[0073] The application discloses a reaction cup selection device, realizes mechanical automatic selection of cups, improves the selection efficiency of the reaction cup selection device, and reduces the labor intensity. In addition, the application also discloses a full-automatic coagulation analyzer with the reaction cup selection device.

[0074] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0075] Hereinafter, the terms "first", "second", "third", etc. are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0076] The fully automatic coagulation analyzer is an important in-vitro diagnostic device, which is widely used in clinical examination of large hospitals. The improvement of the automation degree and the detection speed of the fully automatic coagulation analyzer puts forward higher requirements for the selection efficiency of the reaction cup selection system.

[0077] As shown in Figure 1 The reaction cup selection device of the fully automatic coagulation analyzer disclosed in the present application specifically comprises: a cup selection bin assembly 1, a top plate transmission assembly 2 and a reaction cup conveying assembly 3. The cup selection bin assembly 1 is used for storing reaction cups. The top plate transmission assembly 2 can be in communication with the cup selection bin assembly 1 and can make some reaction cups of the cup selection bin assembly 1 fall into the top plate transmission assembly 2. Under the action of the reaction cup conveying assembly 3, the reaction cups in the top plate transmission assembly 2 can be conveyed to a preset position.

[0078] From the above description of the functions of each component, it can be known that the cup selection bin assembly 1 in the present application is a fixed structure, and the top plate transmission assembly 2 can move relative to the cup selection bin assembly 1. In some embodiments, the top plate transmission assembly 2 is located below the cup selection bin assembly 1, so the top plate transmission assembly 2 can move up and down relative to the cup selection bin assembly 1. In addition, the reaction cup conveying assembly 3 is located at the side of the cup selection bin assembly 1, and the reaction cup conveying assembly 3 is arranged obliquely relative to the cup selection bin assembly 1. In view of this, in order to enable the reaction cups in the top plate transmission assembly 2 to enter the reaction cup conveying assembly 3, the top plate transmission assembly 2 can rotate relative to the reaction cup conveying assembly 3.

[0079] Through the above setting, when cup selection is needed, the reaction cups enter the cup selection bin assembly 1, and a part of the reaction cups will fall into the accommodation space of the top plate transmission assembly 2. The top plate transmission assembly 2 is started to move the accommodation space to the direction close to the cup selection bin assembly 1 until the reaction cups that fall on the accommodation space but do not enter the accommodation space fall into the cup selection bin assembly 1, while ensuring that one end of the accommodation space of the top plate transmission assembly 2 is aligned with the reaction cup conveying assembly 3. Thereafter, the accommodation space of the top plate transmission assembly 2 is rotated relative to the reaction cup conveying assembly 3, so that the accommodation space of the top plate transmission assembly 2 is parallel to and in communication with the guide cup groove track of the reaction cup conveying assembly 3. Under the action of gravity, the reaction cups in the top plate transmission assembly 2 enter the guide cup groove track of the reaction cup conveying assembly 3, and the cup selection is completed.

[0080] After the cup selection is completed, the accommodating space of the top plate transmission assembly 2 needs to be reversely rotated and then moved away from the cup selection bin assembly 1 until the accommodating space of the top plate transmission assembly 2 is moved to the initial position, so as to complete the resetting process.

[0081] In the scheme, the automatic cup selection process is realized by using a mechanized structure, without human operation, so that the labor intensity is low and the cup selection efficiency is high.

[0082] As shown in Figures 2 to 4 The specific structure of the cup selection bin assembly 1 is disclosed in the present application, which specifically includes a cup selection hopper 11, a cup selection bin (not shown in the figure), a light coupling fixing block 13, a light coupling 14, a cup blocking guide plate 15, a hopper rear guide block 16, a hopper front guide block 17, and an anti-blocking block 18.

[0083] The cup selection hopper 11 is in communication with the cup selection bin, and the reaction cup to be selected can be put into the cup selection bin through the cup selection hopper 11, that is, the cup selection hopper 11 functions to deliver the reaction cup into the cup selection bin. In view of this, in order to improve the delivery convenience of the reaction cup, in some embodiments, the cup selection hopper 11 is provided in a funnel structure, and specifically, the opening end of the funnel structure has a cross-sectional size larger than that of the connecting end connected to the cup selection bin.

[0084] Since the cup selection bin in the present application is of a rectangular structure, correspondingly, the cross section of the cup selection hopper 11 is also of a rectangular cross section.

[0085] The cup selection bin includes a cup selection front baffle 121, a cup selection rear baffle 122, a cup selection right baffle 123, and a cup selection left baffle 124. The cup selection front baffle 121 and the cup selection rear baffle 122 are arranged in parallel and opposite to each other, and the cup selection right baffle 123 and the cup selection left baffle 124 are arranged in parallel and opposite to each other. The cup selection front baffle 121, the cup selection right baffle 123, the cup selection rear baffle 122, and the cup selection left baffle 124 are sequentially connected to form a rectangular frame structure. The frame structure is used to hold the out-of-order reaction cups. The upper end of the frame structure is in communication with the cup selection hopper 11, and the lower end side of the frame structure is in communication with the top plate transmission assembly 2.

[0086] In order to facilitate the observation of the number of reaction cups in the cup selection bin and the later maintenance, in some embodiments, the cup selection front baffle 121 is designed to be of a transparent material, and the cup selection front baffle 121 is designed to be of a convenient dismounting structure, for example, the cup selection front baffle 121 is inserted with the cup selection right baffle 123 and the cup selection left baffle 124.

[0087] Since the top plate transmission assembly 2 in the present application needs to communicate with the cup selecting bin assembly 1, the right cup selecting baffle 123 and the left cup selecting baffle 124 in the present application are both provided with openings, and a channel accommodating the top plate transmission assembly 2 is formed between the right cup selecting baffle 123 and the left cup selecting baffle 124, and the lifting and rotation of the top plate transmission assembly 2 can be completed in the channel.

[0088] In order to make the reaction cup in the cup selecting bin smoothly enter the accommodating space of the top plate transmission assembly, the present application is provided with a hopper rear guide block 16 and a hopper front guide block 17 on the two opposite side walls of the channel, as shown in Figure 3 The hopper rear guide block 16 and the hopper front guide block 17 are both plate members arranged obliquely relative to the channel. The oblique arrangement of the hopper rear guide block 16 and the hopper front guide block 17 can make the reaction cup slide into the accommodating space of the top plate transmission assembly 2 under the action of gravity.

[0089] In some embodiments, the inclination angle a of the hopper front guide block 17 relative to the horizontal plane can be set to 15°-23°, and the inclination angle β of the hopper rear guide block 16 relative to the horizontal plane can be set to 15°-23°. In some embodiments, the inclination angles of the hopper front guide block 17 and the hopper rear guide block 16 can be set to be the same, for example, both 18°.

[0090] Figure 2 And Figure 4 The mounting positions of the light reflection coupling fixed block 13 and the light reflection coupling 14 are shown in Figs. 7 and 8. Specifically, the light reflection coupling fixed block 13 is fixedly installed on the right cup selecting baffle 123 and the left cup selecting baffle 124, and the light reflection coupling 14 is fixedly installed on the light reflection coupling fixed block 13.

[0091] It should be noted that the light reflection coupling 14 is installed at a position close to the bottom of the cup selecting bin to detect and feed back whether there is a reaction cup in the cup selecting bin. When the light of the light reflection coupling 14 is blocked, it means that there is a reaction cup in the cup selecting bin. When the light of the light reflection coupling 14 is not blocked, it means that there is no reaction cup in the cup selecting bin. By setting two groups of light reflection couplings 14, the detection accuracy can be improved.

[0092] In some embodiments, two light reflection couplings 14 are provided on the light reflection coupling fixed block 13. Any one of the light couplings has a problem, and the other light coupling can be used instead, so that the detection accuracy can be improved.

[0093] In addition, the cup blocking guide plate 15 and the anti-blocking block 18 in the cup selecting bin assembly 1 need to be described in combination with the top plate transmission assembly 2. Here, the mounting positions are described first.

[0094] The blocking cup guide plate 15 is a plate member fixed to the left blocking plate 124 of the cup selection, and specifically, there is a gap between the blocking cup guide plate 15 and the left blocking plate 124 of the cup selection, and specifically, the blocking cup guide plate 15 can be a U-shaped member, and the blocking cup guide plate 15 is installed above the channel.

[0095] The anti-blocking block 18 is fixed in the cup selection bin, and the anti-blocking block 18 is a wedge-shaped block, and the size of the end close to the bottom of the cup selection bin is smaller than the size of the end away from the bottom of the cup selection bin.

[0096] As shown in Figure 5 and Figure 6 , wherein, Figure 5 is a structural schematic diagram of the top plate transmission assembly in the first state, Figure 6 is a structural schematic diagram of the top plate transmission assembly in the second state. The top plate transmission assembly 2 in the application specifically includes: a top plate assembly 21, a cup selection movement assembly 22, and a flexible blocking cup assembly 23. The cup selection movement assembly 22 is a mounting base, the top plate assembly 21 can be lifted and rotated relative to the cup selection movement assembly 22, and the flexible blocking cup assembly 23 is hinged to the top plate assembly 21 and can be rotated relative to the top plate assembly 21.

[0097] Figure 7 The specific structure of the top plate assembly 21 is shown, including: a first top plate 211, a second top plate 212, and a top plate clamping block 213. The first top plate 211 and the second top plate 212 are arranged opposite and parallel, and the top plate clamping block 213 is located between the first top plate 211 and the second top plate 212 and is fixed at a position close to the bottom of the first top plate 211 and the second top plate 212. In this way, a containing space for accommodating the reaction cup 4 is formed between the first top plate 211 and the second top plate 212 and above the top plate clamping block 213.

[0098] It should be noted that the size of the containing space can be set according to the length of the first top plate 211 and the second top plate 212, and the distance between the first top plate 211 and the second top plate 212 needs to be greater than the diameter of the reaction cup 4 and less than one fifth of the diameter of the reaction cup (the maximum distance between the first top plate 211 and the second top plate 212 can be set according to actual needs), so as to ensure that the reaction cup 4 is arranged in a single row and in a straight line in the containing space.

[0099] The specific shape of the first top plate 211 and the second top plate 212 can not be limited, and can be designed according to the setting of the entire reaction cup selection device.

[0100] Figure 8 and Figure 9 The specific structure of the cup selection movement assembly 22 is shown, and in combination with Figures 13 to 19The cup selecting motion assembly 22 comprises a cup selector mounting base plate 2201, a cup selector mounting support plate 2202, a cup selector fixing plate 2203, a motor fixing plate 2204, a stepping motor 2205, a linear guide rail 2206, a driving slider fixing seat 2207, a driven slider fixing seat 2208, a slider seat connecting rod 2209, a cup seat fixing block 2210, a cup seat connecting rod 2211, a bearing follower 2212, a synchronous pulley 2213, a synchronous belt 2214, a pulley connecting plate 2215, a origin photoelectric coupler 2216 and a cam groove 2217.

[0101] Specifically, the cup selector mounting base plate 2201 serves as the mounting base of the entire cup selecting motion assembly 22, and its shape and size can be set according to different needs. The cup selector fixing plate 2203 is fixedly arranged on the cup selector mounting base 2201, and specifically, the cup selector fixing plate 2203 is vertically mounted on the cup selector mounting base plate 2201. In order to ensure the stability of the mounting of the cup selector fixing plate 2203 on the cup selector mounting base plate 2201, the cup selector mounting support plate 2202 is arranged in the present application, and specifically, the cup selector mounting support plate 2202 is a right-angled triangle, one of the right-angled sides is fixedly connected with the cup selector mounting base plate 2201, and the other right-angled side is fixedly connected with the cup selector fixing plate 2203 (see Figure 5 and Figure 6 ). The cup selector mounting support plate 2202 can increase the strength of the connection between the cup selector fixing plate 2203 and the cup selector mounting base plate 2201.

[0102] In some embodiments, one cup selector mounting support plate 2202 can be arranged at each end of the cup selector fixing plate 2203.

[0103] The cup selector mounting base plate 2201, the cup selector fixing plate 2203 and the cup selector mounting support plate 2202 form the mounting bracket of the entire cup selecting motion assembly 22, and their sizes and shapes are not limited.

[0104] The linear guide rail 2206 and the cam groove 2217 are fixedly arranged on the cup selector fixing plate 2203, and specifically, the linear guide rail 2206 and the cam groove 2217 are arranged in the vertical direction, and the straight line segment of the cam groove 2217 is parallel to the linear guide rail 2206.

[0105] The linear guide rail in the present application is a double-sliding-block linear guide rail. Specifically, an upper sliding block (not shown in the figure) and a lower sliding block (not shown in the figure) are arranged on the linear guide rail. The lower sliding block of the linear guide rail 2206 is connected with the driving sliding block fixing seat 2207, and the upper sliding block of the linear guide rail 2206 is fixedly connected with the driven sliding block fixing seat 2208. Under the action of the upper sliding block and the lower sliding block, the driving sliding block fixing seat 2207 and the driven sliding block fixing seat 2208 can be lifted along the linear guide rail 2206. One end of the cup selection seat connecting rod 2211 is connected with the driven sliding block fixing seat 2208, the other end is connected with the cam groove 2217 through the bearing follower 2212, and the cup selection seat connecting rod 2211 is connected with the driving sliding block fixing seat 2207 through the sliding block seat connecting rod 2209. In this way, the driving sliding block fixing seat 2207, the driven sliding block fixing seat 2208, the sliding block seat connecting rod 2209 and the cup selection seat connecting rod 2211 form a connecting rod structure.

[0106] The first top plate 211 of the top plate assembly 21 described above is hinged to one end of the cup selection seat connecting rod 2211 close to the linear guide rail 2206, and the other end is connected to one end of the cup selection seat connecting rod 2211 close to the cam groove 2217.

[0107] It should be noted that the structure of the cam groove 2217 is that the lower end is a straight line segment and the upper end is a circular arc segment, and the function is to guide the bearing follower 2212 to complete vertical and rotary motion. The length of the straight line segment of the cam groove 2217 is the same as the length of the linear guide rail 2206, and the position where the circular arc segment is connected with the straight line segment is the same as the position of the end of the linear guide rail 2206.

[0108] In addition, a motor fixing plate 2204 is also fixed on the cup selector fixing plate 2203, and a stepping motor 2205 is fixed on the motor fixing plate 2204. In addition, a rotatable synchronous pulley 2213 is also arranged on the cup selector fixing plate 2203, and the output shaft of the stepping motor 2205 is connected with the synchronous pulley 2213 through the synchronous belt 2214.

[0109] It should be noted that the stepping motor 2205 and the synchronous pulley 2213 in the present application are arranged in the vertical direction, and the synchronous belt 2214 is arranged in parallel with the sliding block seat connecting rod 2209. In addition, the synchronous belt 2214 and the sliding block seat connecting rod 2209 are rotatably connected through the pulley connecting plate 2215. In this way, the sliding block seat connecting rod 2209 can be lifted through the synchronous belt 2214. Of course, other driving assemblies can also be used to drive the cup selection seat connecting rod 2211 to lift and rotate in other embodiments.

[0110] The selected cup movement assembly 22 works: start the stepper motor 2205, so that the synchronous belt 2214 and the synchronous pulley 2213 synchronous rotation, in turn, drive the slider seat connecting rod 2209 along the linear guide 2206 to do the rising movement, in turn, drive the selected cup seat connecting rod 2211 to rise, realize the rising movement of the top plate assembly 21 connected with the selected cup seat connecting rod 2211, until the end of the top plate assembly 21 is flush with one end of the reaction cup conveying assembly 3, that is, the vertical movement of the top plate assembly 21 is realized.

[0111] When the stepper motor 2205 continues to drive, because the selected cup seat connecting rod 2211 has moved to the end of the linear guide 2206, the selected cup seat connecting rod 2211 will rotate around the linear guide 2206 along the circular segment of the cam groove 2217, thereby realizing the rotation of the top plate assembly 21.

[0112] The reverse movement of the top plate assembly 21 will first rotate and then move downward in the vertical direction. The specific driving process is referred to the rotation and vertical movement described above, only the rotation direction of the stepper motor is changed, which will not be described here.

[0113] In order to realize the selected cup abnormal automatic processing function, the stepper motor 2205 used by the selected cup movement assembly 22 is a motor with an encoder, the encoder is coaxially arranged with the stepper motor 2205, can obtain the rotation angle of the stepper motor, in normal work, a preset pulse is input to the stepper motor 2205, the rotation angle of the stepper motor 2205 obtained by the encoder is the rotation angle corresponding to the preset pulse; When the rotation angle of the stepper motor 2205 obtained by the encoder is less than the rotation angle corresponding to the preset pulse, it indicates that the stepper motor 2205 has a step loss. Through the encoder, whether the stepper motor 2205 has a step loss is monitored in real time, and when the step loss occurs, it indicates that the outlet has a cup jamming condition, then the control device executes an automatic recovery instruction to control the flexible cup blocking assembly 23 to move up and down to vibrate the abnormal reaction cup 4 down, realizing the selected cup abnormal automatic recovery function.

[0114] The original point photocoupler 2216 is designed at the lowest position of the linear guide 2206, which can detect the position of the driven slider fixed seat 2207. When the light of the original point photocoupler 2216 is blocked, it indicates that the driven slider fixed seat 2207 is at the initial position. When the light of the original point photocoupler 2216 is not blocked, it indicates that the driven slider fixed seat 2207 has left the initial position.

[0115] It should be noted that the position of the original point photocoupler 2216 is the initial position of the selected cup movement assembly 22, which is the original reference position for the movement and rotation of the top plate assembly 21. When the cup jamming condition occurs, the selected cup movement assembly 22 needs to return to the initial position.

[0116] As Figure 10 andFigure 11 The specific structure of the flexible blocking cup assembly 23 is shown, including: a blocking cup fixing block 231, a first assembly surface 232, a second assembly surface 233, a hinge fixing block 234, and a blocking cup plate 235.

[0117] The main function of the flexible blocking cup assembly 23 is to ensure that the cup outlet of the cup selection movement assembly 21 is in a closed state when the top plate assembly 21 moves vertically, thereby preventing the reaction cup 4 from leaking into the instrument.

[0118] Specifically, the first assembly surface 232 and the second assembly surface 233 are arranged opposite and parallel to each other, and the hinge fixing block 234 is fixedly arranged between the first assembly surface 232 and the second assembly surface 233. The blocking cup plate 235 is hingedly connected to one end of the first assembly surface 232 and the second assembly surface 233. Specifically, the blocking cup plate 235 is rotatably arranged between the first assembly surface 232 and the second assembly surface 233, and the blocking cup plate 235 has a rotation gap with the hinge fixing block 234 to avoid friction between the blocking cup plate 235 and the hinge fixing block 234 when the blocking cup plate 235 rotates.

[0119] When the top plate transmission assembly 2 is assembled, the blocking cup plate 235 is inserted into the gap between the blocking cup guide plate 15 and the left blocking plate 124 of the cup selection movement assembly 22, and the blocking cup plate 235 can move up and down in the gap. That is, the function of the blocking cup guide plate 15 is to limit the movement of the blocking cup plate 235 in the horizontal plane.

[0120] The other end of the second assembly surface 233 is provided with a waist-shaped hole 236 (see Figure 16 and Figure 19 ). The second assembly surface 233 is fixed on the second top plate 212 of the top plate assembly 21 through the blocking cup fixing block 231. Specifically, one end of the blocking cup fixing block 231 is fixedly connected with the second top plate 212, and the other end of the blocking cup fixing block 231 is connected with the waist-shaped hole 236 of the second assembly surface 233.

[0121] In some embodiments, the waist-shaped hole 236 can also be arranged at the corresponding position of the first assembly surface 232, and the waist-shaped hole of the first assembly surface 232 is opposite to the waist-shaped hole of the second assembly surface 233.

[0122] The first assembly surface 232 is installed on the cup selection seat fixing block 2210 of the cup selection movement assembly 22. Specifically, the mounting portion of the cup selection seat fixing block 2210 is movably assembled into the waist-shaped hole of the first assembly surface 232.

[0123] In combination with Figures 14 to 16As shown, the structure of the flexible cup baffle assembly 23 in the first state is disclosed. Specifically, in the first state, the top plate assembly 21 does not rotate relative to the cup selection chamber assembly. At this time, the first mounting surface 232 and the second mounting surface 233 are perpendicular to the upper surface of the top plate assembly 21, and the first mounting surface 232 and the second mounting surface 233 are parallel to the left baffle 124 of the cup selection chamber. In this state, the hinge fixing block 234 and the cup baffle 235 do not rotate relative to each other. The hinge fixing block 234 blocks the outlet of the top plate assembly 21 (not shown in the figure), which is the port where the top plate assembly 21 is connected to the reaction cup conveying assembly 3.

[0124] The flexible baffle assembly 23 prevents the reaction cup from leaking directly into the instrument.

[0125] Combination Figures 17 to 19 As shown, the structure of the flexible cup baffle assembly 23 in the second state is disclosed. Specifically, in the second state, the top plate assembly 21 rotates relative to the cup selection chamber assembly 1. At this time, the hinge fixing block 234 rotates relative to the cup baffle plate 235, and the hinge fixing block 234 rotates relative to the outlet. In this state, the hinge fixing block 234 no longer blocks the outlet of the top plate assembly 21.

[0126] The flexible cup baffle assembly 23 opens to allow the reaction cup 4 to slide out of the cup selection chamber assembly 1 and into the reaction cup conveying assembly 3, thus completing the cup transfer.

[0127] Combination Figure 20 When a reaction cup 4 is stuck at the outlet, the size of the outlet can be adjusted by adjusting the installation position of the baffle fixing block 231 in the waist-shaped hole 236 of the second assembly surface 233, thereby releasing the stuck reaction cup 4.

[0128] like Figure 12 As shown, the reaction cup delivery assembly 3 in this application includes a guide cup track 31, a track fixing block 32, a first-end through-beam optical coupler 33, a first-end through-beam optical coupler fixing block 34, an end through-beam optical coupler 35, and an end through-beam optical coupler fixing block 36.

[0129] The guide cup rail 31 has a groove structure, and the groove can be used to accommodate reaction cups. It is necessary to ensure that the groove width of the guide cup rail 31 is slightly larger than the diameter of the reaction cup 4, so that the reaction cups can move along the groove and can only accommodate a single row of reaction cups. After installation, the guide cup rail 31 will be arranged at an angle relative to the selection cup assembly 1.

[0130] The groove rail fixing block 32 serves as a base and is fixedly connected to the lower part of the guide cup groove rail 31. The specific structure of the groove rail fixing block 32 can be set according to different needs, as long as it can support the guide cup groove rail 31.

[0131] In order to realize the orderly storage of the reaction cup, the cup guide rail 31 is designed as a long strip groove structure, and a light emitting diode is arranged at the head end and the tail end of the cup guide rail 31, wherein the head end is close to the cup outlet of the top plate assembly 21. The head end of the cup guide rail 31 is fixed with a head end light emitting diode fixing block 34, and the head end light emitting diode fixing block 34 is fixed with a head end light emitting diode 33. The tail end of the cup guide rail 31 is fixed with a tail end light emitting diode fixing block 36, and the tail end light emitting diode fixing block 36 is fixed with a tail end light emitting diode 35.

[0132] When the head end light emitting diode 33 and the tail end light emitting diode 35 are triggered, it indicates that the cup in the cup guide rail 31 is full, and the cup selection is stopped at this time. When the head end light emitting diode 33 and the tail end light emitting diode 35 are not triggered or only the tail end light emitting diode 35 is triggered, it indicates that the cup in the cup guide rail 31 is not full, and the cup selection is continued at this time. When only the head end light emitting diode 33 is triggered, it indicates that the cup guide rail 31 is abnormal, and the maintenance personnel is informed in time for maintenance.

[0133] Figures 14 to 19 The structure of the reaction cup selection device in the application in different working states is shown, wherein, Figures 14 to 16 The top plate assembly 21 rises to a position where it is flush with the reaction cup conveying assembly 3, at this time, the outlet of the top plate assembly 21 is blocked by the hinge fixing block 234, and the reaction cup 4 cannot pass through the outlet to enter the reaction cup conveying assembly 3; under the continuous driving of the stepping motor, the reaction cup selection device runs to Figure 17 The state shown, at this time, the top plate assembly 21 rotates to be parallel to the reaction cup conveying assembly 3, the outlet of the top plate assembly 21 is released by the hinge fixing block 234, and the reaction cup 4 passes through the outlet to enter the reaction cup conveying assembly 3.

[0134] In addition, the application also discloses a full-automatic coagulation analyzer, which comprises the reaction cup selection device, so that the full-automatic coagulation analyzer with the reaction cup selection device also has all the technical effects described above, which will not be repeated here.

[0135] The structure described above can be applied to the UR6000 full-automatic coagulation analyzer, but is not limited to this model of full-automatic coagulation analyzer.
