotted on the injecting propeller, pin inserts in this fluting.Pin is when preventing that this product from not using, and the push rod of syringe enters syringe when not using, thereby has destroyed sealing device.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Embodiment 1:
With reference to accompanying drawing, a kind of powder needle injection comprises syringe 2 and ampoule that syringe needle 11 is installed, and ampoule is divided into two chambers, outer chamber 6 and powder chamber 7, and 6,7 of chambers and bottleneck are equipped with sealing device; The sealing device that nipple 20 parts of syringe are inserted in bottleneck is the hole clipping place of sealing-plug 5, and the syringe needle of syringe is installed in the outer chamber of ampoule; The safety that prevent the two relative motion are installed between syringe and the double chamber bottle.Sealing device between two chambers of double chamber bottle is intermediate thin, thick common ampoule plug all around.
The safety that prevent the two relative motion are installed between needle cylindrical unit and the injecting propeller.Safety are to constitute like this: a collar 4 is installed between syringe and double chamber bottle, the collar two ends respectively with double chamber bottle and syringe jacking.
The vertical commissure of collar is linked to each other by adhesive tape.The vertical separation is fixed with at least two support bars 3 on the collar.
Safety between needle cylindrical unit and the injecting propeller are to constitute like this: fixing pin 9 on the rear end face of needle cylindrical unit, slot 8 on the injecting propeller 1, and pin inserts in this fluting.
During use, tear the adhesive tape of collar, laterally take card figure apart, collar is peeled off from this product, promote syringe, the syringe nipple is clamp-oned to powder chamber direction, thereby made syringe needle thrust the inner cavity chamber of double chamber bottle and the ampoule plug between the powder chamber to the powder chamber; Promote injection putter again, make push rod destroy the pin of syringe, break through the restriction of pin, at this moment be stored in the powder chamber of the interior water preparation of syringe, shake product again, water preparation and powder are mixed, from double chamber bottle, transfer to syringe to be used for injection again from syringe needle injection double chamber bottle.
Embodiment 2:
As different from Example 1, present embodiment slots 10 on the inner face of collar bottom side, and the bottle of double chamber bottle is along embedding in this fluting.
Embodiment 3:
As different from Example 1, slot on the inner face of present embodiment collar upside, the lower surface of syringe embeds in this fluting.
