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] When making thin-layer cell smears in batches, many preparation chambers, slides and related fixing devices are arranged on the workbench, which takes up a large space and is inconvenient to operate; when using a fully automatic liquid-based cell slide making machine for automatic preparation, not only the stroke of the robot arm is increased, but also the size of the fully automatic liquid-based cell slide making machine becomes larger.

[0037] In view of the problems that currently thin-layer cell smears are large in space and inconvenient to operate when they are made in batches, the utility model provides a preparation frame, including a base, the base is provided with a supporting bottom, the base is trapezoidal, each step is a fixed platform for fixing the preparation chamber, that is, at least two fixed platforms are included, and the distances between the fixed platforms and the supporting bottom are different. When thin-layer cell smears are made in batches, space is saved, the maximum utilization effect can be achieved within a limited space, and the use is more convenient.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, at least one base G11 is arranged in the film rack G10, and six bases G11 are arranged side by side in this embodiment. It should be noted that the arrangement of the multiple bases G11 is not limited to side by side, and can also be arranged in a fan shape, or arranged along a circular radial direction.

[0039] The shape of the base G11 is not limited, and can be a terrace or a pyramid. A plurality of fixed platforms G12 are arranged on the base G11. A glass slide clamping device G13 is arranged on each fixed platform G12, so that the slide glass G30 can be inserted and installed on the fixed platform G12.

[0040] A fixing device G14 is also provided on the fixed platform G12. Through the fixing device G14, the slide making chamber base G40 can be installed above the fixed platform G12, and is located above the slide glass G30 installed on the fixed platform G12. Therefore, the slide glass G30 on each step and the slide making chamber base G40 are equivalent to a thin layer cell smear making device, and one base G11 is equivalent to a plurality of thin layer cell smear making devices. By utilizing the space difference between the slide making chamber G50 and the slide glass G30, the plane space of the slide making frame G10 is reduced, and the three-dimensional space is fully utilized, which is not only convenient for manual operation, but also convenient for the mechanical arm to put in and take away the slide glass when installed on the fully automatic liquid-based cell making machine. The bottom end of the base is the first side end, and the top end is the second side end. The connecting line direction of the first side end and the second side end constitutes the installation direction of the slide glass.

[0041] The glass slide clamping device G13 is used to make it more convenient and accurate to position the glass slide G30 when it is installed on the fixed table G12, and also to make the position of the slide chamber pressed on the glass slide by the slide chamber base G40 accurate. Taking the insertion direction of the glass slide G30 installed on the fixed table G12 as a reference, the glass slide clamping device G13 in this embodiment includes clamping members G13a located on both sides of the fixed table G12 (parallel to the above-mentioned insertion direction) and clamping members G13a in the front (on the side opposite to the insertion end of the glass slide). In one embodiment, the vertical surface of the step is used as the above-mentioned front clamping member, and the glass slide clamping device G13 only includes clamping members G13a located on both sides of the step surface. By setting the clamping members G13a in the front, this embodiment can provide elastic buffering for the glass slide G30 when inserting the glass slide G30, so as to avoid the collision of the glass slide G30 with the vertical surface of the step when inserting, resulting in damage.

[0042] The clamping member G13a may be in various shapes such as a baffle, a positioning strip, an inverted L-shaped clip strip, etc. The material of the clamping member G13a may be plastic, rubber, an elastic rubber strip, etc.

[0043] The base G11 in this embodiment is in the shape of a terrace, and the glass slide clamping device G13 is not only arranged on the inclined surface, but also on the top surface of the base G11. That is, the top surface of the base G11 and the inclined surface together form a three-dimensional multi-level step.

[0044] The fixing device G14 is related to the structure of the film-making chamber base G40, and the fixing device G14 may include: slots provided on the side walls of the base, pins provided on the clamping member, positioning blocks provided on the stepped surface of the base, etc. For example: when the film-making chamber base is installed on the step, if its side walls extend downward to form a boss, the boss can be fixed to the side walls of the base through the slots on the side walls of the base to achieve the fixing of the film-making chamber base; if slots are provided on the bottom wall of the film-making chamber base, the pins provided on the clamping member can cooperate with the slots on the bottom wall of the film-making chamber base to achieve the fixing of the film-making chamber base.

[0045] In one embodiment, Figure 3 As shown, the fixing device G14 includes a mounting hole G14a and a positioning column G14b. The mounting hole G14a is a slot on the side wall of the base G11 and is located below the step; the number of the above-mentioned mounting holes G14a under each step is not limited, and can be one or more; the positioning column G14b is set at the top of the clamping member G13a on the step surface, and the positioning column G14b cooperates with the slot on the bottom wall of the film making chamber base G40. By designing the positioning column G14b and the mounting hole G14a, the film making chamber base G40 can be fixed from different spatial dimensions, ensuring that the film making chamber base G40 is stably and accurately installed on the fixing table G12.

[0046] In order to make the film making chamber installation G40 more stable, further, two positioning columns G14b are arranged at intervals on the clamping member G13a on each side, and the cross section of the positioning column G14b is designed to be trapezoidal.

[0047] In another embodiment, Figure 1 As shown, the fixing device G14 includes a mounting hole G14a and a positioning pin G14c arranged on the side wall of the base G11. The mounting hole G14a and the positioning pin G14c ensure that the film chamber base G40 is stably mounted on the fixing table G12.

[0048] In order to conveniently fix the base G11 on the workbench, the side wall of the base G11 is hollowed out to form a hollow area, and then a plurality of threaded holes G15 are provided on the bottom wall of the base G11, so that the base G11 can be conveniently fixed on the workbench by fasteners through the hollow area.

[0049] like Figure 5 , Figure 6 and Figure 7As shown, in order to facilitate the insertion or removal of slides during manual staining and preparation, as well as to facilitate the cleaning of the base, etc. In one example, a slot G16 is provided at the front end of the bottom wall of the base G11 for the insertion of fasteners such as screws or bolts on the workbench. The slot G16 is arranged in a vertical direction, and a horizontal channel is also dug in the bottom wall of the base G11, and the channel is connected to the slot G16, that is, the slot and the channel are arranged orthogonally. A spring pin G17 is installed in the channel, and a pin shaft G17a is provided on the spring pin G17, which can be engaged with the fastener G17b in the slot G16. When the spring pin G17 is pulled, the spring pin G17 is separated from the fastener G17b. When the spring pin G17 is released, the spring pin G17 is re-engaged with the fastener G17b under the action of the spring rebound force. Therefore, when the base G11 is hingedly mounted on the workbench and the bottom wall of the base G11 is not fixed to the workbench by threads, by pulling the spring pin G17 and removing the clamping connection between the spring pin G17 and the fastener G17b in the slot G16, the base G11 can be lifted, making it more convenient to clean or take or insert the slide G30.

[0050] In this embodiment, six bases G11 are arranged side by side. Figure 6 As shown, a positioning groove G18 is provided on the upper and lower back sides of the base G11, and a positioning groove G18 is fixed on the work surface. Figure 8 The fixing frame G20 shown is frame-shaped and includes an upper frame and a lower frame. Six positioning posts G21 cooperating with the positioning grooves G18 are arranged on the upper frame, and six positioning posts G21 cooperating with the positioning grooves G18 are also arranged on the lower frame. The positioning posts G21 cooperating with the positioning grooves G18 form a hinge mechanism. When the spring pin G17 is pulled, the base G11 can be lifted up with the help of the hinge mechanism. Since the bottom wall of the base G11 is not fixed on the work surface by a fixing part, the positioning posts G21 cooperating with the positioning grooves G18 of the lower frame can make the base G11 more stable when it is placed flat.

[0051] The fixing frame G20 is not limited to the structure of this embodiment. In one example, the fixing frame G20 is provided with only one crossbar, and six positioning posts G21 are arranged at intervals on the crossbar.

[0052] The left and right ends of the fixing frame G20 are provided with flanges G22 perpendicular to the plane where the fixing frame G20 is located, and the shape of the entire fixing frame G20 is similar to "C". The flanges G22 on both sides can clamp the bases G11 on both sides of the side-by-side bases, and can fix the side-by-side bases G11 more firmly.

[0053] Based on the above single base or side-by-side base embodiments, the slide rack G10 may further include a plurality of slide chamber bases G40 provided with through holes for slide chambers to be inserted, and then the slide chamber bases G40 are fixed on the top of the fixed platform G12 through the fixing device G14. When the slide glass G30 is inserted into the slide clamping device G13 on the fixed platform G12, the slide glass G30 is located below the slide chamber base G40. After the slide chamber G50 is installed on the slide chamber base G40, the slide glass G30 seals the bottom end of the slide chamber G50 to prevent leakage of the cell fluid in the slide chamber G50, and the cells can naturally settle on the slide glass G30.

[0054] like Fig. 9 As shown, a through hole G41 is provided at the center of the film making chamber base G40 in this embodiment, and the film making chamber G50 can be pressed into and snapped into the through hole G41. Both sides of the bottom wall of the film making chamber base G40 extend downward to form bosses G42, and a clearance gap G43 is formed between the two bosses G42. When the film making chamber base G40 is fixed on the step, the fixing platform G12 is just in the clearance gap G43. The side wall of the base G11 is provided with mounting holes G14a, and the fasteners fix the bosses G42 on both sides to the side wall of the base G11 through the threaded holes G44, thereby completing the fixing of the film making chamber base G40. Obviously, the fixing device G14 may include not only the above-mentioned mounting holes, but also various other positioning components arranged on the base, such as pins and positioning columns.

[0055] The effect of using the film rack is as follows Fig.10 and Fig.11 shown.

[0056] In summary, the slide rack is designed to be trapezoidal, a slide clamping device is provided on each step, and a fixing device for fixing the slide chamber base is provided, and the slide and the slide chamber base together form a set of slide making devices. By designing each set of slide making devices on the steps, the space difference between the slide chamber and the slide is utilized, and the plane space of the slide rack is greatly reduced. The maximum utilization effect can be achieved in a limited area, and the slide chamber can be installed more conveniently and easily.

[0057] 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.
