Abstract
The invention relates to the technical field of vacuum blood sampling, in particular to a centrifugal antiskid coagulation promoting tube which is composed of a left half cap, a rubber plug, a right half cap, bolt strips, buckles, insert slots, a test tube and a cap top, wherein the left half cap and the right half cap form a cylindrical anti-splash cap; at the joint of the left half cap and the right half cap, the buckles respectively positioned on the left half cap and the right half cap are mutually buckled; the side wall of the upper half part of the rubber plug is provided with two insert slots; and two bolt strips are respectively positioned in the two insert slots. According to the centrifugal antiskid coagulation promoting tube, the axial binding force of the rubber plug and the anti-splash cap depends on the combination of the friction force and the bolt fixing force instead of purely depending on the friction force in the prior art, so that the anti-splash cap and the rubber plug are combined more compactly, and biosafety potential risks caused by defective tightness of the combination between the anti-splash cap and the rubber plug in the prior art can be completely eradicated.
Description
Technical field
The present invention relates to vacuum blood drawing technique field, particularly relate to a kind of centrifugal Anti-slip type coagulant pipe.
Background technology
Existing coagulant pipe, conventionally by test tube, fill in the butyl rubber plug of test tube mouth and splash cap three parts that are placed on butyl rubber plug and form.During the blood sample of doctor in taking blood taking tube; need first plug to be extracted from the mouth of pipe; when plug is pulled away moment of test tube; atmospheric pressure forces outside air to pour rapidly in vitro; can cause that the blood sample in pipe outwards splashes from the mouth of pipe; and splash cap has played and has stopped that blood sample splashes, the effect of protection laboratorian's safety.
But in state of the art, the adhesion of splash cap and plug is strong not, this makes blood taking tube in centrifuge, carry out in the process of blood sample separation on the one hand, and splash cap can depart from from plug surface sliding and with plug; On the other hand, when laboratorian pinches splash cap and wants plug together to extract from test tube mouth, splash cap and plug generation relative sliding, splash cap is slided from plug, and plug does not still depart from test tube mouth completely.The generation of these situations, has not only reduced the efficiency of chemical examination work, and has made chemical examination work have potential safety hazard.
Increase the adhesion of splash cap and plug, common technical scheme is the frictional force that increases splash cap and plug, such as the size by increasing plug to increase plug to the lateral pressure of splash cap medial wall etc., although but the technical scheme of this class can strengthen the adhesion of splash cap and plug, but also increased by the two frictional resistance in splash cap and plug assembling process, for assembly working has increased difficulty simultaneously.
Therefore, in prior art, do not have effective technical scheme and can realize and can either make to there is good adhesion between splash cap and plug, can make the assembling process of the two easy again, laborsaving.
Summary of the invention
The present invention, for solving the deficiencies in the prior art, provides between a kind of splash cap and plug and can be combined as a whole easily, but can obtain enough large adhesion, eliminate the centrifugal Anti-slip type coagulant pipe of the probability that splash cap slips away from plug completely.
The scheme that solves the technology of the present invention problem is:
Centrifugal Anti-slip type coagulant pipe, consists of left half cap, plug, right half cap, latch bar, buckle, slot, test tube and crown.
Wherein, left half cap and right half cap be all for by a bottom surface and a cylindrical hollow structure that circular arc side forms, and left half cap and right half cap be common forms a columnar splash cap.At the joining place of left half cap and right half cap, the buckle laying respectively on left half cap and right half cap fastens mutually.In a pair of buckle mutually fastening, one of them buckle has outside fin, another buckle to have inside fin.
On the medial surface of left half cap and right half cap, the latch bar that has respectively an arc, two latch bars are about the axle center centrosymmetry of described splash cap, end face at left half cap has one to be holistic semiorbicular crown with left half cap, end face at right half cap also has one to be holistic semiorbicular crown with right half cap, is positioned at a complete circular hole of the common formation of inward flange of described two crowns of left half cap, right half crown portion.
Plug is the shaft section that consists of the big column of the first half and the small column of Lower Half for falling the rotary body of convex shape.The slot that has two shape sizes with described latch bar to adapt on the sidewall of the first half of described plug, two slots are about the axial line centrosymmetry of plug.Described splash cap is placed on described plug, and splash cap becomes interference fit relation with plug, and two latch bars are respectively in described two slots.
The Lower Half of plug is in test tube suitable for reading and become interference fit relation with test tube.
When assembling plug and splash cap, only need first left half cap and right half cap to be placed in the both sides of plug, two latch bars are aimed at respectively to two slots, by left half cap and right half cap, toward holding together to pinch, the buckle being positioned on left half cap and right half cap fastens mutually.Now, splash cap and plug become the integral body locking together.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
Because two latch bars insert in respectively in two slots; therefore; plug and splash cap be the mode by traditional pure dependence frictional force in axial adhesion; change into the mode that frictional force combines with latch bed knife; this makes the combination of splash cap and plug more tight; existing splash cap and plug have been stopped in centrifuge, because the situation in conjunction with the frequent slippage of defective tightness occurs.Also avoid medical worker's splash cap in opening the splash cap of test tube mouth and the process of plug to depart from plug, eliminated the bio-safety hidden danger causing thus.

The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Centrifugal Anti-slip type coagulant pipe, consists of left half cap 1, plug 2, right half cap 3, latch bar 4, buckle 5, slot 6, test tube 7 and crown 8.
Wherein, left half cap 1 and right half cap 3 be all for by a bottom surface and a cylindrical hollow structure that circular arc side forms, and left half cap 1 and right half cap 3 be common forms a columnar splash cap.At the joining place of left half cap 1 and right half cap 3, the buckle 5 laying respectively on left half cap 1 and right half cap 3 fastens mutually.In a pair of buckle 5 mutually fastening, one of them buckle 5 has outside fin, another buckle 5 to have inside fin.
On the medial surface of left half cap 1 and right half cap 3, the latch bar 4 that has respectively an arc, two latch bars 4 are about the axle center centrosymmetry of described splash cap, end face at left half cap 1 has one to be holistic semiorbicular crown 8 with left half cap 1, end face at right half cap 3 also has one to be holistic semiorbicular crown 8 with right half cap 3, is positioned at a complete circular hole of the common formation of inward flange of described two crowns 8 at left half cap 1, right half cap 3 tops.
The Lower Half of plug 2 in test tube 7 suitable for reading and with 7 one-tenth interference fit relations of test tube.
When assembling plug 2 and splash cap, only need first left half cap 1 and right half cap 3 to be placed in the both sides of plug 2, two latch bars 4 are aimed at respectively to two slots 6, by left half cap 1 and right half cap 3, toward holding together to pinch, the buckle 5 being positioned on left half cap 1 and right half cap 3 fastens mutually.Now, splash cap and plug 2 become the integral body locking together.
