Description

The utility model (device) relates to medical equipment and can be used in healthcare (specifically, in the departments of physiotherapy, rehabilitation treatment) for therapeutic treatment of patients with the help of a gas treatment medium formed in closed volumes (bathtubs, cells, boxes).

Known devices for therapeutic (specifically, thermal) exposure of the patient’s body using portable dry-air baths or saunas (SU, invention No. 942754 class A61H 33/06; SU, invention No. 1101229 class A61H 33/06). In these devices, in order to ensure uniform temperature distribution throughout the chamber volume and eliminate the risk of burns to the patient with hot air coming directly from the heat source, it is proposed to heat the internal volume of the device due to the flow of hot air pumped through the gap between the two walls (shells) of the device. However, this method of heating and thermoregulation is too inertial, quite complicated and costly (the need to organize two separate circulation circuits, air and gas) if it is used during air-gas treatment procedures.

It is also known “Device for conducting carbon dioxide baths” (SU, invention No. 1710053 class A61H 33/06), consisting of a closed chamber with an opening for the patient’s head with a door (cover), seat and systems: automated temperature maintenance, carbon dioxide supply and moisture, as well as the exhaust system, located in a separate technological unit (control rack). Inside the box, a design is provided in the form of a guiding shield and a ventilation duct with the possibility of telescopic movement in the vertical direction (in order to compensate for the difference in the growth of patients). This design is designed to give the air-gas mixture a certain circulation mode, as well as blocking the exit of gas to the outside and its entry, as a result, into the respiratory tract of the patient and staff.

However, the device has a number of disadvantages inherent in this design:

- complexity and cumbersome due to the presence of two large-sized pieces of equipment, interconnected by a system of ducts and cables;

- increased energy consumption to compensate for losses in the duct during the transfer of thermal energy from the process unit to the treatment box;

- the complexity of "fitting" the hard guide plate and the ventilation duct for a particular patient, which is why the task of blocking the gas exit to the outside is not efficient enough and there are unproductive losses of time for "fitting" in preparation for the procedure.

Closest to this claimed utility model is “Device for conducting balneotherapy procedures” (specifically carbon dioxide and radon), consisting of a closed chamber with an opening for the patient’s head, with a door (cover), seat and systems: indication and automated maintenance of the parameters of the procedure, supply carbon dioxide, radon and moisture, as well as the exhaust system (RU, patent for invention No. 2066548 class A61H 33/06). A feature of this device is the presence inside the box, for example, under the seat, of a replaceable unit (block) for forming and supplying the treatment mixture, connected to the main structure of the box with a system of cables and ducts. The described device is adopted as a prototype.

However, the analogue (“Device for conducting carbon dioxide baths”) and the prototype have a number of common disadvantages:

- the problem of creating a gas medium inside the box that is homogeneous in composition and temperature is not solved due to the fact that the hot air-gas mixture entering the bulk box from the duct, firstly, immediately rises up as lighter, but, the second, as a rule, “swirls”, forming, especially in the corners of the box and behind obstacles (for example, the human body), the so-called “shadow” zones with parameters sometimes significantly different from the main volume;

- the presence in the volume of the gas mixture, due to the weight difference between cold and hot air, of a vertical temperature gradient, as a result of which the temperature at the box floor is usually several degrees lower than at the top;

- the danger of uncomfortable exposure to the patient with hot air coming into the box directly from the heat source, which requires the adoption of special protective measures in the form of screens, "bumpers", etc., further exacerbating the problem of the formation of "vortices" and "shadow" zones.

The noted drawbacks of analogues and prototype are eliminated by the claimed utility model, which is presented in the form of a closed box with a door, a hole for the patient’s head and an elastic gas-tight collar (neck seal), seat and systems: indication and automated maintenance of the parameters of the procedure, exhaust, gas supply (for example, carbon dioxide or radon) and moisture, moreover, the box is made with a double floor over the entire width of the box, corresponding to a rectangular niche for the gas mixture to exit from the inter-field space, located in the lower front of the box, with similar windows in the rear inner wall (behind the patient) and with an inclined front wall, and a heat source (for example, a fan heater) is located in the rear bottom of the box so that the heat flux from the source is directed primarily to interfloor space. To compensate for the difference in patient height, the seat and neck seal made of soft, gas-tight material have the possibility of variation (resizing) in height.

Thanks to the above design features:

- the gas mixture flows through the path: the fan heater — the gap between the floor and the raised floor (“interfloor” space — a rectangular niche for the gas mixture to exit from the interfloor space — the front inclined box wall — the patient-window body in the rear inner wall — the fan heater.

- fundamentally changing (relative to the traditional one used in analogues and prototype) the method of distribution of thermal energy inside the box so that the floor heating occurs immediately after the fan heater (when the flow temperature is maximum), and the flow exit (after passing through the interfloor space, i.e. after loss of a substantial part of energy) into the box volume occurred at a lower temperature, optimal from the point of view of safety, comfort and compliance with medical indications tvie then reduced to almost zero gradient adjustment Boxing temperature;

- the gas mixture flow over the entire volume of the box is formed in the form of a wide front ("curtain") quite uniform in composition and temperature without "vortices" and "shadow" zones.

The presence of these elements and solutions in the claimed device allows to eliminate the above disadvantages of analogues and prototype, to enhance the therapeutic effect by increasing the accuracy of maintaining the parameters of the procedure, to increase comfort and safety during the procedure, to reduce energy consumption by optimizing the heat flow distribution scheme.

The claimed utility model can be implemented, for example, in the form of a box 1 for receiving the procedure in a sitting position, and the patient’s head, thanks to the neck seal 2, is outside the action of the treatment medium,

The treatment medium is formed in the form of therapeutic gas supplied from outside (for example, carbon dioxide) and moisture (for example, in the form of steam supplied from a steam generator). Using a fan heater 3, the gas mixture is heated, mixed, and then sent to the gap (space) between floor 4 and raised floor 5, where it gives a significant part of the energy to the floor heating. Further, when the temperature is lowered to almost comfortable values, the gas mixture enters through a rectangular (almost the entire width of the box) niche 6 in the front lower part of the box to the inclined front wall 7, which directs the gas gas formed by composition and temperature, which is almost uniform throughout the volume mixture per patient. After passing the patient, the gas mixture through the windows in the rear inner wall 8 again falls on the fan blades (fan heater), etc. The seat 9 and cervical seal are made with the possibility of height adjustment depending on the height of the patient.

At the end of the procedure, the exhaust gas containing carbon dioxide residues, as well as a small amount of water condensate, is removed using an exhaust fan outside the premises, for example, to the street.
