Description

Technical Field

[0001] The utility model relates to the technical field of biological tissue processing, and particularly relates to a biological tissue dehydrator. Background Art

[0002] Biological tissue specimens need to be fixed, dehydrated, cleared, and infiltrated with wax before they can be made. At present, biological tissue dehydration devices include a transmission part and a tissue dehydration part. The transmission part includes a liftable boom and a hanging basket connected to the lower end of the boom, while the tissue dehydration part mainly includes several reagent cylinders that can be moved, and reagents for dehydrating biological tissues are placed in the reagent cylinders. When in use, the biological tissue is placed in the hanging basket, and then the hanging basket drives the boom to move downward so that the biological tissue is immersed in the reagent in one of the reagent cylinders and soaked for a certain period of time; after soaking, the boom moves upward above the reagent cylinder, and then the reagent cylinder moves so that the hanging basket is located above the next reagent cylinder. By moving the boom downward, the biological tissue is immersed in this reagent cylinder. After soaking, the boom moves upward to lift the biological tissue out of this reagent cylinder; the cycle is carried out in the above manner so that the biological tissue is soaked in all the reagent cylinders, thus completing the entire dehydration process.

[0003] However, when the biological tissue is soaked in the previous reagent cylinder and transferred to the next reagent cylinder, since the hanging basket and the biological tissue are just lifted out of the reagent in the previous reagent cylinder, a certain amount of reagent will adhere to the surface of the hanging basket and the biological tissue. During the transfer process, the reagent adhering to the surface of the hanging basket and the biological tissue will drip outside the reagent cylinder, causing pollution to the biological tissue dehydration device.

[0021] As Figures 1 to 2 shown, a biological tissue dehydrator includes a base 1, a turntable 2 is arranged on the base 1, and a rotary driving device for driving the turntable 2 to rotate. A plurality of reagent cylinders 3 are arranged on the turntable 2, and the upper ends of the reagent cylinders 3 are open;

[0022] A lifting driving device 4 is arranged on the base 1. The upper end of the lifting driving device 4 is provided with a lifting plate 5. A hanging basket 8 for holding biological tissues is arranged below the lifting plate 5. A first motor 6 for driving the hanging basket 8 to rotate is arranged on the lifting plate 5, and the first motor 6 is connected to the hanging basket 8 through a connecting rod 7;

[0023] The lifting driving device 4 drives the lifting plate 5 to move between a first height position and a second height position; when the lifting plate 5 is at the first height position, the hanging basket 8 is above the reagent cylinder 3; when the lifting plate 5 is at the second height position, the hanging basket 8 extends into one of the reagent cylinders 3.

[0024] When the present utility model is in use, a biological tissue is placed in the hanging basket 8, and the lifting plate 5 is driven to move up and down by the lifting drive device 4, so as to immerse the hanging basket 8 into the reagent tank 3 or lift the hanging basket 8 from the reagent tank 3; the turntable 2 is driven to rotate by the rotation drive device, thereby realizing the movement of the position of the reagent tank 3; when the lifting plate 5 is at the second height position, at this time the hanging basket 8 is completely immersed in the reagent in the reagent tank 3; when the biological tissue is soaked in one of the reagent tanks 3, first the hanging basket 8 is lifted to a height position higher than the reagent liquid level by the lifting drive device 4, and the upper end of the hanging basket 8 is lower than the upper end of the reagent tank 3, so that the hanging basket 8 stays at this height position temporarily, and the hanging basket 8 is driven to rotate by the first motor 6. During the rotation of the hanging basket 8, the reagent attached to the surface of the hanging basket 8 and the biological tissue is thrown out, and the thrown-out reagent still remains in the reagent tank 3; after the hanging basket 8 rotates for a certain time, the first motor 6 stops running, and the lifting drive device 4 drives the lifting plate 5 to move to the first height position. At this time, the hanging basket 8 is completely higher than the reagent tank 3, and then the rotation drive device drives the turntable 2 to rotate by a certain angle and moves the next reagent tank 3 under the hanging basket 8, and then the lifting drive device 4 drives the lifting plate 5 to move to the second height position so that the hanging basket 8 is completely immersed in this reagent tank 3; during the above operation process is cycled until the biological tissue in the hanging basket 8 is soaked in all the reagent tanks 3, and the dehydration treatment of the biological tissue is realized.

[0025] Among them, in this embodiment, a total of six reagent tanks 3 are provided on the turntable 2. The first reagent tank 3 is filled with formalin test solution, and the second to fifth reagent tanks 3 are respectively filled with alcohols with different concentration gradients. The alcohol concentrations in these three reagent tanks 3 are 80%, 90%, 95%, and 100% respectively, and the fifth reagent tank 3 is filled with xylene reagent.

[0026] The lifting drive device 4 is located at the center of the turntable 2. In this embodiment, the lifting drive device 4 is an electric cylinder. The electric cylinder is arranged in the vertical direction.

[0027] A plurality of through holes are provided on the side and bottom of the hanging basket 8.

[0028] The rotation drive device includes a second motor 9 provided on the base 1, and a gear 10 is connected to the output shaft of the second motor 9; the turntable 2 is circular, and a toothed ring is provided on the circumferential direction of the turntable 2, and the gear 10 meshes with the toothed ring. The turntable 2 is driven to rotate by driving the gear 10 to rotate by the second motor 9 and through the cooperation between the gear 10 and the toothed ring.

[0029] A sealing ring 13 corresponding to the reagent cylinder 3 one by one is provided at the lower end of the lifting plate 5; when the lifting plate 5 is at the second height position, the sealing ring 13 on the lifting plate 5 contacts the upper end of the reagent cylinder 3. Since during the dehydration process of biological tissues, alcohol, a volatile reagent, is contained in several of the reagent cylinders 3, if the reagent cylinders 3 are left open for a long time, the reagent will volatilize, resulting in reagent loss. In order to solve the problem of reagent volatilization in the present utility model, when the biological tissue is being soaked, the lifting plate 5 is at the second height position, and the sealing ring 13 on the lifting plate 5 is in sealed contact with the upper end of the reagent cylinder 3, thereby preventing the reagent in the reagent cylinder 3 from volatilizing.

[0030] Preferably, the sealing ring 13 is made of silica gel.

[0031] Further, a wheel frame 11 is provided on the base 1, and a support wheel 12 is rotatably connected to the wheel frame 11. The support wheel 12 contacts the lower end of the turntable 2. The turntable 2 is supported by the support wheel 12, thereby improving the stability of the turntable 2.

[0032] In the present utility model, when the biological tissue completes soaking in the previous reagent cylinder 3 and is transferred to the next reagent cylinder 3, the first motor 6 drives the hanging basket 8 to rotate, so that the reagent attached to the hanging basket 8 and the biological tissue is thrown out, thereby drying the hanging basket 8 and the biological tissue. This avoids the reagent dripping outside the reagent cylinder 3 during the transfer process and causing pollution to the biological tissue dehydrator.

[0033] The present utility model is not limited to the above best embodiment. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to the present application, it falls within the protection scope of the present utility model.
