Description

Multi-functional remaining needle
Technical field
The utility model belongs to medical instruments field, more particularly, to a kind of multi-functional remaining needle.
Background technology
Venous detaining needle is also known as venous catheter needle, and the building block of core includes that can be retained in leading for endovascular softness The guiding puncture needle core of pipe and stainless steel, when use conduit and needle core are punctured into together it is intravascular, when conduit fully enters After blood vessel, needle core is withdrawn out, only by soft catheter retaining in the blood vessels to carry out infusion treatment, has and is easy to puncture, phase The puncture technique of pass is easy study protection patient's blood vessel, mitigates patient's pain, is comfortable on, improves patient satisfaction and nursing Quality is reduced and is punctured and not medication on time, avoid reacting between drug, reduce expense, subtract when avoiding daily repeatedly interruption infusion Few scalp needle puncture causes the effect of the cost of exudation treatment more and more to be welcome in recent years, and still, current stays The device that the needle core that needle is withdrawn out lacks safe disposal is set, is accidentally easy for pricking medical staff, it is serious to be also easy to feel Disease is contaminated, the needle core arbitrarily abandoned is also easy to prick the treatment people of Biohazard Waste, serious to be also easy infectious disease, separately Outside, the time that remaining needle uses is longer, needs the arm etc. for staying in patient for a long time, currently without good fixing means, It is easy to fall off, the patient of especially some moods agitation is easy to pull out remaining needle, and remaining needle needs again once falling off It is punctured, increases the workload of medical staff, also bring pain to patient, in addition, being frequently necessary in clinical position Blood test is carried out to patient, needs to be additionally carried out puncture blood drawing, the effect of remaining needle is not also fully played.
105833388 A of CN disclose " a kind of safety indwelling needle ", by the way that remaining needle security component is arranged, can will wear Pricker is hidden in casing, so as to avoid the puncture needle for piercing patient hurt operator or other people, increase indwelling The safety that needle uses, but the structure of this safety indwelling needle is relatively complicated, and can not realize other functions.
In addition, also having after piercing, the button in remaining needle is set to by pressing, interior needle is pulled in into needle by spring Set is internal, is received in wherein (such as JP Laid-Open 10-52499 documents, patent application publication CN 102512728A);Also spring needle point protection mechanism is set to the inside of outer Needle sleeve, passes through needle in extraction, needle point protection Mechanism is detached from outer Needle sleeve, and the front end of interior needle is covered (such as patent publication No. CN 101011613A);These are all needed It to be realized using to spring, if spring can not be successfully deformation reset, cannot achieve the protection to draw point needle point, therefore not enough Reliably.
CN 103285450A disclose " a kind of multi-functional remaining needle ", including sheath assembly and draw point component, innovative point It is:Further include counterflow-preventing valve, Anti-stabbing safety device, Needleless barotropic connector, wherein the counterflow-preventing valve setting is covering Tube socket lumen, and the hose front end being connected to casing seat is located axially in casing seat, the Anti-stabbing safety device setting exists In draw point seat, the Needleless barotropic connector is arranged on external connector;And Anti-stabbing safety device is pacified for no spring Anti-stabbing Full device, Needleless barotropic connector are no spring Needleless barotropic connector.Closed structure can anti-Hemostatic Oral Liquid be excessive pollutes;It keeps away Exempt to stab medical staff's infectious disease when draw point is extracted;Counterflow-preventing duplicate protection avoids single measure from easy unexpected situation, work occur Make securely and reliably, to avoid the problem that blood backflow is brought, improves medical staff's working efficiency.Meanwhile non-spring structure avoids bullet Spring structure brings corrosion problem, more safety and sanitation, it is ensured that remaining needle is stable and reliable in work, but this multi-functional remaining needle according to So there is a problem of that structure is complex, meanwhile, when needing to carry out blood test to patient, still need to be additionally carried out puncture Blood drawing, the effect of remaining needle are not also fully played.
204601258 U of CN disclose " a kind of multi-functional remaining needle ", including positive pressure connector, the side of the positive pressure connector It is provided with calparine pipe on wall, blood-taking device, the blood-taking device and positive pressure are also movably installed on the side wall of the positive pressure connector Connector is connected so that the standby blood sampling function of tool of needles staying on vein, to reduce patient due to puncturing the pain brought twice, still, this The multi-functional remaining needle of kind still remains the more complicated problem of structure, and function is also not complete enough, and there is presently no collection various functions to be All over the body and the simpler multi-functional remaining needle of structure.
