Description

Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, specifically to a multifunctional combination pillow for postoperative rehabilitation and long-term bedridden patients. Background Technology

[0002] In orthopedics, trauma surgery, and rehabilitation nursing, providing appropriate positional support for patients is a fundamental and crucial nursing measure. This mainly includes: elevating the affected limb when the patient is lying down to reduce swelling and prevent deep vein thrombosis; providing support when the patient is turning on their side to assist in turning over and prevent pressure sores; and providing stable and comfortable support for the lower back and buttocks when the patient changes from a lying to a sitting position (such as eating, reading, or performing upper limb activities in bed).

[0003] To meet these needs, various nursing pads, pillows, and related assistive devices have emerged on the market. Clinical and home settings often require the separate preparation of multiple independent devices such as leg pillows, turning cushions, and backrest pillows. This not only occupies space and increases costs but also places an operational and memory burden on caregivers, especially family members providing home care. In actual nursing practice, the quality of care can easily be affected by incomplete or inconveniently accessible devices. Existing modular nursing pads consist of multiple independent foam modules (such as strip-shaped, L-shaped, and wedge-shaped pads) temporarily assembled using Velcro or similar methods. While these products can provide a certain degree of support, elevation, side blocking, or turning support through combination, their components are scattered, making operation cumbersome. Nurses or family members need to find and assemble the corresponding modules according to different nursing needs, resulting in low efficiency and a high risk of loss. Furthermore, the connections between modules are unstable, lacking overall integrity, and are prone to loosening or shifting after patient movement or prolonged pressure, affecting the effectiveness and safety of nursing care. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional combination pillow to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model provides a multifunctional combination pillow, comprising: The pillow body has a supportive curved surface at the top that conforms to the curve of the human leg, and the front side of the pillow body has a slope that extends forward and downward. The folding wings are connected to the left and right sides of the pillow body via flexible hinges made of pillowcase fabric. The pillowcase fabric surface where the folding wings fit against the pillow body is provided with a first fixing component for detachably fixing the folding wings to the pillow body when they are flat. The top of the folding wings after they are folded upwards is provided with at least one second fixing component. The folding wings on both sides are connected to each other through the second fixing component so that the pillow body and the folding wings form a U-shaped enclosure.

[0006] This invention solves the problem in existing technologies that require multiple independent devices (such as pillows and fixed baffles) to achieve limb elevation, anti-sway function, and assisted turning by quickly switching between two states: a flat position for sitting back support and a U-shaped baffle for elevating the affected limb. Patients and caregivers can flexibly adjust the product's form according to their needs without replacing or finding additional accessories, thus improving the convenience and efficiency of care.

[0007] As a further improvement of this utility model, the multifunctional combination pillow also includes an inflatable limiting structure, the inflatable limiting structure comprising: An inflatable airbag is disposed on the first side facing each other when the folding wing is in the U-shaped enclosure state; An inflation valve is located on a second side away from the first side, and the inflation valve is connected to the airbag through a flexible inflation tube placed inside the folding wing.

[0008] The inflatable bladder in this improved design is located on the first side of the folding wing. After inflation, it expands towards the head, forming a soft contact surface that adapts to the side profile of the affected limb, providing uniform lateral restraint force. It is more comfortable and safer than rigid baffles or straps.

[0009] As a further improvement of this utility model: the multifunctional combination pillow also includes a front pillow body, the two sides of which are fastened to the two sides of the slope portion by detachable connecting straps. In this embodiment, when the product is used as a seated backrest, it provides dedicated, ergonomic neck support, solving the problem of neck stagnation while seated, and improving comfort and support integrity.

[0010] As a further improvement of this utility model: the first fixing component includes a hook side and a rough side of the hook and loop fastener that cooperate with each other. The hook and loop fastener meets the needs of frequent opening and closing, low cost, and convenient operation, achieving an effective combination of strong fixing and convenient operation. The hook and loop fastener makes a loud sound and provides a clear tactile feedback when it is torn open, indicating to the operator that it has been released; when it is to be fastened, it only requires a light press to firmly adhere, and it can be repeatedly opened and closed thousands of times without failing.

[0011] As a further improvement of this utility model: the second fixing component includes a strap or connecting strap and a buckle and a snap fastener that cooperate with it. The strap or connecting strap connects and fixes the two folding wings together, providing a balance between a firm connection and quick release, allowing caregivers or patients to easily and single-handedly switch modes and fix the device.

[0012] As a further improvement of this utility model: the supporting curved surface of the pillow body and the sloping part are integrally formed, and its interior is filled with sponge, forming a continuous curved surface that smoothly transitions from the back side of the pillow body to the front and downward. The integrally formed continuous curved surface avoids gaps, sharp corners or sudden changes in hardness that may occur when splicing parts, making the pressure distribution on the legs more uniform.

[0013] As a further improvement of this utility model: an auxiliary positioning structure is provided between the folding wing and the pillow body. The auxiliary positioning structure includes an elastic protrusion on one side of the folding wing and a recess on one side of the pillow body. The elastic protrusion is a silicone particle or elastic protrusion structure sewn into the inner layer of the side of the folding wing, and the corresponding recess is a hole formed by local compression molding of the sponge on the side of the pillow body. When the two are combined, the protrusion is embedded in the recess, producing a clear positioning feel.

[0014] As a further improvement of this utility model: multiple airbags are arranged equidistantly along the length of the folding wing, and each airbag is a long strip-shaped airbag extending along the width of the folding wing. By arranging multiple long strip-shaped airbags along the length direction, segmented adaptive pressure and support can be achieved on the side of the affected limb. Different leg areas (such as thinner ankles and thicker calves) can be accommodated by the expansion of different airbags, providing a more fitting and uniform circumferential pressure, avoiding the problems of localized pressure points or insufficient support that may occur with a single large airbag.

[0015] As a further improvement of this utility model: multiple inflatable bladders located in the same folding wing are connected sequentially by connecting air tubes, and the inflation valve is connected to one of the inflatable bladders through a flexible inflation tube. During inflation, gas enters the first inflatable bladder from the inflation valve. When its pressure reaches the opening pressure of the connecting air tube, the gas flows into the next inflatable bladder, and so on, until the pressure of all the air bladders is basically balanced.

[0016] As a further improvement of this utility model, the inflation limiting structure also includes a safety relief valve, which is connected to the inflation bladder. This improvement prevents the risk of pressure injury to the affected limb due to overinflation. The safety relief valve automatically opens to release air when the pressure inside the bladder exceeds a preset safety value until the pressure returns to normal, providing passive safety protection for patients who are unconscious, have sensory impairments, or are operating improperly, thus enhancing the product's safety level and medical professionalism.

[0022] Reference Figure 1 and Figure 2 The following are several embodiments of a multifunctional combination pillow according to the present invention.

[0023] An embodiment of this utility model provides a multifunctional combination pillow, such as... Figure 1 and Figure 2 As shown, it includes: The pillow body 100 has a support surface 110 at its top that conforms to the curve of the human leg, and the front side of the pillow body 100 is provided with a slope portion 120 that extends forward and downward. Folding wings 200 are connected to the left and right sides of the pillow body 100 via flexible hinges 210 made of pillowcase fabric. A first fixing component 220 is provided on the pillowcase fabric surface where the folding wings 200 are in contact with the pillow body 100, for detachably fixing the folding wings 200 in the flat state to the pillow body 100. At least one second fixing component 230 is provided at the top of the folding wings 200 after they are folded upwards. The folding wings 200 on both sides are connected to each other through the second fixing components 230 so that the pillow body 100 and the folding wings 200 form a U-shaped enclosure.

[0024] In this embodiment, the curved support surface at the top of the pillow effectively supports the lumbar region when used as a seated backrest, preventing patients from feeling unsupported or fatigued. The flexible hinge section is constructed from the pillowcase fabric itself connecting the pillow body and the folding wings; it is a section of fabric without foam filling, allowing for free bending. The interior of the pillow body and folding wings is preferably filled with high-elasticity polyurethane foam (density 40D-60D), which provides sufficient support and resilience while ensuring easy cutting and shaping into the desired curves and shapes. The exterior is covered by an elastic knitted fabric pillowcase. In operation, this embodiment is in a flat position, with the folding wings flattened and secured to both sides of the pillow body by the first fixing component (such as Velcro). At this time, the pillow body, the ramp, and the front pillow can collectively form a backrest structure suitable for sitting posture, serving as a backrest pillow with a supporting curved surface, and can also be used to assist in turning over. When switching to the U-shaped enclosure, tear off the Velcro, fold the two side wings upwards, and fasten them together using the second fixing component (such as straps and buckles) at the top of the folded wings to form a three-sided enclosure. At this time, the affected limb is placed on the supporting curved surface of the occipital body, with the upright folding wings limiting its position on both sides.

[0025] This embodiment utilizes a pillow and folding wings to enable a single product to quickly switch between two modes: a flat position for sitting back support and a U-shaped support for elevating the affected limb. This solves the problem in existing technologies where multiple independent devices (such as pillows and fixed supports) are required to elevate the affected limb, prevent swaying, and assist with turning over. Patients or caregivers can flexibly adjust the product's form according to their care needs without changing or finding additional accessories, improving the convenience and efficiency of care.

[0026] In an optional embodiment, such as Figure 2 As shown, the multifunctional combination pillow also includes an inflatable limiting structure, which includes: An inflatable airbag 310 is disposed on the first side 240 facing each other when the folding wing 200 is in the U-shaped enclosure state; An inflation valve 320 is located on a second side 250 away from the first side 240. The inflation valve 320 is connected to the airbag 310 through a flexible inflation tube located inside the folding wing 200.

[0027] In this embodiment, the inflatable bladder is placed on the first side of the folding wing (the side facing the pillow body after folding). After inflation, it expands towards the pillow body, forming a soft contact surface that adapts to the side contour of the affected limb, providing uniform lateral restraint force, which is more comfortable and safer than rigid baffles or straps.

[0028] It should be noted that the air inlet of the inflation valve in this embodiment is constructed as a standard socket-type interface, which can be directly connected to the conical nipple connector of a manual squeezing inflation ball. In use, the nipple connector of the manual inflation ball is directly inserted into the socket interface of the inflation valve, and air is supplied to the airbag by repeatedly squeezing the inflation ball. The inflation valve can also be connected to the output pipe of an electric inflation device via an adapter pipe. Users can freely choose the inflation method according to their usage scenario (e.g., convenient electric equipment in hospitals, simple manual operation at home) and needs (e.g., rapid inflation, precise pressure control).

[0029] In an optional embodiment, such as Figure 1 As shown, the multifunctional combination pillow also includes a front pillow body 130, which is fastened to both sides of the slope portion 120 via detachable connecting straps 131. In this embodiment, when used as a seated backrest, it provides dedicated, ergonomic neck support, addressing the pain point of neck suspension while seated, and improving comfort and support integrity. Simultaneously, the front pillow body itself can function as an independent long pillow, which, when detached, can be used separately as a travel neck pillow, nap pillow, or auxiliary pillow to elevate the body. Its combination with the main pillow body provides complementary functions: the main pillow body provides core lumbar / back / leg support, while the front pillow body provides optional neck support. This allows the product to not only meet core care needs such as elevating the affected limb, fixing and preventing swaying, assisting in turning over, and providing lumbar support while seated, but also further cover the needs of seated neck care, expanding the product's functional scope and market applicability.

[0030] In an optional embodiment, such as Figure 2 As shown, the first fastening component 220 includes a hook side and a loop side of Velcro that cooperate with each other. This embodiment uses Velcro as the preferred method for the first fastening component, which meets the needs of frequent opening and closing, low cost, and convenient operation, effectively combining fastening strength with ease of operation. The Velcro makes a loud sound and provides a clear tactile feedback when torn, indicating to the operator that it has been released; when fastened, it only requires a light press to firmly adhere, allowing for thousands of repeated opening and closing without failure.

[0031] In an optional embodiment, such as Figure 2As shown, the second fixing component 230 includes a strap or connecting strap and a buckle and a snap fastener that cooperate with it. The strap or connecting strap, buckle and snap fastener are existing mature connectors that are low in cost and easy to operate. The strap or connecting strap connects and fixes the folding wings on both sides, providing a balance between a firm connection and quick release, allowing caregivers or patients to easily and with one hand switch modes and fix the device.

[0032] In an optional embodiment, such as Figure 1 As shown, the supporting curved surface 110 of the pillow body 100 and the ramp portion 120 are integrally molded structures, with the interior filled with sponge, forming a continuous curved surface that smoothly transitions from the rear side of the pillow body 100 to the front and downward. A continuous curved surface means that there are no obvious folds or steps between the supporting curved surface and the ramp portion, but rather a smooth transition, with a gentle change in curvature in the transition area. The integrally molded continuous curved surface avoids gaps, sharp edges, or abrupt changes in hardness that may occur with split-part assembly, resulting in a more even distribution of pressure on the legs.

[0033] In an optional embodiment, such as Figure 2 As shown, an auxiliary positioning structure 140 is provided between the folding wing 200 and the pillow body 100. The auxiliary positioning structure 140 includes an elastic protrusion on one side of the folding wing 200 and a recess on one side of the pillow body 100. The elastic protrusion is a silicone particle or elastic protruding structure sewn into the inner layer of the side of the folding wing, with a diameter of about 5-10 mm. The corresponding recess is a hole formed by local compression molding of the sponge on the side of the pillow body. When the two are combined, the protrusion is embedded in the recess, producing a clear positioning feel.

[0034] In an optional embodiment, such as Figures 1 to 2 As shown, multiple airbags 310 are arranged equidistantly along the length of the folding wing 200. Each airbag 310 is a long strip-shaped airbag extending along the width of the folding wing 200. Two to four independent long strip-shaped airbags, each 60mm-100mm wide, can be placed within each folding wing, extending along the width of the folding wing. The airbags are made of TPU (thermoplastic polyurethane) film through high-frequency welding, possessing excellent flexibility and airtightness. The parallel arrangement of multiple airbags forms a flexible restraint surface that can flexibly adapt to irregular limb contours.

[0035] In this embodiment, the airbags are configured as multiple elongated strips arranged along the length, enabling segmented adaptive pressure and support on the side of the affected limb. Different leg areas with varying thicknesses (such as thinner ankles and thicker calves) can be accommodated by the expansion of different airbags, providing a more fitted and even circumferential pressure, avoiding the problems of localized pressure points or insufficient support that may occur with a single large airbag.

[0036] In an optional embodiment, such as Figures 1 to 2As shown, multiple inflatable bladders 310 located within the same folding wing 200 are sequentially connected via connecting air tubes. The inflation valve 320 is connected to one of the inflatable bladders via a flexible inflation tube. The connecting air tube is a flexible plastic tube with an inner diameter of 2mm-3mm, concealed within the sponge padding or in pre-fabricated grooves inside the folding wing. During inflation, gas enters the first inflatable bladder through the inflation valve. When its pressure reaches the opening pressure of the connecting air tube, gas flows into the next inflatable bladder, and so on, until the pressure of all the inflatable bladders is essentially balanced.

[0037] In an optional embodiment, the inflation limiting structure further includes a safety relief valve connected to the inflation bladder. The safety relief valve is a miniature spring diaphragm valve, directly integrated into the bladder wall, inflation tubing, or inflation valve. Its opening pressure needs to be precisely calibrated according to clinical safety pressure standards, for example, set at 35 mmHg (approximately 4.7 kPa). Once this value is exceeded, the valve opens, emitting a slight hissing sound as air is released, and the pressure drops. This embodiment prevents the risk of compression injury to the affected limb due to overinflation. The safety relief valve automatically opens to release air when the pressure inside the bladder exceeds a preset safety value until the pressure returns to normal, providing passive safety protection for patients with impaired consciousness, sensory impairment, or improper operation, thus enhancing the product's safety level and medical professionalism.

[0038] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
