Abstract

The present invention is related to a cryogenic chamber (1), in particular an open cryogenic chamber, containing a thermally insulated treatment part (2), a cooling system including a cooling fluid tank (3) containing the cooling fluid and a pipeline distributing the cooling medium, an exhaust fan (8) as well as a control-measurement system characterised in that the cooling system is equipped with a pipe-type or a pipe/lamelle-type heat exchanger (5) with inlet and outlet of the cooling medium, which is provided, along the entire length of the pipe or along a part thereof, with openings (6), in the form of slits and/or holes and/or nozzles.

Description

Cryogenic chamber
The present invention is related to a cryogenic chamber intended, in particular, for cryogenic treatments.
Cryochambers used in low-temperature therapy using liquid nitrogen are known in prior art. Polish patent Pat.209002 discloses a cryogenic chamber containing a chamber with thermally insulated walls, comprised of the treatment chamber, an adaptation chamber and a control-measurement system characterised in that it has the form of a hollow, whereas the shape of the cryogenic chamber is divided into two functional parts separated with thermally insulated walls, whereby the first, upper part comprises an adaptation vestibule with a transport path in the form of stairs leading to the hollow, and the second part comprises the treatment chamber with an entrance opening located at the side of the transport path.
American patent application US2013/0025302A1 discloses a cryosauna used for recreational purposes, containing a source of liquid nitrogen, a device for mixture preparation and a patient zone. The device contains interconnected parts: a thermally insulated evaporator and a mixer. The evaporator is connected via a valve with the source of liquid nitrogen, the mixer is connected via an open fan to the ambient air and to the patient zone. The patient zone does not have a ceiling, it is provided with walls, a floor and a regulated platform adapted to the patient. The cryosauna also contains a return, side duct connected to the patient zone, whilst the evaporator is equipped with a three-way inlet valve, the first and the second inlet duct is connected with the patient zone with the inlet of the outlet valve, and a fan channel located at the outlet of the outlet valve.
The aim of the invention is to provide a cryogenic chamber for cryotherapeutic treatments with an increased cooling efficiency to the temperature ensuring safe performance of the treatment.
The nature of invention is the cryogenic chamber, particular an open cryogenic chamber containing thermally insulated treatment part, a cooling system including a cooling fluid tank containing the cooling fluid and a pipeline distributing the cooling medium, an exhaust fan as well as a control-measurement system characterised in that the cooling system is equipped with a pipe-type or a pipe/lamelle-type heat exchanger with inlet and outlet of the cooling medium, which is provided, along the entire length of the pipe or along a part thereof, with openings, in the form of slits and/or holes and/or nozzles.
Preferably, openings are located uniformly on the surface of the heat exchanger pipes.
Preferably, the heat exchanger is located within the treatment part. Preferably, distributing fans are located between the treatment part and the cooling system.
Preferably, liquid nitrogen is the cooling medium.
The aim of the invention was achieved by using a heat exchanged with openings in the cryochamber, through which evaporated, pressurised cooling medium leaves the heat exchanged and enters the cryogenic chamber, thus additionally accelerating temperature decrease inside the cryogenic chamber, thus also limiting the amount of the cooling medium required in order to achieve the desired temperature.
Placement of the heat exchanger in the therapeutic part, with a protective wall separating it from the patient, forced the released cooling medium to venture into the lower section of the treatment part, thus additionally accelerating temperature decrease inside the therapeutic part by pushing the warmer air upwards and outside the cryogenic chamber.
Use of fans between the treatment part and the cooling system forces an air flow inside the cryogenic chamber and accelerates temperature decrease inside the chamber.
The invention has been presented in preferred embodiments in the drawing, in which the following figures present as follows:
fig. 1 is a cross-section of the cryogenic chamber according to the invention, fig. 2 is a diagram of the cooling system of the cryogenic chamber according to the invention fig. 3 is the front view of the heat exchanged of the cryogenic chamber according to the invention.
Fig. 1 presents a cross-section of the cryogenic chamber 1 according to the invention. The cryogenic chamber 1 consists of the treatment part 2, the cooling system containing tank 3 with the cooling medium. Pressure inside the tank 3 causes the liquid cooling medium to be delivered via pipeline 4 to the heat exchanger 5, where it evaporates. Evaporation of the cooling medium to the gaseous phase results in pressure increase inside the heat exchanger 5, enforcing gas flow and its release through openings 6 inside the heat exchanger 5, into the interior of the cryogenic chamber. After the therapeutic session, the cooled air including the gaseous cooling medium is removed from the chamber via ventilation ducts 7 provided with an exhaust fan 8.
In a preferred embodiment of the present invention, the heat exchanger 5 is located inside the treatment part 2 and separated from the patient with a protective wall 9, which additionally forces the released, gaseous cooling medium to venture into the bottom section of the treatment part 2.
Fig. 2 presents a diagram of the cooling system of the cryogenic chamber according to the invention. The cooling system of the cryogenic chamber 1 consists of a cooling medium tank, connected to the pipeline 4 providing the cooling medium to the heat exchanger 5, preferably equipped with distributing fans 10.
Fig. 3 presents front view of the heat exchanger 5 of the cryogenic chamber according to the invention, in which, before the outlet 5b of the cooling medium, on the surface of the pipe 5c, openings 6 are located, enabling the cooling medium - introduced as a liquid via the inlet 5a, is released in gaseous form as a result of increased pressure generated during its evaporation.
Because of the mentioned reasons, presented embodiments of the invention should not be interpreted as by any means exhaustive or limiting the present invention, the nature of which is characterised in the appended claims.
