The blood collection tube disclosed by the invention can avoid the generation of negative pressure inside veins nearby a puncture needle and can relieve discomfort caused by blood drawing.
Description
Technical field
The present invention relates to a kind of medical treatment blood sampling apparatus, particularly relate to a kind of blood taking tube that can regulate transfusion speed.
Background technology
China is populous nation, along with growth in the living standard, people pay close attention to the healthy of self more, medical consumable goods in disease treatment and prevention health check-up increases, blood taking tube particularly as main bases blood sampling chemical examination consumes huge, existing most of blood taking tube inside is all vacuum and has medicament, after venipuncture, blood taking tube is thrust in another hose connection for piercing needle termination during blood sampling, by the internal negative pressure of blood taking tube by venous blood suction blood taking tube, although it is quick, but be different from needle tubing blood drawing, can by the size adjustment suction of force during needle tubing blood drawing, whole blood drawing process is made to remain on a balanced negative pressure, and whole blood drawing process negative pressure changes from high to low when using blood taking tube to draw blood, blood high velocity stream intravenous near piercing needle is extracted out by high negative pressure in the early stage, near piercing needle, intravenous produces a negative pressure, also have needle tip also can adsorb blood vessel wall, these all can increase the sense of discomfort that blood drawing produces, still need to be improved.
Summary of the invention
In order to solve the problem, the invention provides a kind of blood taking tube that can regulate transfusion speed.
The technical solution used in the present invention is: a kind of blood taking tube that can regulate transfusion speed, comprise blood-collecting tube, cork and vinyl cover, it is characterized in that vinyl cover top is provided with insert port, vinyl cover inside is provided with ring-shaped depression by the sidewall at top, cork is provided with the annular seal groove that blood-collecting tube opening port inserts, cock body outside annular seal groove embeds in ring-shaped depression, vinyl cover inwall is provided with the cannelure being extended to ring-shaped depression by edge, vinyl cover sidewall is provided with longitudinal opening, resilient strip is provided with in longitudinal opening, resilient strip is connected away from side, vinyl cover top with longitudinal opening, resilient strip free end is connected with the projection of outstanding vinyl cover side wall inner surface, protruding and ring-shaped depression possesses spacing, vinyl cover edge is provided with along extending the elasticity arm of blood-collecting tube outer wall to downward-extension, and elasticity arm is provided with gap near blood-collecting tube outer wall side.
Further, described gap is two or more, and along the distribution of elasticity arm bearing of trend, each gap shoals gradually to vinyl cover edge direction.
Further, described elasticity arm termination is close blood-collecting tube outer wall side is inclined-plane.
Further, described gap is step-like at elasticity arm bearing of trend.
Further, described elasticity arm and blood-collecting tube overcoat have snap ring.
Further, described snap ring is elastic force ring.
Further, described elasticity arm is connected with vinyl cover by clamp.
Further, described elasticity arm is provided with longitudinal breach, is connected with elastic arm in longitudinal breach, and elastic arm is connected with the briquetting that can overwhelm in gap at opening position.
In the depression of the hose clamp that piercing needle can connect when taking a blood sample by the present invention between elasticity arm and blood-collecting tube, the blood flow under initial stage high negative pressure effect can be reduced under elasticity arm clamping, intravenous near piercing needle is avoided to produce negative pressure, reduce the sense of discomfort that blood drawing produces, and longitudinal gap can carry out evacuation and the depth localization of evacuation protecgulum lid better with protruding arranging, and does not affect evacuation rear pressing cover again.
