Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for accurately regulating the body temperature of a patient undergoing a neurosurgery operation. Background Art

[0002] Neurosurgery is a highly delicate and complex medical operation, and the operation usually takes a long time. During the operation, it is crucial to maintain the patient's body temperature within the normal range, because too high or too low body temperature may have a serious impact on the patient's life safety. Too low body temperature, especially under anesthesia, may lead to metabolic disorders, decreased immunity and slow recovery after surgery, while too high body temperature may cause complications such as tissue damage and bleeding. Therefore, how to accurately and continuously monitor and regulate the patient's body temperature has become a key issue that cannot be ignored during neurosurgery.

[0003] At present, the commonly used temperature control methods in neurosurgery include traditional passive temperature control methods and active temperature control methods. Passive temperature control usually maintains body temperature by laying warm sheets on the operating table or using warm infusion fluids. This method is slow and imprecise, and it is difficult to cope with situations where the patient's body temperature fluctuates greatly. Active temperature control methods use external heating or cooling devices to directly control the temperature of the patient's body surface. Although it can improve the accuracy of temperature control to a certain extent, existing active control devices generally have problems such as slow response speed, uneven temperature distribution, and imprecise control of specific body temperature areas.

[0004] Therefore, in neurosurgery, how to accurately and in real time monitor and regulate the patient's body temperature, especially the fine regulation of the body temperature in different areas during surgery, is the main challenge facing current temperature management technology.

[0022] Figure 2 4 is a flow chart of body temperature data processing in an embodiment of the present invention. DETAILED DESCRIPTION

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The device for precise temperature control of patients during neurosurgery of the present invention aims to ensure that the patient's body temperature is always within the ideal range during the operation through a high-precision temperature monitoring and control system, so as to improve the safety of the operation and reduce postoperative complications. The device integrates multiple modules, covering functions such as temperature monitoring, temperature control, data recording and early warning, and can adjust the control strategy in real time according to the changes in the patient's body temperature.

[0025] The specific implementation of the present invention includes the following technical modules: central control module, body temperature sensing module, dynamic thermal regulation module, intelligent airflow module, energy management module and data recording and early warning module. Figure 1 As shown, the central control module is electrically connected to each module and is responsible for receiving body temperature data and generating control instructions to ensure that each module works together to accurately control the patient's body temperature.

[0026] 1. Body temperature sensing module

[0027] The body temperature sensing module is one of the core modules of the present invention, which is mainly responsible for real-time monitoring of the patient's body surface temperature. The module includes an infrared sensor array and a skin contact temperature sensor. The infrared sensor array is mounted on the device bracket, has high sensitivity, can non-contactly monitor the patient's body surface temperature, and generate a body surface temperature distribution map. The infrared sensor array can monitor the temperature of multiple parts at the same time to ensure that comprehensive body temperature data is obtained.

[0028] Skin contact temperature sensors are installed on the patient's forehead, neck, armpits and ankles, in close contact with the skin, and can collect temperature data of local areas in real time. These data are transmitted from the body temperature sensing module to the central control module, which dynamically adjusts the temperature control strategy based on these data.

[0029] 2. Dynamic thermal control module

[0030] The dynamic thermal control module consists of a micro-thermopile element and a liquid circulation unit, which is responsible for regulating the local temperature of the patient's body surface. The micro-thermopile element controls heating or cooling through current regulation, and can accurately control the temperature of the target area. The liquid circulation unit transports constant temperature liquid to the target part of the patient's body surface, such as the head, core trunk or limbs, through flexible water pipes, further improving the temperature control effect.

[0031] Micro thermopile elements use the principle of thermoelectric effect to convert electric current into heat energy to achieve heating or cooling functions. The element has a small volume and high heat exchange efficiency, and can effectively adjust the temperature of a local area in a short time.

[0032] The liquid circulation unit contains a micro-circulation pump and a constant temperature liquid storage tank, which can deliver constant temperature liquid to the target part of the patient through a flexible water pipe. The flexible water pipe is made of medical flexible materials to ensure that it can fit the patient's skin, thereby improving temperature control efficiency and comfort. The liquid circulation unit works in conjunction with the micro-thermopile element to ensure accurate body temperature control and provide rapid response. Through this dynamic adjustment, local temperature control can be accurately adjusted for different body positions and surgical areas.

[0033] like Figure 2 As shown, the working schematic diagram of the liquid circulation unit shows the structure of the micro-circulation pump and the constant temperature liquid storage tank, which can intuitively reflect the circulation flow of the constant temperature liquid and its contact with the patient's skin.

[0034] 3. Intelligent airflow control module

[0035] The intelligent airflow control module delivers constant temperature airflow through micro fans and flexible pipes to help regulate the patient's body surface temperature. The fan design allows the airflow to be evenly distributed and effectively transfers heat, thereby coordinating with the dynamic thermal control module to regulate body temperature. The flexible pipe design can flexibly adjust the airflow delivery path according to the patient's body position changes, ensuring that the airflow can cover the patient's key areas, such as the head and torso.

[0036] The temperature of the constant temperature airflow matches the body temperature data in real time. When the central control module detects changes in body temperature, the airflow module automatically adjusts the airflow temperature or flow rate to help the patient maintain a constant body temperature. This intelligent airflow control method can be coordinated with the liquid circulation system to flexibly respond to the body temperature requirements at different stages during surgery.

[0037] 4. Data recording and early warning system

[0038] The data recording and warning module is responsible for storing the patient's body temperature data and issuing an alarm signal when the body temperature exceeds the set range. The data storage unit can record the historical data of each temperature measurement and transmit it to the central control module for postoperative review or analysis. When the body temperature changes beyond the safe range, the warning unit will promptly remind medical staff to take corresponding measures through sound and light signals. The design of the alarm signal ensures that it can quickly attract the attention of medical staff during the operation to prevent the patient's abnormal body temperature from affecting the operation.

[0039] The early warning system has high accuracy and can identify potential abnormal temperature trends in advance, and notify medical staff through a variety of alarm methods (such as sound and light signals, touch screen prompts, etc.), greatly improving the safety of patient temperature management.

[0040] 5. Energy management module

[0041] The energy management module is responsible for managing the power supply of the device, supporting both mains and battery power supply modes. When the external power supply is interrupted, the energy management module will automatically switch to the backup battery mode to ensure that the device can continue to operate stably under any circumstances. This module not only ensures the long-term stable operation of the device, but also improves the safety during surgery.

[0042] 6. Modular and integrated design

[0043] The device of the present invention adopts a modular design, and each functional module is connected through a standard interface, so that the device can be quickly assembled and disassembled. In addition, the device can also be integrated with the operating table to facilitate the stable fixation of the temperature control device during the operation. The flexible pipes and water pipes can fit the patient's skin tightly to ensure the stability and durability of the temperature control effect.

[0044] The integrated design enhances the overall stability and convenience of the device, especially during long surgeries, as medical staff can continuously monitor and regulate the patient's body temperature without having to frequently adjust the equipment.

[0045] Application Examples

[0046] In a neurosurgery operation, a patient needs to undergo a complex operation due to craniocerebral injury. In order to ensure the stability of the patient's body temperature during the operation and avoid postoperative complications caused by excessively high or low body temperature, the neurosurgery patient body temperature precision control device of the present invention is used.

[0047] Before the operation begins, medical staff set the target body temperature range (36.5℃-37.5℃) through the touch screen interface of the central control module. The body temperature sensing module monitors the temperature of the patient's body surface in real time through the infrared sensor array and skin contact temperature sensor, and feeds back to the central control module. At this time, the dynamic thermal control module is activated, and the micro-thermopile element heats or cools the core area of ​​the patient (such as the head and torso), and delivers constant temperature liquid to the patient's skin surface through the liquid circulation unit to keep the body temperature within the set range.

[0048] The intelligent airflow module provides constant temperature airflow for patients to further stabilize the body surface temperature, especially when the patient's limbs are exposed, to avoid local temperature fluctuations through airflow regulation. The data recording and early warning module continuously monitors the patient's body temperature changes, and when the body temperature is abnormal, the alarm unit sends out sound and light warnings to remind medical staff to deal with it in time.

[0049] During the entire operation, the precise temperature control device effectively ensured the patient's body temperature was stable. The operation went smoothly and the patient's postoperative recovery was good. No complications caused by temperature fluctuations occurred.

[0050] In summary, the device for precise temperature control of patients undergoing neurosurgery of the present invention realizes real-time monitoring and precise control of the patient's body temperature by integrating multiple functional modules such as infrared sensor array, skin contact temperature sensor, dynamic thermal control module, intelligent airflow module, data recording and early warning module, etc. The various modules work together to ensure that the patient's body temperature is always within a safe range, providing more precise and efficient temperature management for patients undergoing neurosurgery.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
