Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to a tissue processing instrument. Background Technology
[0002] Pathological dehydrators are commonly used tissue processing equipment in pathology departments and research institutions. Their core function is to fix, dehydrate, clear, and paraffin-impregnate diseased tissues, providing high-quality samples for subsequent tissue embedding and staining. During operation, the liquid level in the reagent vials directly affects the tissue processing outcome. Insufficient reagent may lead to incomplete dehydration, incomplete clearing, or uneven paraffin impregnation, thus affecting the quality of pathological sections. Operators need to monitor the reagent level in the vials and replenish reagents promptly to ensure the continuity of the processing and sample quality. Therefore, the liquid level display on the reagent vials of the pathological dehydrator must be clear and easy for operators to observe.
[0003] Traditional pathological dehydrators have a light source behind the reagent bottle. The light shines through the reagent bottle to display the liquid level. The operator observes the liquid level in the reagent bottle from the front. After a period of use, the liquid level display may become unclear due to reagent contamination or dirt adhering to the inner wall of the reagent bottle. Utility Model Content
[0004] The purpose of this application is to address the shortcomings of the prior art by providing a tissue processing instrument that can clearly display the liquid level in the reagent bottle even after prolonged use.
[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:

The side of the second handle facing the open side is provided with a scale line.
[0008] Optionally, there are multiple reagent bottles arranged sequentially along a second direction within the accommodating space. The second direction is horizontal and perpendicular to the first direction. The light source includes a light strip that extends along the second direction to illuminate multiple reagent bottles simultaneously.
[0009] Optionally, the light strip is an RGB light; and / or, a filter is provided below the light strip.
[0010] Optionally, the top of the reagent chamber is divided into a front half and a rear half along a first direction, and the boundary line between the front half and the rear half divides the top of the reagent chamber's containing space equally, with the light source located in the front half.
[0011] Optionally, the reagent bottle includes a first opening and a second opening, the first opening and the second opening being disposed opposite to each other, a cap being used to seal the first opening, and the second opening being detachably connected to the inside of the reagent compartment.

[0016] The beneficial effects of this application include:
[0017] This application provides a tissue processing instrument, including a reagent chamber and a light source, with the light source positioned at the top of the reagent chamber. The reagent chamber contains a reagent bottle, which includes a bottle body for holding a solution. The bottle body has a cap and a first handle at its top. The light source emits light from above, bypassing the cap and the first handle, into the bottle body to illuminate the gas-liquid boundary line within the bottle. This tissue processing instrument has a light source at the top of the reagent chamber, and the light source emits light from above the reagent bottle, bypassing the cap and the first handle, into the bottle body from top to bottom. The light illuminates the gas-liquid boundary line within the bottle body, where gas is above and liquid is below. Due to the different transmittance of gas and liquid, and because the light is emitted from top to bottom, the gas-liquid boundary line within the reagent bottle can be clearly displayed. Furthermore, the longer the reagent is used, the dirtier and more turbid it becomes, and the clearer the gas-liquid boundary line becomes. Even after prolonged use, when the reagent is contaminated or dirt adheres to the inner wall of the reagent bottle, the liquid level within the bottle can still be clearly displayed.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0031] Please refer to Figure 1 This application provides a tissue processing instrument 10, which may be a tissue dehydrator, staining machine, or immunohistochemistry instrument, etc. These instruments share the common feature that they require the use of a solution, which is stored in a reagent bottle 13 placed within a reagent compartment 11. The reagent bottle 13 has graduations on its front side, allowing for clear observation of the solution level within the bottle to determine the remaining solution volume during operation.
[0032] Please refer to the reference. Figure 2The tissue processing instrument 10 includes a reagent chamber 11 and a light source 12, with the light source 12 positioned on top of the reagent chamber 11. The reagent chamber 11 is used to contain a reagent bottle 13, which includes a bottle body 131 for containing a solution. The bottle body 131 has a cap 132 and a first handle 133 on its top. The light source 12 emits light from above, bypassing the cap 132 and the first handle 133, into the bottle body 131 to illuminate the gas-liquid boundary line inside the bottle body 131.
[0033] Specifically, the reagent bottle 13 includes a bottle body 131, a cap 132, and a first handle 133 located on the top of the bottle body 131. The reagent bottle 13 is placed on the bottom surface inside the reagent compartment 11. The reagent bottle 13 stores a solution, and a gas-liquid boundary line is formed between the solution and the air inside the reagent bottle 13. By observing the position of the gas-liquid boundary line, the operator determines whether the reagent bottle 13 needs to be replenished with solution.
[0034] To enable staff to clearly observe the location of the gas-liquid boundary line, this embodiment of the application provides a light source 12 on the top surface inside the reagent compartment 11. At least a portion of the light emitted from the light source 12 can avoid the cap 132 and the first handle 133 and shine downwards into the bottle body 131, thereby illuminating the gas-liquid boundary line inside the bottle body 131. It is understood that at least a portion of the light emitted from the light source 12 can illuminate the area between the cap 132 and the first handle 133, thereby shining into the bottle body 131; it can also illuminate the side of the first handle 133 (the first handle 133 is narrower than the bottle body 131), thereby shining into the bottle body 131; or it can illuminate other areas on the top of the bottle body 131 that avoid the cap 132 and the first handle 133. This embodiment does not limit this.
[0035] The aforementioned tissue processing instrument 10 has a light source 12 installed at the top of the reagent chamber 11. The light source 12 emits light from above the reagent bottle 13, avoiding the cap 132 and the first handle 133, into the bottle body 131 from top to bottom. The light shines on the gas-liquid boundary line inside the bottle body 131, where gas is above and liquid is below. Due to the different light transmittance of gas and liquid, and because the light shines from top to bottom, the gas-liquid boundary line inside the reagent bottle 13 can be clearly displayed. The longer it is used, the dirtier and more turbid the reagent inside the reagent bottle 13 becomes, and the clearer the gas-liquid boundary line becomes. Even after long-term use, if the reagent inside the reagent bottle 13 is contaminated or dirt adheres to the inner wall of the reagent bottle 13, the liquid level inside the reagent bottle 13 can still be clearly displayed.
[0036] Optionally, a receiving space 111 is formed within the reagent compartment 11 for accommodating the reagent bottle 13, which is placed on the bottom surface of the receiving space 111. The front side of the receiving space 111 is an opening 112, through which the reagent bottle 13 is inserted into the receiving space 111 along a first direction. It can be understood that the first direction is a horizontal direction, and preferably, the first direction is also perpendicular to the plane where the opening 112 is located.
[0037] The reagent bottle 13 has a first side facing the opening 112, and the first side is provided with graduation lines for accurately displaying the remaining amount of solution in the reagent bottle 13. The graduation lines face the opening 112 to facilitate the observation of the liquid level by the operator.
[0038] Alternatively, reagent bottle 13 has a first side facing the opening 112, and a second handle 134 is provided on the first side. The operator can hold the second handle 134 to place or remove reagent bottle 13 from the receiving space 111 along the first direction. The second handle 134 is connected to the bottle body 131, allowing the solution in the bottle body 131 to flow into the second handle 134. It can be understood that, based on the principle of communicating vessels, the liquid level in the second handle 134 is the same as the liquid level in the bottle body 131. The side of the second handle 134 facing the opening 112 has graduation lines, allowing the operator to determine the remaining amount of solution in reagent bottle 13 by observing the liquid level in the second handle 134.
[0039] Optionally, there are multiple reagent bottles 13, which are arranged sequentially along a second direction within the receiving space 111. The second direction is horizontal and perpendicular to the first direction. Preferably, the second direction is also parallel to the plane containing the opening 112. The distribution of multiple reagent bottles 13 along the second direction within the receiving space 111 can improve the space utilization of the receiving space 111 and also allow staff to simultaneously observe the liquid level in all reagent bottles 13.
[0040] The light source 12 includes a light strip that extends along a second direction to simultaneously illuminate multiple reagent bottles 13. The light source 12 uses a light strip, which further enhances illumination. Moreover, compared to illuminating each reagent bottle 13 with a single LED, the light strip can illuminate multiple reagent bottles 13 simultaneously, thereby simplifying the structure and installation process of the light source 12 and improving its installation efficiency.
[0041] Optionally, the light strip is an RGB light, and / or a filter is provided below the light strip.
[0042] RGB lights allow for color adjustment, enabling staff to customize the light strips to meet specific needs and provide personalized solutions for clients.
[0043] Multiple LED beads are spaced apart inside the light strip along the second direction. The light emitted from the light strip is formed by the superposition of the light emitted from multiple LED beads. A filter is set in the light-emitting direction of the light strip. Before the light emitted from the light strip is directed to the reagent bottle 13, it is filtered and homogenized by the filter, so that the brightness of the light emitted from the light strip is more uniform and the clarity of the liquid level display in each reagent bottle 13 is consistent or basically consistent.
[0044] Alternatively, please refer to Figure 3 and Figure 4 The top of the receiving space 111 is provided with a receiving groove 113, which extends along the second direction. The side of the receiving space 111 is provided with an installation port 115 corresponding to the position of the receiving groove 113, and the light strip can be inserted into the receiving groove 113 through the installation port 115. The installation of the light strip using the above method is simple and convenient.
[0045] Furthermore, the top of the accommodating space 111 is provided with a mounting member 114. The longitudinal section of the mounting member 114 perpendicular to the second direction is U-shaped. The mounting member 114 and the top of the accommodating space 111 enclose and form an accommodating groove 113. The light strip is placed on the bottom surface inside the mounting member 114. The bottom surface of the mounting member 114 is provided with a light-transmitting opening 1141. The light emitted by the light strip is directed onto the reagent bottle 13 through the light-transmitting opening 1141.
[0046] Optionally, a limiting piece 116 is provided on the outer side of the reagent compartment 11, the limiting piece 116 is positioned corresponding to the mounting port 115, and the limiting piece 116 at least partially covers the mounting port 115 to prevent the light strip from extending out of the reagent compartment 11.
[0047] The limiting piece 116 is detachably connected to the outer side of the reagent compartment 11. After the light strip is installed, the limiting piece 116 is fixed to the reagent compartment 11, blocking the mounting opening 115 and preventing the light strip from extending out of the mounting opening 115, thus limiting the light strip. When it is necessary to remove the light strip, simply remove the limiting piece 116 to expose the mounting opening 115, and then pull the light strip out from the mounting opening 115. The operation is simple and convenient.
[0048] Optionally, please refer to again Figure 1 There are multiple accommodating spaces 111, which are distributed sequentially along a third direction, which is a vertical direction.
[0049] In this way, more reagent bottles 13 can be accommodated in the reagent compartment 11 at the same time. When there are multiple accommodating spaces 111, each accommodating space 111 is equipped with a light source 12 on its top, and the reagent bottles 13 in each accommodating space 111 are arranged in the same way.
[0050] Optionally, please refer to the following: Figure 2The top of the reagent chamber 11 is divided into a front half and a rear half along the first direction. The boundary line between the front half and the rear half divides the top of the reagent chamber 111 containing space evenly. The light source 12 is located in the front half.
[0051] The front half area is located between the opening 112 of the reagent compartment 11 and the rear half area. The area between the cover 132 and the first handle 133 is located below the front half area. The light source 12 is also located in the front half area. In this way, the illumination area of the light source 12 can be closer to the staff. With the brightness of the light source 12 remaining unchanged, the gas-liquid boundary line in the reagent bottle 13 can be displayed more clearly.
[0052] Alternatively, please refer to Figure 3 and Figure 5 The reagent bottle 13 includes a first opening and a second opening 135, which are arranged opposite to each other. The cap 132 is used to seal the first opening, and the second opening 135 is detachably connected to the inside of the reagent compartment 11.
[0053] Both the first opening and the second opening 135 are connected to the bottle body 131. The first opening is used to add solution into the bottle body 131, and after adding, the cap 132 is closed and sealed. The second opening 135 is detachably connected to the inside of the reagent compartment 11. When the second opening 135 is connected to the inside of the reagent compartment 11, in some cases, the solution in the reagent bottle 13 can enter the reaction area of the tissue processing instrument 10 through the second opening 135. For example, when the tissue processing instrument 10 is a tissue dehydrator, the reagent in the reagent bottle 13 can enter the tissue chamber through the second opening 135 to process the sample in the tissue chamber. In other cases, the waste liquid at the reaction area of the tissue processing instrument 10 can also flow back to the reagent bottle 13 through the second opening 135. For example, when the tissue processing instrument 10 is an immunohistochemistry instrument, after the sample is treated by the reagent in the incubation area, the waste liquid needs to be drawn back from the incubation area to the waste liquid bottle through the second opening 135. In this case, the first opening becomes the waste liquid pouring port. When the second opening 135 separates from the inside of the reagent compartment 11, the reagent bottle 13 can be taken out from the reagent compartment 11.
[0054] Optionally, the first handle 133 extends along a first direction, the cap 132 and the first handle 133 are spaced apart along the first direction, and the light source 12 illuminates the bottle 131 from the area between the cap 132 and the first handle 133.
[0055] The first handle 133 extends along the first direction, which allows the reagent bottle 13 to make full use of the space in the reagent compartment 11 in the first direction. At the same time, it also makes the reagent bottle 13 smaller in the second direction, thus accommodating more reagent bottles 13 in the same space. In addition, the extension of the first handle 133 along the first direction also makes it easier for staff to lift the reagent bottle 13 from above when transferring it.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
