[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0034] The following is for reference. Figures 1-5 The present invention describes a delivery device 100 according to an embodiment of the present invention, which may be used, but is not limited to, for gene detection.
[0035] like Figure 1and Figure 3 As shown, the transfer device 100 according to the present invention includes: a transfer chamber 1 and a conveying mechanism 2. The transfer chamber 1 has a first sidewall 11 and a second sidewall 12 that are opposite to and spaced apart along a first direction. The conveying mechanism 2 passes through the first sidewall 11 and the second sidewall 12 along the first direction. One end of the conveying mechanism 2 is adapted to extend into the first chamber, and the other end of the conveying mechanism 2 is adapted to extend into the second chamber. The first sidewall 11 is formed with a first transport port 111 for the sample to be processed to pass through, and the second sidewall 12 is formed with a second transport port 121 for the sample to be processed to pass through. The first transport port 111 and the second transport port 121 are both selectively opened so that the conveying mechanism 2 can transport the sample to be processed from one side of the transfer chamber 1 to the other side of the transfer chamber 1.
[0036] The transfer chamber 1 has a first sidewall 11 and a second sidewall 12, which are arranged opposite to each other along a first direction and are spaced apart. Figure 1 The X direction refers to the length direction of the transfer device. The first and second chambers can be two sealed operating devices in the same laboratory environment or two sealed operating devices in different experimental environments. The first and second chambers are arranged along the first direction and are spaced apart along the first direction. The transfer chamber 1 is located between the first and second chambers, and the conveying mechanism 2 passes through the first side wall 11 and the second side wall 12 along the first direction. This arrangement makes the arrangement of the conveying mechanism 2 reasonable, so that one end of the conveying mechanism 2 extends into the first chamber and the other end extends into the second chamber.
[0037] The first sidewall 11 has a first transport port 111, and the second sidewall 12 has a second transport port 121. Both the first transport port 111 and the second transport port 121 are used for the passage of the sample to be processed. Both the first transport port 111 and the second transport port 121 are selectively opened. For example, the transfer chamber 1 may have two sealing doors, which selectively block the first transport port 111 and the second transport port 121 respectively. When the corresponding sealing door is opened, the corresponding first transport port 111 or the corresponding second transport port 121 is opened. When the corresponding sealing door is closed, the corresponding first transport port 111 or the corresponding second transport port 121 is closed. This arrangement allows both the first transport port 111 and the second transport port 121 to be selectively opened, so that the conveying mechanism 2 can transport the sample to be processed from one side of the transfer chamber 1 to the other side of the transfer chamber 1. This application uses the example of the conveying mechanism 2 transporting the sample to be processed in the first chamber to the second chamber through the transfer chamber 1 for illustration.
[0038] By setting one end of the conveying mechanism 2 to extend into the first chamber and the other end of the conveying mechanism 2 to extend into the second chamber, and by using the conveying mechanism 2 to transport the sample to be processed from one side of the transfer chamber 1 to the other side of the transfer chamber 1, the process between the first chamber and the second chamber can be automated, effectively preventing errors in the test results caused by human error, improving the standardization, normalization and convenience of gene testing, and thus improving the accuracy of the test results.
[0039] Specifically, the first chamber and the second chamber are arranged along a first direction and spaced apart. The transfer chamber 1 is assembled in the space between the first chamber and the second chamber. The conveying mechanism 2 passes through the first side wall 11 and the second side wall 12, with one end of the conveying mechanism 2 extending into the first chamber and the other end extending into the second chamber. The first side wall 11 has a first transport port 111, and the second side wall 12 has a second transport port 121. Both the first transport port 111 and the second transport port 121 are used for the passage of the sample to be processed. Two sealing doors selectively block the first transport port 111 and the second transport port 121, respectively.
[0040] The sample to be processed is placed into the first chamber, where the equipment processes it. After processing, the sealing door corresponding to the first transport port 111 opens. Note that the sealing door corresponding to the second transport port 121 remains closed at this time. The conveying mechanism 2 transports the processed sample from the first chamber to the transfer chamber 1. Once the sample is fully inside the transfer chamber 1, the sealing door corresponding to the first transport port 111 closes. The sealing door corresponding to the second transport port 121 then opens, and the conveying mechanism 2 continues to transport the sample from the transfer chamber 1 to the second chamber, where the equipment performs further processing.
[0041] Therefore, by setting one end of the conveying mechanism 2 to extend into the first chamber and the other end of the conveying mechanism 2 to extend into the second chamber, and by using the conveying mechanism 2 to transport the sample to be processed from one side of the transfer chamber 1 to the other side of the transfer chamber 1, the process between the first chamber and the second chamber can be automated, improving detection efficiency, effectively preventing errors in detection results caused by human error, and improving the accuracy of detection results.
[0042] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, the first transport port 111 and the second transport port 121 are arranged opposite to each other along the first direction.
[0043] Among them, along the first direction, i.e. Figure 1In the X direction, the first transport port 111 and the second transport port 121 are arranged opposite each other. This arrangement makes the arrangement of the first transport port 111 and the second transport port 121 reasonable, and it is beneficial that the arrangement direction of the first transport port 111 and the second transport port 121 is consistent with the direction of the transport mechanism 2 in conveying the sample to be processed. During the transportation of the sample to be processed, the first transport port 111 and the second transport port 121 can reliably avoid the sample to be processed, reducing the risk of interference between the sample to be processed and the first side wall 11 and the second side wall 12 during the transportation process, thereby improving the safety and stability of the transportation of the sample to be processed.
[0044] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, the first sidewall 11 is movably provided with a first sealing door 112, which is used to open or close the first transport port 111; the second sidewall 12 is movably provided with a second sealing door 122, which is used to open or close the second transport port 121.
[0045] The first sidewall 11 is movably provided with a first sealing door 112, which is the sealing door of the above embodiment. In some embodiments of this application, the first sidewall 11 is slidably provided with the first sealing door 112. In some embodiments of this application, the first sidewall 11 is rotatably provided with the first sealing door 112. The first sealing door 112 is used to open or close the first transport port 111. When the first sealing door 112 is open, the first transport port 111 is open, and the transport mechanism 2 can smoothly transport the sample to be processed to the transfer chamber 1 through the first transport port 111. When the first sealing door 112 is closed, the first transport port 111 is closed, reducing the risk of gas exchange between the first chamber and the transfer chamber 1 or between the external environment and the transfer chamber 1, thereby reducing the risk of cross-contamination of the sample to be processed. By movably providing a first sealing door 112 on the first side wall 11, the difficulty of opening and closing the first transport port 111 can be reduced, thereby facilitating the transport of the sample to be processed and enabling the transport mechanism 2 to selectively transport the sample to be processed to the transfer chamber 1 through the first transport port 111.
[0046] The second sidewall 12 is movably provided with a second sealing door 122, which is the sealing door of the above embodiment. In some embodiments of this application, the second sidewall 12 is slidably provided with the second sealing door 122. In some embodiments of this application, the second sidewall 12 is rotatably provided with the second sealing door 122. The second sealing door 122 is used to open or close the second transport port 121. When the second sealing door 122 is open, the second transport port 121 is open, and the transport mechanism 2 can smoothly transport the sample to be processed to the second chamber through the second transport port 121. When the second sealing door 122 is closed, the second transport port 121 is closed, reducing the risk of gas exchange between the second chamber and the transfer chamber 1 or between the external environment and the transfer chamber 1, thereby reducing the risk of cross-contamination of the sample to be processed. By movably providing a second sealing door 122 on the second side wall 12, the difficulty of opening and closing the second transport port 121 can be reduced, thereby facilitating the transport of the sample to be processed and enabling the transport mechanism 2 to selectively transport the sample to be processed to the second compartment through the second transport port 121.
[0047] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, a first sealing door 112 is slidably disposed on a first side wall 11 along a second direction to open or close the first transport port 111; and / or a second sealing door 122 is slidably disposed on a second side wall 12 along a second direction to open or close the second transport port 121, wherein the first direction and the second direction are perpendicular.
[0048] In some embodiments of this application, a first sealing door 112 is slidably disposed on a first side wall 11 along a second direction to open or close the first transport port 111. In some embodiments of this application, a second sealing door 122 is slidably disposed on a second side wall 12 along a second direction to open or close the second transport port 121. In some embodiments of this application, the first sealing door 112 is slidably disposed on a first side wall 11 along a second direction to open or close the first transport port 111, and the second sealing door 122 is slidably disposed on a second side wall 12 along a second direction to open or close the second transport port 121.
[0049] This application describes an example where a first sealing door 112 is slidably disposed on a first side wall 11 along a second direction to open or close the first transport port 111, and a second sealing door 122 is slidably disposed on a second side wall 12 along a second direction to open or close the second transport port 121. Along the second direction, i.e. Figure 2 In the Y direction, which is the height direction of the transmission device, the first sealing door 112 is slidably disposed on the first side wall 11 to open or close the first transport port 111. The first direction and the second direction are perpendicular, that is, the X direction and the Y direction are perpendicular.
[0050] Specifically, along the second direction, when the first sealing door 112 slides upward, the first sealing door 112 opens, and the first transport port 111 opens, allowing the transport mechanism 2 to smoothly transport the sample to be processed to the transfer chamber 1 through the first transport port 111. Along the second direction, when the first sealing door 112 slides downward, the first sealing door 112 closes, and the first transport port 111 closes, reducing the risk of gas exchange between the first chamber and the transfer chamber 1, thereby reducing the risk of cross-contamination of the sample to be processed.
[0051] By setting a first sealing door 112 that can slide along the second direction, the risk of the first sealing door 112 blowing gas from the transfer chamber 1 into the first chamber body can be reduced during the opening or closing of the first sealing door 112, thereby reducing the risk of the sample to be processed in the first chamber body being contaminated, and further reducing the risk of cross-contamination of the sample to be processed.
[0052] Along the second direction, i.e. Figure 2 In the Y direction, which is the height direction of the conveying device, the second sealing door 122 is slidably disposed on the second side wall 12 to open or close the second conveying port 121. The first direction and the second direction are perpendicular, that is, the X direction and the Y direction are perpendicular.
[0053] Specifically, when the second sealing door 122 slides upward along the second direction, it opens, and the second transport port 121 opens, allowing the transport mechanism 2 to smoothly transport the sample to be processed to the second chamber through the second transport port 121. When the second sealing door 122 slides downward along the second direction, it closes, and the second transport port 121 closes, reducing the risk of gas exchange between the second chamber and the transfer chamber 1, thereby reducing the risk of cross-contamination of the sample to be processed.
[0054] By setting a second sealing door 122 that can slide along the second direction, the risk of the second sealing door 122 blowing gas from the transfer chamber 1 into the second chamber can be reduced during the opening or closing of the second sealing door 122, thereby reducing the risk of the sample to be processed in the second chamber being contaminated, and further reducing the risk of cross-contamination of the sample to be processed.
[0055] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, the first sidewall 11 also has a first assembly hole (not shown in the figure), the first assembly hole and the first conveying port 111 are adjacent to and connected along the second direction, the second sidewall 12 also has a second assembly hole, the second assembly hole and the second conveying port 121 are adjacent to and connected along the second direction, the first assembly hole and the second assembly hole are opposite to each other along the first direction, and the conveying mechanism 2 passes through the first assembly hole and the second assembly hole, the first direction and the second direction are perpendicular.
[0056] The first sidewall 11 also has a first assembly hole. Along the second direction, the first assembly hole and the first transport port 111 are adjacent and connected. The second sidewall 12 also has a second assembly hole. Along the second direction, the second assembly hole and the second transport port 121 are adjacent and connected. The first assembly hole and the second assembly hole are arranged opposite each other along the first direction. This arrangement allows for a reasonable arrangement of the first and second assembly holes, facilitating smooth passage of the conveying mechanism 2. This reduces the risk of interference between the conveying mechanism 2 and the first sidewall 11 and the second sidewall 12 during the assembly of the transfer device 100. The first and second directions are perpendicular, meaning the X and Y directions are perpendicular.
[0057] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, the second direction is the vertical direction, the first assembly hole is located below the first transport port 111, and the second assembly hole is located below the second transport port 121.
[0058] The second direction is the up-down direction, i.e. Figure 1 In the Y direction, the first assembly hole is located below the first transport port 111, and the second assembly hole is located below the second transport port 121. This arrangement ensures that the positions of the first assembly hole and the first transport port 111 are reasonable, and the positions of the second assembly hole and the second transport port 121 are also reasonable. During the transportation of the sample to be processed, the conveying mechanism 2 passes through the first assembly hole and the second assembly hole, and the sample to be processed passes through the first transport port 111 and the second transport port 121. By placing the first assembly hole below the first transport port 111 and the second assembly hole below the second transport port 121, the conveying mechanism 2 can always carry the sample to be processed below it, reducing the risk of the sample tipping over and further improving the safety and stability of the sample transportation process.
[0059] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, along the third direction, the two conveying mechanism sidewalls 21 of the conveying mechanism 2 are both sealed to the first sidewall 11 and the second sidewall 12, and the first direction, the second direction and the third direction are perpendicular to each other.
[0060] Along the third direction, i.e., the Z direction in the figure, which is the width direction of the transfer device, the conveying mechanism 2 has two conveying mechanism side walls 21. Both conveying mechanism side walls 21 are sealed to the first side wall 11 and the second side wall 12. For example, foam sealing rings, silicone sealing rings, rubber sealing rings, etc. can be set in the gap between the two conveying mechanism side walls 21 and the first side wall 11 and the second side wall 12 to achieve a sealing effect between the two conveying mechanism side walls 21 and the first side wall 11 and the second side wall 12. This reduces the risk of external air entering the transfer chamber 1 or the first chamber body through the gap between the conveying mechanism 2 and the first side wall 11 or the gap between the conveying mechanism 2 and the second side wall 12 during the transport of the sample to be processed. This reduces the risk of the sample to be processed being contaminated during transport and helps to improve the accuracy of the test results.
[0061] In some examples of this utility model, such as Figures 1-3 As shown, the first sealing door 112 and / or the second sealing door 122 have an abutment end 3 facing the conveying mechanism 2, and the abutment end 3 is fixedly provided with a first sealing element 31, which is adapted to abut and seal with the conveying mechanism 2.
[0062] In some embodiments of this application, the first sealing door 112 has an abutment end 3 facing the conveying mechanism 2. In some embodiments of this application, the second sealing door 122 has an abutment end 3 facing the conveying mechanism 2. In some embodiments of this application, both the first sealing door 112 and the second sealing door 122 have an abutment end 3 facing the conveying mechanism 2.
[0063] This application describes an example where both the first sealing door 112 and the second sealing door 122 have an abutment end 3 facing the conveying mechanism 2. Along the second direction, the lower ends of the first sealing door 112 and the second sealing door 122 are the abutment ends 3. The abutment end 3 is fixedly provided with a first sealing element 31. For example, the first sealing element 31 may be fixed to the first sealing element 31 by means of bolts, adhesives, etc. The first sealing element 31 may be made of materials such as rubber, silicone, or foam. When the first sealing door 112 closes the first transport port 111 and the second sealing door 122 closes the second transport port 121, the first sealing element 31 abuts against the transport mechanism 2 to seal the gap between the transport mechanism 2 and the first sealing door 112 and the gap between the transport mechanism 2 and the second sealing door 122. This reduces the risk of gas exchange between the first chamber and the transfer chamber 1 when the first sealing door 112 closes the first transport port 111, and also reduces the risk of gas exchange between the second chamber and the transfer chamber 1 when the second sealing door 122 closes the second transport port 121, thereby reducing the risk of contamination of the sample to be processed in the first or second chamber.
[0064] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, a sealing structure 4 is fixed on the surface of the first sidewall 11 facing away from the second sidewall 12 and / or the surface of the second sidewall 12 facing away from the first sidewall 11. The sealing structure 4 on the first sidewall 11 is arranged around the first transport port 111 in the circumferential direction, and the sealing structure 4 on the second sidewall 12 is arranged around the second transport port 121 in the circumferential direction.
[0065] In some embodiments of this application, a sealing structure 4 is fixedly provided on the surface of the first sidewall 11 facing away from the second sidewall 12. In some embodiments of this application, a sealing structure 4 is fixedly provided on the surface of the second sidewall 12 facing away from the first sidewall 11. In some embodiments of this application, a sealing structure 4 is fixedly provided on the surface of the first sidewall 11 facing away from the second sidewall 12, and a sealing structure 4 is fixedly provided on the surface of the second sidewall 12 facing away from the first sidewall 11.

This effectively reduces the risk of the sample to be processed being contaminated during transportation, thereby improving the accuracy of the test results.
[0068] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, the sealing structure 4 may include: a second seal 41 and a third seal 42. The second seal 41 on the first sidewall 11 is arranged around the first transport port 111, and the third seal 42 on the first sidewall 11 is located on the side of the second seal 41 away from the first transport port 111 and is arranged around the second seal 41. The second seal 41 on the second sidewall 12 is arranged around the second transport port 121, and the third seal 42 on the second sidewall 12 is located on the side of the second seal 41 away from the second transport port 121 and is arranged around the second seal 41.
[0069] The second sealing element 41 and the third sealing element 42 can be, but are not limited to, made of materials such as rubber, silicone, or foam. When the first chamber and the transfer chamber 1 are assembled, the second sealing element 41 abuts against both the first side wall 11 and the side wall of the first chamber. As some embodiments of this application, one end of the second sealing element 41 along the first direction can be provided with a double-sided adhesive strip. The end of the second sealing element 41 with the double-sided adhesive strip is bonded to the first side wall 11, and the end of the second sealing element 41 without the double-sided adhesive strip abuts against the side wall of the first chamber, so that the second sealing element 41 seals the gap between the first side wall 11 and the side wall of the first chamber.
[0070] As some embodiments of this application, the second sealing member 41 may be provided with double-sided adhesive strips at both ends along the first direction, and the two ends of the second sealing member 41 along the first direction are respectively bonded to the first sidewall 11 and the sidewall of the first chamber, so that the second sealing member 41 seals the gap between the first sidewall 11 and the sidewall of the first chamber. The second sealing member 41 is arranged around the first transport port 111 in the circumferential direction. This arrangement can make the seal between the first chamber and the transfer chamber 1 reliable. During the opening of the first sealing door 112, the risk of external air entering the first chamber or the transfer chamber 1 through the gap between the first chamber and the transfer chamber 1 can be reduced, further reducing the risk of the sample to be processed being contaminated during transportation, and further improving the accuracy of the test results.
[0071] The third sealing member 42 abuts against both the first sidewall 11 and the first compartment sidewall. As some embodiments of this application, one end of the third sealing member 42 along the first direction may be provided with a double-sided adhesive strip. The end of the third sealing member 42 with the double-sided adhesive strip is bonded to the first sidewall 11, and the end of the third sealing member 42 without the double-sided adhesive strip abuts against the first compartment sidewall, so that the third sealing member 42 seals the gap between the first sidewall 11 and the first compartment sidewall.

[0073] The third seal 42 is located on the side of the second seal 41 away from the first transport port 111, and the third seal 42 is arranged around the second seal 41 circumferentially. This arrangement makes the seal between the first chamber and the transfer chamber 1 more reliable. During the opening of the first sealing door 112, the second seal 41 and the third seal 42 jointly seal between the first side wall 11 and the side wall of the first chamber, preventing ambient air from entering or leaving the transfer device through the gap between the first side wall 11 and the side wall of the first chamber to the greatest extent possible. This further reduces the risk of contamination of the sample during transportation and further improves the accuracy of the test results.
[0074] When the second chamber and the transfer chamber 1 are assembled, the second seal 41 abuts against both the second side wall 12 and the side wall of the second chamber. As some embodiments of this application, one end of the second seal 41 along the first direction may be provided with a double-sided adhesive strip. The end of the second seal 41 with the double-sided adhesive strip is bonded to the second side wall 12, and the end of the second seal 41 without the double-sided adhesive strip abuts against the side wall of the second chamber, so that the second seal 41 seals the gap between the second side wall 12 and the side wall of the second chamber.
[0075] As some embodiments of this application, the second sealing member 41 may be provided with double-sided adhesive strips at both ends along the first direction, and the two ends of the second sealing member 41 along the first direction are respectively bonded to the second side wall 12 and the second chamber side wall, so that the second sealing member 41 seals the gap between the second side wall 12 and the second chamber side wall. The second sealing member 41 is arranged around the second transport port 121 in the circumferential direction. This arrangement can make the seal between the second chamber and the transfer chamber 1 reliable. During the opening of the second sealing door 122, the risk of external air entering the second chamber or the transfer chamber 1 through the gap between the second chamber and the transfer chamber 1 can be reduced, further reducing the risk of the sample to be processed being contaminated during transportation, and further improving the accuracy of the test results.
[0076] The third sealing member 42 abuts against both the second side wall 12 and the second compartment side wall. As some embodiments of this application, one end of the third sealing member 42 along the first direction may be provided with a double-sided adhesive strip. The end of the third sealing member 42 with the double-sided adhesive strip is bonded to the second side wall 12, and the end of the third sealing member 42 without the double-sided adhesive strip abuts against the second compartment side wall, so that the third sealing member 42 seals the gap between the second side wall 12 and the second compartment side wall.
[0077] As some embodiments of this application, the third sealing member 42 may be provided with double-sided adhesive strips at both ends along the first direction, and the third sealing member 42 is bonded to the second side wall 12 and the second compartment side wall at both ends along the first direction, so that the third sealing member 42 seals the gap between the second side wall 12 and the second compartment side wall.
[0078] The third seal 42 is located on the side of the second seal 41 away from the second transport port 121, and the third seal 42 is arranged around the second seal 41 circumferentially. This arrangement makes the seal between the second chamber and the transfer chamber 1 more reliable. During the opening of the second sealing door 122, the second seal 41 and the third seal 42 jointly seal between the second side wall 12 and the second chamber side wall, preventing ambient air from entering or leaving the transfer device through the gap between the second side wall 12 and the second chamber side wall to the greatest extent possible. This further reduces the risk of contamination of the sample during transportation and further improves the accuracy of the test results.
[0079] In some examples of this utility model, such as Figure 1 and Figure 3 As shown, the third sealing element 42 may include: a first sub-sealing strip 421, a second sub-sealing strip 422 and a third sub-sealing strip 423. The second sub-sealing strip 422 is connected between the first sub-sealing strip 421 and the third sub-sealing strip 423. The first sub-sealing strip 421 and the third sub-sealing strip 423 both extend along the second direction and are respectively disposed on opposite sides of the conveying mechanism 2 along the third direction. Along the second direction, the second sub-sealing strip 422 is disposed on the side of the corresponding first conveying port 111 or second conveying port 121 away from the conveying mechanism 2. The first direction, the second direction and the third direction are perpendicular to each other.
[0080] The second sub-sealing strip 422 is connected between the first sub-sealing strip 421 and the third sub-sealing strip 423. The first sub-sealing strip 421, the second sub-sealing strip 422, and the third sub-sealing strip 423 can be connected by, but is not limited to, integral molding or bonding. Furthermore, both the first sub-sealing strip 421 and the third sub-sealing strip 423 extend along a second direction, and are respectively disposed on opposite sides of the conveying mechanism 2 along a third direction. Further, the first sub-sealing strip 421 and the third sub-sealing strip 423 are respectively disposed on two opposite side edges of the first sidewall 11 or the second sidewall 12 along a third direction. The second sub-seal strip 422 extends along a third direction and along a second direction. The second sub-seal strip 422 is disposed on the side of the corresponding first conveying port 111 or second conveying port 121 away from the conveying mechanism 2. Furthermore, the second sub-seal strip 422 is disposed on the upper edge of the first side wall 11 or the second side wall 12. This arrangement makes the arrangement of the third seal 42 more reasonable, facilitating reliable sealing of the gap between the first side wall 11 and the first chamber side wall from the periphery of the first side wall 11, thus improving the sealing effect of the third seal 42. The first direction, the second direction, and the third direction are perpendicular to each other; that is, the X direction, Y direction, and Z direction are perpendicular to each other.
[0081] In some examples of this utility model, such as Figures 1-3 As shown, the third sealing element 42 also has a fourth sub-sealing strip 424 and a fifth sub-sealing strip. Along the third direction, the fourth sub-sealing strip 424 and the fifth sub-sealing strip are located on both sides of the conveying mechanism 2. Along the second direction, the end of the first sub-sealing strip 421 facing away from the second sub-sealing strip 422 is connected to the fourth sub-sealing strip 424, and the end of the third sub-sealing strip 423 facing away from the second sub-sealing strip 422 is connected to the fifth sub-sealing strip. The fourth sub-sealing strip 424 and the fifth sub-sealing strip both extend along the third direction and are located on the side of the corresponding first conveying port 111 or second conveying port 121 facing away from the second sub-sealing strip 422. The fourth sub-sealing strip 424 and the fifth sub-sealing strip abut against the two conveying mechanism sidewalls 21 of the conveying mechanism 2 along the third direction for sealing.
[0082] Among them, along the third direction, that is Figure 1 In the Z direction, the first sub-seal strip 421 and the third sub-seal strip 423 are located on both sides of the conveying mechanism 2. In the second direction, the end of the first sub-seal strip 421 away from the second sub-seal strip 422 is connected to the fourth sub-seal strip 424, that is, the lower end of the first sub-seal strip 421 is connected to the fourth sub-seal strip 424. The end of the third sub-seal strip 423 away from the second sub-seal strip 422 is connected to the fifth sub-seal strip, that is, the lower end of the third sub-seal strip 423 is connected to the fifth sub-seal strip, so that the fourth sub-seal strip 424 and the fifth sub-seal strip are located on both sides of the conveying mechanism 2.
[0083] Both the fourth sub-seal strip 424 and the fifth sub-seal strip extend along a third direction, and are positioned on the side of the corresponding first conveying port 111 or second conveying port 121 away from the second sub-seal strip 422, i.e., the lower edge of the first side wall 11. Along the third direction, the fourth sub-seal strip 424 and the fifth sub-seal strip respectively abut and seal against the two side walls 21 of the conveying mechanism 2 along the third direction. This arrangement further optimizes the arrangement of the third seal 42, facilitating the sealing of the gap between the first side wall 11 and the first chamber side wall at the outer edge of the first side wall 11, thus further improving the sealing effect of the third seal 42.
[0084] In some examples of this utility model, such as Figure 4As shown, the conveying mechanism 2 includes a drive mechanism 22, a guide rail 23, and a placement platform 24. The guide rail 23 passes through the first side wall 11 and the second side wall 12, and both ends of the guide rail 23 are adapted to extend into the first chamber and the second chamber, respectively. The placement platform 24 is located outside the guide rail 23 and is used to place the sample to be processed. At least a part of the drive mechanism 22 is located inside the guide rail 23 and is connected to the placement platform 24 in a transmission manner. The drive mechanism 22 is used to drive the placement platform 24 to reciprocate relative to the guide rail 23 in a first direction, so that the placement platform 24 transports the sample to be processed from one side of the transfer chamber 1 through the transfer chamber 1 to the other side of the transfer chamber 1.
[0085] The guide rail 23 extends along a first direction and passes through the first sidewall 11 and the second sidewall 12. Both ends of the guide rail 23 extend into the first and second compartments respectively. The placement table 24 is located outside the guide rail 23 to facilitate the placement of samples to be processed by personnel. At least a portion of the drive mechanism 22 is located within the guide rail 23; for example, a portion of the drive mechanism 22 may be located within the guide rail 23, or the entire structure of the drive mechanism 22 may be located within the guide rail 23. The drive mechanism 22 is connected to the placement table 24 so that it can drive the placement table 24 to reciprocate relative to the guide rail 23 along the first direction. This allows the placement table 24 to transport the samples to be processed from one side of the transfer compartment 1 to the other side. When the transfer compartment 1 is installed between the first and second compartments, it facilitates the smooth movement of the placement table 24 into one of the first, second, and transfer compartments, thereby sequentially processing the samples within the placement table 24.
[0086] In some examples of this utility model, such as Figure 4 and Figure 5 As shown, the guide rail 23 has a guide rail wall 231 facing the placement platform 24. The guide rail wall 231 forms a clearance hole extending along a first direction. The drive mechanism 22 includes a drive rod 221, which passes through the clearance hole. The clearance hole is provided with a sixth sealing member 5, which is used to seal the clearance hole. The sixth sealing member 5 includes a first sealing strip 51 and a second sealing strip 52. The first sealing strip 51 and the second sealing strip 52 both extend along the first direction and are located on both sides of the drive rod 221. The first sealing strip 51 and the second sealing strip 52 both abut against the drive rod 221 for sealing.
[0087] The guide rail 23 has a guide rail wall 231, which forms a side wall of the guide rail 23 facing the placement platform 24. The guide rail wall 231 has a clearance hole extending in a first direction, which can allow the drive mechanism 22 to pass through. Furthermore, the drive mechanism 22 includes a drive rod 221, which passes through the clearance hole so that the drive rod 221 can be fixedly connected to the placement platform 24, thereby achieving the effect of the drive mechanism 22 driving the placement platform 24 to move via the drive rod 221. The clearance hole is provided with a sixth seal 5, which may be, but is not limited to, made of rubber, silicone, foam, etc. The sixth seal 5 is used to seal the clearance hole, reducing the risk of external air entering the first compartment, the second compartment, or the transfer compartment 1 through the clearance hole.
[0088] The sixth sealing element 5 includes a first sealing strip 51 and a second sealing strip 52. Both the first sealing strip 51 and the second sealing strip 52 extend along a first direction. Along a third direction, the first sealing strip 51 and the second sealing strip 52 are located on both sides of the drive rod 221, and both the first sealing strip 51 and the second sealing strip 52 abut against the drive rod 221 to seal, so as to reduce the risk of external air entering the first compartment, the second compartment or the transfer compartment 1 through the gap between the drive rod 221 and the guide rail wall 231 when the drive rod 221 moves along the first direction.
[0089] like Figure 5 As shown, the guide rail 23 can also be fixed with two pressure strips 233. The pressure strips 233 are respectively fixed to the ends of the first sealing strip 51 and the second sealing strip 52 that are away from each other. The first sealing strip 51 and the second sealing strip 52 are made of elastic materials, such as rubber or silicone. By setting the pressure strips 233, the first sealing strip 51 and the second sealing strip 52 can be interference-fitted between the corresponding pressure strip and the drive rod 221, which not only improves the sealing effect of the first sealing strip 51 and the second sealing strip 52, but also further improves the sealing effect of the transmission device 100, and ensures that the drive rod 221 slides smoothly.
[0090] The first sealing strip 51 and the second sealing strip 52 do not affect the back-and-forth movement of the drive rod 221, and can maintain the relative stability of the height of the placement platform 24, avoiding the swaying of the guide rail 23 due to excessive friction, which would affect the accuracy of the height of the placement platform 24. This design ensures the smoothness of the drive mechanism 22 during operation, and at the same time, it precisely fills the gap in the transmission direction of the guide rail 23, preventing air exchange between the first chamber, the second chamber, or the transfer chamber 1 and the outside. In addition, the sixth sealing element 5 inside the guide rail 23 is in close contact with the rubber strip at the bottom of the first sealing door 112 and the second sealing door 122 of the transfer chamber 1, which can effectively prevent airflow between the first chamber, the second chamber, or the transfer chamber 1.
[0091] Furthermore, the guide rail 23 can also support the placement stage 24. The guide rail 23 may have a fixed base 232. By adjusting the height of the fixed base 232 at the bottom of the guide rail 23, the placement stage 24 can remain horizontal at both ends of the guide rail 23 along the first direction (i.e., within the first or second compartment), ensuring that the automatic pipette inside the compartment can adapt and complete precise pipetting operations. This design meets the requirement of automatic transfer of the placement stage 24 between the first and second compartments, realizing the function of the placement stage 24 as a reagent exchange carrier between the first and second compartments.
[0092] As some embodiments of this application, the drive mechanism 22 also includes a drive motor 222, a transmission belt 223, and a connector 224. The drive motor 222 may be constructed as a stepper motor, a linear motor, etc. The drive motor 222 has an output end, which is connected to the transmission belt 223 so that the drive motor 222 can drive the transmission belt 223 to rotate. The connector 224 and the transmission belt 223 may be fixedly connected by bolts, snap-fits, etc., and the connector 224 is fixedly connected to the drive rod 221. The drive motor 222 drives the transmission belt 223, thereby driving the connector 224 to move. The movement of the connector 224 can drive the drive rod 221, thereby driving the placement platform 24 to reciprocate relative to the guide rail 23 in the first direction. This is beneficial for the placement platform 24 to be smoothly moved into one of the first chamber, the second chamber, and the transfer chamber 1, and then the samples to be processed in the placement platform 24 are processed accordingly in sequence.
[0093] It should be noted that during the sample testing process, the placement stage 24 only needs to be transferred from the first compartment to the second compartment. Only after the testing operation is completed will the placement stage 24 return to the first compartment under the control of the testing program.
[0094] The delivery device 100 can be used for gene detection. The first and second chambers can be the extraction chamber and library construction chamber of a high-throughput sequencing (NGS) laboratory, respectively. The extraction chamber is equipped with extraction equipment for extracting the sample to be processed, and the library construction chamber is equipped with library construction equipment for converting the extracted sample into a standardized, identifiable library. Currently, to avoid cross-contamination of the samples, the extraction chamber and library construction chamber are located in different laboratory environments. By setting one end of the delivery mechanism 2 to extend into the extraction chamber and the other end to extend into the library construction chamber, and by using the delivery mechanism 2 to transport the sample from the extraction chamber to the library construction chamber via the delivery chamber 1, the process between the extraction and library construction steps is automated, improving detection efficiency, effectively preventing errors in detection results due to human error, improving the accuracy of detection results, and reducing the requirements for zoning in the high-throughput sequencing laboratory, saving construction costs for the high-throughput sequencing laboratory and reducing the time required for gene detection product deployment.
[0095] When the sample to be processed needs to be transferred from the extraction chamber to the construction chamber via transfer chamber 1, the air pressure in the extraction chamber is greater than that in the construction chamber. This application uses an example where the air pressure in the construction chamber is 5 Pa and the air pressure in the extraction chamber is 10 Pa. After the sample to be processed is placed in the extraction chamber, the extraction chamber and transfer chamber 1 are connected. It should be noted that at this time, the construction chamber and transfer chamber 1 are not connected. The air pressure in the extraction chamber and transfer chamber 1 will quickly exchange and reach equilibrium, eventually dropping to slightly below 10 Pa (at this time, the air pressure in the construction chamber is still about 5 Pa).
[0096] At the same time, the conveying mechanism 2 transports the sample to be processed in the extraction chamber to the transfer chamber 1. After the sample to be processed has completely entered the transfer chamber 1, the detection program controls the extraction chamber and the transfer chamber 1 to be disconnected, while the silo building chamber and the transfer chamber 1 are connected. Based on the same principle, the air pressure in the transfer chamber 1 and the silo building chamber will be rapidly exchanged and reach equilibrium, and eventually the overall pressure will rise to slightly higher than 5 Pa (at this time, the air pressure in the extraction chamber returns to about 10 Pa).
[0097] During this process, the air in transfer chamber 1 and the sample preparation chamber will not flow into the extraction chamber. After the conveying mechanism 2 continues to transport the sample to be processed from transfer chamber 1 to the sample preparation chamber, the sample preparation chamber and transfer chamber 1 are no longer connected. Throughout the entire process, the airflow always flows from the extraction chamber through transfer chamber 1 to the sample preparation chamber, ensuring a single flow direction. This effectively reduces the risk of cross-contamination between the gases in the extraction chamber and the sample preparation chamber, and improves the accuracy of the test results.
