Abstract
The utility model relates to a disposal hemostix which is an instrument used for taking out media from the human body. The utility model is characterized in that the pipe wall at the opening end of the blood sampling tube (5) is provided with an L-shaped concave groove (7), the stabilizing plate is provided with a convex pillar (8) which is clamped with the concave groove (7), and the concave groove (7) and the convex pillar (8) form a self-locking device. When the utility model is used, the blood sampling tube (5) is rotated, the self-locking device is opened, and the blood sampling operation can be carried out.
Description
This utility model belongs to the apparatus that takes out medium in the human body, specifically a kind of disposable blood taking device.
As everyone knows, existing bushing type hemostix when the blood sampling operation, is stored owing to have gas in blood pressure effect and the suction pipe, is difficult to control effectively blood sampling volume.
This utility model purpose is, provides a kind of and prevents inventory of gas in the suction pipe, and can control the disposable blood taking device of blood sampling volume effectively.
To achieve the above object of the invention, this utility model can realize that the tube wall of blood taking tube opening is provided with " L " type groove by following measure, and steadying plate is provided with a projection that fastens with groove.
This utility model projection and groove form self-locking device, can prevent inventory of gas in the suction pipe, and can control blood sampling volume effectively.
This utility model is described in detail by embodiment below in conjunction with accompanying drawing, wherein
Fig. 1 is structural representation of the present utility model.
Shown in Figure 1, syringe needle 1 is installed in steadying plate 2 one ends, 2 two relative sides of steadying plate are flat shape, steadying plate 2 with in establish suction pipe 3 tube core 4 be structure as a whole, syringe needle 1 communicates with suction pipe 3 through steadying plate 2, tube core 4 is not held and is provided with rubber piston 6, piston 6 central authorities have the through hole 9 that links to each other with suction pipe 3, tube core 4 is installed in intracavity in the blood taking tube 5 together with piston 6, and be slidingly matched with blood taking tube 5, have " L " connected in star 7 on the tube wall of blood taking tube 5 nose ends, be processed with projection 8 on the steadying plate 2, this projection 8 is fastened in " L " connected in star 7, be positioned at the translot of " L " connected in star 7 at peacetime state projection 8, thereby it is blood taking tube 5 and steadying plate 2 is sealed, when this utility model uses, after syringe needle 1 inserts blood vessel, rotate blood taking tube 5 gently, projection 8 is entered in the vertical slot by the translot of " L " connected in star 7, then can slide vertically between blood taking tube 5 and the steadying plate 2, blood by syringe needle 1 through steadying plate 2, suction pipe 3, piston 6 enters in the tube chamber of blood taking tube 5 automatically, and the outer wall of blood taking tube 5 is provided with graduation mark, in order to metering and control blood sampling volume, the flat side of steadying plate 2 plays the effect of stable support.
Claims (2)
1, a kind of disposable blood taking device comprises blood taking tube, sealing gasket, tube core, suction pipe, steadying plate, syringe needle, it is characterized in that the tube wall of blood taking tube opening is provided with " L " connected in star, and steadying plate is provided with a projection that fastens with groove.
2, disposable blood taking device according to claim 1 is characterized in that the relative dual-side of said steadying plate is a flat shape.
