Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and particularly relates to a reaction cup supply device and a coagulation analyzer. Background Art

[0002] The reaction cup supply device is an important component of a fully automatic coagulation analyzer. During the operation of a fully automatic coagulation analyzer, the automatic transmission of reaction cups is a necessary condition for realizing a fully automatic coagulation analyzer.

[0003] The reaction cup is grabbed by a gripper. The gripper is provided with a detection part for detecting whether the reaction cup has moved to a preset position and grabbing the reaction cup located at the preset position. The detection part detects through an opposed photoelectric coupler. Since the reaction cup has a very high transparency, it may cause the gripper to grab nothing or misgrab, and even damage the reaction cup. In addition, fixing the photoelectric coupler at the gripper requires high machining precision and assembly precision of parts and high costs.

[0004] Therefore, how to provide a reaction cup supply device that can ensure the grabbing accuracy, avoid damage to the reaction cup caused by grabbing nothing or misgrabbing, and at the same time reduce the machining and installation precision and requirements and reduce costs is a technical problem that those skilled in the art urgently need to solve.

That is to say, after the gripper places the grabbed reaction cup at the required position, it directly returns to the cup-grabbing position. When the detection part at this cup-grabbing position detects that a reaction cup passes by, it can directly perform the next grabbing.

[0036] In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The embodiment of the present application provides a reaction cup supply device and a coagulation analyzer. Among them, the coagulation analyzer includes a reaction cup supply device, and also includes a gripper 7, a cup selection device, a cup selection guide rail 9, a buffer device 10, etc.

[0038] As Figure 1 shown, the reaction cup supply device includes a base 1, a runner 2, a driving part 4, and a detection part 3. Among them, the runner 2 is rotatably arranged on the base 1, the driving part 4 is used to drive the runner 2 to rotate, and a plurality of placement positions 21 are arranged at intervals along the circumference of the runner 2. The placement position 21 is used to place the reaction cup 5. The base 1 is also provided with a cup gripping position 11 along the circumference of the runner 2, and a detection part 3 is also provided at the cup gripping position 11. The detection part 3 is used to detect whether there is a reaction cup 5 reaching the cup gripping position 11. The gripper 7 is used to grip the reaction cup 5 located at the cup gripping position 11 and move the reaction cup 5 to the required position (which can be the buffer device 10 as Figure 4 shown).

[0039] That is to say, in this embodiment, the base 1 is provided with a cup gripping position 11 and a detection part 3. The detection part 3 is used to detect whether there is a reaction cup 5 reaching the cup gripping position 11. The gripper 7 is used to grip the reaction cup 5 that reaches the cup gripping position 11. That is to say, after the gripper 7 places the gripped reaction cup 5 at the required position, it directly returns to the cup gripping position 11. When the detection part 3 at the cup gripping position 11 detects that a reaction cup 5 passes by, it can directly perform the next gripping. And because the detection part 3 is arranged on the base 1, the detection part 3 does not need to move with the gripper 7, avoiding the situation that the detection accuracy is affected due to position changes. Therefore, the reaction cup supply device provided in this embodiment can ensure the detection accuracy of the detection part 3, ensure the accuracy of the detection result, and avoid the situation of mis-gripping.

[0040] Moreover, since the gripper 7 does not need to be provided with a detection part 3 and only needs to perform the grasping and placing operations of the reaction cup 5 at a specified position, the structure of the gripper 7 can be simplified, which is convenient for the movement of the gripper 7. At the same time, the processing accuracy, assembly accuracy, and difficulty requirements of each part are relatively low, so that the cost can be reduced.

[0041] In this embodiment, the specific number of the cup gripping positions 11 is not limited, and it is preferably at least two, specifically two, three (as Figure 4As shown in the figure), two or more can be provided, and each cup-gripping position 11 is arranged along the circumferential direction of the rotating wheel 2. The number of grippers 7 is the same as the number of cup-gripping positions 11, and each gripper 7 is used to grip the reaction cup 5 from the corresponding cup-gripping position 11 to ensure the gripping accuracy. With such a setting, compared with the solution with only one cup-gripping position 11, the cup-gripping efficiency can be effectively improved, the supply efficiency of the reaction cup 5 can be improved, and thus the analysis speed of the analyzer can be increased.

[0042] Furthermore, in this embodiment, the number of placement positions 21 is not limited. As Figure 2 shown, the base 1 has seven placement positions 21, and these seven placement positions 21 are evenly spaced along the circumferential direction of the rotating wheel 2. When the number of cup-gripping positions 11 is three, the distance between adjacent two cup-gripping positions is the same as the distance between adjacent two placement positions 21, ensuring that the grippers 7 corresponding to the three cup-gripping positions 11 can perform the gripping operation simultaneously.

[0043] As Figure 3 and Figure 5 shown, the upper surface of the rotating wheel 2 and the base 1 are respectively provided with mutually adapted indicating parts to ensure the installation accuracy of the rotating wheel 2 and the base 1. The specific structure of the indicating parts is not limited. For example, the end face of the groove wall of the installation groove 13 of the base 1 is provided with a pointer, the rotating wheel 2 is provided with a scale line 22, or the rotating wheel 2 is provided with a pointer, the end face of the groove wall of the installation groove 13 of the base 1 is provided with a scale line 22, or both are respectively provided with scale lines 22.

[0044] The material of the rotating wheel 2 is preferably polyoxymethylene, which can protect the appearance of the reaction cup 5 and will not wear the reaction cup 5 at the same time.

[0045] As Figure 1 shown, the reaction cup supply device further includes a driving part 4 for driving the rotating wheel 2 to rotate. Specifically, the driving part 4 includes a motor 41, a driving wheel 42, a driven wheel 43 and a rotating shaft 44. The motor 41 drives the driving wheel 42 to rotate, and the driving wheel 42 and the driven wheel 43 are driven by a synchronous belt 45. The rotating shaft 44 is fixedly arranged coaxially with the rotating wheel 2. The belt pulley drive structure is compact and has high efficiency. When the number of placement positions 21 is seven, the transmission ratio between the driving wheel 42 and the driven wheel 43 is 1:7. For example, the driving wheel 42 uses a synchronous belt wheel with 15 teeth, and the driven wheel 43 uses 105 teeth to ensure the accuracy of each position.

[0046] As Figure 2 and Figure 3 shown, the detection part 3 includes an operating part 31, an elastic restoring part 32 and a triggering part 33. Among them, the operating part 31 is rotatably arranged on the base 1, and the elastic restoring part 32 and the triggering part 33 are both fixedly arranged on the base 1. The reaction cup 5 rotated to the cup-gripping position 11 can abut against the operating part 31, so that the operating part 31 rotates relative to the base 1 and triggers the triggering part 33 (as Figure 2As shown in the figure, the elastic restoring member 32 can act on the actuating member 31 to rotate it in the reverse direction to reset and disengage from the triggering member 33 (as Figure 3 shown).

[0047] It is not difficult to understand that when a reaction cup 5 passes through the cup-gripping position 11, the reaction cup 5 can trigger the triggering member 33 through the actuating member 31, and the gripper 7 can directly grip the reaction cup 5 located at the cup-gripping position 11. When the reaction cup 5 is gripped and lifted by the gripper 7 or the runner 2 rotates to drive the reaction cup 5 away from the cup-gripping position 11, the acting force of the reaction cup 5 on the actuating rod is released. At this time, the actuating member 31 can be reset under the action of the elastic restoring member 32 and disengage from the triggering member 33. Specifically, in this embodiment, the elastic restoring member 32 is preferably a spring. When the triggering member 33 is triggered by the actuating member 31, the spring can be in a stretched state or in a compressed state as Figure 2 shown, and no specific limitation is made here.

[0048] Moreover, in this embodiment, no specific limitation is made on the specific structure of the actuating member 31. For example, it can be an actuating rod, an actuating block or an actuating slat.

[0049] Similarly, no specific limitation is made on the specific structure of the triggering member 33. In this embodiment, the triggering member 33 is preferably a grooved optocoupler. The reaction cup 5 rotating to the cup-gripping position 11 can push the actuating member 31 to rotate, and part of the actuating member 31 can enter the groove structure of the grooved optocoupler, so that the grooved optocoupler is triggered. The spring can act on the actuating member 31 to move it in the reverse direction and disengage from the groove structure of the grooved optocoupler.

[0050] The height of the reaction cup 5 should be higher than the thickness of the runner 2, so that the bottom of the reaction cup 5 extends out of the lower surface of the runner 2. The actuating member 31 is located below the runner 2. After the reaction cup 5 reaches the cup-gripping position 11, the part of the bottom of the reaction cup 5 extending out of the lower surface of the runner 2 can act on the actuating member 31, so that the actuating member 31 rotates relative to the base 1.

[0051] Of course, it can also be that the top of the reaction cup 5 extends out of the upper surface of the runner 2, the actuating member 31 is located above the runner 2. After the reaction cup 5 reaches the cup-gripping position 11, the part of the top of the reaction cup 5 extending out of the upper surface of the runner 2 can act on the actuating member 31, so that the actuating member 31 rotates relative to the base 1.

[0052] With such a setting, it can be ensured that the reaction cup 5 reaching the cup-gripping position 11 can fully act on the actuating member 31, ensuring that the actuating member 31 can rotate and trigger the triggering member 33, thereby ensuring the detection sensitivity and accuracy of the detection unit 3.

[0053] Such as Figure 2 and Figure 3As shown, a plurality of notches are provided along the circumference of the outer edge of the runner 2, and each notch forms a placement position 21. The top edge of the reaction cup 5 placed in the notch can protrude from the upper surface of the runner 2, and the reaction cup 5 can enter and exit the placement position 21 through the opening of the notch.

[0054] The coagulation analyzer further includes a cup selection device. The base 1 is further provided with a cup delivery position 12. The cup selection device is used to place the reaction cup 5 in the placement position 21 through the cup delivery position 12. Specifically, at the cup delivery position 12, the cup selection device continuously delivers the reaction cup 5 to the runner 2. Only when the runner 2 rotates to an empty placement position 21 located at the cup delivery position 12, the reaction cup 5 can enter the placement position 21 through the opening of the notch, with a simple structure and convenient operation. Specifically, the cup selection device feeds the reaction cup 5 from the cup delivery position 12 to the placement position 21 through the cup selection guide rail 9.

[0055] Of course, it is also possible that a plurality of hole structures are circumferentially spaced on the runner 2, and each hole structure forms a placement position 21. When the placement position 21 is formed through the notch, the reaction cup 5 can enter and exit through the opening of the notch, facilitating the picking and placing operation of the reaction cup 5 and simplifying the operation requirements of the gripper 7 and the cup selection device.

[0056] Preferably, a guiding surface is further provided between the inner wall surface of the notch and the outer peripheral wall surface of the runner 2. The guiding surface can be an arc surface or a flat surface structure, and no specific limitation is made here. The setting of the guiding surface facilitates the cup delivery operation and can also prevent the reaction cup 5 from being damaged by the edges and corners.

[0057] The reaction cup supply device further includes a mating portion 6 provided on the base 1, such as Figure 6 As shown, the upper surface of the mating portion 6 includes a first region 61 and a second region 62. When the mating portion 6 is fixed to the base 1, the height of the first region 61 is less than the height of the second region 62. Among them, the first region 61 is provided on one side of the cup delivery position 12, and the second region 62 is provided on one side of the cup grasping position 11. The runner 2 can drive the reaction cup 5 to move so that the bottom of the reaction cup 5 slides along the upper surface of the mating portion 6.

[0058] Specifically, at the cup delivery position 12, the height of the first region 61 is relatively low, and the height of the reaction cup 5 located here is relatively low. The top rim of the reaction cup 5 fits or is close to the upper surface of the runner 2. By rotating the runner 2 at a preset angle, an empty placement position 21 reaches the cup delivery position 12, and the reaction cup 5 randomly falls into the cup selection guide rail 9 by the cup selection device. Then, as Figure 5 As shown, the reaction cup 5 moves along the cup selection guide rail 9 to the cup delivery position 12, that is, the junction of the cup selection guide rail 9 and the runner 2. The top rim of the reaction cup 5 falls along the upper surface of the cup selection guide rail 9 and enters the placement position 21 through the opening of the notch.

[0059] The top rim of the reaction cup 5 moves along the upper surface of the cup selection guide rail 9. When entering the placement position 21 from the cup delivery position 12, the top rim of the reaction cup 5 is in contact with the upper surface of the rotating wheel 2. In this way, it can be avoided that the reaction cup 5 is damaged due to the height difference during the process from the cup selection guide rail 9 to the rotating wheel 2.

[0060] At the cup grasping position 11, the height of the second region 62 is relatively high, and the height of the reaction cup 5 located here is relatively low. Moreover, the top of the reaction cup 5 extends a certain height above the upper surface of the rotating wheel 2, and the gripper 7 can move it by grasping the top rim of the reaction cup 5, which is relatively convenient to operate. In this embodiment, the height of the top of the reaction cup 5 extending above the upper surface of the rotating wheel 2 is not specifically limited.

[0061] The specific structure of the gripper 7 is not limited, as long as the gripper 7 can grasp the top rim of the reaction cup 5.

[0062] In this embodiment, the specific structure of the mating part 6 is not limited. As Figure 6 shown, the transition between the first region 61 and the second region 62 is smooth. Specifically, it can be achieved through an inclined surface or an arc surface, ensuring that the bottom of the reaction cup 5 can smoothly slide along with the rotation of the rotating wheel 2 while being driven by the mating part 6. In addition, the mating part 6 is fixed to the base 1, and the specific fixing method between the two is not limited. For example, it can be set as an integral structure, fixed by fasteners, or fixed by welding, bonding, etc.

[0063] As Figure 1 shown, an installation groove 13 is further provided at the top of the base 1. The mating part 6 and the rotating wheel 2 are both installed in the installation groove 13, and the detection part 3 is arranged on the groove wall of the installation groove 13. In this way, the structural stability can be ensured, and protection can be provided for the rotating wheel 2, the mating part 6, and the detection part 3. An installation notch 14 is also provided on the groove wall of the installation groove 13. The installation notch 14 forms the cup delivery position 12, and the reaction cup 5 can enter the installation groove 13 through the installation notch 14, and then enter the notch through the opening, and then reach the placement position 21.

[0064] As Figure 1 shown, the reaction cup supply device further includes a bracket 8. The base 1 and the driving part 4 are both arranged on the bracket 8. Among them, the motor 41 can be arranged at the bottom of the bracket 8, which is convenient for the overall structural layout.

[0065] The above is only the preferred embodiment of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
