Technical field
The present invention relates to tumor chemoradiotherapy technical fields, and in particular to a kind of oncology built-in type chemicotherapy pump.
Background technique
Radiation and chemotherapy plays fragmentation effect in Sensitive Tumor Cells, depends primarily on drug concentration and effective contact
Time, therefore try to make drug in tumor focus part high concentration, for a long time presence as much as possible, it is to improve local treatment effect
The key of fruit.The subcutaneously duplicate progress chemotherapeutics perfusion of embedded chemotherapy pump, can greatly improve local drug concentration,
To further increase the curative effect of Partial tumors.
Now traditional implanted chemotherapy pump, when injecting drug, since pump housing merging can not subcutaneously see puncture diaphragm
Position, the region of micro-judgment injection needle point insertion can only be leaned on, the pump housing made of titanium alloy can in injection needle insertion
Hear metal bump sound, but the pump housing of thermoplastic, it when puncture needle bottoms out, will not make a sound, so being not easy to judge
The depth of injection needle.
Chemotherapeutics is injected chemotherapy pump using infusion pump, sacculus duration chemotherapy pump by the implanted chemotherapy pump after burying
It is interior, tumor focus is imported via conduit, implanted chemotherapy pump does not store the effect of chemotherapeutics, for bladder cancer, uterine cancer
In equal cavitys for mucous membrane cancer, due to the effect by inner membrance juice, the concentration of chemotherapeutics can be reduced, or even with secretion
Liquid stream goes out, and reduces the concentration of its chemotherapeutics, and the time that high concentration medicine retains in tumor focus is short, does not have drug effect,
And the time that drug is contacted with endocardial wall is short, and the drug effect of chemotherapy is not achieved.
