Abstract
The utility model relates to the field of biology laboratory apparatuses, and mainly relates to a sucker. The sucker is provided with a pre-drawn glass capillary, a sucker seat and a filter element, wherein the inside diameter of an opening part of the pre-drawn glass capillary is accurately measured; the tail end of the pre-drawn glass capillary is inserted into the a pre-drawn glass capillary end tail end fixing round hole in the sucker seat to realize tight connection; the filter element is plugged into a filter element fixing round hole in the sucker seat to realize tight connection. The sucker is a laboratory tool which is accurate, environmentally friendly, safe, convenient, and applicable to cell- and embryo-related operations.
Description
Technical field
The utility model relates to biology laboratory instrument field, relates generally to a kind of suction nozzle.
Summary of the invention
Background technology
Glass pipette is because advantages such as having good light transmission, corrosion resistance and thermoplasticity becomes biology laboratory, the indispensable instrument of IVF laboratory cell, embryo's associative operation particularly, and wherein Pasteur's moral suction pipe, capillary glass tube are the most frequently used glass pipettes.Fig. 3 has shown structure when conventional Pasteur's moral suction pipe (31), capillary glass tube (32) are used.Before using, tubule section or the capillary glass tube of Pasteur's moral suction pipe are drawn into capillary by heating means temporarily, scrape somewhere by rule of thumb disconnected, by whether suitable to recently judging mouth internal diameter at stereomicroscope and object of reference, operator feel to put again latex suction nozzle after suitable or fixture standby.Different operating, such as the most suitable mouth internal diameter that stripping ovum, transfer ovum, transfer blastaea, transfer biopsy cells etc. require is different, some operation, as shell ovum, to mouth internal diameter, require very strict, Pasteur's moral suction pipe, capillary glass tube that interim drawing meets operation requirements are wasted time and energy, often accurate not.At present, on market, there is Pasteur's moral suction pipe and the capillary glass tube of the various mouth internal diameters that drawn, overcome the accurate not problem of interim drawing.Pasteur's moral suction pipe belongs to medical disposable material, is one of consumptive material that IVF laboratory consumption is large, and its glass weight can reach 40 times of capillary glass tube, easily causes environmental pollution, and the environmental protection more of the relative Pasteur's moral of capillary glass tube suction pipe.But latex suction nozzle, fixture are not the disposable articles for use that make, and belong to non-clean parts.Pasteur's moral suction pipe need to load the air that cotton is extruded for filtering latex suction nozzle while using, and capillary glass tube filling cotton is very difficult, directly injects fixture during use, and uncleanly fixture contamination of cells, embryo's risk increases; And the mode that adopts hand-held or tweezers that capillary glass tube is installed to fixture bothers.The plastics suction nozzle with filter core of being used widely at biology laboratory, because the factors such as mouth internal diameter precision is poor, wall thickness do not reach the desired precision of the relevant operation of embryo, is not applied in the operations such as conventional embryo's transfer.
For this reason, the utility model provide a kind of mouth internal diameter that is applicable to cell, embryo's associative operation accurately, environmental protection, safety, suction nozzle easily.
Technical scheme
For achieving the above object, the utility model is taked following technical scheme:
A suction nozzle, has pre-drawing capillary glass tube, suction nozzle seat and filter core.The pre-capillary glass tube that draws has mouth and tail end, and mouth internal diameter is accurately measured through microscope micrometer; Suction nozzle seat axis is provided with fixedly fixedly circular hole and conical interface of circular hole, filter core of pre-drawing capillary glass tube tail end, and three connects.Pre-draw capillary glass tube tail end insert pre-draw capillary glass tube tail end fixedly circular hole form tight connection, filter core fill in filter core fixedly circular hole form tight connection, be assembled into suction nozzle.
During use, according to different operating needs, choose the suction nozzle that mouth internal diameter is suitable, with suction nozzle on the suction nozzle pen cap, carry out cell, embryo's associative operation.
Beneficial effect
1. the utility model suction nozzle adopts pre-draw capillary glass tube, more environmental protection;
2. the pre-drawing capillary glass tube mouth internal diameter of the utility model suction nozzle is accurately measured through microscope micrometer, more accurate;
3. the utility model suction nozzle filter core effectively reduces cell, the contaminated risk of embryo, safer.
?below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is suction nozzle explosive view in the utility model;
Fig. 2 is cross-section of a cleaner head view in the utility model;
Fig. 3 is conventional Pasteur's moral suction pipe and the capillary glass tube stereogram using.
Illustrate
1 suction nozzle, the 11 pre-capillary glass tubies that draw, the 111 pre-capillary glass tube mouths that draw, the 112 pre-capillary glass tube tail ends that draw, 12 suction nozzle seats, the 121 pre-fixedly circular holes of capillary glass tube tail end that draw, 122 filter cores are circular hole fixedly, 123 conical interfaces, 13 filter cores.
The specific embodiment
As shown in Figure 1, a kind of suction nozzle (1), has pre-drawing capillary glass tube (11), suction nozzle seat (12) and filter core (13).The pre-capillary glass tube (11) that draws can adopt external diameter 1.8mm, internal diameter 1.4mm borosilicate glass capillary tube to prepare drawing on pin instrument, total length 4.5cm, there is mouth (111) and tail end (112), mouth (111) to shoulder length is 1.0cm, and mouth (111) internal diameter is accurately measured through microscope micrometer; Suction nozzle seat (12) is medical silica-gel material, and its axis is provided with fixedly fixedly circular hole (122) and conical interface (123) of circular hole (121), filter core of pre-drawing capillary glass tube tail end, and three connects; Filter core (13) is hydrophobic filter core, cylindrical.As shown in Figure 2, draw in advance capillary glass tube tail end (112) insertion and draw in advance the fixedly closely connection of circular hole (122) formation of capillary glass tube tail end, filter core (13) is filled in the fixedly closely connection of circular hole (122) formation of described filter core, is assembled into suction nozzle (1).According to action need, according to mouth (111) internal diameter size, suction nozzle (1) is classified, packed and sterilizes.
According to different needs, choose the suction nozzle (1) that mouth (111) internal diameter is suitable, with suction nozzle penholder, enter the conical interface of suction nozzle (1) (123) formation and closely connect and carry out cell, embryo's associative operation.
Above-described embodiment is only exemplary, not the utility model is done to any pro forma restriction, in the situation that not departing from spirit of the present utility model and principal character, the utility model still may be embodied as that other are multi-form, every any simple modification, equivalent variations and modification of above-described embodiment being done according to technical spirit of the present utility model, all still belongs in the scope of technical solutions of the utility model.
