Abstract
The invention discloses an anti-reflux remaining needle, comprising a remaining needle holder, a remaining flexible pipe, an extension pipe, an extension pipe seat and a liquid stopping clamp, wherein the liquid stopping clamp is arranged on the extension pipe; the extension pipe is connected between the extension pipe seat and the remaining needle holder; the extension pipe is a multi-cavity catheter which comprises at least two channels. According to the anti-reflux remaining needle, the structure of a multi-channel extension pipe is tactfully used, not only is the situation that a medical liquid dripping channel cannot be blocked in the infusion process sufficiently guaranteed, and the dripping speed and smoothness of medical liquid are guaranteed, but also a micro gap can be formed in the joint position between the outer wall and each separate inner wall of the extension pipe due to the fact that the multi-channel extension pipe is clamped through the liquid stopping clamp after the infusion operation is finished and paused every time, so that a microporous channel is formed by the micro gap between the extension pipe and the bottom part of the chamber of the remaining needle holder; a positive pressure chamber is formed through the upper part of the extension pipe and the extension pipe seat, therefore the blood reflux can be effectively and reliably prevented through slow penetration of the medical liquid, stored in the positive pressure chamber, via the microporous channel, and an anti-thrombotic purpose is achieved.
Description
Technical field
The present invention relates to remaining needle, belong to technical field of medical instruments.
Background technology
All medicinal liquids almost can be inputted human body by blood vessel by transfusion, realize treatment and prophylactic object, in clinical, for avoiding repeatedly the puncture damage causing blood vessel and the misery reducing patient, also for alleviating the manipulation strength of medical personnel, remaining needle (pipe) technology is generally employed.The remaining needle of present Clinical practice generally comprises indwelling needle, indwelling flexible pipe, extension tube, prolongation base, the liquid stopping clamp be installed in extension tube, in the remaining needle of this structure composition, its extension tube is all adopt single lumen catheter, in transfusion time-out process, make prolongation base and formed between indwelling needle and indwelling flexible pipe to cut off by the liquid stopping clamp in operation extension tube, avoid air and foreign body to enter into patient blood by indwelling flexible pipe.But due to the effect of human vein pressure, in the process suspending transfusion, blood is understood adverse current and enters into indwelling flexible pipe and indwelling needle, enter into even the liquid stopping clamp of extension tube with lower part, time one length will form thrombosis in these positions, need to use heparin sodium to carry out anticoagulant lock to indwelling needle tubing, to reach the object not producing thromboembolism in indwelling needle tubing, and all need to use acupuncture to be connected in transfusion with the process of indwelling needle tubing being carried out to anticoagulant lock, so virtually add workload and the labor intensity of nurse, also there is the danger that medical personnel are accidentally injured by acupuncture simultaneously, for the existence of the problems referred to above, Chinese patent CN104043162A discloses the patent application that a kind of name is called the method for preventing thrombosis venous detaining needle and preventing thrombosis thereof, this preventing thrombosis venous detaining needle comprises indwelling needle, indwelling flexible pipe, puncture needle and extension tube, the sidewall of indwelling needle is provided with medicinal liquid input port, one end of indwelling needle is provided with medicinal liquid delivery outlet, indwelling flexible pipe is connected with the medicinal liquid delivery outlet of indwelling needle, the needle point of puncture needle penetrates in indwelling needle from the other end of indwelling needle, pass from indwelling flexible pipe through medicinal liquid delivery outlet, also comprise conduction hose, drainage strip and fixture, one end of described conduction hose is connected with medicinal liquid input port, the other end is connected with one end of extension tube, drainage strip is located in conduction hose, fixture is clipped on conduction hose.But this patent application has following defect: the 1. setting of drainage tube and drainage strip, cause complex process, manufacturing cost is high; 2. the existence of drainage tube and drainage strip affects drip velocity and the smoothness of infusion process herb liquid, cause even the obstruction of medicine liquid-dripping passage, the drainage thread that water wetted material is made especially has fibre shedding and is dissolved in the possibility in needle stand cavity and indwelling flexible pipe, fibrous foreign matter is caused to enter in blood of human body with liquid, serious harm health.
Summary of the invention
The object of the invention is to for above-mentioned existing problems and deficiency, provide that a kind of novel structure is simple, cost of manufacture is cheap, use safety there is the reverse flow resistant indwelling needle that effectively and for a long time can prevent blood backflow of reliable positive-pressure function.
Technical scheme of the present invention is achieved in that
Reverse flow resistant indwelling needle of the present invention, comprise indwelling needle, indwelling flexible pipe, extension tube and extend base, the liquid stopping clamp be installed in extension tube, extension tube is connected to and extends between base and indwelling needle, it is characterized in that described extension tube is the multi-cavity catheter with at least two passages.
The structure of described multichannel drainage tube is varied, both can be that above-mentioned extension tube is for having twin-channel double channel catheter, this double channel catheter is by by one-body molded cross section in body, linearly type or arc separation inwall are formed, also can be above-mentioned extension tube for having three-channel three cavities conduit pipe, this three cavities conduit pipe is by being formed by the separation inwall of one-body molded cross section in body linearly type or arc line type or interlaced linear type or cross one another arc line type.
The present invention is owing to adopting the structure of multichannel extension tube, both can utilize indwelling needle and extend base and combine, ensure the phenomenon that there will not be after using puncture needle to puncture outside blood backflow indwelling needle cavity, make medical personnel can extracting easily with one-handed performance puncture needle, and effectively prevent the cross infection of patient and medical personnel, nor there will be the phenomenon of tenderness patient's blood vessel, and avoid surrounding to the pollution of medicinal liquid and blood, utilize and extend the object that base realizes safe infusion and no-needle transfusion.Utilize again the structure of multichannel extension tube dexterously, both fully ensured that infusion process herb liquid instillation passage there will not be choking phenomenon, ensure drip velocity and the smoothness of medicinal liquid, connect the micro-interstices that position formed between extension tube and indwelling needle cavity bottom, form micro channel in the clamping of multichannel extension tube at extension tube outer wall and each inwall of separating by liquid stopping clamp after can suspending infuse again at every turn, and the malleation chamber by utilizing the quick acting of button of infusing or additional syringe needle to produce in extension tube top with prolongation base, the medicinal liquid of this malleation chamber indoor storage is utilized effectively and reliably to prevent blood backflow in indwelling flexible pipe by the slow infiltration of micro channel, reach the object of preventing thrombosis.And operation is quite simple, is easy to grasp, is conducive to applying at each different medical unit.And structure of the present invention and single reliable, cost of manufacture is cheap, practical, is beneficial to and popularizes.
Below in conjunction with accompanying drawing, the present invention is further illustrated.
