Also comprise batcher, described batcher is located in indwelling needle, and the needle point of described puncture needle passes from batcher.
The other end of described extension tube is connected with transfusion device by calparine cap or positive pressure connector.
Described drainage strip is the drainage thread be made up of water wetted material.
Described drainage strip is bonded on the inwall of conduction hose.
Described fixture is intermediate plate, liquid stopping clamp or actuator, preferred intermediate plate.
The length of described conduction hose is 2 ~ 5mm, and the diameter of conduction hose is not more than the external diameter of extension tube.
The length of described drainage strip is not less than the length of conduction hose, and the diameter of drainage strip is not more than 0.1mm.
The spacing of described batcher and medicinal liquid delivery outlet is 1 ~ 2mm.
The beneficial effects of the utility model:
Owing to adopting above-mentioned version, set up conduction hose, drainage strip and fixture, after conduction hose clamps by fixture, medicinal liquid stops flowing, again the actuator on transfusion device cuts out, to make in extension tube hydraulic pressure strengthen, effect under, the medicinal liquid in extension tube penetrates in indwelling flexible pipe by drainage strip, thus malleation is obtained discharge slowly, substantially prolongs the time keeping malleation, effectively prevent the backflow of blood, thus avoid the formation of thrombosis in indwelling flexible pipe;
Alleviate nursery work: after existing remaining needle completes transfusion, normal saline washing pipe must be used, complete rear heparin sodium tube sealing, within every 6 to 8 hours, carry out siphunculus again, therefore workload is very large, this utility model eliminates above-mentioned operation nursing completely after completing transfusion, greatly simplify care program, thus alleviate nursery work;
Improve quality of medical care: thrombosis endangers very large in human body, and each medical personnel understand, when using traditional remaining needle, when carrying out the care program of siphunculus, can a large amount of thrombosis be poured in the blood vessel of human body, produce very serious potential risk.And acute vascular class disease can be produced, there is red and swollen pain in the injection site as patient, so the pot life of pertinent regulations remaining needle is 72 hours, and this utility model has the function of preventing thrombosis, therefore can quality of medical care be improved, avoid when patient is cured, the injury brought;
Reduce medical treatment cost: well-known, existing remaining needle in use, need the expense of spending washing pipe liquid, the expense of tube-sealing solution and the expense of labor of nursing, these expenses are well beyond the price of remaining needle itself, and this utility model eliminates above-mentioned expense, according to statistics, this utility model can reduce the over half of remaining needle cost of use.
