Description

Technical Field

[0001] This utility model belongs to the field of bedding technology, and more specifically, it relates to a multifunctional limb positioning pillow. Background Technology

[0002] Proper positioning, also known as antispastic positioning, is an important early measure in treating spasticity. There are three types of proper positioning: the unaffected lateral decubitus position, the affected lateral decubitus position, and the supine position. Each position requires different management tools. Traditional proper positioning typically uses ordinary pillows or cushions, stacking several together to support the limb requiring the desired position. This method uses simple, often square, pillows or cushions that are poorly molded, resulting in short-term maintenance of the position and poor joint stability, thus affecting the patient's positioning and reducing treatment effectiveness. Improper placement or duration of limb positioning can negatively impact the effectiveness of postural therapy. Therefore, caregivers need to learn how to position patients' limbs and how often to change positions, resulting in low applicability. Furthermore, while proper limb positioning mats have emerged, most are single-function and require different tools for different positions (e.g., different mats for the healthy side-lying position and the affected side-lying position), making them inconvenient to use. Caregivers also need to manually check the accuracy of limb positioning and the timing of changes, further reducing the effectiveness of postural therapy. Overall, these methods suffer from limited functionality, poor therapeutic effects, and low applicability. Utility Model Content

[0028] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "upper" and "lower" used in the following description refer to the attached drawings. Figure 1 and Figure 4 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 1 and Figure 4 The direction towards the geometric center of a specific component.

[0029] The most crucial concept of this utility model lies in its ability to combine and disassemble components to satisfy the different body positions required for proper limb positioning, as well as the functions of other conventional headrests, backrests, neck pillows, and lumbar pillows. Furthermore, through the pressure sensor 10 and timer 11, it has the dual functions of automatically detecting the accuracy of proper limb positioning and maintaining the position for a specific duration, ensuring good fixation and restraint of the patient's upper and lower limbs. It can be used accurately without requiring strong professional knowledge and has the advantages of being multifunctional, having good therapeutic effects, and being highly applicable.

[0030] Please refer to Figures 1 to 11 As shown, a multifunctional limb positioning pillow includes an upper limb pillow 1, a lower limb pillow 2, and a back pillow 3. The upper limb pillow 1 has an inverted right-angled trapezoidal vertical cross-section, and the back pillow 3 has a right-angled trapezoidal vertical cross-section. A first groove 4 for placing the patient's hand is formed on the upper long plane of the upper limb pillow 1. The inclined surfaces of the upper limb pillow 1 and the back pillow 3 are stacked together to form a combined pillow 5 for placing the patient's head or unaffected upper limb in a side-lying position. Connecting components are detachably connected between the two right-angled trapezoidal sides of the upper limb pillow 1 and the two right-angled trapezoidal sides of the back pillow 3. The bottom plane of the pillow 1 has an arc-shaped groove 6 for placing the patient's head; the side of the upper limb pillow 1 away from its inclined surface is detachably connected to a lumbar and neck pillow 7; one side of the lumbar and neck pillow 7 is a flat surface, and the other side is an arc-shaped convex surface 8 that matches the first groove 4; the upper end of the lower limb pillow 2 has a second groove 9 for placing the legs; the second groove 9, the inclined surface of the back pillow 3 and the first groove 4 are all embedded with pressure sensors 10; one side of the lower limb pillow 2, the upper limb pillow 1 and the back pillow 3 are all embedded with timers 11 and alarms (not shown in the figure, the same applies throughout the text).

[0031] As described above, when the patient is in a lateral decubitus position, the unaffected side is on top and the affected side is on the bottom. The lower limb of the unaffected side is placed in the second groove 9, and the upper limb of the affected side is placed in the first groove 4 on the upper limb pillow 1. The patient's back is supported by the inclined surface of the back pillow 3. When in use, the patient's back is against the inclined surface of the back pillow 3, creating a certain tilt angle to prevent the patient's back from standing upright. When the patient is in a lateral decubitus position, the affected side is on top and the unaffected side is on the bottom. The lower limb of the affected side is placed in the second groove 9. The inclined surfaces of the upper limb pillow 1 and the back pillow 3 are placed together and stacked from top to bottom to form a combination pillow 5. The first groove 4 of the stacked upper limb pillow 1 faces upward. Using the connecting component, the two sides of the stacked upper limb pillow 1 are detachably connected to the two sides of the back pillow 3. The upper limb of the affected side is placed in the first groove 4 of the combination pillow 5. The patient's back does not need support, or it can be rested on the lumbar and cervical pillow 7.

[0032] When using the standard headrest or backrest function, rotate the stacked and fixed combination pillow 5 so that the arc groove 6 faces upward and the first groove 4 faces downward. The arc groove 6 provides support for users who prefer a higher pillow height. When used as a backrest, rest the head against the plane with the arc groove 6 on the combination pillow 5 to achieve the functions of a standard headrest and backrest. When using the standard lumbar or neck pillow function, simply detach the lumbar and neck pillow 7 from the side of the upper limb pillow 1 away from its inclined surface, and place it under the user's lower back or neck to achieve the function of a standard lumbar or neck pillow. Alternatively, the lumbar and neck pillow 7 can be used together with the combination pillow 5 as a neck pillow and headrest. Additionally, when using the headrest function alone, to ensure the bottom of the combination pillow 5 is secure when used as a headrest... For stability, the lumbar and cervical pillow 7 can be placed in the first groove 4, and the arc-shaped convex surface 8 matches and fits the first groove 4 to fill and support it, thereby improving the stability of the bottom structure of the combination pillow 5 when it is used as a pillow. The timer 11 calculates the time the patient maintains the position, which helps to remind the patient to change the position. The pressure sensor 10 is used to detect whether the patient's upper limbs, lower limbs and back are accurately placed on the corresponding first groove 4, second groove 9 and back pillow 3, which can automatically detect the accuracy of the patient's limb positioning. When the limb position is incorrect, the pressure sensor 10 cannot detect the pressure of the patient's limbs or back, and the corresponding alarm will sound, allowing caregivers to make quick adjustments. Caregivers can use it accurately without strong professional knowledge.

[0033] Furthermore, the lower limb pillow 2 includes a front support pad 12, a middle support pad 13, and a rear support pad 14; the front face of the upper end of the front support pad 12 is flat, and a front groove 15 is formed in the middle of the rear side for placing the upper part of the lower leg or the upper part of the forearm; the upper end of the middle support pad 13 has a middle groove 16 for placing the middle part of the lower leg, the lower part of the forearm, and the palm; the front face of the upper end of the rear support pad 14 has a rear groove 17; the front groove 15, the middle groove 16, and the rear groove 17 are interconnected and together form a second groove 9, the bottom of the second groove 9 is on the same plane as the plane of the front face of the upper end of the front support pad 12; the front support pad 12, the middle support pad 13, and the rear support pad 14 are detachably connected to each other from front to back.

[0034] As described above, when lying on the affected side, the healthy side is on top and the affected side is on the bottom. The thigh and knee of the healthy limb are placed on the plane of the upper front side of the front support pad 12, the upper part of the lower leg is placed in the front groove 15, the middle part of the lower leg is placed in the middle groove 16, and the lower part of the lower leg is placed in the rear groove 17. When lying on the healthy side, the affected side is on top and the healthy side is on the bottom, and the affected lower limb is placed in the grooves as described above. When lying supine, the upper part of the affected forearm is placed in the front groove 15, and the lower part of the affected forearm and hand are placed in the middle groove 16. This allows the front support pad 12 and the rear support pad 14 to be used in different body positions.

[0035] Furthermore, the front and rear sides of the intermediate support pad 13 are provided with a first hook and loop fastener 18 on the same side, and a clearance slot 19 for placing another leg is provided at the bottom of the other side of the front and rear sides. The rear side of the front support pad 12 and the front side of the rear support pad 14 are provided with a first hook and loop fastener 20 that mates with the first hook and loop fastener 18.

[0036] As described above, when the patient is in a lateral decubitus position on the affected side, the slot 19 allows the affected limb to be placed at the knee; when the patient is in a lateral decubitus position on the unaffected side, the slot 19 allows the patient to place the bent knee of the unaffected limb, thus limiting the position of the lower limb. When the patient needs to lie on their left or right side, the first Velcro hook surface 20 on the rear side of the front support pad 12 is attached to the first Velcro rough surface 18 on the front side of the middle support pad 13, and the first Velcro rough surface 18 on the rear side of the middle support pad 13 is attached to the first Velcro hook surface 20 on the front side of the rear support pad 14, thereby achieving the desired lifting effect. The connection between the front support pad 12, the middle support pad 13, and the rear support pad 14 is stable, easy to disassemble, and convenient to store. When lying on the side in the opposite direction, simply disassemble the middle support pad 13 and rotate it 90° so that the back side of the middle support pad 13 faces forward. Then, attach the first hook and loop fastener 20 on the back side of the front support pad 12 to the original first hook and loop fastener 18 on the back side of the middle support pad 13, and attach the first hook and loop fastener 20 on the front side of the rear support pad 14 to the original first hook and loop fastener 18 on the front side of the middle support pad 13.

[0037] Furthermore, a transverse groove 21 for placing the foot or calf is provided on the rear side of the upper end face of the rear groove 17; the transverse groove 21 communicates with the rear groove 17 and is arranged in an inverted T-shape.

[0038] As can be seen from the above description, when the patient is in a lateral decubitus position or a lateral decubitus position, the transverse groove 21 is used to place the patient's foot perpendicular to the lower leg. When the patient is in a supine position, the rear support pad 14 is rotated to be parallel to the patient's straight leg and the patient's lower leg is placed in the transverse groove 21, thus realizing the multi-purpose function of the rear support pad 14 and ensuring good postural treatment effect.

[0039] Furthermore, the connecting components include a connecting strap 22, a fastener 23, and a locking member 24. One end of the connecting strap 22 is fixedly connected to the right-angled trapezoidal side of the back pillow 3, and the locking member 24 is fixedly connected to the other end of the connecting strap 22. Two fasteners 23 are fixedly connected to the right-angled trapezoidal side of the upper limb pillow 1. Connecting straps 22 are also installed on both sides of the lumbar and neck pillow 7. The movable end of the connecting strap 22 is connected to the locking member 24. The fastener 23 and the locking member 24 are detachably connected. The locking member 24 is a second Velcro hook or female buckle, and the fastener 23 is a second Velcro loop or female buckle.

[0040] As described above, when the upper limb pillow 1 and back pillow 3 need to be stacked, the other end of the connecting strap 22 of the back pillow 3 is moved toward one of the corresponding fixing parts 23 on the same side as the upper limb pillow 1. The locking part 24 on the connecting strap 22 of the back pillow 3 is glued or fastened to the fixing part 23, thus achieving the initial connection between the upper limb pillow 1 and the back pillow 3. When the stacked combination pillow 5 needs to be used as a head pillow, the lumbar and neck pillow 7 is first removed from the upper limb pillow 1, and then the lumbar and neck pillow 7 is placed in the first groove 4. The arc-shaped convex surface 18 of the lumbar and neck pillow 7 fits into the first groove 4. Then, the locking part 24 on the connecting strap 22 of the lumbar and neck pillow 7 is glued or fastened to the other fixing part 23 on the same side as the upper limb pillow 1, thus achieving the function of supporting the first groove 4 with the lumbar and neck pillow 7. This avoids the first groove 4 affecting the support stability of the bottom of the combination pillow 5 used as a head pillow. The whole assembly is easy to disassemble and store.

[0041] Furthermore, the upper end of the upper limb pillow 1 is connected to a first airbag 25 on the side away from its right angle on the long plane of the upper end, which is used to prevent the arm of the patient in the affected side lying position from falling off. The first airbag 25 is provided with a first inflation port 26 on one side.

[0042] As described above, when the patient is in a lateral decubitus position with the affected side down, the affected arm is initially restricted by the first groove 4. An external air pump is used to inflate the first air bag 25 through the first inflation port 26. The inflated first air bag 25 then provides secondary restriction to the patient's affected arm, preventing the patient's upper limb from slipping out of the first groove 4. This further enhances the restriction effect of the upper limb pillow 1 on the patient's affected limb and further ensures a good therapeutic effect.

[0043] Furthermore, a second airbag 27 is connected to the middle of the inclined surface of the back pillow 3, a second inflation port 28 is provided on one side of the second airbag 27, and a placement slot 29 is provided on the inclined surface of the back pillow 3 for placing the second inflation port 28.

[0044] As can be seen from the above description, when it is necessary to adjust the support height or angle of the back pillow 3, it is only necessary to use an external air pump (Figure 28) to inflate the second air bag 27 to the required height or angle through the second inflation port 28 to achieve the function of adjusting the support height of the slope of the back pillow 3; when the back pillow 3 and the upper limb pillow 1 are stacked, in order to ensure the stability of the stack, there is no gas in the second air bag 27. In addition, by placing the second inflation port 28 in the placement channel 29, the second inflation port 28 is prevented from protruding from the slope of the back pillow 3, thereby affecting the comfort of the patient's back support.

[0045] Furthermore, the upper limb pillow 1 has a set of protruding strips 30 with a vertical cross section in the shape of an arc on both sides of its inclined surface, and the back pillow 3 has a set of arc-shaped grooves 31 on both sides of its inclined surface for placing the protruding strips 30.

[0046] As can be seen from the above description, after the upper limb pillow 1 and the back pillow 3 are stacked to form a combined pillow 5, the protrusion 30 is placed in the arc-shaped groove 6 to prevent the upper limb pillow 1 and the back pillow 3 from tilting upwards or downwards along their mating slope, thereby further improving the stability of the stacked upper limb pillow 1 and back pillow 3; when the upper limb pillow 1 is used alone, the protrusion 30 also increases the friction between the slope of the upper limb pillow 1 and the bed surface.

[0047] Furthermore, the upper limb pillow 1, lower limb pillow 2, and back pillow 3 are all made of high-density sponge.

[0048] As can be seen from the above description, by making the upper limb pillow 1, lower limb pillow 2 and back pillow 3 all made of high-density sponge, the advantages of high-density sponge, such as good support and resistance to deformation, are utilized to improve the support and service life of the upper limb pillow 1, lower limb pillow 2 and back pillow 3; and further ensure the therapeutic effect of postural therapy.

[0049] Furthermore, the back pillow 3 includes an upper back pad 32, a middle back pad 33, and a lower back pad 34. The upper and lower end faces of the middle back pad 33 are detachably connected to the lower end face of the upper back pad 32 and the upper end face of the lower back pad 34, respectively. The upper limb pillow 1 includes an upper limb pad 35, a middle limb pad 36, and a lower limb pad 37. The upper and lower end faces of the middle limb pad 36 are detachably connected to the lower end face of the upper limb pad 35 and the upper end face of the lower limb pad 37, respectively. The thickness of the middle limb pad 36 is the same as the thickness of the middle back pad 33.

[0050] As can be seen from the above description, when a patient is relatively thin (small in width) or broad (large in width) and needs to use a combination pillow 5 with a lower or higher height, the height of the combination pillow 5 can be adjusted simply by removing or removing the middle back pad 33 and the middle limb pad 36. At the same time, when the combination pillow 5 is used as a head pillow, the height of the combination pillow 5 can also be adjusted by removing or removing the middle back pad 33 and the middle limb pad 36 or the upper back pad 32, the upper limb pad 35, the middle back pad 33 and the middle limb pad 36, so as to meet the needs of users who prefer pillows of different heights.

[0053] The inclined surfaces of the upper limb pillow 1 and the back pillow 3 are stacked together to form a combination pillow 5 for placing the patient's head or unaffected upper limb in a side-lying position. The two right-angled trapezoidal sides of the upper limb pillow 1 and the two right-angled trapezoidal sides of the back pillow 3 are detachably connected to each other with connecting components. A lumbar and neck pillow 7 is detachably connected to the side of the upper limb pillow 1 away from its inclined surface. One side of the lumbar and neck pillow 7 is flat, and the other side is an arc-shaped convex surface 8 that matches the first groove 4. In this embodiment, the flat surface of the lumbar and neck pillow 7 and the side of the upper limb pillow 1 away from its inclined surface are detachably connected by Velcro (not shown in the figure). It is not limited to the Velcro connection method. Other methods that can achieve detachable connection between the flat surface of the lumbar and neck pillow 7 and the side of the upper limb pillow 1 away from the upper limb pillow 1, such as snap fasteners, buckles, or zippers, are all acceptable. The upper long plane of the upper limb pillow 1 away from its right angle is connected to a first airbag 25 to prevent the arm of the patient in a side-lying position from falling off. The first airbag 25 has a first inflation port 26 on one side.
