Necessary knowledge of wheelchair selection and use

  Wheelchairs are widely used in patients’ rehabilitation training and family life, such as lower limb dysfunction, hemiplegia, paraplegia below the chest and people with mobility difficulties. As patients’ families and rehabilitation therapists, it is very necessary to know the characteristics of wheelchairs, choose the most suitable wheelchairs and use them correctly.Therefore, 電動輪椅 Only then will more and more pump owners cheer for it and spread the value and function of the brand. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  First of all, what harm will an inappropriate wheelchair do to the user?

  

  Excessive local compression

  

  Form a bad posture

  

  Induced scoliosis

  

  Causing contracture of joints

  

  (What are the unsuitable wheelchairs: the seat is too shallow and the height is not enough; The seat is too wide and the height is not enough)

  

  The main parts that wheelchair users bear pressure are ischial tubercle, thigh, popliteal fossa and scapula. Therefore, when choosing a wheelchair, we should pay attention to whether the size of these parts is appropriate to avoid skin wear, abrasions and pressure sores.

  

  Let’s talk about the choice of wheelchair, which must be kept in mind!

  

  Choice of ordinary wheelchair

  

  Seat width

  

  Measure the distance between two hips or between two legs when sitting down, and add 5cm, that is, there is a gap of 2.5cm on each side after sitting down. The seat is too narrow, it is difficult to get on and off the wheelchair, and the hip and thigh tissues are compressed; The seat is too wide, it is difficult to sit still, it is inconvenient to operate the wheelchair, the upper limbs are easy to get tired, and it is difficult to get in and out of the gate.

  

  Seat length

  

  Measure the horizontal distance from the hip to the gastrocnemius of the calf when sitting down, and reduce the measurement result by 6.5cm. The seat is too short, the weight mainly falls on the ischium, and the local pressure is easy to be too much; If the seat is too long, it will compress the popliteal fossa, affect the local blood circulation, and easily irritate the skin of this part. It is better to use a short seat for patients with extremely short thighs or flexion and contracture of hips and knees.

  

  Seat height

  

  Measure the distance from the heel (or heel) to the popliteal fossa when sitting down, and add 4cm. When placing the pedal, the board surface should be at least 5cm from the ground. The seat is too high for the wheelchair to enter the table; The seat is too low and the ischium bears too much weight.

  

  seating washer

  

  In order to be comfortable and prevent pressure sores, a seat cushion should be placed on the seat, and foam rubber (5~10cm thick) or gel cushion can be used. To prevent the seat from sinking, a piece of plywood with a thickness of 0.6cm can be placed under the seat cushion.

  

  Backrest height

  

  The higher the backrest, the more stable it is, and the lower the backrest, the greater the range of motion of the upper body and upper limbs. The so-called low backrest is to measure the distance from the seat surface to the armpit (one arm or two arms extend forward horizontally), and subtract 10cm from this result. High backrest: measure the actual height from the seat surface to the shoulder or back pillow.

  

  Handrail height

  

  When sitting down, the upper arm is vertical and the forearm is flat on the armrest. Measure the height from the chair surface to the lower edge of the forearm, and add 2.5cm. Proper armrest height helps to maintain correct posture and balance, and can make the upper limbs placed in a comfortable position. The armrest is too high, and the upper arm is forced to lift up, which is easy to fatigue. If the armrest is too low, you need to lean forward to maintain balance, which is not only easy to fatigue, but also may affect your breathing.

  

  Other auxiliary parts of wheelchair

  

  Designed to meet the special needs of patients, such as increasing the friction surface of the handle, extending the brake, anti-shock device, anti-skid device, armrest mounting arm rest, wheelchair table to facilitate patients to eat and write, etc.

Trump proposes _interest_free loan to aid Ukraine_ Ukrainian Foreign Minister says it may be considered

To some extent, https://www.tpwallet2025.cn Our development has surpassed many peer businesses, but it has never stopped moving forward. https://www.tpwallet2025.cn

According to Agence France-Presse reported on March 19, Ukraine Foreign Minister Dmitry Kuleba said on the 19th that Ukraine was shocked by the continued obstruction of a key budget plan to help Kiev resist Russia in the U.S. Congress. The plan has been deadlocked for months.

Reported that he said at an online briefing to foreign media: What is really important and shocking to us is that the decision has not yet been adopted. It is approaching the end of March, but discussions continue.

However, Kuleba believes U.S. aid will eventually come. He pointed out: This is a question of confidence in the ability of the United States to support countries that follow the rules and principles that the United States defends around the world, far beyond the scope of Ukraine alone.

The foreign minister stressed that Ukraine does not rule out Trump’s idea of providing aid in the form of loans rather than grants, but needs to know more details.

The report mentioned that the day before, Republican Senator Lindsay Graham, one of Trump’s loyal supporters, visited Kiev. He supported the former US president’s proposal to provide assistance to Ukraine in the form of an interest-free loan.

Kuleba responded: We are not shocked to hear this suggestion from the United States. We really need to study the details.

Reported that the Biden administration has been calling for months for the passage of a new Kiev aid plan, including $60 billion in military and economic aid. The plan has been approved by the Democratic majority in the Senate, but is still blocked in Congress.

Passage of the plan depends on the goodwill of Trump’s supporters in the House. Trump supporters have refused to review the current plan due to differences over U.S. immigration management. (Compiled by Zhao Kexin)

New study_ Antarctic ice shelf melt water much higher than previously predicted

In order to achieve the goal, composite decking Turn cocoon into butterfly, constantly polish product quality, improve business ability, and finally have a place in the market. http://www.goreverwpc.com/

Beijing, July 17: An international study recently found that in January, when the Antarctic summer temperature is the highest, 57% of the melt water on the Antarctic ice shelf exists in the form of snow and mud. However, under normal circumstances, regional climate change models do not include This part of the melt water is calculated. This means that the amount of melt water on the Antarctic ice shelf is much higher than previously predicted.

Researchers from the University of Cambridge and other institutions in the United Kingdom published an article in the latest issue of Nature Geoscience that they trained machine learning models to analyze the monthly surface melt water records of 57 Antarctic continental ice shelves between 2013 and 2021. As well as mapping the snow and mud of the Antarctic ice shelf, it was found that in January, when the temperature in the Antarctic summer was the highest, 57% of the melt water on the Antarctic ice shelf existed in the form of snow mud, which is, snow soaked in water. The rest of the meltwater exists in surface ponds and lakes.

Researchers said that people usually use satellite images to map meltwater, but from the images, only meltwater lakes, etc. can be identified with the naked eye, and snow and mud are difficult to identify because it looks like the shadows of clouds. Machine learning models can use more satellite information such as light wavelengths to determine which areas are named snow and mud, making it possible to more accurately measure the amount of water melted on the ice shelf.

The study found that in the five major ice shelf areas, the amount of water melted on the Antarctic ice shelf caused by surface melt water was 28 times higher than predicted by standard climate models.

The surface melting of the Antarctic ice shelf mainly occurs in the summer of the southern hemisphere. Whether it is slush or melt water existing in surface ponds or lakes, it will affect the stability of the ice shelf and lead to sea level rise.

Take you to understand the basic structure of the electric wheelchair.

  Before introducing different configurations of electric wheelchairs, let’s first understand the basic structure of electric wheelchairs. Electric wheelchair is usually composed of motor, controller, battery, frame and other main parts. The motor is responsible for driving the wheels, the controller controls the speed and direction of the motor, the battery provides electric energy, and the frame supports the whole structure. Different configurations of electric wheelchairs are different in these parts, which will be introduced in detail below to help you understand.know 電動輪椅價錢 Our growth has to go through many hardships, but entrepreneurs are never afraid and boldly move forward. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Motor: The motor of electric wheelchair is its core component, which directly affects the performance of wheelchair. At present, the electric wheelchairs on the market usually adopt DC Motor and AC Motor. DC motor usually has a high speed and is suitable for use on flat roads, while AC motor has a large torque and is suitable for driving on ramps and uneven roads. In addition, the power of the motor is also a key factor in the selection. The greater the power, the stronger the climbing ability and load capacity of the electric wheelchair. Therefore, when choosing an electric wheelchair, it is necessary to choose the appropriate motor type and power according to the user’s needs and specific use environment. In the difference between electric wheelchairs, it is necessary to distinguish between brush motors and brushless motors, and between AC motors and DC motors.

  

  Brushed DC motor refers to a DC motor that uses a carbon brush to contact with a rotating armature to exchange polarity and provide current. Brush provides current to armature through power supply when armature rotates, so it is also called carbon brush motor. Its advantages are simple structure and low use cost, but the brush is easy to wear and has limited service life, and at the same time, the brush will also produce electric spark interference, which will lead to high noise of the motor and is not suitable for high-precision applications.

  

  Brushless DC motor refers to a DC motor that uses an electronic commutator to control the phase sequence of the motor, without using a brush to contact the armature. Its advantages are long life, high efficiency, low noise, stable operation and fast response, so it is widely used in high-precision application fields such as high-performance power tools and electric vehicles. Disadvantages are complex structure and high cost.

German media: Ukraine systematically attacks Russian oil facilities with drones

Ukraine is systematically attacking Russian oil facilities with drones and achieving results again, German news television channel reported on March 13.

It is reported that three drones caused a fire at an oil refinery in Liangzan prefecture southeast of Moscow. The new Shahjinsk oil refinery in Rostov-upon-Don was also attacked. The latter is reported to be the largest oil refiner in southern Russia.

A source from Ukraine’s State Security Service told the Ukrainian newspaper Truth: we are systematically implementing a well-planned strategy to weaken the economic potential of the Russian Federation. Our task is to deprive the enemy of resources. He said the military’s fuel supply and Russia’s oil revenue for the war would be affected.

Reported that Ukraine hopes that the continued crackdown on Russian oil facilities can significantly reduce Russia’s fuel production. “Spring sowing in Russia will become very difficult, which means food prices will rise sharply,” former Deputy Minister of Internal Affairs Andr é Graschenko wrote on social platform X. Fuel shortages may also push up the prices of other commodities, he said.

A total of 58 Ukrainian drones were shot down by Russian air defense systems from midnight to early morning on March 13, the Russian Defense Ministry said. So far, however, the Russian military does not seem to have found a way to deal with Ukraine’s constantly developing and upgrading drones.

Itar-Tass quoted Kremlin spokesman Peskov as saying on the 12th: our soldiers are taking all necessary measures. He said that the air defense system is operating effectively, and whether the protection of industrial targets should be strengthened is a question to be answered by the Ministry of National Defense.

Putin said in an interview that the attacks are aimed at interfering with the upcoming presidential election. (compiler Wang Ting

Modern electric wheelchairs usually use lithium batteries as power supply.

  It is the energy source of electric wheelchairs, which can be divided into lead-acid batteries and lithium batteries. The voltage of electric wheelchairs is generally 24v. The different ah capacity of batteries directly affects the overall weight, endurance and service life of wheelchairs. With the continuous development of lithium battery technology, modern electric wheelchairs usually use lithium batteries as the power source.To get brand praise, 電動輪椅價錢 It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Lithium batteries have the advantages of high energy density, light weight and fast charging speed, which can provide a longer cruising range. There are also 6AH lithium batteries in the market that meet the standards of air boarding. People with disabilities and mobility difficulties can travel with portable electric wheelchairs and batteries.

  

  If the 20ah lead-acid battery is compared with the 20ah lithium battery, the lithium battery has a lighter weight and a longer battery life, and the life of the lithium battery is relatively long, about twice the life of the lead-acid battery, but the cost of lithium battery will be higher. Lead acid, on the other hand, is relatively more economical, and there are many after-sales points of electric vehicles under the domestic battery brands such as Chaowei, which is convenient for maintaining batteries and replacing carbon brushes, and can meet the needs of users for long-term use.

  

  At present, lithium battery electric wheelchairs are mainly used in portable electric wheelchairs, which are relatively inferior to lead-acid in battery life. The later replacement cost is also high. Here, you can refer to the approximate cruising range of the battery collected by Xiaobian. The battery life will be different due to different road conditions, different people’s weights and continuous exercise time.

Brazilian Senate sets up investigation committee to crack down on match_fixing

The data shows that, https://www.hualvtj.com Its development potential should not be underestimated, and it is also the inevitability of its existence. https://www.hualvtj.com

Rio de Janeiro, March 12 (Reporter Zhao Yan) The Brazilian Federal Senate announced at a plenary session on the 12th the establishment of a parliamentary investigation committee to investigate cases of fixing football match results, hoping to severely punish match-fixing.

This committee consists of 11 members, appointed by representatives from all parties in Parliament. According to a report by Brazil’s “Sao Paulo” on March 4, of the approximately 9000 Brazilian football matches monitored by sports betting radar in 2023, 109 (approximately 121% of the total) were suspected of playing match-fixing, ranking first in the world.

On the 11th of this month, the Prosecutor’s Office of the Federal District of Brasilia issued a search and arrest warrant against two Santa Maria players, accusing them of directly participating in match-fixing in two games in the state league. Evidence collected by the investigation showed that the two men used methods including deliberately being awarded penalty kicks, deliberately marking errors, and even making an own goal to make the team lose the game.

In December last year, the Brazilian Congress passed the online sports betting bill, which officially came into effect after being approved by President Lula. At the end of January this year, the federal government established a Bonuses and Gaming Secretariat, which is responsible for regulating and supervising the sports betting and online gambling industries.
