Description

The method of preventing thrombosis venous detaining needle and preventing thrombosis thereof
Technical field
The present invention relates to a kind of venous detaining needle, specifically a kind of method of preventing thrombosis venous detaining needle and preventing thrombosis thereof.
Background technology
Venous detaining needle is easy and simple to handle, is applicable to the puncture at any position, has alleviated the misery of patient's repeated localised puncture simultaneously, has alleviated nursing staff's workload, is deeply protected clinically to suffer from and welcomes.But venous detaining needle, suspending transfusion, and is retained in the process of vein blood vessel, because blood backflow is in flexible pipe and form thrombosis, thereby stop up infusion channel.In recent years, there is the patented product of many " positive pressure connector " and " counterflow-preventing ", but formation that all the time can not anti-tampon, utilize existing remaining needle to complete after transfusion, for pre-blockage resisting infusion channel, must use normal saline washing pipe, the complete rear heparin sodium tube sealing of using, within every 6 to 8 hours, carry out again siphunculus, therefore workload is very large, in addition, while using traditional remaining needle, in the time carrying out the care program of siphunculus, a large amount of thrombosis can be poured in the blood vessel of human body, produce very serious potential risk, and can produce acute vascular class disease, as there is red and swollen pain in patient's injection site, bring injury to patient, there is the defect that quality of medical care is not high, further, above-mentioned care program, expense, the expense of tube-sealing solution and the expense of labor of nursing of the washing pipe liquid of need to paying wages, these expenses are well beyond the price of remaining needle itself, therefore medical treatment cost is higher.
Patent Office of the People's Republic of China disclosed on October 2nd, 2013 open (bulletin) number iscN103330970A, patent name is the patent of self-styled preventing thrombosis venous detaining needle and using method thereof, the invention discloses a kind of self-styled preventing thrombosis venous detaining needle and using method thereof, this self-styled preventing thrombosis venous detaining needle comprises needle stand, is arranged on the conduit of needle stand front end and axially passes the puncture nook closing member of described needle stand and conduit, the inner chamber of described needle stand is cut off part and is divided into plemum and transfusing chamber two parts, described transfusing chamber is communicated with described conduit, and described obstruct section adopts medical encapsulant; Described obstruct section is provided with seepage channel, and in the time that described plemum and transfusing chamber exist pressure differential, the liquid in described plemum can flow into described transfusing chamber through described seepage channel automatic slowly.Self-styled preventing thrombosis venous detaining needle of the present invention and using method thereof have following useful technique effect; When operation suspension is infused routinely, automatic pipe sealing, the liquid in plemum slowly flows into transfusing chamber by described seepage channel; Along with the pressure reduction between plemum and transfusing chamber reduces, percolation flow velocity also can slow down thereupon, makes described plemum can maintain for a long time malleation.This Patent Application Publication, is that the applicant researches and develops, its technical scheme, the greatest drawback existing is: this patent, in the process using, be unable to do without transfusion needle, if be directly connected with needle stand with the joint of transfusion device, cannot infuse, and above-mentioned patent structure complexity, technological requirement is high, when use, operate loaded down with trivial details, therefore for above-mentioned defect, therefore researched and developed this patent, above-mentioned technical scheme is improved, to meet the needs of real work.
