Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment, and in particular to a blood coagulation analyzer reaction cup loading device. Background Technology

[0002] A blood coagulation analyzer is a core automated testing device in the field of clinical laboratory testing. It is mainly used to analyze human blood coagulation, fibrinolytic system function and related coagulation factor activity, providing key data support for the diagnosis, treatment monitoring and preoperative coagulation function assessment of hemorrhagic diseases (such as hemophilia) and thrombotic diseases (such as myocardial infarction and cerebral infarction).

[0003] Among them, the reaction cup of the blood coagulation analyzer (also known as the blood coagulation cup or coagulation reaction cup) is the core consumable that carries blood samples and reagents and causes coagulation reaction during the blood coagulation test. Its material, structure, size and performance directly affect the accuracy, repeatability and instrument operation stability of the test results, and it is an indispensable key component in the blood coagulation analyzer's supporting consumables.

[0004] However, the reaction cup storage compartment design of automated blood coagulation analyzers usually has a clear capacity limit. The number of reaction cups that can be loaded at one time is generally concentrated in the range of 300-600, which is equivalent to the testing volume of 40-90 clinical samples. This cannot meet the needs of large hospitals for continuous testing of large sample volumes (more than 100).

[0005] The core reason for this design constraint is the mechanical operation characteristics of the cup sorting mechanism: the automatic cup sorting function of the blood coagulation analyzer relies on precision transmission components (such as gears, push rails, and sorting mechanisms) to achieve the orderly arrangement, separation, and transportation of reaction cups. If too many reaction cups are loaded at once, the cups will be stacked and squeezed in the chamber, resulting in a messy posture. This will not only increase the resistance of the mechanical transmission, but may also cause the cups to get stuck at the rail interface, sorting channel, or push component, thereby interrupting the testing process.

[0006] Meanwhile, excessive compression of the reaction cups may cause deformation or damage, affecting the sealing and accuracy of subsequent tests. In addition, the capacity of the chambers must match the overall size design of the instrument. Blindly expanding the chambers may increase the instrument's footprint, reduce portability, and hinder the precise control and maintenance of the cup handling mechanism. Utility Model Content

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0042] Combination Figures 1 to 4 This embodiment proposes a blood coagulation analyzer reaction cup loading device, comprising:

[0043] Cover 10;

[0044] The cylinder 20 has an opening at both the top and bottom; the top of the cylinder 20 and the cover 10 are detachably connected; the cylinder 20 includes a cylindrical body 201 and a plurality of partition plates 202 provided inside the body 201; a cavity for storing the blood coagulation analyzer reaction cup is formed between two adjacent partition plates 202.

[0045] The drive source 30 is located at the top of the cover 10;

[0046] The rotating actuator 40 includes a rotating shaft 401 connected to the drive source 30 and a turntable 402 connected to the rotating shaft 401; the turntable 402 has a material discharge channel; wherein, a plurality of partition plates 202 are arranged around the rotating shaft 401 in the circumferential direction.

[0047] The discharge hopper 50 is located at the bottom of the cylinder 20.

[0048] This embodiment provides a blood coagulation analyzer reaction cup loading device. The top and bottom of the cylindrical body 20 are open, and multiple partition plates 202 are provided inside the cylindrical body 20. Specifically, the multiple partition plates 202 are arranged circumferentially around the rotating shaft 401, meaning that the partition plates 202 are arranged radially around the rotating shaft 401 to form a storage space. The number of partition plates can be four, five, or seven, and the arrangement can be equidistant or unequal, for example, adjusted according to the size of the reaction cup and storage requirements.

[0049] The material discharge channel is an opening that allows the reaction cup to pass through. In practical applications, it can be designed as a circle, ellipse, fan shape or rectangle, and its size can be adapted to reaction cups of different specifications.

[0050] The top of the cover 10 and the cylinder 20 are detachably connected. The connection method may include threaded connection, snap-fit ​​connection, magnetic connection or quick clamping mechanism, which is used to realize the loading operation of the reaction cup.

[0051] The drive source 30 is located on the top of the cover 10 and can be a stepper motor, DC motor or other rotary power device to provide rotational power.

[0052] The hopper 50 is located at the bottom of the cylinder 20 and can be designed as a cone, funnel, or straight cylinder to guide the reaction cup into the subsequent mechanism.

[0053] Therefore, the cavity formed by the partition plate 202 stores a single reaction cup, avoiding stacking and compression. Combined with the material discharge channel of the turntable 402 and the circumferential layout of the partition plate 202, when the drive source 30 drives the rotating shaft 401 to rotate, the material discharge channel is aligned with each cavity in sequence, realizing the orderly discharge of reaction cups one by one. This solves the problem of limited storage capacity of blood coagulation analyzer reaction cups, which can easily lead to jamming and damage, and meets the long-term consumable supply needs of large-scale continuous testing scenarios.

[0054] The overall operation of the blood coagulation analyzer reaction cup loading device is based on a rotary compartmentalized storage and orderly feeding mechanism to achieve a stable and continuous supply of reaction cups.

[0055] Combination Figures 6 to 8 In this embodiment, it is further proposed that there are six partition plates 202; the six partition plates 202 are arranged at equal intervals around the rotating shaft 401.

[0056] Specifically, the partition plate 202 refers to the structural component used to divide and form the storage chamber of the blood coagulation analyzer reaction cup within the cylinder 20. The number is limited to six to ensure that a fixed number of storage chambers are formed within the cylinder 20. The arrangement of the six partition plates 202 at equal intervals around the rotating shaft 401 can be understood as the partition plates 202 being evenly distributed around the rotating shaft 401, so that the angular interval between adjacent partition plates 202 is equal. The purpose is to eliminate the deviation in the position of the chambers caused by uncertainty in the number or arrangement.

[0057] Specifically, this embodiment limits the number of partition plates 202 to six and arranges them at equal intervals, so that the six storage cavities formed within the cylinder 20 are evenly distributed around the rotating shaft 401. The turntable 402 of the rotating actuator 40 is configured to rotate at a fixed angle each time, thereby ensuring that the material discharge channel is precisely aligned with any cavity. When the drive source 30 drives the rotating shaft 401 to rotate, the turntable 402 rotates synchronously, allowing the reaction cups in the cavities to smoothly fall into the discharge hopper 50 through the material discharge channel. This avoids the problem of reaction cups getting stuck at the edge of the partition plate 202 or falling poorly due to angular deviations, ensuring the continuity and stability of the reaction cup supply process.

[0058] Combination Figure 9In this embodiment, the shape of the material discharge channel is the same as the shape of the cavity formed by the two adjacent partition plates 202; the size of the material discharge channel is the same as the size of the cavity formed by the two adjacent partition plates 202.

[0059] The shape of the material discharge channel refers to the opening contour on the turntable 402 through which the reaction cup passes. It can be implemented using geometric shapes such as fan, rectangle or polygon. The purpose is to ensure that the reaction cup does not undergo abrupt changes in geometric contour during the transfer process, thereby maintaining its original posture. The size of the material discharge channel refers to the dimensional parameters of the channel. It can be implemented based on the actual size of the cavity through precision machining or mold forming. The purpose is to eliminate gap problems caused by inconsistent dimensions and prevent the reaction cup from shaking due to looseness or being compressed due to excessive tightness during material discharge.

[0060] Specifically, the solution in this embodiment makes the geometric characteristics of the material discharge channel perfectly match the storage cavity. When the turntable 402 rotates to a specific position under the drive of the drive source 30, the cavity formed by the adjacent partition plates 202 is precisely aligned with the material discharge channel. The reaction cup slides directly from the cavity into the material discharge channel under the action of gravity without the need for posture adjustment. This avoids tilting, jamming or squeezing caused by differences in shape or size, and ensures that the reaction cup is transferred to the material discharge hopper 50 in a stable and continuous manner.

[0061] Combination Figure 3 This embodiment further proposes that the output end of the drive source 30 and the center of the rotating shaft 401 are on the same axis.

[0062] The alignment of the output end of the drive source 30 and the center of the rotating shaft 401 means ensuring that there is no offset in the power transmission path. This can be achieved by using a high-precision coupling, direct coupling, or precision-machined mounting base. The purpose is to eliminate the extra torque and vibration caused by shaft misalignment, thereby ensuring the stability of the rotating system.

[0063] Specifically, the solution in this embodiment ensures the directness and accuracy of power transmission by strictly aligning the output end of the drive source 30 with the center axis of the rotating shaft 401, eliminating the eccentric effect during rotation, so that the turntable 402 remains highly stable when rotating, and the cavity formed by the adjacent partition plates 202 can accurately guide the reaction cup to slide along the predetermined path to the discharge hopper 50, avoiding the reaction cup posture confusion or conveying interruption caused by vibration.

[0064] This embodiment further proposes that the drive source 30 is a servo motor.

[0065] Among them, the drive source 30 refers to the device used to provide rotational power and achieve precise position control. It can be implemented by a DC servo motor, an AC servo motor or a stepper servo motor. Its purpose is to provide the rotating actuator 40 with high-precision angle control capability during rotation, thereby effectively avoiding mechanical failures caused by positioning errors.

[0066] Specifically, the solution in this embodiment uses a closed-loop control system of a servo motor to precisely control the rotation angle and stop position of the rotating shaft 401, so that the material discharge channel of the turntable 402 is strictly aligned with the cavity formed by the adjacent partition plate 202 after each rotation; the servo motor receives position feedback signals in real time and dynamically adjusts the drive parameters to ensure that there is no cumulative error during the rotation of the turntable 402, thereby ensuring that the reaction cup can smoothly pass through the material discharge channel into the discharge hopper 50 and avoid jamming caused by misalignment.

[0067] Combination Figure 1 and Figure 2 This embodiment further proposes to include a sensing element 60 located near the discharge port of the hopper 50 and connected to the drive source 30; the sensing element 60 is configured to detect the number of reaction cups in the hopper 50 in real time.

[0068] The sensing element 60 is a sensor used to detect the passage of the reaction cup. It can be implemented using a photoelectric sensor or an ultrasonic sensor, with the aim of accurately capturing the physical presence signal of the reaction cup. Positioning the sensing element 60 near the discharge port of the hopper 50 means placing it in the vicinity of the discharge port. It can be fixed to the side wall of the discharge port or suspended above the discharge path using a bracket. This ensures that the reaction cup passes through the sensing area during output, avoiding detection omissions caused by the stacking posture within the cylinder 20. Connection to the drive source 30 means that the sensing element 60 establishes a signal interaction path with the control unit of the drive source 30. This can be achieved through a wired interface or a wireless communication module, with the aim of synchronously acquiring the rotation timing of the turntable 402 to coordinate the detection triggering timing.

[0069] Specifically, the solution in this embodiment precisely positions the sensing element 60 at the discharge port of the hopper 50, ensuring that each reaction cup passes through the sensing area during the output process, thus enabling reliable identification. After the sensing element 60 is connected to the drive source 30, it can accurately trigger the counting logic when the turntable 402 performs a rotation action based on the rotation state information of the drive source 30, effectively distinguishing the passing events of individual reaction cups. The real-time detection function continuously collects and processes the sensing signals, dynamically calculates the amount of reaction cups in the hopper 50, and immediately generates an early warning command when the quantity drops to a preset threshold, ensuring that the system responds promptly to the need for consumable replenishment.

[0070] In one specific implementation, the sensing element 60 is a through-beam photoelectric sensor, with its transmitting end and receiving end installed on opposite sides of the discharge port of the hopper 50. When the reaction cup passes through, it blocks the light beam and generates a level change signal. The sensor is connected to the servo drive circuit of the drive source 30 through a shielded wire. When the rotating shaft 401 rotates by an interval angle of the partition plate 202, the servo drive circuit updates the reaction cup count according to the pulse signal output by the sensor.

[0071] Through the above solution, this embodiment realizes continuous dynamic monitoring of the number of reaction cups within the hopper 50, and can proactively warn before the reaction cups are about to run out, effectively preventing the interruption of the testing process due to the shortage of consumables, and ensuring the stable operation of the blood coagulation analyzer in large-scale testing scenarios.

[0072] Combination Figure 3 In this embodiment, it is further proposed that the inner diameter of the end of the hopper 50 connected to the bottom of the cylinder 20 is the same as the inner diameter of the cylinder 20; the inner diameter of the end of the hopper 50 away from the bottom of the cylinder 20 is smaller than the inner diameter of the cylinder 20.

[0073] In practical applications, the inner diameter of the end where the hopper 50 and the bottom of the cylinder 20 are connected refers to the internal diameter at the interface between the hopper 50 and the cylinder 20. It can be achieved by using machining tolerance control that is completely consistent with the inner diameter of the cylinder 20. The purpose is to eliminate the abrupt change in size in the transition area and avoid the reaction cup from being squeezed or stuck due to the step effect. The inner diameter of the end of the hopper 50 away from the bottom of the cylinder 20 refers to the internal diameter at the outlet end of the hopper 50. It can be achieved by using a conical or stepped tapered structure. The purpose is to guide the cup to naturally converge based on the dynamic characteristics of the falling reaction cup, maintaining an orderly arrangement and stable posture.

[0074] Specifically, the solution in this embodiment ensures that the inner diameter of the end of the hopper 50 connected to the bottom of the cylinder 20 is strictly matched with the inner diameter of the cylinder 20, so that there is no size difference when the reaction cup transitions from the cylinder 20 to the hopper 50, thereby avoiding the cup from shifting its posture at the connection point. At the same time, the inner diameter of the end of the hopper 50 away from the bottom of the cylinder 20 is smaller than the inner diameter of the cylinder 20, forming a tapered channel. This channel generates a radial constraint force during the fall of the reaction cup, effectively guiding the cup to move stably along the axial direction and preventing scattered accumulation. The two work together to ensure the reliability of continuous feeding.

[0075] This embodiment further proposes a top threaded connection between the cover 10 and the cylinder 20.

[0076] Among them, the threaded connection refers to the mechanical connection structure formed by the helix. It can be achieved by the interlocking of external and internal threads. The purpose is to provide a progressive axial clamping force to ensure that the cover 10 and the cylinder 20 maintain a stable connection under vibration conditions and avoid sealing failure due to loose connection. This connection method can also adopt left-hand or right-hand thread structure to adapt to different operating habits. Its core function is to balance the reliability of connection and the convenience of operation, and to provide basic protection for the reaction cup storage environment.

[0077] As a preferred embodiment, the solution of this embodiment is implemented as follows: the bottom edge of the cover 10 is provided with a standard external thread structure, and the top opening of the cylinder 20 is provided with a matching internal thread structure; during the installation process, the user rotates the cover 10 to make the external thread and the internal thread engage axially until the preset locking position is reached. At this time, the cover 10 and the cylinder 20 form a tight connection without gaps, and their contact surface can naturally form an annular sealing band, effectively blocking the influence of the external environment on the internal cavity of the cylinder 20.

[0078] Through the above solution, this embodiment effectively prevents the cover 10 from accidentally loosening due to vibration or operation during continuous operation of the blood coagulation analyzer, avoids the risk of contamination caused by exposure of the reaction cup, simplifies the opening and closing process when replenishing the reaction cup, improves the device maintenance efficiency, and ensures the sealing reliability of the reaction cup storage environment and the accuracy of the test data during the blood coagulation test.

[0079] Combination Figure 1 and Figure 2 In this embodiment, four handles 101 are provided on the top of the cover 10; the four handles 101 are arranged at equal intervals around the drive source 30 with the drive source 30 as the center.

[0080] In practical applications, the handle 101 refers to the operating component that the user grips. It can be implemented by using an arc-shaped handle, a straight handle, or a raised structure with anti-slip texture on the surface. Its purpose is to provide a clear gripping point and avoid the risk of slippage caused by the smooth surface of the cover 10. The evenly spaced arrangement can be understood as the handles 101 being evenly distributed around the center of the drive source 30. Its purpose is to ensure that the force points can be evenly distributed when the user rotates the operation, preventing the cover 10 from tilting or getting stuck.

[0081] Specifically, the solution in this embodiment arranges four handles 101 at equal intervals around the drive source 30 on the top of the cover 10, so that when the user grips the handles 101 to perform rotation, the force points are symmetrically distributed around the rotation center, thereby effectively dispersing the operating force, avoiding local stress concentration, achieving smooth rotation of the cover 10, and reducing slippage and unevenness during operation.

[0082] As a specific implementation method, the solution of this embodiment is implemented as follows: the four handles are distributed in a cross shape with the drive source 30 as the center, which makes it convenient for the operator to grip with both hands or multiple fingers of one hand, and the surface of the handles is provided with fine concave and convex textures to enhance friction.

[0083] Through the above solution, this embodiment significantly improves the convenience and stability of rotating the cover 10 in the daily use of the blood coagulation analyzer reaction cup loading device, reduces the risk of device wear and detection interruption caused by slippage during operation, and is especially suitable for the frequent operation requirements in continuous detection scenarios.

[0084] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
