Abstract: A toothbrush includes a head portion having bristles thereon, a neck portion, and a handle. One end of the neck portion is connected to the head portion, and the other end is connected to the handle. The axis of the bristles is substantially parallel to the axis of the neck portion. The axis of the neck portion and the axis of the handle form an angle. Accordingly, the toothbrush can be used easily for brushing, and it reduces angle limitations when cleaning the inner surface of teeth.

Abstract: A portable oxygen generating system comprises a reaction chamber having at least a first storage compartment for containing a first reacting substance and a second storage compartment for containing a second reacting substance, a dispensing mechanism operable to cause the first and second reacting substances to contact with each other so as to create a chemical reaction to produce an oxygen gas, and a gas outlet for delivering the produced oxygen gas. To use the system, the user pushes on a switch to initiate the production of oxygen.

Abstract: A respiratory mask comprises a mask body and a filter system. The filter system includes a replaceable filter cartridge accommodating a filtration material separable into a plurality of portions, and a filter chamber connected to the mask body and configured to receive one portion of the filtration material. To change the filtration material, a user removes a first portion of the filtration material from the filter chamber, and positions a second portion of the filtration material contained inside the filter cartridge.

Abstract: A respiratory testing system comprises a fluid chamber enclosing a fluid medium and having a flexible membrane deflectable by the application of a respiratory gas flow, a pressure sensor configured to sense a pressure variation of the fluid medium in response to a deflection of the flexible membrane, and a processing circuit configured to compute a respiratory flow data from a pressure variation of the fluid medium. The respiratory testing system may additionally include a breathing exercise unit configurable to execute a software program responsive to an input of the respiratory flow data.

Abstract: A tonometer includes a chamber containing a fluid medium and having a contact tip for contacting an eye surface, the contact tip having a flexible surface stretched by the fluid medium, a pressure sensor detecting a pressure variation of the fluid medium, a detecting mechanism determining whether the tonometer is correctly placed against the eye surface, and a processing circuit configured to treat electrical a signal received from the detecting mechanism.

Abstract: A toner cartridge is constructed to include a container for accommodating toner, the container having a filling hole portion disposed at one end for filling of toner into the container and a barrel with a discharging hole at an opposite end for output of toner to a toner-receiving container in the image forming system in which the toner cartridge is installed, a strippable seal attached to the barrel to seal the discharging hole, and a stopper coupled to the barrel and moved to close/open the discharging hole after removal of the seal from the barrel.

Abstract: A toner supplying container detachably mountable to an image forming apparatus. In one embodiment, the toner supplying container includes a first container for receiving toner and a second container for accommodating toner and providing toner to the first container. The second container is releasably mounted to the first container at a predetermined position such that the first container and second container communicate to each other. The second container is replaceable when the toner accommodated in the second container is used up by a third container that is substantially identical to the second container but has toner therein.

Abstract: A developer container in which the container body has an inwardly protruded spiral guide flange spirally extending from the rear close side to a developer supply port of the container body and defining a spiral flow guide way adapted to guide developer from the inside of the container body to the outside of the container body through the developer supply port, wherein the developer supply port having a recessed developer accumulation area and a through hole through the center of the recessed developer accumulation area, the spiral guide flange has a beveled guide face extending to the recessed developer accumulation area.

Abstract: A toner cartridge opening control arrangement is constructed to include a toner cartridge for accommodating toner, the toner cartridge having an opening for output of the toner into a toner receiving container, a removable sealing member adapted to close/open the opening of the toner cartridge, a force applying member for receiving an external pulling force to move the removable sealing member, a magnetism device for imparting an outward pressure to the force applying member, and a releasable locking device adapted to lock the force applying member.

Abstract: A toner container is constructed to include a toner storing portion for accommodating toner, a supply opening adapted for guiding toner from the toner storing portion to a toner receiving portion connected to the toner storing portion, a removable sealing member sealing the supply openings, and two elastic members provided at two sides of the toner storing portion and adapted for pushing the toner storing portion away from the toner receiving portion upon disengagement of the toner storing portion from the toner receiving portion.
