  • 静脉药物配置中心的通风系统设计
    来源:http://www.sdyhrs.com 浏览: 发布日期:2019-05-15
    在静脉药物配置中心装修的过程中,通风系统的设计是十分关键的,因为这不仅关系着配配置室的空气洁净程度,还影响着空气的压差,所以装修静脉药物配置中心时,我们要对通风系统的施工多加注意!
    The design of ventilation system is very important in the process of decoration of intravenous drug allocation center, because it not only affects the air cleanliness of the allocation room, but also affects the air pressure difference. Therefore, when decorating intravenous drug allocation center, we should pay more attention to the construction of ventilation system.
    据《静脉用药集中调配质量管理规范》要求:“洁净区应当持续送入新风,并维持正压差;抗生素类、危害药品静脉用药调配的洁净区和二次更衣室之间应当呈5~10帕负压差。”
    According to the requirement of Quality Control Standard for Concentrated Intravenous Drug Dispension, fresh air should be continuously fed into the clean area and positive pressure difference should be maintained. The negative pressure difference between the clean area for intravenous drug dispensing of antibiotics and harmful drugs and the second dressing room should be 5-10 Pa.
    本项目压差(洁净区对非洁净区)设计如下:
    The pressure difference (clean area versus non-clean area) of this project is designed as follows:
    肿瘤药物配置间≥+12Pa,抗生素及毒性药物配置间≥+18Pa,二更≥+25Pa,一更≥+10Pa。
    Tumor drug allocation (>+12Pa), antibiotics and toxic drug allocation (>+18Pa), two more (>+25Pa), one more (>+10Pa).
    普通药物及肠外营养药物配置间≥+20Pa,二更≥+15Pa,一更≥+10Pa。
    The allocation of general drugs and parenteral nutrition drugs is (+20 Pa), two more (+15 Pa) and one more (+10 Pa).

    ⅡA2系列生物安全柜内空气70%循环,30%排出室外;内置风机同时用于送风和排风;工作区负压,无污物泄漏。
    II A2 series biosafety cabinet air 70% cycle, 30% discharge outdoor; built-in fan for both air supply and exhaust; working area negative pressure, no pollution leakage.
    ⅡB2系列生物安全柜内空气100%排出室外,其中70%自柜顶进风口,30%自正面操作口;内置风机仅用于送风,排风机需外接;工作区负压,无污物泄漏。
    IIB2 series biosafety cabinet exhaust 100% of the air outdoors, 70% of them from the top of the cabinet air intake, 30% from the positive operating port; built-in fan is only used for air supply, exhaust fan needs external connection; working area negative pressure, no pollution leakage.

    ,生物安全柜排风,包括5台ⅡA2安全柜的独立外置排风机和2台ⅡB2安全柜的独立外置排风机;
    Firstly, the exhaust air of biosafety cabinet includes 5 independent external exhaust fans of II A2 safety cabinet and 2 independent external exhaust fans of II B2 safety cabinet.
    第二,房间排风,抗生素及毒性药物配置间、肿瘤药物配置间及辅房共用1台房间排风柜。
    Secondly, room ventilation, antibiotics and toxic drugs allocation room, cancer drug allocation room and auxiliary room share a room ventilation cabinet.
    压差控制方案
    Differential Pressure Control Scheme
    压差控制方案为对于具有一定泄露面积的洁净室,让室内的送风量与排风量保持一定的差值,就会产生压差,当排风量大于送风量即形成负压差。
    The pressure difference control scheme is to maintain a certain difference between the air supply and the air discharge in a clean room with a certain leakage area, which will produce a pressure difference. When the air discharge is larger than the air supply, a negative pressure difference will be formed.
    设计定风量阀恒定各房间送风量,设计压力无关型阀门:电动文丘里阀调节排风量以响应状态变化,并使排风量大于送风量,以形成负压差。
    The constant air volume valve is designed to keep the air supply in each room constant, and the pressure-independent valve is designed: the electric venturi valve regulates the exhaust air volume to respond to the change of state, and makes the exhaust air volume larger than the supply air volume, so as to form a negative pressure difference.
    调节房间排风量方案
    The Scheme of Adjusting Room Exhaust Volume
    排风量的调节是根据房间压差变化,控制文丘里阀的开度来实现。当压差绝对值大于设定值时,说明排风过大,应调小风阀开度,减小排风;反之,压差绝对值小于设定值时,说明排风不足,应调大风阀开度,增大排风。
    The adjustment of exhaust air volume is realized by controlling the opening of Venturi valve according to the variation of room pressure difference. When the absolute value of the pressure difference is greater than the set value, it shows that the exhaust air should be adjusted to reduce the exhaust air, while when the absolute value of the pressure difference is less than the set value, it shows that the exhaust air is insufficient, the opening of the air valve should be increased to increase the exhaust air.
