The utility model content
This utility model is at a kind of pair of safety indwelling needle of above not enough invention, promptly solved traditional remaining needle and the potential safety hazard that scalp acupuncture landing or jointing come off can occur when operation, protected medical personnel's safety simultaneously again.
The technical scheme in the invention for solving the technical problem is:
Two safety indwelling needles comprise: sheath, indwelling flexible pipe, rivet, indwelling flexible pipe seat, draw point, draw point seat, anti-overflow plug, stainless steel protection folder, connection tube, flow-stopping clip, the anti-adverse current Y formula three way cock of malleation.
Traditional three way cock has been replaced in the anti-adverse current Y formula three way cock's of malleation application, has solved general the remaining needle landing of excuse sword-shaped needle or infusion connector in the infusion process patient that the causes serious consequence because of the death of losing blood that comes off; It is characterized in that the anti-adverse current Y formula three way cock of malleation has two kinds of different functions of positive-pressure function and anti-adverse current function simultaneously: wherein the anti-adverse current Y formula three way cock's of malleation structure has shell, base, piston, large sealing packing ring, small sealing ring, spring to constitute, and the structure of anti-adverse current comprises valve casing, baffle plate, silica gel plug.
Described pair of safety indwelling needle is characterized in that positive pressure connector is closed state under the situation that no any connector is attached thereto, and keeps aseptic condition.
Described pair of safety indwelling needle is characterized in that the principle of positive pressure connector internal structure in use produces positive-pressure function, continues to produce a malleation when taking out external article such as syringe, can prevent that blood from refluxing and the obstruction remaining needle.
Described pair of safety indwelling needle is characterized in that anti-adverse current functional connector is in a complete airtight state under normal condition, prevented backflowing of blood effectively.
Described pair of safety indwelling needle is characterized in that the silica gel plug of anti-adverse current function inside comprises two kinds of structures, and a kind of is the silicon rubber cup structure, and another kind is the silica gel chip architecture.
Described pair of safety indwelling needle is characterized in that silica gel plug can use the silica gel plug of silicon rubber cup structure, also can use the silica gel plug of silica gel chip architecture.
Described pair of safety indwelling needle; it is characterized in that loading onto on the draw point stainless steel protection folder; the stainless steel protection folder is in the draw point bottom and keeps somewhere airtight combination of flexible pipe seat; after the withdraw of the needle; the protection mounting board is lived the side opening on the draw point; the protection mounting board is lived the draw point side opening, it is taken out of keep somewhere the flexible pipe seat, and its draw point point is protected fully.
Described novel pair of safety indwelling needle; it is characterized in that stainless steel protection is installed in the draw point bottom, the stainless steel protection folder is in the draw point bottom and keeps somewhere airtight combination of flexible pipe seat, extracts draw point after puncture finishes; the draw point side opening is through overprotection folder place, and being stuck protects its draw point point.
