Description

An electric fall aid station

technical field

The invention relates to an old-age assistance machine, in particular to an electric fall-down assistance vehicle.

Background technique

In today's era, with the rapid economic growth and the continuous improvement of medical standards, the aging of the population in my country and the situation of empty-nest families are becoming more and more serious. It seriously affects the quality of life of the elderly. After a fall, it is not easy to stand up due to the decline of physical function, and it is easy to cause the elderly to fall again and cause injury in the process of standing up slowly, which brings great trouble to the elderly and their children.

In improving the quality of life of the elderly, it is particularly important to prevent the elderly from falling and to assist the elderly to stand up after a fall. Through our research on the living conditions of the elderly, we found that for the elderly who can walk normally, it is not easy to prevent falls. Most of the existing fall prevention products focus on alarming the elderly after falling, so assisting the elderly to stand up after a fall has become a The most crucial part.

According to information and market visits, falls can generally be divided into two types: traumatic falls and non-invasive falls. The difference is that traumatic falls require professional assistance, while non-invasive falls can be performed manually or mechanically. Assisted standing.

Through inquiring data and research, we found that the first step is to make the center of gravity of the fallen person off the ground, which is the basis for us to assist the elderly to stand in the later stage. Existing methods for helping people with their bodies on the ground to lift their buttocks off the ground are mainly divided into manual lifts and mechanical lifts.

Manual lifting is the most common way of supporting and dragging in our lives, but these methods are often too rigid, which is not only physically exhausting but also lacks humanistic care for those who fall. Or use auxiliary tools to lift, but need to use auxiliary tools. Although the tools are simple and easy to grasp, their effects have certain requirements on the physical fitness of the assistants. Most empty-nesters live alone or with their wives of the same age. Living together does not have such conditions for implementation.

Although the mechanical lifting method does not require too much physical strength of the assistant, most elderly people who fall and cannot stand are unable to lift their hips by themselves with the help of lower limbs. The pressure of the short net bag on the body can easily cause secondary damage to the elderly. This method has limitations for the elderly with non-standard stature or unable to control the balance of the body, and lack of protective equipment, the elderly are easily slipped from the two robotic arms.

To sum up, manual lifting is very laborious and is not suitable for empty nesters. The mechanical lifting saves time and effort, but the grasping position of the center of gravity is not reasonable enough, and the body posture is unstable during the lifting of the center of gravity. Through our investigation of mechanical lifts, we found that reliable immobilization of the hip has a great impact on assisted standing after a fall. At present, there are few supporting devices on the market that assist the elderly who fall indoors to stand, which are convenient to operate, safe and reliable. Therefore, it is very necessary to design a non-invasive fall aid device for the elderly that meets the needs of the elderly to move and live alone, makes up for the lack of design of assisted standing products for the elderly, and provides security for the elderly to live and live alone. Huge market demand and application prospects.

If you want to stand up again after a fall, you usually need to grab (support) the center of gravity and lift the center of gravity to achieve the transfer of the center of gravity and complete the re-standing after a fall.

When the elderly sit on the ground with their knees bent, the most reasonable position for the body's center of gravity to grasp should be the human body's buttocks. When using the hip support method, the center of gravity support is reliable. At the same time, the body posture is relatively easy to control, and the lifting process of the center of gravity is convenient for body balance. control. However, hip support usually requires the hips to be lifted off the ground, which is a difficult task in itself for the elderly who fall. For this reason, an electric fall-aided station car is designed, which is mainly suitable for the assisting standing work of the elderly indoors when they have a non-injurious fall. Its main features are: the grasping device completes the grasping action of the center of gravity, and the opening and closing mechanism can quickly complete the hollow support of the buttocks without the buttocks off the ground, the grasping action is ingenious and convenient, the grasping position of the center of gravity is reasonable, and the support of the center of gravity is stable and reliable. When the center of gravity is raised, the back is tilted and lifted, and the body posture is easy to control, which can effectively reduce the burden on the lumbar spine, and the process of lifting the center of gravity is stable and safe. After the lift is in place, the elderly lean forward, the soles of their feet land on the ground, and the center of gravity shifts to complete the re-standing after a fall.

The electric fall aid station adopts the hip hollow support method to evolve in this way; an armchair suitable for human sitting is sawed off with four legs. Hollow out the middle of the stool panel of the chair into a "D" shape to form a hollow form. Finally, the closed vertical sides of the "D" shape are divided into two parts to form left and right sidewalls that can be opened and closed. The rib can also be moved back and forth to adjust the grabbing size according to the posture. The "D"-shaped arc is fixed on the backrest of the chair (rear bracket) to support the rear of the buttocks, and the front of the buttocks is supported by the closed lever The same as the buttock support), the gear lever and the rear bracket support the buttocks from the front and the rear respectively, forming a hollow support for the hips (same principle as the toilet seat when people squat in the toilet). The body is leaning back, and the back is leaning back and lifting (similar to pulling the jump rope with both hands when swinging, balance the body posture).

To invent a preferred embodiment, those skilled in the art can also make changes and modifications to the above-mentioned embodiments. Therefore, the present invention is not limited to the above-mentioned specific embodiments.
