Abstract
The utility model belongs to a bacteria filtration ventilation membrane, which comprises an upper screen, a non-woven fabric, a super fine glass fiber screen, and a lower screen. The pore of non-woven fabric is less than one micrometer and less than 0.5 micrometer for the super fine glass fiber net. The bacteria filtration ventilation membrane is respectively provided with a fixed frame around, and the fixed frame is corresponding to the wall and adopts soft or rigid frame. The soft frame is fixed with an upper nylon joint or an upper zipper and the rigid frame is made of aluminum alloy. The bacteria filtration ventilation membrane is convenient in assembly and dismantle and good in ventilation, and can prevent the dust and bacteria, thus being particularly suitable for operation in the field (field operation) or mobile aseptic operation room.
Description
Technical field: the utility model belongs to a kind of bacteriological filtration air ventilation membrane, and it is specially adapted to field (field operations) or portable aseptic operating room.
Background technology: present existing operating room or desinfection chamber are general all in fixing building, and bacteriological filtration, ventilating to reach desirable requirement.But in portable or open-air (field operations) building of temporarily building, want bacteriological filtration, ventilating to reach desirable requirement, then because environment and condition restriction may comparatively time-consuming troubles.
Summary of the invention: but the bacteriological filtration air ventilation membrane that provides a kind of bacteriological filtration of being convenient to load and unload to ventilate again is provided the purpose of this utility model.
The technical solution adopted in the utility model: it is characterized in that the bacteriological filtration air ventilation membrane is followed successively by mesh screen, nonwoven, following mesh screen from top to bottom, the hole of this nonwoven is less than 1 micron.
Respectively be provided with a fixed border, the soft frame of the corresponding employing of fixed border around the bacteriological filtration air ventilation membrane with body of wall.Be fixed with velcro on the soft frame or go up slide fastener.
It is characterized in that the bacteriological filtration air ventilation membrane is followed successively by mesh screen, nonwoven, ultra-fine fibre glass net, following mesh screen from top to bottom, the hole of this nonwoven is less than 1 micron, and the hole of this ultra-fine fibre glass is less than 0.5 micron.
Respectively be provided with a fixed border, the corresponding employing of fixed border hard frame around the bacteriological filtration air ventilation membrane with body of wall.Hard frame aluminum alloy frame.
The utlity model has following advantage: easy to loading and unloading, ventilated good; Because the hole of nonwoven is less than 1 micron, the hole of ultra-fine fibre glass can block dust and bacterium less than 0.5 micron, is specially adapted to the operation of field (field operations) or portable aseptic operating room.
Description of drawings: Fig. 1 is the utility model velcro formula border structure schematic diagram
Fig. 2 is the utility model aluminium alloy formula border structure schematic diagram
1. is the hard frame among the figure, 2. is last mesh screen, 3. is nonwoven, 4. is the ultra-fine fibre glass net, for following mesh screen, 6. is soft frame 5., 7. is last velcro.
The specific embodiment: this bacteriological filtration air ventilation membrane is made up of last mesh screen 2, nonwoven 3, following mesh screen 5, and the bacteriological filtration air ventilation membrane is followed successively by mesh screen 2, nonwoven 3, following mesh screen 5 from top to bottom, and the hole of this nonwoven 4 is less than 1 micron.Be fixed in the fixed border around the bacteriological filtration air ventilation membrane.
When open-air or portable aseptic operating room are soft material formation body of wall (as tent), then fixed border also adopts corresponding soft frame 6, and the bacteriological filtration air ventilation membrane can directly be sewn on upper and lower soft frame 6 outer ends.The body of wall that is made of soft material can adopt banded velcro 7 formulas or zip mode.
As adopt banded velcro 7 formulas: then around soft frame 6, hold the outside to make velcro 7 on the band shape, on velcro is fixed on around soft body of wall (as the tent) window frame under the band shape corresponding with velcro on the band shape 7.During installation, the following velcro that the last velcro 7 corresponding soft body of wall window frames on the soft frame 6 of bacteriological filtration air ventilation membrane are housed compressed both glued and to fix.
As adopt zip mode: then around soft frame 6, hold the outside to make slide fastener, on the following slide fastener corresponding with last slide fastener is fixed on around the soft body of wall window frame.During installation, be equipped with last slide fastener on the soft frame 6 of bacteriological filtration air ventilation membrane align with following slide fastener on the soft body of wall window frame haul slider of zipper fastener along around both pulled on and can fix.
The specific embodiment: this bacteriological filtration air ventilation membrane is made up of last mesh screen 2, nonwoven 3, ultra-fine fibre glass net 4, following mesh screen 5, the bacteriological filtration air ventilation membrane is followed successively by mesh screen 2, nonwoven 3, ultra-fine fibre glass net 4, following mesh screen 5 from top to bottom, the hole of this nonwoven 3 is less than 1 micron, and the hole of this ultra-fine fibre glass 4 is less than 0.5 micron.Be fixed in the fixed border around the bacteriological filtration air ventilation membrane.
When open-air (field operations) or portable aseptic operating room were the window frame of aluminum alloy frame structure, then fixed border also adopted corresponding aluminum alloy frame, and the bacteriological filtration air ventilation membrane is fixed in the aluminium alloy fixed border 1.
During installation, will be equipped with fixing " U " type aluminium alloy groove on the fixed border 1 corresponding hard body of wall window frame of bacteriological filtration air ventilation membrane, from " U " type muzzle of groove both draw can, aluminum alloy frame is difficult for jumping out when vehicle jolts from " U " type muzzle of groove.
Use this bacteriological filtration air ventilation membrane, easy to loading and unloading, ventilated good, can block dust and bacterium, be specially adapted to the operation of field (field operations) or portable aseptic operating room.
