使用期限

Duration of use

从人类生理学的观点来看,鼻粘膜中的血液循环非常强,并且鼻腔中的通道非常曲折。鼻毛构成过滤“屏障”。当空气被吸入鼻孔时,气流会在曲折的通道中形成涡流,从而加热被吸入鼻腔的气流。一些测试表明,当零下7°C的冷空气通过鼻腔吸入肺部时,气流已被加热到28.8°C,非常接近人体温度。如果长时间戴口罩,鼻粘膜会变得脆弱,鼻腔原有的生理功能也会丧失,因此不能长时间戴口罩。口罩只能在特殊环境下使用,例如在有很多人的地方且没有空气流通的地方。当然,在野外行走时,为了抵御风沙和寒冷,或在空气污染的环境中活动,您需要戴上口罩,但时间不要太长。另外,在流感季节,要去可能有大量病原体的公共场所,还应戴口罩。戴口罩只是预防呼吸道传染病的方法之一。最重要的是保持良好的生活习惯。

From the point of view of human physiology, blood circulation in the nasal mucosa is very strong, and the channels in the nasal cavity are very tortuous. The nose hairs constitute a filtering “barrier”. When air is sucked into the nostrils, the airflow forms a vortex in the tortuous channel, which heats the airflow sucked into the nasal cavity. Some tests have shown that when cold air at minus 7°C is drawn into the lungs through the nasal cavity, the airflow has been heated to 28.8°C, which is very close to the temperature of the human body. If you wear a mask for a long time, the nasal mucosa will become fragile and the original physiological function of the nasal cavity will be lost, so you cannot wear a mask for a long time. Masks can only be worn in special environments, such as places with many people and no air circulation. Of course, walking in the wild, in order to resist wind and sand and cold, or activities in an environment with air pollution, you need to wear a mask, but the time should not be too long. In addition, in the flu season, go to public places where there may be a large number of pathogens, you should also wear a mask. Wearing a mask is only one of the ways to prevent respiratory infectious diseases. The most important thing is to maintain good living habits.

清洁与保养

Cleaning and maintenance

面罩的外层经常在外界空气中积聚大量灰尘,细菌和其他污垢,而内层则阻止呼出的细菌和唾液。 因此,这两个侧面不能交替使用,否则被外层污染的污垢将直接附着在人体上,当被吸入时,它成为感染源。 当不戴口罩时,应将其折叠成一个干净的信封,并且将靠近鼻子和鼻子的一侧向内折叠。 请勿将其塞入口袋或挂在脖子上。

The outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air, and the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt contaminated by the outer layer will be directly attached When inhaled into the body, it becomes a source of infection. When the mask is not worn, it should be folded into a clean envelope, and the side that is close to the nose and nose should be folded inwards. Do not stuff it into your pocket or hang it around your neck.

日常使用口罩必须妥善处理

Daily use of masks must be properly handled

如果口罩被呼出的热量或唾液弄湿,则其阻挡细菌的作用将大大降低。 因此,最好准备更多的口罩以进行更换。 您应该每天更换并清洗一次。 洗涤时,应用开水烫5分钟。

If the mask is wetted by exhaled heat or saliva, its effect of blocking germs will be greatly reduced. Therefore, it is best to prepare a few more masks for replacement. You should change and wash them once a day. When washing, it should be scalded with boiling water for 5 minutes.

口罩应每天清洁和消毒。 纱布口罩和空气过滤器口罩均可通过加热进行消毒。 具体方法是:

Masks should be cleaned and disinfected every day. Both gauze masks and air filter masks can be sterilized by heating. The specific approach is:

1.清洁。 首先,用温水和肥皂轻轻擦拭纱布面膜。 可以用蘸有清洁剂的软刷轻轻刷洗碗形面膜,然后用水冲洗。 请注意不要用力摩擦,因为如果纱布的经纬间隙太大,将会失去防滴效果。

1. Cleaning. First, gently rub the gauze mask with warm water and soap. The bowl-shaped mask can be gently brushed with a soft brush dipped in detergent, and then washed with water. Please be careful not to rub hard, because if the warp and weft gap of the gauze is too large, it will lose the effect of preventing droplets.

2.消毒。 将清洁过的面膜放在2%的过氧乙酸溶液中30分钟,或在沸水中煮沸20分钟,或在蒸锅中蒸15分钟,然后干燥使用。 此方法适用于纱布口罩和碗罩。

2. Disinfection. Place the cleaned mask in a 2% peracetic acid solution for 30 minutes or boil in boiling water for 20 minutes or steam in a steamer for 15 minutes, and then dry it for use. This method is suitable for gauze masks and bowl masks.

3.检查。 再次使用前,应仔细检查口罩和口罩是否完好无损。 对于纱布口罩和口罩,可以采用透光检查方法,即在灯前看一下是否有明显的光斑,中间部分和边缘部分是否透明,速率是否一致? 如有疑问,请更换新的。 在任何情况下,面罩和口罩通常在清洗3至7次后会更新,并且质量特别好的口罩可以清洗10次。 活性炭吸附口罩应注意定期更换活性炭夹层。 如果活性炭中间层不可更换,则将在7到14天后更换。 此面罩无法清洗然后再使用。

3. Check. Before using it again, you should carefully check whether the mask and mask are still intact. For gauze masks and masks, you can take a light transmission inspection method, that is, take a look in front of the lamp to see if there are obvious light spots, the middle part and the edge part are transparent Is the rate consistent? If in doubt, replace it with a new one. In any case, face masks and masks are generally updated after 3 to 7 cleanings, and masks of particularly good quality can be cleaned 10 times. Activated carbon adsorption masks should pay attention to regularly replace the activated carbon interlayer. If the activated carbon interlayer is not replaceable, it will be replaced after 7 to 14 days. This mask cannot be cleaned and then reused.

正确处理

Proper handling

日常使用口罩应妥善处理。 患者使用或在护理期间使用的口罩,应在处理之前放在患者室的带衬里的容器中。

Daily use of masks should be properly handled. Masks used by patients or used during care should be placed in lined containers in the patient room before processing.
