Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a prone head support airbag cushion. Background Technology

[0002] In the medical field, the prone position is commonly used in surgical procedures, intensive care (such as prone ventilation for patients with acute respiratory distress syndrome), and rehabilitation therapy. When maintaining the prone position for an extended period, the patient's forehead and chin need to be effectively supported to maintain airway patency and reduce facial pressure injury.

[0003] For example, Chinese patent CN107913146A discloses a head support frame for prone positioning. Each wall of the support frame has ventilation holes and wall holes. The fixing device includes a connecting strap, a fixing ring, and a pillow fixing strap to secure a U-shaped pillow, preventing obstruction of the patient's mouth and nose when prone. However, because the fixing hole positions and connecting strap structure can only adapt to the position of the U-shaped pillow, the support strength and contact area are fixed, and cannot be dynamically adjusted according to changes in the contour of the patient's forehead and chin or changes in pressure distribution caused by prolonged prone positioning. This easily leads to concentrated local pressure, and prolonged pressure can cause skin ischemia and hypoxia, increasing the risk of pressure ulcers. Especially for obese, thin, or sensitive patients, the fixed support surface is unable to distribute the weight of the head, making the problem of obstructed local blood circulation even more prominent. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a prone head support airbag cushion in view of the above-mentioned defects of the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A prone head support airbag cushion is constructed, comprising a base with a plurality of sub-airbags arranged at intervals to form a forehead support airbag group and a chin support airbag group, respectively used to conform to the forehead and chin areas of the patient when prone; each sub-airbag is provided with a monitoring component for sensing the internal air pressure and surface temperature of the sub-airbag; it also includes a control module and an inflation / deflation component, each sub-airbag being connected to the inflation / deflation component, and both the inflation / deflation component and the monitoring component being electrically connected to the control module; the control module is used to inflate or deflate the sub-airbags according to the monitoring results of the monitoring component; wherein, during inflation / deflation, adjacent sub-airbags in the forehead support airbag group and adjacent sub-airbags in the chin support airbag group do not deflate simultaneously.

[0007] As an improvement to the prone head support airbag, the monitoring component includes a pressure sensor and a temperature sensor. Each sub-airbag has a contact surface that conforms to the patient's skin. The pressure sensor and the temperature sensor are both disposed on the inner wall of the sub-airbag, and the temperature sensor is positioned corresponding to the contact surface.

[0008] As an improvement to the prone head support airbag, the inflation / deflation assembly includes a pump and an air duct. The air duct has a main pipeline connected to the pump and several branch pipelines connected to the sub-airbags. Each branch pipeline is equipped with a solenoid valve.

[0009] As an improvement to the prone head support airbag cushion, the sub-airbags within the forehead support airbag group are arranged in an arc shape.

[0010] As an improvement to the prone head support airbag cushion, the sub-airbags within the chin support airbag group are arranged in a U-shape.

[0011] As an improvement to the prone head support airbag cushion, the sub-airbags in the forehead support airbag group and the chin support airbag group are distributed in at least two rows.

[0012] As an improvement to the prone head support airbag cushion, each of the sub-airbags is provided with a flexible connecting strap, and adjacent sub-airbags are hinged together by the flexible connecting strap.

[0013] As an improvement to the prone head support airbag cushion, it also includes an observation component. A receiving space for exposing the face is formed between the forehead support airbag group and the chin support airbag group. The observation component is disposed within the receiving space to assist in observing the condition of the patient's face.

[0014] As an improvement to the prone head support airbag cushion, the observation component includes a reflector located between the ends of the forehead support airbag assembly and the chin support airbag assembly, and the reflector is at least partially exposed outside the accommodating space.

[0015] As an improvement to the prone head support airbag, the observation component includes a camera located in the center of the accommodating space for capturing images of the patient's face; the camera is connected to a display located outside the accommodating space.

[0016] The beneficial effects of this invention are as follows: By real-time monitoring and adjustment of the internal air pressure and surface temperature of the sub-inflator, the sub-inflator can better conform to the patient's forehead and chin, maintaining appropriate support strength and temperature, and reducing the pressure and discomfort in the forehead and chin area when the patient is prone for a long time. Furthermore, restricting the simultaneous deflation of adjacent sub-inflators during inflation and deflation prevents support imbalance caused by sudden changes in local air pressure, ensuring that the patient's head always receives stable and reliable support during prone positioning, avoiding head shaking or displacement. Stable support and appropriate temperature reduce the risk of pressure sores and minimize potential harm to the patient caused by improper use of the sub-inflator, providing greater safety for patients during prone treatment or rest.

[0017] Furthermore, the spaced sub-airbags in the forehead and chin support airbag groups better adapt to the contours of the forehead and chin, providing close support, distributing pressure, reducing localized pressure concentration, and further lowering the likelihood of pressure ulcers. Simultaneously, the monitoring component is located on the sub-airbags and does not directly contact the patient's face, improving the patient's comfort when their face is in a prone position.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] A prone head support airbag cushion, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a base 1, on which several sub-airbags 2 are provided. The sub-airbags 2 are arranged at intervals to form a forehead support airbag group 21 and a chin support airbag group 22, which are used to fit the forehead and chin areas of the patient when lying prone, respectively. Each sub-airbag 2 is provided with a monitoring component 3 for sensing the internal air pressure and surface temperature of the sub-airbag 2. The device also includes a control module 4 and an inflation / deflation component 5. Each sub-airbag 2 is connected to the inflation / deflation component 5, and both the inflation / deflation component 5 and the monitoring component 3 are electrically connected to the control module 4. The control module 4 is used to inflate and deflate the sub-airbags 2 according to the monitoring results of the monitoring component 3. During the inflation / deflation process, adjacent sub-airbags 2 in the forehead support airbag group 21 and adjacent sub-airbags 2 in the chin support airbag group 22 do not deflate at the same time.

[0032] Specifically, prolonged prone positioning can easily lead to pressure sores on the forehead and chin where they contact the sub-inflator 2 due to poor local blood circulation. Monitoring surface temperature can promptly detect abnormal increases in local temperature caused by excessive pressure or prolonged contact time, often an early warning sign of pressure sores. Based on temperature data, healthcare professionals can use the control module 4 and inflation / deflation assembly 5 to adjust the air pressure of the corresponding sub-inflator 2, changing the pressure at the contact site, promoting blood circulation, and reducing the risk of pressure sores.

[0033] The sub-airbags 2 on the base 1 are divided into a forehead support airbag group 21 and a chin support airbag group 22. When the patient is prone, the two groups of sub-airbags 2 fit against the forehead and chin areas respectively. Monitoring components 3 installed on the sub-airbags 2 can sense the internal air pressure and surface temperature of the sub-airbags 2, generating corresponding monitoring data. All monitoring components 3 are electrically connected to the control module 4, transmitting the monitoring data to the control module 4. After receiving the data, the control module 4 analyzes and judges according to the set logic. When it is determined that the state of the sub-airbags 2 needs to be adjusted, the control module 4 sends a command to the inflation / deflation component 5. Since the sub-airbags 2 are all connected to the inflation / deflation component 5, the inflation / deflation component 5 inflates and deflates the sub-airbags 2 according to the command to adjust the air pressure of the sub-airbags 2 to a suitable range. During the inflation / deflation process, the forehead support airbag group 21 and the chin support airbag group 22 follow the rule that adjacent sub-airbags 2 do not deflate simultaneously. Because the sub-airbags 2 are arranged at intervals, and the adjacent sub-airbags 2 are relatively independent yet interconnected in structure, the setting that the adjacent sub-airbags 2 do not deflate at the same time can ensure that during the adjustment process, the support structure of the forehead and chin of the two sets of sub-airbags 2 will not experience sudden local pressure loss, thus maintaining the stability of the overall support.

[0034] By monitoring and adjusting the internal air pressure and surface temperature of the sub-inflator 2 in real time, it can better conform to the patient's forehead and chin, maintaining appropriate support strength and temperature, and reducing the pressure and discomfort in the forehead and chin area when the patient is prone for a long time. Limiting the simultaneous deflation of adjacent sub-inflators 2 during inflation and deflation prevents support imbalance caused by sudden changes in local air pressure. This ensures that the patient's head receives stable and reliable support throughout the prone position, preventing head movement or displacement. Stable support and appropriate temperature reduce the risk of pressure sores and minimize potential harm caused by improper use of the sub-inflator 2, providing greater safety for patients during prone treatment or rest. The sub-inflators 2 of the forehead support airbag group 21 and the chin support airbag group 22 are arranged alternately to better adapt to the contours of the forehead and chin, providing close support, distributing pressure, reducing local pressure concentration, and further reducing the likelihood of pressure sores. Furthermore, the monitoring component 3 is located on the sub-inflator 2 and does not directly contact the patient's face, improving the patient's facial comfort in the prone position.

[0035] Furthermore, the control module 4 is a microcontroller. The microcontroller models include, but are not limited to, Arduino Uno, STM32F103C8T6, and Raspberry Pi Zero W. It is responsible for analyzing and processing the data collected by the monitoring component 3, and issuing control commands to operate the inflation / deflation component 5 according to preset algorithms and logic.

[0036] In some embodiments of this application, such as Figure 3As shown, the monitoring component 3 includes a pressure sensor 31 and a temperature sensor 32. Each sub-airbag 2 has a contact surface that adheres to the patient's skin. Both the pressure sensor 31 and the temperature sensor 32 are located on the inner wall of the sub-airbag 2, with the temperature sensor 32 corresponding to the contact surface. Specifically, the pressure sensor 31 and temperature sensor 32 are installed on the inner wall of the sub-airbag 2. When the patient lies prone on the airbag pad, the sub-airbag 2 contacts the patient's skin. The pressure sensor 31 senses changes in the internal air pressure of the sub-airbag 2 and converts the pressure signal into an electrical signal. The air pressure change originates from the pressure exerted by the patient's head on the sub-airbag 2. The temperature sensor 32 is close to the contact surface that adheres to the skin, sensitively sensing temperature changes at the contact point between the patient's skin and the sub-airbag 2, converting these changes into an electrical signal, and transmitting it in real-time to the control module 4, providing data for subsequent inflation and deflation operations. To enhance comfort, pressure sensor 31 monitors the pressure of the sub-inflator 2, preventing excessive pressure that could cause patient discomfort. Temperature sensor 32 monitors the contact temperature, preventing abnormal temperatures from causing discomfort and ensuring patient comfort in the forehead and chin areas when using the air cushion. In preventing pressure ulcers, pressure sensor 31 monitors pressure distribution and adjusts the sub-inflator 2 pressure promptly to avoid excessive local pressure affecting blood circulation. Temperature sensor 32 monitors temperature and can detect abnormally high temperatures, often an early sign of pressure ulcers, allowing for timely adjustments and reducing the risk of pressure ulcers. Furthermore, temperature sensor 32 is located on the inner wall of the sub-inflator 2 and does not directly contact the patient's face, further improving the comfort of the patient's face when in contact with the sub-inflator 2.

[0037] Furthermore, the temperature sensor 32 can be configured as a digital temperature sensor 32, a linear temperature sensor 32, or a flexible temperature sensor 32 as required; the pressure sensor 31 can be configured as a silicon pressure sensor 31 or a thin-film pressure sensor 31 as required.

[0038] In some embodiments of this application, such as Figure 7As shown, the inflation / deflation assembly 5 includes a pump and an air guide pipe. The air guide pipe has a main pipe connected to the pump and several branch pipes connected to the sub-airbags 2. Each branch pipe is equipped with a solenoid valve. Specifically, based on the monitoring feedback from the monitoring assembly 3, the control module 4 determines when it needs to inflate or deflate one or more sub-airbags 2 and issues a corresponding command to the inflation / deflation assembly 5. The pump, acting as a power source, starts working. During inflation, the pump draws in outside air through the main pipe and then delivers it to the corresponding sub-airbag 2 along the branch pipes. The solenoid valves on the branch pipes act as on / off controls. The control module 4 individually controls the opening or closing of each solenoid valve according to specific needs, allowing the designated sub-airbag 2 to receive gas. During deflation, the pump reverses its operation to draw in gas. After the solenoid valves open, the gas inside the sub-airbag 2 is discharged through the branch pipes and the main pipe, achieving independent and precise adjustment of the air pressure in each sub-airbag 2. Because the solenoid valves of the branch lines can be controlled independently, each sub-airbag 2 can be individually inflated and deflated based on the data from the monitoring component 3. If a sub-airbag 2 detects insufficient pressure, it can be inflated alone without affecting the other sub-airbags 2. This allows the airbag cushions to provide a more snug and comfortable support for the patient's forehead and chin, effectively distributing pressure and reducing discomfort and the risk of pressure sores caused by localized pressure concentration. During patient use, if the monitoring component 3 detects that a sub-airbag 2 is too hot, it may be due to excessive pressure causing poor local blood circulation. In this case, the inflation / deflation component 5 can be used to deflate and depressurize the sub-airbag 2, adjusting its temperature without affecting the support effect of the other sub-airbags 2, ensuring patient comfort and safety.

[0039] Furthermore, the pump can be an oil-free silent air pump, a miniature diaphragm air pump, or a small piston air pump, depending on the requirements.

[0040] In some embodiments of this application, the sub-airbags 2 within the forehead support airbag assembly 21 are arranged in an arc shape. Specifically, the human forehead is not flat but has a certain curvature. The arc-shaped arrangement of the sub-airbags 2 within the forehead support airbag assembly 21 allows for better conformity to the natural contour of the forehead. When the patient lies prone, the sub-airbags 2 make even contact with various parts of the forehead, and each sub-airbag 2 effectively distributes the pressure on the head. The arc-shaped arrangement of the sub-airbags 2 closely conforms to the forehead curve, increasing the contact area with the forehead. Compared to other arrangements, the arc-shaped arrangement can more evenly distribute head pressure, reduce the risk of excessive local pressure, effectively reduce the probability of pressure sores, and improve patient comfort.

[0041] In some embodiments of this application, the sub-airbags 2 within the chin support airbag assembly 22 are arranged in a U-shape. Specifically, given the unique shape and contour of the human chin, the U-shaped arrangement of the sub-airbags 2 within the chin support airbag assembly 22 allows them to closely conform to the natural curve of the chin. When the patient lies prone, the U-shaped sub-airbags 2 provide comprehensive support from both sides and below the chin, evenly distributing the pressure on the chin. The U-shaped sub-airbags 2 closely fit the contour of the chin, increasing the contact area and ensuring that pressure is evenly distributed across all parts of the chin, effectively preventing localized pressure concentration.

[0042] In some embodiments of this application, the sub-airbags 2 within the forehead support airbag group 21 and the chin support airbag group 22 are distributed in at least two rows. Specifically, the sub-airbags 2 within the forehead support airbag group 21 and the chin support airbag group 22 are distributed in four rows. When the patient lies prone on the airbag pad, the weight of the head acts on the sub-airbags 2. The multi-row sub-airbag design increases the contact area with the forehead and chin, distributing pressure to more sub-airbags 2. Due to the different positions of the sub-airbags 2 in different rows, they can bear the pressure from different angles and layers. For example, the sub-airbags 2 near the center of the head mainly bear the vertical downward pressure, while the outer sub-airbags 2 can help disperse and buffer lateral pressure. During inflation and deflation, the sub-airbags 2 in different rows can be adjusted according to the data from the monitoring component 3. When the pressure in a certain area is too high, the corresponding row of sub-airbags 2 can be deflated, while the other rows of sub-airbags 2 maintain their current state, ensuring the stability of the overall support. In other embodiments, the number of rows of sub-airbags 2 in the forehead support airbag group 21 and the chin support airbag group 22 can be set to 2, 3, 5, 6, 7 or 8 rows as needed.

[0043] The multi-row sub-airbags 2 increase the contact area with the forehead and chin, more effectively distributing head pressure. This helps reduce localized pressure concentration, lowering the risk of pressure sores on the forehead and chin, and improving comfort. Different rows of sub-airbags 2 can work together to enhance overall support stability; even if the pressure on one row of sub-airbags 2 changes with slight head movement, other rows can promptly supplement support, preventing significant head swaying or displacement and ensuring patient safety during prone positioning. By selectively inflating and deflating different rows of sub-airbags 2, the support intensity for different areas of the head can be more precisely adjusted. For example, for patients with high foreheads, the air pressure of the front row of sub-airbags 2 can be increased; for patients with prominent chins, the lower sub-airbags 2 in the chin support airbag group 22 can be adjusted to meet the individual needs of different patients.

[0044] In some embodiments of this application, each sub-airbag 2 is provided with a flexible connecting strap 6, and adjacent sub-airbags 2 are hinged together by the flexible connecting strap 6. Specifically, the flexible connecting strap 6 is flexible, allowing relative movement between adjacent sub-airbags 2; it allows adjacent sub-airbags 2 to generate a linked tilt angle during inflation and deflation, thereby adapting in real time to the forehead and chin curves of different patients. Through the flexible hinge, the airbag group can form a continuous and gentle support surface, dynamically balancing the pressure distribution and significantly reducing the risk of pressure ulcers. For example, when a sub-airbag 2 needs to be deflated due to a patient's facial protrusion, adjacent sub-airbags 2 adjust their angle through the flexible linkage of the connecting strap to fill the gap and avoid local suspension or excessive pressure. At the same time, when the patient lies prone on the airbag pad and the head posture changes or moves slightly, the sub-airbags 2 can make corresponding adjustments through the hinge structure of the flexible connecting strap 6. For example, when the patient's head turns, the relative positions of each sub-airbag 2 can be changed through the movement of the flexible connecting strap 6 to adapt to the new head posture while maintaining their connection relationship. During inflation and deflation, the sub-airbag 2 will change shape and size due to changes in air pressure; the flexible connecting belt 6 can deform with the sub-airbag 2 as it expands or contracts, and will not restrict its normal inflation and deflation due to changes in the volume of the sub-airbag 2, ensuring that each sub-airbag 2 can work normally.

[0045] The flexible connecting strip 6 can be made of highly elastic and fatigue-resistant materials such as silicone or thermoplastic polyurethane, which can withstand repeated deformation without hindering the inflation and deflation function of the sub-airbag 2.

[0046] In some embodiments of this application, an observation component 8 is also included. A receiving space 7 for exposing the face is formed between the forehead support airbag group 21 and the chin support airbag group 22. The observation component 8 is disposed within the receiving space 7 to assist in observing the patient's facial condition. Specifically, the receiving space 7 between the forehead support airbag group 21 and the chin support airbag group 22 exposes the patient's face, and the observation component 8 is disposed within the receiving space 7. Medical personnel can observe the patient's complexion, expression, breathing, etc., through the observation component 8 to promptly detect abnormalities. For example, a pale complexion may indicate a health problem, and rapid breathing may indicate a respiratory system disorder. Medical personnel can observe these conditions at any time without frequently moving the patient's head, so as to make rapid diagnostic and treatment decisions and improve the timeliness and accuracy of medical care.

[0047] In some embodiments of this application, such as Figure 8As shown, the observation component 8 includes a reflector 81, which is located between the ends of the forehead support airbag assembly 21 and the chin support airbag assembly 22, and is at least partially exposed outside the receiving space 7. Specifically, the reflector 81 is mounted on the base 1. Utilizing the principle of light reflection, the reflector 81 is positioned between the ends of the forehead support airbag assembly 21 and the chin support airbag assembly 22, and is partially exposed outside the receiving space 7. When light shines on the patient's face, the light reflected from the face is projected onto the reflector 81. After reflection by the reflector 81, the image of the patient's face is reflected outside the receiving space 7, allowing medical personnel to observe the patient's facial condition from the outside through the reflector 81, including complexion, expression, and nasal movements during breathing, thereby obtaining information about the patient's physiological state.

[0048] When an air cushion is used on a patient in a prone position, medical staff can observe the patient's facial condition at any time through a reflective mirror 81 without disturbing the patient's prone position or affecting the treatment process. For example, during some long surgeries, medical staff can quickly observe the patient during breaks in the procedure, promptly detect any possible abnormalities, and save time and effort without needing to adjust the patient's head position.

[0049] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the observation component 8 includes a camera 82 located in the center of the accommodating space 7, used to capture the patient's facial features. The camera 82 is connected to a display 83 located outside the accommodating space 7. Specifically, both the camera 82 and the display 83 are mounted on the base 1. The camera 82, located in the center of the accommodating space 7, can directly capture the patient's face. The camera 82 transmits the optical image via a connection line to the display 83 located outside the accommodating space 7, where it displays a visual image, allowing medical staff to intuitively observe the patient's facial features. Through the camera 82 and the display 83, medical staff can clearly observe the patient's face from a distance, avoiding the risk of cross-infection from frequent close proximity to the patient's head. This is especially beneficial in environments with high hygiene requirements, such as operating rooms and intensive care units, ensuring the health of both patients and medical staff. In complex medical scenarios, medical staff may not be able to observe patients closely at all times. The camera 82 can operate 24 hours a day, continuously monitoring the patient's facial condition without missing any subtle changes. Once an abnormality is detected, such as a patient's expression of pain or abnormal breathing, medical staff can promptly identify and take measures, improving the timeliness and accuracy of medical care.

[0050] Furthermore, the camera 82 can be a high-definition miniature CMOS camera 82, a medical-grade USB camera 82, or an infrared night vision camera 82.

[0051] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
