Abstract
Description
Technical Field
[0001] This invention belongs to the field of immunohistochemistry technology, and specifically relates to a liquid storage device suitable for cryogenic immunohistochemistry machines. Background Technology
[0002] Automated immunohistochemical staining equipment requires multiple cleaning cycles during immunohistochemical procedures, using large amounts of cleaning fluid and generating significant waste liquid. This necessitates a device for storing and collecting the fluids used in the process. Current domestic research on immunohistochemical staining equipment primarily focuses on postoperative immunohistochemical pathological diagnosis. These machines are large and expensive, with relatively low requirements for the integration and cost-effectiveness of the fluid storage device. The intraoperative frozen immunohistochemical machine adapted to this system differs significantly from postoperative immunohistochemical equipment; it is smaller and requires a higher degree of integration and cost-effectiveness in its waste liquid storage device.
[0003] Currently, most commercially available small immunohistochemical staining equipment uses photoelectric sensing, ultrasonic level recognition, or float switch level recognition for its liquid storage devices. These methods suffer from low integration, high cost, large size requirements, poor linear display of liquid volume, and the need for additional devices to limit the container's position and determine whether the container is in place. They are not suitable for the requirements of the intraoperative rapid frozen immunohistochemical equipment in this solution. Utility Model Content
[0004] In order to solve the above-mentioned problems in the prior art, this application provides a liquid storage device suitable for cryogenic immunohistochemistry machine to solve the above-mentioned technical defects.
[0005] According to a first aspect of this invention, a liquid storage device suitable for a cryogenic immunohistochemistry machine is provided, comprising a weighing module, a limiting module, and a storage module. The weighing module includes a weighing sensor pad and a weighing sensor. The weighing sensor pad has a limiting groove, and the weighing sensor is mounted above the weighing sensor pad by cooperating with the limiting groove. Through this structure, the weighing sensor is limited by the limiting groove on the weighing sensor pad. The weighing sensor is located at the lower part of the limiting module. The storage module includes a waste liquid tank, a cleaning liquid tank, and a pure water tank. The bottom of the waste liquid tank, the cleaning liquid tank, and the pure water tank are all provided with grooves, and the limiting module connects and cooperates with the grooves. Through this structure, the limiting module limits the bottom of the waste liquid tank, the cleaning liquid tank, and the pure water tank in the storage module.
[0006] In a specific embodiment, the device further includes a gasket mounted on the load end face above the load sensor. This structural arrangement facilitates the separate acquisition of weight data for the waste liquid tank, cleaning liquid tank, and pure water tank, and provides protection for the load sensor.
[0007] In a specific embodiment, the limiting module includes a mounting top plate with a limiting groove that mates with the gasket. The mounting top plate is mounted on the gasket via the limiting groove. This structure allows the mounting top plate to limit the movement of the gasket.
[0008] In a specific embodiment, the grooves on the bottom of the waste liquid tank, cleaning fluid tank, and pure water tank are located on the rear side of the tank bottom, and the length of the grooves is less than the length of the bottom of the waste liquid tank, cleaning fluid tank, and pure water tank. With this structural design, the grooves on the bottom of the waste liquid tank, cleaning fluid tank, and pure water tank serve as limiting grooves, which can limit the movement of the tank bottom in the rear direction.
[0009] In a specific embodiment, the length of the mounting top plate is less than the length of the grooves at the bottom of the waste liquid tank, cleaning liquid tank, and pure water tank. This structural design allows the mounting top plate to be completely fitted into the grooves at the bottom of the tanks.
[0010] In a specific embodiment, the limiting module further includes a left side plate and a right side plate, with fixing plates on the sides of the left and right side plates that mate with the mounting top plate. This structural design facilitates the fixed connection of the fixing plates on the left and right side plates to the mounting top plate.
[0011] In a specific embodiment, limiting plates are provided on the left and right side plates. This structural design restricts the barrel from translating forward.
[0012] In a specific embodiment, the limiting module further includes connecting supports, which are fixedly connected to the fixing plates of the left and right sides of the plate, respectively. With this structural arrangement, the left and right sides of the mounting top plate are fixedly mounted on the left and right sides of the mounting top plate, respectively. The mounting top plate in the limiting module, together with the left and right sides of the plate, forms a convex-shaped structure that can mate with the groove at the bottom of the bucket.
[0013] In a specific embodiment, the left side plate, the mounting top plate, the right side plate, and the connecting support together form a U-shaped structure, which connects and engages with the bottom groove of the liquid storage module. This structural design restricts the tank from shifting laterally.
[0014] In a specific embodiment, the liquid storage module also includes pipes and pipe supports. The pipe supports are mounted on the frame, and the pipes pass through the pipe supports. Through this structural arrangement, the pipe supports serve to limit and guide the piping.
[0015] In a specific embodiment, the waste liquid tank, cleaning fluid tank, and pure water tank are each connected to their respective pipelines. This structural arrangement ensures that the connections of the waste liquid tank, cleaning fluid tank, and pure water tank to the pipelines are independent and do not interfere with each other.

Then, the cleaning fluid tank 10 and the pure water tank 13 are filled and placed in the corresponding positions on the weighing module. The corresponding tank adapter 14, quick-connect female connector 12, and quick-connect male connector 11 are then connected sequentially. Connector female 12, quick connector male 11 and pipe 8. At this time, the weighing sensor sends the data of the cleaning fluid tank weighing sensor 18 and the pure water tank weighing sensor 16 to the control unit to determine that the cleaning fluid tank 10 and the pure water tank 13 are in place. After the process starts, as the liquid in the cleaning fluid tank 10 and the pure water tank 13 decreases, the liquid volume in the waste liquid tank 6 increases.
