Description

A kind of remaining needle with slow release malleation
Technical field
This utility model relates to single use medical apparatus and instruments, especially relates to a kind of remaining needle with slow release malleation.
Background technology
The single use venous detaining needle of clinical unit of domestic each medical institutions Clinical practice, after transfusion terminates, even need carry out tube sealing operation, in order to avoid cause plugging phenomenon because managing interior formation blood coagulation, but in actual application, often because of patient moving and blood infiltration and cause blood to enter to put in pipe, as failed washing pipe before carrying out the transfusion of second day, or established sludged blood is poured Ink vessel transfusing, very easily cause the vascularization thromboembolism that blood blocks in cyclic process, bring to patient and injure even life-threatening greatly, though have to prevent blood coagulation from injecting the anticoagulant medicines such as heparin sodium to patient, can have anticoagulant drug allergy patients such as heparin sodiums, also useful normal saline carries out tube sealing, but its tube sealing limited time, repeatedly need carry out tube sealing, in addition, nurse operation is improper also very easily causes plugging phenomenon, just like positive pressure connector device on existing market, also have in pipe and place fine fibre drain etc. technology, it also can only be had malleation at that time, or obtain tension because of clip, pressure is too small, medicinal liquid release is not come, after not having a few minutes, medicinal liquid has not just flow out, still easily plugging is formed, how solving intravascular coagulation prevents clot generation from being the current difficult problem facing solution.
Utility model content
The purpose of this utility model is to provide a kind of remaining needle with band slow release malleation, the medicinal liquid of certain volume, lasting pressure source can be provided, slow releasing medicinal liquid that simultaneously can be stable, prevent from forming sludged blood in indwelling tube, plugging phenomenon is avoided to occur, extend service life of remaining needle, thus the clot because being formed also can be avoided to pour in the blood circulation of patient cause secondary injury.
For achieving the above object, this utility model adopts following technical scheme: comprise indwelling needle assembly, double channel catheter, vessel clamp, Y type positive pressure connector and liquid reservoir, indwelling needle assembly comprises needle shield, conduit tube component and needle assembly, vessel clamp is placed on double channel catheter, the loculus face of conduit snaps in the draw-in groove of vessel clamp, the two ends of double channel catheter respectively with the conduit tube component of indwelling needle assembly ytype angle stake is firmly connected with end interface under Y type positive pressure connector joint base, liquid reservoir is rotatably connected on the angle stake of Y type positive pressure connector, it is characterized in that: double channel catheter is small one and large one double channel catheter, its large chamber is conventional infusion passage, loculus is a micro-aperture, during indwelling after large cavities conduit pipe is closed by vessel clamp folder, its positive pressure connector and the hydraulic pressure mineralization pressure of liquid reservoir after release are the slow sepage passage of medicinal liquid.
The liquid reservoir of the remaining needle of described band slow release malleation is the syringe of its rear portion inner chamber with spring, and syringe is compressed in aspiration medicinal liquid rear spring, releasing syringe core bar, and spring and release pressure make remaining needle form positive pressure devices.
The double channel catheter of the remaining needle of described band slow release malleation, its loculus aperture is between 0.001mm ~ 0.1mm.
The Y type positive pressure connector of the remaining needle of described band slow release malleation, be made up of the Y type overcoat of band two interpolation type female Luer, silicon capsule, spring and joint base, also Y type positive pressure connector can be substituted by threeway Connection Block and single positive pressure connector, single positive pressure connector is made up of the straight type overcoat with 1 interpolation type female Luer, silicon capsule, spring and joint base, and the spring in Y type positive pressure connector and single positive pressure connector also can not be equipped with.
Spring in the syringe of the remaining needle of described band slow release malleation, may also be elasticity reservoir or reservoir bag or elastomer and replaces.
The vessel clamp of the remaining needle of described band slow release malleation, in the middle part of the lower convexity of upper and lower therebetween sandwich part, opens a draw-in groove matched with the external diameter of aperture outer wall along duct direction.
The appearance of the double channel catheter of the remaining needle of described band slow release malleation can increase one deck lucifuge layer, the syringe jacket of the overcoat of catheter block, Y type or straight type positive pressure connector, joint base and threeway Connection Block, liquid reservoir adopts can be made the material of lucifuge, or also adopts and increase one deck lucifuge layer outside.
The remaining needle of band slow release malleation of the present utility model, using with the remaining needle on existing market distinguishes not quite, function is but completely different, operate as follows: the transfusion needle of being joined by transfusion device inserts on the piercing devices of the calparine cap of band slow release positive pressure devices remaining needle after taking out its sheath, transfusion device device needle for inserting bottle is inserted on medicine bottle mouth, after making transfusion device and band slow release positive pressure devices remaining needle of the present utility model be full of medicinal liquid, take out remaining needle sheath, close transfusion device actuator, wound surface sterilization is carried out by retained needle puncture art operating process, pumpback needle assembly after blood back is shown in venipuncture, inserting needle, extract needle assembly, fixing wait operate after infuse, on arbitrary time point in infusion process, slowly pull core bar aspiration medicinal liquid is in syringe jacket, to core bar draw-in groove position, after rotation core bar one angle makes four of core bar muscle depart from the protecting cover line of rabbet joint, spring is compressed, core bar is stuck on protecting cover, at the end of transfusion closes on, closure catheter for closing is pressed from both sides, non-for transfusion device end connector is separated with positive pressure connector, one malleation is formed in positive pressure connector, afterwards four of core bar muscle are returned in the protecting cover line of rabbet joint, namely being released of Compress Spring, medicinal liquid in syringe urceolus is extruded, form another burst of malleation, so just make this utility model have two bursts of malleations simultaneously and extrude medicinal liquid simultaneously, the medicinal liquid be extruded in this utility model pipe flow to inlying catheter along the micropore of double channel catheter, also be formed while flowing to inlying catheter and be greater than human vein pressure and infiltrate vein, make this utility model remain medicinal liquid always and infiltrate venous patient blood vessel, because the medicine liquid volume of positive pressure connector release is limited, the limited time of release, after increasing the medicinal liquid of liquid reservoir release, just can greatly extend release time of the present utility model, thus can more effectively condense at inlying catheter by anti-Hemostatic Oral Liquid, and then plugging can be avoided to prevent thrombosis, prevent secondary injury, nurse can also be exempted like this every the tube sealing of 6-8 hour/time, washing pipe, alleviate its workload.
