Description

It can be avoided the PICC conduit merging frame of misplacement

Technical field

The utility model relates to medical auxiliary apparatus technical fields, and in particular to a kind of to use when being placed in PICC conduit It can be avoided the PICC conduit merging frame of misplacement.

Background technique

Through peripherally inserted central catheter (PICC) be it is a kind of from PeV import and end be located at central vein Deep venouspuncture technology is suitable for medium-term and long-term venous transfusion, chemotherapy of tumors, parenteral nutrition, gerontal patient's infusion, provides for patient In, long-term infusion, therefore PICC conduit by Preserving time in patient's body, it usually needs 7 days to 1 year.It is to face The venous transfusion tool that must use when patient is using chemotherapeutics and dripping of irritant drugs on bed.Whether the merging of PICC conduit is suitable Whether benefit, catheter tip reach superior vena cava, determine whether PICC conduit being capable of long-term normal use.

PICC conduit is placed in from the veins of upper extremity of patient mostly, and the tip of PICC conduit is located at the epicoele of patient after merging After vein, and the veins of upper extremity of human body can finally migrate as axillary vein-subclavian vein, subclavian vein and jugular vein converge As superior vena cava, when the meet of subclavian vein, jugular vein and superior vena cava forms junctions, and PICC conduit is placed in Conduit can be made to enter jugular vein due to the angle change of patient's subclavian vein and jugular vein, rather than it is expected that epicoele it is quiet Arteries and veins, PICC catheter tip as misplacement not in superior vena cava, needs to dept. of radiology or conduit room to be adjusted under ray Pipe, catheter tip is finally sent to superior vena cava, increase many difficulty to clinical position, and it is different that PICC conduit once occurs Position, also brings unnecessary radiohazard to patient and medical worker.

PICC misplacement is that PICC sets one of complication common in pipe, and incidence is high, brings to patient sizable Pain also brings very big work difficulty to health care workers, therefore, the incidence of PICC misplacement how is reduced, to doctor For nurse author or a problem.
