20140166011 | NEBULIZER MOUTHPIECE FOR REDUCING DRUG LOSS - A method for reducing a loss of medication from a nebulizer includes the steps of entraining a liquid medication into a first flow of a pressurized gas into a nebulizer chamber and also entraining an additional amount of the liquid medication into a second flow of ambient air drawn into the nebulizer chamber through an opening when a patient inhales through the nebulizer chamber. When the patient exhales, a portion of the exhaled breath is directed into the outlet of the nebulizer chamber, thereby increasing a backpressure within the outlet and substantially stopping the second flow of ambient air into the nebulizer chamber, thereby decreasing the amount of medication lost to the ambient environment while the patient is not inhaling. | 06-19-2014 |
20140166012 | DEVICE FOR HUMIDIFYING BREATHING AIR FOR ARTIFICIAL RESPIRATION - A device for humidifying breathing air for artificial respiration of mammals, in particular human beings, includes at least one essentially closed container for receiving water, a first opening for letting in the non-humidified air and a second opening for letting out humidified air, and an inlet for supplying the water to the container. The inlet is located in the upper part of the container, which is adjoined by a tube essentially crossing through the container interior, and on the free end of the tube, a valve is disposed, which limits the level of the water supplied via the tube in such a way that the container bottom in the container interior is essentially covered with water. | 06-19-2014 |
20140261419 | WATER CHAMBER FOR A RESPIRATORY THERAPY APPARATUS AND A PARTITION OF THE WATER CHAMBER - 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. | 09-18-2014 |
20140261420 | PRESSURE CONTROL FOR RESPIRATORY HUMIDIFICATION APPARATUS - A humidifier assembly includes a water supply reservoir; and a vessel defining a water holding cavity configured to hold water at a water level, and having an inlet adjacent to the bottom thereof, a respiratory gas inlet, a respiratory gas outlet, a gas pressure equalization port, a water level control port, and a water level control pipe communicating with said water level control port and configured to extend below the water level in the cavity. Tubing directs water from the water supply container to said humidifier vessel. Tubing also extends between the water supply container and gas pressure equalization port and water level control port. A first one-way valve is disposed along a pressure equalization flow path between the reservoir and cavity, which path includes the gas pressure equalization port, with third tubing extending therefrom to an opposite end disposed under the water level in the water holding cavity. | 09-18-2014 |
