Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for preventing and treating VTE venous thrombosis. Background Art

[0002] VTE, or venous thromboembolism, refers to abnormal blood coagulation in the veins, which completely or partially blocks the blood vessels. It is a venous reflux disorder. VTE includes deep vein thrombosis (DVT) and pulmonary embolism (PE). Deep vein thrombosis often occurs in the deep veins of the lower limbs, such as the iliac vein, femoral vein, and popliteal vein. After the thrombus breaks off, it may move with the blood flow to the pulmonary artery, causing pulmonary embolism, which is a potentially life-threatening disease.

[0003] After undergoing major orthopedic, abdominal, pelvic and other surgeries, patients are bedridden, which slows blood flow and causes vascular endothelial damage and braking factors; or patients suffer from acute and severe diseases such as acute myocardial infarction, heart failure, respiratory failure, and stroke, with limited mobility and hypercoagulable blood; patients with malignant tumors, some tumor cells release procoagulant substances, thereby increasing the risk of thrombosis; and pregnant and postpartum women, especially pregnant women who are bedridden after cesarean section, are prone to thrombosis due to hypercoagulable blood. Therefore, doctors will decide whether to use a VTE venous thrombosis prevention device based on the specific conditions of different patients, such as the underlying disease, type of surgery, bed rest time, and VTE risk assessment results.

[0004] For VTE venous thrombosis prevention devices, venous foot pumps are usually used to periodically inflate and pressurize the soles of the feet, causing the plantar venous plexus to be squeezed, thereby increasing the venous return rate, reducing blood congestion in the lower limb veins, and reducing the risk of venous thrombosis. However, most existing venous foot pumps apply pressure to both feet at the same time, or perform reciprocating pressure operations on both feet synchronously in a fixed order and time interval. In this way, each foot cannot be given a separate and intermittent rest opportunity, which may cause patients to experience more obvious fatigue or discomfort when using it;

[0005] Moreover, due to the differences in foot size, shape and sensitivity among different patients, existing venous foot pumps are difficult to better adapt to the foot conditions of different patients, which can easily cause uneven pressure distribution. Some patients may even feel uncomfortable when using them, resulting in less than ideal prevention effects.

[0006] In view of this, the present invention provides a device for preventing and treating VTE venous thrombosis. Summary of the invention

[0007] The purpose of the present invention is to provide a VTE venous thrombosis prevention and treatment device to solve the problems raised in the above background technology.

[0014] As a further improvement of the present technical solution, the airbag includes a plantar airbag and a dorsal airbag, the plantar airbag is fixedly connected to the inside of the groove in the center of the tread plate, two hoses are fixedly connected between the outer walls on one side of the two plantar airbags, the outer wall on the other side of the plantar airbag is fixedly connected to the dorsal airbag, the dorsal airbag surrounds the top of the plantar airbag, and is movably connected to the outer wall where it penetrates into the tread plate with a clamping assembly.

[0015] As a further improvement of the present technical solution, the inner wall of the airbag is made of elastic rubber material, and the outer wall of the airbag is made of thermal insulation cotton material.

[0016] As a further improvement of the present technical solution, the clamping assembly includes two sliding rods, both of which are movably connected inside the pedal plate, one end of the two sliding rods is respectively fixedly connected with a convex plate and a concave plate, the convex plate and the concave plate are movably connected inside the groove of the pedal plate, and the sliding rod passes through the outer wall of the pedal plate and is movably connected with a nut.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the VTE venous thrombosis prevention and treatment device, one of the pedals is driven to rise by the cylinder, so that the inflatable component inside the pedal is evacuated, and the air pressure of the inflatable component inside the other pedal is absorbed into the inside of the pedal; at the same time, the cylinder drives the other pedal to descend, so that the air pressure of the inflatable component inside the pedal is squeezed, and then the air pressure of the inflatable component inside the pedal is squeezed into the inflatable component of the above-mentioned pedal; in this way, it is convenient to inflate and pressurize the foot between one of the pedals and the inflatable component, so that the plantar venous plexus is squeezed, and this pressure is transmitted to the deep veins of the calf, forcing the blood in the veins to flow back.

[0019] 2. In the VTE venous thrombosis prevention and treatment device, when the pedal at the top descends under the action of the cylinder, the pressure of the inflatable component inside the pedal is transmitted to the inflatable component inside the other pedal. When the pressure of the inflatable component inside the pedal is released, the vein is refilled. This repeated cycle simulates the "blood pumping" function of muscle contraction on the vein during normal walking or activities, increases the venous return rate, reduces the blood congestion in the lower limb veins, and reduces the risk of venous thrombosis; and, in the process of alternating reciprocating motion of the inflatable components in the two pedals, it simulates the process of the human body's natural walking when the two feet alternately push the blood back, which can more effectively promote the flow of blood from the lower limb veins to the heart and reduce blood congestion.

[0020] 3. In the VTE venous thrombosis prevention and treatment device, after placing the foot between the inflatable component and the pedal, let the inflatable component surround the patient's foot and pass through the groove on one side of the pedal, and then use the clamping component to clamp and fix the inflatable component; this makes it easy to adjust the tightness of the inflatable component according to the size, shape and sensitivity of the feet of different patients; at the same time, when the inflatable component is clamped, the size of the air pressure space inside the inflatable component can also be adjusted, so as to facilitate the precise adjustment of the inflation space according to the patient's specific condition and treatment needs, so as to achieve more precise pressure control, optimize the effect of promoting venous blood return, avoid excessive or insufficient local pressure due to inappropriate inflation space, reduce the patient's discomfort during use, and enhance the patient's compliance with treatment.

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example

[0038] See also Figure 1-Figure 9 As shown, the purpose of this embodiment is to provide a VTE venous thrombosis prevention and treatment device, including a base 1, a support 11 is movably connected to the top of the base 1, a support assembly 12 is movably connected between the support 11 and the base 1, and two pedals 2 are movably connected to the top of the base 1;

[0039] Two cylinders 21 are fixedly connected to the bottom of the pedal board 2, and the cylinders 21 are fixedly connected to the inside of the support 11. An inflatable component 22 is fixedly connected between the two pedal boards 2, and a clamping component 23 is movably connected inside the pedal board 2, and the clamping component 23 is movably connected between the inner wall and the outer wall of the inflatable component 22;

[0040] The inflatable component 22 is used to periodically inflate and pressurize the patient's foot while simulating a walking state, and the clamping component 23 is used to adjust the size of the inflatable component 22 and adjust the air pressure space inside the inflatable component 22;

[0041] The improvement of this embodiment is that after placing the foot between the inflatable component 22 and the pedal board 2, the inflatable component 22 is allowed to surround the patient's foot and pass through the groove on one side of the pedal board 2, and then the inflatable component 22 that passes through is clamped and fixed by the clamping component 23; this makes it easy to adjust the tightness of the inflatable component 22 according to the size, shape and sensitivity of the feet of different patients; at the same time, when the inflatable component 22 is clamped, the size of the air pressure space inside the inflatable component 22 can also be adjusted, so as to facilitate the precise adjustment of the inflatable space according to the patient's specific condition and treatment needs, so as to achieve more accurate pressure control, optimize the effect of promoting venous blood return, avoid the situation where the local pressure is too large or too small due to inappropriate inflatable space, reduce the patient's discomfort during use, and enhance the patient's compliance with treatment;

[0042] The cylinder 21 drives one of the pedals 2 to rise, causing the inflatable component 22 inside the pedal 2 to be evacuated, and the air pressure of the inflatable component 22 inside the other pedal 2 is absorbed into itself; at the same time, the cylinder 21 drives the other pedal 2 to descend, causing the air pressure of the inflatable component 22 inside the pedal 2 to be squeezed, and then the air pressure of the inflatable component 22 inside the pedal 2 is squeezed into the inflatable component 22 of the above-mentioned one pedal 2; in this way, it is convenient to inflate and pressurize the foot between one of the pedals 2 and the inflatable component 22, so that the plantar venous plexus is squeezed, and this pressure is transmitted to the deep veins of the calf, forcing the blood in the veins to flow back.

[0043] When the pedal 2 at the top descends under the action of the cylinder 21, the pressure of the inflatable component 22 inside the pedal 2 is transmitted to the inflatable component 22 inside the other pedal 2. When the pressure of the inflatable component 22 inside the pedal 2 is released, the veins are refilled. This repeated cycle simulates the "blood pumping" function of muscle contraction on the veins during normal walking or activities, improves the venous return speed, reduces the blood congestion in the lower limb veins, and reduces the risk of venous thrombosis; and, in the process of the inflatable components 22 in the two pedals 2 alternately reciprocating, it simulates the process of the human body's natural walking when the two feet alternately push the blood back, which can more effectively promote the flow of blood from the lower limb veins to the heart and reduce blood congestion.

[0044] First, the specific structure of the support assembly 12 is disclosed. The support assembly 12 includes two support blocks 120, and the support block 120 is fixedly connected to the top of the base 1. A rotating rod 121 is fixedly connected between the two support blocks 120, and the rotating rod 121 is movably connected to the inside of the support 11. A telescopic rod 122 is movably connected to the inside of the base 1, and the telescopic rod 122 is movably connected to the bottom of the support 11; by pulling the support 11, it is rotated between the outer wall of the rotating rod 121 and the support block 120, so that the support 11 is separated from the base 1, and the telescopic rod 122 inside the base 1 can be pulled out, and by adjusting the length of the telescopic rod 122, the end of the telescopic rod 122 can be supported in the circular holes at different positions on the bottom of the support 11, so as to facilitate the adjustment of the support angle of the support 11, so that the two pedals 2 can be perpendicular or parallel to the ground to meet the use needs of patients in different states.

[0045] The telescopic rod 122 includes a thick rod 1220, and two protruding rods 1223 are fixedly connected to the outer wall of the thick rod 1220 near one end thereof. The thick rod 1220 and the protruding rod 1223 are both movably connected to the inside of the base 1. A screw 1222 is fixedly connected to the inside of the thick rod 1220, and a thin rod 1221 is movably connected between the outer wall of the screw 1222 and the inner wall of the thick rod 1220. The thin rod 1221 is movably connected to the inside of the spherical groove at the bottom of the support 11; by pulling the thin rod 1221 to drive the thick rod 1220 to move, the thick rod 1220 can be moved. The rod 1220 is pulled out upward from the inside of the base 1, and the protruding rod 1223 rotates inside the base 1 to adjust the angle between the thin rod 1221 and the thick rod 1220. By rotating the thin rod 1221, it is rotated on the outer wall of the screw rod 1222, so that the thin rod 1221 is telescopically adjusted inside the thick rod 1220 along the outer wall of the screw rod 1222, and then the length between the thick rod 1220 and the thin rod 1221 is adjusted, so that the support 11 can be supported at any height and any angle.

[0046] Secondly, the specific structure of the inflatable component 22 is disclosed. The inflatable component 22 includes an airbag 220, which is fixedly connected to the inside of the groove in the center of the pedal 2. Two hoses 221 are fixedly connected between the two airbags 220. A plurality of air tubes 222 are fixedly connected to the outer wall of the other side of the airbag 220. An air cylinder 223 is fixedly connected between the ends of the plurality of air tubes 222 on the same airbag 220 and the inside of the pedal 2. A piston 224 is movably connected inside the air cylinder 223. A support rod 225 is fixedly connected between the end of the piston 224 and the top of the support 11. Through the cylinder 2 1 drives one of the pedals 2 to move upward, while the other pedal 2 moves downward, causing the two air cylinders 223 to move upward and downward respectively; in this way, the air cylinder 223 moving upward acts on the outer wall of the piston 224 inside it, causing the piston 224 to generate a downward suction force inside the upward air cylinder 223, thereby absorbing the air pressure inside the air bag 220 in the other pedal 2 into the air bag 220 of the pedal 2 through the hose 221, causing the air bag 220 inside the upward pedal 2 to expand, thereby squeezing the veins of the foot of the patient on the upward pedal 2;

[0047] The downwardly moving pedal 2 drives the air cylinder 223 to move downward together, so that the piston 224 inside the air cylinder 223 moves upward under the relative force, wherein the support rod 225 supports the piston 224, and the downwardly moving air cylinder 223 is squeezed by the piston 224, so that the gas inside the air cylinder 223 is squeezed into the air bag 220 through the trachea 222, and at the same time, the gas inside the downward air bag 220 is input into the upward air bag 220 through the hose 221, so as to accelerate the expansion speed of the upward air bag 220; at the same time, the gas inside the air bag 220 inside the downward pedal 2 is contracted, so that the foot veins of the patient on the downward pedal 2 are refilled, so as to realize venous return;

[0048] During the single up and down reciprocating motion of the pedal 2, the "blood pumping" function of the muscle contraction on the vein during normal walking or activities is simulated, which increases the venous return rate, reduces the blood congestion in the lower limb veins, and reduces the risk of venous thrombosis. In the up and down alternating motion of the two pedals 2, the process of the human body's natural walking with both feet alternately pushing the blood back can be simulated, which can more effectively promote the flow of blood in the lower limb veins to the heart and reduce blood congestion. In addition, in the alternating motion state of the feet, the patient's leg muscles can also be exercised to prevent the patient from experiencing muscle atrophy.

[0049] The airbag 220 includes a plantar airbag 2201 and a dorsal airbag 2202. The plantar airbag 2201 is fixedly connected to the groove in the center of the pedal board 2. Two hoses 221 are fixedly connected between the outer walls of one side of the two plantar airbags 2201. The outer wall of the other side of the plantar airbag 2201 is fixedly connected to the dorsal airbag 2202. The dorsal airbag 2202 surrounds the top of the plantar airbag 2201 and is movably connected to the outer wall of the pedal board 2. The plantar airbag 2201 is filled or deflated to squeeze the veins on the sole of the patient or promote reflux. The dorsal airbag 2202 is filled or deflated to squeeze the veins on the dorsum of the patient's foot or promote reflux. At the same time, the dorsal airbag 2202 is wrapped around the top of the plantar airbag 2201. The patient's foot is fixed between the dorsal airbag 2202 and the plantar airbag 2201, so that when the internal air pressure of the dorsal airbag 2202 and the plantar airbag 2201 is filled or deflated, the venous compression or reflux of the patient's dorsum and sole is performed simultaneously; and when the wrapping position and size of the dorsal airbag 2202 are fixed, the internal air pressure space of the dorsal airbag 2202 can also be squeezed and adjusted, so that the inflation space can be accurately adjusted according to the patient's specific condition and treatment needs, thereby achieving more precise pressure control, optimizing the effect of promoting venous blood return, avoiding the situation where the local pressure is too high or too low due to inappropriate inflation space, reducing the discomfort of the patient during use, and enhancing the patient's compliance with treatment.

[0050] In addition, the inner wall of the airbag 220 is made of elastic rubber, and the outer wall of the airbag 220 is made of thermal insulation cotton. With the elasticity and deformation ability of the elastic rubber structure of the inner wall of the airbag 220, it can better fit the foot shape and size of different patients, provide uniform pressure distribution, and improve the treatment effect. At the same time, the elastic rubber has good wear resistance and fatigue resistance, and can withstand multiple inflation and deflation cycles, thereby extending the service life of the airbag 220. During the inflation and pressurization process, the elastic rubber can play a certain buffering role, making the pressure change relatively gentle, reducing the sudden impact on the blood vessels and tissues of the foot, and can maintain the air pressure inside the airbag 220 stable, reduce gas leakage, and ensure the accurate transmission of pressure and the stability of treatment.

[0051] At the same time, the thermal insulation material used for the outer wall of the airbag 220 is generally an airtight polyurethane coated fabric, which can achieve the dual effects of sealing and thermal insulation by applying a polyurethane coating on the surface of the fabric, thereby helping to maintain a stable temperature of the foot, especially during the long-term use of the venous foot pump. It can prevent the foot from losing too much heat due to being in the external environment for a long time, thereby maintaining good blood circulation; in addition, the thermal insulation material can also keep the foot warm and promote blood vessel dilation, further optimizing the venous foot pump's effect on promoting blood return and improving the effectiveness of preventing and treating venous thrombosis.

[0052] Finally, the specific structure of the clamping assembly 23 is disclosed. The clamping assembly 23 includes two slide bars 232, and the two slide bars 232 are movably connected to the inside of the pedal board 2. One end of the two slide bars 232 is fixedly connected to a convex plate 231 and a concave plate 230 respectively. The convex plate 231 and the concave plate 230 are movably connected to the inside of the groove of the pedal board 2. The slide bar 232 passes through the outer wall of the pedal board 2 and is movably connected to a nut 233. The two slide bars 232 slide inside the pedal board 2 to adjust the distance between the convex plate 231 and the concave plate 230. When the instep is inflated, the convex plate 231 and the concave plate 230 are adjusted. When the bag 2202 passes through between the convex plate 231 and the concave plate 230, the convex plate 231 and the concave plate 230 are driven to approach each other by the sliding rod 232, so that the convex plate 231 and the concave plate 230 are spliced ​​with each other, and the clamping position of the convex plate 231 and the concave plate 230 is fixed by tightening the nut 233 on the outer wall of the sliding rod 232, so that the dorsal airbag 2202 is clamped inside them. In this way, not only the winding position of the dorsal airbag 2202 is fixed, but also the air pressure space inside the dorsal airbag 2202 can be compressed.

[0053] In summary, the working principle of this solution is as follows:

[0054] First, pull the support 11 to make it rotate on the outer wall of the rotating rod 121, so that the support 11 is separated from the base 1, and the thick rod 1220 is pulled upward from the base 1 by pulling the thin rod 1221. At the same time, the protruding rod 1223 rotates inside the base 1 to adjust the angle between the thin rod 1221 and the thick rod 1220. By rotating the thin rod 1221 to make it rotate on the outer wall of the screw rod 1222, the thin rod 1221 is forced to telescope inside the thick rod 1220 along the outer wall of the screw rod 1222, thereby adjusting the length of the thick rod 1220 and the thin rod 1221. This makes it easy to support the support 11 at any height and angle, and the end of the thin rod 1221 can be supported in the circular holes at different positions at the bottom of the support 11, so as to adjust the support angle of the support 11, so that the two pedals 2 are perpendicular or parallel to the ground, meeting the use needs of patients in different states;

[0055] Next, after placing the foot between the inflatable component 22 and the pedal board 2, the two slide bars 232 slide inside the pedal board 2 to adjust the distance between the convex plate 231 and the concave plate 230; when the dorsal airbag 2202 passes between the two, the slide bar 232 drives the convex plate 231 and the concave plate 230 to approach each other and splice, clamping the dorsal airbag 2202 inside, thereby fixing the winding position of the dorsal airbag 2202 and compressing the air pressure space inside the dorsal airbag 2202;

[0056] Then, during operation, the air cylinder 21 drives one pedal 2 to move upward and the other pedal 2 to move downward, so that the two air cylinders 223 move up and down respectively. The air cylinder 223 moving upward acts on the outer wall of the internal piston 224, so that the piston 224 generates a downward suction force, and the air pressure of the airbag 220 in the other pedal 2 is sucked into the airbag 220 of the pedal 2 through the hose 221, so that the airbag 220 of the upward pedal 2 expands, and the veins of the patient's foot are squeezed; for the pedal 2 moving downward, it drives the air cylinder 223 downward, and the piston 224 in the air cylinder 223 moves upward under the relative force, and the piston 224 squeezes the air cylinder 223, squeezes the gas into the airbag 220 through the trachea 222, and at the same time, the gas in the downward airbag 220 is input into the upward airbag 220 through the hose 221, accelerating its expansion speed, and shrinking the airbag 220 gas inside the downward pedal 2, so that the patient's foot veins are refilled and venous return is achieved;

[0057] The airbag 220 includes a plantar airbag 2201 and a dorsal airbag 2202, which can be filled or deflated to squeeze veins or promote reflux on the sole and dorsum of the patient's foot respectively; the dorsal airbag 2202 is wrapped around the patient's foot, and the patient's foot can be fixed between the dorsal airbag 2202 and the plantar airbag 2201, so that when the air pressure inside the two changes, the venous squeeze or reflux can be performed on the dorsum and sole of the patient's foot at the same time; when the wrapping position and size of the dorsal airbag 2202 are fixed, the air pressure space inside the dorsal airbag 2202 can also be squeezed and adjusted, so as to accurately adjust the inflation space according to the patient's specific condition and treatment needs, achieve more accurate pressure control, optimize the effect of promoting venous blood return, avoid abnormal local pressure due to improper inflation space, reduce the patient's discomfort during use, and enhance their treatment compliance;

[0058] In the single up and down reciprocating motion of the pedal 2, the "blood pumping" function of the veins caused by muscle contraction during normal walking or activities is simulated, thereby increasing the venous return rate, reducing blood congestion in the lower limb veins, and reducing the risk of venous thrombosis; in the up and down alternating motion of the two pedals 2, the process of the human body's natural walking in which the feet alternately push the blood back can be simulated, which can more effectively promote the flow of blood in the lower limb veins to the heart and reduce blood congestion. At the same time, the alternating motion of the feet can also exercise the patient's leg muscles to prevent muscle atrophy.
