Abstract
The utility model discloses a venous blood drawing test tube which comprises a cylinder body 1, a piston 2, a piston rod 3 and a nipple 4, and is characterized in that the front end of the nipple 4 is inserted into a nipple hole 6 of a cylinder body seat 5; one end of the piston rod 3 is connected with the piston 2, and the other end of the piston rod is provided with a cylinder body plug 7; the middle of the piston rod is provided with a breaking groove 8; and the outer wall of the cylinder body 1 is provided with scale 9. Compared with the existing blood taking method, the venous blood drawing test tube has the advantages of being simple in structure, convenient to use, time-saving, labor-saving, good in sealing, free from pollution and guaranteeing the examination quality.
Description
Technical field
This utility model relates to a kind of improvement of medical test tube, specifically a kind of vein haemospasia test tube.
Background technology
Blood test is patient diagnosed's cause of disease, effective means commonly used.At present, blood sampling and packing test tube before the blood test are that segmentation is carried out, and blood sampling mainly is to extract from patient's intravenous with syringe, advances test tube then, send control laboratory to be checked.Above-mentioned blood-sampling method, though existing wide popularization and application also has weak point: the one, blood drawing sample earlier, packing test tube then, blood-sampling method is cumbersome, wastes time and energy; The 2nd, test tube is in transfer process, and is easily infected because of blow-by, influences quality inspection.
Summary of the invention
It is a kind of simple in structure, easy to use, time saving and energy saving that the purpose of this utility model is to provide, and good seal is avoided polluting, and guarantees the vein haemospasia test tube of quality inspection.
For reaching above purpose, technical solution adopted in the utility model is: this vein haemospasia test tube, comprise: cylindrical shell, piston, piston rod, nipple constitute, it is characterized in that the nipple front end inserts in the papillary foramina of cylindrical shell seat, piston rod one end connects piston, the other end is established the cylindrical shell plug, and snap slot is established in the centre, establishes scale on the outer wall of cylindrical shell.This utility model is also implemented by following measure: described cylindrical shell plug, its external diameter is consistent with the cylindrical shell interior diameter, for prevent to cause cross infection, and establish the packing plastics film when the insertion cylindrical shell is suitable for reading.When using this utility model, medical personnel pull up the cylindrical shell seat earlier from nipple, syringe needle then is installed on nipple, puncture to patient's intravenous again, after puncturing successfully, pull cylindrical shell plug is when the blood pull arrives quantitative scale, stop pull cylindrical shell plug, syringe needle is extracted from patient's vein, again syringe needle is taken off, be installed in the cylindrical shell seat on the nipple again, then piston is extracted out in cylindrical shell, from the snap slot of piston rod piston is removed, remove cylindrical shell packing plastics film beyond the Great Wall again, it is suitable for reading with cylindrical shell plug insertion cylindrical shell to arrest piston rod, cylindrical shell has become test tube like this, can directly send control laboratory to be checked.
The beneficial effects of the utility model are: compare with present blood-sampling method, have simple in structurely, easy to use, time saving and energy saving, good seal is avoided polluting, and guarantees the advantage of quality inspection.
