Abstract
The invention discloses a disposable air-filtering type medicine dissolving needle, which comprises a needle tip, a needle body and a needle tail, wherein the needle tip is provided with an air outlet and a liquid inlet; an air inlet channel communicated with the air outlet is formed on the inner wall of the liquid inlet channel of the needle body; an air inlet communicated with the air inlet channel is formed in a joint between the needle body and the needle tail; an air filter with an air-filtering film is arranged on the air inlet; and the needle tail is provided with an inner conical connector connected with an injector. By the air outlet in the needle tip of the medicine dissolving needle, inner pressure intensity and outer pressure intensity of an ampere bottle are equal, so that a medicine dispensing person can directly extract water for injection and inject the water into the ampere bottle with a powder injection during dissolving of medicines; therefore, time and labor are saved; meanwhile, the air filter prevents a large number of particles from air from entering the bottle, so medicine liquid is safer. The disposable air-filtering type medicine dissolving needle has a rational design and a novel structure and is convenient to operate; furthermore, the working efficiency of nurses is improved and the safety of medicines is enhanced.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of disposable empty formula of crossing is dissolved the medicine pin.
Background technology
When making up a prescription clinically at present,, need dissolve earlier particularly for injectable powder, intramuscular injection then, or add and carry out intravenous injection in other diluent.Traditional method is to use the molten syringe that has stainless pin, in dissolving syringe, injects air in advance, after the absorption diluent dissolves injectable powder, it is released again.Repeated localised puncture is just carried out to the bottle closure of rubber of apothecary jar in front and back like this, easily rubber particle and airborne microgranule is brought in the medicinal liquid, and the patient is caused unnecessary damages.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to prior art, provides a kind of reasonable in design, novel structure, and the easy to operate disposable empty formula of crossing is dissolved the medicine pin.
Technical problem to be solved by this invention is to realize through following technical scheme; The present invention is that a kind of disposable empty formula of crossing is dissolved the medicine pin; Be characterized in: it comprises needle point, needle body and backshank; Needle point is provided with venthole and inlet opening, and the inwall of the feed pathway of needle body is provided with the inlet channel that is connected with venthole, and needle body is provided with the air inlet that is connected with inlet channel with the backshank joint; Air inlet is provided with the air filter of band air filtration film, and described backshank is provided with the female cone joint that joins with syringe.
Technical problem to be solved by this invention can also further realize that the above-described disposable empty formula of crossing is dissolved the medicine pin through following technical scheme, and be characterized in: needle body and backshank joint are provided with controls the wing.
Technical problem to be solved by this invention can also further realize that the above-described disposable empty formula of crossing is dissolved the medicine pin, is characterized in: sheath is housed on the needle body through following technical scheme.
The present invention makes peace cut open bottle inside and outside pressure to equate that the pharmacist particularly cuts open the interior injectable powder of bottle to peace when dissolving medicine, can directly extract water for injection injection powder injection bottle, save time through dissolving venthole on the medicine pin needle point, laborsaving.Simultaneously air filter has stopped in a large number and has got in the bottle from airborne microgranule, makes medicinal liquid safer.Compared with prior art, it is reasonable in design, and novel structure is easy to operate, has improved nurse's work efficiency, has increased the safety of medicine.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
The specific embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not constitute restriction to its right.
See figures.1.and.2; A kind of disposable empty formula of crossing is dissolved the medicine pin, and it comprises needle point 1, needle body 2 and backshank 5, and needle point 1 is provided with venthole 6 and inlet opening 8; The inwall of the feed pathway 9 of needle body 2 is provided with the inlet channel 7 that is connected with venthole 6; Needle body 2 is provided with the air inlet that is connected with inlet channel 7 with backshank 5 joints, and air inlet is provided with the air filter 3 of band air filtration film, and described backshank 5 is provided with the female cone joint 10 that joins with syringe; The tapering of female cone joint 10 can be 6:100, and convenient and syringe is used.Needle body 2 is provided with backshank 5 joints and controls the wing 4, makes things convenient for the nurse that bottle stopper is punctured during use.On the needle body 2 sheath is housed, the protection before cutting tip is used prevents that inlet opening 8 and venthole 6 are by germ contamination.
Before using female cone joint 10 is linked to each other with syringe and can use, during use, extract water for injection through the inlet opening 8 that dissolves on the medicine pin needle point 1; Then needle body 2 is punctured in the powder pin bottle, when needing QI invigorating, air passes from inlet channel 7 through the air filter 3 of band air filtration film; Come out the venthole 6 from needle point 1, make peace cut open bottle inside and outside pressure and equate, play the effect of balance external and internal pressure; Make the nurse be easy to water for injection is injected the injectable powder apothecary jar; Do not need the nurse that the bottle closure of rubber of apothecary jar is carried out repeated localised puncture, easy to use, improved work efficiency.Air filter 3 has stopped in a large number from airborne microgranule and has got in the bottle, makes medicinal liquid safer.
