Abstract: A humidifier for a respiratory apparatus includes a first cover, a second cover engaged with the first cover and a partition plate. The first cover defines an air inlet. The second cover defines a chamber configured to contain at least some amount of water. A heater is configured to heat the water to generate humidified air in the chamber. The partition plate is partly sandwiched between the first cover and the second cover. The partition plate defines an air outlet. Air input via the air inlet is humidified by being mixed with the humidified air and thereafter ejected through the air outlet. The air entering via the air inlet is divided by the partition plate into a plurality of flows having different flow velocities, thereby form a plurality of flow paths.

Abstract: A retractable USB connector includes an outer housing case, an inner housing case, and a positioning assembly. The outer housing case has an opening. The inner housing case includes a USB connector disposed at a first end of the inner housing case, a press portion disposed at a second end of the inner housing case, and the inner housing case disposed in the outer housing case. The positioning assembly is disposed between the outer housing case and the inner housing case. The positioning assembly includes a swinging member defining a positioning sliding-track and a guiding column, disposed in the positioning sliding-track. When the guiding column is located at a positioning area of the positioning sliding-track, the positioning assembly fixes the relative position of the outer housing case with respect to the inner housing case, and the USB connector is protruded from the opening of the outer housing case.

Abstract: The disclosure provides a gas flow detector comprising a conduit, a first and a second pressure gauges. The conduit includes a flexible pipe, a first and a second connecting pipes. The flexible pipe has a contraction portion, a throat and an expanding portion. Further, the throat is sandwiched between the contraction portion and the expanding portion, and the inner diameter of the throat is smaller than that of the contraction portion and the expanding portion. The first and the second pressure gauges are configured to respectively detect the gas pressure of the first connecting pipe and the throat, and the gas flow rates of the first connecting pipe and the throat is calculated from the reading of the difference of the gas pressures. A positive airway pressure apparatus (PAPA) containing the gas flow detector is also disclosed herein.

Abstract: A water chamber for a respiratory therapy apparatus has a base casing, a cover casing and a partition. The partition makes the air flows downward, turns around and then goes up to prolong the route and the time of the air passing through the water chamber. Therefore, the air can be saturated with moisture sufficiently to increase the air humidity. When the air is passing through the water chamber, the air is divided into two parts to each respectively enter a first tube and a second tube. The audio frequencies caused by the two parts of the air are changed due to a change of a cross sectional area. When the two parts of the air converge, the audio frequency is changed again. The partition makes the air in different portions of the water chamber have different audio frequencies, thereby reducing the resonance to eliminate noise.
