Description
Technical Field
The utility model relates to an kinds of blood sedimentation tubes with direction function.
Background
The existing process of taking out the blood sample in the vacuum blood sedimentation tube is to pull the plastic splash-proof cap and the rubber plug of the vacuum blood sedimentation tube out of the test tube opening and then extend the injection needle into the liquid for extraction, because the negative pressure exists in the blood sedimentation tube, at the moment that the rubber plug is pulled out of the test tube, the outside air is flushed into the tube, the blood in the tube can splash outwards, although the existing vacuum blood sedimentation tube is provided with the splash-proof cap outside the rubber plug, the contact of the blood with an operator can not be completely avoided, because the splashed amount of the blood is larger, the blood still flows out along the lower edge of the inner wall of the splash-proof cap, the existing test sampling mode still has the risk of , therefore, the medical worker always has very slow and small wing wings in the process of pulling the rubber plug, and the working efficiency of blood sample analysis is also reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an kinds of blood sedimentation tubes with direction function.
The utility model discloses a following technical scheme can realize.
The utility model provides an kinds of blood sedimentation tubes with direction function, including body, stopcock, the opening part at the body is installed to the stopcock, the stopcock includes interconnect's interior stopper and outer edge, interior stopper sets up in the opening of body, outer edge sets up the opening outer end at the body, the axial direction of interior stopper be provided with the body internal connection's passageway, install stand pipe and needle tubing in the passageway.
The guide pipe is installed in the inner plug and is connected with the lower edge of the positioning opening in the center of the outer end of the inner plug.
The needle tube is arranged in the inner plug, the end of the needle tube is connected with the guide tube, and the other end of the needle tube extends into the tube body.
The inner plug is also provided with a lower limiting table and an upper limiting table in the channel respectively, the lower limiting table and the upper limiting table are arranged at the opening of the needle tube, and a spring 5 is arranged between the lower limiting table and the upper limiting table.
The needle tube is fixedly connected with a sealing piece, the upper end and the lower end of the sealing piece are respectively connected with the upper limiting table and the spring 5, and a plurality of rubber plugs are fixedly connected at the upper opening and the lower opening of the inside of the needle tube.
The sealing element is trapezoidal, and a groove matched with the shape of the sealing element is formed in the lower end of the upper limiting table.
The beneficial effects of the utility model reside in that: through set up the direction passageway in the blood sedimentation tube piston, prevent that the syringe from because the too thick problem of damaging the needle point of piston in the blood sample extraction process, the piston of thickening also can be better seals the blood in the blood sedimentation tube.
