Abstract
The utility model discloses a negative pressure protective hood which comprises a top hood and a transparent face mask installed on the lower end of the hood, wherein a transparent soft hood is arranged in the face mask, and an exhaust filter device is connected on the rear portion of the face mask through a hose, and is connected with a power supply device. The inner portion of the negative pressure protective hood is in the negative pressure state corresponding to the outside of the hood, namely air flows in the hood from the outside, and is prevented from diffusing around, thereby protecting retinue and the environment.
Description
Technical field
This utility model relates to a kind of medical supplies, relates in particular to a kind of negative pressure Protective clothes combined with cap and mask.
Background technology
Over the past thousands of years, infectious disease, especially respiratory diseases are perplexing the mankind always.The disease that pathogen is invaded, propagated and cause from respiratory tract infection is called respiratory infectious disease.
Respiratory tract is a human body from nose oxygen intake and the passage that gives off carbon dioxide from lung.Comprise nasal cavity, pharynx, larynx, trachea, bronchus, bronchioles etc.Medically nose, pharynx, larynx are called respiratory tract, trachea, bronchus are lower respiratory tract.Respiratory tract and exterior are subjected to the chance of various pathogen invasion and attack more, the pathogen that respiratory tract enters, and original parasitic site is respiratory mucosa and lung normally.
Common respiratory infectious disease has influenza, measles, chickenpox, rubella, epidemic cerebrospinal meningitis (abbreviation epidemic encephalitis) etc.
Influenza has very strong infectiousness by the acute respiratory infectious disease that influenza virus causes, its sickness rate accounts for position first of the infectious disease.The source of infection of influenza mainly is patient and inapparent infection person, and infective stage was 1 week.Influenza is directly propagated based on the air spittle, also can pass through by the article infect indirectly of viral pollution.The crowd has certain immunity after being ill to the general susceptible of influenza, can keep more for a long time to isostructural immunity, and to cross immunity power is also arranged between the mutation of same hypotype, but the time of keeping is not long, and virus constantly morphs, and can cause the repeated infection morbidity.Influenza all can be fallen ill the whole year, sees with the Winter-Spring more.Isolating a patient is to reduce the effective way of propagating, and isolation period was 1 week.Epidemic period is avoided public meeting as far as possible, and indoor attention is ventilated.
So, invasion and attack in the face of infectious disease, especially respiratory diseases, have the mankind really felt simply helpless? the fact shows, pay attention to the hazardness of infectious disease, reinforcement is to the research of infectious disease, set up complete monitoring system, carry out effectively control, immune means, the mankind have the ability to control or even eliminate some infectious disease fully.
With the struggle of respiratory infectious disease in, pay attention to prevention, early stage control can play a multiplier effect, and is the best approach that tackles infectious disease.
Protective clothes combined with cap and mask is provided with for the prevention and control of in time carrying out respiratory infectious disease, and the isolating and protecting when it is applicable to the epidemic victim shifted plays a protective role to entourage and environment.
But existing Protective clothes combined with cap and mask is generally selected materials such as no gauze filtrate and spun laced fabric powdered activated carbon for use, and the air that wearer is breathed out filters directly discharging of back, and Protective clothes combined with cap and mask inside is barotropic state, and protection effect is bad.
The utility model content
This utility model technical issues that need to address just are to overcome existing Protective clothes combined with cap and mask inside and are barotropic state, protection effect defect of bad; a kind of negative pressure Protective clothes combined with cap and mask is provided; described negative pressure Protective clothes combined with cap and mask inside is negative pressure state with respect to the head-shield outside; be air-flow by outer flow to head-shield inside; prevent that air to diffusion all around, playing a protective role to entourage and environment.
For addressing the above problem, this utility model adopts following technical scheme:
A kind of negative pressure Protective clothes combined with cap and mask of this utility model, described Protective clothes combined with cap and mask comprises the head-shield at top and is installed on the transparent face mask of head-shield lower end, be provided with the soft guard shield of layer of transparent in the described face shield, described face shield rear portion is by a hose connection air draft defecator, and described air draft defecator is connected with supply unit.
Described supply unit is rechargeable uninterrupted battery supply.
Described supply unit is provided with a belt or braces.
Described face shield both sides are respectively equipped with the audition aperture with respect to human body ear position.
Described air draft defecator and supply unit are installed on the movable wheelchair.
This utility model is a kind of negative pressure Protective clothes combined with cap and mask that prevents the infectious disease diffusion function that has, and is applicable to the isolating and protecting the when epidemic victim shifted.The air that it is breathed out to face mask wearer by the air draft defecator aspirates, filtering emission, and expellant gas filters the back through default high efficiency particulate air filter and discharges.During use, keep the negative pressure state in the face shield, negative pressure head-shield inside is negative pressure state with respect to the head-shield outside, promptly air-flow by outer flow to head-shield inside.Prevent that air to diffusion all around, playing a protective role to entourage and environment.Face shield and soft guard shield all adopt transparent material to make, and can conveniently observe the wearer.
Protective clothes combined with cap and mask described in the utility model can cooperate removable instrument such as wheelchair to use, and the weight that all are supporting all can be placed in as air draft defecator and supply unit on the movable equipment such as wheelchair.When using movable equipment such as wheelchair, the negative pressure Protective clothes combined with cap and mask can also be lifted on the support that movable equipment establishes in advance, eliminate patient fully and bear a heavy burden.
Described face shield both sides are respectively equipped with the audition aperture with respect to human body ear position.Make things convenient for patient and exchanging of personnel on every side.
