Abstract
The utility model discloses a disposable vein blood sampling device, which consists of a barrel 1, a piston 2, a piston handle 3, a nipple 4 and a needle 5, and is characterized in that: the inside of the nipple 4 is provided with a blood feeding valve 6; one side of the lower end of the barrel 1 is provided with a blood discharging valve 7; the lower end of the nipple 4 is provided with a barrel base 8; and the barrel 1 is provided with scales 9. The disposable vein blood sampling device has the advantages of convenient, time-saving and labor-saving operation, complete seal, no infection and guarantee of assay quality compared with the conventional blood sampling methods.
Description
Technical field
This utility model relates to a kind of improvement of blood collection needle, specifically a kind of disposable vein blood-taking device.
Background technology
Blood testing is patient diagnosed's cause of disease effective means commonly used.At present, mainly take a blood sample earlier from patient's intravenous with syringe, again according to lab work be divided in vitro carry out to be checked, above-mentioned blood-sampling method, though existing wide popularization and application also has weak point: the one, the sample of drawing blood earlier, packing test tube then, blood collection procedure is cumbersome, wastes time and energy; The 2nd, test tube is blow-by in transfer process, and is easily infected, influences analytical quality.
Summary of the invention
It is a kind of simple in structure, easy to operate, time saving and energy saving that the purpose of this utility model is to provide, and sealing is avoided infection fully, guarantees the disposable vein blood-taking device of analytical quality.
For reaching above purpose, technical solution adopted in the utility model is: this disposable vein blood-taking device, constitute by cylindrical shell, piston, piston handle, nipple, syringe needle, it is characterized in that in nipple, establishing into blood valve, establish row's blood valve in the lower end of cylindrical shell one side, place for ease of cartridges stand, also establish the cylindrical shell seat, on cylindrical shell, establish scale in the lower end of nipple.This utility model is also implemented by following measure: describedly advance the blood valve, by advancing the blood valve spring, advancing blood valve valve ball and constitute, advance the blood valve spring and advance blood valve valve ball to be installed in the nipple; Described row's blood valve is made of row's blood valve body, row's blood valve spring, row's blood valve valve ball, row's blood vessel, and row's blood valve body one end is connected with cylindrical shell, and the other end joins with row's blood vessel, and row's blood valve spring and row's blood valve valve ball are installed in row's blood valve body.When using this utility model, the medical worker pulls up the cylindrical shell seat earlier, then punctures to patient's intravenous, after puncturing successfully, the pull piston handle advances the blood valve and opens, row's blood valve cuts out, blood is sucked in the cylindrical shell, when pull arrives quantitative scale, stops the pull piston handle, syringe needle is extracted from patient's vein, again syringe needle is taken off, the cylindrical shell seat is installed on the nipple again, can directly send the laboratory to be checked the cylindrical shell that has blood like this; During as needs blood, promote piston handle, advance the blood valve and close, row's blood valve is opened, and blood flow into the required vessel from row's blood vessel.
The beneficial effects of the utility model are: compare with present blood-sampling method, have easy to operately, time saving and energy saving, sealing is avoided infection fully, guarantees the advantage of analytical quality.
