A fracture is a complete or partial break in the continuity of a bone structure. It is most common in children and the elderly, but also occurs in young and middle-aged people; with timely and appropriate treatment, most patients can recover their original function; a small number of patients can be left with varying degrees of sequelae.

Types of fractures.

1. Closed fracture: the skin at the fracture is intact and the fracture end is not connected to the outside world.

2. Open fracture: The trauma wound is deep to the fracture or the fracture end pierces the skin to expose the surface of the body.

3. Compound fracture: the fracture end damages blood vessels, nerves or other organs, or is accompanied by joint disarticulation, etc.

4. Incomplete fracture: the integrity and continuity of the bone is not completely interrupted.

5. Complete fracture: the integrity and continuity of the bone is completely interrupted.

2. The causes of fracture

(1) Direct violence

The fracture is caused by the direct action of violence on a part of the bone, resulting in a fracture of the injured part, often with varying degrees of soft tissue injury. For example, if a wheel hits the lower leg, a fracture of the tibiofibular stem occurs at the place of impact.

(2) Indirect violence

Indirect violence is caused by longitudinal conduction, leverage or torsion, such as a fall from a height and landing on the foot, the trunk is sharply flexed forward due to gravity, and a compression or burst fracture occurs at the junction of the thoracolumbar spine.

3. Proprietary signs of fracture

Pain, swelling, deformity, bone rubbing sound, functional impairment, hemorrhage.

4、Fracture treatment

(1) Reset

The fracture ends that have been displaced after the fracture will be restored to normal or close to the original anatomical relationship in order to regain the brace role of the bone. The methods of repositioning include closed repositioning and surgical repositioning.

(2) Fixation

After fixation, the fracture is easily re-displaced because it is unstable, so different methods should be used to fix it in a satisfactory position to make it heal gradually.

Commonly used fixation methods are: small splints, plaster bandages, external fixation braces, traction brake fixation, etc. These fixation methods are called external fixation.

If it is fixed by surgical incision with plates, steel pins, intramedullary pins, screws, etc., it is called internal fixation.

(3) Functional exercise

Through muscle contraction of the injured limb, increase the blood circulation of the tissue around the fracture, promote fracture healing, prevent muscle atrophy, and prevent joint adhesion and joint capsule contracture by active or passive activities of the unfixed joint, so that the function of the injured limb can be restored to the normal state before the fracture as soon as possible.

5、Fixation material of fracture: splint

Fixation material splint or its substitutes (such as wood, bamboo stick, bark, etc.). The dressing needs to be lined with soft materials such as cotton, gauze, towels, etc. between the splint and the skin, and then the splint is tied and wrapped with a triangular towel, bandage or rope.

(1) Fixation of upper limb fracture

The splint is placed on the outer side of the fractured upper arm, and the protruding part of the fracture should be padded, then the elbow and shoulder joints should be fixed, and the upper arm should be flexed and suspended in front of the chest with a triangular towel, and then the injured limb should be fixed in the thorax with a triangular towel.

(2) Fixation of lower limb fracture

Lower leg fracture fixation method: Place the splint on the outside of the fractured lower leg, with padding on the protruding part of the fracture, then fix the upper and lower ends of the wound and the knee and ankle joints (8-way fixation of the ankle joint), and then fix the top of the splint.

Thigh fracture fixation method: place the splint on the outer side of the fractured thigh, the protruding part of the fracture should be padded, then fix the upper and lower ends of the wound and the ankle and knee joints, and finally fix the lumbar, iliac and ankle parts

(3) Fixation of vertebral fractures

6. Fixation of cervical fracture

Use a cervical brace or head immobilizer to prevent further injury to the cervical spine, which can cause damage to the vital center and thus lead to cardiac and respiratory arrest and death.

b. Fixation of thoracic and lumbar spine fractures

Use a spinal board or multiple people moving together to keep the head, trunk and lower extremities in a straight line to prevent causing paraplegia.

6、First aid principles and precautions.

1. Pay attention to the wound and general condition. If the wound is bleeding, the bleeding should be stopped first and the fracture should be fixed only afterwards. If there is shock or respiratory or cardiac arrest, resuscitation should be performed immediately.

2. When dealing with open fractures with exposed fracture ends, clean and disinfect the area, wrap the wound with gauze, position the injured limb as normal as possible and let the fracture ends retract naturally, and forbid to send the exposed fracture ends back into the wound to avoid wound contamination and re-stabbing the blood vessels and nerves, and then dress and fix.

3. For fractures of the thigh, calf, and spine, the patient should generally be fixed in place, and the injured limb and trunk should not be moved too much during fixation to avoid increasing the patient's pain and injury to the nerves and blood vessels, and do not reset blindly to avoid aggravating the degree of injury.

4. In order to fix the fracture securely and firmly, the length and width of the splint used to fix the fracture should be commensurate with the fractured limb, and its length should generally exceed the upper and lower joints of the fracture.

5. The splint used for fixation should not directly contact the skin. When fixing, soft materials such as gauze, triangular towel pad, towel and clothing can be used between the splint and the limb, especially the ends of the splint, the protruding parts of the joint bones and the interstitial parts, which can be appropriately thickened to avoid skin abrasion or local tissue compression necrosis.

6. The tightness of fixation and binding should be appropriate, too loose to achieve the purpose of fixation, too tight to affect blood circulation, resulting in limb necrosis. When fixing the limbs, the finger (toe) ends should be exposed so that the blood circulation of the limbs can be observed at any time. If you find that the fingers (toes) are pale, cold, numb, painful, swollen, and the nail bed is bruised, it means that the fixation and binding are too tight and the blood circulation is not good, so you should immediately loosen and re-bind the fixation.

7. When fixing fractures of the extremities, the upper end of the fracture break should be tied first and the lower end of the fracture end should be tied later. If the binding order is reversed, it will lead to re-dislocation. For upper limb fixation, the limb should be tied in flexion (flexed elbow); for lower limb fixation, the limb should be tied in extension.

8. When fixing a fracture, the upper end of the fracture should be tied first, followed by the lower end. Reversal of the binding order may lead to repositioning of the broken end.

9. The upper limb should be fixed in a flexed elbow position; the lower limb should be fixed with the limb extended (pulled) straight.

10. To prevent heat stroke in summer and to keep warm in winter.

11. To prevent shock caused by pain, the casualty can be given appropriate application of sedative painkillers under the guidance of a doctor.

Searching for examination beds can be an overwhelming task. Due to the various clinical settings designed to treat different patients with different issues, there are multiple types of exam examination beds that correspond with each setting.

In efforts to simplify your search, here are the 10 types of examination beds:

1. Manual Examination Beds

Manual examination beds, also referred to as box examination beds, are your standard exam examination beds that focus on functionality, reliability, and practicality.

Manual examination beds also feature a headrest and adjustable footrest, and many come with extra storage within their cabinets and drawers. These examination beds typically feature a heavy-duty step to assist patients as they get onto the bed, which could be simple for some patients but demanding for others.

Depending on your clientele, manual examination beds could be a great choice, especially if you have a smaller space or work in a multi-practice clinic.

2. Power Examination Beds

Power examination beds, also known as high-low beds or electric beds, are the most popular types of examination beds. While manual examination beds have an adjustable headrest and backrest, they have fixed seating. Power examination beds, on the other hand, typically offer more adjustability ,therefore, they are available as an alternative to the more traditional manual option.

Some power examination beds can lift or lower the entire bed, while others can adjust individual parts. Having the powered options reduces the energy, exertion, and time it takes to adjust the bed, and it keeps patients comfortable. These are great for practitioners who provide in-office procedures, but really, any doctor would benefit from a power examination bed. Its effortless convenience for handling patients, as well as its easy accessibility make these beds a solid choice.

3. Procedure Examination Beds

Procedure examination beds, also referred to as procedure chairs, are designed to comfortably assist medical professionals during minor procedures.

Prioritizing patient comfort and practitioner movability, most procedure chairs have an adjustable height feature, along with preset positions to ensure a hassle-free procedure performance.Some procedure examination beds also have pre-programmed positions that adjust the bed to the specific procedure that is being performed.

4. Treatment Examination Beds

Treatment examination beds include massage examination beds, therapy examination beds, h-brace examination beds, and traction examination beds. There are treatment examination beds with storage drawers underneath the seated area, but most are quite simple to easily perform the required functions for your facility.

5. Bariatric Examination Beds

Bariatric examination beds are designed to provide additional patient support for those over 500 pounds. Built as heavy-duty structures, bariatric exam examination beds are strong and stable, and they make it easier for practitioners to transition, adjust, or lift overweight patients.

6. Pediatric Exam examination beds

If you work in a pediatric care facility, pediatric exam examination beds are exactly what you and your patients need. These examination beds are sized appropriately for children of various ages and are, therefore, smaller in size and taller in height.

Pediatric exam examination beds truly keep patients in mind, as they’re designed with fun art and bright color options to help children feel at ease when visiting the doctor.

Most pediatric exam examination beds come with digital scales, among other features, to simplify the process of weighing young children, toddlers, and babies.

7. Operating Examination Beds

Operating examination beds also known as surgical examination beds, c-arm examination beds, or operation examination beds, are for patients to lie on during surgical procedures. While you can have a stationary operating table, mobile operating examination beds were designed with casters to conveniently move patients from room to room.

8. Imaging Examination Beds

Imaging examination beds are procedure examination beds specifically designed for imaging procedures like radiology, ultrasound, CT scans, MRIs, and even surgery. Imaging examination beds are available with a range of accessories, like a c-arm or specialized positioning for urology, surgery, or an ultrasound.

Having additional accessories helps to make these procedures even more comfortable and effective for both patients and healthcare professionals. To ensure easy use and durability, these examination beds are often constructed with carbon fiber top surfaces.

9. Tilt Examination Beds

Tilt examination beds allow for special tilt table tests to take place, which help doctors identify any unknown causes of syncope.If your work requires tilting patients to provide a diagnosis, tilt examination beds are the best for your practice.

10. Specialty Examination Beds

Specialty examination beds are exam examination beds that cater to the specific needs of specialty practices. For example, mat examination beds, like the Clinton Upholstered Mat Platform, are designed for athletic centers, massage therapy facilities, rehabilitation clinics, and more.

While there are 10 different types of exam tables, they were all designed for one unifying purpose: to maximize the ease of accessing patients for the comfortable treatment of patients.

All kinds of accidents will inevitably occur in life, and the safety of children is the concern of every parent. When a child is accidentally injured, many parents will be overwhelmed and often delay a lot of time. Many parents also blamed themselves for not understanding first aid knowledge and preparing the Home First Aid Kit Box, which aggravated the injury. Therefore, it is necessary to take first aid measures for children in emergency situations in specific situations.

1) In the first case, when the child falls and is injured, if there is no open wound, local cold compresses can be used to reduce the symptoms of swelling and pain. After the acute phase has passed, hot compresses can be used to accelerate the absorption of subcutaneous congestion; if there are open wounds , To thoroughly disinfect the wound, the child is more sensitive to pain, we can use a mild disinfectant for disinfection, mild symptoms can be treated by themselves, and the dressing should be changed regularly. For deep wounds or obvious bleeding, it is necessary to go to the hospital as soon as possible, debridement by a specialist, and suture if necessary.

2) In the second case, when the child has difficulty breathing, whether it is asthma, suffocation, or severe lung disease, immediate emergency measures should be taken. Parents can first observe their children's breathing. First, listen to the sound. Difficulty breathing can be diagnosed if a child makes a "snoring" or "snoring" sound. You can also watch your child's lips turn purple. Indicates that the child has difficulty breathing and lacks oxygen. At this time, we can use a simple auxiliary respirator to help the child breathe outside. If the situation is really urgent and the child's condition is not relieved after some methods, it is best to seek professional medical help.

3) The third situation is unexpected situations such as fractures. When a child accidentally falls or falls from a height, if you are not sure whether your child's bone is broken, you can tell by the following three characteristics: whether there is pain, whether there is swelling or deformity (such as a prominent lump or a sagging arm), if In the above situation, it can be fixed with a simple fracture fixation splint first, without additional steps such as applying medicine, and immediately sent to the hospital after simple fixation.

4) Many children's wounds can be treated at home, but the child needs to be taken to the emergency room immediately if any of the following occurs:

• Length greater than one inch

• Width greater than one quarter inch

• There are cracks and uneven wound edges

• Very deep to see subcutaneous tissue such as bone or tendons

• Located anywhere on the eyes or on the head or neck (looks terrible and may require cosmetic surgery)

5) Electric shock

When children plug their hands into an electrical outlet or chew on the wires on an appliance, they can get electrocuted and burn. Electric current can burn not only the surface of the skin, but also internal burns as it conducts through body tissue. Burns from electrocution, even if they appear small on the surface, can cause serious internal injury to a child. The flow of electricity through the body can also cause abnormalities in the heart. So after an electric shock, you should take your child to the emergency room.

6) Severe allergic reaction

Allergic reactions to food, medicines, and insect bites can have disastrous consequences and can affect a child's entire bodily function. If you develop severe life-threatening symptoms (including: shortness of breath, difficulty, rapid pulse, swelling of lips and tongue, and loss of consciousness), you should go to the emergency room right away. Doctors in the emergency department will take immediate steps to address your child's breathing problems. Mild reactions such as measles can be treated on their own with home pharmacy antihistamines, but talk to your doctor first.

7) Tooth loss

Both deciduous and permanent teeth can be knocked out and then replanted. The key is to go to the hospital in time for treatment. Put the tooth in a glass of milk (or have the child spit into the glass and put the tooth in) before going to the hospital. Do not rinse the teeth or touch the roots. If teeth come out of the gums within 30 minutes, there is a good chance they will grow back. Even baby teeth are worth protecting, making sure each one is on the gums and occupies a good place for future permanent teeth.

In conclusion, there are many cases of accidental injury to children. As a parent, in addition to basic first aid knowledge, you must have some Home First Aid Kit Boxes at home for emergencies.

As the world's healthcare industry continues to innovate and evolve, there is a growing variety of assistive devices for the elderly and those with limited mobility. And the most popular and cost-effective products in the world should have a place for electric wheelchairs.

Electric wheelchairs are transformed and upgraded from traditional manual wheelchairs by superimposing high-performance power drives, intelligent control devices, batteries and other components.

The new generation of intelligent wheelchair, with a manually operated intelligent controller, can drive the wheelchair to complete the functions of forward, backward, steering, standing and lying down. It is a high-tech combination of modern precision machinery, intelligent numerical control, engineering mechanics and other fields. Technology products.

The fundamental difference with traditional electric scooters, battery-powered vehicles and bicycles is that electric wheelchairs have intelligent control controllers. Depending on the operation method, there are rocker type controllers, and controllers with various switches, such as head or blowing suction systems. The latter is mainly used for severely disabled people with upper and lower limb disabilities. Today, electric wheelchairs have become indispensable mobility tools for the elderly and disabled people with reduced mobility. They are suitable for a wide range of subjects. As long as the user has clear consciousness and normal cognitive ability, using a power wheelchair is a good choice, but requires a certain amount of space to move around.

There are a wide variety of wheelchairs on the market, which can be divided into aluminum alloy, light material and steel by material.

Electric wheelchairs can be divided into lead-acid battery-driven and aluminum battery-driven electric wheelchairs by battery.

Electric wheelchairs can be divided into general wheelchairs and special wheelchairs according to the type of use. Special wheelchairs can be divided into leisure sports wheelchairs, electric wheelchairs, stair climbing wheelchairs, etc., which are designed according to different needs of users.

Outdoor Electric wheelchairs have the following advantages.

1. Wide audience. Compared with traditional wheelchairs, the powerful functions of electric wheelchairs are not only suitable for the old and frail, but also for patients with severe disabilities. Stability, long-lasting power and adjustable speed are the unique advantages of electric wheelchairs.

2. Convenience. Traditional hand-pulled wheelchairs must be pushed and pulled by human power. If there is no one around to take care of it, you will have to push the wheels yourself. Electric wheelchairs are different. As long as it is fully charged, it can be easily operated without the need for family members to accompany you throughout the whole process.

3. Environmental protection. Electric wheelchairs use electric start, which is more environmentally friendly and easier to use than manual wheelchairs.

4. Safety. The production technology of electric wheelchairs is becoming more and more mature, and the braking equipment on the vehicle can only be produced after being tested and qualified by professionals for many times. The chances of losing control of the electric wheelchair are close to zero.

5. Use electric wheelchairs to enhance self-care. Using a power wheelchair, you can consider performing daily activities such as grocery shopping, cooking and ventilation. One person plus a power wheelchair can basically do what ordinary people can do. Such training can be very helpful to the physical and mental state of patients with limited mobility. Allowing patients to participate in simple activities in their daily lives, rather than lying in bed every day and needing help or pushing a wheelchair wherever they want to go, also helps them find joy in life and gain a sense of accomplishment. This training also helps with their re-socialization after recovery.

The following details should be noted when using outdoor electric wheelchair

1. Electromagnetic brake: Only with electricity can the brake be applied, so be sure to pay attention to safety when using it.

2. tires: always pay attention to whether the tire pressure is normal. This is the most basic check operation before each use.

3. Seat cover and backrest: Wash the seat cover and leather backrest with warm water and diluted soapy water to extend the service life of the electric wheelchair.

4. Lubrication and general maintenance: Use lubricants frequently to maintain the wheelchair, but do not use too much to avoid oil stains on the floor. If the frequency of use is high, you need to check the screws and screws frequently to make sure they are secure.

5. Normally, please wipe the body with water, avoid placing the electric wheelchair in a humid place and avoid knocking the controller, especially the rocker; when handling the electric wheelchair, please protect the controller strictly, and when the controller is contaminated by food or drink, please clean it immediately and wipe it with a diluted cleaning solution with a cloth, avoid using cleaning agents containing alcohol or other ingredients.

The above is the basic introduction to the product electric wheelchair.
