The detection device comprises an endoscope assembly, a lavage fluid supply module, a recovery module and a control module. Wherein the recovery module is internally provided with an assembly used for adding a fluorescent coloring agent into the recovery liquid, the fluorescent coloring agent is injected into the recovery liquid in the recovery process of the lavage fluid according to needs, and an electromagnetic drive stirring mechanism is combined, so that dynamic and uniform mixing of the dyeing liquid and the lavage fluid is achieved. The control module automatically adjusts the injection amount, the mixing speed and the stirring duration of the coloring agent according to preset parameters or real-time detection data, and the dyeing reaction time in the operation process is remarkably saved.

To ensure the temperature performance of reagents on a slide without causing the sliding of a heat transfer surface caused by vibration, the specimen slide stirring device of the present invention stirs and mixes a buffer solution on a specimen slide on which a specimen is held and a staining reaction reagent required for staining the above-mentioned specimen, by vibrating, is provided with a slide stage that holds the above-mentioned specimen slide, a temperature adjustment section that performs temperature adjustment of the above-mentioned specimen slide, a heat transfer section that transfers heat to the above-mentioned specimen slide in a manner that makes the temperature of the above-mentioned temperature adjustment section and the above-mentioned specimen slide substantially constant, and a lift stage that lifts and lowers the slide holding section, when stirring the above-mentioned buffer solution and the above-mentioned staining reaction reagent, the above-mentioned lift stage is lowered to separate the above-mentioned heat transfer section from a vibration section that vibrates the above-mentioned buffer solution and the above-mentioned staining reaction reagent before the above-mentioned buffer solution and the above-mentioned staining reaction reagent are vibrated, and the above-mentioned lift stage is raised to bring the above-mentioned heat transfer section into contact with the above-mentioned vibration section when heat transfer is performed to the above-mentioned specimen slide via the above-mentioned heat transfer section.

The utility model discloses a sample table and a staining device, belongs to cell staining field, the sample table is characterized in that a choke weir, an end plate and two cofferdams extend from the edge of a shelving plate, the two cofferdams are positioned on two sides of the shelving plate, the two cofferdams are parallel to each other and are perpendicular to the shelving plate, the end plate and the choke weir are respectively positioned at two ends of the shelving plate, the choke weir is perpendicular to the shelving plate, and the end plate is arranged on the shelving plate. The end portions of the cofferdams extend out of the end plates, the shelving plate, the flow blocking weir, the end plates and the two cofferdams jointly form a bearing area of an open structure, the drainage groove is located in the intersection position of the shelving plate and the cofferdams, and the drainage groove extends to the flow blocking weir to enable the flow blocking weir to be disconnected from the cofferdams. Through structural size matching of the cofferdam and the choked flow weir, under the action of surface tension of the reagent, the reagent is restrained in the bearing area without overflowing, a cover film is not needed, and due to the open design of the bearing area, the reagent is in full contact with the atmosphere and does not generate bubbles; no other operation is needed for removing bubbles, and the dyeing reaction process is simplified.

The technical scheme relates to a bronchoalveolar lavage fluid rapid detection method based on a fluorescent dyeing technology and a corresponding detection device, aiming to improve the detection efficiency of alveolar lavage and sampling screening. The detection device comprises an endoscope assembly, a lavage fluid supply module, a recovery module and a control module. The recovery module is provided with a component for adding a fluorescent dyeing agent to the recovery liquid. The fluorescent dyeing agent is injected into the recovery liquid during the recovery process of the lavage fluid as needed, and the dynamic and uniform mixing of the dyeing liquid and the lavage fluid is realized by combining the electromagnetic drive stirring mechanism. The control module automatically adjusts the injection amount, mixing speed and stirring duration of the dyeing agent according to the preset parameters or real-time detection data, which significantly saves the dyeing reaction time in the operation process.

The application discloses a cleaning method for a slide sample dyeing reaction, and belongs to the technical field of improved methods and devices for dyeing tissues or cells on a slide, and comprises the following steps: a plurality of parallel beam-shaped cleaning reagent jet bodies are generated by using a nozzle to perform inclined spraying on the surface of a spraying area of the slide; the height of the nozzle, the distance between the nozzle and the slide, and the spraying angle and speed of the cleaning reagent jet body are adjusted; and a buffer distance is passed through, so that the fluid is collected and distributed to form a waterfall-shaped fluid, the sample is cleaned by flowing through the surface of the sample area, and the residual reagent in the previous step is removed. The application has the advantages of high cleaning efficiency, low cleaning reagent consumption, and low sample loss rate; by adjusting the pressure or the nozzle parameters, different cleaning intensity requirements can be quickly adapted; the structure is simple, the occupied space is small, various installation occasions can be adapted, and the application is suitable for popularization and use.
