Abstract
The utility model provides a dialysis bag buoyancy clip which is used for solving the problem that a clip used at present cannot be used for carrying out quick dialysis in a mode of stirring by matching and using magneton. The dialysis bag buoyancy clip comprises two clip pieces and a shaft connected with the two clip pieces, wherein the other end parts of the clip pieces are provided with grooves and elastic bumps, the grooves and the elastic bumps can be buckled and connected, and the clip pieces are provided with foam blocks. According to the dialysis bag buoyancy clip, through the structures of the clip pieces, the foam blocks are increased, so that the dialysis bag buoyancy clip has the function of buoyancy so as to guarantee that a dialysis bag can sink to be below the liquid level water or a buffer liquor; and meanwhile, the dialysis bag cannot sink to the bottom of the liquid level without influencing the normal working of the magneton, the matching use of the clip and the magneton is realized, the dialysis speed is improved, the dialysis time is shortened, and the working efficiency is improved. In the dialysis bag buoyancy clip, the clip pieces and the foam blocks are connected in a mortise and tenon joint mode, so that mounting and replacement are quite convenient, and operations are simple.
Description
Technical field
The utility model relates to the medical experiment assistive device, a kind of bag filter buoyancy folder that is specifically related to.
Background technology
In the preparation process of large biological molecule, often utilize dialysis to remove salt, organic solvent, biological micromolecule impurity in the sample.The bag filter that uses in the dialysis procedure be by the pellicle of special use per sample amount of solution be folded into bag-shapedly accordingly, make with the clip clamping at the sack place.At first the large biological molecule sample solution is inserted in the bag during dialysis, then with immersing in water or the buffer solution behind the clip clamping sack, the large biological molecule of the macromolecule in the sample solution is trapped within the bag, and the materials such as salt and little molecule constantly diffusion dialysis outside bag, until the concentration on the inside and outside both sides of bag reaches balance.
During dialysis, in order to accelerate dialysis speed, except repeatedly changing the dislysate, also can use magneton to stir.But the clip that uses at present only comprises three parts of two intermediate plates and the axle that is connected two intermediate plates, wherein, the other end of intermediate plate is provided with groove and the elastic projection that can be fastened and connected, this clip clips on the bag filter rear owing to there is not buoyancy member can directly sink to bag filter the bottom of water or buffer solution, cause when dialysis, can't use the mode of magnetic force rotor (the being designated hereinafter simply as magneton) stirring that can accelerate dialysis speed.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of bag filter buoyancy folder for the problems referred to above, is used for solving the clip that uses at present and can't be used the problem that mode that magneton stirs is dialysed fast.
The utility model is achieved through the following technical solutions: bag filter buoyancy folder, comprise two intermediate plates and the axle that is connected two intermediate plates, and wherein, the other end of intermediate plate is provided with groove and the elastic projection that can be fastened and connected, and is provided with foam block on the described intermediate plate.
As further improvement of the utility model, can outwardly tenon be set at intermediate plate, the tongue-and-groove that caves inward is set on the foam block, after tenon plug-in mounting tongue-and-groove is interior intermediate plate is connected with foam block.
As further improvement of the utility model, described foam block peripheral side is provided with tongue-and-groove.
Adopt the good effect of technique scheme:
1, the utility model is by the structure of intermediate plate, increased and had foam block, had buoyancy function, when having guaranteed dialysis, bag filter can sink under water or the buffer solution liquid level, bag filter also can not sink to the bottom of liquid level simultaneously, do not affect the normal operation of magneton, realized being used of clip and magneton stirring, accelerated dialysis speed, shorten dialysis time, improved operating efficiency;
2, the connected mode of intermediate plate and foam block employing Tenon in the utility model installs and changes very convenient, simple to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 intermediate plate, 2 axles, 3 grooves, 4 elastic projections, 5 foam blocks, 6 tenons, 7 tongue-and-grooves.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1, bag filter buoyancy folder described in the utility model is a kind of in order better to be used with the magneton agitating mode in dialysis procedure, carries out improved clip in former structure with typical clamp.Before the improvement, only comprise two intermediate plates 1 and the axle 2 that is connected two intermediate plates in the structure, simultaneously, be provided with groove 3 and the elastic projection 4 that can be fastened and connected in the other end of intermediate plate 1.During use, directly clip is combined on the sack and gets final product.Although simple and convenient, the very easy bottom of sinking to water or buffer liq can't use magneton to stir.
, improve at original intermediate plate for this reason, after the improvement, be provided with foam block 5 on the intermediate plate 1.Foam block 5 can be commonly used the floating in laboratory, also can select commercially available cystosepiment, and cutting forms.By the buoyancy of foam block 5, bag filter is sunk in the liquid level, float on the liquid level after the clip clamping after the dialysis sack is modified, realized being used of clip and magneton stirring, accelerated dialysis speed, shortened dialysis time, improved operating efficiency; Effectively solved the problem that bag filter in the former dialysis procedure directly sinks down into liquid bottom, the direct result that bag filter sinks to the liquid level bottom can't stir to accelerate the express delivery of dialysing with magneton exactly.
In addition, consider the convenient problem of installing and changing, can make further improvements at the binding site of intermediate plate 1 and foam block 5, intermediate plate 1 and foam block 5 are set to the connected mode of Tenon, specifically on intermediate plate 1, outwardly tenon 6 is set; On foam block 5, the tongue-and-groove 7 cave inward is set, after tenon 6 plug-in mounting tongue-and-grooves 7 are interior intermediate plate 1 is connected with foam block 5.In order to prolong the service life of foam block 5, after the tongue-and-groove that also can be provided with in the peripheral side of foam block 5 tongue-and-groove 7, one sides damages, can use the tongue-and-groove of other sides, and the foam block that need not more renew has again reduced the apparatus cost depletions of dialysis procedure, has reduced the expense expenditure.
After the use, foam block 5 can be taken off from intermediate plate 1, be convenient to preserve after separating.
