Description

Technical Field

[0001] This utility model relates to the field of thyroid biopsy technology, and in particular to a device for delivering thyroid fine needle biopsy slide specimens. Background Technology

[0002] Fine-needle aspiration biopsy (FNA) is widely adopted as the preferred diagnostic tool for assessing the nature of thyroid nodules. This process involves multiple medical fields, including endocrinology, thyroid and general surgery, head and neck surgery, ultrasound medicine, interventional radiology, and pathology, forming an interdisciplinary diagnostic and treatment workflow.

[0003] During fibrillation-naïve aspiration (FNA), non-pathologists typically perform the procedure in the operating room, biopsy room, or ultrasound-guided interventional room. After aspiration, the obtained sample is evenly distributed across multiple glass slides, which are then sent to the pathology department for cytological analysis. However, because FNA is essentially an outpatient procedure, patients usually need to pay the fees themselves or have a family member deliver the sample to the pathology department, which often means a walking distance between the examination location and the pathology laboratory.

[0004] Currently, the method of transporting these slides is rather primitive. They are usually laid flat on a hard surface, such as an ultrasound report, and then carried by the patient or their family. Because slides are thin and fragile, and given the high volume of people in hospitals, they are extremely prone to slipping and breaking during transport, rendering the samples unusable. Furthermore, the cell-side of the slide is exposed, and it may flip during transport, causing cell contamination or loss, affecting subsequent pathological analysis. This is especially challenging in winter when patients are wearing heavy clothing or carrying other items, increasing the risk of slides accidentally falling. Utility Model Content

[0005] The purpose of this invention is to provide a device for delivering thyroid fine needle aspiration glass slide specimens, which aims to solve the problems of easy dropping, breakage, and contamination during the delivery of thyroid fine needle aspiration glass slide specimens.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a device for delivering thyroid fine needle aspiration slide specimens, comprising: a box body and a cover attached to the box body;

[0007] The box has a receiving cavity for accommodating glass slides. A baffle is horizontally arranged inside the box, which divides the receiving cavity into an upper cavity and a lower cavity. Multiple partitions are vertically arranged in the lower cavity, and each partition is perpendicular to the baffle. The multiple partitions are arranged side by side along the length of the box to divide the lower cavity into multiple sub-cavities.

[0008] The baffle is provided with a plurality of through slots for connecting the upper cavity to each of the sub-cavities, and the plurality of glass slides enter the corresponding sub-cavities from the upper cavity through each of the through slots;

[0009] The housing is provided with a clamping part for clamping the glass slide located in the upper cavity, and the cover is provided with a corresponding clamping mating part. When the cover is fastened to the housing, the clamping mating part drives the clamping part to clamp the glass slide.

[0010] Furthermore, the cavity is provided with a carrier to support the glass slide, and the carrier is provided with a slot corresponding to the through groove.

[0011] Furthermore, the carrier and the baffle are integrally formed, or the carrier and the baffle are separately formed.

[0012] Furthermore, the clamping part is configured in multiple ways corresponding to each of the sub-cavities, and the clamping mating part is configured in a one-to-one correspondence with the clamping part.

[0013] Furthermore, the clamping part consists of two clamping blocks that are slidably disposed on the baffle and symmetrically disposed on two opposite sides of the through groove;

[0014] The clamping engagement part consists of two wedge-shaped blocks disposed on the cover body corresponding to the two clamping blocks. When the cover body is fastened onto the box body, the wedge-shaped blocks abut against the clamping blocks and can drive the two clamping blocks to move closer to each other to clamp the glass slide.

[0015] Furthermore, the baffle is also provided with a guide for guiding the clamping block to slide along the sliding direction of the clamping block. One end of the guide is fixed, and the other end of the guide is inserted into the clamping block. The clamping block is provided with an insertion hole corresponding to the guide.

[0016] Furthermore, an elastic element for guiding the clamping block to slide and reset is sleeved on the guide member. One end of the elastic element is fixed, and the other end of the elastic element is connected to the clamping block.

[0017] Furthermore, the distance D between the baffle and the cover is 1.5cm-2cm.

[0018] Furthermore, the length l of the through groove is 2-2.2cm, and the width k of the through groove is 0.15-0.25cm.

[0019] Furthermore, a locking ring for locking is provided between the cover and the box.

[0020] The beneficial effects of the thyroid fine-needle aspiration slide specimen delivery device provided by this utility model are as follows:

[0021] Compared with the prior art, the present invention provides a thyroid fine-needle aspiration slide specimen delivery device.

[0022] The internal structure of the enclosure is designed with multiple independent compartments, separated by vertical partitions. This ensures that each slide has its own independent space, preventing contact and collision between slides and reducing the risk of breakage. Simultaneously, the slides enter the compartments through slots in the baffles and are positioned in pre-designed carrier slots, ensuring stable storage of the specimens and preventing them from tipping or shifting during transport, effectively avoiding sample contamination or cell loss. The clamping mechanism in the upper compartment works in conjunction with the clamping mechanism on the cover, automatically clamping the slides when the cover is closed, ensuring the safety of the specimens during transport. Even under bumpy or tilted conditions, the slides remain stable, reducing the possibility of human error and improving the overall efficiency and quality of specimen transport.

[0023] Furthermore, the sliding design of the clamping block, combined with the reset mechanism of the elastic element, ensures smooth operation when the device is opened and closed, while also guaranteeing quick reset after each use, facilitating reuse and efficient operation. Precise control of the dimensions of the through slots and chambers ensures that the slides can be easily inserted and securely stored, while the appropriate spacing between the baffle and the cover provides sufficient buffer space to protect the slides.

[0024] Furthermore, the locking ring mechanism between the housing and the lid further enhances the device's sealing, preventing accidental opening during transport and ensuring the safety of the specimens. The carrier and baffle can be either integrally molded or separate components, simplifying the manufacturing process, providing flexibility for maintenance and replacement, and extending the device's service life.

[0032] To make the technical problems, technical solutions, and beneficial effects to be solved by this embodiment clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this embodiment and are not intended to limit this embodiment.

[0033] Please refer to the following: Figures 1 to 5 The present embodiment describes a thyroid fine-needle aspiration slide specimen delivery device. This embodiment of the thyroid fine-needle aspiration slide specimen delivery device includes a housing 1 and a cover 2 that is attached to the housing 1.

[0034] The box body 1 has a receiving cavity for accommodating glass slides. A baffle 3 is horizontally arranged inside the box body 1, which divides the receiving cavity into an upper cavity 11 and a lower cavity 12. Multiple partitions 4 are vertically arranged in the lower cavity 12, and each partition 4 is perpendicular to the baffle 3. The multiple partitions 4 are arranged side by side along the length of the box body 1 to divide the lower cavity 12 into multiple sub-cavities 121. Multiple through slots 31 are provided on the baffle 3 corresponding to each sub-cavity 121 to connect with the upper cavity 11. Multiple glass slides enter the corresponding sub-cavities 121 from the upper cavity 11 through each through slot 31.

[0035] In addition, the housing 1 is provided with a clamping part 13 for clamping the glass slide located in the upper cavity 11, and the cover 2 is provided with a corresponding clamping mating part. When the cover 2 is fastened on the housing 1, the clamping mating part drives the clamping part 13 to clamp the glass slide.

[0036] This embodiment discloses a thyroid fine-needle aspiration slide specimen delivery device. The internal structure of the housing 1 is designed with multiple independent chambers 121, divided by vertical partitions 4. This ensures that each slide has its own independent space, avoiding contact and collision between slides and reducing the risk of breakage. Simultaneously, the clamping part 13 of the upper chamber 11 is linked with the clamping engagement part on the cover 2. When the cover 2 is closed, it automatically clamps the slide, ensuring the safety of the specimen during transportation. Even under bumpy or tilted conditions, it remains stable, reducing the possibility of human error and improving the overall efficiency and quality of specimen transportation.

[0037] Based on the overall description of the above structure, the exemplary structure of a thyroid fine-needle aspiration slide specimen delivery device in this embodiment is as follows: Figure 1 and Figure 4 As shown. Firstly, the standard glass slide is 1.9cm long, 0.1cm wide, and 6cm high. To facilitate slide loading, in this embodiment, the box 1 has a cubic structure. Preferably, the length L of the box 1 is 6cm-7cm, the width K is between 2cm-2.6cm, and the height H is between 6cm-6.5cm, to accommodate the size of the glass slide. Optimally, the box 1 is 6.4cm long, 2.3cm wide, and 6.3cm high, making it easy to hold with one hand, carry, and prevent it from falling. It is understood that the box dimensions can be adjusted to suit specific needs.

[0038] Still refer to Figure 2 and Figure 3 As shown, the interior of the box 1 has a cavity for accommodating glass slides, with dimensions of 6.2 cm in length, 2.1 cm in width, and 6.1 cm in height. A baffle 3 is horizontally arranged inside the box 1, with the same length and width as the cavity. Therefore, the baffle 3 divides the cavity into an upper cavity 11 and a lower cavity 12.

[0039] Multiple partitions 4 are vertically arranged within the lower cavity 12 to divide the box 1 into multiple sub-cavities 121 along its length, thereby accommodating multiple glass slides. In a preferred embodiment, two partitions 4 are arranged within the lower cavity 12 to divide it into three sub-cavities 121, facilitating the placement of three glass slides. The reason for designing three sub-cavities 121 is that each nodule requires 2-6 glass slide specimens, mostly 3; therefore, it is reasonable to design each box to hold 3 glass slides.

[0040] Each cavity 121 has a through slot 31 at its top for inserting a glass slide. Preferably, each cavity 121 contains a carrier 6 to support the glass slide, the carrier 6 filling the cavity 121, and a slot 61 corresponding to the through slot 31 is provided on the carrier 6. When a glass slide enters the cavity 121 through the through slot 31, the glass slide can only be placed in the slot 61, reducing the movement space of the glass slide within the cavity 121, thereby improving the support stability of the glass slide and effectively preventing breakage of the glass slide.

[0041] In this embodiment, the baffle 3 and the carrier 6 can be integrally formed using the same material, and a corresponding through groove 31 is formed at the position where the glass slide needs to be inserted. In this case, the through groove 31 and the slot 61 are also of the same structure. At the same time, an elastic pad or other structure can be set in the through groove 31 for cushioning to reduce damage to the glass slide.

[0042] Alternatively, the carrier 6 and the baffle 3 can be separate components. The carrier 6 can be a block structure with a certain degree of rigidity, made of the same material as the baffle 3, with an elastic pad on the side in contact with the glass slide for cushioning. Alternatively, the carrier 6 as a whole can be a structure with certain elastic properties, such as rubber. The carrier 6 itself has both rigidity and elasticity, thus providing support and cushioning for the glass slide and preventing breakage.

[0043] It should be noted that in this embodiment, the distance D between the baffle 3 and the cover 2 is 1.5cm-2cm. For example, it can be set to any value within this range, such as 1.5cm, 17cm, or 2cm, without any specific limitation. As optimal, the distance D can be set to 1.7cm, which provides sufficient space for the operator's hands when placing the slide into the box 1, so as to insert the slide into the through slot 31 more securely.

[0044] In this embodiment, the length l of the through groove 31 is 2-2.2 cm, and the width k of the through groove 31 is 0.15-0.25 cm. Optimally, the length l of the through groove 31 is 2.1 cm, and the width k of the through groove 31 is 0.2 cm, which facilitates the insertion of the glass slide without leaving excessive space to reduce slide movement. The distance a1 between the two through grooves 31 is 1.9 cm, and the corresponding distance a2 from each through groove 31 to the housing 1 is 0.9 cm.

[0045] In addition, in this embodiment, the dimensions of the partition 4 are preferably set to a length of 2.1 cm and a width of 0.1 cm. The distance b1 between two partitions 4 is 2 cm, and the distance b2 between each partition 4 and the transverse through-slot 31 is 0.9 cm. The vertical baffle 3 can separate the slides, preventing them from sticking together and thus avoiding cell contamination or loss.

[0046] After the slides are placed inside the housing 1, during transportation, to further ensure the protection of the slides, a clamping part 13 is provided in this embodiment to clamp and protect some of the slides in the upper cavity 11. To ensure the protection of each slide, multiple clamping parts 13 are provided for each sub-cavity 121, and clamping mating parts are provided one-to-one with the clamping parts 13.

[0047] In a preferred embodiment, the clamping part 13 is slidably disposed on the baffle 3, and two clamping blocks 131 are symmetrically disposed on two opposite sides of the through groove 31. (Refer to...) Figure 4 and Figure 5 In the state shown, the clamping block 131 extends in the front-to-back direction and can be driven to slide in the left-to-right direction, thereby clamping the glass slide in the middle. The clamping mating part consists of two wedge-shaped blocks 22 provided on the cover 2 corresponding to the two clamping blocks 131. When the cover 2 is fastened on the box 1, the wedge-shaped blocks 22 abut against the clamping blocks 131 and can drive the two clamping blocks 131 to move closer to each other to clamp the glass slide.

[0048] Meanwhile, in order to improve the smoothness of the sliding of the clamping block 131, preferably, a guide 132 for guiding the sliding of the clamping block 131 is also provided in the upper cavity 11 along the sliding direction of the clamping block 131. One end of the guide 132 is fixed, and the other end of the guide 132 is inserted into the clamping block 131. The clamping block 131 is provided with an insertion hole corresponding to the guide 132.

[0049] Specifically, the guide 132 is a guide post, which is fixed in position relative to the baffle 3, and one end of the guide post is inserted into the clamping block 131 through the insertion hole. When the clamping block 131 is driven to slide by the wedge block 22, the clamping block 131 can slide smoothly under the guidance of the guide post.

[0050] Alternatively, the guide post can be fixed to the inner wall of the housing 1, or one end of the guide post can be fixed to the partition 4. Specifically, it can be implemented according to... Figure 2 and Figure 3 As shown, the top of the partition 4 passes through the baffle 3 and extends upward into the upper cavity 11, so that the bottom of the upper cavity 11 is divided into three parts corresponding to the three sub-cavities 121, and each part is provided with a clamping part 13 for clamping the glass slide.

[0051] In the upper cavity 11, the two guides 132 on the left side are used to guide the movement of the clamping block 131. During assembly, the left end of the left guide post is fixed to the inner wall of the housing 1, and the right end is slidably connected to the left clamping block 131. The right end of the right guide post is fixed to the left partition 4, and the left end is slidably connected to the right clamping block 131. The two guide posts in the middle section that are used to slide into the two clamping blocks 131 are slidably connected to the clamping block 131 at one end and fixedly connected to the partition 4 at the other end. The arrangement of the two guide posts on the right side is similar to that on the left side. The right end of the right guide post is fixed to the inner wall of the housing 1, and the left end is slidably connected to the right clamping block 131. The left end of the left guide post is fixed to the right partition 4, and the right end is slidably connected to the left clamping block 131.

[0052] Furthermore, in this embodiment, an elastic element 133 for guiding the sliding reset of the clamping block 131 is sleeved on the guide member 132. One end of the elastic element 133 is fixed, and the other end of the elastic element 133 is connected to the clamping block 131. Preferably, the elastic element 133 is a tension spring, which is sleeved on the guide post. One end of the tension spring is fixed on the guide post, and the other end of the tension spring is connected to the clamping block 131. When the clamping block 131 is driven by the wedge block 22 to slide along the guide post toward the through groove 31, the clamping block 131 returns to its original position under the tension of the tension spring when the external force is removed, making it easy to remove the glass slide.

[0053] In this embodiment, a locking ring 5 for locking is provided between the cover 2 and the box 1. (Refer to...) Figure 4 As shown, both the cover 2 and the box 1 are provided with through holes 21 that connect to the locking ring 5. After the cover 2 is placed on the box 1, the locking ring 5 is passed through the through hole 21 to lock the cover 2 onto the box 1, thereby facilitating transportation. The structure of the locking ring 5 can refer to the locking ring 5 structure in the prior art, and will not be described in detail here.

[0054] This embodiment describes a thyroid fine-needle aspiration slide specimen delivery device. In use, the cover 2 is opened, and the slide is sequentially passed through the through-slot 31 and placed into the slot 61. Next, the cover 2 is placed over the housing 1. During this process, the wedge-shaped block 22 on the cover 2 pushes the clamping block 131, which slides relative to the guide post, thereby clamping and fixing the corresponding slide using the two clamping blocks 131. Finally, the locking ring 5 is inserted into the through-hole 21 to complete the fixation of the cover 2 and the housing 1. The person delivering the specimen can directly hold the specimen delivery device without needing to maintain balance; a normal vertical grip is sufficient. The specimen is then delivered to the pathology department for testing.

[0055] This invention provides a thyroid fine-needle aspiration slide specimen delivery device that effectively prevents specimens from falling, breaking, or being contaminated during delivery, greatly improving the safety, stability, and convenience of slide specimen transport. The device is simple, inexpensive, disposable, requires no patient return, is easy to use, does not significantly increase patient puncture costs, and is easy to promote.

[0056] The above description is only a preferred embodiment of this embodiment and is not intended to limit this embodiment. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this embodiment should be included within the protection scope of this embodiment.
