Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a smart-controlled multifunctional medical air cushion. Background Technology
[0002] Currently, the prevention of pressure injuries in critically ill patients in clinical practice, both domestically and internationally, largely relies on regular manual repositioning. This leads to high labor intensity and low efficiency in nursing care, increasing the time and economic costs of patient recovery. For pressure injury care, the most effective approach is prevention. Intelligent technologies can assist nurses in damage monitoring and pressure control, enabling early intervention, prevention, and treatment to avoid pressure injuries at their source. Existing nursing mattresses are mostly designed for supine positions and cannot automatically change the patient's lying position. For patients with limited mobility who cannot turn to their side, additional caregivers are still required to regularly turn them and change their positions to prevent muscle atrophy and pressure injuries caused by prolonged fixed postures. This is extremely inconvenient and increases manpower burden. Patients who are bedridden for extended periods and unable to change position independently are highly susceptible to pressure injuries due to prolonged pressure on localized skin during long-term bed rest treatment, severely impacting their treatment. To alleviate the distress and suffering of patients with limited mobility and those who are bedridden for extended periods, and to reduce the workload of caregivers, research on related medical devices remains a key focus and a challenge in the industry. Summary of the Invention
[0003] In view of the problems existing in the background technology, the purpose of this invention is to provide a smart-controlled multifunctional medical air cushion. By inflating and deflating different airbags, the air cushion can be positioned to tilt to the left or right, raise the backrest, etc., allowing patients who are bedridden for extended periods to change positions. This is convenient to use, increases patient comfort, and prevents various complications such as pressure injuries caused by prolonged lying down with little movement. Furthermore, all airbags in this air cushion are individually controlled, allowing for sufficient deflation of airbags on wounds and other areas that cannot bear pressure during prone ventilation therapy and repositioning therapy, ensuring the effectiveness of the treatment.
[0004] To achieve the above objectives, the present invention provides a multifunctional medical air cushion with intelligent control, comprising an air cushion body, an outer cover, and a controller; the air cushion body is disposed within the outer cover, and the air cushion body includes a horizontal airbag area, a lifting airbag area, and a tilting airbag area, wherein the horizontal airbag area is provided with a layer of strip-shaped airbags arranged along the length direction, the number of strip-shaped airbags in the layer being 12; the lifting airbag area is adjacent to the horizontal airbag area and is provided with two layers of strip-shaped airbags arranged along the length direction, the upper layer containing 8 strip-shaped airbags and the lower layer containing 8 strip-shaped airbags; the tilting airbag area is disposed below the horizontal airbag area and the lifting airbag area, and is provided with a layer of square airbags arranged along the width direction. The system comprises two square airbags; each airbag is connected to the others by a retaining clip; the outer cover of the airbag is equipped with a gas interface and a power interface, the gas interface being connected to an air pump; each airbag is equipped with an inlet valve and an outlet valve, the inlet valve and outlet valve being connected to the gas interface via a connecting hose; each airbag is equipped with a pressure sensor; the inlet valve, outlet valve, and pressure sensor are connected to the power interface via cables; the controller is electrically connected to the air pump, inlet valve, outlet valve, and pressure sensor; flexible sensors for monitoring vital signs are installed in the horizontal airbag area and the lifting airbag area, and are electrically connected to the controller; the flexible sensors are located at the sacrum, coccyx, heel, occipital region, scapula, and olecranon process of the elbow joint.
[0005] In one embodiment, the flexible sensor is also disposed on the greater trochanter, auricle, lateral ribs, and acromion; the flexible sensor is disposed on the anterior superior iliac spine, sternum / costal arch, knee, and dorsum of the foot / toes; the flexible sensor is disposed on the ischial tuberosity, inferior angle of the scapula, spinous process of the spine, and heel.
[0006] In one embodiment, each airbag is provided with a manual deflation valve, which is located on the outer cover.

[0030] Unless the context requires otherwise, throughout the specification and claims, the word “comprising” and its variations, such as “including” and “having”, shall be understood to have an open, inclusive meaning, that is, to be interpreted as “including, but not limited to”.
[0031] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.
[0032] In the following description, in order to clearly demonstrate the structure and operation of the present invention, a number of directional terms will be used. However, terms such as "left," "right," "up," and "down" should be understood as convenient terms and not as limiting terms.
[0033] The following description, with reference to the accompanying drawings, details the intelligently controlled multifunctional medical air cushion of the present invention. Figures 1 to 9 The intelligent control multifunctional medical air cushion according to the present invention includes an air cushion body 1, an outer cover 2, and a controller 3. The air cushion body 1 is disposed inside the outer cover 2. The air cushion body 1 includes a horizontal airbag area 11, a lifting airbag area 12, and a tilting airbag area 13. The horizontal airbag area 11 is provided with a layer of strip-shaped airbags arranged along the length direction, and the number of strip-shaped airbags in the layer is 12. The lifting airbag area 12 is adjacent to the horizontal airbag area 11 and is provided with two layers of strip-shaped airbags arranged along the length direction, with 8 strip-shaped airbags in the upper layer and 8 strip-shaped airbags in the lower layer. The tilting airbag area 13 is disposed below the horizontal airbag area and the lifting airbag area and is provided with a layer of square airbags arranged along the width direction, and the number of square airbags in the layer is 2. The airbags are connected by a retaining clip. The air cushion outer cover 2 is provided with a gas interface 21 and a power interface 22. Figures 1 to 3 The gas interface 21 and power interface 22 shown are located on one side of the airbag. The present invention is not limited to this and can also be located on the other side of the airbag. The gas interface is configured for gas input and gas discharge. The gas interface 21 is connected to the air pump. Each airbag is provided with an inlet valve 4 and an exhaust valve 5. The inlet valve 4 and the exhaust valve 5 are connected to the gas interface 21 through a connecting hose. Each airbag is provided with a pressure sensor 6. The inlet valve 4, the exhaust valve 5 and the pressure sensor 6 are connected to the power interface 22 through a cable. The controller 3 is electrically connected to the air pump, the inlet valve 4, the exhaust valve 5 and the pressure sensor 6.
[0034] This invention comprises 30 airbags, including 28 strip-shaped airbags and 2 square airbags, 30 electric air intake valves and 30 electric air exhaust valves, totaling 60 electric and pneumatic valves, and 30 pipelines connected to the airbags. Each airbag can independently and automatically intake and exhaust air, achieving individual controllability of each airbag.
[0035] Each airbag is equipped with an independent pressure sensor 6, and the controller 3 collects air pressure data. The touch screen 31 of the controller 3 displays the air pressure data obtained from the pressure sensor 6 in real time, thereby monitoring the status of each airbag in real time. Then, the controller can control the air pump to individually inflate or deflate each airbag as needed.
[0036] The body position modes of the intelligently controlled multifunctional medical air cushion of the present invention include: (1) supine position, in which the upper surfaces of the horizontal airbag area 11 and the lifting airbag area 12 are aligned by adjusting each airbag. (2) back-lifting position, in which the upper surface of the lifting airbag area 12 is higher than the upper surface of the horizontal airbag area 11 by adjusting each airbag. Figure 5As shown, raising the backrest achieves back support, providing a lift angle of no more than 45°. This lifts the head, shoulders, and heart relative to the lower body, while keeping the lower body roughly aligned with the horizontal plane. (3) Lateral tilt position: By controlling the two square airbags in the lateral tilt airbag area 13, such as... Figure 6 As shown, it enables the body to tilt to the left or right by pushing the back, and the two side-tilting square airbags can provide a side-tilting angle of no more than 25°.
[0037] The intelligent control multifunctional medical air cushion of the present invention can be set to a static mode, in which all airbags are inflated.
[0038] The intelligently controlled multifunctional medical air cushion of this invention can also be set with dynamic modes. These dynamic modes include a dynamic alternation mode for supine and back-lifted positions, where odd-numbered and even-numbered airbags in the horizontal and lifting airbag areas are alternately inflated and deflated in groups. The dynamic modes also include a dynamic alternation mode for lateral tilting positions, where the left airbag in the lateral tilting airbag area is alternately inflated and deflated to achieve cyclic left tilting; the right airbag in the lateral tilting airbag area is alternately inflated and deflated to achieve cyclic right tilting; and the left and right airbags in the lateral tilting airbag area are alternately inflated and deflated to achieve cyclic left and right lateral tilting.
[0039] It is understood that the lateral tilting function of the present invention has three modes: left lateral tilt, right lateral tilt, and alternating left and right lateral tilt.
[0040] The dynamic alternation time in the dynamic alternation mode can be set to any time and can be adjusted as needed.
[0041] The invention also has a timing function, for example, it can maintain a selected mode for 4 hours, 8 hours, 12 hours, etc.
[0042] The intelligent control multifunctional medical air cushion of the present invention is a precise comprehensive postural therapy and nursing device with a wide range of applications. It is not only suitable for treating and nursing various complications caused by long-term bed rest, realizing intelligent nursing and preventing pressure injuries, but also for daily care and treatment. Utilizing physiological and dynamic principles, an air pump is used to inflate and deflate the air cushion to achieve the required static or dynamic postural mode, thereby achieving the effects of daily care and treatment.
[0043] The electric intake valve and electric exhaust valve of the present invention can be 12V high-flow single-unit air valves.
[0044] The air pump of this invention can be a 220VAC high-flow electromagnetic pump with a specification of 50L / M. The air pump uses AC 220V, 50Hz power supply and has an IP21 protection rating.
[0045] The power supply of this invention uses a finished power module with 3C certification, 220VAC input, and 12V output. Because multiple air valves operate simultaneously, the power module has a power rating of over 60W.
[0046] In one embodiment of the present invention, such as Figure 1 As shown, the controller may include a touch screen display 31, an emergency button 32, and a buzzer alarm light 33. The touch screen display 31 shows the current pressure of each airbag, the operating status of the air pump, the upper and lower limits of the required airbag pressure, the operation of each inlet and outlet valve, and various operating modes, including alternating odd and even airbag settings, a warning for prolonged constant air pressure, left and right tilting control, and airbag pressure modes. In the event of an emergency, pressing the emergency button 32 will stop the airbag in its current state, immediately stop the air pump, or cause all airbags to deflate. When parameters exceed the set standard values, the buzzer alarm light 33 will sound an alarm. Figure 1 The controller 3 shown in the image has ventilation and heat dissipation functions on both sides, and handles are installed on both sides for easy movement of the control cabinet.
[0047] In the intelligently controlled multifunctional medical airbag according to the present invention, each airbag may be equipped with a manual deflation valve 7, which is disposed on the outer cover 2. The manual deflation valve 7 is preferably disposed on the side end of the outer cover 2. Each airbag is provided with a one-handedly operable manual deflation valve 7, which may have two positions: deflation and pressure holding. The manual deflation and pressure holding functions are achieved by adjusting the knob at different positions, allowing the operator to easily adjust the airbag status in emergency or special circumstances.
[0048] Each airbag in this invention can be independently controlled for air intake and exhaust. Caregivers can depressurize or maintain pressure on specific airbags through the control interface of the controller 3 or the manual depressurization valve 7, achieving static and dynamic alternating modes for different body positions. This effectively prevents complications caused by prolonged bed rest, such as pressure injuries.
[0049] In the intelligent control multifunctional medical air cushion according to the present invention, flexible sensors (not shown) are provided on the horizontal airbag area 11 and the lifting airbag area 12, and are electrically connected to the controller. The flexible sensors can be attached to any position on the upper surface of the airbags (the surface in contact with the patient's body) in the horizontal airbag area 11 and the lifting airbag area 12 as needed. Preferably, flexible sensors are provided on areas prone to pressure injury (i.e., areas subjected to high force), such as the scapula, sacrum, coccyx, and heels. More preferably, the upper surface of the airbags in the horizontal and lifting airbag areas is completely covered with flexible sensors. The present invention uses flexible sensors to monitor vital signs data in real time, including information such as pressure, temperature, and humidity, and transmits the monitored data to the controller. The controller processes the monitored vital signs data and compares it with standard thresholds, generating an alarm signal when a predetermined threshold is reached. This alerts medical staff or the patient to adjust the patient's position promptly based on the monitored signal, effectively preventing pressure injury. Ultimately, this achieves the beneficial effects of reducing the difficulty of treatment and nursing care, reducing human resource consumption, and improving the accuracy and effectiveness of treatment and nursing care.
[0050] Reference Figure 7 When the user is in a supine position, the following areas are prone to pressure injuries and require the installation of flexible sensors: 1. Sacrococcygeal region – the largest bony prominence in the human body, bearing direct pressure from body weight when supine, and susceptible to friction and shear forces from the bed sheet (e.g., when the head of the bed is raised). 2. Heel – the calcaneus is only covered by a thin layer of soft tissue, making it prone to ischemia and necrosis from prolonged contact with the bed surface. 3. Occipital region (back of the head) – the weight of the head is concentrated on the occipital protuberance, especially in comatose patients or those using a neck brace. 4. Scapula – the inferior angle of the scapula may be compressed in emaciated patients. 5. Olecranon process of the elbow joint – prone to compression when the upper limb is improperly positioned or when the elbow is flexed.
[0051] Reference Figure 8 When the user is in a lateral decubitus position (i.e., the user is in a side-lying posture), the following areas are prone to pressure injuries and require the installation of flexible sensors: 1. Greater trochanter (lateral femoral protuberance) - When lying on the side, the pelvis and greater trochanter are in direct contact with the bed surface, resulting in concentrated pressure. 2. Auricle - When the head is in a side-lying position, the auricle is subjected to prolonged pressure and is easily overlooked. 3. Lateral ribs - In emaciated patients, the lower edge of the ribs lacks fat cushioning, making them prone to pressure sores. 4. Medial and lateral knee joints - When the legs are crossed, the medial condyle and lateral malleolus are easily subjected to pressure. 5. Acromion (lateral shoulder joint) - The weight of the upper limb is concentrated at the acromion, especially when combined with contractures or muscle atrophy.
[0052] Reference Figure 9When the user is in a prone position, the following areas are prone to pressure injuries and require the installation of flexible sensors: 1. Anterior superior iliac spine - a bony prominence at the front of the pelvis, directly compressed when prone. 2. Sternum / costal arch - the chest contacts the bed surface; thin patients or those with chest deformities are at higher risk. 3. Knee (patella) - the patella rubs against the bed surface when the knee is flexed, easily leading to shear force injuries. 4. Dorsum of the foot / toes - the skin on the dorsum of the foot is thin; the toes may be compressed or curled when prone.
[0053] When users are in a sitting or semi-reclining position, the following areas are prone to pressure injuries and require the installation of flexible sensors: 1. Ischial tuberosity – 80% of body weight is concentrated in the ischial tuberosity when sitting, making it the most common site for pressure sores. 2. Inferior angle of the scapula – When backrest support is inadequate, the scapula rubs against the backrest. 3. Spinal spinous processes – Spinal spinous processes are easily compressed in thin patients. 4. Heel – When the lower limb is hanging down, the heel contacts the footrest, making it prone to ischemia.
[0054] In addition, flexible sensors need to be installed on vulnerable areas of special high-risk groups: 1. Areas in contact with medical devices such as nasogastric tubes (nasal ala), endotracheal tubes (lips, behind the ears), oxygen tubes (behind the ears), urinary catheters (urethral opening), non-invasive masks (forehead, sides of the nose, bridge of the nose), neck collars (neck), tracheostomies (neck), restraint devices (limb joints), and monitoring instruments (back). 2. Patients with edema or hypoproteinemia – their skin is fragile all over, and bony prominences are more easily damaged. 3. Patients with spinal cord injuries – paraplegic patients have sensory loss, and the sacrum, coccyx, and ischial tuberosities are at extremely high risk.
[0055] In one embodiment, the controller of the present invention can be wirelessly connected to a remote smart device, which is a monitor and / or a mobile device of medical personnel and / or a smartphone of the patient or their relatives or caregivers. The controller can achieve real-time data visualization through wired or wireless transmission. The wireless connection includes one of Bluetooth, radio frequency, RFID, APP applet, Wi-Fi, and radar signals.
[0056] The intelligent control multifunctional medical air cushion according to the present invention may further include a remote control, which is communicatively connected to the controller. The remote control enables intelligent remote control; elderly individuals capable of independent operation can operate the remote control as needed to raise or lower their back or turn over. It can also perform timed turning, dynamic cyclic turning, etc., providing more professional care. The remote control settings are suitable for different groups of people with varying needs, such as those with decreased physical strength, bedridden elderly individuals, or postoperative patients, allowing for independent operation to adjust body position promptly and prevent pressure injuries or bedsores.
[0057] This invention can accurately reflect pressure values and intelligently adjust pressure distribution. It can be used as a special medical mattress for preventing pressure injuries. Its pressure alternation therapy mainly adjusts each airbag by pre-setting a pressure cycle mode, and fully considers the specific pressure value that the patient can bear and the individual differences of the patient.
[0058] The intelligently controlled multifunctional medical air cushion of this invention has a length ≥1000mm, a width ≥650mm, and a thickness ≥100mm, and can be applied to commonly used home single beds or hospital beds. In one embodiment, the length ≥2085mm, the width ≥800mm, and the thickness (at the edge) ≥215mm are suitable for international standard conventional hospital beds.
[0059] The intelligently controlled multifunctional medical air mattress of the present invention can be movably installed on a bed frame. The intelligently controlled multifunctional medical air mattress of the present invention can be installed on a hospital bed or sleeping bed as needed, and can be removed when not in use. It is simple and convenient to operate, lightweight, and easy to move, and is suitable for geriatric departments, health care departments, and nursing homes.
[0060] The outer cover 2 of this invention is a detachable cover. The detachable cover 2 facilitates cleaning and can be fixed in place by a concealed zipper located at the bottom of the air cushion to prevent accidental liquid contamination. The cover may be equipped with a fixing device, such as straps, to further improve connection stability and prevent patient displacement. The cover can be made of waterproof, easy-to-clean, and flame-retardant materials.
[0061] The airbag of this invention is made of high-quality polyurethane (PU) material, but PVC, silicone, rubber, thermoplastic elastomers, and other elastomer materials can also be used. The safe load-bearing capacity is ≥250kg. The airbag of this invention requires a high level of airtightness, capable of maintaining pressure for 12 hours in the event of a power outage.
[0062] The power cord of this invention is fixed to the side of the air cushion cover to avoid affecting patients and caregivers, while not affecting the operation of the air cushion and bed frame.
[0063] The preferred embodiments of the present invention have been described in detail above, but it should be understood that, if necessary, aspects of the embodiments can be modified to utilize aspects, features, and concepts from various patents, applications, and publications to provide other embodiments.
[0064] In light of the detailed description above, these and other changes can be made to the embodiments.
