Abstract
This application involves a kind of reagent bottles of anti-negative pressure of breathing freely, and when air pressure is greater than ambient pressure in bottle, air oppresses ventilative lip two sides naturally in bottle, and joint-cutting is firmly closed, prevents reagent from revealing.If reagent bottle inner and outer air pressure is identical, joint-cutting is also in closed state naturally, guarantee that reagent will not be revealed in transit, consider that limiting condition, that is, reagent bottle in transportational process is inverted, due to bottle sealing, ventilative lip is flooded by reagent, reagent itself has certain hydraulic pressure to ventilative lip two sides, it is closed joint-cutting, furthermore reagent will also overcome atmospheric pressure to flow out reagent bottle by joint-cutting.When using reagent, reagent needle is from sealing air-permeable member is worn out, and after drawing a certain amount of reagent extraction, by air hole, lip of breathing freely enters in bottle from joint-cutting, keep bottle inner and outer air pressure equal, to prevent the generation of bubble air.Therefore the reagent bottle of the anti-negative pressure of breathing freely of the utility model can prevent bubble from generating, and can play sealing anti-leak result well.
Description
Technical field
The application belongs to the field of medical instrument technology, more particularly, to a kind of reagent bottle of anti-negative pressure of breathing freely.
Background technique
In medical apparatus and instruments, reagent bottle is used to store up reagent (such as various luminous detection reagents) needed for testing
It deposits, transports and use.Require reagent bottle that there are good sealing characteristics, during transportation to prevent letting out in transportational process
Dew, when in use, reagent needle punctures the silicagel pad of reagent bottle to reagent, extracts reagent needle, reagent needle after drawing a certain amount of reagent
There are remaining reagent on the inside of silicagel pad when extraction, negative pressure is formed since reagent is reduced in reagent bottle at this time, outside air can be from
The punctured hole of silicagel pad enters in bottle, and bubble is thus generated on the inside of silicagel pad.
General reagent needle set has detecting liquid level function (using liquid level sensor), to determine amount of reagent in bottle, detects
Just start imbibition movement when reagent, imbibition in advance is prevented to be drawn onto air, thus guarantee the accuracy of addition reagent, above-mentioned bubble
In the presence of the mistake for directly resulting in detecting liquid level is visited, and when liquid level sensor detects bubble, liquid level sensor can be made to take for having connect
It contacts liquid level, begins to imbibition movement, this, which will lead to actually reagent needle, can not be drawn to reagent.

The annular grooves 33 with 22 cooperation of opening between platform 32, are provided with air hole 35, the lower circle on the upper rotary table 31
32 bottom of platform be provided with away from upper rotary table 31 direction extension ventilative lip 36, the ventilative lip 36 have joint-cutting 37 and with
The air hole 35 is connected to；
The diameter of the upper rotary table 31 is not small not less than the diameter of the lower rotary table 32 not less than the diameter of the opening 22
In the internal diameter of the bottle cap 20.
The reagent bottle of the anti-negative pressure of breathing freely of the present embodiment, when in use will sealing first with the elasticity of sealing air-permeable member 30
Air-permeable member 30 is pressed into the opening 22 of bottle cap 20, and then bottle cap 20 is spun on body 10, plays sealing function to bottleneck 11, is prevented
It only packs, the leakage of reagent in storage and transportational process.
In storage and transportational process, if air pressure is greater than ambient pressure in bottle, air oppresses ventilative 36 two sides of lip in bottle,
Joint-cutting 37 is firmly closed, prevents reagent from revealing.
If reagent bottle inner and outer air pressure is identical, there is certain thickness at joint-cutting 37, guarantees that reagent will not be let out in transit
Dew considers the limiting condition in transportational process --- reagent bottle is inverted, and due to bottle sealing, ventilative lip 36 is flooded by reagent, is tried
Agent itself has certain hydraulic pressure to ventilative 36 two sides of lip, is closed joint-cutting 37, furthermore reagent is to flow out reagent by joint-cutting 37
Bottle, will also overcome atmospheric pressure.
When using reagent, reagent needle is inhaled from sealing air-permeable member 30 (preferably passing through from the area's rotary table that punctures hereafter) is worn out
After taking a certain amount of reagent to extract, by air hole, lip 36 of breathing freely enters in bottle from joint-cutting 37, makes a bottle inner and outer air pressure phase air
Deng.
Further, the sealing air-permeable member 30 is silica gel material-medical silica-gel material.Silica gel material has good
Heat resistance, cold resistance, dielectricity, resistance to ozone and resistance to ag(e)ing, while there is elasticity well again, it can be in atmospheric pressure and reagent
Joint-cutting 37 is opened and closed under pressure well.
Further, there is funnel shaped vestibule, the joint-cutting 37 is located at ventilative 36 bottom of lip among the ventilative lip 36.
Funnel shaped vestibule can be convenient external air and enter in reagent bottle when needed, while ventilative lip 36 can be prevented to be not required to again
The region wanted is bonded and is closed channel.
Further, external screw thread 12 is provided at the bottleneck 11 at 10 top of body；Have inside the bottle cap 20 with outside
The internal screw thread 21 that screw thread 12 cooperates.Using being threadedly engaged, body 10 and bottle cap 20 can be made convenient for disassembly and assembly.
Further, the center of the upper rotary table 31 and lower rotary table 32 is recessed inwardly to form the more other regions of circular thickness
Thin punctures area's rotary table.The area's rotary table that punctures that thinner thickness is arranged can be convenient the movement of sampling probe, puncture sealing air-permeable member 30.
Preferably, the diameter of the lower rotary table 32 is also greater than the internal diameter of the bottleneck 11.After such setting, when by bottle cap 20
It being spun on body 10, air-permeable member 30 is sealed when screwing will bear against on the bottleneck 10 of body, and sealing function is played, prevents from packing,
The leakage of reagent in storage and transportational process.
The present embodiment can also increase the quantity of air hole 35 and ventilative lip 36 according to the size of reagent bottle.
Preferably, the reagent bottle of the anti-negative pressure of breathing freely of the present embodiment, the ventilative lip of the joint-cutting two sides with a thickness of 0.3~
0.5mm, such as 0.3mm, 0.4mm, 0.5mm.
It is enlightenment with the above-mentioned desirable embodiment according to the application, through the above description, relevant staff is complete
Full various changes and amendments can be carried out in the range of without departing from this item application technical idea.The technology of this item application
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
