Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for assisting people with lower limb disabilities to take care of themselves. Background Art

[0002] People with lower limb disability cannot use their lower limbs and can only use their hands, which seriously affects their quality of life. Existing wheelchairs and other devices that assist with toileting all require methods such as adjusting the sitting posture, setting a device under the person to facilitate toileting, or moving the device to the top of the toilet. They do not have the ability to assist people with lower limb disability to take off and put on their pants independently, so the use of such products mostly requires the assistance of nursing staff. Summary of the invention

[0003] In order to solve the above problems, we have designed a device to assist people with lower limb disabilities to take care of themselves, so as to help people with lower limb disabilities to achieve self-care ability.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a device to assist people with lower limb disabilities to take care of themselves, including a waist and hip fixing device, a lifting device and an anti-flipping device.

[0005] Preferably, the waist and hip fixing device is an open-crotch shorts or a safety belt that can connect the thigh root (or buttocks) and the waist and can bear the weight of the human body. It is worn close to the body inside the underwear, can be quickly connected and disconnected from the lifting device, and the length of the connection with the lifting device can be adjusted.

[0006] Preferably, the lifting device includes a control device and a lifting host (electric push rod, hydraulic rod or jack, etc.). The control device is arranged at a position convenient for human operation, and the lifting host is arranged at the side or rear of the personnel, and should have the function of stopping at any time with load and maintaining the height.

[0007] Preferably, the anti-rollover device is specifically a connecting rope that connects / encircles the chest of the person and the fixed position. The connecting rope should adopt an adjustable distance / length setting, or an adjustable distance / length and elastic solution, so as to assist the person to adjust the forward and backward tilt angle of the upper body by adjusting its length and prevent the person's body from leaning forward / backward excessively.

[0008] The specific process of assisting people with lower limb disabilities to take care of themselves is that the people with lower limb disabilities wear the waist and hip fixation device close to their body, connect the waist and hip fixation device to the lifting device when necessary, fasten the anti-flip device, adjust the forward / backward tilt angle of the body, and use the lifting device to control the lifting to lift the body away. Since the force points are on the waist and hips, it does not affect the activities of the upper limbs. At this time, the upper limbs that can move independently can be used to complete operations such as putting on / off pants or going to the toilet, cleaning, etc., and the lifting device can be controlled to adjust the height or drop at any time.

[0009] The beneficial effects of the present invention are: the coordinated use of the lifting device, the waist and hip fixing device, and the anti-rollover device, and the ingenious setting of the human body force points can allow the human body to keep the upper body moving freely after being lifted off the seat, and can effectively help people with lower limb disabilities to achieve completely independent taking off / putting on pants, going to the toilet, and cleaning the lower body without relying on caregivers, thereby achieving more self-care behaviors and enhancing the self-care ability of people with lower limb disabilities.
