Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a turning pillow for long-term bedridden patients with body temperature monitoring and time setting. Background Technology

[0002] In clinical practice, long-term bedridden patients need to be turned regularly (usually every 2 hours) to avoid prolonged pressure on the local skin, which can obstruct blood circulation and lead to pressure ulcers. Sometimes, due to busy work schedules or other reasons, nursing staff may forget to turn the patient, resulting in prolonged pressure on the patient's contact surface with the bed, increasing the risk of pressure ulcers. According to medical data and relevant medical literature, for every 1°C increase in body temperature, the oxygen demand of tissue metabolism increases by 10%. Under sustained pressure, this can cause tissue ischemia. A local temperature ≥37°C is considered the high-risk temperature threshold for pressure ulcers; therefore, elevated body temperature increases the susceptibility to pressure ulcers. Existing turning pillows possess the basic functions of "inflatable, breathable, supporting body position, and assisting turning," but they still have significant drawbacks: 1. Lack of timed reminders: Caregivers need to rely on manual timing or memory reminders to turn patients, but due to busy work or other reasons, they may forget the time to turn the patient, resulting in prolonged pressure on the contact surface between the patient and the bed, increasing the risk of pressure sores; 2. Lack of temperature monitoring: The area where the patient's skin contacts the turning pillow is prone to temperature rise due to poor local ventilation and pressure accumulation. Existing turning pillows cannot sense temperature changes in this area and cannot provide early warning of the dual risks of "high temperature + high pressure"; 3. Insufficient nursing initiative: They only passively provide support and cannot proactively convey key information such as "need to turn" or "local overheating" to caregivers or patients, relying on manual inspections, resulting in low nursing efficiency and limited safety.

[0003] Utility model patent No. 202420868259.7 discloses a turning pillow with a timer reminder function. Its main technical features are: one end of a rotating plate is hinged to a base plate, and the other end of the rotating plate is movably mounted. A lifting device is mounted on the base plate, and the angle of the rotating plate is adjusted by the lifting device. A sliding rod is provided on the movable plate, and a sliding groove is provided on the rotating plate. The movable plate is mounted on the rotating plate via the sliding rod, and the sliding rod is retractable within the sliding groove. A trigger device is located at the bottom of the sliding groove and is electrically connected to a timer alarm device. When the patient leans against the turning pillow, they press the movable plate, causing the sliding rod to press against the trigger device. The trigger device then controls the timer alarm device to start timing. When the preset time is reached, the timer alarm device sounds an alarm to remind medical staff to adjust the patient's position. In this technical solution, the timer is activated by the patient leaning against the turning pillow and pressing the movable plate, causing the sliding rod to press against the trigger device. The trigger device then controls the timer alarm device to start timing, and when the preset time is reached, the timer alarm device sounds an alarm.

[0004] In summary, since existing turning pillows generally have basic functions such as inflation, ventilation, body position support, and assisting turning, but do not have the function of monitoring the patient's body temperature, the present invention provides a turning pillow with body temperature monitoring and time setting for long-term bedridden patients.

This turning pillow uses a time control module to control the time, and the timed reminder function avoids manually missing the turning time, ensuring that the patient is turned every 2 hours (or the preset time), solving the defects of traditional "passive waiting care", and reducing the risk of pressure ulcers by more than 60%. 3. This turning pillow uses a mesh temperature sensing element to monitor the patient's body temperature and controls the body temperature through a temperature control module. It monitors the contact temperature in real time. When the local temperature is ≥37℃ (the high-risk temperature threshold for pressure ulcers), it intervenes in time through sound and light prompts (such as adjusting the position of the pillow or increasing ventilation) to avoid skin damage caused by "high temperature and high pressure". This fills the functional gap of traditional turning pillows that "do not have temperature monitoring". 4. This turning pillow processes various data through a central processing unit (CPU), converts digital signals into video signals through a visual processing module and displays them on a monitor, converts digital signals into audio signals through an audio processing module, and converts electrical signals into light signals through a photoelectric conversion module; 5. When using this turning pillow, there is no need for nursing staff to frequently time and inspect manually. The prompt module actively transmits key information, reducing the workload of nursing staff in postural care by 30%, which is especially suitable for departments or home scenarios where there is a shortage of nursing staff. 6. The control panel of this turning pillow is simple, with only touch function keys for power on / off, time setting, temperature setting, and volume adjustment. Elderly patients or home caregivers can quickly get started, reducing the barrier to use. 7. This turning pillow has demonstrated higher safety and effectiveness in clinical applications. It can effectively remind medical staff to turn patients over in a timely manner, thereby reducing the pain and medical risks for patients during the turning process. 8. This turning pillow has a reasonable structural design, is simple, convenient and practical to operate, reduces the difficulty of the nursing process, can be widely used in clinical practice, and is suitable for most hospitals and families.

The output end of the vision processing module 25 is connected to the input end of the display screen 3 by wires 14. The buzzer 13 is installed on the side plate 9 on the other side of the pillow frame 6. The output end of the volume adjustment knob 12 is connected to the input end of the audio processing module 23 by a wire 14. The output end of the audio processing module 23 is connected to the input end of the buzzer 13 by a wire 14. The two side plates 9 on both sides of the pillow frame 6 are connected to the side baffle 27 by connecting bolts 5 through the bolt holes 24. The back plate 4 is installed on the back of the pillow frame 6 by connecting bolts 5 through the bolt holes 24.

[0019] Side baffles 27 are fixed to both ends of the bottom reclining plate 28 of the inclined reclining plate assembly 7. Through holes 29 are opened on the reclining plate 28. Breathable cotton pads 30 are placed in the space formed by the reclining plate 28 and the two side baffles 27. Mesh temperature measuring elements 21 are placed on top of the breathable cotton pads 30. Fabric layers 31 are placed on top of the mesh temperature measuring elements 21. The periphery of the fabric layers 31 is fixedly connected to the two side baffles 27 and the upper and lower ends of the pillow frame 6, respectively. The wires 14 on the mesh temperature measuring elements 21 pass through the through holes 29 and are connected to the input end of the temperature control module 20.

[0020] The lying board 28 in the turning pillow forms an acute angle of 30 degrees with the horizontal base plate 16. The fabric layer 31 is made of durable and breathable pure cotton fabric, and a waterproof layer is set on the layer where the pure cotton fabric contacts the mesh temperature measuring element 21.

[0021] Before use, connect the charging cable to the charging interface 11 to charge the rechargeable battery 18. When the charging indicator light 10 is solid green, it indicates that the rechargeable battery 18 is fully charged. Under fully charged conditions, the rechargeable battery 18 has a battery life of ≥24 hours. Medical staff can turn on the device using the power on / off touch button on the operation panel 1, and set the turning interval using the time setting touch function key 2. The turning interval is generally 2 hours by default, but can be adjusted within 1-4 hours. The set value is then input into the central processor (CPU), transmitted to the video processing module 25 via the time control module 26, and then transmitted to the display screen 3 via the video processing module 25. The display screen 3 will display the countdown time. The patient's body temperature range is set using the temperature setting touch function key 2. The body temperature range is generally set to 35℃-40℃, with a fluctuation accuracy within ±0.5℃. The set value is then input into the central processor (CPU), transmitted to the display screen 3 via the video processing module 25, and the display screen 3 will display the set temperature value. After the above preparations are completed, the turning pillow can be turned off for standby.

[0022] When in use, the patient can lie flat on the turning pillow. Medical staff can turn it on using the power on / off touch button on the control panel 1. The display screen 3 will show the countdown time and the set temperature value. At the same time, the volume adjustment knob 12 can be used to adjust the volume of the buzzer 13 to a moderate level. When the set countdown time reaches zero, the central processor (CPU) issues a command. After receiving the command, the audio processing module 23 emits a "beep beep" alarm sound (the volume is about 60 decibels) through the buzzer 13. At the same time, the photoelectric conversion module 22 makes the alarm indicator light 8 flash yellow, reminding the nursing staff to assist the patient in turning over. After turning over, the nursing staff presses the "reset" button, the central processor (CPU) restarts the countdown, the time control module 26 and the video processing module 25 start working again, and the display screen 3 will show the new countdown time.

[0023] If the patient's body temperature is ≥37℃ when the turning interval has not been reached, the temperature control module 20 transmits the monitored value to the central processor (CPU). The central processor (CPU) issues a command, and the audio processing module 23, upon receiving the command, emits a "beep" alarm sound (approximately 60 decibels) through the buzzer 13. At the same time, the photoelectric conversion module 22 causes the alarm indicator 8 to flash red, reminding the nursing staff to adjust the pillow position or change the patient's position in time. Once the temperature drops to <37℃, the alarm indicator 8 will automatically stop.

[0024] After the turning pillow has been used for more than 24 hours, when the charging indicator light 10 flashes green, it indicates that the rechargeable battery 18 is low on power. Medical staff can charge the rechargeable battery 18 by connecting the charging cable to the charging interface 11. When the charging indicator light 10 shows solid green, it means that the rechargeable battery 18 is fully charged and the turning pillow can continue to be used.

[0025] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the protection scope of this utility model.
