Dilute chemotherapeutics can be rushed rapidly, prevent stimulation of the drug to blood vessel.Therefore can effective protection veins of upper extremity, reduce phlebitis
Generation, mitigate the pain of patient, improve the quality of life of patient.
It is usually at present transparent dressing covering treatment for the puncture orifice through periphery venipuncture central vein catheter, it is remaining
One segment body outer tube, which is folded into U-shaped, makes calparine cap towards puncture orifice direction.External pipe is usually to be fixed with medical adhesive tape.Because of chemotherapy
The chemotherapy of patients period is mostly 1 year or so, if being that can maintain completely through getting well for periphery venipuncture central vein catheter maintenance
Arrive end of chemotherapy.Transparent dressing is usually a week with changing once.The problem of patient commonly encounters in real life be,
Medical adhesive tape viscosity can not be continued for, and external tube capacity is easy to fall off to rip puncture orifice, and patient and Relatives of Patients Hospitalized can not continue to close
Note sets the puncture orifice situation of pipe, and many times puncture orifice, transparent dressing rupture, leakage of body fluids oneself can not know in time.Cause
The self-healing ability of human body slightly tears to go out body with liquorrhea and can tear that breach is larger, and body fluid is big once encountering with self-healing
Amount leakage, and patient itself does not feel the abnormal conditions such as pain just and can not seek in time that doctor helps to handle, serious shadow
Ring health and therapeutic effect, serious or even life-threatening.
