212D ends) compared with the close centrifugation of the first miniflow hole 216A, the second miniflow hole 216B, the 3rd miniflow hole 216C and the 4th miniflow hole 216D
The mode of the axis of rotation of machine, centrifuge tube external member group 300 is entirely put into centrifuge.In this way, four kinds of reagents 222,
224th, 226 it will flow into the cuvette groove 314 of test tubes 310 from body 210 during centrifuge operates with 228 and contact
A corpse or other object for laboratory examination and chemical testing.Thus, the centrifuge tube external member 200 of the present embodiment and centrifuge tube external member group 300, which can be applicable to, needs four kinds of reagents
Inspection in.Moreover, because the first liquid bath 214A, the second liquid bath 214B, the 3rd liquid bath 214C and the 4th liquid bath 214D are indivedual
Independent, so needing not worry about four kinds of reagents 222,224,226 and 228 can be pre-mixed and go bad.
The present embodiment is by taking four liquid bath 214A-214D and four kinds of reagents 222,224,226 and 228 as an example, certainly at it
Also the quantity of liquid bath and reagent can be increased and decreased in his embodiment according to demand.In the present embodiment, the first miniflow hole 216A aperture with
Second miniflow hole 216B aperture is identical, and the first miniflow hole 216A aperture is more than the 3rd miniflow hole 216C aperture, and the 3rd
Miniflow hole 216C aperture is identical with the 4th miniflow hole 216D aperture.Certainly, the first miniflow hole 216A aperture, the second miniflow
Hole 216B aperture, the 3rd miniflow hole 216C aperture and the 4th miniflow hole 216D aperture can also be all identical or all not
Together.Get over hour in the aperture in miniflow hole, it is possible to provide bigger pore power, therefore the reagent in liquid bath may require that and turn in bigger
The bigger centrifugal force of the lower acquisition of speed could pass through miniflow hole.By the aperture in the miniflow hole for controlling different liquid baths, it is possible to allow not
A corpse or other object for laboratory examination and chemical testing is contacted by miniflow hole in different rotating speeds with the reagent in liquid bath, and then reaches and difference sequentially is utilized to a same corpse or other object for laboratory examination and chemical testing
The purpose that reagent is tested, it is not necessary to manually add different reagents successively.In the present embodiment, the first miniflow hole 216A hole
Footpath and the second miniflow hole 216B aperture are 0.6 mm, and the 3rd miniflow hole 216C aperture and the 4th miniflow hole 216D aperture
For 0.3 mm.The aperture in miniflow hole can for example change in 0.1 mm to work between 0.7 mm, but the present invention is not limited to this.
In addition, in the present embodiment, the first liquid bath 214A, the second liquid bath 214B and the 3rd liquid bath 214C cell body length all phases
Deng, and the first liquid bath 214A cell body length is more than the 4th liquid bath 214D cell body length.Specifically, the first miniflow hole 216A
(the i.e. second opening at the top of distance, the second miniflow hole 216B to body 210 to the top of body 210 (the i.e. first opening 212A)
Distance and the second miniflow hole 216B to the top of body 210 (the i.e. the 3rd opening 212C) distance 212B) is identical, but first is micro-
Distance at the top of discharge orifice 216A to body 210 is more than the 4th miniflow hole 216D to the top of body 210 (the i.e. the 4th opening 212D)
Distance.Certainly, the first miniflow hole 216A, the second miniflow hole 216B, the 3rd miniflow hole 216C and the 4th miniflow hole 216D be respectively extremely
The distance at the top of body 210 can also all identical, part it is identical or all different.When centrifuge tube external member group 300 is put into
When in centrifuge, the top of body 210 is compared with the first miniflow hole 216A, the second miniflow hole 216B, the 3rd miniflow hole 216C and the 4th
Axis of rotation of the miniflow hole 216D close to centrifuge.Therefore, the first miniflow hole 216A to the axis of rotation of centrifuge distance
The 4th miniflow hole 216D can be more than to the distance of the axis of rotation of centrifuge.When the distance of the axis of rotation in miniflow hole to centrifuge
More hour, reagent may require that bigger rotating speed could obtain bigger centrifugal force and by miniflow hole.By controlling different liquid baths
The distance of axis of rotation of the middle miniflow hole to centrifuge, it is possible to which the reagent allowed in different liquid baths passes through miniflow in different rotating speeds
Hole flows out in test tubes 310 and contacts a corpse or other object for laboratory examination and chemical testing, and then reaches sequentially a same corpse or other object for laboratory examination and chemical testing is tested using different reagents
Purpose, it is not necessary to manually add different reagents successively.In the present embodiment, due to cell body length and the micro- orifice aperture of liquid bath
Change design, cause in practical operation, under slow-speed of revolution centrifuge operation situation, in the first liquid bath 214A and the second liquid bath
The first reagent 222 and the second reagent 224 in 214B can be simultaneously first respectively from the first miniflow hole 216A and the second miniflow hole 216B
Flow out in test tubes 310 and reacted with a corpse or other object for laboratory examination and chemical testing to be measured.Then under middle speed centrifuge operation situation, due to the 3rd miniflow hole
216C aperture is less than the first miniflow hole 216A and the second miniflow hole 216B, and the 3rd miniflow hole 216C is to the rotary shaft of centrifuge
The distance of the heart is more than the 4th miniflow hole 216D, therefore the 3rd reagent 226 can be flowed out in test tubes 310 in the middle rotating speed stage.
Because the 4th miniflow hole 216D aperture it is small, and the 4th miniflow hole 216D to centrifuge axis of rotation it is closer to the distance, therefore
The 4th reagent 228 in 4th liquid bath 214D can be just expelled in test tubes 310 by high speed centrifuge phase run.When
So, the aperture in miniflow hole and miniflow hole to the distance of the axis of rotation of centrifuge can arrange in pairs or groups change, without limiting to only both changes
One of them.
