Abstract

The utility model provides a test tube. The test tube comprises a test tube body, wherein a changed section is formed on the outer surface of the test tube body. The test tube can also comprise a base matched with the test tube by means of disassembly and assembly. The test tube provided by the utility model can be matched with a manipulator or a mechanical clamp of an instrument and can be prevented from sliding off the manipulator or the mechanical clamp; and moreover, due to the different shapes of bases, the same type of test tubes can be applied to different types of instruments.

Description

Test tube

Technical field

The utility model relates to a kind of medicine equipment, relates in particular to a kind of test tube of depositing liquid.

Background technology

At present, its outer wall construction of employed test tube all is smooth and smooth.The event of test tube landing can occur in operating personnel because the test tube surface is too smooth when taking test tube.When operating with self-reacting device, the manipulator of instrument or mechanical gripper also grasp test tube not too easily, need to guarantee that test tube does not come off by extra structure, and this has just increased cost.

The bottom of test tube all is fixing a kind of shape, such as taper shape, hemispherical or a plane.Its adaptability to instrument of different test tube bottom surfaces is very poor, can only adapt to the instrument supporting with its bottom.

The utility model content

For overcoming the deficiencies in the prior art, one of the purpose of this utility model is to provide a kind of test tube that is conducive to self-reacting device manipulator or the crawl of mechanical gripper.Be to realize this purpose, the utility model provides a kind of test tube, comprising: have the test tube body of opening and bottom, at the outer surface of test tube body a changes of section is arranged.

Two of the utility model purpose is to provide a kind of test tube that can change the test tube bottom shape.Be to realize this purpose, the utility model provides a kind of test tube, comprises the test tube base, and described base is fixed together with removable mode and test tube body or test tube tube wall wall extension.

The beneficial effects of the utility model are: 1) owing to have a changes of section on the test tube wall, this changes of section cooperates with manipulator or the mechanical gripper of instrument, manipulator or mechanical gripper can just in time be fastened on the changes of section position, make manipulator or mechanical gripper catch firmly test tube, prevent that test tube from coming off.2) because test tube has the base of combination dismantled and assembled with it, and base can be made different shapes, thereby satisfy different instruments to the requirement of test tube bottom.The same class test tube can be used on the instrument of different model.

The specific embodiment

Below in conjunction with concrete accompanying drawing the utility model is described in detail.These specific embodiments only are limited the enumerating under the utility model spirit, do not get rid of one of ordinary skill in the art prior art and the utility model in conjunction with and other specific embodiments of producing.

Test tube shown in Fig. 1 to 6 comprises test tube body 1, and described test tube body has opening 2 and test tube bottom.Described test tube bottom can be the structures such as cone bowl heart 3, planar shaped 4, taper shape or hemispherical.In one embodiment, when the test tube bottom was the heart of cone bowl, the collected liquid that its small bottom surface can be more concentrated was conducive to depositing and extracting, the rate that reduces the wastage, minimizing sample demand small quantity reagent or sample.Outer surface at the test tube body has a changes of section.Described changes of section can be the forms such as a groove 5 or ledge structure 6.Described changes of section is positioned at the outer surface of test tube, is convenient to the position that manipulator or mechanical gripper are extracted.Test tube can be that glass, plastic or other material are made.Described changes of section is by realizing with the one-time formed technique of body.

This changes of section on the test tube can cooperate with manipulator or the mechanical gripper of instrument, and manipulator or mechanical gripper can be fastened on this changes of section position firmly, prevents that test tube from coming off from manipulator or mechanical gripper.

On the other hand, the changes of section of test tube can also be as the boundary line of bonding strip shape code.For example, operating personnel can only be along the lower limb bonding strip shape code of changes of section.So just guarantee the accuracy of bar code paste position, guaranteed the scanning of instrument to bar code.

In one embodiment, described test tube also comprises a lid 7, and described lid has a capping plug, and this capping plug can closely cooperate with the inner tubal wall of test tube.

In one embodiment, described test tube also comprises the wall extension 8 of test tube tube wall.This wall extension is selected from the one-time formed structure of test tube body or by the mode that machinery cooperates and is assembled on the test tube body.Described test tube wall extension 8 is enclosed in the test tube bottom wherein.The lower limb of wall extension can be a horizontal structure, makes things convenient for the placement of test tube on the experiment desktop.

In one embodiment, described test tube also comprises a test tube base 9.Described base 9 is fixed together with removable mode and test tube, and namely base and test tube body or test tube wall extension are fixed together.For example base directly is sleeved in test tube body or the test tube wall extension.Described base shape can be the various structures such as bowl heart, base plane shape, taper shape or hemispherical.These different structures can satisfy different instruments to the requirement of test tube bottom, so that the test tube of one species can use at different instruments after having changed base.When for example hemispheric base sheath being contained on the test tube that ground is the plane, this test tube can smooth and easy rotation in having the instrument storage chamber of domed bottom.

Test tube described in the utility model can be used for depositing test sample such as blood, urine, nucleic acid extractive etc., also can deposit the used reagent of test reaction etc.

Embodiment 1 has bowl test tube of heart bottom

Test tube comprises that test tube body 1, described test tube body 1 have an opening 2 and bowl heart bottom 3.Test tube wall extension 8 is enclosed in cone bowl heart bottom 3 wherein.This test tube also comprises a test tube base 9, and described base is fixed together with removable mode and test tube wall extension 8.Described base is a hemispheric stopper shape structure.Described test tube also comprises a lid 7, and this lid has capping plug, and this capping plug can closely cooperate with the inner tubal wall of test tube.
