Technical field
The present invention relates to a kind of hydraulic shock air microbe sampling device, sample collecting when can be used in the air microorganism detection.
Background technology
The hydraulic shock air microorganism sampler is based on the cleaning and the spraying principle of air-flow, is captured in airborne microorganism or biogenic toxin particulate in a kind of device in the liquid medium of sampling thief.This sampling thief feeds in the liquid medium in the sampling thief detecting gas appearance at work, utilizes good physics of medium and biological property, and microorganism or biogenic toxin gasoloid are captured.With respect to the sampling thief of other principle, this device has capture rate height, liquid medium and microorganism or biogenic toxin are had better protect effect, post-processed comparatively simply reaches advantages such as easy to use.
Hydraulic shock formula sampling thief can be divided into three kinds of high-speed straight-line impact type, high speed tangent line impact type and speed straight line impact types etc. by the gentle stream impact direction of its sampling flow velocity, and wherein first kind of sampling thief is the most commonly used.Greenburg and Smith use the hydraulic shock sampling thief that air dust is sampled in nineteen twenty-two first; During～nineteen fifty-one in 1948; U.S.'s Biological Warfare Research Center Detrick fort and the Britain's Biological Warfare Research Center bohr institute of microbiology of pausing; To its physical arrangement, the capture effect and the method for sampling have been carried out detailed research in succession, and use it as the aerocolloidal reference instrument of research experiment air microbe.Wherein full glass impact sampling device (AGI) is proposed as the standard sample device in first international aerobiology meeting.
Summary of the invention
The object of the invention provides a kind of hydraulic shock formula air microorganism sampler, and this sampling thief is used for the collection of the multiple microbial aerosol of routine experimentation chamber test.
The present invention realizes through following technical scheme: the whole processing of high molecular material that adopts of sampling thief forms, and macromolecular material comprises: gather carbon ester, tygon, polypropylene, polystyrene, teflon; This sampling thief comprises sampling bottle 7, sampling bottle cap 6, gland bonnet 10, right-angle bending air conduit one 1-1, right-angle bending air conduit two 1-2, set nut 3, set nut " O " type circle 2, sampling lid " O " type circle 4 and gland bonnet " O " type circle 9; Wherein, sealing embeds two short air conduits 5 and long air conduits 8 that interior external diameters are identical on the sampling bottle cap 6, is encased inside sample bottle cap " O " type circle 4 and sampling bottle 7 in the sampling bottle cap 6 and is connected through thread seal; Before the work and after the sample collecting completion, the short air conduit 5 on the sampling bottle cap 6 adopts gland bonnet 10 sealings that are encased inside gland bonnet " O " type circle 9 with long air conduit 8; During work, adopt the set nut 3 that is encased inside set nut " O " type circle 2 that two identical right-angle bending air conduit one 1-1 and right-angle bending air conduit two 1-2 are individually fixed on the short air conduit 5 and long air conduit 8 on the sampling bottle cap 6.The air conduit length that sealing embeds on the sampling bottle cap 6 differs, and long air conduit 8 distance samples bottles bottom is 10mm～30mm, and short air conduit 5 stretches into sampling bottle 7 inner length and is no more than 1/3rd of sampling bottle 7 body length; It is 10mm～50mm that short air conduit 5 exposes bottle cap length with long air conduit 8 tops, and short air conduit 5 all has the screw thread that can be connected with gland bonnet 10 or set nut 3 with long air conduit 8 tops.Set nut 3 is fixed in right-angle bending air conduit one 1-1 and right-angle bending air conduit two 1-2 vertical component middle and lower parts; Less than short air conduit 5 length, right-angle bending air conduit one 1-1 and right-angle bending air conduit two 1-2 external diameters are less than the internal diameter that embeds air conduit 5 and air conduit 8 on the sampling bottle cap 6 apart from the length of vertical component bottom for it.
Beneficial effect of the present invention is, can gather airborne microorganism, is applicable under the field environment the aerocolloidal collection of biological sample in vehicle-mounted, the portable mobile sampling equipment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the vertical section structure synoptic diagram A sampling thief partial enlarged drawing B of hydraulic shock air microorganism sampler duty
Fig. 2 is before the work of hydraulic shock air microorganism sampler or the vertical section structure synoptic diagram A sampling thief partial enlarged drawing B of sample collecting after accomplishing
Wherein: 1-1. right-angle bending air conduit one, 1-2. right-angle bending air conduit two, 2. set nut " O " type circle, 3. set nut; 4. sampling lid " O " type circle is 5. lacked air conduit, 6. sampling bottle cap, 7. sampling bottle; 8. long air conduit, 9. gland bonnet " O " type circle, 10. gland bonnet.
Embodiment
Fig. 1 is the vertical section structure synoptic diagram of hydraulic shock air microorganism sampler duty, is encased inside sampling bottle cap " O " type circle 4 backs in the sampling bottle cap 6 and is tightly connected through screw thread and sampling bottle 7; It is 30mm that bottle cap length is exposed on air conduit top; Right-angle bending air conduit one 1-1 and right-angle bending air conduit two 1-2 part respectively insert in the short air conduit 5 and long air conduit 8 on the sampling bottle cap 6; Be tightly connected with long air conduit 8 with short air conduit 5 through the set nut 3 that is encased inside set nut " O " type circle 2 then, long air conduit 8 distance samples bottles bottom is 15mm.Sampling thief in the course of the work; Add the PBS damping fluid that is lower than cumulative volume 1/3rd in the sampling bottle 7; The horizontal port of right-angle bending air conduit one 1-1 links to each other with aspiration pump; The speed of exhaust is 1L/min, and the horizontal port of right-angle bending air conduit two 1-2 places cloth to spill in the balance bunker that the aerocolloidal volume of bacillus thuringiensis is 1L to carry out sample collecting.The long air conduit 8 of gathering the air-flow process sampling thief of coming in is accelerated to fair speed; Because the lower end of long air conduit 8 is immersed in the sample solution, most of biomone that sucks impacts at the bottom of the bottle no longer with air motion, but is retained in the sample solution; Some small-particle of not adopting possibly be diffused into bubble surface; In the collected liquid of collapse of bubbles, can know that through calculating this process sampling efficiency can reach 75%.Accompanying drawing 2 is before the work of new liquid impinging air microorganism sampler or the vertical section structure synoptic diagram of sample collecting after accomplishing; Before collected specimens or after the sample collecting completion; Short air conduit 5 seals with long air conduit 8 on the bottle cap 6 to adopt gland bonnet 10 sample, prevents that the sampling bottle of cleaning or the sample of collection from being polluted.
