A medical sleeping pillow with self-adjustable patient usage mode and its method

Abstract

This invention discloses a self-adjustable medical pillow and its method for use, belonging to the technical field of nursing and convalescent equipment. To address the problem of fixed adjustment methods for the pillow, requiring assistance from others or the patient to stand up for adjustment, the first and second motors, when activated, can adjust the distance or angle between the two pillow bodies. This coordinates with the controller in the control box, allowing the pillow to self-adjust based on the patient's actions. The controller assesses the overall pressure and force distribution during use, providing corresponding feedback based on the patient's movements. This allows the patient to adjust the pillow using only slight head pressure without needing to stand up or require assistance. Furthermore, the invention provides a compliance reminder if the patient does not use the pillow for the required duration.

Description

Technical Field

[0001] This invention relates to the field of nursing and convalescent equipment technology, and in particular to a medical prone pillow and method that can adjust the patient's usage mode. Background Technology

[0002] A prone pillow is a cushion designed for comfortable prone lying, especially for patients who need to lie down for extended periods. Prolonged supine lying can easily cause muscle soreness in the back and buttocks, as well as acne scars. A certain amount of prone lying is necessary, particularly for patients who have undergone vitrectomy (vitrectomy) surgery. Vitrectomy is a surgical procedure performed under anesthesia, using a vitrectomy instrument to remove the vitreous humor, photocoagulating to seal the retinal tear, and filling the vitreous cavity with inert gas or silicone oil to reposition the retina. Because silicone oil is lighter than water, when injected into the vitreous cavity, it floats backward and presses against the retina to help it reposition. To ensure the silicone oil better supports the retina, patients must adopt a prone position after vitrectomy and silicone oil filling to improve postoperative outcomes and avoid complications.

[0003] Existing face pillows still have the following problems in actual use:

[0004] Before using a prone pillow, most patients will adjust its position or height in advance. However, during use, patients may feel discomfort or numbness, which may require adjustment of the pillow. At this time, other people need to help the patient adjust it, or the patient may have to get up and adjust it before continuing to lie down and use it, which is very inconvenient. Summary of the Invention

An L-shaped plate is rotatably provided on the rotating end, and the side of the L-shaped plate away from the chassis assembly is connected to the inside of the adjusting box.

[0009] Furthermore, the regulating box is equipped with a bidirectional lead screw, the two ends of which are rotatably connected to the inside of the regulating box. A set of threads with opposite helical directions are symmetrically arranged on the bidirectional lead screw. A second motor is installed inside the regulating box, and the output shaft of the second motor is fixedly connected to one end of the bidirectional lead screw. At least two threaded sleeves are provided on the side of the two L-shaped plates near the regulating box. A transverse groove is opened on the side of the regulating box near the L-shaped plate. The threaded sleeves pass through the transverse groove and extend into the inside of the regulating box. The threaded sleeves on the two L-shaped plates are respectively threadedly connected to the two sets of threads with opposite helical directions on the bidirectional lead screw.

[0010] Furthermore, both sides of the card holder are provided with sliding grooves, and one side of the sliding groove is provided with no less than three card slots connected to the sliding groove. A limiting sleeve is provided on the side of the receiving pad near the card holder, and a sliding rod is rotatably provided inside the limiting sleeve. The sliding rod can slide and move inside the sliding groove, and the sliding rod is slidably engaged inside the card slot.

[0011] Furthermore, the controller includes:

[0012] Interactive control unit, used for:

[0013] It is electrically connected to the control button and receives the control signal sent by the control button. It controls the pressure sensing unit, the mode analysis unit and the intelligent control unit through the control signal and sets the usage time setting value.

[0014] Pressure sensing unit, used for:

[0015] The pressure sensors in different locations and areas are numbered and the sensing signals of each pressure sensor are collected. The pressure values ​​are read and filled into the corresponding pressure areas according to the number markings.

[0016] Pattern analysis unit, used for:

[0017] Set a baseline pressure fluctuation range, and adjust the pillow usage mode based on the pressure values ​​within the pressure range.

[0018] Intelligent control unit, used for:

[0019] The adjustment results based on the usage pattern of the pillow drive the pillow to self-adjust.

[0020] Furthermore, the pressure sensing unit includes:

[0021] The pressure acquisition module is used for:

[0022] The system assigns serial numbers to pressure sensors located in different positions and areas, interacts with the pressure sensors and receives their sensing signals, and marks the sensing signals based on the required markings of the pressure sensors that acquire the sensing signals.

[0023] The pressure processing module is used for:

[0024] Read the pressure values ​​of the induction signals under different serial number markings;

[0025] The pressure positioning module is used for:

[0026] Create pressure zones, which are divided into left and right pressure zones based on the position of the pressure sensor on the pillow body. The pressure values ​​of the sensing signals under different serial numbers are filled into the corresponding pressure zones according to the serial number.

[0027] Furthermore, the pattern analysis unit includes:

[0028] The baseline setting module is used for:

[0029] The raw pressure values ​​collected in the first ten seconds when the pressure sensor is activated after sensing pressure are collected. The raw pressure values ​​are averaged and a reference pressure fluctuation range is generated based on the result of the average value calculation.

[0030] The pressure comparison module is used for:

[0031] The pressure values ​​collected by the pressure sensing unit within each pressure zone are retrieved in real time, and the pressure values ​​are compared with the reference pressure fluctuation range. Pressure zones with pressure values ​​exceeding the highest value of the reference pressure fluctuation range are identified as pressure application zones, and pressure zones with pressure values ​​below the lowest value of the reference pressure fluctuation range are identified as no pressure application zones.

[0032] The pattern determination module is used for:

[0033] Based on whether the left and right pressure areas are determined to be areas of force application, different pillow usage modes are activated.

[0034] in,

[0035] When the left or right pressure zone is identified as the area where force is applied, the external adjustment mode of the bolster is activated.

[0036] When both the left and right pressure zones are identified as force application zones, the bolster angle adjustment mode is activated.

[0037] When the left or right pressure zone is determined to be an area where no force is applied, the bolster adjustment mode is activated.

[0038] When both the left and right pressure areas are determined to be areas where no force is applied and the determination time is less than or equal to three seconds, the bolster angle adjustment mode is activated.

[0039] When both the left and right pressure areas are determined to be areas where no force is applied and the determination time is longer than three seconds, the compliance reminder mode is activated.

[0040] Furthermore, when the intelligent control unit drives the pillow to perform self-adjustment, it adjusts each usage mode according to the following driving method:

[0041] When the external adjustment mode of the bolster is activated, the drive adjustment box causes the two chassis assemblies to move in opposite directions;

[0042] When the bolster adjustment mode is activated, the drive adjustment box moves the two chassis groups toward each other.

[0043] When the bolster angle adjustment mode is activated, the drive unit lifts the adjustment plate upwards;

[0044] When the bolster angle adjustment mode is activated, the drive unit lowers the adjustment plate.

[0045] When the adherence reminder mode is activated, an alarm is triggered to remind the patient of insufficient adherence.

[0046] Another technical problem to be solved by the present invention is to provide a method for a medical sleeping pillow with a self-adjustable patient usage mode, comprising the following steps:

[0047] Step 1: Place the entire prone pillow on the platform, adjust the angle between the adjustment plate and the chassis assembly to a suitable position using the chassis assembly, adjust the angle of the support pad to a suitable position using the snap-fit ​​bracket, and the medical staff input the set value of the usage time required for the patient to use the prone pillow this time through the control box;

[0048] Step 2: When the patient uses the prone pillow, the pressure sensor sends a sensing signal after receiving pressure. The mode analysis unit judges the use mode of the prone pillow based on the pressure value within the pressure area according to the reference pressure fluctuation range and drives the intelligent control unit to perform self-adjustment.

[0049] Step 3: When the patient feels that the gap between the pillow bodies is too small, press the face down onto the pillow body on either side. The mode analysis unit determines that it is the external adjustment mode of the pillow and drives the adjustment box to move the two housings in the opposite direction to widen the gap between the pillow bodies.

[0050] Step 4: When the patient feels that the gap between the pillow bodies is too large, he or she lifts his or her face from either side of the pillow body. The pattern analysis unit determines that it is the pillow adjustment mode and drives the adjustment box to move the two housings towards each other to reduce the gap between the pillow bodies.

[0051] Step 5: When the patient feels that the angle of the prone pillow is too low, lift the face off the prone pillow and put it down within three seconds. The mode analysis unit determines that it is the prone pillow angle adjustment mode and drives the chassis to lift the adjustment plate upward to raise the angle of the prone pillow.

[0052] Step Six: When the patient feels that the angle of the prone pillow is too high, he presses his face down onto the prone pillow. The mode analysis unit determines that it is the prone pillow angle adjustment mode and drives the chassis assembly to lower the adjustment plate to reduce the angle of the prone pillow.

[0053] Step 7: If the patient gets up for more than three seconds without using the set time for this use of the prone pillow, the mode analysis unit determines it to be a compliance reminder mode, activates the alarm, and reminds the patient of insufficient compliance.

[0054] Compared with the prior art, the beneficial effects of the present invention are:

[0055] 1. The first motor of the present invention drives the one-way lead screw to rotate. By controlling the forward and reverse rotation of the one-way lead screw, the threaded block is driven to move along the direction of the one-way lead screw. In turn, the connecting rod drives the adjusting plate to move around the hinge as the center, thereby adjusting the angle of the prone pillow body. This allows it to work in conjunction with the controller in the control box to automatically adjust the angle of the prone pillow according to the patient's operation, improving the convenience and flexibility of using the prone pillow.

[0056] 2. The second motor of the present invention drives the bidirectional lead screw to rotate. By controlling the forward and reverse rotation of the bidirectional lead screw, the threaded sleeve moves in opposite directions, thereby using the L-shaped plate to drive the two housing assemblies to move in opposite directions, thereby adjusting the distance between the two bolster bodies. This allows the bolster to coordinate with the controller in the control box and automatically adjust the width of the bolster according to the patient's operation, so that the bolster can be adjusted according to the patient's comfort during use.

[0057] 3. The present invention can classify and process the sensing signals collected by pressure sensors in different positions and areas through the pressure sensing unit, thereby judging the overall pressure force during the use of the prone pillow. The controller can provide corresponding feedback according to the different actions of the patient, so that the patient does not need to get up or be assisted by others when using the prone pillow. Only a slight force from the patient's own head is needed to make the prone pillow adjust itself. At the same time, if the patient does not use the prone pillow for the required period of time, the controller can remind the patient to comply with the doctor's instructions, ensuring that the patient uses it according to the doctor's instructions, thus saving medical staff the need to supervise patients using the prone pillow.

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] To address the technical issue that patients often pre-adjust the position or height of a prone pillow before use, but may experience discomfort or numbness during use, requiring adjustment, which necessitates assistance from another person or the patient adjusting the pillow themselves before continuing to use it, please refer to [link to relevant documentation]. Figure 1-9 The present invention provides the following technical solutions:

[0070] A self-adjustable medical sleeping pillow for patient use includes two sleeping pillow bodies 1 arranged horizontally and symmetrically. Each sleeping pillow body 1 has an adjustment plate 2 below it. Pressure sensors 13 are evenly distributed on the top surface of the adjustment plate 2, located below the sleeping pillow body 1. Each adjustment plate 2 has a housing assembly 3 below it. A face slot 12 is formed in the middle of each sleeping pillow body 1, and a housing slot 15 is formed in the middle of each housing assembly 3. The face slot 12 and the housing slot 15 are positioned to match. A [missing information - likely a device or feature] is provided on the side of the adjustment plate 2 away from the face slot 12. The connecting end 4 is equipped with an elastic strap 6, which is made of elastic stretch fabric. The two elastic straps 6 are connected by Velcro. The bottom of the adjusting plate 2 is equipped with a hinge 7. The two adjusting plates 2 are respectively hinged to the two chassis assemblies 3 at the bottom through the hinge 7. One of the chassis assemblies 3 is equipped with a control box 5 on its side, and a power cord 8 is provided on the control box 5. The two chassis assemblies 3 are equipped with an adjusting box 9 on the side near the hinge 7. A connecting wire 14 is connected between the control box 5 and the adjusting box 9. The side of the adjusting box 9 away from the chassis assemblies 3 is equipped with a snap-fit ​​bracket 10, and a receiving pad 11 is snapped on the snap-fit ​​bracket 10.

[0071] Specifically, the entire prone pillow is placed on the platform. The angle between the adjustment plate 2 and the chassis assembly 3 is adjusted to a suitable position through the chassis assembly 3. The angle of the support pad 11 is adjusted to a suitable position through the snap bracket 10. Medical staff input the set value of the usage time required for the patient to use the prone pillow through the control box 5. When the patient uses the prone pillow, the pressure sensor 13 sends a sensing signal after receiving pressure. The control box 5 judges the use mode of the prone pillow based on the pressure value within the pressure area according to the reference pressure fluctuation range and drives the intelligent control unit to perform self-adjustment.

[0072] A longitudinal groove 16 is formed on the top surface of the chassis assembly 3. A one-way lead screw 17 is installed inside the longitudinal groove 16. The two ends of the one-way lead screw 17 are rotatably connected to the longitudinal groove 16 through rotary bearings. A threaded block 18 is provided on the one-way lead screw 17. A threaded hole is formed in the middle of the threaded block 18. The threaded block 18 is threadedly connected to the one-way lead screw 17 through the threaded hole. A first motor 20 is installed inside the chassis assembly 3. The output shaft of the first motor 20 is fixed to one end of the one-way lead screw 17. The bottom surface of the adjustment plate 2 is provided with a fixed contact point 21. A connecting rod 19 is provided between the threaded block 18 and the fixed contact point 21. The two ends of the connecting rod 19 are respectively connected to the threaded block 18 and the fixed contact point 21 by a shaft pin. A rotating groove 22 is provided below the side of the chassis assembly 3 near the hinge 7. A rotating end 23 is provided inside the rotating groove 22. An L-shaped plate 24 is rotatably provided on the rotating end 23. The side of the L-shaped plate 24 away from the chassis assembly 3 is connected to the inside of the adjustment box 9.

[0073] Specifically, the first motor 20 starts and drives the one-way lead screw 17 to rotate. By controlling the forward and reverse rotation of the one-way lead screw 17, the threaded block 18 moves along the direction of the one-way lead screw 17. This, in turn, uses the connecting rod 19 to drive the adjusting plate 2 to move around the hinge 7 as the center, thereby adjusting the angle of the prone pillow body 1. This allows it to work in conjunction with the controller in the control box 5 to automatically adjust the angle of the prone pillow according to the patient's operation, improving the convenience and flexibility of using the prone pillow.

[0074] The regulating box 9 is equipped with a bidirectional lead screw 30. The two ends of the bidirectional lead screw 30 are rotatably connected to the inside of the regulating box 9. A set of threads with opposite helical directions are symmetrically arranged on the bidirectional lead screw 30. The regulating box 9 is equipped with a second motor 31. The output shaft of the second motor 31 is fixedly connected to one end of the bidirectional lead screw 30. Each of the two L-shaped plates 24 is provided with no less than two threaded sleeves 32 on the side near the regulating box 9. A transverse groove 29 is opened on the side of the regulating box 9 near the L-shaped plate 24. The threaded sleeves 32 pass through the transverse groove 29 and extend into the inside of the regulating box 9. The threaded sleeves 32 on the two L-shaped plates 24 are respectively threadedly connected to the two sets of threads with opposite helical directions on the bidirectional lead screw 30.

[0075] Specifically, the second motor 31 starts and drives the bidirectional lead screw 30 to rotate. By controlling the forward and reverse rotation of the bidirectional lead screw 30, the threaded sleeve 32 is driven to move in opposite directions. This, in turn, uses the L-shaped plate 24 to drive the two housing assemblies 3 to move in opposite directions, thereby adjusting the distance between the two pillow bodies 1. This allows the system to work in conjunction with the controller in the control box 5 to automatically adjust the width of the pillow according to the patient's operation, so that the width can be adjusted according to the patient's comfort level during use.

[0076] Both sides of the snap-fit ​​bracket 10 are provided with sliding grooves 26. Each side of the sliding groove 26 is provided with at least three slots 25. The slots 25 are connected to the sliding groove 26. The receiving pad 11 is provided with a limiting sleeve 28 on the side near the snap-fit ​​bracket 10. The limiting sleeve 28 is rotatably provided with a sliding rod 27. The sliding rod 27 can slide and move inside the sliding groove 26. The sliding rod 27 is slidably snapped into the slot 25.

[0077] Specifically, by adjusting the position of the sliding rod 27, the height and tilt angle of the support pad 11 can be adjusted, making it convenient for patients to adjust the support pad 11 according to their own physical condition and usage habits for comfort, which is highly flexible.

[0078] The control box 5 includes a display screen, control buttons, a speaker, and a controller. The display screen is located on the top of the control box 5, and the control buttons and speaker are located on the side of the control box 5. The display screen, control buttons, speaker, chassis assembly 3, regulating box 9, and pressure sensor 13 are all electrically connected to the controller.

[0079] The controller includes:

[0080] Interactive control unit, used for:

[0081] It is electrically connected to the control button and receives the control signal sent by the control button. It controls the pressure sensing unit, the mode analysis unit and the intelligent control unit through the control signal and sets the usage time setting value.

[0082] Pressure sensing unit, used for:

[0083] The pressure sensors 13 located in different positions and areas are numbered and the sensing signals of each pressure sensor 13 are collected. The pressure values ​​are read and filled into the corresponding pressure areas according to the number markings.

[0084] Pattern analysis unit, used for:

[0085] Set a baseline pressure fluctuation range, and adjust the pillow usage mode based on the pressure values ​​within the pressure range.

[0086] Intelligent control unit, used for:

[0087] The adjustment results based on the usage pattern of the pillow drive the pillow to self-adjust.

[0088] Specifically, when the patient uses the prone pillow, the pressure sensor 13 sends a sensing signal after receiving pressure. The pressure sensing unit collects, marks, and divides the sensing signal into regions. The mode analysis unit judges the use mode of the prone pillow based on the pressure value within the pressure region according to the reference pressure fluctuation range and drives the intelligent control unit to perform self-adjustment.

[0089] The pressure sensing unit includes:

[0090] The pressure acquisition module is used for:

[0091] The pressure sensors 13 located in different positions and areas are numbered, and the pressure sensors 13 are interacted with and the sensing signals are received. The sensing signals are marked according to the need of the pressure sensors 13 that acquire the sensing signals.

[0092] The pressure processing module is used for:

[0093] Read the pressure values ​​of the induction signals under different serial number markings;

[0094] The pressure positioning module is used for:

[0095] A pressure zone is created, which is divided into a left pressure zone and a right pressure zone based on the position of the pressure sensor 13 on the pillow body 1. The pressure values ​​of the sensing signals under different serial numbers are filled into the corresponding pressure zone according to the serial number.

[0096] Specifically, the pressure sensing unit can divide and process the sensing signals collected by the pressure sensors 13 at different locations and areas, thereby judging the overall pressure situation during the use of the pillow.

[0097] The pattern analysis unit includes:

[0098] The baseline setting module is used for:

[0099] The pressure sensor 13 collects the raw pressure value for the first ten seconds when it senses pressure and starts up. The raw pressure value is averaged and a reference pressure fluctuation range is generated based on the result of the average value calculation.

[0100] The pressure comparison module is used for:

[0101] The pressure values ​​collected by the pressure sensing unit within each pressure zone are retrieved in real time, and the pressure values ​​are compared with the reference pressure fluctuation range. Pressure zones with pressure values ​​exceeding the highest value of the reference pressure fluctuation range are identified as pressure application zones, and pressure zones with pressure values ​​below the lowest value of the reference pressure fluctuation range are identified as no pressure application zones.

[0102] The pattern determination module is used for:

[0103] Based on whether the left and right pressure areas are determined to be areas of force application, different pillow usage modes are activated.

[0104] in,

[0105] When the left or right pressure zone is identified as the area where force is applied, the external adjustment mode of the bolster is activated.

[0106] When both the left and right pressure zones are identified as force application zones, the bolster angle adjustment mode is activated.

[0107] When the left or right pressure zone is determined to be an area where no force is applied, the bolster adjustment mode is activated.

[0108] When both the left and right pressure areas are determined to be areas where no force is applied and the determination time is less than or equal to three seconds, the bolster angle adjustment mode is activated.

[0109] When both the left and right pressure areas are determined to be areas where no force is applied and the determination time is longer than three seconds, the compliance reminder mode is activated.

[0110] When the intelligent control unit drives the pillow to perform self-adjustment, the specific adjustment for each usage mode is as follows:

[0111] When the external adjustment mode of the bolster is activated, the drive adjustment box 9 drives the two chassis groups 3 to move in the opposite direction;

[0112] When the bolster adjustment mode is activated, the drive adjustment box 9 drives the two chassis groups 3 to move towards each other;

[0113] When the bolster angle adjustment mode is activated, the drive unit 3 will lift the adjustment plate 2 upwards;

[0114] When the bolster angle adjustment mode is activated, the drive unit 3 lowers the adjustment plate 2;

[0115] When the adherence reminder mode is activated, an alarm is triggered to remind the patient of insufficient adherence.

[0116] Specifically, when the patient feels the gap between the pillow bodies 1 is too small, they press their face down onto either side of the pillow body 1. The mode analysis unit determines this as an external adjustment mode, driving the adjustment box 9 to move the two housing assemblies 3 in opposite directions, widening the gap between the pillow bodies 1. When the patient feels the gap between the pillow bodies 1 is too large, they lift their face from either side of the pillow body 1. The mode analysis unit determines this as an internal adjustment mode, driving the adjustment box 9 to move the two housing assemblies 3 towards each other, narrowing the gap between the pillow bodies 1. When the patient feels the angle of the pillow body 1 is too low, they lift their face off the pillow body 1 and... If the patient puts down within three seconds, the mode analysis unit determines it to be in the upward adjustment mode of the prone pillow, and drives the housing assembly 3 to raise the adjustment plate 2, increasing the angle of the prone pillow body 1. When the patient feels that the angle of the prone pillow body 1 is too high, and presses their face down towards the prone pillow body 1, the mode analysis unit determines it to be in the downward adjustment mode of the prone pillow, and drives the housing assembly 3 to lower the adjustment plate 2, decreasing the angle of the prone pillow body 1. If the patient gets up before using the required usage time set for this use of the prone pillow (i.e., after more than three seconds), the mode analysis unit determines it to be in the compliance reminder mode, activates the alarm, and reminds the patient of insufficient compliance.

[0117] Specifically, through the pressure sensing unit, pattern analysis unit, and intelligent control unit, the controller can provide corresponding feedback based on the patient's different movements. This allows the patient to adjust the prone pillow without getting up or needing assistance from others. The patient only needs to apply slight force with their head to adjust the pillow as needed. At the same time, the controller can remind the patient to adhere to the prescribed usage time if they do not use the prone pillow for the required duration, ensuring that the patient uses it according to the doctor's instructions and reducing the need for medical staff to supervise patients using the prone pillow.

[0118] To better demonstrate the self-adjustable patient use mode of the medical prone pillow, this embodiment proposes a method for using a self-adjustable patient use mode medical prone pillow, including the following steps:

[0119] Step 1: Place the entire prone pillow on the platform, adjust the angle between the adjustment plate 2 and the chassis 3 to a suitable position using the chassis assembly 3, and adjust the angle of the support pad 11 to a suitable position using the snap-fit ​​bracket 10. Medical staff input the required usage time for the patient using the prone pillow through the control box 5.

[0120] Step 2: When the patient uses the prone pillow, the pressure sensor 13 sends a sensing signal after receiving pressure. The mode analysis unit judges the use mode of the prone pillow based on the pressure value within the pressure area according to the reference pressure fluctuation range and drives the intelligent control unit to perform self-adjustment.

[0121] Step 3: When the patient feels that the gap between the pillow body 1 is too small, he presses his face down to either side of the pillow body 1.
