Abstract

Disclosed is a plate reaction apparatus with automatic separation and transferring for plasma dot-enzyme immunoassay, which is characterized in that the apparatus is composed of a plate shape plasma separator and a hollow reaction box. The center of the plasma separator is the sample-hole which penetrates the plate, and a processing pad is placed in the sample-hole. The reaction box is a hollow box which comprises a cover plate and a base. A penetrating reaction hole with a reaction film stuck on is arranged on one side of the cover plate, while the plasma separator is buttoned in the channel of the cover plate, and the sample hole of the plasma separator covers on the reaction hole. A mobile imbibing pool is provided, which comprises a tank in the reaction box and a handle extending out of the reaction box. The utility model only takes trace peripheral whole blood as the blood sample, automatically finishes the separation and transferring of the plasma, which is simple in operation and without pollution by the waste liquid.

Description

Automatically separate transhipment blood plasma spot enzyme plate for detecting immunity deblocking reaction device

Technical field:

The utility model is to be used for the device that biological sample detects, especially for the spot enzyme immunoassay device of the automatic separating plasma of need micro blood.

Background technology:

Spot enzyme immunoassay device is widely used in the detection of albumen in the blood of human body, virus etc., but classic method just can be used for detecting after needing instrument to isolate blood plasma more, and sampling amount is more, often needs vein to get blood, is difficult for by the patient, and particularly child patient is accepted.Moreover, lower because of the sensitivity of its detection, be not suitable for the detection of low concentration active substance.

Summary of the invention:

Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology weak point, provide a kind of only with trace end slightly whole blood be blood sample, finish separating plasma transhipment, automatic separation transhipment blood plasma spot enzyme plate for detecting immunity deblocking reaction device easy and simple to handle automatically.

The technical scheme that the utility model technical solution problem is adopted is:

Design feature of the present utility model is to be made of the plasma separator of split setting and reaction box; Wherein:

Plasma separator is plate-like, and central authorities are placed with in well and handle pad for connecting the well of its plate;

Reaction box is the box-like body of hollow, is made of cover plate and base, and the territory, a lateral areas of its cover plate is provided with the reacting hole of perforation, is pasted with reaction film on the reacting hole, and plasma separator be located in the draw-in groove of cover plate, and its well covers on the reacting hole;

Portable imbibition pond is set, constitute by pond body that is arranged in reaction box and the handle that stretches to the reaction box outside, the imbibition pond can be on two positions at least through moving, first pond body be positioned at reacting hole under, it two is that the pond body leaves the reacting hole position fully.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model is the mode that adopts vertical transhipment, and its separating plasma, transhipment and relevant reaction all are to finish on same position, and testing process is rapid and simple.

2, the utility model only needs micro whole blood, and reducing the sample use amount can more help promoting the use of.

3, the setting in portable imbibition pond can make testing process not need washing in the utility model, has not only simplified operation, but also the pollution of having avoided waste liquid to bring effectively.

4, clear, the interpretation that helps the result of the whole background of the utility model.

5, the utility model also can be applicable to the detection of low concentration active substance because of its detection sensitivity height.

Number in the figure: 1 plasma separator, 2 reaction boxes, 3 imbibition ponds, 4 wells, 5 are handled pad, 6 cover plates, 7 bases, 8 reacting holes, 9 reaction films, 10 draw-in grooves, 11 pond bodies, 12 handles, 13 stingy hands.

Embodiment:

Referring to accompanying drawing 1, present embodiment is to be made of the plasma separator 1 of split setting and reaction box 2.

Shown in Figure 2, plasma separator 1 is plate-like, and central authorities are placed with in well 4 and handle pad 5 for connecting the well 4 of its plate.

As Fig. 3, shown in Figure 5, reaction box 2 is the box-like body of hollow, is made of cover plate 6 and base 7, the territory, one lateral areas of its cover plate 6 is provided with the reacting hole 8 of perforation, be pasted with reaction film 9 on the reacting hole 8, plasma separator 1 be located in the draw-in groove 10 of cover plate, and its well 4 covers on the reacting hole 8.In concrete the enforcement, reaction film 9 directly sticks on the upper cover plate 6, has sealed waste liquid and has drawn part, makes reacting hole background on every side for of the same colour, reduces the parallax error that visual impact causes, and outward appearance is clean and tidy.

As Fig. 1, shown in Figure 4, portable imbibition pond 3 is set in the present embodiment, constitute by pond body 11 that is arranged in reaction box 2 and the handle 12 that stretches to reaction box 2 outsides, imbibition pond 3 can be on two positions at least through moving, first pond body 11 be positioned at reacting hole 8 under, it two is that pond body 11 leaves reacting hole 8 positions fully.In concrete the use, in pond body 11, should place adsorbed layer with good adsorption properties.

In addition, as shown in Figure 1 and Figure 2,, on the edge of plasma separator 1, a stingy hand 13 that protrudes is arranged for the ease of using.For the ease of hand-held, the profile of reaction box 2 is set to waist shape.Two ends are wide, and it is gradually narrow that the middle part is circular arc.

Operating process:

1, whole blood adds in the well 4, handles the filtration of pad 5 in blood plasma separation vessel 1, and blood plasma infiltrates reaction film 9;

2, utilize stingy hand 13 that plasma separator 1 is taken off from the draw-in groove 10 of reaction box 2, isolated blood plasma carries out compatible reaction on reaction film 9.

3, adsorb by the waste liquid of the adsorbed layer that is arranged in the pond body 11 of placing the absorption bed course under the reacting hole, pull out pond body 11 compatible reaction.

4, in reacting hole 8, splash into developer, and reaction box 2 is seated under the set point of temperature condition reacts, and take out at official hour.

5, push imbibition pond 3, be located at reacting hole 8 under, exhaust developer fast by the adsorbed layers of placing in the pond body 11, enzymatic reaction finishes.
