Description
Technical field
The utility model belongs to clinical treatment instrument, and in particular to a kind of antithrombotic two-chamber PICC conduit.
Background technique
Through Peripherally inserted central catheter (Peripherally Inserted Central Catheter), referred to as
PICC conduit is using periphery venipuncture of the conduit from arm, and the through big vein close to heart of conduit avoids drug and hand
The direct contact of arm vein can dilute rapidly drug in addition the blood flow velocity of big vein is very fast, prevent drug to the thorn of blood vessel
Swash, is that clinically used venous channel sets pipe selection, is suitable for carrying out medium to long term infusion.Especially some spies
Different drug is such as: the liquid or medicine of chemotherapeutics, corrosivity or dripping of irritant drugs, parenteral alimentation, pH value less than 5 or greater than 9
Object and osmotic pressure are more than that the liquid of 600mOsm/L or drug require to be administered by central venous catheter, and PICC is need to be long-term defeated
The patient and chemotherapy patients of liquid provide the vein treatment channel an of safety.
However, chronically there are still some complication being difficult to avoid that for deep venouspuncture.Conduit correlation thrombus refers to conduit
The formation of outer wall or pipe inner wall blood clot is one of most common complication after deep venouspuncture.Although in order to reduce thrombus
Optimization has been carried out in the incidence of complication, the material and technique of PICC conduit, the deep vein catheter clinically used at present
There are still some defects: (1) long-term intravenous built-in pipe in design, and formation thrombus probability is high in catheter lumen, and current conduit is set
Meter end nozzle is directly directly communicated with lumen of vessels, no anti-reflux flap valve, inevitably results in blood back flow in treatment interphase
To PICC lumen, forms thrombus and cause that unsmooth or even plugging is administered.(2) deep vein catheter of clinical application at present is mostly single-chamber
Design, no stand-by channel, once plugging conduit, that is, ineffective, it is forced tube drawing, treatment is caused to be delayed or interrupt.(3) document report
Road is more than that lateral thrombus on the outside of tube wall can be observed in 2 weeks 90% or more vein built-in pipes, and often further climing to distal end of catheter
Prolong, form Endovascular and float thrombus, dramatically increases limb swelling, thrombus breaks loose causes the risks such as pulmonary embolism；(4) clinic is answered at present
It is mostly to be administered through end stomidium with deep vein catheter, no side opening design causes to such attached tube wall thrombus without timely and effectively doing
Pre-channel.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is that proposing a kind of antithrombotic two-chamber PICC conduit,
When using two-chamber PICC conduit, contact can be carried out by the outer thrombus of tube wall caused by the opposed pipe of medicine outlet hole of outer cavities conduit pipe
Anticoagulant and thrombolytic drug therapy leads to the Deep vain thrombosis spread along conduit and the wind to fall off to reduce and set pipe for a long time
Danger；Positive pressure flap valve can prevent blood reflux from entering in lumen, reduce the generation of conduit plugging, improve the long-term patency rates of lumen；And
And outer cavities conduit pipe can be treated in the case where lumen catheter is blocked as ancillary drug access, and unintended tube drawing is reduced
Etc. unnecessary trouble.
To achieve the above object, the technical scheme adopted by the utility model is
A kind of antithrombotic two-chamber PICC conduit, two-chamber PICC conduit include lumen catheter and outer cavities conduit pipe, it is described in
Cavities conduit pipe is located at exocoel catheter interior and outer cavities conduit pipe both ends are fixedly connected with lumen catheter side wall；
The lumen catheter front end is equipped with positive pressure flap valve, and the positive pressure flap valve includes two valve blocks, two valve block front end patches
It is combined, tail end is open-shaped；The lumen catheter tail end is equipped with multiple first into medicine connector, and described first into medicine joint
It is equipped with the first flow-stop valve；
The exocoel catheter proximal end side wall has been evenly arranged multiple medicine outlet holes, and the exocoel tail end of conduit is equipped with multiple second
Into medicine connector, one of them second into medicine connector is anticoagulation connector, and described second is equipped with the second flow-stop valve into medicine joint；
It is set on the outer cavities conduit pipe there are two developing line, a developing line is located at exocoel catheter proximal end, another developing line is located at exocoel
Among conduit.
Further, the positive pressure flap valve is in closed state in its natural state, it is in open state when circulating drug；
When drug is delivered at the positive pressure flap valve, under the pressure of drug, positive pressure flap valve automatic opening, and blood will not be living from positive pressure
Valve front end flows into the conduit.
Further, exocoel catheter proximal end 5mm-10mm is stretched out in the lumen catheter front end；Lumen catheter front end is stretched out
Position install positive pressure flap valve.
Further, the medicine outlet hole has multiple, and multiple medicine outlet holes are in the length in the region that outer cavities conduit pipe side wall is formed
Degree is 4.5cm-5.5cm；The sufficient length of drug bore region ensure that the logical fluency of outer cavities conduit pipe Chinese medicine logistics.
Further, two developing lines are located at the two sides in the region of medicine outlet hole.
Further, the outer cavities conduit pipe and lumen catheter fixed connection place are in rounding off；The conduit is reduced to body
The injury of body bring.
The beneficial effects of the utility model are:
(1) when using the PICC conduit, it can carry out setting the catheter maintenance during pipe by outer cavities conduit pipe, from outer cavities conduit pipe
The anticoagulation joint of tail end imports anticoagulant or thrombolytic drug, multiple medicine outlet holes through exocoel duct wall to tube wall outside
Thrombus carries out that contact is anticoagulant and thrombolytic drug therapy, to reduce caused by setting pipe for a long time along the deep vein thrombosis shape of conduit sprawling
At and the risk that falls off；
(2) the first of lumen catheter works as lumen catheter into the first mutually indepedent into medicine connector of medicine connector and outer cavities conduit pipe
When there is blocking the case where not being available, outer cavities conduit pipe, which can be used as spare conduit, to be continued logical medicine and carries out successive treatment, reduce because
Catheter blockage, which forces patient to replace conduit, leads to repeatedly the pain of puncture and intubation, reduces treatment cost；
(3) the positive pressure flap valve of lumen catheter front end is closed in its natural state, open when being administered through lumen catheter, is being administered
Automatic closure is formed while reaching logical pharmic function prevented also from blood reflux to lumen catheter inside again after finishing
Thrombus substantially prolongs the indwelling catheter time of the conduit；
(4) by X-ray position two developing lines that outer cavities conduit pipe is equipped with can external cavities conduit pipe side wall drug porose area
Domain is positioned, and in the case where thrombus occurs, can set the position of pipe according to development positioning fine tuning, by drug bore region adjust to
Thrombi carries out anticoagulant and thrombolytic drug treatment, provides convenience for thrombolysis process.
