An auxiliary drug dispensing device for local esophageal thermochemotherapy in oncology department

Abstract

The invention relates to an auxiliary drug dispensing device for esophageal local thermotherapy used in oncology department, which includes a cabinet, a chemotherapy device, a thermotherapy instrument, a chemotherapy cover and a drug dispensing device. Drain bottle, the catheter is equipped with a number of thermotherapy devices for storing thermotherapy liquid, and the catheters on both sides of each thermotherapy device are equipped with sealed air bags, which are used to contact the inner wall of the esophagus after being filled with nitrogen gas, and in a section of the esophagus A treatment area is formed inside, and the drug dispensing device grinds the medicine evenly and delivers it to the liquid medicine bottle and the chemotherapy cover through the first delivery tube and the second delivery tube respectively. The device of the invention utilizes the difference in temperature tolerance between normal tissues and tumor cells to achieve the therapeutic purpose of shrinking or eliminating tumors without damaging normal tissues, and at the same time can effectively grind drugs and efficiently and accurately deliver them to lesion sites.

Description

technical field [0001] The invention relates to the technical field of medical devices for oncology, in particular to an auxiliary dispensing device for esophagus local thermochemotherapy for oncology. Background technique [0002] Oncology is a secondary discipline responsible for the treatment of various types of tumors in clinical medicine. The commonly used treatment methods are surgery, radiotherapy and chemotherapy. Among them, chemotherapy is one of the most effective methods for the treatment of esophageal cancer, and thermochemotherapy refers to the combination of chemotherapy and heat. It is a new therapy that combines chemotherapy and application to treat tumors. It usually needs to grind the drug, and then use physical energy to heat the chemotherapeutic drug with good thermal effect, so that the temperature of the tissue near the tumor rises to 41.5 ℃, and the tumor temperature reaches 43-48 ℃. The difference in temperature tolerance between tissues and tumor ce...
