Abstract

The utility model discloses an adapter of a centrifuge for capping off a vacuum blood tube The adapter comprises a main body; a plurality of through holes are formed in the main body; each through hole respectively comprises a large aperture section and a small aperture section respectively adapted with a tube cap and a tube body of the vacuum blood tube; the main body is provided with a slot at the small aperture sections of the through holes, wherein the slot is vertical to the through holes; a clamping plate is arranged in the slot; the bottom of the slot is provided with an elastic component matched with the clamping plate; and a plurality of through holes matched with the small aperture sections of the through holes are formed in the clamping plate. The adapter has the following advantages that: by arranging the elastic clamping plate in the main body, the tube caps of all vacuum blood tubes on the adapter are removed when the centrifuge works, and the capping-off efficiency is high, so that the adapter is beneficial for the vacuum blood tube of each brand, and has high applicability.

Description

A kind of vacuum test tube takes off the adapter that covers centrifuge

Technical field

The utility model belongs to the laboratory centrifuge accessory, is specifically related to a kind of vacuum test tube and takes off the adapter that covers centrifuge.

Background technology

Medical institutions generally take a blood sample and separating blood constituents with vacuum test tube.After blood processing is intact, must the pipe lid of vacuum test tube be thrown off from body.Because each medical institutions particularly large hospital use the amount of vacuum test tube very big every day, the workload of separate vacuum heparin tube pipe lid is also bigger.Vacuum test tube take off lid except with the manual work, also have the centrifuge that utilizes band to take off cover function or the cover extirpation machine of special use to take off lid.The vacuum test tube of each tame hospital, Blood Center use is produced of a great variety, standard disunity by different vendor at present.Use common on the market taking off automatically to cover the centrifuge separation and take off lid; Taking off the rate of lid depends on the plug in the pipe lid and manages the adhesion between the lid; The heparin tube that is combined takes off the rate of lid and reaches 100%; The rate of lid of taking off in conjunction with bad is lower than 50%, because the combination between plug and the pipe lid is bad, plug receives action of centrifugal force and can separate with the pipe lid when centrifugal.Therefore, this type centrifuge is relatively poor to the applicability of vacuum test tube.As use special-purpose cover extirpation machine to take off lid, and though can guarantee to take off the rate of lid, cost is expensive, can not centrifugally cover disposable completion with taking off, efficient is on the low side, increases infection risk.

The utility model content

The purpose of the utility model is to provide a kind of adaptability good, takes off to cover the high vacuum test tube of efficient and take off the adapter that covers centrifuge.

The technical scheme that realizes the utility model purpose is: vacuum test tube takes off the adapter that covers centrifuge and comprises a body; Body is provided with some through holes; Through hole is made up of two sections of the large and small aperture that adapts with the pipe of vacuum test tube lid and body respectively; The small-bore Duan Chu that is positioned at through hole on the body is provided with a slot vertical with through hole, is provided with a clamp in the slot, and the slot bottom is provided with elastomeric element and cooperates with clamp; Said clamp be provided with said through hole on the perforation that adapts of small-bore section.

Said body is formed through the screw assembly by upper plate and lower plate, and said slot is between upper plate and lower plate, and said clamp is provided with mounting hole and said screw fit.

Perforation on the said clamp is stacked to constitute by large and small two different circular holes, and wherein the diameter of big hole is greater than the body of vacuum test tube, the somewhat larger in diameter of small sircle hole in or equal the heparin tube body.

This adapter is with flexible clamp owing in body, being provided with, and when centrifuge is worked, can slough the pipe lid of all vacuum test tubes on the adapter, takes off and covers the efficient height, and go for the heparin tube of different brands, and applicability is good.

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

The specific embodiment

Embodiment 1

See Fig. 1-3; Vacuum test tube takes off the adapter that covers centrifuge and comprises one 1, and body 1 is provided with some through holes, and through hole is made up of two

section

2,3 of the large and small aperture that adapts with the pipe of vacuum test tube lid b and body a respectively; Small-bore section 3 places that are positioned at through hole on the body 1 are provided with a slot vertical with through hole; Be provided with a clamp 5 in the slot, the slot bottom is provided with elastomeric element 4 and cooperates with clamp, and elastomeric element 4 adopts spring (also can adopt shell fragment); Said clamp 5 be provided with said through hole on the perforation 6 that adapts of small-bore section 3.

The utility model is contained on the centrifuge and uses, and user mode is seen Fig. 3.

Place heparin tube: firmly pin clamp 5; Clamp 5 is moved to elastomeric element 4 one ends, and the through hole on perforation on the clamp 6 and body inserts the through hole on the body at once with vacuum test tube; Pipe covers the large aperture section 2 that b is arranged in through hole, and body a passes the small-bore section 3 of through hole; All heparin tubes unclamp clamp 5 after placing and finishing, and clamp 5 is under the active force of elastomeric element 4, and block card plate 5 limits it up to the body a of heparin tube and moves to moving in the other direction, at this moment, and clamp 5 chucking heparin tube body a.

Take off the process of lid: after centrifuge started, heparin tube received very big centrifugal force; Do not support because of body a bottom, body a covers b with pipe under centrifugal action separates, and body a falls clamp below 5 in the position, and clamp 5 no longer acts on body a; Pipe covers b and receives centrifugal force equally at this moment, and because of being stopped that by the small-bore section 3 of through hole its position does not change, body a covers b with pipe to be separated; When body a moves to its mouth of pipe when breaking away from the active position of clamp 5 along the direction of arrow, clamp 5 will be stuck in to manage under the effect of elastomeric element 4 and cover on the stopper rod c1 of plug in the b; When part pipe cover plug in the b under centrifugal action, cover b with pipe and break away from, at this moment the chock plug c of plug will be blocked and can not continue the whereabouts by the hole wall 601 of perforation 6 on the clamp 5, and lid is taken off in realization.

Embodiment 2

See Fig. 4-7; In the present embodiment; Said body 1 is formed through screw 7 assemblies by upper plate 101 and lower plate 102; The said slot that holds clamp 5 is between upper plate 101 and lower plate 102, and said clamp 5 is provided with mounting hole 8 and cooperates with said screw 7 and play the position-limiting action of clamp 5 when moving; Perforation 6 on the clamp 5 is stacked to constitute by large and small different two circular holes 602,603, and wherein the diameter of big hole 602 is greater than the body a of vacuum test tube, the somewhat larger in diameter of small sircle hole 603 in or equal heparin tube body a, elastomeric element 4 adopts block rubbers.
