Description

Technical Field

[0001] The utility model relates to the technical field of medical training devices, in particular to a training device for preventing deep vein thrombosis. Background Art

[0002] Deep vein thrombosis refers to the abnormal coagulation of blood in the deep vein cavity, which blocks the venous lumen and leads to venous reflux obstruction, causing clinical symptoms such as distal venous hypertension, limb swelling, pain and superficial vein dilation. It is more common in the lower limbs and can cause varying degrees of chronic deep venous insufficiency, which can cause disability in severe cases. The functional exercise frame is suitable for long-term bedridden patients in intensive care units and wards. It can be installed at the head or foot of the bed. When installed at the head of the bed, awake patients can actively exercise their upper limbs. Medical staff can assist patients with unconsciousness or drug-sedated patients in activities to reduce the incidence of muscle weakness in intensive care unit patients.

[0003] In the prior art, for example, Chinese patent CN217091956U discloses a training device for preventing deep vein thrombosis of lower limbs, which includes a plate, a rectangular block, a baffle, a fixed block, a spring, a training plate and a square plate. The top surface of the concave plate is fixedly connected with a rectangular block, and the rear end of the top surface of the concave plate is fixedly connected with a baffle. In the utility model, the massage stick and the foot pad are used to solve the problem that the existing deep vein thrombosis training device has a relatively single function, is inconvenient to use, and affects the actual use effect. By placing the foot on the top of the concave plate, the foot steps on the training plate, and actively performs ankle dorsiflexion activities, the foot and lower limbs of the patient can be trained, which improves the practicality. At the same time, the rotating shaft and the massage stick are arranged on the surface of the training plate. When the user performs foot training, the rotating shaft and the massage stick massage the user's foot to relieve training fatigue.

[0004] In the above patent, people step on the foot pad to make the foot pad intermittently squeeze the spring, and cooperate with the elastic reset effect of the compression spring to exercise the lower limbs, which has a good exercise effect. However, the spring is set between two fixed blocks to connect the foot pad and the baffle together. The fixed elastic value of the compression spring makes it difficult to advance when some patients have insufficient lower limb strength, and the reverse thrust on the patient's lower limbs is too large. When some patients have sufficient lower limb strength, the spring is easily squeezed, and the reverse thrust on the patient's lower limbs is insufficient. It cannot be adjusted according to the needs of the user population, which reduces the use effect of the deep vein thrombosis prevention trainer. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a deep vein thrombosis prevention training device, including: a base 1; an adjustment component 2, the adjustment component 2 is set into two groups, and the two groups of adjustment components 2 are symmetrically arranged on the top of the mounting frame 201, the adjustment component 2 includes a mounting frame 201, the mounting frame 201 is fixedly connected to the top of the base 1, a first fixing rod 204 is fixedly connected between the outer surfaces of the mounting frame 201, and a compression spring 205 is sleeved on the outer surface of the first fixing rod 204, and a motor 202 is fixedly connected to the rear surface of the mounting frame 201, and the output end of the motor 202 rotates through The rear surface of the mounting frame 201 and the output end of the motor 202 are fixedly connected with a threaded rod 210, the outer surface of the threaded rod 210 is threadedly rotatably connected with a push plate 203, the inner surface of the push plate 203 is slidably connected with the outer surface of the first fixed rod 204, the outer surface of the first fixed rod 204 is slidably connected with a first mounting plate 206 away from the front surface of the push plate 203, the front surface of the first mounting plate 206 is symmetrically fixedly connected with connecting rods 208, the front end surfaces of the two connecting rods 208 are fixedly connected with a second mounting plate 212, and the second mounting plate 21 2 is fixedly connected to a connecting block 213, the inner surface wall of the connecting block 213 is rotatably connected to a fixing block 214, the front end surface of the fixing block 214 is fixedly connected to a pedal 215, the outer surface of the mounting frame 201 is fixedly connected to a position away from the first fixing rod 204, the outer surface of the second fixing rod 209 slides through the front surface of the pushing plate 203, the compression spring 205 is located between the opposite outer surfaces of the pushing plate 203 and the first mounting plate 206, the bottom of the first mounting plate 206 is fixedly connected to a connecting frame 211, and the connecting frame 211 is fixedly connected to the first mounting plate 206. The inner surface of the frame 211 is slidably connected to the outer surface of the second fixed rod 209, the length of the connecting rod 208 is greater than the length of the first fixed rod 204, a rubber pad 207 is set near the top position on the front surface of the mounting frame 201, and the rubber pad 207 is matched with the second mounting plate 212. A plurality of raised blocks 216 are equidistantly set on the front surface of the pedal 215, and the plurality of raised blocks 216 are vertical. The outer surface of the threaded rod 210 rotates away from the position of the motor 202 and penetrates the outer surface of the mounting frame 201, and the threaded rod 210 is rotatably connected to the mounting frame 201.

[0024] The effect achieved by the entire embodiment 1 is that when training to prevent deep vein thrombosis, the base 1 is first fixed at a suitable training location. The base 1 can rely on its own gravity or contact it with the wall at the position of the bedside lamp. The person maintains a lying posture and contacts the surfaces of the two pedals 215 with both feet respectively, and then actively performs ankle dorsiflexion activities or directly steps on the pedals 215. The multiple vertical protrusions 216 arranged on the surface of the pedals 215 play a massage role and increase the friction between the pedals 215 and the feet. The pedals 215 are rotatably connected to the connecting blocks 213 through the fixing blocks 214, so the pedals 215 can As the foot moves, it rotates synchronously, changes its original vertical direction, and transmits the pedaling force to the surface of the second mounting plate 212, driving the connecting rod 208 to move backward, which pushes the first mounting plate 206 and the connecting frame 211 to slide backward on the outer surfaces of the first fixing rod 204 and the second fixing rod 209 respectively. The connecting frame 211 limits the first mounting plate 206 to prevent the position of the pedal 215 from shifting. At this time, the compression spring 205 deforms and contracts under the action of the extrusion force. The rubber pad 207 set on the front surface of the mounting frame 201 can block the second mounting plate 212, play a buffering role, and prevent excessive pedaling force. The second mounting plate 212 collides with the mounting frame 201, generating a loud noise. The compression spring 205 stretches outward under its own elastic restoring action, generating a reverse thrust on the first mounting plate 206. After the user's foot retracts, the pedal 215 is reset. This reciprocating cycle accelerates the blood circulation of the lower limbs and plays a role in exercise. When the user feels that the pressure is too small, the motor 202 is started, and its output end drives the threaded rod 210 to rotate forward in the inner wall of the mounting frame 201. In the process of driving the threaded rod 210 to rotate synchronously, the push plate slides forward along the surface of the second fixing rod 209 for a distance, and the compression spring 205 is pressed. The expansion space of the compression spring 205 is increased, which reduces the elasticity value of the spring. By controlling the expansion space of the compression spring 205, personnel can adjust the reverse thrust of the pedal 215 as needed to avoid the compression spring 205 with fixed elastic force being too large or too small for some personnel, which affects their exercise and thus improves the use effect of the deep vein thrombosis prevention trainer.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a fixing frame 3 is fixedly connected to the front surface of the base 1 near the top, a third fixing rod 6 is fixedly connected to the inner surface of the fixing frame 3, a roller 4 is rotatably connected to the outer surface of the third fixing rod 6, and a plurality of through holes 5 are equidistantly provided on the outer surface of one side of the roller 4.

[0026] The effect achieved by the entire embodiment 2 is that, when in use, the fixing frame 3 is fixedly connected to the front surface of the base 1 near the top, and the inner surface of the fixing frame 3 is fixedly connected to the third fixing rod 6, and the surface of the fixing frame 3 is rotatably connected to the roller 4. A plurality of through holes 5 are equidistantly provided on one side of the roller 4 to reduce the weight of the roller 4, so that when a person actively performs ankle dorsiflexion by stepping on the pedal 215, the lower limb area can roll on the surface of the roller 4, and while supporting the person's lower limbs, massage can be performed during the rolling friction between the roller 4 and the lower limbs, thereby further improving the use effect of the deep vein thrombosis prevention trainer.

[0027] Working principle: When in use, first fix the base 1 at a suitable training location, the person maintains a lying posture, and puts both feet against the surface of the two pedals 215 respectively, with the lower limbs above the roller 4, and then actively performs ankle dorsiflexion activities, or directly steps on the pedal 215, and the thrust is transmitted to the two connecting rods 208 through the fixing block 214 and the connecting block 213 of the connecting structure, pushing the first mounting plate 206, so that the first mounting plate 206 and the connecting frame 211 slide backward on the outer surfaces of the first fixing rod 204 and the second fixing rod 209 respectively. Under the squeezing action of the thrust, the compression spring 205 is deformed and contracted under the squeezing, and the compression spring 205 becomes shorter as the shrinking distance becomes shorter, and its own elastic reset elasticity gradually increases, generating a large reverse thrust on the first mounting plate 206. After the person's feet retract, the pedal 215 is reset, and this reciprocating cycle is repeated to accelerate the downward movement. The output end of the motor 202 rotates in the opposite direction to drive the push plate 203 to move backward, increasing the extension space of the compression spring 205, which has the effect of reducing the spring elasticity value. By controlling the extension space of the compression spring 205, the personnel can adjust the reverse thrust of the pedal 215 according to the needs, so as to avoid the compression spring 205 with fixed elastic force having too large or too small reverse thrust for some personnel, which affects the personnel's exercise, thereby improving the use effect of the deep vein thrombosis prevention trainer.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
