A long time ago I wrote about the popular science of saline, whether it is used as a medicine or an ordinary commodity, their composition is 0.9% sodium chloride, which is the same as the concentration of human body fluids.
Of course, there are also some hypertonic brines that contain higher sodium chloride components, such as 2.2%, 3%, 7%, 14% and so on.
But in most cases, 0.9% sodium chloride is sufficient.
In fact, Tuanzi has always had the habit of using normal saline, including myself, beijing smog and dust is relatively large, so we are habitually going home to use normal saline to wash the nose after washing our faces.
This time, I chose the cost-effective and "well-known" Internet celebrity products on the market to do the evaluation.
Let's take a big group photo first
From the left, the new version of Little Dolphin, the old version of Little Dolphin, BEGGI, Kefu, Hays Henoch, Skin Bud, and the photogenic Vader Medical.
The following text
Too long not to look at the version
Hypertonic saline was selected for Haishi Hainuo
Isotonic saline is selected from BEGGI or other 3-4 star products
The following detailed version
Little dolphins
The little dolphin is divided into new and old versions, the new version is a nipple mouth, the spray is relatively delicate, but the spray is fierce, and the naked eye can see the water droplets splashing, and the number of times the ball is choked when used, but it is within the acceptable range.
The price-performance ratio is relatively low in all salt water, buy a bottle of 40 yuan at the time of the big promotion.
Old version of the little dolphin
It is the normal saline with the largest number of slots in all brine.
This is the most accepted after the use of the dumplings, there is a strong sense of resistance, the above GIF show is the last two sprays (later can not be pressed out), the naked eye visible spray is a water column type, the degree of choking is high, and later became the tuan mom herself to use (with the principle of not waste)
BEGGI
Tuan Mom bought this brine is completely randomly selected, and later after buying it, I learned that it was recommended by the famous "net red mother" rice cake mother, although I don't like to follow the trend, but the random selection of this brine gave me a surprise.
First of all, the dumplings are very fond of spraying themselves, and the strength of other salt water cannot be moved, but this is the only one that can spray his nose with his strength; secondly, the spray is relatively delicate, similar to the water column type, but because of the small amount, the degree of choking is not high.
However, the disadvantage of BEGGI is that it is inconvenient to carry around, and the lid of the spray mouth is easy to fall off.
Kefu
Cost-effective, but the spray is relatively less delicate, and when spraying the nose, there are water droplets that can be seen with the naked eye, but not every time.
Hayesh Heino
It is the only hypertonic brine in these salt waters, and it is also a brine that Tuan Ma personally loves very much.
The effect of nasal congestion during the cold period is better than that of isotonic.
According to some data, 2.3% hypertonic sea saline is extremely beneficial for patients with chronic rhinitis, and blood circulation in the nasal cavity and sinuses is significantly accelerated.
For dumplings with rhinitis, I would prefer to use 2.2% hypertonic saline.
Cost-effective, spray fineness is higher, nasal choking degree is low.
Vader Medical
The cost performance is not high, the big promotion is relatively cost-effective, the spray is relatively delicate, but there are also water droplets splashing out, within the acceptable range.
Say at the end
Choose physiological saline as far as possible to choose a medical device quasi-word products, after all, salt water belongs to the instrument class, isotonic can be used for a long time, because its osmotic pressure is the same as the normal human body blood, tissue fluid, you use isotonic is equivalent to the degree of washing face and brushing teeth, and hypertonic to help improve the environment in the nasal cavity, the effect of rhinitis in a short period of time is stronger than isotonic, but try not to choose more than 3% hypertonic saline.
