All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for adjusting a human body temperature, which is applied to a sub-low temperature therapy device, and in particular, referring to fig. 1, fig. 1 is a schematic diagram illustrating a feedback of temperature adjustment of the sub-low temperature therapy device in the embodiment of the present invention, in fig. 1, the sub-low temperature therapy device includes a main controller 10, a sub-controller 20, a semiconductor temperature control component 30, a water outlet 40 of a water circulation system, and a water blanket 50, and the main controller 10, the sub-controller 20, and the semiconductor temperature control component 30 are sequentially connected, and the semiconductor temperature control component 30 is used for adjusting a water temperature in the water circulation.

Wherein, a temperature sensor is preset at the water outlet of the water circulation system and is used for detecting the temperature of the water outlet; in addition, the sub-hypothermia treatment apparatus is also preset with a temperature sensor for detecting the body temperature of the patient.
Further, referring to fig. 2, fig. 2 is a schematic flow chart of a method for adjusting human body temperature according to an embodiment of the present invention, in which the method includes:
The sub-hypothermia treatment equipment mainly has two treatment modes: the two modes of sub-hypothermia treatment and normal body temperature management are both required to set a target body temperature value for a user. That is, the controlled object of the method is a patient, and the controlled quantity is the body temperature of the patient. The main controller is used for receiving a target body temperature value input by a user and outputting the target water temperature value to the sub-controller according to logical reasoning.
In this embodiment, in the use process of the sub-hypothermia treatment apparatus, a closed-loop feedback adjustment loop may be formed between the patient and the main controller, the body temperature value of the patient is detected first, and when an error between the detected body temperature value and a target body temperature value in the main controller is greater than a first preset threshold (e.g., 0.3 ℃), an adjustment signal may be sent to the main controller, and the adjustment signal may be used to adjust a target water temperature value output by the main controller to the sub-controller.
Specifically, the main controller outputs a reasonable target water temperature value to the sub-controller after logical reasoning according to the target body temperature value and the first regulating signal, that is, the target water temperature value is dynamically adjusted along with the change of the body temperature value of the patient in the treatment process.
The output of the main controller is the input of the sub-controller, and for the sub-controller, the sub-controller is mainly used for adjusting the working mode and power of the semiconductor temperature control assembly according to the input target water temperature value, so that the temperature value of the water circulation system is indirectly adjusted.
In this embodiment, in the use process of the sub-low temperature treatment device, a closed-loop feedback adjustment loop is also formed between the water outlet and the sub-controller, the water temperature value of the water outlet is detected first, when an error between the detected water temperature value and a target water temperature value in the sub-controller is greater than a first preset threshold (e.g., 0.3 ℃), an adjustment signal is sent to the sub-controller, the adjustment signal can be used for adjusting a control signal output by the sub-controller to the semiconductor temperature control assembly, the control signal is used for controlling the working mode and power of the semiconductor temperature control assembly, and the body temperature value of the patient is adjusted by adjusting the water temperature value of the water circulation system.
The semiconductor temperature control assembly can adopt a semiconductor refrigeration piece, two surfaces of the semiconductor refrigeration piece are marked as an A surface and a B surface, forward current is conducted, the A surface is a hot end, and the B surface is a cold end; and (4) reverse current is supplied, wherein the surface A is a cold end, and the surface B is a hot end. In this embodiment, can paste the radiator in the one side of semiconductor refrigeration piece, the aluminium module is pasted to the another side, and the inside passageway of aluminium module is flowed through to the circulating water, is heated or refrigerates, as long as the direction of change electric current, can be in order to realize the heating or the refrigeration control to the circulating water. Because the circulating water does not directly contact with the patient, but flows through the water blanket, the water blanket can be used as a heat exchange medium after wrapping the patient. If the temperature of the water in the water blanket is lower than the body temperature of the patient, the body temperature of the patient is reduced; conversely, if the temperature of the water in the water blanket is higher than the patient's body temperature, the patient's body temperature may be raised.
It is understood that the above steps 201 and 202 are not in a time sequence relationship, that is, the step 201 may be executed first and then the step 202 is executed, the step 202 may be executed first and then the step 201 is executed, or the step 201 and the step 202 may be executed simultaneously.
The human body temperature adjusting method provided by the embodiment of the invention realizes the control of the body temperature of the patient by means of body temperature feedback adjustment and water temperature feedback adjustment, has high control sensitivity, can accurately improve or reduce the body temperature of the patient, and can effectively reduce the volume of the sub-low temperature treatment equipment and reduce noise and power consumption in the using process by adjusting the temperature by using the semiconductor temperature control component.
Further, based on the foregoing embodiment, referring to fig. 3, fig. 3 is a detailed flowchart of a human body temperature adjustment method in the embodiment of the present invention, in this embodiment, before sending the first adjustment signal to the main controller in step 201, the method further includes:
step 301, determining a feedback adjustment parameter according to the error between the detected body temperature value and the target body temperature value.
In this embodiment, in order to adjust the body temperature value of the patient more quickly and accurately, the feedback adjustment parameter may be determined according to the error between the detected body temperature value and the target body temperature value, and then the temperature adjustment value corresponding to the sub-controller may be calculated according to the determined feedback adjustment parameter. Wherein, the error is bigger, and the regulation dynamics is also bigger, and the error is smaller, and the regulation dynamics also can be smaller.
The feedback regulation parameters comprise a proportionality coefficient kp, an integral coefficient ki and a differential coefficient kd.
And 302, calculating a first temperature adjusting value corresponding to the sub-controller based on the determined feedback adjusting parameter.
After determining the feedback adjustment parameter, the temperature adjustment value corresponding to the sub-controller may be calculated according to the following formula:
Δu(k)＝kp*[e(k)-e(k-1)]+ki*e(k)+kd*[e(k)-2*e(k-1)+e(k-2)]
wherein e (k) represents the corresponding error in the current adjustment, e (k-1) represents the corresponding error in the last adjustment, and e (k-2) represents the corresponding error in the last adjustment.
Step 303 is to generate the first adjustment signal according to the calculated first temperature adjustment value.
After the first adjusting signal is sent to the main controller, the target water temperature value of the sub-controller can be adjusted to the first temperature adjusting value according to the preset temperature adjusting gradient value.
When the body temperature value is larger than the target body temperature value, reducing the target water temperature value of the sub-controller to a first temperature regulation value according to a preset temperature reduction gradient value; and when the body temperature value is smaller than the target body temperature value, according to a preset temperature rising gradient value, the target water temperature value of the sub-controller is raised to a first temperature regulation value.
For example, when the calculated target water temperature value is 40 ℃ and the current water temperature value is 42 ℃, the current water temperature value may be reduced to 41 ℃ and then to 40 ℃. Wherein the temperature can be rapidly reduced from 42 ℃ to 41 ℃ in a short time (such as 1 minute) and slowly reduced from 41 ℃ to 40 ℃ in a long time (such as 2 minutes).
Further, based on the foregoing embodiment, referring to fig. 4, fig. 4 is another detailed flowchart of the human body temperature adjustment method in the embodiment of the present invention, in this embodiment, before sending the second adjustment signal to the sub-controller described in step 202, the method further includes:
For example, assuming that the first preset threshold is 0.2 ℃, then:
when the temperature of 0.2 ℃ is lower than the target temperature-the current temperature is lower than 0.5 ℃, adopting a feedback adjustment parameter 1: kp1, ki1, kd 1;
when the temperature is more than or equal to 0.5 ℃ and the target water temperature value-the current water temperature value is less than 1 ℃, adopting a feedback adjustment parameter 2: kp2, ki2, kd 2;
when the temperature is more than or equal to 1 ℃ and the target water temperature value-the current water temperature value is less than 1.5 ℃, adopting a feedback adjustment parameter 3: kp3, ki3, kd 3;
when the temperature is more than or equal to 1.5 ℃ and the target water temperature value-the current water temperature value is less than 2 ℃, adopting a feedback adjustment parameter 4: kp4, ki4, kd 4;
when the temperature is more than or equal to 2 ℃ and the target water temperature value-the current water temperature value is less than 2.5 ℃, adopting a feedback adjustment parameter 5: kp5, ki5, kd 5;
when the temperature is more than or equal to 2.5 ℃ and the target water temperature value-the current water temperature value is less than 3 ℃, adopting a feedback adjustment parameter 6: kp6, ki6, kd 6;
when the temperature is less than or equal to 3 ℃ and the target water temperature value-the current water temperature value is less than or equal to 3 ℃, the semiconductor temperature control component works at the maximum power.
And 402, calculating a second temperature adjusting value corresponding to the semiconductor temperature control component based on the determined feedback adjusting parameter.
After the second adjusting signal is sent to the sub-controller, the control signal output to the semiconductor temperature control assembly by the sub-controller can be adjusted according to the preset temperature adjusting gradient value.
Specifically, when the water temperature value is greater than the target water temperature value, the power of the semiconductor temperature control assembly is reduced according to a preset temperature reduction gradient value, or the working mode of the semiconductor temperature control assembly is switched from a heating mode to a cooling mode; and when the water temperature value is smaller than the target water temperature value, increasing the power of the semiconductor temperature control assembly according to a preset temperature rising gradient value, or switching the working mode of the semiconductor temperature control assembly from a cooling mode to a heating mode.
The principle adopted in the steps 401 to 403 is the same as that adopted in the steps 301 to 303, and reference may be specifically made to the steps 301 to 303, which is not described herein again.
For a better understanding of the embodiment of the present invention, referring to fig. 5, fig. 5 is a graph illustrating a variation curve of water temperature of a water circulation system and a body temperature of a patient according to the embodiment of the present invention. In the embodiment of the invention, assuming that the body temperature value of the patient using the sub-hypothermia treatment device which is detected at the beginning is 33 ℃ and the target body temperature value is 36.5 ℃, a first adjusting signal is sent to the main controller and is used for adjusting the target water temperature value output to the sub-controller by the main controller, and in the embodiment, the target water temperature value of the sub-controller is adjusted to 40.5 ℃; and detecting the water temperature value of the water outlet of the water circulation system, and sending a second adjusting signal to the secondary controller if the detected water temperature value is 30 ℃, wherein the second adjusting signal is used for adjusting a control signal output by the secondary controller to the semiconductor temperature control assembly, the adjusted control signal is used for adjusting the semiconductor temperature control assembly to a heating mode, and the power of the semiconductor temperature control assembly is increased until the water temperature value of the water outlet of the water circulation system reaches 40.5 ℃.
