Linquan ** Hospital
In winter, when the weather is cold, many people hold hot water bottles in their hands to warm their hands and relieve the cold quilts. Recently, Xiao Wang woke up and found that there were inexplicable red spots or blisters on his legs, and it hurt very much if he didn't touch it, and it was faintly hotRecently, Ms. Liu's thighs also suddenly had countless large and small blisters, red and swollen, and some of them peeled off, and all because of the ordinary hot water bottle!
The hot water bottle suddenly burst, and the woman's thigh was burned for the second degree
Recently, 32-year-old Ms. Liu (pseudonym) put a hot water bottle filled with boiling water into the quilt before going to bed at night. Unbeknownst to her, just as she got into the bed and put the hot water bottle on her lap, the hot water bottle burst without warning!The boiling water was all sprayed on her legs, and she screamed in pain.
Ms. Liu, accompanied by her family, rushed to the emergency department of Beilun District People's Hospital in Ningbo, Zhejiang Province (Beilun Branch of the First Hospital of Zhejiang University) for treatment. Dr. Li Baojun, who received the consultation, found that Ms. Liu's two inner thighs were red and swollen, with several large and small blisters, part of the epidermis was peeled off, and there was oozing fluid around it, which was a superficial second-degree to deep second-degree burn on both thighs.
What is puzzling is that the hot water bottle that is usually used well, how can I say**just**?
It turns out that the hot water bottle** is because the heating wire or electrode inside the hot water bottle will rust, and when the rust enters the liquid, it will cause the liquid resistance to decrease, the heating power will increase, and then the temperature will rise. At this time, if the temperature controller fails, the liquid will be vaporized after exceeding a certain temperature**. In addition, because the liquid itself will be charged when heating, and there is no overvoltage protection device, the user of this electric hot water bottle will not only be burned when ** or leakage, but also is likely to be electrocuted. When the hot water bottle was first bought, it would automatically power off due to its good performance. With the increase of use time, the hot water bottle parts are aging, and the automatic power-off function fails, but it will be flatulent, if you do not unplug the power supply in time, I am afraid that it will be **.
In addition, hot water bottles also have the following safety hazards:
Burns at low temperatures
I only know that high temperature scalds, low temperature can also burn people?Cryogenic burns are burns caused by prolonged exposure to low-heat objects that are higher than body temperature. For example, hot water bottles, hand warmers and other heating artifacts, many people hold them for a whole night, your ** is in a state of high temperature for a long time, and it is easy to cause burns if you are not careful!
Charged hot water is very likely to cause "low-temperature burns" for a long time, and long-term contact with low-temperature heat sources will gradually develop into burns in the deep dermis and subcutaneous tissues. The low-temperature scald wound appears red, swollen, blistered, peeling or whitish on the **, and the wound is deep and severe, and even causes deep tissue necrosis, if it is not treated properly, it will ulcerate in severe cases, and it will not heal for a long time.
Dermatitis
If the electric hot water bottle is used for too long, it is also easy to induce dermatitis. This is because using the electric hot water bottle for a long time will cause too much water loss in the **, which will become dry and itchy, leading to allergies and dermatitis. Especially the elderly or dry ** people should pay special attention. Therefore, you should also pay attention to hydration when using electric hot water bottles.
So, we need to pay attention to the following:
1.When using rechargeable hot water bottles, be sure to buy products produced by regular manufacturers at regular merchants, and the products must have national 3C certification and product certification, and the fabrics should be made of fireproof fabrics.
2.Pay attention to the service life of the hot water bottle, and resolutely do not use the hot water bottle beyond the expiration date.
3.Avoid connecting the power supply for a long time, and the power supply will not be unplugged for a long time, which is prone to electric shock. And the charging time should not be too long, and the charging should be terminated within 2 minutes after the indicator light goes out to prolong its service life.
