Description of the Invention: [Technical Field of the Invention] The present invention relates to object monitoring, and more particularly to a device for monitoring an object, and a method and system for monitoring and cooling an object. [Prior Art] MIT (Magnetic Inductive Tomography) is a non-invasive and non-contact approach suitable for biomedical applications. For example, a Μίτ device can be used to monitor a patient's brain by measuring the conductivity distribution of a patient's brain. If the change in the PCT measurement is large enough, this can indicate the occurrence of a brain injury. One of the applications of MIT is to monitor bleeding in the brain after neurosurgery, and another potential application is to monitor the presence of secondary stroke events when the patient is asleep at night. The American Heart Association reports that in the United States, about 7 years a year, deaf people suffer a stroke, and 33% of them are recurrent. Furthermore, in a study, 25% of stroke events occurred during a person's sleep. Another study revealed that in 54 〇/〇 stroke patients, stroke occurred during sleep. This information shows that strokes usually occur when people are asleep and are not aware of it. In addition, cryotherapy after brain injury has been found to be a method for saving nerve cells and other brain cells. Studies have shown that cooling the brain tissue to a temperature of 30 ° C to 34 ° C can delay the death of nerve cells and other cells. Therefore, when an MIT device is used to monitor such patients and a brain injury is detected, 'subsequent actions must be taken as soon as possible to protect the brain after a stroke or bleeding event because the damage to the brain cells is irreversible. . For stroke patients or patients with bleeding, time is very valuable, because only 156250.doc 201208553 can give the most effective treatment within 3 to 6 hours after the onset of symptoms - H # so far, - MIT device only on the screen The results of the measurements are output and waiting for the doctor or medical staff to follow up (10), so the patient may not be processed in time. SUMMARY OF THE INVENTION The present invention is based on the insight that a cooling system should be automatically controlled by the measurement results of an object monitoring device such that it can be beneficial to t-wind patients by delaying the death of brain cells and extending valuable time windows, especially For patients who suffer from - stroke or bleeding during their sleep. Furthermore, if the measurement indicates brain damage, an _alarm can be sent so that the medical staff can immediately process the patient. The present invention provides methods, apparatus, and systems that implement the above concepts. According to an aspect of the invention, there is provided a device for monitoring an object, the device:: but a cooling system of the object is connected, the device comprising: a test meter 7G for measuring a conductance of the object Rate distribution; judgement 7L 'is used to determine whether the conductivity distribution of the object or the parameter derived from the conductivity distribution is within a predefined range; - a generating unit for determining the conductivity if the determining unit determines The distribution or the parameter derived from the conductivity distribution is not in the predefined (four), a control signal is generated; and the control unit 7 is used to control the cooling system according to the control signal to cool the object to a constant temperature value. π = in the middle. The quenching system is automatically activated by the measurement result of the device, so that the 1st measurement of the device indicates that the object is damaged, and the cooling system 156250.doc 201208553 will lower the temperature of the object as soon as possible. In one embodiment, the apparatus is a magnetic induction tomography apparatus. In another embodiment, the generating unit is further adapted to: if the determining unit determines the conductivity distribution or derives from the conductivity distribution If the parameter is not within a predefined range, an alert is generated and sent. In this case, the object can be processed in time and the most effective treatment can be given within a valuable time window. In a further embodiment, the system is in a human head, and the predefined range and the predetermined temperature value are set according to the type of brain damage of the head and the health of the person. Other objects and results of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings. [Embodiment] The present invention will be described in conjunction with the embodiments and described in more detail below with reference to the drawings. The same reference numbers in the figures indicate similar or corresponding features and/or functions. An embodiment of the invention will be described in more detail below with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a block diagram of an apparatus 10 for monitoring an object in accordance with the present invention. Referring to Figure 1, the apparatus 10 includes a metrology unit 11 for measuring a conductivity distribution of an object after receiving a chirp (measurement command). The cassette can be entered by pressing the button by the user. 156250.doc 201208553 In an embodiment, the device is disposed and the object can be a human head. ’’·, Inductive tomography array) is used to measure the conductivity of the brain. Other parameters can be measured from the measurement. In this case, the measurement unit! Can be clothed. As is well known to those skilled in the art, the conductivity distribution of the element 11 measurement is derived. The determining unit 12 is configured to determine whether the object rate distribution derives a t parameter whether or not the device 10 further includes a conductivity distribution or a range from the electrical conductivity. In other words, if the (four) body's electrical (four) distribution or the parameter derived from the electrical (four) distribution is not in the -predefined range order, then this can be a finger of a brain injury, such as a wind or during a sleep time. A bleeding in the brain after neurosurgery and so on. The apparatus 10 further includes a generating unit 13 for generating a control signal if the determining unit 12 determines that the conductivity distribution or the parameter derived from the conductivity distribution is not within a predefined range. The apparatus 10 further includes a control unit 14 for controlling the cooling system CS based on the control signal to cool the object to a predetermined temperature value. In a consistent embodiment, the predefined range and the predetermined temperature value are set according to the type of brain damage of the head and the health of the person. The study indicated that the brain tissue was cooled to 30. (: to 34. (A temperature of one can delay the death of nerve cells and other cells. Therefore, the predetermined temperature value is based on the type of brain damage (for example, a bleeding after neurosurgery or a stroke during sleep time) In addition, the predetermined temperature value may also be set according to the health condition of the patient, for example, blood pressure, heart rate, heart and brain blood 156250.doc 201208553 disease history of the disease, etc. Similarly, the conductivity distribution of the object Or the predefined range of parameters derived from the conductivity distribution can be set according to the type of brain damage of the human head and the health of the person. As discussed above, because the cooling system can be accessed without a doctor or medical staff Automatically controlled and activated by the measurement of the -MIT device, (4) The temperature therapy can be started as soon as possible to protect the brain. In another implementation, the generating unit 13 is adapted to: if the determining unit determines the conductivity distribution Or the parameter derived from the conductivity distribution is not in the predefined range, then an alarm is generated and sent out. In this case, once detected by the device To a brain injury, by generating and sending out-alarms to medical staff, or to relatives directly in the vicinity of the patient, the patient can be treated in time and the most effective treatment can be given within a valuable time window. In one embodiment 'The control unit 14 is further configured to: if the decision unit 12 determines; t the conductivity distribution or the parameter derived from the conductivity distribution is within a predefined range, the temperature value of the brain surface is maintained at ambient The temperature is uniform. Therefore, in the case of a slight brain injury that is self-healing, for example, a slight bleeding, the measurement of the measuring unit ij can be returned to the predefined range, and then the control unit 14 can control the cooling system, Increasing the temperature of the object to room temperature may reduce any side effects or severe hypothermia complications to the patient. It may also occur if the measurement of the measurement unit is not sufficient for a certain period of time 156250.doc 201208553 Accurate and the cooling system is improperly activated, the measurement of the measuring unit 亦可 can also be returned to the predefined range. In this case, if the measurement If the measurement of element 11 returns to a normal value, the cooling system can raise the temperature of the object to room temperature to protect the object from improper handling. Please note that although the present invention uses only one device, the device is used as a device. One example of 10, for those skilled in the art, will readily contemplate the use of any device that can monitor the object and measure the conductivity distribution of a human head and then determine if there is a brain damage, such as electrical impedance tomography (EIT). Electrical impedance tomography (ERT), capacitive tomography (ECT), t-magnetic tomography (EMT), and magnetic resonance electrical impedance tomography (MREIT) devices.

Figure 3 shows a system for monitoring and cooling an object in accordance with the present invention. The system of the invention comprises the MIT device as mentioned above and a cooling system connected to the MIT device. In detail, the MIT device comprises a basic MIT hardware 301 comprising a magnetic transmitting/receiving coil, a protective cover and others An essential component to monitor the object 302 ° In addition, the MIT device includes a control unit 312 for controlling the cooling system to cool the object to a predetermined temperature value based on a control signal generated by the MIT hardware 301 Since the MIT device has been described in detail above, further description thereof is omitted herein. 156250.doc • 10·201208553 The present invention describes a cooling system employed in the system, according to an embodiment of the present invention. For monitoring and cooling an object. As shown in FIG. 3, the cooling system includes: a pillow having a heat transfer fluid 3G3 in the body 314 of the pillow; and a tube system 316 It has a cooling fluid 3G8 circulating therein and exchanges heat with the pillow 313 to cool the object 302, which in this example is a human head. The cooling system can be configured to comfort the patient during sleep. The time is a comfortable normal pillow, and the brain of the patient is protected as soon as possible when the brain is damaged. As shown, the body 314 of the pillow 313 further includes an upper layer 3〇4, which is adapted to Supporting the object 3〇2 and directly contacting the object 302. The upper layer 3〇4 is thermally conductive and relatively soft. In the pillow 313, there is a through hole adapted to contain the tube of the tube system 3 16 3〇 7. The tube system 316 includes two different tubes. One of the 307s in the through hole of the pillow 313 is made of a thermally conductive material, and the other 306 outside the pillow 313 is made of a thermally insulating, non-conductive, and rigid material. As a result, the coolant 308 in the tube 307 can exchange heat with the heat transfer fluid 3〇3 in the pillow, and the coolant 308 will not heat as it passes through the tube 306 because it is thermally insulated, non-conductive. And the hard material is made, and thus the thermal efficiency can be improved. In an embodiment, the tube system 316 further includes: a cooling pump 310' for driving the coolant 308 circulating in the tube system 316; and a control unit 309' for the The cooling pump 310 is controlled by a control signal of the control unit 3 12 . 156250.doc -11 - 201208553 In an embodiment the pillow 313 further comprises at least one branch 315 made of a thermally insulating, non-conductive and rigid material 3〇5. Although two branch pipes 3 are shown on both sides of the object 302, it will be readily understood by those skilled in the art that there may be only one branch pipe or more than two branch pipes 315 ° as needed. The branch pipe 315 may be associated with the pillow 313 The body 314 is in communication such that when the object 302 lies in the pillow 313, the upper layer 304 is curved to form a recess, causing the heat transfer fluid 303 to rise in the branch 315, thereby controlling the object 302 to be fixed. Position, and due to the force induced by the difference in height of the heat transfer fluid 3〇3, the upper layer 304 of the pillow 313 remains in intimate contact with the object 302. Since the object 302 can be controlled to be in a fixed position and it will not move relative to the MIT device, the measurement accuracy of the MIT device can be improved. Further, because the upper layer 304 of the pillow 313 remains in close contact with the object 302, the object 302 can be effectively cooled, and thus the effect of delaying nerve cells and other cell death can be enhanced. In another embodiment, the system can further include a temperature sensor 3 11 for sensing the temperature value of the object 302. As shown in Fig. 3, the temperature sensor 311 can be placed at the upper layer 3〇4 or the surface of the brain as long as it can sense the temperature value at the surface of the brain. It is to be noted that the above-mentioned embodiments are illustrative and not limiting, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims.
