Description

Technical Field

[0001] This utility model relates to the field of pillow technology, and in particular to a multifunctional cushion pillow. Background Technology

[0002] In clinical medical care, proper positioning is crucial for the success and safety of establishing an advanced airway or performing neck-related procedures. For example, when performing endotracheal intubation or inserting an internal jugular vein catheter, the patient is usually required to lie supine with effective neck support and the head slightly tilted back. This opens the upper airway, fully exposes the neck area, and provides a clear view and facilitates the procedure. Furthermore, in postoperative or prolonged bed rest care, the angle of the patient's head tilt often needs to be flexibly and stably adjusted to prevent pressure sores, avoid wound compression, or maintain specific treatment positions.

[0003] However, commonly used clinical pillows or fixed pillows are insufficient to meet these complex needs. Their limitations are mainly reflected in the following aspects: First, their functions are fixed and lack modular design. When procedures such as endotracheal intubation are required, the neck support cannot be quickly removed and placed under the patient's shoulders to create a standard reclining position. Second, they lack active adjustment capabilities. They cannot precisely control the left and right tilt angle of the patient's head through inflation and deflation. For example, when a patient has a wound on the left side of their head that requires avoiding pressure, caregivers cannot easily turn the head stably to the right; they can only rely on manual intervention or the use of towels or other items for unstable temporary fixation. This not only increases the workload but also makes it difficult to ensure accurate and sustained positioning, posing certain medical risks.

[0004] Therefore, existing technologies need to be improved and developed. Summary of the Invention

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment of this utility model, a multifunctional pillow is disclosed, including a neck pillow 100, a head pillow 110, and an air control module. The neck pillow 100 includes a neck pillowcase and at least two vertically stacked neck adjustment airbags disposed within the neck pillowcase. The head pillow 110 includes a head pillowcase 111 and an inner pad disposed within the head pillowcase 111. The inner pad includes a base layer 112 and an adjustment layer disposed on the base layer 112. The adjustment layer includes at least two horizontally arranged head tilting airbags 113. The head pillowcase 111 is detachably connected to the neck pillowcase. The air control module includes an air pump and an air tube assembly. The air pump is disposed on the neck pillow 100 or the head pillow 110. One end of the air tube assembly is connected to the air pump, and the other end is connected to all the neck adjustment airbags and the head tilting airbags 113, respectively, for adjusting the air volume of the neck adjustment airbags and independently adjusting the air volume of each head tilting airbag 113.

[0020] In the specific implementation process, when the height of the neck pillow 100 needs to be adjusted, the air control module is activated. An air pump inflates the neck adjustment airbags through the air tube assembly. By selecting to inflate one, several, or all of the neck adjustment airbags and controlling their respective inflation amounts, the overall thickness and support stiffness of the neck pillow 100 can be changed, thereby achieving stepless and precise adjustment of the support height. The deflation process is achieved by controlling the exhaust valve through the air control module; the height decreases after the airbag is depressurized. When it is necessary to adjust the left or right tilt angle of the head, the air control module independently controls the inflation amount of the head tilt airbag 113. For example, to tilt the head to the left, the inflation amount of the right head tilt airbag 113 is increased, while the inflation amount of the left head tilt airbag 113 is decreased or maintained. The bulge of the right airbag smoothly supports the head to the left, and vice versa. Through independent and precise control of the inflation amounts of the left and right airbags, flexible and stable adjustment of the head tilt angle is achieved. The headrest cover 111 and the neck pillow cover are connected by a detachable connector (such as a zipper, button, or Velcro). When procedures requiring shoulder elevation, such as endotracheal intubation, are needed, the connector can be detached, and the neck pillow 100 can be removed separately from the headrest cover 110. The neck pillow 100 can then be placed horizontally under the patient's shoulders and back, and inflated to a suitable height using the air control module to establish a standard medical procedure position. After use, the air is deflated, and the neck pillow 100 is reattached to the headrest cover 110 via the connector, restoring it to its integrated pillow function.

[0021] For example, please refer to Figure 2 The adjustment layer also includes a left limiting pad 114 and a right limiting pad 115 arranged opposite to each other; two head tilting airbags 113 are arranged side by side in the horizontal direction between the left limiting pad 114 and the right limiting pad 115; the left limiting pad 114 and the right limiting pad 115 are used to limit the expansion and deformation of the head tilting airbags 113 to their respective outwards when the airbags are inflated.

[0022] In this embodiment, the left limiting pad 114 and the right limiting pad 115 can be made of rigid or semi-rigid materials, such as rigid plastic, high-density rigid foam, or composite materials. Their key characteristic is that they provide sufficient structural strength to resist the lateral pressure generated by the airbag inflation, thereby achieving effective mechanical limiting. The limiting pads may have a soft cushioning layer on the side facing the airbag to reduce friction and noise; their top surface may also be covered with a soft cushioning layer to improve user comfort.

[0023] During the inflation and limiting process, when the air control module inflates the head tilting airbag 113 (e.g., the first head airbag 1131 on the left), the internal pressure of the airbag increases, causing it to expand outwards. At this time, the left limiting pad 114 located on its outer side provides an immovable boundary condition for the airbag through its rigid structure, physically preventing the airbag from expanding and deforming outwards. According to Pascal's principle and fluid dynamics, the restricted gas pressure will be mainly converted into a thrust perpendicular to the restricted direction, thereby forcing the airbag's expansion force to be concentrated and released inwards (i.e., towards the head support surface), efficiently converting it into a supporting force to lift the head. This process ensures that the deformation of the airbag is precisely guided, achieving precise and stable control of the head tilt angle.

[0024] For example, the adjustment layer further includes a spacer 116 located between the left limiting pad 114 and the right limiting pad 115; the two head tilting airbags 113 are a first head airbag 1131 and a second head airbag 1132, respectively, the first head airbag 1131 being disposed between the left limiting pad 114 and the spacer 116, and the second head airbag 1132 being disposed between the right limiting pad 115 and the spacer 116; the support surface height of the spacer 116 is equal to the support surface height of the first head airbag 1131 and the second head airbag 1132 at the minimum inflation level, such that when the head tilting airbag 113 is at its minimum inflation level, the spacer 116, the first head airbag 1131, and the second head airbag 1132 together form a continuous plane for supporting the head.

[0025] The diaphragm 116 in this embodiment can be made of rigid or semi-rigid materials, such as rigid plastic, high-density rigid foam or composite materials. Its key feature is that it can provide sufficient structural strength to resist the lateral pressure generated by the inflation of the airbag. The diaphragm 116 may be covered with a soft cushioning layer on the side facing the airbag to reduce friction and noise; its top surface may also be covered with a soft cushioning layer to improve user comfort.

[0026] The width of the diaphragm 116 during implementation should be less than the average width of the human head 130. This ensures that, regardless of head position or airbag adjustment, the central area of ​​the user's head is always covered by the diaphragm 116 and at least one head-tilting airbag 113 during use. This ensures that during inflation, the airbags support and lift the head from directly below, rather than pushing it horizontally from the side. During support surface formation, the support surface height of the diaphragm 116 is configured to be equal to the support surface of the head-tilting airbag 113 at its minimum inflation level. When the airbag is at its minimum inflation level, the diaphragm 116 and the two airbags together form a seamless, continuous support plane, providing stable basic support. When adjusting the angle, for example, inflating the first head airbag 1131, the airbag, confined within the cavity formed by the limiting pad and the diaphragm 116 by the lateral boundaries, has its expansion force converted into a vertically upward lifting force; this effectively avoids undue lateral shear force on the neck, making the adjustment process more natural, comfortable, and safe.

[0027] For example, the headrest portion 110 also includes a padded layer, and the top of the headrest cover 111 has an open receiving pocket, the padded layer being detachably disposed within the receiving pocket.

[0028] The cushioning layer can be made of skin-friendly materials such as memory foam, latex, or high-elasticity breathable sponge. Its slow rebound characteristics and soft touch, which conform to the 130° contour of the human head, directly improve the immediate comfort of use. Its detachable structure makes it easy for users to clean and replace the contact layer separately. At the same time, it effectively protects the airbag components below from wear and tear.

[0029] For example, the air control module further includes a timer electrically connected to the air pump; the air control module is configured to periodically control the air pump based on a timing signal generated by the timer to exchange the inflation states of the two head tilt airbags 113.

[0030] The timer starts, and the pneumatic control module controls the air pump to inflate one of the head tilting airbags 113 (e.g., the first head airbag 1131) into a supported state, while the other airbag (the second head airbag 1132) is in a deflated or low-support state. When the timer reaches the preset time period (e.g., 120 minutes) and generates a timing signal, the pneumatic control module controls the air pump to inflate the currently deflated second head airbag 1132, while simultaneously deflating the currently inflated first head airbag 1131. This continues until the inflation states of the two head tilting airbags 113 are completely switched, allowing the previously elevated side of the head to relax and the previously lower side of the head to be smoothly lifted, thus achieving automatic switching of the head tilt direction. This automatically changes the pressure side of the head for long-term bedridden patients, significantly reducing the risk of pressure sores on bony prominences such as the occiput and auricle due to continuous pressure; it also helps relieve static fatigue of the neck muscles, improving the comfort of rest and rehabilitation.

[0031] It should be noted that the timing and pneumatic control technology used in the pneumatic control module is a mature existing technology in this field, and its specific circuit and pneumatic path implementation principle will not be described in detail here.

[0032] For example, the pneumatic control module further includes a soft shell, and the air pump is disposed inside the soft shell; the soft shell is provided with a first connecting structure, and the head pillow 111 and / or the neck pillow is provided with a second connecting structure that cooperates with the first connecting structure; the soft shell is detachably connected to the head pillow 111 or the neck pillow through the cooperation of the first connecting structure and the second connecting structure.

[0033] For example, the first connection structure and the second connection structure are one of a fastener assembly, a Velcro assembly or a zipper assembly that cooperate with each other.

[0034] The soft shell has a rigid slot or bracket that matches the shape of the air pump. The air pump is inserted into and locked in the slot or bracket by interference fit or elastic snap. The air outlet of the air pump extends out of the soft shell. The air tube assembly includes a main air tube and multiple branch air tubes. One end of the main air tube is sealed to the air outlet of the air pump through a quick-connect fitting or threaded interface; the other end of the main air tube extends and is distributed to each branch air tube through a tee or multi-way fitting. The end of each branch air tube is inserted into and fixed to the air inlet of the corresponding air bag through another quick-connect fitting or directly, thereby realizing centralized air supply and control of all neck adjustment air bags and head tilt air bags 113.

[0035] In the specific implementation process, to ensure the stability of the airway and prevent tangling, the air tube assembly can be fixed by one or a combination of the following methods: First, multiple plastic clips are sewn or adhered to the inner walls of the headrest cover 111 and the neck pillow cover, and the air tube is embedded in the clips for fixation. Second, small Velcro straps are used to bind the air tube bundle, and the straps are fixed to the inner wall of the pillow cover using adhesive backing or sewing. Alternatively, grooves or channels for embedding the air tube are pre-set on the base layer 112 or adjustment layer of the inner pad, and the air tube is embedded therein.

[0036] For example, a sound-insulating layer is also provided inside the soft shell, which wraps around the outside of the air pump. The sound-insulating layer inside the soft shell can be made of sound-absorbing cotton, foam, or polymer damping material, and is specifically configured to tightly wrap around the outside of the air pump housing, forming a complete acoustic isolation barrier. This sound-insulating layer can be directly fitted onto the air pump through a prefabricated wrapping structure, or it can be achieved by attaching sound-insulating material to the inner wall of the soft shell, thereby surrounding the air pump from all sides and bottom after installation.

[0037] For example, the head pillowcase 111 and the neck pillowcase are connected by a zipper; the zipper includes a first chain strap and a pull tab disposed at the connecting edge of the head pillowcase 111, and a second chain strap disposed at the connecting edge of the neck pillowcase and engaging with the first chain strap.

[0038] In summary, the multifunctional pillow of this embodiment includes a neck pillow 100, a head pillow 110, and an air control module. The neck pillow 100 contains at least two stacked neck adjustment airbags. The support height of the neck pillow 100 can be changed by controlling the number of inflated neck adjustment airbags and the inflation volume of each airbag. The head pillow 110 is detachably connected to the neck pillow 100 and contains at least two side-by-side head tilting airbags 113. The head tilt angle can be controlled by independently adjusting the inflation volume of the left and right airbags. This invention, through its detachable structure and multi-airbag design, achieves flexible and precise adjustment of the neck support height and head tilt angle. The neck pillow 100 can be removed separately for use to elevate other body parts such as the shoulders and back, offering diverse functions and wide applicability, effectively improving comfort and convenience.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0040] It should be noted that this utility model uses a multifunctional pillow as an example to introduce the specific structure and working principle of the utility model, but the application of this embodiment is not limited to multifunctional pillows, and can also be applied to the production and use of other similar workpieces.
