Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment control, in particular to a temperature and humidity control method of an incubator and related device. BACKGROUND

[0002] The incubator is an important medical equipment for providing appropriate treatment and care environment for newborns. In the incubator, reasonable setting and adjustment control of temperature and humidity are crucial for the maintenance of the body function of newborns. When treating premature infants born before full term, higher requirements are placed on the control of temperature and humidity of the incubator. The incubator needs to provide absolutely high humidity to simulate the amniotic fluid environment of the baby in the mother's body and maintain a suitable temperature to protect the health of the baby.

[0003] However, the traditional incubator only considers the heating treatment of the box in a suitable humidity environment, and ignores the temperature control effect in a high humidity environment. In a high humidity environment, the heat of the humidifying block will affect the overall temperature of the box, and the heat conduction performance of the air will also change, resulting in high heat. When the temperature of the humidifying block and the temperature of the box are too high, the traditional algorithm for controlling temperature and humidity will be out of adjustment. Even if the power output of the corresponding heating and humidifying is turned off, the temperature will continue to rise, accumulating a large amount of heat, so that the temperature is much higher than the target temperature set by the control, resulting in over-temperature phenomenon, which greatly affects the treatment and care effect on the baby.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0024] In this paper, the term "embodiment" means that the specific features, structures or properties described in conjunction with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0025] The present application provides a temperature and humidity control method of an incubator, referring to Figure 1 , Figure 1 is a flowchart of an embodiment of the temperature and humidity control method of the incubator provided in the present application. The temperature and humidity control method of the incubator comprises the following steps.

[0026] Step 10: Obtain the target humidity of the incubator and the threshold working temperature of the humidifying block when the humidity in the incubator is the preset humidity division value, and collect the current humidity of the incubator and the current working temperature of the humidifying block. The preset humidity division value is used to distinguish between high humidity and low humidity.

[0027] When controlling the incubator, the corresponding target humidity is set, which is usually determined according to the theoretical appropriate temperature of the baby's treatment or care, or the appropriate environmental conditions under the comprehensive consideration of temperature, light, oxygen content, etc. The threshold working temperature of the humidifying block at the preset humidity division value of the incubator is the temperature of the humidifying block detected and recorded at the corresponding preset humidity division value, which is usually selected as a temperature value when the humidifying block temperature and the incubator temperature are maintained at a steady state. The threshold working temperature can be determined in advance, determined according to historical measurement values, or determined in real time by contacting the temperature sensor of the humidifying block when the control is performed in this scheme. Since the preset humidity division value is usually selected under temperature control conditions, the threshold working temperature is usually a determined and controlled value under the same humidity environment of the same incubator.

[0028] In order to ensure the real-time effectiveness of the subsequent temperature and humidity control of the incubator, the current humidity of the incubator and the current working temperature of the humidifying block need to be collected in real time. The humidity and temperature can be collected by humidity sensors and temperature sensors respectively, so that the real-time current humidity in the incubator and the current working temperature of the humidifying block under the current humidity can be obtained. The current humidity can reflect the humidity environment in the incubator, and the current working temperature can reflect the temperature control performance of the humidifying block, which is beneficial to avoid over-temperature in subsequent steps.

[0029] The preset humidity division value is a relative humidity value. When the humidity in the incubator is at or below this value, the temperature of the incubator and the temperature of the humidifying block can be within a relatively controlled range, which can be controlled and adjusted by traditional PID algorithm, fuzzy control algorithm, neural network prediction algorithm, etc. The value can be different for different structures and environmental conditions of the incubator. The value can be verified according to the experiment, or selected according to the temperature control performance of the humidifying block and the definition range of the corresponding control algorithm, or selected according to the empirical value.

[0030] Preferably, the preset humidity division value is 85% RH (Relative Humidity). In the clinical treatment of infants, the humidity of 85% RH is at a relatively high humidity, which is conducive to the protection of the body function of the infant, maintains the skin of the infant moist and the respiratory tract comfortable, and can also avoid the problems of mold breeding and bacterial breeding caused by excessive humidity. The temperature of the humidifying block and the temperature of the incubator can also be effectively controlled at this humidity, thereby ensuring the corresponding temperature control. Therefore, setting the preset humidity division value at about 85% RH can effectively divide the high humidity range and the low humidity range.

[0031] In the control process of the traditional incubator, only the case of being lower than the preset humidity division value is considered, i.e., the low humidity range defined in the present scheme. In this range, when the incubator is working, the humidifying block is usually not turned on or is only humidified to 50% RH to 70% RH, which is the appropriate environmental humidity for healthy newborns. For infants with different functions, the humidification is at most about 90% RH. However, since there is no corresponding cooling measure for the humidifying block when the humidity is higher than 85% RH by a certain value, the humidification to 90% RH cannot avoid the occurrence of over-temperature disorder. Moreover, the control method of the traditional incubator does not consider the temperature control condition for treating special newborns such as premature infants born before 1.5 Kg, premature infants with body damage, etc. in the incubator, i.e., the traditional incubator usually does not consider the control of the temperature and humidity for treatment. In such special cases, an absolutely high humidity is needed to simulate the amniotic fluid environment of the infant in the mother's body, maintain the health of the infant's body, and have a higher requirement for humidity, i.e., the environmental humidity is generally higher than 85% RH or even 95% RH, i.e., the high humidity range defined in the present scheme. In the high humidity range, the traditional incubator control method cannot well control the related temperature, and the temperature of the humidifying block and the accumulation of heat in the incubator are not conducive to the treatment of such newborns. However, the present scheme can realize the temperature control of the incubator in the high humidity range through the following steps.

[0032] The above steps obtain the target humidity, the preset humidity division value, the threshold working temperature, and the real-time collected current humidity and current working temperature, etc. to provide data support for the subsequent temperature and humidity control. By setting the preset humidity division value, the humidity range is divided into a high humidity range and a low humidity range, so that the control method is more targeted and flexible, can meet the needs of the temperature and humidity control of the incubator in different situations, is conducive to the subsequent targeted treatment of different humidity and temperature situations, thereby realizing the control optimization of the temperature and humidity of the infant growth environment, improving the safety and comfort of the infant care environment, and being conducive to the subsequent treatment of the infant.

[0033] Step 20: Determine the humidity interval of the target humidity based on the size relationship between the target humidity and the preset humidity division value.

[0034] On the basis of the foregoing, the temperature interval in which the temperature is located can be determined by comparing the size of the obtained target humidity and the preset humidity division value. For example, the preset humidity division value is set to 85 RH. If the incubator needs to be used for the treatment of a newborn in the special case as in the above example, the target humidity can be set to 95% RH. Since it is greater than the preset humidity division value, it can be determined that the target humidity is in the high humidity interval. If the incubator only needs to provide a suitable humidity environment for a relatively healthy newborn, the target humidity can be set to 60% RH. Since it is less than the preset humidity division value, it can be determined that the target humidity is in the low humidity interval. It should be noted that when the target humidity and the preset humidity division value are the same, they can be considered to be in any humidity interval or in the interval corresponding to the same value, which is determined in advance. The specific determination depends on the actual application requirements and settings.

[0035] By determining the humidity interval of the target humidity through this step, the humidity environment can be divided into a high humidity interval and a low humidity interval according to the current needs of the incubator, providing a clear control direction and strategy for subsequent temperature and humidity control. This is conducive to using different control methods according to different humidity intervals, thereby better meeting the growth environment and treatment needs of the baby. At the same time, by dividing the humidity interval, the control method can be more targeted and flexible, improving the accuracy and efficiency of temperature and humidity control and ensuring the safety and comfort of the baby.

[0036] Step 30: When the target humidity is in the high humidity interval and the current working temperature is higher than the threshold working temperature, stop the power output of the humidifying block to utilize the residual heat of the humidifying block to drive the current humidity to rise.

[0037] When the target temperature is in the high humidity interval, the humidity in the incubator will gradually increase or remain in the high humidity interval. In order to maintain stable humidity control in this high humidity interval, the humidifying block under the traditional control method needs to continuously output high power, thereby generating high heat. Under this condition, the humidifying block will accumulate a large amount of heat and diffuse the heat in the incubator. For example, the heat will be continuously transported to the upper part of the bed body through the ventilation system of the incubator, causing abnormal temperature control of the incubator and further causing the loss of temperature control of the heating block. When the humidity reaches a steady state, the temperature of the humidifying block will be too high, and the temperature in the incubator will be much higher than the preset target temperature, resulting in over-temperature. This situation is extremely unfavorable for the treatment of newborns.

[0038] In order to solve the problem of over-temperature due to temperature adjustment in the high humidity range, the power output of the humidifying block is stopped when the current working temperature of the humidifying block reaches the threshold working temperature. The threshold working temperature is within a controlled range, and a relatively high humidity value can be achieved at this temperature. Even if it is set in the high humidity range, a certain amount of heat accumulation is needed to reach the threshold working temperature in the steady state. Therefore, when the target humidity of the incubator is in the high humidity range and the current working temperature is at the threshold working temperature, a relatively high humidity can be obtained. For example, in some incubators, the preset humidity division value is set to 85% RH, and the corresponding threshold working temperature is 50°C. At the steady-state threshold working temperature, the temperature in the incubator is stable at a treatment temperature of about 30°C. If the target humidity is set to 95% RH, the current humidity can reach 90% RH when the current working temperature reaches 50°C during the process of adjusting the current humidity to approach the target humidity.

[0039] Under the condition that the current working temperature reaches the threshold working temperature, the power output of the humidifying block is stopped. On the one hand, it can keep the working temperature within a controllable range to avoid over-temperature. On the other hand, after the humidifying block is turned off, there is still residual heat, which can continue to drive the evaporation of water molecules or other specific liquid molecules in the incubator, thereby increasing the humidity in the incubator. In this process, although the control of reaching the corresponding target humidity is slowed down to some extent, the heat accumulation of the humidifying block and the incubator body is reduced, and the over-temperature phenomenon is avoided. At the temperature of the residual heat, the temperature of the incubator body is usually at a high evaporation rate level, and since the incubator usually has good air flow and sealing properties, it is not easy to cause humidity saturation and difficulty in increasing the humidity. Therefore, the humidity can be continuously increased to approach the target humidity.

[0040] Through the above steps, when the target humidity is in the high humidity range and the current working temperature is higher than the threshold working temperature, the power output of the humidifying block is stopped to utilize the residual heat of the humidifying block to drive the humidity to rise, improving the accuracy and efficiency of temperature and humidity control. It can avoid over-temperature of the humidifying block and maintain the humidity environment in the incubator using residual heat, achieving balanced control of temperature and humidity. At the same time, this step can achieve temperature and humidity control in the incubator without additional energy consumption, reducing control cost and resource consumption. It is beneficial to provide a safer and more suitable environment for the treatment and care of newborns.

[0041] Step 40: Obtain the target temperature of the incubator and collect the current temperature of the incubator.

[0042] The target temperature of the incubator is usually set by the user or recommended according to the health status and growth needs of the baby. After obtaining the target temperature, the system further collects the current temperature of the incubator, which is usually achieved by a temperature sensor that monitors the current temperature inside the incubator in real time and feeds back the current temperature. The corresponding temperature control algorithm, system or model can control the temperature according to the current temperature and the target temperature.

[0043] Step 50: When the target humidity is in the high humidity interval and the current temperature is in the preset temperature interval close to the target temperature, the output power of the heating block is adjusted based on the difference between the current temperature and the target temperature.

[0044] When the target humidity is in the high humidity interval, the incubator still needs to maintain temperature control to meet the corresponding treatment needs. The heating process needs to be heated by the heating block, and the output power of the heating block needs to be adjusted by a specific algorithm to ensure smooth and comfortable temperature conversion to reach the corresponding target temperature. In the high humidity interval, the heat accumulated by the humidifying block is usually sufficient to reach the target temperature, and maintaining the temperature control under normal humidity conditions will cause the temperature to be higher than the target temperature, which requires additional heat dissipation, resulting in additional resource consumption.

[0045] On this basis, the output power of the heating block under normal output logic can be attenuated to avoid the current temperature being higher than the target temperature. The attenuation adjustment adjusts the output power of the heating block, and when it is in the preset temperature interval, the closer it is to the target temperature, the more the output power is attenuated. Through continuous attenuation adjustment, the accumulated heat of the heating block and the accumulated heat and dissipated heat of the humidifying block reach a relatively balanced value, and the temperature in the incubator is finally maintained at the target temperature to provide a corresponding treatment or care environment.

[0046] The preset temperature interval is usually a temperature range determined according to experience or experiment, which represents an interval in which the current temperature is close to the target temperature, and the output of the heating block is attenuated in the interval, so that the heat in the incubator gradually stabilizes and finally maintains at a temperature close to the target temperature. The random attenuation adjustment in the preset temperature interval can be a multiple adjustment, for example, the output power is changed to a multiple of the original output power in the interval, and the multiple is set to a multiple value less than 1; the preset temperature interval can also be attenuated by a preset attenuation function, for example, the attenuation function can be a linear function, a segmented function or an exponential function, so that the output power of the heating block gradually decreases, thereby gradually stabilizing the temperature in the incubator. In addition, the corresponding attenuation coefficient can be predicted by a neural network under the preset temperature interval, or a port for controlling and adjusting the attenuation coefficient is provided.

[0047] Optionally, referring to Figure 2 , the output power of the heating block is attenuated based on the difference temperature between the current temperature and the target temperature, which can be performed according to the following steps:

[0048] Step 51: Calculate the difference temperature between the current temperature and the target temperature.

[0049] Step 52: Confirm the difference interval category corresponding to the difference temperature, and attenuate the output power of the heating block based on the attenuation coefficient corresponding to the difference interval category.

[0050] The attenuation adjustment is performed according to the difference between the current temperature and the target temperature, so that the difference temperature between the current temperature of the incubator and the target temperature can be obtained by calculating the difference between the current temperature of the incubator and the target temperature set by the user. This difference temperature reflects the deviation between the current temperature of the incubator and the target temperature, and is an important basis for adjusting the output power of the heating block.

[0051] Thereafter, according to the size of the difference temperature, the current temperature can be divided into a corresponding difference category interval. Each difference interval corresponds to a specific attenuation coefficient, which is used to adjust the output power of the heating block. The attenuation coefficient is set between 0 and 1, and the output power of the heating block is attenuated according to the attenuation coefficient, so that the temperature of the incubator is stabilized and approaches the target temperature.

[0052] Through the above steps, the output power of the heating block can be accurately attenuated based on the difference temperature between the current temperature and the target temperature, thereby realizing the stable and accurate control of the temperature of the incubator. It can effectively avoid the temperature of the incubator exceeding the target temperature, prevent the corresponding additional operation and resource waste, and be beneficial to provide a safer and more comfortable treatment and care environment for the newborn.

[0053] Optionally, the difference interval categories include at least a first difference interval and a second difference interval, the first difference interval corresponding to a first attenuation coefficient greater than a second attenuation coefficient corresponding to the second difference interval.

[0054] Based on the foregoing steps, the present application can provide different attenuation coefficients in different difference interval categories to provide corresponding attenuation adjustment. The difference interval categories include at least two difference interval categories, i.e., a first difference interval and a second difference interval, and can also include three, four, five or more subdivided difference interval categories. Different attenuation coefficients are provided in different difference intervals. The attenuation coefficients can be set according to the change characteristics when the current temperature is close to the target temperature. For example, more attenuation can be provided by the attenuation coefficient in the difference interval closer to the target temperature. The attenuation coefficient can be similar to a normal distribution function to provide more attenuation in the relatively far and relatively near intervals and less attenuation in the middle interval. The attenuation coefficient can also be customized according to different treatment or care tasks, so as to configure different attenuation coefficients for different difference intervals and achieve different attenuation effects.

[0055] Preferably, the first difference interval is between 0.5℃ and 2℃, the first attenuation coefficient is 0.8, the second difference interval is 0 to 0.5℃, and the second attenuation coefficient is 0.3.

[0056] In the incubator of the present application, the adjustment is in a high humidity condition, and the temperature adjustment is used to provide a temperature environment for corresponding treatment or care. Therefore, the difference interval setting and attenuation coefficient selection should be based on actual conditions and specific needs. Here, the first difference interval is between 0.5℃ and 2℃, the first attenuation coefficient is 0.8, the second difference interval is 0 to 0.5℃, and the second attenuation coefficient is 0.3. The configuration of the difference interval and the attenuation coefficient can achieve better temperature control, and the required coefficient is less, which is convenient for quick configuration and deployment. The preferred scheme is used as an example. The setting means that when the difference between the current temperature of the incubator and the target temperature is between 0.5℃ and 2℃, the output power of the heating block is attenuated to 80% of the original, and when the difference is between 0 and 0.5℃, the output power of the heating block is attenuated to 30% of the original. Such a setting can ensure that the temperature of the incubator gradually flattens when it approaches the target temperature, avoiding sudden temperature rise or fall that may cause discomfort to the baby.

[0057] It should be noted that the above difference interval and attenuation coefficient are only exemplary and not fixed. In actual application, the difference interval and attenuation coefficient can be adjusted according to the specific model of the incubator, the use environment and the user demand, etc., to achieve better temperature control effect. In addition, in order to achieve more accurate temperature control, more environmental parameters such as humidity and air flow in the incubator can be considered to comprehensively adjust the output power of the heating block. At the same time, modern control theory and technology such as fuzzy control and neural network can be used to make the temperature control of the incubator more intelligent and adaptive to adapt to various complex and variable environments and use scenarios.

[0058] Step 60: When the target humidity is in the low humidity interval, the output power of the heating block is adjusted based on the temperature control PID algorithm, and when the current humidity is higher than the target humidity, the power output of the humidifying block is stopped.

[0059] When the target humidity is in the low humidity interval, the current humidity of the incubator will approach and maintain in the low humidity interval. In this interval, the heat generated by the humidifying block is not enough to significantly increase the overall temperature of the incubator body, and the temperature control PID algorithm has certain adaptability, which can effectively regulate the temperature of the incubator body. The temperature control PID algorithm is a PID algorithm applied to temperature control scenarios. The algorithm measures the error between the current temperature and the target temperature, and adjusts the output power of the heating block according to the size of the error, so as to realize accurate control of the temperature in the incubator. Specifically, the algorithm adjusts the output power according to the size of the error through proportional control, adjusts the output power gradually through the accumulated error through integral control, and adjusts the output power according to the rate of change of the error through differential control. Through the PID algorithm, the temperature change characteristics can be well adjusted to realize stable, fast and accurate power output.

[0060] As for humidity, the output power of the humidifying block needs to be adjusted through corresponding control algorithm, such as humidity control PID algorithm similar to temperature control PID algorithm, fuzzy control algorithm or neural network based predictive control, etc. When the current humidity of the incubator is higher than the target humidity, the heat generated by the humidifying block will increase the temperature of the incubator. At this time, if the power output of the humidifying block continues, it may cause the temperature of the incubator to exceed the preset safety range. Therefore, when the current humidity is higher than the target humidity, the power output of the humidifying block should be stopped to avoid the risk of high temperature of the incubator. In this way, the temperature and humidity of the incubator can be controlled cooperatively, so that the incubator can ensure comfortable humidity while avoiding the risk of high temperature, providing a safer and more comfortable treatment and care environment for the baby.

[0061] Through the above steps, by controlling the temperature and humidity of the incubator in the low humidity range to meet the requirements of the target temperature and target humidity, the precise control of the heating block and the avoidance of the uncontrolled temperature caused by overheating of the humidifying block can be realized, the optimization of the infant treatment and nursing environment can be realized, the effective and reliable temperature control and humidity control in the environment of the low humidity range can be ensured, and the safety and comfort of the infant treatment and nursing environment can be ensured.
