Description

Technical Field

[0001] The utility model belongs to the field of biochemical staining equipment, and in particular relates to a full-automatic Gram staining machine. Background Art

[0002] The staining machine is mainly used in the pre-processing stage of specimens in the laboratory. After the specimens are centrifuged, they need to be stained so that they can be clearly seen under the microscope. During the staining process, the slides need to be placed on the slide support table, then stained, and finally washed for use;

[0003] For example, the Chinese utility model patent application number is CN202021996616.6, and the patent name is a fully automatic pathological section staining system, which specifically discloses that a certain amount of washing liquid is dripped through the reagent cleaning unit 61, soaked for a certain period of time, and the slide is blown and washed. After repeating the dripping, soaking, and blowing and washing related operations, the slide sample is heated to the required temperature through the heating unit 21, a certain amount of post-hybridization washing liquid is dripped, soaked for a certain period of time, and the slide is blown and washed. After repeating the dripping, soaking, and blowing and washing several times, the slide sample is heated to the required temperature, a certain amount of deionized water is dripped, soaked for a certain period of time, and the slide is blown and washed. At this time, the slide sample maintains the required temperature, and the slide is baked for a certain period of time to complete the washing process. In this design, during the process of washing the slide, the setting position of the slide is fixed and immovable, and it is a structural design embedded in the workbench. Therefore, it is necessary to cooperate with the processes such as soaking, blowing and washing, and its design and use costs are high;

[0004] In addition, there is also a groove design on the slide support table for drainage, so that waste water can be discharged smoothly during the cleaning process of the slide. However, due to the long-term use of the groove structure design, the internal cleaning is more troublesome, time-consuming, and the cleaning effect is not good. If the cleaning is not thorough, it is easy to contaminate the slide and affect the staining effect.

For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0026] In order to solve the problems existing in the prior art, the present application provides a fully automatic Gram staining machine, including a work surface, a Y-axis motion component 2 is fixedly installed on the top of the work surface, an X-axis motion component 1 is fixedly installed on the sliding end of the Y-axis motion component 2, a Z-axis motion component 3 is fixedly installed on the sliding end of the X-axis motion component 1, and a plurality of dyeing liquid TIP heads and a conduit 4 are arranged on the sliding end of the Z-axis motion component 3, the conduit 4 is connected to the main pipe of the three-way valve, and the two branches of the three-way valve are respectively connected to the water supply pipe and the air supply pipe 29, and the water supply pipe and the air supply pipe 29 are respectively connected to the water source and the air source;

[0027] A waste liquid tank 7 is fixedly installed on the top of the work table and along the running track direction of the X-axis motion component 1. The top bearing of the waste liquid tank 7 is connected to a load-bearing bracket 8. A plurality of placement stations 10 are arranged in sequence on the top of the load-bearing bracket 8 along the running track direction of the X-axis motion component 1. A glass slide 9 is arranged inside the placement station 10. A rotating component 12 is fixedly installed on the sliding end of the Y-axis motion component 2. The output shaft of the rotating component 12 is fixedly installed with the load-bearing bracket 8. A water outlet 11 is arranged at one end of the placement station 10. The load-bearing bracket 8 is rotated by the rotating component 12 so that the water outlet 11 faces the waste liquid tank 7.

[0028] In a preferred embodiment of the present invention, further, multiple dyeing liquid TIP heads include: A liquid TIP head 5, B liquid TIP head 6, C liquid TIP head 30, and D liquid TIP head 31. The A liquid TIP head 5, the B liquid TIP head 6, the C liquid TIP head 30, and the D liquid TIP head 31 are respectively connected to the A dyeing liquid tube, the B dyeing liquid tube, the C dyeing liquid tube, and the D dyeing liquid tube, and the A dyeing liquid tube, the B dyeing liquid tube, the C dyeing liquid tube, and the D dyeing liquid tube are respectively connected to the A pump body, the B pump body, the C pump body, and the D pump body.

[0029] In a preferred embodiment of the present invention, further, it includes a housing and an operation panel, the operation panel is a touch panel, and a vertical baffle 28 is arranged inside the waste liquid tank 7 and near the X-axis motion component 1.

[0030] Specifically, the present embodiment takes the dyeing machine with four groups of dyeing liquid TIP heads as an example. Since the Z-axis motion component 3 is provided with a conduit 4, an A liquid TIP head 5, a B liquid TIP head 6, a C liquid TIP head 30, and a D liquid TIP head 31, the connecting end of the conduit 4 is respectively connected to the air supply pipe 29 and the liquid supply pipe through a tee, and the branch pipes of the tee are respectively connected to the air supply pipe 29 and the liquid supply pipe, the air supply pipe 29 is connected to the air pump, and the liquid supply pipe is connected to the clean water pump. The conduit 4 is connected to the air circuit and the water circuit at the same time. When it is necessary to blow air to the slide glass 9 (including mixing and air drying after dyeing and air drying after cleaning the slide glass 9), the air circuit is opened, and when it is necessary to clean the slide glass 9, the water circuit is opened, so that one tube is used for two purposes, the integration is high, and the design is more compact. The P head 5, the B liquid TIP head 6, the C liquid TIP head 30, and the D liquid TIP head 31 are connected to the A dyeing liquid tube, the B dyeing liquid tube, the C dyeing liquid tube, and the D dyeing liquid tube, respectively, so that it is convenient to dye the B dyeing liquid after dyeing the A dyeing liquid, then dye the C dyeing liquid, and finally dye the D dyeing liquid. The four dyeing liquid tubes ABCD work independently, and the amount of the dyeing liquid can be controlled more accurately; because a waste liquid tank 7 is provided between the Y-axis motion component 2, the opening ends of the conduit 4, the air supply pipe 29, the A liquid TIP head 5, the B liquid TIP head 6, the C liquid TIP head 30, and the D liquid TIP head 31 are all facing the waste liquid tank 7, and a bearing bracket 8 is provided above the waste liquid tank 7, and a plurality of placement stations 10 for placing slides 9 are arranged side by side on the bearing bracket 8;

[0031] When staining is required, a glass slide 9 is first placed at the placement station 10 of the support bracket 8. The waste liquid tank 7 is used to collect waste liquid, mainly including waste liquid for cleaning the four staining liquid tubes ABCD and waste liquid for cleaning the glass slide 9. The waste liquid tank 7 can be connected to a waste liquid pipe, and the waste liquid pipe is connected to a waste liquid pump to facilitate the timely discharge of waste liquid in the waste liquid tank 7;

[0032] Since the placement station 10 includes a water outlet 11, a rotating component 12 is provided on the Y-axis motion component 2, and the rotating component 12 drives the supporting bracket 8 to rotate, and the rotation axis of the supporting bracket 8 is parallel to the length direction of the X-axis motion component 1, then when dyeing is required, the rotating component 12 drives the supporting bracket 8 to be in a horizontal state or tending to be in a horizontal state, which is a dyeing station state and is convenient for dyeing operations. When the rotating component 12 drives the supporting bracket 8 to rotate to an inclined state, the water outlet 11 is inclined toward the waste liquid tank 7. When cleaning is completed, the rotating component 12 drives the supporting bracket 8 to rotate to a state where the water outlet 11 is inclined toward the waste liquid tank 7, so as to facilitate the flow of water on the slide 9 into the waste liquid tank 7.

[0033] In order to prevent waste liquid from splashing during cleaning and affecting the control components arranged behind the X-axis motion assembly 1, a vertical baffle 28 is provided at the inner end of the waste liquid tank 7, and the vertical baffle 28 is located below the X-axis motion assembly 1.

[0034] It should be noted that in order to save dyeing liquid and prevent the dyeing liquid from settling in the pipeline and clogging the pipeline, the A pump body, the B pump body, the C pump body, and the D pump body can be provided with a reverse suction function, which can recover the A dyeing liquid, the B dyeing liquid, the C dyeing liquid, and the D dyeing liquid from the A liquid TIP head 5, the B liquid TIP head 6, the C liquid TIP head 30, and the D liquid TIP head 31 into the container containing the dyeing reagent, so as to save dyeing liquid and prevent pipeline clogging.

[0035] In order to facilitate the automatic cleaning of dyeing liquid tube A, dyeing liquid tube B, dyeing liquid tube C, and dyeing liquid tube D, dyeing liquid tube A, dyeing liquid tube B, dyeing liquid tube C, and dyeing liquid tube D are also connected to cleaning pumps respectively, and the cleaning pumps are connected to a clean water source.

[0036] This dyeing machine can be applied to Gram staining, and each station can set dyeing parameters separately. The specific dyeing parameters that can be set include ABCD drip volume, ABCD drip flow rate, ABCD drip waiting time, mixing and blowing time, mixing and waiting time, flushing time, air drying time, air drying time and waste liquid extraction time, among which the air drying time and waste liquid extraction time only depend on the station 1 parameter of each dyeing mode. For example, there are twelve placement stations 10 on the supporting bracket 8, and the dyeing parameters can be set separately for the twelve placement stations 10, for example: the drying time of Gram staining station 1 is set to 10 seconds, and the waste liquid extraction time is set to 10 seconds, the drying time of Gram staining station 1 is set to 20 seconds, and the waste liquid extraction time is set to 30 seconds. When performing Gram staining, the drying time and waste liquid extraction time are 10 seconds respectively.

[0037] In summary, this dyeing machine can dye multiple glass slides 9 at one time, and has a unique way of simulating artificial dripping, which saves dye. The use of a large-aperture pipeline tip can prevent the pipeline gun head from being blocked by dye. The structural design is compact and low-cost, and it can dye multiple glass slides 9 at one time. In addition, the operations of mixing, air drying, cleaning of the dyeing pipeline, cleaning of the glass slide 9, air drying after cleaning the glass slide 9, and discharge of waste liquid during the dyeing process are all automated operations, which greatly improves the degree of automation while saving operating space.
