Abstract
The utility model discloses a kind of pipettor suction nozzles, including suction nozzle end, have imbibition end face thereon, imbibition end face is provided with liquid sucting port；The suction nozzle end set has the first opening to be connected with liquid sucting port.First opening is obtained by suction nozzle end is cut off by the first section.A kind of pipettor suction nozzle involved by the utility model, in the liquid sucting port that imbibition end is made of end face opening and lateral opening so that when grumeleuse occurs in liquid, be not in the phenomenon that blocking liquid sucting port, so that experiment can be normally carried out, the time of experiment is saved, improves efficiency.
Description
Technical field
The utility model is related to pipettor technical field, especially a kind of pipettor suction nozzle.
Background technology
In medical treatment, drug, gene and protein research or blood analysis, it is often necessary to be set various using pipettor
Laboratory sample is manipulated in standby, it will be in the liquid sucking pipette of a certain amount of volume using pipettor.Needed in imbibition by
Suction nozzle stretches in liquid, if occur phenomena such as grumeleuse in liquid, it may appear that the phenomenon that liquid sucting port of suction nozzle is blocked, to reality
The operation tested impacts.
Invention content
The purpose of this utility model is to provide a kind of pipettor suction nozzle, can be when grumeleuse occurs in the liquid to be drawn
It can also normal extraction liquid so that experiment is normally carried out.
In order to solve the above technical problems, what the purpose of this utility model was realized in：
A kind of pipettor suction nozzle involved by the utility model, including suction nozzle end have imbibition end face, imbibition thereon
End face is provided with liquid sucting port；The suction nozzle end set has the first opening to be connected with liquid sucting port.
As a further illustration of the above scheme, first opening is that suction nozzle end cuts off gained by the first section
It arrives.
As a further illustration of the above scheme, the suction nozzle end further includes with the symmetrical setting in the first section
Two sections；The second section excision suction nozzle end forms the second opening.
As a further illustration of the above scheme, the intersection of first section and the second section and imbibition end face away from
From the diameter less than liquid sucting port.
The utility model has the beneficial effects that：A kind of pipettor suction nozzle involved by the utility model, imbibition end by
End face is open and the liquid sucting port of lateral opening composition so that is not in show what liquid sucting port blocked when grumeleuse occurs in liquid
As so that experiment can be normally carried out, and save the time of experiment, improve efficiency.
Description of the drawings
Fig. 1 is the dimensional structure diagram of embodiment；
Fig. 2 is the partial enlarged view of Fig. 1；
Fig. 3 is the front view of embodiment；
Fig. 4 is the partial enlarged view of Fig. 3；
Fig. 5 is the sectional view of Fig. 1.
Label is described as follows in figure：1- suction nozzles end；2- imbibitions end face；3- liquid sucting ports；4- first is open；5- second is opened
Mouthful；The first sections 6-；The second sections 7-.
Specific implementation mode
The utility model is further illustrated in the following with reference to the drawings and specific embodiments.
In conjunction with Fig. 1 to Fig. 5, elaborate to specific implementation mode.A kind of pipettor involved by the present embodiment is inhaled
Head, including suction nozzle end have imbibition end face thereon, and imbibition end face is provided with liquid sucting port；Suction nozzle end set has the first opening
It is connected with liquid sucting port.
Conventional pipettor is round with liquid sucting port of the suction nozzle set by imbibition end face.In use, especially
In carrying out standby blood analysis, it is possible to will appear grumeleuse when drawing blood, in blood, may making round imbibition
Mouth causes blockages.To enable normally being drawn to blood, the first opening of setting in the side of liquid sucting port, in imbibition
When mouth causes blockages, blood enters in being open from first set by side inside suction nozzle.
In the present embodiment, the first opening is obtained by suction nozzle end is cut off by the first section.First section and end face at
The angle of setting.Suction nozzle end is a conical pipe with liquid sucting port, and the first section can form first when cutting off suction nozzle end and open
Mouthful, the shape of the first opening is a curve, parabolically shape.
In order to further achieve the effect that imbibition, suction nozzle end further include being cut with the second of the symmetrical setting in the first section
Face.Second section cuts off suction nozzle end and forms the second opening.Second opening shape with first opening shape it is identical, respectively to
Opposite direction tilts.
First section and the second section are respectively provided with intersection with imbibition end face, and the distance of two intersections is less than the straight of liquid sucting port
Diameter.
The connecting pin of the suction nozzle of pipettor involved by the utility model and pipettor may be designed to required shape, be suitable for
Various pipettors.
Embodiment one
In conjunction with Fig. 1 to Fig. 5, elaborate to the present embodiment.In the present embodiment, a diameter of 0.5mm of liquid sucting port, two
The distance of intersection is 0.2-0.4mm, is 0.35mm in the present embodiment.The angle of first section and the second section is ranging from
18-20 °, be 19 ° selected by the present embodiment.The distance of the vertex distance imbibition end face of opening is 0.4-1.0mm, the present embodiment
In be 0.6mm.First section, the second section vertex be 3-6mm at a distance from imbibition end face, be 3.5mm in the present embodiment.
Embodiment two
In the present embodiment, a diameter of 0.5mm of liquid sucting port, the distances of two intersections are 0.2-0.4mm, in the present embodiment
For 0.2mm.Ranging from 18-20 ° of the angle of first section and the second section is 18 ° selected by the present embodiment.The top of opening
Distance of the point apart from imbibition end face is 0.4mm, is 0.6mm in the present embodiment.First section, the vertex of the second section and imbibition end
The distance in face is 3-6mm, is 3mm in the present embodiment.
