Abstract: The invention is applicable to the field of medical care products, and provides a wound care apparatus. The wound care apparatus comprises a pump and a sealed dressing connected to the pump via a first pipeline, a laser being disposed at the upper end of the sealed dressing. The wound care apparatus further comprises a pus bottle that is connected with a piece of sponge and the pump via rubber hoses, respectively. In the invention, the pump of the wound care apparatus is connected with the sealed dressing via the first pipeline, after the wound is dressed by the sealed dressing, the pump is controlled to pump the wounded area into a vacuum state, and ulceration caused by airborne bacterial infection is thus prevented. More importantly, the wound healing rate under a near-negative pressure environment is two to three times of that under normal environment.

Abstract: The present invention claims a wireless bedwetting alarm and a disposable diaper product comprising the alarm, wherein the alarm comprises a sensor component, an RFID reader, and an alarm terminal; the sensor component is a passive RFID tag or a moisture sensor; the sensor obviates the need for a standalone power source apparatus for power supply; power is supplied by receiving and converting into electricity the energy wirelessly emitted by the RFID reader, or by obtaining body energy, temperature, or movement of the body of a user; the RFID reader uses a wireless mode for transmitting a signal to the alarm terminal to raise an alarm. The present invention adopts passive technology, obviates the use of battery, and is convenient to use, disposable, harmless to human, and of low costs.

Abstract: A solar energy collection system that can be retrofitted into pavement covered lots, such as macadam covered parking lots has a pump and heat exchanger, and a conduit buried below the pavement surface that contains a heat transfer fluid such as water. The conduit has a hollow unitary, one piece casing with an oval cross section and an internal divider that divides the interior of said casing into two passageways having substantially the same cross sectional area. Heat conducting fins preferably made of copper are mounted on the casing and extend coaxially outwardly in opposite directions therefrom along the major oval axis.
