What are the Diving equipment

1. Facial mirror

The diving mirrors on the market now are mainly divided into three types: silicone, rubber, and PVC; rubber and PVC materials generally have some odors. The rubber material has rarely appeared in the leisure market. Generally, a few diving mirrors are made of silicone materialsIt is non -toxic and tasteless. The price is slightly more expensive than PVC, but it is softer, more durable, and more comfortable to wear.

The appearance is mainly divided into dual lenses and single lenses. There are no differences in these two uses, and the field of vision is similar. The advantage of dual lenses can be equipped with close -up lenses; the selection is mainly based on whether it meets its face shape and personal preferences; there is another kind of one; there is also one is that there is one.Fullface mask; Full mask, the design of this type of mask makes the divers not have to include the respirator in the mouth and combine the communication interface, mainly to enable the diver to achieve underwater calls; mostly for engineering diving.

2. Breathing Tube

The material of the respiratory Tube is also mainly divided into silicone, PVC, which is better for silicone tubes; structures are divided into all-dry and non-dry type;It is welcomed by junior players to prevent water from entering; but from a practical perspective, it is still a traditional non -dry respiratory Tube with simple structure and smoother breathing.

Buying note: The choice of respiratory Tube must meet the principles of ergonomics and mechanical design. The diameter size and length must be appropriate to facilitate drainage, and the design of the water stop valve must be available to prevent seawater from pouring in.The part of the bite should be the best choice for bite comfort.

3. Cold -proof clothing

Cold -proof clothing, also known as diving suit.It is mainly divided into wet, semi -dry, all -dry, wet type divided into 3 mm, 5 mm, 7 mm and other thickness.Wearing semi -dry and full -drying potentials, you can keep your body not wet, and you can also wear warm clothes in the interior. The insulation effect is the best.The choice of diving coats is mainly determined according to the water temperature of the diving environment; tropical or temperate waters, 3 mm thick wetwear are the most commonly used; the lower the water temperature, the thicker the need to choose a divingSemi -dry or full -drying; all dry clothes can even achieve under ice diving.

Buying note: In order to achieve the effect of preventing the cold, the cold -proof clothing must be fitted, soft, easy to unload, and not easy to deform, and does not affect the ability of divers to move.Secondly, choose the tricks you like.

4. Frog shoes

The frog shoes are mainly packed with foot frog shoes, and the adjustable frog shoes; the set of foot can only be worn, light and easy to carry; suitable for snorkeling, or indoor, and diving on the board.The role is to enhance the driving force and maintain balance.Floating activities are generally selected. Many junior players can easily ignore the role of frog shoes.

In fact, diving in the wild, frog shoes are more important than respiratory Tube. Wearing frog shoes at least half a life jacket.

5, buoyancy regulating vest

The BC style is mainly divided into jackets, system, backup type; bribium type is mostly used for technical diving.There are many models of BC, and there are many details in different brand models. When choosing, you should according to the specific needs of your personal; there is also a pre -type BC that is no longer used for water diving.It is very popular in snorkeling activities.

Buying note: The buoyancy regulating vest should be different due to the weight of the personnel, so you need to choose a buoyancy regulating vest suitable for personal weight.

6. First -level regulator

A diving brand has a variety of types of regulators to choose from, which is suitable for different needs; taking scubapro regulator as an example, MK2 is suitable for most leisure diving and diving training; MK17 is a fully enclosed design, especially suitable for ice diving, polluting water sources, etc.Special environment diving; MK25 can be used for large -depth diving.

Buying note: The first -level regulator and the secondary regulator are a group of combinations. The difference is that the first -level regulator is connected to the gas cylinder, while the secondary tunnel is used in the part of the mouth.

7. Second -level regulator

The regulator (also known as the respiratory) is divided into single Tube and dual -Tube type. When choosing, you should cooperate with your mouth shape and snake Tube.When cleaning and cleaning up, it should be placed in an environment where dry and is not easy to contact with salt, and should be checked once at least two years.

The spare secondary regulator is the standard and training subject in leisure Diving equipment.But I personally think that there is basically no chance to use it.If you need to spare gas sources, a better choice is to equip an emergency gas cylinder.

8. Diving instrument

The diving instrument has a single pressure gauge, a two -connected table, and a three -meter table; the single pressure gauge can only display the pressure of the gas cylinder, so that the diver can know the gas of the gas cylinder at any time;The depth of the pressure and the diver is located; one more northern needle of the three -meter table, when the diver needs to master the direction; there is also a rare four -meter table, an additional thermometer.

9. gas cylinder

The gas cylinder is divided into steel cylinders and aluminum bottles.Leisure diving mainly uses imported 12 -liter aluminum bottles. The aluminum bottle is resistant to corrosion resistance and long life.There are some supporters of domestic 12 -liter steel bottles and aluminum bottles in the underwater operation market. The main features are cheap, but the cylinders are easy to rust, and some new steel bottles have odors.

Buying note: depends on the depth of water and the amount of gas needed by the individual, and cooperate with your body shape and physical strength to choose the appropriate gas cylinder.Therefore, too long or too large gas cylinders will affect the ability of activity; and choose to prepare a gas cylinder with air storage device as much as possible.

10. Dignation

Due to the large buoyancy of the submersible, we must configure the heavy -duty and buoyant, otherwise the diver cannot be dived.The weight blocks are basically lead materials, which are divided into naked lead and environmentally friendly plastic lead blocks. The lead itself is toxic. It is recommended to use more safer plastic lead blocks.

11. hook, fast unloading ring

As the name suggests, it is used to help quickly load and unload the items around you.It is mainly used for Hanging cameras, flashlights, and knocks on the BC's Hanging ring.

12, gloves

Hands immersed in water are easily injured, so gloves are used to prevent injuries to being cut by thorns or sharp rocks.Depending on the water temperature, different thin gloves are optional.

13. Diving boots

Diving boots are mainly prevented from slipping in the slippery rocks.It is more suitable in China to use the foundation bottom, and it is more suitable for boat dives to use rubber bottoming shoes; and be careful to closely consolidate with frog shoes.

14. Diving knife

It is used to cut off the remaining fish or fish network cables in the sea to avoid entangled divers.It is a guarantee of diving safety.Ordinary stainless steel dive knives cannot remain sharp in seawater and are easy to rust.A better knife is a titanium alloy diving knife, light weight, sharp, never rust, but the price is higher.

15. lighting in the water

It is used to spy the dark world in the sea. The greater flashlight and lighting Lights are particularly effective. It is a must -have for diving at night or dark fields.

16. record board in water

Instead of communicating in water, in addition to communicating with gestures, another pipeline is to record the board in the water and write it down as a two -way between staff.

17. Diving computer watch

Diving computers have gradually become standard accessories that have gradually become diving activities.It is mainly used to ensure that divers stay within the depth and time limit.record the diving process, etc.

How much is a Diving equipment?

If it is snorkeling: the face mirror breathing Tube is sufficient, and dozens of RMB to hundreds of dollars can choose.

Deep diving (water diving): diving mirror, respiratory Tube, foot scallion, first -class head, secondary head, buoyancy regulating vest, three -meter table, gas cylinder, Diving clothes, etc., are about 4,000 in domestic. If the brand, the priceIt will be higher.

How big size of the Dog's foothills

If you have observed Dogs to sleep, you will find that they usually appear curled up when they sleep, but this does not mean that the Dog's nest is enough to curl up.The Dog's nest does not necessarily need to make it completely straight to sleep, but at least it must be able to lying comfortably in the surrounding position.

Dog cage advantages and disadvantages

Dog Cage advantage

Let the Dog sleeping Dog cage restrict its freedom and avoid the Dogs from defecating or even demolishing the house at night.When we are not at home, we can keep the Dogs in the cage so that it can avoid it from being destroyed.It can also avoid Dogs randomly.

Disadvantage

When the Dog just started sleeping the Dog cage, it will have resistance because of fear, because there is no sense of security, it will always be in the cage, and it will always call out a lot of movements, which will make people rest well.The cage hurts the Dog from time to time. For example, the paw is stuck in the cage seam, and the Dog's nails are injured by a cage. (The quality of the cage is particularly important.

Summarize:The puppies who have just bought are more suitable for Dog cages to avoid Dogs and destruction.

What kind of choice of Dog nests

1. Square

One of the types of kernels on the market is a box -shaped Square doghouse.The surrounding of this kernel's nest is surrounded, and the shape looks like a very shallow box.Dogs can use the edges as pillows and sleep on the edges.The cushion in the middle of the Dog's nest is usually removed, which is more convenient when cleaning.

2. Dingding

The dome -shaped Dog nest, as the name implies, is a kind of top doghouse, which is usually divided into two types: semi -cover and full coverage.This Dog nest is most suitable for use in winter, and it can play well in the cold space.

precautions for buying Dog nest purchase

1Fabric of the kernel's nest

Most of the fabrics on the market include cotton, acrylic, and velvet. The main filling is: sponge, cotton,PPcotton.Of course, if you want to choose, the cotton fabric must be the first choice. First, it is not easy to generate static electricity because the sensitivity of the animal organs is much higher than that of humans, so try to avoid some irritating things.Harmful substances; followed by velvet cloth, it is also very warm and comfortable; acrylic's fabrics are the least recommended. Because of the low cost, acrylics are relatively cheap, but after Dog hair and acrylic contact, it is easy to knot.The best filling isPPCotton, keep warm, and can air dry quickly; secondly, choose cotton, keep warm and healthy, but it is inevitable that the Dog's nest will dip some urine or something., Keep warm and the cheapest price.

2

If it is a large Dog, you can choose the wooden kernel nest first. If it is cotton's kernels, it is best not to have too many ornaments. The simple appearance of the kernel nest is often easier to clean.Disclosure can be more convenient.Summary two points. Large Dogs try to choose wood as much as possible. If you are dirty, you can use a brush and water to directly use it. The small Dogs choose to use simple and practical to minimize the decorations. The market is mainly based on round and Square pits.

3, Pay attention to details

Nowadays, the Dog's foils are endless, and the functions are complicated and diverse.We still follow the principle of practical priority, try to choose the Dog's nest that is practical and not easy to lose, and try to buy as little color as possible, beautiful appearance but not practical.Dogs are relatively naughty. If the quality is not good, it is easy to lose, and the Dog's own vision is not good. It can not understand it if you buy it.

4Internal settings

Another thing is to talk about the settings inside the Dog's nest. Generally, you can lay a warm and comfortable cushion. There are several characteristics of the mat.It is more practical and convenient to take the old clothes at home, which is more practical and convenient.

At 9:44 am on November 15, 2020, Eastern Time, there have been more than 2 million people in the world's new crown pneumonia.Behind the rising numbers, the ventilator is still short.According to the "Liuye knife" research, more than 50%of new coronary pneumonia patients will have difficulty breathing, and the use of non -invasive ventilation machines can improve symptoms.

On March 30, 2020, the US Food and Drug Administration (FDA) began to issue emergency use authorization (EUA) for non -invasive ventilator.On March 31, 2020 (April 1, Beijing time), Yuyue Medical was authorized, becoming the first domestic non -invasive ventilator R & D manufacturing enterprise in China, marking that Yuyue has obtained a pass to the United States resistance.

The threshold for approved speed -up is unchanged

Global gaps, Chinese aid.On the road of ventilator exit, the EU CE certification and the US FDA certification are the two most important pass permits, representing the entry threshold of the world's mainstream markets.According to statistics from the Ministry of Industry and Information Technology, only 8 of the 21 ventilator manufacturers across the country have obtained CE certification.

Earlier, Yuyue has obtained medical device registration certificates issued by the China State Drug Administration (NMPA), the EU CE certification, and the FDA urgently authorized authorization, Yuyue Medical has become one of the few "three certificates in hand in hand in hand"Medical brand.

fish Yue Win -clean Vecent Production Line

It is understood that the FDA registration cycle of the ventilator usually takes at least 6-9 months.In order to fill the ventilator gap as soon as possible, the FDA pressed the fast -forward key, but it did not reduce the requirements for applying for enterprises. It still has strict standards in terms of enterprise scale and quality management.

Anti -epidemic weapon again to fight international

Non -invasive ventilator played a key role in the anti -epidemic war in China.Several experts point out that most patients should be treated in a timely or medium period of the disease. If they find hypoxemia, it should be treated with non -invasive ventilator or high -flow oxygen therapy in time, which can greatly prevent patients from entering the critical stage.

Doctors in Wuhan Hospital use fish leapless ventilator

According to statistics from the Ministry of Industry and Information Technology, in February 2020, China's ventilator output was about 15,000 units.As an important supplier of the world's unsecured ventilator, Yu Yue assisted 7,000 units nationwide, which is equivalent to half of the half -wall of China's non -invasive ventilator, which provides strong support for winning the Battle of Hubei and Wuhan's defense war.

A doctor who assisted the front line of Wuhan said that the operation of fish jump non -invasive ventilator is simple: "10 parameters show the same screen, and the blood oxygen pulse rate is simultaneously reducing the burden of fish leaps and opening the life channel for patients."

In order to put it into use as soon as possible, the export ventilator also equipped with auxiliary materials such as English use manuals, installation guidance videos, and common questions answering questions to help international doctors quickly be familiar with the equipment and scramble for patients.

The Tao is not far away, and there is no other country.Under the epidemic, professional, accurate and efficient aids are the wisdom of Chinese wisdom and the role of China under the epidemic.The epidemic will eventually end. After experiencing the test test, the community of human destiny will eventually usher in a better tomorrow!
