Description
Technical field
The utility model relates to a kind of medical protection device, a kind of medical air draft protective gear that prevents virus and bacterium by infection through air that is specifically related to that medical institutions' outpatient service such as hospital, sick bed place use.Use this device can effectively prevent medical care personnel when treating as patient, self and other relevant personnel are by virus and bacterial infection.
Background technique
As everyone knows, virus and bacterium all are a kind of tiny organisms, and they can depend on the dust or the spittle usually and scatter everywhere by flowing of air, and are hard to guard against.Be familiar with deficiency owing to people propagate bacterium and virus, and ventilation is smooth, protective measure is ineffective, the epidemic victim very easily causes cross infection in hospital, clinic when going to a doctor, and serious threat medical care people reach the relevant personnel's safety at one's side.Winter last year and one period of spring in this year, SARS virus is popular to be exactly a deep lesson.For the epidemic victim, medical care personnel must carry out diagnosis and treatment face-to-face, but how about effectively protect, and have caused people from all walks of life's great attention.For this reason, the utility model is from effectively preventing medical care personnel for patient's diagnosis and treatment the time, and the relevant personnel were set out by the angle of virus and bacterial infection around self reached, and had designed a kind of medical air draft protective gear, to overcome deficiency of the prior art.
Summary of the invention
For achieving the above object, the technical solution adopted in the utility model is: a kind of medical air draft protective gear comprises roughing efficiency air filter, high efficiency particulate air filter, centrifugal blower and safety cover structure; High efficiency particulate air filter, roughing efficiency air filter and centrifugal blower are formed a suction air flue structure, and wherein, roughing efficiency air filter, high efficiency particulate air filter are positioned at the logical intake grill end of suction wind successively, and centrifugal blower is positioned at the air opening end of high efficiency particulate air filter; Safety cover is an introducing-type fan housing body structure, and the intake grill in suction air channel is located in the safety cover, constitutes a negative-pressure type high-efficiency air filtering passage with this.
The content and the change interpretation of technique scheme are as follows:
1, in the such scheme, described high efficiency particulate air filter is the air filter of a kind of filtration the 〉=0.1 μ m particle diameter dust, and such as the high efficiency particulate air filter of glass fibre material type, this filter can filter out 99.999% dust in the air.High efficiency particulate air filter concrete structure and will ask for an interview to GB13554-92 NBS " high efficiency particulate air filters ".Roughing efficiency air filter is a kind of simple gross porosity air filter, such as nonwovens, Stainless Steel Wire screen cloth and micropore sponge etc.
2, in the such scheme, wind-guiding cover body, suction air channel and filter can be combined into vertical and horizontal two kinds of basic structures:
(1), vertical structure
Described wind scooper body structure is made up of frame and some baffle plates; frame is a frame structure; baffle plate is installed on the framework and constitutes cover body; the front of cover body is provided with window; the suction air channel is located at the upper rack space; wherein, the intake grill in suction air channel is located at the cover body top, constitutes vertical air draft protective gear with this.This structure is applicable to hospital outpatient, and epidemic victim's seat is in the wind-guiding cover body during use, and the doctor sits outside the cover, diagnoses for patient and treats by window, and the patient expired air and the spittle are after filtration, the suction air channel comes indoor or outdoors.
For patient expired air is kept off in cover, liftable front screen can also be set, in the diagnostic window in cover body front to stop patient expired air-flow.
Vertical structure can be designed to the structure of a plurality of isolation ward overall alignment, also can be designed to stand-alone configuration, and wherein a plurality of isolation wards in the overall alignment structure can aspirate the air channel by a shared cover, also can design independent suction air channel separately; The frame bottom of stand-alone configuration can be installed castor and is convenient to move.
(2), horizontal type structure
Described wind scooper body structure is the wind-collection cover on the similar cooker hood, and suction air channel and wind-collection cover are fixedly connected into integral body, and the intake grill that wherein aspirates the air channel is located at the top or the sidepiece of wind-collection cover, constitutes horizontal air draft protective gear with this.This structure is applicable to hospital ward, and this device is installed in the sick bed above-head during use, and the doctor is other for patient diagnoses and treats at sick bed, the air that the epidemic victim breathes out and the spittle after filtration, aspirate the air channel and come indoor or outdoors.
3, in the such scheme,, can on the inwall of wind-guiding cover body, ultraviolet germicidal lamp be installed in order immediately effectively to kill virus and the bacterium that is adsorbed on high efficiency particulate air filter and the wind scooper inwall.This ultraviolet germicidal lamp is installed in best results on the position of comprehensive irradiation high efficiency particulate air filter surface and wind scooper inwall.Ultraviolet germicidal lamp does not need long-term work, generally can carry out sterilization after use.
4, in the above scheme, centrifugal blower and ultraviolet germicidal lamp can be controlled by power supply, switch or control panel, and wherein, centrifugal blower also can be adopted infrared inductor and control automatically.Adopting centrifugal blower is because this programme needs bigger negative pressure, could keep proper functioning.
The utility model working principle is: place in the safety cover patient or the below during use; centrifugal blower energising back medical care personnel are in windward; patient is at a disadvantage; air flows in the cover outward by safety cover; discharge after through high efficiency particulate air filter, thereby avoid infection medical care personnel with patient expired air-filtering.
Virus and bacterium can depend on the dust or the spittle usually and blaze about by flowing of air, because the negative pressure-pumping effect, the air dust-free sterile that the air of these pollutions is discharged after high efficiency particulate air filter filters is so can directly come indoor or outdoors.Be equipped with ultraviolet germicidal lamp in the safety cover, can be regularly or not timing carry out sterilization.In addition, roughing efficiency air filter rises makes auxiliary protection function, to prolong the working life of high efficiency particulate air filter.
Because the technique scheme utilization the utlity model has following advantage:
1, the utility model is a kind of medical air draft protective gear that prevents virus and bacterium by infection through air, and it can effectively prevent medical care personnel when treating for patient, and self and other relevant personnel are by virus and bacterial infection.
2, the utility model is divided into vertical and horizontal two kinds of structural types, is applicable to hospital outpatient respectively and the ward of being in hospital.
3, the utility model high efficiency particulate air filter and roughing efficiency air filter can be changed after decreasing and imitating.
4, the utility model is simple in structure, easy to operate, applicability is strong, both can be widely used in medical spaces such as hospital, also can be applied to research and experiment place that laboratory etc. needs the dust-free sterile discharging.
