DETAILED DESCRIPTION

[0032] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0033] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0034] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0036] At present, the lower end of the preparation chamber is provided with an ear handle, and the preparation chamber is installed by rotating the ear handle and snapping it into the preparation board with the slide. The installation is inconvenient, and the strength of each person to install the preparation chamber is different, so it is easy to install it improperly, resulting in different degrees of compression between the preparation chamber and the slide, which may cause leakage.

[0037] In view of the above problems, the present embodiment provides a film making chamber and a film making chamber fixing device. When installing the film making chamber, the film making chamber can be slidably clamped in the film making chamber fixing device by pressing the film making chamber, and the film making chamber is pressed tightly on the slide glass. The installation is simple and convenient, and no matter different people or a mechanical arm are used to press, the film making chamber is clamped in the same position of the film making chamber fixing device, ensuring that it is installed in place and has good sealing to avoid leakage.

[0038] Specifically, refer to Figure 1 and Figure 2, the film-making chamber F10 includes a chamber body F11 and an elastic sealing ring F12, and the chamber body F11 is cylindrical and has openings at both ends. One end where the cell fluid is dripped into is the top of the chamber body F11, and the elastic sealing ring F12 is fixed to the bottom of the chamber body F11. The free end of the elastic sealing ring F12 extends beyond the bottom of the chamber body. Under the action of pressure, the elastic sealing ring F12 can be deformed along the axial direction of the chamber body F11, and the elastic sealing ring F12 shrinks, so that the elastic sealing ring F12 is close to the slide, preventing the cell fluid dripped into the film-making chamber F10 from leaking to the outside of the film-making chamber F10. Among them, the method of fixing the elastic sealing ring F12 to the bottom of the chamber body F11 is not limited, such as the elastic sealing ring F12 is fixed to the bottom of the chamber body F11 in a close-fitting manner. The bin body F11 and the elastic sealing ring F12 of this embodiment are both plastic parts. Therefore, when manufacturing the film making bin F10, the bin body F11 and the elastic sealing ring F12 can be made in one piece, or they can be made in combination by opening a glue injection port at one end of the bin body F11 close to the slide.

[0039] The top of the bin body F11 extends outward to form an annular flange F13, the diameter of which is larger than the diameter of the bin body F11. The annular flange F13 makes it more convenient to press the film bin F10 and makes it easier and more stable to clamp the film bin F10. The height of the bin body F11 is greater than the diameter of the annular flange F13, so that the center of gravity of the entire film-making bin is located in the lower half of the entire film-making bin. In this embodiment, in order to reduce the weight of the top of the film-making bin F10 and achieve the effect of light on the top and heavy on the bottom, the center of gravity of the film-making bin is further located in the lower half of the film-making bin. An annular groove is dug at the top of the annular flange F13, and a plurality of reinforcing ribs F14 are arranged between the side wall and the bottom wall of the annular flange F13 forming the annular groove and along the circumference of the annular flange F13. One end of the reinforcing rib F14 is connected to the side wall of the annular flange F13, and the other end is connected to the bottom wall of the annular flange F13 to enhance the strength of the annular flange F13. The center of gravity of the film-making bin is located in the lower half of the film-making bin, which is conducive to the sorting and arranging of the film-making bin during the feeding stage.

[0040] A card slot F15 that is recessed into the interior of the bin body F11 is provided on the outer wall of the bin body F11, and the shape of the card slot F15 can be designed accordingly according to the shape of the elastic card head in the film-making bin fixture. The card slot F15 cooperates with the elastic card head in the film-making bin fixture to achieve the card connection between the film-making bin and the film-making bin fixture. In order to achieve the sliding card connection operation by pressing the film-making bin, a sliding surface F16 is provided between the bottom of the card slot F15 (the deepest point where the card slot is recessed inward) and the top of the card slot F15 (the connection point between the card slot and the outer wall of the film-making bin). When the film-making bin F10 is pressed into the film-making bin fixture, the elastic card head in the film-making bin fixture can move along the sliding surface F16 and be carded to the bottom of the card slot F15 to ensure that it is installed in place. The side wall of the bin body F11 where the slot F15 is located extends inwardly, and a chamfer is provided at the connection between the inner surface of the side wall of the bin body F11 and the outer surface of the elastic sealing ring F12, so that the elastic sealing ring F12 is more firmly embedded in the inner wall of the bin body F11.

[0041] A plurality of slots F15 may be provided along the outer wall of the bin body F11. Preferably, the slots F15 are annular grooves on the outer wall of the bin body F11, so there is no need to consider the horizontal deflection angle when installing the film making bin F10.

[0042] In this embodiment, the cross section of the sliding surface F16 is an arc shape, which can match the spherical elastic clamp in the film making chamber fixing device, and can make the film making chamber and the film making chamber fixing device more smoothly clamped when pressed. However, the cross-sectional shape of the sliding surface F16 is not limited to this, and can also be: the shape of the bottom of the card slot F15 matches the shape of the elastic clamp of the film making chamber fixing device, and then connected to the top of the card slot F15 through a straight line at a certain angle, which can also achieve the effect of sliding clamping when pressed.

[0043] After the film-making bin adopts the above structure, it can be pressed and fixed. Compared with the existing film-making bin, the installation is simpler and more convenient. Even if different forces are used when installing the film-making bin, the film-making bin can finally return to the same snap-on position to ensure that it is installed in place.

[0044] In order to realize the sliding engagement of the film making chamber, this embodiment further provides a film making chamber fixing device F20, referring to Figure 3 , Figure 4 and Figure 5 , including a body F21 and an elastic clamp. The body F21 is provided with a through hole F23 for the film making chamber F10 to be pressed into, and the position of the elastic clamp is not fixed, and can move linearly with external force, and can be clamped in the clamping groove of the film making chamber F10 under the action of pressing force, so as to realize the clamping connection between the film making chamber fixing device F20 and the film making chamber F10.

[0045] Since the slot F15 in the film making chamber F10 of this embodiment is semicircular, a positioning glass bead F22 with a spring (i.e., a spring is fixed on the positioning glass bead F22) is used as an elastic clamp. The positioning glass bead F22 is spherical and is pushed by elastic force to match the shape of the slot F15. However, the elastic clamp is not limited to this structure, and a conventional latch head can also be used as the elastic clamp; other elastic parts can also be used to push the positioning glass bead F22, such as a bolt with a spring.

[0046] The main body F21 is provided with a plurality of channels F24 connected to the through hole F23, and the channels F24 are arranged along the circumference of the through hole F23. The positioning glass beads F22 and the elastic member are installed in the channels F24, and under the thrust of the elastic member, the positioning glass beads F22 are partially exposed in the through hole F23. When pressed into the film-making chamber F10, the positioning glass beads F22 are squeezed by the outer wall of the film-making chamber F10 and retract into the channels F24. After that, when the card slot F15 of the film-making chamber F10 reaches the position of the positioning glass beads F22, the positioning glass beads F22 slide into the bottom of the card slot F15 of the film-making chamber F10. The positioning glass beads F22 are connected to the film-making chamber F10.

[0047] The positioning bead F22 of this embodiment has a spring. To facilitate the installation of the positioning bead F22, one end of the channel F24 is connected to the through hole F23, and the other end passes through the body F21 to the outside of the body F21. The positioning bead F22 can be installed by placing the positioning bead F22 inwardly at the channel opening facing the outside of the body F21.

[0048] In order to facilitate the placement of the glass slide F30, a clearance gap F25 for placing the glass slide F30 is also provided on the main body F21 below the through hole F23. The height of the clearance gap F25 is higher than the thickness of the glass slide. Specifically, in this embodiment, downwardly extending bosses F26 are provided on opposite sides of the main body F21. The shape of the bosses F26 is not limited, and the gap between the two bosses F26 forms the clearance gap F25. When the glass slide F30 is extended into the clearance gap F25 and the film-making chamber F10 is pressed into the film-making chamber fixing device F20, the elastic sealing ring F12 on the film-making chamber F10 can be close to the glass slide F30 to prevent the cell fluid dripped into the film-making chamber F10 from leaking out.

[0049] A mounting hole F28 for fixing the film-making chamber fixing device F20 is also provided on the boss F26, and the film-making chamber fixing device F20 can be threadedly fixed on the film-making frame through the mounting hole F28.

[0050] In this embodiment, the body is similar to an "X" shape, and an avoidance area F27 is set in the center of the body F21, so that it is more convenient to take and put the preparation chamber F10 and the slide glass F30, and it is not easy to collide with the body F21, and it can also reduce the overlap area of ​​the preparation chamber fixing device F20 and the slide glass F30, so as to prevent the body F21 from scraping the cell sample on the slide glass F30 when taking out the slide glass F30. A clamping groove F29 is also set to facilitate the pressing in and out of the preparation chamber.

[0051] When preparing and staining the slide, first insert the slide F30 vertically into the clearance gap F25 along the direction of the avoidance area F27, and then press the slide chamber F10 into the slide chamber fixing device F20, so that the slide chamber F10 is slidably engaged in the slide chamber fixing device F20. At this time, the slide chamber is tightly pressed on the slide. Figure 6 and Figure 7 As shown, the liquid-based cell preparation and staining operation can then be performed. After the preparation and staining is completed, first take out the preparation chamber, then take out the slide, and proceed to the next step of sealing operation.

[0052] In summary, when the film making chamber is connected to the film making chamber fixing device by pressing, the pressing force can be different, and finally the film making chamber can be returned to the same position of the film making chamber fixing device through the sliding surface. The installation is simple and convenient, ensuring that it is installed in place and avoiding leakage.

[0053] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
