DETAILED DESCRIPTION

[0029] The technical solutions of the present application will be further described in detail below in combination with specific embodiments.

[0030] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0031] Example 1

[0032] A multifunctional medical wheelchair, such as Figures 1-8As shown, including body weight measurement component, body weight measurement component includes chair frame 1, chair frame 1 top is provided with four sets of mounting sleeve 27, four sets of mounting sleeve 27 is installed at the four corners of chair frame 1 respectively, through the mounting sleeve 27 can be slidably installed with guide rod 28, the top end of guide rod 28 is embedded with weighing sensor 40, the top of guide rod 28 is provided with seat plate 2, seat plate 2 is attached with weighing sensor 40, the bottom of seat plate 2 is provided with a plurality of groups of symmetrically arranged fixing seat 32, through the fixing seat 32 can be rotatably installed with rotating wheel 31, the top of chair frame 1 is provided with two groups of servo motor 35, the output end of one side of servo motor 35 is connected with driving frame 34, the shape of servo motor 35 is trapezoidal, the size and position of rotating wheel 31 are adapted to driving frame 34, the bottom of chair frame 1 is symmetrically provided with two groups of connecting brackets 24, through the connecting bracket 24 is installed with a plurality of groups of moving wheels 25, the top of seat plate 2 is provided with a cushion, the cushion is provided with a heating wire, the both sides of seat plate 2 are symmetrically provided with handle 17, one side of chair frame 1 is provided with defecation assembly for defecation and body position adjusting assembly for adjusting, one side of handle 17 is provided with connecting rod 3, one end of connecting rod 3 is provided with protective sleeve 4;

[0033] In use, the moving wheel 25 is provided with four groups, two large and two small, respectively. The protective sleeve 4 is made of rubber material. Medical staff can hold the protective sleeve 4 to push the device. By pushing, the moving wheel 25 can contact the ground and rotate, thereby conveniently moving the patient. The transfer of bedridden patients can be completed conveniently and quickly. The patient sits on the seat cushion of the seat plate 2 during transfer. When the temperature is low, the seat cushion can be heated by starting the heating wire, thereby increasing the comfort of the patient. When sitting on the seat plate 2, the weight of the patient can be monitored by the weighing sensor 40. When the weight needs to be measured, the driving frame 34 can be controlled to move laterally by starting the two groups of servo motors 35. The rotating wheel 31 can rotate and fit on the slope of the driving frame 34. The rotating wheel 31 can be controlled to rotate on the slope by the lateral movement of the driving frame 34. The guide rod 28 can be lifted by moving on the slope of the trapezoidal driving frame 34. When the seat plate 2 is lifted by moving the driving frame 34, the weight of the bedridden patient will be fully borne by the seat plate 2. At this time, the weight of the patient on the seat plate 2 can be accurately measured by the weighing sensor 40 at the top of the guide rod 28, thereby conveniently and quickly measuring the weight of the bedridden patient. The problem that the existing method can only be weighed by a lifting scale and is relatively complicated is solved. The weight detection can be completed in a very small amount of time during use, which is relatively convenient and greatly saves time. The patient's daily weight monitoring can be conveniently completed during transfer. Changes in weight can be discovered in time for recording and processing. The guide rod 28 slides in the mounting sleeve 27 during lifting. The mounting sleeve 27 at the four corners of the chair frame 1 can limit the movement track of the guide rod 28 during lifting, thereby avoiding deviation. After weight monitoring, the seat plate 2 can be controlled to descend and reset by controlling the driving frame 34 to move in reverse.

[0035] In use, the guide slider 49 can be installed on the slide rail 52 to complete the installation of the collection bin 45, and the collection bin 45 is installed in a position matched with the pollution outlet. When the patient needs to defecate, the rotation shaft 42 and the eccentric wheel 43 are controlled to rotate by starting the two sets of rotary motors 44. The first connecting rod 36 is moved by the rotation of the eccentric wheel 43, and the second connecting rod 41 is pulled by the movement of the first connecting rod 36. When the second connecting rod 41 is pulled by the first connecting rod 36, the switch cover 39 is controlled to slide on the moving rail 37 to open the pollution outlet. After opening, the patient can sit on the device to normally excrete, and the excrement can fall into the collection bin 45 for collection, which can avoid the pollution caused by the excrement falling on the ground during transportation. When the excretion is completed or not in use, the first connecting rod 36 and the second connecting rod 41 are controlled to reset by continuing to rotate the eccentric wheel 43, thereby synchronously controlling the switch cover 39 to slide on the moving rail 37 to complete the combination of the two sets of switch covers 39. The pollution outlet is closed by the combination of the two sets of switch covers 39, which can prevent the spread of bacteria and the spread of bacteria.
