Abstract

The utility model relates to a sitting and standing auxiliary device, which is driven by a front electric push rod and a rear electric push rod to realize longitudinal lifting movement; the adjustable speed motor drives the motor gear to rotate, the motor gear is transmitted to the meshing gears on the two sides of the adjustable speed motor through the shaft, and the racks meshed with the meshing gears are further driven to realize transverse telescopic motion. The device is simple in structure, low in manufacturing cost, convenient and fast to move, simple to operate and capable of greatly reducing the working strength of nursing staff. The device not only can assist daily sitting and standing and like the lavatory, also can be used to the supplementary walking, for example helps the patient of rehabilitation to carry out walking training.

Description

Sit upright auxiliary device

Technical Field

The utility model belongs to the field of living facilities for assisting disabled persons and patients, and particularly relates to a sitting and standing assisting device.

Background

The aging of the population has become a major social problem worldwide. China has 1.6 billion old people aged 60 years and older, accounts for 23% of the world old people, and continues to grow at a fast speed. In addition, about 6 million of various disabled people exist in China, and account for about 5% of the general population of China. Elderly, disabled and post-operative infirm patients often face challenges when sitting and rising, particularly when using the toilet, because of their own debilitating physical function. The number of the people is large, the nursing cost is high and the labor intensity is high. Therefore, the market is in need of a device which can assist the user to complete the sitting and standing actions, reduce the workload of nursing staff, and is convenient and fast to move and simple to operate.

SUMMERY OF THE UTILITY MODEL

In view of the above technical problems, the present invention provides a device for assisting a caregiver to assist a patient or an old person in performing a sitting and rising movement.

The utility model provides a sit upright auxiliary device, its characterized in that includes preceding position electric putter 3, back position electric putter 4, adjustable speed motor 8, motor gear 9, axle 10, meshing gear 11 and rack 12. Two groups of front position electric push rods 3 and two groups of rear position electric push rods 4 which are fixed on the base 2 are driven to realize longitudinal lifting movement; the adjustable speed motor 8 drives the motor gear 9 to rotate, and is transmitted to the meshing gears 11 on the two sides of the adjustable speed motor through the shaft 10, and the racks 12 meshed with the meshing gears 11 are further driven to realize transverse telescopic motion.

The front electric push rod 3, the rear electric push rod 4 and the speed-adjustable motor 8 are connected with the single chip microcomputer through driving, the force application working curve of the device is calculated by combining the gravity center change curve of a human body in the sitting and standing processes, and a program is compiled and input into the single chip microcomputer, so that the automatic control of the device is realized.

Further, a motor cover 7 is arranged on the speed-adjustable motor 8, the motor gear 9 and the shaft 10.

Furthermore, two groups of meshing gears 11 and racks 12 are provided with telescopic arm covers 6.

Furthermore, the end of the telescopic arm cover 6 is provided with a concave underarm support 5.

Further, the material of the underarm support 5 may be a hard sponge or foam.

Further, four universal wheels 1 capable of braking are arranged below the base 2.

Further, the total length of the armpit supporting pieces 5 is 20-35cm, and the length of the rack 12 is 90-110 cm.

The device is pushed to a destination by a nursing staff, and the nursing staff lifts the armpit supporting piece 5 to the armpit of a patient or an old man through the control of the control system, so that the patient or the old man is assisted to complete the actions of sitting and getting up.

The device is simple and compact in structure, low in manufacturing cost, convenient and fast to move, simple to operate and capable of greatly reducing the working strength of nursing staff. The device not only can assist daily sitting and standing and like the lavatory, also can be used to the supplementary walking, for example helps the patient of rehabilitation to carry out walking training.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

in the drawings of the present application: the universal wheel can brake 1, base 2, preceding position electric putter 3, back position electric putter 4, armpit support piece 5, flexible arm shroud 6, motor cover 7, adjustable speed motor 8, motor gear 9, axle 10, meshing gear 11, rack 12.

Example 1

As shown in fig. 1-2, the device of the present invention is driven by a front electric push rod 3 and a rear electric push rod 4 fixed on a base 2 to realize longitudinal lifting movement; the adjustable speed motor 8 drives the motor gear 9 to rotate, and is transmitted to the meshing gears 11 on the two sides of the device through the shaft 10, and the racks 12 meshed with the meshing gears 11 are further driven to realize transverse telescopic motion. The motor cover 7 and the two groups of telescopic arm covers 6 can protect the motor, the gear and the rack in the device. The end of the telescopic arm cover 6 is provided with a concave underarm support 5. The material of the underarm support 5 can be hard sponge or foam. The length of the underarm support 5 is 30cm, the length of the rack 12 is 90cm, and the telescopic stroke of the rack 12 is about 60 cm.

The brakable universal wheel 1 can facilitate the nursing staff to push the device to the destination. The nursing staff lifts the armpit supporting piece 5 to the armpit of the patient or the old through the control of the control system, and then the device further assists the patient or the old to complete the actions of sitting and rising. The control system is controlled by a single chip microcomputer, the single chip microcomputer is connected with the front position electric push rod 3, the rear position electric push rod 4 and the speed-adjustable motor 8 through driving, and meanwhile, programs are compiled by referring to gravity center change curves of a human body in standing and sitting processes, so that the effect of fitting the working curve of the device and the gravity center change curve of the human body in the standing and sitting processes is achieved. The single chip microcomputer can be a 51-series AT89C52 single chip microcomputer.
