Description

Technical Field

[0001] This invention relates to the field of medical ice cap technology, and in particular to a multi-mode independent temperature control system for the head and neck area of ​​a medical ice cap. Background Technology

[0002] A medical ice cap is a physical therapy device used for cold compresses on the head. It typically consists of a cooling substance, various types of outer coverings, and fixation devices. Its outer shell is made of soft materials, offering good durability and comfort. The internal cooling device can be a refrigerant, a cooling chip, or filled with cooling gel, ice packs, etc. By lowering the head temperature through cold compresses, it reduces pain and inflammation. It can constrict blood vessels in the head, reducing blood flow and thus alleviating inflammation and swelling. It can also reduce the sensitivity of nerve endings and slow the transmission speed of pain sensations. Furthermore, it can be used to treat head injuries and trauma, promote wound healing, and prevent and relieve allergic reactions in the head.

[0003] Ice cap technology has evolved through a path from "modular → integrated → intelligent → precise → adjustable," reflecting the deepening clinical needs from basic functionality to high efficiency, comfort, and personalization. However, this evolution has also revealed the following problems: 1) Insufficient cooling effectiveness: Traditional devices often lack flexible temperature control modes, making it impossible to personalize settings for different patients. 2) Incomplete data monitoring: Many existing devices do not support real-time monitoring of multiple physiological parameters, limiting the basis for clinical decision-making, and lack independent temperature control for the head and neck zones based on multi-modal physiological signal feedback. 3) Low flexibility: Most ice caps use a fixed, integrated structure. Even advanced intelligent temperature control systems are tightly wound concentric units with interconnected tubing, unable to be flexibly reconfigured to adapt to rapidly changing clinical scenarios.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 As shown, the present invention provides a multi-mode independent temperature control system for the head and neck area of ​​a medical ice cap, including a medical ice cap and an ice cap temperature control subsystem connected to the medical ice cap.

[0026] I. The medical ice cap includes a head cooling area, a neck cooling area, a microcontroller, a user interface, and an electric valve and pump.

[0027] 1) Head cooling area Used for head cooling and head area temperature monitoring; the head cooling area includes a cooling coil for head cooling and a first temperature sensor for head area temperature monitoring.

[0028] Cooling coils: These coils encircle the entire interior of the head, covering the main top, sides, and back of the skull. Coolant (such as saline solution or a specialized coolant) circulates within the coils for efficient cooling. The flowing coolant is cooled by a refrigeration unit (such as a chiller) before flowing into the coils, thus lowering the head temperature.

[0029] The first temperature sensor is embedded in the head cooling area and tightly integrated with the cooling coil. It monitors the temperature of the head area in real time and feeds the data back to the control system to adjust the temperature and flow rate of the flowing coolant.

[0030] 2) Neck cooling area Used for neck cooling and carotid artery region temperature monitoring; the neck cooling area includes a cooling pad for neck cooling and a second temperature sensor for carotid artery region temperature monitoring.

[0031] Cooling pad: Wraps around the neck, fitting snugly against the carotid artery and spine. Designed for an adjustable fit to enhance sealing. Circulation of coolant lowers neck temperature, helping to reduce pressure on cerebrovascular systems.

[0032] The second temperature sensor is connected to the neck cooling pad and faces the skin surface. It monitors the temperature changes of the neck in real time to prevent tissue damage caused by low temperatures.

[0033] 3) Microcontroller Built into one side of the ice cap, it is easy to maintain and operate, and has an access port. It is used to receive temperature monitoring data, determine the cooling mode, and control the working status of the head cooling area and the neck cooling area.

[0034] 4) User Interface Used for connecting an external monitor and control panel to display and set the temperature, as well as select and switch cooling modes.

[0035] 5) Electric valves and pumps This system is used to regulate the head and neck cooling processes based on control signals from the microcontroller. It is located at the inlet and outlet of the head and neck cooling systems. The flow direction and velocity of the coolant are adjusted according to the control signals to ensure that the coolant can flow quickly and effectively into the corresponding areas under different cooling modes.

[0036] The cooling coil, cooling pad, and temperature sensor are connected via a physical magnetic interface, facilitating quick operation by medical personnel and not obstructing the position of other head measurement devices (such as EEG electrodes). The physical magnetic interface uses neodymium iron boron magnets arranged in a ring, with an attraction force ≥15N. A silicone sealing gasket is provided at the interface to prevent coolant leakage. The magnets are 8mm in diameter and 3mm thick, evenly distributed along the edge of the cooling area at 20mm intervals.

[0037] II. Figure 2 As shown, the ice cap temperature control subsystem includes: 1. A physiological signal acquisition module, used to deploy a near-infrared spectroscopy sensor and electroencephalogram (EEG) monitoring electrodes on a medical ice cap to acquire head data and obtain raw monitoring data; the physiological signal acquisition module includes: 1.1 Head Monitoring Unit This is used to deploy 6 to 8 near-infrared spectral sensors and 16 to 32 electroencephalogram (EEG) monitoring electrodes in the frontal, parietal, or occipital regions of a medical ice cap to obtain a monitoring network. The deployment structure and standardized interface of the monitoring network are designed according to user requirements.

[0038] Near-infrared spectroscopy sensor for the head: Based on the requirements for non-invasive brain oxygenation monitoring, a suitable near-infrared spectroscopy sensor (NIRS) is selected. The wavelength range of 700-1000 nm is chosen to ensure the measurement of HbO and HbR concentration changes. The required number of sensors (e.g., 6-8 sensors) and a reasonable arrangement are determined to ensure coverage of major areas of the cerebral cortex, such as the frontal, parietal, and occipital lobes. The sensors must possess high sensitivity and a wide dynamic range to adapt to different patients' physiological states.

[0039] Electroencephalogram (EEG) monitoring electrodes: Select disposable or reusable electrodes with good conductivity and comfort, ensuring good contact with the scalp. Scalp electrode placement covers key brain regions (such as the frontal and temporal lobes) for real-time monitoring of EEG activity. The number of electrodes is typically chosen to be 16-32 to improve the spatial resolution of the data.

[0040] 1.2 Sensor Calibration Unit The near-infrared spectral sensor was subjected to linear regression analysis using standard solutions of known concentrations of cerebral blood flow and oxygen concentration (oxyhemoglobin concentration 20-80 μmol / L, deoxyhemoglobin concentration 10-40 μmol / L) to calibrate the relationship between the sensor output (measurement error ≤ ±3%) and the actual concentration.

[0041] 1.3 Electrode Verification Unit This device is used to test the signal of the EEG monitoring electrodes on a user, recording EEG data in different states (resting, active, seizure, etc.) to test the electrode signal quality. The electrode signal-to-noise ratio is ≥10dB (meeting clinical EEG monitoring standards). 1.4 Data Acquisition and Setting Unit The sampling frequency, data storage and transmission protocol of the near-infrared spectroscopy sensor and the electroencephalogram monitoring electrode are set. The HL7 medical data transmission protocol is used to collect NIRS light signals and potential difference signals from the head to obtain raw monitoring data.

[0042] Sampling frequency: For example, NIRS can be set to 10 times per second, and EEG can be set to 256Hz.

[0044] 2.2 Brain Oxygen Calculation Unit This is used to calculate the dynamic index of hemoglobin based on the standard optical signal using Beer-Lambert's law and the dual-wavelength method, to obtain the local brain oxygen saturation; the local brain oxygen saturation includes the concentration of oxyhemoglobin and the concentration of deoxyhemoglobin.

[0045] Dual-wavelength method: Using two near-infrared bands, 730nm and 850nm, and combining the Beer-Lambert law, the concentrations of oxygenated and deoxygenated hemoglobin are calculated.

[0046] 2.3 Electroencephalogram (EEG) Monitoring Unit Based on the standard potential difference signal, spectral analysis (frequency range 0.5-30Hz) is performed using Fast Fourier Transform to obtain the frequency domain signal. A threshold method (abnormal waveform amplitude ≥75μV) is used to identify obvious abnormal waveforms, and the burst suppression ratio (suppression period duration / total monitoring duration) is calculated to obtain the potential difference signal characteristics. These characteristics include the epileptic discharge frequency and the duration of the epileptic discharge.

[0047] Burst suppression ratio: The ratio of the duration of burst waves to the duration of suppression waves in an electroencephalogram (EEG), used to assess the degree of abnormality in brain electrical activity.

[0048] 3. A zoned temperature control execution module, used to define multiple cooling modes and, based on local brain oxygen saturation and potential difference signal characteristics, to select cooling modes, adjust cooling, and monitor and alarm temperatures; the zoned temperature control execution module includes: 3.1 Pattern Definition Unit like Figure 3As shown, this is used to define the first cooling mode, the second cooling mode, the third cooling mode, and the selection logic for each cooling mode. The first cooling mode is used to determine whether the oxyhemoglobin concentration is below 50% (based on a clinical cerebral ischemia warning threshold). If so, the head cooling area of ​​the medical ice cap is activated, with a target temperature of 32-34℃ and a target cooling rate of 0.5-1℃ / min. The second cooling mode is used to detect whether the potential difference signal characteristics meet the abnormal conditions: epileptic discharge frequency ≥ 1 time / minute and single discharge duration ≥ 500 seconds. If the target temperature is 33-35℃ and the target cooling rate is 0.3-0.8℃ / min, then the third cooling mode is used to determine whether the oxyhemoglobin concentration is less than 50% and whether the potential difference signal characteristic meets the above abnormal conditions. If so, then the head cooling area and neck cooling area of ​​the medical ice cap are activated, with a target head temperature of 32-34℃ and a cooling rate of 0.5-1℃ / min, and a target neck temperature of 33-35℃ and a cooling rate of 0.3-0.8℃ / min.

[0049] 3.2 Cooling Activation Unit Based on the selected cooling mode, the microcontroller sends cooling commands to the corresponding cooling area, collects the cooling rate and current temperature of the corresponding cooling area through a temperature sensor, obtains feedback data, and transmits the feedback data through a user interface.

[0050] 3.3 Cooling Adjustment Unit This is used to set a target temperature and a target cooling amount based on the cooling rate and the current temperature, and to perform temperature control on the corresponding cooling area using a PID control algorithm based on the target temperature and the target cooling amount.

[0051] The PID control algorithm parameters are set as follows: proportional coefficient Kp = 2.5-4.0, integral time Ti = 0.5-1.2s, derivative time Td = 0.1-0.3s; the temperature control accuracy is ±0.3℃ by dynamically adjusting the parameters based on the real-time collected cooling rate and current temperature.

[0052] 3.4 Monitoring and Alarm Unit It is used to monitor whether the current temperature is below 30℃. If so, it will trigger an alarm through the user interface and display the cooling status, temperature changes and current cooling mode in real time.

[0053] When the temperature of any cooling zone drops below 30°C, a Level 1 alarm (audio-visual alarm + interface pop-up) is triggered, and the cooling rate is automatically reduced by 50%. When the temperature remains below 28°C for more than 30 seconds, a Level 2 alarm (continuous audio-visual alarm + cooling circuit cut-off) is triggered, and an emergency notification is sent to the medical terminal through the transmission and visualization module.

[0056] Therefore, this invention provides a multi-mode independent temperature control system for the head and neck area of ​​a medical ice cap. By integrating multiple modules, it achieves personalized cooling and real-time monitoring of physiological data, significantly improving the safety, effectiveness, and flexibility of clinical treatment, optimizing patient comfort, and meeting the needs of modern medicine.
