Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressure sore prevention and treatment, in particular to an AI intelligent pressure sore prevention monitor. BACKGROUND

[0002] The local tissues of the body of a long-term bedridden patient are prone to blood flow obstruction under continuous pressure or shear force, leading to local inflammatory reaction and even local infection caused by external pathogenic bacteria, and thus causing tissue necrosis and pressure sores. Avoiding excessive local pressure on the skin of the patient is one of the important means of pressure sore prevention and treatment, and therefore, it is necessary to monitor and adjust the skin pressure of the bedridden patient.

[0003] Through retrieval, it is found that the prior art has some defects in actual use. Most of them directly inflate the air bag to achieve pressure sore prevention and treatment. Long-term direct inflation of the air bag, especially at high frequency or high pressure, can cause the air bag material to gradually age, harden, and even crack, thereby accelerating its fatigue damage. This not only shortens the service life of the air bag, but also may increase the risk of injury to the patient. In addition, when the equipment has poor sealing or is damaged, the values monitored by the sensor and the actual amount of inflation and deflation will differ from the predetermined values. This error can cause the equipment to be unable to accurately determine the state of the air bag, thereby failing to timely adjust the pressure or issue a warning. This inaccurate information feedback will seriously affect the safety of the patient's use.

[0004] How to invent an AI intelligent pressure sore prevention monitor to solve these problems has become a problem that needs to be solved by those skilled in the art. SUMMARY

DETAILED DESCRIPTION

[0034] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0035] Embodiment one, refer to Figures 1-6 An AI intelligent anti-bedsore monitor includes an instrument main body 1 and a mattress main body 2. The instrument main body 1 is provided with a monitoring host 10 and a control host 11. The instrument main body 1 is provided with an inflation pump (not shown in the figure). The output end of the inflation pump is connected with a gas conveying pipe 4. The monitoring host 10 is provided with a vital sign monitoring module, a bed state monitoring module, a real-time in-bed and out-of-bed monitoring module, a pressure monitoring module, a nursing reminding module, a body position monitoring module and a risk early warning module. The vital sign monitoring module, the bed state monitoring module, the real-time in-bed and out-of-bed monitoring module, the pressure monitoring module, the nursing reminding module, the body position monitoring module and the risk early warning module can monitor the patient's vital signs, bed state, body position and pressure distribution in real time. The design of the mattress main body 2 focuses on responding to these monitoring data. The mattress main body 2 is provided with an induction adjusting assembly, an early warning assembly and a damage detection assembly. The induction adjusting assembly automatically adjusts the supporting force of the mattress to reduce the risk of long-term local pressure on the patient. The early warning assembly monitors and warns the pressure state inside the induction adjusting assembly. The damage detection assembly detects whether the induction adjusting assembly is damaged. The monitoring host 10, the control host 11, the inflation pump and the induction adjusting assembly, the early warning assembly and the damage detection assembly are electrically connected. Wherein,

[0036] The vital sign monitoring module monitors the patient's respiratory rate and heart rate in real time to ensure that the patient's vital signs are within the normal range. It is suitable for patients who need continuous monitoring of vital signs, such as long-term bedridden, postoperative recovery, etc.

[0037] The bed state monitoring module monitors whether the patient is in bed and the time and frequency of getting out of bed in real time, which helps medical staff understand the patient's activity and provide necessary help and care in time.

[0038] The pressure monitoring module monitors the pressure distribution of each part of the patient's body in real time, avoids long-term local pressure leading to bedsores, and is particularly suitable for patients who are long-term bedridden, have difficulty moving, and need special body position care;

[0039] The nursing reminder module intelligently reminds medical staff to perform necessary nursing operations according to the patient's vital sign monitoring data and nursing plan, improves nursing efficiency, and ensures that the patient receives timely and effective care;

[0040] The body position monitoring module monitors the patient's body position changes in real time, including lateral recumbency, supine, prone, etc., which helps medical staff understand the patient's body position and adjust the nursing strategy in time to prevent complications such as bedsores;

[0041] The risk warning module includes bed leaving warning, stroke warning, active call, respiratory abnormality warning, heart rate abnormality warning, and bed sore risk warning. The bed leaving warning automatically issues a warning when the patient leaves the bed for too long or too frequently, reminding medical staff to pay attention. The stroke warning predicts the risk of stroke by monitoring the patient's vital signs and body changes. The active call allows the patient to actively call medical staff through the buttons on the device to seek help. The respiratory abnormality warning automatically issues a warning when the patient's breathing rate or depth is abnormal. The heart rate abnormality warning automatically issues a warning when the patient's heart rate exceeds the normal range. The bed sore risk warning predicts the risk of bedsores based on the monitoring data of the pressure monitoring module and the body position monitoring module.

[0042] Further, the mattress body 2 includes a support layer 21, an elastic expansion layer 22 fixedly connected on top of the support layer 21, and an upper cushion layer 23 laid on the elastic expansion layer 22. As the basic structure of the mattress, the support layer 21 provides the necessary stability and load-bearing capacity, which is usually made of solid and durable materials. The elastic expansion layer 22 has a certain elasticity and expansion, which can expand and contract accordingly according to the inflation and deflation of the air bag 6. The design of this layer helps to better distribute pressure and improve patient comfort. The upper cushion layer 23 is laid on the elastic expansion layer 22 and is usually made of soft and skin-friendly materials such as memory foam or latex, which provides additional comfort and breathability, and can further distribute pressure and reduce the occurrence of bedsores.

[0043] The inductive adjusting assembly comprises a gas storage tank 3, a pressure sensing layer 5, an air bag 6, a limiting cylinder 7 and a sliding plug 9. The pressure sensing layer 5 is arranged between the elastic expansion layer 22 and the upper cushion layer 23 in an array, capable of monitoring the pressure distribution of each part of the patient's body in real time. The gas storage tank 3 is fixedly arranged inside the supporting layer 21. The two sides of the gas storage tank 3 are respectively provided with an air inlet pipe 31 and an air outlet pipe 32. The upper side of the gas storage tank 3 is provided with a plurality of air guide cylinders 30. The limiting cylinder 7 is sleeved outside the corresponding air guide cylinder 30 and the lower end thereof is fixedly connected with the upper side wall of the gas storage tank 3. The sliding plug 9 is slidably sleeved outside the corresponding air guide cylinder 30. The top of the limiting cylinder 7 is provided with a notch for the sliding plug 9 to slide. The electromagnetic valve 301 is installed in the inside of the air guide cylinder 30. The air bag 6 is fixedly arranged on the top of the sliding plug 9. The lower side of the sliding plug 9 and the air bag 6 is provided with a gas guide hole. The inner cavity of the limiting cylinder 7 is fixedly connected with the connecting spring 71. The lower end of the connecting spring 71 is fixedly connected with the lower part of the sliding plug 9. The input end of the control host 11 is electrically connected with each pressure sensing layer 5. The output end of the control host 11 is electrically connected with the air pump and each electromagnetic valve 301. When the control host 11 receives the signal transmitted by the pressure sensing layer 5, it will calculate the air bag 6 and the air volume required for adjustment according to the preset algorithm, and then control the inflow or outflow of the gas in the corresponding air bag 6 through the electromagnetic valve 301. When the control host 11 issues an instruction, the electromagnetic valve 301 will be opened or closed, thereby allowing or preventing the gas to enter or leave the air bag 6 through the air guide cylinder 30.

[0044] It should be noted that the pressure sensing layer 5 is a weavable pressure sensing material. The weavable pressure sensing material is an ultra-thin textile material capable of converting pressure into measurable electrical signals, similar to the way the skin senses pressure. This material has high sensitivity and plasticity, can be washed and cut, has the characteristics of lightness, thinness and softness, is convenient to arrange and cover on various surfaces, and has great flexibility and customizability in application. A plurality of micro pressure sensors are arranged in the pressure sensing layer 5 in an array. When the patient presses the surface of the pressure sensing layer 5, the micro pressure sensors inside the pressure sensing layer 5 will detect the change in pressure and generate corresponding electrical signals. These electrical signals will be converted into data to generate a three-dimensional pressure distribution map through the monitoring host 10, the control host 11 and the data processing algorithm. The pressure sensing material collects pressure data at different points through the built-in multiple micro pressure sensors. The sensor array transmits the pressure data of these points to the central processing unit of the instrument body 1 for real-time calculation and processing. After processing the collected pressure data, an image pressure distribution map is generated, in which the color and height reflect the pressure intensity of different regions. The pressure points and pressure intensity are distinguished by red and green in the graph (not shown in the drawings).

[0045] Further, the air guide cylinder 30, the air inlet pipe 31 and the air outlet pipe 32 are all in communication with the inner cavity of the gas storage tank 3, the micro pressure sensor is arranged in one-to-one correspondence with the air bag 6, the end of the air inlet pipe 31 is in communication with the air conveying pipe 4, and the design of the gas storage tank 3 enables the gas to be rapidly distributed into each air bag 6 when needed, the safety valve 321 is installed on the air outlet pipe 32, and the sliding plug 9 is in sliding sealing connection with the corresponding air guide cylinder 30.

[0046] It should be noted that the section of the limiting cylinder 7 is in L-shaped arrangement, and the section of the sliding plug 9 is in U-shaped arrangement, when the electromagnetic valve 301 is opened, the air bag 6 will be inflated, which can make the air bag 6 swell on the one hand, and the swollen air bag 6 will drive the sliding plug 9 to move and slide in the limiting cylinder 7 on the other hand, when the air bag 6 needs to be inflated, the sliding plug 9 will move upward and compress the connecting spring 71, when the air bag 6 needs to be deflated, the sliding plug 9 will move downward, and the connecting spring 71 will drive it to reset, through the above process, the direct gas pressure borne by the air bag 6 can be secondarily buffered, and the situation that the air bag 6 is fatigue damaged due to long-term stress is reduced.

[0047] In the embodiment, the air bag 6 is in an uninflated state, the sliding plug 9 is located at a lower position of the limiting cylinder 7 under the action of the connecting spring 71, the air guide cylinder 30, the air inlet pipe 31 and the air outlet pipe 32 are all in communication with the inner cavity of the gas storage tank 3, but the electromagnetic valve 301 is in a closed state to prevent the gas from flowing unnecessarily.

[0048] The inflation process is as follows: when the monitoring host 10 detects that the pressure of a part of the patient's body exceeds the preset threshold value through the pressure sensing layer 5, the control host 11 calculates the air bag 6 and the inflation amount thereof that need to be adjusted, sends an opening instruction to the corresponding electromagnetic valve 301, and after the electromagnetic valve 301 is opened, the gas in the gas storage tank 3 flows into the corresponding air bag 6 through the air inlet pipe 31 and the air guide cylinder 30, along with the inflation of the air bag 6, the volume of the air bag 6 gradually increases, and the sliding plug 9 is driven to slide upward in the limiting cylinder 7, the upward movement of the sliding plug 9 compresses the connecting spring 71 and stores a certain elastic potential energy, at the same time, the swelling of the air bag 6 improves the support force of the part and disperses the pressure borne by the patient's body.

[0049] Pressure regulation and stabilization: along with the inflation of the air bag 6, the pressure sensing layer 5 continues to monitor the pressure change of the part, when the pressure decreases to a preset range, the control host 11 sends a closing instruction to the electromagnetic valve 301 to stop inflation, at this time, the air bag 6 remains in a certain inflation state and provides stable support force.

[0050] Deflation process: when it is necessary to reduce the supporting force of the air bag 6 (for example, after a long time of lying down or a change in patient position), the control host 11 sends an opening instruction to the electromagnetic valve 301 (or changes its state to allow gas to flow out), and after the electromagnetic valve 301 is opened, the gas in the air bag 6 flows out through the gas guide cylinder 30 into the gas storage tank 3. As the air bag 6 deflates, its volume gradually decreases, and the sliding plug 9 slides downward to the initial position or close to the initial position under the push of the connecting spring 71. The reset process of the connecting spring 71 releases the previously stored elastic potential energy, which helps the air bag 6 deflate quickly and recover.

[0051] Secondary buffering effect: the sliding of the sliding plug 9 in the limiting cylinder 7 and the compression and reset process of the connecting spring 71 actually play a secondary buffering effect on the direct gas pressure on the air bag 6, which reduces the risk of fatigue damage to the air bag 6 due to long-term stress and prolongs its service life. At the same time, this buffering effect also helps to improve the overall comfort and stability of the mattress body 2.

[0052] In summary, the AI intelligent anti-bedsores monitor can monitor the pressure distribution on each part of the patient's body in real time through the instrument body 1, the mattress body 2, the monitoring host 10 and the control host 11, and automatically adjust the inflation amount of the air bag 6 as needed to provide personalized support. The design of the sliding plug 9 and the connecting spring 71 further enhances the durability and comfort of the mattress, providing a secondary buffering effect on the direct gas pressure on the air bag 6, which reduces the risk of fatigue damage to the air bag 6 due to long-term stress and provides safer and more effective anti-bedsores care for patients. Using pressure sensors, high-risk areas on the bed that may cause pressure injuries can be identified. Through continuous data monitoring and recording, the effectiveness of nursing work (such as turning over and massage) can be quantified. Based on actual data analysis, nursing programs can be optimized and adjusted to provide more accurate and personalized care plans. Through continuous monitoring of pressure distribution, real-time identification and display of pressure hotspots can assist nursing staff in making timely adjustments, and AI algorithms can be used for deep data analysis and prediction to improve nursing quality and effectiveness.

[0053] In the second embodiment, referring to Figures 3-8 , the warning assembly includes a scale rod 8 and a sensing collar 81. The scale rod 8 is fixedly arranged on the top wall of the gas storage tank 3, and a reading is marked on the scale rod 8 to indicate the position of the sensing collar 81, thereby reflecting the state of the sliding plug 9 and the air bag 6. The sliding plug 9 is provided with a sliding groove 93 matched with the scale rod 8 and a mounting groove 94 matched with the sensing collar 81. The sensing collar 81 is fixedly arranged in the mounting groove 94 and is slidably sleeved on the outside of the scale rod 8. The sensing collar 81 and the scale rod 8 are electrically connected with the control host 11, and the reading on the scale rod 8 is fed back to the control host 11 in real time.

[0054] In this embodiment, when the sliding plug 9 slides in the limiting cylinder 7, the movement of the sliding plug 9 drives the sensing collar 81 to slide along the scale rod 8, at which time the reading on the scale rod 8 changes. The control host 11 pre-sets a reasonable movement range of the sensing collar 81 on the scale rod 8 when the air bag 6 is normally inflated. When the sensing collar 81 moves to a certain pre-set position (for example, close to the upper end) of the scale rod 8 and the duration exceeds the pre-set threshold, the control host 11 judges that the air pressure inside the air bag 6 is too large. At this time, the control host 11 triggers a pre-warning mechanism to remind medical staff to check and adjust through sound and light alarms, display screen prompts and other ways. After receiving the pre-warning information, the medical staff should immediately check whether there is sealing abnormality in the gas storage tank 3, the electromagnetic valve 301 and other components. If abnormality is found, the relevant components should be adjusted or replaced in time to ensure the normal operation of the equipment and the safety of the patient.

[0055] The pre-warning assembly provides timely and effective troubleshooting and adjustment means for medical staff by monitoring the state of the sliding plug 9 and the air bag 6 in real time and triggering a pre-warning mechanism in abnormal conditions, which not only improves the reliability and safety of the equipment, but also ensures that the patient can receive continuous and stable anti-bedsore care.

[0056] Embodiment three, refer to Figures 4-7 The damage detection assembly includes a mounting layer 91 and a gas leakage sensor 92. The mounting layer 91 is arranged at the top of the sliding plug 9, and the gas leakage sensor 92 is fixedly arranged in the mounting layer 91. The gas leakage sensor 92 is connected by a plurality of annular protruding sheet sensors to ensure comprehensive and accurate detection range. The protruding part of the gas leakage sensor 92 abuts against the bottom wall of the air bag 6 to realize accurate sensing of air pressure. The gas leakage sensor 92 is electrically connected with the control host 11, and the gas leakage sensor 92 transmits pressure readings to the control host 11.

[0057] In this embodiment, when the air bag 6 is in good condition, the internal air pressure is stable and uniformly distributed. At this time, the bottom of the air bag 6 directly acts on the protruding part of the gas leakage sensor 92, and the pressure sensed by the gas leakage sensor 92 is within the pre-set normal range. The gas leakage sensor 92 transmits the sensed pressure readings to the control host 11 in real time, and the control host 11 judges the air pressure state and integrity of the air bag 6 according to the received pressure readings.

[0058] Damage detection mechanism: when the air bag 6 is damaged, the internal air pressure will no longer be stable, and air pressure may leak at the damaged part. The gas leakage sensor 92 can sensitively capture the change of air pressure. In particular, when the pressure of the contact area between the bottom of the air bag 6 and the gas leakage sensor 92 suddenly decreases, it indicates that the air bag 6 may be damaged. The control host 11 judges the damage of the air bag 6 according to the change of pressure readings transmitted by the gas leakage sensor 92, and triggers the corresponding pre-warning mechanism.

[0059] Pre-warning and countermeasures: once the control host 11 judges that the air bag 6 is damaged, the pre-warning mechanism will be triggered immediately, reminding the medical staff through sound and light alarm, display screen prompt and other ways, and the medical staff should check the damage of the air bag 6 immediately after receiving the pre-warning information, and take necessary maintenance or replacement measures to ensure the normal operation of the equipment and the safety of the patient.

[0060] The damage detection assembly accurately senses the change of the air pressure in the air bag 6 through the air leakage sensor 92, realizes real-time monitoring of the integrity of the air bag 6, and when the air bag 6 is damaged, the component can quickly trigger the pre-warning mechanism to provide timely and effective troubleshooting and adjustment means for medical staff, which not only improves the reliability and safety of the equipment, but also ensures that the patient can receive continuous and stable anti-bedsore care.
