Definitions

  • the invention relates to a device for generating a dry, cold air flow for the treatment of rheumatic diseases.
  • the invention relates to a device for local therapy.
  • the cold air flow for local therapy must be dry and be ice-free. Since the air is cooled to around -150 ° C, it is naturally dry, but it must be prevented that the frozen ice particles reach the surface of the body. This would lead to frostbite, at least in the form of micronecrosis.
  • the invention has for its object to provide a device for generating a dry, cold air flow for the treatment of rheumatic diseases, which does not have these disadvantages and is particularly ready for use with low refrigerant consumption and suitable for continuous operation.
  • a device for generating a dry, cold air flow for the treatment of rheumatic diseases with a connection for supplying a cryogenic liquefied gas, a blower for generating the air flow, and a device for heat exchange between the liquefied gas and air flow, which separate the frozen ones Moisture enabled, found in which, according to the invention, a cyclone separator serves as a device for heat exchange, the inlet line of which is connected to the outlet opening of the blower by a line in which the connection for supplying the liquefied gas ends and to the outlet opening of which a flexible hose is attached .
  • the basic idea of the invention is therefore to design a device in which the heat exchange between the cryogenic liquefied gas, that is to say usually nitrogen, and the air takes place directly.
  • the liquefied gas is sprayed into the inlet line of a cyclone separator.
  • the air cools down immediately, the moisture contained in it freezes out in the form of ice particles.
  • the heat exchange is continued in the cyclone separator and the ice is separated.
  • the separated moisture collects in the lower part of the cyclone separator, thaws there and is drained off as water from time to time, for example during breaks in operation.
  • the device shown in Fig.1 has inside it the facilities for generating the cold air flow, commissioning and monitoring is carried out by fittings and switches on the front 1 of the device.
  • a flexible insulated hose 2 leads out of the device and ends in a handpiece 3.
  • the device also has a connection opening 4 for supplying liquid nitrogen and a plug 5 for establishing an electrical connection.
  • the device also has a separate removable storage container 6 for liquid nitrogen.
  • This storage container 6 contains the actual nitrogen storage 7 in its interior. It also has a connection 8 through which liquid nitrogen can flow out of the nitrogen storage 7.
  • FIG 2 shows the device of Figure 1 in a schematic representation.
  • Liquid nitrogen is withdrawn from the nitrogen reservoir 7 by means of the pump 10.
  • the connection of the connection 8 and the connection opening 4 is represented by the quick coupling 11.
  • the air flow is generated by a fan 14, and the air is sucked in through the filter 15.
  • the outlet opening of the blower 14 is connected by a line 16 to the inlet opening of a cyclone separator 17.
  • the connection 8 ends in the line 16 from the nitrogen store 7.
  • the insulated hose 2 with the handpiece 3 is connected to the outlet connection 18 of the cyclone separator 17.
  • a valve 19 At the lower conical part of the cyclone separator 17 there is a valve 19 to which a waste water separator and Evaporator 20 is connected. There is a temperature measuring device 21 in the vicinity of the handpiece 3. Furthermore, an exhaust air fan 22 is located in close proximity to the device. An electrical connection (not shown) causes the exhaust air fan 22 to forcibly run as soon as the device is switched on. An electrical lock, also not shown, also ensures that the nitrogen supply through the solenoid valve 12 is interrupted if the exhaust fan 22 should not run, for example because of a technical defect. Also in close proximity to the device according to the invention is an oxygen warning device 23, which, however, has no functional conductive connection with the device according to the invention.
  • the dry, cold, nitrogen-enriched air leaves the cyclone separator 17 through its outlet connection 18, the insulated flexible hose 2 and the handpiece 3. It then goes directly to the part of the body to be treated.
  • the temperature of the air flow is controlled and regulated by the temperature measuring device 21.
  • the temperature control is extremely simple, since only the amount of nitrogen sprayed in needs to be varied.
  • the amount of air can also be easily varied by changing the speed of the fan 14.
  • the nitrogen-rich air is continuously extracted by the exhaust air fan 22. Should the oxygen content nevertheless fall below a permissible value, this is indicated optically and acoustically by the oxygen warning device 23.
  • the device according to the invention is a compact unit that can be installed in any room without external leads.
  • the reservoir 6 can be easily replaced at any time when the nitrogen in the nitrogen storage 7 is running low.
  • the liquid nitrogen can be stored in small quantities directly in the treatment room, the shortest possible routes are possible. All that is required is a connection for the electrical power supply.
  • the amounts of air and liquid nitrogen to be mixed can be set separately and independently.
  • the temperature of the cold air flow can be preselected and set over a wide temperature range as desired or required.
  • the device is ready for operation within a very short time.
  • the ice separation in the cyclone separator 17 is safe and reliably prevents ice particles from getting onto the patient's body surface, which could cause cold damage from micronecrosis.
