Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and in particular to a prone pressure sensing mat. Background Technology
[0002] In the field of ophthalmology, silicone oil tamponade is a common and important treatment. However, patients need to strictly adhere to the prone position after the procedure. This is because a correct prone position helps maintain stable intraocular pressure, promotes retinal reattachment, and ensures good adhesion of the silicone oil to the retina, thereby improving the success rate of the surgery and reducing the occurrence of complications.
[0003] However, in actual nursing care, patients often become fatigued from maintaining a prone position for extended periods. When asleep or with low compliance, they frequently change their posture unconsciously, such as leaving the prone position mat, allowing their lower back to collapse, or compressing their abdomen. These incorrect postures can all negatively impact eye recovery. Furthermore, traditional prone position mats have a single function, providing only basic support and failing to monitor the patient's prone position in real time. This makes it difficult for medical staff to promptly detect and correct postural errors, increasing the risk of postoperative complications.
[0004] Therefore, this application provides a prone pressure-sensing mat to meet the requirements. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a prone position pressure sensing mat to solve the problem that existing prone position mats cannot monitor in real time whether the patient has left the mat or has incorrect postures such as lumbar collapse or abdominal pressure, which makes it difficult for medical staff to intervene in time and increases the risk of postoperative complications.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A prone pressure-sensing pad includes a base, a lying board fixed to the top of the base, a prone pad laid on the upper surface of the lying board, a head ring pad and a plurality of adjustable horizontal support pads arranged sequentially on the upper surface of the prone pad, the internal skeleton structure of the support pad includes a base plate, a plurality of pressure sensors fixed to the upper surface of the base plate, a fixing plate mounted on the top of the plurality of pressure sensors, and a soft pad fixed to the upper surface of the fixing plate.
[0008] An alarm is fixed to one end of the reclining board near the head ring pad. The alarm is communicatively connected to a pressure sensor. A fixing frame is fixed to the other end of the reclining board. A roll is rotatably installed inside the fixing frame, and a disposable film is wound onto the roll.
[0009] Optionally, the support pad includes a chest pad, an iliac crest pad, a concave positioning pad, and a prone leg pad.
[0010] Optionally, vertical side plates are symmetrically fixed on both sides of the substrate, a horizontal limiting plate is fixed on the inner side of the side plate, and a limiting groove is provided on the side of the pad for the limiting plate to be horizontally inserted.
[0011] Optionally, a positioning hole is provided at the bottom of the side plate, and a positioning bolt is threaded through the positioning hole. The positioning bolt abuts against the outer side wall of the pad to fix the position of the support pad.
[0012] Optionally, the pressure sensors are arranged according to the functional zones of the support pad, and the threshold values of the pressure sensors in each zone are set independently.
[0013] Optionally, the threshold values of the pressure sensors in each zone are dynamically set based on an ergonomic model:
[0014] The alarm threshold for the chest pad is set at an upper limit of 60% of the patient's body weight and a lower limit of 15% of body weight.
[0015] The lower limit of the alarm threshold for the iliac crest pad is 25% of body weight. When the pressure detection is consistently less than the lower limit and the pressure sensor detects more than 5 kg, it is determined to be a lumbar collapse and incorrect posture.
[0016] The concave positioning pad is designed with a safety range of 0-2kg, and exceeding the upper limit is considered as abdominal pressure.
[0017] Optionally, the alarm device integrates a wireless transmission module and interconnects with a mobile terminal to work with the pressure sensor to monitor the user's prone position.
[0018] Optionally, the alarm is equipped with a buzzer, and the back of the alarm is equipped with an inspection cover.
[0019] Compared with the prior art, this utility model has at least the following beneficial effects:
[0020] In the above solution, the adjustable support pads can not only adjust the support position according to the patient's needs and improve the comfort of the prone position, but also identify dangerous postures such as lumbar collapse and chest compression and provide active reminders and warnings to avoid the problem of patient position failure.
[0021] In the above solution, the disposable film can be quickly covered on the mat using a roll and a retractable disposable film, thereby ensuring medical hygiene and improving medical efficiency.
[0022] In summary, when used on patients after silicone oil filling surgery, this device not only provides a comfortable lying position but also detects and reminds them of their posture, which helps improve medical outcomes and reduce the risk of postoperative complications.

[0036] like Figure 1 As shown, an embodiment of this utility model provides a prone pressure-sensing pad, including a base 1, a lying board 2, and a prone pad 3. Specifically, the lying board 2 is fixed to the top of the base 1, and the prone pad 3 is laid on the upper surface of the lying board 2. The prone pad 3 is characterized in that a head ring pad 4 and a plurality of adjustable horizontal support pads are arranged sequentially along the horizontal direction on the upper surface of the prone pad 3. The skeleton structure inside the support pad includes a base plate 9, a plurality of pressure sensors 11 are fixed to the upper surface of the base plate 9, a fixing plate 10 is installed on the top of the plurality of pressure sensors 11, and a soft pad 1001 is fixed to the upper surface of the fixing plate 10.
[0037] An alarm 12 is fixed to one end of the reclining board 2 near the head ring pad 4. The alarm 12 is connected to the pressure sensor 11. A fixing frame 13 is fixed to the other end of the reclining board 2. A roll 14 is rotatably installed inside the fixing frame 13. A disposable film is wound on the roll 14.
[0038] In actual use, the patient lies prone on the prone pad 3 with their head placed inside the head ring pad 4, which is a ring-shaped sponge pad that can automatically adjust to the shape of the patient's head to provide comfortable support.
[0039] The patient's chest, iliac crest, abdomen, and legs come into contact with the corresponding support pads in sequence.
[0040] During treatment, pressure sensor 11 collects pressure data from each area in real time and transmits it to alarm 12 via wireless module. If the patient's position is incorrect, causing the pressure value to exceed a preset threshold and last for a preset duration, alarm 12 immediately alerts medical staff via buzzer 1201 and mobile terminal. After treatment, the disposable film is removed and rolled back into roll 14, and the surface of the mat 3 is disinfected before use for the next patient.
[0041] In summary, this device, through the combination of zoned pressure monitoring and adjustable support structure, not only improves the comfort of prone position treatment but also provides proactive warnings of incorrect positioning, effectively reducing the risk of postoperative ophthalmic complications. At the same time, its convenient hygiene and maintenance design improves medical efficiency.
[0042] In the above solution, the adjustable support pads can not only adjust the support position according to the patient's needs and improve the comfort of the prone position, but also identify dangerous postures such as lumbar collapse and chest compression and provide active reminders and warnings to avoid the problem of patient position failure.
[0043] In the above solution, the disposable film can be quickly covered on the mat 3 using the roll 14 and the rolled disposable film, thereby ensuring medical hygiene and improving medical efficiency.
[0044] In summary, when used on patients after silicone oil filling surgery, this device not only provides a comfortable lying position but also detects and reminds them of their posture, which helps improve medical outcomes and reduce the risk of postoperative complications.
[0045] In one specific embodiment, the surface of the lying board 2 is covered with a waterproof and breathable fabric, which is a polytetrafluoroethylene microporous membrane composite fabric. The lying pad 3 is fixed to the top of the lying board 2 by Velcro. The Velcro has a male side and a female side. The male side is sewn to the bottom of the lying pad 3, and the female side is pasted to the surface of the lying board 2, which facilitates the removal and cleaning of the lying pad 3. The Velcro does not affect the sliding of the support pad along the limiting groove 301.
[0046] The upper surface of the prone mat 3 is arranged in a horizontal direction with a head ring pad 4 and multiple support pads. The support pads include a chest pad 5, an iliac crest pad 6, a concave body position pad 7, and a prone leg pad 8. Each support pad is designed to be adjustable in horizontal position.
[0047] like Figure 2 and Figure 3 As shown, taking the prone leg pad 8 as an example, its frame structure includes a base plate 9, which is a rectangular aluminum alloy plate with high strength and light weight. Vertical side plates 901 are symmetrically fixed on both sides of the base plate 9. The side plates 901 are connected to the base plate 9 by welding to ensure a firm connection. A horizontal limiting plate 902 is welded to the inner side of the side plate 901. The limiting plate 902 and the corresponding limiting groove 301 on the side of the prone leg pad 3 form a sliding fit to achieve horizontal position adjustment of the prone leg pad 8.
[0048] Meanwhile, a positioning hole 903 is provided at the bottom of the side plate 901. The positioning hole 903 is a threaded hole, and a positioning bolt 904 passes through its internal thread. When the prone leg pad 8 slides to the target position, the positioning bolt 904 is rotated so that its end abuts against the outer wall of the prone pad 3, and the position of the prone leg pad 8 is fixed by friction.
[0049] Multiple pressure sensors 11 are fixed to the upper surface of the substrate 9 by silicone bonding. The pressure sensors 11 can be, but are not limited to, thin-film pressure sensors. The pressure sensors 11 are arranged according to the functional zones of each support pad. For example, in this embodiment, six pressure sensors 11 are arranged in the chest pad 5 area, four pressure sensors 11 in the iliac crest pad 6 area, five pressure sensors 11 in the concave positioning pad 7 area, and five pressure sensors 11 in the prone leg pad 8 area. A fixing plate 10 is mounted on the top of each zone's pressure sensors 11. The fixing plate 10 is a rigid plastic plate, and its surface is covered with a memory foam pad 1001 of a certain thickness. The memory foam pad 1001 has slow rebound characteristics and can automatically adjust its shape according to the patient's body pressure, improving contact comfort.
[0050] Cooperate Figure 3 and Figure 4 As shown, an alarm 12 is fixed at one end of the reclining board 2 near the head ring pad 4. The alarm 12 has a built-in wireless transmission module that can be wirelessly connected to the pressure sensor 11 and can also be wirelessly interconnected with the mobile phone or monitor of medical staff to realize remote data transmission.
[0051] The alarm 12 is equipped with a buzzer 1201, which is a piezoelectric buzzer. When the pressure sensor 11 detects an abnormal pressure value, the buzzer 1201 emits a continuous alarm sound at a frequency of 2kHz for 10 seconds to alert medical personnel. A maintenance cover 1202 is located on the back of the alarm 12. The maintenance cover 1202 is fixed to the back of the alarm 12 with four small screws. Opening the maintenance cover 1202 allows for easy replacement of the battery or repair of the internal circuitry.
[0052] Meanwhile, a fixing frame 13 is welded to the other end of the lying board 2. The fixing frame 13 has a horizontal "L" shaped structure. A roller 14 is rotatably installed inside the fixing frame 13. A disposable film is wound on the roller 14. The disposable film is made of polyethylene and has good flexibility and waterproof properties.
[0053] In this specific implementation, the threshold setting of the pressure sensor 11 is dynamically adjusted based on an ergonomic model: the upper limit of the alarm threshold for the chest pad 5 is 60% of the patient's weight, and the lower limit is 15% of the weight. For example, for a patient weighing 70kg, an alarm is triggered when the pressure of the chest pad 5 exceeds 42kg or falls below 10.5kg; the lower limit of the alarm threshold for the iliac crest pad 6 is 25% of the body weight. When the pressure detection is consistently below the lower limit and the pressure sensor 11 detects a value greater than 5kg, it is determined to be an incorrect posture with lumbar collapse. At this time, the alarm device 12 issues an intermittent alarm with an interval of 1 second; the concave positioning pad 7 is set with a safety range of 0-2kg. When the pressure exceeds 2kg, it is determined to be abdominal pressure, and the alarm device 12 immediately issues a high-frequency alarm with a frequency of 3kHz. In addition, the pressure sensor 11 of the prone leg pad 8 is used to monitor the leg's unsupported state. When the detected value is below 3kg, it indicates insufficient leg support, and the alarm device 12 issues a low-frequency alarm with a frequency of 1kHz.
[0054] The working principle of the technical solution provided by this utility model is as follows:
[0055] In actual use, the patient lies prone on the prone pad 3 with their head placed inside the head ring pad 4, which is a ring-shaped sponge pad that can automatically adjust to the shape of the patient's head to provide comfortable support.
[0056] The patient's chest, iliac crest, abdomen, and legs sequentially contact the corresponding support pads. Medical staff adjust the position of each support pad according to the patient's body size. For example, for taller patients, the chest pad 5 and prone leg pad 8 can be slid outwards to ensure the support points are aligned with key body parts. During adjustment, first loosen the positioning bolt 904, push the support pad to the appropriate position, and then tighten the positioning bolt 904 to secure it. After adjustment, a disposable film is placed over the surface of the prone pad 3 to effectively isolate the patient's bodily fluids and prevent cross-infection.
[0057] During treatment, pressure sensor 11 collects pressure data from each area in real time and transmits it to alarm 12 via wireless module. If the patient's lumbar region collapses due to fatigue, and the pressure on iliac crest pad 6 drops below 25% of body weight for more than 5 seconds, while the pressure value is greater than 5 kg, alarm 12 immediately alerts medical staff via buzzer 1201 and mobile terminal. After treatment, the disposable film is removed and rolled back into roll 14, and the surface of the supine pad 3 is disinfected before use for the next patient.
[0058] In summary, this device, through the combination of zoned pressure monitoring and adjustable support structure, not only improves the comfort of prone position treatment but also provides proactive warnings of incorrect positioning, effectively reducing the risk of postoperative ophthalmic complications. At the same time, its convenient hygiene and maintenance design improves medical efficiency.
