Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of analysis equipment, in particular to a coagulation analyzer, a sample conveying device and a cup feeding method. BACKGROUND

[0002] When a full-automatic coagulation analyzer uses a magnetic bead method to detect a sample, a hollow transparent plastic cup with a rectangular belt positioning flange is generally used as a detection sample cup. The sample cup is composed of a positioning flange and a cup body, the cup body is used to hold a test liquid and a magnetic bead, and the positioning flange is used to support the sample cup. Since the bottom of the sample cup is a circular arc surface, if a braking condition suddenly occurs during the sample conveying process, the magnetic bead moves along the arc surface at a certain speed, and there is a risk of falling out of the cup opening, which limits the conveying speed of the sample cup to a certain extent. If the magnetic bead falls out of the sample cup, the detection method based on the magnetic bead is invalid, the detection result is reported as an error, and the accuracy and detection efficiency are affected. SUMMARY

[0003] Therefore, it is necessary to provide a coagulation analyzer, a sample conveying device and a cup feeding method in view of the risk that the magnetic bead in the current sample cup moves along the arc-shaped bottom and falls out of the cup opening.

[0004] The above-mentioned purpose is achieved by the following technical solutions:

[0015] The baffle extends along the transmission path of the transmission assembly. The baffle is located on a side of the feeding block facing the sample cup feeding mechanism and is used to limit the sample cup in the carrying cavity during transportation.

[0016] In one embodiment, when the sample cup is located in the carrying cavity, the magnetic member at least partially corresponds to the magnetic beads.

[0017] In one embodiment, when the sample cup is located in the carrying chamber, the magnetic member faces the magnetic beads.

[0018] In one embodiment, the magnetic member includes a permanent magnet or an electromagnet.

[0019] In one embodiment, the magnetic member is fixed to the feed block by gluing or screws.

[0020] In one embodiment, the sample cup conveying device further includes a sample cup storage mechanism, which is provided corresponding to the sample cup feeding mechanism and is used to store the sample cups. The sample cup feeding mechanism conveys the sample cups in the sample cup storage mechanism to the feeding block.

[0021] The sample cup storage mechanism includes a cup tray and a stripping assembly. The cup tray is used to store a sample cup strip consisting of a sample cup and a strip, and transport the sample cup strip to the sample cup feeding mechanism. The stripping assembly strips the strip from the sample cup at the sample cup feeding mechanism. The sample cup feeding mechanism carries the sample cup stripped from the sample cup strip, and pushes the sample cup into the carrying cavity of the feeding block at the loading position.

[0022] In one embodiment, the sample cup conveying device further includes a cup blocking mechanism;

[0023] When the feeding block leaves the loading position, the cup blocking mechanism moves to the loading position and blocks the outlet of the sample cup feeding mechanism supplying the sample cup;

[0024] When the feeding block returns to the loading position, the feeding block pushes the cup blocking mechanism to leave the loading position.

[0025] A cup conveying method for a sample cup conveying device, applied to the sample cup conveying device according to any of the above technical features, the cup conveying method comprising the following steps:

[0026] The feeding block moves to the loading position;

[0027] The sample cup feeding mechanism transports the sample cup containing the magnetic beads into the carrying cavity of the feeding block;

[0031] In one embodiment, the magnetic member is an electromagnet; and the magnetic member attracting the magnetic beads in the sample cup comprises the following steps:

[0032] When the sample cup feeding mechanism conveys the sample cup to the carrying cavity of the feeding block, power is supplied to the electromagnet, and the electromagnet attracts the magnetic beads of the sample cup in the carrying cavity;

[0036] The sample cup conveying device conveys the sample cup at the loading position to the unloading position, and the transfer device sequentially transfers the sample cup to the sample incubation device and the sample detection device.

[0037] After adopting the above technical solution, the present invention has at least the following technical effects:

[0038] The coagulation analyzer, sample conveying device, and cup feeding method of the present invention are such that when conveying a sample cup, the sample cup conveying mechanism drives the sample cup carrying mechanism to move to the loading position. The sample cup feeding mechanism loads the sample cup into the carrying cavity of the feed block of the sample cup carrying mechanism and secures it by adsorption via a magnetic element. The sample cup conveying mechanism then drives the feed block and the sample cup thereon to move to the unloading position. During the sample cup conveying process, the magnetic element can adsorb the magnetic beads in the sample cup within the carrying cavity, thereby fixing the position of the magnetic beads and limiting their displacement within the sample cup, thereby preventing them from moving along the curved bottom of the sample cup. This effectively addresses the risk of magnetic beads in the sample cup falling out of the cup mouth due to movement along the curved bottom, prevents magnetic beads from falling, avoids erroneous test results due to a lack of magnetic beads, and improves test accuracy. Furthermore, by using a magnetic element to restrict the movement of the magnetic beads, there is no need to reduce the conveying speed of the sample cup conveying mechanism, thereby improving test efficiency.

[0082] See also Figure 1 、 Figure 7 and Figure 8 The present invention provides a sample cup conveying device 100. The sample cup conveying device 100 is applied to a coagulation analyzer and is used to convey a sample cup 200. The sample cup conveying device 100 can convey the sample cup 200 to an unloading position and transfer the sample cup 200 through the transfer device 300 of the coagulation analyzer so that the coagulation analyzer can test the sample. Generally, the sample cup 200 used by the coagulation analyzer to test the sample includes a positioning flange and a cup body, the cup body is used to hold magnetic beads 210, and the positioning flange is used to support the sample cup 200. The sample cup conveying device 100 of the present invention can realize the reliable conveyance of the sample cup 200 and prevent the magnetic beads 210 in the sample cup 200 from falling out. At the same time, it can also increase the transportation speed of the sample cup 200 and improve the detection efficiency.

[0083] Referring to Figures 1 to 5 In an embodiment, the sample cup conveying device 100 comprises a sample cup feeding mechanism 110, a sample cup carrying mechanism 120 and a sample cup conveying mechanism 130. The sample cup feeding mechanism 110 is used to convey the sample cup 200. The sample cup carrying mechanism 120 is used to take the sample cup 200 from the sample cup feeding mechanism 110 and convey the sample cup 200 into the coagulation analyzer. The sample cup conveying mechanism 130 is the power source for the sample cup conveying, which can drive the sample cup carrying mechanism 120 to move so that the sample cup feeding mechanism 110 can convey an empty sample cup 200 to the loading position and return from the loading position to take a sample cup 200 from the sample storage mechanism.

[0084] Specifically, the sample cup feeding mechanism 110 is used to supply the sample cup 200 with magnetic beads 210 to the loading position. The sample cup carrying mechanism 120 comprises a feeding block 121 for carrying the sample cup 200 and a magnetic member 122 arranged on the feeding block 121. The feeding block 121 has a carrying cavity 1221 for receiving the sample cup 200 supplied by the sample cup feeding mechanism 110 at the loading position, and the magnetic member 122 is used to attract the magnetic beads 210 of the sample cup 200 in the carrying cavity 1221. The sample cup conveying mechanism 130 is connected with the sample cup carrying mechanism 120, and is used to move the sample cup carrying mechanism 120 between the loading position and the unloading position, so as to convey the sample cup 200 from the loading position to the unloading position.

[0085] Here, the loading position refers to the position where the sample cup feeding mechanism 110 sends the sample cup 200, such as the position where the feeding block 121 is located as shown in Figure 1 , and the unloading position refers to the position where the transfer device 300 accepts the sample cup 200 from the sample cup carrying mechanism 120, such as the position where the feeding block 121 is located as shown in Figure 5 . In this way, after the sample cup carrying mechanism 120 moves to the loading position, the sample cup feeding mechanism 110 conveys the sample cup 200 into the sample cup carrying mechanism 120, and then the sample cup conveying mechanism 130 drives the sample cup carrying mechanism 120 to move so that the sample cup carrying mechanism 120 moves from the loading position to the unloading position, and the transfer device 300 of the coagulation analyzer transfers the sample cup 200 in the sample cup carrying mechanism 120 at the unloading position. Then, the sample cup carrying device is empty and returns to the loading position, and the next sample cup 200 is conveyed.

[0086] Furthermore, the sample cup carrying mechanism 120 achieves reliable conveyance of the sample cup 200 through the cooperation of the feed block 121 and the magnetic member 122. Specifically, the sample cup conveying mechanism 130 can drive the feed block 121 to move between a loading position and an unloading position. The feed block 121 has a carrying cavity 1221 for carrying the sample cup 200. After the sample cup conveying mechanism 130 drives the feed block 121 to move to the loading position, the carrying cavity 1221 corresponds to the sample cup feeding mechanism 110, and the sample cup feeding mechanism 110 can feed the sample cup 200 into the carrying cavity 1221. It is understood that the sample cup feeding mechanism 110 can use a method such as cup grabbing or cup pushing to feed the sample cup 200 to the sample cup carrying mechanism 120, which will be described in detail later. After the sample cup conveyor mechanism 130 moves the feed block 121 loaded with sample cups 200 from the loading position to the unloading position, the loading chamber 1221 corresponds to the coagulation analyzer's transfer device 300. The transfer device 300 grabs the sample cup 200 from the feed block 121 and transfers it to the next workstation, such as the sample incubation device 400. Subsequently, the sample cup conveyor mechanism 130 drives the empty feed block 121 from the unloading position back to the loading position for the next process step.

[0087] It is understandable that, due to the curved bottom of the sample cup 200, the magnetic beads 210 may slide along the curved bottom of the sample cup 200 during transportation, and then fall out of the sample cup 200, which would affect the accurate detection of the sample. Based on this, the sample cup conveying device 100 of the present application adds a magnetic member 122 to the feed block 121. After the sample cup feeding mechanism 110 feeds the sample cup 200 into the carrying cavity 1221 of the feed block 121, the magnetic member 122 in the feed block 121 can attract the magnetic beads 210 in the sample cup 200, making it difficult for the magnetic beads 210 to move. In this way, during the transportation of the sample cup 200, the magnetic beads 210 in the sample cup 200 are always difficult to move and will not slide along the curved bottom of the sample, thereby preventing the magnetic beads 210 from falling out of the sample cup 200 and ensuring the accuracy of sample detection.

[0088] When the sample cup conveying device 100 transports a sample cup 200, the transmission assembly 131 drives the feed block 121 to the loading position. The sample cup feeding mechanism 110 then feeds the sample cup 200, containing the magnetic beads 210, into the loading chamber 1221 of the feed block 121. At this point, the magnetic member 122 attracts the magnetic beads 210 in the sample cup 200, preventing them from moving. Subsequently, the sample cup conveying mechanism 130, via the transmission assembly 131, drives the feed block 121 from the loading position to the unloading position. The transfer device 300 of the coagulation analyzer then transfers the sample cup 200 from the feed block 121. After the sample cup 200 is unloaded, the sample cup conveying mechanism 130, via the transmission assembly 131, drives the feed block 121 from the unloading position to the loading position to transport the next sample cup 200.

[0089] The sample cup conveying device 100 of the present invention adds a magnetic member 122 to the feed block 121 to attract the magnetic beads 210 in the sample cup 200 in the carrying cavity 1221, thereby limiting the movement of the magnetic beads 210 in the sample cup 200 and preventing the magnetic beads 210 from moving along the curved bottom of the sample cup 200. This effectively eliminates the risk of the magnetic beads 210 in the sample cup 200 falling out of the cup mouth when moving along the curved bottom, prevents the magnetic beads 210 from falling out, avoids false detection results due to the lack of magnetic beads 210, and improves detection accuracy. At the same time, by using the magnetic member 122 to limit the movement of the magnetic beads 210, the magnetic beads 210 can be prevented from falling out of the cup mouth while increasing the conveying speed of the sample cup conveying mechanism 130, thereby improving detection efficiency.

[0090] In one embodiment, when the sample cup 200 is within the holding cavity 1221, the magnetic induction intensity generated by the magnetic member 122 on the magnetic beads 210 in the sample cup 200 ranges from 40 to 50 millitesls. In other words, the magnetic induction intensity of the magnetic member 122 on the magnetic beads 210 ranges from 40 to 50 millitesls. This ensures that the attractive force exerted by the magnetic member 122 on the magnetic beads 210 is of reasonable magnitude, ensuring that the magnetic beads 210 are precisely attracted to the magnetic member 122 and cannot move, thus avoiding the problem of insufficient or excessive attractive force.

[0091] Understandably, if the attraction of the magnetic member 122 is insufficient, the magnetic member 122 may not be able to attract and fix the magnetic beads 210. When the sample movement mechanism drives the feed block 121 to move, the magnetic beads 210 in the sample cup 200 will slide along the curved bottom of the sample cup 200, and there is a risk that the magnetic beads 210 will fall out of the sample cup 200. If the attraction of the magnetic member 122 is too strong, the magnetic member 122 will attract the magnetic beads 210 in the sample cup 200 before the sample cup 200 enters the carrying cavity 1221 of the feed block 121. The magnetic beads 210 are attracted to the inner wall of the sample cup 200 on the side close to the feed block 121. Moreover, this attraction will pull one side of the sample cup 200 into the carrying cavity 1221 of the feed block 121 first, causing problems such as jamming and sample cup tilting, which affect the transportation of the sample cup 200.

[0092] Therefore, the present invention ensures the attraction of the magnetic member 122 to the magnetic beads 210 by limiting the magnetic induction intensity of the magnetic member 122, ensuring that the magnetic beads 210 are attracted by appropriate attraction, while also facilitating the loading of the sample cup 200 and avoiding the problem of jamming during the loading process of the sample cup 200.

[0093] In one embodiment, a distance is provided between the magnetic member 122 and the sample cup 200 in the carrying cavity 1221. This distance reduces the magnetic induction intensity generated by the magnetic member 122, thereby reducing the attraction force exerted by the magnetic member 122 on the magnetic beads 210 and preventing excessive magnetic force from being generated by the magnetic member 122. Furthermore, the distance is in the range of 4 mm to 5 mm. This ensures that the magnetic induction intensity generated by the magnetic member 122 is within a reasonable range, thereby ensuring a reasonable attraction force and preventing excessive attraction of the magnetic beads 210.

[0094] In one embodiment, the feed block 121 has an installation cavity, and the installation cavity is used to install the magnetic part 122. It can be understood that the magnetic part 122 can be completely installed in the installation cavity, and can also be partially installed in the installation cavity. Exemplarily, the magnetic part 122 is completely installed in the installation cavity. In this way, when the feed block 121 drives the magnetic part 122 to move, interference between the magnetic part 122 and other components can be avoided, thereby ensuring smooth operation. Of course, in other embodiments of the present invention, the magnetic part 122 can also be directly installed on the surface of the feed block 121, as long as it is ensured that the magnetic part 122 can attract the magnetic beads 210 in the carrying cavity 1221.

[0095] In one embodiment, the magnetic member 122 is secured to the feed block 121 by gluing or screws 123. This ensures that the magnetic member 122 is securely secured to the feed block 121, preventing the magnetic member 122 from falling during movement of the feed block 121 and ensuring that the magnetic beads 210 in the sample cup 200 are securely fixed. Of course, in other embodiments of the present invention, the magnetic member 122 may also be secured to the feed block 121 by means of clips or other methods. For example, the magnetic member 122 is secured to the feed block 121 by screws 123 to prevent the magnetic member 122 from falling.

[0096] Optionally, the shape of the magnetic member 122 is adapted to the shape of the installation cavity to facilitate the installation of the magnetic member 122. For example, the magnetic member 122 may be cylindrical, spherical, hexahedral, or the like.

[0097] In one embodiment, the mounting cavity and the carrying cavity 1221 are independently provided. That is, the mounting cavity and the carrying cavity 1221 are independent of each other and not connected. Thus, the portion of the feed block 121 between the mounting cavity and the carrying cavity 1221 blocks some magnetic lines of force, thereby reducing the magnetic induction intensity. This, in turn, maintains a reasonable magnetic induction intensity, ensuring that the magnetic member 122 accurately attracts the magnetic beads 210.

[0098] In an embodiment, the carrying cavity 1221 is located on the top of the feeding block 121 and is provided through to the side of the feeding block 121 facing the sample cup feeding mechanism 110 to receive the sample cup 200 fed from the sample cup feeding mechanism 110. The magnetic member 122 is located on the side of the carrying cavity 1221, or the magnetic member 122 is located on the bottom of the carrying cavity 1221. That is, the carrying cavity 1221 is a notch on the top of the feeding block 121, which is on the side of the sample cup feeding mechanism 110 to facilitate the feeding of the sample cup 200 by the sample cup feeding mechanism 110. The magnetic member 122 is located on the side wall of the carrying cavity 1221, or the magnetic member 122 is located on the bottom of the carrying cavity 1221. After the sample cup 200 is placed in the carrying cavity 1221, the magnetic member 122 can directly attract the magnetic beads 210 in the sample cup 200, and both can achieve the fixation of the magnetic beads 210 in the sample cup 200. Exemplarily, the magnetic member 122 is located on the side of the carrying cavity 1221 away from the sample cup feeding mechanism 110.

[0099] It can be understood that the shape of the carrying cavity 1221 is matched with the shape of the sample cup 200, and when the sample cup 200 is placed in the carrying cavity 1221, there is a proper gap to ensure that the sample cup 200 can be reliably placed in the carrying cavity 1221, and also facilitate the loading and unloading of the sample cup 200.

[0100] In an embodiment, the sample cup conveying mechanism 130 includes a transmission assembly 131 and a blocking plate 132. The transmission assembly 131 is connected with the feeding block 121 to drive the feeding block 121 to move. The transmission assembly 131 can drive the feeding block 121 to move between the loading position and the unloading position. After the feeding block 121 carries the sample cup 200 fed by the sample cup feeding mechanism 110, the transmission assembly 131 drives the feeding block 121 to move from the loading position to the unloading position, and then the sample cup 200 in the feeding block 121 is grabbed by the transfer device 300 of the coagulation analyzer and transferred. Then, the transmission assembly 131 drives the feeding block 121 to move from the unloading position to the loading position for the loading and conveying of the next sample cup 200.

[0101] The blocking plate 132 extends along the transmission path of the transmission assembly 131. The blocking plate is located on the side of the feed block 121 facing the sample cup feeding mechanism 110 and is used to limit the position of the sample cup 200 within the carrying chamber 1221 during transportation. The blocking plate 132 serves to limit the sample cup 200 within the carrying chamber 1221. Because the carrying chamber 1221 has a notched structure, the sample cup 200 may fall out of the carrying chamber 1221 during the feeding block 121. After the blocking plate 132 is installed, the blocking plate 132 is located at the notch of the carrying chamber 1221 and, together with the other three side walls of the carrying chamber 1221, forms a limiting chamber, which ensures that the sample cup 200 is securely positioned within the carrying chamber 1221, preventing the sample cup 200 from escaping the carrying chamber 1221 and ensuring reliable transportation of the sample cup 200.

[0102] At the same time, due to the attraction of magnetic member 122, magnetic member 122 attracts magnetic beads 210 to the inner wall of sample cup 200, allowing magnetic beads 210 to pull sample cup 200 as close to magnetic member 122 as possible. In other words, after magnetic member 122 attracts magnetic beads 210, it causes the outer wall of sample cup 200, sandwiched between the two, to cling tightly to the inner wall of carrying cavity 1221, thereby positioning sample cup 200. This maintains a gap between blocking plate 132 and sample cup 200, preventing friction between the sample cup 200 and blocking plate 132 and the generation of debris. This ensures reliable transport of sample cup 200, improves detection accuracy, and reduces maintenance costs.

[0103] Optionally, the transmission assembly 131 includes but is not limited to a gear rack transmission assembly, a chain sprocket transmission assembly, a synchronous belt transmission assembly or a ball screw assembly, and can also be other structures that can realize the movement drive of the feed block 121.

[0104] Furthermore, the sample cup conveying mechanism 130 further includes a guide assembly 133, which is used to guide the movement of the feed block 121, allowing the feed block 121 to move along a fixed path, thereby ensuring smooth and reliable movement of the feed block 121. Optionally, the guide assembly 133 includes, but is not limited to, a slide rail and slider assembly, a slide rail and slot assembly, etc., and may also be other structures capable of providing guidance.

[0105] In one embodiment, when the sample cup 200 is located in the holding cavity 1221, the magnetic member 122 at least partially corresponds to the magnetic beads 210 (typically located at the bottom of the cup). That is, the magnetic member 122 can be positioned partially offset from the magnetic beads 210, or it can be positioned directly opposite the magnetic beads 210. This facilitates the magnetic member 122 to attract the magnetic beads 210. For example, when the sample cup 200 is located in the holding cavity 1221, the magnetic member 122 directly corresponds to the magnetic beads 210 at the bottom of the cup.

[0106] In one embodiment, the magnetic member 122 includes a permanent magnet or an electromagnet.

[0107] Optionally, the magnetic member 122 comprises a permanent magnet, and the sample cup 200 is located behind the bearing cavity 1221, and the magnetic beads 210 in the sample cup 200 are located in the magnetic field of the permanent magnet to attract the magnetic beads 210. It can be understood that the magnetic induction intensity generated by the magnetic member 122 covers the bearing cavity 1221. That is, before the sample cup 200 enters the bearing cavity 1221, the magnetic member 122 has a small magnetic attraction to the magnetic beads 210 in the sample cup 200 in the sample cup feeding mechanism 110, and it is difficult to effectively attract the magnetic beads 210 to limit the movement of the magnetic beads 210. After the sample cup 200 enters the bearing cavity 1221, the magnetic member 122 attracts the magnetic beads 210 to limit the movement of the magnetic beads 210. In this way, it can be avoided that the sample cup 200 is tilted during the feeding process of the sample cup feeding mechanism 110, and the sample cup 200 can be smoothly fed into the bearing cavity 1221. Moreover, the magnetic member 122 generates a small attractive force, which can only attract the magnetic beads 210, and will not generate a large attractive force.

[0108] Optionally, the permanent magnet is made of ferritic boron material, and the shape thereof is not limited in principle, as long as the magnetic member 122 can generate a suitable attractive force at the corresponding position, so as to avoid being too large or too small.

[0109] Exemplarily, the magnetic member 122 comprises a permanent magnet, and the permanent magnet is made of ferritic boron. The permanent magnet is in a columnar shape, and the size thereof is 10 mm in diameter and 5 mm in height. The thickness of the sample cup 200 is 4.75 mm, the wall thickness is 0.55 mm, the weight is 0.28 g, and the diameter of the magnetic beads 210 is 2.3 mm. The center of the circular end face of the magnetic member 122 is aligned with the position where the magnetic beads 210 are naturally placed at the bottom of the sample cup 200, and the thickness of the feeding block 121 therebetween is 4.9 mm. Under the above conditions, the design requirements of the present application can be met, which can not only ensure that the jumping of the magnetic beads 210 is limited and the magnetic beads 210 will not be bounced out of the sample cup 200 during the movement, but also can play a positioning role for the sample cup 200, and there is no other risk of failure.

[0110] In another embodiment of the present invention, the magnetic member 122 comprises an electromagnet. After the sample cup 200 is positioned in the loading chamber 1221, the electromagnet is energized to attract the magnetic beads 210. That is, while the sample cup feeding mechanism 110 is feeding the sample cup 200 into the loading chamber 1221 of the feed block 121, the electromagnet is not energized and does not attract the magnetic beads 210. Once the sample cup 200 is positioned in the loading chamber 1221, the electromagnet is energized to attract the magnetic beads 210, preventing them from moving. At this point, the transmission assembly 131 can drive the feed block 121 from the loading position to the unloading position. The electromagnet is then de-energized, removing the attraction to the magnetic beads 210, and the transfer device 300 transfers the sample cup 200 from the feed block 121. After the transfer is complete, the transmission assembly 131 drives the sample cup 200 back from the unloading position to the loading position. It will be appreciated that the electromagnet is de-energized during the loading and unloading of the sample cup 200, as well as the return of the feed block 121 to the loading position. This can ensure that the magnetic beads 210 do not pop out during the transportation of the sample cup 200, and can also avoid the interference of the attraction of the electromagnet on the loading and unloading process, thereby facilitating the loading and unloading of the sample cup 200.

[0111] See also Figure 1 and Figure 6 In one embodiment, the sample cup conveying device 100 further includes a sample cup storage mechanism 140. The sample cup storage mechanism 140 is provided in correspondence with the sample cup feeding mechanism 110 and is used to store sample cups 200. The sample cup feeding mechanism 110 transports the sample cups 200 from the sample cup storage mechanism 140 to the feed block 121. The sample cup storage mechanism 140 is used to store sample cups 200 used by the coagulation analyzer for sample testing. It will be appreciated that the sample cup storage mechanism 140 can store a large number of sample cups 200 to enable continuous transport of sample cups 200, ensuring continuous sample testing by the coagulation analyzer. When the coagulation analyzer is operating, the sample cup storage mechanism 140 transports the sample cups 200 to the sample cup feeding mechanism 110, which then feeds the sample cups 200 into the carrying cavity 1221 of the feed block 121.

[0112] Optionally, the sample cup storage mechanism 140 includes a cup tray 141 and a stripping assembly 142. The cup tray 141 is used to store a sample cup strip consisting of a sample cup 200 and a strip 220, and transport the sample cup strip to the sample cup feeding mechanism 110. The stripping assembly 142 pulls the sample cup strip and strips the strip 220 from the sample cup 200 at the sample cup feeding mechanism 110. The sample cup feeding mechanism 110 carries the sample cups 200 stripped from the sample cup strip, and by pulling the sample cup strip, the sample cups 200 that have not yet been stripped push the stripped sample cups 200 to move on the sample cup feeding mechanism 110, and pushes the first sample cup 200 that arrives at the loading position in the sample cup queue into the carrying cavity 1221 of the feeding block 121 at the loading position.

[0113] Generally, the sample cup strip includes the sample cups 200 and the strip 220, the top of the sample cup 200 is clamped on the strip 220, and a plurality of sample cups 200 are arranged in an orderly and close manner, and the sample cup strip is arranged in a roll form. In this way, the sample cup 200 can be conveniently stored and transported, and the magnetic beads 210 in the sample cup 200 can also be prevented from falling off. The sample cup strip in the roll form is installed on the cup disc 141. When the cup disc 141 rotates, the sample cup strip is transported to the sample cup feeding mechanism 110. One end of the strip 220 is connected to the strip stripping assembly 142, and the strip stripping assembly 142 pulls the strip 220, so that the sample cup 200 is separated from the strip 220 in the process of feeding the sample cup 200 by the sample cup feeding mechanism 110, and then the sample cup feeding mechanism 110 can feed the sample cup 200 to the feeding block 121.

[0114] It can be understood that, in the embodiment, the strip stripping assembly 142 includes the lifting piece 1421, the strip pressing wheel 1423 and the winding wheel 1422. The lifting piece 1421 extends into the gap between the strip 220 and the sample cup 200, and helps the sample cup 200 to be stripped from the sample cup strip when the sample cup strip is pulled, and lifts the strip 220 on the sample cup strip. The winding wheel 1422 is used to be connected with the strip 220 and wind the strip 220. The strip pressing wheel 1423 is arranged on the sample cup strip of the sample cup feeding mechanism 110, so that the sample cup 200 can be pressed on the sample cup feeding mechanism 110.

[0115] It can be understood that, since the diameter of the cup disc 141 is large, there is a certain height difference between the loading position and the unloading position. Therefore, in the embodiment, the transmission assembly 131 obliquely upwardly transports the feeding block 121. In this way, the transmission assembly 131 can drive the feeding block 121 to load the sample cup 200 at the lower loading position and transport the sample cup 200 to the higher unloading position.

[0116] Of course, in other embodiments of the present application, the sample storage mechanism 140 can also be a storage chamber, and the sample cups 200 are arranged in rows and columns in the storage chamber. The sample cup 200 is transferred to the sample cup feeding mechanism 110 by the cup grabbing hand, and then the sample cup feeding mechanism 110 feeds the sample cup 200 to the feeding block 121.

[0117] Optionally, the sample cup feeding mechanism 110 can be a straight pushing structure for transporting the sample cup 200 along a straight line. The straight pushing structure has a conveying groove in which the sample cups 200 are arranged in a row. That is, the head of the sample cup feeding mechanism 110 feeds the sample cup 200 to the feeding block 121, and the tail of the sample cup feeding mechanism 110 obtains the sample cup 200 from the cup disc 141. When the strip stripping assembly 142 pulls the sample cup strip, the sample cup 200 at the head of the sample cup queue is pushed into the carrying cavity 1221 of the feeding block 121. Of course, in other embodiments of the present application, the sample cup feeding mechanism 110 can be a cup grabbing hand, which grabs the sample cup 200 into the carrying cavity 1221 of the feeding block 121.

[0118] In an embodiment, the sample cup conveying device 100 further comprises a cup blocking mechanism 150. The cup blocking mechanism 150 functions to block the sample cup 200 from falling out of the outlet of the sample cup feeding mechanism 110. It can be understood that if there is no cup blocking mechanism 150, the sample cup 200 at the outlet of the sample cup feeding mechanism 110 will fall out under the pushing force when the feeding block 121 is driven by the transmission assembly 131 to move away from the loading position. Therefore, the cup blocking mechanism 150 can be added to the head of the sample cup feeding mechanism 110 to prevent the sample cup 200 from falling out.

[0119] Specifically, when the feeding block 121 moves away from the loading position, the cup blocking mechanism 150 moves to the loading position and blocks the outlet of the sample cup feeding mechanism 110 to prevent the sample cup 200 from falling out. When the feeding block 121 returns to the loading position, the feeding block 121 pushes the cup blocking mechanism 150 away from the loading position. That is, the cup blocking mechanism 150 is movably arranged at the loading position of the outlet of the sample cup feeding mechanism 110. When the feeding block 121 moves away from the loading position, the cup blocking mechanism 150 moves to the loading position and blocks the outlet of the sample cup feeding mechanism 110. When the feeding block 121 returns to the loading position, the feeding block 121 pushes the cup blocking mechanism 150 away from the loading position.

[0120] It can be understood that when the feeding block 121 is at the loading position, the cup blocking mechanism 150 is located at one side of the feeding block 121. In this way, interference between the cup blocking mechanism 150 and the feeding block 121 can be avoided, and the feeding block 121 can be ensured to move smoothly. The cup blocking mechanism 150 comprises a cup blocking block and an elastic member connecting the cup blocking block and the sample cup feeding mechanism 110. When the feeding block 121 returns to the loading position, the feeding block 121 pushes the cup blocking block away from the loading position, and the elastic member is deformed. When the feeding block 121 moves away from the loading position, the elastic member returns to the state before deformation, and the cup blocking block is reset under the action of the elastic member to block the outlet of the sample cup feeding mechanism 110. In the embodiment, the elastic member is a spring. When the feeding block 121 pushes the cup blocking block away from the loading position, the spring is compressed. When the feeding block 121 moves away from the loading position, the spring returns to the non-compressed state.

[0121] The present application further provides a cup feeding method of a sample cup conveying device 100, which can be applied to the sample cup conveying device 100 in any of the above embodiments. The cup feeding method comprises the following steps:

[0122] The feeding block 121 moves to the loading position;

[0123] The sample cup feeding mechanism 110 conveys the sample cup 200 with the magnetic beads 210 placed therein to the bearing cavity 1221 of the feeding block 121;

[0124] The magnetic member 122 attracts the magnetic beads 210 of the sample cup 200;

[0125] The sample cup conveying mechanism 130 controls the feeding block 121 to move from the loading position to the unloading position;

[0126] After the sample cups 200 in the feeding block 121 are unloaded, the sample cup conveying mechanism 130 controls the feeding block 121 to move from the unloading position to the loading position.

[0127] When the sample cup conveying device 100 transports a sample cup 200, the transmission assembly 131 drives the feed block 121 to the loading position. The sample cup feeding mechanism 110 then feeds the sample cup 200, containing the magnetic beads 210, into the loading chamber 1221 of the feed block 121. At this point, the magnetic member 122 attracts the magnetic beads 210 in the sample cup 200, preventing them from moving. Subsequently, the sample cup conveying mechanism 130, via the transmission assembly 131, drives the feed block 121 from the loading position to the unloading position. The transfer device 300 of the coagulation analyzer then transfers the sample cup 200 from the feed block 121. After the sample cup 200 is unloaded, the sample cup conveying mechanism 130, via the transmission assembly 131, drives the feed block 121 from the unloading position to the loading position to transport the next sample cup 200.

[0128] In one embodiment, the magnetic member 122 is an electromagnet. The process of attracting the magnetic beads 210 in the sample cup 200 by the magnetic member 122 includes the following steps: after the sample cup feeding mechanism 110 transports the sample cup 200 to the loading cavity 1221 of the feed block 121, the electromagnet is powered, causing the electromagnet to attract the magnetic beads 210 in the sample cup 200 in the loading cavity 1221. In this embodiment, the cup feeding method further includes the step of de-energizing the electromagnet after the sample cup transport mechanism 130 controls the feed block 121 to move from the loading position to the unloading position.

[0129] During the process of feeding the sample cup 200 into the loading cavity 1221 of the feed block 121, the electromagnet is in a de-energized state and does not generate attraction. Once the sample cup 200 is in the loading cavity 1221, the electromagnet is energized to attract the magnetic beads 210, securing the position of the beads 210 and positioning the sample cup 200. At this point, the transmission assembly 131 can drive the feed block 121 from the loading position to the unloading position. The electromagnet is then de-energized, removing the attraction of the magnetic beads 210, and the transfer device 300 can transfer the sample cup 200 from the feed block 121. After the transfer of the sample cup 200 is complete, the transmission assembly 131 drives the sample cup 200 back from the unloading position to the loading position. It will be appreciated that in some embodiments, the electromagnet is de-energized during the loading and unloading of the sample cup 200 and the return of the feed block 121 to the loading position. This can ensure that the magnetic beads 210 do not pop out during the transportation of the sample cup 200, and can also avoid the interference of the suction force of the electromagnet on the loading and unloading process, thereby facilitating the loading and unloading of the sample cup 200.

[0130] See also Figure 1 、Figure 7 and Figure 8 The present invention further provides a coagulation analyzer, comprising a sample incubation device 400 for incubating samples, a transfer device 300 for transferring sample cups 200, a sample detection device 500 for detecting samples, and a sample cup transport device 100 for transporting sample cups 200, as in any of the above embodiments.

The sample cup transport device 100 is located on the side of the test platform 620. The placement chamber 610 is used to install the coagulation analyzer's circuitry and wiring, controller, and power supply.

[0132] The sample transport device 700 is used to transport the sample to be tested, so as to realize the automatic transport of the sample to be tested, thereby improving the sampling efficiency and thus improving the working efficiency of the coagulation analyzer. The sample cup transport device 100 is used to transport the sample cup 200, so as to realize the automatic transport of the empty sample cup 200 and improve the transport efficiency. The dispensing device 800 is used to aspirate and discharge the sample or reagent, so as to realize the addition of the sample or reagent to the corresponding sample cup 200. The sample incubation device 400 is used to incubate the sample so that the sample reaches the optimal reaction conditions and facilitates the detection of the sample parameters. The reagent storage device 900 is used to store reagents and can store various reagents required for sample testing, making it convenient to select the required reagents and improving the efficiency of reagent aspiration. The transfer device 300 is used to transfer the sample cup 200 so that the sample cup 200 can be moved to various required positions of the coagulation analyzer, realizing automatic analysis and detection of the sample and improving operating efficiency. The sample detection device 500 is used to detect the sample to obtain the corresponding parameters of the sample.

[0133] Specifically, the sample incubation device 400 and the reagent storage device 900 are arranged side by side, the sample transport device 700 is located on one side of the sample incubation device 400 and the reagent storage device 900, and the sample cup transport device 100, the transfer device 300, and the sample testing device 500 are located on the other side of the sample incubation device 400 and the reagent storage device 900.

The transfer device 300 can move between the sample cup transport device 100, the sample incubation device 400, and the sample testing device 500. The transfer device 300 can transfer the sample cup 200 transported by the sample cup transport device 100 to the sample incubation device 400, and the transfer device 300 can transfer the sample cup 200 in the sample incubation device 400 to the sample testing device 500. The dispensing device 800 is located in the area between the sample incubation device 400 and the reagent storage device 900 to transfer the sample and the reagent into the sample cup 200 of the sample incubation device 400 respectively.
