[0097] A cylindrical member 20;

[0098] An annular pressure sensor 21 disposed on the bottom surface of the cylindrical member 20;

[0099] A cylindrical heat insulating member 22 disposed on the inner wall of the through hole of the cylindrical member 20;

[0102] The centers of the cylindrical component 20, the annular pressure sensor 21, the cylindrical heat insulating component 22 and the annular mounting hole top plate component 23 coincide with each other;

[0103] Each of the annular pressure sensors 21 is connected to the temperature reduction control device 5 by signal;

[0104] The cooling component 4 is a cylindrical structure, and the cooling component 4 is detachably arranged on the inner wall of the cylindrical heat insulating component 22;

[0105] When the cooling component 4 is disposed on the inner wall of the cylindrical heat insulating component 22, the cooling component 4 and the bottom surface of the annular pressure sensor 21 are in the same plane;

[0106] The hood 1 is made of elastic fabric, the fixing belt 3 is an elastic stretch belt, and the cooling working surface of the cooling component 4 is provided with a cooling protective layer.

[0107] Specifically, the cooling working surface of the cooling component 4 is provided with a cooling protection layer, which is intended to avoid frostbite when placed against the scalp. The cooling protection layer may be a leather gasket or a gasket made of other materials, which can conduct temperature while effectively protecting the scalp.

[0108] As shown in the attached figure of the specification Figure 2 As shown, the cooling component 4 is a cylindrical structure, and the area where its bottom end contacts the scalp, i.e., the cooling working surface, can be set to a flat plane or a curved surface, and is designed according to actual needs.

[0109] It should be noted that in the technical solution of the embodiment of the present application, there are requirements for the layout density of the mounting hole component 2, which needs to meet the layout density requirements of the cooling functional parts required for brain cooling, that is, the cooling component 4 needs to have sufficient density so as to be able to perform synchronous, uniform and effective brain cooling.

[0110] In the embodiment of the present application, the brain cooling device is fixed to the user's head using a hood 1 and a fixing strap 3, and the user's head is cooled based on a cooling component 4. The ear temperature sensor is used to monitor the cooling work status, and the brain cooling work is monitored in real time and adjusted in time to meet the actual needs of the brain cooling work.

[0111] Furthermore, a mounting hole component arrangement area is provided on the head cover 1, and a plurality of the mounting hole components 2 are arranged at intervals in the hole component arrangement area.

[0112] It should be noted that the arrangement area of ​​the mounting hole component 2 includes two situations, which are as follows:

[0113] In the first case, the arrangement area of ​​the mounting hole components 2 covers the entire area of ​​the head cover 1 as much as possible, and at least the coverage area accounts for a proportion of the area of ​​the head cover 1 that is greater than a first area ratio threshold, such as 90%, that is, multiple mounting hole components 2 are arranged at intervals in the area, so that the brain cooling work of the whole head can be performed;

[0114] In the second case, the area where the mounting hole component 2 is arranged only needs to be located in a partial area of ​​the head cover 1. This situation is for patients who undergo brain surgery, remove part of the tissue, or do not need to cool down due to partial tissue injury or other factors. That is, there is no need to subsequently arrange the cooling component 4 in this area, or there is only local brain lesions, and only the brain cooling work in the local area of ​​the lesion needs to be performed.

[0115] Further, the annular mounting hole top plate component 23 includes:

[0116] A first annular top plate 230;

[0117] An annular telescopic member 231 disposed on the bottom surface of the first annular top plate 230;

[0118] A first annular bottom plate 232 is provided on the bottom surface of the annular telescopic member 231; wherein

[0119] The annular telescopic member 231 is connected to the temperature reduction control device 5 by signal;

[0120] The centers of the first annular top plate 230, the annular telescopic member 231 and the first annular bottom plate 232 coincide with each other;

[0121] The first annular bottom plate 232 is disposed on the top of the cylindrical component 20;

[0122] The upper surface of the first annular top plate 230 is provided with an annular light plate 233;

[0123] The annular light panel 233 is connected to the temperature reduction control device 5 by signal.

[0124] Furthermore, the cooling component 4 is detachably arranged on the inner wall of the cylindrical heat insulating component 22 through a threaded structure;

[0125] The size of the cooling component 4 matches the inner diameters of the first annular top plate 230, the annular telescopic member 231, the first annular bottom plate 232 and the through hole of the cylindrical heat insulating component 22;

[0126] The inner diameters of the through holes of the first annular top plate 230 , the annular telescopic member 231 , the first annular bottom plate 232 , and the cylindrical heat insulating component 22 are the same.

[0127] Furthermore, the temperature reduction control device 5 is used to receive the monitoring pressure value of the annular pressure sensor 21, and is also used to receive the monitoring temperature value of the ear temperature sensor 6;

[0128] The temperature reduction control device 5 is also used to control the temperature reduction component 4 to perform temperature reduction work;

[0129] When the monitoring pressure value of the annular pressure sensor 21 is less than the preset minimum monitoring pressure value, the temperature reduction control device 5 is further used to control the annular telescopic member 231 to extend, thereby driving the annular pressure sensor 21 and the cooling component 4 to descend synchronously; when the monitoring pressure value of the annular pressure sensor 21 is not less than the minimum monitoring pressure value, the temperature reduction control device 5 is further used to control the annular telescopic member 231 to stop extending and maintain;

[0130] When the monitoring pressure value of the annular pressure sensor 21 is greater than the preset maximum monitoring pressure value, the temperature cooling control device 5 is also used to control the annular telescopic member 231 to contract, thereby driving the annular pressure sensor 21 and the cooling component 4 to rise synchronously; when the monitoring pressure value of the annular pressure sensor 21 is not greater than the minimum monitoring pressure value, the temperature cooling control device 5 is also used to control the annular telescopic member 231 to stop contracting and maintain.

[0131] Further, when the annular telescopic member 231 is extended to the limit state, and the monitoring pressure value of the annular pressure sensor 21 is still less than the preset minimum monitoring pressure value, the temperature reduction control device 5 is also used to control the annular light panel 233 to flash according to the preset pressure abnormality reminder frequency and the preset pressure abnormality reminder color;

[0132] When the annular telescopic member 231 contracts to the limit state, and the monitoring pressure value of the annular pressure sensor 21 is still greater than the preset maximum monitoring pressure value, the temperature reduction control device 5 is also used to control the annular light panel 233 to flash at a preset pressure abnormality reminder frequency and in a preset pressure abnormality reminder color.

[0133] Furthermore, the brain cooling device also includes:

[0134] An installation area database module 7, which is used to store brain areas corresponding to different installation hole component 2 positions, so as to be applied to individualized application scenarios where partial cooling components are required to be used for cooling treatment of local brain areas;

[0135] The cooling control device 5 is also used to receive the brain injury type and location corresponding to the patient, compare with each of the preset brain injury types and locations stored in the installation area database module 7, and obtain the cooling area and temperature recommendation information of the matching preset brain injury type;

[0136] The temperature reduction control device 5 is also used to control the annular light panel 233 of the mounting hole component 2 corresponding to the temperature reduction area and the temperature recommendation information to flash according to a preset installation reminder frequency and a preset installation reminder color.

[0137] It should be noted that the annular light panel 233 flashes in a preset installation reminder color at a preset installation reminder frequency, aiming to remind the user that the cooling component 4 needs to be installed on the corresponding installation hole component 2.

[0138] Furthermore, the temperature reduction control device 5 is also used to control the annular light panel 233 of the mounting hole component 2 that is not included in the temperature reduction area recommendation information to flash according to a preset no-installation reminder frequency and a preset no-installation reminder color.

[0139] Furthermore, the cooling control device 5 is also used to control the annular light panel 233 of the mounting hole component 2 which is included in the cooling area recommendation information and on which the cooling control device 5 is installed to flash according to a preset installed reminder frequency and a preset installed reminder color.

[0140] Furthermore, the cooling control device 5 is also used to control the annular light panel 233 of the corresponding mounting hole component 2 to flash at a preset high temperature reminder frequency and in a preset high temperature reminder color when the monitoring temperature value of the ear temperature sensor 6 is greater than a preset monitoring temperature maximum threshold.

[0141] Furthermore, the cooling control device 5 is also used to control the corresponding cooling component 4 to increase the cooling power when the monitored temperature value of the ear temperature sensor 6 gradually increases and the temperature increase acceleration gradually increases, and the power increase acceleration increases accordingly based on the value of the temperature increase acceleration.

[0142] At present, the commonly used head cooling methods in clinical practice are mainly rubber water-filled ice caps and electronic ice caps. The rubber water-filled ice cap is made of rubber, which becomes hard after freezing, has poor comfort, cannot fit tightly against the patient's head, and has a poor cooling effect. Moreover, when the ice in the ice cap melts, it flows to both sides, resulting in no ice water on the top, and the local cooling effect is not ideal. The electronic ice cap is made of hard cloth and has a foldable and modular structure. It uses an external cooling device to dissipate the heat from the patient's head using circulating ice water. Traditional electronic ice caps are inconvenient to wear and have poor controllability.

[0143] The cooling component 4 of the embodiment of the present application can adopt a thermocouple type cooling and heating device to better adapt to the use environment of the present application, and the cooling power of the cooling component 4 can specifically be the output power of the selected cooling and heating device, that is, the degree of influence of the cooling work on the temperature per unit time.

[0144] Furthermore, the cooling control device 5 is also used to control the corresponding cooling component 4 to reduce the cooling power when the monitored temperature value of the ear temperature sensor 6 gradually increases and the temperature increase acceleration gradually decreases, and the power reduction acceleration is correspondingly reduced based on the value of the temperature increase acceleration.

[0145] Furthermore, the temperature reduction control device 5 is also used to set the first interval replacement time based on the value of the temperature increase acceleration when the monitored temperature value of the ear temperature sensor 6 gradually increases and the temperature increase acceleration gradually decreases;

[0146] The corresponding cooling component 4 is controlled to reduce the cooling power, and the corresponding power increase acceleration is controlled to alternately operate between maintaining the value unchanged and correspondingly reducing the value based on the temperature increase acceleration, and the interval time of the alternating operation is the first interval replacement time.

[0147] Among them, when the monitored temperature value of the ear temperature sensor 6 gradually increases, and the temperature increase acceleration gradually decreases, it indicates that the brain temperature is decreasing, and the temperature increase is suppressed. At this time, the intensity of temperature reduction can be slowed down to a certain extent, that is, the corresponding cooling component 4 is controlled to reduce the cooling power, and how to regulate the intensity of slowing down the temperature reduction is to reduce the power reduction acceleration based on the value of the temperature increase acceleration;

[0148] The following example illustrates this:

[0149] Assuming that the value of the temperature increase acceleration is a, combined with the preset standard temperature increase acceleration A and the standard interval replacement time T, the first interval replacement time t1 is set;

[0150] t1=(a / A)*T.

[0151] After the first interval replacement time is set, the corresponding power boost acceleration is controlled to alternate between maintaining the value unchanged and decreasing the value of the temperature boost acceleration accordingly, as follows:

[0152] The above operation includes the first operation, that is, the position of the value remains unchanged,

[0153] The second operation is to reduce the power increase acceleration based on the value of the temperature increase acceleration, so that the temperature is adjusted slowly;

[0154] At this time, based on the first operation and the second operation, that is, after the first operation is executed for the first interval replacement time t1, the second operation is executed again for the first interval replacement time t1, and so on alternately;

[0155] The first operation and the second operation are intended to make the temperature adjustment more gradual.

[0156] Furthermore, the cooling control device 5 is also used to control the corresponding cooling component 4 to reduce the cooling power when the monitored temperature value of the ear temperature sensor 6 gradually decreases and the temperature reduction acceleration gradually increases, and the power reduction acceleration is correspondingly reduced based on the value of the temperature reduction acceleration.

[0157] Furthermore, the cooling control device 5 is also used to control the corresponding cooling component 4 to increase the cooling power when the monitored temperature value of the ear temperature sensor 6 gradually decreases and the temperature reduction acceleration gradually decreases, and the power increase acceleration is correspondingly increased based on the value of the temperature reduction acceleration.

[0158] Furthermore, the temperature reduction control device 5 is also used to set the second interval replacement time based on the value of the temperature reduction acceleration when the monitored temperature value of the ear temperature sensor 6 gradually decreases and the temperature reduction acceleration gradually increases;

[0159] The corresponding cooling component 4 is controlled to reduce the cooling power, and the corresponding power reduction acceleration is controlled to alternate between maintaining the value unchanged and reducing the power reduction acceleration based on the value of the temperature reduction acceleration, and the interval time of the alternating operation is the second interval replacement time.

[0160] Among them, when the monitored temperature value of the ear temperature sensor 6 gradually decreases, and the temperature reduction acceleration gradually increases, it indicates that the brain temperature is decreasing, and the temperature reduction is gradually accelerating. At this time, the brain temperature is improving, and the driving force for improvement is gradually increasing. At this time, the intensity of temperature reduction can be slowed down to a certain extent, that is, the corresponding cooling component 4 is controlled to reduce the cooling power, and how to regulate the intensity of slowing down the temperature reduction is to reduce the power reduction acceleration based on the value of the temperature reduction acceleration;

[0161] The following example illustrates this:

[0162] Assuming that the value of the temperature reduction acceleration is b, combined with the preset standard temperature increase acceleration B and the standard interval replacement time T, the first interval replacement time t2 is set;

[0163] T2 = (b / B)*T.

[0164] After the second interval replacement time is set, the corresponding power increase acceleration is controlled to alternate between maintaining the value unchanged and decreasing the value of the temperature decrease acceleration accordingly, as follows:

[0165] The above operation includes the first operation, that is, the position of the value remains unchanged,

[0166] The second operation is to perform a power reduction acceleration reduction operation based on the value of the temperature reduction acceleration, so that the temperature is adjusted slowly;

[0167] At this time, based on the first operation and the second operation, that is, after the first operation is executed for the second interval replacement time t2, the second operation is executed again for the second interval replacement time t2, and so on alternately;

[0168] The first operation and the second operation are intended to make the temperature adjustment more gradual.

[0169] Similarly, when the monitored temperature value of the ear temperature sensor 6 gradually decreases and the temperature reduction acceleration gradually decreases, the cooling control device 5 controls the corresponding cooling component 4 to increase the cooling power, and the power increase acceleration is correspondingly increased based on the value of the temperature reduction acceleration.

[0170] The above operation process is similar to the process described above, and is also for making the temperature adjustment smoother.

[0171] Furthermore, the temperature reduction control device 5 is used to control the corresponding annular light panel 233 to flash with a temperature change abnormality reminder color at a preset temperature change abnormality reminder frequency when the temperature increase acceleration of the temperature value monitored by the ear temperature sensor 6 exceeds a preset temperature increase acceleration threshold or the temperature decrease acceleration exceeds a preset temperature decrease acceleration threshold.

[0172] Furthermore, the temperature reduction control device 5 is used to control the corresponding temperature reduction component 4 to stop cooling when the monitoring temperature value of the ear temperature sensor 6 is lower than a set safety temperature threshold.
