< radiation mechanism >
Neonatal hyperbilirubinemia (jaundice) is one of the common diseases in the neonatal period, with a high incidence, especially in asian races, with visible jaundice appearing in about 60% of term and 80% of premature infants in the 1 st week after birth. Bilirubinemia-induced bilirubin encephalopathy seriously threatens the life and health of newborn infants, is one of the main reasons for hearing impairment, abnormal vision and intelligent lagging of infants, and even dies the serious patients. Various methods for treating neonatal jaundice are available, and blue light phototherapy (phototherapy) is widely applied due to the characteristics of non-invasiveness, effectiveness, simplicity, economy and the like.
Bilirubin can absorb light waves and convert unbound bilirubin into water-soluble isomers under the action of light, namely, bilirubin IxaZ type is converted into IxaE type and bilirubin, and the bilirubin is excreted into the intestinal cavity through bile or is discharged from urine. By applying the principle, the blue light LED light source is adopted, and the 400-550 nm visible light emitted by the light source is irradiated on the skin surface of a patient, so that bilirubin is not combined in epidermal blood to generate the biochemical reaction, the serum bilirubin concentration is reduced, and the aim of treating jaundice is fulfilled.
Referring to fig. 8 and 9, the radiation mechanism includes a fixing frame 81, a blue light lamp 82 and a protective cover 83, the fixing frame 81 fixes the radiation mechanism on the upper portion of the thermal insulation box, the blue light lamp 82 is fixed on the fixing frame 81 to irradiate the interior of the thermal insulation box, the protective cover 83 is disposed around the blue light lamp 82 to protect the blue light lamp 82, and external factors (people or other objects) are prevented from touching the blue light lamp 82.
The fixing frame 81 is fixed in the fixing cover 141, so that the fixing frame can be lifted along with the fixing cover 141, and the radiation mechanism can be maintained conveniently (the radiation mechanism can be maintained by taking down the clamped extension cover 142).
Therefore, when the infant suffers from jaundice and needs to be treated, the infant can be irradiated and treated only by turning on the power switch (the infant does not need to be transferred to other treatment equipment for treatment), and the infant radiation treatment device is very convenient to use.
The radiation mechanism also includes a reflector plate 84. The reflector 84 is fixed on the fixing frame 81, the blue-light lamp 82 passes through the reflector 84 and is fixed on the fixing frame 81, and the blue-light lamp 82 is located at the focus of the reflector 84 close to the fixing frame 81.
The straight line of the two focal points of the reflective plate 84 forms an inclined angle with the plane of the fixing frame 81, and the inclined angle can be an acute angle of 45 degrees in a manner of 'point-shaped' side installation.
When the blue light lamp 82 emits blue light, a portion of the light can be focused by the reflector 84 to another focal point of the reflector 84 away from the fixing frame 81, and the focal point is outwardly diverged.
Thus, the radiation mechanism is designed with the reflection plate 84, so that the blue light lamp 82 is positioned at the focus of the reflection plate 84 close to the fixed frame 81, thereby enabling the light in the radiation mechanism to perform 'point-like' radiation, and having the characteristic of uniform heat distribution; the light of the blue light lamp 82 is fully utilized, so that the utilization efficiency is high and the treatment effect is good; especially, the space occupation of the point-like radiation design mode is small, the adjustability of the optical radiation is greatly increased, the application of the radiation mechanism is greatly widened, and meanwhile, the design of the protective cover 83 has extremely high use safety performance and application convenience.
The blue light lamp 82 can be replaced by an incandescent lamp, an LED lamp or other lamps which can be heated; thus, the heat insulation box body is conveniently heated.
Example 2
Although the infant incubator can heat and insulate the temperature inside the incubator body, the ultimate achievable temperature limit value mainly depends on the outside temperature due to the limitation of materials or heating modes, that is, the temperature difference between the inside and the outside of the incubator body must be less than a certain temperature difference threshold, and the influence of heating and insulation on the inside of the incubator body on the infant is minimum under the condition that the temperature difference threshold is less than the temperature difference threshold; if the temperature difference is greater than the temperature difference threshold value, the temperature inside the incubator body may not reach the temperature to be maintained, and even if the temperature to be maintained can be reached, the heating lamp and the like can be irradiated or sealed for too long time, so that the health of the infant placed in the incubator body is damaged.
Therefore, it is essential to accurately detect the temperature outside the infant incubator in order to keep the infant incubator warm and greatly reduce the influence on the health of the infant.
However, the temperature outside the infant incubator and the temperature near the infant incubator are greatly different due to the problem of heating inside the incubator, and once the temperature sensor for detecting the temperature is too close to the heating point or the temperature sensor is damaged, a large error is brought to the detection of the temperature, so that the influence of the infant incubator on the health of the infant is increased.
Based on this problem, the present embodiment improves the technical solution on the basis of the above embodiment, and the present embodiment is different from the above embodiment in that a plurality of temperature sensors are arranged on the infant incubator, and the temperature sensors are connected to the controller 94; the controller 94 receives the temperature values transmitted from the plurality of temperature sensors, calculates the actual temperature value outside the infant incubator, and displays the calculated temperature value.
Therefore, the actual temperature value of the outside can be directly read through the display, so that the temperature of the heat preservation box is required to be kept.
The controller 94 may also determine whether the difference between the temperature in the thermal container and the actual temperature exceeds the temperature difference threshold, and send an alarm to the outside after the difference exceeds the temperature difference threshold. Thus, setting errors can be prevented, and damage to the health of the baby can be prevented.
Example 3
As mentioned above, the difference between the present embodiment and the infant incubator is that the calculation formula of the real temperature value is:
Figure BDA0001335731400000171
in the formula, Pi、QiDetermined by the following equation:
Pi＝δ(Li)
Figure BDA0001335731400000172
Qi＝δ(Mi)
Figure BDA0001335731400000173
Figure BDA0001335731400000174
wherein x is the real temperature value, i is the serial number of the temperature sensor, n is the total number of the temperature sensor, xiFor the temperature value measured by the ith temperature sensor,
Figure BDA0001335731400000175
The average value of the temperature values measured by the temperature sensor, M is the normal allowable deviation range, l is the allowable deviation range of the heating point, MiIs a normal judgment value L of the temperature value corresponding to the ith temperature sensoriA heating point judgment value Q of a temperature value corresponding to the ith temperature sensoriIs the normal coefficient value, P, of the temperature value corresponding to the ith temperature sensoriA heat generation point coefficient value, δ (M), of a temperature value corresponding to the ith temperature sensori)、δ(Li) Is a unit impulse function.
Wherein, δ (M)i)、δ(Li) Is a unit impulse function, which is defined as:
Figure BDA0001335731400000176
the basic idea is as follows: firstly, calculating the average value of the temperature values and the difference value between the temperature values and the average value, then dividing the difference value by the average value of a certain percentage (the percentage can be less than 100% or more than 100%) and then taking the difference value as a judgment value, converting the judgment value into coefficient values through a unit impulse function, finally, taking the two coefficient values as the coefficients of the temperature values, and then dividing the sum of the product of the coefficient values and the temperature values by the sum of the coefficient values to obtain a real temperature value, wherein the real temperature value is closest to the actual temperature value.
The beneficial effects are that: determining the deviation condition of the temperature value by calculating the average value of the temperature value and the difference value between the temperature value and the average value, dividing the deviation value by the average value with a certain percentage, and then rounding down to convert the difference value into a judgment value, wherein if the difference value is allowable, the judgment value is 0; if not, the judgment value is a positive integer larger than 0; by setting a normal allowable deviation range and a heating point allowable deviation range (the normal allowable deviation range is smaller than the heating point allowable deviation range, that is, if a temperature value is within the normal allowable deviation range, it is certainly within the heating point allowable deviation range, if a temperature value is within the heating point allowable deviation range, it is certainly within the normal allowable deviation range), the temperature sensors belonging to the normal deviation but not the fault and the temperature sensors belonging to the vicinity of the heating point but not the fault are distinguished to obtain respective judgment values; converting the judgment value into a coefficient value through a unit impulse function, and dividing the sum of the coefficient value multiplied by the temperature value by the sum of the coefficient value, so that the influence of the temperature value with the coefficient value of 0 (out of an allowable range) on the finally determined real temperature value can be eliminated; when the sum is calculated, the product of the normal coefficient value and the temperature value and the product of the heating point coefficient value and the temperature value are added, and the sum of the normal coefficient value and the heating point coefficient value is divided, so that the weight of the temperature value measured by the temperature sensor near the heating point is reduced, and the influence of the temperature value measured by the temperature sensor near the heating point on the real temperature value is weakened; meanwhile, the result can be directly obtained through a formula, and the formula is simple and convenient to calculate; and the judgment speed is improved, and the system resources are saved.
Here, the normal allowable deviation range means that although the temperature value deviates from the average value, the temperature value can be considered as being normally measured (merely due to mechanical error of the temperature sensor itself or the temperature of each part in the environment is not completely consistent), rather than the temperature sensor being damaged. The allowable deviation range of the heating point means that although the temperature value deviates from the average value, the temperature value can be considered to be normally measured in the vicinity of the heating point (except that the temperature of each part in the environment is not completely consistent due to the mechanical error of the temperature sensor itself, and the temperature in the vicinity of the heating point is higher than that of other parts), and the temperature sensor is not damaged.
Under normal conditions, the external temperature of the infant incubator comprises normal temperature and the temperature is close to a heating point; when the actual temperature is considered, the normal temperature is very close to, but not identical to, the actual temperature; the heating point temperature is higher than the actual temperature, but the heating point temperature still has influence on the actual temperature; the temperature measured after the temperature sensor is damaged is independent of the actual temperature.
The foregoing is merely a preferred embodiment of the invention, which is intended to be illustrative and not limiting. It will be appreciated by those skilled in the art that many variations, modifications, and equivalents may be made thereto without departing from the spirit and scope of the invention as defined in the claims.
