How to buy the medical rollator walker correctly

The medical rollator walker is generally made of aluminum alloy and is a trigonal (front and left and right) metal frame. It is light in weight and can be well protected by patients, some with casters. The general walker can support the weight to facilitate standing and walking. This kind of support area is large, so the stability is also good. There are many kinds of general walkers.

Fixed type, generally used to reduce the load on one side of the lower limbs, such as lower limb injury, or when the fracture is not allowed to carry weight, both hands lift the side armrests while placing them on the ground instead of one foot, then the legs are used

Interactive type, this is generally small in size, without casters, and can be adjusted in height. When using, move forward one side first, then move the remaining side forward, so move back and forth alternately. Applicable to patients with poor standing balance and poor muscle strength of the lower limbs, the advantage is that it is convenient to go to the toilet.

There is a wheel type in front. This kind of walker is used for people with poor muscle strength in the upper limbs. It is difficult to lift the walking device on one side or the whole. At this time, the front wheel touches the ground, and the foot is lifted and the foot is pushed forward to walk.

Pilots for the elderly This type of car is different from the above three types. There are four wheels that are easy to move. Instead of holding it with your hands, you can move the forearm flat on the washer. This car is suitable for elderly people who are not walking well, but pay attention to keep the body perpendicular to the ground when using it, otherwise it will slip easily.


The armpit-supported walker is mainly walked by two armpits to support weight. There are four casters, which are the largest and are used for the upper limbs.

The unilateral walker is very stable and is suitable for patients with hemiplegia or patients who are still not stable with a four-legged cane. The disadvantage is that it is heavier than a four-legged cane.

Introduction to the type of spring machine

Spring machine is a professional manufacturer of spring and hardware products. Spring machines can be generally divided into: spring machine, torsion spring machine, universal spring machine and serpentine spring machine;

The compression spring machine is mainly used to produce compression springs, which are characterized by high efficiency and stability. The universal spring machine is divided into a cam spring machine and a camless spring machine. The cam spring machine is cheaper than the camless spring machine. The camless spring machine has multiple stations that can be freely rotated, and the price is high. The main advantage is that it is suitable for producing a variety of special shapes. spring.

The use of the torsion spring machine is relatively small. Generally, the universal spring machine can be used instead of the torsion spring machine. The torsion spring machine has low production efficiency and limited limitations.

Stainless steel door purchase notice introduction

1. The first thing to pay attention to wear resistance, and the wear resistance is related to the material of the stainless steel door. When purchasing, it is generally necessary to ask the dealer what kind of material is made, such as the difference between cast iron and steel.

2. Feel, the feel of the stainless steel door is generally determined by the spring, the quality of the spring determines the feel and service life. Some lock springs are not good because it is easy to cause the handle to sag, so it is easier to shorten the life of the stainless steel door. When you purchase, you should try the toughness of the stainless steel door spring. The feel of a good spring is very soft, not too soft or too hard.

3. Plating, in the purchase process also depends on the coating of the stainless steel door, that is, whether the handle of the stainless steel door will fade. In general, the protective layer of a good stainless steel door, that is, the coating will not be easily oxidized and worn. The plating of stainless steel door handles is related to the overall aesthetics of the living room, so this cannot be ignored.

Advantages of container houses

As the common temporary residences for construction and construction, container houses have much higher reliability and reliability than traditional movable board houses. The biggest feature of container houses is convenience.

  Container mobile homes are very convenient to transport. For some construction units, because their construction sites are often replaced, ordinary mobile homes need to be disassembled and reworked. However, if you use the container mobile home, you only need to transport it to the next site by car.

   Generally speaking, container mobile houses have relatively strong firmness. Containers are generally made of steel materials, so they have better seismic and deformation resistance.

  The process requirements of the container mobile home during processing are very strict, so the container house has a very good sealing capacity, and there will be no water leakage when it rains.

The container mobile home is easy to transport, just put it on the car and transport it to any place you want to use. If other mobile homes need to be replaced, it is necessary to disassemble them first, so that the materials in the mobile homes are easily damaged.

Film Blowing machine equipment maintenance and daily inspection

All mechanical equipment is long-term work through routine maintenance and equipment maintenance. The Film Blowing machine is no exception, so you need to learn to maintain common sense and pay attention to the maintenance of the machine.

1. It is necessary to check whether the temperature self-control is intact, whether the heating appliance is in good condition, and pay attention to adjust the heating temperature of each point in time within the index range, otherwise there may be problems.
2, need to check the traction speed, but also control the film thickness.
3. Observe and adjust the thickness of the film evenly, and the folding diameter conforms to the standard.
4. Check the air storage cylinder pressure, not too high, but there should be spare pressure.
5. Check and control the ratio of raw materials and mix well.
6. Check the raw materials for impurities. In particular, check the irons in time with a magnet.
7. Check the lubricating oil lubrication of the gearbox and air compressor cylinder.
8. Regularly check the temperature rise and mechanical transmission of each running motor.
