An intravascular port access device includes a first component having a chamber configured to attach reversibly to an intravenous line port. A second component reversibly attaches to the first component and contains a disinfecting agent and an applicator material. The second component is configured to be reversibly received over external surfaces of the intravenous line port. A method of cleansing an intravenous line port includes providing a port cleaning device having a first component with a chamber containing a first cleaning agent. A second component includes a second cleaning agent. A third component has a microbiocidal agent and is reversibly attached to the first component. The second component is removed from the device, the external surfaces of the port are contacted with the second cleaning agent, the first cleaning agent is ejected from the chamber into the port, and the third component is used to cap the port.

To provide a method of cleaning a film forming apparatus capable of uniformly removing a deposit containing tantalum nitride, titanium nitride, tantalum, or titanium adhering to a wall of a processing chamber of the film forming apparatus at a high etching rate without use of plasma. A method of cleaning a film forming apparatus for removing a deposit containing tantalum nitride, titanium nitride, tantalum, or titanium deposited on a processing chamber of the film forming apparatus after it is used for forming a thin film made of tantalum nitride, titanium nitride, tantalum, or titanium, the cleaning method comprising: a step of supplying process gas containing fluorine gas into the processing chamber of the film forming apparatus; and a step of heating the processing chamber.

This invention provides a new film forming method in which, on the occasion that pressure is decreased by pressure decreasing means which was connected to a film forming chamber, and a film is formed by evaporating an organic compound material from a deposition source in the film forming chamber, minute amounts of gas (silane series gas) which comprises smaller particles than particles of the organic compound material, i.e., a material with a smaller atomic radius are flowed, and the material with a small atomic radius is made to be included in an organic compound film.

The invention discloses a household cleaning robot capable of establishing a map by self and a cleaning method. The household cleaning robot comprises a casing, a control center arranged in the casing, a power supply module, a storage unit, a camera, a lighting alarm device, an ultrasonic wave sensor, an infrared sensor, a photosensitive sensor, a wireless module and an RFID reader-writer, wherein the ultrasonic wave sensor, the infrared sensor and the photosensitive sensor are respectively connected with the control center, and the wireless module and the RFID reader-writer are connected with the control center. The household cleaning robot further comprises a plurality of RFID labels bonded under the periphery of a wall, wherein the RFID labels are used for recording position coordinate information and are active RFID labels. The cleaning robot can establish the indoor two-dimensional map to achieve the indoor location function and acquire the coordinate points in a room. Walking areas and non-walking areas are marked on the two-dimensional map, so that the cleaning robot can quickly determine a cleaning path and accurately reach a target to be cleaned. To hygienic dead angles which cannot be cleaned, the cleaning robot is manually operated and controlled to automatically store operation and control data. When the hygienic dead angles are cleaned again, the stored operation and control data can be called to clean the target.
