Description
Technical field
The utility model is related to biobattery sensor technical fields, and in particular to a kind of cut-off for biosensor
Device.
Background technology
Cross-cutting exploration and combination is also constantly unfolded in feeler with the sustainable development of electronics technology, application.Wherein,
In fast-developing biology or medical science and technology field, the appearance of biosensor is not less than being the one big of modern age biology relevant technical
It breaks through.Biosensor is commonly defined as：Through the biomolecule combination energy converter or biochip of immobilization, to detect biology
The chemical substance or biomolecule of in vitro or play in vivo or therewith a kind of device that response is generated after specific reciprocation.
Biosensor meets the demand of many important measurements, especially in drug, metabolism and the intermolecular friendship of other biological
In the measurement of interaction.Although traditional analysis instrument can also achieve the purpose that similar, the most unique place of biosensor
The high sensitivity that exactly has with biomolecule thereon from biological sensing component, high specific or highly selective, and in fact
When the characteristic that detects.Its reason is that organism inherently has miscellaneous chemocepter, in other words, organism itself
The aggregate of actually one chemoreceptor, these chemoreceptors all have specificity or selectivity and the sensitivity of height.
With the gradual maturation of biosensor technology, the biosensor of more and more and assorted form also lists one after another.Wherein, it ties
The biosensor for closing optics mechanism is even more to having greatly application latent on protein or nucleic acid or the detection of other biological chemical molecular
Power.
On the other hand, through artificial or mechanically actuated needed for conventional biochemical is analyzed, with micro- side Pu, micro-valve door, micro-
The microfluid components such as filter, micro-mixer, microchannel, microsensor and microreactor concentration is made on microfluidic device,
To carry out the programs such as sample pre-treatments, mixing, transmission, separation and detecting, even more it is actively used on biosensor.Its
Application field can cover such as new drug development, biology and medicine research, or it is strong examine, the detection of disease detection, pathogenic infection, blood
The clinical examinations such as screening, even such as national defense and military detecting, legal medical expert recognize identification, environment and Food Inspection non-medical applications neck
Domain.
Biosensor liquid feeding process, battery liquid inject battery compartment through bottom liquid inlet mouth, and gas is logical in battery compartment
Top gas outlet is crossed to naturally drain.Stopper starts after liquid is full of battery compartment, blocks battery compartment and import and goes out
Mouth piping connection makes the battery liquid storage battery cavity of biosensor form separate space, it is therefore desirable to block battery cavities
The stopper of body and inlet and outlet pipeline.
Utility model content
To be solved in the utility model is the deficiencies in the prior art, and it is an object of the present invention to provide a kind of being used for biosensor
Stopper.
The utility model is achieved through the following technical solutions：
A kind of stopper for biosensor, including support unit and cut-off unit, the support unit are one
The hollow hemispherical shell of end opening, cut-off unit are cylinder, and cut-off unit is located at the inside of support unit, ends unit
Diameter is less than the diameter of support unit, and the top for ending one end of unit and the inner wall of support unit connects, and ends the another of unit
One end is hanging, and support unit is elastic material.
Preferred embodiment, the support unit and cut-off unit are integrally formed for rubber material.
Preferred embodiment, the support unit outer wall are equipped with fixed cell, and the fixed cell is annular protrusion, fixed cell
The centerline parallel of center line and support unit.
The longitudinal cross-section of preferred embodiment, the fixed cell is rectangle.
The utility model compared with prior art, has the following advantages and advantages：The biology of the utility model passes
Sensor stopper, using integrally formed rubber material, the stopper of rubber material has good elasticity and leakproofness
Can, biosensor needs replacing liquid after the completion of test, closes stopper, and battery compartment joins with inlet and outlet pipeline
It is logical, it first passes through special gas and purges waste liq, then filled by pipeline and cultivate liquid cleaning battery compartment, cleaning is repeated several times
Afterwards, cultivation liquid is filled, starts stopper, blocks battery compartment and connect with inlet and outlet pipeline.
