Abstract
The utility model discloses a sealed head and face protection hood that can protect against harm of hazardous particles, viruses and bacteria to human body, which comprises a protection hood made of a transparent material, with respiration channels open to the ambient environment and a mask made of a filtering material connected to the respiration channels in a sealed manner; an connecting section is arranged at the opening of the protection hood, and the connecting section is in a flexible structure and is used to connect the clothing of the user, so as to isolate from the ambient air. In that way, the utility model enhances safety for the user, and has advantages such as low cost and easy operation; the utility model can not only protect the respiratory passage against infection but also protect the eyes and face and cut off the source of infection effectively and thoroughly and protect human body against hazardous particles in the air; the utility model is especially suitable for use by patients, relatives of the patients, medical staff, and visitors.
Description
Technical field
This utility model relates to a kind of protector to the harm of human body such as airborne particulates emission, virus and bacterium that is used to prevent, especially can prevent the sealed protection head mask to the harm of human body such as particulates emission, virus and bacterium.
Background technology
At present, adopt two kinds of forms in that the protection tool of employed isolation of occasions such as hospital and protective action is general, a kind of is and protective cover, the helmet of the complete seal isolation in the external world or isolate clothes that the air that its user breathes relies on the oxygen cylinder that carries to provide; Another kind is to adopt the form of directly wearing mouth mask, prevents to advance harmful particulate from infectious respiratory disease or breathing that the air that the user breathes is to rely on the air with the external world to use through mouth mask filtration, the back of sterilizing.The former isolation and protective action are better, but have following deficiency: 1, the user can not respiratory tract is infected protect in, other position of heads such as its user's eye and face is protected, its function is comparatively single; 2, are subjected to manufacturing cost height, heavy wearing, service time oxygen quantitative limitation in the oxygen cylinder, extremely impracticable and cost is higher to the personnel that need frequent operation.Latter's manufacturing cost and use cost are all lower, and it is easy to use flexible, but owing to wearing and reason such as activity of the person that wears the mouth mask, still might cause and wear imprecision etc., thereby can not effectively stop the infringement of the extremely strong virus of infectiousness, bacterium and particulates emission to human body, especially extremely strong infectious disease, the pestilence of some emerging infectiousness, as the SARS-SARS in the recent popular whole world etc., the selection improper use of protection tool and protection are not tight, all will bring bigger danger to user and crowd on every side.
The utility model content
Isolate and the isolation clothes of protective action, mouth mask etc. use inconvenience and cost high or protect the deficiency of imprecision and function singleness in order to overcome to have had now, technical problem to be solved in the utility model provide a kind of can respiratory tract is infected carry out close protection in, other position of heads such as its user's eye, face is also protected and sealed protection head mask simple in structure.
The technical scheme that its technical problem that solves the utility model adopts is: sealed protection head mask, include the protective cover of making by transparent material, and transparent material can adopt glass, lucite or other transparent plastic to make.Protective cover is provided with and the extraneous respiration channel that communicates, and this respiration channel is the breathing window that open the position of corresponding face mouth and nose on protective cover, is sealedly connected with the mouth mask that filtering material is made on the respiration channel; The opening of protective cover also is provided with linkage section, and this linkage section is a flexible structure, make as adopting cloth, fabric etc., in order to being connected with user's clothing etc., thus with the air insulated in the external world.
The beneficial effects of the utility model are, owing to adopted on the protective cover that transparent material is made respiration channel be set, and the mode of the mouth mask made of the filtering material that on respiration channel, is tightly connected, increased user's security, and has a low cost of manufacture, advantage easy to use, when infection is protected to respiratory tract, also can be to its user's eye, other position of heads such as face is also protected, and can the sound prevention infection sources, particulates emission is particularly useful for the medical worker the harm of human body in the air, the in-situ processing personnel, family numbers of patients, use among the high-risk crowd such as visiting person.
