Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation equipment, and in particular to an external counterpulsation rehabilitation therapeutic apparatus and a control method thereof. Background Art

[0002] Diabetic foot is an ischemic, neurological and neuroischemic lesion of the foot caused by diabetes. In the early stage, it manifests as symptoms of insufficient blood supply such as cold lower limbs, decreased foot skin temperature, pain, and peripheral neuropathy symptoms such as paralysis and dullness. In the late stage, necrosis of foot muscle and bone tissue occurs, such as osteomyelitis, dry or wet gangrene, and severe symptoms such as amputation have to be performed. Diabetic foot can lead to limited walking and lifelong disability of patients, seriously affecting physical and mental health and quality of life. In recent years, the incidence rate in my country has been increasing.

[0003] In clinical practice, diabetic foot is divided into grades 0 to 5 according to the Wagner classification. Even at the lightest grade 0, the patient's lower limbs and feet already have significant poor blood flow, insufficient perfusion, and neuropathy. Therefore, improving the hemodynamics of the patient's lower limbs and feet plays a decisive role in the prevention, treatment, and rehabilitation of diabetic foot.

[0004] At present, the clinical treatment of diabetic foot mainly includes: 1) blood sugar control; 2) drug therapy; 3) antiplatelet and vasodilator therapy; 3) non-invasive auxiliary circulation therapy such as air pressure wave; 4) lower limb arterial intravascular interventional therapy and vascular bypass surgery; 5) amputation surgery, etc.

[0005] Among them, drug therapy is extremely effective in improving the hemodynamic environment of the lower limbs and feet; interventional surgery is very expensive, and diabetic patients are prone to local thrombosis and new occlusions after stent surgery. In addition, it is difficult to pass the guidewire through the vascular occlusion below the knee, and the occlusion of small blood vessels and micro-vessels in the lower legs and feet is not suitable for interventional treatment. The nature of the air pressure wave therapy device is no different from lower limb massage. Since it does not actually increase the blood supply to the lower limbs, its hemodynamic effect is also extremely limited.

[0006] Since the original design purpose of EECP was to rescue patients with myocardial infarction, the three-level counterpulsation mode from distal to proximal and the immediate efficacy judgment standard of D / S ratio ≥1.2 used at home and abroad can maximize the return of blood and coronary artery blood supply, while ensuring the blood supply of important organs in the upper body. However, for the hemodynamic promotion of the lower body, especially the lower limbs and feet, the above working mode and standard may not achieve the optimal effect. Therefore, it is necessary to design a new counterpulsation intervention mode to meet the clinical needs of promoting hemodynamics in the lower body.

[0007] In addition, diabetic foot patients generally have difficulty walking, and the early symptoms are mild and not easy to attract enough attention, which leads to the gradual deterioration of the disease and serious consequences. Therefore, positioning EECP treatment as a secondary prevention / rehabilitation goal and delegating it to community health service centers and families is more conducive to early prevention, early intervention and prognosis and rehabilitation of patients. However, due to its inherent characteristics, the current clinical EECP devices are not suitable for use in community health and families, mainly including: 1) large and bulky, the counterpulsation bed covers an area of ​​nearly two square meters and weighs more than 200kg; 2) high power consumption, high noise, and high heat generation. Clinical EECP devices generally approach or even exceed 2.5 kWh, and the da-power air pump causes significant noise; 3) For patients with ulcers in the calf or foot, the calf cuff may cause adverse events in the ulcer area. Summary of the invention

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 to Figure 2As shown, the external counterpulsation rehabilitation therapeutic apparatus according to an embodiment of the present invention includes a host 100 and a counterpulsation airbag assembly (not shown); the host 100 includes a housing 10 having a housing cavity and a main control module 20, a power module 30, a data acquisition module 40, a wireless communication module 50, a counterpulsation control module 60 and an air source assembly 200 arranged in the housing cavity, the main control module 20 is respectively connected to the power module 30, the data acquisition module 40, the wireless communication module 50 and the counterpulsation control module 60, and the air source assembly 200 00 includes an air pump 201, an air tank 202, a solenoid valve group and multiple air pipe interfaces 204. The air inlet end of the air tank 202 is connected to the air pump 201 through a pipeline, and the air outlet end of the air tank 202 is connected to the multiple air pipe interfaces 204 through the solenoid valve group. The multiple air pipe interfaces 204 are arranged on the outer wall of the shell 10, and the counterpulsation control module 60 is electrically signal connected to the air pump 201 and the solenoid valve group respectively; the counterpulsation airbag assembly includes three groups of airbags that are detachably connected to the multiple air pipe interfaces 204 through pipelines.

[0037] The wireless communication module 50 can be an antenna, and the data acquisition module 40 is connected to the external ECG, blood pressure, pulse and finger pulse monitoring equipment through the wireless communication module 50, so as to obtain the patient's human physiological data signals, and the traditional cumbersome data line connection work and the interference and inconvenience of the connection to the treatment process are reduced by the wireless connection method; of course, the host 100 can also be provided with a data interface, which is suitable for traditional monitoring equipment without wireless communication. The airbag of the counterpulsation airbag assembly is an existing conventional bag sleeve, which is used to be set on the patient's calf, thigh and buttocks.

[0038] After processing and analyzing the human physiological data signal obtained by the data acquisition module 40, the main control module 20 generates a control signal and sends it to the counterpulsation control module 60. The counterpulsation control module 60 triggers the start of the forward sequential compression therapy according to the control signal. The preset counterpulsation pressure is 0.015MPa, and it is determined whether the D / S ratio of the finger pulse wave reaches 1.1. If not, it is gradually increased by 0.005MPa. When the D / S ratio reaches or exceeds 1.1, the positive and negative reciprocating sequential pressurization mode is activated, so that the counterpulsation bag assembly adopts the traditional counterpulsation mode within the preset 10 cardiac cycles to perform positive sequential pressurization on each bag from the distal end to the proximal end according to the preset time difference to increase the amount of blood returning to the heart; then, the counterpulsation bag assembly performs negative sequential pressurization on each bag from the proximal end to the distal end according to the preset time difference at a working pressure of 0.02MPa within the preset 5 cardiac cycles to increase the blood volume in the lower limbs and play a massage role; the positive sequential pressurization and negative sequential pressurization are repeated continuously until one treatment (45 minutes), changing from the traditional counterpulsation mode that aims to simply increase coronary artery blood perfusion to an action mode that mainly aims to increase the blood perfusion of the lower limbs and feet, thereby solving the problem of insufficient blood perfusion of the lower limbs and feet in diabetic foot.

[0039] By integrating the air source assembly 200 and various electrical modules into the main unit 100, the device can be miniaturized. At the same time, while meeting the requirements of each airbag for promoting lower limb hemodynamics, a smaller air pump 201 and a high-pressure air tank 202 are used to reduce the volume, weight, power consumption and heat generation of the main unit 100, making it suitable for daily use in households or community health centers.

[0040] In one embodiment of the present invention, the solenoid valve group includes a first solenoid valve 203a, a second solenoid valve 203b and a third solenoid valve 203c, and the first solenoid valve 203a, the second solenoid valve 203b and the third solenoid valve 203c are respectively connected to two tracheal interfaces 204, that is, one solenoid valve simultaneously controls the opening and closing of the two tracheal interfaces 204. The airbag includes two calf cuffs, two thigh cuffs and two buttocks cuffs, and the air inlet ends of the two calf cuffs are respectively connected to the two tracheal interfaces 204 corresponding to the first solenoid valve 203a through pipelines, the air inlet ends of the two thigh cuffs are respectively connected to the two tracheal interfaces 204 corresponding to the second solenoid valve 203 through pipelines, and the air inlet ends of the two buttocks cuffs are respectively connected to the two tracheal interfaces 204 corresponding to the third solenoid valve 203c through pipelines.

[0041] The positive sequential pressurization from the distal end to the proximal end controls the first solenoid valve 203a, the second solenoid valve 203b and the third solenoid valve 203c to open in sequence with a time difference of about 50ms, thereby increasing the diastolic pressure, driving the arterial blood back to the upper body, increasing the amount of venous blood returning to the heart, and improving the blood perfusion of important organs in the upper body such as the heart, brain, and kidneys; the negative sequential pressurization from the proximal end to the distal end controls the third solenoid valve 203c, the second solenoid valve 203b and the first solenoid valve 203a to open in sequence with a time difference of about 50ms, thereby increasing the blood perfusion of the lower limbs and feet; the present invention adopts a combinable bag sleeve, which can avoid the influence of the distal bag sleeve on the calf and foot ulcer areas of diabetic foot patients.

[0042] In one embodiment of the present invention, the shell 10 includes a bottom plate, a plurality of side walls protruding vertically from the bottom plate, and a panel 11 connecting the top ends of the plurality of side walls. The accommodating cavity is surrounded by the bottom plate, the plurality of side walls and the panel 11. The panel 11 is also provided with a touch screen 12 connected to the main control module 20, a control button 13 and a speaker 14.

[0043] Specifically, the touch screen 12 can display the patient's electrocardiogram signal, finger pulse signal, blood pressure signal and pulse signal in real time according to the acquired human physiological data signal; the control button 13 includes an air pressure increase key 131, an air pressure decrease key 132 and a switch and pause key 133. The air pressure increase key 131 and the air pressure decrease key 132 can realize manual adjustment of the pressure value of each bag cuff, and the switch and pause key 133 is used to control the switch of the host 100 and the pause function in an emergency; when the patient's heart rate is greater than 120 beats / minute, less than 40 beats / minute or the blood pressure is too high ≥170 / 100 mmHg during rehabilitation treatment, the main control module 20 issues an alarm through the speaker 14 and stops treatment.

[0044] In one embodiment of the present invention, Figure 3 As shown, the panel 11 is an inclined plate facing the front side of the host 100 , and a receiving groove 15 for accommodating the touch display screen 12 is formed in the panel 11 , and the rear end of the touch display screen 12 is rotatably installed in the receiving groove 15 via a rotating shaft 121 .

[0045] When the host 100 is placed horizontally, the angle between the panel 11 and the horizontal plane is 30 degrees, which is convenient for user operation; and the rotating shaft 121 extends in the left and right directions, and the display surface of the touch display screen 12 faces one side of the receiving groove 15, and the connecting line is arranged in the rotating shaft 121. Therefore, when the touch display screen 12 is not used and is folded and stored in the receiving groove 15, the display panel 11 of the touch display screen 12 can be well protected, thereby extending its service life and reducing the occupied space. Furthermore, a pivot shaft can be further provided, one end of which is vertically pivoted at the middle section of the rotating shaft 121, and the other end is pivoted to the touch display screen 12. The touch display screen 12 can rotate around the axis of the pivot shaft, and the pivot shaft can rotate around the axis of the rotating shaft 121. In this way, when the touch display screen 12 is in use, the touch display screen 12 can be flipped 180 degrees through the action of the rotating shaft 121 and the pivot shaft, so that its display surface faces upward for display work. When it is not needed, it can be flipped 180 degrees again so that its display surface faces downward for hidden protection.

[0046] In one embodiment of the present invention, a blood glucose detector 70 for detecting the patient's blood glucose is also provided in the accommodating cavity. The blood glucose detector 70 is fixed to the bottom of the panel 11 and connected to the main control module 20. A test paper entrance 16 is provided at the position of the panel 11 corresponding to the blood glucose detector.

[0047] In this way, the test paper coated with the patient's blood sample can be placed in the blood glucose detector 70 through the test paper inlet 16 for testing; and the data after the test can be fed back to the main control module 20, and the main control module then displays the data through the touch screen 12, so as to obtain the treatment effect visually.

[0048] Furthermore, a storage module 80 connected to the main control module 20 may be provided in the host 100, through which a patient management file may be established to record the patient's personal information, physiological data information, treatment plan, treatment effect, etc.

[0049] In one embodiment of the present invention, Figure 4 As shown, the power module 30 includes a rechargeable battery 31 arranged in the accommodating cavity and a charging interface 32 arranged on the rear side wall of the shell 10. Charging is performed through the charging interface 32 of the host 100, so that the rehabilitation therapy device of the present invention is suitable for use in an environment without power supply conditions and has a wide range of applications; a cooling fan 17 is also arranged on the rear side wall of the shell 10. Specifically, there are two cooling fans 17, one blowing toward the accommodating cavity of the shell 10, and the other blowing toward the outside of the shell 10, thereby forming convection to facilitate the extraction of heat in the host 100; of course, the two cooling fans 17 can also blow toward the outside of the shell 10 at the same time, and an air inlet is opened on the side wall of the shell 10.

[0050] In one embodiment of the present invention, the air source assembly 200 further includes an air filter 205 and a noise reducer 206. An air inlet 18 is provided on the front side wall of the housing 10. The air filter 205 is connected between the air inlet 18 and the air pump 201 through a pipeline. The air inlet 18 is a funnel-shaped structure and gradually increases from the outside to the inside, which is conducive to the air entering the air filter 205 to form a diffuse airflow and improve the cleaning and filtering effect. The noise reducer 206 is connected between the air pump 201 and the air storage tank 202 through a pipeline, thereby reducing the noise generated when the host 100 is running and increasing the comfort during treatment.

[0051] In one embodiment of the present invention, Figure 5 As shown, the extracorporeal counterpulsation rehabilitation therapy device of the embodiment of the present invention also includes a shock-absorbing base 300, the shock-absorbing base 300 includes a shock-absorbing support plate 301 and a plurality of shock-absorbing support feet 304 arranged at the bottom of the shock-absorbing support plate 301, and the main unit 100 is fixed on the shock-absorbing support plate 301; specifically, the shock-absorbing support plate 301 is a square plate-like structure, and its bottom surface is provided with four slide rails 302 extending from the four corners of the shock-absorbing support plate 301 toward the center direction respectively, and a reinforcing leg 303 is slidably provided in each slide rail 302, and a shock-absorbing support foot 304 is provided at the outer end of each reinforcing leg 303.

[0052] When in use, the four reinforcing legs 303 can be extended from their respective slide rails 302 for support. Combined with the four shock-absorbing support feet 304, the stability of the main unit 100 can be greatly increased and the impact of mechanical vibrations generated during the treatment process can be reduced. When not in use, the four reinforcing legs 303 can be stored and hidden in each slide rail 302 to make the structure more compact and reduce space occupancy.

[0053] The present invention also provides a control method for an external counterpulsation rehabilitation therapeutic apparatus, such as Figure 6 As shown, the following steps are included:

[0054] S1. Acquire a patient's physiological data signal wirelessly or wired, where the physiological data signal includes the patient's electrocardiogram signal, finger pulse signal, blood pressure signal, and pulse signal.

[0055] Specifically, step S1 also includes establishing a personalized management file for the patient, recording the acquired human physiological data signals, and inputting the patient's personal information and treatment plan through the touch screen 12; according to the clinical classification of diabetic foot and the specific situation of the patient's lower limb ulcer, deciding whether to wear a calf cuff, that is, choosing to adopt a secondary or tertiary counterpulsation mode treatment plan.

[0056] S2. Based on the Q, R, and S waves in the real-time ECG signal, the R wave is used to trigger the initiation of forward counterpulsation therapy, and the preset counterpulsation pressure is 0.015 MPa; that is, the three groups of airbags of the counterpulsation airbag assembly are pressurized sequentially in the forward direction to a preset pressure value of 0.015 MPa, and the D / S ratio of the diastolic wave peak to the systolic wave peak is calculated based on the acquired human physiological data signal. When D / S ≥ 1.1, it is considered that the counterpulsation effect can be achieved; if D / S < 1.1, the pressure value of each airbag is gradually increased by 0.005 MPa until D / S ≥ 1.1, and the maximum counterpulsation pressure does not exceed 0.035 MPa.

[0057] S3. When the D / S ratio of the diastolic peak to the systolic peak is reached, a control signal is generated and sent to the counterpulsation control module 60. The counterpulsation control module 60 triggers the positive sequential pressurization therapy according to the control signal. The preset counterpulsation pressure is 0.015MPa, and it is determined whether the D / S ratio of the finger pulse wave reaches 1.1. If it cannot reach it, it is gradually increased by 0.005MPa. When the D / S ratio reaches or exceeds 1.1, the positive and negative reciprocating sequential pressurization mode is started, so that the counterpulsation airbag assembly adopts the traditional counterpulsation mode within the preset 10 cardiac cycles to perform positive sequential pressurization from the distal end to the proximal end of each airbag according to the preset time difference to increase the amount of blood returning to the heart; then the counterpulsation airbag assembly is made to perform negative sequential pressurization from the proximal end to the distal end of each airbag according to the preset time difference within the preset 5 cardiac cycles at a working pressure of 0.02MPa to increase the blood volume of the lower limbs.

[0058] During specific rehabilitation treatment, step S3 is repeated until a total of 45 minutes of rehabilitation treatment is completed; during the rehabilitation treatment, when the patient's heart rate is greater than 120 beats / minute, less than 40 beats / minute, or the blood pressure is too high ≥170 / 100 mmHg, the host 100 alarms through the speaker 14 and forces the treatment to stop; of course, during the specific treatment process, if the patient has any discomfort, the switch and pause button 133 can also be used to force the patient to stop and exit the treatment.

[0059] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
