Abstract

The utility model discloses a dipping type pasteur sucker, which comprises a bubble sucking section, a pipe body section, an inclined mouth sucker and sponge; the bubble absorbing section is arranged at the upper end of the pipe body section; the inclined nozzle is arranged at the lower end of the pipe body section; the total length of the bevel-opening suction nozzle is about 0.5 cm; the sponge is arranged at the position of the inclined-mouth suction nozzle end which is 2-3cm upward from the pipe body section; the material of the bubble suction section, the pipe body section and the inclined-opening suction nozzle is transparent high polymer material polyethylene. The utility model discloses an useful part lies in: the sponge has stronger water absorption performance, and a small amount of spread liquid can be absorbed in a dipping and sucking mode; the suction nozzle of bevel connection is parallel with the liquid level, can submerge whole suction nozzle under the liquid level, conveniently absorbs, can stay the tissue in the blake bottle simultaneously, needn't rock the blake bottle, can not influence the adherent growth of tissue, can not cause the tissue extravagant.

Description

Dipping type pasteur straw

Technical Field

The utility model relates to a straw, concretely relates to dip in and inhale formula pasteur straw belongs to liquid and moves and get technical field.

Background

The pasteur pipette is a disposable consumable product in a laboratory, is widely applied to the fields of heredity, medicine, epidemic prevention, clinic, heredity, biochemistry, petrifaction, military affairs and the like, and is mainly applied to the operations of sucking, transferring or carrying a small amount of liquid, such as cell tests, clinical tests, clone tests and the like.

The existing Pasteur straw is divided into three sections, namely a soft bubble suction section, a liquid storage pipe body section and a liquid taking suction nozzle, wherein the suction nozzle is a flat opening, and for a small amount of tiled liquid, the opening of the suction nozzle cannot be completely immersed below the liquid level and is difficult to absorb; when the liquid is changed, a pasteur pipette or a pipette is adopted to easily suck out the culture medium stock solution and the tissue together, so that the tissue falls off and the adherent growth of the tissue is influenced; meanwhile, tissues are sucked out of the culture bottle by the flat-mouth suction nozzle or the suction nozzle is blocked by larger tissue money, so that the wall attachment of the tissues and the waste of the tissues or the inconvenience of liquid taking are influenced; even if the aspirated tissue is added back to the culture flask, some tissue is lost outside the culture flask, and eventually, an insufficient amount of cells or even no cells grow out.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model aims to provide a dipping type pasteur sucker.

In order to achieve the above object, the utility model adopts the following technical scheme:

a dip-suction type Pasteur sucker comprises a bubble suction section, a pipe body section, an inclined-opening suction nozzle and a sponge; the bubble absorbing section is arranged at the upper end of the pipe body section; the inclined nozzle is arranged at the lower end of the pipe body section; the total length of the bevel-opening suction nozzle is about 0.5 cm; the sponge is arranged at the position of the inclined-mouth suction nozzle end which is 2-3cm upward from the pipe body section.

Preferably, the material of the bubble suction section, the pipe body section and the inclined-opening suction nozzle is transparent high polymer material polyethylene.

The utility model discloses an useful part lies in:

the sponge has stronger water absorption performance, and a small amount of spread liquid can be absorbed in a dipping and sucking mode; the suction nozzle of bevel connection is parallel with the liquid level, can submerge whole suction nozzle under the liquid level, conveniently absorbs, can stay the tissue in the blake bottle simultaneously, needn't rock the blake bottle, can not influence the adherent growth of tissue, can not cause the tissue extravagant.

Drawings

FIG. 1 is a schematic diagram of a dip-type Pasteur pipette according to an embodiment of the present invention;

the meanings indicated in the figures are: 1-a bubble absorbing section, 2-a pipe body section, 3-an inclined opening suction nozzle and 4-sponge.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

A dip-suction type Pasteur sucker comprises a bubble suction section 1, a pipe body section 2, an inclined-opening suction nozzle 3 and a sponge 4; the bubble absorbing section 1 is arranged at the upper end of the pipe body section 2; the bevel connection suction nozzle 3 is arranged at the lower end of the pipe body section 2; the total length of the bevel-mouth suction nozzle 3 is about 0.5 cm; the sponge 4 is arranged at the position 2-3cm upwards from the end of the bevel-mouth suction nozzle 3 to the pipe body section 2. The material of the bubble absorbing section 1, the pipe body section 2 and the inclined nozzle 3 is transparent high polymer material polyethylene.

When in use, the bubble sucking section 1 of the dip-type pasteur pipette is pinched by fingers, the surface of the inclined-mouth suction nozzle 3 is tightly attached to liquid to be sucked, the fingers are loosened, and the liquid is sucked by pressure and the suction capacity of the sponge 4; for a very small amount of liquid, the bubble section 1 does not need to be pinched and sucked, the liquid can be sucked out only by the way that the sponge 4 dips the liquid, meanwhile, the sponge 4 can prevent the tissue from being sucked into the tube section 2, even if only a small amount of liquid exists, the liquid can be easily and completely taken out by the way of dipping and sucking, and the tissue can be guaranteed not to move. After being taken out, the bubble absorbing section 1 is pinched again by fingers, and then the liquid can be added into containers such as centrifuge tubes and the like for storage, and the operation method is simple, convenient and practical;

it should be noted that the above-mentioned embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
