Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent nursing equipment, and in particular relates to an intelligent neck support device for wound care after thyroid surgery. Background Art

[0002] After thyroid surgery, the patient's wound should be kept clean and dry to avoid infection. At the same time, the range of motion of the neck should be limited to effectively reduce wound pain and speed up the healing process of the wound. After thyroid surgery, medical staff often need to apply cold compresses to the wound of thyroid patients to effectively stimulate the contraction of capillaries at the wound site, slow down blood circulation, thereby reducing wound tissue fluid exudation, reducing wound swelling, and weakening wound pain, so as to help the wound recover quickly after thyroid surgery.

[0003] Traditional cold compress care often uses a textile-wrapped ice bag to gently apply to the wound. This method has the problem of difficult to accurately control the cold compress temperature and time. Low cold compress temperature and long cold compress time will cause discomfort from low temperature stimulation, and even damage the skin and surrounding tissues, leading to adverse consequences such as frostbite. The cold compress temperature is not low enough, the cold compress time is short, and the cold compress cannot fully play its role, which seriously affects the effect of the cold compress. Because the cold compress requires the ice bag to be lightly applied to the wound, even if the wound has tissue fluid extravasation during the cold compress process, it cannot be discovered and treated in time, thereby increasing the possibility of wound infection. In addition, the entire cold compress process usually requires the patient or the caregiver to hold the ice bag, which increases the inconvenience of care.

[0004] When there is no extravasation of tissue fluid in the wound after thyroid surgery and the swelling begins to subside, the wound can be treated with hot compresses to effectively promote capillary dilation and accelerate blood circulation, which is conducive to accelerating the absorption of hematoma. Traditional hot compress care often uses a method of soaking textiles in hot water, wringing them out, and then gently applying them to the wound. Like the traditional cold compress care process, traditional hot compress care also has the problem of difficult to accurately control the hot compress temperature and time. If the hot compress temperature is high and the hot compress time is long, it will produce discomfort caused by high temperature stimulation, and may even cause damage to the skin and surrounding tissues, leading to adverse consequences such as burns. If the hot compress temperature is not high enough and the hot compress time is short, the effect of the hot compress cannot be fully exerted, affecting the effect of the hot compress. In order to effectively solve the above problems, it is urgent to provide a neck care device that can simplify the care process, accelerate the recovery of wounds, have good wearing comfort, and can realize intelligent control of hot and cold compresses. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides an intelligent cervical collar device for wound care after thyroid surgery. The device has a simple structure, low manufacturing cost, high intelligence, and good wearing comfort. It integrates the functions of neck movement restriction, hot and cold compresses, and perception and alarm of tissue fluid extravasation during nursing process. The hot and cold compress functions can be switched according to the different recovery levels of the wearer, which is conducive to significantly shortening the patient's recovery time. At the same time, it can greatly reduce the labor burden of the nursing process.

[0006] In order to achieve the above-mentioned object, the present invention provides an intelligent cervical collar device for wound care after thyroid surgery, comprising a cervical collar body and a power supply control component;

[0007] The neck support body comprises a front neck support, a rear neck support and a temperature adjustment sensing block;

[0008] The front neck support and the rear neck support are connected by a connecting assembly; a mounting hole is provided in the lower area of ​​the front neck support; the temperature regulating sensing block has a cold compress and a hot compress working mode, and the shape and size of the temperature regulating sensing block are adapted to the mounting hole and fixedly installed in the mounting hole;

[0009] The power supply control component is connected to the temperature control sensing block and is used to provide power supply, intelligent control, information display and sound alarm to the temperature control sensing block.

[0010] Furthermore, in order to make the temperature control sensing block have cold compress function, hot compress function and tissue fluid extravasation sensing function at the same time, the temperature control sensing block includes temperature conduction tiles, neck support thermocouples, semiconductor refrigeration sheets, silicone pads and tissue fluid extravasation sensing lines; the neck support thermocouples are fittedly installed on the outer surface of the temperature conduction tiles for real-time temperature signal collection; multiple semiconductor refrigeration sheets are evenly installed on the outer surface of the temperature conduction tiles for synchronously providing cooling and heating functions; the silicone pad is a flat structure with a cavity inside, which is fittedly installed on the inner surface of the temperature conduction tile and is filled with heat conduction liquid alcohol; the tissue fluid extravasation sensing lines are U-shaped and evenly spaced on the inner surface of the silicone pad.

[0011] By installing a neck support thermocouple on the outer surface of the temperature conduction tile, it is convenient to collect the temperature signal of the temperature conduction tile surface in real time, so that the temperature signal can be used as a feedback control signal, and then the cold compress temperature can be accurately controlled to effectively ensure the comfort during the cold compress process. At the same time, the temperature signal can also be used as a feedback control signal, and then the hot compress temperature can be accurately controlled to effectively ensure the comfort during the hot compress process. A silicone pad with a cavity is provided, and the cavity is filled with heat conduction liquid alcohol, which can not only further improve the comfort during wearing, but also use the excellent heat transfer efficiency of alcohol to ensure that the entire hot or cold compress surface can be evenly heated or cooled, which can avoid local overheating or overcooling, and further ensure the effect of hot and cold compress. Installing multiple semiconductor cooling sheets on the outer surface of the temperature conduction tile can conveniently realize the cooling and heating functions on the basis of ensuring that the structure of the temperature control sensing block is as simple as possible. Due to the Peltier effect and the Seebeck effect, when the semiconductor cooling sheet passes through the forward current, the heat inside the semiconductor cooling sheet will be transferred to the outside. When the semiconductor refrigeration chip passes through the reverse current, the heat outside the semiconductor refrigeration chip will be transferred to the inside, thereby realizing two-way heat transfer conveniently. This makes it easy to switch between cold and hot compress functions. Tissue fluid extravasation sensing lines are set at equal intervals in a U-shape on the inner surface of the silicone pad, which can detect tissue fluid extravasation in a timely manner, and then take effective countermeasures in a timely manner, which significantly reduces the possibility of wound infection. In addition, the temperature-adjusting sensing block formed by the temperature-conducting tile, semiconductor refrigeration sheet, silicone pad and tissue fluid extravasation sensing line is light in weight as a whole, and will not cause a large wearing burden during the long-term wearing process of the patient, ensuring the wearing comfort during the recovery process.

One end of the two Velcro on the same side is respectively connected to the two rear fixing buckles, and the other end of the two Velcro on the same side is respectively connected to itself after bypassing the two front fixing buckles.

[0018] Furthermore, in order to improve the comfort during wearing, a plurality of front ventilation holes are evenly opened in the upper area of ​​the front neck support, and a plurality of rear ventilation holes are evenly opened in the upper area of ​​the rear neck support.

[0019] Further, in order to improve the overall intelligence level and ensure the overall reliability and stability, the controller includes a housing, a display screen, a setting button, a switch button, an up button, a down button, a left button, a right button and a control circuit;

[0020] The display screen, setting button and switch button are sequentially embedded and installed on the top plate of the shell from top to bottom; the upper button and the lower button are respectively embedded and installed on the top plate of the shell, and are respectively located on the left and right sides above the button; the left button and the right button are respectively embedded and installed on the top plate of the shell, and are respectively located on the left and right sides below the setting button; the second wiring terminal of the upper button, the second wiring terminal of the lower button, the second wiring terminal of the left button, the second wiring terminal of the right button, and the second wiring terminal of the setting button are all grounded;

[0021] The control circuit includes a power module, an NMOS switch group, a buzzer, a pre-drive module and a main control chip;

[0022] The power module includes a Flyback module and a Buck module, the input end of the Flyback module is used to connect to an external 220V AC power supply, the input end of the Buck module is connected to the output end of the Flyback module through a switch button, and the output end is respectively connected to the power pin of the main control chip, the first terminal of the upper button, the first terminal of the lower button, the first terminal of the left button, the first terminal of the right button, the first terminal of the setting button, and the high potential terminal of the tissue fluid extravasation sensing line;

[0023] The NMOS tube switch group includes NMOS tube 1, NMOS tube 2, NMOS tube 3, NMOS tube 4 and a current sampling resistor, the S pole of NMOS tube 1 is connected to the D pole of NMOS tube 2, the S pole of NMOS tube 3 is connected to the D pole of NMOS tube 4, the D pole of NMOS tube 1 and the D pole of NMOS tube 3 are both connected to the input end of the Buck module, and the S pole of NMOS tube 2 and the S pole of NMOS tube 4 are both grounded through the current sampling resistor; the connection node between NMOS tube 1 and NMOS tube 2 is respectively connected to the positive electrode terminals of multiple semiconductor cooling plates, and the connection node between NMOS tube 3 and NMOS tube 4 is respectively connected to the negative electrode terminals of multiple semiconductor cooling plates;

During the process of cold and hot compress, if tissue fluid flows out of the wound after thyroid surgery, the third amplifier will output a high-level signal. After receiving the high-level signal, the main control chip will control the buzzer to sound an alarm. At the same time, it will send information to the display screen to remind medical staff to deal with the wound in time, which can effectively promote the recovery of the wound after thyroid surgery, reduce the risk of wound infection, and greatly reduce the nursing burden of medical staff and patients.

A mounting hole is provided in the lower area of ​​the front neck support, and a corresponding temperature adjustment sensing block is installed in the mounting hole, and the temperature adjustment sensing block has cold compress and hot compress working modes. In this way, when cold compress care is required for the wound site of the thyroid patient after thyroid surgery, the temperature adjustment sensing block can be operated in the cold compress working mode, so that the capillaries at the wound site can be stimulated to contract and blood circulation can be slowed down by cold compress care, thereby reducing the exudation of wound tissue fluid, effectively reducing wound swelling, weakening wound pain, and allowing the wound to recover quickly after thyroid surgery. At the same time, when there is no extravasation of tissue fluid in the wound after thyroid surgery and the swelling begins to subside, and hot compress treatment is required, the temperature control sensing block can be operated in the hot compress working mode, so as to effectively promote capillary dilation and accelerate blood circulation through hot compress, thereby effectively accelerating the absorption of hematoma. By setting a power supply control component for powering the temperature control sensing block and controlling the working mode time, the cold and hot compress working mode and the corresponding working time of the temperature control sensing block can be intelligently adjusted, thereby avoiding the problem of skin tissue damage caused by too long cold and hot compress time, and at the same time, it can help to improve the wearing comfort. Finally, the use of this device can eliminate the need to separate the neck brace body from the patient during the entire recovery process, that is, the corresponding cold and hot compress auxiliary recovery treatment plan can be implemented according to different recovery stages, avoiding the harm to the patient caused by the unstable factors caused by the multiple separation of the neck brace body from the patient, greatly ensuring the smooth completion of the recovery process and improving the health protection of the patient.

[0027] The device has a simple structure, low manufacturing cost, high intelligence and good wearing comfort. It integrates functions such as neck movement restriction, hot and cold compresses, and perception and alarm of tissue fluid extravasation during nursing. It can switch the hot and cold compress functions according to the different recovery levels of the wearer, which is conducive to significantly shortening the patient's recovery time. At the same time, it can greatly reduce the labor burden of the nursing process. BRIEF DESCRIPTION OF THE DRAWINGS

Temperature regulation: Cooperating with the current sampling and temperature feedback links, the current size is controlled by controlling the switch duty cycle through 4 NMOS tubes, thereby controlling the temperature regulation speed and then realizing precise control of the set temperature. At the same time, the current direction can also be controlled to switch between hot and cold compress modes. If the current value is abnormal, all NMOS tubes can be turned off through the pre-drive module to protect the circuit safety and give a fault information prompt;

[0069] 8. Configuration buttons: Input hot and cold compress mode, temperature, time and other information through the coordination of various buttons;

[0070] 9. Interstitial fluid extravasation perception: The reverse input terminal of the third amplifier is used as a reference voltage point, wherein an adjustable resistor can be connected, so as to use the adjustable resistor to control the sensitivity of interstitial fluid extravasation perception. Increasing the resistance of the adjustable resistor reduces the sensitivity of perception, and vice versa, increases the sensitivity of perception. When there is interstitial fluid extravasation, a high level will appear at the same-direction input terminal of the third amplifier, causing the third amplifier to output a high level; when there is no interstitial fluid extravasation, a low level will appear at the same-direction input terminal of the third amplifier, causing the third amplifier to output a low level.

[0071] In this way, the functions of neck movement restriction, cold compress, hot compress, tissue fluid extravasation sensing and alarm during the nursing process can be integrated into one, and the clock module built into the main control chip can be used to accurately control the temperature and time of cold and hot compress. During the process of cold and hot compress, if tissue fluid flows out of the wound after thyroid surgery, the third amplifier will output a high-level signal. After receiving the high-level signal, the main control chip will control the buzzer to sound an alarm. At the same time, it will send information to the display screen to remind medical staff to deal with the wound in time, which can effectively promote the recovery of the wound after thyroid surgery, reduce the risk of wound infection, and greatly reduce the nursing burden of medical staff and patients.

[0072] In the present invention, the front neck support and the rear neck support are connected by a connecting assembly to form a neck support body suitable for the wearer. In this way, the neck support body can be used to effectively limit the range of motion of the neck, which helps to reduce the pain of the wound and accelerate the healing process of the wound. A mounting hole is provided in the lower area of ​​the front neck support, and a corresponding temperature adjustment sensing block is installed in the mounting hole, and the temperature adjustment sensing block has cold compress and hot compress working modes. In this way, when cold compress care is required for the wound site of the thyroid patient after thyroid surgery, the temperature adjustment sensing block can be operated in the cold compress working mode, so that the capillaries at the wound site can be stimulated to contract and blood circulation can be slowed down by cold compress care, thereby reducing the exudation of wound tissue fluid, effectively reducing wound swelling, weakening wound pain, and allowing the wound to recover quickly after thyroid surgery. At the same time, when there is no extravasation of tissue fluid in the wound after thyroid surgery and the swelling begins to subside, and hot compress treatment is required, the temperature control sensing block can be operated in the hot compress working mode, so as to effectively promote capillary dilation and accelerate blood circulation through hot compress, thereby effectively accelerating the absorption of hematoma. By setting a power supply control component for powering the temperature control sensing block and controlling the working mode time, the cold and hot compress working mode and the corresponding working time of the temperature control sensing block can be intelligently adjusted, thereby avoiding the problem of skin tissue damage caused by too long cold and hot compress time, and at the same time, it can help to improve the wearing comfort. Finally, the use of this device can eliminate the need to separate the neck brace body from the patient during the entire recovery process, that is, the corresponding cold and hot compress auxiliary recovery treatment plan can be implemented according to different recovery stages, avoiding the harm to the patient caused by the unstable factors caused by the multiple separation of the neck brace body from the patient, greatly ensuring the smooth completion of the recovery process and improving the health protection of the patient.

[0073] The device has a simple structure, low manufacturing cost, high intelligence and good wearing comfort. It integrates functions such as neck movement restriction, hot and cold compresses, and perception and alarm of tissue fluid extravasation during nursing. It can switch the hot and cold compress functions according to the different recovery levels of the wearer, which is conducive to significantly shortening the patient's recovery time. At the same time, it can greatly reduce the labor burden of the nursing process.
