Two elevating mechanisms.
The beneficial effects of the present invention are as follows:
This Blood culture machine increases the pump housing and plunger on culture bottle, and by puncture needle connection culture bottle and pumps intracorporal pressure
Contracting chamber, plunger under the drive of the transmission mechanism can be along the axial movements of compression chamber, when plunger moves backward and expands in compression chamber
Space, the vacuum of a part is caused in compression chamber, lower relative to the pressure in culture bottle, blood sample passes through puncture
The inner hole of needle enters in compression chamber, when plunger moves forward and squeeze the space in compression chamber, the anti-Hemostatic Oral Liquid sample of the first check valve
Originally culture bottle is flowed back to, i.e., is thrown away by nozzle, achievees the effect that automatic transferred species, efficiency are very high, moreover it is possible to realize quantitative dropping liquid
And the function of control liquid droping speed.
Detailed description of the invention
With reference to the accompanying drawing and specific embodiment the invention will be further described, in which:
Fig. 1 is the structural schematic diagram of the embodiment of the present invention；
Fig. 2 is the cooperation schematic diagram of plunger and the pump housing in the embodiment of the present invention.
Specific embodiment
Referring to Fig. 1, a kind of automatic transferred species formula Blood culture machine of the invention, including culture bottle 1, the pump housing 2 and plunger 3, institute
It states and is provided with compression chamber 4 in the pump housing 2, the upside of the compression chamber 4 is connected to inside culture bottle 1 by puncture needle 5, the puncture needle
The first check valve 6 is provided on 5, the pump housing 2 is sleeved on the bottleneck of culture bottle 1, and the bottle mouth position of the culture bottle 1 is provided with
Rubber stopper 13, the puncture needle 5 pass through rubber stopper 13, the blood sample being connected to inside culture bottle 1.
In addition, the culture bottle 1 is connected with the first elevating mechanism 14, the pump housing 2 is connected with the second elevating mechanism 15, this
In embodiment, concretely cylinder, the first elevating mechanism 11 can further connect for the first elevating mechanism 14 and the second elevating mechanism 15
Other transmission mechanisms are connect, realize automated exchanged cutter and the unloading of culture bottle 1, and can also be from detection mould group frame or place position
It taking out culture bottle 1 and is transported to designated position, the second elevating mechanism 12 of cooperation can realize that puncture needle 5 passes through rubber stopper 13 automatically,
Touch blood sample.
With further reference to Fig. 2, the downside of compression chamber 4 is provided with nozzle 7, is provided with second one-way valve 10 on the nozzle 7,
The plunger 3 be set to compression chamber 4 in and can moved axially back and forth with the space in extruding/expansion compression chamber 4 along compression chamber 4,
The rear end of the plunger 3 connects transmission mechanism 8, and transmission mechanism 8 is specially cylinder in the present embodiment, realizes that the front and back of plunger 3 is moved
It is dynamic.For blood sample by oozing out between plunger and compression chamber, the front end of plunger 3 is provided with seal head 9, the seal head in order to prevent
It is in sealing contact between 9 outer wall and the inner wall of compression chamber 4.
When transmission mechanism 8 drives plunger 3 to move backward, the space in compression chamber 4 is expanded, and makes in compression chamber 4
Lower relative to the pressure in culture bottle 1 at the vacuum of a part, blood sample enters compression by the inner hole of puncture needle 5
