Abstract
The utility model discloses a single piston blood drawing testing tube comprising a piston barrel (1), a piston (2), a piston tube (3), a nipple (5) and a needle (5), the testing tube is characterized in that a blood drawing valve (6) is arranged between the piston barrel (1) and the nipple (4), a blood entering valve (7) is arranged in the piston (2), the piston tube (3) is a hollow cavity, a lower end of the piston tube is connected with the piston (2), the piston tube is inserted in the piston barrel (1), a top end of the piston tube is provided with a tube cap (8), and one side of a bottom of the piston barrel (1) is provided with an air vent (9) and a piston cap (10). Compared with blood drawing methods in the prior art, the single piston blood drawing testing tube is simple in structure, easy in usage, good in sealing, the testing tube is time saving and labor saving, blood consuming amount is easy to be controlled, pain of a patient is mitigated, pollution is prevented, and blood testing accuracy is ensured.
Description
Technical field
This utility model relates to a kind of hemostix, specifically a kind of single plug blood drawing censorship test tube.
Background technology
At present, blood drawing and packing test tube before blood test are that segmentation is carried out, and blood drawing is to use syringe, extracts in venous patient, then advances test tube, send control laboratory to be checked.Above-mentioned blood-sampling method, though existing wide popularization and application also has weak point: the one, the sample of first drawing blood, packing test tube then, operation is many, and troublesome poeration is wasted time and energy; The 2nd, it is inaccurate that the blood sample consumption is grasped, and many blood drawings cause the waste of blood, takes out less not enoughly, needs puncture again to extract, and brings misery to patient; The 3rd, test tube is in transfer process, and blood sample is because of blow-by, and is easily infected, affects the accuracy of blood test.
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 the blood consumption is easily grasped, and alleviates patient's misery, and good seal is avoided polluting, and guarantees single plug blood drawing censorship test tube of blood test accuracy.
For reaching above purpose, technical solution adopted in the utility model is: this list plug blood drawing censorship test tube, consisted of by piston cylinder, piston, piston tube, nipple, syringe needle, and it is characterized in that establishing the blood drawing valve between piston cylinder and nipple, establish in piston into the blood valve, piston tube is cavity, and the lower end is connected with piston, inserts in piston cylinder, pipe cap is established in the upper end, for making the air in piston, conveniently get rid of, one side is established air vent and cock cap in the bottom of piston cylinder.This utility model is also implemented by following measure: described piston cylinder, establish the consumption scale on its outer wall.When using this utility model, medical personnel first pull up the cock cap on piston cylinder, then arrest pipe cap, at the bottom of piston is shifted onto tin, clean Bas Discharged, again cock cap is inserted in air vent, after preparation is completed, begin blood sampling, after puncturing successfully, the pull pipe cap, the blood drawing valve is opened, and blood sample enters in piston cylinder, when consumption reaches requirement, stop the pull pipe cap, syringe needle is extracted out pulled up, then promote pipe cap, the piston compression blood sample is opened into the blood valve, close the blood drawing valve, blood sample enters in piston tube, completes blood sampling; Blood sampling finishes to open cock cap again, and piston and piston tube are extracted out in piston cylinder, wipes the blood on piston, send control laboratory to be checked blood sample in piston tube.
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, the blood consumption is easily grasped, and alleviates patient's misery, and good seal is avoided polluting, and guarantees the advantage of blood test accuracy.
Description of drawings
Fig. 1 is that this utility model structure master looks partial schematic sectional view.
The specific embodiment
Make this utility model with reference to accompanying drawing 1.This single plug blood drawing censorship test tube, consisted of by piston cylinder 1, piston 2, piston tube 3, nipple 4, syringe needle 5, it is characterized in that establishing blood drawing valve 6 between piston cylinder 1 and nipple 4, establish in piston 2 into blood valve 7, piston tube 3 is cavity, and the lower end is connected with piston 2, inserts in piston cylinder 1, pipe cap 8 is established in the upper end, and a side is established air vent 9 and cock cap 10 in the bottom of piston cylinder 1.Described piston cylinder 1 is established consumption scale 11 on its outer wall.
Claims (2)
1. a list is filled in blood drawing censorship test tube, consisted of by piston cylinder (1), piston (2), piston tube (3), nipple (4), syringe needle (5), it is characterized in that establishing blood drawing valve (6) between piston cylinder (1) and nipple (4), establish in piston (2) into blood valve (7), piston tube (3) is cavity, the lower end is connected with piston (2), insert in piston cylinder (1), pipe cap (8) is established in the upper end, establishes air vent (9) and cock cap (10) in the bottom of piston cylinder (a 1) side.
2. single plug blood drawing censorship test tube according to claim 1, is characterized in that described piston cylinder (1), establishes consumption scale (11) on its outer wall.
