Convenient and accurate control drug delivery device for medical oncology nursing
Technical Field
The invention relates to the technical field of medical auxiliary equipment, in particular to a convenient and accurate-control drug delivery device for medical oncology nursing.
Background
According to the biological characteristics of tumors and the difference of harmfulness to organisms, tumors can be divided into two major types, namely benign tumors and malignant tumors. The former has slow growth, clear boundary with surrounding tissues, no transfer and little harm to human health. The latter grows rapidly, can be transferred to other parts of the body, can also produce harmful substances, damage normal organ structures, cause organism dysfunction and threaten life.
The existing drug therapy aiming at most medical oncology adopts a drug taking method, but the drug taking period is longer, and the drug absorption is carried out through a digestive system instead of directly taking the drug to the internal medical tumor affected part, so that the effect is slow, the control effect is not obvious, long-time therapy is needed, and the pain and the burden of a patient are increased. In addition, some medical oncology nursing adopts an intervention type drug delivery method, therapeutic agents need to be slowly injected to a tumor lesion part, and medical workers need to stably hold an injector with hands in the process, so that the labor intensity is high, the stability of holding by the medical workers is not high due to long injection time, the treatment effect is influenced, and the dosage of the drugs cannot be adjusted according to the actual treatment condition. Therefore, we propose a convenient and accurately controlled administration device for medical oncology nursing to solve the above problems.
