Description
Technical Field
[0001] This utility model relates to the field of medical and nursing equipment technology, specifically a patient mobility assistance device. Background Technology
[0002] Internal medicine is a specialty of clinical medicine, serving as the foundation for almost all other clinical medical fields, and is often referred to as the "mother of medicine." It encompasses departments such as respiratory medicine, gastroenterology, cardiology, neurology, oncology, endocrinology, hematology, and infectious diseases. Post-operative care in internal medicine requires a series of nursing interventions. The quality of this care directly impacts patient safety, treatment outcomes, and recovery. Patients also need to exercise while hospitalized to maintain their health and avoid prolonged bed rest that could lead to functional decline. The service-oriented nature of nursing care dictates that medical staff must constantly coordinate with treatment needs, striving to create a suitable environment and conditions for the patient to ensure harmonious treatment and care. Therefore, it is necessary to provide a suitable nursing environment when patients are out of the hospital to prevent external factors from affecting their recovery; this is where mobility assistive devices come in.
[0003] Currently, in the use of mobile assistive devices, due to their simple structure, most of the moving wheels are fixed to the bottom of the device, which makes it difficult to place the device stably and makes it easy for the patient to slip when getting up. In addition, during the use of the device, patients have limited physical strength and need to rest intermittently, but the existing mobile assistive devices do not provide a rest seat in between, which can easily lead to excessive fatigue for the patient and reduce the efficiency of the mobile assistive device. Therefore, we propose a patient mobile assistive device. Utility Model Content

[0037] In summary, the first housing 120 and the second housing 160 provide storage space for the first moving roller 150 and the second moving roller 163, respectively. The first electric telescopic rod 130 and the second electric telescopic rod 161 can cooperate with the first base plate 140 and the second base plate 162 to extend the first moving roller 150 and the second moving roller 163 to assist in movement. After the first moving roller 150 and the second moving roller 163 are stored in the first housing 120 and the second housing 160, respectively, the patient can hold the handrail 380 and use the protective shell 100 to stand up with the help of the housing 200, the first housing 120 and the second housing 160 contacting the ground for auxiliary support. This facilitates the stable placement of the mobility assistance device, making it less likely to slip during the patient's use and making it easy to use.
[0038] In summary, by retracting the first electric telescopic rod 130 and the second electric telescopic rod 161, the first moving roller 150 and the second moving roller 163 are respectively retracted into the first housing 120 and the second housing 160, thereby driving the protective shell 100 to be stably placed. Then, the first motor 240, in conjunction with the first lead screw 250, drives the first slider 260 to move the support plate 270 to the right, driving the seat body 280 to move out of the housing 200 through the through hole 210 to provide a resting area. This makes it easier for the mobile assistive device to provide a resting seat midway, reducing the risk of patients becoming overly tired and improving the efficiency of the mobile assistive device.
[0039] In practical use, those skilled in the art first grasp the handle 380 and, with the aid of the protective shell 100, the shell 200, the first shell 120, and the second shell 160 contacting the ground for support, stand up. Then, manually operate the control panel 390 to activate the extension of the first electric telescopic rod 130 and the second electric telescopic rod 161. The power supply 310 then supplies power to the first electric telescopic rod 130 and the second electric telescopic rod 161. Next, the extension of the first electric telescopic rod 130 causes the first base plate 140 to move downwards, driving the first moving roller 150 to move out of the first shell 120. Simultaneously, the extension of the second electric telescopic rod 161 causes the second base plate 162 to move downwards, driving the second moving roller 163 to move out of the second shell 160. Then, the second motor 340 is activated, driving the second lead screw 350 to rotate. The second slider 360, in conjunction with the horizontal plate 370, moves the armrest 380 upward to a suitable height, allowing for movement exercises. When a rest is needed, the control panel 390 is manually operated to retract the first electric telescopic rod 130 and the second electric telescopic rod 161, causing the first moving roller 150 and the second moving roller 163 to retract into the first housing 120 and the second housing 160 respectively. This causes the protective shell 100 to contact the ground with the housing 200, the first housing 120, and the second housing 160. Then, the first motor 240 is activated, driving the first lead screw 250 to rotate, which in turn drives the first slider 260 to move the support plate 270 to the right until the seat body 280 is completely removed from the housing 200 through the through hole 210. Finally, the patient can sit on the cushion 290 to rest.
