Abstract
The utility model discloses a blood drawing device for test and belongs to the technical field of medical test instruments. The blood drawing device comprises a blood accommodating test tube and a blood drawing needle, wherein a piston is arranged in the blood accommodating test tube and is connected with a pull rod communicated with an inner cavity; the other end of the pull rod is connected with the blood drawing needle through a blood conduit; and an annular convex rib is arranged on the outer wall at the tail of the blood accommodating test tube. The blood drawing device disclosed by the utility model has the advantages of simple structure, convenience in operation, time and labor economization and no pollution to a blood sample; and the accuracy of test and diagnosis is improved and the work difficulty of medical staff is reduced.
Description
Technical field
This utility model relates to a kind of medical inspection apparatus, and blood-taking device is used in especially a kind of check.
Background technology
At present, employed hemostix generally is a disposable syringe, thrusts veins beneath the skin to puncture needle during blood sampling; Injecting tube is for check behind the blood sample collection, so operates cumbersomely, wastes time and energy; But also increased the contaminated risk of blood sample; Reduced the accuracy of check, even made the check failure sometimes, had to draw blood again.
Summary of the invention
The technical assignment of this utility model is to provide a kind of check to use blood-taking device to the deficiency of above prior art.
This utility model solves the technical scheme that its technical problem adopted: blood-taking device is used in a kind of check; Comprise and contain blood test tube and blood taking needle; In vitro be provided with piston at said Sheng blood; Said piston links to each other with the pull bar that inner chamber communicates, and the other end of said pull bar links to each other with blood taking needle through emissary vein, on the afterbody outer wall of said Sheng blood test tube, is provided with annular convex rib.
During use, thrust veins beneath the skin to blood taking needle, hold pull bar, be pulled outwardly gently and contain the blood test tube, blood just can be pumped to be contained in the blood test tube, after the finishing collecting, pulls out piston fully and to get final product.
The utility model has the advantages that: when the medical worker is patient's collecting blood sample; Can directly blood be drawn into and contain in the blood test tube; Do not exist because of shifting the destruction that blood preparation causes once more; Created advantage for the accuracy that improves the assay result, reduced the medical worker simultaneously and contacted and number of operations with blood preparation; Be provided with annular convex rib owing to contain blood test tube tail end outer wall, more help the pull of test tube.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
Below in conjunction with Figure of description this utility model is done following detailed description.
As shown in the figure; Blood-taking device is used in a kind of check; Comprise and contain blood test tube 4 and blood taking needle 1 that in said Sheng blood test tube 4, be provided with piston 6, said piston 6 links to each other with the pull bar 3 that inner chamber communicates; The other end of said pull bar 3 links to each other with blood taking needle 1 through emissary vein 2, on the afterbody outer wall of said Sheng blood test tube 4, is provided with annular convex rib 5.
