Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressure sore prevention, in particular to an intelligent pressure sore prevention system and a control method. BACKGROUND

[0002] Pressure sores (also known as pressure injuries) are a serious complication faced by long-term bedridden patients, especially common in the elderly, spinal cord injury patients and intensive care patients. Pressure sores not only cause severe pain, increased risk of infection and decreased quality of life for patients, but also significantly prolong hospital stays and increase medical burden.

[0003] Traditional pressure sore prevention methods mainly rely on regular manual turning over by nursing staff (usually every 2 hours) and the use of static decompression mattress. However, manual turning over has three major core defects: 1. Insufficient compliance: night care is easily neglected, and frequency is difficult to guarantee when human resources are tight; 2. Operation risk: body position adjustment can cause secondary injury to patients or occupational strain to nursing staff; 3. Response lag: unable to sense real-time changes in local pressure, with limited prevention effect. Research has been conducted on traditional manual nursing methods, but the problem of nursing cost and fine care for pressure sore prevention has not been fundamentally solved.

[0004] There are also related products on the market for preventing pressure sores, mainly of three types: 1. Air bag type, 2. Intelligent monitoring type, 3. Material type. However, these three types of mattress products have problems: 1. Dynamic response problem: traditional air bag mattress relies on a pre-set inflation and deflation mode (such as inflation every 30 minutes), and cannot sense real-time changes in patient pressure, humidity and body temperature; 2. Individualized care problem: material type mattress can passively adapt to body shape, but cannot distinguish risk areas for different patients (such as diabetic patients who are more prone to pressure sores on the heel); 3. Data closed loop problem: intelligent monitoring type mattress can generate pressure reports, but requires manual interpretation and adjustment of the device, and cannot achieve automatic decompression function.

[0005] Therefore, it is a problem for those skilled in the art to provide an intelligent pressure sore prevention system and control method. SUMMARY

[0006] Therefore, the present application provides an intelligent pressure sore prevention system and control method to at least solve one of the technical problems mentioned in the background.

[0007] To achieve the above purpose, the present application adopts the following technical solutions: The application discloses an intelligent anti-bedsore system, which comprises a five-function nursing bed and further comprises a pressure detection mattress, a server, an industrial control screen and a controller, wherein the pressure detection mattress is arranged on the five-function nursing bed; the pressure detection mattress, the server, the industrial control screen and the controller are electrically connected in sequence, and the controller is electrically connected with lifting motor push rods, a back motor push rod, a leg motor push rod and a turning-over motor push rod of the five-function nursing bed respectively.

[0008] By adopting the above technical scheme, the application has the following beneficial effects: By adjusting the posture of the bed body through pressure detection, the pressure value of the part of the human body prone to bedsore can be effectively reduced, and the occurrence of bedsore can be reduced.

[0009] Further, the pressure detection mattress comprises flexible fabric pressure sensors and a mattress base layer which are arranged in a staggered mode and are connected, the flexible fabric pressure sensors are electrically connected with the server, and the flexible fabric pressure sensors are divided into a right scapula pressure detection area, a left scapula pressure detection area, a right elbow pressure detection area, a left elbow pressure detection area, a sacrococcygeal pressure detection area, a right hip pressure detection area, a left hip pressure detection area, a right lower leg pressure detection area, a left lower leg pressure detection area, a right heel pressure detection area and a left heel pressure detection area according to the distribution positions of the pressure sensors.

[0010] According to the control method of the above-mentioned intelligent anti-bedsore system, the flexible fabric pressure sensors can monitor the pressure threshold of each position in real time, and the detected data can be uploaded to the server through a network, the server can receive and analyze the data, and the server can issue a command for the motor push rod execution to the industrial control screen, the industrial control screen can issue an instruction to the controller, and the controller can control the corresponding motor push rod to move to change the shape of the five-function nursing bed and complete the body position adjustment.

[0011] Further, when the sacrococcygeal position pressure is detected to be high and the current body position is a supine position, a back lifting and leg lifting linkage action is performed; when the heel position pressure is detected to be high and the current body position is not a lateral position, a leg lifting action is performed until the lifting angle is 20-30°, if the current body position is a supine position, a back lifting action can be performed in linkage until the lifting angle is 20°; when the scapula position pressure is detected to be high, a left and right alternating side turning-over action is performed; when the elbow position pressure is detected to be high, a back lifting and leg lifting linkage action is performed; when the left hip position pressure is detected to be high, a right turning-over action is performed, and correspondingly, when the right hip position pressure is detected to be high, a left turning-over action is performed; when the left leg position pressure is detected to be high, a right turning-over action is performed, and correspondingly, when the right leg position pressure is detected to be high, a left turning-over action is performed; and when the pressure of multiple positions is detected to be high at the same time, a side turning-over action is first performed, the body position is kept for 5-10 minutes, then the body position is returned to a supine position, and a back lifting and leg lifting linkage action is performed.

[0012] Therefore, the intelligent anti-bedsore system and control method provided by the present application have the following beneficial effects compared with the prior art: 1) Dynamic and accurate pressure management Real-time monitoring and feedback: The pressure distribution data of the human body and the contact surface of the mattress are collected in real time by the flexible fabric pressure sensor to form a dynamic two-dimensional or three-dimensional pressure thermal map, breaking through the limitation of the traditional air bag type mattress relying on the preset mode. For example, when the pressure sensor detects that the pressure of a certain part exceeds the threshold value (such as the sacrococcygeal part), according to the size and duration of the pressure, the server issues a control instruction to the Android industrial control screen, the Android industrial control screen issues the instruction to the controller, and the controller controls the corresponding motor push rod to move, which can immediately trigger the control adjustment of the bed body, thereby completing the adjustment of the body posture and realizing the accurate control of the body part pressure. 2) Active protection closed loop: The traditional air bag type can only be passively inflated and deflated, while the present application forms a monitoring-analysis-execution closed loop. The pressure sensor captures the pressure data, the algorithm identifies the high-risk area (such as the long-time high-pressure area), and according to the analysis result, the motor adjusts the body posture and changes the pressure position. 3) Individualized adaptation capability Adapt to complex needs: Through dynamic adjustment and preset individual data information function, the angle of control of each part of the bed body can be automatically adjusted according to the weight, body shape and body position difference of different patients (obese, emaciated, postoperative, etc.), realizing the accurate adjustment of one person one scheme. 4) Comprehensive optimization of nursing efficiency Data-driven nursing decision: The pressure data can be displayed in real time through the visual interface (such as APP or medical terminal), helping medical staff to identify the high-risk area of pressure ulcers, evaluate the effect of the existing nursing plan, and develop individualized turning plan (such as adjusting the interval time to 2 hours or 3 hours). For example, the system can count the peak pressure period at night and prompt to strengthen the monitoring during this period. 5) Reduce dependence on human intervention: Traditional nursing relies on manual timed turning (every 2 hours), while the linkage technology can extend the safe turning interval to 4-6 hours through automatic pressure adjustment, reducing the nursing intensity, and can reduce the incidence of pressure ulcers by 30%-50%. 6) Make up for the defects of single technology: overcome the lack of real-time feedback of air bag type, the present application realizes dynamic adjustment through linkage sensor; overcome the insufficient active intervention of monitoring type, the present application realizes accurate control through linkage motor control; overcome the inability of material type to respond dynamically, the present application enhances adaptability through pressure sensor + body position adjustment. 7) Balance between cost and effect: Compared with the high cost of pure memory foam mattress, the motor + sensor scheme can reduce maintenance cost (such as replacing the damaged motor or sensor alone) through modular design, and its effect can be quantified (through pressure data comparison), which is better than the fuzzy effect definition of material type mattress.

[0018] Specifically, the flexible fabric pressure sensor uploads the pressure detection data to the server through a WiFi network; the industrial control screen 3 is connected with the controller through a 485 serial port; the controller is connected with the back motor push rod, the leg motor push rod and the turning-over motor push rod through a 485 serial communication mode; the back motor push rod controls the lifting of the back metal panel, and the control angle range is 0-73°; the leg motor push rod controls the lifting of the leg metal panel, and the control angle is 0-38°; the turning-over motor push rod controls the left and right folding of the middle metal panel, and the control angle is 0-20°.

[0019] The embodiment of the present application also discloses a control method according to the above-mentioned intelligent anti-bedsore system, the flexible fabric pressure sensor monitors the pressure threshold of each position in real time, and uploads the detected data to the server through a network, the server receives and analyzes these data (through algorithm analysis to obtain which part has a higher pressure value and how long the duration is), and issues a command for the motor push rod execution to the industrial control screen 3, the industrial control screen 3 issues an instruction to the controller, and the controller controls the corresponding motor push rod to move to change the shape of the five-function nursing bed (the five-function nursing bed is prior art), and complete the body position adjustment.

[0020] Specifically, when detecting that the sacrococcygeal position pressure is high, and the current body position is supine, a back-up and leg-lifting linkage action is performed, such as back-up 20° and leg-lifting 20°; when detecting that the heel position pressure is high, and the current body position is not lateral, a leg-lifting action is performed until the lifting angle is 20°-30°, and if the current body position is supine, a back-up action is linked until the lifting angle is 20°, and the leg-lifting helps to relieve the direct stress on the heel, and the heel position is not suitable for long-term direct compression, and the state should be checked at least once an hour; when detecting that the scapula position pressure is high, a left and right alternating side turning action is performed; when detecting that the elbow pressure is high, a back-up and leg-lifting linkage action is performed, such as back-up 20° and leg-lifting 20°; when detecting that the left hip pressure is high, a right turning action is performed, and correspondingly, when detecting that the right hip pressure is high, a left turning action is performed; when detecting that the left leg position pressure is high, a right turning action is performed, and correspondingly, when detecting that the right leg position pressure is high, a left turning action is performed; when detecting that multiple positions are high pressure at the same time, a side turning action is first performed, maintained for 5-10 minutes, then returned to supine, and then a back-up and leg-lifting linkage action is performed.
