Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a mobile sample tray used in a cryostat. Background Technology

[0002] As a core piece of equipment in pathological diagnosis, the frozen section machine has a built-in tray for fixing and freezing patient tissue samples. In current technology, pathologists freeze and fix samples marked with pathology numbers onto the tray for sectioning, and then temporarily store the frozen tray inside the machine after diagnosis. Due to the surge in clinical sample volume, multiple pathology numbers are often present for the same patient, but the limited storage space inside the machine necessitates frequent tray transfers and removals of multiple batches of samples. Furthermore, the frozen trays for different patients lack a visual labeling system within the machine, relying solely on manual memory or external records for differentiation.

[0003] However, existing frozen section analyzers have the following drawbacks in their sample storage areas: the lack of a labeling device linked to pathology numbers, which can easily lead to sample cross-contamination during tray removal. This sample confusion caused by limited space and missing labels not only affects diagnostic efficiency but also poses a risk of clinical misdiagnosis, necessitating improvements to the storage architecture to enhance sample management security. Summary of the Invention

[0004] This invention proposes a mobile sample tray for use in cryostats, which solves the problem of the lack of identification linked to pathology numbers in the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A mobile sample tray for use in a cryostat includes a tray body divided into two sides, which are a placement area and a labeling area, respectively. The placement area is configured to detachably fix multiple cryostat heads. The labeling area is configured to adjustably display pathology number identifiers and includes a fixing structure for supporting the identifier components and a protective structure for covering the identifier components. An operation window for exposing part of the identifier components is formed between the protective structure and the labeling area.

[0007] Furthermore, the placement area includes at least two placement slots, which are circular; the bottom of the freezing support head is provided with a stepped flange, and the outer peripheral surface of the stepped flange is fitted with the inner wall of the placement slot to achieve detachable fixation.

[0008] Furthermore, the labeling component of the label area includes at least one digital roller, which is rotatably mounted on the base of the label area via a fixed shaft.

[0009] Furthermore, the protective structure is a fixed cover, and a barrier with positioning holes is provided on the back of the substrate of the label area. The back of the fixed cover is adapted to the barrier and is provided with a positioning block that engages with the positioning holes.

[0010] A cavity for accommodating the digital roller is formed between the fixed cover and the label area, and an operation window is provided above the cavity.

[0011] Furthermore, the receiving cavity is formed by the matching of the receiving groove A inside the fixed cover and the receiving groove B of the label area substrate.

[0012] The beneficial effects of the technical solution provided in this application are as follows:

[0013] 1. This movable sample tray, used in cryostats, features an adjustable pathology number labeling area, allowing healthcare professionals to quickly and accurately adjust patient information and effectively avoid confusion between multiple samples. The combination of a protective structure and an operating window prevents contamination or accidental activation of the labeling components in low-temperature environments while ensuring clear visibility of critical information, enhancing operational convenience. The stability of the fixed structure guarantees reliable operation of the labeling components, further reducing medical risks caused by labeling errors.

[0014] 2. This mobile sample tray, used in cryostats, features a detachable, multi-slot design for the placement area, supporting the simultaneous attachment of multiple cryostat heads and significantly improving sample processing efficiency. The standardized slot dimensions and spacing ensure neat sample storage while minimizing space usage, adapting to the limited internal space of cryostats. The detachable structure facilitates quick replacement and cleaning of the tray heads, reducing the risk of cross-contamination and simplifying the tray removal process, thus contributing to the accuracy and timeliness of pathological diagnosis.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1-5 A mobile sample tray for a cryostat is disclosed, comprising a tray body 10, which is divided into two sides: a placement area 11 and a labeling area 12. This functional zoning allows sample storage and labeling management to operate independently, avoiding spatial interference. The placement area 11 is configured to detachably fix multiple cryostat heads 23, supporting rapid installation and removal of batch samples, adapting to machine space limitations, and facilitating cleaning and maintenance. The labeling area 12 is configured to adjustably display pathology number identifiers, including a fixing structure for supporting the identifier components and a protective structure covering the identifier components. The protective structure and the labeling area 12 form an operating window exposing part of the identifier components.

[0024] In some embodiments, the placement area 11 includes at least two circular placement slots 13. The bottom of the freezing tray 23 is provided with a stepped flange 24, and the outer peripheral surface of the stepped flange 24 is fitted with the inner wall of the placement slot 13 to achieve detachable fixation. The placement slot 13 adapts to the bottom size of the freezing tray 23 through a standardized aperture, ensuring that the tray 23 is firmly fixed after being inserted, avoiding displacement or detachment caused by low-temperature shrinkage. Multiple placement slots 13 are arranged at intervals along the length of the tray body 10, enabling parallel storage of multiple samples, improving space utilization, and reducing mutual interference during tray removal operations. The geometry of the circular placement slot 13 reduces edge stress concentration through uniform force distribution, preventing the tray 23 from detaching due to deformation or vibration in low-temperature environments. The bottom of the freezing tray 23 is provided with a stepped flange 24, and the outer peripheral surface of the stepped flange 24 is fitted with the inner wall of the placement slot 13 to achieve detachable fixation. By designing the stepped flange 25 at the bottom of the frozen support head 23 to have an outer diameter slightly smaller than the inlet diameter of the placement groove 13, it is ensured that the support head 23 can be inserted vertically. A small gap is maintained between the inner wall of the placement groove 13 and the outer peripheral surface of the stepped flange 25 to avoid jamming caused by low-temperature deformation. When the frozen support head 23 is inserted, its stepped flange 25 is placed vertically into the placement groove 13 by gravity and size adaptation. When disassembling, the flange 25 can be quickly removed by vertically lifting the support head 23 to detach it from the bottom edge of the placement groove 13.

[0025] In some embodiments, the labeling component of the label area 12 includes at least one digital roller 15, which is rotatably mounted on the base of the label area 12 via a fixed shaft 14. The outer circumferential surface of the digital roller 15 is provided with numerical markings from 0 to 9, allowing medical staff to manually adjust the pathology number by moving the roller 15, achieving intuitive matching of the markings. The two ends of the fixed shaft 14 are limited by the barriers 21 on both sides of the base, constraining the roller 15 to rotate only around the shaft, avoiding misalignment of the markings caused by axial displacement.

[0026] In some embodiments, the protective structure is a fixed cover 17. A barrier 21 with positioning holes is provided on the back of the substrate of the label area 12. The back of the fixed cover 17 is adapted to the barrier 21 and is provided with a positioning block 22 that engages with the positioning holes. The engagement between the positioning block 22 and the barrier 21 is achieved through a mechanical interlocking mechanism, ensuring that the fixed cover 17 is accurately installed and tightly covers the label area 12, preventing the cover from loosening or the seal from failing in low-temperature environments. A receiving cavity 19 is formed between the fixed cover 17 and the label area 12 to accommodate the digital roller 15. An operation window 20 is provided above the receiving cavity 19. The fixed shaft 14 and the barrier 21 form a rigid support frame, restricting the axial freedom of the digital roller 15 and ensuring that it can only rotate precisely around the shaft. The receiving cavity 19 restricts the vertical displacement space of the digital roller 15, constraining it to rotate only around the fixed shaft 14 within a preset range. The exposed digital label on the roller 15 is visible through the operation window, facilitating manual adjustment of the pathology number. The limiting design of the fixed shaft 14 prevents roller displacement caused by low-temperature shrinkage or vibration. This mechanical linkage structure, through constrained rotational freedom and intuitive operation design, achieves stable display and rapid adjustment of the pathology number label in low-temperature environments, avoiding the risk of confusion between multiple samples.

[0027] In some embodiments, the receiving cavity 19 is formed by the mating of a receiving groove A16 opened within the fixed cover 17 and a receiving groove B18 of the label area 12 base. The receiving grooves A16 and B18 form a stepped limiting structure through a depth difference. The deeper portion 16 of receiving groove A restricts the downward movement of the roller 15, while the shallower portion 18 of receiving groove B constrains the upward movement of the roller 15. Together, they control the axial displacement range of the roller 15. Simultaneously, the inner wall of the mated receiving cavity 19 is clearance-fitted with the outer circumferential surface of the roller 15, allowing it to rotate freely but preventing radial wobble. This split-type groove design, through mechanical constraints and dimensional adaptation, ensures the precise positioning and reliable operation of the roller 15.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
