Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell detection technology, specifically to an auxiliary device for pathological cell detection. Background Technology
[0002] The commonly used method for pathological cell detection is the sedimentation slide preparation method of liquid-based cytology. This method first removes impurities that affect diagnosis by centrifugation and separates cells with diagnostic value. Then, based on the different specific gravities of different types of human cells (pathological cells have a higher specific gravity and settle faster), they are allowed to settle naturally in an independent slide preparation chamber. The cells with a higher specific gravity will first adhere to the surface of the specially treated glass slide, thereby capturing pathological cells and cells with diagnostic value to the greatest extent.
[0003] The implementation of this technical solution has at least the following drawbacks: During pathological cell detection, pathological cells are typically separated from other cells based on their high density and rapid sedimentation. However, after separation, the pathological cells that have settled at the bottom are often difficult to remove, thus increasing the separation time and requiring improvement. Therefore, we propose an auxiliary device for pathological cell detection. Utility Model Content
[0004] The purpose of this invention is to provide an auxiliary device for pathological cell detection, which solves the problem mentioned in the background art that after separation, the pathological cells that usually settle at the bottom are inconvenient to remove, thus increasing the separation time of the pathological cells.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a pathological cell detection auxiliary device, comprising a first tube body, a second tube body being provided at the lower end of the first tube body, an annular rubber frame being bonded to the lower end of the first tube body, positioning rods being provided on both sides of the annular rubber frame, positioning grooves being provided on both sides of the second tube body, and a sliding rod being fixedly installed at the upper end of the positioning rods;
[0006] The first tube body has grooves on both sides, and an electromagnet is fixedly installed at the upper end of the inner cavity of the groove. The annular rubber frame has accommodating cavities on both sides, and a cover plate is provided inside the accommodating cavity. A traction rope is fixedly connected to one side of the cover plate, and the other end of the traction rope passes around the guide wheel and is fixedly connected to the upper end of the positioning rod.
[0007] By adopting the above technical solution, the two positioning rods can be pulled outward along the direction of the chute, thereby separating the positioning rods from the positioning groove. This facilitates the separation of the first tube and the second tube, making it easier for staff to remove the pathological cells that have settled into the second tube, thus shortening the separation time for the pathological cells. Furthermore, during the pulling of the positioning rods, the traction rope connected to the positioning rods loses its traction force. Then, due to the spring's elasticity, the return spring moves the sealing plate towards the center, causing the two sealing plates to press together. This blocks other cells that have not settled in the first tube, preventing other cells from spilling out.
[0008] Optionally, the size of the slide rod is adapted to the size of the slide groove, and the slide rod and the slide groove are slidably connected.
[0009] By adopting the above technical solution, the stability of the positioning rod's movement can be guaranteed through the cooperation of the sliding rod and the sliding groove.
[0010] Optionally, a return spring is fixedly installed on one side of the cover plate, and the other end of the return spring is fixedly connected to the inner wall of the receiving cavity.
[0011] By adopting the above technical solution and setting a reset spring, the cover plate can be reset.
[0012] Optionally, the size of the annular rubber frame is larger than the size of the upper port edge of the second tube.
[0013] By adopting the above technical solution, it is easy to ensure the sealing effect of the annular rubber frame between the first tube and the second tube.
[0014] Optionally, the size of the positioning rod is adapted to the size of the positioning groove, and the positioning rod is movably connected to the positioning groove.
[0015] By adopting the above technical solution, the first tube and the second tube can be connected and positioned by the cooperation of the positioning rod and the positioning groove.
[0016] Optionally, the upper end of the slide bar is in contact with the lower end of the electromagnet.
[0017] By adopting the above technical solution and setting up an electromagnet, the sliding rod can be attracted and limited.
[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0019] The technical solution of this application, through the setting of a first tube, a second tube, positioning rods, an electromagnet, a traction rope, a sealing plate, and a return spring, can both pull the two positioning rods outward along the direction of the slide groove, thereby separating the positioning rods from the positioning groove, thus facilitating the separation of the first tube and the second tube, and making it easier for staff to remove the pathological cells that have settled into the second tube, thereby shortening the separation time of the pathological cells. In addition, during the pulling of the positioning rods, the traction rope connected to the positioning rods loses its traction force, and then, due to the spring's elasticity, the return spring drives the sealing plate to move towards the center, thereby bringing the two sealing plates together, thus blocking other cells that have not settled in the first tube and preventing other cells from spilling out.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a pathological cell detection auxiliary device, including a first tube 1, a second tube 11 at the lower end of the first tube 1, an annular rubber frame 12 bonded to the lower end of the first tube 1, positioning rods 2 on both sides of the annular rubber frame 12, positioning grooves 21 on both sides of the second tube 11, and a sliding rod 22 fixedly installed at the upper end of the positioning rods 2.
[0026] The first tube 1 has sliding grooves 23 on both sides. An electromagnet 24 is fixedly installed at the upper end of the inner cavity of the sliding groove 23. The annular rubber frame 12 has receiving cavities 4 on both sides. A cover plate 5 is installed inside the receiving cavity 4. A traction rope 3 is fixedly connected to one side of the cover plate 5. The other end of the traction rope 3 passes around the guide wheel and is fixedly connected to the upper end of the positioning rod 2. The size of the annular rubber frame 12 is larger than the size of the upper end edge of the second tube 11, so as to ensure the sealing effect of the annular rubber frame 12 between the first tube 1 and the second tube 11. The size of the positioning rod 2 is adapted to the size of the positioning groove 21, and the positioning rod 2 is movably connected to the positioning groove 21. Through the cooperation of the positioning rod 2 and the positioning groove 21, the first tube 1 and the second tube 11 can be connected and positioned. The upper end of the sliding rod 22 is in contact with the lower end of the electromagnet 24. Through the setting of the electromagnet 24, the sliding rod 22 can be attracted and limited.
[0027] The dimensions of the slide rod 22 are matched with the dimensions of the slide groove 23, and the slide rod 22 and the slide groove 23 are slidably connected. The stability of the movement of the positioning rod 2 can be ensured by the cooperation between the slide rod 22 and the slide groove 23.
[0028] A reset spring 6 is fixedly installed on one side of the cover plate 5, and the other end of the reset spring 6 is fixedly connected to the inner wall of the receiving cavity 4. The reset spring 6 can drive the cover plate 5 to reset.
[0029] During separation, pathological cells and other cells are first separated through the first tube 1 and the second tube 11. Due to the high density of pathological cells, they settle quickly and will settle into the second tube 11 first. Then, the electromagnet 24 is turned off, and the two positioning rods 2 are pulled outward along the slide 23, thereby separating the positioning rods 2 from the positioning groove 21. This facilitates the separation of the first tube 1 and the second tube 11, making it easier for staff to remove the pathological cells that have settled into the second tube 11, thus shortening the separation time for pathological cells. At the same time, during the pulling of the positioning rods 2, the traction rope 3 connected to the positioning rods 2 loses its traction force. Then, due to the spring's elasticity, the reset spring 6 moves the sealing plate 5 towards the center, causing the two sealing plates 5 to press together, thereby blocking other cells that have not settled in the first tube 1 and preventing other cells from spilling out.
