As shown in
In this embodiment, the air pressure determination module 1 is communicatively connected to the electric mattress 2 and is configured to determine a body mass index according to a height and a weight of a target object, determine a target mattress air pressure according to the body mass index and send the target mattress air pressure to the electric mattress 2; the electric mattress 2 is communicatively connected to the visualization module 3 and is configured to receive the target mattress air pressure, perform inflation or deflation processing according to the target mattress air pressure, acquire a pressure value corresponding to each target position, and send the pressure value to the visualization module 3, where the each target position is a position where a corresponding pressure sensor in the electric mattress contacts the target object; and the visualization module 3 is configured to receive and visually display the pressure value, determine guidance information corresponding to the pressure value according to the pressure value and display the guidance information.
The air pressure determination module 1 is configured to determine the body mass index according to the height and the weight of the target object, determine the target mattress air pressure according to the body mass index and send the target mattress air pressure to the electric mattress 2.
In this embodiment, the target object may be a patient who is bedridden and has restricted movement. The body mass index may be a numerical value for measuring the degree of obesity of a human body. The target mattress air pressure may be an air pressure in an electric mattress that is adapted to the target object. The electric mattress 2 may be a mattress that can be charged or discharged through electric control to adjust the softness of the mattress.
In an embodiment, the air pressure determination module 1 may acquire the height and the weight of the target object and input the height and the weight into a calculation formula of the body mass index to determine the body mass index of the target object. Further, that the target mattress air pressure corresponding to the body mass index is determined may be that the target mattress air pressure is determined through a preset correspondence relationship or may also be that the target mattress air pressure is determined through a preset function relationship. Moreover, the target mattress air pressure may be sent to the electric mattress 2 so that the electric mattress 2 can be adjusted according to the target mattress air pressure.
It is to be noted that the body mass index (BMI), also known as a BMI index, is a commonly used international standard for measuring the degree of obesity and health of a human body. The calculation formula of the body mass index is that BMI=weight+height2. (Weight unit: kilogram (kg); and height unit: meter (m)).
Exemplarily, the height and the weight of the target object may be input in advance so that the body mass index can be calculated. For example, in a hospital, the height and the weight of the target object may be measured at the time of admission detection. For example, the height is 1.6 m, and the weight is 50 kg. According to the height, the weight and the calculation formula of the body mass index, it is calculated that the body mass index=50÷1.62=19.53. According to a correspondence relationship between the body mass index and a mattress air pressure, the target mattress air pressure may be determined as 5.50 kPa and sent to the electric mattress 2.
Exemplarily, since the body mass index of the target object is associated with the target mattress air pressure, the target mattress air pressure may be determined through a following formula:
P denotes the target mattress air pressure, air pressure unit is kilopascal (kPa), and BMI denotes the body mass index of the target object.
It is to be noted that the preceding formula for determining the target mattress air pressure is only a manner for determining the target mattress air pressure. In an actual application process, other manners may be used for determining the target mattress air pressure, or adjustments may also be made to the preceding formula.
The electric mattress 2 is configured to receive the target mattress air pressure, perform the inflation or deflation processing according to the target mattress air pressure and acquire the pressure value corresponding to the each target position according to the target mattress air pressure and send the pressure value to the visualization module 3.
In this embodiment, multiple pressure sensors for measuring the current pressure are installed in the electric mattress 2 and may be evenly distributed throughout the electric mattress 2. The each target position may be a position where the corresponding pressure sensor in the electric mattress 2 contacts the target object. The pressure value may be a numerical value measured by the corresponding pressure sensor at the each target position.
Exemplarily, the electric mattress 2 receives the target mattress air pressure sent by the air pressure determination module 1 and adjusts the current mattress air pressure through inflation or deflation according to the target mattress air pressure so that the current mattress air pressure can reach the target mattress air pressure. Further, the pressure value of the each target position is measured by the corresponding pressure sensor on the electric mattress and is sent to the visualization module 3 so that the pressure value can be visualized and analyzed through the visualization module 3.
The visualization module 3 is configured to receive and visually display the pressure value, determine the guidance information corresponding to the pressure value according to the pressure value and display the guidance information.
In this embodiment, the guidance information may be guidance information for guiding nursing personnel to perform an operation, such as a prompt for guiding a position change or a mode adjustment.
Optionally, the visualization module 3 may receive the pressure value sent by the electric mattress 2 and perform an analysis according to the pressure value to determine whether the pressure value meets a requirement of the target object. Moreover, the guidance information corresponding to the pressure value may be determined according to the pressure value and is displayed so that a caregiver can adjust the posture of the target object according to the guidance information to avoid bedsores.
In this embodiment, the air pressure determination module determines the body mass index according to the height and the weight of the target object, determines the target mattress air pressure according to the body mass index and sends the target mattress air pressure to the electric mattress, the electric mattress receives the target mattress air pressure, performs the inflation or deflation processing according to the target mattress air pressure and acquires the pressure value corresponding to the each target position according to the target mattress air pressure and sends the pressure value to the visualization module, and the visualization module receives and visually displays the pressure value, determines the guidance information corresponding to the pressure value according to the pressure value and displays the guidance information. This approach addresses issues such as the inability to monitor the electric mattress in real-time and the inability to provide suitable mattress air pressures for different users, enabling the provision of an electric mattress with a suitable air pressure for the target object, alleviating nursing workload, and preventing bedsores.
Referring to
Optionally, the air pressure determination module 1 is further configured to determine a mattress inflation air pressure or a mattress deflation air pressure according to the target mattress air pressure and send the mattress inflation air pressure or the mattress deflation air pressure to the electric mattress 2 according to a preset cycle; and the electric mattress 2 is further configured to receive the mattress inflation air pressure or the mattress deflation air pressure and perform the inflation or deflation processing according to the mattress inflation air pressure or the mattress deflation air pressure.
In this embodiment, the mattress inflation air pressure may have an air pressure value higher than the target mattress air pressure so that the electric mattress 2 can be inflated intermittently. The mattress deflation air pressure may have an air pressure value lower than the target mattress air pressure so that the electric mattress 2 can be deflated intermittently. The preset cycle may be an adjustment cycle during which the electric mattress 2 is controlled to inflate and deflate alternately.
Exemplarily, the air pressure determination module 1 may determine the mattress inflation air pressure or the mattress deflation air pressure according to the target mattress air pressure. For example, this may be that the mattress inflation air pressure=the target mattress air pressure×(1+5%) and that the mattress deflation air pressure=the target mattress air pressure×(1×5%). Specific numerical values may be adjusted according to actual cases. According to the preset cycle, the mattress inflation air pressure or the mattress deflation air pressure is sent to the electric mattress 2 so that the electric mattress 2 can fluctuate cyclically. When receiving the mattress inflation air pressure or the mattress deflation air pressure, the electric mattress 2 performs the inflation or deflation processing according to the mattress inflation air pressure or the mattress deflation air pressure so that the mattress air pressure of the electric mattress 2 can reach the required air pressure.
Exemplarily, according to the preset cycle, 0 to 20 min is determined for the target mattress air pressure, 20 to 40 min is determined for the mattress inflation air pressure, 40 to 60 min is determined for the target mattress air pressure, and 60 to 80 min is determined for the mattress deflation air pressure. A corresponding mattress air pressure value is sent to the electric mattress 2 at a corresponding moment so that the electric mattress 2 can fluctuate cyclically. Optionally, the visualization module 3 is configured to receive and visually display the pressure value and generate and display, in response to the pressure value reaching a guidance condition, guidance information corresponding to the guidance condition. The guidance condition may be a condition generated according to the pressure value and the duration of the pressure value and is configured to generate the guidance information. Exemplarily, the visualization module 3 receives and visually displays the pressure value so that the caregiver can intuitively understand the pressure value between the target object and the electric mattress 2. Moreover, when the pressure value meets the guidance condition, the current target object may be at the risk of pressure sores. At this time, the guidance information corresponding to the guidance condition may be displayed to remind the caregiver to perform corresponding operations. Optionally, the guidance information may include information such as adjusting the mode of the electric mattress or needing to adjust the position of the target object.
Exemplarily, when the pressure value exceeds 2.13 kPa (160 mmHg), the capillary perfusion to the tissue may be blocked. The pressure value above 4 to 4.6 kPa (30 to 35 mmHg) for 2 to 4 hours may cause pressure sores. Therefore, the guidance condition may be set as that the pressure value is greater than or equal to 4 kPa and that the duration reaches 1.5 hours. When the guidance condition is met, text reminder information is generated and displayed, such as “please adjust the working mode of the electric mattress to a fluctuation cycle mode” or “please help turn a patient over”. The guidance condition may also be set as that the pressure value is equal to 4 kPa and that the duration reaches 2 hours. When the guidance condition is met, the text reminder information is generated and displayed, and the guidance information may also be reminded strongly and sent to a terminal device of the caregiver such as a smartphone. This can enable the caregiver to acquire the guidance information and return to the bedside timely to perform corresponding operations when the caregiver is not by the bed.
Optionally, the air pressure determination module 1 is further configured to determine at least one to-be-adjusted airbag corresponding to each target moment within a fluctuation cycle mode and an airbag air pressure corresponding to each of the at least one to-be-adjusted airbag according to the target mattress air pressure, and send the airbag air pressures of the at least one to-be-adjusted airbag corresponding to the each target moment to the electric mattress 2 at the each target moment, where the electric mattress 2 includes at least two airbags; the electric mattress 2 is further configured to receive the airbag air pressures corresponding to the at least one to-be-adjusted airbag and inflate or deflate each to-be-adjusted airbag according to an airbag air pressure corresponding to the each to-be-adjusted airbag in the fluctuation cycle mode.
In this embodiment, the fluctuation cycle mode may be a mode in which different airbags in the electric mattress are controlled to inflate and deflate alternately, and the each target moment may be each moment within the fluctuation cycle mode. The at least one to-be-adjusted airbag may include multiple airbags involved in the fluctuation cycle mode. The airbag air pressure may be an air pressure that needs adjusting and corresponds to the each to-be-adjusted airbag.
Exemplarily, in the fluctuation cycle mode, the air pressure determination module 1 may determine airbags on which inflation or deflation adjustments are performed in a fluctuation cycle process and determine an airbag that corresponds to the each target moment and needs adjusting as the each to-be-adjusted airbag. In an embodiment, the airbag air pressure of the each to-be-adjusted airbag at the each target moment may be determined so that the electric mattress 2 can inflate or deflate different to-be-adjusted airbags to achieve a fluctuation cycle effect.
Exemplarily, multiple airbags on the electric mattress may be numbered. For example, 1 to 14 is numbered sequentially from the head to the feet of the target object. Airbags No. 1 and No. 2 correspond to the head and the neck of the target object and do not require inflation or deflation in the fluctuation cycle stage. Airbags No. 3 to No. 14 correspond to the torso parts of the target object and require inflation or deflation adjustments in the fluctuation cycle stage. In this case, the airbags No. 3 to No. 14 may serve as the to-be-adjusted airbags. In the fluctuation cycle mode, the multiple to-be-adjusted airbags are alternately inflated or deflated cyclically. For example, odd-numbered to-be-adjusted airbags (No. 3, No. 5, No. 7, No. 9, No. 11 and No. 13) are in the filled state, with an air pressure determined according to the target mattress air pressure, even-numbered to-be-adjusted airbags (No. 4, No. 6, No. 8, No. 10, No. 12 and No. 14) are in the deflated state, when an alternation cycle is reached, the even-numbered to-be-adjusted airbags are inflated to the filled state, with an airbag air pressure determined according to the target mattress air pressure, and the odd-numbered to-be-adjusted airbags are deflated.
It is to be noted that the preceding fluctuation cycle mode is an exemplary illustration.
The advantage of the preceding function lies in regularly reducing the patient's pressure through intermittent inflation and deflation. Due to sensory disturbance and decreased muscle tone, a hemiplegic patient needs to relax his limbs. The nursing workload is alleviated through the fluctuation cycle mode so that the hemiplegic patient can relax his body, lie down more comfortably and also alleviate the skin friction.
Optionally, as shown in
In this embodiment, the mode switching condition may be a condition for switching the working mode of the electric mattress 2, for example, the pressure value A lasts for 2 hours, or the posture of the target object is adjusted. Working modes may include modes such as dual tube fluctuation, sitting posture, nursing, static state and turning over.
Optionally, the mode adjustment module 7 receives the pressure value corresponding to the each target position and determines, according to the pressure value, whether the mode switching condition is reached and which mode switching condition is reached. Further, according to the mode switching condition, the working mode of the electric mattress 2 is switched and adjusted to save the caregiver's time of manual switching and also to avoid pressure sores caused by the caregiver's inability to adjust the working mode timely.
It is to be noted that the mode switching condition may be set according to the pressure value and the duration of the pressure value.

Optionally, the air pressure control unit 21 receives the target mattress air pressure sent by the air pressure determination module 1 and controls the inflator 22 according to the target mattress air pressure to inflate or deflate the at least two airbags 23 through the inflator 22. When the air pressures in the at least two airbags 23 meet the target mattress air pressure, the inflation or deflation is stopped, which may be caused by air leakage through the solenoid valve placed on the at least two airbags 23.
Optionally, to ensure the safety of the system and guarantee the safety of the target object, the system further includes a warning module 4.
The warning module 4 is connected to the electric mattress 2 and is configured to generate and send warning information in response to detecting a to-be-warned situation. The to-be-warned situation includes a situation where the electric mattress 2 is in a low-voltage state, a power-off state, or an unfilled state. The warning information may be information for prompting the fault of the electric mattress 2 and may be in the form of text or voice.
Optionally, the warning module 4 may detect the working status of the electric mattress 2. In the case where the warning module 3 detects that the electric mattress 2 is in the low-voltage state, the power-off state, or the unfilled state, the electric mattress 2 cannot work normally. At this time, the warning module 4 may generate and send the warning information so that the caregiver can troubleshoot and avoid adverse influences on the target object.
Exemplarily, when the warning module 4 detects that the electric mattress 2 is in the low-voltage state, the warning information may be sent to the terminal device of the caregiver, or the caregiver may also be reminded to pay attention in the form of voice broadcasting to repair the electric mattress 2 and to make the electric mattress 2 work normally.
Optionally, the comfort degree may also be reminded through the warning module 4. This may be that the warning module 4 is further configured to acquire the pressure value corresponding to the each target position in the electric mattress 2, determine the current pressure state according to the pressure value and a comfort pressure value and generate and send reminder information in response to the current pressure state being an uncomfortable state.
In this embodiment, the comfort pressure value may be a pressure value that is preset and conforms to the comfort degree of a human body.

The reminder information may be information for reminding the caregiver to manually adjust the current pressure state in response to the current pressure state not meeting the requirement and may be text information or voice information.
Optionally, the warning module 4 may acquire the pressure value corresponding to the each target position in the electric mattress 2 and determine the comfort degree of the target object through the pressure value. Further, the pressure value is compared with the comfort pressure value. In the case where the pressure value does not meet the requirement of the comfort pressure value, the air pressure of the electric mattress 2 cannot meet the requirement at this time, the current pressure state is determined to be an uncomfortable state, and the reminder information is generated and sent to remind the caregiver to adjust the air pressure of the electric mattress 2. In the case where the pressure value meets the requirement of the comfort pressure value, the air pressure of the electric mattress 2 can meet the requirement at this time, and the monitoring is continued.

The feedback mattress air pressure may have an air pressure value that needs adjusting for the current mattress air pressure.
Optionally, the pressure value corresponding to the each target position in the electric mattress 2 is acquired, and the comfort degree of the target object may be determined through the pressure value. Further, the pressure value is compared with the comfort pressure value, in the case where the pressure value does not meet the requirement of the comfort pressure value, the air pressure of the electric mattress 2 cannot meet the requirement at this time, the current pressure state is determined to be uncomfortable, and the mattress air pressure of the electric mattress 2 needs adjusting automatically. An adjustment manner may be that the feedback mattress air pressure is determined according to the pressure value and the comfort pressure value to inflate or deflate the electric mattress 2 through the feedback mattress air pressure. In the case where the pressure value meets the requirement of the comfort pressure value, the air pressure of the electric mattress 2 can meet the requirement at this time, adjustments are not required, and the monitoring is continued.
Optionally, to increase the determination accuracy of the target mattress air pressure, the anti-bedsore adjusting and monitoring system further includes an air pressure iteration module 6.

The skin pressure condition may include whether the skin is reddish due to pressure, or the current skin state. The subjective feeling may be the target object's subjective feeling of the softness of the mattress, such as satisfaction or dissatisfaction.
Optionally, at some regular times, a medical worker may evaluate the skin pressure condition of the target object and ask the target object about the subjective feeling of the softness of the mattress. According to the body mass index, the skin pressure condition and the subjective feeling, data is summarized and processed. The air pressure regression equation may be updated and constructed, and the updated air pressure regression equation is fed back to the air pressure determination module 1 so that the air pressure determination module 1 can determine a subsequent target mattress air pressure according to the updated air pressure regression equation.

Optionally, the anti-bedsore adjusting and monitoring system further includes a timing module 8 and a mode switching module 9.
The timing module 8 is connected to the mode switching module 9 and is configured to determine whether a working duration of the current working mode reaches a preset working duration corresponding to the current working mode, and generate and send a mode switching signal to the mode switching module based on a determination result that the working duration of the current working mode reaches the preset working duration corresponding to the current working mode; the mode switching module 9 is connected to the electric mattress 2 and is configured to switch a working mode of the electric mattress 2 based on a preset target working mode in response to receiving the mode switching signal.
In this embodiment, the current working mode may be a working mode that is currently being used by the electric mattress 2. The working duration may be a duration during which the current working mode is continuously used. The preset working duration may be the longest duration during which the current working mode may last. It is to be noted that the length of the preset working duration may be set separately according to different working modes. The mode switching signal may be a signal for triggering the switching of the working mode of the electric mattress 2. The target working mode may be a preset switchable working mode.
Optionally, the timing module 8 determines the current working mode of the electric mattress 2 and the working duration of the current working mode, determines whether the working duration of the current working mode reaches the preset working duration corresponding to the current working mode, continues timing and determining based on a determination result that the working duration of the current working mode does not reach the preset working duration corresponding to the current working mode, and generates and sends the mode switching signal to the mode switching module 9 based on the determination result that the working duration of the current working mode reaches the preset working duration corresponding to the current working mode. When receiving the mode switching signal, the mode switching module 9 determines a to-be-switched target working mode and switches the working mode of the electric mattress 2 to the target working mode.
Exemplarily, the current working mode is the static working mode, and the preset working duration corresponding to the static working mode is 10 min. When the timing module 8 determines that the working duration of the static working mode reaches 10 min, the mode switching signal is generated and sent to the mode switching module 9. When receiving the mode switching signal, the mode switching module 9 determines a to-be-switched target working mode as a turning-over working mode and controls the working mode of the electric mattress 2 to be switched to the turning-over working mode.
In this embodiment, the air pressure determination module determines the body mass index according to the height and the weight of the target object, determines the target mattress air pressure according to the body mass index and sends the target mattress air pressure to the electric mattress, the electric mattress receives the target mattress air pressure, performs the inflation or deflation processing according to the target mattress air pressure and acquires the pressure value corresponding to the each target position according to the target mattress air pressure and sends the pressure value to the visualization module, and the visualization module receives and visually displays the pressure value, determines the guidance information corresponding to the pressure value according to the pressure value and displays the guidance information. Moreover, the air pressure determination module determines the mattress inflation air pressure or the mattress deflation air pressure according to the target mattress air pressure and sends the mattress inflation air pressure or the mattress deflation air pressure to the electric mattress according to the preset cycle to automatically adjust the electric mattress. In this way, problems that the electric mattress cannot be monitored in real time and that regular muscle relaxation is required for users can be solved, the electric mattress with the suitable air pressure can be provided for the target object, the nursing workload required for muscle relaxation can be alleviated through cyclical inflation or deflation, and the bedsores can be avoided.
Optionally, the control box may be provided with an air pressure determination module and others and is configured to control the dual-tube fluctuation electric mattress to inflate or deflate.
Through the communication module, the working state of the mattress may be observed in real time and remotely controlled so that the workload of a caregiver can be reduced, and the patient comfort can be increased. Meanwhile, informationalized data can facilitate medical scientific research activities and increase the bedsore prevention efficiency.
The caregiver may control the mattress state and the fluctuation cycle time through the control box and make adjustments according to actual cases. From the perspective of the safety of a patient, when the mattress is in a low-voltage state, a power-off state, or an unfilled state, the system may issue a warning to remind the caregiver to make adjustments timely.
Height and weight adaptive technology may be used in the control box. Everyone has different heights and weights, and different body parameters determine that everyone has different needs for the optimal pressure provided by the mattress. Since an air bed may disperse the pressure on the body, increase the contact area with the mattress and reduce the pressure applied to the skin, pressure sores can be reduced. A suitable air bed pressure may effectively alleviate the local tissue pressure and increase the patient comfort, so a target mattress air pressure is determined according to body mass parameters. For example, the target mattress air pressure may be obtained according to the input height and weight information. It is to be noted that the target mattress air pressure is determined according to the height and weight of a target object. Each set of weight and height corresponds to a respective target mattress air pressure. Before an electric anti-bedsore mattress is used, the weight and height of the target object may be input in advance so that the setting of the target mattress air pressure can be completed.
The caregiver may perform visualization bedside pressure monitoring through the display and provide anti-bedsore risk guidance on the display. A display interface is shown in
Exemplarily, after the system is used for 2 h, 48 h, and 72 h, a supervising nurse may evaluate the skin pressure condition of the target object and ask the patient about the subjective feeling of the softness of the mattress. The skin pressure condition includes whether the skin is reddish due to pressure, and the patient's subjective feeling of the softness of the mattress includes satisfaction or dissatisfaction. Statistical software is used for data induction and processing, and a chi-squared test is used for data counting to conduct a linear correlation analysis between a body mass index and the mattress air pressure, and a linear regression analysis is used for constructing a regression equation to accurately determine the target mattress air pressure subsequently.
Moreover, the electric mattress helps the target object to regularly reduce the pressure through intermittent inflation and deflation. For example, due to sensory disturbance and decreased muscle tone, a hemiplegic patient has the nursing workload alleviated by an alternation fluctuation method so that the hemiplegic patient can relax his body parts, lie down more comfortably and alleviate the skin friction.
In the embodiment of the present application, the control box, the dual-tube fluctuation electric mattress, the communication module, the pressure sensor and the display construct the anti-bedsore adjusting and monitoring system. This solves problems in the related art that the use of the anti-bedsore mattress requires a nurse to spend a great deal of time on information statistics management, the working state of the mattress cannot be detected immediately, and the safety of the patient's bedsore prevention is relatively lacking so that the working state of the electric mattress can be monitored in real time and remotely controlled, an early warning feedback for an abnormal condition in the mattress can be sent immediately, the use safety can be improved, the adaptive pressure applicability can be provided for the patient, and the patient experience can be improved.
