Abstract
The utility model discloses combine to use for 203683545U is used for the real -time sampling device of blood culture bottle pressure detection for open number, the pressure detection needle that will be arranged in the real -time sampling device of blood culture bottle pressure detection passes the bottle plug and shen ru carries out continuous monitor to the interior culture medium of bottle. The utility model discloses a culture medium adopts the dilution method to obtain, and it is legal to be different from in the antibiotic resin among the prior art, easily realizes, the blake bottle adopts glass or plastics material, production simple process, the blood blake bottle cooperates the pressure monitoring device, is not subject to prior art's CO2's limitation, adopts pressure variation to determine and has or not the bacterium to grow, detects sensitivelyer, magnetic stirring in the blood blake bottle is different from prior art's whole shock mode, guarantees the oxygenate growth demand of bacterium in every bottle, shortens check -out time.
Description
Technical field
The utility model relates to a kind of medical detecting Instrument equipment, especially relates to a kind of biological specimen flashing lightning magnetic field detector.
Background technology
In hospital clinical and medical research test, blood cultivation is one of a kind of most important and modal inspection.At present import is mainly relied on to be main for the instrument of blood cultivation and supporting flashing lightning magnetic field detector clinically, have the Bactectm9000 of U.S. company BD series and French Mei Liai Bact/Alert3D, they adopt the method for fluorescence or color sensing to observe the CO produced in bacteria growth process
2variable quantity judged whether bacterial growth, this detection method is comparatively accurate, but has some limitations in actual clinical, for generation trace amounts of CO
2or produce CO
2gas in addition has detection leakage phenomenon.
Summary of the invention
For solve that existing blood cultivation exists in actual clinical for generation trace amounts of CO
2or produce CO
2gas in addition has the limitation of detection leakage phenomenon, and the utility model provides a kind of biological specimen flashing lightning magnetic field detector.
The technical solution adopted in the utility model is: a kind of biological specimen flashing lightning magnetic field detector, and the substratum comprising bottle stopper, bottle and be arranged in bottle, is characterized in that: in described bottle, below is also provided with magnetic stirring bar.
As preferably, described bottle upper end is provided with two openings.
As preferably, described bottle material is glass or plastics.
The beneficial effects of the utility model are: substratum of the present utility model adopts dilution method to obtain, and it is legal to be different from pae resin of the prior art, are easy to realize; Culturing bottle adopts glass or plastic material, and production technique is simple; Flashing lightning magnetic field detector coordinates pressure monitoring device, is not limited to the CO of prior art
2limitation, adopt pressure change determine whether bacterial growth, detect sensitiveer; Magnetic agitation in flashing lightning magnetic field detector, is different from the entirety concussion mode of prior art, ensures the oxygenate growth demand of bacterium in each bottle, shortens detection time.
Accompanying drawing explanation
Fig. 1 is contour structures schematic diagram of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model.
Embodiment
The technique means realized to make the utility model, character of innovation, achieving the goal is easy to understand with effect, is described further below in conjunction with accompanying drawing 1,2 pairs of the utility model.
As shown in Figure 2, a kind of biological specimen flashing lightning magnetic field detector, the substratum 3 comprising bottle stopper 1, bottle 2 and be filled in bottle 2, bottle 2 is sealed to the culture vessel of a sealing by bottle stopper 1, wherein: bottle 2 interior bottom portion is also provided with magnetic stirring bar 4, bottle 2 upper end is provided with two openings, and opening is used for pressure detection, and what opening was used for culture exempts from sampling of uncapping.
When the utility model uses, first magnetic stirring bar 4 is set in bottle 2, with one of them opening of bottle stopper 1 sealed bottle body 2, the substratum 3 of filling certain demand, bottle 2 is vacuumized another opening that rear bottle stopper 1 covers bottle 2, adjustment bottle 2 internal gas pressure, forms 6 ~ 10ml negative pressure, through autoclaving, labelledly to complete.
The utility model is that 203683545U uses for Blood culture bottle pressure detection real time sample device in conjunction with publication number, the pressure detection pin being used for Blood culture bottle pressure detection real time sample device is deep into through bottle stopper 1 in the substratum 3 in bottle 2 and monitors continuously, when proofing unit detect in Blood culture bottle have pressure change time, illustrate in Blood culture bottle have air release or consumption, be convenient to researchist and accurately judge whether blood sample pollutes in real time.
The one of the more preferably embodiment of the just the utility model described by above-described embodiment, the simple change that those skilled in the art carries out within the scope of the technical program and replacing all should be included in protection domain of the present utility model.
Claims (2)
