Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a hand dryer, and particularly relates to a full-automatic vacuum hand dryer for an operating room.
Background
The operation personnel need to clean and dry hands and forearms before operation, the operation is strictly carried out according to a disinfection isolation system in an operating room, the hands and the forearms are cleaned and then dried by using hand wiping paper, but the resource waste is caused by using a large amount of disposable hand wiping paper every day. And the washed hands are easy to leave paper scraps after being wiped by toilet paper, and are easy to cause pollution in the operation.
Common hand dryer on the market mainly blows out wind with faster speed with the fan, and just abluent both hands are put below the air outlet, and the inductor detects can begin to supply air and blow certain time behind the hand to reach the purpose that makes hand and forearm dry. If necessary, a heating device is also added in a channel through which the air flows, and the air with heat is blown out, so that the hand can be dried more quickly. Since the operating room has a strict disinfection and isolation system, and the air sent into the operating room needs to be purified by adopting laminar flow of filtering and ventilating, the existing spray type hand drying device is not allowed to be used in the operating room, and the existing spray type hand drying device is easy to cause the diffusion of dust and pathogenic bacteria in the operating room, so that the improvement of the existing hand drying device is needed.
There are also hand dryers (see e.g. patent No. 201720107715.6) which operate on the principle of negative pressure, and which draw air through a negative pressure fan in an attempt to remove the water from the washed hands. Although the device can achieve certain effect in principle, the device can not cause great disturbance to the air in an operating room and the diffusion of dust and pathogenic bacteria. But in practical application, the wind speed at the wind suction side is very slow, and the effect of quickly drying hands cannot be achieved.
