Description

Specimen processing device

Technical Field

The utility model relates to a medical science detection instrument technical field, concretely relates to sample processing apparatus.

Background

When a Fluorescence In Situ Hybridization (FISH) method is used for detecting the HER2 gene amplification of a tissue specimen, a water bath box is used for carrying out the steps of pretreatment, digestion, cleaning and the like, the conventional operation is that a copulin cup containing the specimen is placed in the water bath box, the copulin cup is kept balanced in the water bath through the self gravity of the copulin cup, the copulin cup is a glass product, the size is large, and the copulin cup can be ensured to have enough gravity to balance the buoyancy of water so as to ensure that the specimen cannot be poured into the water bath. But has the following disadvantages: the container has larger volume, if the amount of the detection sample is small, the waste of pretreatment liquid, enzyme and cleaning liquid can be caused, and the reagent cost is increased; and the copulin cup is a glass product and is easy to break when the water temperature is high, so the copulin cup is made of high-temperature-resistant glass.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the conventional container for detection is bulky, comparatively heavy, if detect with the sample few, will cause the waste of preliminary treatment liquid, enzyme, washing liquid, increase the reagent cost, be not suitable for a small amount of sample detection, the utility model provides a solve the sample processing apparatus of above-mentioned problem.

The utility model discloses a following technical scheme realizes:

the specimen processing device comprises a floating plate and a specimen box, wherein the specimen box is detachably fixed on the floating plate, and the floating plate drives the specimen box to float in the water bath tank; the box body of the specimen box is used for accommodating specimens.

The utility model provides a sample processing device, which is an assembly composed of a floating plate and a box body, and is completely opposite to the design principle of the original container, the utility model fixes the box body on the floating plate, and the whole floating plate and the box body float on the water bath through the buoyancy of the floating plate, thereby ensuring that the part of the box body for containing the sample is immersed in the water; therefore, the material of the floating plate and the box body is not strictly required, and the floating plate and the box body are made of cheap and light materials such as foam and plastic; the box body can also be made into a container with smaller volume, thus being beneficial to saving reagent.

Furthermore, the floating plate is of a foam plate structure, and through holes are formed in the foam plate structure; after one end of the box body in the long axis direction penetrates through the through hole, the outer wall of the box body is connected with the inner wall of the through hole in an interference fit manner.

After the sample is placed in the box body, the bottom end of the box body extends into and penetrates through the through hole, the box body below the liquid level of the sample in the box body is completely embedded into the water bath, the fixation of the box body on the floating plate is realized through the friction and the extrusion effect of the outer wall of the box body and the inner wall of the through hole, the structure is simple, and the manufacturing cost is low. The kickboard can directly adopt the cystosepiment to make, cost greatly reduced, and through-hole department is elasticity extrusion contact with the box body, and when box body outer wall and through-hole inner wall interference fit contact, the foam particle of through-hole department is compressed, and the recovery effort can produce the squeezing action to the box body, and frictional resistance is great.

Furthermore, the box body is of a chamfered platform structure.

The box body adopts a chamfered platform structure, on one hand, each corner plays a limiting role, and the box body is prevented from rotating circumferentially relative to the through hole and is not beneficial to fixation; on the other hand, especially, it makes to hold more sample liquid in the box body, and the holistic weight of box body increases relatively, and both effects of the buoyancy of the holistic weight of box body and kickboard are opposite, easily makes and takes place relative displacement between box body and the kickboard, the utility model discloses a terrace with edge structure of inversion plays limiting displacement to the box body axial, does benefit to the submerged resistance of the relative kickboard of increase box body.

Furthermore, the box body is of an inverted quadrangular frustum pyramid structure, and the angle between the side surface and the bottom surface of the quadrangular frustum pyramid structure is 60-80 degrees.

When the angle between the side surface and the bottom surface of the prismatic table structure is too small, the requirement on the elasticity of the through hole of the floating plate is high.

Further, the specimen box also comprises a box cover, and the box cover covers the open end at the top of the box body in a sealing mode.

The box cover covers the port of the box body, so that the sealing and storing effects are achieved.

Further, be equipped with annular plastic slab on the face under the lid, annular plastic slab and the size and the shape adaptation of the top opening end of box body, annular plastic slab embedding box body top opening end, the lateral wall and the box body opening end inside wall of annular plastic slab compress tightly the contact.

The lid is fixed through the open end in annular plastic slab embedding box body top of lower face, plays sealed and fixed connection effect simultaneously, and processing is convenient, easy operation.

Furthermore, the outer wall of the annular plastic plate is provided with a positioning bulge, and the inner wall of the open end of the box body is provided with a positioning groove matched with the positioning bulge.

In order to enhance the connection strength between the annular plastic plate and the port of the box body, the annular plastic plate is convexly provided with a positioning bulge, and the positioning bulge is embedded into the positioning groove on the inner wall of the open end of the box body in an interference fit manner for fixation.

Further, the outer diameter of the box cover is larger than the maximum outer diameter of the box body.

The external diameter of lid is greater than the design of the biggest external diameter of box body, therefore the lid external diameter can be far away than the through-hole internal diameter, plays final guarantee effect to the box body, prevents that the box body from sinking the submergence and going into in the water bath.

The utility model discloses have following advantage and beneficial effect:
