Loss of temperature is also called hypothermia , which means that the loss of heat in the body is greater than the supply of calories, resulting in a decrease in the temperature of the core area of ​​the body and a series of symptoms such as chills, confusion, heart and lung failure, and even death.
A mountaineer who is exposed to rain, snow, strong winds, and cold for an extended period of time is prone to getting into a state of temperature loss. In the cold and windy mountains, it is cool to cool but still wears sweaty underwear. The clothing is not warm enough and it is no longer lying down. Exercise, body heat production less than heat, it is easy to lead to loss of temperature
How is temperature loss formed?
For most people: temperature, humidity, wind power, these three factors are the most common direct causes of loss of temperature in people's daily lives. As long as two factors are present in the three elements, there may be problems.
How does temperature, humidity, and wind affect the human body and cause temperature loss?
First look at the effect of temperature on the human body : When the body is surrounded by water, the speed at which heat is dissipated is 25 times faster than in static air!
Let's look at the effect of wind on the temperature of body temperature : From the cold-effect table, if the outside temperature is minus 5 degrees Celsius, when the wind reaches six to seven levels, that is, wind speed of about 50 kilometers, the temperature of the body will suddenly drop to minus 15 degrees Celsius.
If humidity and wind force act at the same time, one can imagine how fast the temperature of body temperature drops.
Core temperature changes and corresponding symptoms
Loss of temperature can lead to decreased physical coordination and judgment and may lead to more serious problems
When climbing in a cold environment, the climber must pay attention to each other's state. If your teammates become more and more silent, this may not be a good thing. Even the slightest temperature loss must be taken seriously because it shows that The patient's ability to maintain core temperature and to the edge of depletion. Without treatment, loss of temperature can easily lead to loss of consciousness and heart and lung failure.
Loss of temperature in the scientific response to the senior ALICE Weapons : To timely replenish energy, energy, including energy gel, sugar (including glucose, chocolate, starch) but also do a good job of body insulation, usually with insulation film, and sometimes also prepared for insulation carbon Wrap up the patient to ensure that it will not lose temperature again. In the process, he must also provide food for the patient. If possible, give him sugar-containing fruits, such as bananas and apple juice, and give him food.It should be emphasized that in the initial mildly degenerative and moderately degenerative stages, patients with hypothermia can also be improved by their own heat production, but if they do not pay attention in the first two stages and are severely deprived, hypothermia occurs. The patient can no longer generate heat to maintain his/her own life. At this time, if no one can help with proper treatment, it will be extremely dangerous and even lead to death of the patient.
Therefore, outdoor sports to avoid losing temperature, preparatory work must be done before doing fine. Insulation materials, food supplies and medical supplies must be adequate and in place, the drug should be prepared enough, food should be prepared at least half a meal; can take more glucose, Small or light, easy to carry chocolate
note:
Care should be taken when handling the patient because myocardial tissue is very unstable at low temperatures and external stimuli can easily cause ventricular fibrillation.
Keep the patient lying down so that there is no backflow of cold blood from the peripheral blood vessels to the heart, resulting in cardiac arrest.
Parts that have lost temperature or frostbite must not be rubbed or wiped because they can easily cause secondary damage to the injured area due to mechanical force.
Do not give alcohol to patients
Lathing is a method of cutting the workpiece on the lathe by rotating the workpiece relative to the tool. Use the rotary motion of the workpiece and the linear or curved motion of the tool to change the shape and size of the blank, and process it to meet the requirements of the drawing. Lathing is the most basic and common cutting method, and it occupies a very important position in production. Lathing is suitable for machining revolving surfaces. Most workpieces with revolving surfaces can be processed by lathing methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads, and revolving forming surfaces.
Our company has rich experience in the production of lathed parts. We can produce the parts of high-precision, the parts of medium-precision, and the parts with low-precision. Only a few of our existing products are listed below. If you have any needs for lathing parts, please feel free to contact us. We are confident to provide the product with high-quality, reasonable prices, and the best services.
Aluminum Motor Hub
This part is a connector on the motor shaft, which is used on a high-speed motor. It is processed by a CNC lathe. The material is Aluminum. The part is with smooth surfaces, lightweight, and high strength. This part belongs to high-precision lathing parts.
Knurled Steel Nut
This part is a medium precision lathing part. It is a round nut
with knurling on the periphery and threaded holes in the center hole. The
material is carbon steel with electroplating. The material can also be
stainless steel, Aluminum, brass, or copper. This kind of part is widely used
in machinery equipment and household products. It belongs to the more commonly
used lathing parts.
Lathed Aluminum Flange
This part is used for connection and sealing between structural
parts. The shape of the part is a ring with four small round holes. This part
is also a commonly used structural part, and the material can be Aluminum,
carbon steel, or stainless steel. The dimensional accuracy can be processed
according to customer requirements.
Aluminum Alloy Bushing
The part is a funnel-shaped Aluminum tube. The big end is a
threaded hole. It can be assembled between two circular parts with different
diameters to play a connection role. The material of this part is Aluminum,
which is light in weight and anti-oxidation.
Hexagonal Brass Shaft
This hexagonal copper shaft is often used for the installation
of electronic circuit boards and control boards. Its material is copper. One
end is a stud and the other end is a threaded hole. The machining accuracy of
this part is relatively low.
