Description

Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, and in particular to a multi-form variable orthopedic nursing pad. Background Technology

[0002] In orthopedic clinical nursing, various nursing pads are commonly used as assistive devices to relieve local pressure on patients, maintain treatment positioning, and improve bed rest comfort. Currently, the most widely used type is the fixed-shape pad. These pads are typically made of elastic materials such as sponge, memory foam, or gel, covered with waterproof medical fabric, and pre-molded into a specific, unchangeable geometric shape. Despite continuous material improvements, these fixed-shape pads have a fundamental, inherent defect determined by their structure: their function and shape are pre-fixed, making any adaptive adjustments during use impossible. This directly leads to the following clinical problems: One pad for one use, single function: A nursing pad of a fixed shape can only solve a single support need. For example, a wedge-shaped pad is only suitable for raising the back and cannot be used for back support or limb protection when lying on the side. In order to meet the diverse needs of patients in different positions (such as supine, lateral, semi-recumbent, and leg-raised), nursing units must be equipped with pads of various shapes, which creates a burden on storage and management.

[0003] Poor fit and imprecise support: Patients' body shapes, injuries, and comfort needs vary significantly from person to person. Fixed sizes and angles are difficult to perfectly match each patient's physiological curves, easily creating areas of unsupported or excessive pressure, affecting pressure distribution, and long-term use may increase the risk of pressure ulcers and reduce patient comfort.

[0004] The process is cumbersome and inefficient: When a patient needs to change position, nursing staff must remove the original mattress and find and replace it with a mattress of a different shape. This process not only increases the workload of nursing staff but also frequently disturbs the patient's rest, and there are potential safety risks during the movement of the patient and the replacement of the mattress.

[0005] Therefore, the existing fixed-shape orthopedic nursing pads, due to their immutable shape, create a core contradiction with the dynamic and personalized support needs in clinical nursing. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the present invention aims to solve the problem that the traditional orthopedic nursing pad has a fixed shape and cannot be adjusted, and cannot adapt to various body position requirements.

[0007] To solve the above-mentioned technical problems, this utility model provides a multi-form variable orthopedic nursing pad, including a first pad, a second pad, a third pad, and a fourth pad arranged sequentially adjacent to each other. The first pad and the second pad are connected by a first hinge, the second pad and the third pad are connected by a second hinge, and the third pad and the fourth pad are connected by a third hinge. Each hinge allows adjacent pads to rotate relative to each other around the hinge axis. By bending different hinges, the nursing pad can be converted between an unfolded form and at least two folded forms suitable for different body position support.

[0008] This invention utilizes a series design of four pads and three hinges to create a nursing pad that can actively deform into a single structure. This breaks through the limitations of traditional nursing pads with fixed shapes, allowing caregivers or patients to flexibly switch between unfolded and folded forms through simple bending operations. This enables adaptation to different body positions and significantly improves ease of use, patient comfort, and nursing efficiency.

[0009] As a preferred or optional solution, the first, second, third, and fourth pads all have wedge-shaped cross-sections, and the backs of the four pads are flush when the nursing pad is unfolded. The wedge-shaped structure of each pad facilitates their assembly into a stable three-dimensional shape. In the unfolded state, the flush backs of each pad ensure stable and flat contact with the bed surface or other supporting surfaces, preventing wobbling and providing a regular initial state for folding and deformation.

[0010] As a preferred or optional embodiment, in its unfolded state, the second hinge is located on the front side, while the first and third hinges are located on the back side. This hinge placement design allows the pad to bend more naturally in a specific direction during folding, ensuring a compact and stable structure after folding.

[0011] As a preferred or optional embodiment, in its unfolded state, the first and fourth pads are symmetrically arranged with respect to the center line of the pad's length direction, as are the second and third pads. The pad's fully symmetrical structure in its unfolded state eliminates the need to distinguish between the beginning and end or left and right directions during actual use, reducing complexity. Simultaneously, it ensures that a symmetrical and stable support structure is formed regardless of where the folding begins, enhancing the product's versatility and ease of use.

[0012] As a preferred or optional embodiment, the nursing pad has a first folded configuration, in which the back sides of the first pad block and the fourth pad block are fitted together, and the back sides of the second pad block and the third pad block are fitted together, with the overall cross-section of the nursing pad being wedge-shaped. Through a simple folding operation, it can be quickly converted into a stable wedge-shaped pad, a configuration that can be used to maintain the patient's lower limb abduction angle.

[0013] As a preferred or optional embodiment, the nursing pad has a second folded configuration. In this configuration, the backs of the second pad and the third pad are fitted together, the front of the first pad is fitted together with the front of the second pad, and the front of the fourth pad is fitted together with the front of the third pad. The overall cross-section of the nursing pad is convex. This configuration effectively supports and limits the patient's limbs or torso, providing excellent lateral support and protection.

[0014] As a preferred or optional embodiment, the back of the first pad has a first fixing member, the back of the second pad has a second fixing member, the back of the third pad has a third fixing member, and the back of the fourth pad has a fourth fixing member. In the unfolded state, the first and fourth fixing members are symmetrically arranged with respect to the center line of the pad's length direction, as are the second and third fixing members. When the pad is deformed into the desired shape, these fixing members can firmly lock the relative positions of each pad, preventing accidental loosening or rebound due to patient movement during use, and ensuring the long-term stability of the folded shape.

[0015] As a preferred or optional solution, the first, second, third, and fourth fasteners are all Velcro. Utilizing the characteristics of Velcro—simple and quick operation, reusability, and moderate adhesive strength—the actions of fixing and releasing the fastener become extremely convenient, improving the efficiency of nursing procedures.

[0016] As a preferred or optional embodiment, the first, second, third, and fourth pads each include an outer casing and an inner liner filled within the outer casing. The outer casing is made of flexible fabric, and the inner liner is made of elastomer. The flexible fabric outer casing provides a skin-friendly, breathable, and easy-to-clean contact surface, while the elastomer inner liner provides the necessary softness, fit, and support, maximizing patient comfort while ensuring the structure can be bent.

[0017] As a preferred or optional solution, the first hinge, the second hinge, and the third hinge are all made of flexible fabric material. Flexible fabric hinges not only allow rotation between the pads but also ensure a smooth and flexible hinge joint without any hard protrusions, improving safety and overall comfort during use.

[0018] In summary, compared with the prior art, this utility model has the following beneficial effects: (1) The nursing pad of this utility model breaks through the limitation of the fixed shape of traditional nursing pads by connecting four pad blocks and three hinge parts. Users can easily bend the hinge parts, so that the same nursing pad can be flexibly switched between unfolded and multiple folded forms, realize dynamic adaptation to different body positions, significantly improve nursing efficiency and convenience, and achieve the effect of one pad for multiple uses.

[0019] (2) The wedge-shaped pad of the nursing pad works in conjunction with the hinge at a specific location to ensure smooth shape transformation and stable results. The overall symmetrical design eliminates the need to distinguish the direction of the product, reducing the complexity of use. The wedge-shaped and convex shapes formed after folding can be used for padding and surrounding protection respectively. By setting the fixing parts, the shape can be quickly locked to prevent accidental loosening and meet diverse and stable clinical support needs.

[0020] (3) The nursing pad uses a flexible fabric hinge and pad outer layer, combined with an elastic inner liner. While ensuring that the structure can be bent, it eliminates the pressure of hard parts and provides a skin-friendly, breathable and highly resilient contact surface, which comprehensively improves the safety and comfort of use.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] It should be noted that similar symbols and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," etc., should be interpreted broadly. For example, "connection" can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] A specific embodiment of this utility model provides a multi-form variable orthopedic nursing pad, which is suitable for positional support and pressure management for orthopedic patients during bed rest, and can meet the comfort support needs of various positions such as supine, lateral, and limb-elevated.

[0030] Combination Figures 1 to 4 As shown, the nursing pad includes a first pad 1, a second pad 2, a third pad 3, and a fourth pad 4 arranged sequentially adjacent to each other. The first pad 1 and the second pad 2 are connected by a first hinge 5, the second pad 2 and the third pad 3 are connected by a second hinge 6, and the third pad 3 and the fourth pad 4 are connected by a third hinge 7. Each hinge allows adjacent pads to rotate relative to each other around their hinge axis. By selectively bending different hinges, the nursing pad can be switched between a fully unfolded shape and at least two three-dimensional folded shapes suitable for different body positions, thus overcoming the shortcomings of traditional nursing pads that have fixed shapes and limited functions.

[0031] Combination Figure 1 and Figure 2 As shown in this embodiment, the cross-sections of the first pad 1, the second pad 2, the third pad 3, and the fourth pad 4 are all designed as wedge-shaped structures. In the unfolded state, each pad is arranged symmetrically along the center line of the length direction of the nursing pad, that is, the first pad 1 and the fourth pad 4 are symmetrical, and the second pad 2 and the third pad 3 are symmetrical, so that the product does not need to distinguish between the head and tail or left and right, which improves the convenience and versatility of use.

[0032] Combination Figure 1As shown, in the unfolded state, the backs of the four pads are flush and coplanar, ensuring a stable fit with the bed surface; the fronts of the four pads form a V-shaped slope, suitable for foot, ankle, or elbow support. The second hinge 6 is located on the front side of the pad (i.e., the wedge-shaped slope side), while the first hinge 5 and the third hinge 7 are located on the back side of the pad. This alternating hinge layout provides natural guidance for subsequent folding in a specific direction.

[0033] Combination Figure 2 As shown, each pad has a component on its back for fixing its shape. Specifically, the back of the first pad 1 has a first fixing member 8, the back of the second pad 2 has a second fixing member 9, the back of the third pad 3 has a third fixing member 10, and the back of the fourth pad 4 has a fourth fixing member 11. In this embodiment, there are two of each of the first fixing member 8, the second fixing member 9, the third fixing member 10, and the fourth fixing member 11. The first fixing member 8 and the fourth fixing member 11 are rectangular, while the second fixing member 9 and the third fixing member 10 are circular. In the unfolded state, the first fixing member 8 and the fourth fixing member 11 are symmetrically arranged, and the second fixing member 9 and the third fixing member 10 are symmetrically arranged. Each fixing member is preferably a hook or loop fastener, which utilizes its easy operation and repeated adhesion characteristics to quickly lock the shape after folding.

[0034] In this embodiment, to achieve comfortable support and convenient deformation, the first pad 1, the second pad 2, the third pad 3, and the fourth pad 4 all adopt a composite structure, including an outer cover sewn from flexible fabric (such as cotton, polyester, medical spandex fabric, etc.) and an elastic inner liner (such as memory foam, high-density sponge, polyurethane, etc.) filled inside the outer cover. The first hinge portion 5, the second hinge portion 6, and the third hinge portion 7 are also made of flexible fabric, and each hinge portion is integrally formed or sewn to the outer cover of the adjacent pad. This fully flexible connection method ensures that the hinge points are flat and soft, without any hard protrusions, improving the sense of security and overall comfort.

[0035] Combination Figure 3 and Figure 4 As shown, the nursing pad has multiple folding configurations. The process of transforming from the unfolded state to the first folded state is as follows: Using the second hinge 6 as an axis, the second pad 2 and the third pad 3 are brought together until their backs are pressed together, while the backs of the first pad 1 and the fourth pad 4 are also pressed together; subsequently, the symmetrically arranged first and fourth fixing members 8 and 11, and second and third fixing members 9 and 10 are glued together to lock the overall shape. At this point, the nursing pad is in the following state: Figure 3 As shown, the whole structure forms a stable wedge-shaped structure with a triangular cross-section, which can be used to maintain the abduction angle of the patient's lower limbs.

[0036] The process of transitioning from the unfolded configuration to the second folded configuration is as follows: with the second hinge portion 6 as the axis, bring the second cushion block 2 and the third cushion block 3 close to each other until their back surfaces are attached to each other; with the first hinge portion 5 as the axis, attach the front surface of the first cushion block 1 to the front surface of the second cushion block 2; with the third hinge portion 7 as the axis, attach the front surface of the fourth cushion block 4 to the front surface of the third cushion block 3, and make the second fixing member 9 and the third fixing member 10 adhere to each other to fix this configuration. At this point, the state of the nursing cushion is as Figure 4 shown, the whole forms a three-dimensional structure with a cross section in the shape of a "convex", the middle protrusion of which can be used for limiting, and the recessed parts on both sides can be used to elevate the limb.

[0037] In summary, the multi-form variable orthopedic nursing cushion provided by this embodiment realizes fast and stable conversion among multiple forms such as the unfolded V-shaped cushion, the wedge-shaped cushion, and the convex-shaped cushion through the innovative combination of wedge-shaped cushion blocks and flexible hinge portions at specific positions. Its symmetrical design simplifies operation, the combination of flexible fabric and elastic inner container ensures comfort, and the hook and loop fastener fixing members ensure the long-term stability of the form, so that a single product meets the diverse clinical posture support requirements, and significantly improves nursing efficiency and patient comfort.

[0038] Although the present utility model is disclosed as above, the protection scope of the present utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model, and these changes and modifications shall all fall within the protection scope of the present utility model.
