Description

Technical Field

[0001] The invention belongs to the field of intelligent wearable devices, and in particular is an automatic pressurization and pressure measurement intelligent abdominal belt device. Background Art

[0002] Orthostatic hypotension (OH) is a common non-motor symptom of Parkinson's disease. Its diagnostic criteria are that the systolic blood pressure drops by ≥20 mmHg (1 mmHg = 0.133 Kpa) and (or) the diastolic blood pressure drops by ≥10 mmHg within 3 minutes from lying to standing. Orthostatic hypotension can occur at any time point in the entire course of Parkinson's disease and has become a key factor that seriously affects the quality of life of patients. The occurrence of orthostatic hypotension is due to pathological changes in the area of ​​the Parkinson's disease nerve center that controls the autonomic nervous function. When the body position changes, it manifests as sympathetic inhibition. Therefore, the mesenteric and portal vein vessels dilate, a large amount of blood accumulates, the amount of blood returning to the heart is reduced, the cardiac output decreases, and normal blood pressure cannot be maintained. Orthostatic hypotension can impair the cognitive function of Parkinson's patients and aggravate motor symptoms. In severe cases, it can lead to adverse events such as syncope and falls, threatening the safety of patients. Therefore, it is particularly important for Parkinson's patients with orthostatic hypotension to avoid a drop in blood pressure in the upright position.

[0003] Since drug therapy alone can easily cause serious cardiovascular side effects, the Expert Consensus on Screening, Diagnosis and Treatment of Neurogenic Orthostatic Hypotension and Related Supine Hypertension advocates non-drug therapy as the first choice for treating postural hypotension in Parkinson's patients. Abdominal compression therapy, which uses an abdominal belt to apply pressure to the abdomen, squeezes part of the abdominal blood into the chest cavity, and at the same time reduces the diameter of the abdominal blood vessels, reduces the blood volume of this part, and increases the amount of blood returning to the heart, has been widely studied and applied to effectively prevent the drop in upright blood pressure. Existing abdominal belt products mainly achieve the pressurization effect through elastic belt pressurization or manual inflation of air bags. Elastic belt pressurization mainly adjusts the tightness of the abdominal belt according to personal experience and feeling to control the abdominal pressurization effect, while manual inflation with air bags can only be quantitatively inflated, and it is difficult to adjust and maintain effective pressure.

[0004] Therefore, it is necessary to propose an automatic pressure-adding and pressure-measuring intelligent abdominal belt device which can intelligently open and adjust the effective pressure of the abdominal belt according to the specific physical condition of the wearer. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide an automatic pressurization and pressure measurement intelligent abdominal belt device, which detects the wearer's physical condition through a motion sensing component and a blood pressure detection component, and the controller predicts the risk of orthostatic hypotension, controls the inflation of the pressurized airbag component to pressurize the abdominal cavity, and adjusts the pressure of the airbag abdominal cavity according to the pressure sensor data, thereby reducing the probability of orthostatic hypotension and the severity of symptoms.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an automatic pressurization and pressure measurement intelligent abdominal belt device, comprising an abdominal belt body, the abdominal belt body is provided with a belt length adjuster and a first battery, a skin-friendly layer is fixedly connected to the inner side of the abdominal belt body, and a pressurization airbag component, an oxygenation airbag component, a pressure sensor, a motion sensing component, a controller and a first wireless component are provided between the abdominal belt body and the skin-friendly layer;

[0007] The belt length adjuster is used to adjust the length of the belly belt body to a comfortable wearing range for the wearer according to the preset waist circumference of the wearer and lock it;

[0008] The motion sensing component is used to detect the wearer's motion state;

[0009] The controller is used to obtain the movement state of the wearer's body from the motion sensing component to predict the risk of orthostatic hypotension. When orthostatic hypotension is predicted to occur, the controller controls the pressurized airbag component to pressurize the wearer's abdominal cavity based on the pressure sensor data;

[0010] The pressurized airbag assembly is used to pressurize the wearer's abdominal cavity and squeeze blood into the chest cavity when orthostatic hypotension is predicted to occur;

[0011] The oxygen bag assembly is used to spray oxygen around the wearer's upper body when orthostatic hypotension is predicted.

[0012] The principle of the basic solution is: the controller controls the belt length adjuster to shorten the length of the belly belt body according to the preset waist circumference of the wearer, so that the wearer can wear the belly belt body more comfortably in daily life. Since postural hypotension mainly occurs when the wearer's body position changes, the motion sensing component detects the wearer's motion state, and the controller combines the motion state data with the blood pressure change data to predict the occurrence of postural hypotension and control the pressurized airbag component to start pressurizing the wearer's abdominal cavity. During the pressurization process, the controller adjusts the pressure applied by the pressurized airbag component based on the pressure sensor data, stably maintains the abdominal cavity pressure, and presses blood into the chest cavity to reduce the probability and severity of postural hypotension. While the pressurized airbag component is inflated and pressurized, it will also squeeze the oxygen bag component, and squeeze the oxygen filled in the oxygen bag component into the wearer's upper body, indirectly replenishing oxygen to the brain and alleviating the symptoms of postural hypotension.

[0013] The beneficial effects of the basic scheme are: 1. This scheme can automatically adjust the length of the belly band body through the preset waist circumference of the wearer so that the tightness is within a more comfortable range for the wearer, reducing the number of manual adjustments by the wearer, saving manpower and time for adjusting the length, and also enhancing the adaptability of the belly band body among patients and elderly wearers.

[0014] 2. This solution senses the wearer's motion state through the motion sensing component, and the controller controls the pressurized airbag component to start abdominal pressurization based on the blood pressure change data, reducing the instruments and manpower used to monitor the wearer's physiological condition, saving manpower, and at the same time enhancing the timeliness of the abdominal belt's body to pressurize the abdominal cavity, preventing postural hypotension for the wearer.

[0015] 3. This solution uses a controller to adjust the intensity of the pressurized airbag assembly to pressurize the wearer's abdominal cavity based on the pressure sensor data, which can accurately control the abdominal cavity pressure within a reasonable range. On the basis of alleviating the symptoms of orthostatic hypotension, it can avoid excessive abdominal cavity pressure causing blood vessel obstruction and also avoid too little abdominal cavity pressure to have no effect.

[0016] Furthermore, the automatic pressurization and pressure measurement intelligent abdominal belt device also includes a wristband, which is provided with a display terminal, a second battery, a blood pressure detection component and a second wireless component. The display terminal is connected to the controller signal through the first wireless component. The controller is used to obtain the wearer's blood pressure change data from the blood pressure detection component, predict the risk of orthostatic hypotension, and output the obtained data and prediction results to the display terminal for display.

[0017] The beneficial effects of the basic solution are: this solution can monitor the wearer's blood pressure changes through the blood pressure detection component on the bracelet and transmit the data to the controller through the second wireless component to predict the risk of orthostatic hypotension, improve the data collection for orthostatic hypotension prediction, and improve the accuracy of orthostatic hypotension prevention. In addition, the small bracelet will not interfere with the wearer's daily life.

[0018] Furthermore, a second inertial sensor is provided on the bracelet, and the second inertial sensor is connected to the controller signal through a second wireless component.

[0019] The beneficial effect of the basic scheme is: this scheme can detect the frequency of hand tremors of the wearer's Parkinson's disease patient through the second inertial sensor on the bracelet, and transmit the data of the second inertial sensor to the controller to determine the changes in the severity of the Parkinson's disease patient's symptoms, and remind the patient to take medicine and seek medical treatment. Since orthostatic hypotension is more likely to occur in severe cases of Parkinson's disease, the controller will lower the sensitivity threshold for predicting orthostatic hypotension as the severity of Parkinson's disease worsens, adaptively preventing the occurrence of orthostatic hypotension and reducing the severity of symptoms.

[0020] Furthermore, the belt length adjuster includes an abdominal belt storage box, in which an abdominal belt winch shaft is provided, one end of the abdominal belt body is wound around the winch shaft, and the winch shaft is provided with a driving member and a locking member for driving the winch shaft to rotate. The controller is used to control the winch shaft to rotate, tighten the abdominal belt, control the tightness and lock it according to the preset wearer's waist circumference and pressure sensor data.

[0021] The beneficial effect of the basic scheme is that the belt length adjuster can automatically adjust the length of the belly belt according to the wearer's waist circumference preset by the controller through an electric drive member and a locking member, thereby reducing manual operation costs and expanding the adaptability of the belly belt body for use by wearers in different situations.

[0022] Furthermore, the pressurized airbag assembly includes an annular airbag, a pressure sensor is fixedly connected to the outer wall of the annular airbag near the wearer's abdomen, a plurality of electric air pumps are connected to the bottom of the annular airbag, and a ventilation tube is connected to one end of the electric air pump away from the annular airbag, and the ventilation tube passes through the abdominal belt body to connect to the outside world.

[0023] The beneficial effects of the basic scheme are: this scheme uses an electric air pump to inflate the annular airbag and then pressurize the wearer's abdominal cavity, which can relatively quickly increase the abdominal pressure, promptly relieve the symptoms of orthostatic hypotension, and avoid manual inflation and pressurization of the annular airbag, saving human resources.

[0024] Furthermore, the oxygen filling bag assembly includes a "C"-shaped air bag, the "C"-shaped air bag covers the wearer's abdomen, one end of the "C"-shaped air bag is connected to an oxygen filling valve, the oxygen filling valve passes through the abdominal belt body to connect to the outside world, the "C"-shaped air bag is located on the top of the annular air bag, the top of the "C"-shaped air bag is connected to a plurality of one-way air valves, the ends of the one-way air valves away from the "C"-shaped air bag are connected to an oxygen tube, and the oxygen tube passes through the abdominal belt body to connect to the outside world.

[0025] The beneficial effect of the basic scheme is: this scheme can use the oxygenation bag assembly to squeeze the "C"-shaped airbag by inflating the annular airbag when the pressurized airbag assembly is activated, and squeeze the oxygen upward and disperse it into the air around the wearer's upper body, thereby increasing the oxygen content of the wearer's breathing, indirectly increasing the wearer's brain supply, preventing orthostatic hypotension, and enhancing the effect of the abdominal belt itself in relieving the symptoms of orthostatic hypotension.

[0026] Further, the motion sensing component includes a gyroscope and a first inertial sensor.

[0027] The beneficial effect of the basic scheme is: this scheme can detect the wearer's torso movement and movement status through the gyroscope and the first inertial sensor, and can provide the controller with relatively comprehensive data to determine whether the relevant torso movement will cause orthostatic hypotension symptoms. It is the data basis for the abdominal belt body to prevent orthostatic hypotension.

[0028] Furthermore, the display terminal is used to preset the wearer's abdominal circumference, daily blood pressure and illness time data, and display the data and prediction results of the gyroscope, the first inertial sensor, the pressure sensor, the blood pressure detection component and the second inertial sensor acquired by the controller.

[0029] The beneficial effects of the basic solution are: this solution presets the wearer's basic physical data through the display terminal, allowing the controller to customize the orthostatic hypotension prevention mechanism with different sensitivity levels according to the wearer, improve the pertinence of the abdominal belt body to different wearer conditions, and optimize the prevention and relief of orthostatic hypotension. At the same time, the wearer and medical staff can also monitor and understand changes in the wearer's physical condition through the display terminal, providing a basis for the improvement of subsequent medical plans.

[0030] Furthermore, the automatic pressurization and pressure measurement intelligent abdominal belt device also includes a temperature control component, which is used to heat the air pumped into the annular airbag by the electric air pump.

[0031] The beneficial effects of the basic scheme are: this scheme heats the air pumped into the annular airbag through the temperature control component, thereby improving the comfort of the wearer, avoiding other discomfort symptoms caused by abdominal cold, and improving the adaptability of the abdominal belt body to Parkinson's patients and the elderly.

[0032] Furthermore, the automatic pressurization and pressure measurement intelligent abdominal belt device also includes an oxygenation component, which is used to replenish oxygen for the oxygenation bag component after use. The oxygenation component includes an oxygen cylinder, which is connected to an oxygenation tube. An oxygen valve is connected between the oxygen cylinder and the oxygenation tube, and a barometer is provided on the oxygen valve.

[0033] The beneficial effects of the basic scheme are: this scheme supplements oxygen to the oxygenation component through the automatic oxygenation component, maintains the purity of oxygen in the "C"-shaped airbag, and improves the efficiency of indirect prevention of orthostatic hypotension.

DETAILED DESCRIPTION

[0039] The following is further described in detail through specific implementation methods:

[0040] Example 1

[0041] Basically as attached Figure 1 , Figure 2 and Figure 3 As shown: an automatic pressurization and pressure measurement intelligent abdominal belt device includes an abdominal belt body 11, a belt length adjuster and a first battery 5 are bonded to the abdominal belt body 11, a skin-friendly layer 7 is bonded to the inner side of the abdominal belt body 11, and the skin-friendly layer 7 improves the tactile experience when wearing the abdominal belt, and a pressurized airbag component, an oxygenating airbag component, a pressure sensor, a motion sensing component 3, a controller 4 and a first wireless component 6 are bonded between the abdominal belt body 11 and the skin-friendly layer 7, and the pressure sensor and the motion sensing component 3 are connected to the controller 4 signal through the first wireless component 6.

[0042] The belt length adjuster is used to adjust the length of the belly belt body 11 to the comfortable wearing range of the wearer according to the preset waist circumference of the wearer and lock it. The belt length adjuster includes a belly belt receiving box 12. The pin shaft in the belly belt receiving box 12 is connected to the belly belt winch shaft 1. One end of the belly belt body 11 is wound around the winch shaft 1. The winch shaft 1 is welded with a driving member 2 and a locking member for driving the winch shaft 1 to rotate. The controller 4 is used to control the winch shaft 1 to rotate and tighten the belly belt according to the preset waist circumference of the wearer and the pressure sensor data to control the tightness and lock it.

[0043] The motion sensing component 3 is used to detect the motion state of the wearer, and the motion sensing component 3 includes a gyroscope and a first inertial sensor;

[0044] The controller 4 is used to obtain the movement state of the wearer's body from the motion sensing component 3 to predict the risk of postural hypotension. When postural hypotension is predicted to occur, the controller 4 controls the pressurized airbag component to pressurize the wearer's abdominal cavity based on the pressure sensor data;

[0045] The pressurized airbag assembly is used to pressurize the wearer's abdominal cavity and squeeze blood into the chest cavity when postural hypotension is predicted to occur. The pressurized airbag assembly includes an annular airbag 9, a pressure sensor is bonded to the outer wall of the annular airbag (9) close to the wearer's abdomen, and the bottom of the annular airbag 9 is bonded to a plurality of electric air pumps 14, and the ends of the electric air pumps 14 away from the annular airbag 9 are bonded to a ventilation tube 13, and the ventilation tube 13 passes through the abdominal belt body 11 to communicate with the outside world;

[0046] The oxygenation bag assembly is used to increase the oxygen content of the air around the wearer's upper body when postural hypotension is predicted to occur. The oxygenation bag assembly includes a "C"-shaped airbag 8, the "C"-shaped airbag 8 covers the wearer's abdomen, one end of the "C"-shaped airbag 8 is bonded and connected to an oxygen filling valve 10, and the oxygen filling valve 10 passes through the abdominal belt body 11 to communicate with the outside world, the "C"-shaped airbag 8 is located on the top of the annular airbag 9, and a plurality of one-way air valves 16 are bonded and connected to the top of the "C"-shaped airbag 8, and one end of the one-way air valve 16 away from the "C"-shaped airbag 8 is bonded and connected to an oxygen pipe 15, and the oxygen pipe 15 passes through the abdominal belt body 11 to communicate with the outside world;

[0047] The automatic pressurization and pressure measurement intelligent abdominal belt device also includes a temperature control component 17 and an oxygenation component. The temperature control component 17 is used to heat the air pumped into the annular airbag 9 by the electric air pump 14. The oxygenation component is used to replenish oxygen for the oxygenation bag component after use. The oxygenation component includes an oxygen cylinder, which is connected to an oxygenation tube. An oxygen valve is connected between the oxygen cylinder and the oxygenation tube, and a barometer is provided on the oxygen valve.

[0048] The specific implementation process is as follows: before the Parkinson's disease patient wears the belly belt, the wearer's basic physical condition data is preset, and then the belly belt is worn to the abdomen. Under the control of the controller 4, the belt length adjuster on the belly belt adjusts the length of the belly belt body 11 to the wearer's comfortable wearing range based on the preset wearer's waist circumference data and locks it.

[0049] After that, the wearer lives a normal life. When the wearer's body position changes, the gyroscope and the first inertial sensor in the motion sensing component 3 will detect the wearer's torso movement and movement status data and transmit them to the controller 4. The controller 4 combines the torso movement and movement status data and the wearer's blood pressure change data to predict the wearer's risk of developing orthostatic hypotension symptoms. If the risk level is high, the first battery 5 supplies power and the controller 4 controls the pressurized airbag component to start. The electric air pump 14 in the pressurized airbag component draws air from the bottom of the belly band and fills it into the annular airbag 9 to pressurize the wearer's abdominal cavity, compressing the blood in the abdominal cavity to accelerate the return to the chest cavity, preventing and alleviating the occurrence of orthostatic hypotension symptoms. The temperature control component 17 is a section of electric heating wire that will promptly heat the gas pumped in by the electric air pump 14 to maintain the gas temperature in the annular airbag 9 close to the body surface temperature. At the same time, the "C"-shaped airbag 8 in the oxygen bag assembly on the top of the annular airbag 9 will be squeezed during the inflation process, and the pre-filled oxygen in the "C"-shaped airbag 8 will be squeezed out from the one-way air valve 16 and scattered around the wearer's upper body, thereby increasing the oxygen content inhaled by the wearer, supplementing the oxygen supply to the brain, and indirectly alleviating the brain hypoxia symptoms caused by orthostatic hypotension.

[0050] Since general orthostatic hypotension symptoms will last for about 3 minutes, the pressurized airbag assembly needs to maintain pressurization of the wearer's abdominal cavity for about 5 minutes. During this process, the pressure sensor on the annular airbag 9 will continuously detect the abdominal cavity pressurization data and transmit it to the controller 4. The controller 4 controls the electric air pump 14 in the pressurized airbag assembly to inhale or deflate to adjust the expansion degree of the annular airbag 9 based on the abdominal cavity pressurization data control and blood pressure change data, thereby adjusting the pressure of the pressurized airbag assembly on the wearer's abdominal cavity, so that the abdominal cavity pressurization is maintained within an appropriate and stable range.

[0051] Example 2

[0052] The difference from the above embodiment is that, as shown in the attached Figure 4 As shown: the automatic pressurization and pressure measurement intelligent abdominal belt device also includes a wristband, which is provided with a display terminal 18, a second battery 19, a blood pressure detection component 22, a second wireless component 20 and a second inertial sensor 21. The display terminal 18 is connected to the controller 4 signal through the first wireless component, and the blood pressure detection component 22 and the second inertial sensor 21 are connected to the controller 4 signal through the second wireless component 20. The controller 4 is used to obtain the wearer's blood pressure change data from the blood pressure detection component 22 to predict the risk of orthostatic hypotension, and to obtain the wearer's hand tremor frequency data from the second inertial sensor 21 to determine the change in the degree of Parkinson's disease of the wearer. The controller 4 outputs the obtained data and prediction results of the gyroscope, the first inertial sensor, the pressure sensor, the blood pressure detection component 22 and the second inertial sensor 21 to the display terminal 18 for display.

[0053] The specific implementation process is as follows: When the Parkinson's disease patient wears the belly band, he / she also wears the wristband powered by the second battery 19. The wearer first presets his / her basic physical condition on the display terminal 18 of the wristband, and the blood pressure detection component 22 on the wristband continuously detects the wearer's blood pressure change data. The blood pressure change data is transmitted to the controller 4 through the second wireless component 20 as an important basis for predicting postural hypotension (the preset diagnostic standard for postural hypotension is: systolic blood pressure drop ≥ 20 mmHg, or diastolic blood pressure drop ≥ 10 mmHg). The second inertial sensor 21 on the wristband continuously detects the wearer's blood pressure change data. The wearer's hand tremor frequency data is measured and transmitted to the controller 4 through the second wireless component 20 to determine whether the wearer's Parkinson's disease has worsened. According to the severity of the wearer's Parkinson's disease, the controller 4 will make corresponding reminders through the display terminal 18, and will adjust the sensitivity threshold of the controller 4 for postural hypotension prediction. This means that in the case of severe Parkinson's disease, the controller will be more inclined to predict that postural hypotension is about to occur, thereby activating the pressurized airbag component to pressurize the wearer's abdominal cavity, thereby enhancing the pertinence and adaptability of the abdominal belt body 11 to wearers with different degrees of Parkinson's disease.

[0054] In addition, the sensor data acquired by the controller 4 will be transmitted to the display terminal 18 through the first wireless component 6 for display, so as to facilitate the wearer and medical staff to understand the changes in the patient's symptoms and serve as a basis for subsequent treatment plans.
