DETAILED DESCRIPTION

[0024] The following is a more detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and the accompanying drawings so that a person skilled in the art can implement the embodiments after reading the description. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The present invention provides Figure 1 A coagulation analyzer providing an online interface is shown, comprising a reagent chamber module 1, a detection module 2, a needle movement module 3, a needle cleaning module 4, a reaction cup transport module 5, a sample inlet 741 and a power control module 6 connected to the signals of the above modules, and also comprising a sample transport module 7, wherein the sample transport module 7 comprises a second sample injection track 71, a transverse track 72 and a sample output track 73 connected in sequence; one end of the second sample injection track 71 is provided with a first sample online port 711 connected to the online track, and the sample output track 73 is provided with a second sample online port 731 connected to the online track; the second sample injection track 71 is provided with a sampling blocking device 712 at one end facing the transverse track 72; the first sample online port 711 and the end of the transverse track 72 facing the sample output track 73 are both provided with a transfer device 8, and the first sample online port 711 is also provided with a first blocking device 713.

[0026] In the existing coagulation analyzer, the blood sample rack extends from the sample inlet into the coagulation analyzer, and the needle movement module can move freely inside the coagulation analyzer to add the blood sample in the sample rack or the reaction reagent in the reagent compartment module to the reaction cup in the detection module. In the detection module, the blood sample is processed and tested by the dual magnetic circuit magnetic bead method, transmission turbidimetry or chromogenic substrate method to finally obtain the test result; the needle cleaning module is used to clean the needle movement module to prevent the blood sample from being contaminated; the reaction cup transport module is used to transport the reaction cup for the detection module to take, and one reaction cup is required for each test.

[0027] In order to connect with the online track, the present invention is also provided with a sample transport module, and the sample rack carrying the blood sample tube can enter the sample transport module from the online track, and return to the online track from the sample transport module after sampling. The sample transport module includes a second sample inlet track, a transverse track and a sample outlet track, and the above tracks are connected in sequence.

[0028] One end of the second sample introduction track is connected to the transverse track, and the other end is provided with a first sample connection port connected to the online track; the first sample connection port is also provided with a transfer device and a first blocking device, and the first blocking device can be arranged on the top of the transfer device. When the sample rack on the online track needs to enter the coagulation analyzer for inspection, the first blocking device blocks the sample rack, and the transfer device transfers the sample rack to the second sample introduction track. The sample rack moves toward the transverse track on the second sample introduction track and is temporarily blocked by the sampling blocking device to create a stable environment for sampling; when the sampling is completed, the sampling blocking device is released, and the sample rack is pushed to the transverse track by the second sample introduction track, and then pushed to the sample outlet track by the transfer device arranged on the transverse track toward one end of the sample outlet track. The sample outlet track is provided with a second sample connection port connected to the online track.

[0029] When the present invention is used in conjunction with the online track, the sample rack on the online track is transferred to the second sample introduction track by the transfer device arranged on the first sample online port. After completing the inspection of all sample tubes on the sample rack, the second sample introduction track sends the sample rack to the transverse track, and then is pushed to the sample outlet track by the transfer device arranged on the transverse track toward one end of the sample outlet track, and then returns to the online track through the sample outlet track, and is sent to the next detection instrument by the online track. In addition, the present invention retains the conventional sample inlet, and the sample rack can be manually sent from the sample inlet to the first sample introduction track, and enter the second sample track through the transition track.

[0030] After adding the sample transport module, the position and layout of other modules of the coagulation analyzer also need to be adjusted to adapt to the new sampling mode. The reagent compartment module loaded with reaction reagents, the detection module that performs specific detection items, the reaction cup transport module for transporting reaction cups, and the needle movement module for collecting samples and reaction reagents are closely connected and should be arranged in a centralized manner. Figure 1 As shown, in one embodiment, the second sample injection track, the transverse track and the sample output track can be connected to form a U shape, enclosing the reagent compartment module, the detection module, the reaction cup transport module and the needle cleaning module. The needle movement module is arranged on the top of the second sample injection track, the reagent compartment module, the detection module, the reaction cup transport module and the needle cleaning module, and the sampling working range needs to cover the newly added second sample injection track. The power control module is arranged on the outside of the transverse track for easy maintenance.

[0031] Preferably, the sample transport module 7 also includes a first sample injection track 74, which is arranged on the outside of the second sample injection track 71 and is provided with the sample inlet 741; a transition track 75 is connected between the first sample injection track 74 and the second sample injection track 71; guide walls 76 are provided on both sides of the first sample injection track 74, the transition track 75, the second sample injection track 71, the transverse track 72 and the sample output track 73; an emergency sample position 11 is provided on the side of the reagent chamber module 1 away from the transverse track 72.

[0032] In addition to the sample rack entering from the online track, in one embodiment, the present invention also retains the conventional sample inlet. Figure 1 As shown, the first sample introduction track can be set on the side of the second sample introduction module away from the sample outlet track, closer to the outside of the entire coagulation analyzer, which is convenient for setting the sample inlet; the blood sample rack can be manually operated to enter the first sample introduction track from the sample inlet, and then enter the second transverse track through the transition track.

[0033] The sample holder generally has a large aspect ratio and its angle remains constant during movement. Figure 1 As shown, the sample rack can move along the online track along its length direction, and the online track can extend in the transverse direction. When the sample rack enters the first sample inlet track, the second sample inlet track and the sample outlet track in the vertical direction, it moves along its width direction. Therefore, the first sample inlet track, the second sample inlet track and the sample outlet track are relatively wide; and when the sample rack enters the transition track and the transverse track in the transverse direction, it moves along its length direction. The transition track and the transverse track are relatively narrow. The specific size of the above track can be determined according to the actual size of the sample rack and the coagulation analyzer.

[0034] The guide walls are arranged on both sides of the track to prevent the sample rack from falling or deviating from the direction and causing equipment failure. On the first sample inlet track, the second sample inlet track and the sample outlet track, the width between the two guide walls can be slightly larger than the length of the sample rack; on the transition track and the transverse track, the width between the two guide walls can be slightly larger than the width of the sample rack. The guide walls can be made of stainless steel.

[0035] like Figure 1As shown, an emergency sample position is provided on the side of the reagent compartment module away from the transverse track for emergency testing.

[0036] Preferably, the first sample feeding track 74, the transition track 75, the second sample feeding track 71, the transverse track 72 and the sample discharging track 73 all include a support plate 77 and a conveying device 78 for conveying a sample rack; the conveying device 78 includes a guide rod 781, a slider 782 slidably connected to the guide rod 781 and a first power device 783 for driving the slider 782 to slide along the guide rod 781, the slider 782 is provided with a base 784, a push plate 785 is rotatably connected to the base 784, and a limit plate 787 is provided on the base 784 for limiting the push plate 785 to rotate in only one direction, a torsion spring 786 is also provided between the base 784 and the push plate 785, and the end of the push plate 785 is wedge-shaped; the first power device 783 is signal-connected to the power control module 6.

[0037] like Figure 2 and Figure 3 As shown, the first sample feeding track, transition track, second sample feeding track, transverse track and sample discharging track all include a support plate and a conveying device. The support plate is used to support the sample rack and provides a plane extending along a straight line for the movement of the sample rack. The conveying device pushes the sample rack to move linearly along the support plate and the guide wall. The conveying device includes a guide rod, a slider, a first power device, a base, a push plate, a limit plate and a torsion spring. The guide rod determines the movement trajectory of the sample rack, which is generally the same as the extension direction of the support frame. The slider is slidably connected to the guide rod and is used to carry the base and the push plate. The first power device provides power to the slider so that the slider performs reciprocating linear motion on the guide rod, including but not limited to a belt transmission device, a linear module, etc. The base is fixedly connected to the slider, the push plate is rotatably connected to the base, and a torsion spring is also arranged between the push plate and the base, and the end of the push plate is wedge-shaped, so that the end of the push plate has a vertical surface and an inclined surface.

[0038] In the reset state of the torsion spring, the end of the push plate can be on the support plate and can contact the sample rack; when the push plate contacts the sample rack with an inclined surface during the movement, the friction between the sample rack and the support plate can force the push plate to rotate relative to the base, so that the push plate can pass over the sample rack, and at the same time, the torsion spring generates elastic potential energy. After the push plate passes over the sample rack, it resets under the action of the elastic potential energy of the torsion spring; when the push plate contacts the sample rack with a vertical surface during the movement, the limit plate can be set on the side of the base close to the inclined surface of the push plate to prevent the push plate from rotating, so that the push plate can push the sample rack to move. The inclined surface generated by the wedge can reduce the rotation angle of the push plate, thereby reducing the elastic potential energy generated by the torsion spring, and preventing the elastic potential energy from being too large so that the push plate cannot pass over the sample tube. The guide rod, slider, base, push plate, and limit plate can be made of stainless steel, and the torsion spring can be made of 65Mn spring steel.

[0039] Preferably, the support plate 77 is provided with at least one conveying slit 771; the conveying device 78 is arranged at the bottom of the support plate 77, and the end of the push plate 785 extends from the bottom of the support plate 77 through the conveying slit 771 for pushing the sample rack.

[0040] There are various positional relationships between the support plate and the conveying device. Figure 2 and Figure 3 As shown, in one embodiment, two conveying devices are located at the bottom of the support plate, and the support plate is provided with two conveying slits, so that the end of the push plate can extend out of the support plate through the conveying slits, so as to contact the sample rack. The first sample inlet track, the second sample inlet track, and the sample outlet track are preferably in this manner.

[0041] Preferably, the conveying device 78 is disposed on one side or both sides of the support plate 77, and the end of the push plate 785 extends from the side to the support plate 77 for pushing the sample rack.

[0042] In another embodiment, the conveying device is located on one or both sides of the support plate, and the end of the push plate extends from the side to the support plate so as to contact the sample rack. It is preferred that the transition track and the transverse track adopt this method.

[0043] Preferably, the transverse track 72 is a belt conveyor, and a first position sensor 721 and a second position sensor 722 are respectively disposed at two ends of the transverse track 72 .

[0044] In one embodiment, the transverse track is a belt conveyor. A first position sensor and a second position sensor are respectively disposed at both ends of the transverse track, and both are connected to the power control module signal. In one embodiment, the first position sensor can be disposed at one end of the transverse track facing the second injection track, and the second position sensor can be disposed at the other end of the transverse track. Figure 3 and Figure 4When the sample rack is pushed to the transverse track by the second sample track, the first position sensor sends a signal to the power control module to control the transverse track to start rotating, and transport the sample rack to one end close to the sample output track, touching the second position sensor, and the second position sensor sends a signal to the power control module to control the transverse track to stop rotating, so that the transfer device can push the sample rack into the sample output track. The first and second position sensors can use travel switches.

[0045] Preferably, the sampling blocking device 712 includes a blocking structure 9 and a third position sensor 714; the blocking structure 9 includes a hollow base 91, a second power device, a driving gear 92 and a blocking member 93, a guide bar 94 is provided on the base 91, a slide groove 95 is provided on the side of the blocking member 93 facing the guide bar 94, and the slide groove 95 and the guide bar 94 are slidably connected; the second power device is arranged in the base 91, the driving gear 92 is arranged on the output shaft of the second power device, and a rack 96 is provided on the side of the blocking member 93 facing the driving gear 92, and the rack 96 is meshed with the driving gear 92; the third position sensor 714 is arranged on the side of the sampling blocking device 712 facing the second sample introduction track 71, and the third position sensor 714, the second power device and the power control module 6 are signal-connected.

[0046] like Figure 3 As shown, in one embodiment, the sampling blocking device is arranged at one end of the second sample track facing the transverse track, including a blocking structure and a third position sensor. The blocking structure can block and release the sample rack, including a base, a second power device, a driving gear and a blocking member. The base is hollow inside and is provided with a second power device, whose output shaft protrudes from the base and is provided with a driving gear. A guide bar is provided on the base, and the blocking member is slidably connected to the guide bar through a slide groove, and the length of the slide groove is greater than the length of the guide bar. A rack meshing with the driving gear is also provided on the blocking member, and the second power device drives the blocking member to slide along the guide bar through the driving gear. When the blocking member slides onto the second sample track, the sample rack can be blocked. The base, the driving gear, the blocking member and the guide bar can be made of stainless steel, and the second power device can be a micro stepping motor, and is connected to the power control module signal.

[0047] The third position sensor is connected to the power control module by signal, and its detection direction is toward the sample rack on the second sample track. The third position sensor can be a photoelectric position sensor, and the signal changes before and after the sample rack passes through the third position sensor. In the reset state, the blocking member is on the transverse track to block the sample rack. After the sampling and inspection are completed, the second power device receives the signal and starts to drive the blocking member away from the transverse track to allow the sample rack to pass. After the sample rack completely passes through the third position sensor, the third position sensor sends a signal to the power control module to control the second power device to rotate in the opposite direction to drive the blocking member to reset.

[0048] Preferably, the first blocking device 713 includes the blocking structure 9 and a fourth position sensor 715 , the fourth position sensor 715 is arranged on a side of the first blocking device 713 facing the online track, and the fourth position sensor 715 is signal-connected to the power control module 6 .

[0049] like Figure 5 As shown, in one embodiment, the first blocking device includes a blocking structure similar to the sampling blocking device and a fourth position sensor. The first sample online port is arranged on one side of the online track, and the first blocking device is arranged on the other side of the online track at a position corresponding to the first sample online port, and can be fixedly connected to the first sample online port by a bracket to form a U-shaped opening structure, so that the online track passes through it. There can be two blocking structures, corresponding to the guide walls on both sides of the first sample online port.

[0050] The fourth position sensor can be a photoelectric position sensor, which is connected to the power control module signal to detect whether a sample rack passes on the online track. When a sample rack passes, a signal is sent to the power control module to control the two blocking structures to extend the blocking members to block the sample rack and prevent the next sample rack from entering.

[0051] Preferably, the transfer device 8 includes a mounting seat 81, a mounting groove is provided in the mounting seat 81, a pushing device is provided in the mounting groove, the pushing device includes a pushing handle 82, a telescopic arm 83 is provided between the pushing handle 82 and the side wall of the mounting groove, and the telescopic arm 83 is signal-connected to the power control module 6.

[0052] In one embodiment, the transfer device includes a mounting seat and a pushing device. The pushing device is arranged in a mounting groove on the side of the mounting seat facing the online track, and includes a push handle and a telescopic arm. The telescopic arm can be extended so that the push handle pushes the sample rack to the online track or the sample output track. The telescopic arm can be an electric push rod, and is connected to the power control module signal; the push handle can be made of stainless steel into a long strip, and the vertical height of the push handle and the telescopic arm can be slightly lower than the center of gravity of the sample rack to prevent the sample rack from tipping over during the pushing process. The mounting seat and the blocking plate can be made of stainless steel.

[0053] like Figure 4 As shown, the transfer device is provided at the connection between the transverse track and the sample delivery track. When the second position sensor detects the presence of the sample rack, the power control module first stops the transverse track, then starts the transfer device, and pushes the sample rack to the sample delivery track. After the push handle is fully retracted, the blocking member of the first blocking device can be controlled to be retracted. Figure 6 As shown, the transfer device can be arranged at the bottom of the first blocking device. When the fourth position sensor detects the sample rack, the power control module controls the blocking structure to intercept the sample rack, and then starts the transfer device to push the sample rack into the second sample track. The pushing amount of the transfer device can leave a certain margin for the push plate of the conveying device to prevent the sample rack at the end of the track from blocking the push plate from extending.

[0054] Preferably, a second blocking device 751 is also provided at the junction of the transition track 75 and the second injection track 71 and on the side facing the online track; the second blocking device 751 includes the blocking structure 9 and a fifth position sensor 752; the fifth position sensor 752 is arranged on the guide wall 76 of the second injection track 71 at a position corresponding to the transition track 75; the fifth position sensor 752 is signal-connected to the power control module 6.

[0055] The sample rack entering from the online track may conflict with the sample rack entering from the first sample introduction track in the conventional manner, causing equipment failure. To avoid such failure, a second blocking device is provided on the transition track. Figure 7 As shown, the second blocking device includes a blocking structure similar to the sampling blocking device and a fifth position sensor. The fifth position sensor can be a photoelectric position sensor, which is connected to the power control module signal to detect whether there is a sample rack at the exit position of the second injection track on the transition track. In the reset state, the blocking member of the second blocking device is away from the transition track, which facilitates the passage of the sample on the transition track; when the fifth position sensor detects the sample rack, it transmits a signal to the power control module to control the blocking structure to extend the blocking member to the transition track to prevent the transition track from continuing to push the sample rack. When the sample rack on the second injection track passes the fifth position sensor, the fifth position sensor transmits a signal to the power control module to control the blocking structure to reset.

[0056] The above are one or more embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
