Abstract
A novel vacuum blood collection tube comprises a blood collection test tube, a rubber plug and an end cover, wherein the end cover (1) of the vacuum blood collection tube is of a plastic tubular structure, one end of the end cover (1) is a flat through hole, the other end of the end cover (1) is a tapered through hole, a circle of flange (11) is arranged on the inner wall of the end cover (1), the rubber plug is tightly installed on the blood collection test tube (3) through the end cover, the small-diameter end of the rubber plug (2) of the vacuum blood collection tube is pressed into the through hole of the end cover through a flat end (12) of the end cover and is tightly installed in the blood collection test tube (3), and after the large-diameter end of the rubber plug is inserted into the through hole through the flat end (12) of the end cover, the circle of flange (11) on the inner wall of the end cover clamps the large-diameter end of the rubber plug. Due to the adoption of the structure, the novel vacuum blood collection tube effectively prevents the possibility that the rubber plug falls off independently when the blood collection test tube is fed to a centrifugal machine, guarantees the personal safety of medical staff in the process of blood sample detection after the vacuum blood collection tube samples blood, and is suitable for being used for blood collection in medical treatment departments.
Description
Technical field
This utility model relates to a kind of novel evacuated blood taking tube, belongs to technical field of medical instruments.
Background technology
The blood taking tube of the negative pressure of vacuum that a kind of hospital of vacuum test tube is commonly used, it comprises glass or plastic blood sampling test tube 3, colored skull 4 and rubber stopper 2, as shown in Figure 1.Traditional vacuum test tube is placed on centrifuge when centrifugal, exists skull to come off and rubber stopper is stayed the blood sampling test tube lip reflex.Because the structure of traditional vacuum test tube skull, be that an end is through hole, stay the plastic tube-shape structure of an aperture in the middle of the other end, as shown in Figure 2, rubber stopper snugly fits between blood sampling test tube and the skull, the rubber stopper smaller diameter end is inserted and is placed in the blood sampling test tube, and the rubber stopper larger diameter end is installed in the skull through hole end.When the vacuum blood taking tube was put into centrifuge, if rubber stopper is filled in tension, as long as skull overcomes the friction between rubber stopper and the skull, just be easy to fly off, rubber stopper was still stayed the blood sampling test tube mouth.
Summary of the invention
The purpose of this utility model is, the problem according to existing vacuum test tube exists designs a kind of novel evacuated blood taking tube, and rubber stopper can not stayed the blood sampling test tube mouth behind last centrifuge and skull comes off.
The technical solution of the utility model is that this utility model is made up of blood sampling test tube 3, rubber stopper 2 and skull 1; Skull 1 is that an end is flat mouthful through hole, and the other end is the plastic tube-shape structure of awl mouthful through hole, and skull 1 inwall has a circle flange 11; Rubber stopper snugly fits in the blood sampling test tube 3 by skull.
During assembling, the rubber stopper smaller diameter end is pressed into the skull through hole by flat mouthful of end 12 of skull and snugly fits in the blood sampling test tube 3, and after the rubber stopper larger diameter end was inserted through hole by flat mouthful of end 12 of skull, a circle flange 11 of skull inwall blocked the rubber stopper larger diameter end.A skull awl mouthful end 13 is convenient to blood sampling test tube and is inserted the skull inner via hole for 3 mouthfuls.
The beneficial effects of the utility model are because this utility model vacuum test tube makes the skull flange stop rubber stopper, to have prevented the blood taking tube probability that skull is deviate from separately when last centrifuge effectively.
This utility model is applicable to medical department blood sampling use.

The specific embodiment
The specific embodiment of the present utility model as shown in Figure 3.
A kind of novel evacuated blood taking tube of this utility model embodiment is made up of blood sampling test tube 3, rubber stopper 2 and skull 1; Skull 1 is that an end is flat mouthful through hole, and the other end is the plastic tube-shape structure of awl mouthful through hole, and skull 1 inwall has a circle flange 11; Skull 1 outer surface is provided with the outer anti-skidding perpendicular stricture of vagina 14 of skull.
Rubber stopper 2 snugly fits on the blood sampling test tube 3 by skull 1, the smaller diameter end of rubber stopper 2 is inserted and is placed in the intracranial blood sampling test tube 3, the larger diameter end of rubber stopper 2 is installed in flat mouthful of end 12 through holes of skull, till the flange 11 of skull 1 inwall blocks the rubber stopper larger diameter end.
Claims (2)
1. novel evacuated blood taking tube, comprise blood sampling test tube, rubber stopper, skull, it is characterized in that described vacuum test tube skull (1) is that an end is flat mouthful through hole, the other end is the plastic tube-shape structure of awl mouthful through hole, and skull (1) inwall has a circle flange (11); Rubber stopper snugly fits in the blood sampling test tube (3) by skull;
The smaller diameter end of the rubber stopper of described vacuum test tube (2) is pressed into the skull through hole by flat mouthful of end (12) of skull (1) and snugly fits in the blood sampling test tube (3), after the rubber stopper larger diameter end was inserted through hole by flat mouthful of end (12) of skull, a circle flange (11) of skull inwall blocked the rubber stopper larger diameter end; A skull awl mouthful end (13) is convenient to blood sampling test tube (3) mouthful insertion.
