Description
Wheelchair mobility and walking assistance devices
[0001] The present invention relates to a device for assisting movement and walking of a patient, and more particularly, to a device for assisting movement and walking of a patient that can move a patient with difficulty in moving by sitting in a seat with small movements.
[0002] In general, patients with limited mobility require a wheelchair or other mobility aid to move around for physiological needs, treatment, or walking.
[0003] In particular, in the case of severely ill patients who have very difficult movements, getting on and off a wheelchair or moving to the bathroom to urinate or defecate relies entirely on the weight of the patient's body on a guardian or helper, requiring a lot of effort from the guardian or helper.
[0004] Korean Patent Publication No. 2024-0072493 discloses an upper body lift wheelchair device for transporting a patient. The disclosed upper body lift wheelchair device includes a movable member, a pillar frame member that is arranged vertically while connected to the movable member and has a pattern that can move through the movable member, and a suspension member that has one end of its body supported toward the pillar frame member and the other end of its body extended horizontally away from the pillar frame member so as to fix and support the upper body of a patient positioned along the longitudinal direction of the pillar frame member.
[0005] These conventional upper body lift wheelchair devices for patient transport cannot move the center of gravity of the patient's upper body, so they are relatively limited in the patient's movement.
[0006] Furthermore, Republic of Korea Patent Publication No. 2024-0163935 discloses a weight-measuring transfer assistance device. The disclosed assistance device comprises a variable fixing member and a chest support member connected to a transfer rotation frame.
[0007] Since the above-mentioned transport assistance device does not have a seat, it is difficult to smoothly move the patient.
[0008] Korean Patent No. 10-0782528 discloses a patient transfer device, and Korean Patent No. 10-2492868 discloses a patient transfer assistance device. Korean Patent Publication No. 10-2007-0098777 discloses a wheelchair that is easy to get on and off. And Korean Patent Publication No. 10-2020-0057977 discloses a wheelchair with a boarding function. The disclosed wheelchairs include a main seating section; and an auxiliary seating section that is mounted to move up and down and forward and backward from the main seating section and enters and exits the upper portion of the vehicle seat.
[0009] The posted wheelchair is equipped with an auxiliary seating section that can be moved up, down, forward, and backward from the main seating section, but a patient with limited mobility needs the assistance of an assistant as before to sit on the auxiliary seating section.
[0010] In particular, when a patient uses a wheelchair to move from the bed to the toilet to urinate or defecate, there is the difficulty of having to move the patient from the wheelchair to the toilet after moving a short distance.
[0011] The present invention is intended to solve the above-described problems, and the purpose of the present invention is to provide a device for assisting movement and walking of a patient, which allows a patient with difficulty in moving to sit on a seat with small movements, and to easily move the patient to a bed, toilet, wheelchair, etc. by raising or lowering the seat or rotating the upper body support while supporting the upper body on the upper body support.
[0012] Another purpose of the present invention is to provide a patient movement and walking assistance device that can assist a patient with walking difficulties in walking to improve lower extremity muscle strength.

[0039] Embodiments of a wheelchair-bound and walking assistance device according to the present invention are shown in FIGS. 1 to 8.
[0040] Referring to FIGS. 1 to 4, a patient moving and walking assistance device (10) according to the present invention comprises a main frame (12) on which wheels (11) for movement are installed, a main post (17) installed on the main frame (12), and an elevating member (20) that slides and is elevated on the main post (17). An axle (31) of an upper body support member (30) that can selectively support the upper body and armpit of a patient (200) is rotatably installed on the upper end of the elevating member (20), and an angle adjusting member (40) for adjusting the angle of the upper body support member (30) with respect to the elevating member (20) is installed on this installation portion.
[0041] The main post (17) above is provided with a seat (50) on which a patient can sit, and the main frame (12) and the lifting member (20) are provided with an actuator (60) for raising and lowering the lifting member (20). The actuator (60) and the main post (17) may be covered by a cover (18).
[0042] The moving and walking assistance device according to the present invention, configured as described above, is described in more detail by component as follows.
[0043] The main frame (12) has wheels (11) installed on the lower surface, first and second members (13) (14) in the shape of bars having a predetermined length, and a subframe (15) connecting the first and second members (13) (14). The first and second members (13) (14) are spaced apart at a predetermined interval so that a patient who can move can practice standing up. To this end, the subframe (15) installed between the first and second members (13) (14) is installed to have as narrow a width as possible in the central portion so that no indirect interference occurs during walking. In addition, a footrest (16) is installed on the upper surface of the front end side of the first and second members (13) (14) so that a patient (200) who sits on a seat (50) or supports his upper body on an upper body support member (30) can place his feet.
[0044] The main post (17) installed on the above subframe (15) can support the lifting member (20) in a sliding manner, and a hollow portion that slides so that the lifting member (20) can be pulled out or pulled in is installed in the longitudinal direction. The main post (17) can be installed in an inclined direction on the subframe (15).
[0045] However, the main post (17) is not limited thereto, and may be structured so as to support the lifting member (20) in a manner that it can be lifted and lowered, and also support the load of the upper body support member (30). For example, the lifting member may be formed of a plurality of guide rods that are installed so as to be slidable.
[0046] The shaft (31) of the upper body support member (30) is rotatably hinged to the end of the above-mentioned lifting member (20), and the angle of the upper body support member (30) with respect to the lifting member (20), i.e., the rotation angle of the shaft (31), is adjusted by the angle adjustment member (40).
[0047] The upper body support member (30) in which the shaft member (31) is rotatably installed on the above-mentioned lifting member (20) is provided with support frames (33) extending from each side of the shaft member (31), and a handle member (32) is formed at the end side of the support frame (33). The handle member (32) can be formed by connecting the ends of the support frames (33) extending from both ends of the shaft member (31).
[0048] The above support frame (33) has a structure that is banded with a predetermined curvature to increase the adhesion of the upper body of the patient, i.e., the stomach and chest area, and to stably support it, and an upper body support pad (34) is installed on this support frame (33).
[0049] And, on the support frames (33) on both sides, armpit support parts (35) are installed that can support the armpit areas on both sides of the patient supported by the upper body support parts (30).
[0050] The above angle adjustment member (40) has a cylindrical housing member (41) installed at the end of the lifting member (20), and a stopper (42) is installed on the outer surface of the housing member (41) to fix the position in which the upper body support member (30) is rotated downward, i.e., toward the footrest. This stopper (42) contacts the base side of the support frame (33) connected to both sides of the shaft member (31) when the upper body support member (30) rotates, thereby limiting the rotated position of the upper body support member (30).
[0051] The above angle adjusting member (40) is installed with a position fixing member (45) having position fixing holes (45a) installed at a predetermined interval on at least one side of the shaft member (31), and a sleeve (46) having a key groove (46a) formed in a longitudinal direction corresponding to the position fixing hole (45a) is fixedly installed on the housing member (41) corresponding thereto. In addition, a sliding fork (47) is installed on the shaft member (31) that slides along it and is guided by the key groove (46a) to be engaged with the position fixing hole (45a) and has a guide pin (47b). In addition, a rotating member (48) having a guide inclined groove (48a) formed to be engaged with the guide pin (47b) is installed on the inner shaft member (31) of the housing member (41). The above-mentioned rotary member (48) is coupled to a handle (49) for coupling and separating the fixed key (47a) of the sliding fork (47) to and from the position fixing hole (45a) by rotating the rotary member (48) relative to the shaft through a guide hole (41a) formed in the circumferential direction in the housing member (41).
[0052] The above angle adjustment unit is not limited to the above-described embodiment, and may be any structure that can rotate the upper body support unit (30) relative to the lifting member (20) and fix the rotation position at a predetermined angle.
[0053] Meanwhile, a seat (50) on which a patient can sit is rotatably installed on the rear side of the main post (17). That is, the seat (50) is rotatably installed on the main post (17) by a hinge axis (51) so that it can be unfolded to maintain a horizontal state or folded in a direction parallel to the main post (17).
[0054] And, a seat support member (52) is installed on the main post (17) corresponding to the part where the seat (50) is installed so as to be able to move forward and backward toward the lower side of the unfolded seat (50) to support the seat (50) in the unfolded state. The seat support member (52) is pulled out to the lower side of the seat (50) to support the seat (50) when the seat is unfolded so that a patient can sit on it. A position fixing means may be further provided at the installation part of the hinge axis (51) where the seat (50) is supported to fix the position of the seat (50) in the unfolded state.
[0055] The above sheet (50) is not limited to being installed on the maypost (17), and as shown in FIG. 4, it may be installed on the lifting member (20) and raised and lowered together with the lifting member (20). In this case, the sheet may be unfolded horizontally so that a patient can sit on it, as described above, or may be folded parallel to the lifting member (20).
[0056] The above actuator (60) is installed between the subframe (15) and the lifting member (20) to raise and lower the lifting member (20), and may be formed of a jack screw or a hydraulic cylinder.
[0057] When the above actuator (60) is formed of a cylinder, the cylinder body (61) may be rotatably installed on the subframe (15), and the rod (62) may be rotatably installed on the end of the lifting member (20). In addition, a lifting lever (63) for raising and lowering the rod (62) by operating the cylinder may be installed on the cylinder body (61).
[0058] Figures 5 and 6 illustrate another embodiment of a wheelchair-assisted locomotion and walking assistance device according to the present invention. In this embodiment, the same reference numerals as in the above embodiment indicate the same components.
[0059] Referring to the drawing, a pair of first and second main posts (71) (72) spaced apart from each other by a predetermined distance are installed at an angle on a main frame (12) having a wheel (11) installed on the lower surface, and an upper body support part (75) is installed on the first and second main posts (71) (72) so as to be able to rise and fall. The upper body support part (75) is provided with first and second support frames (76) (77) whose lower ends are slidably installed on the first and second main posts (71) (72). The upper ends of the first and second support frames (76) (77) can be interconnected to form a handle part (78), and an upper body support pad (78) is installed on the first and second support frames (76) (77). The first and second support frames (76)(77) above can be installed inclined at a predetermined curvature toward the front side, and armpit support parts (79) are installed on the upper sides of the first and second support frames (76)(77) to extend to both sides and support the armpits of a patient sitting on a seat.
[0060] And a sheet (50) is fixedly installed on the lower side of the first and second support frames (76)(77). It is preferable that the sheet (50) be installed on the upper side of the portion where the first and second support frames (76)(77) slide on the first and second main posts (71)(72).
[0061] Between the first and second main posts (71) and (72), an actuator (60) is installed to raise and lower the seat (50) and the upper body support part (75) installed thereon by introducing and withdrawing the first and second support frames (76) and (77) to and from the first and second main posts (71) and (72).
[0062] The first and second support frames (76) and (77) above may be further equipped with safety belts for the safety of the patient sitting on the seat (50).
[0063] Figures 7 and 8 show another embodiment of a wheelchair-bound and walking assistance device according to the present invention.
[0064] Referring to the drawings, the patient movement and walking assistance device (10) according to the present invention comprises a main frame (12) on which wheels (11) for movement are installed, first and second main posts (81) (82) installed on the main frame (12), and a seat frame (51) installed on first and second lifting members (83) (84) that are slidably installed on the first and second main posts (81) (82), respectively, and to which a seat or excrement container for moving the patient is coupled. The device comprises an lifting table (80) installed on third and fourth lifting members (85) (86) that are slidably installed on the first and second lifting members (83) (84), and an upper body support member (30) that is installed on the lifting table (80) so as to be rotatable and positionally fixed, and supports the upper body of the patient by supporting the armpit or chest on the upper side. And, armpit support parts (35) are provided on both sides of the upper body support part (30), and an angle adjustment part (not shown) may be further provided at the connection part between the lifting table (80) and the upper body support part (30).
[0065] And, it is provided with an actuator (60) installed on the main base (13) to raise and lower the lifting table (80), and a locking means (90) installed on the lifting table (80) and the seat frame (51) to raise and lower the lifting table (80) and the seat frame (51) simultaneously or raise and lower the seat frame alone. The locking means may be formed of a hook that is installed on each of the lifting table (80) and the seat frame (51) and a hook that is connected to the hook.
[0066] In addition, a height adjustment unit (95) for expanding the lifting height of the lifting table (80) may be further provided by installing the load of the actuator (60) and the lifting table (80).
[0067] In order to move a patient using the patient movement and walking assistance device according to the present invention configured as described above, as shown in FIGS. 1 to 3 and FIG. 9, the patient is seated on the edge of a bed or a wheelchair, and the seat (50) installed on the main post (17) or the lifting member (20) is inserted between the patient's legs so that the patient sits on the seat (50), and the chest and stomach of the patient are pressed against the upper body support member (30). Then, the armpit support members (35) are inserted between the armpits on both sides of the patient (200) to support them, and the feet of the patient (200) are placed on the footrest (16). At this time, the angle of the upper body support member (30) can be adjusted using the angle adjustment member (40) depending on the condition of the patient (200).
[0068] In this state, the actuator (60) is operated to raise the upper body support part (30) or the upper body support part (30) and the seat (50), thereby lifting the patient (200) and moving it to a predetermined position.
[0069] For example, in order to move the patient and have him / her sit on a toilet, bed, or another seat, an actuator is used to adjust the position of the patient's hips (200) to a height corresponding to the toilet or bed, and then the angle of the upper body support member (30) is adjusted so that the patient's weight can be concentrated on the upper body support member (30), and the seat support member (52) is retracted to rotate the seat (50) to a vertical state.
[0070] In this way, the chest and stomach area are supported by the upper body support (30), and the hips are maintained in a raised state.
[0071] In this state, the actuator (60) is used to lower the lifting member (20) so that the patient's (200) hips come close to or come into contact with the seating position, and then the upper body support member (30) is raised against the lifting member (20) so that the patient's load acts on the hip side, and the armpit support member (35) is separated from the patient's armpit to complete the movement of the patient (200).
[0072] This action can be substantially the same as that of the wheelchair-moving and walking assistance devices illustrated in FIGS. 5 and 7, respectively, to move the wheelchair.
[0073] And, in order to practice walking of a relatively healthy patient (200), as shown in Fig. 10, the seat support member (52) is moved back so that the seat (50) can vertically contact the main post (17), and the upper body support member (30) is adjusted vertically or at a predetermined angle using the angle adjustment member (40).
[0074] And, using an actuator (60), the lifting member (20) is raised so that the armpit support member (35) supports the patient's armpit or is adjusted to a height that the patient (200) can grasp with his / her hand. In this state, the patient can walk while pushing the walking assistance device in a standing state.
[0075] As described above, the patient movement and walking assistance device according to the present invention allows the patient to sit on or get off the seat with minimal movement while sitting, making it easy for the patient with difficulty in moving to move, and thus minimizing the effort of the guardian or helper in moving the patient.
[0076] While the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.
