[0002] In assisted reproductive technology (ART) laboratories, a couple typically provides multiple embryos for embryologists to monitor their development and select the best ones for transfer back to the mother. In practice, multiple embryos from the same couple are cultured in the same transparent culture dish. To facilitate management, each embryo needs to be labeled. The common practice is for staff to use a scriber to mechanically and destructively mark different areas (usually numbers or words) on the bottom of the transparent plastic culture dish, and then place the different embryos in droplets next to the corresponding marks on the bottom inside the dish. However, this method is inconvenient, inefficient, and time-consuming. Utility Model Content

[0037] In related technologies, an embryo culture dish is a laboratory instrument specifically designed for the in vitro culture of early embryos. It is used to support the development of an embryo from fertilization to the target developmental stage or for transfer back to the mother under strictly controlled environmental conditions.

[0038] In assisted reproductive technology (ART) laboratories, a couple typically provides multiple embryos for embryologists to monitor their development and select the best ones for transfer back to the mother. In practice, multiple embryos from the same couple are cultured in the same transparent culture dish. To facilitate management, each embryo needs to be labeled. The common practice is for staff to use a scriber to mechanically and destructively mark different areas (usually numbers or words) on the bottom of the transparent plastic culture dish, and then place the different embryos in droplets next to the corresponding marks on the bottom inside the dish. However, this method is inconvenient, inefficient, and time-consuming.

[0039] like Figure 1 and Figure 3 As shown, in order to solve the above-mentioned technical problems, Embodiment 1 of this application provides a petri dish, which includes a dish body 100 and a first transparent label. The first transparent label is connected to the dish body 100 and has multiple different first markings 220. The multiple first markings 220 are distributed on the dish body 100 so that the portion of the dish body 100 close to the first markings 220 can form a calibration area 210, and the calibration area 210 is located outside the coverage area of ​​the first transparent label.

[0040] This embodiment uses a cylindrical culture dish as an example. A first transparent label is attached to the dish body 100, forming multiple marking areas 210 inside the dish body 100. Staff can then drop liquid into these marking areas 210 to form droplets for placing embryos. Since the first marker 220 of each marking area 210 is different, it facilitates identification and recording by medical personnel. Furthermore, because the first transparent label is transparent, it does not interfere with observation of the contents of the dish body 100.

[0041] For example, the first marker 220 is a lowercase Arabic numeral. Of course, in other embodiments, the first marker 220 may also be an uppercase Arabic numeral, a lowercase letter, an uppercase letter, etc., and no specific limitation is made here.

[0042] Of course, the first marker 220 can also be set to various colors. For example, the first marker 220 is set to black. In other embodiments, it can also be set to green, gray, etc.

[0043] It should be noted that the density of the multiple first markers 220 should be set to facilitate easy differentiation and observation. That is, the density of the multiple first markers 220 should not be set too densely, as this would make them difficult to see or cause confusion. Of course, the density of the multiple first markers 220 should not be set too sparsely either, as this would reduce the number of embryos that can be accommodated in a single culture dish.

[0044] In addition, since the calibration area 210 is not covered by the first transparent label, the light transmittance is guaranteed when observed under instruments such as microscopes, which helps to improve the accuracy of observation.

[0045] The culture dish provided by this invention, using a first transparent label in conjunction with the dish body 100, replaces the traditional manual cutting method. By dripping liquid and placing embryos in the calibration area 210 defined by the first label 220, the calibration efficiency can be effectively improved, saving time and effort. Secondly, it avoids the generation of plastic particles floating in the air during the manual cutting process, which will eventually adhere to the inner surface of the dish body 100 and mix into the embryo culture medium. Furthermore, it solves the problem of inconsistent cutting quality due to individual differences in the manual cutting method, and avoids the problem that if the labeling information is incorrect due to some kind of operation, the already cut culture dish cannot be corrected and can only be recut using the correct labeling information and a new blank culture dish, which causes a certain amount of waste.

[0046] like Figure 1 As shown, in some embodiments, the first transparent label includes a first label 200, which is connected to the bottom of the dish body 100. The first label 200 has multiple different first markings 220, which are distributed on the bottom of the dish body 100 so that multiple spaced-apart calibration areas 210 can be formed on the bottom of the dish body 100. The first label 200 has a notch 230 at the location of the calibration area 210, and the calibration area 210 is within the coverage area of ​​the corresponding notch 230.

[0047] In other words, the first label 200 is installed on the bottom of the dish body 100, thereby forming multiple calibration areas 210 within the bottom area of ​​the dish body 100.

[0048] For example, the dish body 100 is set to be cylindrical, the first label 200 is set to be circular and adapted to the bottom of the dish body 100, and a plurality of first marks 220 are distributed within the circular range of the first label 200, and the first marks 220 can be observed when viewed from the opening of the dish body 100 towards the bottom.

[0049] In other words, multiple notches 230 are set in the first transparent label, and each of the multiple notches 230 corresponds one-to-one with a multiple first marker 220. That is to say, the calibration area 210 is formed at the notch 230, thereby avoiding the first transparent label from obstructing the observation of the sample.

[0050] In some embodiments, the first transparent label includes a plurality of first labels 200, each of the first labels 200 being provided with a first mark identifier 220, and the first mark identifier 220 on all the first labels 200 being different.

[0051] In other words, the first transparent label can be set as multiple independent first labels 200, which can be attached to the bottom of the dish body 100 respectively. This method can also form a marking area 210 on the bottom of the dish body 100.

[0052] For example, the first label 200 is set to a circle; of course, in other embodiments, it can also be set to a square, ellipse, triangle, etc., without specific limitation here.

[0053] like Figure 2 and Figure 4 As shown, Embodiment 2 of this application provides a petri dish, wherein the first transparent label includes a second label 300, the second label 300 being connected to the side wall of the dish body 100, so that a plurality of calibration areas 210 are formed in the circumferential direction at the bottom of the dish body 100.

[0054] In other words, in this embodiment, by providing a second label 300 on the side wall of the dish body 100, a calibration area 210 corresponding to the first mark 220 on the side wall of the dish body 100 can be formed circumferentially at the bottom of the dish body 100. In other words, the calibration area 210 defined by the second label 300 is sequentially arranged along the circumference of the dish body 100.

[0055] Obviously, the second label 300 can be used to culture a small number of embryos. When there are more embryos, the first label 200 and the second label 300 are used together. That is, the first label 220 is distributed on the side wall and bottom of the dish 100, which can avoid the first label 220 on the bottom of the dish 100 being too densely arranged, making it easier for staff to observe.

[0056] For example, the second label 300 is configured as a strip and extends circumferentially along the dish body 100.

[0057] For example, in other embodiments, when the first label 200 and the second label 300 are used simultaneously, the first label 200 and the second label 300 are integrated, and their bottoms are connected to form a cylindrical container. Specifically, during installation, the bottom of the dish body 100 is simply placed into the cylindrical container and fixed, which facilitates installation. Of course, in other embodiments, the first label 200 and the second label 300 can also be configured separately.

[0058] like Figure 1 As shown, in some embodiments, the first transparent label is detachably attached to the dish body 100.

[0059] In other words, after the petri dish is used, it can be reused by removing the first transparent label from the dish body 100 and then cleaning and disinfecting it. Compared to traditional methods of marking petri dishes, this saves costs and enables resource reuse.

[0060] It should be noted that you only need to replace the first transparent label when reusing it.

[0061] Of course, in other embodiments, the first transparent label can also be made reusable to further reduce costs.

[0062] In some embodiments, a first transparent label is adhered to the dish body 100.

[0063] For example, applying adhesive to the first transparent label to bond it to the dish body 100 is convenient and quick, and the adhesive can reduce the amount of air bubbles between the first transparent label and the dish body 100, which is beneficial for observation. Of course, in other embodiments, an adhesive layer can also be provided on the first transparent label, eliminating the need to apply adhesive; the release paper on the adhesive layer can be peeled off for bonding.

[0064] To facilitate the recycling of the container 100, the adhesive can be a non-adhesive adhesive.

[0065] In some embodiments, the first transparent label is electrostatically or vacuum-adsorbed onto the dish 100.

[0066] In other words, electrostatic or vacuum adsorption forces can be formed between the first transparent label and the dish body 100, thus eliminating the need for adhesive bonding, reducing costs, and making it easier to install and remove the first transparent label.

[0067] like Figure 1 and Figure 2As shown, in some embodiments, when the first label 200 is adhered to the bottom of the dish body 100, the bottom of the dish body 100 has opposing inner and outer surfaces, the inner surface is located inside the dish body 100, and the first transparent label has an adhesive surface.

[0068] The adhesive surface of the first label 200 is adhered to the outer side, and the first mark 220 is mirror-flipped so that the first mark 220 is facing forward from the direction of the inner and outer sides.

[0069] It should be noted that when the first label 200 is adhered to the outer side, if the first mark 220 is positioned facing forward on the first label 200, then when viewed from the inner and outer sides, the first mark 220 appears to be reversed, making it inconvenient for staff to observe. Therefore, by mirror-flipping the first mark 220, it appears to be facing forward when viewed from the inner and outer sides.

[0070] In some embodiments, when the first label 200 is attached to the outer side, the first label 200 protrudes from the bottom of the dish body 100.

[0071] By adjusting the thickness of the first label 200, it can form multiple support portions to support the dish body 100. When the first label 200 is adhered to the bottom of the dish body 100, the bottom of the dish body 100 contacts the placement platform through the first label 200, thereby reducing wear on the dish body 100. In addition, the flexibility of the first label 200 can prevent hard collisions between the dish body 100 and the placement platform, reducing noise and the risk of bumps.

[0072] like Figure 5 As shown, in some embodiments, the first transparent label includes thermal label paper 400 or thermal transfer label paper, on which the first mark 220 is printed.

[0073] It consists of a computer with an operating system (Windows, Linux, macOS, etc.), a label editing application, a thermal / thermal transfer printer, and transparent thermal / thermal label paper with safety adhesive backing. The label editing application is installed on the computer with the operating system, and the thermal / thermal transfer printer is connected to the computer via a data cable. The transparent thermal / thermal transfer label paper with safety adhesive backing is installed inside the thermal / thermal transfer printer (if thermal transfer labels are used, the matching thermal transfer ribbon is also installed inside the printer). First, the relevant patient information is entered into the label editing application. This can be done for a single patient or multiple patients in batches. Then, the label editing software will generate a mirrored label template based on the input information and create a preview. The size, shape, style, content, layout, font, and color of the label can be selected from preset templates or customized according to actual needs. After previewing and confirming that everything is in order, click "Print" to send the corresponding print information to the thermal / thermal transfer printer. After receiving the print information, the thermal / thermal transfer printer will print the marking information on a transparent thermal / thermal transfer label with a safety adhesive backing. Then, paste the first transparent label with the marking information onto the top or bottom of the transparent petri dish. At this time, the label information pasted on the petri dish can be clearly seen through the front of the petri dish, and the text is clear, neat and easy to identify.

[0074] like Figure 5 As shown, in one embodiment, the thermal label paper 400 includes a backing paper layer 470, a back protective layer 460, a release layer 450, an adhesive layer 440, a face paper layer 430, a thermal layer 420, and a surface protective layer 410 connected in sequence; wherein, a first marking identifier 220 is formed on the thermal layer 420.

[0075] The thermal layer 420 is heated by the printer according to the printed content to display the printed information. It is placed under the surface protective layer 410, which is made of waterproof, oil-proof, wear-resistant and scratch-resistant material, and can protect the marking information of the thermal layer 420 during use.

[0076] If thermal transfer label paper is used, it needs to be used in conjunction with a transfer ribbon. After the ribbon is heated, it transfers the information to be printed onto the thermal transfer label paper. The corresponding thermal transfer ribbon is a high-quality resin-based ribbon, which has the characteristics of super solvent resistance and abrasion resistance, and the printed content is not easily worn away or lost.

[0077] Since the aforementioned thermal label paper 400 and thermal transfer label paper will be pasted on the petri dish, the pasted part is made of non-toxic or low-toxic materials to meet the corresponding biocompatibility requirements.

[0078] In some embodiments, the petri dish further includes a lid that covers the dish body 100; wherein the lid is provided with a second transparent label and the dish body 100 is provided with a third transparent label, the second transparent label having a second marking identifier and the third transparent label having a third marking identifier, and the second marking identifier and the third marking identifier having a corresponding relationship.

[0079] In other words, the correspondence between the second and third markings is used to avoid placing the wrong lid on the current dish body 100.

[0080] For example, the second and third markers may be the same label, which may be a number, a letter, etc.

[0081] Alternatively, both the second and third markers can be patient identification information, such as the patient's name, code, etc.

[0082] In addition, each of the above-mentioned first markers 220 can form a corresponding marking area 210 at the bottom of the dish body 100, and together with the patient's identity information, it is convenient for staff to read the information and make records, reducing the probability of confusion in recording embryo culture information.

[0083] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0084] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0085] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
