Abstract
The utility model discloses a needle for injection. The needle comprises a needle stand and a needle body, wherein the needle stand is connected with the rear end of the needle body, the tip of the needle body is a blind end, and the lateral surface of the front end of the needle body is provided with a plurality of needle holes. When the needle is used, after solution is extracted by using a sterile syringe, the needle is inserted into a bottle plug, a piston handle is held to propel the solution into the sealed bottle quickly, and the medicament is dissolved and diluted by using the multi-hole needle; and because of spraying pressure generated by multiple holes, the solution is sucked back, and the powder can be instantaneously dissolved by a few times of propelling and suction. In addition, because the needle holes are formed in the lateral surface, when the needle passes through the bottle plug, rubber granules are not blended into the medicinal liquid. The needle has a simple structure, and is convenient to operate; and when the needle is used, the operation of a nurse is more labor-saving, the pollution to the environment is low, and the dissolving and diluting speed of the medicament can be effectively increased, the dissolving time of the medicament is shortened so that the working strength of nursing personnel is greatly reduced, the nursing quality is improved, the working efficiency is improved, and the labor intensity of the nurse is reduced.
Description
Technical field
This utility model relates to a kind of injection syringe needle.
Background technology
In the disease treatment process, seal bottled medicine powder and be widely used in clinical.Medicine powder needs with physiological saline solution or water for injection (medicine special solvent) powder to be dissolved, and treats that fully medicinal liquid is drawn in the dissolving back.In the prior art, clinical nurse in the common practice of preparation during medicine powder is: inject in the bottle with the manual drawing liquid of syringe, treat that a bottle interior powder dissolves after, the reuse syringe is extracted the medicinal liquid in this medicine bottle out.But in actual applications; ease of solubility difference because of different pharmaceutical; the nurse runs into difficult dissolved drug at some medicine powder of preparation through regular meeting; when finding that it dissolves back aspiration medicinal liquid or the interior medicinal liquid of suction syringe has injected in big liquid bottles; the syringe needle of obstruction phenomenon is often arranged; cause medicinal liquid suction or injection not smooth, if firmly inject the injection that also can cause medicinal liquid.At this phenomenon, the method for taking usually at present, the one, when the dissolving medicine powder, prolong dissolution time, it is fully dissolved.The 2nd, when running into the syringe needle obstruction, change syringe needle.These two kinds of processing methods all have drawback, and the former has prolonged the working time, has reduced work efficiency, need the medicine of preparation more in daystart treatment, when workload is big, and especially big to the critical patient drug dose, time requirement is urgent, can influence the progress of work.The latter has a considerable amount of medicinal liquids to overflow, cause with drug dose and reduce, concentration reduces, caused the waste of medical resource, directly affect the treatment, and increased the chance of polluting, particularly antitumor drug is excessive, can cause environmental pollution, to staff's the healthy harm that causes different journeys.
In addition, when the syringe needle that uses clinically passes bottle stopper at present, can make rubber grain sneak into medicinal liquid, by syringe needle suction needle tubing, rubber particle can enter in people's the body along with medicinal liquid during injection, influences therapeutic effect, even produces untoward reaction.
For the foregoing reasons, be necessary in clinical position, syringe needle to be made improvement, to address the above problem.
Summary of the invention
At above-mentioned prior art, this utility model provides a kind of injection syringe needle, and it can realize the quick dissolving of powder, and can effectively avoid syringe needle obstruction, rubber grain to sneak into phenomenons such as medicinal liquid.
This utility model is achieved through the following technical solutions:
A kind of injection syringe needle comprises needle stand and needle body, and needle stand is connected needle rear end, and the needle body tip is cecum (sealing), and needle body front end side is provided with some pin holes.
During use, behind asepsis injector draw dissolved liquid, syringe needle of the present utility model is inserted bottle stopper, hold piston handle lysate is advanced air-tight bottle fast, utilize porous syringe needle dissolved dilution medicine, because the fountain pressure that porous produces, resorption then, push away suction repeatedly several times, but moment is dissolved powder.As the powder in bulk that condenses, can adjust needle position and aim at coagula.Though conventional syringe needle also can come the accelerate dissolution powder by pushing away suction mode several times repeatedly, it only has a pin hole, poor effect, and this utility model has several pin holes, effect is better.In addition, pin hole of the present utility model is driveed in the side, when syringe needle passes bottle stopper, can not make rubber grain sneak into medicinal liquid.
Needle head structure of the present utility model is simple, and is easy to operate, quick; Laborsaving and the of low pollution environment of nurse operation can effectively improve the speed of medicine dissolution dilution, shortens the medicine dissolution time, has significantly reduced nursing staff's working strength, has improved nursing quality, increases work efficiency, and has reduced nurse's labor intensity.Simultaneously, can thoroughly extract the residual liquor in the medicine bottle out, reduce material consumption, save medical resource, avoid unnecessary waste.In addition, when syringe needle passes bottle stopper, can not carry rubber grain, make it sneak into medicinal liquid, and, influence therapeutic effect, guarantee patient's medical safety, avoid the generation of medical tangle further along with medicinal liquid enters in people's the body.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1, needle stand; 2, needle body; 3, needle body tip; 4, pin hole.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
A kind of injection syringe needle comprises needle stand 1 and needle body 2, and as shown in Figure 1, needle stand 1 is connected needle body 2 rear ends, and needle body most advanced and sophisticated 3 is cecum (sealing), and needle body 2 front end sides are provided with some pin holes 4 (three).
During use, behind asepsis injector draw dissolved liquid, syringe needle is inserted bottle stopper, hold piston handle lysate is advanced air-tight bottle fast, utilize porous syringe needle dissolved dilution medicine, because the fountain pressure that porous produces, resorption pushes away suction several times repeatedly then, but moment is dissolved powder.As the powder in bulk that condenses, can adjust needle position and aim at coagula.In addition, pin hole 4 is driveed in the side, when syringe needle passes bottle stopper, can not make rubber grain sneak into medicinal liquid.
