[0033] In order to make the purposes, technical solutions and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0034] Embodiment one

[0035] Please refer to Figure 1 The rewarming rate adjusting method of the hypothermia therapeutic instrument comprises the steps of:

[0036] S10: obtaining a current body temperature change rate Vn, a target body temperature change rate Vm and a current body temperature Tn, and calculating a limiting water temperature Tx according to the current body temperature change rate Vn, the target body temperature change rate Vm and the current body temperature Tn;

[0037] S20: obtaining a target body temperature T0, and calculating a target water temperature Tm according to the target body temperature T0 and the current body temperature Tn;

[0038] S30: obtaining a current water temperature Ts, and calculating a water temperature adjusting duty cycle according to the current water temperature Ts and the target water temperature Tm or the limiting water temperature Tx; and

[0039] S40: adjusting the temperature of the hypothermia therapeutic instrument according to the water temperature adjusting duty cycle.

[0040] In the rewarming rate adjusting method of the hypothermia therapeutic instrument, since the parameters such as the current body temperature Tn, the current water temperature Ts and the current body temperature change rate Vn can be changed or actually set and adjusted, the finally output water temperature adjusting duty cycle can also be obtained through actual adjustment, and when the temperature is adjusted through the water temperature adjusting duty cycle, the body temperature rising rate of the hypothermia therapeutic instrument can be changed to be controllable, more use conditions can be met, and the application range of the hypothermia therapeutic instrument is improved.

[0041] The structure of the hypothermia therapeutic instrument in the embodiment of the present application can be the structure of a common existing hypothermia therapeutic instrument, that is, the hypothermia therapeutic instrument comprises a water tank, a water pump, a refrigeration / heat module, an ice blanket, an ice cap, and a liquid circulating device for supplying liquid to the ice blanket and the ice cap, the water outlet of the water tank, the water pump, the refrigeration / heat module, the liquid circulating device, and the water inlet of the water tank are sequentially connected by pipelines; the output end of the refrigeration / heat module is connected with the water inlet adapter by a pipeline, and the water inlet of the water tank is connected with the water outlet adapter by a pipeline. In addition to being capable of performing the rewarming rate adjustment method of the hypothermia therapeutic instrument described above, the hypothermia therapeutic instrument in the embodiment of the present application also has the common functions of the existing hypothermia therapeutic instrument, which will not be described here.

[0042] Specifically, please refer to Figure 6 The hypothermia therapeutic instrument in the embodiment of the present application is provided with a main controller and a secondary controller electrically connected with the main controller, two temperature probes electrically connected with the main controller and the secondary controller respectively are arranged on the ice blanket, the two temperature probes are respectively a first temperature probe for acquiring the current temperature of a patient, that is, for acquiring the current body temperature Tn, and a second temperature probe for acquiring the current temperature of the water blanket, that is, for acquiring the current water temperature Ts, the first temperature probe acquires the current body temperature Tn every t0 time, and sends the acquired current body temperature Tn to the main controller, and the second temperature probe acquires the current water temperature Ts every t0 time, and sends the acquired current water temperature Ts to the secondary controller.

[0043] In the embodiment, the main controller and the secondary controller are preset with a time interval in advance, wherein the time interval for detecting the current body temperature Tn is consistent with the time interval for detecting the current water temperature Ts.

[0044] It is worth mentioning that, in the actual measurement process, the current body temperature Tn and the current water temperature Ts measured by the temperature probes can have errors, and the current body temperature Tn and the current water temperature Ts can fluctuate up and down within a certain range of the actual temperature, and the fluctuation range is ±0.3℃ of the actual temperature, but for brief calculation, the temperatures collected by the first temperature probe and the second temperature probe are still calculated.

[0045] In one embodiment, the first temperature probe can be controlled to work intermittently by the main controller, so that the first temperature probe detects the current body temperature Tn only when it is controlled to work, and the second temperature probe can be controlled to work intermittently by the secondary controller, so that the second temperature probe detects the current water temperature Ts only when it is controlled to work, so as to reduce the working time of the two temperature probes and avoid heating caused by long-time work.

[0046] In step S10, the target body temperature T0 and the target body temperature change rate Vm are preset in the main controller in advance; the current body temperature Tn obtained by the first temperature probe is sent to the main controller, and the current body temperature change rate Vn is calculated by the main controller, wherein the main controller calculates the limiting water temperature Tx according to the current body temperature change rate Vn, the target body temperature change rate Vm and the current body temperature Tn.

[0047] Specifically, the calculation formula of the limiting water temperature Tx is Tx=Tn+∑(Vm-Vn)*S, wherein Tn is the current body temperature, Vm is the target body temperature change rate, Vn is the current body temperature change rate, and S is a coefficient, which can be a constant, for example, S can be set to 3. The coefficient can be determined according to the clinical requirements, which is not limited herein. By adjusting the size of S, the size of the limiting water temperature Tx can be adjusted, so as to achieve the purpose of controlling the water temperature adjustment duty cycle.

[0048] In addition, the target body temperature change rate Vm is usually set to 0.25℃ / h, which is one of the values in the embodiment and does not limit the embodiment. Generally, the target body temperature change rate Vm can be changed and adjusted according to the situation.

[0049] In step S20, the current body temperature Tn obtained by the first temperature probe is sent to the main controller, the preset target body temperature T0 is obtained in the main controller, and the target water temperature Tm is calculated according to the current body temperature Tn and the target body temperature T0.

[0050] In step S30, the current water temperature Ts obtained by the second temperature probe is sent to the sub-controller, and the value of the target water temperature Tm and the value of the limiting water temperature Tx are sent to the sub-controller, and then the water temperature adjustment duty cycle is calculated according to the current water temperature Ts and the target water temperature Tm, or the current water temperature Ts and the limiting water temperature Tx.

[0051] It should be noted that the current water temperature Ts is used to calculate the water temperature adjustment duty cycle with the target water temperature Tm or the limiting water temperature Tx. The size of the target water temperature Tm and the limiting water temperature Tx is determined by comparing the values of the target water temperature Tm and the limiting water temperature Tx. The smaller value is sent to the sub-controller for calculation to obtain the water temperature adjustment duty cycle.

[0052] In step S40, the water temperature adjustment duty cycle is sent to the actuator, and the actuator adjusts the temperature of the hypothermia therapy instrument according to the water temperature adjustment duty cycle.

[0053] In the embodiment of the present application, the water temperature adjustment duty cycle is calculated according to the current water temperature Ts and the target water temperature Tm, and the target water temperature Tm is calculated according to the target body temperature T0 and the current body temperature Tn. The current body temperature Tn can be directly obtained from the patient, and the target body temperature T0 can be preset in advance. Therefore, the target water temperature Tm can be adjusted by adjusting the value of the target body temperature T0, and the water temperature adjustment duty cycle can be adjusted. At the same time, the current body temperature Tn will also gradually rise during the rewarming process, which will further affect the water temperature adjustment duty cycle.

[0054] Or it can be understood that the water temperature adjustment duty cycle calculated according to the current water temperature Ts and the limit water temperature Tx is calculated according to the current body temperature change rate Vn, the target body temperature change rate Vm and the current body temperature Tn. The target body temperature change rate Vm is preset in advance, and the limit water temperature Tx can be adjusted by adjusting the target body temperature change rate Vm, and the water temperature adjustment duty cycle can be adjusted. At the same time, the current body temperature Tn will also gradually rise during the rewarming process, and the current body temperature change rate Vn will change, which will further affect the water temperature adjustment duty cycle.

[0055] Embodiment two

[0056] Further, please refer to Figure 2 , Figure 2 is a flow chart of a specific implementation of the step S10 of the rewarming rate adjustment method of the hypothermia treatment instrument in the embodiment of the present application. The current body temperature change rate Vn is obtained by the following steps:

[0057] S01: obtain the current body temperature Tn every preset time t0; and

[0058] S02: calculate the current body temperature change rate Vn according to the current body temperature Tn, the last body temperature T(n-1) and the preset time t0.

[0059] In step S01, the preset time t0 is preset in the controller in advance. For example, the preset time t0 can be set to 0.5h. The two temperature probes arranged on the water blanket measure the current body temperature Tn and the current water temperature Ts every 0.5h. The value is only illustrative and does not limit the present application.

[0060] In step S02, specifically, the calculation formula of the current body temperature change rate Vn is:

[0061] (Tn-T(n-1)) / t0.

[0062] For example, assuming the current body temperature Tn is 36℃, the last body temperature T(n-1) is 36.1℃, and the preset time t0 is 0.5h, then the current body temperature change rate Vn is calculated according to the above formula, and the current body temperature change rate Vn is 0.2℃ / h.

[0063] It is worth mentioning that, due to the error of the measured current body temperature Tn, the current body temperature change rate Vn will fluctuate up and down within a certain range of the actual rate, and the fluctuation range is target rate±0.1℃ / h.

[0064] Example Three

[0065] Further, please refer to Figure 3 , Figure 3 is a flow chart of a specific embodiment of step S20 in the rewarming rate adjusting method of the hypothermia treatment instrument of the present application, wherein step S21 is a specific embodiment of step S20, and the specific steps of S21 are as follows:

[0066] S21: obtaining the target body temperature T0, and calculating the target water temperature Tm according to the target body temperature T0 and the current body temperature Tn through the body temperature PID algorithm.

[0067] In step S21, the target body temperature T0 is preset in the main controller, and the current body temperature Tn is sent to the main controller through the temperature probe. In this embodiment, the body temperature PID algorithm adopts a positional PID algorithm, and the target water temperature Tm is calculated through the body temperature PID algorithm. The calculation formula of the target water temperature Tm is as follows:

[0068]

[0069] Wherein, Δu(k) is the target water temperature Tm, e(k) is the current temperature difference, specifically, e(k) = T0-Tn, e(k-1) is the last temperature difference, Kp is the proportional coefficient, Kd is the differential coefficient, and Ki is the integral coefficient, which can be set according to actual requirements, is the cumulative error.

[0070] Example Four

[0071] Further, please refer to Figure 4 and Figure 6 , Figure 4 is a flow chart of a specific embodiment of step S30 in the rewarming rate adjusting method of the hypothermia treatment instrument of the present application, wherein steps S31 and S32 are a specific embodiment of step S30, and the specific steps of step S30 are as follows:

[0072] S31: obtaining the current water temperature Ts every preset time; and

[0073] S32: calculating the water temperature adjustment duty cycle according to the current water temperature Ts and the target water temperature Tm or the limiting water temperature Tx through a water temperature PID algorithm.

[0074] In step S31, the preset time is preset in advance in the controller, for example, the preset time can be set to 0.5h, and the current water temperature Ts is obtained every 0.5h, which can be equal to the interval preset time t0 of obtaining the current body temperature Tn.

[0075] In step S32, the water temperature PID algorithm adopts a position type PID algorithm, and specifically, the calculation method of the water temperature adjustment duty cycle is as follows:

[0076]

[0077] Wherein, Δu(k) is the water temperature adjustment duty cycle, e(k) is the current water temperature difference, specifically, e(k) = Tm-Ts, e(k-1) is the last water temperature difference, Kp is the proportional coefficient, Kd is the differential coefficient, and Ki is the integral coefficient, which can be set according to actual requirements, is the cumulative error.

[0078] For example, assuming that the target water temperature Tm is 36℃, the current water temperature Ts is 31℃, the first water temperature difference is the current water temperature difference e(k) equal to 5℃, at this time, assuming that the current water temperature Ts is 31.5℃ in the second measurement, e(k-1) is equal to e(k) is equal to 5℃, the second water temperature difference is the current water temperature difference e(k) is equal to 4.5℃, and so on.

[0079] In this embodiment, since the water temperature adjustment duty cycle is calculated according to the current water temperature Ts and the target water temperature Tm, the target water temperature Tm is calculated according to the target body temperature T0 and the current body temperature Tn, and the target body temperature T0 can be preset in advance, therefore, when the target body temperature T0 is unchanged and the current body temperature Tn changes, if the current body temperature Tn increases, the target water temperature Tm decreases, that is, the output water temperature adjustment duty cycle decreases, and vice versa, the water temperature adjustment duty cycle increases.

[0080] Of course, the water temperature adjustment duty cycle can also be adjusted by adjusting the value of the target body temperature T0, when the target body temperature T0 changes and the current body temperature Tn is unchanged, if the target body temperature T0 increases, the target water temperature Tm increases, that is, the water temperature adjustment duty cycle decreases, and vice versa, the water temperature adjustment duty cycle increases.

[0081] From another aspect, since the water temperature adjustment duty cycle is calculated according to the current water temperature Ts and the limit water temperature Tx, the limit water temperature Tx is calculated according to the current body temperature change rate Vn, the target body temperature change rate Vm and the current body temperature Tn, and the target body temperature change rate Vm is preset in advance, if the current body temperature Tn gradually rises, the current body temperature change rate Vn makes the limit water temperature Tx value smaller, that is, the water temperature adjustment duty cycle becomes smaller.

[0082] It should be noted that in the embodiment, the body temperature PID algorithm and the water temperature PID algorithm are the same calculation formula, and both output a value without unit, but the coefficients used in the body temperature PID algorithm and the water temperature PID algorithm are different, and need to be converted and added with corresponding units to become the target water temperature Tm and the water temperature adjustment duty cycle.

[0083] Embodiment five

[0084] Further, please refer to Figure 5 , step S32 comprises steps of:

[0085] S321: judging the size relationship between the target water temperature Tm and the limit water temperature Tx;

[0086] S322: if the target water temperature Tm is greater than the limit water temperature Tx, calculating the water temperature adjustment duty cycle through the water temperature PID algorithm according to the current water temperature Ts and the limit water temperature Tx; and

[0087] S323: if the target water temperature Tm is smaller than or equal to the limit water temperature Tx, calculating the water temperature adjustment duty cycle through the water temperature PID algorithm according to the current water temperature Ts and the target water temperature Tm.

[0088] In step S321, the main controller calculates the limit water temperature Tx and sends the limit water temperature Tx to the secondary controller, the target water temperature Tm is preset in advance in the secondary controller, and the size of the target water temperature Tm and the limit water temperature Tx is judged through the algorithm in the secondary controller.

[0089] If the target water temperature Tm is greater than the limit water temperature Tx, step S322 is entered, the current water temperature Ts is obtained every preset time, and the water temperature adjustment duty cycle is calculated through the water temperature PID algorithm according to the current water temperature Ts and the limit water temperature Tx.

[0090] If the target water temperature Tm is smaller than or equal to the limit water temperature Tx, step S323 is entered, the current water temperature Ts is obtained every preset time, and the water temperature adjustment duty cycle is calculated through the water temperature PID algorithm according to the current water temperature Ts and the target water temperature Tm.

[0091] Because the water blanket itself has residual temperature or heating inertia when in use, and has a certain temperature rise under the influence of residual temperature or the action of heating inertia, by comparing the target water temperature Tm with the limiting water temperature Tx, and selecting the smaller value to be substituted into the water temperature PID algorithm, the temperature can be prevented from being too high, and after comparison and selection, the temperature can meet the actual use requirements of the patient, the body temperature will not be too high, and the heating time of the water blanket can be shortened.

[0092] In the embodiment, the value of the limiting water temperature Tx can be adjusted by first adjusting the values of the self-set target body temperature change rate Vm and the constant S. Because the controller will calculate the water temperature adjustment duty cycle by selecting the smaller value between the limiting water temperature Tx and the target water temperature Tm and the current water temperature Ts, to adjust the temperature of the hypothermia therapeutic instrument.

[0093] Therefore, if the value of the limiting water temperature Tx is adjusted to be smaller by the target body temperature change rate V or the constant S, when the limiting water temperature Tx is compared with the target water temperature Tm, the controller will always select the limiting water temperature Tx, and the water temperature adjustment duty cycle calculated by the limiting water temperature Tx and the current water temperature Ts will be smaller, so that the rate of the patient's body temperature rise can be slowed down when temperature control is performed, the body temperature rise can be avoided, and the patient's body temperature can be kept relatively stable.
