Description

Chemotherapy medicine injection exudation treatment instrument for cancer patient

Technical Field

The invention relates to the technical field of medical apparatus and cancer, in particular to a chemotherapy drug injection exudation treatment instrument for cancer patients.

Background

Medically, cancer refers to a malignant tumor that originates in epithelial tissue, and is the most common type of malignant tumor. Correspondingly, malignant tumors originating in mesenchymal tissue are collectively referred to as sarcomas. There are a few malignant tumors that are not named according to the above principles, such as wilms' tumor, malignant teratoma, etc. The general term "cancer" is used to generally refer to all malignant tumors. Cancer has the biological characteristics of abnormal cell differentiation and proliferation, uncontrolled growth, infiltrative property, metastatic property and the like, the occurrence of the cancer is a multi-factor and multi-step complex process which is divided into three processes of carcinogenesis, cancer promotion and evolution, the three processes are closely related to smoking, infection, occupational exposure, environmental pollution, unreasonable diet and genetic factors, the method for treating the cancer is a chemotherapy method, the chemotherapy is short for chemical drug therapy, and the purpose of treating the cancer is achieved by killing cancer cells by using a chemical therapy drug. Chemotherapy is one of the most effective means for treating cancer at present, and is also called three major treatment means of cancer together with surgery and radiotherapy. Surgery and radiotherapy belong to local treatment, are only effective on tumors at treatment sites, and are difficult to effectively treat potential metastatic lesions (cancer cells actually have metastasized but cannot be clinically detected due to the limitation of the current technical means) and cancers with clinical metastasis. Chemotherapy is a systemic treatment means, and no matter what route is adopted (oral administration, intravenous administration, body cavity administration and the like), chemotherapy drugs are distributed throughout most organs and tissues of the whole body along with blood circulation. Therefore, chemotherapy is the main treatment for some tumors prone to systemic dissemination and middle and late stage tumors that have metastasized, and the traditional methods have the following disadvantages:

1. when the chemotherapy drugs are taken orally, the chemotherapy drugs are mostly in solid tablet shapes, and patients can take more drugs when taking the chemotherapy drugs, which is not beneficial to swallowing;

2. when a patient injects chemotherapy liquid medicine, if the injection part shakes, the injector is separated from the buried needle, so that the chemotherapy medicine leaks out, the skin of the patient is injured, and the internal tissue is seriously damaged;

3. because follow same intravenous route chemotherapy medicine for a long time, perhaps patient's vein blood vessel is comparatively fragile, can appear the condition that the liquid medicine exosmoses in the injection process, the blood vessel breaks back liquid medicine and corrodes the injury to tissue even bone, and traditional machine is not convenient for in time carry out the preliminary treatment.
