Description

Babbitt suction pipe capable of being lengthened and bent

Technical Field

The utility model relates to the technical field of liquid measurement, in particular to a Pasteur pipette capable of being lengthened and bent.

Background

In the field of biomedical science, it is currently necessary to transfer a liquid sample using an auxiliary tool, i.e. to transfer the sample there to, the more common of such auxiliary tools being a papanicolaou pipette. Conventional disposable pasteur pipettes are all made of polyethylene or polypropylene material with a circular pouch behind them. However, the existing Pasteur pipette has the following defects: 1) The length is shorter, and liquid at the bottom of the deeper container cannot be sucked; 2) Cannot be bent, and cannot suck liquid at the corners of the container when the bottom of the container is small or the shape of the container is irregular.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, and provides the Pasteur pipette which can be lengthened and bent properly, can absorb liquid at the deeper bottom, is suitable for containers with different shapes, and reduces medicine waste.

In order to achieve the above purpose, the utility model provides an elongated and bendable papanicolaou suction pipe, comprising a suction pipe and a suction bag with scale areas, wherein an elongated and bent structure is arranged between the suction pipe and the suction bag, the elongated and bent structure comprises bending rings which are arranged at intervals in the axial direction of the suction pipe, the bending rings are connected through telescopic parts, the adjacent bending rings are respectively a convex part and a concave part, the diameter of the bending ring of the convex part is larger than the outer diameter of the suction pipe, and the diameter of the bending ring of the concave part is smaller than the inner diameter of the suction pipe.

Further, the capacity of the pipette is 3ml.

Further, the pipette has a capacity of 5ml.

Further, the Pasteur pipette is integrally formed from a polypropylene material.

The utility model has the following beneficial effects:

1) The utility model adds an elongated bending structure based on the existing Pasteur pipette.

2) The pasteur pipette may be suitably elongated to draw liquid into the bottom of a deeper container.

3) The present pasteur pipette may be suitably curved to draw liquid into the corners of a small-bottomed large or irregularly shaped container.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.

As shown in fig. 1 to 3, an elongated flexible pasteur pipette of the present utility model comprises a head pipette 1, a graduated flask 2, an elongated flexible structure 3 and a pouch 6.

In particular, the elongated curved structure 3 is arranged between the graduated flask 2 and the suction bladder 6. The elongated bending structure 3 comprises bending rings 4 and telescopic parts 5, wherein the bending rings 4 are arranged at intervals in the axial direction of the suction tube, and the bending rings 4 are connected through the telescopic parts 5. Adjacent bend rings 4 are convex and concave, respectively, wherein the diameter of the bend ring of the convex is larger than the outer diameter of the straw and the diameter of the bend ring of the concave is smaller than the inner diameter of the straw. The plurality of bending rings 4 may be folded by the expansion and contraction part 5 and may be elongated appropriately, and the bending rings 4 may be bent appropriately to different angles due to the convex and concave portions of the adjacent bending rings 4.

In one embodiment, the pasteur pipette is integrally formed from a polypropylene material.

In one embodiment, the capacity of the pasteur pipette of the present utility model is 3ml, and in other embodiments, the capacity of the pasteur pipette is 5ml.

In one embodiment, the length of the pasteur pipette with a capacity of 3ml is 200mm, wherein the length of the sachet 6 is 40mm, the length of the elongated curved structure 3 is 50mm, the length of the intermediate graduation area 2 is 60mm, and the length of the head pipette 1 is 50mm.

In the above embodiment, the diameter of the suction bag 6 is 15mm, the diameter of the scale area 2 is 6mm, and the diameter of the head suction tube 1 is 3mm. The elongated curved structure has 25 turns 4 with a convex turn 4 diameter of 7mm and a concave turn 4 diameter of 5mm.

In the actual use process, the operation of elongating the Pasteur pipette is as follows: the suction bag part of the hand-held Pasteur pipette and the middle scale area of the hand-held Pasteur pipette are gently pulled apart by the folding bending ring, so that the Pasteur pipette can be effectively lengthened. The operation of bending the papanicolaou pipette is as follows: one hand holds the suction bag part of the Pasteur pipette and the other hand holds the middle scale area of the Pasteur pipette, and the bending ring part is slightly bent, so that the Pasteur pipette can be effectively bent.

While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
