Description

Technical Field

[0001] This invention belongs to the field of testing and inspection technology, specifically relating to a cell smear carrier device. Background Technology

[0002] Cell smears are a technique used for microscopic observation of cell samples obtained by uniformly spreading a cell sample onto a glass slide, followed by fixation, staining, and other treatments. They are widely used in pathological diagnosis, microbial detection, and scientific research analysis. The core steps include sampling, smearing, fixation, staining, and microscopic examination. Appropriate methods must be selected based on the sample type to ensure accurate results.

[0003] In current testing and inspection procedures, cell smears are typically prepared by placing the slide directly on a clean work surface. However, since the work surface is usually flat and the slide is thin, tweezers or similar tools are generally used to pick up the slide after smearing. But because the slide is thin and adheres to the work surface, and due to the thickness of the tweezers, it often requires multiple attempts to pick up the slide, and these multiple attempts may damage the slide. Utility Model Content

[0004] The purpose of this invention is to provide a cell smear support device that provides a platform for placing glass slides, facilitating the placement and smearing of slides, and making it easier for staff to pick up the slides after smearing.

[0005] The specific technical solution adopted in this utility model is as follows: A cell smear support device includes a base with a hollow interior. A fixed clamp and a movable clamp are respectively provided at the left and right ends of the base. The fixed clamp is fixedly mounted on the base, and the movable clamp is fixedly mounted on the outer end of a connecting rod. The connecting rod is slidably connected inside the base, and a spring is sleeved on the connecting rod. One end of the spring abuts against the inner side of the base, and the other end of the spring abuts against the inner end of the connecting rod. Support assemblies are respectively provided on the front and rear sides of the base.

[0006] In a preferred embodiment, a base plate is provided at the lower end of the base, and a base pad is fitted onto the lower end surface of the base plate.

[0007] In a preferred embodiment, both the clamping surfaces of the fixed clamping plate and the movable clamping plate are provided with anti-slip ripples, and a handle ring is installed on the outer side of the movable clamping plate.

[0008] In a preferred embodiment, the support assembly includes a retainer fixed to the outer side of the base, the inner side of the retainer being provided with a slot for engaging the retaining strip, a cantilever plate being installed on the outer side of the retaining strip, a support rod being threadedly connected to the cantilever plate, and a self-crushing cup being installed at the lower end of the support rod.

[0009] In a preferred embodiment, a force-adding rod is mounted at the top of the support rod.

[0010] In a preferred embodiment, the card slots in the card holders on the front and back sides are arranged in opposite directions.

[0011] The technical effects achieved by this utility model are as follows: When performing cell smears, this device first places the slide on the smearing apparatus and clamps it in place using a fixed clamp and a movable clamp. Then, the cell smearing operation is performed. After the cell images are taken, the movable clamp is moved away from the fixed clamp to release the slide, allowing it to be easily lifted and placed on a microscope for observation and testing. This smearing apparatus makes it easier for laboratory personnel to lift and operate the slide during smearing. In this application, when clamping glass slides, to prevent displacement between the device and the operating table, which would make it difficult to clamp the glass slides, the device can be fixed and positioned between the device and the operating table by using the self-suction cup of the support component to adhere to it, thereby improving the stability of the device placement.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0018] Please see the appendix Figures 1 to 4 As shown, this utility model provides a cell smear support device, including a base 1. The base 1 has a hollow interior. Fixed clamping plates 2 and movable clamping plates 4 are respectively provided at the left and right ends of the base 1. Fixed clamping plates 2 are fixedly installed on the base 1, and movable clamping plates 4 are fixedly installed on the outer end of a connecting rod 3. The connecting rod 3 is slidably connected inside the base 1. A spring 31 is sleeved on the connecting rod 3. One end of the spring 31 abuts against the inner side of the base 1, and the other end of the spring 31 abuts against the inner end of the connecting rod 3. Support components 5 are respectively provided on the front and rear sides of the base 1. In this application, to facilitate the handling of glass slides during cell smear preparation, the device is first placed on the operating table. Then, the movable clamp 4 is pulled away from the fixed clamp 2. The glass slide is then placed between the fixed clamp 2 and the movable clamp 4, and the movable clamp 4 is released. The spring force of the spring 31 causes the movable clamp 4 to move closer to the fixed clamp 2 to hold the glass slide. The smear preparation is then performed on the glass slide. After the smear is completed, the movable clamp 4 can be pulled away from the fixed clamp 2 again to remove the glass slide. Furthermore, to prevent the device from moving between the device and the operating table during smear preparation, which could cause the smear to be unstable, the self-suction cup 56 on the support assembly 5 can be attached to the operating table to fix the device to the operating table. The back-and-forth movement of the movable clamping plate 4 causes the connecting rod 3 to extend and retract within the base 1. Due to the connecting effect of the connecting rod 3, the movement of the movable clamping plate 4 becomes more stable.

[0019] Both the clamping surfaces of the fixed clamping plate 2 and the movable clamping plate 4 are provided with anti-slip ripples, and a handle ring 41 is installed on the outer side of the movable clamping plate 4. To improve the stability of the glass slide clamping, anti-slip corrugations are made on the clamping surfaces of both the fixed clamp 2 and the movable clamp 4, increasing the stability of the contact between the clamps and the glass slide. Furthermore, to facilitate pulling the movable clamp 4, a handle ring 41 is installed on the outer side of the movable clamp 4. When pulling the movable clamp 4, a finger can be inserted into the handle ring 41 to pull it.

[0020] A base plate 11 is provided at the lower end of the base 1, and a base pad 12 is attached to the lower end surface of the base plate 11. A base pad 12 is installed under the base plate 11. The base pad 12 can be made of rubber to increase the friction with the operating table.

[0021] The support assembly 5 includes a card holder 51 fixed to the outer side of the base 1. The inner side of the card holder 51 is provided with a slot 52 for engaging the card strip 53. A cantilever plate 54 is installed on the outer side of the card strip 53. A support rod 55 is threadedly connected to the cantilever plate 54. A self-suction cup 56 is installed at the lower end of the support rod 55, and a force-adding rod 57 is installed at the top end of the support rod 55. When clamping the glass slide, in order to avoid displacement between the device and the operating table, which would make it inconvenient to clamp the glass slide, the self-suction cup 56 of the support component 5 can be used to attach the device to the operating table to fix the device and the operating table, thereby improving the stability of the device placement. Regarding the specific operation of the support component 5, after the device is placed on the operating table, by rotating the force-adding rod 57, the support rod 55 and the cantilever plate 54 are rotated relative to each other, causing the support rod 55 to move the self-suction cup 56 downward, so that the self-suction cup 56 is attached to the operating table to form a fixed connection, making the connection between the device and the operating table more stable. Furthermore, when the self-suction cup 56 is attached to the operating table, the bottom pad 12 on the base plate 11 is still in contact with the table.

[0022] The card slots 52 inside the card holders 51 on the front and back sides have opposite opening directions; The cantilever plate 54, support rod 55, self-suction cup 56, and force-applying rod 57 in the support assembly 5 are secured in the slots 52 of the mounting base 51 by a locking strip 53, thus connecting with the base 1. To ensure the locking strip 53 can be easily engaged in the slots 52 and to facilitate disassembly, an opening is provided at one end of the slots 52. To prevent the locking strip 53 from sliding along the slots 52 or even slipping off when the base 1 is subjected to a unidirectional thrust in the left-right direction, the openings of the two slots 52 in this device are opposite in direction. Figure 3 and Figure 4 As shown, in Figure 3 In the left-right direction shown, one slot 52 opening is opened at the left end and the other slot 52 opening is opened at the right end. This can prevent the base 1 from being pushed and causing the slot 52 and the strip 53 to slip off when the two openings are opened in the same direction.

[0023] The working principle of this utility is as follows: When performing cell smears, in order to facilitate the placement and removal of the slide, first place the device on the operating table, then pull the movable clamp 4 away from the fixed clamp 2, place the slide between the fixed clamp 2 and the movable clamp 4, and release the movable clamp 4. The elastic force of the spring 31 will drive the movable clamp 4 to move closer to the fixed clamp 2 to clamp the slide, and then perform the smear operation on the slide. After the smear is completed, the movable clamp 4 can be pulled away from the fixed clamp 2 again to remove the slide. Furthermore, to prevent the device from moving between the device and the operating table during the coating process, which could result in unstable coating, the self-suction cup 56 on the support assembly 5 can be attached to the operating table to fix the device to the operating table.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
