    The control signal for regulating the intensity of the thermal radiation directed toward the infant is the temperature of the measurement probe in the form of an absolutely black or grey body, which is situated in the space to be heated by thermal radiation or in another space which is closely and continually connected with the latter. Said probe measures the quantity of thermal energy used for heating, released into the environment by the infant, removed from the environment by thermal radiation, and furthermore dissipated by heat transfer into the ambient air. The arrangement described comprises a heating radiator (1) serving to heat the infant and connected to the regulating unit (4), a reclining surface (2) or a bed (7) serving to receive said infant, or a heating radiator (1) and a boost radiator (11) in close association with the latter; in the thermal radiation space of one of the above-mentioned elements is arranged a measurement probe (3) provided with a temperature sensor (8), which sends out the control signal for the regulating unit (4) that controls the intensity of the thermal radiation; also provided is a support frame (5) or a base (6) for grouping all of the said elements into a single unit.

    ABOUT
    The invention relates to medical technology.
    The purpose of the invention is to increase the efficiency of controlling the intensity of thermal radiation.
    Figure 1 shows the device, a general view; figure 2 - measuring probe, longitudinal section; on fig.Z - the same, cross section; 4 - heat radiator, section.
    The device for heating infants contains a heat emitter 1 supporting the infant’s horizontal platform 2, a measuring probe 3 located in the heat radiation field, and a heat radiation intensity control unit 4 mounted on a common tripod 5. The executive body of the control unit 4 is a heat emitter 1, the control signal comes from the measuring probe 3. Inside the measuring probe provided with a partially or fully matted black coating (this is achieved when An approach to an absolutely black body) is a temperature sensor 6, which measures the temperature of the probe 3, which is a result of the influence of the surrounding space.
    The probe 3 may contain temperature sensors in any quantity. The limit is set by the geometrical arrangement or size of the heated object. Rotated to the heat emitter 1, the surface must be large enough to be able to measure the characteristics of the entire thermal radiation field, but at the same time, especially when the probe 3 is located between the emitter 1 and the object to be heated, when the thermal radiation is parallel or the diverging beam, the probe must be sufficiently mady to shield only a negligible part of the heated object.
    Heat emitter 1 contains heating rods 7, located in the focus of a double, made for this purpose in the form of a parabolic mirror of the screen 8.
    In order to determine the characteristic average value of the non-uniform thermal radiation field of the thermal radiator 1 or in the interests of more reliable operation, the device may contain several measuring probes 3 connected to the control unit 4, or several thermal emitters 1, measuring probes 3 and the adjusting blocks 4 - their maximum amount
    coincides with the number of thermal emitters 1, and each control unit 4 has at least one measuring probe 3 and one thermal emitter 1.
    The design of the measuring probe 3 in its properties may not be close to an absolutely black body, but in this wavelength range it has the properties of a gray body.
    The operation of the device is based on the fact that when under these conditions there are two bodies in the heat radiation field, which have known heat transfer and heat absorption coefficients at a given geometrical arrangement, there is a strict relationship between the temperatures of the bodies, i.e. that by measuring the temperature of one body it can be concluded that the temperature of the other body.
    A signal that characterizes the temperature of one or more measuring probes 3 located in a heat radiation field serving to heat infants and made for this purpose as an absolutely black or gray body can be used as a control signal to control the heat radiation intensity. The temperature of the measuring probe 3 is formed precisely depending on the thermal energy that is absorbed from the surrounding space and the thermal radiation field of the thermal radiator 1 and is released due to thermal radiation and heat transfer to still or moving air, as well as the temperature of the infant, who is under the same external conditions and is located in the same thermal radiation field. The skin of an infant precisely in the 1.5–13 mm wavelength range taken into account behaves like a completely black body, so that with this geometrical arrangement, the temperature of the probe can be used to control the intensity of heat radiation that warms the infant.
