Abstract
The utility model discloses a kind of dual-purpose minim pipettes, including air bag and capillary communicated with the airbag, the air bag and capillary are integrally formed by blow molding, there is at least one stomata on the air bag, it blocks stomata and squeezes out the liquid in capillary by pressuring gasbag, the capillary passes through the stomata and air communication on air bag, capillary tube inner wall hydrophilic treated makes it have self-suction function, the connecting portion of the air bag and capillary is variable-diameter structure, the diameter of section of the air bag is greater than the upper end cross-section diameter of capillary, the diameter of its cross section of hair follicle and the connecting portion of capillary becomes larger siphonage is made to disappear suddenly.By the above-mentioned means, the dual-purpose minim pipette of the utility model, structure is simple, easy to operate, can one pipe it is dual-purpose, significantly reduce use cost.
Description
Technical field
The utility model relates to field of medical products, more particularly to a kind of dual-purpose minim pipette.
Background technique
Micro blood-taking tube is the common tool of the medical departments such as hospital, inspection center acquisition blood, this micro blood-taking tube
, both ends open smaller by the internal diameter and glass tube of connection is made, by one end of micro blood-taking tube and blood to be collected when acquiring blood
Liquid contact, using capillary theory, makes blood to be collected automatically into micro blood-taking tube inside, then plugs a silica gel and inhales
Capsule, squeezes to inhale capsule and be expressed into a kind of solution blood and mixes；It is subsequent usually also to need a common suction pipe, draw a small amount of mix
Drop is closed to be detected into test board.
Summary of the invention
The utility model is mainly solving the technical problems that provide a kind of dual-purpose minim pipette, and structure is simple, easy to operate, energy
Enough pipes are dual-purpose, significantly reduce use cost.
In order to solve the above technical problems, the technical solution that the utility model uses is: a kind of dual-purpose minim pipette is provided,
Including air bag and capillary communicated with the airbag, the air bag and capillary are integrally formed by blow molding, on the air bag
With at least one stomata, blocks stomata and squeeze out the liquid in capillary by pressuring gasbag, the capillary passes through air bag
On stomata and air communication, capillary tube inner wall hydrophilic treated so that it is had self-suction function, the connection of the air bag and capillary
Position is variable-diameter structure, and the diameter of section of the air bag is greater than the upper end cross-section diameter of capillary, the connection of hair follicle and capillary
The diameter of its cross section of position becomes larger siphonage is made to disappear suddenly.
In one preferred embodiment of the utility model, the quantity of the stomata is 2, and stomata is located among air bag directly
Diameter maximum.
In one preferred embodiment of the utility model, the capillary length to determine maximum imbibition volume, or
There is the graduation mark of mark volume on capillary described in person.
In one preferred embodiment of the utility model, the air bag is ellipticity.
In one preferred embodiment of the utility model, the capillary is the capillary that handles by hydrophily with automatic
Draw liquid.
The beneficial effects of the utility model are: the dual-purpose minim pipette of the utility model, structure is simple, easy to operate, Neng Gouyi
Manage dual-purpose, significant decrease use cost.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is the structural schematic diagram of one preferred embodiment of the utility model；
The components in the drawings are labeled as follows: 1, air bag, 2, capillary, 3, stomata, 4, variable-diameter structure.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to Fig. 1, a kind of dual-purpose minim pipette, including air bag 1 and the capillary being connected with air bag 12,1 He of air bag
Capillary 2 is integrally formed by blow molding, has at least one stomata 3 on air bag 1, blocks stomata 3 and by pressuring gasbag 1 by capillary
Liquid in pipe 2 squeezes out, and capillary 2 makes it have self-suction function, air bag 1 and hair by the stomata 3 on air bag 1 with air communication
The connecting portion of tubule 2 is variable-diameter structure 4, and the diameter of section of air bag 1 is greater than the upper end cross-section diameter of capillary 2, hair follicle 1 and hair
The diameter of its cross section of the connecting portion of tubule 2 becomes larger siphonage is made to disappear suddenly.
In addition, 3 quantity of stomata are 2, and stomata 3 is located at air bag mid diameter maximum.
In addition, 2 length of capillary is to determine the quarter on maximum imbibition volume or capillary 2 with mark volume
Spend line.
In addition, air bag 1 is ellipticity.
In addition, capillary 2 is by capillary that hydrophily is handled with automatic sucking liquid.
The dual-purpose minim pipette of the utility model when drawing micro liquid (usual 50 microlitres or less) is not blocked stomata inclination and is connect
Liquid is touched, so that capillary is filled liquid using siphon principle, blocks stomata with finger and will be micro- in capillary by pressuring gasbag
Quantity of fluid squeezes out；When drawing 50 microlitres or more liquid, stomata is blocked by pressuring gasbag with finger, is inserted into liquid and gently unclamps finger
But still stomata is blocked, more liquid can be drawn using the elastic recoil of air bag, then block stomata with finger and press
Air bag squeezes out liquid, realizes that a pipe is dual-purpose.It is different from the prior art, the dual-purpose minim pipette of the utility model, structure is simple, operation
It is convenient, can a pipe it is dual-purpose, significantly reduce use cost.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
