Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
The embodiment of the utility model provides a:
as shown in figures 1-5, the device for separating substances with high extraction rate and high transfer rate comprises a cup body 1, wherein the cup body 1 is cylindrical in shape and is internally provided with a circular cavity. The bottom of the cup body is fixed with a filter membrane 2, the bottom end of the cup body is provided with an annular groove 5 in the circumferential direction for fixing the outer edge of the filter membrane 2, and the filter membrane 2 and the outer edge are fixed by welding. The cup body and the filter membrane are both made of PC material or other high molecular polymers such as PE.
The bottom of the cup body 1 is provided with a supporting plate 4 above the filter membrane 2, the periphery of the supporting plate 4 is fixed with the inner wall of the cup body 1, the supporting plate 4 is provided with a plurality of through holes 41, the supporting plate 4 is a circular plate, and the through holes are circular holes. The aperture of the through hole may be slightly larger, since it does not filter the bacteria (for example, detecting bacteria) in the sample liquid, the separation of the bacteria from the sample liquid depends on the filter membrane, and the through hole can allow the sample liquid outside the bacteria to pass through. In this embodiment, the support plate mainly serves as a reinforcement to prevent the filter membrane from being damaged when a negative pressure is formed in the cup.
A sponge layer 3 is filled between the filter membrane 2 and the support plate 4, and the upper side and the lower side of the sponge layer 3 are close to the support plate and the filter membrane. A cavity for placing the sponge layer is formed between the annular bulge on the inner side of the annular groove and the lower side surface of the supporting plate. The sponge layer 3 is clamped between the filter membrane 2 and the support plate 4, is in a movable state and does not need to be particularly fixed, is in a disc shape matched with the cavity, is thinner and transparent, and is provided with a through hole, so that an unwanted sample can pass through.
The inner annular bulge 12 of the annular groove 5 is higher than the outer annular bulge 11 of the annular groove, the two annular bulges surround the annular groove, and the inner annular bulge 12 extends downwards to protrude out of the outer annular bulge 11. The edge of the filter membrane 2 is a fixed part 21, the circular area in the middle of the filter membrane 2 is a filter part 22, the filter part 22 is lower than the bottom end of the periphery of the cup body, and the inner side annular bulge extends downwards, so that the structural design is more beneficial to the filter membrane to contact with sample liquid and transfer separated bacteria (or cells and the like) onto a slide.
In this embodiment, the filter membrane 2 is a polycarbonate filter membrane, and the size of the filter pores is selected according to actual requirements. The pore size is typically from 1 micron to tens of microns. For example, if the device of the present invention is used to separate 5 microns of bacteria, a filter membrane with a pore size of 4 microns can be selected, and the bacteria of this type cannot pass through the filter membrane and are adsorbed on the filter membrane. More bacteria of the type can be adsorbed by negative pressure treatment in the cup body. When the cup other end sealed high negative pressure suction, the filter membrane receives powerful suction, has penetrating sponge layer 3 buffering, backup pad 4 to support because of the upside, and rupture of membranes or the damaged condition of membrane can not appear in the filter membrane in certain big small bore diameter and take place. After separation and adsorption of samples such as bacteria or cells, when smear transfer is performed on the samples adsorbed on the membrane by slide imprinting, more samples are transferred to the slide from the adsorption on the membrane due to the fact that the bottom of the sample is provided with the elastic transparent sponge layer.
In other embodiments, the sponge layer can be replaced by an elastic buffer layer made of a sponge-like material.
In other embodiments, the through holes on the supporting plate are not limited to through holes, but may have other shapes, such as rectangular holes.
In other embodiments, the cup body may be square or other shapes, and is not limited to a cylindrical shape.
