Description

CZ 305989 B6

Mobile hyperbaric minicom

Technical field

The invention relates to the field of experimental and testing equipment development and relates to the construction of mobile hyperbaric mini-chambers designed in particular to verify the functionality of devices or their components and to monitor changes in the properties of biological or other materials, respectively. changes in the behavior of living organisms or small animals at elevated pressure of the working medium, such as air, gas or mixtures thereof.

BACKGROUND OF THE INVENTION In many technical, medical, or other fields, pressurized or vacuum chambers are used, most of which are designed for specific purposes, such as medical health, for training airmen or astronauts in weightlessness or for training athletes, rescuing divers. For example, a solution for the diving decompression chamber according to DE 3 732 167 or the training chamber for athletes and divers described in CZ 3077 Ul is known. Another known solution is, for example, the chamber described in CA 2 845 398, which, although relatively small, is portable by several persons but is intended for therapeutic purposes only. The modified neonatal treatment pressure device is described in CN 2 382 403 Y, but only the optimal design of the entrance door is solved. A common disadvantage of these known solutions is their construction for a specific purpose with a number of technical and technological applications, which make their universal use even in other experimental or testing workplaces impossible. In addition to their large dimensions, their further disadvantage is the high purchase costs and the complexity of the technical facilities and the training of operators.

Also known are pressurized or vacuum chambers for use with various test and analytical methods, including in the medical and biology fields, including, for example, U.S. Pat. No. 6,247,472, which discloses a method of utilizing heat generated in a hyperbaric chamber for thermodynamic work , which is used to further increase the chamber pressure. Other known solutions are mostly devoted to the construction of individual functional nodes, eg CN 200953821 Y describes a method of heating the interior of a pressure vessel by means of a heating coil. JPH 04184138 then describes a pressure device with a small internal space for high pressure and temperature experiments. However, its construction does not allow inserting larger objects and controlling the internal climate of the chamber. CN 202251235 solves the location of the LED source in a pressure vessel by means of a special pressure resistant capsule, which increases the cost of the device and results in a reduction in the sample loading space. Finally, the solution described in CZ 20118 U1 is known, where the hypobaric and hyperbaric chamber is designed in the form of a hermetically sealable non-metallic cylinder which is connected to a vacuum pump and a compressor and is connected to the control unit. This chamber is intended for experiments with small mammals examined by magnetic resonance. It is generally a therapeutic pressure vessel in which high pressures, high temperature ranges and no temperature control within the chamber can be achieved. Moreover, it is not chemically and mechanically resistant due to the non-metallic material used, so that various aggressive gas mixtures and different types of interior exposure can not be used in experiments.

It is an object of the present invention to provide a new mobile hyperbaric mini-chamber that utilizes the design, dimensions, and operating parameters to address the drawbacks of known solutions and to be seamlessly applicable to a wide range of experimental and test areas, particularly in biomedical and biochemical experiments. testing the functionality of small devices and equipment designed to operate at elevated pressure, such as equipment for divers, small devices designed to operate in large hyperbaric chambers such as ECG, oximeters, etc. - 1 - CZ 305989 B6

The present invention achieves a new and higher effect in that its concept allows the construction of a small-sized chamber, which is advantageous by its operating parameters for use in a wide range of biochemical and biomedical and industrial experiments as required to create specific physical parameters of the internal pressure environment. The mini-chamber, including its accessories, is easy to move when its tested basic cylindrical design has a working space volume of 5 liters, the internal working surface diameter is 20 cm, the maximum operating pressure is 10 bar, the maximum flow rate of pressurized working media, preferably gases, is up to 50 1 / min, working medium temperance rate through heat exchanger passage up to 2 ° C / s, working medium mixing speed up to 5 liters / min, indoor ambient temperature range -5 to 60 ° C and possible indoor temperature change rate up to 5 ° C / min. A great advantage of the presented solution is the simple construction of a mini-chamber, which is reflected in relatively small acquisition costs, which makes it accessible to a wide research and development area, especially at universities and research institutes of various focus.
