Abstract
The utility model provides an ideal double cavity automatic regulating pressure type dispensing injection needle. The utility model is characterized in that a pressure regulating tube is arranged beside the needle body of the normal syringe needle. When the utility model is used for infusing drug into a closed infusion bottle (drawing liquid from the closed infusion bottle), the added pressure regulating tube can fill gas into the bottle (exhaust gas) at any time. Therefore, no matter how many drugs the utility model puts into the infusion bottle, the work can be finished in one time. The utility model avoids the phenomenon of the damage of the infusion bottle and the hypodermic syringe caused by dispensing medicines. Compared with the prior art, the utility model has the advantages of flexible and convenient use, high work efficiency, simple structure, etc.
Description
This utility model belongs to medicine technology field, is a kind of two-chamber automatic pressure-regulating type injection needle that makes up a prescription.
Existing clinical pharmacy adopts is to use conventional injection needle in the sealing infusion bottle during injection (drawing liquid), because air can not convection current, goes rapidly in the bottle and causes injection (drawing liquid) difficulty into malleation (negative pressure).Particularly have only the gradation drawing liquid of employing or injection when a large amount of dosings, waste time and energy, inefficiency has slightly and does not cause infusion bottle, syringe to damage very easily.
The purpose of this utility model is a kind of syringe needle that makes up a prescription of injection in infusion bottle easily (or drawing liquid) rapidly of design, makes up a prescription in order to substitute conventional injection needle.
For reaching above-mentioned purpose, the main technical schemes that this utility model is taked is improved the existing conventional injection needle, the surge pipe that promptly be arranged in parallel on the needle body of conventional injection needle next door, thus constitute a kind of two-chamber automatic pressure-regulating type injection needle that makes up a prescription.
This utility model provides a kind of ideal two-chamber automatic pressure-regulating type injection needle that makes up a prescription for medicine technology field.This kind makes up a prescription injection needle owing to be provided with surge pipe on the needle body next door of conventional injection needle, therefore when injection (or drawing liquid) in the sealing infusion bottle, the surge pipe of setting up can be inflated (aerofluxus) at any time in bottle, therefore no matter in infusion bottle, add great dose, all can once finish, the stifled phenomenon of damaging infusion bottle, syringe of having cut off, thereby can reach the convenient purpose rapidly of making up a prescription, compared with prior art, this two-chamber automatic pressure-regulating type of this utility model make up a prescription injection needle have easy to use flexibly, can increase work efficiency the remarkable advantage that waits simple in structure.
Reach example in conjunction with the accompanying drawings and further specify the make up a prescription specific structural features of injection needle of two-chamber automatic pressure-regulating type of the present utility model.
Accompanying drawing is represented the make up a prescription general assembly structural representation of injection needle of this utility model two-chamber automatic pressure-regulating type.
Referring to accompanying drawing, this utility model two-chamber automatic pressure-regulating type injection needle that makes up a prescription comprises: main needle body 1, surge pipe 2, fixed cover 3.Main needle body 1 adopts conventional No. 12 injection needles, and surge pipe 2 adopts the hollow entry needle needle body of same model, and surge pipe 2 passes through fixed cover 3 secured in parallel on main needle body 1.
Claims (2)
1, a kind of two-chamber automatic pressure-regulating type injection needle that makes up a prescription has conventional injection needle, it is characterized in that also having surge pipe, and surge pipe is set in parallel in the needle body next door of conventional injection needle;
2, the two-chamber automatic pressure-regulating type as claimed in claim 1 injection needle that makes up a prescription is characterized in that described surge pipe adopts and the hollow entry needle needle body of described conventional injection needle same model, and surge pipe is fixed on the needle body of conventional injection needle by fixed cover.
