Description

Technical Field

[0001] The invention relates to the technical field of medical thermal insulation blanket heating, and in particular to a medical temperature increasing instrument and a temperature monitoring method thereof. Background Art

[0002] Hypothermia during surgery is a problem that cannot be ignored. According to clinical data, the incidence of hypothermia in patients during surgery can be as high as 50% to 70%, which means that about half of the patients will have a body temperature below 36°C during surgery. What's more serious is that about one-third of the patients will even have a body temperature below 35°C during surgery. This phenomenon may have adverse effects on the patient's physiological functions and surgical results. Therefore, for patients whose surgery time exceeds expectations, it is particularly important to keep the body temperature stable. In the medical field, a medical thermal blanket is a thermal insulation device designed specifically for medical environments. It can control the temperature through a built-in temperature control system and sensor, thereby achieving stable maintenance of the patient's body temperature.

[0003] In the prior art, the set temperature of a medical thermal blanket is usually set manually, and the patient's body temperature is improved and maintained by using a medical thermal blanket with a set temperature. However, in actual situations, the set temperature of the medical thermal blanket set manually is inaccurate, and the patient's body temperature changes under the influence of other factors such as the medical thermal blanket. If the fixed set temperature of the medical thermal blanket cannot respond to changes in the patient's body temperature in time, and the temperature of the medical thermal blanket cannot be adaptively adjusted according to changes in the patient's body temperature, it is impossible to avoid abnormal low body temperature of the patient during surgery or treatment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a medical temperature raising instrument and a temperature monitoring method thereof which can accurately set the temperature and timely and effectively improve the abnormal low temperature of the patient's body temperature.

[0062] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of a medical temperature increasing device and a temperature monitoring method thereof proposed according to the present invention, its specific implementation, structure, features and effects, in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0063] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0064] The specific scheme of a medical temperature increasing device and a temperature monitoring method thereof provided by the present invention is described in detail below with reference to the accompanying drawings.

[0065] Embodiment 1: A method for monitoring the temperature of a medical temperature increasing device, such as Figure 1 As shown, the method comprises the following steps:

[0066] Step 1: Obtain the patient's body temperature and the temperature of the medical warming blanket at each moment.

[0067] Specifically, in order to effectively solve the low temperature situation of patients during surgery, this embodiment takes a graphene medical thermal blanket as an example for analysis, and all subsequent medical thermal blankets are graphene medical thermal blankets. Medical thermal blanket is a medical auxiliary equipment, and its structural design takes into account the insulation needs during surgery. The medical thermal blanket uses graphene as the main heating material, has conductive and thermal conductivity, and can convert electrical energy into thermal energy. At the same time, in order to enhance the durability and cleanability of the medical thermal blanket, the medical thermal blanket uses a wipeable and machine-washable carbon fiber material to prevent cross infection. In addition, the design of the medical thermal blanket can be cut according to the human body shape and the size of the operating bed to ensure fit. Among them, the heating elements of the medical thermal blanket are arranged in the best insulation area of ​​the human body surface, such as shoulders, arms, lower limbs, etc., to achieve efficient insulation effect.

[0068] Before surgery, lay the medical insulation blanket flat on the operating table to ensure that the parts of the patient that need to be kept warm are covered. Use elastic buckles to firmly fix the medical insulation blanket to the operating table or the body position frame to prevent sliding. The medical insulation blanket can be equipped with a temperature control function, and the head end is connected to the power supply for easy operation. Its head end is specially designed for warming the shoulder and neck during surgery. At the same time, for the abducted upper limbs, the medical insulation blanket can be unfolded and fixed on the armrest, and when not in use, it is fixed to the bottom of the operating table by adhesive to ensure comprehensive warmth. The edge of the medical insulation blanket for the trunk area adopts an elastic buckle design, which can be firmly fixed to the operating table and effectively prevent sliding. For double lower limb separation surgery or lithotomy surgery, the medical insulation blanket adopts a T-shaped split separation design to provide sufficient warmth for the lower limbs. The lower limb part of the medical insulation blanket is also equipped with elastic buckles, which is convenient for fixing on the body position frame to ensure stability. In routine supine surgery, the medical thermal blanket only needs to be laid flat on the operating table and fixed to the bedside railings with elastic buckles to achieve efficient and comfortable thermal insulation effects.

[0069] The working principle of the medical thermal blanket is based on the excellent electrical and thermal conductivity of graphene materials. When current passes through the graphene heating element, the Joule heating effect is used to efficiently convert electrical energy into thermal energy, and the high thermal conductivity of graphene is used to quickly and evenly conduct heat to the entire blanket surface. At the same time, far-infrared radiation is released to gently raise and maintain the temperature around the human body, achieving a fast, uniform and comfortable thermal insulation effect.

[0070] In terms of temperature monitoring, the medical thermal blanket uses a high-precision temperature sensor that can monitor the temperature of the medical thermal blanket and the patient's body temperature at every moment in real time. The temperature sensor transmits the collected data to the control system, which can quickly respond to the patient's body temperature changes according to the patient's body temperature and automatically adjust the power of the heating element of the medical thermal blanket to achieve stable maintenance of the patient's body temperature during surgery or treatment.

[0071] During surgery or treatment, this embodiment is set to synchronously collect the patient's body temperature and the medical warming blanket temperature once every 1 second, that is, the patient's body temperature and the medical warming blanket temperature at each moment are obtained in real time. The implementer can set the time interval between two adjacent moments of data collection according to actual conditions, which is not limited here.

[0072] Step 2: Determine the abnormal low temperature stage in real time based on the patient's body temperature, and obtain the initial set temperature of the medical thermal blanket according to the degree of change in the patient's body temperature that continues to drop before the abnormal low temperature stage and the temperature of the medical thermal blanket at the beginning of the abnormal low temperature stage.

[0073] During the patient's surgery or treatment, the patient's body cavity is exposed to the outside for a long time, and the water in the body will evaporate a lot, which will also take away heat, causing the patient's body temperature to drop. In order to ensure that the patient's body temperature during the surgery or treatment is maintained in a safe and appropriate range, and to promptly detect abnormal low temperature of the patient's body temperature, the medical staff sets a preset standard patient temperature. When the patient's body temperature is less than or equal to the preset standard patient temperature, the patient's body temperature begins to enter the abnormal low temperature stage, and the abnormal low temperature stage is determined in time. In this embodiment, the preset standard patient temperature is set to 36.3°. The implementer can set the preset standard patient temperature according to the actual situation, which is not limited here.

[0074] Under normal circumstances, the human body temperature is stable. Therefore, if the patient's body temperature drops more obviously before the abnormal low temperature stage, the greater the degree of abnormal temperature. In order to respond to the abnormal temperature of the patient in a timely and effective manner, the initial set temperature of the medical thermal blanket should be higher. In order to accurately obtain the initial set temperature of the medical thermal blanket, this embodiment obtains the initial set temperature of the medical thermal blanket based on the degree of change in the continuous drop in the patient's body temperature before the abnormal low temperature stage and the temperature of the medical thermal blanket at the beginning of the abnormal low temperature stage, so that the abnormal low temperature condition of the patient can be effectively improved later.

[0075] Preferably, in one possible implementation of this embodiment, the method for obtaining the initial set temperature is as follows: Figure 2 , which shows a flow chart of a method for obtaining an initial set temperature provided in this embodiment, the method comprising the following steps:

[0076] Step 201: The time period in which the patient's body temperature continues to drop before the abnormal low temperature stage begins is taken as the target time period, and the abnormal degree of the patient's body temperature is obtained according to the drop in the patient's body temperature during the target time period; wherein the end time of the target time period is the start time of the abnormal low temperature stage.

[0077] In order to analyze the abnormal degree of the patient's body temperature, this embodiment first takes the time period in which the patient's body temperature continues to drop before the low temperature abnormal stage begins as the target time period, wherein the end time of the target time period is the start time of the low temperature abnormal stage. The greater the degree of the patient's body temperature drop within the target time period, the greater the degree of low temperature abnormality of the patient's body temperature. This embodiment obtains the abnormal degree of the patient's body temperature according to the change in the patient's body temperature drop within the target time period. The greater the abnormal degree, the more serious the low temperature of the patient's body temperature.

[0078] In one possible implementation of this embodiment, the method for obtaining the target time period is as follows: the patient's body temperature before the start of the current abnormal low temperature stage is fitted into a curve according to the time sequence from the front to the back, and the tangent slope of each patient's body temperature on the curve is obtained, and the curve segment corresponding to the patient's body temperature that is continuous and uninterrupted and whose tangent slope is less than 0 is used as the reference curve segment, and the time period corresponding to the reference curve segment closest to the current abnormal low temperature stage is used as the target time period. Among them, the curve fitting and the tangent slope acquisition methods are both well-known technologies and will not be described in detail.

[0079] In one possible implementation of the present embodiment, the method for obtaining the degree of abnormality is as follows: fitting the patient's body temperature within the target time period into a curve, obtaining the tangent slope of each patient's body temperature on the curve within the target time period, as the reference change value of the corresponding patient's body temperature; the larger the absolute value of the reference change value, the more obvious the decrease in the corresponding patient's body temperature, which indirectly indicates that the degree of abnormality of the patient's body temperature is greater; in order to more accurately analyze the degree of abnormality of the patient's body temperature, the line segments formed by the patient's body temperature corresponding to the continuous, uninterrupted and equal reference change values ​​are all taken as local line segments, and the duration corresponding to each local line segment is compared with the duration corresponding to the target time period. The ratio of is taken as the participation value of the corresponding local line segment. The larger the participation value, the larger the proportion of the corresponding local line segment in the target time period. Then, the product of the absolute value of the slope of each local line segment and the participation value is obtained as the reference value of the decline of each local line segment. The larger the reference value of the decline, the more obvious the decline trend of the corresponding local line segment. In order to comprehensively analyze the decline of the patient's body temperature in the target time period, the cumulative result of the decline reference value of all local line segments is obtained as the overall decline value of the target time period. The larger the overall decline value, the greater the decline of the patient's body temperature, which indirectly indicates that the abnormality of the patient's body temperature is greater. At the same time, the difference between the maximum patient body temperature and the minimum patient body temperature in the target time period is obtained as the overall change value of the target time period. The larger the overall change value, the greater the decline of the patient's body temperature, which indirectly indicates that the abnormality of the patient's body temperature is greater. Then, this embodiment normalizes the product of the overall change value of the target time period and the overall decline value as the abnormality of the patient's body temperature.

[0080] The calculation formula of abnormality degree is: ; In the formula, Y is the abnormal degree of the patient's body temperature; △S is the overall change value of the target time period; N is the total number of local segments in the target time period; k n is the slope of the nth local line segment in the target time period; II is the absolute value function; t n is the duration corresponding to the nth local segment in the target time period; T is the duration corresponding to the target time period; t n / T is the participation value of the nth local segment in the target time period; is the descending reference value of the nth local line segment within the target time period; is the overall decline value in the target time period; norm is the normalization function.

[0081] Step 202: Obtain the initial set temperature of the medical thermal blanket according to the temperature of the medical thermal blanket at the start of the abnormal low temperature stage, the degree of decrease and abnormality of the patient's body temperature within the target time period, and the initial conversion rate of the medical thermal blanket temperature.

[0082] The original intention of designing a medical thermal blanket is to improve the abnormal low temperature of the patient's body temperature. When the set temperature of the medical thermal blanket increases, the loss of the patient's body temperature can be effectively reduced. Therefore, when the abnormal degree of the patient's body temperature is greater, the set temperature of the medical thermal blanket should be greater; at the same time, when the degree of decrease of the patient's body temperature in the target time period is greater, it also means that the set temperature of the medical thermal blanket should be greater. It is known that a reasonable medical thermal blanket temperature conversion rate is incorporated into the design process of the medical thermal blanket, that is, the amount of increase in the patient's body temperature when the set temperature of the medical thermal blanket increases by one unit temperature. In actual situations, combined with the standard conversion rate of the medical thermal blanket temperature, while considering the individual differences of the patient, age factors, physical conditions and other factors, the medical staff directly gives the initial conversion rate of the medical thermal blanket temperature. In addition, this embodiment obtains the initial set temperature of the medical thermal blanket according to the temperature of the medical thermal blanket at the beginning of the abnormal low temperature stage, the degree of decrease and abnormal degree of the patient's body temperature in the target time period, and the initial conversion rate of the medical thermal blanket temperature.

[0083] In one possible implementation of this embodiment, the method for obtaining the initial set temperature is as follows: considering that the greater the absolute value of the slope of the local line segment, the more significant the trend of the patient's body temperature decreasing, which indirectly indicates that the abnormal degree of the patient's body temperature is greater, therefore, the degree of change in the patient's body temperature within a unit time period should be greater, so as to effectively improve the abnormal low temperature of the patient, and then this embodiment obtains the average of the absolute values ​​of the slopes of all local line segments as the unit patient temperature change value; in order to accurately obtain the initial set temperature of the medical thermal blanket in the abnormal low temperature stage, this embodiment first obtains the unit patient temperature The product of the temperature change value and the degree of abnormality is taken as the patient's body temperature increase value; then the sum of the unit patient temperature change value and the patient temperature increase value is taken as the unit patient temperature requirement value; finally, the ratio of the unit patient temperature requirement value to the initial conversion rate of the medical thermal blanket temperature is taken as the unit medical thermal blanket temperature requirement value, which accurately reflects the required increase in the medical thermal blanket temperature at the beginning of the low temperature abnormality stage, and then the sum of the medical thermal blanket temperature at the beginning of the low temperature abnormality stage and the unit medical thermal blanket temperature requirement value is taken as the initial set temperature of the medical thermal blanket.

[0084] The calculation formula for obtaining the initial set temperature is: Where W 1 ' is the initial setting temperature of the medical thermal blanket; W 1 The temperature of the medical thermal blanket at the beginning of the abnormal low temperature stage; is the change value of the patient's body temperature; Y is the abnormal degree of the patient's body temperature; is the patient's body temperature increase value; is the required value of body temperature of a unit patient; f 1 is the initial conversion rate of the temperature of the medical thermal blanket; is the required temperature of the unit medical thermal blanket; II is the absolute value function.

[0085] Adjust the initial setting temperature of the medical insulation blanket to W 1 ', start warming the patient. It should be noted that if the temperature of the medical thermal blanket is set too high, it may cause heat stroke and other problems in the patient. Therefore, it is necessary to ensure that the set temperature of the medical thermal blanket is less than or equal to the preset medical thermal blanket temperature threshold. If the set temperature of the medical thermal blanket obtained is greater than the preset medical thermal blanket temperature threshold, the preset medical thermal blanket temperature threshold is set as the set temperature of the medical thermal blanket. The implementer can set the preset medical thermal blanket temperature threshold according to the actual situation, which is not limited here.

[0086] Step 3: Divide the preset time period from the beginning of the abnormal low temperature stage, and obtain the patient's warming degree in the initial preset time period based on the patient's body temperature and medical warming blanket temperature at each moment in the initial preset time period, the timely initial set temperature and the initial conversion rate of the medical warming blanket temperature.

[0087] Specifically, after entering the abnormal low temperature stage, the patient's body temperature is first adjusted according to the initial set temperature of the medical thermal blanket. When the patient's body temperature still maintains a downward trend, it means that the patient is still in a state of temperature loss, and the medical thermal blanket needs to be continuously heated or the set temperature of the medical thermal blanket needs to be increased; when the patient's body temperature remains relatively stable or shows signs of recovery, it means that the patient's body temperature has been warmed up in time. In order to avoid excessive heating of the patient, the set temperature of the medical thermal blanket needs to be maintained or reduced. In order to reasonably adjust the set temperature of the medical thermal blanket, the preset time period is divided from the beginning of the abnormal low temperature stage, and the change of the patient's body temperature in each preset time period is analyzed to obtain the set temperature of the medical thermal blanket in the next preset time period in real time. In this embodiment, the preset time period is set to 30 seconds. The implementer can set the size of the preset time period according to the actual situation, which is not limited here. It is known that the set temperature of the medical thermal blanket changes with the change of the patient's body temperature, and essentially changes with the time sequence. Then, this embodiment first analyzes the change of the patient's body temperature in the initial preset time period. It should be noted that the set temperature of the medical thermal blanket within the initial preset time period is the initial set temperature of the medical thermal blanket.

[0088] This embodiment first predicts the patient's predicted temperature at each moment in the initial preset time period based on the difference between the initial set temperature and the temperature of the medical thermal blanket at each moment in the initial preset time period, and the patient's body temperature at each moment in the initial preset time period; if the difference between the patient's predicted temperature at each moment and the patient's body temperature in the initial preset time period is relatively small, it means that the patient's body temperature is better in the initial preset time period. Then, this embodiment obtains the patient's temperature recovery degree in the initial preset time period based on the patient's body temperature and the medical thermal blanket temperature at each moment in the initial preset time period, the initial set temperature, and the initial conversion rate of the medical thermal blanket temperature. The greater the patient's temperature recovery degree, the better the patient's body temperature is in the initial preset time period.

[0089] Preferably, in one possible implementation of the embodiment, the method for obtaining the patient's rewarming degree is as follows: Figure 3 , which shows a flow chart of a method for obtaining the degree of patient rewarming provided by this embodiment, the method comprising the following steps:

[0090] Step 301: Obtain the patient's predicted temperature.

[0091] For any moment within the initial preset time period, first, the difference between the initial set temperature and the temperature of the medical thermal blanket at that moment is taken as the temperature increase value of the medical thermal blanket at that moment; then, the product of the temperature increase value of the medical thermal blanket and the initial conversion rate of the medical thermal blanket temperature is taken as the temperature increase value of the patient at that moment, and the temperature increase value of the patient at that moment is predicted; finally, the sum of the patient's temperature at that moment and the temperature increase value of the patient is taken as the predicted temperature of the patient at that moment. It should be noted that the initial conversion rate of the medical thermal blanket temperature is the conversion rate of the medical thermal blanket temperature within the initial preset time period.

[0092] Among them, the calculation formula for obtaining the patient's predicted temperature is: Where, P 1,i 'Predicted temperature of the patient at the i-th moment within the initial preset time period; P 1,i is the patient's body temperature at the i-th moment in the initial preset time period; W 1 ' is the initial setting temperature of the medical thermal blanket; W 1,i is the temperature of the medical thermal blanket at the i-th moment in the initial preset time period; f 1 is the initial conversion rate of the medical thermal blanket temperature; W 1 '-W 1,i is the temperature rise value of the medical thermal blanket at the i-th moment within the initial preset time period; is the patient's body temperature increase value at the i-th moment within the initial preset time period.

[0093] It should be noted that W 1 '-W 1,i Must be a non-negative number.

[0094] At this point, the predicted temperature of the patient at each moment in the initial preset time period is obtained.

[0095] Step 302: Obtain the patient's rewarming degree.

[0096] The more equal the patient's predicted temperature and the patient's body temperature at each moment in the initial preset time period are, the more obvious the patient's body temperature recovery is in the initial preset time period. Therefore, this embodiment accumulates the difference between the patient's predicted temperature and the patient's body temperature at each moment in the initial preset time period, performs negative correlation and normalization, and uses the result as the patient's temperature recovery degree in the initial preset time period.

[0097] The calculation formula for the patient's rewarming degree is: Where R 1 is the patient's rewarming degree in the initial preset time period; MM is the total number of moments in the initial preset time period; P 1,m 'Predicted temperature of the patient at the mth moment within the initial preset time period; P 1,m is the patient's body temperature at the mth moment in the initial preset time period; exp is an exponential function with a natural constant as the base.

[0098] Step 4: Obtain the set temperature of the medical thermal blanket for the second preset time period based on the initial set temperature, the degree of patient warming in the initial preset time period, and the temperature change of the medical thermal blanket in the initial preset time period.

[0099] When the patient's temperature returns to normal in the initial preset time period, it means that the patient's body temperature is still in a state of hypothermia, that is, the patient's body temperature is on a downward trend. In order to effectively improve the patient's hypothermic state, the set temperature of the medical thermal blanket in the second preset time period should be increased on the basis of the initial set temperature; when the patient's temperature returns to normal in the initial preset time period, it means that the patient's body temperature shows signs of recovery. In order to avoid the medical thermal blanket from overheating the patient, the set temperature of the medical thermal blanket in the second preset time period should be reduced on the basis of the initial set temperature. In order to accurately and quickly obtain the set temperature of the medical thermal blanket in the second preset time period, this embodiment further analyzes the temperature change of the medical thermal blanket in the initial preset time period as a basis for assisting the adjustment of the set temperature of the medical thermal blanket in the second preset time period. Furthermore, this embodiment obtains the set temperature of the medical thermal blanket in the second preset time period based on the initial set temperature, the degree of patient temperature return in the initial preset time period, and the temperature change of the medical thermal blanket in the initial preset time period.

[0100] Preferably, in a method that can be implemented in this embodiment, the method for obtaining the set temperature of the medical thermal blanket for the second preset time period is: obtaining the difference between the maximum temperature and the minimum temperature of the medical thermal blanket in the initial preset time period as the first change value; obtaining the difference between the patient's warming degree in the initial preset time period and the preset patient warming degree threshold as the first characteristic value; when the first characteristic value is a positive number, the better the patient's body temperature is warmed up in the initial preset time period, the smaller the set temperature of the medical thermal blanket for the second preset time period should be in order to avoid excessive heating of the patient by the medical thermal blanket; when the first characteristic value is a negative number, the worse the patient's body temperature is warmed up in the initial preset time period, the larger the set temperature of the medical thermal blanket for the second preset time period should be in order to improve the patient's body temperature in a timely and effective manner; in this embodiment, the preset patient warming degree threshold is set to 0.4, and the implementer can set the size of the preset patient warming degree threshold according to actual conditions, which is not limited here. In order to accurately obtain the set temperature of the medical thermal blanket for the second preset time period based on the initial set temperature, and then obtain the product of the first change value and the first characteristic value as the reference value for adjusting the temperature of the medical thermal blanket for the second preset time period; then use the difference between the initial set temperature and the reference value for adjusting the temperature of the medical thermal blanket as the set temperature of the medical thermal blanket for the second preset time period.

[0101] The calculation formula for obtaining the set temperature of the medical thermal blanket in the second preset time period is:

[0102] Where W 2 'Set the temperature of the medical thermal blanket for the second preset time period; W 1 ' is the initial set temperature of the medical thermal blanket; △W 1 The first change value; R 1 is the patient's rewarming degree during the initial preset time period; r is the preset patient rewarming degree threshold; R 1 -r is the first eigenvalue; A reference value is provided for the temperature adjustment of the medical warming blanket for a second preset time period.

[0103] Step 5: According to the changes in the patient's body temperature and the temperature of the medical thermal blanket within the initial preset time period, and the initial conversion rate of the medical thermal blanket temperature, obtain the conversion rate of the medical thermal blanket temperature for the second preset time period.

[0104] As the patient's body temperature rises, the gap between the patient's body temperature and the set temperature of the medical thermal blanket gradually narrows, so the effect of the medical thermal blanket on raising the patient's body temperature will also be weakened accordingly. It is known that the function of a medical thermal blanket is to maintain or raise the patient's body temperature, not to heat the patient indefinitely. Therefore, the temperature conversion rate of the medical thermal blanket in each preset time period needs to be adaptively adjusted based on the changes in the patient's body temperature and the temperature of the medical thermal blanket in the previous adjacent preset time period, as well as the temperature conversion rate of the medical thermal blanket; further, this embodiment obtains the temperature conversion rate of the medical thermal blanket in the second preset time period based on the changes in the patient's body temperature and the temperature of the medical thermal blanket in the initial preset time period, as well as the initial conversion rate of the medical thermal blanket temperature.

[0105] Preferably, in a method that can be implemented in this embodiment, the method for obtaining the temperature conversion rate of the medical thermal blanket for the second preset time period is: obtaining the difference between the maximum temperature and the minimum temperature of the patient in the initial preset time period as the second change value; negatively correlating the ratio of the second change value to the first change value as the conversion adjustment weight; the smaller the conversion adjustment weight, the larger the ratio of the second change value to the first change value, which indirectly reflects that the degree of change in the patient's body temperature is greater in the initial preset time period. In order to avoid excessive heating of the patient by the medical thermal blanket, the temperature conversion rate of the medical thermal blanket for the second preset time period should be smaller, and then the product of the initial conversion rate of the medical thermal blanket temperature and the conversion adjustment weight is used as the temperature conversion rate of the medical thermal blanket for the second preset time period.

[0106] Among them, the calculation formula of the temperature conversion rate of the medical thermal blanket in the second preset time period is: ; In the formula, f 2 is the temperature conversion rate of the medical thermal blanket in the second preset time period; 1 is the initial conversion rate of the temperature of the medical insulation blanket; △P 1 is the second change value; △W 1 is the first change value; Adjust weights for conversions.

[0107] It should be noted that It must be less than 1 because the temperature of the medical warming blanket cannot be fully transferred to the patient.

[0108] Step 6: Based on the set temperature of the medical thermal blanket in the second preset time period and the temperature conversion rate of the medical thermal blanket, obtain the set temperature of the medical thermal blanket in the third preset time period, and so on, obtain the set temperature of the medical thermal blanket in each preset time period, until the patient's body temperature in a certain preset time period is greater than the preset standard patient temperature, and turn off the medical thermal blanket.

[0109] In actual situations, if the patient's body temperature in the second preset time period is greater than the preset standard patient body temperature, it means that there is no abnormal low temperature in the patient's body temperature in the second preset time period, and the medical thermal blanket is turned off at this time; if the patient's body temperature in the second preset time period is still abnormally low in temperature, then according to the patient's body temperature and the medical thermal blanket temperature at each moment in the second preset time period, the medical thermal blanket set temperature of the second preset time period and the medical thermal blanket temperature conversion rate, step 3 is used to obtain the patient's warming degree in the second preset time period.

[0110] Among them, the specific method for obtaining the patient's warming degree in the second preset time period is: for any moment within the second preset time period, the difference between the set temperature of the medical thermal blanket in the second preset time period and the temperature of the medical thermal blanket at that moment is used as the temperature increase value of the medical thermal blanket at that moment; the product of the temperature increase value of the medical thermal blanket and the temperature conversion rate of the medical thermal blanket in the second preset time period is used as the patient's body temperature increase value at that moment; the addition of the patient's body temperature at that moment and the patient's body temperature increase value is used as the patient's predicted temperature at that moment; the difference between the patient's predicted temperature and the patient's body temperature at each moment in the second preset time period is accumulated, and the result of negative correlation and normalization is used as the patient's warming degree in the second preset time period.

[0111] According to the set temperature of the medical thermal blanket in the second preset time period and the degree of patient warming, as well as the temperature change of the medical thermal blanket in the second preset time period, step 4 is used to obtain the set temperature of the medical thermal blanket in the third preset time period.

[0112] Among them, the specific method for obtaining the set temperature of the medical thermal blanket for the third preset time period is: obtain the difference between the maximum temperature and the minimum temperature of the medical thermal blanket in the second preset time period as the third change value; obtain the difference between the patient warming degree in the second preset time period and the preset patient warming degree threshold as the third characteristic value; use the product of the third change value and the third characteristic value as the reference value for adjusting the temperature of the medical thermal blanket for the third preset time period; use the difference between the set temperature of the medical thermal blanket in the second preset time period and the reference value for adjusting the temperature of the medical thermal blanket as the set temperature of the medical thermal blanket for the third preset time period.

[0113] By analogy, the patient's body temperature is continuously monitored, and the set temperature of the medical thermal blanket for each preset time period is dynamically obtained, until the patient's body temperature within a preset time period is greater than the preset standard patient temperature, and the medical thermal blanket is turned off.

[0114] According to the dynamic adjustment of the set temperature of the medical thermal blanket in the above abnormal low temperature stage and the monitoring process of the patient's body temperature, the medical thermal blanket can timely and effectively maintain the patient's body temperature during surgery or treatment, effectively avoiding the abnormal low temperature of the patient during surgery or treatment, so that the set temperature of the medical thermal blanket can respond to the changes in the patient's body temperature in time. At the same time, the medical thermal blanket has the advantages of accurate temperature control, simple operation, safety and reliability, which effectively improves the success rate of surgery and treatment, as well as the quality and efficiency of medical services.

[0115] In summary, this embodiment obtains the patient's body temperature and the temperature of the medical thermal blanket; determines the abnormal low temperature stage based on the patient's body temperature and divides the preset time period, obtains the set temperature of the medical thermal blanket and the conversion rate of the medical thermal blanket temperature in the second preset time period according to the patient's body temperature, the temperature of the medical thermal blanket, the initial set temperature of the medical thermal blanket and the initial conversion rate of the temperature of the medical thermal blanket in the initial preset time period, and then obtains the set temperature of the medical thermal blanket in the third preset time period, and so on, obtains the set temperature of the medical thermal blanket in each preset time period, until the patient's body temperature in a certain preset time period is greater than the preset standard patient temperature, and the medical thermal blanket is turned off. This embodiment adaptively obtains the set temperature of the medical thermal blanket in each preset time period, responds to changes in the patient's body temperature in a timely manner, and effectively avoids the patient's body temperature from being too low.

[0120] The patient warming degree acquisition module 30 is used to divide the preset time period from the beginning of the abnormal low temperature stage, and obtain the patient warming degree of the initial preset time period according to the patient's body temperature and the medical thermal blanket temperature at each moment in the initial preset time period, the timely initial set temperature and the initial conversion rate of the medical thermal blanket temperature.
