Description
Technical field:
The present invention relates to medical apparatus and instruments, particularly relate to micro blood-taking tube and pipet improvement.
Background technology:
Common tool when micro blood-taking tube and pipet are the medical department analyzing bloods such as hospital.This micro blood-taking tube is less by internal diameter, both ends open and be communicated with glass tubing make, by one end of micro blood-taking tube and contacting blood to be collected during collection blood, utilize capillary theory, blood to be collected is made automatically to enter micro blood-taking tube inside, the requirement of capacity is generally had when gathering blood, be marked with containing mark at micro blood-taking tube, as 5 microlitres, 10 microlitres, 15 microlitres, 20 microlitres ..., 50 microlitres.The glass tubing that pipet diameter is thinner is made, and also indicates containing mark.Medical worker is when analyzing blood, general first with the blood that micro blood-taking tube collection is quantitative, owing to treating that blood sampling enters the speed of micro blood-taking tube, medical worker removes micro blood-taking tube when often having little time on the scale that blood arrives needs, actual blood sampling volume is caused to be greater than the blood sampling volume of needs, thus when taking out the blood in micro blood-taking tube, not only need micro blood-taking tube to be inserted in the red water dropper of latex, again with the red water dropper of finger extruding latex, just can shift out the blood in micro blood-taking tube, and the amount of taking-up will be controlled, be put into another to fill in the container of diluent or reactant liquor in a lot of situation of the blood taken out by micro blood-taking tube, and then the liquid quantitatively drawn with pipet in container, longer and inaccuracy of whole process used time, also inconvenient, and want cleaning and sterilizing clean after pipet use, every day will use the pipet some with cleaning and sterilizing, cost is also higher, also easily damage.The medical apparatus and instruments that micro blood-taking tube and pipet are combined can be there is not yet at present, also have no data, media record and report.
Summary of the invention:
For the above-mentioned deficiency existing for prior art, technical problem to be solved by this invention to provide a kind of quantitatively trace blood pipet, it has accurately, quantitative collection blood and quantitatively move the function of liquid, the work efficiency of medical worker can be improved, for more people serves, and with low cost, do not need cleaning and sterilizing.
In order to solve the problems of the technologies described above, the scheme of technical solution problem of the present invention is: quantitatively trace blood pipet, comprise both ends open and the micro blood-taking tube be communicated with, both ends open and be communicated with, internal diameter is greater than the tubule of described micro blood-taking tube external diameter and one end open and the squeezable air bag of hollow, the port of described air bag is connected with one end of described tubule, described micro blood-taking tube is made up of water wetted material, described micro blood-taking tube to be inserted in the other end of described tubule and fixing, and the inner chamber of the inner chamber of the inner chamber of described micro blood-taking tube and described tubule and described air bag is interconnected, the tube wall of described tubule is provided with the passage with the inner space of described micro blood-taking tube, described tubule is connected with the reservoir of hollow, the interface that the bottom of this reservoir is connected with described reservoir lower than described tubule, and this interface is positioned at (direction being pointed to described micro blood-taking tube by described air bag is downward direction) on described tubule.
After adopting such scheme, because the port of described air bag is connected with one end of described tubule, described micro blood-taking tube is made up of water wetted material, and to be inserted in the other end of described tubule and fixing, and the inner chamber of the inner chamber of the inner chamber of described micro blood-taking tube and described tubule and described air bag is interconnected, the tube wall of described tubule is provided with the passage with the inner space of described micro blood-taking tube, thus can there is capillarity in micro blood-taking tube and contacting blood, treat that blood sampling can be easy to enter micro blood-taking tube, when taking out the blood in micro blood-taking tube, with finger extruding gasbag, again because described tubule is connected with the reservoir of hollow, the interface that the bottom of this reservoir is connected with described reservoir lower than described tubule, and this interface is positioned on described tubule, this makes the cavity volume be jointly made up of tubule and micro blood-taking tube being positioned at below interface become definite value, and there is quantitative liquid storage and the function of moving liquid.When using as pipet, first extruding gasbag, and micro blood-taking tube is placed in liquid, then loosen air bag, liquid is sucked by air bag, unnecessary liquid flows in reservoir, then quantitative for the present invention trace blood pipet is shifted out liquid and is placed in another container, then extruding gasbag, liquid extruding below interface position in tubule is shifted out, liquid in reservoir because its liquid level is lower than interface position, therefore does not flow out by interface, thus realizes quantitatively moving liquid.Accomplish without any letup in whole use procedure, very convenient, greatly improve accuracy and the speed of operation, overcome quantitative inaccuracy in traditional operation, use the deficiency of duration, and the quantitative trace blood pipet of the present invention is made primarily of plastic and glass pipe, and volume is little, lightweight, with low cost, for disposable products, do not need cleaning and sterilizing, also there is not breakage, the more important thing is owing to improving operating efficiency, can be more people service, patient is got timely medical treatment.
The cross-sectional area of trace blood tube cavity and the product of length are the volume of micro blood-taking tube, (micro blood-taking tube is generally pipe suitably to choose the internal diameter of micro blood-taking tube and length, the cross-sectional area of its inner chamber is determined by internal diameter), the micro blood-taking tube of various capacity specifications can be made.As 5 microlitres, 10 microlitres, 15 microlitres, 20 microlitres ..., 50 microlitres etc.
The cavity volume be jointly made up of tubule and micro blood-taking tube being positioned at below interface becomes definite value, and has quantitative liquid storage and the function of moving liquid, can make the pipet of various capacity specifications.As 50 microlitres, 80 microlitres, 100 microlitres ..., 200 microlitres etc.
The outer wall of described micro blood-taking tube and the inwall of described tubule stick with glue to connect and are fixed together.
Described micro blood-taking tube inserts and is fixed in the inwall of described tubule.
Described air bag is flat.Fixing with finger during convenient operation.
Described air bag is ellipsoid shape.Fixing with finger during convenient operation.
Described micro blood-taking tube is made up of glass.
Described micro blood-taking tube is made up of hydrophilic high molecular material.
Described passage is connected with the valve that outlet is downward.
Described tubule and described air bag become as a whole during fabrication.
Described tubule and described air bag are Split type structure, are fixed together during assembling.
