Description
Technical field
The invention belongs to the blood testing apparatus field, relate in particular to for erythrocyte sedimentation rate and detect the blood sedimentation tube that uses.
Background technology
Erythrocyte sedimentation rate refers to, anticoagulation is put into blood sedimentation tube vertically leave standstill, and red blood cell is owing to density is sunk greatly.Usually with the distance expression erythrocytic settling velocity of red blood cell end sinking in first hour, be called erythrocyte sedimentation rate (ESR).
In the prior art, the blood sedimentation tube that always uses is made by the glass tube of both ends open 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 by mouth and make the blood sedimentation tube decompression, in order to will be added with anticoagulant, for example, the blood that is added with 3.8% sodium citrate is sucked in the blood sedimentation tube, until till zero on the scale (basic point), or till blood being sucked 0 of the scale of blood sedimentation tube with syringe etc.After vertically being left standstill, this blood sedimentation tube measures erythrocytic sedimentation state every a set time.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.Although this operation simply but will skillfully and be wasted staff, be lost time, if corpse or other object for laboratory examination and chemical testing number can't be processed in the short time in many times.And in the process that Inspection carries out, medical worker may be by disease on the blood infection, and for example, the nosocomial infections such as virus hepatitis, AIDS are sick.
For this reason, publication number is that the patent documentation of CN1176387A discloses two kinds of blood sedimentation tubes, the first at internal diameter evenly and be inserted with the porous resin that ventilation body do not see through liquid in the plastic conduit of both ends open and consist of blood sedimentation tube, during use, the liquid inflow entrance side of blood sedimentation tube is inserted in the blood of blood sampling, make blood sedimentation tube (pump is inhaled or mouth is inhaled) decompression by the other end, can make whereby blood most, simultaneously, directly be drawn into the insertion position of poriness synthetic resin body, read blood post scale, can measure erythrocytic settling velocity, but this scheme is because need to inhale or mouth suction enforcement decompression by pump, so operation or loaded down with trivial details inconvenience; It two is evenly and in the plastic conduit of both ends open to be inserted with an end tool piston portion and the clava (pitch brace) longer and more soft than plastic conduit at internal diameter, during use, the blood that is added with the Anti-solidification agent is packed in the test tube, the liquid inflow entrance side of plastic conduit is inserted in the blood of test tube, piston portion is overlapped like that with the position of the liquid inflow entrance of plastic conduit to be inserted, the claval other end of pulling under this state, make the lower end of piston portion be positioned at 0 scale position of plastic conduit, read blood post scale, can measure erythrocytic settling velocity.But, this scheme pitch brace length is longer, lifting needs to remove redundance after putting in place, corresponding easily broken position generally is set so that cut off thereon, if adopt scissors to cut off not have operation convenience, if manually fracture then operating difficulties, and easily make piston portion depart from 0 scale position, affect detection accuracy.
In addition, in the prior art, the blood sample that gathers generally is to be kept in the test tube that is added with in advance anti-coagulants to shift or preservation, during detection, the liquid upstream end of blood sedimentation tube is inserted in vitro, inhale by pump again or the pitch brace operation, blood is sucked into the zero graduation position of blood sedimentation tube, then be placed on the special stand and leave standstill, in order to guarantee vertically leaving standstill of blood sedimentation tube, avoid blood sedimentation tube obliquity effects testing result, generally test tube and blood sedimentation tube need to be located respectively and be fixed on the special stand, manufacturing cost and the manufacture difficulty of special stand can be increased so undoubtedly, also the complex operation degree can be increased simultaneously.
For this reason, the inventor has designed a kind of blood sedimentation tube assembly, have simple in structure, use easy to operate, the sample contamination risk is little, low cost of manufacture, detect and wait accurately and reliably advantage, when depositing, sample liquid is closed in vitro, in vitro can place in advance anti-coagulants, during detection, directly the liquid upstream end with the blood sedimentation tube body inserts pipe close, and bigger power can connect blind hole, and body is entered tubular container inside, when body and liquid storing part interference fit and when continuing to enter, the effect of being squeezed of sample liquid in the liquid storing part enters in the pore of blood sedimentation tube body and rises, until arrive the zero graduation line position, assembly is placed on vertically leaves standstill observation on the support and get final product.The present invention relates to use therein blood sedimentation tube.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this invention is to provide a kind of blood sedimentation tube, simple in structure, to use easy to operately, the sample contamination risk is little, low cost of manufacture.
To achieve the above object, the present invention has adopted following technical scheme:
A kind of blood sedimentation tube, comprise body, the lower open end of described body is liquid inlet, the upper open end of described body is installed the liquid-blocking unit that can discharge and stop for the body Air liquid ejection in the body, described liquid-blocking unit comprises connecting pipe and end plug, the pore of connecting pipe is cut off and is separated into lower pore and upper pore, cut off central authorities and be provided with the center intubate coaxial with the connecting pipe pore, the bottom of center intubate is positioned at lower pore, the top of center intubate is positioned at pore, and the center pit of center intubate is communicated with lower pore and upper pore; The upper open end of described body inserts in the lower pore of connecting pipe, the upper open end endoporus wringing fit of the bottom of center intubate and body, described end plug plug is contained in the upper pore of connecting pipe, vacate airspace between the bottom of end plug and the center intubate, the bottom of end plug is provided with air hole, and the central hole location of air hole and center intubate staggers.Like this, the circuitous channel that the mouth of pipe of blood sedimentation tube body consists of via pore on intubate center pit, the connecting pipe and end plug air hole is communicated with outside, increased the Bas Discharged resistance, the ascending velocity of sample liquid in the body pore slowed down, avoid the sample liquid ejection, even there is the fraction sample liquid to surpass the zero graduation line, also can be deposited in the upper pore of connecting pipe, can not affect testing result.Further preferred, the bottom of described end plug is provided with a groove, and intubate top, described center is inserted in the groove and clearance fit with it, and the buffering effect of back-shaped like this passage is better.
