An outlet of the heat supply network primary side water return pipeline communicates with a water side inlet of the fused salt-water heat exchanger, a water side outlet of the fused salt-water heat exchanger communicates with the heat supply network primary side water inlet pipeline, and heat supply can be guaranteed through the system.

A method of treating sleep disorder breathing in a patient, the method comprising in a first step providing a set of oral appliances comprising a first and at least a second oral appliance (30). Each of the first and at least second oral appliances comprises a generally U shaped appliance body including an inner wall (34), an outer wall (36), and a web (38) interconnecting the inner wall and the outer wall. The web has a front section and two arms with trailing ends. The web comprises at least one breathing hole (80) so as to define a total cross sectional area for breathing and the total cross sectional area for breathing of the first oral appliance is larger than the total cross sectional area for breathing of the second oral appliance. In a second step, a patient wears the first oral appliance in a first treatment stage whilst sleeping for a first period of time and in a third step the patient wears the second oral appliance in a second treatment stage whilst sleeping for a second period of time.

The utility model belongs to the field of octagonal hatching box machines, and particularly relates to a ventilation structure of an octagonal hatching box machine, which comprises a case, an air inlet pipeline is fixedly arranged in the middle of the case, air outlets are arranged on two sides of the upper end of the case, a water cooler is fixedly arranged in the middle of the inner side of the case, and a ventilation fan is arranged on the water cooler. A mounting frame is fixedly mounted in the case, a bearing seat is fixedly mounted at the upper end of the mounting frame, and a bearing is fixedly mounted in the bearing seat. The two air inlet pipelines are arranged in the middle of the machine body for air inlet, the two sides of the machine body for air outlet, and the bottoms of the air inlet pipelines extend to the positions close to the centers of the fan blades, so that the negative pressure of the air inlet pipelines is greatly increased, the air speed in the air inlet pipelines is greatly increased, and the uniformity of airflow in the equipment is optimized; and through uniform distribution of the water cooler structure from top to bottom, the water cooling effect is greatly improved, and the concentration of carbon dioxide in the machine body can be reduced.

The invention discloses an intensive care unit disinfection and ventilation fresh air system, and particularly relates to the technical field of hospital ventilation equipment.The intensive care unit disinfection and ventilation fresh air system comprises a fresh air box, an air inlet pipe fixedly communicates with one side of the fresh air box, an air outlet pipe fixedly communicates with the portion, close to the bottom of the air inlet pipe, of one side of the fresh air box, and a first connecting pipeline fixedly communicates with the other side of the fresh air box; an exhaust fan is fixedly mounted at the bottom of the first connecting pipeline; a fresh air treatment box is arranged on one side of the fresh air box.
