Why is the epidemic coming back?

The mismatch of the new crown vaccine + the mutation of the virus + the slack prevention and control of the epidemic has led to the fourth wave of upward trend in the overseas new crown epidemic.

With the continuous vaccination of vaccines, the epidemic should gradually recede. But in fact since March 2021, the global new crown epidemic has shown signs of continuous rebound, and the number of new confirmed cases in a single day has once again soared.

In the past five days (April 20-April 24), the number of newly confirmed cases abroad in a single day reached 759 thousand, 787 thousand, 849,000, 1.070 thousand, and 865,000 respectively, compared with February 2021 The daily level of 300,000 to 400,000 new cases has almost doubled, and it has refreshed the previous historical high in December 2020. The WHO also stated at a recent press conference that the current situation is close to the highest infection rate since the outbreak.

The overseas new crown epidemic is experiencing a fourth wave of upward movement (the first wave is in March 2020, the second wave is in July 2020, and the third wave is in December 2020).

Status of the epidemic in India

As the epidemic situation eased at the beginning of the year, epidemic prevention and control measures in various countries have been loosened, especially in populous countries such as Brazil and India. The people's failure to observe the prevention and control measures such as wearing masks and maintaining social distancing, and holding large-scale gatherings caused the epidemic to break out on a large scale again. If you work in airports, railway stations, large supermarkets, hospitals and other places, the intelligent ultraviolet disinfection robot and disinfection door will be your right-hand man in disinfection.

India is the country with the worst epidemic in this round, and it is facing a situation of out of control. In the past 24 hours, there were nearly 400,000 new cases in a single day. There have been more than 300,000 new confirmed cases in a single day for several consecutive days, and it continues to set new highs. The cumulative number of confirmed cases has exceeded 17 million.

Another large-scale outbreak of the epidemic in India is closely related to the previous government’s approval of the opening of the Big Pot Festival. The Big Pot Festival is a very large religious gathering, which also includes bathing in the Ganges River. Almost a million people enter the Ganges every day Participate in religious ceremonies.

In addition, the vaccine progress is slow (the two-dose vaccination rate is less than 2%, and the one-dose vaccination rate is less than 10%. The United States has “stuck the neck” on key raw materials, causing major problems in the local vaccine supply), and the spread of mutant strains (locally) B.1.617 double mutated virus, in recent sampling, India B.1.617 virus has accounted for 70.4%) also objectively aggravated the outbreak of the epidemic in India.

The epidemic situation in India has become out of control. Due to the large number of patients and the shortage of medical resources, many local designated hospitals have even shared the same multifunctional hospital bed for two patients, and there has even been a nationwide oxygen shortage.

Medical oxygen generator exports

At the present, many countries including China rushed to aid India in an emergency. Hundreds of oxygen generators were delivered to it, including large-scale PSA medical oxygen generators. Small medical oxygen generator. Personal household oxygen generators, etc. As a leading manufacturer of oxygen concentrator in China, YG Engineering company is also increasing its production speed, and doing its best to let the Indian people use high-quality and efficient YG oxygen concentrators to resist the disease.

What are the benefits of a household oxygen generator？

With people's pursuit of health and lifestyle, oxygen concentrators are no longer the boring big machines in hospitals. They have been gradually optimized and gradually entered the public's homes. After entering the family, it has turned into a "healthy artifact". In the publicity of many businesses, the oxygen concentrator seems to help solve most of the uncomfortable symptoms encountered daily, and many healthy people have also chosen to inhale oxygen.

According to the survey, many home oxygen concentrators on sale claim that in addition to curing diseases such as chronic lung obstruction and asthma, they also have many health benefits: relieve stress and relieve fatigue; provide oxygen to the skin, which has beauty effects; pregnant women inhale oxygen It can promote the growth and development of babies and other magical effects, but are these true? Today I will give you answers one by one.

What is the best household oxygen generator?

A household oxygen generator is a device that can produce oxygen. It can be used to correct body hypoxia and oxygen therapy. It is characterized by inhaling oxygen directly to increase the oxygen content of the arteries, rather than acting on a certain part of the body to indirectly improve hypoxia. Increase the body's continuous intake of oxygen throughout life.

Is the home oxygen concentrator really a "healthy artifact"?

Some experts pointed out that the oxygen concentrator has a certain effect on people with hypoxia, such as chronic obstructive pulmonary disease, asthma, bronchiectasis, gas poisoning, and other diseases. There is currently no evidence that oxygen can be used to make beauty. Oxygen inhalation is purely conceptual hype because the surface of human skin cannot directly absorb oxygen. Even though pressure oxygen injection, hand massage, etc., oxygen cannot enter the skin.

What are the benefits of a home oxygen concentrator?

The home oxygen concentrator is suitable for family use. The advantages are convenient and simple. It can not only help the hypoxic population but also help the health care problems of middle-aged and elderly people. However, one should pay attention to the purchase of a home oxygen concentrator and choose a medical-grade certificate. The oxygen concentrator is more secure, which is similar to the YG oxygen concentrator.

How to choose a household oxygen generator？

1. When choosing a household oxygen concentrator, you must choose a big brand. A manufacturer with a long-standing brand can guarantee its sustainable development and future maintenance services.

2. Medical device registration certificate. This is also very important. Medical-grade oxygen concentrators are more strictly controlled, and many household oxygen concentrators on the market are actually three-no products.

3. The oxygen concentration output by the household oxygen generator must be greater than 90% in order to maintain a stable output.

4. Be sure to choose an oxygen generator with a noise level of fewer than 45 decibels, otherwise, it will affect rest, especially at night. Click here to know more about PSA oxygen generator. 

How to choose a right drilling rig?

 

How to choose a drilling rig?

You need drilling equipment for various purposes. For example, drilling a well to obtain natural resources (water, oil, geothermal energy, etc.) to build a foundation, drill holes in a mine, and take samples from the ground.

 

It is necessary to determine the purpose of the drilling rig and what kind of terrain it is mainly operated on. Depending on the terrain, you can choose different types of drilling rigs: rotary drilling rigs, percussion drilling rigs, down-the-hole drilling rigs, top hammer drilling rigs (with high hammers), etc.

 

In order to make the best choice, it is important to determine whether the rig is used for core business or occasional use, especially if you are using the latest technology, or a rig that has been available for decades.

 

Security, reliability, and ease of use are also important factors that need to be considered, and there is a direct connection between them. According to the drill machine manufacturer's recommendations, the use of reliable and easy-to-operate drilling rigs can improve user safety.

 

It is also very important to define the type of movement required by the rig. There are crawler-type automatic drilling rigs and truck-mounted or trailer-mounted drilling rigs, which need to be powered by generators or trucks that carry them.

 

Once the type of rig required is determined, the required rig size can be calculated based on the diameter and depth of the hole.

When do you need to drill rig?

Drilling is required in many jobs, such as:

Drilling: used to obtain groundwater or oil.

Geothermal drilling: obtain and extract geothermal energy.

Pile-driving rigs that support buildings on unstable ground: up to 2000 mm in diameter and 70 meters in depth.

Micro pile drilling rigs, especially for drilling holes for reinforcement of existing structures: diameter between 150 and 200 mm, depth within 30 meters.

Blasthole drilling rig in the quarry.

The continuous rotary uses drill cuttings driven by the rotary drill machine to maintain the borehole wall.

Drilling is usually done vertically, but it can also be horizontal or directional, for example for anchoring.

Which type of drilling rig should I choose?

There are two main types of drilling rigs: automatic crawler type and truck-mounted or trailer type.

If you need to move at a low speed on uneven areas or very soft ground, you can choose a crawler drill. The stability of the rig depends on the surface area of the track. Therefore, the wider the crawler, the more stable the drilling rig. But when the track is too wide, when moving, especially when turning, it tends to wear faster and damage the ground. The crawler drilling rig has a travel speed of about 4km/h, so it is more suitable for operations that require little travel.

Truck-mounted or trailer-mounted drilling rigs are not autonomous in mobility or energy. These energy sources may come from transport trucks or independent generators. However, this type of drilling rig is much lower in cost than crawler drilling rigs. Click here to know more.
