摘　　要：气垫属于软质麻醉面罩的重要组成部分,直接与病人面部皮肤接触,其材质性能的好坏直接决定着麻醉面罩的使用效果。聚氯乙烯(PVC)具有较好的力学性能、耐腐蚀性能,还因其价格适宜,在工业、医学等领域应用广泛。通过实验方法,制备一种软质麻醉面罩气垫PVC抗菌材料,因其具有较强的抗菌性能,并具备一定的力学性能和柔韧性,能够实现较好的贴合效果,密封效果和佩戴舒适度都有所增加。结果表明:当抗菌剂添加量不断增加时,材料的抗菌性能不断提高,且当抗菌剂添加量为1.5 g时,材料的抗菌率为96.15%,此时材料的力学性能最优;对制备好的软质麻醉面罩气垫PVC抗菌材料进行热力学分析,发现添加抗菌剂的材料比不添加抗菌剂的材料具有更好的柔韧性。The air cushion is an important part of the soft anesthesia mask.It is in direct contact with the patient’s facial skin.The quality of its material and performance directly determines the effect of the anesthesia mask.Polyvinyl chloride(PVC)has good mechanical properties,corrosion resistance.It is also widely used in industries,medicine and other fields due to its affordable price Through the experimental method,a PVC soft anesthesia mask cushion material withantibacterial propertywas prepared.The material has strong antibacterial properties,certain mechanical properties and flexibility,can achieve good fitting effect,and the sealing and wearing comfort are increased.The experimental results showed that when the added amount of antibacterial agent increased,the antibacterial performance of the material continuedto increase,and when the added amount of antibacterial agent was 1.5 g,the antibacterial rate of the material was 96.15%.At this time,the mechanical properties of the material were the best.When thermodynamic analysis was applied to prepared PVCsoft anesthesia mask cushion material,it was found that the material with added antibacterial agents exhibited better flexibility compared to the material without antibacterial agents.
