DETAILED DESCRIPTION

[0063] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] The present application is further described in detail below in conjunction with the accompanying drawings.

[0065] The embodiments of the present application disclose a multifunctional transport tool and a control method.

[0066] like Figure 1As shown, a multifunctional transport tool comprises a back transport unit 1, a hip transport unit 2, a leg transport unit 3, an angle adjustment mechanism 4, a control wheel 5 and a steering wheel 6. The back transport unit 1 is used to support the patient's back; the hip transport unit 2 is used to support the patient's hips; the leg transport unit 3 is used to support the patient's legs; a plurality of angle adjustment mechanisms 4 are provided, and the plurality of angle adjustment mechanisms 4 are respectively provided between two adjacent transport units, and the angle adjustment mechanisms 4 are used to adjust the angle between two adjacent transport units; the control wheel 5 is provided at one end of the hip transport unit 2 close to the back transport unit 1, and the control wheel 5 is used for manual pushing; the steering wheel 6 is provided at one end of the hip transport unit 2 close to the leg transport unit 3.

[0067] This patent application can realize the transformation from a flatbed cart to a wheelchair. When in the flatbed cart state, the patient can lie flat on the flatbed cart to rest.

[0068] When it is necessary to convert it into a wheelchair state, it can be achieved by simply adjusting the angle between adjacent transfer units by adjusting the angle adjustment mechanism 4.

[0069] When switched to a wheelchair state, the back transfer unit 1 can support the patient's back; the hip transfer unit 2 can support the patient's hips; and the leg transfer unit 3 can support the patient's legs to achieve a stable sitting posture. At the same time, the patient can push the control wheel 5 set on the hip transfer unit 2 to achieve independent movement, and the steering wheel 6 can control the patient's movement direction.

[0070] It should be noted that the angle adjustment mechanism 4 can flexibly adjust the angle between adjacent transfer units to meet the patient's comfort needs.

[0071] When the multifunctional transport tool is not needed, the back transport unit 1, the hip transport unit 2 and the leg transport unit 3 need to be folded in sequence to realize the storage of the multifunctional transport function, thereby improving the overall space utilization, greatly saving storage space, optimizing hospital resource allocation, and solving the problem that the existing transport tools are limited in the application scenarios they can adapt to.

[0072] like Figure 1 and Figure 2As shown, the back transfer unit 1 includes a back support 11 and a back support base 12, and the back support 11 is detachably arranged on the back support base 12; the hip transfer unit 2 includes a hip support 21 and a hip support base 22, and the hip support 21 is detachably arranged on the hip support base 22; the leg transfer unit 3 includes a leg support 31 and a leg support base 32, and the leg support 31 is detachably arranged on the leg support base 32; the back support base 12, the hip support base 22 and the leg support base 32 are rotatably connected in sequence; a plurality of angle adjustment mechanisms 4 are respectively arranged between two adjacent support bases; a control wheel 5 is arranged at one end of the hip support base 22 close to the back support base 12; and a steering wheel 6 is arranged at one end of the hip support base 22 close to the leg support base 32.

[0073] Specifically, the back transfer unit 1, the hip transfer unit 2 and the leg transfer unit 3 are all rectangular in shape.

[0074] The back support 11, the hip support 21 and the leg support 31 are all elastic cushions, which can improve the comfort of the patient when using the multifunctional transport tool.

[0075] The detachable connection relationship between the back support member 11 and the back support base 12, the detachable connection relationship between the hip support member 21 and the hip support base 22, and the detachable connection relationship between the leg support member 31 and the leg support base 32 are all the same, and the detachable connection relationship between the back support member 11 and the back support base 12 is first described:

[0076] The back support member 11 and the back support base 12 can be detachably connected by Velcro, or the back support member 11 and the back support base 12 can be detachably connected by embedding, that is, a snap-in protrusion is provided at the center position of one side of the back support member 11 close to the back support base 12, and a snap-in groove cooperating with the snap-in protrusion is provided at a corresponding position of the back support base 12.

[0077] The specific implementation method of the detachable connection between the back support member 11 and the back support base 12 is not limited here, as long as the detachable effect between the back support member 11 and the back support base 12 can be achieved.

[0078] like Figure 1 , Figure 6 and Figure 7 As shown, the multifunctional transport tool includes a wheel mounting frame 8, which is arranged on the side of the hip support base 22 away from the hip support member 21; the control wheel 5 and the steering wheel 6 are both arranged on the wheel mounting frame 8, and the control wheel 5 is arranged close to the back transport unit 1 relative to the steering wheel 6.

[0079] Specifically, the wheel mounting frame 8 includes a first wheel mounting member 81 and a second wheel mounting member 82, and the first wheel mounting member 81 and the second wheel mounting member 82 are both arranged on the bottom surface of the hip support base 22 (that is, the side of the hip support base 22 away from the hip support member 21), and the first wheel mounting member 81 and the second wheel mounting member 82 are arranged at intervals.

[0080] The first wheel mounting member 81 has the same structure as the second wheel mounting member 82 . Here, the first wheel mounting member 81 is taken as an example for description. The first wheel mounting member 81 includes a wheel mounting base 811 , a first wheel connecting portion 812 and a second wheel connecting portion 813 .

[0081] The mounting base is arranged on the bottom surface of the hip support base 22, and the first wheel connection portion 812 and the second wheel connection portion 813 are respectively arranged on both sides of the mounting base, the first wheel connection portion 812 is located on the side of the hip support base 22 close to the back support base 12, and the second wheel connection portion 813 is located on the side of the hip support base 22 close to the leg support base 32.

[0082] The control wheel 5 is arranged at the end of the first wheel connecting portion 812 , and the steering wheel 6 is arranged at the end of the second wheel connecting portion 813 .

[0083] The diameter of the control wheel 5 is larger than the diameter of the steering wheel 6 , and a portion of the control wheel 5 is higher than the hip support 21 , so that the patient's hand can push the control wheel 5 to move.

[0084] It should be noted that there are two control wheels 5 and two steering wheels 6, and the second wheel mounting member 82 is also provided with a control wheel 5 and a steering wheel 6, which will not be described in detail here.

[0085] Furthermore, a third wheel mounting member 121 and an auxiliary support wheel 122 are provided on the bottom surface of the back support base 12 .

[0086] The third wheel mounting member 121 is arranged near one end of the back support base 12 away from the hip support base 22, one end of the third wheel mounting member 121 is rotatably arranged on the back support base 12, and the auxiliary support wheel 122 is arranged at the other end of the third mounting member.

[0087] When the multifunctional transport tool is in a flatbed state, the third wheel mounting member 121 and the auxiliary support wheels 122 can support the back transport unit 1 without affecting the movement of the flatbed.

[0088] When the multifunctional transport tool is switched from a flatbed state to a wheelchair state, the third wheel mounting member 121 can be folded so that the whole is against the bottom surface of the back support base 12, thereby achieving overall avoidance and storage.

[0089] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the angle adjustment mechanism 4 includes a first angle adjustment member 41, a second angle adjustment member 42 and an adjustment switch 43; the first angle adjustment member 41 and the second angle adjustment member 42 are rotatably connected, and the adjustment switch 43 is arranged on the first angle adjustment member 41, and the adjustment switch 43 is used to control the start and stop of the rotation between the first angle adjustment member 41 and the second angle adjustment member 42; the ends of the first angle adjustment member 41 and the second angle adjustment member 42 that are away from each other are respectively arranged between two adjacent supporting substrates.

[0090] Specifically, one end of the first angle adjustment member 41 is rotatably connected to one end of the second angle adjustment member 42, and the adjustment switch 43 is set at the rotatable connection between the first angle adjustment member 41 and the second angle adjustment member 42. The adjustment switch 43 can control the start and stop of the rotation between the first angle adjustment member 41 and the second angle adjustment member 42.

[0091] When it is necessary to adjust the angle between the first angle adjustment member 41 and the second angle adjustment member 42, such as switching the multifunctional transport tool from a flatbed car state to a wheelchair state, the adjustment switch 43 is adjusted to the first state, and the first angle adjustment member 41 and the second angle adjustment member can be rotated to adjust the angle.

[0092] When the angle is adjusted to a desired value, the adjustment switch 43 is switched to the second state, at which time the first angle adjustment member 41 and the second angle adjustment member 42 are locked and cannot rotate relative to each other.

[0093] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first angle adjustment member 41 includes a first angle adjustment base 411, a first angle adjustment portion 412 and a second angle adjustment portion 413; the first angle adjustment portion 412 and the second angle adjustment portion 413 are both arranged at the same end of the first angle adjustment base 411, and the first angle adjustment portion 412 and the second angle adjustment portion 413 are arranged at intervals; the second angle adjustment member 42 extends between the first angle adjustment portion 412 and the second angle adjustment portion 413; the adjustment switch 43 includes a connecting rod 431 and an adjustment control member 432; the connecting rod 431 passes through the second angle adjustment portion 413, the second angle adjustment member 42 and the first angle adjustment portion 412 in sequence, and extends from a side of the first angle adjustment portion 412 away from the first angle adjustment portion 412; the adjustment control member 432 is rotatably arranged at one end of the connecting rod 431 extending from a side of the first angle adjustment portion 412 away from the first angle adjustment portion 412, and the adjustment control member 432 is used to squeeze the first angle adjustment portion 412 below by rotating.

[0094] Specifically, to reduce stress concentration of the first angle adjustment member 41 , a side of the first angle adjustment portion 412 facing away from the second angle adjustment portion 413 is flush with a side of the first angle adjustment base 411 , and a side of the second angle adjustment portion 413 facing away from the first angle adjustment portion 412 is flush with a side of the first angle adjustment base 411 .

[0095] The first angle adjustment portion 412 and the second angle adjustment portion 413 have elastic potential energy to return to a state of being flush with the first angle adjustment base 411 .

[0096] The second angle adjustment member 42 extends between the first angle adjustment portion 412 and the second angle adjustment portion 413 .

[0097] The first angle adjustment portion 412 is provided with a first connecting hole 4122 , the second angle adjustment portion 413 is provided with a second connecting hole 4132 , the second angle adjustment member 42 is provided with a third connecting hole 4213 , and the first connecting hole 4122 , the second connecting hole 4132 and the third connecting hole 4213 are concentrically arranged.

[0098] The connecting rod 431 extends from the outer side of the second communicating hole 4132 , passes through the second communicating hole 4132 , the third communicating hole 4213 and the first communicating hole 4122 in sequence, and extends from the outer side of the first communicating hole 4122 .

[0099] The adjustment control member 432 is disposed at one end of the connecting rod 431 extending from the outer side of the first communication hole 4122 .

[0100] The adjustment control member 432 includes an adjustment portion 4321 and a pressing portion 4322. The adjustment portion 4321 is cylindrical in shape, and the pressing portion 4322 is plate-shaped. The pressing portion 4322 is disposed on the side wall of the adjustment control member 432. A rotation groove is disposed on the side wall of the adjustment portion 4321, and the end of the connecting rod 431 extends into the rotation groove and is rotatably connected to the side walls of the rotation groove.

[0101] It should be noted that the rotation axis between the connecting rod 431 and the adjusting portion 4321 is not coaxial with the central axis of the adjusting portion 4321 .

[0102] Since the rotating axis between the connecting rod 431 and the adjusting portion 4321 is not coaxial with the central axis of the adjusting portion 4321, when the adjusting portion 4321 rotates, when the rotating axis moves in a direction close to the second angle adjustment portion 413, the adjusting portion 4321 will squeeze the first angle adjustment portion 412, so that the distance between the first angle adjustment portion 412 and the second angle adjustment portion 413 will gradually decrease, and finally the first angle adjustment portion 412 and the second angle adjustment portion 413 will respectively abut and squeeze the second angle adjustment member 42, thereby achieving the purpose of fixing the angle between the two adjacent supporting bases.

[0103] When the adjusting portion 4321 is rotated in the opposite direction, the rotating axis moves in a direction away from the second angle adjusting portion 413, and the adjusting portion 4321 gradually stops squeezing the first angle adjusting portion 412, so that the distance between the first angle adjusting portion 412 and the second angle adjusting portion 413 gradually increases, and finally the first angle adjusting portion 412 and the second angle adjusting portion 413 no longer squeeze or abut against the second angle adjusting member 42, so that the angle between two adjacent supporting substrates can be freely adjusted.

[0104] To facilitate angle adjustment, the user can press or lift the pressing part 4322 to achieve forward and reverse rotation of the adjustment part 4321, where forward rotation is to achieve the movement of the rotation axis in a direction close to the second angle adjustment part 413, and reverse rotation is to achieve the movement of the rotation axis in a direction away from the second angle adjustment part 413.

[0105] Furthermore, in order to facilitate the use of the angle adjustment mechanism 4 to rotate the folding transfer unit and adjust the angle between adjacent transfer units, a coaxial linkage rod is also provided on the multifunctional transfer tool. The coaxial connecting rod 44 is arranged between the two connecting rods 431 on both sides of the same transfer unit, and the two ends of the coaxial connecting rod 44 are respectively connected to one end of the two connecting rods 431 that are away from the adjustment control part 432.

[0106] Furthermore, the second angle adjustment member 42 includes a telescopic portion 421 , a receiving portion 422 and a telescopic adjustment knob 423 .

[0107] A telescopic hole is provided at one end of the accommodating portion 422, and the telescopic portion 421 is slidably arranged in the telescopic hole. The other end of the accommodating portion 422 is arranged on the supporting base, and the other end of the telescopic portion 421 extends between the first angle adjustment portion 412 and the second angle adjustment portion 413. The third connecting hole 4213 is arranged on the telescopic portion 421.

[0108] A screw hole is provided on the surface of the accommodating portion 422 , the screw hole is connected to the telescopic hole, the telescopic adjustment knob 423 is screwed to the screw hole, and the telescopic adjustment knob 423 is used to abut against the telescopic portion 421 located in the telescopic hole to limit the position of the telescopic portion 421 .

[0109] By adjusting the length of the telescopic portion 421 that penetrates into the telescopic hole, the distance between adjacent transfer units can be adjusted, thereby being able to accommodate more patients of different heights.

[0110] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a first annular meshing tooth 4121 is provided on a side of the first angle adjustment portion 412 close to the second angle adjustment portion 413; a second annular meshing tooth 4131 is provided on a side of the second angle adjustment portion 413 close to the first angle adjustment portion 412; a third annular meshing tooth 4211 is provided on a side of the second angle adjustment member 42 close to the first angle adjustment portion 412, and the third annular meshing tooth 4211 is used to mesh with the first annular meshing tooth 4121; a fourth annular meshing tooth 4212 is provided on a side of the second angle adjustment member 42 close to the second angle adjustment portion 413, and the fourth annular meshing tooth 4212 is used to mesh with the second annular meshing tooth 4131.

[0111] Specifically, the first annular meshing tooth 4121 is arranged around the first connecting hole 4122, and the first annular meshing tooth 4121 is coaxially arranged with the first connecting hole 4122; the second annular meshing tooth 4131 is arranged around the second connecting hole 4132, and the second annular meshing tooth 4131 is coaxially arranged with the second connecting hole 4132; the third annular meshing tooth 4211 and the fourth annular meshing tooth 4212 are arranged around the third connecting hole 4213, and the third annular meshing tooth 4211 and the fourth annular meshing tooth 4212 are both coaxially arranged with the third connecting hole 4213.

[0112] When the pressing portion 4322 is pressed to make the adjusting portion 4321 rotate forward, the rotating shaft moves in the direction close to the second angle adjusting portion 413, and the adjusting portion 4321 squeezes the first angle adjusting portion 412. The distance between the first angle adjusting portion 412 and the second angle adjusting portion 413 gradually decreases, and finally the first angle adjusting portion 412 and the second angle adjusting portion 413 respectively abut and squeeze the second angle adjusting member 42. At this time, the first annular meshing teeth 4121 mesh with the third annular meshing teeth 4211, and the second annular meshing teeth 4131 mesh with the fourth annular meshing teeth 4212, thereby increasing the stability of the angle fixation between the two adjacent supporting substrates.

[0113] When the lifting and pressing portion 4322 causes the adjusting portion 4321 to rotate in the opposite direction, the rotating shaft moves in a direction away from the second angle adjusting portion 413, and the adjusting portion 4321 gradually stops squeezing the first angle adjusting portion 412, so that the distance between the first angle adjusting portion 412 and the second angle adjusting portion 413 gradually increases, and finally the first angle adjusting portion 412 and the second angle adjusting portion 413 no longer squeeze or abut against the second angle adjusting member 42, at which time the first annular meshing teeth 4121 no longer mesh with the third annular meshing teeth 4211, and the second annular meshing teeth 4131 no longer mesh with the fourth annular meshing teeth 4212, so that the angle between two adjacent supporting substrates can be freely adjusted.

[0114] like Figure 1 , Fig.11 and Fig.12As shown, the multifunctional transport tool includes a head washing assembly 7 , which is arranged at one end of the back support base 12 away from the hip support base 22 .

The accommodating barrel 72 can be installed on the head support 712 by embedding the embedding protrusion 721 into the first embedding groove 7121.

[0120] When the receiving tube is installed, the receiving barrel 72 is located below the head support 712 .

[0121] The opening size of the barrel cavity of the accommodating barrel 72 for collecting shampoo water is larger than the size of the head support 712 to prevent the shampoo water from flowing onto the ground and dirtying the ground.

[0122] It should be noted that the head support 712 is a waterproof pad with elasticity and waterproof function.

[0123] Furthermore, the shampooing assembly 7 is detachably arranged at one end of the back supporting base 12 away from the hip supporting base 22 .

[0124] The head abutting member 71 includes an insert block 713 , which is disposed at an end of the head connecting member 711 away from the head supporting member 712 .

[0125] One end of the back support base 12 away from the hip support base 22 is provided with a second embedding groove that is embedded and matched with the insertion block 713.

[0126] When the patient does not need to wash his hair, a head support member with the same width as the head support member 712 can be inserted into the second embedded groove to improve the comfort of the patient's head. When the patient needs to wash his hair, the insertion block 713 can be inserted into the second embedded groove to install the components for washing his hair. The overall T-shaped structure of the head connecting member 711 and the head support member 712 can allow as much shampooing water as possible to flow into the receiving barrel 72 below during the shampooing process.

[0127] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the hip transfer unit 2 is provided with a discharge port 221 , and a discharge bucket 222 is provided below the discharge port 221 .

[0128] Specifically, the excretion port 221 passes through the hip support 21 and the hip support base 22, and the patient can excrete excrement into the excretion bucket 222 located under the hip support base 22 through the excretion port 221, thereby providing a convenient sanitary facility for the patient.

[0129] The drainage bucket 222 is disposed below the buttocks support base 22 , and between the first wheel mounting member 81 and the second wheel mounting member 82 , and the bucket mouth of the drainage bucket 222 is concentrically disposed with the drainage port 221 .

[0134] like Figure 1 and Figure 2As shown, the multifunctional transport tool comprises a binding member 9, and a plurality of binding members 9 are provided. The plurality of binding members 9 are arranged on the transport unit, and the binding members 9 are used to fix the patient on the multifunctional transport tool, so as to enhance stability.

[0135] In this embodiment, three binding members 9 are provided, and the three binding belts are respectively provided on the back support base 12 , the hip support base 22 and the leg support base 32 .

[0136] The binding member 9 disposed on the back support base 12 is now used as an example for explanation:

[0137] The binding piece 9 is an elastic binding belt, and the binding piece 9 includes a first binding piece 9 and a second binding piece 9. One end of the first binding piece 9 is arranged on one side of the back support base 12, and one end of the second binding piece 9 is arranged on the other side of the back support base 12. The other end of the first binding piece 9 and the other end of the second binding piece 9 are respectively provided with buckles that can be connected to each other.

[0138] When the patient leans against the multifunctional transport tool, the first binding member 9 and the second binding member 9 can be buckled, so that the binding member 9 arranged on the back support base 12 can fix the patient's upper limbs on the back transport unit 1.

[0139] Furthermore, zippers are provided on both sides of the back support base 12. When the binding member 9 is not needed, the zipper can be opened and the binding member 9 can be inserted into the space inside the zipper to prevent the binding member 9 from drooping outside and causing unsightly appearance and occupying space.

[0140] Likewise, the hip support base 22 and the leg support base 32 are also provided with zippers for accommodating corresponding binding members 9 .

[0141] like Figure 1 As shown, protective rails 223 are detachably provided on both sides of the hip support base 22 and the back support base 12 to further increase the stability of the patient using the multifunctional transport tool.

[0142] When the multifunctional transport tool is converted from a flatbed car state to a wheelchair state or is stored, the guardrail 223 can be disassembled as needed.

[0143] like Figure 1 , Fig. 9 and Fig.10 As shown, an expansion piece 224 is provided on one side of the hip support base 22 , and the expansion piece 224 is used to add a dining table 225 and an infusion stand 226 .

[0144] Specifically, two expansion pieces 224 are provided, and the two expansion pieces 224 are respectively provided on the left and right sides of the buttocks support base 22 .

[0145] The expansion piece 224 includes an expansion piece 224 base and an expansion knob piece 2242. The expansion piece 224 base is provided with an insertion hole. The expansion knob piece 2242 is screwed to one side of the expansion piece 224 base, and the screwed end of the expansion knob piece 2242 can extend into the insertion hole.

[0146] The dining table 225 includes a dining table 225 body and an inserting portion 2252 . The inserting portion 2252 is disposed on the dining table 225 body, and the inserting portion 2252 is disposed perpendicularly to the dining table 225 body.

[0147] The insertion portion 2252 can be inserted into the insertion hole, and then the expansion knob 2242 is rotated so that the end of the expansion knob 2242 that is screwed in extends into the insertion hole and abuts against the outer wall of the insertion portion 2252, thereby realizing the installation of the dining table 225 on the hip transfer unit 2, and the height of the dining table 225 can be freely adjusted according to the depth of the insertion portion 2252 into the insertion hole, so as to adapt to patients of different heights.

[0148] Similarly, the infusion stand 226 can also be inserted into the insertion hole on the base of the expansion piece 224 on the other side. Similarly, by screwing the expansion knob 2242 so that the screwed-in end of the expansion knob 2242 extends into the insertion hole and presses against the outer wall of the infusion stand 226, the infusion stand 226 can be installed on the hip transfer unit 2.

[0149] The multifunctional transport tool is also provided with a braking system, which may adopt one of a hand brake system, a foot brake system, an electromagnetic brake system or an intelligent brake system.

[0150] First, the hand brake system is used as an example for explanation. Brake handles are provided on both sides of the hip support base 22. The user or the caregiver can directly hold the brake handles and pull them backwards. Through the transmission device such as the brake line, the brake block at the control wheel 5 is driven to be in close contact with the wheel, and the wheel is prevented from rotating by friction, thereby achieving braking. When the brake handle is released, the brake block is separated from the wheel by the corresponding reset spring and other devices, and the wheelchair can resume normal pushing.

[0151] like Figure 1 As shown, the multifunctional transport tool also includes a foot pedal assembly 10, and at least two foot pedal assemblies 10 are provided. At least two foot pedal assemblies 10 are arranged at one end of the leg support base 32 away from the back support base 12. The at least two foot pedal assemblies 10 are used for the patient's two feet to step on when the multifunctional transport tool is switched into a wheelchair tool.

[0152] Specifically, two footrest assemblies 10 are provided, and the two footrest assemblies 10 are arranged opposite to each other on the leg support base 32. Now, one of the footrest assemblies 10 is taken as an example for description:

[0153] The pedal assembly 10 includes a pedal mounting member 101 and a footboard 102 . One end of the pedal mounting member 101 is hingedly arranged on a side of the leg support base 32 away from the leg support member 31 . The pedal mounting member 101 can rotate left and right around the hinge point with the leg support base 32 .

[0154] The foot pedal 102 is arranged at the other end of the foot pedal mounting member 101 , and the foot pedal 102 can rotate up and down around the hinge point with the foot pedal mounting member 101 .

[0155] It should be noted that, in order to increase the stability of the pedal 102 being stepped on, the rotation angle between the pedal 102 and the pedal mounting member 101 is greater than zero degree, and the rotation angle between the pedal 102 and the pedal mounting member 101 is less than or equal to ninety degrees.

[0156] When the multifunctional transport tool is switched from a flatbed car state to a wheelchair state, the two footrest mounting parts 101 can be rotated to extend from the bottom of the leg support base 32, and then the foot pedal 102 is rotated so that the foot pedal 102 and the footrest mounting part 101 are vertically arranged, and the patient's left and right feet can step on the corresponding foot pedals 102 respectively.

[0157] like Fig.13 As shown, a control method of a multifunctional transport tool is applied to any multifunctional transport tool as described above, and the method comprises:

[0158] S100, adjusting the angles between adjacent transfer units to achieve switching of the multifunctional transfer tool from a flatbed car state to a wheelchair state.

[0159] Specifically, in the flatbed state, the angle between the back transfer unit 1 and the hip transfer unit 2, and the angle between the hip transfer unit 2 and the leg transfer unit 3 are both 180 degrees. At this time, the back support 11, the hip support 21 and the leg support 31 are located on a flat surface, and the patient can lie flat on the multifunctional transfer tool to rest. At the same time, the patient's head rests on the head support 712, and the hair washing operation can be performed after the accommodating bucket 72 is installed.

[0160] When in a wheelchair state, the angle between the back transfer unit 1 and the hip transfer unit 2 can be adjusted between 90 degrees and 180 degrees according to the patient's comfort requirements.

[0161] Similarly, the angle between the hip transfer unit 2 and the leg transfer unit 3 can be adjusted between 180 degrees and 270 degrees.

[0162] In summary, a multifunctional transport tool comprises a back transport unit 1, a hip transport unit 2, a leg transport unit 3, an angle adjustment mechanism 4, a control wheel 5 and a steering wheel 6. The back transport unit 1 is used to support the patient's back; the hip transport unit 2 is used to support the patient's hips; the leg transport unit 3 is used to support the patient's legs; the back transport unit 1, the hip transport unit 2 and the leg transport unit 3 are rotatably connected in sequence; there are multiple angle adjustment mechanisms 4, and the multiple angle adjustment mechanisms 4 are respectively arranged between two adjacent transport units, and the angle adjustment mechanisms 4 are used to adjust the angle between two adjacent transport units; the control wheel 5 is arranged at one end of the hip transport unit 2 close to the back transport unit 1, and the control wheel 5 is used for manual pushing; the steering wheel 6 is arranged at one end of the hip transport unit 2 close to the leg transport unit 3.

[0163] This patent application can realize the transformation from a flatbed cart to a wheelchair. When in the flatbed cart state, the patient can lie flat on the flatbed cart to rest.

[0164] When it is necessary to convert it into a wheelchair state, it can be achieved by simply adjusting the angle between adjacent transfer units by adjusting the angle adjustment mechanism 4.

[0165] When switched to a wheelchair state, the back transfer unit 1 can support the patient's back; the hip transfer unit 2 can support the patient's hips; and the leg transfer unit 3 can support the patient's legs to achieve a stable sitting posture. At the same time, the patient can push the control wheel 5 set on the hip transfer unit 2 to achieve independent movement, and the steering wheel 6 can control the patient's movement direction.

[0166] It should be noted that the angle adjustment mechanism 4 can flexibly adjust the angle between adjacent transfer units to meet the patient's comfort needs.

[0167] When the multifunctional transport tool is not needed, the back transport unit 1, the hip transport unit 2 and the leg transport unit 3 need to be folded in sequence to realize the storage of the multifunctional transport function, thereby improving the overall space utilization, greatly saving storage space, optimizing hospital resource allocation, and solving the problem that the existing transport tools are limited in the application scenarios they can adapt to.

[0168] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0169] It should be noted that the present invention takes a multifunctional transport tool and a control method as an example to introduce the specific structure and working principle of the present invention, but the application of the present invention is not limited to a multifunctional transport tool and a control method, and can also be applied to the production and use of other similar workpieces.

[0170] It should be understood that the present invention is not limited to the exact construction that has been described above and shown in the drawings and that various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
