济南隔离服:降低医用隔离服成本需要怎样制作隔离服?

每天跟血液、病毒、细菌打交道的“白衣天使”正时刻处于高风险之中,他们保卫着病人的健康,又是谁来保卫他们的健康?治疗新冠病毒肺炎重症患者,需要消耗10套防护服吗?单件防护服成本接近三四百元吗?当前疫情防控形势下,身着防护服的“白衣天使”形象不断刷屏,然而防护服也成为中国防疫急需物资之一。

The "angels in white" who deal with blood, viruses and bacteria every day are at high risk. They are protecting the health of patients. Who is going to protect their health? Does the treatment of severe patients with new coronavirus pneumonia need to consume 10 sets of protective clothing a day? Is the cost of a single protective suit close to 340 yuan? Under the current situation of epidemic prevention and control, the image of "angel in white" wearing protective clothing is constantly brushing the screen. However, protective clothing has also become one of the urgently needed materials for epidemic prevention in China.
拒水、拒血液、拒酒精+抗静电
Water repellent, blood repellent, alcohol repellent + antistatic
防护服不仅要排湿透气、穿着自如,还要让医护人员免受诊疗过程中病毒、细菌等各种污染物的感染,抵挡住水液、酒精、油渍侵入,而且要有效抗静电,甚至防止灰尘进入。
The protective clothing shall not only be moisture and air permeable, and be worn freely, but also prevent the medical staff from being infected by various pollutants such as viruses and bacteria in the process of diagnosis and treatment, resist the invasion of water, alcohol and oil stains, and effectively resist the static electricity, even prevent the dust from entering.
由于采用微纳米级别的医卫防护非织造材料,防护服的基本要求就是“三拒一抗”,即拒水、拒血液、拒酒精以及抗静电。靳向煜进行科普说,这样的复合材料可以通过不同材料复合,如用聚乙烯/聚丙烯纺黏非织造布,与透气微孔薄膜或其他非织造布复合,或用水刺非织造布与透气微孔薄膜复合,或用木桨复合水刺非织造布。
Due to the use of micro nano medical nonwovens, the basic requirement of protective clothing is "three repellents and one anti-static", that is, water repellent, blood repellent, alcohol repellent and anti-static. According to Jin Xiangyu, such composite materials can be compounded by different materials, such as polyethylene / polypropylene spunbond nonwovens, air permeable microporous films or other nonwovens, spunlaced nonwovens and air permeable microporous films, or wood oars.
值得注意的是,防护服材料的几种性能有严格标准,包括防护性(密封性)、服用性、安全卫生性。其中防护性要求具有液体阻隔功能,防护服关键部位(左右前襟、左右臂及背部位置)带着抗渗水性,可耐静水压不低于1.67千帕(kPa);抗合成血液穿透性不低于2级,即合成血液以1.75千帕的压强作用于防护服上,5分钟后不得穿透;同时,防护服外侧面沾水等级不低于3级。此外,还要防微颗粒物穿透,关键部位及接缝处对非油性颗粒物的过滤效率不低于70%。
It is worth noting that there are strict standards for several properties of protective clothing materials, including protection (sealing), wearing, safety and health. Among them, the protective function is required to have liquid barrier function. The key parts of the protective clothing (left and right front, left and right arms and back positions) are water resistant, and the hydrostatic pressure resistance is not less than 1.67kpa; the penetration resistance of synthetic blood is not less than level 2, i.e. the synthetic blood acts on the protective clothing with a pressure of 1.75kpa, and shall not be penetrated after 5 minutes; at the same time, the water level on the outer side of the protective clothing is not Below level 3. In addition, it is necessary to prevent the penetration of micro particles. The filtration efficiency of key parts and joints for non oil particles shall not be less than 70%.
对于服用性要求,防护服要有足够强度和尺寸稳定性,进行拉伸试验时,断裂强力不低于45牛,断裂伸长率不低于30%;穿着舒适性方面,防护服材料具有透湿量要求。而安全卫生性则要求自身无毒,无皮肤刺激性,抗霉菌滋生。
For the wearing requirements, the protective clothing shall have sufficient strength and dimensional stability. During the tensile test, the breaking strength shall not be less than 45 n, and the elongation at break shall not be less than 30%; for the wearing comfort, the protective clothing material shall have the moisture permeability requirements. But the safety and health requires that it is non-toxic, non irritating and anti mildew.
