Definitions

  • the present invention relates to a modular biophysical reactor, it falls within a field of the scientific research devices for experiments and tests and it is intended primarily for studying changes in properties of the biological materials in short or long-term cultivation under different physical conditions (temperature and pressure, various atmosphere composition, e.g. hypoxia, hyperoxia or carbon monoxide poisoning) and studies of the changes in the behaviour of the living organisms or small animals.
  • the device can be used to verify a functionality of the technical devices or their components (tests of the components such as sensors, devices, and HW) under different pressure conditions and with different composition of the internal atmosphere.
  • Overpressure or underpressure (decompression) vessels are used in a number of technical, medical or scientific fields. They are usually designed for specific purposes such as testing of the instrumentation under overpressure and underpressure conditions, for medical purposes (mainly hyperbaric oxygen therapy), for pilots or astronauts training in weightlessness or for training athletes, and often for training and decompression rescue of divers.
  • medical purposes mainly hyperbaric oxygen therapy
  • pilots or astronauts training in weightlessness or for training athletes and often for training and decompression rescue of divers.
  • a hyperbaric chamber is constructed in a form of the cylinder with pressure- adapted terminal, which may take the form of an entrance to such a chamber.
  • the size of the chamber depends on its use, large chambers for dozens of patients, special purpose chambers as in the case of US20090038618A1 intended for the treatment of large farm animals up to single chambers are known.
  • Various variants of small or single-person chambers for training, therapy or testing were most often patented.
  • a decompression chamber for divers is known from DE3732167.
  • Another example is US5327904A describing a single-person chamber for a seated patient.
  • the body of the chamber can be made of the metal or flexible materials depending on the required internal overpressure and it is assembled as one unit.
  • An example of inflatable chamber is described in US20080006272A1, where the chamber is made of a flexible material and is reinforced with strips which also serve as a structural support.
  • a solution describing modular interior of the overpressure chamber is known from US6347628.
  • the modularity lies in an internal airtight and pressure-resistant removable partition system, which allows the chamber to function as a single-person and, if necessary, a multi-person chamber can be created by removing this partition system.
  • the external dimensions remain unchanged.
  • a fixed internal volume of the chamber is generally a major disadvantage of the known solutions.
  • Another common disadvantage of the known solutions is their construction for a specific purpose with a number of technical and technological applications, which prevents their universal use in other experimental or test workplaces or adaptation of the chamber for another purpose.
  • the disadvantage is the high acquisition costs and the complexity of the technical background and operator training.
  • Other known solutions are mostly devoted to a construction of the individual functional parts of the pressure chambers, e.g. CN200953821Y describes a method of heating the interior of the pressure vessel by means of a heating spiral.
  • CZ20118U1 a hypobaric and hyperbaric chamber is designed in a form of the non-metallic cylinder hermetically sealable on both sides, which is connected to a pump and a compressor and is connected to a control unit.
  • This chamber is intended for experiments with small mammals examined by magnetic resonance imaging. It is generally a therapeutic pressure vessel in which high pressures and a large temperature range cannot be achieved and the temperature inside the chamber cannot be regulated.
  • due to the non-metallic material used it is not chemically and mechanically resistant, so that various aggressive gas mixtures and various types of interior exposure cannot be used in the experiments.
  • a solution according to CZ305989B6 is known, disclosing a mobile hyperbaric mini-chamber, consisting of the container, the shell of which is adapted for hermetic closure by a lid using a locking mechanism, the chamber is equipped with sealable bushings to enable a connection with the internal space and provided with windows for monitoring the internal spaces.
  • the modular biophysical reactor according to the present invention is a special pressure vessel which falls into the field of experimental and testing scientific research devices. It is intended primarily for a study of the changes in the properties of the biological (cells, tissues, animal models) or other materials during short-term or long-term cultivation in various physical conditions and various atmospheric compositions (e.g. induction of hypoxia or hyperoxia), temperature and ambient pressure. It can also be used to study changes in the behaviour of the living organisms or small animals.
  • the invention can also be used to verify the functionality of technical devices or their components (testing of components such as sensors, devices, etc.) under various pressure conditions and with various compositions of the internal atmosphere. Its use is therefore partly similar to that of the hyperbaric chamber.
  • An essential feature of the invention is the construction of the reactor vessel from modules (parts or segments), while maintaining a hermetic tightness, which is a significant difference compared to conventional designs of closed vessels from one piece of material. According to the prior art search, such a concept has not yet been used.
  • the advantage of the modular design is the effective change or adaptation of the structure or internal volume of the reactor by simply replacing, adding or removing another part. In the event of a fault or a change request, only the part is replaced and it is not necessary to manufacture the entire vessel again.
  • the modular concept has another undeniable advantage and that is the reduced complexity of transport. In the case of large closed vessels of the hyperbaric chamber type, it is often necessary to make complicated construction modifications or to install the equipment before facility construction. In contrast, individual modules can be transported separately and assembled only at the final destination.
  • the modules are essentially hollow cylinders (chamber ring) with flanges for a firm mechanical connection using connecting means (e.g. rivets or bolts, preferably bolts) which ensure a firm mechanical connection of the modules and their mutual hermetical sealing.

  • a central module forms the main internal space of the reactor and can advantageously also be used for thermoregulation of the interior space of the reactor.
  • a method of interior temperature regulation can be chosen according to requirements, conditions, material used, etc.

  • the central module has an outer wall that is smooth or it is provided with surfaces for thermoelectric cells or with a channel for circulation of the tempering liquid.
  • An entry module with a hermetically sealable door serves to enter the internal space of the reactor according to the invention.

  • a construction of the door can be chosen according to the purpose of use, for example it can advantageously be provided with a toothed door fixation (the construction is known to a person skilled in the art). Then the door comprises its own toothed lid and a ring with teeth. Other mechanisms known to those skilled in the art can be selected for the door mechanism.

  • materials enabling the creation of highly smooth surfaces can be used.
  • the modular concept also allows the creation of a device from two (or more) different construction materials, such as metal and transparent plastic.
