[0001] The invention belongs to the technical field of orthopedic nursing, and specifically relates to a circulating cold compress device and a control system for bone injury nursing. Background Art

[0002] After a fracture, the patient's injured part will experience obvious swelling, pain and inflammation. These physiological reactions not only increase the patient's pain, but may also affect the healing process of the fracture. Cold compress, as an effective physical therapy, can quickly reduce the temperature of the injured part, promote capillary contraction, reduce local congestion and blood flow, and thus effectively reduce swelling and pain. At the same time, cold compress can also reduce the sensitivity of nerve endings, relieve muscle spasms, and provide a relatively stable recovery environment for the fracture site.

[0003] In actual clinical use, continuous ice compresses on fracture patients will cause secondary reactions, so patients need to be given intermittent ice compresses. However, frequent intermittent ice compresses often lead to untimely removal and replacement of ice packs, and increase the care burden of accompanying personnel. At the same time, since the injured parts of patients are different, such as wrists, humerus and other parts, the ice compress device needs to meet the requirements of ice compresses of different sizes.

[0004] Therefore, it is necessary to provide an ice compress device that can achieve intermittent ice compress and can adjust the size. Summary of the invention

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Example 1

[0039] like Figure 1-7 As shown, the adjustment mechanism 3 includes a rotating ring 301, a connecting rod 302, a sliding groove 303, a gear 304, a slider 305, a motor 306, a base 307, a sealing ring 308, and a shell 1; a hole is opened in the middle of the base 307 and a sealing ring 308 is arranged, a motor 306 is arranged next to the sealing ring 308 on the base 307, a shell 1 is sleeved on the outside of the base 307, four sliding grooves 303 are arranged in an array on the base 307 to install the slider 305, and connecting rods 302 are respectively arranged to rotatably connect the slider 305; the other end of the connecting rod 302 is respectively rotatably connected to the rotating ring 301; the output shaft of the motor 306 is connected to the gear 304; a hole is opened in the middle of the rotating ring 301 and an internal gear is arranged on one side 304 meshing gear 304; a cavity is arranged on the base 307, and a battery pack 309, a timer 310, and a microcontroller 311 are arranged in the cavity; the sealing ring 308 passes through the inner hole of the rotating ring 301 and penetrates the shell 1; the cold compress plate 2 includes a cold compress rod 202, a cold compress shell 203, a semiconductor cooling sheet 204, and a heat sink; an L-shaped cold compress rod 202 is arranged at one end of the cold compress shell 203, and the cold compress shell 203 is hollow and is provided with a semiconductor cooling sheet 204; a heat sink is arranged on the semiconductor cooling sheet 204; the end of the L-shaped cold compress rod 202 is detachably connected to a slider 305; the cold compress shell 203 is semicircular, and a cold compress pad 201 is arranged on the outer concave surface of the cold compress shell 203;

[0040] When the device is in use: put the device on the fracture site of the patient, set the cold compress time, interval and cold compress temperature, start the motor 306 to rotate, the motor 306 rotates to drive the gear 304 to rotate, the gear 304 rotates to drive the rotating ring 301 meshed therewith to rotate, the rotating ring 301 rotates to drive the connecting rods 302 on the four corners to rotate, due to the limit of the slide groove 303, the connecting rod 302 pushes the slider 305 to slide along the slide groove 303, so that the slider 305 drives the cold compress plate 2 to slide, and releases the switch after adjusting to the appropriate position, so as to adjust the distance between the cold compress plates 2 to adapt to the cold compress of different fracture sites of different patients; it solves the problem that the ice compress device in the prior art needs to meet the requirements of ice compressing sites of different sizes;

[0041] In this embodiment, the cold compress plate 2 and the slider 305 are detachably connected, and the cold compress plate 2 can be replaced as needed in actual use; and the motor 306 is set to be inching control to adapt to accurately adjust the spacing of the cold compress plate 2 and ensure the safety of the device during use;

[0042] In this embodiment, since the injured parts of the patients are different, such as the wrist, humerus, etc., the ice compress devices of the prior art often cannot adapt well to parts of different sizes. The adjustment mechanism 3, through the coordinated work of the rotating ring 301, the connecting rod 302, the slide 303, the gear 304, the slider 305 and other components, allows the distance between the cold compress plates 2 to be adjusted as needed, so that it can fit the injured parts of different sizes.

[0043] Example 2

[0044] like Figure 8 As shown, the intermittent cold compress control method of the circulating cold compress device for bone injury care comprises:

[0045] S1: The microcontroller 311 reads the cold compress time, interval and other parameters set by the user through the input device, and stores these parameters in the internal memory;

[0046] S2: According to the time parameters set by the user, the microcontroller 311 configures the timer 310 circuit to generate an accurate time reference signal;

[0047] S3: The timer starts counting, and when the cold compress time is reached, an interrupt signal is sent to the microcontroller 311; the temperature sensor 205 continuously senses the temperature of the cold compress area and converts it into an electrical signal and transmits it to the microcontroller 311;

[0048] S4: After receiving the interrupt signal, the microcontroller 311 turns off the power supply of the semiconductor refrigeration chip and starts the interval waiting timer 310. During the interval, the microcontroller 311 continues to read the value of the temperature sensor 205 to ensure that the temperature is within a safe range;

[0049] S5: When the interval waiting time ends, the timer 310 sends an interrupt signal to the microcontroller 311 again. After receiving the interrupt signal, the microcontroller 311 restarts the power supply of the semiconductor refrigeration plate and starts the next cold compress cycle.

[0050] In this embodiment, the microcontroller 311 is responsible for receiving the setting parameters input by the user, including the cold compress time, interval and cold compress temperature, and controlling the working state of other components according to these parameters, and executing the preset program logic, including starting and stopping the cold compress cycle, monitoring the output of the temperature sensor 205 and responding accordingly; by accurately controlling the time and interval of the cold compress, the intermittent cold compress control system can ensure that the cold compress treatment is carried out within the most effective time, thereby improving the treatment effect. Long-term continuous cold compress may cause excessive cooling of local tissues, causing discomfort or other complications. The intermittent cold compress control system avoids this situation by timing the cold compress cycle;

[0051] The timer 310 accurately measures time to ensure accurate execution of the cold compress time and interval, and sends an interrupt signal to the microcontroller 311 when the preset time is reached, and works in conjunction with the microcontroller 311 to ensure accurate synchronization of the cold compress and interval cycles to avoid confusion or overlap in time;

[0052] The temperature sensor 205 senses the temperature change of the cold compress part in real time and converts it into an electrical signal for the microcontroller 311 to read. When the temperature exceeds the preset safety threshold, the microcontroller 311 controls the operation of the semiconductor cooling sheet to prevent accidents such as skin frostbite.

[0053] In this embodiment, when the control system is actually used, the motor 306 can be controlled to be added to the circulation system as needed. After the cold compress time is completed, the motor 306 is started to reverse so that the cold compress plate 2 is separated from the patient's fracture site, thereby preventing the cold compress plate 2 from being in close contact with the patient's skin for a long time and causing discomfort, allergies and other adverse reactions to the patient. After the interval time is completed, it is started together with the semiconductor refrigeration plate to be close to the skin again for cold compress.

[0054] In summary, the present invention sets an adjustment mechanism 3, and drives the rotating ring 301 meshed with the gear 304 to rotate by rotating the motor 306, so that the connecting rod 302 drives the slider 305 to slide along the slide groove 303, and connects the cold compress plate 2 to the slider 305, so that the slider 305 drives the cold compress plate 2 to slide, thereby achieving the purpose of adjusting the spacing of the cold compress plate 2, so that the device can adapt to the use of cold compresses of different sizes on different parts of the patient; and is equipped with a temperature sensor 205, a timer 310, and a microcontroller 311, which can monitor and adjust the temperature of the cold compress part in real time, ensure that the temperature of the cold compress plate 2 is kept within the set temperature, so as to achieve the best cold compress effect;

[0055] At the same time, an intermittent cold compress control system is designed. Through the precise control of the microcontroller 311, the system can accurately perform cold compress operations according to the time and interval set by the user, ensuring the effectiveness and safety of the cold compress; and the system integrates a temperature sensor 205, which can monitor the temperature of the cold compress area in real time. Once the temperature exceeds the preset safety threshold, the system will automatically turn off the power supply of the semiconductor refrigeration plate to prevent accidents such as skin frostbite; the intermittent cold compress method helps to avoid local discomfort that may be caused by long-term continuous cold compress. Through reasonable cold compress time and interval settings, the patient's comfort can be improved while ensuring the treatment effect; the cold compress time and interval can be freely set according to actual needs to meet the needs of different patients and different treatment stages.
