[0056] The emergency component 5500 includes a flip seat 5510, which can be flipped and braked. The flip seat 5510 is provided with a first hole for placing the emergency cup, and the first hole is not shown in the drawings.

[0057] The sample rack automatic entry and exit device of the present application is installed at the corresponding position of the immunoassay analyzer such as the flow fluorescence and chemiluminescence analyzer. The sample inlet area 5001 of the support assembly 5100 is sequentially placed with a plurality of sample racks 5600 along the sample inlet direction. A sample cup with a sample to be tested is placed on each sample rack 5600. The sample inlet mechanism 5200 pushes the sample racks 5600 in the sample inlet area 5001 to the position corresponding to the transverse movement area 5003 in sequence. Then, the transverse movement mechanism 5300 pushes a sample rack 5600 corresponding to the transverse movement area 5003 in the sample inlet area 5001 along the transverse movement area 5003 to the sample outlet area 5002. The transverse movement area 5003 corresponds to a sample suction station.

[0058] Therefore, the automatic sample rack entry and exit device of the present application has a simple structure, small size, and is easy and quick to operate. The flip seat 5510 can be flipped to facilitate the rotation of the emergency cup to the replacement position and the liquid collection position. Emergency testing can be performed immediately during the sampling process of the sample rack 5600, which is highly efficient and reduces costs, etc., and is easier to be used in immunoassay analyzers such as flow fluorescence and chemiluminescence.

The lower end of the first connecting plate 5530 is integrally formed with a second hole body 5531 by bending and other processing, and an opening is provided on the second hole body 5531 along its axial direction. When the flip seat 5510 flips toward the direction of the lateral movement area 5003 to the position corresponding to the emergency cup and the sample suction station, the bottom of the flip seat 5510 can also be pressed against the top plate for limiting. As a result, the structure is simpler and more stable, and the processing and manufacturing are more convenient.

[0064] In some embodiments, a first detection switch for detecting the emergency cup is provided in the first hole. The first detection switch is not shown in the drawings, and the first detection switch can be a travel switch, a photoelectric switch, a proximity switch, etc. Thus, the emergency cup in the first hole is detected by the first detection switch to determine whether the emergency cup is properly placed on the flip seat 5510, which is safer and more reliable.

[0065] In some embodiments, a second detection switch 5540 for detecting the flip position of the flip seat 5510 is provided on the first bracket 5520. The second detection switch 5540 can be a photoelectric switch, a proximity switch, etc., such as a slot-type optical coupling sensor. Thus, by detecting whether the flip seat 5510 is flipped in place through the second detection switch 5540, the operation is more convenient, the accuracy of the equipment is improved, and the safety and reliability are higher.

[0066] In some embodiments, a flip limiter 5511 is further provided at the lower end of the flip seat 5510. The flip limiter 5511 may be a protrusion similar to a triangle or other suitable shapes. When the flip seat 5510 flips in a direction away from the lateral movement area 5003 to a position where the emergency cup can be placed for replacement, the flip limiter 5511 may be pressed against the first bracket 5520 for limiting, thereby making the operation more convenient, improving the accuracy of the device, and increasing safety and reliability.

[0067] In some embodiments, a handle portion 5512 is provided on the top of the flip seat 5510. Thus, the flip seat 5510 can be flipped by the handle portion 5512, which makes the operation more convenient.

[0068] In some embodiments, the emergency component 5500 further includes a shell, on which a avoidance zone corresponding to the flip seat 5510 is provided, and other components of the emergency component 5500 are located in the shell, which is connected to the first bracket 5520. The shell is not shown in the drawings, and the shell and the first bracket 5520 can be connected by snap-fit ​​or screws, etc. The first bracket 5520 is provided with a snap-fit ​​structure connected to the shell, etc. Thus, safety and reliability are higher.

[0069] In some embodiments, the support assembly 5100 includes: a base 5110. A carrying plate 5120 is disposed at the upper end of the base 5110, and the sample inlet area 5001, the sample outlet area 5002 and the lateral movement area 5003 are distributed on the carrying plate 5120. The carrying plate 5120 is provided with a sample inlet channel 5121 located in the sample inlet area 5001, a lateral movement channel 5122 located in the lateral movement area 5003 and a sample outlet channel 5123 located in the sample outlet area 5002. The lateral movement channel 5122 is located at one end between the sample inlet channel 5121 and the sample outlet channel 5123 and is connected to the sample inlet channel 5121 and the sample outlet channel 5123 respectively. The carrying plate 5120 is provided with a first avoidance through hole 5124 corresponding to the emergency component 5500.

[0070] That is, the sample racks 5600 in the sample injection area 5001 are sequentially placed along the sample injection channel 5121, the sample injection mechanism 5200 pushes the sample racks 5600 to positions corresponding to the transverse channel 5122 along the sample injection channel 5121, the transverse mechanism 5300 pushes the sample racks 5600 corresponding to the transverse channel 5122 in the sample injection channel 5121 along the transverse channel 5122 toward the direction of the sample outlet channel 5123, and the sample outlet mechanism 5400 pushes the sample racks 5600 in the sample outlet channel 5123 along the sample outlet channel 5123 toward the end away from the transverse channel 5122. Thus, the structure is simpler, more compact, smaller in size, safer and more reliable.

[0071] Furthermore, baffles 5130 are respectively arranged around the supporting plate 5120. Thus, the baffles 5130 can limit the position of the sample rack 5600, which is safer and more reliable.

[0072] In some embodiments, a control component 5700 is also disposed on the base 5110. The control component 5700 generally includes electrical components such as a control circuit board and a control switch, which are not described in detail here. Thus, the operation is more convenient.

[0073] In some embodiments, the injection mechanism 5200 includes a first driving member 5220 and two first push blocks 5210. The first driving member 5220 is connected to the two first push blocks 5210, the two first push blocks 5210 are respectively located on both sides above the injection channel 5121 and are symmetrically arranged, the first driving member 5220 is arranged on the base 5110 and is located below the carrier plate 5120, the first driving member 5220 drives the two first push blocks 5210 to move reciprocatingly in the direction of the injection channel 5121, and the two first push blocks 5210 push the sample rack 5600 to move linearly along the injection channel 5121 toward one end of the traverse channel 5122.

[0074] That is, the first driving member 5220 drives the two first push blocks 5210 to move synchronously, so that the two first push blocks 5210 push the sample rack 5600 to move linearly along the injection channel 5121 toward one end of the transverse channel 5122. Thus, the structure is simpler, more compact, smaller in size, more stable and reliable.

[0075] In some embodiments, the two first push blocks 5210 are respectively disposed at both ends of the second connecting plate 5230, the first driving member 5220 is connected to the second connecting plate 5230, and the second connecting plate 5230 is located below the carrier plate 5120. Thus, the first driving member 5220 drives the second connecting plate 5230 to move, and the second connecting plate 5230 drives the two first push blocks 5210 to move synchronously, thereby ensuring that the two first push blocks 5210 better push the sample rack 5600 to inject samples, which is more stable and reliable.

[0076] In some embodiments, the second connecting plate 5230 is provided with a limiting column 5240 and an elastic member 5250 respectively matched with each first push block 5210, and the two first push blocks 5210 are respectively hinged to the second connecting plate 5230 through a second rotating shaft 5260, and each second rotating shaft 5260 is arranged in the vertical direction. As the two first push blocks 5210 push the sample rack 5600 for sample injection, the first push blocks 5210 abut against the limiting column 5240 for limiting; as the first driving member 5220 drives the two first push blocks 5210 to move in the opposite direction of the injection direction for reset, when the two first push blocks 5210 hit the sample rack 5600, the two first push blocks 5210 can respectively rotate toward the outside of the injection channel 5121 and the elastic member 5250 elastically deforms, so that the two first push blocks 5210 pass through the two sides of the sample rack 5600 respectively.

[0077] That is to say, when the two first push blocks 5210 push the sample rack 5600 for sample injection, the first push blocks 5210 are limited against the limiting column 5240 to ensure that the sample rack 5600 is pushed stably for sample injection. When the first driving member 5220 drives the two first push blocks 5210 to reset in the opposite direction of the injection direction, if the two first push blocks 5210 hit the sample rack 5600, the two first push blocks 5210 can be rotated toward the outside of the injection channel 5121 respectively and the elastic member 5250 is elastically deformed, so that the two first push blocks 5210 pass through the two sides of the sample rack 5600 respectively. The elastic member 5250 can also automatically reset the first push blocks 5210, so that the operation is more convenient and the safety, stability and reliability are higher.

[0078] Furthermore, the elastic member 5250 can be a tension spring, the hook at one end of the tension spring is connected to the corresponding first push block 5210, the hook at the other end of the tension spring is connected to the second connecting plate 5230, and the first pushing block 5210 and the second connecting plate 5230 are respectively provided with a hole or hook groove connected to the hook of the tension spring. Thus, the structure is simpler and the operation is more convenient.

[0079] In some embodiments, a guide mechanism matched with the second connecting plate 5230 is provided on the base 5110, and the guide mechanism can be a linear slide rail provided along the injection direction, etc. The first driving member 5220 can also be connected to the second connecting plate 5230 through a transmission mechanism, and the transmission mechanism can be a synchronous belt mechanism, a gear mechanism, a chain transmission mechanism, etc. The first driving member 5220 can be a stepping motor, a servo motor, etc. Thus, the first driving member 5220 drives the second connecting plate 5230 to reciprocate linearly along the guide mechanism through the transmission mechanism, which is more accurate, stable and reliable.

[0080] In some embodiments, the transverse mechanism 5300 includes: a transverse plate 5310 and a second driving member 5320. The second driving member 5320 is disposed on the base 5110 and is located below the bearing plate 5120. The transverse plate 5310 is connected to the second driving member 5320, and the second driving member 5320 drives the transverse plate 5310 to reciprocate linearly along the direction of the transverse channel 5122. The transverse plate 5310 is provided with a second push block 5312 and a first limit portion 5311 matched with the second push block 5312. The second push block 5312 is hinged to the transverse plate 5310 through a third rotating shaft 5313. The third rotating shaft 5313 is arranged in the horizontal direction and the transverse channel 5122 is vertical. The supporting plate 5120 is provided with a second avoidance through hole corresponding to the second push block 5312. The upper end of the second push block 5312 can pass through the second avoidance through hole and be inserted into the third hole body at the bottom of the sample rack 5600. The third hole body corresponds one-to-one to the sample cup placed on the sample rack 5600. The second avoidance through hole and the third hole body are not shown in the accompanying drawings. As the second pushing block 5312 pushes the sample rack 5600 to move toward the sample output area 5002, the first limiting portion 5311 limits the second pushing block 5312; as the second driving member 5320 drives the second pushing block 5312 to move toward the sample input area 5001, the second pushing block 5312 can move from one third hole body to another adjacent third hole body by rotating.

[0081] That is to say, the length of the second avoidance through hole is generally substantially consistent with the spacing between the two third holes, and the second avoidance through hole can also limit the moving distance of the second push block 5312. When the second push block 5312 pushes the sample rack 5600 to move toward the sample output area 5002, the first limiter 5311 limits the second push block 5312 at the same time, ensuring that the sample rack 5600 is pushed more stably to move the distance of one sample cup each time, that is, each time the second push block 5312 pushes the sample rack 5600 to move once, a sample cup on the sample rack 5600 moves to a position corresponding to the sample suction station; when the second driving member 5320 drives the second push block 5312 to move toward the sample input area 5001, the second push block 5312 moves from one third hole to another adjacent third hole by rotating, so that the sample rack 5600 moves the distance of one sample cup each time, thereby ensuring that the sample cups on the sample rack 5600 move to the sample suction station in sequence. As a result, the accuracy is higher, and it is more stable and reliable.

[0082] In some embodiments, the third rotating shaft 5313 is located at the upper end of the second push block 5312 close to the sample inlet area 5001, and the first limiting portion 5311 is located at the lower end of the second push block 5312 close to the sample outlet area 5002. Under the gravity of the second push block 5312, the lower end of the second push block 5312 abuts against the first limiting portion 5311 and the second push block 5312 tilts toward the sample outlet area 5002. The second push block 5312 may be one, two, or more.

[0083] That is, in the non-working state, the second push block 5312 relies on its own weight so that the lower end of the second push block 5312 abuts against the first limit portion 5311 and the second push block 5312 tilts toward the sample outlet area 5002; when the second driving member 5320 drives the second push block 5312 to move toward the sample inlet area 5001, the upper end of the second push block 5312 rotates downward, and when the second push block 5312 moves from one third hole body to another adjacent third hole body, the second push block 5312 relies on its own weight so that the upper end of the second push block 5312 rotates upward to reset. As a result, the structure is simpler and the installation and other operations are convenient.

[0084] Those skilled in the art will appreciate that the lower end of the second push block 5312 may be elastically pressed against the first limit portion 5311 by means of elastic elements such as tension springs and torsion springs, and the elastic elements may also facilitate pushing the second push block 5312 to reset.

[0085] In some embodiments, the second push block 5312 is respectively disposed at one end of the transverse moving plate 5310 close to the sample inlet area 5001 and one end close to the sample outlet area 5002. In other words, the second push blocks 5312 are respectively disposed at both ends of the transverse moving plate 5310, so as to better push the sample rack 5600 from the sample inlet area 5001 to the transverse moving area 5003 and the sample outlet area 5002 in sequence, and also reduce the moving distance of the transverse moving plate 5310.

[0086] In some embodiments, the second driving member 5320 is disposed on the second bracket 5330, and the second bracket 5330 is mounted on the base 5110. A pressure rod assembly 5340 is disposed on the second bracket 5330, and the pressure rod assembly 5340 is used to press the sample rack 5600 in the transverse channel 5122 during the sample aspiration process. The pressure rod assembly 5340 can be one, two, or more. Thus, the sample rack 5600 is more stable during the sample aspiration process.

[0087] In some embodiments, the pressure bar assembly 5340 includes a swing block 5341 and a pressure bar 5346. The swing block 5341 is hinged to the second bracket 5330 through a fourth rotating shaft 5345, and the fourth rotating shaft 5345 is parallel to the third rotating shaft 5313. The transverse plate 5310 is provided with a third push block 5314 corresponding to the swing block 5341, and the pressure bar 5346 is provided on the swing block 5341. The pressure bar 5346 is located above the side of the transverse channel 5122 away from the emergency component 5500. As the second push block 5312 pushes the sample rack 5600 to move toward the sample output area 5002, the third push block 5314 pushes the swing block 5341 to rotate so that the pressure bar 5346 presses against the sample rack 5600; as the transverse plate 5310 moves toward the sample input area 5001, the swing block 5341 can rotate in the opposite direction so that the pressure bar 5346 releases the sample rack 5600.

[0088] That is, when the second push block 5312 pushes the sample rack 5600 to move toward the sample output area 5002, the third push block 5314 pushes the swing block 5341 to rotate, so that the pressure rod 5346 swings downward to press the sample rack 5600; when the corresponding sample cup on the sample rack 5600 is located at the sample suction station, the pressure rod 5346 presses the sample rack 5600 tightly to ensure that the sample rack 5600 does not slide during the sampling process; when the transverse plate 5310 moves toward the sample input area 5001, the swing block 5341 rotates in the opposite direction, so that the pressure rod 5346 is lifted upward to release the sample rack 5600. Therefore, the safety, stability and reliability are higher.

[0089] It should be noted that when the transverse plate 5310 moves toward the sample injection area 5001, the swing block 5341 can rotate in the opposite direction by its own weight, so that the pressure rod 5346 releases the sample rack 5600 until the swing block 5341 rests on the second limit portion 5331; the third push block 5314 can be in contact with the swing block 5341 all the time, or the third push block 5314 can be in contact with the swing block 5341 after moving a certain distance with the transverse plate 5310. In addition, elastic elements such as tension springs and torsion springs can also be provided to make the swing block 5341 automatically swing upward, so that the pressure rod 5346 is lifted upward to release the sample rack 5600.

[0090] In some embodiments, the third push block 5314 can be integrally formed with the transverse plate 5310, and the third push block 5314 and the first limit portion 5311 can also form an L-shaped structure. Thus, the structure is simpler and more stable, and processing, manufacturing, installation, and adjustment are more convenient.

[0091] In some embodiments, an eccentric shaft 5342 and a first locking member 5343 for locking the eccentric shaft 5342 are provided on the swing block 5341. The eccentric shaft 5342 is parallel to the fourth rotating shaft 5345. A roller 5344 corresponding to the third push block 5314 is provided on the eccentric shaft 5342. The position of the roller 5344 can be adjusted by rotating the eccentric shaft 5342. A second limiting portion 5331 corresponding to the swing block 5341 is provided on the second bracket 5330. Among them, the first locking member 5343 can be one, two or more. The first locking member 5343 can be a fastener such as a locking screw, and the roller 5344 can be a nylon wheel or a bearing. Therefore, the position of the roller 5344 is adjusted by rotating the eccentric shaft 5342, and then the degree of compression of the sample rack 5600 by the pressing rod 5346 is adjusted, which makes the operation more convenient, quick, safer and more reliable.

[0092] In some embodiments, a pressing wheel 5347 is provided on the pressing rod 5346. The pressing wheel 5347 may be a rubber wheel, a silicone wheel, etc., which can provide buffer protection, reduce damage to parts, etc. Thus, the pressing wheel 5347 can better press the sample rack 5600, making it more stable and reliable.

[0093] In some embodiments, the second bracket 5330 is further provided with an avoidance groove 5332, the pressure rod assembly 5340 and the transverse plate 5310 are located in the avoidance groove 5332, and the second driving member 5320 is located on one side of the avoidance groove 5332. Thus, the structure is more compact and stable, and the operation is more convenient.

[0094] In some embodiments, there are two pressure rod assemblies 5340, one of which is close to the sample inlet area 5001 and the other is close to the sample outlet area 5002. The two pressure rod assemblies 5340 are connected by a connecting rod 5350, and the connecting rod 5350 is hinged to the two swing blocks 5341 respectively, so that the two swing blocks 5341 swing synchronously.

[0095] That is to say, during the sampling process of the sample rack 5600, at least one pressure rod 5346 of the pressure rod assembly 5340 presses the sample rack 5600, ensuring better pressing of the sample rack 5600, which is more stable and reliable. Moreover, only one third push block 5314 is required on the transverse plate 5310. The third push block 5314 corresponds to the swing block 5341 of one of the pressure rod assemblies 5340. When one of the swing blocks 5341 swings, the other swing block 5341 is driven to swing synchronously through the connecting rod 5350. The structure is simpler and more stable, and the operation is more convenient.

[0096] In some embodiments, the sample discharging mechanism 5400 includes a third driving member 5410 and a push plate 5420. The third driving member 5410 is located below the carrier plate 5120, and the push plate 5420 is usually located above one end of the sample discharging channel 5123 close to the transverse channel 5122. The third driving member 5410 is connected to the push plate 5420, and the third driving member 5410 drives the push plate 5420 to move, so that the push plate 5420 pushes the sample rack 5600 corresponding to the transverse channel 5122 in the sample discharging channel 5123 along the sample discharging channel 5123 to the end away from the transverse channel 5122 by a distance of one sample rack 5600. As a result, the structure is simpler, more compact, smaller in size, and more convenient to operate.

[0097] It should be noted that the second driving member 5320 and the third driving member 5410 can refer to the structure of the above-mentioned first driving member 5220, and the second driving member 5320 can also drive the transverse plate 5310 to reciprocate along the corresponding linear slide rail through the corresponding transmission mechanism, and the third driving member 5410 can also drive the push plate 5420 to reciprocate along the corresponding linear slide rail through the corresponding transmission mechanism. These will not be described in detail here.

[0098] In some embodiments, the support assembly 5100 may also be provided with a detector for detecting and identifying the sample cup on the sample rack 5600. The detector is located near the sample suction station and may be a barcode scanner, etc. The detector is not shown in the drawings. Thus, the detector first scans and identifies the reaction cup on the sample rack 5600 to be sampled, and determines the relevant information of the reaction cup, which is safer and more reliable.

[0099] Based on the above-mentioned embodiments of the present disclosure, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0100] The above are only some embodiments of the present application, which are only used to illustrate the technical solution of the present application, rather than to limit it. It should be understood that, for those skilled in the art, without departing from the creative concept of the present application, it is possible to improve or replace it according to the above description, and all these improvements and replacements should belong to the protection scope of the claims attached to the present application. In this case, all details can be replaced by equivalent elements, and the materials, shapes and sizes can also be arbitrary.
