Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a circulating cold compress device for orthopedic care. Background Art

[0002] Before and after orthopedic surgery or when a fracture occurs, swelling and pain often occur at the affected area of the patient, and cold compress is needed to reduce swelling and relieve pain. Applying an ice pack or a cold wet towel to the diseased area can cause local blood vessels to constrict, control bleeding of small blood vessels, and relieve pain of larger masses with high tension, achieving the effects of reducing swelling and relieving pain, reducing local blood flow, preventing the spread of inflammation and suppuration, and playing an important role in the care of the affected area of the patient.

[0003] Currently, the commonly used cold compress for care mostly directly applies an ice pack to the affected area. However, the temperature of the ice pack will increase over time, affecting the cold compress effect, and the pressure of the ice pack will cause compression on the affected area of the patient, causing discomfort to the patient. Even worse, it may cause secondary cracking of the affected area. In addition, the direct contact of the ice pack cold compress with the skin and limbs will damage nerves and other tissues after long-term placement of ice application.

[0004] Based on the above technical problems, some solutions have also been given in the prior art. For example, a Chinese patent with the authorization announcement number CN215131382U discloses a cold compress device for orthopedic care. The device turns on the refrigerator through the set switch. The cold air generated by the operation of the refrigerator is released into the refrigeration box through the set refrigeration pipe. The cold air cools down the condensation sheet through the set leather tube, and then the cold compress plate is placed on the part of the patient that needs cold compress. By setting a rubber pad on the surface of the cold compress plate, it can prevent the condensation sheet from being too cold and directly contacting the skin to cause skin frostbite to the patient.

[0005] However, in the actual cold compress care for orthopedic fractures or after surgery, the positions where the patient needs cold compress are variable. For example, in the care of swelling and pain caused by ankle joint fractures at the ankle, the cold compress device is required to fit the ankle joint completely. However, the shape of the ankle joint position is irregular, with the medial malleolus and lateral malleolus. For this scenario, whether using an ice pack for ice application in traditional technology or common cold compress devices in the prior art, neither can fit and wrap the medial malleolus or lateral malleolus on both sides of the ankle joint well, resulting in poor cold compress effect and affecting the swelling reduction effect after ankle joint fracture. Summary of the Invention

[0052] As Figures 1 to 10 shown, an embodiment of the present invention provides a circulating cold compress device for orthopedic care, including a fixing frame 1; a circulating cold compress main body 2 for providing a cold source is arranged on the front side of the upper surface of the fixing frame 1, a rotating assembly 4 is arranged at the upper end of the fixing frame 1 and is movably connected to an ankle positioning assembly 3 through the rotating assembly 4, and a control panel 5 for controlling the present application is arranged on the rotating assembly 4.

[0053] The circulating cold compress main body 2 includes a lower shell 21 fixedly connected to the front side of the upper surface of the fixing frame 1, a semiconductor refrigerator 24 is arranged inside the lower shell 21, an air pressure balance hole 25 is further opened on the outer surface of one side of the lower shell 21, an upper shell 27 is fixedly connected to the upper end of the lower shell 21, a heating plate 28 is fixedly connected to the inner wall of the upper shell 27, an air suction fan 26 is arranged at the connection position between the lower shell 21 and the upper shell 27, an air outlet pipe 23 is arranged on one side of the lower shell 21, an air inlet pipe 22 is arranged on one side of the upper shell 27, and the air outlet pipe 23 and the air inlet pipe 22 are respectively communicated to both sides of the ankle positioning assembly 3 to form an air flow circulation path.

[0054] As Figure 1 and Figure 2 shown, the rotating assembly 4 includes a first motor 41 fixedly connected to one side of the upper end of the fixing frame 1, the fixing frame 1 is arranged in a U shape, two connecting blocks 42 are symmetrically and rotatably connected to both ends of the upper end of the fixing frame 1, and the output shaft of the first motor 41 penetrates through the fixing frame 1 and is fixedly connected to one of the connecting blocks 42. A first telescopic rod 43 is fixedly connected to the lower end of each of the two connecting blocks 42, the ankle positioning assembly 3 is fixedly connected to the two first telescopic rods 43, and the control panel 5 is arranged on the upper surface of the upper end of the fixing frame 1 with a U-shaped structure.

[0055] During the cold compress process, the patient can use the control panel 5 to control the first motor 41 to work to drive the two groups of connecting blocks 42 to rotate, and further drive the two groups of first telescopic rods 43 to rotate. (The first telescopic rod 43 is used to adjust the position of the ankle positioning assembly 3 so that the device is suitable for people of different heights), thereby driving the ankle positioning assembly 3 to rotate to one side and raising the fractured and injured ankle of the patient, further promoting venous return, reducing tissue fluid return, and further facilitating the subsidence of ankle fracture swelling.

[0056] As shown Figures 1 to 4 in the figure, the ankle positioning assembly 3 includes single-ankle cold compress units respectively fixedly connected to two first telescopic rods 43, and an intermediate block 31 is fixedly connected between the two single-ankle cold compress units.

[0057] The single-ankle cold compress unit includes a cylindrical body 33 fixedly connected to the first telescopic rod 43. An annular airbag 32 is fixedly connected to the inner wall of the cylindrical body 33, and an air flow accommodation chamber is formed between the inner wall of the cylindrical body 33 and the annular airbag 32. The air outlet pipe 23 and the air inlet pipe 22 are respectively communicated with both sides of the air flow accommodation chamber.

[0058] Two air outlet pipes 23 and two air inlet pipes 22 are provided, corresponding to being connected to two groups of single-ankle cold compress units. Solenoid valves are provided on both the air outlet pipe 23 and the air inlet pipe 22 to control the opening and closing of the air flow passage of the single-ankle cold compress unit.

[0059] Aiming at the technical problem in the prior art that the medial malleolus or lateral malleolus on both sides of the ankle joint cannot be well attached and wrapped, resulting in poor cold compress effect and affecting the swelling reduction effect after ankle joint fracture. When the present invention works, first, the semiconductor refrigerator 24 is controlled to work through the control panel 5 to cool the gas inside the lower housing 21. At the same time, a temperature sensor is provided inside the lower housing 21 (this is prior art and will not be elaborated here). When the temperature sensor detects that the temperature inside the lower housing 21 is reduced to the target temperature required for cold compress, the control panel 5 controls the solenoid valves on the air outlet pipe 23 and the air inlet pipe 22 to open, and at the same time starts the suction fan 26 to pump the already refrigerated air inside the lower housing 21 into the upper housing 27, and discharges it into the ankle positioning assembly 3 through the air inlet pipe 22 communicated with the upper housing 27. When passing through the ankle positioning assembly 3, the cold air will enter the air flow accommodation chamber composed of the annular airbag 32 and the cylindrical body 33 and perform cold compress on the swollen ankle of the fracture. Then, the cold compress gas is discharged back into the lower housing 21 through the air outlet pipe 23 for cooling, forming a circulating cold compress effect. It should be noted that the ankle positioning assembly 3 internally includes two groups of single-ankle cold compress units. When specifically used, the solenoid valves on the corresponding air outlet pipe 23 and air inlet pipe 22 are opened according to the foot where the fracture is located, that is, ensuring that the two groups of single-ankle cold compress units work independently without affecting each other to better adapt to ankle fractures of the left or right foot. In addition, by providing the air pressure balance hole 25, when the two groups of single-ankle cold compress units work simultaneously, corresponding air can be inhaled from the outside into the circulation. When a single group of single-ankle cold compress units works, the excess gas inside can be discharged from the air pressure balance hole 25, thereby ensuring the balance of the internal and external air pressure and enabling the annular airbag 32 to be in an inflated state when working in different scenarios. A solenoid valve is provided inside the air pressure balance hole 25 and can be controlled through the control panel 5.

[0060] By providing a cyclic cold compress main body 2, compared with the prior art, especially in the scenario of ankle fractures, the annular airbag 32 can be used to fit the irregular protrusions at the ankle position, so that the medial malleolus or lateral malleolus on both sides of the ankle joint can be better fitted and wrapped, improving the cold compress effect of the device. At the same time, the present invention uses a semiconductor cooler 24 for refrigeration, and the cooled gas can be recycled for temperature reduction, avoiding the waste of residual cold energy. Compared with traditional ice compress methods, it does not require frequent manual replacement of ice packs, is more convenient to use, and the cold compress temperature can be adjusted by the semiconductor cooler 24 to achieve the optimal cold compress temperature to avoid damage to human tissues.

[0061] As Figures 4 to 8 shown, the ankle positioning assembly 3 further includes two positioning components. The positioning component includes a second motor 34 fixedly connected to the upper surface of the intermediate block 31. The output shaft of the second motor 34 is fixedly connected to a transmission shaft 35, and the lower end of the transmission shaft 35 extends through and into the interior of the intermediate block 31 and is fixedly connected to a transmission gear 36. The connection position between the intermediate block 31 and the side wall of the cylindrical body 33 is also rotatably connected to an intermediate gear 37, and the transmission gear 36 is meshed with the intermediate gear 37.

[0062] The upper and lower ends of the inner wall of the cylindrical body 33 are respectively embedded and rotatably connected with an upper annular gear 310 and a lower annular gear 311, and a gear connecting rod 312 is fixedly connected between the upper annular gear 310 and the lower annular gear 311; the upper annular gear 310 is meshed with the intermediate gear 37; an ankle fitting assembly 38 is further provided between the upper annular gear 310 and the lower annular gear 311. The ankle positioning assembly 3 is integrally arranged inside the air flow accommodation chamber formed by the annular airbag 32 and the cylindrical body 33 for realizing complete fitting of the annular airbag 32 with the ankle protrusion part.

[0063] As Figures 8 to 9 shown, the ankle fitting assembly 38 includes two holders 381 fixedly connected to the upper end of the upper annular gear 310 and the lower end of the lower annular gear 311 respectively. One end of each of the two holders 381 facing the inside of the upper annular gear 310 is fixedly connected with a second telescopic rod 382. One end of each of the two second telescopic rods 382 is fixedly connected with an upper arc-shaped housing 383 and a lower arc-shaped housing 384 respectively. Intermediate bodies 385 are fixedly connected to the middle positions inside the upper arc-shaped housing 383 and the lower arc-shaped housing 384 respectively. Two sets of fitting springs 386 are fixedly connected to both sides of the two sets of intermediate bodies 385. One end of each of the four sets of fitting springs 386 is fixedly connected with a sliding block 387. Hollow columns 3810 are fixedly connected between the opposite sides of the two sets of sliding blocks 387 in the vertical direction. Elastic ropes 3812 are fixedly connected between the two sets of hollow columns 3810 in the vertical direction. A number of deformation fitting pieces 3811 are linearly fixedly connected to both of the two elastic ropes 3812.

[0064] The two sets of the hollow columns 3810 are components made of hard rubber, and the deformation fitting piece 3811 is a disc-shaped component made of elastic rubber.

[0065] During operation, although the annular airbag 32 can achieve cold compress for the fracture at the ankle bulge to a certain extent, if it is desired to completely fit the ankle bulge, the air pressure inside the annular airbag 32 needs to be large enough to cause the annular airbag 32 to deform and fit the ankle bulge. However, excessive pressure will cause further damage to the fracture site and bring discomfort to the patient. Therefore, under normal cold compress pressure, the annular airbag 32 cannot completely fit the ankle bulge, so the cold compress effect needs to be improved.

[0066] In the present invention, by providing the ankle positioning assembly 3, during specific operation, the second motor 34 is started through the control panel 5. When the second motor 34 operates, it drives the transmission shaft 35 and the transmission gear 36 to rotate, thereby driving the intermediate gear 37 meshingly connected to the transmission gear 36 to rotate. When the intermediate gear 37 rotates, it further drives the upper annular gear 310 meshing with it to rotate, and drives the lower annular gear 311 to rotate through the gear connecting rod 312. When the upper annular gear 310 and the lower annular gear 311 rotate together, they drive the ankle fitting assembly 38 to rotate. When it rotates to the appropriate position, the operation of the second motor 34 is stopped, so that the ankle fitting assembly 38 is facing the ankle bulge fracture that needs cold compress. At this time, the ankle fitting assembly 38 starts to operate. The two second telescopic rods 382 are controlled through the control panel 5 to start extending, driving the ankle fitting assembly 38 to move. During the process of the ankle fitting assembly 38 moving towards the ankle fracture bulge, the position where the deformation fitting piece 3811 first squeezes the annular airbag 32 and pushes the annular airbag 32 to deform and contact the highest point of the ankle fracture bulge. Under the extrusion at the highest point of the swollen ankle fracture bulge, the elastic rope 3812 is stretched and extended, and protrudes towards the inner wall side of the upper annular gear 310. When the protrusion reaches a certain limit and the elastic rope 3812 is stretched to the longest, when the second telescopic rod 382 continues to extend and drive the ankle fitting assembly 38 to move, the combination of the two groups of hollow columns 3810, the deformation fitting piece 3811, and the elastic rope 3812 in the vertical direction will overcome the pulling force of the fitting spring 386 under the action of the extrusion force, drive the sliding block 387 to slide towards both sides inside the upper arc-shaped housing 383 and the lower arc-shaped housing 384, and make the combination of the two groups of hollow columns 3810, the deformation fitting piece 3811, and the elastic rope 3812 move towards both sides of the highest point of the ankle fracture bulge, synchronously squeezing the annular airbag 32, so that the annular airbag 32 deforms and fits the ankle fracture bulge. After the combination of the two groups of hollow columns 3810, the deformation fitting piece 3811, and the elastic rope 3812 reaches the lowest points on both sides of the ankle fracture bulge, the extension of the second telescopic rod 382 is stopped. At this time, under the extrusion of the combination of the two groups of hollow columns 3810, the deformation fitting piece 3811, and the elastic rope 3812, the annular airbag 32 here will completely fit the ankle fracture bulge, and when cold air passes through, a better cold compress effect will be achieved.

[0067] In the present invention, by providing the ankle positioning assembly 3, first of all, without increasing the overall air pressure of the annular airbag 32, the annular airbag 32 can be better fitted to the ankle fracture bulge, so that the air gap between the annular airbag 32 and the ankle fracture bulge disappears, and thus a better cold compress effect can be achieved. In addition, through the fitting of the ankle positioning assembly 3, it is not necessary to apply a large pressure to the ankle fracture bulge to make the annular airbag 32 fit the ankle fracture bulge, realizing the protection of the ankle fracture bulge and avoiding further damage to the fracture position.

[0068] As Figure 9 shown, negative electrode posts 389 are symmetrically arranged on both sides inside the upper arc-shaped housing 383. On the side of the slider 387 facing the negative electrode post 389 inside the upper arc-shaped housing 383, positive electrode posts 388 are fixedly connected respectively, and the negative electrode posts 389, positive electrode posts 388 are electrically connected to an external power supply.

[0069] After the combination of the two groups of hollow columns 3810, deformation fitting pieces 3811, and elastic ropes 3812 reaches the lowest points on both sides of the ankle fracture bulge, the slider 387 moves to both sides inside the upper arc-shaped housing 383, so that the negative electrode post 389 contacts the positive electrode post 388 and the circuit is connected. The single-chip microcomputer inside the control panel 5 is notified through an electrical signal. At this time, the fitting work on the ankle fracture bulge has been completed, so that the control panel 5 controls the second telescopic rod 382 to stop extending. Through this setting, the automation degree of the device can be further improved, and at the same time, the work of the ankle positioning component 3 can be better controlled.

[0070] As Figure 5 、 Figure 8 and Figure 10 shown, the ankle positioning component 3 further includes two groups of kneading components 39, and the upper and lower ends of the two groups of kneading components 39 are respectively fixedly connected to the cage 381.

[0071] The kneading component 39 includes two groups of third telescopic rods 391 fixedly connected to the cage 381. One ends of the two groups of third telescopic rods 391 are commonly fixedly connected with a bow-shaped frame 392. A middle holding block 393 is fixedly connected to the middle position of the bow-shaped frame 392. A third motor 394 is fixedly connected to one side of the middle holding block 393. The output shaft of the third motor 394 penetrates through the middle holding block 393 and is fixedly connected with a connecting rotating rod 395. A rotating cylinder 396 is fixedly connected to one side of the outer circular surface of the connecting rotating rod 395, and the connecting rotating rod 395 and the rotating cylinder 396 are not coaxially arranged. One end of the rotating cylinder 396 is fixedly connected with a warping rod 3911. A kneading plate 399 is fixedly connected to one side of the warping rod 3911. Kneading spheres 3910 are evenly distributed in a ring on the circular surface of one side of the kneading plate 399. Limiting frames 397 are fixedly connected to the cross bars on both sides of the bow-shaped frame 392. A spherical through hole is opened at the middle position of the limiting frame 397. A rotating holding ball 398 is fixedly connected to the warping rod 3911, and the rotating holding ball 398 is rotatably connected with the spherical through hole.

[0072] When the bow-shaped frame 392 is installed, its convex position faces the side wall of the cylindrical body 33. The whole kneading component 39 refers to Figure 5, which is also arranged inside the air flow accommodating chamber formed by the annular airbag 32 and the cylindrical body 33. After the combination of the two groups of hollow columns 3810, the deformation fitting pieces 3811, and the elastic ropes 3812 reaches the lowest points on both sides of the ankle fracture bulge, the third expansion link 391 can be extended to enable the kneading ball 3910 and the kneading plate 399 to squeeze the annular airbag 32 in contact with the highest point of the ankle fracture bulge, so as to form kneading on the ankle fracture bulge.

[0073] During the treatment of ankle fracture swelling, ice compress should be selected in the first 48 hours, and hot compress should be selected after 48 hours. The existing ice compress device only has the ice compress effect. If you want to achieve hot compress, you need to use it in combination with a hot water bag, and the operation is relatively cumbersome and inconvenient.

[0074] When the present invention performs hot compress operation after 48 hours, only the semiconductor refrigerator 24 needs to be controlled to turn off, and at the same time, the heating plate 28 is started. In this way, when the suction fan 26 works, hot compress gas can be filled into the air flow accommodating chamber formed by the annular airbag 32 and the cylindrical body 33. At this time, the ankle positioning component 3 can also make the annular airbag 32 close to the ankle fracture site (the specific working process of the ankle positioning component 3 will not be elaborated here) to ensure the hot compress effect. At the same time, by setting the kneading component 39, during the hot compress process, the third expansion link 391 can be extended by operating the control panel 5, driving the bow-shaped frame 392 and the components installed thereon to move together until multiple kneading balls 3910 contact the ankle fracture site. At this time, the third motor 394 is controlled to work, driving the connecting rotating rod 395 to rotate, and further driving the rotating cylinder 396 to rotate. When the rotating cylinder 396 rotates, it will drive the rocker 3911 to rotate. Since the rotation maintaining ball 398 fixedly connected to the rocker 3911 rotates and is limited inside the limiting frame 397, through the rocker 3911, the rotation of the rotating cylinder 396 will drive the kneading plate 399 at the other end of the rocker 3911 to perform a circular motion, and the kneading balls 3910 are used to knead and reduce swelling on the swollen ankle fracture of the patient, thereby further improving the swelling reduction effect of the device.

[0075] The working process of the technical solution of the present invention is as follows:

[0076] In use, first, the semiconductor refrigerator 24 is controlled by the control panel 5 to operate, cooling the gas inside the lower housing 21. At the same time, a temperature sensor is provided inside the lower housing 21 (this is prior art and will not be elaborated here). When the temperature sensor detects that the internal control of the lower housing 21 has dropped to the target temperature required for cold compress, the control panel 5 controls the solenoid valves on the air outlet pipe 23 and the air inlet pipe 22 to open, and at the same time starts the suction fan 26, pumping the cooled air inside the lower housing 21 into the upper housing 27 and discharging it into the ankle positioning assembly 3 through the air inlet pipe 22 communicating with the upper housing 27. When passing through the ankle positioning assembly 3, the cold air will enter the airflow accommodating chamber composed of the annular airbag 32 and the cylinder body 33 and perform cold compress on the fractured and swollen ankle. Then, the cold-compressed air is discharged back into the lower housing 21 through the air outlet pipe 23 for cooling, forming a cyclic cold-compress effect. It should be noted that the ankle positioning assembly 3 contains two single-ankle cold-compress units. Specifically in use, according to the foot where the fracture is located, the solenoid valves on the corresponding air outlet pipe 23 and air inlet pipe 22 are opened, that is, ensuring that the two single-ankle cold-compress units work independently without affecting each other to better adapt to ankle fractures of the left or right foot.

[0077] During operation, the second motor 34 is started through the control panel 5. When the second motor 34 operates, it drives the transmission shaft 35 and the transmission gear 36 to rotate, thereby driving the intermediate gear 37 meshed with the transmission gear 36 to rotate. When the intermediate gear 37 rotates, it further drives the upper annular gear 310 meshed with it to rotate, and drives the lower annular gear 311 to rotate through the gear connecting rod 312. When the upper annular gear 310 and the lower annular gear 311 rotate together, they drive the ankle fitting assembly 38 to rotate. When it rotates to the appropriate position, the operation of the second motor 34 is stopped, so that the ankle fitting assembly 38 is directly opposite to the ankle convex fracture site that needs cold compress. At this time, the ankle fitting assembly 38 starts to work, and the two second telescopic rods 382 start to extend, driving the ankle fitting assembly 38 to move. During the movement of the ankle fitting assembly 38 towards the ankle fracture convexity, the position where the deformation fitting piece 3811 first contacts the highest point of the ankle fracture convexity. Under the extrusion of the highest point of the swollen ankle fracture convexity, the elastic rope 3812 is stretched and extended, and bulges towards one side of the inner wall of the upper annular gear 310. When it bulges to a certain limit and the elastic rope 3812 is stretched to the longest, when the second telescopic rod 382 continues to extend and drive the ankle fitting assembly 38 to move, the combination of the two groups of hollow columns 3810, the deformation fitting piece 3811, and the elastic rope 3812 in the vertical direction will overcome the pulling force of the fitting spring 386 under the action of the extrusion force, drive the sliding block 387 to slide towards both sides inside the upper arc-shaped housing 383 and the lower arc-shaped housing 384, and make the combination of the two groups of hollow columns 3810, the deformation fitting piece 3811, and the elastic rope 3812 move towards both sides of the highest point of the ankle fracture convexity. After the combination of the two groups of hollow columns 3810, the deformation fitting piece 3811, and the elastic rope 3812 reaches the lowest points on both sides of the ankle fracture convexity, the extension of the second telescopic rod 382 is stopped. At this time, under the extrusion of the combination of the two groups of hollow columns 3810, the deformation fitting piece 3811, and the elastic rope 3812, the annular airbag 32 here will completely fit on the ankle fracture convexity, and when the cold air passes through, a better cold compress effect will be achieved.
