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, the patient's affected area often experiences swelling and pain, and needs to be treated with cold compresses to reduce swelling and relieve pain. Applying ice packs or cold, wet towels to the affected area can promote local vasoconstriction, control bleeding from small blood vessels, and reduce pain from larger tension masses, thereby reducing swelling and relieving pain. It can reduce local blood flow, prevent the spread of inflammation and suppuration, and plays a very important role in the care of the patient's affected area.

[0003] Currently, the most commonly used cold compress care method is to apply an ice bag directly to the affected area. However, the temperature of the ice bag will increase over time, affecting the effect of the cold compress. The pressure of the ice bag will compress the patient's affected area, causing discomfort to the patient. What's worse, it may cause secondary cracking of the affected area. In addition, the ice bag is in direct contact with the skin and limbs, and long-term use of the ice pack will damage nerves and other tissues.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, a Chinese patent with authorization announcement number CN215131382U discloses a cold compress device for orthopedic care. The device turns on the refrigerator through a set switch, and the cold air generated by the operation of the refrigerator is released into the refrigerator box through a set refrigeration pipe. The cold air cools the condenser through a set leather pipe, and then is placed on the part of the patient that needs cold compress through a set cold compress plate. By arranging a rubber pad on the surface of the cold compress plate, it can be prevented that the condenser plate is overcooled and directly contacts the skin of the patient to cause frostbite on the skin;

[0005] However, in actual cold compress care for orthopedic fractures or after surgery, the locations where patients need cold compress vary. For example, in the care for swelling and pain caused by ankle fractures at the ankle, the cold compress equipment needs to be able to completely fit the ankle joint. However, the ankle joint is located in an irregular shape, with an inner ankle bone and an outer ankle bone. For this scenario, whether it is the use of ice bags for ice compresses in traditional technology or the common cold compress equipment in the prior art, it is impossible to better fit and wrap the inner ankle bones or outer ankle bones on both sides of the ankle joint, resulting in poor cold compress effects, which affects the swelling reduction effect after ankle fractures.

[0052] like Figures 1 to 10 As 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 body 2 for providing a cold source is provided on the front side of the upper surface of the fixing frame 1, a rotating component 4 is provided at the upper end of the fixing frame 1 and an ankle positioning component 3 is movably connected via the rotating component 4, and a control panel 5 for operating the present application is provided on the rotating component 4.

[0053] The circulating cold compress 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 opened on the outer surface of one side of the lower shell 21, the upper end of the lower shell 21 is fixedly connected to the upper shell 27, the inner wall of the upper shell 27 is fixedly connected to the heating plate 28, and a 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 connected to the two sides of the ankle positioning component 3 to form an air flow passage.

[0054] like Figure 1 and Figure 2 As shown, the rotating assembly 4 includes a No. 1 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, and the two side ends of the upper end of the fixing frame 1 are symmetrically rotatably connected to two connecting blocks 42, and the output shaft of the No. 1 motor 41 passes through the fixing frame 1 and is fixedly connected to one of the connecting blocks 42, and the lower ends of the two connecting blocks 42 are fixedly connected to a No. 1 telescopic rod 43, the ankle positioning assembly 3 is fixedly connected to the two No. 1 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 No. 1 motor 41 to drive the two sets of connecting blocks 42 to rotate, and further drive the two sets of No. 1 telescopic rods 43 to rotate (the No. 1 telescopic rods 43 are used to adjust the position of the ankle positioning component 3, so that the device is suitable for people of different heights), thereby driving the ankle positioning component 3 to rotate to one side and lift the patient's fractured ankle, thereby promoting venous return, reducing tissue fluid return, and further facilitating the reduction of swelling of the ankle fracture.

[0056] like Figures 1 to 4 As shown, the ankle positioning assembly 3 includes a single ankle cold compress unit fixedly connected to two No. 1 telescopic rods 43 respectively, and a middle 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 a telescopic rod 43, an annular airbag 32 is fixedly connected to the inner wall of the cylindrical body 33, and an airflow accommodating chamber is formed between the inner wall of the cylindrical body 33 and the annular airbag 32, and the air outlet pipe 23 and the air inlet pipe 22 are respectively connected to the two sides of the airflow accommodating chamber.

[0058] There are two air outlet pipes 23 and two air inlet pipes 22, which are connected to the two groups of single ankle cold compress units respectively, and solenoid valves are provided on the air outlet pipes 23 and the air inlet pipes 22 to control the opening and closing of the air flow passages of the single ankle cold compress units.

[0059] In view of the technical problem in the prior art that the inner or outer ankle bones on both sides of the ankle joint cannot be well fitted and wrapped, resulting in poor cold compress effect and affecting the swelling reduction effect after ankle fracture, when the present invention is working, firstly, the control panel 5 is used to control the semiconductor refrigerator 24 to work, so as to cool down the gas inside the lower shell 21. At the same time, a temperature sensor is arranged inside the lower shell 21 (this is the prior art and will not be described in detail here). When the temperature sensor detects that the temperature inside the lower shell 21 is reduced to the target temperature required for cold compress, the control panel 5 controls the electromagnetic valves on the air outlet pipe 23 and the air inlet pipe 22 to open, and at the same time, the suction fan 26 is started to draw the refrigerated air inside the lower shell 21 into the upper shell 27, and discharge it into the ankle positioning component 3 through the air inlet pipe 22 connected with the upper shell 27. When passing through the ankle positioning component 3, the cold air will enter the air flow containing chamber composed of the annular air bag 32 and the cylindrical body 33. A cold compress is applied to the swollen ankle due to the fracture, and then the gas after the cold compress is re-discharged into the lower shell 21 through the air outlet pipe 23 for cooling, thereby forming a circulating cold compress effect. It should be noted that the ankle positioning component 3 contains two groups of single ankle cold compress units. During specific use, the corresponding solenoid valves on the air outlet pipe 23 and the air inlet pipe 22 are opened according to the foot where the fracture is located, thereby ensuring that the two groups of single ankle cold compress units work independently without affecting each other, so as to better adapt to ankle fractures of the left or right foot. In addition, by providing an air pressure balance hole 25, when the two groups of single ankle cold compress units work at the same time, the corresponding air can be inhaled from the outside into the circulation. When a single group of single ankle cold compress units works, the excess internal gas can be discharged from the air pressure balance hole 25, thereby ensuring the balance of internal and external air pressures, so that the annular airbag 32 can be in an expanded state when working in different scenarios. A solenoid valve is provided inside the air pressure balance hole 25, which can be controlled by the control panel 5.

[0060] Compared with the prior art, the present invention sets a circulating cold compress body 2. Especially in the scenario of ankle fracture, the annular airbag 32 can be used to fit the irregular protrusion of the ankle position, so as to better fit and wrap the inner ankle bone or the outer ankle bone on both sides of the ankle joint, thereby improving the cold compress effect of the device. At the same time, the present invention uses a semiconductor refrigerator 24 for cooling, and the gas after the cold compress can be circulated for cooling and use to avoid the waste of residual cold. Compared with traditional ice compress methods, there is no need for frequent manual replacement of ice bags, which is more convenient to use, and the cold compress temperature can be adjusted by the semiconductor refrigerator 24 to achieve the optimal cold compress temperature to avoid damage to human tissue.

[0061] like Figures 4 to 8 As shown, the ankle positioning assembly 3 also includes two groups of positioning assemblies, and the positioning assembly includes a No. 2 motor 34 fixedly connected to the upper surface of the middle block 31, and the output shaft of the No. 2 motor 34 is fixedly connected with a transmission shaft 35, and the lower end of the transmission shaft 35 extends through the inside of the middle block 31 and is fixedly connected to a transmission gear 36. The connection position between the middle block 31 and the side wall of the cylinder 33 is also rotatably connected to an intermediate gear 37, and the transmission gear 36 is meshingly connected with the intermediate gear 37.

[0062] An upper ring gear 310 and a lower ring gear 311 are respectively embedded and rotatably connected at the upper and lower ends of the inner wall of the cylindrical body 33, and a gear connecting rod 312 is fixedly connected between the upper ring gear 310 and the lower ring gear 311; the upper ring gear 310 is meshingly connected with the intermediate gear 37; an ankle fitting component 38 is also provided between the upper ring gear 310 and the lower ring gear 311, and the ankle positioning component 3 is arranged as a whole inside the airflow containing chamber formed by the annular airbag 32 and the cylindrical body 33, so as to achieve complete fitting of the annular airbag 32 with the raised part of the ankle.

[0063] like Figures 8 to 9 As shown, the ankle fitting assembly 38 includes two retaining frames 381 respectively connected to the upper end of the upper ring gear 310 and the lower end of the lower ring gear 311, and the two retaining frames 381 are respectively connected to the second telescopic rod 382 at one end facing the inner side of the upper ring gear 310, and the two second telescopic rods 382 are respectively connected to the upper arc shell 383 and the lower arc shell 384 at one end, and the middle position inside the upper arc shell 383 and the lower arc shell 384 is The two sets of intermediate bodies 385 are fixedly connected, and two sets of fitting springs 386 are fixedly connected to both sides of the two sets of intermediate bodies 385. One ends of the four sets of fitting springs 386 are fixedly connected to sliding blocks 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 plurality of deformable fitting sheets 3811 are linearly fixedly connected to the two elastic ropes 3812.

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

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

[0066] The present invention sets an ankle positioning component 3. When working, the second motor 34 is started through the control panel 5. When the second motor 34 is working, it will drive the transmission shaft 35 and the transmission gear 36 to rotate, and then drive the intermediate gear 37 meshing with the transmission gear 36 to rotate. When the intermediate gear 37 rotates, it will further drive the upper ring gear 310 meshing with it to rotate, and drive the lower ring gear 311 to rotate through the gear connecting rod 312. When the upper ring gear 310 and the lower ring gear 311 rotate together, it will drive the ankle fitting component 38 to rotate. When it rotates to a suitable position, Stop the operation of the No. 2 motor 34 so that the ankle fitting component 38 is facing the ankle protrusion fracture that needs cold compress. At this time, the ankle fitting component 38 starts to work, and the two No. 2 telescopic rods 382 are controlled by the control panel 5 to start extending, driving the ankle fitting component 38 to move. In the process of the ankle fitting component 38 moving toward the ankle fracture protrusion, the position of the deformable fitting sheet 3811 first squeezes the annular airbag 32, and pushes the annular airbag 32 to deform and contact the highest point of the ankle fracture protrusion, and under the squeezing at the highest point of the swollen ankle fracture protrusion, the elastic rope 3812 is stretched and elongated. , and protrudes toward one side of the inner wall of the upward ring gear 310. When it protrudes to a certain limit and the elastic rope 3812 is stretched to its longest length, when the second telescopic rod 382 continues to extend to drive the ankle fitting component 38 to move, the combination of the two groups of hollow columns 3810 in the vertical direction, the deformable fitting sheet 3811, and the elastic rope 3812 will overcome the pulling force of the fitting spring 386 under the action of the extrusion force, and drive the sliding block 387 to slide to both sides inside the upper arc-shaped shell 383 and the lower arc-shaped shell 384, and make the two groups of hollow columns 3810, the deformable fitting sheet 3811, and the elastic rope 3812 The combination moves toward both sides of the highest point of the ankle fracture protrusion, and simultaneously squeezes the annular airbag 32, so that the annular airbag 32 is deformed to fit the ankle fracture protrusion. After the combination of the two groups of hollow columns 3810, the deformable fitting pieces 3811, and the elastic rope 3812 reaches the lowest points on both sides of the ankle fracture protrusion, the extension of the second telescopic rod 382 is stopped. At this time, under the squeezing of the combination of the two groups of hollow columns 3810, the deformable fitting pieces 3811, and the elastic rope 3812, the annular airbag 32 here will be completely fitted to the ankle fracture protrusion, and when the cold air passes through, a better cold compress effect will be achieved.

[0067] The present invention provides an ankle positioning component 3. Firstly, without increasing the overall air pressure of the annular airbag 32, the annular airbag 32 can be better fitted to the ankle fracture protrusion, so that the air gap between the annular airbag 32 and the ankle fracture protrusion disappears, thereby achieving a better cold compress effect. In addition, through the fitting of the ankle positioning component 3, there is no need to apply a large pressure to the ankle fracture protrusion to make the annular airbag 32 fit the ankle fracture protrusion, thereby achieving protection for the ankle fracture protrusion and avoiding further damage to the fracture position.

[0068] like Fig. 9 As shown, negative poles 389 are symmetrically provided on both sides of the upper arc-shaped shell 383, and the sliding block 387 located inside the upper arc-shaped shell 383 is fixedly connected with positive poles 388 on the side facing the negative poles 389, and the negative poles 389 and the positive poles 388 are electrically connected to the external power supply.

[0069] After the combination of the two groups of hollow columns 3810, the deformable fitting sheet 3811 and the elastic rope 3812 reaches the lowest point on both sides of the ankle fracture protrusion, the sliding block 387 moves to the positions on both sides inside the upper arc-shaped shell 383, so that the negative pole 389 contacts the positive pole 388 and connects the circuit, and notifies the internal microcontroller of the control panel 5 through an electrical signal. At this time, the fitting work on the ankle fracture protrusion has been completed, so that the control panel 5 controls the second telescopic rod 382 to stop extending. Through this setting, the degree of automation of the device can be further improved, and at the same time, the operation of the ankle positioning component 3 can be better controlled.

[0070] like Figure 5 , Figure 8 and Fig.10 As shown, the ankle positioning assembly 3 further includes two groups of massaging assemblies 39 , and the upper and lower ends of the two groups of massaging assemblies 39 are respectively fixedly connected to the retaining frame 381 .

[0071] The kneading assembly 39 comprises two groups of No. 3 telescopic rods 391 fixedly connected to the retaining frame 381, one end of the two groups of No. 3 telescopic rods 391 are commonly fixedly connected to a bow frame 392, the middle position of the bow frame 392 is fixedly connected to an intermediate retaining block 393, one side of the intermediate retaining block 393 is fixedly connected to a No. 3 motor 394, the output shaft of the No. 3 motor 394 passes through the intermediate retaining block 393 and is fixedly connected to a connecting rod 395, one side of the outer circumference of the connecting rotating rod 395 is fixedly connected to a rotating cylinder 396, and the connecting rotating rod 395 is fixedly connected to a rotating cylinder 396. 95 is non-coaxially arranged with the rotating cylinder 396, one end of the rotating cylinder 396 is fixedly connected to the tilting rod 3911, one side of the tilting rod 3911 is fixedly connected to the kneading plate 399, and the kneading balls 3910 are evenly distributed in a ring shape on the circular surface of one side of the kneading plate 399, the limit frames 397 are fixedly connected at the cross bars on both sides of the bow frame 392, a spherical through hole is opened in the middle position of the limit frame 397, the tilting rod 3911 is fixedly connected to the rotating retaining ball 398, and the rotating retaining ball 398 is rotatably connected to the spherical through hole.

[0072] When the bow-shaped frame 392 is installed, its protruding position faces the side wall of the cylindrical body 33, and the massaging assembly 39 is generally Figure 5It is also arranged inside the airflow containing chamber formed by the annular airbag 32 and the cylindrical body 33. After the two groups of hollow columns 3810 and the combination of the deformable fitting sheet 3811 and the elastic rope 3812 reach the lowest points on both sides of the ankle fracture protrusion, the massage ball 3910 and the massage plate 399 can be extended by extending the No. 3 telescopic rod 391 to squeeze the annular airbag 32 in contact with the highest point of the ankle fracture protrusion, thereby massaging the ankle fracture protrusion.

[0073] In the treatment of swelling at the ankle fracture, ice compress should be used in the first 48 hours, and hot compress should be used after 48 hours. The existing ice compress device only has an ice compress effect. If you want to achieve hot compress, you need to use it with a hot water bag, which is cumbersome and inconvenient to operate.

[0074] When the present invention is used for hot compress operation after 48 hours, it is only necessary to control the semiconductor refrigerator 24 to be turned off and start the heating plate 28 at the same time. In this way, when the suction fan 26 is working, the air flow containing chamber formed by the annular airbag 32 and the cylindrical body 33 can be filled with hot compress gas. At this time, the ankle positioning component 3 can also make the annular airbag 32 close to the ankle fracture (the specific working process of the ankle positioning component 3 is not repeated here) to ensure the effect of hot compress. At the same time, by setting the massage component 39, during the hot compress process, the control panel 5 can be used to control the extension of the third telescopic rod 391 to drive the bow frame 392 and the components installed thereon to move together until A plurality of groups of massage balls 3910 contact the ankle fracture. 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 tilting rod 3911 to rotate. Since the rotating retaining ball 398 fixedly connected to the tilting rod 3911 rotates inside the limit frame 397 and is limited at the same time, the rotation of the rotating cylinder 396 through the tilting rod 3911 will drive the massage plate 399 at the other end of the tilting rod 3911 to make a circular motion, and the massage balls 3910 are used to massage and reduce swelling of the patient's ankle fracture, thereby further improving the detumescence effect of the device.

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

[0076] When in use, firstly, the semiconductor refrigerator 24 is controlled to work through the control panel 5 to cool down the gas inside the lower shell 21. At the same time, a temperature sensor is provided inside the lower shell 21 (this is the prior art and will not be described in detail here). When the temperature sensor detects that the temperature inside the lower shell 21 is lowered to the target temperature required for cold compress, the control panel 5 controls the electromagnetic valves on the air outlet duct 23 and the air inlet duct 22 to open, and starts the suction fan 26 at the same time to draw the refrigerated air inside the lower shell 21 into the upper shell 27, and discharge it into the ankle positioning assembly 3 through the air inlet duct 22 connected to the upper shell 27, and then passes through the ankle positioning assembly 3. When the ankle positioning component 3 is in use, cold air will enter the air flow containing chamber composed of the annular airbag 32 and the cylindrical body 33, and perform cold compress on the swollen ankle due to the fracture. Then, the gas after the cold compress is discharged into the lower shell 21 through the air outlet pipe 23 for cooling, thereby forming a circulating cold compress effect. It should be noted that the ankle positioning component 3 contains two groups of single ankle cold compress units. When in use, the corresponding solenoid valves on the air outlet pipe 23 and the air inlet pipe 22 are opened according to the foot where the fracture is located, thereby ensuring that the two groups of single ankle cold compress units work independently without affecting each other, so as to better adapt to ankle fractures of the left or right foot.

[0077] When working, the second motor 34 is started through the control panel 5. When the second motor 34 is working, it will drive the transmission shaft 35 and the transmission gear 36 to rotate, and then drive the intermediate gear 37 meshing with the transmission gear 36 to rotate. When the intermediate gear 37 rotates, it will further drive the upper ring gear 310 meshing with it to rotate, and drive the lower ring gear 311 to rotate through the gear connecting rod 312. When the upper ring gear 310 and the lower ring gear 311 rotate together, they will drive the ankle fitting component 38 to rotate. When it rotates to a suitable position, When the ankle fitting component 38 is in the state of being placed, the operation of the No. 2 motor 34 is stopped, so that the ankle fitting component 38 is directly opposite to the ankle protrusion fracture part that needs cold compress. At this time, the ankle fitting component 38 starts to work, and the two No. 2 telescopic rods 382 start to extend, driving the ankle fitting component 38 to move. In the process of the ankle fitting component 38 moving toward the ankle fracture protrusion, the position of the deformed fitting sheet 3811 first contacts the highest point of the ankle fracture protrusion, and under the pressure of the highest point of the swollen ankle fracture protrusion, the elastic rope 3812 is stretched and extended, and the circular gear 3812 moves upward. One side of the inner wall of the wheel 310 is convex, and when it convexes to a certain limit and the elastic rope 3812 is stretched to the longest, when the second telescopic rod 382 continues to stretch to drive the ankle fitting component 38 to move, the combination of the two groups of hollow columns 3810 in the vertical direction, the deformable fitting sheet 3811, and the elastic rope 3812 will overcome the pulling force of the fitting spring 386 under the action of the extrusion force, and drive the sliding block 387 to slide to both sides inside the upper arc shell 383 and the lower arc shell 384, so that the two groups of hollow columns 3810 and the deformable fitting sheet 3811 can be moved. The combination of the two groups of hollow columns 3810, the deformable fitting sheet 3811 and the elastic rope 3812 moves toward the highest point of the ankle fracture protrusion on both sides. After the combination of the two groups of hollow columns 3810, the deformable fitting sheet 3811 and the elastic rope 3812 reaches the lowest points on both sides of the ankle fracture protrusion, the extension of the second telescopic rod 382 is stopped. At this time, under the squeezing of the two groups of hollow columns 3810, the deformable fitting sheet 3811 and the elastic rope 3812, the annular airbag 32 here will be completely fitted on the ankle fracture protrusion, and when the cold air passes through, a better cold compress effect will be achieved.
