Description

Technical Field

[0001] This utility model relates to the technical field of dehydrators, and in particular to a pollution-preventing sealing device for a fully automatic pathological specimen dehydrator. Background Technology

[0002] A pathological tissue dehydrator is a commonly used device in medical pathology, primarily used to remove water from pathological tissue specimens. In pathological tissue processing, tissues need to be embedded in paraffin to form hard wax blocks, which are required to be cut into micron-sized sections. If water remains in the tissue, paraffin will have difficulty penetrating the intercellular spaces, causing embedding failure. This will make the tissue brittle or structurally damaged during sectioning. Furthermore, pathological diagnosis relies heavily on the clear visualization of cell and tissue structural details under a microscope, and residual water will cause cell swelling and blurred boundaries, obscuring lesion features and affecting diagnostic accuracy.

[0003] Traditional dehydrators often use simple threaded connections between the dehydration cylinder and the cylinder cover, which are not airtight and can easily lead to reagent leakage during the dehydration process. At the same time, external impurities may also enter and contaminate the specimens, posing a risk of cross-contamination. Secondly, there is a lack of exhaust gas treatment mechanisms. The chemical reagents used in the dehydration process, such as alcohol and xylene, are volatile. Traditional equipment lacks effective exhaust gas treatment devices, and harmful gases are directly emitted into the environment, posing a threat to the health of operators and the surrounding environment. Utility Model Content

[0004] The purpose of this invention is to provide a pollution-proof sealing device for a fully automatic pathological specimen dehydrator, in order to solve the problems mentioned in the background art. Traditional dehydrators often use simple threaded connections between the dehydration cylinder and the cylinder cover, which result in insufficient sealing and are prone to reagent leakage during the dehydration process. At the same time, external impurities may also enter and contaminate the specimen, causing a risk of cross-contamination. Furthermore, the lack of an exhaust gas treatment mechanism means that chemical reagents such as alcohol and xylene used in the dehydration process are volatile. Traditional equipment lacks an effective exhaust gas treatment device, and harmful gases are directly emitted into the environment, posing a threat to the health of operators and the surrounding environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic pathological specimen dehydrator anti-contamination sealing device, comprising a base, a collection tank fixedly installed on the left side surface of the base, a tank cover threadedly connected to the upper end of the collection tank, a counterweight base fixedly connected to the upper end of the tank cover, a protective cover fixedly connected to the upper end of the counterweight base, a rotating shaft passing through both ends of the counterweight base, a tray sleeved on the outer ring of the rotating shaft, a drive motor connected to the upper flange of the rotating shaft, a gear fixedly connected to the lower surface of the tray, a second connecting rod fixedly passing through both ends of the gear, and a dehydration mechanism fixedly connected to the lower end of the second connecting rod;

[0006] The dehydration mechanism includes a cylinder cover, a rubber ring, a buckle, a blue cover, a dehydration basket, and a dehydration cylinder. A rubber ring is fixedly installed on the lower surface of the cylinder cover, and a buckle is fixedly installed on the outer ring of the cylinder cover. A blue cover is sleeved on the outer ring of the second connecting rod. A dehydration basket is threaded to the lower end of the blue cover. A dehydration cylinder that fits tightly against the rubber ring is fixedly connected to the lower surface of the cylinder cover. A drain outlet is provided on the lower surface of the dehydration cylinder.

[0007] Preferably, a fixing block is fixedly installed on the upper surface of the base, and a first connecting rod is fixedly installed through both ends of the fixing block. One side of the protective cover is connected to the first connecting rod through the connecting block and forms a rotating structure with the fixing block.

[0008] Preferably, the counterweight base has an embedded metal counterweight block, the bottom of the protective cover adopts a magnetic design, and the cover body is made of transparent acrylic.

[0009] Preferably, the upper surface flange of the protective cover is connected to an air pipe, the lower end of the air pipe is connected to a filter, the right side surface of the filter is connected to an air outlet pipe, and the lower end of the air outlet pipe is connected to an exhaust gas collection pipe.

[0010] Preferably, the filter is provided with a porous adsorption layer composed of coconut shell activated carbon particles.

[0011] Preferably, the drive motor provides power to rotate the large gear, which meshes with nine small gears, thereby causing the small gears to rotate the dehydration basket via the second connecting rod.

[0012] Preferably, the dehydration cylinder and the cylinder cover are connected by snap-fit ​​to form a highly airtight space.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This fully automatic pathological specimen dehydration machine anti-contamination sealing device uses a cylinder cover and dehydration cylinder connected by a snap-fit ​​mechanism, which, together with a rubber ring, forms a highly airtight space. Structurally, it completely blocks the risk of reagent leakage during the dehydration process, while effectively isolating external impurities from intrusion, avoiding cross-contamination of specimens, and significantly improving the cleanliness and safety of pathological specimen processing. Through the porous adsorption layer composed of coconut shell activated carbon particles in the filter, it can efficiently adsorb harmful chemical gases such as alcohol and xylene volatilized during the dehydration process, preventing them from being directly emitted into the environment. This not only protects the health and safety of operators but also reduces pollution to the surrounding environment. The device has a counterweight base with embedded metal counterweight blocks and a magnetic transparent acrylic protective cover, combined with a rotatable connection structure. This solves the problems of poor stability and inconvenient opening and closing of traditional protective covers, while achieving high sealing performance when the protective cover is closed and convenient operation. Moreover, the transparent material allows for real-time observation of the dehydration process, taking into account both functionality and visual monitoring needs. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a fully automatic pathological specimen dehydrator anti-contamination sealing device, including a base 1, a collection tank 2 fixedly installed on the left side surface of the base 1, a tank cover 3 threadedly connected to the upper end of the collection tank 2, a counterweight base 4 fixedly connected to the upper end of the tank cover 3, a protective cover 5 fixedly connected to the upper end of the counterweight base 4, a rotating shaft 12 passing through both ends of the counterweight base 4, a tray 13 sleeved on the outer ring of the rotating shaft 12, a drive motor 14 connected to the upper flange of the rotating shaft 12, a gear 15 fixedly connected to the lower surface of the tray 13, a second connecting rod 16 fixedly passing through both ends of the gear 15, and a dehydration mechanism 17 fixedly connected to the lower end of the second connecting rod 16;

[0021] The dehydration mechanism 17 includes a cylinder cover 1701, a rubber ring 1702, a buckle 1703, a blue cover 1704, a dehydration basket 1705, and a dehydration cylinder 1706. The rubber ring 1702 is fixedly installed on the lower surface of the cylinder cover 1701, and the buckle 1703 is fixedly installed on the outer ring of the cylinder cover 1701. The blue cover 1704 is sleeved on the outer ring of the second connecting rod 16. The lower end of the blue cover 1704 is threadedly connected to the dehydration basket 1705. The dehydration cylinder 1706, which is tightly fitted with the rubber ring 1702, is fixedly connected to the lower surface of the cylinder cover 1701. A drain port 18 is provided on the lower surface of the dehydration cylinder 1706.

[0022] Furthermore, a fixing block 6 is fixedly installed on the upper surface of the base 1. A first connecting rod 7 is fixed through both ends of the fixing block 6. One side of the protective cover 5 is connected to the first connecting rod 7 through the connecting block and forms a rotating structure with the fixing block 6. Through the setting of the first connecting rod 7, the protective cover 5 can be flipped upward to achieve unobstructed opening and closing, which is convenient for loading pathological specimens or maintaining the internal structure of the equipment.

[0023] Furthermore, the counterweight base 4 has an embedded metal counterweight block, and the bottom of the protective cover 5 adopts a magnetic design and the cover body is made of transparent acrylic. Through the setting of the protective cover 5, a high sealing performance is achieved when the protective cover 5 is closed.

[0024] Furthermore, the upper surface flange of the protective cover 5 is connected to an air pipe 8, and the lower end of the air pipe 8 is connected to a filter 9. The right side surface of the filter 9 is connected to an exhaust pipe 10, and the lower end of the exhaust pipe 10 is connected to an exhaust gas collection pipe 11. Through the installation of the exhaust gas collection pipe 11, a complete exhaust gas treatment process is formed to ensure that harmful gases do not leak directly to the outside.

[0025] Furthermore, the filter 9 is equipped with a porous adsorption layer composed of coconut shell activated carbon particles. Through the filter 9, toxic and harmful chemical reagent gases such as alcohol and xylene that are volatilized during the dehydration process can be efficiently adsorbed.

[0026] Furthermore, the drive motor 14 provides power to drive the large gear to rotate. The large gear meshes with nine small gears, which in turn drive the dehydration basket 1705 to rotate via the second connecting rod 16. Through the setting of the gear 15, the function of a single power source driving multiple dehydration baskets is realized, ensuring that each dehydration basket 1705 rotates stably at the same speed, avoiding uneven speed or jamming caused by power dispersion.

[0027] Furthermore, the dehydration cylinder 1706 and the cylinder cover 1701 are connected by a snap fastener 1703 to form a highly airtight space. The snap fastener 1703 is designed to cooperate with the corresponding slot of the dehydration cylinder 1706 to form a quick and firm connection. Compared with the traditional threaded connection, the snap fastener connection does not require rotation alignment, making the operation more convenient. It also applies pressure evenly and stably, ensuring that the sealing surfaces fit tightly.

[0028] Working Principle: This fully automatic pathological specimen dehydrator features a contamination-proof sealing device. First, the protective cover 5, which rotates around the first connecting rod 7, is opened. The pathological specimen is placed into the dehydration basket 1705, and after being secured by the screws on the basket cover 1704, the cylinder cover 1701 is aligned with the dehydration cylinder 1706. The rubber ring 1702 is tightly compressed by the snap-fit ​​1703, forming a highly airtight space between the cylinder cover 1701 and the dehydration cylinder 1706. This isolates external contamination and prevents leakage of reagents such as alcohol and xylene. The drive motor 14 drives the rotating shaft 12, which in turn drives the gear 15 under the tray 13 to rotate. The gear 15 meshes and drives multiple small gears to synchronously drive the dehydration basket 1705 to rotate at a uniform speed through the second connecting rod 16, ensuring that the specimen is evenly stressed in the dehydration tank 1706 and accelerating the replacement of water and reagents. The harmful gases volatilized during the dehydration process enter the filter 9 with built-in coconut shell activated carbon through the air pipe 8 at the top of the protective cover 5. After adsorption and purification, they are discharged into the waste gas collection pipe 11 through the air outlet 10 for centralized treatment. After dehydration is completed, the buckle 1703 is released and the waste liquid is discharged into the collection tank 2 on the left side of the base 1 through the drain outlet 18 below the dehydration tank 1706. The waste liquid collection can be completed by unscrewing the tank cover 3.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
