Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, more specifically, particularly relates to an acupoint massage pressure ulcer prevention device for sacrococcygeal skin monitoring. BACKGROUND

[0002] Pressure ulcers, also known as pressure injuries, are caused by long-term pressure, shear force or friction on local tissues, combined with factors such as local moisture and malnutrition, leading to blood circulation disorders, tissue ischemia and hypoxia, and further causing skin and subcutaneous tissue damage. They often occur in the sacrococcygeal region, hip, heel and other bony prominences, and are characterized by skin redness, blisters, ulcers and even deep tissue necrosis. They are commonly seen in long-term bedridden, sedentary and mobility-restricted populations. They can be effectively prevented and intervened through regular decompression, maintaining skin cleanliness and dryness, and improving nutrition.

[0003] Current pressure ulcer prevention devices have at least the following problems: First, in nursing homes, family care settings and hospital geriatric departments, long-term bedridden or sedentary elderly populations need to maintain a fixed posture for a long time. The sacrococcygeal region, as the main stress area, is often in a state of continuous pressure. Current devices for supporting the sacrococcygeal region of the elderly can provide basic support, but they are generally characterized by fixed support points, making it difficult to dynamically adjust the stress position. In addition, the lack of flexible cushioning design in the material of some support components can cause friction when they come into direct contact with the relatively fragile skin of the elderly population. The above situations can lead to long-term obstruction of blood circulation in the sacrococcygeal region of the elderly, insufficient oxygen supply to the tissues, and an increased risk of pressure ulcers. Direct friction between the skin and the support components can also cause damage to the surface layer of the elderly skin, further reducing the skin's resistance to damage, affecting the comfort of the elderly, and increasing the burden on caregivers, prolonging the recovery period of the elderly.

[0004] Second, in the elderly care scene, especially the elderly group of long-term bedridden, paralyzed or with urinary incontinence problems, the sacrococcygeal part is prone to sweat accumulation due to lack of activity and poor local ventilation. At the same time, some old people may have urinary incontinence due to decreased self-urinary control ability, resulting in long-term wet skin in the sacrococcygeal part. The current treatment for the sacrococcygeal part is to rely on artificial regular replacement of nursing pads, application of talcum powder and other means. However, artificial nursing has the limitation of lack of real-time performance, which is difficult to continuously monitor and timely improve the sacrococcygeal part wetness. Moreover, the drying effect of talcum powder and other products is limited, which cannot fundamentally solve the continuous existence of the wet environment. This long-term wet state can damage the original barrier function of the skin of the elderly, reduce the resistance of the skin to external stimuli, easily cause inflammatory reactions such as skin redness and itching, and further increase the probability of skin damage and pressure ulcers, resulting in additional physical discomfort in the elderly group, and increasing the frequency and difficulty of nursing work, affecting the overall nursing efficiency and quality.

[0049] Working principle: Firstly, the user sits steadily by the help of the handles on both sides of the nursing bed 1, and the soft seat cushion on the surface of the seat can preliminarily relieve the body compression and improve the initial comfort. Then, the device control end presets the supporting force according to the body weight of the elderly and the skin condition of the sacrococcygeal region, so as to avoid damaging the skin due to over-tight supporting or failing to take effect due to over-loose supporting. After the presetting is completed, the miniature air pump 7 is started, which draws clean air from the outside, uniformly delivers it to each support air bag 3 through the connecting pipeline 6 in the installation frame 13. Since a layer of flexible supporting material is covered on the top of the support air bag 3, the air bag can avoid directly rubbing the skin of the elderly during the inflation process, and at the same time, it can buffer the impact feeling during the inflation. When the air pressure in the support air bag 3 reaches the preset value, the pressure sensor feeds back the signal, and the miniature air pump 7 automatically reduces the working power and turns to the stable pressure mode, so as to ensure that the support air bag 3 can gently lift the sacrococcygeal region at this time, laying a foundation for the subsequent cyclic supporting.

[0050] ​Second step, after the device enters the cycle support stage, the screw rod connected with the motor starts to move alternately, driving the sliding block 10 to reciprocate in the sliding groove on both sides of the installation frame 13, and the sliding block 10 is fixed symmetrically with the air bag pressing plate 8, so the air bag pressing plate 8 moves synchronously along the lower side of the supporting air bag 3, and the pressing block at the lower end of the air bag pressing plate 8 continuously presses the lower end of the supporting air bag 3, so that the upper end of the air bag expands towards the sacrococcygeal part, realizing the dynamic transformation of the support point, avoiding the blood circulation being blocked due to long-term pressure on the same part, at the same time, the massage rollers 9 on both sides of the air bag pressing plate 8 have a diameter larger than the thickness of the pressing plate, so that when rolling, they generate stronger pressure on the corresponding supporting air bag 3, prompting the massage top block 4 on the air bag to carry the massage pressing plate to protrude, accurately adhere to the sacrococcygeal part acupoint for soft pressing, and promote local blood circulation during repeated massage process, further reducing the risk of pressure sores.

[0051] Third step, the humidity sensor on the surface of the massage top block 4 contacts the sacrococcygeal skin in real time, accurately monitors the humidity changes caused by sweating, incontinence and the like, when the detected humidity exceeds the preset threshold, the sensor immediately sends a signal to the electromagnetic one-way valve 17 on the air flow conveying pipeline 18, the electromagnetic one-way valve 17 quickly opens the valve, at this time, the excess air in the supporting air bag 3 flows through the air flow conveying pipeline 18, the sealing sleeve 19 outside the pipeline cooperates with the air transmission inner tube 11, even if the air bag pressing plate 8 reciprocates, it can ensure that the air passage is not interrupted, finally the air enters the air heating cavity 14 in the air bag pressing plate 8, the heating plate 15 in the cavity heats the air to an appropriate temperature of 30-35℃, the dry warm air after heating is blown out from the air outlet 12 above the heating plate 15, and the air outlet 12 moves with the air bag pressing plate 8, which can cover the sacrococcygeal area comprehensively, at the same time, the miniature air pump 7 synchronously increases the power to supplement the lost air in the supporting air bag 3, ensuring that the supporting force is always stable, drying without affecting the supporting effect, reducing the risk of pressure sores from the environmental level.

[0052] In the fourth step, when the user goes out for activities during the day, the portable monitoring plate 22 is fixed to the sacrococcygeal part by the buckle and the card seat through the length adjustment of the spring reel on both sides. The flexible skin-friendly material closely adheres to the skin without affecting daily activities. The multiple ultrasonic sensors 23 arranged in the portable monitoring plate 22 work continuously to collect information related to the sacrococcygeal skin and store it in the built-in module. After the user returns to the nursing bed 1, the electronic interface at the back of the portable monitoring plate 22 is connected to the information transmission interface on the monitoring device support 21, and the charging and data transmission functions are realized synchronously. The information collected during the day is quickly transmitted to the core control unit of the monitoring device support 21. After receiving the data, the monitoring device support 21 automatically analyzes and locates the subcutaneous fat weak area, blood circulation prone to blockage area, and corresponding core acupoints. Then, the needle point massage mechanism 20 is sent a targeted control instruction: for the acupoints corresponding to the key risk areas, the needle point massage mechanism 20 is started for intensive massage action, and for the areas with lower risk, the basic massage mode is maintained. At the same time, the monitoring device support 21 fuses the dynamic data of the portable monitoring plate 22 with the real-time data of other sensors on the nursing bed 1. If it is found that the key areas are under abnormal pressure, the corresponding support air bag 3 is adjusted by the linkage circulation support mechanism. If the skin is found to be wet, the drying mechanism is triggered to start ventilation, forming a closed loop of dynamic monitoring during the day, accurate data analysis, acupoint targeted massage, and multi-module collaborative intervention, which maximizes the effect of pressure ulcer prevention.
