Description
Technical Field
The invention relates to a medical device, in particular to a multifunctional medical biosafety cabinet.
Background
The harm of chemotherapy drugs to the human body is well known, and when the ampoule is opened or the needle is pulled out after the liquid medicine in the ampoule is extracted during the preparation process of the cytotoxic drugs, some liquid medicine which is invisible to the naked eye overflows. This allows the formation of aerosols and aerosols containing toxic particles which can be absorbed by the human body through the skin, mucous membranes and respiratory tract of the operator. There were scholars to detect yesterday's remaining metabolites of anticancer drugs from the urine of oncology caregivers. It is also shown in the relevant literature that examination of the health of caregivers shows that caregivers who contact anti-tumor drugs are more likely to experience abnormal menstruation, alopecia and rash, and caregivers are likely to cause oral ulcers and abnormal cells, even leading to abortion of nurses. With the continuous extension of the working time of the nursing staff in oncology, the incidence of some adverse reflection conditions caused by the continuous extension of the working time of the nursing staff in oncology is obviously increased. Also, antitumor drugs can operate through placental pregnancy, which can lead to spontaneous abortion or malformation in the fetus. Therefore, when the chemotherapeutic drugs are configured, the configured environment needs to be configured in a centralized way and a standard vertical laminar flow biosafety cabinet is installed. The biosafety cabinet is widely applied to various medical institutions and laboratory centers. It can effectively reduce the environmental pollution of the hospital of aerosol and ware and the injury to relevant nursing staff. Biosafety cabinets are the most basic safety protection device in the primary protective barrier in biosafety in hospitals.
In order to ensure the safety of medical staff and working environment in daily use, the medical biosafety cabinet prevents personnel injury and environmental pollution caused by pathogenic microorganism diffusion of operation, and in the normal running process, the medical staff is required to operate correctly, and the medical engineering staff is required to maintain and detect regularly, so that the maximum guarantee effect can be exerted, and the medical risk is reduced. The distance from the air inlet and the air outlet of the biological safety cabinet to the biological safety cabinet has great influence on the flow velocity, when a large amount of cytotoxic drugs are configured in clinical actual work, the air inlet of the biological safety cabinet is often blocked by articles, and the air outlet normally supplies air at the moment to cause staff to infect, so that personal safety accidents are caused. The operator takes out part of the medical waste safety cabinet in the operation process, thereby increasing the probability of external environment pollution. Therefore, the objects on the operation table are cleaned in time to reduce the concentration of the medicines in the cabinet, and the pollution links are necessary.
