Description
[technical field]
The utility model relates to technical field of medical instruments, specifically a kind of being used to the centrifuge rotor adapter that takes off lid arrangement.
[background technology]
As everyone knows, clinical examination is the important means that medical institutions carry out medical diagnosis on disease or health examination.As the most frequently used blood testing inspection, use vacuum test tube or other blood collecting containers to gather the blood of human body sample, then censorship.Assay step generally is that medical personnel use vacuum test tube or other blood collecting containers that the blood of gathering is put into blood sampling test tube, on test tube labelled cover concentrate behind stopper or the skull deliver to the laboratory be placed on carry out in the centrifuge centrifugal, the main component of blood can be come out the visible component of blood etc. through centrifugal in centrifuge with serum or plasma separation, by the lid of manually opening vacuum test tube or other blood sampling test tubes one by one, draw serum then or blood plasma is chemically examined.
Existing this assay step not only has deficiencies such as troublesome poeration, workload be big, and manually to uncap to the laboratory personnel be the work that part is extremely arduous and have certain risk, accidentally just be easy to occur the blood phenomenon that leaks when uncapping, cause that sample is lost, contaminated environment, also easily cause virus, bacterium in the nosocomial infection phenomenon.
In addition, abroad be to finish the unified work of uncapping at present in medical assay step by the automatic lid closing/opening device, though this has alleviated the arduous of laboratory personnel, it has shortcomings such as cost height, complex procedures.
[summary of the invention]
The purpose of this utility model provides a kind of being used to the centrifuge rotor adapter that takes off lid arrangement, not only alleviated the arduous of laboratory personnel, and operation is very easy, operating efficiency improves greatly.Thereby the principle of this adapter is the centrifugal force that utilizes centrifuge rotor to rotate at a high speed to be produced separates the pipe lid of heparin tube automatically and reaches the purpose of taking off lid automatically with body.
Design a kind of being used to for achieving the above object with the centrifuge rotor adapter that takes off lid arrangement, described adapter is a porous three dimensional structure, inside is provided with a plurality of blind cylindrical hole, the blind hole upper end open, described blind hole is by the upper end, hypomere is formed, described blind hole upper-end inner diameter is big and the hypomere internal diameter is less, the blind hole upper-end inner diameter is slightly larger than heparin tube pipe lid external diameter, blind hole upper end height covers highly quite with the heparin tube pipe or is lower slightly, blind hole hypomere internal diameter is slightly larger than the heparin tube external diameter, blind hole hypomere aspect ratio heparin tube is slightly long, and a gap is arranged between the bottom of the bottom of heparin tube and described adapter blind hole.
Described clearance distance is greater than the height of described heparin tube pipe lid.
Described adapter is made up of the multilayer adapter main body, is connected by detachable between every layer of adapter main body.
Described adapter is made up of top layer adapter main body, middle level adapter main body and bottom adapter main body.
The bottom of the blind hole on the described bottom adapter main body is provided with pad.
The utlity model has simple in structure, novel, be placed on the heparin tube in the adapter, because skull is stuck in the lid groove of blind hole mouth, and the gap is left with the heparin tube bottom in the blind hole bottom, under the centrifugal rotation of centrifuge, the centrifugal action that produces because of acceleration of gravity is opened the pipe lid of heparin tube automatically, not only alleviates medical personnel's labour intensity like this, and operation is very easy, operating efficiency improves greatly, can also use for the heparin tube of differing heights; In addition, the utility model is made simple, and cost is low, and is safe, preserves good medical environment, avoids advantage such as cross infection in hospital, is worthy of popularization.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a profile of the present utility model;
Fig. 3 is specific embodiment of the utility model figure.
Among the figure: 1 be the top layer adapter main body, 2 for the middle level adapter main body, 3 for the bottom adapter main body, 4 for heparin tube pipe lid, 5 for the blind hole upper end, 6 for heparin tube, 7 for the blind hole hypomere, 8 for gap, 9 be pad.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
According to Fig. 1, shown in Figure 2, the utility model adapter is a porous three dimensional structure, inside is provided with a plurality of blind cylindrical hole, the blind hole upper end open, described blind hole is made up of upper end, hypomere, the blind hole upper-end inner diameter is big and the hypomere internal diameter is less, and the blind hole upper-end inner diameter is slightly larger than heparin tube pipe lid external diameter, and height and heparin tube pipe lid are highly quite or lower slightly; Blind hole hypomere internal diameter is slightly larger than the heparin tube external diameter, and the aspect ratio heparin tube is slightly long, and heparin tube is packed into and just in time is suspended in the blind hole of adapter after the blind hole like this.Like this do not have centrifugal before, a gap is arranged between the bottom of the bottom of heparin tube and described adapter blind hole.After centrifuge starts, centrifuge rotor rotates at a high speed, owing in the heparin tube blood preparation is housed, under the gravity effect, the body of heparin tube is to the cecum operation of adapter endoporus, and the pipe of heparin tube lid is bigger than the internal diameter of hypomere blind pipe, can be blocked, and pipe covers to separate with body and reaches the purpose of taking off lid automatically like this.Excessive for preventing centrifugal force, taking off the bottom that lid back heparin tube body can be threaded to blind pipe, adapter base is provided with elastic body shims such as rubber or silica gel, to break at the bottom of the pipe that prevents heparin tube.
Because the different employed vacuum test tubes of the project of chemical examination or other blood collecting containers have different size (being the branch of length thickness).The clinical examination of medical institutions is now finished by self-reacting device mostly, the size of employed heparin tube is also mostly to be comparatively unified in the world several specifications, though these heparin tube external diameters are generally comparatively unified but length can be different, so described adapter can be made up of the multilayer adapter main body, be connected by detachable between every layer of adapter main body, like this can be according to the number of plies of the length adjustment adapter of heparin tube, to adapt to the heparin tube needs of different length.
Adapter adopts the multilayer design also can be conveniently the lid that takes off behind the lid to be taken out easily, centrifugally finishes the back as long as the superiors of adapter are taken out, and the lid after breaking away from can be taken out together with the adapter upper strata to discard.
