In order to solve the problem of environmental contamination of drugs, cross infection among various drugs, cross drug resistance, and the harm of drugs, antibiotics and other drugs to technicians, it is particularly important to design and purify air conditioning and ventilation systems in a clean environment.
Taking a hospital intravenous distribution center as an example, this paper expounds the design of clean air conditioning and ventilation system in the Department. The design area includes common drugs and TPN configuration rooms and clean auxiliary rooms, antibiotics and toxic drug dispensing rooms, tumor drug dispensing rooms and clean auxiliary rooms.
所谓静脉药物配置中心（Pharmacy Intravenous Admixture Services，缩写：PIVAS）是指在符合标准、依据药物特性设计的操作环境下，经药技师严格按相关标准进行全营养药物、抗生素等静脉药物的配置，为临床提供服务的机构。简而言之，即集中配置静脉药液的场所。
The so-called PIVAS (Pharmacy Intravenous Admixture Services, abbreviation: PIVAS) is defined in accordance with international standards, based on the characteristics of the drug design operation environment, the pharmacy technicians in strict accordance with the relevant standards for drug drugs and antibiotics intravenous total nutrient allocation and provide services for clinical institutions. In short, it is the place where the vene liquid is concentrated.
Main technical indexes of clean room
One is more, the washing room is one hundred thousand grade, the temperature is 18 to 26, and the relative humidity is 40% ~ 65%.
Two, more commonly, between the general drug and TPN configuration, between the antibiotics and the toxic drug configuration, the level of purification is 10000, the temperature is between 18 and 26 degrees, and the relative humidity is 40% to 65%.
The laminar flow table is a hundred grade.
It is divided into two sets of air conditioning systems
Common drug and TPN configuration and its clean auxiliary room;
The allocation of antibiotics and toxic drugs, the allocation of tumor drugs and the clean auxiliary room.
The cleaning air conditioning system between the common drugs and the TPN configuration and the clean auxiliary room uses a return air system to send and lower the air.
The configuration between tumor drug and clean auxiliary room air purification using the new air system of antibiotics and drug toxicity, configuration, on the way to send.
The ordinary medicine and the TPN configuration set up a hundred level work table and lay on the wall.
Although the worktable is a local layer of laminar flow, there will be turbulence in the room once the staff are in the room. Therefore, it is particularly important to properly arrange the position of the high efficiency air vent and to organize the direction of the air flow reasonably. In this project, a high efficient air vent is arranged at the top of each worktable, and the side wall of the side wall is arranged back. There are 5 A2 II biosafety cabinets between antibiotics and toxic drug configurations, and 2 sets of B2 II biosafety cabinets arranged by the wall.
