A medical oncology perfusion chemotherapy dispensing device

technical field

The invention relates to the technical field of medical oncology appliances, in particular to a medical oncology perfusion chemotherapy dispensing device.

Background technique

Arterial infusion chemotherapy has the characteristics of no surgery, less trauma, quick recovery and good effect. Arterial infusion chemotherapy can combine several of the most effective anticancer drugs, find the feeding artery of the tumor through catheter technology, and inject anticancer drugs and embolic agents directly into the tumor tissue. This therapy has two main advantages: on the one hand, the high concentration of the drug is directly applied to the local area, exerting the greatest anti-tumor effect, with little systemic side effects, so that most patients can receive treatment; on the other hand, the tumor The blood vessels are blocked, causing the tumor to lose its blood supply and starve to death. Guo Yuesheng, an expert in comprehensive tumor therapy, believes that this technology is especially suitable for those malignant tumors of the liver, lung, stomach, kidney, pelvis, bone and soft tissue who have lost the opportunity for surgery or are inoperable.

Chemotherapy drugs are a kind of drugs for the treatment of tumors. Because most of the chemotherapeutic drugs are cytotoxic drugs, these drugs can act on different links of tumor cell growth and reproduction to inhibit or kill tumor cells. However, due to the toxicity of chemotherapeutic drugs, they also affect the normal cells of medical staff. During the preparation and use of chemotherapeutic drugs, particles invisible to the naked eye will often escape due to improper operation, forming aerosols containing toxic particles in the air or Aerosols, drugs enter the human body through the respiratory tract or skin and cause physical effects on medical staff.

Before the existing infusion chemotherapy, several anticancer drugs need to be mixed together by stirring. During the preparation process, the drugs will have a certain reaction when they come into contact with the air, which will make the dispensing effect not good, and will lead to viruses and particles in the outside air. It is injected into the human body through a syringe, and the chemotherapeutic drugs inevitably escape during the stirring process, and the chemotherapeutic drugs enter the human body through the respiratory tract or the skin, thereby causing physical damage to the medical staff.
