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.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an embodiment of the present invention is shown: a full-automatic vacuum type hand dryer for operating rooms comprises a machine body shell 1, fans 2, a heater 3, a hand drying area 4, an inclined air outlet duct 5, a straight air outlet duct 6, an upper cover plate 7, an air inlet 8, a porous baffle plate 9, an air suction baffle plate 10, a negative pressure fan 11, a negative pressure fan air outlet 12 and sensors 13, wherein the front part, the rear part and the top part of the machine body shell 1 are respectively provided with the hand drying area, the negative pressure fan area and a functional area, the top part of the functional area is a closed space, the upper cover plate 7 is only provided with the air inlet 8 for air circulation, the functional area is internally provided with the three fans 2 and the two sensors 13, the heater 3 is arranged below the air outlet of the fan 2, the fans in the front row are uniformly and obliquely arranged on the front side of the bottom surface of the functional area through the inclined air outlet duct 5, the rear exhaust fan is vertically arranged in the middle of the, the hand drying area and the negative pressure fan area are respectively arranged at the front part and the rear part below the functional area, the joint of the hand drying area and the negative pressure fan area is longitudinally provided with a porous baffle 9, a plurality of rows of through holes are uniformly distributed on the porous baffle 9, and the aperture of the through holes is gradually increased from top to bottom; an air suction baffle plate 10 is installed on the rear side of the porous baffle plate 9, a negative pressure fan 11 is installed at the rear end of the air suction baffle plate 10, and a plurality of negative pressure fan air outlets 12 are uniformly distributed on the outer edge of the negative pressure fan 11. The heater 3, the fan 2, the sensor 13 and the negative pressure fan 11 are all electrically connected to a controller (not shown in the figure), the controller can be installed at any vacant position of the machine body shell 1, and the controller is the prior art, and therefore the description is omitted.

In this embodiment, the wind blown by the front row of fans 2 forms a certain angle with the horizontal plane, and the inclined plane at the bottom of the housing 1 also plays a role of guiding the wind to the bottom of the porous baffle 9. The negative pressure fan 11 is a fan with power larger than that of the fan 2, the air suction capacity of the negative pressure fan 11 is higher than that of the fan 2, and the air sucked by the negative pressure fan 11 comprises air stretching from the hand drying area 4 and air blown out by the fan 2, so that the air disturbance of injection in the operating room can not occur, and the dust and pathogenic bacteria can not be diffused.

During specific use, medical personnel stretch into dry hand region 4 with abluent both hands, and inductor 13 detects the hand and stretches into this moment, sends control command and lets dry hand ware begin work, and three fan 2 at top start, and clean air in the operating room is by 8 three fan 2 of flow direction of air intake, blows out powerful wind to dry hand region 4, and the wind blows the moisture that both hands surface will be on hand and takes away. Meanwhile, the negative pressure fan 11 also starts to work, the air in the hand drying area 4 is sucked to the air suction baffle plate 10 through the porous baffle plate 9, and the air at the air suction baffle plate 10 is exhausted out of the air outlet 12 of the negative pressure fan after passing through the negative pressure fan 11. The heater 3 is arranged below the fan 2, so that the hand drying effect can be achieved more quickly. The through holes of the porous baffle 9 are regularly distributed, the holes on the upper part are smaller, the holes on the lower part are larger, and the wind can flow through the bottom of the larger holes on the lower part after passing through two hands as much as possible.

The invention can play a role in quickly drying hands and reduce the dependence and waste on the hand wiping paper; but also can keep the air in the operating room stable and not to be mixed, and avoid the influence on the operating process caused by the dust and germs in the operating room flying with the wind driven by the air outlet of the hand dryer.
