The tube is inserted into the stipulated position through any opening of a compound resin tube with even internal diameter and openings on both ends; the other opening is treated as a liquid inlet. The present invention is characterized in that the compound resin tube is marked with scale from the liquid inlet. When inserting the porous compound resin body, one end face should be treated as the starting point of the scale. A rod body with a piston longer and softer than the compound resin tube is inserted into the compound resin tube and the piston is located in the liquid inlet. The liquid inlet is inserted into the blood and the piston is moved to the starting point of the scale, thus suctioning the liquid into the starting point of the compound resin tube.
Description
The present invention relates to blood sedimentation tube, in more detail, is to be inserted with a kind of prodigiosin and to see through gas but do not make liquid see through the plastic blood sedimentation tube of the poriness synthetic resin body of characteristic about interior.
The blood sedimentation tube that always uses in the prior art is made by the glass tube of both ends open, length 30cm and internal diameter 3mm.This glass tube is put on a scale every 1mm in distance one openend 20cm scope.When using the blood sedimentation tube of this kind prior art, at first must inhale and make the blood sedimentation tube decompression by mouth, so that will be added with anticoagulant, for example, the blood that is added with 3.8% sodium citrate is sucked in the blood sedimentation tube, till zero on the scale (basic point), or till blood being sucked 0 of the scale of blood sedimentation tube with syringe etc.Make this blood sedimentation tube vertically leave standstill the back then and measure erythrocytic sedimentation state every a set time.After erythrocyte sedimentation rate detects termination, will be clean, sterilization, drying with the blood sedimentation tube of crossing, simultaneously, with the use of regenerating of used blood sedimentation tube.
But, when using the blood sedimentation tube of this prior art to carry out blood sedimentation, must directly suck or use syringe that blood is sucked blood sedimentation tube till the scale zero with mouth.Though this operation simply but will skillfully and be wasted staff, be lost time, if can't handle in the corpse or other object for laboratory examination and chemical testing number short time for a long time.And in checking the process that operation is carried out, or in use cleaning of carrying out, sterilization, dry or the like process for regeneration, medical worker may be by disease on the blood infection, for example, and nosocomial infection diseases such as virus hepatitis, AIDS.And also very waste of manpower in operation is used in regeneration.Again and, be attached to wall through long-term back fat, the protein etc. of using, cause clean incomplete and influence the correctness of data easily.
For addressing these problems, developed recently a kind of be disclosed in real fair 7-9092 number blood sedimentation tube, this kind blood sedimentation tube 21 as shown in Figure 6, make the even and equal opening in two ends of its internal diameter by plastic conduits 22 such as tygon, polystyrene, polypropylene.The lower end of this plastic conduit 22 is provided with flow of liquid inlet 23, and the opening part of upper end then is formed with conical mouths portion 24.The structure of this conical mouths portion 24 can make poriness synthetic resin body 25 be easy to insert the position of regulation in the plastic conduit 22.The blood sedimentation tube 21 that constitutes like this, the footpath evenly within it, and be inserted with the porous resin (macromolecule that contains high-hydroscopicity) that ventilative body does not see through liquid in the plastic conduit of both ends open, therefore, during use, the flow of liquid entrance side of blood sedimentation tube is inserted in the blood of blood sampling, make the blood sedimentation tube decompression, can make the blood majority whereby, simultaneously, directly be drawn into the insertion position of poriness synthetic resin body by the other end.But, on the other hand,, therefore,, will take place not only that gas penetration potential disappears immediately as long as when having small quantity of water droplets or blood to splash into poriness synthetic resin body during use because poriness synthetic resin body has water wettability, and the problem that can't use of blood sedimentation tube.
In addition, because poriness synthetic resin body is water wettability, therefore when poriness synthetic resin body aperture when little and long, owing to can not make the blood stop, so the interior suction pressure of blood sedimentation tube is improved, liquid and super absorbent polymer, for example, when contacting with the cornstarch of xerogel state, the cornstarch that is the xerogel state on the poriness synthetic resin surface will become common gel, moreover, this gel also can flow in the blood sedimentation tube, influences the sedimentation of red blood cell.
Even the present invention unlikelyly when splashing into liquid such as water, blood because of carelessness causes ventilative the disappearance and can't use to provide a kind of, and do not have that to take out the blood sedimentation tube of pressing height or super absorbent polymer to flow in the blood be goal of the invention.
Again, the present invention is to provide a kind of easy and simple to handle, and time cripetura and medical worker can not infect the disease of autoblood, and can to obtain the correct high blood sedimentation tubes of reliability such as detection data be goal of the invention.

Embodiment
Below with reference to the accompanying drawings embodiments of the invention are illustrated.
Fig. 1 to Fig. 3 is for constituting blood sedimentation tube of the present invention.1 is blood sedimentation tube.Blood sedimentation tube 1 shown in Figure 1 is by for example: plastic conduits 2 such as tygon, polystyrene, polypropylene are made.The flow of liquid inlet that the even and both ends open of plastic conduit 2 internal diameters, its bottom have liquid such as making blood to flow into.In addition, then there is conical mouths portion 4 end on the plastic conduit 2.The setting of this conical mouths portion 4 is to make poriness synthetic resin body 5 can be inserted into institute's allocation in the plastic conduit 2 at an easy rate, has ventilative body, but the characteristic that does not allow liquid pass through.
Being stained with super absorbent polymer (xerogel) in the porous plastid that poriness synthetic resin body 5 makes thermoplastic resin powders such as tygon, polypropylene, ethylene-vinyl acetate resin copolymer, polystyrene, acrylic copolymer make through the semi-molten shaping makes.So-called semi-molten shaping is meant above-mentioned thermoplastic resin powder filled in the mould of definite shape, under the purpose of modulating gas porosity, packed layer is pressurizeed, and this powder filled layer is evenly heated, the surface of contact of particle melts under the semi-molten state makes it cooling when gluing, and makes each interparticle empty barrier form forming process of totally continuous three dimensions (pore).So-called super absorbent polymer is meant the macromolecular compounds that water absorptivity is strong, the sealed knot ability is high such as gelatin, cold sky, Arabic gum.So-called xerogel is meant that the macromolecule of high-hydroscopicity is solid state.
In sum, poriness synthetic resin body 5 is stained with the super absorbent polymer of xerogel state in partly melting the porous plastid that gets that is shaped owing to aforementioned thermoplastic resin powder body, though therefore gas permeable such as air, but, liquid such as blood are then when contacting with poriness synthetic resin body 5, understand moment with Liquid Absorption because of the super absorbent polymer of xerogel state, swelling can take place in the super absorbent polymer of xerogel simultaneously, and liquid just can't see through as a result.Again, poriness synthetic resin body 5 is inserted in the gap of synthetic resin 2, be located on 2 the end face, this point is set at 0 point (basic point) with by the 20cm scale places of flow of liquid inlet 3 beginnings with the 1mm scale.
Blood sedimentation tube with shown in Figure 1 is identical basically for Fig. 2 and blood sedimentation tube 7 shown in Figure 3, its difference is, one of be installed in the synthetic resin 2 on the end face, scale is that the poriness synthetic resin body 5 of 0 position changes to insert an end tool piston portion 6 and the clava 7 longer and more soft than synthetic resin 2.This clava 7 is made by a kind of soft synthetic resin, and the one end has the piston portion 6 that can slide in synthetic resin 2, and this clava 7 is longer than plastic conduit 2, and will make the structure that can be inserted in the plastic conduit 2.So the flow of liquid that coincides with plastic conduit 2 when piston portion 6 enters the mouth 3 the time, the other end of clava 7 will be outstanding by the conical mouths portion 4 of plastic conduit 2.In addition, 8 among the figure is on-slip jogs of being located at clava 7 tops, and 9 for making the easily notch to disconnect of clava 7, and 10 is test tube.
Fig. 4 represents the piston portion 6 of two-period form broad-brimmed rain hat type.Even this kind bamboo hat shape piston portion 6 be set be in order to make piston when bigger, also can slide simply easily, to guarantee the effect of piston than the internal diameter of plastic conduit 2.
Fig. 5 represents the user mode of blood sedimentation tube of the present invention.At first, the blood that is added with anti-coagulating agent is packed in the test tube 10, and it is positioned on the brace table 11.Then, by locating support 12 flow of liquid of plastic conduit 23 sides that enter the mouth are inserted in the blood of test tube 10.At this moment, the position of the flow of liquid inlet 3 of piston portion 6 and plastic conduit 2 is overlapped like that insert, this state spurs the other end of clava 7 down, makes the lower end of piston portion 6 be positioned at 0 position of plastic conduit 2, read blood post scale, can measure erythrocytic settling velocity.
Again, hydrophobic nature porous synthetic resin body used herein is thermoplastic resin powder body to be become partly dissolve the shaping thing, and it is made porous body, and this porous body is configured as the shape of defined, impregnated in then in the silicone oil, under 60 ℃ through about 10 to 20 minutes, make its drying.
Below, the using method of the blood sedimentation tube of above-mentioned formation is described in more detail.
At first, prepare blood sedimentation tube 1 of the present invention,, by conical mouths 4 sides of pump plastic conduit 2 is reduced pressure again in case insert the flow of liquid of blood sedimentation tube 13 ends that enter the mouth in the blood that solidifies to being added with sodium citrate, blood is sucked in the plastic conduits 2 by flow of liquid inlet 3 by blood sedimentation tube 1.At this moment, blood arrival scale is 0 position, a that is end face of arrival poriness synthetic resin body 5, end state so the super absorbent polymer of the xerogel state in the adhesion poriness synthetic resin body 5 absorbs the moisture content in the blood immediately and is swelled into envelope, blood just remains in 0 position and stops to flow.Like this, blood being sucked in the blood sedimentation tube 1 and arrive 0 operation just can be simple and easy and carry out in moment.Blood sedimentation tube 1 vertical after at regular intervals measured erythrocytic sedimentation state, and mensuration after used blood sedimentation tube 1 abandoned thereafter.
Formation of the present invention is, internal diameter evenly and the plastic conduit of both ends open, by its arbitrary opening, insert a kind of tool see through gas the poriness synthetic resin body of saturating only characteristics of liquids to institute's allocation, and other end opening is entered the mouth as flow of liquid, constitute blood sedimentation tube thus, it is characterized in that, begin calibrate on plastic conduit by aforesaid liquid inflow entrance end, and the basic point that makes an end face of above-mentioned poriness synthetic resin body become scale inserts poriness synthetic resin body like that in plastic conduit; In addition by aforesaid liquid inflow entrance end to the basic point calibrate, and the end in plastic conduit inserts a kind of piston portion that has and the clava longer and more soft than plastic conduit.Above-mentioned piston region is inserted in the blood in the flow of liquid porch and with the aforesaid liquid inflow entrance, again this piston portion is moved to the basic point of above-mentioned plastic conduit scale, make blood import the basic point of plastic conduit whereby.Above-mentioned plastic conduit is made hydrophobic nature and constitute above-mentioned poriness synthetic resin body with the hydrophobic nature porous body again.And in this hydrophobic nature porous body, the high-hydroscopicity molecule that contains the xerogel shape with respect to this general assembly (TW) is 0.5～10.0 weight %.Again, the arbitrary opening of above-mentioned plastic conduit has the gradient of required scope, and the air pump orifice of the taper guiding longer than above-mentioned poriness synthetic resin body is housed, on institute's allocation in about at least 10 times to 15 times the plastic conduit that apart from this air pump orifice is above-mentioned plastic conduit internal diameter size, be inserted with poriness synthetic resin body, in addition, above-mentioned poriness synthetic resin body is the porous plastid that thermoplastic resin is shaped and obtains through semi-molten, and be stained with the super absorbent polymer of xerogel shape in the body, constitute blood sedimentation tube thus, therefore have the unexistent multiple effect of prior art blood sedimentation tube.
When a. adopting blood sedimentation tube of the present invention, even when accidentally small amount of moisture or blood being splashed into blood sedimentation tube, because synthetic resin body and poriness synthetic resin body in the blood sedimentation tube are hydrophobic material, therefore, water or blood eject while water or blood etc. and also are difficult to arrive super absorbent polymer, and super absorbent polymer does not also have effect.
B. in addition, because poriness synthetic resin body is the hydrophobic nature porous body, so, compare with hydrophilic material, even the aperture is big and length short, blood is stopped.Also blood can be pumped out even swabbing pressure is low.Moreover, water or blood etc. with can be ended by envelope immediately after super absorbent polymer contacts.
C. in addition, owing to be non-water wettability, so super absorbent polymer is difficult to flow into the blood side, therefore, even liquid such as water or blood splash into blood sedimentation tube accidentally, as long as amount is few, this blood sedimentation tube just can use as before, therefore operates simple and convenient.
D. owing to can use the big hydrophobic nature porous hole body in aperture, therefore, also can suction blood even swabbing pressure is low, and the macromolecule that the height of gel state absorbs system also is difficult to flow into blood, can not influence erythrocytic sedimentation state.
E. begin calibrate by the flow of liquid entrance side, because an end face of poriness synthetic resin body is positioned on the basic point of this scale, therefore, liquid such as blood by the open side suction can flow to the scale basic point immediately, and owing to poriness synthetic resin body are arranged so blood can not be extracted on the basic point.So need not regulate till making liquid such as blood flow into the scale basic point, therefore, the benchmark operation of blood sedimentation is simple.
F. again and, blood sedimentation tube can be made by the synthetic resin of cheapness, and by the conical mouths place with poriness synthetic resin body be inserted into fixed position, so blood sedimentation tube can easy making, and can cheap a large amount of blood sedimentation tubes of producing.Therefore also can use up immediately and abandon, use operations such as needs clean, sterilization, drying also can delete for regeneration in the prior art and abandon.
G. in addition, also can eliminate cleaning of occurring in the prior art and not exclusively be attached to the fat of wall, the shortcoming that protein reduces data reliability because of blood sedimentation tube.And owing to there are not these operation process, therefore almost can not worry coming the infection of the diseases such as virus hepatitis, AIDS of autoblood.
H. replace above-mentioned poriness synthetic resin body, replace and adopt an a kind of end to be provided with piston portion and the clava longer and softer than plastic conduit, this clava is inserted in the plastic conduit, make piston be positioned at the flow of liquid inlet, and the flow of liquid inlet is inserted in the blood.Mobile piston portion can import blood plastic conduit to its scale basic point, is therefore also unnecessaryly aspirated by tapered opening portion with vacuum pump etc.As a result, not only easy and simple to handle even on a small scale the time, the also renewable use of clava, so there are many benefits the cost aspect.
