The utility model also can be achieved through the following technical solutions: above-mentioned cup is provided with inlet, liquid outlet, air inlet, middlely links to each other with feed tube with the umbrella post that stretches through in centrifugal tank body, and a space that can hold the revolution rotation is arranged in cup, the ring-like hydrops groove in one or two garden is formed at this bottom, space.Above-mentioned cup top, revolution top corresponding position has a buffering ring, and this buffering ring and cup are one-body molded.
The structure of above-mentioned revolution can adopt an end to link to each other with the shell of centrifugal tank body, the other end be one upwards, outwards after the upset, downward again rotary body; Also can adopt the structure of other form as revolution.
The utility model has the advantages that: after taking the liquid sealing; the jar outer air can not enter in the tophan box liquid that has purified is polluted; and through the effect of two ring-like hydrops grooves in garden and the effect of buffering ring; can protect blood cell not crashed, air can not enter, so improved the degree of purity of blood; improved product quality; the health that helps human body is not again owing to there being wear-out part, so improved the service life of product.
The utility model further specifies by the following drawings and embodiment.
Fig. 1, be prior art structure cutaway view.
Fig. 2, be the structure cutaway view of the utility model embodiment ().
Fig. 3, be the structure cutaway view of the utility model embodiment (two).
Fig. 4, be the structure cutaway view of the utility model embodiment (three)
Referring to Fig. 2, be the structure cutaway view of the utility model embodiment (), it is an a kind of liquid sealing tophan box, mainly comprises the centrifugal tank body 1 of rotation and places the cup 2 of centrifugal tank body 1 upper stationary to constitute; In cup 2, be provided with a hydrops groove 25 that is used for the liquid sealing; Between centrifugal tank body 1 and cup 2, also be provided with and link to each other with centrifugal tank body 1, and the revolution 5 of synchronous rotation, one end of this revolution 5 links to each other with the shell 11 of centrifugal tank body 1, the other end be one upwards, outwards after the upset, downward again rotary body, its port of export is immersed in the hydrops groove 25 of cup 2, forms the liquid sealing.
Above-mentioned cup 2 is provided with inlet 21, liquid outlet 22, air inlet 23, and the centre links to each other with feed tube 4 with the umbrella post 3 that stretches through in centrifugal tank body 1; Its inlet 21 and liquid outlet 22, air inlet 23 not on same vertical plane (convenient for statement, each figure of this case all is drawn on the same vertical plane).A space 24 that can hold revolution 5 rotations is arranged in the above-mentioned cup 2, and the ring-like hydrops groove 25 in a garden is formed at these 24 bottoms, space, and the portion that is held of this cup 2 between two planes 26,27 on the cup 2, is used for fixing cup 2.
Above-mentioned umbrella post 3, feed tube 4, the cup 2 that stretches through in centrifugal tank body 1 formed one, be static, suspension (among the figure shown in the dash area), and and the rotating part formed by centrifugal tank body 1, revolution 5 between have bigger gap, between can not produce friction, there is not consumable accessory, so can improve the life-span of product; Stationary part is suspended in the middle of the rotating part in addition, and stationary part and rotating part be not when being held, and relative position has the very big free degree and can contact between them.
During work; The bottom of centrifugal tank body 1 is fixed on the centrifuge, and stationary part clamp arm clamping, the clamp arm termination is clamped in (not shown) on 26,27, by injecting harmless liquid in the air inlet 23 vector product liquid baths 25, sealing in advance, then process seal spare 7 is removed (because of its effect is: when not working) in case a jar outer air enters in the centrifugal tank body 1.Blood enters in the centrifugal tank body 1 from flow through umbrella post 3, feed tube 4 of inlet 21, and after being full of centrifugal tank body 1, from inlet 21 input cleaning fluids, cleaning fluid flows through blood, takes away impurity such as smudge cells, anti-coagulants, discharges from liquid outlet 22; When the air in jar need replenish, can inject clean harmless gas from air inlet 23, to satisfy the requirement of technology.
Referring to Fig. 3, be the structure cutaway view of the utility model embodiment (two), its general structure and operation principle are basic identical with embodiment ().Difference is: embodiment () is held the bottom that position 26,27 is positioned at cup 2, in case air enters in the centrifugal tank body 1; Embodiment (two) is held the top that position 26,27 is positioned at cup 2, in addition, and the height among the aspect ratio embodiment (two) of the revolution 5 among the embodiment ().
Referring to Fig. 4, be the structure cutaway view of the utility model embodiment (three), its general structure and operation principle are basic identical with embodiment () (two), difference is:
A space 24 that can hold revolution 5 rotations is arranged in the 1. above-mentioned cup 2, and two ring- like hydrops grooves 25,29 in garden are formed at these 24 bottoms, space.Wherein inner product liquid bath 25 is used for the liquid sealing, and apposition liquid bath 29 is used for fluid.
2. above-mentioned cup 2 tops, revolution 5 top corresponding positions have a buffering ring 28, and this buffering ring 28 is one-body molded with cup 2.Make since the centrifugal liquid that throws away directly with cup 2 rigid contacts, and with the liquid that throws away previously as buffer solution, reach and reduce the purpose of damaging blood cell.
3. on the structure of revolution 5, adopt an end to link to each other with the shell 11 of centrifugal tank body, the other end be one upwards, outwards inwardly indentation again after the upset, and downward rotary body.When the liquid of liquid outlet 22 outflows still need use, can not carry out gas barrier with the liquid that flows out, and need to inject harmless liquids, the gas barrier that tophan box is inside and outside in the hydrops groove 29 outside.Be that centrifugal tank body 1 interior air enters in the hydrops groove 25 through revolution 5 inwalls along the direction of arrow; the blood that has purified simultaneously is injected in the buffering ring 28 along revolution 5; cushion by residual liquid in its buffering ring 28, do not crashed, fall into then in the apposition liquid bath 29 with the protection blood cell.Here inner product liquid bath 25 is used for air seal, and apposition liquid bath 29 is used to collect the liquid of outflow, leads to liquid outlet 22 then, finishes its technical process.
