Description

Technical Field

[0001] The invention relates to the technical field of physical medicine and rehabilitation therapy, in particular to a physical therapy device for closed soft tissue injury of ankle joint. Background Art

[0002] Closed soft tissue injury of the ankle joint is a common disease in clinical practice, mainly manifested by pain, swelling, and subcutaneous ecchymosis. The cause of the disease is the destruction of local tissue cells caused by external force, capillary rupture and bleeding to form hematoma or stasis, and the release of various inflammatory mediators to increase vascular permeability, leading to increased exudation and swelling. If the injury is not properly treated after the injury occurs, it can aggravate the internal bleeding and exudation of the damaged area, exacerbating the pain and swelling. How to effectively treat closed soft tissue injury of the ankle joint has always been a research hotspot in the field of physical medicine and rehabilitation therapy technology.

[0003] According to the pathological conditions, closed soft tissue injuries of the ankle joint can be divided into the stage of tissue destruction, bleeding, and hematoma formation; the stage of local inflammation, edema, cell infiltration, and tissue necrosis; and the stage of tissue repair. Currently, the treatment of closed soft tissue injuries mainly follows the POLICE principle, namely, protection, optimal loading, ice, compression, and elevation of the affected limb.

[0004] At present, when dealing with acute closed soft tissue injuries of the ankle joint, medical staff are often relied on to perform cumbersome bandaging, cold compresses, support and fixation operations on the injured. When dealing with subacute and chronic closed soft tissue injuries of the ankle joint, rehabilitation therapists are also relied on to perform occupational therapy such as hot compresses and massage on patients. Each process of ice compress, hot compress, pressure bandage, fixed support, etc. is extremely cumbersome and consumes a lot of energy and physical strength of medical staff. In addition, since the current ice compress and hot compress mainly use ice cubes, hot towels, chemical ice packs, chemical hot packs, etc., the temperature is extremely difficult to control accurately, and the pressure of the pressure bandage is also difficult to control accurately. In view of this, the research aims to design and realize a physical therapy device for closed soft tissue injuries of the ankle joint, in order to solve the problem that the current treatment of closed soft tissue injuries of the ankle joint is cumbersome, and the temperature and pressure of traditional ice compress and hot compress are difficult to control accurately.

[0005] Announcement No.: CN110200730A proposes a brace for ankle joint fixation, which includes a brace body, a calf strap set, an ankle protective cover, a storage bag, an insulation component, and an adjustable partition. The device as a whole can perform ice compresses on the ankle joint in the acute phase, hot compresses in the subacute and chronic phases, ankle joint fixation protection, etc. The adjustable partition design can adjust the temperature during hot compresses, and the storage bag can hold Chinese medicine tablets, which can accelerate recovery when combined with heat therapy. The shortcoming of this device is that it cannot accurately control the temperature of cold compresses or hot compresses, and because it is an upper open design and lacks an upper covering mechanism, it is also difficult to apply pressure bandages to the inner and outer ankle parts of the distal fibula and tibia.

[0006] Announcement No.: CN111658302A discloses an emergency medical ankle sprain ice fixation frame, which mainly includes a base, a support plate, a support column, an adjustment mechanism, etc. The device can apply ice to different parts of the human ankle, and can externally fix the affected limb, which can help medical personnel to deal with acute closed soft tissue injuries of the ankle joint conveniently and efficiently. The shortcoming of this equipment is that it lacks the extremely important pressurized bandage function, and the realization of the cold compress function of the device depends on the cooperation of ice bags. In actual use, the temperature of the ice bag will increase with the increase of cold compress time, so it is impossible to effectively and accurately control the temperature of the injured part. Not only that, the device is also unable to perform hot compresses or massages on the injured part during the subacute and chronic stages of the injury, which is not conducive to the overall recovery of the injury.

[0007] Announcement No.: CN212853782U discloses an ankle joint ice compress device, including a first track, a second track, a seat and an ice compress structure. The device solves the current problem that ice bags or cold towels rely on medical staff to manually press and support, and the patient can also adjust the angle independently to maintain a comfortable posture for ice compress treatment. The shortcoming of the equipment is that it is too large, and the place of use can only be a relatively fixed hospital or physiotherapy room, etc., and it cannot be quickly adapted and used when an injury occurs. In addition, the core component cold compress structure is too simple compared to the overall design of the device, and the function can only achieve conventional cold compress treatment of the injured part, and it lacks necessary functions such as pressure bandaging, hot compress treatment in the later stage of injury, support and external fixation.

[0008] Announcement No.: CN208510124U discloses an ankle brace that can be used both for ice and heat, and the main structure of the ankle brace is a sleeve-shaped ankle brace body. The ankle brace body includes an elastic strip and a net bag for storing ice packs or heating pads, which can better fit the ankle joint of the human body. The utility model has beautiful appearance, is easy to use, and can be used for both ice and heat. While protecting the ankle joint, you can ice or heat the injured part without taking it off. Although this technology solves the problem of cumbersome ice or heat compress operations, the device still cannot accurately control the temperature, and the elastic ankle brace cannot provide sufficient support and pressure. In addition, due to the pull-on design, some patients with severe injuries have limited ankle movement due to swelling or pain, making it impossible or difficult to complete plantar flexion and thus unable to wear the device.

[0009] Announcement No.: CN209172663U proposes an improved ankle ice pack, including an ice pack strap that wraps around the human ankle and a walking base that fits the human foot. The device can facilitate patients to carry out basic activities while receiving ice treatment, solving the problem that traditional ice packs require manual support all the time, which is inconvenient for patients to carry out activities. However, the shortcoming of the device is that it cannot generate heat, and the temperature of the ice pack cannot be well controlled. At the same time, it also lacks sufficient support external fixation and pressurization mechanisms, and the size of the walking base cannot be adjusted according to the needs of the patient. Overall, the device as a whole cannot meet the actual treatment needs of patients with closed soft tissue injuries of the ankle joint.

[0010] Announcement No.: CN210872392U discloses an early ice shoe for patients with foot and ankle fractures, which mainly includes a sole and an ice cloth surface. The device solves the current problem of relying on manual fixation of ice towels or ice bags in the early stage of closed ankle injuries. The zipper design of the upper makes it easier for patients to wear the device, and the multi-layer design of shoe cloth, ice layer, sponge layer, and waterproof layer in the ice cavity greatly improves the patient's comfort. The shortcoming of the equipment is that it cannot be adjusted in size to adapt to patients with different injuries, and it still relies on ice bags and cold towels. It is impossible to maintain a constant temperature and adjust the bandaging pressure, and it is impossible to provide hot compress treatment to the affected area in the later stage of the injury. Therefore, the overall equipment still lacks some functions required by the principles of ankle injury treatment in actual use.

[0011] Announcement No.: CN112022498A discloses an automatic kneading device for ice compress, including a rod, a support leg, a reinforcing rib, a limb placement part, a height adjustment mechanism, etc. The device solves the problems of easy frostbite of the skin during ice compress treatment, cumbersome operation of repeatedly moving ice packs, and the inability of patients to knead the affected part to promote recovery. The shortcomings of the device are that as a type of cold compress device, it is relatively large in size, the temperature control of the injured part is not accurate, and it cannot be well matched and applied to the ankle joint of the human body. Summary of the invention

[0012] The purpose of the present invention is to provide a physical therapy device for closed soft tissue injury of the ankle joint, which has a reasonable structure, safe and reliable performance, and various treatment functions. Constant pressure ice compress external fixation can effectively reduce the bleeding in the injured tissue and subjective pain of the patient, while avoiding secondary injury to the injured part. Pulse pressurized hot compress can effectively promote blood circulation in the injured part, effectively reduce the swelling of the injured part to promote recovery.

[0013] The objective of the present invention is achieved as follows: a physical therapy device for closed soft tissue injury of ankle joint, wherein a main control mechanism, an adjustable shell mechanism, a coating liquid bag mechanism, a pressure regulating mechanism, a temperature regulating mechanism, and a human-computer interaction mechanism are arranged on the inner side of an annular outer buckle, wherein the structure of the main control mechanism is that an AT89S51 single-chip microcomputer and a removable lithium battery are installed on the inner side of the annular outer buckle through an annular outer buckle slot arranged thereon; the structure of the adjustable shell mechanism is an ankle-shaped shell mounted on the surface of the coating liquid bag mechanism, comprising an adjustable shell main body section, a tibia and fibula section, and a plantar section; the structure of the coating liquid bag mechanism is a two-part flexible ankle-shaped liquid bag located inside the adjustable shell mechanism, which is connected through a coating liquid bag interconnection port; the structure of the pressure regulating mechanism is located on the annular outer buckle The KLP40 liquid pump on the inside and the HX711 pressure sensor inside the tibia and fibula of the coated liquid bag, the KLP40 liquid pump is fixed on the inner side of the annular outer buckle through the annular outer buckle slot, and is connected to the coated liquid bag through the delivery port on the adjustable outer shell of the tibia and fibula, and the HX711 pressure sensor is fixed on the inner side of the tibia and fibula of the flexible ankle-shaped liquid bag; the structure of the temperature adjustment mechanism is the DS18B20 temperature sensor, XH-C1206S semiconductor refrigeration sheet, and CT-JRP404020 alumina ceramic heating sheet located on the surface of the coated liquid bag, all of which are bonded to the surface of the coated liquid bag; the structure of the human-computer interaction mechanism is a matrix button and LCD1602 liquid crystal display installed on the adjustable outer shell of the plantar segment, which is fixed to the top of the adjustable outer shell of the plantar segment.

[0014] Based on the physical therapy principles and actual clinical rehabilitation treatment methods for closed soft tissue injuries of the ankle joint, the present invention determines the design goals to have support and external fixation functions, constant temperature cold compress function, constant temperature hot compress function, pressurized bandage function, flexible massage function and personalized rapid adaptation function. After clarifying the design goals, the SolidWorks2021 software was used to draw the model, and the entire system was divided into several relatively independent modules, mainly including the main control mechanism, adjustable shell mechanism, coating liquid bag mechanism, pressure adjustment mechanism, temperature adjustment mechanism, and human-computer interaction mechanism.

[0015] The present invention has two modes: constant pressure ice compress external fixation and pulse pressure hot compress. Users can conveniently use the device to perform constant temperature cold compress and pressure bandage external fixation on the injured part, and can also use it to perform pulse pressure massage and constant temperature hot compress on the ankle joint.

[0016] The main control mechanism consists of a ring-shaped outer buckle, an AT89S51 single-chip microcomputer, a removable lithium battery, and a ring-shaped battery shell. The ring-shaped outer buckle slot located inside the ring-shaped outer buckle is fixed with the AT89S51 single-chip microcomputer, and the removable lithium battery is fixed inside the ring-shaped battery shell. The ring-shaped outer buckle is connected to the back of the ring-shaped battery shell, and the front is connected through the ring-shaped outer buckle quick connection buckle. The ring-shaped outer buckle and the ring-shaped battery shell are both made of polycarbonate material, and the removable battery uses a 7500mAh / 12V lithium battery.

[0017] The adjustable shell mechanism is composed of an adjustable shell main body section, an adjustable scale plate for the plantar section, an adjustable shell plantar section, an adjustable scale plate for the tibia and fibula section, an adjustable shell tibia and fibula section, a quick connection buckle, and a foam filling layer. The front side of the adjustable shell main body section is connected to the adjustable shell plantar section through the adjustable scale plate for the plantar section to adjust the length of the shell plantar section, the upper part of the adjustable shell main body section is connected to the adjustable shell tibia and fibula section through the adjustable scale plate for the tibia and fibula section to adjust the length of the shell tibia and fibula section, the rear surface of the adjustable shell main body section is provided with an adjustable shell main body section quick connection buckle to connect the left and right main body section shells, the upper and lower surfaces of the adjustable shell plantar section are respectively provided with plantar section shell quick connection buckle ① and plantar section shell quick connection buckle ② to connect the left and right plantar section shells, and the rear and front surfaces of the adjustable shell tibia and fibula section are respectively provided with tibia and fibula shell quick connection buckle ① and tibia and fibula shell quick connection buckle ② to connect the left and right tibia and fibula section shells. Each section of the outer shell is a hollow structure, and a foam filling layer is arranged inside the hollow structure to improve the temperature control effect of the device.

[0018] The adjustable shell main body, plantar segment adjustable scale plate, adjustable shell plantar segment, tibia and fibula adjustable scale plate, and adjustable shell tibia and fibula are all made of polycarbonate material, the quick connection buckle is made of stainless steel material, and the foam filling layer is filled with phenolic foam, which has the advantages of light material, low price, and good insulation performance.

[0019] Before use, the patient can adjust the depth of the adjustable scale plate of the plantar segment and the adjustable scale plate of the tibia and fibula segment embedded in the main body of the shell independently and quickly according to needs, so as to adjust the size of the adjustable shell mechanism, so that the ankle joint can better fit the device. After adjusting the size of the shell, the user can easily connect the quick connection buckle on the surface of the shell, so that the two parts of the shell are covered on the damaged ankle joint, thereby quickly achieving effective external fixation and protection, and at the same time providing a guarantee for the subsequent coating liquid bag to better fit the damaged part.

[0020] The coating liquid bag mechanism consists of a coating liquid bag liquid input port, a flexible ankle-shaped liquid bag, and a coating liquid bag intercommunication port. The coating liquid bag liquid input port is set above the coating liquid bag mechanism. The liquid input port passes through the adjustable outer shell tibia and fibula section port and is connected to the liquid pump output port. The pressure in the coating liquid bag can be adjusted by the KLP40 liquid pump. The two parts of the flexible ankle-shaped liquid bag of the coating liquid bag mechanism are connected through the coating liquid bag intercommunication port to keep the pressure and liquid temperature of the two parts of the liquid bag constant. The split design of the coating liquid bag is conducive to the user's use in the case of limited joint movement after a closed soft tissue injury of the ankle joint. The user can place the affected part in the coating liquid bag mechanism independently and quickly without plantar flexion or other ankle joint movements, which effectively avoids re-injury caused by ankle joint movement during the wearing process.

[0021] The pressure regulating mechanism is composed of a KLP40 liquid pump, an HX711 pressure sensor, an adjustable housing tibia and fibula section port, and a liquid pump outlet. The KLP40 liquid pump of the pressure regulating mechanism is connected to the liquid pump outlet through the adjustable housing tibia and fibula section port. The pressure in the coated liquid bag mechanism can be adjusted by pressurizing or depressurizing the KLP40 liquid pump controlled by the human-machine interaction mechanism. The HX711 pressure sensor is fixed on the inner side of the tibia and fibula section of the flexible ankle-shaped liquid bag. The sensor can collect the pressure value of the flexible ankle-shaped liquid bag and the human ankle joint in real time.

[0022] The KLP40 liquid pump has the advantages of stable performance, small size, and low price, and the HX711 pressure sensor has the advantages of high measurement accuracy, low cost, and small size, so the two are selected as the core components of the device's pressure regulation. After the user wears the device, he can select the boost mode and set the pressure parameters through the matrix buttons in the human-computer interaction mechanism. Then the device realizes pressure regulation under the control of the single-chip microcomputer, and the pressure value at the joint between the flexible ankle-shaped liquid bag and the human ankle joint is fed back in real time on the LCD1602 liquid crystal display in the human-computer interaction mechanism.

[0023] The temperature regulating mechanism is composed of a DS18B20 temperature sensor, an XH-C1206S semiconductor cooling sheet, and a CT-JRP404020 alumina ceramic heating sheet. The DS18B20 temperature sensor in the temperature regulating mechanism is fixed to the inner side of the lower part of the coating liquid bag, the XH-C1206S semiconductor cooling sheet is fixed to the outer side of the middle part of the coating liquid bag, and the CT-JRP404020 alumina ceramic heating sheet is also fixed to the outer side of the middle part of the coating liquid bag. After wearing the device, the patient can select the desired temperature range through the matrix button. After the device is powered on, the DS18B20 temperature sensor is used to collect the temperature data of the coating liquid bag in real time. The main control mechanism controls the XH-C1206S semiconductor cooling sheet and the CT-JRP404020 alumina ceramic heating sheet to work or rest to achieve temperature control.

[0024] DS18B20 is a single-line digital sensor with a measurement range of -55℃~+125℃ and an accuracy of up to ±0.5℃. The XH-C1206S cooling chip has a voltage of 12V and a power of 72W. It is widely used in the field of all-solid-state refrigeration. It has the advantages of small size, no sliding parts, and low noise. The CT-JRP404020 alumina ceramic heating chip has a voltage of 12V and a power of 18W. It has the characteristics of good insulation, small size, and high thermal efficiency.

[0025] The human-machine interaction mechanism is composed of a matrix button and an LCD1602 liquid crystal display screen. The matrix button and the LCD1602 liquid crystal display screen of the human-machine interaction mechanism are integrated and fixed above the plantar section of the adjustable shell. The matrix button includes a pressure reduction button, a pressure increase button, a temperature reduction button, and a temperature increase button. Pressure or temperature adjustment instructions can be input through the matrix button, and the LCD1602 liquid crystal display screen can provide real-time feedback of pressure, temperature values ​​and power information.

[0026] The invention has a reasonable structure, safe and reliable performance, and diverse treatment functions. It can quickly adapt to users and provide protection and fixation, constant temperature ice compress, constant temperature hot compress, pressure bandage, pulse massage and other functions required for injury treatment and rehabilitation. It effectively improves the physical treatment effect and standardization of closed soft tissue injuries of the ankle joint, and reduces the workload of therapists and the social medical burden.
