A reduced-pressure device for wound treatment includes a housing, an air pressure storage unit, a compression unit and a pressure indicating module. The air pressure storage unit is installed in the housing and comprises a pressure storage container, a piston assembly and a piston spring, and the compression unit is mounted on the piston assembly, and the pressure indicating module is engaged to the pressure storage container and the piston assembly. Therefore, the user can see the information shown on the pressure indicating module to be easily aware of how much capacity of negative pressure the reduced-pressure device can continuously be provided in order to determine when to operate the compression unit again for providing the desired negative pressure.

Reduced-pressure device

A reduced-pressure device includes a housing having recesses on sidewalls thereof, an air pressure storage unit and a compression unit. The air pressure storage unit is installed in the housing and comprises a pressure storage container, a piston assembly and a piston spring, and the compression unit is mounted on the piston assembly. The compression unit further includes a pressing element and a turntable. The pressing element is accommodatable in the recesses of the housing, and rotatable by the turntable in relative to the air pressure storage unit and the housing, and when the pressing element is pulled out of the recesses and rotated to a predetermined position to compress the piston assembly to produce a negative pressure in the pressure storage container, the pressing element can be rotated back to the original position to be accommodated in the recesses again after using.

A portable negative-pressure device including a housing, a piston, a barrier layer and a spring means for forming a first collection chamber and a second collection chamber having a variable volume to form a pressure-reducing region is provided. In the situation of that the exudates have been stored in the first collection chamber, the portable negative-pressure device can still maintain a sufficient negative pressure by continuously compressing the piston, and the second collection chamber will provide an additional liquid storage space.

An input module for use with an electronic device (for example, a PDA) is provided. The input module includes an adapter and an input device. The adapter includes an adjustment mechanism, and the input device includes a connection portion and a main body. When the input device is connected with the adapter, the adjustment mechanism allows the connection portion in a specific position and coupling with the electronic device electrically.

Input module and apparatus using the same

An input apparatus having a scrolling function includes a cursor key and a hot key. The cursor key is configured to selectively control a cursor movement on a screen and scroll data displayed on the screen. When the hot key is at a first status, in response to action of a user, the cursor key scrolls data displayed on the screen. When the hot key is at a second status, in response to action of the user, the cursor key controls the cursor movement on the screen. Methods for selectively providing a scrolling function on the input apparatus are also provided.

Input apparatus with scrolling function on cursor key and method thereof

The present invention provides a detachable data input device for use with a portable electronic apparatus. The data input device such as a keyboard includes a connecting device, a housing, and an adjustment unit. The connecting device includes at least one projection and a first slot. The housing has a second slot and an angle is formed between the extending directions of the first slot and the second slot. The adjustment unit is movable between a first end and a second end of the second slot and is pivotally connected to the connecting device by passing through the first slot and the second slot. When the adjustment unit moves to the first end, the projection extends out of the housing by a first length. When the adjustment unit moves to the second end, the projection extends out of the housing by a second length. The first length is different from the second length.

Portable electronic apparatus and detachable input device thereof

An input device with a number of key sets is described. The input device has a first state when the key sets are configured in different levels, and a second state when the key sets are configured to be side-by-side.

Input device

A collapsible keyboard includes a keyboard base, at least one section hinge, a key base, at least one fixed hinge, at least one movable hinge and a plurality of keys. The keyboard base has a plurality of first sections. The section hinge connects the plurality of first sections so that the first sections are rotatable with respect to each other. The key base has a plurality of second sections provided on the first sections. The fixed hinge connects the second sections so that they are rotatable with respect to each other. The movable hinge connects one of the first sections and one of the second sections. The keys are provided on the second sections.

Collapsible keyboard

Various embodiments of the present invention relate to an electronic instrument holding device and, more particularly, to an electronic instrument holding device having a circuit board. The present invention holds an electronic instrument at a predetermined angle and connects an input device to the electronic instrument so that a user may input information into the electronic instrument with a comfortable viewing angle. A circuit board may also be equipped on the electronic instrument holding device to replace or enhance the board disposed inside the input device so that manufacturing and assembling the input device are accelerated.

Electronic instrument holding device

An external input device for a portable computer or personal digital assistant (PDA) has at least one rotatable sideboard. The sideboard operates in two states. When the sideboard is in the first state, the sideboard protects the key sets, and when the sideboard is in a second state, the sideboard facilitates input operation of user.

The present invention relates to a foldable keyboard, and more particularly, to a foldable keyboard adapted for a point stick and/or at least one hot key. Two or more keypad portions are hingably connected by a connection board on which a point stick or at least one hot key is disposed. When the keyboard is in a deployed configuration, the keypad portions slide along the keyboard plane to combine with the point stick or the hot keys so that a complete keyboard is formed. The connection board of the present invention may further include a circuit board to be electrically connected with each key and the point stick or the hot keys in order to receive and decode the signals from each key and the point stick or the hot keys.

Foldable keyboard with point stick

An input apparatus for holding and cooperating with electrical devices such as personal digital assistants (PDAs) having different sizes includes a housing, an input interface, and a cap. The housing includes a front plate, a bottom plate, and two side portions, and the cap is disposed between the two side portions. The cap and housing together form a first space to contain an electrical device with a smaller size when cap is positioned in a top position. Also, the cap may be moved to a bottom position to form a second space for containing an electrical device with a larger size.

Input apparatus cooperating with electrical device
