Abstract

This utility model provides a multifunctional turning pillow, which includes an air bladder with an inclined surface providing support for the human body. The air bladder is connected to an air pump for inflation, and a solenoid valve is connected between the air pump and the air bladder. When the solenoid valve is in the inflation state and the air pump is in the open state, the air pump communicates with the air bladder through the solenoid valve and inflates the air bladder, increasing its size and the inclination angle of the inclined surface. When the solenoid valve is in the deflation state and the air pump is in the closed state, the air bladder communicates with the atmosphere through the solenoid valve, deflating and shrinking, and the inclination angle of the inclined surface decreases. Therefore, this multifunctional turning pillow allows for stepless adjustment of the support angle with a large adjustment range, meeting various needs for adjusting support angles, making it very practical.

Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a multifunctional turning pillow. Background Technology

[0002] For patients who are bedridden for extended periods or whose injured areas cannot withstand heavy pressure, prolonged lying flat can compress blood circulation and easily lead to pressure injuries. To prevent pressure injuries, turning pillows are usually used to help patients who cannot turn over independently or who need to turn over due to spinal fractures, surgery, or other reasons. This also makes it easier for nurses to turn patients over.

[0003] Currently, the cross-section of existing turning pillows is usually a right triangle, a right trapezoid, or an R-shape. When in use, the bottom of the turning pillow is placed on the hospital bed, and the front surface of the turning pillow is inclined so that the patient can lie on their side.

[0004] Chinese patent CN215132049U discloses a turning pillow, which includes a turning pillow body, a pillowcase and a pillow pad placed inside the pillowcase, and a pillow pad including two stacked upper and lower pads with the same structure. The upper pad is a triangular prism structure with an angle of 15° between its upper and lower surfaces. A middle pad may be provided between the upper and lower pads. The middle pad is also a triangular prism structure with an angle of 15° between its upper and lower surfaces. There may be one or two middle pads.

[0005] However, the aforementioned turning pillow achieves angle adjustment by stacking several pads. This adjustment method not only has limited angle options but also has stepped adjustments, which cannot meet the user's needs for various support angles. Utility Model Content

[0006] This application provides a multifunctional turning pillow to solve the technical problem in related technologies where the selection of adjustable angles for turning pillows is limited and cannot meet the user's needs for multiple support angles.

[0007] To solve the above-mentioned technical problems, this application provides a front multi-functional turning pillow, including an air bladder, the air bladder including an inclined surface that provides support for the human body, the air bladder being connected to an air pump for inflation, and an electromagnetic valve being connected between the air pump and the air bladder.

[0008] When the solenoid valve is in the inflation state and the air pump is in the open state, the air pump communicates with the airbag through the solenoid valve and inflates the airbag, the airbag increases in size, and the tilt angle of the inclined surface increases.

[0009] When the solenoid valve is in the deflation state and the air pump is in the off state, the airbag is connected to the atmosphere through the solenoid valve, the airbag deflates and shrinks, and the tilt angle of the inclined plane decreases.

[0010] Furthermore, a cushion layer is laid on the inclined surface, and a first protective structure is provided on the outer surface of the cushion layer.

[0011] Furthermore, the airbag also includes a bottom surface, one side of the inclined surface is connected to one side of the bottom surface; and the other sides of the inclined surface and the corresponding other sides of the bottom surface are connected by expandable and retractable pleated surfaces.

[0012] Furthermore, the turning pillow also includes an anti-slip mat, the bottom surface is fixed on the anti-slip mat, the anti-slip mat is a hard mat, and a second anti-slip structure is provided on the lower surface of the anti-slip mat.

[0013] Furthermore, a storage cavity for placing a cold compress is provided inside and / or below the cushion layer, and the storage cavity has an opening for inserting or removing the cold compress.

[0014] Furthermore, the turning pillow also includes a controller, which is connected to the air pump and the solenoid valve respectively to control the working status of the air pump and the solenoid valve.

[0015] Furthermore, the turning pillow also includes an angle sensor for acquiring the tilt angle of the inclined surface;

[0016] The signal input terminal of the controller is connected to the angle sensor to receive the tilt angle signal acquired by the angle sensor. The signal output terminal of the controller outputs a control signal to control the air pump and the solenoid valve, thereby adjusting the tilt angle of the inclined plane.

[0017] Furthermore, the controller is also equipped with a button and / or key for the user to input a target tilt angle, and the controller can control the solenoid valve and the air pump according to the target tilt angle input by the button and / or key.

[0018] Furthermore, the padding layer is provided with an elastic catheter clamp for holding and fixing the urinary catheter; and / or, the padding layer is provided with a locking seam for holding and fixing the urinary catheter.

[0019] Furthermore, the protrusion on the inner surface of the pleated surface on the back of the airbag is connected to the connection between the bottom surface and the inclined surface by an elastic rope.

[0020] The elastic cord is elastic, allowing the folded surface on the back of the airbag to expand while also pulling on the folded surface on the back of the airbag.

[0021] The multifunctional turning pillow described in this embodiment includes an air bladder, which includes an inclined surface that provides support to the human body. The air bladder is connected to an air pump for inflation, and a solenoid valve connects the air pump and the air bladder. When the solenoid valve is in the inflation state and the air pump is in the open state, the air pump communicates with the air bladder through the solenoid valve and inflates the air bladder, increasing its size and the inclination angle of the inclined surface. When the solenoid valve is in the deflation state and the air pump is in the closed state, the air bladder communicates with the atmosphere through the solenoid valve, deflating and shrinking, and the inclination angle of the inclined surface decreases. Therefore, the multifunctional turning pillow allows for adjustment of the pillow's support angle, with a large adjustment range and stepless adjustment, meeting various needs for support angle adjustment, making it highly practical.

[0030] This application provides a multifunctional turning pillow to solve the technical problem in related technologies where the selection of adjustable angles for turning pillows is limited and cannot meet the user's needs for multiple support angles.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1 As shown, one or more embodiments of this application provide a multifunctional turning pillow. Taking the orientation of the turning pillow in its use state as a reference, the turning pillow includes an airbag 1. The airbag 1 includes a bottom surface 16 and an inclined surface 17. The bottom surface 16 is a plane that can be laid on a flat working surface such as a bed. The inclined surface 17 is also a plane, and one side of the inclined surface 17 intersects and connects with one side of the bottom surface 16. The other three sides of the inclined surface 17 are connected to the corresponding three sides of the bottom surface 16 through expandable and retractable pleated surfaces. Thus, the entire airbag 1 is wedge-shaped. Specifically, both the inclined surface 17 and the bottom surface 16 can be rectangular.

[0033] An air pump 2 is connected to one side of the airbag 11. The air pump 2 inflates the airbag 1, causing it to expand and support the inclined surface 17. The user leans against the inclined surface 17 to support the body. The inclined surface 17 is designed to contact the body during support; the user receives support from the airbag 1 by leaning against it. A soft sponge pad 5 can be laid on the inclined surface 17 to improve comfort. The sponge pad 5 can be fixed to the inclined surface 17 of the airbag 11 by adhesive, or by other methods such as snap-fit ​​connections or detachable connections using Velcro or similar fasteners.

[0034] Furthermore, a first anti-slip structure 9 for increasing friction can be provided on the outer surface of the sponge pad 5. For example, the anti-slip structure can be anti-slip protrusions or anti-slip grooves arranged on the sponge pad 5 to enhance the friction of the human body against the sponge pad 5, prevent slippage, and thus improve the usage effect. Of course, the sponge pad 5 can also be other soft pad layers.

[0035] like Figure 1 , 5 As shown, the air pump 2 is connected to the airbag 1 via a pipe, and a solenoid valve 3 is also connected between the air pump 2 and the airbag 1. By controlling the solenoid valve 3, the airbag 1 can be inflated or deflated. Both the solenoid valve 3 and the air pump 2 are connected to a controller 4, which is used to control the working status of the solenoid valve 3 and the air pump 2.

[0036] For example, by controlling the solenoid valve 3 to be in the inflation state and the air pump 2 to be in the open state, the air pump 2 is connected to the air bladder 1 through the solenoid valve 3. The air pump 2 inflates the air bladder 1, causing it to gradually expand. This increases the tilt angle of the inclined surface 17 relative to the bottom surface 16, thus increasing the support angle of the turning pillow. Conversely, by controlling the solenoid valve 3 to be in the deflation state and the air pump 2 to be in the closed state, the air bladder 1 is connected to the atmosphere through the solenoid valve 3, causing it to deflate and gradually shrink. This decreases the tilt angle of the inclined surface 17 relative to the bottom surface 16, thus decreasing the support angle of the turning pillow. In this way, the support angle of the turning pillow can be adjusted, with a large adjustment range and stepless adjustment, meeting various needs for adjusting the support angle, making it very practical.

[0037] Furthermore, the turning pillow also includes an angle sensor 6 for monitoring the tilt angle of the inclined surface 17 (i.e., the angle between the inclined surface 17 and the bottom surface 16, i.e., the support angle). The angle sensor 6 can be installed on the sponge pad 5 or inside the air bladder 1, and the angle sensor 6 is connected to the controller 4 to send the collected real-time tilt angle information to the controller 4. The controller 4 is provided with a button or key for the user to input the target tilt angle. The controller 4 can control the angle sensor 6, the solenoid valve 3, and the air pump 2 according to the target tilt angle input by the button or key and the real-time tilt angle information sent by the angle sensor 6 until the real-time tilt angle collected by the angle sensor 6 is consistent with the target tilt angle. Then, the solenoid valve 3 and the air pump 2 are closed, thereby adjusting the tilt angle to the target tilt angle to meet the user's needs.

[0038] It should be noted that the specific algorithm and program for adjusting the tilt angle embedded in the controller 4 are existing technologies and are not within the scope of protection of this application, and will not be described in detail here.

[0039] Furthermore, for user convenience, the controller 4 can be equipped with options for different tilt angles for direct selection. When a user selects an option, the controller 4 adjusts the tilt angle according to the aforementioned adjustment method. For example, the controller 4 has three adjustment option buttons: 20 degrees, 30 degrees, and 45 degrees. After the user clicks the button for the corresponding setting, the controller 4 adjusts the tilt angle of the inclined surface 17 to that setting according to the aforementioned method, thereby making the adjustment of the support angle of the turning pillow visible. For example, Figure 1 , 2 This is a structural diagram of the turning pillow when the tilt angle is 30 degrees. Figure 3 This is a schematic diagram of the structure of the turning pillow when tilted at 20 degrees. Figure 6 This is a structural diagram of the turning pillow when the tilt angle is 45 degrees.

[0040] In addition, for ease of user operation, the controller 4 can be designed as a handheld device for remote control. This allows users to adjust the support angle of the turning pillow at any time (even while lying in bed), making it very convenient and easy to use.

[0041] like Figures 1-3 As described in 5 to 7, in order to improve the stability of the airbag 1 when placed on the bed surface, the bottom surface 16 is set on the anti-slip mat 10, and the lower surface of the anti-slip mat 10 is provided with an anti-slip groove 11 or an anti-slip protrusion, etc., as a second anti-slip structure, to improve the friction between the anti-slip mat 10 and the bed surface, and to prevent the pillow from shifting on the bed surface when turning over, thus affecting the use effect.

[0042] Specifically, the bottom surface 16 of the airbag 1 can be bonded and fixed to the anti-slip pad 10. The anti-slip pad 10 can be made of a rigid material and is rectangular in shape. For example, the anti-slip pad 10 can be a rubber pad 10, which can improve the overall support of the turning pillow and also protect the bottom surface 16 of the airbag 1.

[0043] A storage cavity 7 for placing a cold compress 8 can be provided inside or below the sponge pad 5. In this way, when the user leans on the sponge pad 5 of the turning pillow, a cold compress can be applied at the same time. When there is mild inflammation or swelling at the pressure sore site, the cold compress can help reduce local swelling and pain. The cold compress temporarily reduces the inflammatory response and relieves pain by constricting blood vessels, which is especially effective when the pressure sore has not yet ruptured or is in the red and swollen stage.

[0044] For example, in one embodiment of this application, the sponge pad 5 is relatively thick, the sponge pad 5 has the storage cavity 7 inside, and the sponge pad 5 has an opening for the storage cavity 7 so that the cold compress 8 can be inserted or removed through the opening.

[0045] Alternatively, in one embodiment of this application, the sponge pad 5 is thinner, and the gap between the sponge pad 5 and the inclined surface 17 forms the storage cavity 7. Inserting the cold compress 8 into the gap between the sponge pad 5 and the inclined surface 17 can also achieve the effect of cold compress.

[0046] Furthermore, the front side (the side in contact with the human body) of the sponge pad 5 is also provided with an elastic catheter clamp 14 for clamping and fixing the urinary catheter and other tubes.

[0047] Furthermore, the front side (the side in contact with the human body) of the sponge pad 5 is provided with a clamping slot 15 for clamping and fixing the urinary catheter. Specifically, the clamping slot 15 can extend from the sponge pad 5 to the back side of the balloon 1, and even to the anti-slip pad 10. The clamping slot 15 is recessed into the surface of the sponge pad 5, the back side of the balloon 1, and / or the anti-slip pad 10. The user can freely choose the elastic catheter clamp 14 or the clamping slot 15 to clamp the urinary catheter, preventing the urinary catheter from being pressed when the patient turns over.

[0048] The side surface of the airbag 1 is a pleated surface, which includes pleated grooves 12. The expansion and contraction of the pleated surface increases and decreases the area of ​​the side surface of the airbag 1, thereby increasing and decreasing the volume of the airbag 1. Figure 1 , 7 As shown, the protrusion on the inner surface of the pleated surface 18 on the back of the airbag is connected to the connection between the bottom surface 16 and the inclined surface 17 by an elastic rope 13. The elastic rope 13 is elastic, which allows the pleated surface to expand and also has a pulling effect, preventing the pleated surface on the back from expanding too much, which would cause the entire turning pillow to become unstable, thereby improving the overall user experience.

[0049] An exemplary usage process of the multifunctional turning pillow described in this application embodiment is as follows:

[0050] Place the cooling compress 8 into the storage cavity 7 as needed, and place the turning pillow at the target position on the bed surface;

[0051] The tilt angle of the inclined surface 17 can be adjusted by the controller 4 to obtain a comfortable support angle;

[0052] The user lies with their back against the inclined surface 17 of the turning pillow; and can further and at any time adjust the tilt angle of the inclined surface 17 through the controller to make it comfortable to lie down.

[0053] When you need to turn over, use the controller to adjust the support angle of the turning pillow to a position that facilitates turning over. After turning over, adjust the support angle again to a position that facilitates comfortable lying down.
