Abstract

The utility model relates to the field of medical appliances, in particular to a device for rapidly collecting micro serum samples, which comprises a bottle (3) with a bottle opening. A bottle nozzle (1) is arranged on the bottle opening, the rear end of the bottle nozzle (1) is connected with the bottle opening, and a support is arranged at the rear end of the bottle nozzle (1) and provided with a micropore filter membrane (2) for covering the bottle opening. The device further comprises a bottle cap (4) with a protecting function. The device for rapidly collecting the micro serum samples is simple in structure, convenient and accurate in operation and easy to be carried, provides a feasible basis for detecting techniques of micro and ultramicro laboratories in the future, and develops new designs.

Description

Be used for collecting fast the device of micro-blood serum sample

Technical field

The utility model relates to the medical instruments field, is specifically related to a kind of device that is used for collecting fast micro-blood serum sample.

Background technology

When carrying out various experiments detections and analyzing as sample with serum both at home and abroad at present, all be just can carry out various experiments detections after adopting the vein haemospasia separation of serum, because this traditional sampling method is loaded down with trivial details, blood sampling volume is many, the separation of serum duration, uneconomical, especially the sampling to microcirculation disorder and infant patient is very difficult, and influences the accuracy of experimental result.In sampling process, use disposable syringe in addition, can pollute to environment, be unfavorable for basic unit, rural area, army and infant's health screening in case deal with improperly.

The utility model content

Collect the deficiency of serum in order to overcome prior art, the utility model aims to provide a kind of device that can be used for collecting fast micro-blood serum sample fast, accurately, easily.

To achieve these goals, the technical scheme that the utility model adopted is:

A kind of device that is used for collecting fast micro-blood serum sample comprises the bottle of being with bottleneck, and bottle neck is housed on the bottleneck, and the rear end of bottle neck is connected with bottleneck, and the rear end of bottle neck is provided with support, and support is provided with the miillpore filter that covers bottleneck.

A kind of device that is used for collecting fast micro-blood serum sample also comprises the bottle cap that is used to shield.

Below the utility model is done further detailed elaboration:

The utility model is miillpore filter to be cut into suitable size put into the filter membrane plastic stent, and is hot-forming, constitutes the device that is used for collecting fast micro-blood serum sample that cell filters with the drop bottle body.

The aperture of the miillpore filter that the utility model uses is 3 μ m-5 μ m, can stop cell to filter, the miillpore filter that can allow micromolecule class material (as materials such as virus, antigen, antibody) penetrate again by the washed corpuscles that is used for of filter membrane, and is collected serum.

The device that is used for collecting fast micro-blood serum sample of the present utility model prepares a certain amount of micro-serum, according to the comparative measurements of its multiple proportions relation and medicinal box special to 10 parts of former times of blood serum samples such as HAV, HIV, Anti-HCV, HBsAg, learn the equal P of comparative analysis＞0.05 no significant difference by statistics, the rate that conforms to reaches 100%.Trace is referred to that blood carries out with microscope that red blood cell is observed and reaches 100% with the classic method collection serum rate that relatively conforms to.(concrete correlation data is referring to embodiment)

Advantage of the present utility model is:

The device that is used for collecting fast micro-blood serum sample of the present utility model, simple in structure, easy to operate accurately, carry easily, for trace, ultramicron laboratory detection technology from now on provide feasible foundation, expand new thinking.

Embodiment

In conjunction with the accompanying drawings embodiment of the present utility model is described further:

As shown in Figure 1, a kind of device that is used for collecting fast micro-blood serum sample comprises the bottle 3 of being with bottleneck, it is characterized in that bottle neck 1 is housed on the bottleneck, and the rear end of bottle neck 1 is connected with bottleneck, and the rear end of bottle neck 1 is provided with support, and support is provided with the miillpore filter 2 that covers bottleneck.The structure of miillpore filter 2 as shown in Figure 2, wherein Fig. 2 (a) and Fig. 2 (c) are the miillpore filter sectional view of different size, Fig. 2 (b) is the miillpore filter side view of Fig. 2 (a), Fig. 2 (d) is the miillpore filter side view of Fig. 2 (c).

Get 200 μ L blood samples with disposable sterilized blood collection needles, dilute with 200 μ L blood dilution liquids, the micro-blood serum sample device of quick collection that is used for of the present utility model filters the serum that collection obtains about 320 μ L, with 10 parts of these serum after collecting, compare experiment by ten duplicate samples respectively with classic method collection serum, with microscopic examination red blood cell and HAV, HIV, Anti-HCV, the comparative measurements of HbsAg (making micro-medicine box and conventional medicine box by oneself), its result learns the equal P of comparative analysis＞0.05 by statistics, the difference nonsignificance, coincidence rate reaches 100%, the results are shown in Table 1-5.
