Abstract
Description
TECHNICAL FIELD
[0001] The application relates to the technical field of orthopedic medical equipment, in particular to a cold compress device for orthopedic ice compress. BACKGROUND
[0002] In orthopedic clinical diagnosis and treatment, ice compress is widely used in scenarios such as fracture, joint sprain, dislocation and postoperative rehabilitation in orthopedics as a classic physical intervention method. Its core function is to stimulate the contraction of local capillaries through low temperature, reduce tissue congestion and edema, relieve pain symptoms, and inhibit inflammatory reactions to create favorable conditions for the repair of affected tissues. However, the current orthopedic ice compress devices used in clinical practice generally have simple design and single function, which cannot meet the needs of precise and personalized clinical treatment. The specific defects can be summarized as follows:
[0003] Firstly, the temperature regulation precision is poor. Traditional devices mainly rely on passive refrigeration methods such as ice bags and ice capsules. The refrigeration liquid or ice blocks continue to rise in temperature during use, and cannot be self-adaptively adjusted according to the real-time temperature of the affected area. This can easily cause skin frostbite due to excessively low initial temperature, or greatly reduce the treatment effect due to insufficient temperature later, especially for elderly patients, children and postoperative weak patients with high skin sensitivity.
[0004] Secondly, the fitting pressure control is rough. The fitting effect of existing devices mainly depends on manual binding and fixing by medical staff, and the pressure size is judged entirely by experience. Excessive pressure can easily compress local blood vessels and nerves, affecting blood circulation and possibly aggravating tissue damage. Insufficient pressure can result in poor fitting of the device to the affected area, low cold energy transfer efficiency, and uneven cold compress, further reducing treatment effectiveness.
[0005] Thirdly, the treatment process lacks effective monitoring and data tracing. Medical staff cannot real-time monitor key parameters such as cold compress temperature, fitting pressure and treatment duration, and can only adjust the treatment plan based on patient subjective feedback, which has a lot of subjectivity and uncertainty. At the same time, there is a lack of record and storage function for treatment data, which is not convenient for subsequent systematic evaluation of treatment effect and is difficult to form a standardized rehabilitation treatment plan.
[0006] Fourthly, the practicality and safety of the device need to be improved. Traditional devices are mostly of one-piece structure, with poor mobility and difficulty in flexible transfer according to treatment scenarios such as hospital rooms, rehabilitation rooms and home care. Although some electric ice compress devices have basic refrigeration functions, they lack emergency protection mechanisms and cannot quickly terminate treatment or release the fitting pressure in the event of power failure or equipment failure, which poses a safety hazard. In addition, the fitting components of existing devices are mostly ordinary cloth or plastic materials, which have poor biocompatibility and can easily cause skin allergies, stuffiness and other problems when used for a long time, affecting patient treatment compliance.
[0007] In conclusion, developing an orthopedic ice pack device that features precise temperature and pressure control, real-time parameter monitoring and data traceability, and is portable, safe, and comfortable has become a pressing technical challenge in the field of orthopedic medical equipment. This is of great significance for improving the level of orthopedic clinical treatment and patient rehabilitation. Summary of the Invention
[0008] The purpose of this invention is to provide a cold compress device for orthopedic ice application, so as to solve the problems of inaccurate temperature and pressure control, inability to track treatment parameters, inconvenience of movement and insufficient safety of existing ice compress devices.
[0009] To achieve the above objectives, the present invention employs the following technical means:
[0010] A cold compress device for orthopedic ice application includes a counterweight base, casters connected to the corners of the bottom of the counterweight base, a mounting plate connected to the top of the counterweight base via multiple sets of connecting rods, a bearing plate connected to the top of the mounting plate via multiple sets of connecting rods, and a counterweight block connected to the top of the counterweight base.
[0011] The top of the mounting plate is connected to a refrigeration and inflation box and a control box. The refrigeration and inflation box contains a liquid storage box and an inflation fan. The top of the liquid storage box is connected to a liquid level sensor and a semiconductor refrigeration module. A cooling fan is connected to the heat dissipation surface of the semiconductor refrigeration module. A liquid storage temperature sensor is embedded in the side of the liquid storage box. The liquid storage box is connected to a miniature pump body through a pipe. An inflation valve is connected to the air outlet of the inflation fan. The control box contains a power module, a data storage module, a wireless data transmission module, and a controller.
[0012] The top of the support plate is connected to an input display and a support tube. An inflatable wrap-around airbag is connected inside the support tube, forming an inflation chamber between the support tube and the inflatable wrap-around airbag. One end of the support tube is connected to an inflation port that is connected to an inflation valve via a pipe. The other end of the support tube is connected to a deflation valve. A display and an emergency stop switch are embedded in the outer wall of the support tube. Multiple pressure sensors and flow guide boxes are embedded in the inner wall of the inflatable wrap-around airbag. An adhesive layer is connected to the outer side of the flow guide box, and a flexible temperature sensor is embedded in the adhesive layer. Multiple flow guide boxes are connected in series. The flow guide box at one end of the series is connected to a micro pump via a pipe, and the flow guide box at the other end of the series is connected to a liquid storage box via a pipe.
[0013] The liquid level sensor, liquid storage temperature sensor, semiconductor refrigeration module, cooling fan, miniature pump, inflation fan, inflation valve, data storage module, wireless data transmission module, controller, input display, display, pressure sensor, and flexible temperature sensor are all connected to the power module, which is connected to an external power source.
[0014] Preferably, the top of the counterweight chassis is provided with a mounting groove, and the counterweight block is inserted into the mounting groove.
[0015] Preferably, the top of the mounting plate is provided with a cable storage groove for storing connecting pipes.
[0016] Preferably, the inner wall of the refrigeration and inflation box is connected with a sound insulation pad.
[0017] Preferably, the side of the support plate is connected to a handle.
[0018] Preferably, the support plate has a through groove for passing through the connecting pipe; the top of the support plate has a placement groove for storing the support pipe.
[0019] Preferably, a buffer pad is connected inside the placement slot.
[0020] Preferably, a lifting strap is connected to the side of the supporting tube.
[0021] Preferably, the vent valve and the emergency stop switch are both mechanical structures.
[0022] Preferably, the bonding layer is a medical-grade silicone product with an anti-slip texture on its surface; the bonding layer has multiple sets of breathable holes.
[0023] The present invention has the following beneficial effects:
[0024] 1. Achieving precise adaptive cold compresses, enhancing treatment safety and effectiveness: This device uses a flexible temperature sensor to collect the skin surface temperature of the affected area in real time, and a pressure sensor to simultaneously monitor the contact pressure of the inflatable airbag. Data from both sensors is directly fed back to the controller, forming a closed-loop control system. The controller can adjust the cooling power of the semiconductor cooling module in real time according to preset parameters, avoiding over-freezing or insufficient temperature. Simultaneously, it precisely controls the start / stop of the inflation fan and the status of the inflation valve, ensuring the contact pressure remains within a comfortable and effective range. This overcomes the shortcomings of traditional devices' coarse temperature and pressure control, significantly improving the precision and safety of cold compress therapy and ensuring stable and reliable treatment results.
[0025] 2. Achieving Data-Driven Treatment Management for Efficacy Assessment and Remote Monitoring: The device's data storage module comprehensively records key parameter curves such as temperature, pressure, and time throughout the entire cold compress process. The wireless data transmission module uploads this data to the cloud or mobile terminal in real time, enabling digital traceability of the treatment process. Medical staff can remotely view patient treatment compliance and parameter changes through the terminal, facilitating accurate efficacy assessment and the development of personalized rehabilitation plans. It also provides data support for digital ward management and remote guidance for home rehabilitation, solving the problem of traditional devices lacking monitoring and data traceability functions, and improving the standardization and intelligence of medical services.
[0026] 3. Enhanced practicality and mobility: The combination of casters at the bottom and handles on the support plate allows for flexible transfer to various treatment scenarios such as wards, rehabilitation rooms, and homes, meeting diverse usage needs. The counterweight chassis and detachable counterweights allow for weight adjustment based on actual requirements, improving stability and preventing tipping risks. Furthermore, the rational layout of cable trays, wiring channels, and placement slots enables neat and convenient storage of pipes and support tubes, simplifying operation and maintenance processes and resolving the problems of inconvenient movement and cluttered structure associated with traditional devices.
[0027] 4. Enhanced safety and improved patient comfort and compliance: The device is equipped with a mechanically designed deflation valve and emergency stop switch. In case of sudden power outages, equipment malfunctions, or patient discomfort, the airbag pressure can be quickly released manually or the operation of core components can be cut off, providing dual safety protection and reducing usage risks. The adhesive layer is made of medical-grade silicone, which combines good biocompatibility and softness. The anti-slip texture on the surface improves the stability of the fit, and multiple sets of vents enhance local breathability, effectively reducing discomfort such as skin stuffiness and allergies. Combined with the low-noise design during device operation, this significantly improves patient comfort and thus enhances treatment compliance. Attached Figure Description

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The top of the mounting plate 6 is connected to a refrigeration and inflation box 8 and a control box 17. The refrigeration and inflation box 8 is connected to a liquid storage box 10 and an inflation fan 15. The top of the liquid storage box 10 is connected to a liquid level sensor 9 and a semiconductor refrigeration module 12.

The control box 17 is connected to a power module 18, a data storage module 19, a wireless data transmission module 20, and a controller 21.
[0038] The top of the support plate 22 is connected to an input display 24 and a support tube 26. An inflatable wrapping airbag 27 is connected inside the support tube 26, and an inflation chamber is formed between the support tube 26 and the inflatable wrapping airbag 27. One end of the support tube 26 is connected to an inflation interface 28 that is connected to an inflation valve 16 through a pipe. The other end of the support tube 26 is connected to a deflation valve 29. A display 30 and an emergency stop switch 31 are embedded in the outer wall of the support tube 26. Multiple pressure sensors 32 and flow guide boxes 34 are embedded in the inner wall of the inflatable wrapping airbag 27. An adhesive layer 36 is connected to the outer side of the flow guide box 34. A flexible temperature sensor 35 is embedded in the adhesive layer 36. Multiple flow guide boxes 34 are connected in series. The flow guide box 34 at one end of the series is connected to the micro pump body 14 through a pipe, and the flow guide box 34 at the other end of the series is connected to the liquid storage box 10 through a pipe.
[0039] Liquid level sensor 9, liquid storage temperature sensor 11, semiconductor refrigeration module 12, cooling fan 13, micro pump body 14, inflation fan 15, inflation valve 16, data storage module 19, data wireless transmission module 20, controller 21, input display 24, display 30, pressure sensor 32, and flexible temperature sensor 35 are all connected to power module 18, which is connected to an external power source.

[0040] The top of the counterweight chassis 1 is provided with a mounting groove 4, and the counterweight block 5 is inserted into the mounting groove 4, which facilitates the disassembly and replacement of the counterweight block 5. The counterweight can be adjusted according to the actual use requirements of the device to improve the stability of the device.
[0041] The top of the mounting plate 6 is provided with a cable storage groove 7 for storing connecting pipes, which can neatly store the connecting pipes inside the device, avoid pipes from being tangled and messy, improve the neatness of the internal structure of the device, and facilitate later maintenance.
[0042] The inner wall of the cooling and inflation box 8 is connected with a sound insulation pad, which can effectively reduce the noise generated by components such as the cooling fan 13 and the inflation fan 15 when they are working, improve the quietness of the device during use, and improve the treatment environment for patients.
[0043] The side of the support plate 22 is connected to a handle 23, which makes it easy for medical staff to push the device to move. Together with the casters 2 at the bottom of the counterweight chassis 1, the device’s mobility is improved, and the device can be easily transferred to different wards or treatment areas.

[0047] Both the vent valve 29 and the emergency stop switch 31 are mechanical structures. The mechanical vent valve 29 and the emergency stop switch 31 can work without electric drive. Even in the event of a power outage or other emergencies, the gas inside the inflatable airbag 27 can be released by manually operating the vent valve 29, or the operation of the core components of the device can be cut off by the emergency stop switch 31, thereby improving the safety of the device.
[0048] The adhesive layer 36 is made of medical-grade silicone with an anti-slip texture on its surface. The adhesive layer 36 has multiple sets of ventilation holes 37. The medical-grade silicone material has good biocompatibility and softness, providing high comfort when applied to the patient's affected area. The anti-slip texture can improve the stability of the adhesive layer 36 in contact with the skin of the affected area and prevent the device from shifting during cold compresses. The ventilation holes 37 can enhance the breathability of the application area, reduce the feeling of stuffiness on the skin, and reduce the risk of skin allergies or bacterial growth.
[0049] Working principle
[0050] This device operates based on the core logic of "precise sensing - closed-loop control - data traceability". The various structures work together to complete orthopedic ice pack and cold compress treatment. The specific working principle is as follows:
[0051] I. Equipment Preparation and Parameter Setting Stage
[0052] 1. Movement and Fixing: The device can be pushed to the patient treatment area by using the handle 23 on the side of the support plate 22 and the casters 2 at the bottom of the counterweight chassis 1. Locking the casters 2 ensures the stability of the device. If the environment is uneven, the weight of the device can be adjusted by using the counterweight block 5 in the mounting groove 4 at the top of the counterweight chassis 1 to further improve stability.
[0053] 2. Consumables replenishment and component inspection: Open the refrigerant charging box 8 and add sufficient refrigerant to the liquid storage box 10. The liquid level sensor 9 on the top of the liquid storage box 10 monitors the liquid level in real time. If the liquid level is lower than the set threshold, an alarm will be issued through the input display 24. At the same time, check whether all connecting pipes (including the connecting pipes between the liquid storage box 10 and the micro pump body 14 and the flow guide box 34, and the connecting pipes between the air blower 15 and the air valve 16 and the air interface 28) are unobstructed and ensure that there are no leaks.
[0054] 3. Parameter setting: Medical staff can set parameters such as cold compress temperature, application pressure, and cold compress duration through the input display 24 on the carrier plate 22. The parameter information is transmitted to the controller 21 in the control box 17 in real time. The controller 21 simultaneously sends the parameters to the display 30 on the outer wall of the carrier tube 26 for easy viewing by patients and medical staff.
[0055] II. Inflation and Fitting Stage (Achieving Precise Pressure Fit)
[0056] 1. Inflation of the airbag: The controller 21 issues a command to start the inflation fan 15 in the refrigeration inflation box 8 and open the inflation valve 16 at the same time; the gas enters the inflation chamber between the carrier tube 26 and the inflatable airbag 27 through the inflation port 28 at one end of the carrier tube 26 via the pipeline, pushing the inflatable airbag 27 to expand.
[0057] 2. Pressure closed-loop control: During inflation, multiple pressure sensors 32 on the inner wall of the inflatable airbag 27 collect the bonding pressure data in real time and continuously feed it back to the controller 21. When the pressure reaches the threshold set by the input display 24, the controller 21 immediately controls the inflation fan 15 to stop working and closes the inflation valve 16 to complete the inflation bonding and ensure that the pressure is always within a comfortable and effective range.
[0058] III. Cooling Cycle and Cold Compress Implementation Stage (Achieving Precise Temperature Control)
[0059] 1. Cooling Start-up: The controller 21 sends a cooling command to the semiconductor cooling module 12 in the cooling gas charging box 8. The semiconductor cooling module 12 begins to cool the refrigerant in the liquid storage box 10. At the same time, the cooling fan 13 on the heat dissipation surface of the semiconductor cooling module 12 starts synchronously to quickly dissipate the heat generated during the cooling process, thereby improving the cooling efficiency and service life of the semiconductor cooling module 12.
[0060] 2. Cooling liquid circulation: The cooling liquid temperature sensor 11 on the side of the liquid storage box 10 monitors the cooling liquid temperature in real time. When the temperature drops to the set value, the controller 21 starts the micro pump 14. The micro pump 14 pumps the cooled cooling liquid into the series-connected flow guide box 34. When the cooling liquid flows in the flow guide box 34, it transfers cold energy to the patient's affected area through the adhesive layer 36 on the outer side of the flow guide box 34 to achieve cold compress treatment. After completing the heat exchange, the cooling liquid returns to the liquid storage box 10 through the pipe of the flow guide box 34 at the other end of the series connection, forming a closed loop circulation.
[0061] 3. Temperature closed-loop control: During the cold compress process, the flexible temperature sensor 35 in the adhesive layer 36 collects the surface temperature of the affected skin in real time and feeds the data back to the controller 21. If the temperature is lower than the set minimum value, the controller 21 reduces the cooling power of the semiconductor cooling module 12 or stops cooling. If the temperature is higher than the set maximum value, the controller 21 increases the power of the semiconductor cooling module 12 to ensure that the temperature of the affected area is stable within the set range and avoids frostbite.
[0062] IV. Data Monitoring and Transmission Stage
[0063] 1. Data Acquisition and Storage: Throughout the entire cooling process, the controller 21 receives real-time monitoring data from the liquid level sensor 9, the liquid storage temperature sensor 11, the pressure sensor 32, and the flexible temperature sensor 35. It also records information such as cooling duration and inflation pressure change curves, and transmits this data to the data storage module 19 in the control box 17 for complete storage, facilitating subsequent traceability.
[0064] 2. Remote data transmission: The wireless data transmission module 20 uploads the parameters in the data storage module 19 to the cloud or the mobile terminal of medical staff in real time to realize remote monitoring; medical staff can view the patient's treatment status in real time through the terminal without on-site duty, thus improving the efficiency of medical management.
[0065] V. Treatment Completion and Emergency Management Phase
[0066] 1. Normal termination: When the cold compress duration reaches the set value, the controller 21 issues a command to stop the micro pump 14, semiconductor cooling module 12, and cooling fan 13 in sequence; medical staff can open the air release valve 29 mechanical structure at the other end of the carrier tube 26 without electricity to release the gas in the inflation chamber, causing the inflatable airbag 27 to contract and detach from the affected area; then the carrier tube 26 is placed into the placement slot 38 on the top of the carrier plate 22 for storage, and the buffer pad 39 in the placement slot 38 can prevent the carrier tube 26 from being damaged.
[0067] 2. Emergency handling: If the patient experiences discomfort or the device malfunctions during treatment, medical staff or the patient can directly press the emergency stop switch 31 (mechanical structure, no electricity required) on the carrier tube 26; after receiving the emergency stop signal, the controller 21 immediately cuts off the power supply to the core components such as the semiconductor cooling module 12, the micro pump 14, and the air inflator 15, and at the same time, it can quickly release air through the air release valve 29 to ensure the patient's safety.
[0068] Example 1: Cold compress treatment after adult upper limb radius fracture surgery
[0069] 1. Scene adaptation: For adult patients after radius fracture surgery, a 35cm long support tube 26 is selected to match the size of the upper limb forearm; the adhesive layer 36 is made of 2mm thick medical silicone material with a dense anti-slip texture on the surface to enhance the stability of the fit with the forearm skin; at the same time, the 4 sets of pressure sensors 32 and 2 sets of flexible temperature sensors 35 inside the inflatable wrapping airbag 27 are evenly distributed to ensure coverage of the fracture site and surrounding tissues.
[0070] 2. Parameter settings: Set the parameters via the input display 24: cold compress temperature 8℃, application pressure 0.04MPa, cold compress duration 20 minutes.
[0071] 3. Operation Process: Following the aforementioned working principle, the device is moved and fixed, and the storage box 10 is filled with refrigerant (a mixture of medical alcohol and water, in a 1:1 ratio). After the device is started, the inflation fan 15 inflates the inflation chamber through the inflation port 28. The pressure sensor 32 provides real-time feedback of pressure data, and inflation stops when the pressure reaches 0.04 MPa. The semiconductor cooling module 12 starts cooling. When the storage liquid temperature sensor 11 detects that the refrigerant has dropped to 8°C, the micro pump 14 starts, and the refrigerant circulates in the guide box 34, transferring the cooling energy to the affected area through the adhesive layer 36. The flexible temperature sensor 35 monitors the skin temperature in real time. If the temperature is below 6°C, the controller 21 reduces the power of the semiconductor cooling module 12; if the temperature is above 10°C, the power is increased.
[0072] 4. Data and Emergency: The data storage module 19 records the temperature and pressure curves throughout the process, and the data wireless transmission module 20 uploads the data to the medical station terminal; if the patient experiences numbness in the forearm during treatment, pressing the emergency stop switch 31 will immediately cut off the power to the core components, open the vent valve 29 to release the pressure, and terminate the treatment.
[0073] Example 2
[0074] Cold compress treatment for acute knee sprains in adults
[0075] 1. Scene adaptation: For adult patients with acute knee sprains, a 50cm long, curved support tube 26 is selected to fit the contour of the knee joint; the bonding layer 36 has more ventilation holes 37 (2 per square centimeter) to improve the breathability of the skin around the knee joint; two sets of pressure sensors 32 are added to the inside of the inflatable wrapping airbag 27 to monitor the bonding pressure on the inside and outside of the knee joint.
[0076] 2. Parameter settings: Set parameters via the input display 24: cold compress temperature 6℃, application pressure 0.05MPa, cold compress duration 15 minutes (once every hour during the acute phase, for a total of 3 times).
[0077] 3. Operation process: The device is moved to the bedside, and its position is adjusted by the handle 23, and the casters 2 are locked; cooling liquid (a mixture of physiological saline and ethylene glycol in a ratio of 2:1) is added to the reservoir 10; after startup, the inflatable airbag 27 expands and fits the knee joint, and the cooling cycle starts after the pressure stabilizes; because the knee joint is rich in blood vessels, the flexible temperature sensor 35 adjusts the temperature in real time to avoid excessive cooling; the data of each treatment is automatically stored and uploaded, and medical staff can view the parameters through a mobile terminal to judge the treatment effect.
[0078] 4. Special handling: During the second treatment, the liquid level sensor 9 detected insufficient refrigerant and issued an alarm on the display 24. Medical staff replenished the liquid in time and continued the treatment.
[0079] Example 3
[0080] Cold compress treatment for soft tissue contusions of the forearm in children
[0081] 1. Scene adaptation: For soft tissue contusions of the forearm in children aged 6, a small carrier tube 26 with a length of 25cm is selected. The adhesive layer 36 is made of softer medical silicone (Shore hardness 20A) to reduce irritation to children's delicate skin. The flexible temperature sensor 35 uses a miniature probe to avoid compressing the skin. The thickness of the buffer pad 39 in the placement slot 38 is increased to 1cm to better protect the small carrier tube 26 when stored.
[0082] 2. Parameter settings: Considering the sensitivity of children's skin, the parameters are set as follows: cold compress temperature 10℃, application pressure 0.03MPa, and cold compress duration 10 minutes.
[0083] 3. Operation process: After the device is moved, the weight of the device is adjusted by the counterweight 5 to prevent the device from tipping over due to excessive weight; a small amount of refrigerant is added (1 / 2 of the capacity of the reservoir 10), and the liquid level sensor 9 monitors it normally; after startup, the inflation proceeds slowly, and the pressure sensor 32 precisely controls the pressure to not exceed 0.03MPa; during the cooling process, the power of the semiconductor cooling module 12 is reduced, and the cooling fan 13 selects a low speed mode to reduce the operating noise of the device; during the treatment process, the display 30 displays the temperature and pressure in real time for the convenience of parents to observe.
[0084] 4. Safety Guarantee: After the treatment is completed, the controller 21 will automatically emit a prompt sound, and the medical staff will open the vent valve 29 to slowly release the air, so as to avoid the sudden drop in pressure causing discomfort to the child; after the treatment data is stored, it can be sent to the parents' mobile phone through the data wireless transmission module 20 for reference during home care.
