Background technique
Venous detaining needle is easy to operate, suitable for the puncture at the multiple positions of human body, while alleviating what patient punctured repeatedly
Pain alleviates the workload of nursing staff, clinically deep to be suffered from welcome by shield.But venous detaining needle is infused in pause, and is stayed
It sets during vein blood vessel, due to having blood backflow into hose and forming thrombus, to block infusion channel.In recent years
Come, there is the patented product of many " positive pressure connectors " and " counterflow-preventing ", but always cannot anti-tampon formation, stayed using existing
Set needle complete infusion after, for pre- anti-clogging infusion channel, it is necessary to use physiological saline washing pipe, then use heparin sodium tube sealing, every 6 to
Duplicate tube sealing operation is carried out again within 8 hours, therefore workload is very big, in addition, carrying out siphunculus when using traditional remaining needle
When care program, a large amount of thrombus can be poured in the blood vessel of human body, generate potential risk very serious, and can generate
Acute vascular class disease brings injury to patient, it is not high that there are quality of medical care if red and swollen pain occurs in the injection site of patient
Defect.Furthermore above-mentioned care program, the expense of labor of need the to pay wages expense of washing pipe liquid, the expense of tube-sealing solution and nursing,
These expenses are well beyond the price of remaining needle itself, therefore medical treatment cost is higher.
Therefore it is generally provided with a flow-stopping clip on the conduit of present remaining needle, liquid stopping clamp is equivalent on conduit one and opens
It closes, fluid stopping accompanies one and stitched by wide to narrow clamping, and clamping seam includes wider throughput and relatively narrow fluid stopping portion, works as remaining needle
Conduit be located at clamping seam throughput when, liquid can flow freely in conduit；When the conduit of remaining needle is located at clamping seam
When fluid stopping portion, flow-stopping clip radially compresses deformation of guide tube, and complete liquid barrier flows in conduit.However due in human vas
Blood pressure is greater than external air pressure, along with the influence of many factors, when the moment conduit of fluid stopping clip closure elasticity and resorption meeting
There is micro blood to enter in the conduit of remaining needle, indwelling time is too long just to will form thrombus, does harm to huamn body.
