Acute waist sprain, commonly known as flashing waist, is the acute tear laceration caused by the sudden pull of the waist muscles, fascia, ligaments, and other soft tissues such as external force, which often occurs when the heavy objects and waist muscles are contracted.Acute lumbar sprains can tear the adhesion points, osomas, fascia, and ligament of lumbosacral muscles.

The cause of acute lumbar sprain

There are two main reasons that cause damage to the waist soft tissue:

1. Limb sprain

Most of them are caused by walking, jumping, flashing body, and Running. Most of them are caused by muscle and ligaments, so the damage is lighter.

2. Bulberry and wounds

It is more serious damage, such as high force in the process of high climbing, tilted, and carrying heavy objects.Essence

Symptoms of acute lumbar sprain

After the patient was injured, the waist pain occurred, and there was a continuous drama. The next day, it was more serious due to local bleeding, swelling, and low back pain. Some of them only twisted the waist slightly.Essence

Limited waist activity is limited, you must not be straight, and it is difficult to prone, leaning, and twisting. Cough, sneezing, and urination can exacerbate the pain.

When standing, I often support the waist with my hands, and hold my hands in the chair with both hands when sitting to reduce the pain.

Pain occurs on one or sides of the lumbar muscles after sprains; sometimes it can be painful and overnight after being injured or overnight, and the waist activity is blocked. The pain is slightly lighter during static, and the pain is more painful when the activity or cough.During the examination, local muscles were tight, tender, and traction pain, but there was no congestion.

How to deal with waist sprain

1. Lie down as soon as possible

Lie down as soon as possible after the waist sprain to reduce the pressure of the muscle fascia tissue or the pressure of the lumbar spine, and relieve pain.For more severe sprains, we should rest in bed for at least 5-7 days.

2. Cold compress

Wrap the ice cubes with a plastic bag, wrap a thin layer of thin towels, or directly immerse cold water with a towel, and apply it to the pain site to directly reduce the pain. More importantly, cold compresses can shrink the capillaries and reduce the muscle fascia tissue bleeding.Change the towels every 1-3 minutes, 5-10 times in a row.The time to apply should not be too long, otherwise it will affect the normal circulation of the blood, which is counterproductive.

3. Do not press

Do not blindly press the acute stage, otherwise it will increase the bleeding of the muscle fascia tissue or cause disconses of intervertebral disc.

4, hot compress

After 48 hours, the damaged capillaries have stopped bleeding, and it can be changed to hot compresses at this time.Hot compresses can promote the absorption of congestion and blood circulation, so that the soft tissue is repaired as soon as possible.

5. Physical therapy

After the improvement of pain and spasm, some physical therapy can be done appropriately to accelerate the recovery of injury.There are many ways to physically therapy, with technical reset, infrared rays, local massage, acupuncture, and external application of Chinese medicine. You should depend on personal circumstances.

6. Use medicine

During bed rest, you can use analgesic relieving spasm, hemostasis and swelling ointment (such as Fusalin milk cream, Yunnan white medicine spray, etc.), but pay attention to the Skin cannot be used when the Skin is damaged.If necessary, you can take anti -inflammatory analgesic and neurotic nutritional drugs.

TIPS: If there is only waist pain, there is no symptoms of compressive nerves such as leg pain, numbness, weakness, and dysfunction of the legs. At this time, it is recommended that you do not have to rush to the Hospital for examination.If the symptoms of compression nerve occur, the lumbar disc herniation is likely to occur. It is recommended to go to the Hospital for examination.If there is only waist pain and the bed rest has not improved after 3-5 days, it is recommended to go to the Hospital for treatment to avoid developing chronic low back pain.

The treatment of acute lumbar sprain

The acute period should be restrained.Those with obvious tenderness points can be closed with 1%Protaine (or 1 ml of hydrogenate hydrogenate hydrogenate) for pain points and supplemented by physical therapy.You can also apply blood circulation, stasis, and analgesic plaster locally.After the symptoms are reduced, the back muscles are gradually started.

Prevention of acute waist sprain

1. Education employees should be publicized, strictly abide by operating procedures, familiarize themselves with production technology, prevent rough dryness, and eliminate the incidence of work injury.

2. Improve the labor conditions as much as possible, and replace the heavy physical labor with mechanical operations.Attention should be concentrated during labor, especially when collectively carried heavy objects, we should work together under unified command and consistent pace.

3. Master the correct labor posture. For example, when carrying and lifting heavy objects, try to make your chest and waist straight up, flex your hips and knees, and get up with your lower limbs.Take a half squat to make the object as close to the body as much as possible.

4. Strengthen labor protection. When doing heavy physical labor such as carrying, lifting, moving, and lifting, we should use the Belt to help stabilize the waist spine, enhance abdominal pressure, and enhance muscle work efficiency.If you work in a cold and humid environment, take a hot bath to remove cold and dampness and eliminate fatigue.Try to avoid working for too long for the forced posture of bending.

1. What are the differences between night vision glasses and Polarized glasses

1. Different principles

The polarizing mirror is made according to the polarization principle of the light, and the unnecessary light is scattered, such as strong sunlight.

Night vision mirrors are based on the auxiliary observation tools made by the night vision technology at the same time. The night vision technology includes two aspects: micro -light night vision and infrared night vision.

2. Different effects

The special effect of polarizing mirror is to effectively exclude and filter the scattered light in the beam, so that the light can put the eye visual image into the eye transmittance shaft, making the field of view clear and natural.

Micro -light night vision mirrors make the weak light large, so that it shows a clear picture in the sight, so when there is no light at all, the microcomioxid night vision mirror cannot be seen; the active infrared night vision mirror is inIn any case, you can see things. If there is no infrared source, passive infrared night vision mirrors cannot see things.

3. Different use of usage

Polaries can be used when driving, fishing, skiing, rain, etc. are used in strong reflection or strong light.

Night vision mirrors are usually used at night, and they are widely used in the fields of transportation, military and other fields.

2. How to choose night vision glasses

1. Material of the lens

The material of the lens affects the effect of protecting the eyes. You should choose the driving mirror made of polarized lenses. This can effectively reduce the dazzling Lights and the light of the Lights.The strong light becomes soft, and the vision is clearer, which also guarantees the safety of the driver's friends and relieves the fatigue of the eyes.If possible, let the salesperson darkens the light when buying, and feel the softness and clarity of the Lights after wearing the product.

2. The radian of glasses

The comfort of polarizing driver mirrors depends on the arc of glasses.Westerners' nose bridges are generally tall, and the contours of the bridge of our Orientals are round. Therefore, when choosing, you can try it. After wearing it, you can feel that it is easy to drop and hold the nose. It is most important to choose the glasses suitable for us.

3. The nose of glasses

When the driver friends buy the night vision mirror, they should choose the kind of soft and elastic nose. In this way, it will not make the nose of our major drivers feel uncomfortable.

4. Observe the mirror leg

The flexibility of the driver's mirror legs is also very important. Check out whether the mirror legs are flexible and whether the size can be adjusted to meet the needs of different drivers and friends. Flexible mirror legs will be easier to adjust and make drivers feel more comfortable.

5. Framework material

You should choose a driving mirror of the alloy material. The glasses made of this material are very light, the weight is not heavy, and it is strong. The ears will not be uncomfortable because of wearing glasses for a long time.

6. The thickness of the lens

The thickness of the driver's lens lens affects the use of glasses to a certain extent. Choosing glasses with thicker lenses can be more durable to prevent the glasses from being stimulated and unexpectedly crushed, effectively protecting the eyes of drivers and friends.

1. Do you need to verify the gliding umbrella?

The gliding umbrella is a high -altitude movement with a certain danger. It is currently under the management of the China Aviation sports Association. There is a complete set of examination training specifications. There are specialized glide umbrella pilots certificates. So do you need to verify the glide umbrella?

Generally speaking, gliding umbrella flights are divided into two modes, one is the experience mode of professional coaches flying. This does not require my own research. The glide umbrella coach must have a relevant certificate; the other is a single flight mode.It is necessary to verify that after the special technical training is required, the certificate can be obtained after assessment.

Some friends do not intend to be a special coach to fly, but they just fly casually by themselves. They may think that it is not a big deal to take the test. However, it is generally recommended to take a certificate. OtherwiseNo relevant insurance.

2. How many Levels of gliding umbrella certificates are divided into Levels

Global umbrella Certificate, the full name is the gliding umbrella pilot level certificate, a total of five Levels:

1. Class A: Flying on the ground, the gliding umbrella flying on a hillside of not more than 100 meters. Students who complete the primary training course can get the "Grade A Certificate of Global umbrella Movement" issued by the Chinese Aviation sports Association.

2. Grade B: High glide, gliding umbrella at a sufficient height (more than 300 meters) and flying above a certain area, complete intermediate training courses and pass subject assessment, under the condition that the flight time and flight times can beApply for upgrade.

3. Class C: Dynamic gas currents soar, gliding umbrellas use the power of the hillside to rise to the air flow to make a short time flying.

4. Grade D: Hot air currents soaring, gliding umbrellas use the heat to rise to the air flow for air, which belongs to the medium and senior flight grade certificate.

5. E -Class: Long -distance flight, gliding umbrella using the upside off -road flight from the take -off point, requires the pilots to accumulate considerable flight experience and flight hours.flight.

3. What are the conditions for gliding umbrella test?

Global umbrella Pilot Certificate is divided into five Levels of ABCDE. The conditions for certificates of different Levels are also different:

1. Class A

(1) Over 16 years old, with culture above junior high school.

(2) Qualification certificate of the medical examination at the county level.

(3) Complete the theoretical teaching parts stipulated in the training outline.

(4) The flight time is not less than 5 flight days, and the number of flights is not less than 20 times.

2. Class B

(1) Have a Class A certificate.

(2) The flight time is not less than 20 flight days, and at least 40 flights.

3. C level

(1) Have a B -level certificate.

(2) The total number of flights is not less than 100 times, and the total time is not less than 20 hours.1 hour.

4. D level

(1) Have C -Class Certificate.

(2) The total flight time is more than 50 hours, and there are 3 times not less than 2 hours (there are record certificates in the official competition).

5. E -level

(1) Have a D -level certificate.

(2) There are at least 3 flights of more than 50 kilometers in different rising airflows (in the formal competition).

Global umbrella tests need to be taken in order, and at least half a year is needed for each level.

The development of pattern skiing sports

Snow plates that can be freely slide forward with very short, forward and backward skiing projects such as skiing, rotation, jumping, and air turns can be done.In the early 1970s, North America began to popularize all kinds of skiing.In the early days, people only used the inertia of slippery and tried to perform single -foot balance, various cross -steps, single -footed rotation, and various jump rotation. Laterappreciate.Because this sport's requirements for venue equipment are not high, it is a very promising project.

Falling skiing project and rules introduction

Snow skills (Moguls)

It is a series of comparison techniques, air movements, and slippery speeds on steep slopes with a series of snow Bags, including single -person snow skills and double snow skills.Since 1992, the skills of men and women's singles are listed as the Winter Olympics project.

Aerials (Aerials)

It is a game with two different techniques jumping on the pre -prepared platform with the help of the inertia of steep slopes. In 1994, it was listed as the Winter Olympics project.

Ballet (Ballet)

It is a self -made program compared with technical actions such as taxi, pace, jumping, rotation, and air flipping with a certain slope with a certain slope.Essence

Pattern skiing equipment

Including skiing, skiing sticks, Ski boots, sportswear and gloves.Because the pattern skiing movements are relatively sharp and the impact is large, the skiing boards must be strong and durable.In addition to installing the desserter, the snow and air skills must also be installed with a stopper or a slide.The length of the Ski board can be determined according to the project, venue, technical level, and the technical characteristics of the athletes, but the rules stipulate that the shortest of the ballet ballet on the snow must not be as short as the athlete's personal height.180 cm (those who are less than 160 cm in height of men and women are allowed to shorten 10 cm).

Nike shoe code is too large or small

nike The size of the shoes is the same as many international sports flat cards. It has the distinction between the US code and the European code. The copy is what we often see us, eUR import nike When we come to the mainland, companies from the mainland will calibrate the size. Because it is produced abroad, foreign people's feet are larger than the Chinese feet, so the target is a little larger than the actual code, but the domestic production and release of the domestic market will be nike It is made according to the size of the Asian feet. It is the standard code, without the difference, so please see where the shoe you can see, and then look at the size.

However, the basis for sales in the mainland is the standard code, because the mainland is the largest production base in the world, not to mention in China, even in the United States, Japan, and Southeast Asia, many, many of them are made in China, don't worry too much.

In fact, we can start with the size of our feet.The best way to measure the size of the feet is to prepare paper, pen and ruler, so that your feet are placed on the paper with a standing posture, then draw a circle with the contour of the pen, then measure it with a ruler to measure the ruler.The length and width on the graphic are your feet length and feet width.

When selecting Nike shoe codes, you must make judgments based on your feet and feet width.Under normal circumstances,nike The shoe codes are made based on European foot type, and our Chinese feet will be slightly wider than Europeans.Therefore, when trying it on, you must first consider the width of the foot, and then consider the feet length.Both are right, and the shoes you buy back will fit.However, it is reminded that when you buy the new shoes, you will be a bit pinching, and Nike shoes are no exception. When you wear it a few times, this problem will be solved.Nike sneakers products & gt; & gt;
