Description

Electric falling-down station-assisting vehicle

Technical Field

The invention relates to an old-age assistant machine, in particular to an electric falling-down stop assistant vehicle.

Background

In the modern times, the economic growth speed is fast, the medical level is also improved continuously, the situations of the aging of the population and the vacant nest of a family in China are increasingly serious, the falling phenomenon caused by the decline of the body function in the family life of the old people frequently occurs, the life quality of the old people is seriously influenced, the old people are difficult to stand due to the decline of the body function after falling, and the old people are easy to fall for two times to cause injury in the process of slowly standing up, so that great troubles are brought to the old people and children.

When improving the quality of life of the elderly, it is particularly important to prevent the elderly from falling down and to assist the elderly to stand up after falling down. According to the research and discovery on the living conditions of the old people, the old people capable of walking normally can be prevented from falling down difficultly, most of the existing fall prevention products are concentrated on alarming after the old people fall down, and therefore the old people can be assisted to re-stand after falling down to become the most critical one.

According to the study and the market visit, the falling condition can be generally divided into two types, namely an injury falling and a non-injury falling, the difference is that the injury falling needs professional personnel to help, and the non-injury falling can be assisted to stand manually or mechanically.

Through data inquiry and research, people find that the gravity center part of people in a falling state is separated from the ground firstly, and the foundation for assisting the old people to stand in the later period is provided. The existing methods for helping the body to be positioned on the ground to lift the hip off the ground are mainly divided into manual lifting and mechanical lifting.

The method of artificial lift is the most common supporting and dragging mode in our lives, but the modes are often excessively draggy, which not only consumes much physical strength, but also lacks humanistic care for the tumblers. Or the supporting is carried out by an auxiliary tool, but the auxiliary tool is needed, although the tool is simple and easy to grasp, the effect of the auxiliary tool has certain requirements on the physical quality of the assistor, and the empty-nest elderly mostly live alone or live together with old people similar to the ages and do not have the implementation conditions.

Although the mechanical lifting mode does not need to consume excessive physical strength of the assistor, the elderly who fall down and cannot stand cannot lift the hip by the aid of lower limb strength, so that the elderly are easily subjected to secondary injury by the compression of the cotton short net bag on the body in the process of assisting the assistor to turn over the body randomly or lift the body. This kind of mode has the limitation to the old person that the body shape is not standard or can't control body balance, and lacks protector, and the old person very easily slips from two arms.

In conclusion, manual lifting is very laborious and is not suitable for empty nesters. Mechanical lifting saves time and labor, but the gravity center grabbing position is not reasonable enough, and the body posture is unstable in the gravity center lifting process. By investigation of mechanical lifting we found that reliable fixation of the hip has a great influence on assisted standing after a fall. And the supporting device which is convenient to operate, safe and reliable and assists the old people who fall indoors in the existing market to stand is almost not available. Therefore, the design that a section satisfies the demand that the old person moved the life independently, remedies the design shortcoming of the supplementary product of standing of old person, and the old person non-injury fall-down that provides safety guarantee for old person's life alone helps a station device is very necessary, and has huge market demand and application prospect.

When the person falls down, the person wants to stand again, and usually needs to grasp (support) and lift the center of gravity to transfer the center of gravity, so that the person can stand again after falling down.

When the old people bend knees to sit on the ground, the most reasonable position for grabbing the gravity center of the body is the hip of the human body, when a hip supporting mode is adopted, the gravity center supporting is reliable, meanwhile, the body posture is relatively easy to control, the gravity center lifting process is convenient for body balance control. However, the hip support is usually completed after the hip is lifted off, and it is difficult to lift the fallen old person off the hip. Therefore, the electric falling-down standing-assisting vehicle is designed and mainly suitable for assisting standing work of indoor old people when the old people fall down in a non-traumatic manner. The main characteristics are as follows: the grabbing device finishes the gravity center grabbing action, the hip hollow support can be quickly finished without leaving the ground of the hip through the opening and closing mechanism, the grabbing action is ingenious and convenient, the gravity center grabbing position is reasonable, and the gravity center supporting is stable and reliable. The back adopts the hypsokinesis mode of lifting when the focus lifts, and the health gesture is easily controlled, effectively alleviates lumbar vertebrae burden, and the focus lifts the process steadily safely. After the old people are lifted in place, the body of the old people leans forward, the soles of the feet touch the ground, the center of gravity is shifted, and the old people can stand again after falling down.

The electric falling-down standing-assisting vehicle can be evolved in such a way by adopting a hip hollow supporting mode; sawing off four chair legs of an armrest chair suitable for a human body to sit flatly. The middle of the stool panel of the chair is hollowed into a D shape to form a hollow form. And finally, dividing the D-shaped closed vertical edge into two parts to form left and right flanges which can be opened and closed. The flange can also move back and forth, and the grabbing size can be adjusted according to the posture. The arc of "D" shape is fixed on the back of chair (rear portion bracket), supports the rear portion of buttock, and the anterior portion of buttock is supported by the shelves pole after the closure (the shelves pole supports and is supported by the buttock with human focus when swinging the swing the same), and shelves pole and rear portion bracket support the buttock from the front and back respectively, form the buttock and support (with the people squat when like the lavatory and sit at hollow toilet lid principle the same). The body is inclined backwards, and the back adopts a backward inclined lifting mode (the same as that of pulling and skipping ropes with two hands when swinging the swing, so that the body posture is balanced).

Preferred embodiments of the present invention, and those skilled in the art to which the present invention pertains can make variations and modifications to the above-described embodiments, and therefore, the present invention is not limited to the above-described embodiments, and any obvious improvements, substitutions, or modifications based on the present invention by those skilled in the art are within the scope of the present invention.
