Abstract
Description
Technical Field
[0001] Embodiments of the present disclosure relate to a prone position support device, and more particularly to a prone position support device and a method for controlling the prone position support device. Background Art
[0002] During treatment, intubated patients with severe lung conditions often need to lie prone to increase blood oxygen levels and accelerate recovery. In the ward, patients are required to lie on a standard bed in a prone, head-on position, typically for approximately 10 hours. This prolonged prone position can cause pressure sores or numbness on the face and ears due to pressure, and nursing staff must adjust the head position every 2-3 hours. These frequent adjustments increase the risk of tube dislodgement or misplacement. Furthermore, because the patient is intubated and has various treatment tubes inserted, any movement carries the risk of tube dislocation. The depth of the endotracheal tube varies from patient to patient, and intubation that is too deep or too shallow can affect the treatment outcome. Furthermore, because the tube is inserted into the patient's mouth and nose, the patient will naturally secrete fluids due to physiological reactions. This fluid can make the tube slippery and the securing tape loose, potentially causing it to dislodge or become misplaced.

[0008] In a second aspect, some embodiments of the present disclosure provide a method for controlling a prone support device for a prone support device such as the first aspect described above, for assisting a patient in adjusting their head posture, the method comprising: in response to receiving a monitoring start instruction, controlling a network camera in the prone support device to capture an image to obtain a warehouse image, and controlling a global camera to capture an entire image of the prone support device to obtain an entire image of the device; based on the warehouse image, generating a human head feature point coordinate group and an equipment pipeline feature point coordinate group, wherein the equipment pipeline detection is used to detect pipelines embedded in the prone support device; performing face orientation detection on the coordinates of each human head feature point in the human head feature point coordinate group to generate a face orientation vector; and performing face orientation detection on the equipment pipeline.

[0009] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the prone position support device of some embodiments of the present disclosure, the patient can be automatically provided with the head posture adjustment to avoid the risk of pressure sores, numbness, and tube detachment. Specifically, the reason for the risk of pressure sores, numbness, and tube detachment is that during the treatment of patients with severe lung disease and tracheal intubation, they often need to adopt a prone position to increase blood oxygen levels and speed up physical recovery. In the ward, the patient needs to lie on an ordinary bed in a prone side-head position, usually for about 10 hours. The prolonged prone position will cause pressure sores or numbness on the patient's face and ears due to pressure. The nursing staff needs to adjust the head position every 2-3 hours. Multiple adjustments also increase the risk of dislocation and malposition of the tube. In addition, since the patient is in an intubated state and has various treatment tubes inserted into his body, any movement carries the risk of the tubes coming out; the depth of the intubation is also strictly required for different patients, and being too deep or too shallow will affect the treatment effect of the patient, and since the tube is inserted into the patient's mouth and nose, the patient will naturally discharge secretions due to physiological reactions, and the secretions will make the tube slippery and the fixing tape loose, causing the tube to come out or become dislocated. Based on this, some embodiments of the prone position support device disclosed herein include: a hollow groove is provided at one end of the top surface of the above-mentioned bed structure. The other end of the top surface of the above-mentioned bed structure is tilted toward the end where the hollow groove is located, and the top surface of the above-mentioned bed structure serves as a bed to support the user's body. Here, the tilted setting can be used to avoid the patient's gastric reflux and secretions flowing out of the mouth and nose. Then, the above-mentioned head support compartment is horizontally arranged at the hollow groove of the above-mentioned bed structure. Among them, the above-mentioned head support bin is divided into two upper and lower bin bodies. The lower bin body of the above-mentioned head support bin is fixed on the above-mentioned support bin transmission device, which is used to provide head support for the user on the bed. One end of the upper bin body of the above-mentioned head support bin is connected to the above-mentioned lower bin body rotating shaft, and the other end is provided with a buckle, which is used to fit the upper and lower bin bodies in the working state. There are also multiple groups of grooves on both sides of the above-mentioned upper bin body for embedding transmission pipes of different models.

[0018] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".
[0019] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.
[0020] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0021] First, see Figure 1 , Figure 1 Schematic diagram of the axial structure of the bed body according to some embodiments of the prone position support device disclosed herein. Figure 1 As shown, the above-mentioned prone position support device includes: a bed structure 1, a circular head support chamber 2 and a support chamber transmission device 3, wherein:
[0022] One end of the top surface of the bed structure 1 is provided with a hollow groove 4. The other end of the top surface of the bed structure 1 is tilted toward the end where the hollow groove is located. The top surface of the bed structure serves as the bed body for supporting the user's body. Here, the tilt setting refers to setting the bed body in an inclined position.
[0023] In practice, the bed structure 1 is only schematic.
[0024] Here, as Figure 1 As shown, the legs of the bed structure can also be hydraulically extended, allowing the bed to be raised and lowered by a motor. This allows for manual or automatic adjustment of the height of one end or the entire bed, achieving a tilted position. This can also be used to prevent reflux of gastric fluid or secretions.
[0025] The head support bin 2 is laterally arranged at the hollow groove 4 of the bed structure 1. The head support bin 2 is divided into two upper and lower bins. The lower end bin 21 of the head support bin is fixed on the support bin transmission device 3, and is used to provide head support for the user on the bed structure 1. One end of the upper end bin 21 of the head support bin 2 is connected 221 to the rotating shaft of the lower end bin 22. A buckle 222 is provided at the other end for engaging the upper and lower bins in the working state. A plurality of grooves 211 are also provided on both sides of the upper end bin 21 for embedding transmission pipes of different models.
[0026] As an example, Figure 2 Before the patient lies down, the upper compartment 21 can be opened. After the patient lies down and the assistive device is assembled, the upper compartment 21 can be closed. Finally, the pipeline of the assistive device can be embedded in the groove 211 by medical staff.
[0027] In practice, a spring clamp may be provided in the groove to clamp the embedded transmission pipe. Alternatively, a fastening device may be provided at the opening of the groove to also clamp the embedded transmission pipe. This is not specifically limited here.
[0028] The head support compartment 2 is in transmission connection with the support compartment transmission device 3. When in operation, the support compartment transmission device 3 can provide power to the head support compartment 2 to rotate left or right, thereby driving the user's head on the bed structure 1 to rotate. The rotation angle of the head support compartment 2 can be within 60 degrees.
[0029] The supporting bin transmission device 3 is fixedly connected to the back side of the bed structure 1 .
[0030] Optionally, a network camera 212 is further installed on the top inner side of the upper end chamber body 21 of the head support chamber 2, and a breathable memory foam 223 is further provided on the bottom inner side of the lower end chamber body 22 of the head support chamber 2, wherein:
[0031] In the working state, the breathable memory foam 223 is used to receive the user's head. The user's head is equipped with an auxiliary device, and the pipeline of the auxiliary device is embedded in the groove 211 on the side of the upper storage body 21 for fixing the pipeline.
[0032] Here, as Figure 1 The middle portion of the lower cabin (including the breathable memory foam 223) is shown as being removable. When the user is in a supine position, the middle portion can be attached to provide head support. When the user is in a prone position, the removable middle portion can be removed to provide both head support and assistive devices.
[0033] As an example, the assistive device may include but is not limited to at least one of the following: an oxygen mask, an endotracheal tube, etc.
[0034] In the working state, the network camera 212 captures the image of the lower warehouse body 22 and sends the captured warehouse body image to the image processing device for storage.
[0035] As an example, you can Figure 3 As shown, the network camera 212 is located at the top inner side of the upper chamber body 21. In practice, the network camera can be a wireless camera or a wired camera. The wired camera circuit can be embedded in the left side of the head support chamber 2 and extend downward, and is connected to the motor 31 of the support chamber transmission device 3 at the same time. Figure 3 Also shown is a fixed gear assembly 32, which is located on the same gear track as the motor 31 of the transmission device 3, to support the head support chamber 2. Furthermore, given the relatively wide width of the head support chamber 2, if the outer side were entirely covered with gears, it would hinder medical care. If the driven gear were too narrow, stability would be compromised. Therefore, a slide rail with the same curvature as the driven gear is provided on the other side of the head support chamber 2 to support the head support chamber 2.
[0036] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the prone position support device of some embodiments of the present disclosure, the patient can be automatically provided with the head posture adjustment to avoid the risk of pressure sores, numbness, and tube detachment. Specifically, the reason for the risk of pressure sores, numbness, and tube detachment is that during the treatment of patients with severe lung disease and tracheal intubation, they often need to adopt a prone position to increase blood oxygen levels and speed up physical recovery. In the ward, the patient needs to lie on an ordinary bed in a prone side-head position, usually for about 10 hours. The prolonged prone position will cause pressure sores or numbness on the patient's face and ears due to pressure. The nursing staff needs to adjust the head position every 2-3 hours. Multiple adjustments also increase the risk of dislocation and malposition of the tube. In addition, since the patient is in an intubated state and has various treatment tubes inserted into his body, any movement carries the risk of the tubes coming out; the depth of the intubation is also strictly required for different patients, and being too deep or too shallow will affect the treatment effect of the patient, and since the tube is inserted into the patient's mouth and nose, the patient will naturally discharge secretions due to physiological reactions, and the secretions will make the tube slippery and the fixing tape loose, causing the tube to come out or become dislocated. Based on this, some embodiments of the prone position support device disclosed herein include: a hollow groove is provided at one end of the top surface of the above-mentioned bed structure. The other end of the top surface of the above-mentioned bed structure is tilted toward the end where the hollow groove is located, and the top surface of the above-mentioned bed structure serves as a bed to support the user's body. Here, the tilted setting can be used to avoid the patient's gastric reflux and secretions flowing out of the mouth and nose. Then, the above-mentioned head support compartment is horizontally arranged at the hollow groove of the above-mentioned bed structure. Among them, the above-mentioned head support bin is divided into two upper and lower bin bodies. The lower bin body of the above-mentioned head support bin is fixed on the above-mentioned support bin transmission device, which is used to provide head support for the user on the bed. One end of the upper bin body of the above-mentioned head support bin is connected to the above-mentioned lower bin body rotating shaft, and the other end is provided with a buckle, which is used to fit the upper and lower bin bodies in the working state. There are also multiple groups of grooves on both sides of the above-mentioned upper bin body for embedding transmission pipes of different models. Here, by setting the grooves, it can be used to fix the pipeline to prevent the pipeline from falling out or being dislocated. Finally, the above-mentioned head support bin is connected to the above-mentioned support bin transmission device in a transmission manner, wherein the support bin transmission device provides power to the above-mentioned head support bin in the working state to rotate left or right, so as to drive the head of the user on the bed to rotate. The above-mentioned support bin transmission device is fixedly connected to the back of the above-mentioned bed structure. Thereby, the head state of the patient can be adjusted in time to avoid the risks of pressure sores, numbness, and pipeline falling off.
[0037] See below Figure 4 , Figure 4A flowchart 400 is shown of some embodiments of a method for controlling a prone support device according to the present disclosure. The method for controlling a prone support device, which is also used to assist a patient in adjusting their head posture, includes the following steps:
[0038] Step 401, in response to receiving the monitoring start instruction, control the network camera in the prone position support device to capture images to obtain a warehouse image, and control the global camera to capture the entire image of the prone position support device to obtain an overall image of the device.
[0039] In practice, to monitor user status, multiple cameras are often deployed, along with anomaly detection and alarms. However, this often makes it difficult to detect more detailed information, such as changes in piping. Furthermore, the control of the prone support device is imprecise, leading to wasted power. Therefore, automated algorithms are needed for monitoring, early warning, and control.
[0040] In some embodiments, the subject executing the prone position support device control method may, in response to receiving a monitoring start command, control a network camera in the prone position support device to capture an image to obtain a chamber image, and control a global camera to capture an entire image of the prone position support device to obtain an overall image of the device. The global camera may be mounted on a wall near the prone position support device to capture an entire image of the prone position support device bed structure from a bird's-eye view.
[0041] Step 402: Generate a human head feature point coordinate group and an equipment pipeline feature point coordinate group based on the warehouse image.
[0042] In some embodiments, the execution subject may generate a set of human head feature point coordinates and a set of equipment pipeline feature point coordinates based on the chamber image. The equipment pipeline detection is used to detect pipelines embedded in the prone support device.
[0043] In some optional implementations of some embodiments, the execution subject generates a human head feature point coordinate group and a device pipeline feature point coordinate group based on the warehouse image, which may include the following steps:
[0044] The first step is to extract feature points from the warehouse image to generate a head feature point group and an equipment and pipeline feature point group. Feature point extraction can be performed on the warehouse image using a preset feature point extraction algorithm to generate the head feature point group and the equipment and pipeline feature point group.
[0045] As an example, the feature point extraction algorithm includes but is not limited to at least one of the following: SIFT (Scale-invariant Feature Transform) algorithm, Surf (Speeded Up Robust Features) algorithm, FAST corner detection, BRIEF (Binary Robust Independent Elementary Features, feature descriptor algorithm), etc.
[0046] The second step is to perform feature point processing on the head feature point group to obtain a set of human head feature point coordinates. The set of human head feature point coordinates may include, but is not limited to, coordinates of human head feature points from at least one of the following categories: eyes, nose, mouth, ears, and face. Feature point processing may also involve removing redundant feature point coordinates using an adaptive filtering algorithm.
[0047] As an example, the human head feature point coordinate group may include the human head feature point coordinates corresponding to the eyes, nose, mouth, ears, face, and other positions.
[0048] The third step is to perform feature point processing on the equipment and pipeline feature point group to obtain the equipment and pipeline feature point group. The equipment and pipeline feature point group can be obtained by performing coordinate filtering on the equipment and pipeline feature point group using the adaptive filtering algorithm.
[0049] Step 403 : performing face orientation detection on the coordinates of each human head feature point in the human head feature point coordinate group to generate a face orientation vector.
[0050] In some embodiments, the execution entity may perform face orientation detection on each of the human head feature point coordinates in the human head feature point coordinate group to generate a face orientation vector.
[0051] In some optional implementations of some embodiments, the execution subject performs face orientation detection on each human head feature point coordinate in the human head feature point coordinate group to generate a face orientation vector, which may include the following steps:
[0052] The first step is to project each of the human head feature point coordinates in the human head feature point coordinate set into the camera coordinate system of the network camera to obtain a projected head feature point coordinate set. The coordinates of each human head feature point can be projected from the image coordinate system into the camera coordinate system of the network camera using a coordinate conversion algorithm and a pre-set conversion matrix.
[0053] The second step is to determine the vector between two symmetrical projected head feature point coordinates in the projected head feature point coordinate group as a head feature vector, thereby obtaining a head feature vector group. The two symmetrical projected head feature point coordinates indicate a corresponding relationship on the head. Here, the two symmetrical projected head feature point coordinates can be determined by the ordinates of the projected head feature point coordinates.
[0054] The third step is to determine the dot product of two symmetrical head feature vectors in the above head feature vector group, and the modulus length of every two head feature vectors.
[0055] The fourth step is to determine the product of each dot product and the modulus as the cosine value of the angle, and use the inverse cosine function to generate the feature point angle.
[0056] In the fifth step, the average value of the angles of the feature points is determined as the target angle value, and based on the target angle value, a face orientation vector relative to the horizontal plane is generated in the camera coordinate system. The face orientation vector can be a unit vector.
[0057] Therefore, the face orientation can be identified through the coordinates of facial feature points, which can pave the way for subsequent facial posture adjustment. Here, considering that there are multiple faces in the same posture of the human body and they are not easy to identify, the face orientation recognition and the human posture recognition are separated to avoid recognition errors and data overlap. At the same time, because the face orientation can be accurately located, the head posture can be adjusted on this basis in the future. This avoids pressure sores caused by the head being in the same posture for a long time.
[0058] Step 404 : extract the pipeline structure of each device pipeline feature point coordinate in the device pipeline feature point coordinate group to generate a pipeline structure vector diagram.
[0059] In some embodiments, the execution entity may perform pipeline structure extraction on the coordinates of each device pipeline feature point in the device pipeline feature point coordinate group to generate a pipeline structure vector diagram.
[0060] In some optional implementations of some embodiments, the execution entity extracts the pipeline structure of each device pipeline feature point coordinate in the device pipeline feature point coordinate group to generate a pipeline structure vector map, which may include the following steps:
[0061] The first step is to project the coordinates of each equipment pipeline feature point in the above equipment pipeline feature point coordinate group into the above camera coordinate system to obtain a projected pipeline coordinate group.
[0062] The second step is to repeatedly group the projected pipeline coordinates within the projected pipeline coordinate group to generate a set of equipment pipeline group coordinate groups. Pipeline diameter parameters can be pre-set as the grouping basis. The projected pipeline coordinates corresponding to each pipeline are then assigned to the equipment pipeline group coordinate group based on the attributes of the feature points (such as position, direction, and size). Because pipeline ends often intersect, the coordinates at the ends can be repeatedly grouped.
[0063] The third step is to perform coordinate fitting on each device pipeline group coordinate group in the above device pipeline group coordinate group set to generate a pipeline structure curve equation, thereby obtaining a pipeline structure curve equation group, wherein each pipeline structure curve equation can represent a pipeline.
[0064] The fourth step is to perform structural sampling on each pipeline structure curve equation in the aforementioned pipeline structure curve equation group to obtain a pipeline structure sampling coordinate sequence. Structural sampling can be performed by extracting equidistant coordinates on the curve containing the pipeline structure curve equation as the pipeline structure sampling coordinate sequence. The sampling coordinate range can be the maximum range of the coordinates of each device pipeline feature point in the device pipeline feature point coordinate group.
[0065] Step 5: Use the individual pipeline structure sampling coordinates in the pipeline structure sampling coordinate sequence to construct a pipeline structure vector diagram in the camera coordinate system. Each pipeline structure sampling coordinate in each pipeline structure sampling coordinate sequence can be plotted in a graphics coordinate system, and then the coordinates are connected in sequence. Finally, an interpolation algorithm is used to smooth the lines. The graphics coordinate system can be the camera coordinate system.
[0066] In practice, even if the pipeline is fixed, it will still move due to gravity when the equipment rotates. Therefore, by generating a pipeline structure vector diagram, it can be used to compare pipeline movement errors in real time. This can provide timely warning of pipeline displacement.
[0067] Step 405 , detecting the humidity information of each pipeline through a pipeline external humidity detector to obtain a pipeline humidity information group, and obtaining the liquid flow rate information of each pipeline through a pipeline liquid flow rate detector to obtain a pipeline liquid flow rate information group.
[0068] In some embodiments, the above-mentioned execution entity can detect the humidity information of each pipeline through a pipeline external humidity detector to obtain a pipeline humidity information group, and obtain the liquid flow rate information of each pipeline through a pipeline liquid flow rate detector to obtain a pipeline liquid flow rate information group.
[0069] In practice, external humidity detectors and internal liquid flow rate detectors can be used to accurately monitor external humidity. By setting specific flow rate thresholds and liquid outflow time thresholds, if the flow rate of external secretions from the tube increases or the outflow time exceeds the specified number of minutes, an immediate warning signal will be issued, prompting medical staff to promptly check the patient's tube condition so that they can quickly rush to the patient's bedside to make adjustments.
[0070] Step 406: Based on the overall image of the device and the face orientation vector, the head support compartment in the prone position support device is controlled to rotate left or right according to a preset human head rotation table to assist the patient in adjusting the head posture.
[0071] In some embodiments, the above-mentioned execution entity can control the head support compartment in the above-mentioned prone position support device to rotate left or right based on the overall image of the above-mentioned device and the above-mentioned face orientation vector according to a preset human head rotation table to assist the patient in adjusting the head posture.
[0072] In some optional implementations of some embodiments, the execution subject controls the head support chamber in the prone position support device to rotate left or right based on the overall image of the device and the face orientation vector according to a preset human head rotation table to assist the patient in adjusting the head posture, which may include the following steps:
[0073] The first step is to perform human body detection on the entire device image to generate a human body posture identifier. The human body posture identifier represents a human body in at least one of the following states: lying on the left side, lying on the right side, and lying flat. Here, human body detection can be performed on the entire device image using a preset human body detection algorithm to generate the human body posture identifier.
[0074] As an example, the human detection algorithm may include but is not limited to at least one of the following: a MoveNet lightweight human pose estimation model, an OpenPose real-time multi-person two-dimensional pose estimation model.
[0075] In the second step, according to the above-mentioned human posture identifier, a head rotation angle value that matches the above-mentioned face orientation vector is selected from the above-mentioned human head rotation table. Among them, the above-mentioned head rotation angle value is the next angle to be adjusted corresponding to the above-mentioned face orientation vector. Here, the human head rotation table may include pre-set human posture identifiers and corresponding rotatable angles and other parameters. Therefore, the next matching head rotation angle value can be selected according to the human posture identifier. For example, the human posture identifier represents a lying state of the human body, then the rotatable angle can be within a range of fifty degrees on both sides based on the center point of the human head to the top. In addition, the distance between the angles to be adjusted can be 10 degrees or 20 degrees, etc.
[0076] The third step is to generate a control signal using the above-mentioned head rotation angle value. First, the rotation direction identifier corresponding to the head rotation angle value can be determined. For example, a left rotation identifier or a right rotation identifier. Secondly, a control signal is generated based on the rotation direction identifier and the head rotation angle value. Here, the control signal may include the electrode direction and startup duration of the motor in the support bin transmission device. In this way, it can be used to drive the head support bin in the support bin transmission device to adjust the angle and direction according to the control signal.
[0077] The fourth step is to send the above control signal to the support chamber transmission device of the above prone position support equipment to control the above head support chamber to rotate to the above head rotation angle to complete the patient's head posture adjustment.
[0078] In practice, considering that the angles and orientations of head rotation vary in different postures, a human head rotation table is introduced to provide regular parameters for controlling the prone support device. This allows the patient to quickly determine the direction of adjustment and adjust the posture.
[0079] Optionally, the execution subject may further include the following steps before controlling the warning device to issue an emergency warning in response to detecting that the pipeline liquid flow rate information group or the pipeline humidity information group contains pipeline liquid flow rate information or pipeline humidity information that meets the preset warning condition, or that the pipeline structure vector diagram does not meet the preset structure condition:
[0080] The first step is to determine whether the pipeline liquid flow rate information is less than a preset flow rate threshold. If the flow rate threshold is exceeded, the pipeline liquid flow rate information is determined to meet the preset warning condition; if the flow rate threshold is not exceeded, the pipeline liquid flow rate information is determined to not meet the preset warning condition.
[0081] The second step is to determine whether the pipeline humidity information exceeds a preset humidity threshold. If the humidity exceeds the threshold, it is determined that the pipeline humidity information meets the preset warning condition; if the humidity does not exceed the threshold, it is determined that the pipeline humidity information does not meet the preset warning condition.
[0082] The third step is to determine the pipeline structure vector diagram of the first stable frame as the structure reference vector diagram after receiving the monitoring start instruction. The construction method of the structure reference vector diagram can refer to the above step 404 and will not be described in detail.
[0083] In step 4, in response to determining that the pipeline structure vector diagram does not correspond to the first stable frame, a structural error value between the pipeline structure vector diagram and the structural reference vector diagram is determined. The structural error value between the pipeline structure vector diagram and the structural reference vector diagram can be determined using a least-squares algorithm or a distance algorithm.
[0084] In a fifth step, in response to determining that the structural error value is greater than a preset error threshold, it is determined that the pipeline structure vector diagram does not meet a preset structural condition.
[0085] Step 407: In response to detecting that the pipeline liquid flow rate information group or the pipeline humidity information group contains pipeline liquid flow rate information or pipeline humidity information that meets the preset warning conditions, or the pipeline structure vector diagram does not meet the preset structure conditions, the warning device is controlled to issue an emergency warning.
[0086] In some embodiments, the above-mentioned execution entity can control the warning device to issue an emergency warning in response to detecting that the pipeline liquid flow rate information group or the pipeline humidity information group contains pipeline liquid flow rate information or pipeline humidity information that meets the preset warning conditions, or the above-mentioned pipeline structure vector diagram does not meet the preset structural conditions.
[0087] The above-described embodiments of the present disclosure have the following beneficial effects: The prone support device control methods of some embodiments of the present disclosure further address the aforementioned technical issues, provide accurate posture adjustment for patients, and reduce power consumption for the prone support device. Specifically, by introducing a network camera and a global camera to capture images of the patient's head and the entire device, they can monitor the patient's head orientation and body orientation, respectively, avoiding recognition errors caused by simultaneous recognition. Secondly, by detecting pipeline humidity and flow rate, timely warnings can be provided to prevent unexpected situations, such as pipeline blockages. Furthermore, a face orientation vector is generated, and a head rotation table is pre-set based on the need to adjust the patient's head posture. This provides regular parameters for controlling the prone support device. The user's overall body orientation can also be used to determine the range within which the user can turn their head, allowing for precise and comfortable posture adjustment. Furthermore, to further monitor pipeline changes and prevent abnormalities caused by prone support device rotation, a pipeline structure vector diagram is constructed and compared between previous and subsequent frames to determine whether there are subtle changes in pipeline movement. This allows for more accurate pipeline monitoring. Furthermore, because the prone position support device secures the tubing, it ensures that the user's head remains relatively stationary relative to the tubing, further minimizing any undesirable movement. This eliminates the need for repeated manual adjustments due to tubing anomalies, thus reducing power consumption to a certain extent.
[0088] The above descriptions are merely some preferred embodiments of the present disclosure and illustrate the underlying technical principles. Those skilled in the art should understand that the scope of the invention encompassed by the embodiments of the present disclosure is not limited to technical solutions formed by specific combinations of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the aforementioned inventive concept. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
