Abstract
The utility model discloses a kind of New test tube lid, the top in enclosing cover (1) is provided with interior plug (3), and the circumferential direction along enclosing cover (1) inwall is provided with the rubber salient point (2) of more than 2 equably.Test tube cap of the present utility model can be stuck on test tube outer wall by rubber salient point, and interior plug can be selected to fill in or do not fill in test tube as required, therefore test tube cap of the present utility model can as test tube plug, again can as dw, and all operations only needs one hand to complete, the requirement of supplementary reproduction experiment can be met preferably.
Description
Technical field
The utility model relates to a kind of New test tube lid, belongs to medical experiment equipment technical field.
Background technology
The most frequently used reagent in supplementary reproduction laboratory has two kinds, and one is ovum nutrient solution, and another kind is embryo medium, and the two all need spend the night in incubator inner equilibrium before use.Owing to not containing buffer composition in ovum nutrient solution, when balancing in incubator, need the test tube sealing that ovum nutrient solution will be housed, otherwise the CO in incubator
2gas can change the potential of hydrogen of ovum nutrient solution; And embryo medium needs and CO in incubator before using
2gas carries out gaseous interchange, and the test tube that thus embryo medium is housed is in open state.Traditional way is: the test tube jam-pack of ovum nutrient solution will be housed with test tube plug, and the test tube plug that embryo medium is housed is opened.But, above-mentioned way has following deficiency: 1. need both hands to operate when being extracted by the test tube plug of jam-pack simultaneously, however operator's normally hand-held test tube, the hand-held pipettor of another, therefore operator cannot vacate both hands and complete above-mentioned action, make troubles to operator; 2. the test tube of embryo medium is housed owing to not having test tube plug, the dust in incubator or impurity can fall into embryo medium, pollute.
Utility model content
The purpose of this utility model is, provide a kind of structure simple, be convenient to one-handed performance, can as test tube plug, again can as the New test tube lid of dw, to overcome prior art deficiency.
The technical solution of the utility model: a kind of New test tube lid, the top in enclosing cover is provided with interior plug, and the circumferential direction along enclosing cover inwall is provided with the rubber salient point of more than 2 equably.
Further, aforesaid rubber salient point is arranged on below enclosing cover inwall.
Further, aforesaid rubber salient point is hemispherical dome structure.
Owing to adopting technique scheme, the utility model has the advantage of: when adopting the utility model to carry out supplementary reproduction experiment, before incubator put into by the test tube that ovum nutrient solution is housed, only need enclosing cover be enclosed within above test tube, thumb is pressing a little firmly, and interior plug namely can by the oral area jam-pack of test tube, when opening, only a little firmly up need push up the bottom of enclosing cover with thumb, enclosing cover can be opened together with interior plug.And before incubator put into by the test tube that embryo medium is housed, only enclosing cover need be enclosed within above test tube gently, rubber salient point below enclosing cover inwall will be stuck on test tube outer wall, and interior plug can not be filled in test tube, because between rubber salient point, gap is larger, air can enter in test tube along this gap, makes the CO in embryo medium and incubator
2gas fully exchanges, and turn avoid dust in cultivation and impurity falls in incubator simultaneously.Therefore, not only structure is simple, cost of manufacture is low for the utility model, can as test tube plug, again can as dw, and all operations only needs one hand to complete, and can meet the requirement of supplementary reproduction experiment preferably.
Accompanying drawing explanation
Fig. 1 is embodiment 1 structural representation in the utility model;
Fig. 2 is embodiment 2 structural representation in the utility model.
Description of reference numerals: 1-enclosing cover, 2-rubber salient point, plug in 3-.
Embodiment
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figures 1 and 2, the top in enclosing cover 1 is provided with interior plug 3 to the structural representation of New test tube lid, is provided with 3 rubber salient points 2 equably along the circumferential direction below enclosing cover 1 inwall, and described rubber salient point 2 is hemispherical dome structure.
Embodiment 1
See Fig. 1, when adopting the utility model to carry out supplementary reproduction experiment, before incubator put into by the test tube 4 that embryo medium is housed, only need enclosing cover 1 be enclosed within above test tube 4 gently, rubber salient point 2 below enclosing cover 1 inwall will be stuck on test tube 4 outer wall, and interior plug 3 can not be filled in test tube 4, because gap between rubber salient point 2 is larger, air can enter in test tube 4 along this gap, makes the CO in embryo medium and incubator
2gas fully exchanges, and turn avoid dust in cultivation and impurity falls in incubator simultaneously.
Embodiment 2
See Fig. 2, when adopting the utility model to carry out supplementary reproduction experiment, before incubator put into by the test tube 4 that ovum nutrient solution is housed, only need enclosing cover 1 be enclosed within above test tube 4, thumb is pressing enclosing cover 1 a little firmly, and interior plug 3 namely can by the oral area jam-pack of test tube 4, when opening, only a little firmly up need push up the bottom of enclosing cover 1 with thumb, enclosing cover 1 can be opened together with interior plug 3.
Claims (3)
1. a New test tube lid, is characterized in that: the top in enclosing cover (1) is provided with interior plug (3), and the circumferential direction along enclosing cover (1) inwall is provided with the rubber salient point (2) of more than 2 equably.
2. New test tube lid according to claim 1, is characterized in that: described rubber salient point (2) is arranged on below enclosing cover (1) inwall.
