[0002] As people's living standards continue to improve, most people have bad eating habits, and the three high phenomena are increasing, which in turn leads to an increase in obesity and cardiovascular and cerebrovascular disease patients, as well as an increasing number of people suffering from paralysis or hemiplegia. During medical treatment, the elderly need to stay in bed for a long time for treatment and recovery, which causes physical weakness or muscle atrophy. In the recovery training and nursing process of elderly patients, due to their high age and poor health, they often need to be accompanied by nurses, and nurses are sometimes unable to accompany the elderly patients all the time. When the elderly patients need to leave the bed, due to various physical reasons, the elderly patients are prone to tipping over when walking, which in turn causes body bumps, increases the burden of treatment, and threatens the life safety of the elderly patients in severe cases. Therefore, when the elderly are hospitalized for treatment, they often need to use walking aids. However, most of the walking aids on the market are walking aids such as crutches or wheelchairs. These devices have poor protection effects and are difficult to achieve effective anti-tipping, and their safety performance needs to be improved. In addition, due to medical treatment or their own physical reasons, the elderly may have a lot of sputum. The functions of existing products are relatively single, and they cannot solve the problem of the elderly needing to spit, and their scope of application is relatively narrow.

[0003] Existing walking assistance devices, such as a walking assistance device for stable support provided by publication number CN221534695U, include a hand support and movable wheels, a support ring is fixedly connected to the top of the hand support, an elastic restraint belt is arranged in the support ring, one end of the elastic restraint belt is fixedly connected to a rotating rod, the outer wall of the rotating rod is fixedly connected to a transmission gear, a movable rack is meshed on one side of the transmission gear, a support plate is fixedly connected to the top of the movable rack, an extrusion column is fixedly connected to the top of the support plate, and the support plate is connected to the hand support through a one-way limiter; the application provides auxiliary support for elderly patients through a mechanical structure, but the device of the application requires the elderly to extend their hands into the support ring, and the elderly's wrists are restrained by structures such as racks, gears and rotating rods. Although this design can fix the device to the elderly's hands, it cannot provide effective protection when the elderly fall down, and by restraining the wrists, the elderly's user experience will be reduced, and in some cases, the elderly's hands may be injured, and the reliability is poor.

The elderly patients in the internal medicine department can hold and push the support frame body 1 to assist in walking through the rotation of the universal wheel 402 and the supporting effect of the support frame body 1. Compared with the common auxiliary device similar to the crutches, it is more convenient to use; or the patient sits on the seat board of the support frame body 1 and is pushed by medical staff.

[0035] An electric support push rod switch 403 for controlling the extension or shortening of the electric support push rod 401 is provided on the support frame body 1, i.e., at both ends of the handle. When an elderly medical patient walks on his own, or when medical staff need to stop while pushing the child, the electric support push rod switch 403 can be used to control the extension of the electric support push rod 401 to prop up the support frame body 1 and the universal wheel 402 to prevent the support frame body 1 from sliding. At the same time, when the support frame body 1 tilts at a small angle, the sensor 5 controls the extension of the electric support push rod 401 to prevent the support frame body 1 from sliding, which is beneficial to improving the supporting effect of the support frame body 1.

[0036] A method for using a multifunctional walking assist device for elderly medical patients comprises the following steps: S1. When an elderly patient in internal medicine needs to move, he or she can hold and push the support frame body 1 by himself or herself, and walk with the help of the rotation of the universal wheel 402, or the patient can sit on the seat board of the support frame body 1 and move with the help of medical staff; S2. When the sensor 5 detects that the support frame body 1 is tilted, it can drive the electric support push rod 401 to extend to enhance the support function of the support frame body 1; when the sensor 5 detects that the support frame body 1 is tilted too much, it can drive the back airbag 301 and the side airbag 303 to inflate to provide certain protection for the patient; S3, when the patient needs to spit, the cover 2021 is opened, and the sputum is spit onto the breakpoint paper, the breakpoint paper with the sputum is kneaded by the kneading mechanism 205, and the breakpoint paper is cut by the connecting rod mechanism 204 and falls into the bottom of the collector housing 201, and then the new breakpoint paper is stretched and opened from the sticky cutting plate 2032 by the connecting rod mechanism 204 for collecting subsequent sputum; S4. Before or after the patient spits, the piston push rod 2022 on the top of the cover body 2021 can be pressed to spray disinfectant into the collector housing 201 for disinfection. Practical application cases

[0037] When walking, the elderly medical patient manually holds the handle at the top of the support frame body 1, and the universal wheel 402 at the bottom enables the elderly medical patient to move by pushing, which is more labor-saving. At the same time, the patient can also sit on the seat board, and the medical staff holds the handle at the other end to push the patient to move. The cup holder 104 at the top of the support frame body 1 can be used to place the elderly medical patient's cup or other items for easy access at any time; When an elderly patient in the medical department stops, the patient or medical staff can press the electric support push rod switch 403 to extend the electric support push rod 401 and prop up the universal wheel 402 to prevent the support frame body 1 from sliding, so as to improve the support and fixing effect between the support frame body 1 and the ground, thereby providing a good support effect for the elderly patient in the medical department; When an elderly patient of internal medicine needs to spit out phlegm in the pharynx due to his own disease or treatment, he opens the cover 2021 and spits out phlegm onto the breakpoint paper opened in the collector housing 201. Then, the collector switch 2011 controls the kneading mechanism 205 to start repeatedly to knead the breakpoint paper with phlegm, and controls the connecting rod mechanism 204 to cut the breakpoint paper from the breakpoint, and re-draws out and unfolds the unused breakpoint paper for the patient to use for spitting next time; the cut paper ball falls into the bottom of the collector housing 201 for collection, so that it can be taken out and processed together; at the same time, the piston push rod 2022 located at the top of the cover 2021 can be pressed to spray disinfectant into the collector housing 201 through the nozzle 2023 for disinfection; When the sensor 5 detects that the support frame body 1 has a small tilt, it can control the electric support push rod 401 to extend and prop up the universal wheel 402 to prevent sliding. At this time, if the patient himself falls, he can try to stabilize his body by holding the handle tightly. When it is detected that the support frame body 1 has a large tilt, the sensor 5 drives the back airbag pump 302 to inflate the back airbag 301, and drives the side airbag pump 304 to inflate the side airbag 303. When an elderly patient in internal medicine falls to the sides, the side airbag 303 can provide protection for the patient's head. When the elderly patient falls forward, the back airbag 301 can provide support for the patient.
