[0017] First, see Figure 1 , Figure 1 Schematic diagram of the axial structure of the bed according to some embodiments of the bed device disclosed in the present invention. Figure 1 As shown, the above-mentioned bed device may include: a bed 1, a fixed shaft 2, a transmission component 3 and a pushing component 4, wherein: The transmission assembly 3 and the pushing assembly 4 are cross-laid in the bed frame of the bed body 1. The transmission assembly 3 may include a plurality of transmission devices 31 (for example, Figure 1The above-mentioned pushing assembly 4 may include a plurality of pushing devices 41 (for example, Figure 1 There is a gap between the adjacent transmission devices 31 and the pushing devices 41. Here, the gap is used to avoid power conflict between the adjacent transmission devices 31 and the pushing devices 41. In practice, the gap can be set to a smaller value to avoid pinching of the user.
[0018] A fixed shaft 5 is respectively arranged in the middle of the bed frame of the bed body 1, so as to fix each transmission device 31 in the transmission assembly 3 through the fixed shaft 5. Each transmission device 31 is correspondingly provided with a rotating motor to drive the transmission device 31 to transmit to the left or right. Here, each rotating motor can be separately controlled by the corresponding rotating motor.
[0019] As an example, Figure 2 As shown, Figure 2 The rotating motor 32 corresponding to the transmission device 31 is shown in FIG.
[0020] Each pushing device 41 in the pushing assembly 4 and each transmission device 31 in the transmission assembly 3 are arranged at the same height of the top surface to serve as the manned bed surface of the bed body.
[0021] As an example, Figure 3 As shown, Figure 3 The schematic diagram of the bed structure of the bed device from above is shown. Here, the manned bed surface is paved by the upper surfaces of the driving devices 41 and the transmission devices 31. In practice, the upper surfaces of the driving devices 41 and the transmission devices 31 can also be fixed with flexible mattresses to ensure the comfort of the patient lying on the manned bed surface.
[0022] Optionally, each pushing device 41 may include two hydraulic telescopic rods 411, a device fixing frame 412 and a pushing plate 413, wherein: The device fixing frame 412 is provided with two parallel cross bars. Screw holes are provided on both sides of the device fixing frame 412 for being fixedly connected to the bed body 1 by screws.
[0023] As an example, Figure 4 As shown in the front view of the bed structure, two parallel cross bars are arranged below the side of each pushing device 41.
[0024] It is used to connect the bases of the two hydraulic telescopic rods 411 with the two parallel crossbar rotating shafts. The two hydraulics are arranged obliquely outwards along the direction of the telescopic rods 411 parallel to the crossbars.

Here, a protrusion is provided on the connecting plate to facilitate loading the pushing device 41 onto the bed frame. At the same time, by setting the connecting plate to load onto the bed frame, it is also possible to avoid conflict with the fixed shaft 5 of the rotating device 31.
[0029] As an example, see also Figure 7 Schematic diagram of the side structure of the pushing device.
[0030] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the bed device of some embodiments of the present disclosure, accurate posture adjustment can be provided to the patient in time. Specifically, the reason why it is difficult to provide patients with meticulous and accurate nursing care in time is that the nursing staff manually adjusts the patient's posture in bed according to experience, and places some items on the bed to fix the patient's posture. Based on this, the bed device of some embodiments of the present disclosure includes: a bed, a fixed shaft, a transmission assembly and a pushing assembly, wherein: the above-mentioned transmission assembly and the above-mentioned pushing assembly are cross-laid in the bed frame of the above-mentioned bed, wherein the above-mentioned transmission assembly includes a plurality of transmission devices, and the above-mentioned pushing assembly includes a plurality of pushing devices, and there is a gap between the adjacently laid transmission devices and pushing devices. Here, by cross-laying the transmission device and the pushing device, the adjustment power can be provided in the form of a combination of two auxiliary powers in the process of posture adjustment for the patient. Then, the middle of the bed frame of the above-mentioned bed is respectively provided with a fixed shaft body, which is used to fix each transmission device in the above-mentioned transmission assembly through the fixed shaft body, wherein each transmission device is correspondingly provided with a rotating motor to drive the transmission device to drive to the left or right. Thus, it is possible to drive different parts of the patient to exert force in coordination and adjust the patient's posture, thereby achieving the purpose of a suitable posture. Finally, each pushing device in the pushing assembly and each transmission device in the transmission assembly are set at the same height of the top surface to serve as the manned bed surface of the bed body. Thus, a comfortable bed surface design can be provided for the patient. At the same time, accurate posture adjustment can also be provided for the patient. Thus, meticulous and accurate care can be provided for the patient. See below Figure 8 , Figure 8 A flowchart 800 of some embodiments of a device control method for assisting a comatose patient in adjusting body position according to the present disclosure is shown. The device control method for assisting a comatose patient in adjusting body position comprises the following steps: Step 801, obtaining patient vital sign data collected by a vital sign detection device.
[0031] In some embodiments, the execution subject of the device control method for assisting the comatose patient in adjusting the body position (for example, the terminal controlling the camera calibration) can obtain the patient's vital sign data collected by the vital sign detection device. Among them, the above-mentioned vital sign detection device may include but is not limited to at least one of the following: a heart rate sensor, a blood pressure sensor, a blood oxygen saturation sensor, a joint temperature sensor, and a joint pressure sensor. The above-mentioned patient's vital sign data may include but is not limited to at least one of the following: heart rate data, blood pressure data, blood oxygen saturation data, a patient's joint temperature value group, and a patient's joint pressure value group. Here, the joint temperature sensor may be provided with multiple sensing ends to collect the patient's joint temperature values at different joints of the patient. For example, the patient's joint parts may include but are not limited to at least one of the following: elbows, knees, wrists, shoulders, ankles and other joint parts. In addition, the joint pressure sensor may also be provided with multiple sensing ends to collect the joint pressure values of different joints of the patient.
[0032] Step 802: Perform data analysis on the patient's vital sign data to generate a vital sign data analysis result.
[0033] In some embodiments, the execution subject may perform data analysis on the patient's vital sign data to generate a vital sign data analysis result. Here, the data analysis may be to analyze whether there are abnormal conditions in the patient's vital sign data. For example, the abnormal conditions may be: high blood pressure, high heart rate, high joint pressure value, etc.
[0034] Optionally, the execution subject performs data analysis on the patient's vital sign data to generate a vital sign data analysis result, which may include the following steps: In the first step, in response to determining that the heart rate data in the patient's vital sign data exceeds a preset heart rate range, or the blood pressure data exceeds a preset blood pressure range, or the blood oxygen saturation data exceeds a preset blood oxygen range, a vital sign data analysis result of monitoring abnormality is generated. For each data item, if it exceeds the corresponding numerical range, a corresponding abnormality mark can be generated.
[0035] In the second step, for the patient joint pressure value group in the patient's vital sign data that exceeds the preset pressure threshold, determine the duration of exceeding the preset pressure threshold. The continuous duration of exceeding the preset pressure threshold up to the current moment can be obtained as the duration of exceeding the preset pressure threshold.
[0036] The third step is to generate abnormal monitoring vital sign data analysis results in response to determining that the above duration is greater than the preset duration and that there is a patient joint temperature value that exceeds the preset temperature range in the above patient joint temperature value group. Among them, the above duration is greater than the preset duration, which can indicate that there is abnormal pressure in some joints of the patient and posture adjustment is required. Secondly, the vital sign data analysis results may include but are not limited to at least one of the following: an indicator indicating abnormal patient joint temperature and an indicator indicating abnormal patient joint pressure.
[0037] In practice, corresponding joint marks may be pre-set for different joints of the patient for differentiation. Thus, the mark of abnormal joint temperature and the mark of abnormal joint pressure of the patient may be marked with the corresponding joint.
[0038] Step 803 : in response to determining that the vital sign data analysis result is abnormal, performing a device control operation on the bed device according to a preset bed device control mode.
[0039] In some embodiments, the execution subject may, in response to determining that the above-mentioned vital sign data analysis result is abnormal, perform a device control operation on the above-mentioned bed device according to a preset bed device control mode. The above-mentioned device control operation may include but is not limited to at least one of the following: controlling each transmission device in the above-mentioned bed device to transmit to the left or right, and controlling each pushing device in the above-mentioned bed device to perform a pushing operation. Different parts of the patient correspond to different transmission devices or pushing devices on the above-mentioned bed device.
[0040] Here, when the patient is on the bed device, the head can be on the first transmission device at either end, the back can be on the adjacent pushing device, and the waist can be on the middle transmission device.
[0041] In practice, long-term bed rest in coma can cause various physical harms, such as pressure sores, aspiration pneumonia, venous thrombosis, urinary tract infection, joint contracture, etc. Since the patients themselves are unable to feedback their physical condition to medical staff, they need to rely entirely on nursing staff to provide effective care based on various monitoring indicators.
[0042] Optionally, in response to determining that the vital sign data analysis result is abnormal, the execution subject performs a device control operation on the bed according to a preset bed device control mode, including: The first step is to determine whether the posture duration of the bed device reaches the target duration in response to determining that the preset bed device control mode is the manual control mode. The manual control mode can be a mode for prompting medical staff to manually control the bed to adjust the patient's position when the patient is in an abnormal condition.
[0043] In the second step, in response to determining that the posture duration reaches the target duration, or obtaining a vital sign data analysis result representing a monitoring abnormality, a patient abnormality warning is sent to the bound nursing terminal.
[0044] In practice, medical staff can pre-set routine time period nursing control parameters according to individual differences and treatment requirements of patients. For example, set the time interval for turning over (such as once every 2 hours). When the preset time is reached, the device emits a loud audio or obvious visual prompt (such as flashing lights) to remind the nursing staff to turn over. However, when the above-mentioned bed is used to adjust the patient's position, the following technical problem 2 still exists: if the transmission is only performed by the transmission device as a whole, it is difficult to adjust the patient's posture. For example, it is difficult for the patient to adjust his posture when lying flat. If it is only pushed by the pushing device, it is easy to cause more serious harm to the patient. For example, when the patient is lying on his side, direct pushing is likely to cause the patient to fall to the side due to gravity. At the same time, it is difficult to coordinate control, and more operations are required, resulting in a waste of power resources.
[0045] As an example, an early warning is triggered when the patient's vital signs data exceeds the normal range by a certain degree, such as a heart rate that is too fast or too slow (exceeding the normal heart rate range ±[X] times / minute), blood pressure that is too high or too low (systolic blood pressure is higher than [specific value] mmHg or lower than [specific value] mmHg, diastolic blood pressure is higher than [specific value] mmHg or lower than [specific value] mmHg), blood oxygen saturation is lower than [specific value]%, etc.
[0046] As another example, when the temperature of a compressed part of the body rises abnormally (such as exceeding the normal skin temperature [X]℃), it indicates that there may be local inflammation or tissue damage; an abnormal decrease in temperature (such as lower than the normal skin temperature [X]℃) may indicate blood flow obstruction. When the pressure sensor detects that the local pressure is continuously too high (exceeding the safety pressure threshold [specific value] mmHg) and lasts for more than [set duration], an early warning is also triggered. In addition, the early warning information can be transmitted to the caregiver in a variety of ways, including the device's own sound and light alarm, and a pop-up early warning notification on the nurse station or the mobile terminal carried by the caregiver (such as a mobile phone APP), displaying the patient's bed number, name, abnormal physical signs information, and possible cause analysis, so that the caregiver can respond in time and take appropriate care measures.
[0047] Optionally, in response to determining that the vital sign data analysis result is abnormal, the execution subject performs a device control operation on the bed according to a preset bed device control mode, and may further include the following steps: In the first step, in response to determining that the preset bed device control mode is the automatic control mode, the patient posture adjustment information is determined according to the generated vital sign data analysis result representing the abnormal monitoring. The patient posture adjustment information may include a target body orientation indicator. The automatic control mode may be a mode in which the bed device is controlled to automatically adjust the patient posture according to the patient data.
[0048] In practice, the patient's posture can be pre-set to multiple directions. For example, the patient's posture direction may include: left, upper left, upward, upper right, right. In addition, each direction may correspond to a direction mark. Thus, the direction mark of the patient's current direction can be determined as the target body direction mark.
[0049] In the second step, according to the patient posture adjustment information, the device control operation is performed on the bed through the following steps: Step 1: Obtain the patient's body length data and the patient's current body orientation indicator. The patient's body circumference data may include but is not limited to at least one of the following: a head circumference value, a waist circumference value, and a leg length value.
[0050] Step 2: Using the head circumference value, waist circumference value and leg length value included in the patient's body circumference data, establish bed equipment control data that adjusts the patient's orientation state represented by the patient's current body orientation mark to the patient's orientation state represented by the target body orientation mark in the patient's posture adjustment information. The bed equipment control data may include control data corresponding to each transmission device and push device in the bed equipment: the transmission direction and transmission distance of the transmission device at the patient's head position, the transmission direction and transmission distance of the transmission device at the patient's waist position, the transmission direction and transmission distance of the transmission device at the patient's feet position, the pushing height of the pushing device at the patient's back, the pushing height of the pushing device at the patient's thigh position, and device operation timing information.
[0051] Specifically, first, the moving length between different parts of the patient from the patient orientation state represented by the patient's current body orientation mark to the patient orientation state represented by the target body orientation mark in the patient posture adjustment information can be determined. For example, the patient orientation state represented by the patient's current body orientation mark is leftward (i.e., lying on the left side). The patient orientation state represented by the target body orientation mark in the patient posture adjustment information is upward (i.e., lying flat). Then, the patient's head can be transformed from the leftward state to the upward state, so the moving length of the head can be one-fourth of the head circumference value, as the transmission distance of the transmission device corresponding to the patient's head. The transmission direction of the transmission device is to move in the opposite direction of the transformation from the leftward state to the upward state using the gear effect, so as to achieve the purpose of adjusting the orientation posture for the patient. Similarly, the transmission direction and transmission distance of the transmission device at the patient's waist position, and the transmission distance and transmission direction of the transmission device at the patient's foot position can be determined. Here, considering that when the human body changes from the side-lying state to the flat-lying state, the body will drive the legs and feet to rotate, so it is not necessary to transmit the transmission device of the feet and legs. When the human body is adjusted from the flat-lying state to the side-lying state, the legs do not move, and there is an uncoordinated and uncomfortable situation. Therefore, the transmission device where the foot is located is driven toward the patient's side-lying direction, so that the patient's legs are extended in the direction, so as to achieve the purpose of coordinated and comfortable posture, and further reduce local pressure.
[0052] Then, the pushing height of the pushing device at the patient's back and the pushing height of the pushing device at the patient's thigh can be determined. Here, considering the above-mentioned technical problem 2, when the patient adjusts his posture, the two pushing devices can be mobilized according to the patient's orientation state represented by the patient's current body orientation mark, and pushed upward from two directions to support the patient, so as to slow down the trend of the patient's posture change and achieve the purpose of avoiding secondary injury to the patient.
[0053] For example, if the patient's current body orientation indicator indicates that the patient's orientation is to the left (i.e., lying on the left side), then the push device on the patient's back can be used as the main support plate, lifted up from the patient's direction (for example, the lifting angle can be 20 degrees). Then the push device on the patient's thigh is lifted up from the patient's orientation direction, providing the patient with a natural force for changing from lying on the left side to lying flat.
[0054] Finally, determine the device operation timing information. Here, the above-mentioned operations can be adjusted as a whole according to the order of the actual body posture change of the patient. For example, first lift the pushing device (e.g., 10 degrees) at the patient's thigh position and the pushing device (e.g., 20 degrees) at the patient's back, and control the corresponding transmission device to transmit in the opposite (or same) direction of the patient's posture change according to each transmission direction and transmission distance, so as to utilize inertia to cooperate with the gravity of the pushing device (e.g., 10 degrees) at the patient's thigh position, so that the patient's posture changes from left to upward state. Then, the pushing device at the patient's thigh position can be gradually raised, and the pushing device at the patient's back can be gradually lowered, so as to assist the patient to slowly change posture. Thus, on the basis of avoiding secondary injury to the patient, the purpose of automatically changing the patient's posture is achieved. Therefore, the operation sequence and corresponding operation distance of each transmission device and pushing device can be recorded as the device operation timing information.
[0055] Step 3: According to the device operation timing information, each transmission device and pushing device is sequentially controlled to perform rotation operation and pushing operation, so as to adjust the patient from the state corresponding to the patient's current body orientation mark to the patient's orientation state represented by the target body orientation mark. The transmission distance, transmission direction, and pushing height in the device operation timing information can be converted into signals for controlling the transmission device and pushing device, so as to sequentially control each transmission device and pushing device to perform rotation operation and pushing operation.
[0056] For example, the transmission time of the transmission device is controlled to control the transmission distance according to the transmission speed. The pushing time of the pushing device is controlled to control the corresponding pushing angle.
[0057] Optionally, the execution subject determines the patient posture adjustment information according to the generated vital sign data analysis result representing the monitoring abnormality, which may include the following steps: The first step is to obtain the adjustment direction closing mark preset by the user for the current patient. Here, the adjustment direction closing mark can be a patient posture orientation indicating that adjustment is prohibited.
[0058] In practice, if there are certain parts of the patient's body that cannot be compressed, the medical staff can pre-set the corresponding patient posture orientation that is prohibited from adjustment.
[0059] In the second step, the user rotation direction mark corresponding to the adjustment direction closing mark in the preset user rotation direction mark group is removed to obtain a patient rotation direction mark group after removal.
[0060] The third step is to record the duration of each body orientation corresponding to each removed patient rotation direction identifier in the removed patient rotation direction identifier group of the current patient, and sort the removed patient rotation direction identifiers according to the generated vital sign data analysis results representing the monitoring abnormalities and each duration to obtain a patient rotation direction identifier sequence.
[0061] In practice, in the automatic control mode, considering that the patient is in the same posture for a long time and there is abnormal compression, it is necessary not only to adjust the patient's posture according to the preset duration or abnormal situation, but also to consider the duration of the patient's previous posture. Therefore, the priority of the patient's posture adjustment can be sorted out by sorting. Thus, it can be avoided that the posture is still unsuitable after adjustment or is unsuitable in the short term. In addition, the operation of the bed device is greatly reduced, thereby further reducing power consumption.
[0062] The fourth step is to select the first patient rotation direction identifier from each patient rotation direction identifier in the above-mentioned patient rotation direction identifier sequence except the identifier corresponding to the above-mentioned patient's current body orientation as the target body orientation identifier, and determine the above-mentioned target body orientation identifier as the patient posture adjustment information.
[0063] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the device control method for assisting the comatose patient to adjust the body position of some embodiments of the present disclosure, the above-mentioned technical problem 2 is solved, and accurate posture adjustment can be provided for the patient, and the power consumption of the bed device can also be reduced. Specifically: First, by dividing the device control into two modes, manual and automatic, it can be used to deal with different actual scenarios. Then, considering that different joint parts of the patient can be pre-set with corresponding joint marks for distinction. Thus, the mark of abnormal joint temperature of the patient and the mark of abnormal joint pressure of the patient can be marked with corresponding joint parts. Considering that it is difficult for the patient to adjust his posture in a lying state. If it is pushed only by the pushing device, it is easy to cause more serious harm to the patient. For example, when the patient is lying on his side, direct pushing is easy to cause the patient to fall to the side due to gravity. At the same time, it is difficult to coordinate control, and more operations are required, thereby resulting in a waste of power resources. Therefore, first of all, considering that when the human body changes from a lying state to a lying state, the body will drive the legs and feet to rotate, so it is not necessary to transmit the transmission device of the feet and legs. When the human body is adjusted from a lying state to a side-lying state, the legs do not move, and there is an uncoordinated and uncomfortable situation. Therefore, the transmission device where the foot is located is transmitted to the patient's side-lying direction, so that the patient's legs extend in the direction, so as to achieve the purpose of comfortable coordination of the patient's own posture, and further reduce local pressure. Then, considering the above-mentioned technical problem 2, when the patient adjusts his posture, the two pushing devices can be mobilized according to the patient's current body orientation state represented by the patient's current body orientation mark, and the patient can be pushed upward from two directions to support the patient, so as to slow down the trend of the patient's posture change and achieve the purpose of avoiding secondary injury to the patient. Afterwards, the above-mentioned operations are adjusted as a whole according to the order of the patient's actual body posture change. For example, the pushing device at the patient's thigh position (e.g., 10 degrees) and the pushing device at the patient's back (e.g., 20 degrees) are first lifted, and at the same time, the corresponding transmission device is controlled according to each transmission direction and transmission distance to transmit in the opposite (or same) direction of the patient's posture change, so as to use inertia to cooperate with the gravity of the pushing device at the patient's thigh position (e.g., 10 degrees) to change the patient's posture from left to upward. Then, the pushing device at the patient's thigh position can be gradually raised, and the pushing device at the patient's back can be gradually lowered, so as to assist the patient to slowly change posture. Thus, the purpose of automatically changing the patient's posture is achieved on the basis of avoiding secondary injury to the patient. Thus, the purpose of collaboratively controlling the transmission device and the pushing device according to the actual needs of the patient is achieved. Finally, considering that the patient is in the same posture for a long time and there is abnormal compression, it is necessary not only to adjust the patient's posture according to the preset duration or abnormal situation, but also to consider the duration of the patient's previous posture. Therefore, the priority of the patient's posture adjustment can be sorted out.Thus, it is possible to avoid the situation where the posture is still unsuitable after adjustment or is unsuitable in the short term. Furthermore, the operation of the bed device is greatly reduced, thereby further reducing power consumption. The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
