Abstract
The utility model relates to a medical needle which can avoid bringing in impurities. A drug inlet hole is provided at one side of the needle stalk; a solid needle is disposed on one side of the drug inlet hole; and a depression is arranged in the solid needle installing at the other side of the position where the drug inlet hole installed. A heat sealing needle tying is inserted at the other side of the needle stalk; an inlet channel and an outlet channel which is installed at a line are provided in the needle stalk connected with each other. The present utility model has advantages of simple structure, ease in operation, low cost and corresponding with the principle of single use which can also avoids waste of medical solution caused by entrapped impurities and increases reaction rate of hot source, therefor ensuring security to human in the course of transfusion.
Description
Technical field
This utility model relates to technical field of medical, particularly relates to the medical needle of avoiding bringing into impurity that uses in the intravenous medicine preparation.
Background technology
In the preparation of medical domain clinical nursing activity medium-sized vein flow of infusate is one of modal nursing procedure in the clinical care, prior art medical needle have a variety of, medicine when preparation use medical needle form by the pin stalk and the pintle that can connect together, and the access way that is interconnected arranged, the head of pin stalk is the inclined-plane, at present, what intravenous medicine when preparation was the most frequently used is No. 9 injection needles of common inclined-plane hollow, this syringe needle is sharper, penetration Resistance is little, but add plastic sheeting and make because the bottle stopper of medicine powder is rubber or rubber, when cannot see rubber and plastic particles with No. 9 sharp some finding of naked eye of cutting and the naked eyes in injection needle puncture its inclined-plane of bottle stopper, thereby, carry these impurity in the medicinal liquid secretly, cause the liquid waste medical treatment cost to rise if therefore discard it.In addition, if direct intravenous medicinal liquid, then may be imported into to increase the reaction of thermal source incidence rate, serious harm patient's health in the human body.
The applying date: on July 26th, 1996, application number: 9621789.8, patent as shown in Figure 1 " can to avoid sucking the medical needle of impurity ", the medical needle 6 of prior art cover 2 by pin stalk 1 time is logical, and filter 3 is gone up to lead to and covered 4, pintle 5 constitutes, this utility model is provided with filter membrane 3 in the middle of pin stalk 1 and pintle 5 can prevent effectively that diameter from entering in the medicinal liquid greater than 15 μ m microgranules, has reduced once more and has polluted, the safety to human body of guaranteeing to infuse.
But the medical needle of this patented technology has following defective: manufacturing process is complicated, and cost rises, and does not meet disposable using priciple.
Summary of the invention
The purpose of this utility model provides a kind of manufacturing process simple, can avoid bringing into the medical needle of impurity again.
In order to reach the purpose of this utility model, we adopt following technical scheme: a kind of medical needle of avoiding bringing into impurity, it is characterized in that obstructing 1 one sides at pin is provided with medicine feeding hole 8, side at medicine feeding hole 8 is provided with solid needle point 9, depression 10 is set on the solid needle point 9 in the another side of medicine feeding hole 8 present positions, the another side socket heat sealing pintle 5 of pin stalk 1, and have the access way that is interconnected, access way is positioned on the straight line and constitutes.
The described medical needle of avoiding bringing into impurity is characterized in that medicine feeding hole 8 the bests are " ellipse garden " shape, and the hole that Any shape also can be set constitutes.
The described medical needle of avoiding bringing into impurity is characterized in that, depression 10 is to be made of V-arrangement shape depression.
Advantage of the present utility model: simple in structure, easy operating.Cost is low, meets disposable using priciple.Can avoid impurity band to cause liquid waste in being used as medicine again and increase the reaction incidence rate of thermal source, the safety of guaranteeing to infuse human body.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in detail.As shown in Figure 2 to Figure 3, this utility model medical needle 7 is to be made of pin stalk 1, pintle 5.Pin stalk 1 adopts stainless steel to make, and is set to " ellipse garden " shape in head one side the best of pin stalk 1, and the hole that Any shape also can be set constitutes.Medicine feeding hole 8, side cutting tapered solid needle point 9 at medicine feeding hole 8, the bottle stopper of can avoiding puncturing cuts some finding of naked eye and naked eyes be cannot see rubber and plastic particles is brought in the medicine, on the solid needle point 9 in the another side of medicine feeding hole 8 present positions, wash out V-arrangement shape depression 10, form two side edges to reduce penetration Resistance, the another side socket heat sealing pintle 5 of pin stalk 1 forms, and has the access way that is interconnected, and access way is positioned on the straight line.Pintle 5 adopts medical plastic to make.When intravenous medicine is prepared during with this utility model medical needle 7 puncture bottle stoppers owing to adopt side opening, most advanced and sophisticated solid, solid needle point 9 is that taper-cut can avoid rubber particle to bring in the medicine, thereby solved pollution problems once more, it is sharper that two this syringe needles of side edge of V-arrangement shape depression 10 formation are set on the solid needle point 9, and penetration Resistance is little.This utility model medical needle 7 manufacturing process are simple, and cost is low, meet disposable using priciple.Can avoid impurity band to cause liquid waste in being used as medicine again and increase the reaction incidence rate of thermal source, the safety of guaranteeing to infuse human body.
