Description

Technical Field

[0001] This invention relates to the field of ankle joint care technology, and in particular to a microenvironmental cooling garment care device for preoperative ankle joint injury. Background Technology

[0002] The field of joint care technology mainly involves the protection, maintenance, and damage prevention of various joints in the human body, as well as tissue intervention after disease intervention. The core issues in this field cover the mechanical load management, inflammation control, and physiological homeostasis regulation of bone, joint cartilage, ligaments, synovium, and surrounding muscle tissue. It typically includes daily physical therapy such as hot and cold compresses, joint mobility training, muscle strengthening, traction therapy, and perioperative care measures before and after specific surgeries. It maintains the anatomical integrity of the joint by physically intervening in the microenvironment, blood circulation, nerve conduction, and tissue metabolic state.

[0003] Currently, when performing preoperative cold acclimatization care for patients with ankle injuries, the routine clinical procedure often involves nurses directly applying ice packs to the affected area of ​​the ankle. However, manually applying ice packs can easily create an air gap between the ice pack and the skin. Air has poor thermal conductivity, resulting in significant thermal barrier effects, leading to low cold transfer efficiency, uneven cooling, and unstable results. Furthermore, the overall temperature of the ice pack cannot be adjusted, maintaining a consistently low temperature throughout the procedure. This makes it impossible to adjust the intensity of cold stimulation according to the patient's tolerance and the progress of cold acclimatization, making it difficult to accurately create the appropriate cold acclimatization microenvironment. It also increases the risk of local tingling, numbness, or even frostbite due to continuous low-temperature stimulation, posing significant safety risks. Additionally, manual application requires constant supervision by the nurse. This practice not only consumes a significant amount of manpower and greatly increases the workload of nursing staff, but also makes it difficult to keep ice packs in a fixed position. Ice packs are prone to slipping and shifting, causing misalignment of the cold stimulation area, disrupting the continuity of cold acclimatization training, and significantly reducing the effectiveness of care. Furthermore, traditional ice packs lack temperature detection capabilities, preventing medical staff from monitoring the actual temperature of the affected skin in real time. They can only rely on experience to judge the duration and intensity of cold compresses, a typical experience-based nursing model. If the local temperature becomes too low, it cannot be detected and intervened in time, further increasing the risk of frostbite. Simultaneously, ice pack cold compresses lack corresponding limb restraint structures, allowing patients' ankles to move freely. This exacerbates the problem of ice pack displacement and makes the injured area prone to traction and twisting, posing a risk of secondary injury to the affected area. Summary of the Invention

[0004] This invention provides a microenvironment cold acclimatization nursing device for preoperative ankle joint injury, which solves the technical problems of current methods where nurses use ice packs to apply cold compresses to patients' ankles, resulting in unstable effects and the inability to adjust the overall temperature of the ice packs according to the patient's tolerance and the gradient of cold acclimatization training.

[0009] Optionally, the second support frame is C-shaped, and both the first support frame and the second support frame are made of plastic. The second support frame is provided with a protective sleeve, a first adhesive strip on one side of the protective sleeve, a second adhesive strip on the other side of the protective sleeve, a zipper on the top of the protective sleeve, a first hollowed-out groove on the protective sleeve corresponding to the position of the microenvironment cold-weather clothing care device body, and a second hollowed-out groove on the protective sleeve corresponding to the position of the temperature measuring instrument body.

[0010] Optionally, the first support plate holder is provided with a first lightweight groove, and the second support plate holder is provided with a second lightweight groove at equal intervals.

[0011] Optionally, both sides of the second support plate frame are provided with bends, the second support plate frame is an arc-shaped structure that protrudes to the bottom, the top of the second support plate frame is provided with a first pad, and the bottom of the first pad is provided with protrusions that are equidistant from each other and adapted to the shape of the second lightweight groove.

[0012] Optionally, a third support frame is fixedly connected to the top of the base, a second pad is installed on the third support frame, and a segmented groove is provided on the footrest, the shape of which is adapted to the contour of the human heel.

[0013] Optionally, a first connecting frame is fixedly connected to the side of the first support frame near the fourth support frame, and an electric telescopic rod is installed on the first connecting frame. The output end of the electric telescopic rod is connected to the support base.

[0014] Optionally, a third connecting frame is fixedly connected to the side of the first support plate frame near the fourth support frame, and a guide portion is provided on the side of the third connecting frame away from the first support plate frame.

[0015] Optionally, a second connecting frame is installed on the body of the temperature measuring instrument. A movable block is fixedly connected to the side of the second connecting frame near the body of the microenvironment cold-weather clothing care device. Buffer cavities are provided on both sides of the movable block. An movable groove adapted to the shape of the movable block is opened on the side of the body of the microenvironment cold-weather clothing care device near the body of the temperature measuring instrument.

[0016] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0017] In the above solution, by setting up the main body of the microenvironment cold acclimatization nursing device, the main body of the temperature measuring instrument, and the foot support and limiting mechanism, the thermal barrier and temperature measurement interference caused by the air layer can be eliminated. This ensures efficient conduction of cold energy, making the cold compress cooling effect stable and uniform, and also ensures accurate and reliable temperature data. At the same time, it can prevent the components from shifting, keep the installation position fixed, make the cold stimulation distribution more even, reduce local discomfort for patients, and ensure the smooth implementation of preoperative cold acclimatization nursing. When applying cold compresses to the patient's ankle, the foot support and limiting mechanism, which consists of the second support frame, the first support plate frame, the second support plate frame, and the foot support, can support and limit the patient's calf root and foot sole, so that the foot can remain stable when the patient is undergoing microenvironment cold acclimatization training in the ankle area, ensuring the cold acclimatization effect, while also preventing accidental ankle movement and preventing secondary injury to the patient.

[0018] By setting up a guide structure that combines an electric telescopic rod, a slider, and a groove, when the skin temperature exceeds a preset safety threshold or the system determines that the cold stimulation intensity is excessive, the electric telescopic rod drives the support base to move, moving the microenvironment cold acclimatization garment care device and the cold compress components away from the ankle area, ensuring the safety of cold acclimatization garment operation. Furthermore, the force slider and groove limit the movement trajectory of the support base, ensuring that the support base and the microenvironment cold acclimatization garment care device move smoothly under the drive of the electric telescopic rod, effectively preventing deviation and ensuring the precise movement of the cold compress components.

[0019] By setting up a first support frame, a second support frame, and a footrest with elastic deformation capabilities, it can adaptively deform according to the patient's leg contour to form a semi-enclosed restraint, which conforms to the curve of the human body while improving the support and restraint effect, resulting in better wearing comfort. When used with the footrest, it also restrains the patient's heel and calf root, further stabilizing the ankle and thus ensuring the cold adaptation effect.

[0020] By setting up a protective sleeve, a first adhesive strip, a second adhesive strip, a zipper, and a matching sealing strip, an independent and sealed space can be created in the ankle area to isolate the influence of external airflow, stabilize the local low temperature environment, and further improve the effect of cold-weather clothing.

[0021] By setting two sets of tightening straps, the tightness can be flexibly adjusted according to different patients' foot shapes, making it highly adaptable. At the same time, it further reinforces the body of the microenvironment cold adaptation clothing care device, ensuring that the cold compress area is always in close contact with the affected area. In addition, the first and second tightening straps are elastic and do not affect the movement of the microenvironment cold adaptation clothing care device body when subjected to the electric telescopic rod.

[0022] This device features a partial wrapping design, leaving the toes unrestricted and allowing for unimpeded blood circulation: the toes are exposed and can flex and extend independently, relying on the muscle pump action to accelerate venous return in the foot, significantly reducing foot congestion and swelling, and solving the common problems of coldness and swelling in the distal part of the foot after full foot wrapping.

[0023] In summary, this device has a simple structure, is easy to install and use, and is highly adaptable. It also has multiple advantages such as precise temperature control, real-time temperature measurement, stable positioning, and safety protection, which can effectively improve the overall quality and safety of preoperative cold acclimatization clothing care for ankle injuries.

[0035] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 9As shown, an embodiment of the present invention provides a preoperative microenvironmental cold acclimatization garment nursing device for ankle joint injuries, including a base 1. The base 1 has an L-shaped cross-section and a stable overall structure, serving as an integral support base. A first support frame 2 is mounted on the top of the base 1, and a support seat 3 is fixedly connected to the top of the first support frame 2. The microenvironmental cold acclimatization garment nursing device body 4 is mounted on the top of the support seat 3. A temperature measuring instrument body 5 is mounted on one side of the microenvironmental cold acclimatization garment nursing device body 4. A foot support and limiting mechanism is mounted on the top of the base 1, and the foot support and limiting mechanism includes a second support frame 6 mounted on the base 1. The second support frame 6... A first support frame 7 is installed at the top, and a second support frame 8 is installed at the top of the first support frame 7. The foot support and limiting mechanism also includes a footrest 14. A fourth support frame 13 is fixedly connected to the bottom of the footrest 14. The fourth support frame 13 is connected to the side wall of the base 1. The microenvironment cold acclimatization clothing care device body 4 and the temperature measuring instrument body 5 are existing mature components, and their conventional structure and working principle will not be described in detail. The microenvironment cold acclimatization clothing care device body 4 is used to apply cold compresses to the patient's ankle. The cold medium flow can be adjusted by the controller to achieve precise temperature control. The temperature measuring instrument body 5 is used to collect the skin temperature of the affected area in real time.

[0037] This device combines skin temperature, pain score, and ankle circumference changes to comprehensively determine the patient's preoperative condition. It uses the training target temperature as the boundary for cold stimulation progression, integrates the cold compress output temperature with the ward ambient temperature, and performs data noise reduction processing, abandoning the traditional method of relying on experience for cold compresses with ice packs. The system compares the temperature difference with the preset threshold in real time, and combines the prompt range and abnormal range to coordinate and constrain the cold medium flow. It also issues nursing rhythm reminders in a timely manner, so that the cooling intensity, analgesic effect, and edema control effect are adapted to the patient's physical tolerance, effectively improving the stability of preoperative cold adaptation and the safety of nursing work.

[0038] During use, the main body 4 of the microenvironment cold acclimatization garment nursing device and the main body 5 of the temperature measuring instrument must be placed in close contact with the patient's skin. This eliminates thermal barrier and temperature measurement interference caused by the air layer, ensuring efficient conduction of cold energy, stable and uniform cooling effect, and accurate and reliable temperature data. At the same time, it prevents the components from shifting, keeps the installation position fixed, makes the cold stimulation distribution more even, reduces local discomfort for the patient, and ensures the smooth implementation of preoperative cold acclimatization nursing. When applying cold compresses to the patient's ankle, the foot support and limiting mechanism, composed of the second support frame 6, the first support plate frame 7, the second support plate frame 8, and the foot support 14, can support and limit the patient's calf root and foot sole, so that the foot can remain stable when the patient is undergoing microenvironment cold acclimatization training in the ankle area, ensuring the effect of cold acclimatization, and also preventing accidental ankle movement and secondary injury to the patient.

[0039] like Figure 1 and Figure 2 As shown, a third support frame 11 is fixedly connected to the top of the base 1. A second pad 12 is installed on the third support frame 11. The third support frame 11 can provide stable support for the second pad 12, ensuring that the second pad 12 is firmly installed and not easily displaced. The third support frame 11 is used in conjunction with the second pad 12 to limit the patient's foot, thereby further ensuring that the patient's foot is in a stable state.

[0040] Both ends of the first support frame 2 are equipped with sliders. The base 1 has a groove 17 that matches the shape of the slider. The first support frame 7 is fixedly connected to the first connecting frame 15 on the side near the fourth support frame 13. An electric telescopic rod 16 is installed on the first connecting frame 15. The output end of the electric telescopic rod 16 is connected to the support seat 3. The electric telescopic rod 16 is used to push the support seat 3 to move, thereby driving the body 4 of the microenvironment cold adaptation garment nursing device to complete the action of close contact or separation with the patient's ankle. The electric telescopic rod 16 is a mature existing technology, and its working principle and specific structure will not be described in detail here. Relying on the cooperation between the slider and the groove 17, the movement trajectory of the support seat 3 can be limited and guided, so that the support seat 3 moves smoothly and does not deviate when driven by the electric telescopic rod 16.

[0041] like Figure 5 As shown, a cooling compress component 19 is provided on one side of the main body 4 of the microenvironment cooling acclimatization garment care device. The side of the cooling compress component 19 that fits the patient's ankle is adapted to the shape of the ankle. The main body 4 of the microenvironment cooling acclimatization garment care device transfers cold energy to the patient's ankle through the cooling compress component 19, with sufficient contact area and uniform cold energy conduction. Figure 2 As shown, the microenvironmental cooling clothing care device body 4 has a first tightening strap 24 on one side and a second tightening strap 25 on the other side. In use, the first tightening strap 24 is wrapped around the patient's foot, and the second tightening strap 25 is wrapped around the patient's ankle. The first and second tightening straps 24 and 25 are then glued together, and the tightness is adjusted according to different foot shapes. Both the first and second tightening straps 24 and 25 are elastic. This structure not only firmly fixes the microenvironmental cooling clothing care device body 4 to the affected area but also ensures that the cold compress component 19 fits tightly to the patient's ankle, effectively guaranteeing the implementation effect of the microenvironmental cooling clothing at the ankle.

[0042] like Figure 1 and Figure 4As shown, the shape of the support base 3 is adapted to the bottom contour shape of the microenvironment cooling clothing care device body 4, ensuring the stability of the installation of the microenvironment cooling clothing care device body 4. The top of the support base 3 is fixedly connected to the limiting block 18, and the bottom of the microenvironment cooling clothing care device body 4 is provided with a slot adapted to the shape of the limiting block 18. The support base 3 and the microenvironment cooling clothing care device body 4 are aligned and installed through a plug-in structure, which is convenient for assembly and further strengthens the connection between the two, effectively preventing the microenvironment cooling clothing care device body 4 from shifting during use.

[0043] like Figure 1 and Figure 2 As shown, the second support frame 6 is C-shaped and provides stable support for the first support frame 7 and the second support frame 8. Both the first support frame 7 and the second support frame 8 are made of plastic and can undergo moderate elastic deformation under external force. When the patient's lower leg is placed on the second support frame 8, the first support frame 7 and the second support frame 8 deform under the action of gravity, forming a semi-enclosed restraint on the patient's lower leg. The second support frame 8 is provided with a protective sleeve 10, which can form a complete wrap around the patient's ankle. The protective sleeve 10 can be made of heat-insulating and transparent material. One side of the protective sleeve 10 is provided with a first adhesive strip 28, and the other side of the protective sleeve 10 is provided with a second adhesive strip 29. When in use, the first adhesive strip 28 and the second adhesive strip 29 are in close contact with the patient's skin to achieve a seal on both sides of the protective sleeve 10.

[0044] The top of the protective sleeve 10 is equipped with a zipper 30, which can both close the upper space of the protective sleeve 10 and be quickly opened, making it convenient to wrap the protective sleeve 10 around the patient's foot or remove it. The protective sleeve 10 has a first hollowed-out groove 26 near the body 4 of the microenvironment cold acclimatization garment care device, and a second hollowed-out groove 27 near the body 5 of the temperature measuring instrument. Both the first hollowed-out groove 26 and the second hollowed-out groove 27 are equipped with sealing strips. In use, the sealing strip at the first hollowed-out groove 26 is fitted onto the outside of the cold compress component 19, and the sealing strip at the second hollowed-out groove 27 is fitted onto the outside of the body 5 of the temperature measuring instrument. This creates an independent and sealed space in the ankle cold acclimatization garment area, further isolating it from external air interference, stabilizing the local low temperature environment, ensuring that the cold energy is concentrated on the affected area, and improving the overall effect of preoperative cold acclimatization garment care.

[0045] like Figure 6 and Figure 7As shown, the first support frame 7 has a first lightweight groove 31, and the second support frame 8 has a second lightweight groove 33 equidistantly spaced, which can reduce the weight of the components and make them easier to deform under external force. The first support frame 7 and the second support frame 8 work together to provide good restraint for the patient's lower leg. Both sides of the second support frame 8 have bends 32, which can stably support the second support frame 8 on top of the first support frame 7, preventing it from falling off after deformation. The second support frame 8 has an arc-shaped structure that bulges downwards, conforming to the contour of the back of the patient's lower leg, further enhancing the restraint effect. The top of the second support frame 8 has a first pad 9 with a rounded outer edge. The pad 9 is made of cotton material, directly contacting the skin, effectively improving comfort. The bottom of the first pad 9 has equidistant protrusions 34 that match the shape of the second lightweight groove 33. Through the corresponding structural engagement, the first pad 9 can be stably installed on the second support frame 8. Figure 8 As shown, the foot support 14 has segmented grooves 37. The shape of the foot support 14 is adapted to the contour of the human heel, allowing the foot support 14 to undergo appropriate deformation under external force, thereby achieving reliable positioning and support for the patient's heel root.

[0046] like Figure 3 , Figure 8 and Figure 9 As shown, a third connecting frame 35 is fixedly connected to the side of the first support frame 7 near the fourth support frame 13. The end of the third connecting frame 35 near the first support frame 7 is S-shaped, and the end near the body of the microenvironment cold-weather clothing care device 4 is straight. A guide part 36 is provided on the side of the third connecting frame 35 away from the first support frame 7. The temperature measuring instrument body 5 can be assembled on one side of the third connecting frame 35 with the help of the guide part 36. The third connecting frame 35 is made of plastic and has excellent deformation ability. During installation and use, the temperature measuring instrument body 5 is first installed in the corresponding position of the third connecting frame 35, and then the patient places their leg on the second support frame 8. The second support frame 8 and the first support frame 7 deform synchronously under pressure, which drives the third connecting frame 35 to move closer to the patient's leg, thereby pushing the temperature measuring instrument body 5 to fit more closely to the patient's skin and ensure the accuracy of the temperature detection data.

[0047] like Figure 5As shown, a second connecting frame 20 is installed on the temperature measuring instrument body 5. A movable block 21 is fixedly connected to the side of the second connecting frame 20 near the microenvironment cold acclimatization clothing care device body 4. Buffer cavities 23 are provided on both sides of the movable block 21. A movable groove 22 that matches the shape of the movable block 21 is opened on the side of the microenvironment cold acclimatization clothing care device body 4 near the temperature measuring instrument body 5, so that the microenvironment cold acclimatization clothing care device body 4 and the temperature measuring instrument body 5 form a sliding connection and always maintain the same horizontal position. When the skin temperature is detected to exceed the preset safety threshold and the system determines that the cold stimulation intensity is excessive, it is necessary to urgently separate the microenvironment cold acclimatization clothing care device body 4 from the patient's ankle. The support base 3 is moved by the electric telescopic rod 16, which moves the microenvironment cold acclimatization clothing care device body 4 and the cold compress component 19 away from the ankle, ensuring the safety of the cold acclimatization clothing operation. During this process, the temperature measuring instrument body 5 continues to monitor the skin temperature to ensure uninterrupted data acquisition.

[0048] The working process of the preoperative microenvironment cold acclimatization garment nursing device for ankle joint injuries provided by this invention is as follows:

[0049] In use, first install the main body 4 of the microenvironment cooling garment care device and the main body 5 of the temperature measuring instrument in place. Relying on the third connecting frame 35 with elastic deformation capability, the main body 5 of the temperature measuring instrument is continuously pressed and limited laterally, so that the main body 5 of the temperature measuring instrument can adaptively fit the patient's skin and maintain a stable position. The components are aligned and fixed by using the plug-in structure and sliding fit structure. Check the connection parts such as the slider and the slide groove 17 and the locking structure to ensure that the overall assembly is firm and the movement is smooth. Debug the equipment control system, set the target temperature of the cooling garment, the temperature safety threshold, and the refrigerant flow parameters, complete the data calibration and noise reduction settings for ambient temperature and skin temperature, and confirm that the temperature control and temperature measurement functions can operate normally.

[0050] Then, the foot support and limiting mechanism is deployed, and the posture of each support component is adjusted. The tightening strap, sealing structure, and wrapping components are restored to a relaxed state to ensure that the patient's limb can be placed smoothly. The patient is then guided to place their lower leg and foot in the corresponding support area of ​​the device. The support system, consisting of the second support frame 6, the first support plate frame 7, the second support plate frame 8, the third support frame 11, the second pad 12, and the footrest 14, provides support and limitation for the patient's lower leg root, sole, and heel. Utilizing the elastic deformation characteristics of the plastic components, a semi-wrapped constraint is formed on the lower leg to prevent uncontrolled limb movement. The protective sleeve 10 is then placed on the patient's ankle, using the first adhesive strip 28 and the second adhesive strip... Strip 29 achieves sealing on both sides, and the top opening and closing are completed by zipper 30; then the first tightening strap 24 and the second tightening strap 25 are wrapped around the patient's sole and ankle respectively and glued together, and the tightness is adjusted according to the patient's foot shape, so that the cold compress component 19 and the temperature measuring instrument body 5 fit tightly against the ankle skin; the deformation thrust of the third connecting frame 35 further compresses the temperature measuring instrument body 5 to ensure that the temperature measuring component fits the skin and eliminates air interference; at the same time, the sealing strips at the first hollow groove 26 and the second hollow groove 27 are respectively sleeved on the outside of the cold compress component 19 and the temperature measuring instrument body 5, forming an independent sealed space in the ankle area to stabilize the local low temperature environment.

[0051] When the device is started, the microenvironment cold adaptation garment nursing device body 4 adjusts the refrigerant flow according to preset parameters to carry out cold compress operation, and the temperature measuring instrument body 5 collects the skin temperature of the affected area in real time. The system combines skin temperature, pain score, and ankle circumference changes to comprehensively judge the patient's condition, dynamically adjust the intensity of cold stimulation, and issue nursing reminders in a timely manner. During operation, various data are continuously monitored. If the temperature exceeds the safe threshold, the patient feels uncomfortable, or the equipment malfunctions, an emergency operation is immediately initiated: the electric telescopic rod 16 drives the support base 3 to move as a whole, moving the microenvironment cold adaptation garment nursing device body 4 and the cold compress component 19 away from the patient's ankle, and the cold compress is terminated immediately. During this stage, the temperature measuring instrument body 5 continues to monitor the temperature to ensure safe use throughout the process.

[0052] After completing the cold adaptation training, first control the main body 4 of the microenvironment cold adaptation nursing device to stop cooling, then operate the electric telescopic rod 16 to completely remove the main body 4 of the microenvironment cold adaptation nursing device from the ankle area; then untie the first tightening strap 24, the second tightening strap 25 and the zipper 30 in sequence, remove the ankle sleeve 10, assist the patient to move the foot and lower leg, and finally turn off the power of the device, and organize and store the various parts of the device.

[0053] In the above scheme, the device relies on a structural design that combines cold compress, temperature measurement, intelligent control and support limitation to achieve standardized cold acclimatization care for the ankle area. The device works in collaboration with the microenvironment cold acclimatization care device body 4 and the temperature detection component, and comprehensively assesses the patient's condition by combining multi-dimensional vital signs data. With deformable support, sealing protection and adjustable fixation structure, it can stably create a local low temperature environment, and ensure safety and comfort when wearing. The overall operation is simple, adaptable to different foot types, and can effectively complete preoperative cold acclimatization training.

[0054] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
