Description

Technical Field

[0001] The utility model relates to the technical field of clinical testing and detection, in particular to a disposable double-concentration counting cell. Background Art

[0002] In clinical testing, specimen counting plays a very important role, and the counting method and counting tools directly determine the accuracy of the counting. For specimens with uniform distribution and consistent sampling volume, all counting methods have little effect on the counting results. However, for specimens that are difficult to take, unevenly distributed, and have a relatively large dilution, it is also very important to have a better counting pool that can obtain more accurate results and avoid missed detections. Utility Model Content

[0003] The utility model is to overcome the above shortcomings in the prior art, and the proposed disposable dual-concentration counting cell is a very good counting tool, especially for specimens with large dilution and semi-quantitative counting detection, which can greatly reduce the occurrence of missed detection.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions: a disposable dual-concentration counting cell, comprising a double-layer structure, comprising a counting cell cover and a counting cell body, which are tightly integrated to form a cavity, i.e., a counting cell. The counting cell comprises two regions: an original concentration counting cell and a concentrated counting cell. A filtrate placement hole is provided at one end of the concentrated counting cell, into which filtrate can be placed. The counting cell cover is provided with a sample loading hole, and the counting cell body is provided with a sample loading sedimentation tank corresponding to the sample loading hole. After the sample is added, large particles in the sample are retained in the sample loading sedimentation tank, and the sample then flows to the original concentration counting cell and the concentrated counting cell, respectively. The filtrate in the filtrate placement hole absorbs the dilution liquid in the sample in the concentrated counting cell, thereby achieving a concentration effect.

[0005] The original concentration counting pool is divided into two depths, one is the original concentration shallow counting pool, and the other is the original concentration deep counting pool. When the sample concentration is relatively high, the original concentration shallow counting pool can achieve detection; when the sample concentration is relatively low, the original concentration deep counting pool can also achieve detection.

[0006] The concentration counting chamber also has two depths: a shallow concentration counting chamber and a deep concentration counting chamber. When the specimen concentration is very low, the dilution solution in the concentration counting chamber is drawn out through the filtrate to concentrate the specimen, thereby increasing the specimen concentration and enabling detection. The depth of the shallow and deep concentration counting chambers is similar to that of the original concentration shallow and deep counting chambers.

[0007] The counting pool cover is provided with a counting pool window corresponding to the positions of the original concentration counting pool and the concentrated counting pool. The counting pool window, the original concentration counting pool and the concentrated counting pool are all designed to be colorless and transparent.

[0008] The original concentration counting pool and the concentrated counting pool are respectively provided with an original concentration counting pool exhaust hole and a concentrated counting pool exhaust hole. When a specimen is added, the exhaust is performed to facilitate the specimen to flow into the counting pool.

[0009] The depth of the sample addition sedimentation tank is deeper than the counting tank. After the sample enters, large particles are precipitated to the bottom of the sample addition sedimentation tank and will not flow into the counting tank.

[0010] The utility model has the following beneficial effects: the traditional counting pool has only one depth and no concentration function, and can only count fixedly. The disposable dual-concentration counting pool, "disposable" can avoid cross contamination between specimens, does not require pipeline connection, will not cause pipeline blockage, and minimizes the instrument's failure rate; "dual concentration" means that the counting pool can directly count the specimen at its original concentration after processing by the instrument; the concentration counting pool can concentrate the specimen processed by the instrument by suction and filtration, thereby improving the detection rate; the "dual concentration" design can detect visible components at the inherent dilution concentration of the instrument, and can also detect visible components due to small sampling volume or over-dilution of a small amount of specimens. At this time, the concentrate in the concentration pool can filter the dilution liquid in the specimen, thereby increasing the concentration of visible components in the counting pool, making it easier to detect and count.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0018] As shown in the figure, the disposable dual-concentration counting cell has a double-layer structure, comprising a counting cell cover 13 and a counting cell body 14. These two elements tightly combine to form a cavity, the counting cell. The counting cell is divided into two areas: an original concentration counting cell and a concentrated counting cell. At one end of the concentrated counting cell is a filtrate placement hole 7, into which filtrate can be placed. The counting cell cover 13 is provided with a sample loading hole 1, and the counting cell body 14 is provided with a sample loading sedimentation tank 4 corresponding to the sample loading hole 1. After the specimen is added, large particles in the specimen are retained in the sample loading sedimentation tank 4. The specimen then flows to the original concentration counting cell and the concentrated counting cell, respectively. The filtrate in the filtrate placement hole 7 absorbs the dilution liquid from the specimen in the concentrated counting cell, thereby concentrating the specimen.

[0019] The original concentration counting pool is divided into two depths, one is the original concentration shallow counting pool 5, and the other is the original concentration deep counting pool 11. When the sample concentration is relatively high, the original concentration shallow counting pool can achieve detection; when the sample concentration is relatively low, the original concentration deep counting pool can also achieve detection.

[0020] The concentration counting cell is also divided into two depths: a shallow concentration counting cell 6 and a deep concentration counting cell 12. When the specimen concentration is very low, the dilution solution in the concentration counting cell is drawn out through the filtrate to concentrate the specimen, thereby increasing the specimen concentration and enabling detection. The design principles of the shallow and deep concentration counting cells are the same as those of the original shallow and deep concentration counting cells.

[0021] The counting pool cover 13 is provided with a counting pool window 2 corresponding to the positions of the original concentration counting pool and the concentrated counting pool. The counting pool window, the original concentration counting pool and the concentrated counting pool are all designed to be colorless and transparent and made of colorless and transparent materials for easy detection.

[0022] The original concentration counting pool and the concentrated counting pool are respectively provided with an original concentration counting pool exhaust hole 10 and a concentrated counting pool exhaust hole 9. When a specimen is added, the exhaust is performed to facilitate the specimen to flow into the counting pool.

[0023] The counting pool cover 13 and the counting pool body 14 are tightly combined through the columnar piles 3 and the columnar holes 8 which are positioned corresponding to each other.

[0024] The depth of the sample addition sedimentation tank is deeper than the counting tank. After the sample enters, large particles settle to the bottom of the sample addition sedimentation tank and will not flow into the counting tank; the sample after large particle sedimentation flows into the original concentration counting tank and the concentrated counting tank respectively.

[0025] The counting pool area is concave, and the counting pool cover is flat. Both counting pool areas are connected to the sample addition sedimentation tank. The counting pool body and the counting pool cover are tightly combined to form the counting pool.

[0026] The filtrate can be filter paper, which is used to absorb water in the dilution liquid.

[0027] The disposable dual-concentration counting pool is equipped with two counting areas. One counting area is for the specimen with the original concentration. If pathological visible components are found in this area, the test is positive. However, for specimens with low concentration, the concentration of pathological visible components is too low, such as urine specimens (which require centrifugal precipitation and concentration), or stool specimens, the sampling volume is too small, or due to excessive dilution of the instrument, too many pathological visible components are lost during specimen filtration, often resulting in more than half of the specimens being missed. The other counting pool with a concentration function, after adding a specimen with low concentration, the filter on one side of the counting pool automatically absorbs the liquid in the specimen, increasing the concentration of pathological visible components, thereby achieving the effect of concentration. Its advantage is to increase the detection rate, reduce missed detections, and better improve the quality of detection.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
