Description

Technical Field

[0001] The present invention relates to the technical field of blood testing, and in particular to an automatic thrombus detection device. Background Art

[0002] Thromboelastogram (TEG) is an indicator that reflects the dynamic changes of blood coagulation (including the formation rate of fibrin, the dissolution state and the firmness and elasticity of the coagulation). Therefore, the factors affecting the thromboelastogram mainly include: the aggregation state of red blood cells, the rigidity of red blood cells, the rate of blood coagulation, the activity of the fibrinolytic system, etc.

[0003] An important component of the existing thromboelastograph blood coagulation status detection component is the suspension wire, which is relatively thin and weak, easy to deform, and not easy to install and debug. At present, for blood testing, it is necessary to manually put the cup and cup lid filled with blood into the cup base, and manually lift the cup base upward.

[0035] like Figures 1 to 4 As shown, an embodiment of the present invention provides an automatic thrombus detection device, which is mainly used in the detection environment of thrombus in blood. The automatic thrombus detection device includes a base 100, a driving device 200, a pushing assembly 400, a supporting assembly 700 and a detecting assembly 500. The supporting assembly 700 is installed on the base 100, and is used to provide support for the supporting assembly 700 through the base 100. In addition, the position where the driving device 200 is installed on the base 100 is not specifically limited, and can be specifically set according to actual conditions. For example, the driving device 200 can be installed on the top of the base 100, the side wall of the base 100, or the inside of the base 100.

[0036] The pushing assembly 400 is provided with a placement groove 431 for placing the cup body 1000 , which is used to fix the cup body 1000 containing blood through the placement groove 431 to improve the stability of the cup body 1000 in the placement groove 431 .

[0037] In addition, the support assembly 700 includes a support plate 720 and a positioning rod 710, wherein the positioning rod 710 is disposed on the base 100, and the support plate 720 is connected to the positioning rod 710, and is used to fix the support plate 720 through the positioning rod 710, thereby improving the stability of the support plate 720. By vertically mounting the positioning rod 710 on the base 100, and movably mounting the support plate 720 above the positioning rod 710, and the support plate 720 and the positioning rod 710 are perpendicular to each other, the support plate 720 can slide along the axis direction of the positioning rod 710, and the height between the support plate 720 and the base 100 can be adjusted.

[0038] It should be noted that a height adjustment device 730 is detachably installed at the bottom of the support plate 720, and the height adjustment device 730 is mounted on the positioning rod 710. The height adjustment device 730 is used to provide support to the support plate 720 while adjusting the height of the support plate 720 on the positioning rod 710. The height adjustment device 730 includes a fixed base and a height adjustment member, the fixed base is mounted on the positioning rod 710, the height adjustment member is mounted on the positioning rod 710, and the height adjustment member is located on the side of the fixed base away from the support plate 720, and is used to adjust the height of the support plate 720 through the height adjustment member.

[0039] The detection assembly 500 includes a hanging wire 510 and a rocking rod 520, wherein the rocking rod 520 is connected to the support plate 720 through the hanging wire 510 and is located above the placement slot 431. Specifically, one end of the hanging wire 510 is installed at the bottom of the support plate 720 and is spaced apart from the positioning rod 710, and the hanging wire 510 is perpendicular to the support plate 720. At the same time, another section of the hanging wire 510 is installed at one end of the rocking rod 520, the rocking rod 520 is perpendicular to the support plate 720, and the axis of the hanging wire 510 coincides with the axis of the rocking rod 520, and the other end of the rocking rod 520 is located above the placement slot 431, so as to insert one end of the rocking rod 520 close to the placement slot 431 into the cup body 1000 located in the placement slot 431, so as to detect the blood in the cup body 1000.

[0040] The driving device 200 is connected to the pushing assembly 400 through a connecting piece 300, and is used to drive the pushing assembly 400 to move along the axis direction parallel to the positioning rod 710, so that the rocking rod 520 is inserted into the cup body 1000, and the blood in the cup body 1000 is detected. Or the driving device 200 drives the pushing assembly 400 away from the rocking rod 520. In addition, the driving device 200 can be a hydraulic cylinder, the model of which can be specifically selected according to actual conditions, and is used to drive the pushing assembly 400 to move along the axis direction parallel to the positioning rod 710 through the driving device 200.

[0041] Furthermore, the pushing assembly 400 can rotate with the connecting member 300, and is used to drive the cup body 1000 located in the placement groove 431 to rotate during the rotation of the pushing assembly 400, and drive the blood in the cup body 1000 to rotate. As the blood in the cup body 1000 gradually coagulates, the resistance to the rocking arm 520 will gradually increase, and the rocking arm 520 will be driven to rotate, and the elastic force of the blood is detected through the suspension wire 510 connected to the rocking arm 520.

[0042] It should be noted that the shape of the connecting member 300 is not specifically limited in the present invention. The connecting member 300 can be a connecting rod, a connecting plate, or a heterosexual connecting structure, which can be determined according to actual conditions.

[0043] like Figure 3 , Fig. 9 and Fig.10 As shown, in this embodiment, the cup body 1000 includes a cup body 1010 and a cup cover 1020, and the cup cover 1020 is movably installed at the opening of the cup body 1010. A protrusion 1021 is provided on the side of the cup cover 1020 close to the cup body 1010, and the length of the protrusion 1021 is greater than the depth of the cup body 1010, and a gap is formed between the bottom edge of the cup cover 1020 and the cup body 1010, thereby avoiding friction between the bottom edge of the cup cover 1020 and the cup body 1010 to generate resistance, thereby improving the accuracy of blood testing.

[0044] Among them, the protrusion 1021 is arranged on the central axis of the cup cover 1020, and the end of the protrusion 1021 away from the cup cover 1020 is arc-shaped. The arc shape of the protrusion 1021 forms point contact with the bottom of the cup body 1010, and further reduces the friction between the cup cover 1020 and the cup body 1010, thereby improving the accuracy of blood detection.

[0045] In addition, a slot 1022 is provided on the side of the cup cover 1020 away from the cup body 1010, and the swing arm 520 is matched with the slot 1022, and the swing arm 520 is fixed by the slot 1022. The slot 1022 is arranged on the axis of the cup cover 1020, and the slot 1022 corresponds to the swing arm 520 in a static state. It should be noted that the axis of the slot 1022 is the same as the axis of the protrusion 1021, the axis of the cup body 1010, the axis of the cup cover 1020 and the axis of the swing arm 520, so as to improve the accuracy of blood detection.

[0046] It should be noted that, in some embodiments of the present invention, when the blood in the cup body 1000 is detected by the detection component, the rocking arm 520 is inserted into the slot 1022 of the cup cover 1020, and the rocking arm 520 is fixed by the slot 1022, and the rocking arm 520 is driven to rotate by the cup cover 1020.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, in one embodiment of the present invention, in order to improve the accuracy of blood testing, a power mechanism 800 is provided on the support plate 720 , and the power mechanism 800 is used to drive the cup body 1000 to rotate.

[0048] The power mechanism 800 includes a first motor 810, a rotating base 820 and an adjusting rod 830; the first motor may be a DC motor, and its model may be specifically selected on the market according to actual conditions.

[0049] In addition, the rotating base 820 is movably mounted on the support plate 720, and a plurality of spaced arc holes 721 are provided on the support plate 720, and one arc hole 721 corresponds to one adjusting rod 830, and the adjusting rod 830 is limited by the arc hole 721, so as to control the rotation angle of the adjusting rod 830 through the arc hole 721, thereby improving the accuracy of the rotation angle of the adjusting rod 830.

[0050] By connecting the output end of the first motor 810 to the rotating base 820, the first motor 810 is used to drive the rotating base 820 to rotate, and the adjusting rod 830 is connected to the rotating base 820 to drive the adjusting rod 830 to swing during the rotation of the rotating base 820. It should be noted that in order to improve the stability between the adjusting rod 830 and the rotating base 820 and prevent the adjusting rod 830 from falling from the rotating base 820, the adjusting rod 830 is fixed to the rotating base 820.

[0051] Specifically, the adjusting rod 830 is sequentially arranged on the rotating base 820, the arc-shaped hole 721 and the pushing assembly 400, and is used to drive the pushing assembly 400 to swing during the swinging process through the adjusting rod 830, and drive the cup body 1000 located in the placement groove 431 to rotate during the swinging process of the pushing assembly 400. Specifically, the output end of the first motor 810 is installed in the middle of the rotating base 820, and is used to drive the rotating base 820 to rotate through the first motor 810, so that the swing amplitude of the adjusting rod 830 connected to the rotating base 820 is the same, and the pushing assembly 400 is driven to rotate through the adjusting rod 830, thereby improving the stability of the rotation of the pushing assembly 400.

[0052] It should be noted that the number of the adjustment rod 830 can be one. When the number of the adjustment rod 830 is one, the number of the arc-shaped hole 721 is at least one. One adjustment rod 830 passes through the rotating base 820, the arc-shaped hole 721 and the pushing assembly 400 in sequence, and the central angle corresponding to the maximum swing amplitude of the adjustment rod 830 in the arc-shaped hole 721 is 4°45′. Through the mechanical limit of the arc-shaped hole 721 and the combination of the first motor 810, the cup body 1010 is made to reciprocate at a uniform speed within the 4°45′ rotation angle range, thereby improving the test accuracy.

[0053] In addition, the number of the adjustment rods 830 can also be two or more than two. Specifically, the number of the arc-shaped holes 721 is not less than the number of the adjustment rods 830. Each adjustment rod 830 passes through the rotating base 820, an arc-shaped hole 721 and the pushing assembly 400 in sequence. Each adjustment rod 830 is fixed to the rotating base 820 and is used to drive the adjustment rod 830 to swing in the arc-shaped hole 721 during the process of driving the rotating base 820 to rotate by the first motor 810. And the swing direction of each adjustment rod 830 is the same, which is either clockwise or counterclockwise, and the central angle corresponding to the maximum swing amplitude of each adjustment rod 830 is 4°45′.

[0054] In order to further improve the accuracy of blood testing, in this embodiment, the axis of the cylinder corresponding to the swing amplitude of the adjusting rod 830 coincides with the axis of the cup body 1000 and the axis of the suspension wire 510, and the pushing assembly 400 rotates around the axis of the suspension wire 510 during the rotation process.

[0055] like Figures 1 to 3As shown, in one embodiment of the present invention, in order to improve the efficiency of taking and placing the cup body 1000 and avoid damage to the detection component 500 caused by manual taking and placing of the cup body 1000, a limiting device 600 and a clamping component 900 are further provided on the base 100. The limiting device 600 is used to conflict with the cup body 1000 and form a limit, and the clamping component 900 is used to clamp and fix the rocking arm 520 to improve the stability of the rocking arm 520 during the taking and placing process of the cup body 1000.

[0056] It is understandable that the cup body 1000 is separated from the rocking arm 520 by the limiting device 600 and the clamping assembly 900. Specifically, after the blood test is completed, the rocking arm 520 located above the cup body 1000 is first clamped and fixed by the clamping assembly 900. Secondly, the limiting device 600 and the top of the cup body 1000 are mutually abutted, and a vertical downward pressure is applied to the cup body 1000, while the driving device 200 moves downward synchronously, and drives the pushing assembly 400 to move downward, and separates the cup body 1000 from the rocking arm 520.

[0057] In addition, after the blood test is completed, the swing bar 520 located above the cup body 1000 can be first clamped and fixed by the clamping assembly 900. Then, the driving device 200 drives the pushing assembly 400 to move vertically downward, and the limiting device 600 contacts the top of the cup body 1000, and a vertical downward pressure is applied to the cup body 1000, and the cup body 1000 is separated from the swing bar 520.

[0058] like Figure 2 As shown, in this embodiment, a push rod 660 is provided on the side of the bottom of the limiting member 650 away from the support plate 720, the push rod 660 and the limiting member 650 are perpendicular to each other, the push rod 660 corresponds to the cup holder 430, and is located above the cup holder 430, and the orthographic projection of the push rod 660 on the cup holder 430 has a gap with the cup body 1000, and the push rod 660 is used to abut the cup holder 430. Specifically, the length of the push rod 660 is greater than the vertical distance from the side of the cup cover 1020 away from the cup holder 430 to the cup holder 430, and the length of the push rod 660 is less than the depth of the placement groove 431, so as to prevent the cup body 1000 from falling off the cup holder 430.

[0059] like Figure 1 , Figure 2 , Figure 3 and Fig.10As shown, in one embodiment of the present invention, the limiting device 600 includes a slide rail 610, a third motor 620 is provided on the top of the slide rail 610, a slide seat 630 is provided at the output end of the third motor 620, a slider 640 is provided on the side of the slide seat 630 close to the slide rail 610, and the slider 640 is movably mounted on the slide rail 610, and is used to drive the slider 640 to slide along the slide rail 610 through the slide seat 630 during the sliding process.

[0060] Among them, the third motor 620 is a screw motor, which is used to drive the slide 630 to move in a direction parallel to the slide rail 610 through the screw motor, and drive the slider 640 to slide along the slide rail 610 through the slide 630, and is used to improve the stability of the slide 630 during the sliding process through the cooperation between the slider 640 and the slide rail 610.

[0061] In addition, a stopper 650 is provided on one side of the slide 630 close to the push assembly 400. In the present invention, the shape of the stopper 650 is not specifically limited, and it can be any one of a stopper plate, a stopper 650 or a heterogeneous stopper structure, and can be specifically limited according to actual conditions. The stopper 650 is located above the push assembly 400. Specifically, the end of the stopper 650 is located above the push assembly 400, and there is a gap between the end of the stopper 650 and the rocking bar 520 to avoid contact between the stopper 650 and the rocking bar 520, thereby improving the accuracy of detection. The stopper 650 is used to form a limit with the cup body 1000.

[0062] After the blood test is completed, the rocking bar 520 spaced above the cup body 1000 is clamped and fixed by the clamping assembly 900, and the sliding seat 630 is driven by the third motor 620 to move in a direction close to the base 100. During the sliding process, the sliding seat 630 drives the limiting member 650 to move in a direction close to the cup body 1000, and makes the top rod 660 collide with the cup base 430. At the same time, the driving device 200 drives the pushing assembly 400 to move to the side away from the supporting plate 720, and makes the pushing assembly 400 move in a direction close to the base 100.

[0063] It should be noted that when the top rod 660 conflicts with the cup holder 430 and moves toward the side close to the base 100 at the same time, the cup cover 1020 remains stationary relative to the rocking arm 520, and when the stopper 650 gradually approaches the base 100, the cup body 1010 gradually moves away from the cup cover 1020. When the stopper 650 conflicts with the cup cover 1020, in the process of driving the stopper 650 to approach the base 100 by the third motor 620, the stopper 650 applies a pressure to the cup cover 1020 in the direction close to the base 100, and separates the cup cover 1020 from the rocking arm 520, at which time the cup cover 1020 returns to the initial state of contact with the cup body 1010. The stability of the rocking arm 520 is improved during the separation process of the cup body 1000 and the rocking arm 520, and the quality and efficiency of the separation of the cup body 1000 and the rocking arm 520 are improved.

[0064] like Figures 1 to 4 As shown, in one embodiment of the present invention, the clamping assembly 900 includes a first support platform 910 installed on the base 100. The shape of the first support platform 910 is not specifically limited, and the first support platform 910 is spaced apart from the pushing assembly 400 to prevent the first support platform 910 from affecting the lifting and lowering of the pushing assembly 400.

[0065] A second motor 920 is disposed on the top of the first support platform 910, and a clamping portion 930 is disposed at the output end of the second motor 920. The output end of the second motor 920 corresponds to the rocking arm 520, and the second motor 920 is used to drive the clamping portion 930 to clamp and fix the rocking arm 520. The clamping portion 930 is located above the limiter 650, and the clamping portion 930 is used to fix the rocking arm 520. It should be noted that the clamping portion 930 can be any one of a clamping claw and a clamping hand, and is used to fix the rocking arm 520.

[0066] like Figures 1 to 3 As shown, in one embodiment of the present invention, in order to improve the accuracy of blood detection, a code disc connecting ring and a code disc 530 are respectively mounted on the swing arm 520, and the code disc 530 is connected to the code disc connecting ring, and is used to fix the code disc 530 through the code disc connecting ring. An encoder 540 is provided at the bottom of the code disc 530, and the encoder 540 is used to detect the rotation angle of the code disc 530. The swing arm 520 is driven to rotate during the rotation of the cup body 1000, and the swing arm 520 drives the code disc 530 mounted on the swing arm 520 to rotate during the rotation. The encoder 540 detects the rotation angle of the code disc 530 and the suspension wire 510, which greatly improves the accuracy of blood detection.

[0067] like Figure 1 , Figure 2 and Figure 8 As shown, in one embodiment of the present invention, the pushing assembly 400 includes a cup holder 430 and a first base 410. The cup holder 430 is used to provide support for the cup body 1000. The first base 410 is used to push the cup holder 430 and can also push the cup body 1000 on the cup holder 430 out of the placement groove 431 to facilitate removing the cup body 1000 from the cup holder 430.

[0068] One side of the first base 410 is located on the connecting piece 300, and the other side of the first base 410 corresponds to the cup holder 430, and the cup holder 430 is located on the side of the first base 410 close to the rocking bar 520, and is used to make the cup body 1000 located in the placement groove 431 correspond to the rocking bar 520, by immersing the end of the rocking bar 520 in the blood in the cup body 1000, and detecting the blood in the cup body 1000.

[0069] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment of the present invention, a first groove 411 is provided on one side of the first base 410 close to the cup holder 430, and a first cavity 412 is further provided in the first base 410. The first cavity 412 is located below the first groove 411, and the first groove 411 is connected to the first cavity 412 through a first channel. One end of the first connecting rod 420 passes through the first cavity 412 and the first channel in sequence through the bottom of the first base 410, and the other end of the first connecting rod 420 forms a limit with one end of the connecting member 300.

[0070] In addition, the first connecting rod 420 is sleeved with a first connecting ring 421, and the first connecting rod 420 and the first connecting ring 421 are integrally formed to improve the stability of the first connecting ring 421 on the first connecting rod 420. The first connecting ring 421 is located in the first cavity 412, and the first connecting ring 421 is used to move in the first cavity 412.

[0071] The axis of the first connecting ring 421 coincides with the axis of the first connecting rod 420, and the first connecting ring 421 is used to form a limit with the first cavity 412. The first base 410 and the cup holder 430 correspond to each other, and the first base 410 pushes the cup holder 430 to move along the power direction of the driving device 200.

[0072] like Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.10As shown, in one embodiment of the present invention, the placement groove 431 is located on a side of the cup holder 430 close to the rocking bar 520, and the placement groove 431 is used to correspond to the rocking bar 520. The cup holder 430 is provided with a second cavity 432 and a bottom rod 440, the second cavity 432 is located below the placement groove 431, the second cavity 432 is connected to the placement groove 431 through a second channel, and the bottom rod 440 passes through the second cavity 432 and the second channel in sequence through the bottom of the cup holder 430, and extends into the placement groove 431.

[0073] Meanwhile, the bottom bar 440 is provided with a second connecting ring 441, which is integrally formed with the bottom bar 440 and is located in the second cavity 432. The second connecting ring 441 is used to move in the second cavity 432 and to form a limit with the second cavity 432 to prevent the bottom bar 440 from falling off the cup holder 430. The bottom bar 440 corresponds to the first connecting rod 420 and is used to form a limit with the first connecting rod 420 through the bottom bar 440.

[0074] Specifically, when the driving device 200 drives the connecting member 300 to move in the direction close to the rocking arm 520, the connecting member 300 conflicts with the bottom of the first connecting rod 420, applies a thrust to the first connecting rod 420, and pushes the first connecting rod 420 close to the rocking arm 520. When the first connecting rod 420 moves close to the rocking arm 520, it drives the first connecting ring 421 to move in the cavity close to the rocking arm 520. When the first connecting ring 421 conflicts with the top of the first cavity 412, it also drives the first base 410 to move in the direction close to the rocking arm 520. When the first base 410 conflicts with the cup holder 430, the first base 410 pushes the cup holder 430 to move toward the direction close to the rocking bar 520, and at the same time drives the cup body 1000 located in the placement groove 431 to move toward the direction close to the rocking bar 520, and inserts the end of the rocking bar 520 into the cup body 1010, and the blood in the cup body 1010 is detected by the detection component 500.

[0075] It should be noted that the number of the first bases 410 can be one, two, or any number above two, which can be specifically limited according to actual conditions. When the number of the first bases 410 is two or more, the adjacent first bases 410 are stacked in sequence, and the first groove 411 of any first base 410 corresponds to the rocking bar 520.

[0076] The adjusting rod 830 sequentially passes through the rotating base 820, the arc-shaped hole 721, the cup holder 430, and the first base 410, and is used to drive the adjusting rod 830 to swing along the arc-shaped hole 721 through the rotating base 820 when the rotating base 820 is driven by the first motor. During the swinging process, the adjusting rod 830 drives the cup holder 430 and the first base 410 to rotate synchronously along the swinging direction of the adjusting rod 830. During the rotation process, the cup holder 430 drives the cup body 1000 located in the placement groove 431 to rotate.

[0077] It should be noted that when the blood in the cup body 1010 has not yet begun to coagulate, the cup body 1010 is rotating while the cup cover 1020 is stationary relative to the positioning rod 710. During the detection process, when the blood gradually coagulates, the friction force of the blood on the protrusion 1021 set on the cup cover 1020 gradually increases, and gradually drives the protrusion 1021 to rotate, and at the same time drives the cup cover 1020 to rotate. While the cup cover 1020 rotates, it drives the rocking bar 520 connected to the cup cover 1020 to rotate. While the rocking bar 520 rotates, it drives the code disk 530 and the suspension wire 510 to rotate, and the encoder 540 detects the change in the rotation angle of the code disk 530, and the angle change detected by the encoder 540 is converted into a TEG elastic force diagram to improve the test stability.

[0078] In addition, the pushing components 400 are at least one group. It is understandable that the number of the pushing components 400 can be two groups or any number of groups above two groups, which can be specifically limited according to actual conditions.

[0079] When there are two groups of push assemblies 400, the two push assemblies 400 are spaced apart at both ends of the connector 300. When there are multiple groups of push assemblies 400, the multiple groups of push assemblies 400 are spaced apart, and each group of push assemblies 400 is correspondingly located above the connector 300, so as to push the multiple groups of push assemblies 400 to move synchronously through the connector 300.

[0080] The number of the push components 400 is the same as the number of the detection components 500, the number of the limit devices 600, the number of the clamping components 900, and the number of the power mechanism 800, and one group of push components 400 corresponds to one group of detection components 500, one group of limit devices 600, one group of clamping components 900, and one group of power mechanism 800. The specific number of the push components 400 can be determined according to actual conditions, and can be used to synchronously detect the same blood, obtain multiple groups of detection data, and compare the multiple groups of detection data to further improve the accuracy of the detection and improve the detection efficiency.

[0081] like Figure 6 , Fig. 9 and Fig.10As shown, in one embodiment of the present invention, a reset spring is provided in the second cavity 432 , and the reset spring is located on the side of the second connecting ring 441 away from the connecting member 300 , and is used to reset the bottom rod 440 and the second connecting ring 441 through the reset spring.

[0082] In addition, a return spring is also provided in the first cavity 412 . The return spring is located at a side of the first connecting ring 421 away from the connecting member 300 , and is used to return the first connecting rod 420 and the first connecting ring 421 to their original positions.

[0083] It should be noted that, after the detection is completed, the driving device 200 drives the pushing assembly 400 to move to the side away from the support plate 720, and makes the pushing assembly 400 move in the direction close to the base 100. It should be noted that when the push rod 660 conflicts with the cup holder 430 and moves to the side close to the base 100 at the same time, the cup cover 1020 remains stationary relative to the rocking bar, and when the stopper 650 gradually approaches the base 100, the cup body 1010 gradually moves away from the cup cover 1020. When the stopper 650 conflicts with the cup cover 1020, in the process of driving the stopper 650 to approach the base 100 by the third motor 620, the stopper 650 applies a pressure to the cup cover 1020 in the direction close to the base 100, and separates the cup cover 1020 from the rocking bar 520, and at this time, the cup cover 1020 returns to the initial state of contact with the cup body 1010. The stability of the rocking arm 520 during the separation process of the cup body 1000 and the rocking arm 520 is improved, and the separation quality and separation efficiency of the cup body 1000 and the rocking arm 520 are improved.

[0084] When the driving device 200 is stationary and the third motor 620 drives the stopper 650 to move toward the base 100, the connecting member lifts up 420, and 420 moves toward the cup holder 430. During the movement of 420, the stopper 650 contacts the bottom rod 440, and drives the bottom rod 440 to move toward the support plate 720. During the movement of the bottom rod 440, the cup body 1000 is ejected from the placement groove 431. During the movement of the cup body 1000 toward the support plate 720, the stopper 650 contacts the stopper 650, and the stopper 650 and the cup body 1000 form a limit, so that the cup body 1000 is prevented from falling from the cup holder, and the stability of the cup body 1000 on the cup holder 430 is improved. At this time, the stopper 650 is driven away from the cup holder 430 by the third motor 620, so that the cup body 1000 is easily removed from the cup holder 430, and the efficiency of taking and placing the cup body 1000 is improved.

[0085] Furthermore, in order to improve the accuracy of the detection of blood during the coagulation process, a temperature control element is provided on the inner wall of the placement groove 431 and / or the bottom of the placement groove 431. It can be understood that a temperature control element is provided on the inner wall of the placement groove 431 or the bottom of the placement groove 431. Or a temperature control element is provided on the inner wall of the placement groove 431 and the bottom of the placement groove 431. The temperature of the blood in the cup body 1010 is adjusted by the temperature control element, and the blood is kept at a constant temperature during the coagulation process, so as to avoid the influence of temperature changes on the blood detection results and improve the accuracy of the detection data.
