Description

Technical Field

[0001] This invention relates to the field of venous thrombosis technology, and more specifically, to a wearable anti-venous thrombosis pressure pump detection system and its control method. Background Technology

[0002] Venous thrombosis is a common clinical disease, with deep vein thrombosis (DVT) being the most serious, particularly in the lower extremities. Slow blood flow, hypercoagulability, and changes in the venous intima are three important factors contributing to venous thrombosis. The main dangers of venous thrombosis are: 1) Deep vein thrombosis can cause swelling, pain, and dysfunction in the affected limb, and in severe cases, can lead to venous gangrene. 2) Pulmonary embolism is the most dangerous complication of venous thrombosis, potentially leading to severe symptoms and even sudden death. 3) Venous thrombosis can also trigger post-thrombotic syndrome, which can cause long-term lower extremity edema, skin pigmentation, and ulcers, severely impacting quality of life.

[0003] Existing technologies typically utilize multi-chambered airbags of different types, depending on the application site (upper limbs, lower limbs, waist, back, etc.). Through sequential and repeated inflation and deflation, pressure is applied to the limbs and tissues in a cyclical manner, providing uniform and orderly compression from the distal to the proximal end of the limb. This results in a large-area compression and massage effect, increasing venous blood flow in patients at risk of venous thrombosis, significantly improving blood flow velocity, reducing blood stasis, and thus preventing deep vein thrombosis and pulmonary embolism. Through this passive and uniform massage, the accelerated blood circulation promotes the absorption of metabolic waste products, inflammatory factors, and pain-causing factors in the blood, preventing muscle atrophy and fibrosis, increasing oxygen levels in the limbs, and helping to address diseases caused by circulatory disorders (such as femoral head necrosis).

[0004] Existing wearable antithrombotic pressure pump monitoring systems do not have pressure detection devices. This means that many patients cannot know whether the output pressure of the pressure pump they are using exceeds the safe value. In clinical practice, the patients who need to use wearable antithrombotic pressure pumps are mostly elderly people with disabilities or dementia who are bedridden for a long time. These patients usually cannot actively report their own feelings, which may lead to safety hazards such as limb or tissue damage when using the pressure pump. Summary of the Invention

Whenever the working pressure of the pressure pump assembly is outside the predetermined working pressure range, the detection frequency of the pressure sensor will increase once until the detection frequency of the pressure sensor is adjusted to the maximum detection frequency.

[0015] Optionally: Set a minimum detection frequency for a pressure sensor. When the pressure sensor detects five consecutive times that the working pressure of the pressure pump assembly is within a predetermined working pressure range, reduce the detection frequency of the pressure sensor until the detection frequency of the pressure sensor is reduced to the minimum detection frequency.

[0029] Example: See Figures 1 to 8This invention discloses a wearable anti-thrombotic pressure pump detection system, comprising a limb sleeve 100, a blood flow detector 200, a vascular injury detector 300, a pressure pump assembly 400, a pressure sensor, and a processor 500. The blood flow detector 200, vascular injury detector 300, pressure pump assembly 400, pressure sensor, and processor 500 are all mounted on the limb sleeve 100, which can be easily worn on the patient's body. The limb sleeve 100 can be designed with Velcro, buttons, pins, or felt zippers. The blood flow detector 200 is used to detect the blood flow velocity in the patient's body, and the vascular injury detector 300 is used to detect whether there is damage to the blood vessels in the patient's body. The pressure sensor is used to detect the working pressure output by the pressure pump assembly 400, and the processor 500 can automatically adjust the working pressure output by the pressure pump assembly 400 according to initial settings.

[0030] The wearable antithrombotic pressure pump detection system disclosed in this embodiment utilizes a pressure sensor to detect the working pressure output of the pressure pump assembly 400 in real time. When the working pressure output of the pressure pump assembly 400 exceeds the safe value, the processor 500 can quickly give the pressure pump assembly 400 an adjustment command, thereby ensuring that the working pressure output of the pressure pump assembly 400 is continuously kept within the safe range, thereby reducing the safety hazards for patients during use.

[0031] The blood flow detector 200 and the vascular injury detector 300 are already mature technologies. This embodiment does not propose any improvements to the blood flow detector 200 and the vascular injury detector 300 themselves. Therefore, this embodiment will not further explain the structure and working principle of the blood flow detector 200 and the vascular injury detector 300. The blood flow detector 200 and the vascular injury detector 300 can be purchased and used directly on the market.

[0032] A pressure sensor is a device that senses pressure signals and converts them into a usable electrical output signal according to a certain rule. Pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. Based on different types of pressure being measured, pressure sensors can be classified into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. Pressure sensors are one of the most commonly used sensors in industrial practice, widely applied in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemicals, oil wells, power, shipbuilding, machine tools, pipelines, and many other industries. Pressure sensors are a mature, existing technology and can be purchased and used directly on the market.

[0033] It is understood that the processor 500 includes at least an acquisition circuit, a comparison circuit, and a control circuit connected in sequence. The acquisition circuit is signal-connected to the pressure sensor and is used to acquire the current value of the pressure pump assembly 400 at different pressures. The comparison circuit receives the current from the acquisition circuit and outputs different comparison currents based on the difference between the current from the pressure sensor and the current that may be generated at a preset pressure. The control circuit receives the comparison current from the comparison circuit and outputs different control currents based on the different comparison currents. It should be noted that the comparison circuit outputs the comparison current based on the difference in sensor currents, and the control circuit outputs the control current based on the comparison current, both satisfying a pre-stored mapping relationship, which can be determined by a storage component or circuit structure.

[0034] See Figures 2 to 6 The pressure pump assembly 400 includes a base 410, a drive motor, a drive disc 420, a control block 430, a control rod 440, a connecting block 450, a piston cylinder 470, and a piston rod 460.

[0035] The drive disk 420 is rotatably connected to the base 410, and the drive motor is driveably connected to the drive disk 420, driving the drive disk 420 to rotate. In this embodiment, the drive motor drives the drive disk 420 to rotate continuously at the same speed.

[0036] A lever 421 is provided on the drive disc 420, and the lever 421 is eccentrically positioned. A slot 441 is provided in the middle of the control lever 440 (not specifically the center position, but only distinguished by its end). The slot 441 cooperates with the lever 421 so that the control lever 440 can swing back and forth when the drive disc 420 rotates.

[0037] In this embodiment, the cross-section of the lever 421 can be set to be circular so that the lever 421 can smoothly drive the control lever 440 to swing when the drive disk 420 rotates. Of course, making the cross-section of the lever 421 circular is only one implementation method in this embodiment. In other implementation methods, the lever 421 can be set to a distance, and then the lever 421 can be rotated in conjunction with the drive disk 420 to achieve smooth swinging of the control lever 440.

[0038] The control block 430 is slidably connected to the base 410, and the direction of movement of the control block 430 is perpendicular to the rotation axis of the drive disk 420. A cylinder 490 can be installed between the control block 430 and the base 410. The cylinder 490 is mounted on the base 410, and its output end is connected to the control block 430. The position of the control block 430 is controlled by the cylinder 490, making operation more convenient and precise. The first end of the control lever 440 is rotatably connected to the control block 430. The control block 430 is used to control the swing amplitude of the control lever 440. When the control block 430 moves closer to the drive disk 420, the swing angle of the control lever 440 increases, and the distance the second end of the control lever 440 moves horizontally also increases. When the control block 430 moves away from the drive disk 420, the swing angle of the control lever 440 decreases, and the distance the second end of the control lever 440 moves horizontally also decreases.

[0039] The connecting block 450 is slidably connected to the base 410. The sliding direction of the connecting block 450 is perpendicular to the rotation axis of the drive disk 420, and the sliding direction of the connecting block 450 is perpendicular to the sliding direction of the control block 430. The second end of the control rod 440 is slidably engaged with the connecting block 450, and the control rod 440 can drive the connecting block 450 to move back and forth.

[0040] The piston cylinder 470 is mounted on the base 410, and a one-way valve 481 and an air port are provided on the piston cylinder 470. The piston rod 460 is connected to the connecting block 450, and the piston rod 460 and the piston cylinder 470 are in sliding engagement. When the connecting block 450 drives the piston rod 460 to move back and forth, the piston cylinder 470 can be filled and vented, thereby achieving the purpose of outputting working pressure.

[0041] The slot 441 is arranged along the length of the control rod 440. The width of the slot 441 is equal to the diameter of the lever 421, and the length of the slot 441 is greater than the diameter of the lever 421. When the control block 430 drives the control rod 440 to move up and down, the lever 421 is kept within the slot 441, thus ensuring that the drive disc 420 can continuously drive the control rod 440 to swing when it rotates.

[0042] A sliding groove 451 is provided on the connecting block 450, and the sliding groove 451 is set along the height direction of the connecting block 450. A locking block is provided at the second end of the control rod 440, and the locking block slides and engages with the sliding groove 451, and the cross-section of the locking block is circular. When the control rod 440 swings around its first end, the height of its second end will change first. When the control block 430 drives the control rod 440 to move up and down, the second end of the control rod 440 will also move up and down. Therefore, after providing the strip-shaped sliding groove 451 on the connecting block 450, the control rod 440 and the connecting block 450 can better cooperate, ensuring that the connecting block 450 only swings back and forth in the horizontal direction and does not move in the vertical direction, thereby ensuring the stability of the piston rod 460.

[0043] In some embodiments of this example, two control levers 440 can be configured, and correspondingly, two levers 421 on the drive disk 420 are also configured. The two levers 421 are located on both sides of the drive disk 420, and the connecting line of the two levers 421 passes through the center of the drive disk 420. The two control levers 440 are configured in a one-to-one correspondence with the two levers 421. In addition, two connecting blocks 450, piston rods 460, and piston cylinders 470 are also configured. The second end of each control lever 440 is sequentially connected to the connecting block 450, piston rod 460, and piston cylinder 470. The first ends of the two control levers 440 are connected to the same control block 430 to facilitate synchronous control of the two control levers 440.

[0044] The two piston cylinders 470 are connected by a connecting pipe 480 to pressurize the same position. By setting two control levers 440 and related structures, and symmetrically arranging two levers 421 around the center of the drive disc 420, it can be ensured that when one piston cylinder 470 is drawing in air, the other piston cylinder 470 is expelling air. The two piston cylinders 470 work alternately to continuously and intermittently output gas, thereby ensuring that the working pressure output by the pressure pump assembly 400 remains stable.

[0045] When the working pressure output of the pressure pump assembly 400 needs to be adjusted, the control block 430 can be moved simply by controlling the linear control structure such as the cylinder 490. When the control block 430 moves closer to the drive plate 420, the horizontal swing amplitude of the second end of the control rod 440 increases. At this time, the stroke of the piston rod 460 increases, and more gas can be output in one intake and exhaust process, thereby increasing the working pressure output of the pressure pump assembly 400. Conversely, when the control block 430 moves away from the drive plate 420, the horizontal swing amplitude of the second end of the control rod 440 decreases. At this time, the stroke of the piston rod 460 decreases, and less gas is output in one intake and exhaust process, thereby decreasing the working pressure output of the pressure pump assembly 400.

[0046] In some embodiments of this example, two drive disks 420 are provided. Since the control lever 440 sweeps across the entire range of the drive disk 420 when it drives the control lever 440 to swing, using only one drive disk 420 may cause inconvenience in installing the drive motor. By providing two drive disks 420 and placing the drive motor between them, the drive motor can drive the two drive disks 420 to rotate synchronously without affecting the swing of the control lever 440.

[0047] See Figure 2 , Figure 7 and Figure 8 In some embodiments of this example, a support frame 491 is provided at the bottom of the drive motor 490, and the support frame 491 is arranged parallel to the piston rod 460. A first stop 411 and a second stop 412 are provided on the base 410, and the first stop 411 and the second stop 412 are spaced apart along the height direction of the base 410.

[0048] The wearable antithrombotic pressure pump detection system also includes a control component 600, which includes a transmission rod 610, a guide plate 620, and an elastic element 630. The transmission rod 610 is connected to the drive motor 490 and is parallel to the support frame 491. The guide plate 620 is connected to the end of the transmission rod 610 facing away from the drive motor 490. The guide plate 620 is elliptical in shape and rotatably engages with the base 410. The guide plate 620 can move up and down relative to the base 410. The guide plate 620 is located between the first stop 411 and the second stop 412. The support frame 491 is slidably connected to the guide plate 620. The two ends of the elastic element 630 act on the guide plate 620 and the first stop 411, respectively. The elastic element 630 drives the bottom of the guide plate 620 to abut against the second stop 412.

[0049] When the transmission rod 610 rotates, it drives the guide plate 620 to rotate synchronously. Since the guide plate 620 is elliptical and the elastic force of the elastic element 630 will always keep the guide plate 620 in contact with the second stop 412, the axis of the guide plate 620 will move up and down when it rotates. This causes the transmission rod 610, the support frame 491, and the drive motor 490 and drive plate 420 on the support frame 491 to move up and down reciprocally.

[0050] When the drive disc 420 rotates, due to the eccentric setting of the lever 421 and the drive disc 420, the moving distance of the lever 421 in the direction parallel to the piston rod 460 is different when the drive disc 420 rotates by the same angle. This results in different moving distances of the connecting block 450 when the drive disc 420 rotates by the same angle, which may lead to unstable pressure output from the connecting pipe 480. Furthermore, when the drive disc 420 moves up and down, it also changes the moving distance of the lever 421 in the direction parallel to the piston rod 460 when the drive disc 420 rotates by the same angle. By reasonably setting the ratio of the major and minor axes of the guide disc 620 and the angular coordination between the guide disc 620 and the control rod 440, the up-and-down swing of the drive disc 420 can offset the change in the moving distance of the lever 421 in the direction parallel to the piston rod 460, thus ensuring that the connecting block 450 moves the same distance when the drive disc 420 rotates by the same angle, thereby achieving stable pressure output from the connecting pipe 480.

[0051] In some embodiments of this example, the guide disk 620 is provided with an annular guide groove 621, and the support frame 491 is inserted into the guide groove 621, with the support frame 491 slidingly engaged with the guide groove 621. When the transmission rod 610 drives the guide disk 620 to rotate, the support frame 491 slides within the guide groove 621; when the guide disk 620 causes the transmission rod 610 to move up and down, the support frame 491 moves along with it, and drives the drive connection and the drive disk 420 to move up and down together.

[0052] In one embodiment, the output end of the drive motor 490 is provided with a first bevel gear 492 and a second bevel gear 493, the drive disk 420 is provided with a third bevel gear 422, which meshes with the first bevel gear 492, and the transmission rod 610 is provided with a fourth bevel gear 611, which meshes with the second bevel gear 493. When the drive motor 490 is working, it can drive the first bevel gear 492 and the second bevel gear 493 to rotate synchronously, thereby driving the drive disk 420 and the transmission rod 610 to rotate together.

[0053] Referring to 9, this embodiment of the invention also discloses a control method for a wearable antithrombotic pressure pump detection system, which includes the following steps: Step 1: Put the limb sleeve on the patient, set the predetermined working pressure range of the pressure pump assembly, and then start the pressure pump assembly to work; Step 2: Use a pressure sensor to detect the working pressure of the pressure pump assembly and set the detection frequency of the pressure sensor. When the working pressure of the pressure pump assembly is outside the predetermined working pressure range, adjust the working pressure of the pressure pump assembly.

[0054] The specific methods for pressure regulation are as follows: First, set an initial detection frequency, a maximum detection frequency for one pressure sensor, and a minimum detection frequency for another pressure sensor. Then, set a pressure increase value and a pressure decrease value (the pressure increase and decrease can be adjusted by adjusting the position of a control block; controlling the movement distance of this control block controls the magnitude of the pressure increase or decrease). Finally, set a frequency decrease value and a frequency increase value.

[0055] When the working pressure of the pressure pump assembly is detected to be lower than the predetermined minimum working pressure, the working pressure of the pressure pump assembly is increased, and the detection frequency of the pressure sensor is increased. When the working pressure of the pressure pump assembly is detected to be higher than the predetermined maximum working pressure, the working pressure of the pressure pump assembly is decreased, and the detection frequency of the pressure sensor is increased.

[0056] Whenever the working pressure of the pressure pump assembly is outside the predetermined working pressure range, the detection frequency of the pressure sensor will increase once, until the detection frequency of the pressure sensor is adjusted to the maximum detection frequency.

[0057] When the pressure sensor detects that the working pressure of the pressure pump assembly is within the predetermined working pressure range five times in a row, the detection frequency of the pressure sensor is reduced until the detection frequency of the pressure sensor is reduced to the minimum detection frequency.

[0058] Based on the above settings, the control method disclosed in this embodiment can be implemented in the following manner: Set the initial detection frequency =60 seconds / time, maximum detection frequency =30 seconds / time, minimum detection frequency =90 seconds / time, set frequency decrease value =5 seconds / time, frequency increases value =5 seconds / time.

[0059] The wearable anti-thrombotic pressure pump detection system starts working. When it detects that the operating pressure of the pressure pump component is lower than the predetermined minimum operating pressure, it instructs the pressure pump component to increase its operating pressure and simultaneously increases the detection frequency of the pressure sensor. At this point, the detection frequency is adjusted to... = - =55 seconds / time; When the operating pressure of the pressure pump assembly is detected to be greater than the predetermined maximum operating pressure, the pressure pump assembly is instructed to reduce its operating pressure, while the detection frequency of the pressure sensor is increased. At this time, the detection frequency is adjusted to... = - =55 seconds / time.

[0060] Each time the operating pressure of the pressure pump assembly falls outside the predetermined operating pressure range, the detection frequency of the pressure sensor increases by one step, until the detection frequency of the pressure sensor is adjusted to the maximum detection frequency. =30 seconds / time.

[0061] When the pressure sensor detects that the operating pressure of the pressure pump assembly is within the predetermined operating pressure range five times consecutively, the detection frequency of the pressure sensor is reduced, and the detection frequency is adjusted to... = + =65 seconds / time, until the pressure sensor's detection frequency is reduced to the minimum detection frequency. =90 seconds / time.

[0062] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
