Description

TECHNICAL FIELD

According to statistics, the population suffering from heart failure accounts for more than 1% of the total population, about 80 million heart failure patients of different degrees. Among them, 5% of the patients (about 4 million people) will develop severe heart failure. For patients with severe heart failure, the effect of drug treatment is not good, and the 5-year survival rate is only 20%, so heart transplantation has become the only most effective method for treating severe heart failure patients. Due to the limitation of donors and technology, the number of heart transplant recipients is less than 1% of the total number of patients who need transplantation, that is, the annual number of heart transplantation surgery worldwide is only 5000 cases. Because of the limited supply, a large number of heart disease patients die in despair while waiting for heart transplantation.

[0003] Heart donors are divided into two categories: ① human heart, ② artificial heart. Among them, human heart cannot meet the huge social demand due to extremely limited supply and serious rejection reaction, while artificial heart can overcome the problem of insufficient supply of transplant donors and also will not produce rejection reaction. Therefore, artificial heart will become the main hope and main force for treating severe heart failure patients.

[0057] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0058] Please refer to Figure 1 , Figure 1 is a flow chart of a control method of an artificial bionic heart provided by the embodiments of the present application, comprising the following steps:

[0059] Step 101, acquiring a body activity parameter, the activity parameter being used to represent a real-time situation of body activity of a user of the bionic heart;

[0060] It can be understood that the body activity parameter is acquired by a sensor, which continuously sends to the artificial bionic heart after sensing data. The sensor adopts a component with small volume and high sensitivity, and is arranged at a position of the body activity parameter of the user of the artificial bionic heart which needs to be monitored, for example, a position of sensing lung respiration, a position of sensing human body temperature or a position of sensing human body movement, etc.

[0061] In addition, if the volume of the sensor is large and cannot be arranged in the body, the sensor can be directly arranged at a position outside the body, preferably a portable clothes belt, etc. The sensor sends the monitored parameter to the artificial bionic heart in a wireless communication mode. The distance of the wireless communication is not less than a set distance, for example, the set distance is 10 m.

[0062] The artificial bionic heart can be a terminal or a chip with a transceiver, which can acquire the monitored parameter sent by the sensor and control the artificial bionic heart based on the body activity parameter.

[0063] Step 102, determining a target activity level according to the body activity parameter, the target activity level being used to represent the intensity of the current body activity situation.

[0064] It can be understood that the target activity level is one level in a plurality of preset activity levels, and the plurality of activity levels all represent intensity levels, and different levels correspond to different activity intensities. For example, the activity level includes four levels, which are level one, level two, level three and level four, and the activity intensity increases with the increase of the level. When the target activity intensity is level one, it represents the lowest activity intensity, and when the target activity intensity is level four, it represents the highest activity intensity. Of course, in the specific embodiments, the number of the activity levels is not limited, and the number of the levels can be set according to actual needs.

[0065] Step 103, multiplying or dividing the current speed of the artificial bionic heart by a preset adjustment coefficient according to the target activity level to obtain a target speed.

[0066] In the case of the target activity level being raised by one level, the product of the current beating speed of the artificial heart and the set coefficient is set as the first target speed; in the case of the target activity level being lowered by one level, the quotient of the current beating speed of the artificial heart and the set coefficient is set as the second target speed.

[0067] It can be understood that the beating speed of the artificial heart corresponding to different target activity levels is different. In the case of the target activity level being raised by one level, the activity intensity of the user is increased, and at this time, the beating speed of the artificial heart needs to be accelerated. In the embodiment, the product of the current beating speed of the artificial heart and the set coefficient is set as the first target speed, and the beating speed of the artificial heart is controlled to run at the first target speed to accelerate the beating speed of the artificial heart.

[0068] In the case of the target activity level being raised by one level, the current beating speed can also be added by a set speed value to obtain the first target speed, and the beating speed of the artificial heart is controlled to run at the first target speed to accelerate the beating speed of the artificial heart.

[0069] It can be understood that the first target speed is a speed greater than the current beating speed, and the first target speed corresponds to the target activity level. In the case of the target activity level being continuously raised by multiple levels, the first target speed is also determined by multiple times of calculation. For example, the target activity level is continuously raised by three levels, and the first target speed is determined by multiplying the current beating speed by the set coefficient three times.

[0070] In the case of the target activity level being raised by one level, the current beating speed can also be added by a set speed value to obtain the first target speed, and the beating speed of the artificial heart is controlled to run at the first target speed to accelerate the beating speed of the artificial heart.

[0071] In the case of the target activity level being continuously raised by multiple levels, the first target speed is also determined by multiple times of calculation. For example, the target activity level is continuously raised by three levels, and the first target speed is determined by adding the current beating speed by the set speed value three times.

[0072] It can be understood that the different target activity levels correspond to different beating speeds of the artificial heart. When the target activity level is lowered by one level, the activity intensity of the user is reduced, and the beating speed of the artificial heart needs to be slowed down. In the embodiment, the quotient of the current beating speed of the artificial heart and the set coefficient is set as the second target speed, and the beating speed of the artificial heart is controlled to run at the second target speed, so as to slow down the beating speed of the artificial heart.

[0073] In the embodiment, the current beating speed is subtracted by the set speed value to obtain the second target speed, and the beating speed of the artificial heart is controlled to run at the second target speed, so as to slow down the beating speed of the artificial heart.

[0074] It can be understood that the second target speed is a speed less than the current beating speed, and the second target speed corresponds to the target activity level. When the target activity level is continuously lowered by multiple levels, the second target speed is also determined multiple times. For example, when the target activity level is continuously lowered by two levels, the second target speed is determined by multiplying the current beating speed by the set coefficient twice.

[0075] In the embodiment, the current beating speed is subtracted by the set speed value to obtain the second target speed, and the beating speed of the artificial heart is controlled to run at the second target speed, so as to slow down the beating speed of the artificial heart.

[0076] In the embodiment, the current beating speed is subtracted by the set speed value to obtain the second target speed, and the beating speed of the artificial heart is controlled to run at the second target speed, so as to slow down the beating speed of the artificial heart.

[0077] It can be understood that each activity level corresponds to a beating speed, and the speed difference is the same when the target activity level is lowered to one level or raised to one level. For example, when the target activity level is raised from level one to level two, the beating speed changes from 20 to 30; when the target activity level is lowered from level two to level one, the beating speed changes from 30 to 20. The beating speed of level two is 1.5 times of the beating speed of level one, or the beating speed of level two is 10 different from the beating speed of level one.

[0078] Step 104, controlling the artificial bionic heart to run at the target speed.

[0079] In the embodiment of the present application, the monitoring parameter is acquired, the target activity level of the current activity is determined based on the monitoring parameter, and the beating speed of the artificial heart is adjusted according to the target activity level, so that the beating speed of the artificial heart is flexibly adjusted, and the flexibility of the adjustment is improved.

[0080] In one embodiment, the physical activity parameter includes at least one of a lung breath frequency parameter, a body temperature parameter, and a body movement intensity parameter.

[0081] The target activity level is determined according to the physical activity parameter, including:

[0082] The target activity level is determined according to at least one of the first activity parameter, the second activity parameter, and the third activity parameter.

[0083] The first activity parameter is an activity level determined in the first preset activity level according to the lung breath frequency parameter, the second activity parameter is an activity level determined in the second preset activity level according to the body temperature parameter, and the third activity parameter is an activity level determined in the third preset activity level according to the body movement intensity parameter.

[0084] Each preset activity level in the first preset activity level corresponds to a range of the lung breath frequency parameter, each preset activity level in the second preset activity level corresponds to a range of the body temperature parameter, and each preset activity level in the third preset activity level corresponds to a range of the body movement intensity parameter.

[0085] It can be understood that the first preset activity level set includes a plurality of preset activity levels, and the first preset activity level set is used to represent all levels corresponding to the lung breath frequency parameter. For example, the first preset activity set includes four levels, which are low level, medium level, high level, and high level. Among them, the range of breath frequency corresponding to the low level is 16-18 times / min, the range of breath frequency corresponding to the medium level is 20-21 times / min, the range of breath frequency corresponding to the high level is 22-23 times / min, and the range of breath frequency corresponding to the high level is 24 times or more. In the case that the lung breath frequency rises from 16 times / min to 20 times / min, the first activity level changes from low level to medium level.

[0086] It can be understood that the second preset activity level set includes a plurality of preset activity levels, and the second preset activity level set is used to represent all levels corresponding to the body temperature parameter. For example, the first preset activity set includes four levels, which are low level, medium level, high level and high level. Among them, the range of body temperature corresponding to the low level is below 37℃, the range of body temperature corresponding to the medium level is 37℃-38℃, the range of body temperature corresponding to the high level is 38℃-39℃, and the range of respiratory frequency corresponding to the high level is above 39℃. In the case that the body temperature decreases from 38℃ to 37℃, the second activity level changes from medium level to low level.

[0087] It can be understood that the third preset activity level set includes a plurality of preset activity levels, and the third preset activity level set is used to represent all levels corresponding to the exercise intensity parameter. For example, the third preset activity set includes four levels, which are low level, medium level, high level and high level. Among them, the range of exercise intensity corresponding to the low level is the exercise intensity corresponding to sleep or sitting, the range of exercise intensity corresponding to the medium level is the exercise intensity of light physical exercise such as walking, the range of exercise intensity corresponding to the high level is the exercise intensity of medium physical exercise such as fast walking, and the range of exercise intensity corresponding to the high level is the exercise intensity corresponding to long-distance running or heavy physical labor. In the case that the exercise intensity changes from fast walking to walking, the third activity level changes from high level to medium level.

[0088] Among them, the number of levels included in the first preset activity level set, the second preset activity level set and the third preset activity level set can be the same or different, which will be described in detail in subsequent embodiments.

[0089] In the embodiments of the application, the first activity level is determined by the first preset activity level set, and / or the second activity level is determined by the second preset activity level set, and / or the third activity level is determined by the third preset activity level set, and then the target activity level is determined to realize the adjustment of the beating speed of the artificial heart.

[0090] In one embodiment, the target speed level is determined according to at least one of the first preset activity level, the second preset activity level and the third preset activity level, comprising:

[0091] In the case that at least two of the lung respiratory frequency parameter, the body temperature parameter and the body exercise intensity parameter, the lowest to highest activity parameter range in all or at least one of the first activity level, the second activity level and the third activity level is set to different levels of the target speed.

[0092] In the case that the physical activity parameter includes at least two of the lung breath frequency parameter, the body temperature parameter and the exercise intensity parameter, the highest activity level of at least two of the first activity level, the second activity level and the third activity level is set as the target activity level, and the parameter included in the physical activity parameter corresponds to the activity level of the at least two. For example, the physical activity parameter includes the lung breath frequency parameter and the body temperature parameter, and the activity level includes the first activity level and the second activity level.

[0093] It can be understood that the highest activity level of at least two of the first activity level, the second activity level and the third activity level is set as the target activity level, and the beating speed corresponding to the highest activity level can meet the requirements of all physical activities. For example, the beating speed corresponding to the first activity level is 80 times / min, and the beating speed corresponding to the second activity level is 70 times / min. At this time, the first activity level should be set as the target activity level, and the beating speed is controlled to accelerate to 80 times / min, so as to meet the blood supply of lung breath and the blood supply of body temperature change.

[0094] It can be understood that the different preset activity levels include different numbers of levels, and there is a corresponding relationship between the different preset activity levels. For example, the first preset activity level includes three levels, the second preset activity level includes four levels, and the third preset activity level includes five levels, and the levels of the different preset activity levels correspond to each other. For example, the first preset activity level includes a first level, a second level and a third level, the second preset activity level includes a low level, a middle level, a high level and a high level, the first level of the first preset activity corresponds to the low level of the second preset activity, the second level of the first preset activity corresponds to the middle level and the high level of the second preset activity, and the third level of the first preset activity corresponds to the high level of the second preset activity.

[0095] In the case that the physical activity parameter includes the lung breath frequency parameter and the body temperature parameter, the first activity level is the second level, and the second activity level is the high level. At this time, the second activity level is the highest level, the target activity level is set as the second activity level, and the beating speed of the artificial heart is adjusted based on the second activity level.

[0096] In the embodiment of the present application, in the case that the physical activity parameter includes at least two of the lung breath frequency parameter, the body temperature parameter and the exercise intensity parameter, the highest activity level of at least two of the first activity level, the second activity level and the third activity level is set as the target activity level, so as to realize that the beating speed of the artificial heart meets the requirements of all organs of the user.

[0097] In one embodiment, the beating speed of the artificial bionic heart should be not less than an initial heartbeat speed, and the initial heartbeat speed is determined according to the single pumping volume of the artificial bionic heart, the height, the weight and / or the gender of the user.

[0098] It can be understood that the beating speed of the artificial bionic heart needs to be adjusted for different activity levels.

[0099] In one embodiment, the beating speed of the artificial bionic heart is not less than an initial setting speed, and the initial setting speed is determined according to the blood pumping volume, height, weight and / or gender of the user of the artificial bionic heart.

[0100] It can be understood that an initial speed needs to be set when the artificial bionic heart is implanted into the user. The initial speed set for different users is different, and in this embodiment, the initial speed is determined according to the blood pumping volume, height, weight and / or gender of the user.

[0101] For example, the setting range of the initial speed is 60-90 times / min, wherein 60 times / min corresponds to an adult female user of 1.45 meters or more in height and 50 kg or less in weight, and an adult male user of 1.50 meters or more in height and 60 kg or less in weight. For example, in the case where the weight of the user increases by 1 kg, the initial speed is increased by 1 time / min; in the case where the weight of the female user is greater than or equal to 80 kg, or the weight of the male user is greater than or equal to 90 kg, the initial speed is set to 90 times / min.

[0102] In one embodiment, the setting range of the initial speed and the weight corresponding to the initial speed are flexibly set, including but not limited to the above-mentioned embodiments.

[0103] In one embodiment, the initial speed represents the minimum running speed of the artificial bionic heart required by the user when resting or sitting, and the beating speed of the artificial bionic heart needs to be adjusted on the basis of the initial speed in different activity situations.

[0104] For example, the adjustment coefficient is different, and the speed corresponding to different target activity levels is different. In the case where the activity level is 4 levels, the corresponding speed is shown in the following table:

[0105]

[0106]

[0107] In one embodiment, the initial speed, the first target speed, the second target speed and the third target speed are the speeds corresponding to the four activity levels, respectively. It should be understood that a plurality of target speeds can be set according to the actual application, such as the first target speed, the second target speed and the third target speed shown in the above table.

[0108] Exemplarily, different initial speeds correspond to different adjustment coefficients, and the adjustment coefficient decreases regularly by 0.003 as the initial speed increases by 1 time / min, wherein the regular change of the setting range of the initial speed and the increase or decrease of the adjustment coefficient includes but is not limited to the manner provided in the above embodiment.

[0109] In the embodiment of the application, the initial speed is determined according to the blood pumping volume, height, weight and / or gender of the user, so as to meet the needs of different users in different physical conditions, and improve the safety of the artificial bionic heart.

[0110] In one embodiment, the method further comprises:

[0111] In the set time, the artificial bionic heart is controlled to linearly transition from the current speed to the target speed.

[0112] In the above embodiment, the method further comprises:

[0113] In the first set time, the artificial bionic heart is controlled to linearly transition from the current beating speed to the first target speed.

[0114] In the second set time, the artificial bionic heart is controlled to linearly transition from the current beating speed to the second target speed.

[0115] In the above embodiment, the first set time and the second set time are set according to experience, and the first set time can be the same as or different from the second set time. For example, the first set time is 3 min, and the second set time is 3 min, the artificial bionic heart is controlled to linearly accelerate from the current beating speed to the first target speed in 3 min, or the artificial bionic heart is controlled to linearly accelerate from the current beating speed to the second target speed in 3 min.

[0116] It should be particularly noted that when the heart rate increases, the time for reaching the target activity level matching the heart rate is 3 min, regardless of the number of speed increases. When the heart rate decreases, each decrease in speed needs 3 min to complete, and if the heart rate decreases by three speeds in succession, it needs 9 min to complete.

[0117] In the embodiment of the application, in the first set time, the artificial bionic heart is controlled to linearly transition from the current beating speed to the first target speed, and / or in the second set time, the artificial bionic heart is controlled to linearly transition from the current beating speed to the second target speed, so as to avoid the situation that the user's body cannot adapt to the sudden change of the beating speed.

[0118] In one embodiment, the method further comprises:

[0119] acquiring a monitoring parameter, the monitoring parameter comprising at least one of a battery power parameter, a motor operation parameter, a received power parameter, and a circuit board chip operation parameter;

[0120] judging whether the artificial bionic heart is in an abnormal state based on the monitoring parameter;

[0121] in a case where the artificial bionic heart is in the abnormal state, instructing the artificial bionic heart to change into a safe guarantee mode, the safe guarantee mode being used to ensure the safety of a user;

[0122] after the artificial bionic heart enters the safe guarantee mode, according to the monitoring parameter, sending target early warning information to an early warning system, the target early warning information being used to indicate that the artificial bionic heart is in the abnormal state.

[0123] It can be understood that the artificial bionic heart is usually internally provided with a battery for power supply, or an external wireless charger is provided to supply power to the artificial bionic heart and charge the internal battery. Since the artificial bionic heart needs to continuously work to supply blood, the battery power cannot be lower than a set value, and therefore the battery parameter needs to be monitored. When the battery power is lower than the set value, the system should automatically charge in time and send target early warning information.

[0124] For example, in a case where the external wireless charger supplies power to the artificial bionic heart, when the external wireless charger stops supplying power to the artificial bionic heart, the internal battery should supply power to the artificial bionic heart. In the embodiment of the present application, based on the early warning of the battery parameter, the early warning information can be sent through a display lamp and / or voice alarm, and the user is reminded to charge the battery in time.

[0125] In one embodiment, the monitoring parameter comprises at least one of a power parameter and a time parameter of a distance from the last charging completion, and the target early warning information comprises first early warning information and second early warning information.

[0126] the early warning information comprises at least one of the following:

[0127] In the case that the electric quantity parameter is less than a first set threshold value, and / or the time parameter is greater than a second set threshold value, the battery of the artificial bionic heart is controlled to be charged, or a safe operation mode is entered, and a first warning information is sent, which is used to indicate that the battery of the artificial bionic heart needs to be charged. For example, when the circuit board sensing chip of the external device does not charge the internal battery for more than 2 hours (including when the internal battery has only 80% of the electric quantity), the warning device should immediately sound an alarm to remind the user to charge immediately. At the same time, when the integrated module being used is away from the user's body for more than 2 hours (mainly considering the time required for the user to take a bath or swim), the warning device of the integrated module should sound an alarm to remind the user not to leave the warning device for too long.

[0128] In the case that the electric quantity parameter is less than a third set threshold value, the battery of the artificial bionic heart is controlled to be charged, or a safe operation mode is entered, and a second warning information is sent, which is used to indicate that the external power supply battery of the artificial bionic heart needs to be replaced or charged.

[0129] It can be understood that the electric quantity parameter represents the remaining electric quantity of the internal battery of the artificial bionic heart, and the first set threshold value is a preset battery threshold value. In the case that the electric quantity parameter is less than the first set threshold value, the safe operation mode needs to be entered, and the first warning information is sent to remind the user to charge the internal battery.

[0130] For example, when the internal battery is fully charged, the internal battery stops charging, and the external wireless charger directly supplies power to the motor of the artificial bionic heart, so that the motor directly uses the power of the wireless charger to work normally.

[0131] The time for a full charge is preferably not more than 4 hours, and the working time of the internal battery is preferably not less than 10 hours, so as to avoid the problem that the artificial bionic heart cannot work due to the inability to charge externally, for example, the user needs to swim or take a bath and cannot charge. In order to improve safety, the internal battery and the motor are connected through a separate line.

[0132] It can be understood that the second set threshold value is a preset time threshold value, and in the case that the time parameter is greater than the second set threshold value, the safe operation mode needs to be entered, and the first warning information is sent to remind the user to immediately charge the internal battery using the external charging device.

[0133] It can be understood that the third setting threshold is a battery damage threshold, when the battery parameter is less than the third setting threshold, the capacity of the battery cannot meet the normal use, or the battery cannot be charged abnormally, at this time, the safe operation mode needs to be entered, and the second early warning information is sent to remind the user to go to the hospital to replace the built-in battery and equipment.

[0134] Among them, the artificial bionic heart can be set as a double power system, a double communication system, a double software system and a double early warning system, when one of the systems cannot be used abnormally, the other system is used; or, the double systems can be used in different time periods to improve the service life. Among them, when one of the systems is abnormal, the safe operation mode needs to be entered, and the third early warning information is sent to remind the user to go to the hospital for examination or replacement to ensure life safety.

[0135] In the embodiment of the application, the first early warning information or the second early warning information is sent through the battery parameter and the preset first setting threshold, the second setting threshold and the third setting threshold, reminding the user to handle in time, and the safety of the artificial bionic heart is improved.

[0136] In one embodiment, the control of the battery charging of the artificial bionic heart, or the entering of the safe operation mode and the sending of the second early warning information, comprises:

[0137] In the case that the power parameter decreases by a set power from the third setting threshold, the control of the battery charging of the artificial bionic heart, or the entering of the safe operation mode and the sending of the second early warning information.

[0138] For example, the third setting threshold is 80%, if the built-in battery power is lower than 80% and still cannot be charged, the second early warning information is sent when the battery power is lower than 80%, 70%, 60%, 50%, 40%, 30%, 20% and 10% to prompt the user to go to the hospital for examination or replacement quickly to ensure life safety.

[0139] In one embodiment, the early warning information comprises at least one of display lamp information and loudspeaker voice information.

[0140] It can be understood that the display lamp information or the loudspeaker voice information is used for early warning to improve the effect of early warning and ensure that the user receives the early warning information.
