Description

Technical Field

[0001] This utility model relates to the field of tissue dehydration machine technology, and in particular to a reagent storage device for a tissue dehydration machine. Background Technology

[0002] Tissue dehydrators are key pieces of equipment in medical clinical laboratories for the dehydration of pathological tissue specimens. They automate processes such as tissue fixation, dehydration, clearing, and paraffin infiltration. Tissue dehydrators require various reagents, each stored in separate containers. All containers are connected to the dehydrator's reagent dispensing system, which delivers different reagents to the dehydration tank according to a programmed procedure. When a container runs low on reagents, it is disconnected from the dispensing system, removed from the dehydrator, replenished with the required amount of reagent, and then reconnected to the dispensing system. However, it is easy for reagent containers to retain excessive amounts of reagent, leading to waste. Utility Model Content

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0031] Reference Figures 1 to 4 As shown, this utility model provides a reagent storage device for a tissue dehydrator.

[0032] The reagent storage device includes a storage compartment 100, an inclined component 200, multiple reagent containers 300, and multiple quick-connect fittings 400.

[0033] The storage compartment 100 has an opening 110 on the front side to facilitate the placement and removal of multiple reagent containers 300 through the opening 110, and an inclined member 200 is provided in the storage compartment 100.

[0034] Multiple reagent containers 300 are arranged sequentially from left to right in the storage compartment 100. An inclined member 200 abuts against all reagent containers 300, causing the bottom surface of all reagent containers 300 to gradually tilt upward from front to back. An infusion tube 310 is arranged inside the reagent container 300. The front end of the infusion tube 310 extends to the bottom of the front end of the reagent container 300, and the rear end of the infusion tube 310 extends to the top of the rear side of the reagent container 300. A quick connector 320 is installed at the rear end of the infusion tube 310, and the quick connector 320 extends out of the outside of the reagent container 300.

[0035] Multiple quick-connectors 400 are arranged sequentially from left to right on the rear wall of the storage compartment 100. Multiple reagent containers 300 are arranged in a one-to-one correspondence with the multiple quick-connectors 400. A quick-connect interface 410 is provided on the front side of the quick-connector 400. The quick-connect interface 410 and the corresponding quick-connect connector 320 can be detachably connected to achieve communication.

[0036] Since all reagent containers 300 abut against the inclined member 200, the bottom surface of each reagent container 300 gradually tilts upward from front to back, causing the residual reagent in the reagent container 300 to gather at the bottom of the front end. Each reagent container 300 is provided with an infusion tube 310 for connecting to the reagent dispensing system. The front end of the infusion tube 310 extends into the bottom of the front end of the reagent container 300, ensuring that the front end of the infusion tube 310 can obtain the residual reagent at the bottom of the front end of the reagent container 300, thereby reducing the amount of residual reagent in the reagent container 300 and reducing waste.

[0037] Furthermore, the quick-connect interface 410 of the quick-connect bracket 400 is used in conjunction with the quick-connect connector 320 of the infusion tube 310 to facilitate the connection of the reagent container 300 to the reagent dispensing system through the corresponding quick-connect bracket 400, making the disassembly and installation of the reagent container 300 more convenient. At the same time, the quick-connect connector 320 and the quick-connect interface 410 help to fix the reagent container 300 and prevent the reagent container 300 from sliding forward due to the tilt of the bottom surface.

[0038] In this embodiment, the reagent storage device includes a storage compartment 100, a tilting member 200, multiple reagent containers 300, multiple quick-connectors 400, multiple position sensors 500, and a protective cover 600.

[0039] The storage compartment 100 has an opening 110 on the front side, and the opening 110 has an openable door (not shown in the figure). The door is a double door with two door leaves. The two door leaves are respectively hinged to the left and right sides of the opening 110. The two door leaves close to the opening 110 to close the opening 110, and the two door leaves open to the left and right sides to open the opening 110.

[0040] The tilting member 200 is located at the bottom of the storage compartment 100, and the top of the tilting member 200 is provided with a support surface 210. The support surface 210 extends to the left and right sides of the storage compartment 100 in the left and right directions, and extends in the front and back directions. The support surface 210 gradually tilts upward from front to back.

[0041] In this embodiment, the angle between the support surface 210 and the horizontal plane is 1°.

[0042] Multiple reagent containers 300 are arranged sequentially from left to right in the storage compartment 100, with the bottom surface of all reagent containers 300 abutting against the support surface 210, so that the bottom surface of all reagent containers 300 gradually tilts upward from front to back.

[0043] In this embodiment, a reagent type label is provided at the front end of the tilting member 200. The reagent type label is such as alcohol, xylene, fixative, purified water, etc. The position of the reagent type label corresponds one-to-one with the position of the reagent container 300, so as to remind the user to place the reagent container 300 corresponding to the reagent type label in the corresponding position.

[0044] Each reagent container 300 is provided with an infusion tube 310 inside. The front end of the infusion tube 310 extends into the bottom of the front end of the reagent container 300, and the rear end of the infusion tube 310 extends towards the top of the rear side of the reagent container 300. A quick connector 320 is provided at the rear end of the infusion tube 310, and the quick connector 320 extends out of the outside of the reagent container 300.

[0045] Multiple quick-connectors 400 are arranged sequentially along the left-right direction on the rear side wall of the storage chamber 100. The positions of the multiple quick-connectors 400 and the multiple reagent containers 300 are one-to-one. Each quick-connector 400 is provided with a quick-connect interface 410 on its front side. The quick-connector 320 of the reagent container 300 is inserted into the corresponding quick-connect interface 410. All quick-connectors 400 are connected to the reagent dispensing system of the tissue dehydrator. The reagent dispensing system delivers the reagents inside the corresponding reagent container 300 to the dehydration tank through the quick-connectors 400.

[0046] The tilt angle of the support surface 210 of the tilting member 200 relative to the horizontal plane, the tilt angle of the axis of the quick connector 320 relative to the horizontal plane, and the tilt angle of the axis of the quick connector 410 relative to the horizontal plane are the same. When the reagent container 300 is pushed from front to back into the storage chamber 100 along the support surface 210, the quick connector 320 can be smoothly inserted into the corresponding quick connector 410, realizing the quick connection between the reagent container 300 and the quick connector 400.

[0047] Each reagent container 300 has two support columns 330 spaced apart from each other. Each support column 330 is formed by the inward indentation of the left and right side walls of the reagent container 300, and the left and right ends of the support column 330 are respectively connected to the left and right side walls of the reagent container 300.

[0048] Since multiple reagent containers 300 need to be placed in the storage chamber 100, the width of the reagent containers 300 in the left-right direction needs to be compressed, resulting in a larger length of the reagent containers 300 in the front-back direction. By using two or more support columns 330 distributed at intervals in the front and back to connect the left and right side walls of the reagent containers 300 together, it helps to maintain the shape of the reagent containers 300 in the left-right direction and avoids outward deformation due to the liquid in the reagent containers 300 squeezing the left and right side walls.

[0049] The infusion tube 310 inside the reagent container 300 abuts against the top of the foremost support column 330, which helps to support the infusion tube 310 and ensures that the front end of the infusion tube 310 extends to the bottom of the front end of the reagent container 300.

[0050] Each reagent container 300 has a groove 340 at the front end of its left and right side walls. The groove 340 is recessed inward so that the user can insert his hand into the groove 340 at the front end of the reagent container 300 and pull the reagent container 300 forward, thus making it easier to separate the quick connector 320 of the reagent container 300 from the quick connector interface 410 of the quick connector seat 400.

[0051] Each reagent container 300 is provided with a handle 350 on its top. After the reagent container 300 is pulled forward and removed using the groove 340, due to the large length of the reagent container 300 in the front-to-back direction, the bottom of the rear side of the reagent container 300 still abuts against the support surface 210 of the inclined member 200 after the handle 350 on the top of the reagent container 300 leaves the storage chamber 100. This allows the user to hold the handle 350 with their other hand and lift the reagent container 300, thus preventing the rear side of the reagent container 300 from falling to the ground due to its large length in the front-to-back direction.

[0052] In this embodiment, because the reagent container 300 has a large length in the front-to-back direction, the left and right sidewalls of the reagent container 300 bear a large actual internal pressure. Therefore, reinforcing ribs 360 are respectively provided on the left and right sidewalls of the reagent container 300, and the reinforcing ribs 360 extend in the front-to-back direction. In this embodiment, two reinforcing ribs 360 are provided on the same sidewall of the reagent container 300, and the two reinforcing ribs 360 are respectively provided on the upper and lower sides of the support column 330. The distribution of the reinforcing ribs 360 and the support column 330 helps to improve the structural strength of the left and right sidewalls of the reagent container 300 and reduce the deformation of the left and right sidewalls of the reagent container 300 due to internal reagent compression.

[0053] In this embodiment, each reagent container 300 is provided with a transparent window 370 on the front side so that the user can observe the remaining amount of reagent inside the reagent container 300 through the transparent window 370. A volume scale is provided on the transparent window 370 so that the user can know the accurate remaining amount of reagent inside the reagent container 300 according to the volume scale.

[0054] In this embodiment, each reagent container 300 is provided with a liquid filling port on the front side of its top. The liquid filling port is provided with a removable cap. After removing the cap, the reagent can be added to the inside of the reagent container 300 through the liquid filling port.

[0055] Multiple position sensors 500 are arranged at intervals along the left and right direction on the rear side wall of the storage compartment 100. The position sensors 500 are photoelectric sensors. The detection areas of the multiple position sensors 500 correspond one-to-one with the positions of the multiple reagent containers 300. When the reagent container 300 is installed in place, the light emitted by the corresponding position sensor 500 is blocked or reflected by the reagent container 300, thereby enabling the position sensor 500 to detect that the reagent container 300 is installed in place.

[0056] The quick-connector 400 is located above the position sensor 500. Since the quick-connect interface 410 of the quick-connector 400 and the quick-connect connector 320 of the reagent container 300 adopt a quick-connect structure, some liquid may leak from the quick-connect interface 410 and the quick-connect connector 320 and drip down. Therefore, a protective cover 600 is provided on the rear side wall of the storage compartment 100. The protective cover 600 covers the top, rear, left and right sides of all position sensors 500. The protective cover 600 can prevent leaked liquid from dripping onto the position sensor 500.

[0057] In some embodiments, the tilting member 200 can take various forms. For example, the tilting member 200 can be a support block extending in a left-right direction, disposed on the rear side of the bottom wall of the storage compartment 100, and abutting against the rear side of the bottom surface of all reagent containers 300, causing the bottom surface of the reagent containers 300 to gradually tilt upward from front to back. Alternatively, a positioning groove can be provided on the rear side of the reagent containers 300, and the tilting member 200 can be disposed on the rear side wall of the storage compartment 100. The tilting member 200 can be inserted into the positioning groove, causing the rear side of the reagent containers 300 to detach upward from the bottom wall of the storage compartment 100, thereby causing the bottom surface of the reagent containers 300 to gradually tilt upward from front to back.

[0058] In some embodiments, the bottom wall inside the reagent container 300 is configured as an inclined surface that gradually slopes upward from front to back. After the reagent container 300 is placed in the storage chamber 100, the reagent inside the reagent container 300 will converge forward along the inclined surface so that the front end of the infusion tube 310 can transport the remaining reagent in the reagent container 300 outward.
