Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation therapy technology, specifically a portable rehabilitation patient positioning aid. Background Technology
[0002] With the deepening development of biomedical research, the demand for portability and functionality in rehabilitation assistive devices is becoming increasingly prominent. Patient repositioning is a crucial step in the rehabilitation process, involving safe support and posture adjustment for individuals with limited limb movement. Current assistive devices need to balance structural stability and ease of operation to adapt to different usage scenarios. Especially in biological laboratories or home rehabilitation environments, devices must meet the requirements of lightweight, adjustable, and ergonomic design to ensure user comfort and operational efficiency. Therefore, developing a repositioning assistive device that can flexibly adapt to individual differences and is easy to carry is of great significance.
[0003] Currently, existing positional transfer assistive devices generally suffer from insufficient adjustment flexibility, complex structures, or poor portability. Traditional devices mostly employ fixed support structures, making it difficult to adapt to the height changes required by patients in different positions, and the operation process is cumbersome, increasing the burden on users. Furthermore, some devices lack sufficient consideration for user comfort; for example, the support surface is too hard or lacks antibacterial design, which may cause discomfort or hygiene problems with long-term use. These limitations restrict their widespread application in biological research or home rehabilitation scenarios, necessitating a lighter, more adjustable, and user-friendly solution. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a portable rehabilitation patient positioning aid.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] Portable rehabilitation patient positioning aids, including
[0007] The n-shaped frame consists of a horizontal beam and vertical beams symmetrically fixed at both ends of the horizontal beam;
[0008] A flexible auxiliary component, disposed on the upper surface of the horizontal beam, includes at least three parallel long plates, with adjacent long plates being rotatably connected by a hinge mechanism;
[0009] The height adjustment mechanism includes:
[0010] The gradually changing inclined groove groups are set on the side walls of each of the vertical beams. The gradually changing inclined groove groups on the same vertical beam are distributed in a figure-eight shape. The inclined grooves on a single vertical beam are distributed axially symmetrically, and the inclination angle of multiple inclined grooves on the same side of a single vertical beam decreases from the edge to the center.
[0011] A sliding shaft rotatably connected to the bottom surface of each of the aforementioned long plates, wherein the axial length of the sliding shaft decreases from the outside to the inside along the width direction of the horizontal beam;
[0012] The sliding shaft is slidably embedded in the corresponding inclined groove, and the displacement of the sliding shaft along the inclined groove causes each supporting plate to form a different height position relative to the horizontal beam.
[0013] Preferably, the hinge mechanism includes a hinge lug disposed on the side of an adjacent long plate and a rotating shaft that rotatably engages with the hinge lug. The hinge lug is integrally formed with the long plate, and the rotation angle between adjacent long plates ranges from 0° to 30°.
[0014] Preferably, in the gradually changing inclined groove group, the vertical height difference between the two ends of each inclined groove is different, and the height difference decreases from the outside to the inside along the width direction of the horizontal beam.
[0015] Preferably, the upper surface of the long board is provided with a memory foam padding layer, the memory foam padding layer is covered with a waterproof and antibacterial fabric, and the edge of the long board is provided with an arc-shaped transition chamfer, and the long board is embedded with reinforcing ribs.
[0016] Preferably, an electric push rod is provided on the outer side of the vertical beam, and the telescopic end of the electric push rod is connected to the outermost sliding shaft.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model utilizes a gradually increasing inclined groove assembly (with the tilt angle and height difference decreasing from the outside to the inside) in conjunction with an adaptable sliding shaft to enable the outer long plate to achieve a large-scale lifting and lowering, and the inner side to achieve a small-scale adjustment, forming an ergonomic height gradient (such as the back being higher than the waist, and the waist being higher than the legs), meeting the support needs of different body parts and improving the safety of body position transfer.
[0019] 2. This utility model uses a hinged design of at least three long plates, which can rotate flexibly with the patient's body position to form a support surface that conforms to the curve of the human body. It is suitable for situations where the shoulders and sides turn over more when the body turns over, while the middle of the body turns over less, thus solving the problem that traditional fixed structures are difficult to adapt to different body positions.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0026] Example
[0027] like Figure 1 As shown, the portable rehabilitation patient positioning aid includes an n-shaped frame 1, which consists of a horizontal beam 2 and vertical beams 3 symmetrically fixed at both ends of the horizontal beam 2. The n-shaped frame 1 is made of lightweight, high-strength aluminum alloy and is integrally welded, making it easy for a single person to carry while taking into account both structural stability and portability.
[0028] Preferred, such as Figure 2 As shown, the flexible auxiliary component is set on the upper surface of the horizontal beam 2, including at least three parallel long plates 4. In this embodiment, seven long plates 4 are used. The middle long plate 4 is placed in the middle of the horizontal beam 2 and fixed on it by fastening bolts. The long plates 4 on both sides can be moved to adapt to the support needs of the human torso and limbs.
[0029] Adjacent long plates 4 are rotatably connected by a hinge mechanism. The hinge mechanism includes a hinge lug 7 located on the side of the adjacent long plates 4 and a rotating shaft 8 that rotatably engages with the hinge lug 7. The hinge lug 7 and the long plate 4 are integrally injection molded from ABS engineering plastic to ensure connection strength.
[0030] The rotation angle between adjacent long boards 4 is 0°~30°. This angle design can accommodate the patient's positional changes from lying flat (0°, long board 4 is flat) to turning to the side (15°~30°, long board 4 rotates with the turning curve), avoiding the pressure of rigid support on the limbs.
[0031] The height adjustment mechanism includes:
[0032] The gradually changing inclined groove groups are set on the side walls of each vertical beam 3. The gradually changing inclined groove groups on the same vertical beam 3 are distributed in a figure-eight shape. The inclined grooves 5 on a single vertical beam 3 are distributed axially symmetrically. The inclination angle of multiple inclined grooves 5 on the same side of a single vertical beam 3 decreases from the edge to the center. For example, the inclination angle of the outermost inclined groove 5 is 30°, and the inclination angle of the middle inclined groove 5 is 15°.
[0033] In the gradient inclined chute group, the vertical height difference between the two ends of each inclined chute 5 is different, and the height difference decreases from the outside to the inside along the width direction of the horizontal beam 2. For example, the height difference between the two ends of the outer inclined chute 5 is 15cm and that of the inner one is 5cm. Through the gradient design of the height difference, the outer long plate 4 can achieve a larger range of lifting and lowering, while the inner long plate 4 has a smaller range of lifting and lowering, which is suitable for situations where the shoulders and sides of the body have a large range of turning over when the human body turns over, while the middle of the body has a small range of turning over.
[0034] The sliding shaft 6 is rotatably connected to the bottom surface of each long plate 4. The axial length of the sliding shaft 6 decreases from the outside to the inside along the width direction of the horizontal beam 2. For example, the outer sliding shaft 6 is 10cm long and the inner sliding shaft 6 is 6cm long. It can be precisely embedded in the inclined groove 5 at the corresponding position to avoid interference between adjacent sliding shafts 6 during sliding. Since the bottom and top positions of different inclined grooves 5 are different, the total length of the sliding shaft 6 is also different, and the sliding distance of the sliding shaft 6 is also different. The sliding distance of the sliding shaft 6 located at the edge is greater than that of the sliding shaft 6 located in the middle.
[0035] An electric push rod is provided on the outside of the vertical beam 3. The telescopic end of the electric push rod is connected to the outermost sliding shaft 6, and the sliding direction of the telescopic end of the electric push rod is parallel to the outermost inclined groove 5. By telescopically extending the electric push rod, the outermost sliding shaft 6 can be driven to slide along the inclined groove 5. And through the hinge linkage between the long plates 4, the other sliding shafts 6 can be driven to slide synchronously, so as to realize automated height adjustment and reduce the intensity of manual operation.
[0036] The sliding shaft 6 is slidably embedded in the corresponding inclined groove 5. Through the displacement of the sliding shaft 6 along the inclined groove 5, each supporting long plate 4 forms a different height position relative to the horizontal beam 2, thereby adapting to the patient's position transfer scenario from lying down to turning over to different degrees.
[0037] Preferred, such as Figure 3 As shown, the upper surface of the long board 4 is provided with a memory foam padding layer 9. The memory foam padding layer 9 has a density of 40D and has slow rebound characteristics. It can automatically conform to the body curve according to the patient's weight and distribute pressure.
[0038] The memory foam padding layer 9 is covered with a waterproof and antibacterial fabric 10, which is made of materials treated with silver ion antibacterial agents, such as PVC coated cloth, with a waterproof rating of IP65, making it easy to clean and disinfect, and reducing hygiene risks during long-term use.
[0039] Furthermore, the edge of the long board 4 is provided with an arc-shaped transition chamfer 11 to avoid the sharp edges scratching the patient's skin. The long board 4 is embedded with reinforcing ribs 12, which can increase the load-bearing capacity of a single long board 4 to 50kg, meeting the needs of adult users.
[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
