Definitions

  • Heat therapy device and method for heat therapy are Heat therapy device and method for heat therapy
  • the invention relates to a heat therapy device according to the preamble of claim 1. Furthermore, the present invention relates to a method for heat therapy according to the preamble of claim 28.
  • Heat therapy devices of the type mentioned are generally used in gynecological departments of hospitals for newborns.
  • the previously known heat therapy devices incubators have closed, air-conditioned cabins, in which a flap must first be opened to access the newborns. When removing a newborn from such a heat therapy device, care must always be taken not to injure the newborn.
  • Another disadvantage of the known incubators is the psychological effect that such booths have on the parents of the newborn.
  • the object of the present invention is therefore to provide a heat therapy device of the type mentioned at the outset, in which the disadvantages described above do not occur.
  • the characterizing features of claim 28 are provided to achieve the object.
  • the configuration according to the invention results in a so-called open therapy device.
  • the microclimate prevailing in the incubator the parameters of which are defined, for example, in DIN EN 60601-2-19, is stabilized and limited by air currents.
  • the desired microclimate forms within the space delimited by the upward directed air jets.
  • the embodiment according to the invention has the essential advantage that access to an infant on the lying surface is quick and easy. subject can be done. Furthermore, it is possible for the parents of the newborn to be able to look at and touch them directly without having to open a flap first, as is the case with the heat therapy devices known from the prior art.
  • the invention has no negative psychological effect on the parents of the newborn, as occurs in closed incubators.
  • a flow-stabilized microclimate above the lying surface can already be achieved by only providing a three-sided air flow with a simultaneous suction ring above the head side. No air is thus supplied in the area of the head sides, which ultimately reduces the energy requirement of the heat therapy device according to the invention, since less supply air is required.
  • the lack of air supply in the area of the head also means that drafts cannot occur in this area.
  • it goes without saying that, in principle, it is also possible to provide an air duct on the top side if this is considered necessary if necessary, although the three-sided flow duct is preferred.
  • an end wall is provided on the head side, which is preferably at least essentially over the length of the Head side extends.
  • the end wall thus initially has a partitioning effect and can also perform a holding function for the suction device, so that the suction device is fastened to the end wall and can at least partially overhang the lying surface.
  • the side guides extend at least substantially over the length of the long side.
  • the suction device should extend at least essentially over the head side in order to ensure the largest possible detection area.
  • the suction device In order to restrict access to the lying surface by the suction device or the base body of the suction device as little as possible, it is advisable for the suction device to overhang the lying surface from the head side up to a maximum of 2/3 of the length of the lying surface. It goes without saying that a cantilever should be provided in accordance with this feature and any value up to a maximum of 2/3 of the length of the lying surface is possible without the need for an explicit listing of discrete values.
  • the outflow direction of the air supplied from the side depends on the climatic conditions of the ambient air and the microclimate of the heat therapy device to be set.
  • the angle should be larger as the density differences between the outflowing air and the surrounding air increase. In extreme cases, this can even be 90 °.
  • This can lead to different embodiments, because e.g. For example, the environment in European hospitals is air-conditioned in summer to approximately 26 ° C, while in the United States 20 ° C room temperature is maintained. Basically, however, it is advisable that the flow directions of the side feeds and the foot feed have an angle between 10 ° and 60 ° with the vertical. These inclined supply air flows create a kind of "flow tent" under which the desired microclimate is formed.
  • This "flow tent" can be very small because it is intended for infants. Accordingly, it makes sense to arrange the suction device at a very small distance above the lying surface, preferably at a distance that is less than the width of the lying surface.
  • This arrangement has the additional advantage that only relatively short air curtains have to be formed, which is simple and inexpensive and, moreover, is possible with low flow velocities. In any case, flow velocities of the supplied air of less than 15 cm / s, preferably less than 8 to 10 cm / s, can be maintained, with any flow speed within the specified interval being possible here, too, without requiring an explicit mention.

  • the suction device is adjustable in height and / or that the suction device is preferably adjustable about two axes of rotation arranged perpendicular to each other.
  • the aforementioned oblique outflow direction can in principle also be realized in that the side feeds and / or the foot feeds are arranged inclined in a frame surrounding the lying surface in the direction of the lying surface.
  • the inclined frame with the feeds is then not only of fluidic importance, but also serves as protection for the infant on the lying surface against falling down.
  • protective walls can be provided on the side feeds and on the foot feed, regardless of whether the individual feeds are arranged inclined or not.
  • the protective walls should be releasably connectable to the respective feed, preferably snap into corresponding slots.
  • the protective walls can be arranged at an angle to the vertical, so that they can have a flow-guiding function.
  • a flap or guide flap can be provided on the suction device. It is advantageous if the flap is pivotally mounted. For example, it can be placed in a lower position, in which the flap has a flow-guiding effect, or in an upper position, in which unimpeded access to the lying surface is guaranteed.
