[0001] Cross-references to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411997393.8, filed with the Chinese Patent Office on December 31, 2024, entitled "Cup-feeding device structure, feeding device and diagnostic equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of automated in vitro diagnostic equipment technology, specifically to the cup-feeding device structure, the feeding device, and the diagnostic equipment. Background Technology

[0004] During the use of diagnostic equipment, reaction cups are typically moved back and forth using a chain-type automatic feeding device, which includes steps such as feeding, arranging, and separating.

[0005] However, existing chain-type automatic feeding devices are prone to problems such as cup jamming and horizontal cup movement during the feeding and sorting process, resulting in a high failure rate and poor reliability. Summary of the Invention

[0006] In view of this, this application provides a cup-sorting structure for a feeding device, a feeding device, and a diagnostic device to solve the problems of existing chain-type automatic feeding devices that are prone to cup jamming, horizontal cup movement, etc., resulting in a high failure rate and poor reliability.

[0007] In a first aspect, this application provides a cup-sorting structure for a feeding device, comprising:

[0008] The receiving channel has a feed inlet at the top;

[0009] A movable component, located within the accommodating channel, is movable along its vertical direction and is used to support the reaction cup;

[0010] The base and the drive component are provided. The base is located at the lower end of the receiving channel, and the drive component is located on the base. The moving component is connected to the drive component through a connector. The drive component is used to drive the moving component to move up and down along the receiving channel.

[0011] Beneficial effects: The feeding device of this application has a cup-sorting structure. The reaction cup enters the receiving channel from the feed port of the receiving channel. At the same time, the driving component drives the moving assembly to rise to the highest position to receive the reaction cup. Then, the driving component drives the moving assembly and the reaction cup to descend. During the descent, the reaction cup collides with the inner wall of the receiving channel and flips and corrects itself under the influence of gravity, so that its open end is facing upward and stays in the moving assembly. When the driving component drives the moving assembly to descend to the lowest position, the corrected reaction cup is detached from the moving assembly and enters the next process. This reduces the occurrence of cup jamming and horizontal cup phenomena during the feeding process, reduces the failure rate, and has high reliability.

[0012] In one alternative embodiment, the inner wall of the receiving channel opposite to the moving component is provided with a plurality of protrusions spaced apart in the vertical direction.

[0013] Beneficial effects: By setting multiple protrusions on the inner wall of the accommodating channel opposite to the moving component, the reaction cup collides with the protrusions during the descent process, improving the overturning and correction effect of the reaction cup, and further reducing the occurrence of cup jamming and horizontal cup phenomena during the feeding process.

[0014] In one alternative implementation, the accommodating channel includes:

[0015] A pair of support plates are arranged opposite to each other along the length of the receiving channel;

[0016] The first guide bar and the second guide bar are disposed opposite to each other between a pair of support plates. The pair of support plates, the first guide bar, and the second guide bar form a channel for the moving component to slide up and down. The first guide bar is provided with a plurality of protrusions at intervals. The moving component is disposed close to the second guide bar.

[0017] Beneficial effects: The receiving channel consists of a pair of support plates, a first guide bar, and a second guide bar. It has a simple structure, low operating cost, and is easy to manufacture and install. The moving component is positioned close to the second guide bar, and a protrusion is located on the first guide bar. Upon colliding with the protrusion, the reaction cup flips towards the second guide bar and descends with the moving component.

[0018] In one alternative implementation, the moving component includes:

[0019] The slide bar is connected to the connector;

[0020] A pair of baffles are disposed on opposite sides of the slide bar and together with the slide bar form a space for accommodating the reaction cup. A fixing ring is sleeved on the periphery of the reaction cup near the opening end. The outer diameter of the reaction cup is smaller than the gap between the pair of baffles, and the outer diameter of the fixing ring is larger than the gap between the pair of baffles.

[0021] When the moving component is moved to its lowest position, there is a gap between the pair of baffles and the first guide strip, the distance from the fixing ring to the opening end of the reaction cup is less than or equal to the gap, and the distance from the fixing ring to the closed end of the reaction cup is greater than the gap.

[0022] Beneficial effects: The drive unit drives the slide bar and a pair of baffles to slide up and down via the connector. The outer diameter of the reaction cup is smaller than the gap between the pair of baffles, and the outer diameter of the fixing ring is larger than the gap between the pair of baffles. The reaction cup portion located at the lower end of the fixing ring is accommodated between the pair of baffles, while the reaction cup portion located at the upper end of the fixing ring is exposed. The fixing ring is positioned close to the open end, so the distance from the fixing ring to the open end of the reaction cup is less than the distance from the fixing ring to the closed end of the reaction cup. When the moving assembly moves to its lowest position, if the open end of the reaction cup is upward, the first guide bar will not obstruct the reaction cup from flowing to the next process. If the closed end of the reaction cup is upward, the first guide bar will block the reaction cup, causing it to remain at the moving assembly. As the moving assembly moves up and down, the reaction cup continues to collide with the protrusion and flip for correction until it is in an upright position.

[0023] In one alternative embodiment, a discharge assembly is further included, which is fixed to the bottom of the receiving channel and communicates with the receiving channel.

[0024] Beneficial effect: The discharge component at the bottom of the receiving channel can receive the sorted reaction cup, so that the sorted reaction cup can smoothly enter the next process.

[0025] In one optional embodiment, the discharge assembly is inclined downward at the lower end of the first guide bar, a pair of baffles are inclined downward toward the first guide bar, and the base is located at the lower end of the second guide bar.

[0026] Beneficial effects: The discharge component is inclined at the lower end of the first guide bar, which facilitates the reception of the reaction cup from the moving component and provides clearance for the base and drive component, preventing the discharge component from interfering with the drive component's ability to move the moving component up and down. A pair of baffles are inclined toward the first guide bar, allowing the reaction cup located between the baffles to slide toward the first guide bar, so that the reaction cup continuously contacts and collides with the protrusions on the first guide bar to correct its position.

[0027] In one optional embodiment, the discharge assembly includes: a plurality of enclosures forming a discharge channel, the discharge channel having an inlet and an outlet, the inlet being connected to the bottom of the receiving channel.

[0028] Beneficial effects: The discharge assembly consists of multiple enclosures, has a simple structure, low manufacturing cost, and is easy to manufacture and install.

[0029] In one alternative embodiment, the top of the first guide bar is further provided with a downwardly inclined cup guide bar.

[0030] Beneficial effects: By setting cup guide bars, the reaction cup can be guided to flow downwards and rotated for correction.

[0031] In one alternative implementation, the protrusion includes regular and irregular shapes, the regular shape including at least one of arc, sphere and column.

[0032] Beneficial effects: The protrusions can be selected in specific shapes as needed, and have a wide range of applications. When the protrusions are arc-shaped, the contact surface is larger, which is beneficial for contact with the reaction cup and will not damage the reaction cup.

[0033] In one optional embodiment, a pulley is provided at the upper and lower ends of one side of the base, the drive shaft of the drive member is connected to one of the pulleys, and the base is also provided with a conveyor belt sleeved between the two pulleys, the conveyor belt being connected to the connector.

[0034] Beneficial effects: The base supports the drive unit, conveyor belt, and a pair of pulleys. The drive unit rotates the pulleys, which in turn rotate the conveyor belt. The conveyor belt then moves the connecting parts and moving components up and down, continuously sorting and transporting multiple reaction cups to the discharge assembly. Compared to the traditional conveyor chain structure, the conveyor belt structure occupies less space, has lower costs, and is more reliable.

[0035] Secondly, this application also provides a feeding device, comprising:

[0036] hopper;

[0037] A pusher is disposed inside the hopper;

[0038] In the above-described feeding device cup-sorting structure, the pusher is used to transport the reaction cup from the hopper to the inlet of the accommodating channel.

[0039] Beneficial effects: The feeding device of this application uses a hopper to carry the reaction cup. The pusher can push the reaction cup from the hopper into the inlet of the receiving channel. The drive unit drives the moving component to rise to the highest position to receive the reaction cup. Then, the drive unit drives the moving component and the reaction cup to descend. During the descent, the reaction cup collides with the inner wall of the receiving channel and flips and corrects itself under the influence of gravity, so that its open end is facing upward and stays in the moving component. When the drive unit drives the moving component to descend to the lowest position, the corrected reaction cup is detached from the moving component and enters the next process. This reduces the occurrence of cup jamming and horizontal cup phenomena during the feeding process, reduces the failure rate, and has high reliability.

[0040] Thirdly, this application also provides a diagnostic device, including: the above-mentioned feeding device cup-sorting structure, or the above-mentioned feeding device.

[0041] Beneficial effects: Since the diagnostic equipment includes a feeding device with a cup-sorting structure or a feeding device, it has the same effect as the feeding device with a cup-sorting structure or a feeding device, so it will not be described in detail here.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] The embodiments of this application are described below with reference to Figures 1 to 9.

[0055] According to an embodiment of this application, as shown in Figures 1 and 2, a feeding device cup-sorting structure is provided, mainly including: a receiving channel 1, a moving component 2, a base 4, and a driving component 5. The receiving channel 1 has a feed inlet 101 at its top. The moving component 2 is disposed within the receiving channel 1 and is movable along its vertical direction, used to support the reaction cup 10. The base 4 is disposed at the lower end of the receiving channel 1, and the driving component 5 is disposed on the base 4. The moving component 2 is connected to the driving component 5 via a connecting component 6, and the driving component 5 is used to drive the moving component 2 to move vertically along the receiving channel 1.

[0056] The feeding device provided in this application has a cup-sorting structure in which the reaction cup 10 enters the accommodating channel 1 from the feed port 101. At the same time, the driving component 5 drives the moving component 2 to rise to the highest position to receive the reaction cup 10. Then, the driving component 5 drives the moving component 2 and the reaction cup 10 to descend. During the descent, the reaction cup 10 collides with the inner wall of the accommodating channel 1 and flips and corrects itself under the influence of gravity, so that its open end is facing upward and stays in the moving component 2. When the driving component 5 drives the moving component 2 to descend to the lowest position, the corrected reaction cup 10 is removed from the moving component 2 and enters the next process. This reduces the occurrence of cup jamming and horizontal cup phenomena during the feeding process, reduces the failure rate, and has high reliability.

[0057] Compared to traditional methods that involve shaping or designing certain parts of the feeding device to separate, guide, and sort the reaction cups 10, or adding separate and guiding structures, the overall structure of this embodiment is simpler, the manufacturing cost is lower, and the cup sorting effect is better and the reliability is higher.

[0058] Specifically, the vertical direction is the height direction of the containing channel 1, as shown by arrow H in Figure 1. The feed inlet 101 is located at the top of the containing channel 1 so that the reaction cup 10 contacts the inner wall of the containing channel 1 from top to bottom and rotates to correct its position. The containing channel 1 is located in the hopper 9 of the feeding device.

[0059] It should be noted that the embodiments of this application do not limit the structure of the driving component 5, and any existing structure can be selected as needed. For example, the driving component 5 is a motor.

[0060] In one embodiment, as shown in FIG2, a plurality of protrusions 102 are spaced apart along the vertical direction on the inner wall of the receiving channel 1 opposite to the moving component 2. The protrusions 102 are used to collide with the reaction cup 10. The closed end of the reaction cup 10 is heavier than the open end. After the reaction cup 10 collides with the protrusions 102, under the influence of gravity, the heavier closed end will point downward and the lighter open end will point upward, resulting in an upright posture. By setting the protrusions 102, the flipping and correction effect of the reaction cup 10 can be improved, further reducing the occurrence of cup jamming and horizontal cup phenomena during the feeding process.

[0061] In one embodiment, as shown in FIG2, the receiving channel 1 mainly includes: a pair of support plates 103, a first guide bar 104, and a second guide bar 105. The pair of support plates 103 are arranged opposite each other along the length direction of the receiving channel 1. The first guide bar 104 and the second guide bar 105 are arranged opposite each other between the pair of support plates 103. The pair of support plates 103, the first guide bar 104, and the second guide bar 105 form a channel for the moving component 2 to slide up and down. The inner wall of the first guide bar 104 is provided with a plurality of protrusions 102 spaced apart in the vertical direction. The moving component 2 is arranged close to the second guide bar 105. The receiving channel 1 is composed of a pair of support plates 103, a first guide bar 104, and a second guide bar 105. It has a simple structure, low cost, and is easy to manufacture and install. The moving component 2 is arranged close to the second guide bar 105. The protrusions 102 are arranged on the first guide bar 104. After colliding with the protrusions 102, the reaction cup 10 will flip towards the second guide bar 105 and descend with the moving component 2.

[0062] It should be noted that the shape of the protrusion 102 is not limited in this embodiment. The protrusion 102 includes regular and irregular shapes. The regular shape includes at least one of arc, sphere and column. The protrusion 102 can be selected according to needs and has a wide range of applications. When the protrusion 102 is arc-shaped, the contact surface is larger, which is beneficial for contact with the reaction cup 10 and will not damage the reaction cup 10.

[0063] In one embodiment, as shown in Figures 4 and 5, the moving component 2 mainly includes a slide bar 201 and a pair of baffles 202. The slide bar 201 is connected to the connector 6. The pair of baffles 202 are disposed on opposite sides of the slide bar 201 and together with the slide bar 201 form a space for accommodating the reaction cup 10.

[0064] Optionally, as shown in Figure 9, a retaining ring 11 is fitted around the periphery of the reaction cup 10 near the open end. The outer diameter of the reaction cup 10 is smaller than the gap between the pair of baffles 202, and the outer diameter of the retaining ring 11 is larger than the gap between the pair of baffles 202. The reaction cup 10 can extend between the pair of baffles 202 and be secured to the pair of baffles 202 by the retaining ring 11.

[0065] Optionally, when the moving component 2 is moved to the lowest position, a gap is left between the pair of baffles 202 and the first guide bar 104, the distance from the fixing ring 11 to the open end of the reaction cup 10 is less than or equal to the gap, and the distance from the fixing ring 11 to the closed end of the reaction cup 10 is greater than the gap.

[0066] In this embodiment, the driving member 5 drives the slide bar 201 and a pair of baffles 202 to slide up and down via the connecting member 6. The outer diameter of the reaction cup 10 is smaller than the gap between the pair of baffles 202, and the outer diameter of the fixing ring 11 is larger than the gap between the pair of baffles 202. The portion of the reaction cup 10 located at the lower end of the fixing ring 11 is accommodated between the pair of baffles 202, while the portion of the reaction cup 10 located at the upper end of the fixing ring 11 is exposed. The fixing ring 11 is positioned close to the open end, therefore the distance from the fixing ring 11 to the open end of the reaction cup 10 is smaller than the distance from the fixing ring 11 to the closed end of the reaction cup 10.

[0067] When the moving component 2 is at its lowest position, as shown in Figure 2, if the open end of the reaction cup 10 is facing upwards, the first guide bar 104 will not obstruct the reaction cup 10 from flowing to the next process. As shown in Figures 3 and 4, if the closed end of the reaction cup 10 is facing upwards, the first guide bar 104 will block the reaction cup 10, causing the reaction cup 10 to remain at the moving component 2. As the moving component 2 moves up and down, it continues to collide with the protrusion 102 and flip and correct itself until it is in an upright position.

[0068] Optionally, the slider 201 can be slidably connected to the second guide bar 105 to improve the movement stability of the slider 201 and the pair of baffles 202. For example, the inner side of the second guide bar 105 is provided with a slide rail, and the side of the slider 201 near the second guide bar 105 is provided with a slider that cooperates with the slide rail. The pair of baffles 202 can be fixedly connected to the slider 201 by fasteners, such as screws or bolts. As shown in Figure 5, the lower ends of the pair of baffles 202 away from the slider 201 can also be fixed by connecting posts 203 to improve the connection stability of the pair of baffles 202.

[0069] In one embodiment, as shown in FIG1, a discharge component 3 is further included. The discharge component 3 is fixed to the bottom of the receiving channel 1 and communicates with the receiving channel 1, forming a discharge channel for the transfer reaction cup 10. The discharge component 3 at the bottom of the receiving channel 1 can receive the sorted reaction cup 10 so that the sorted reaction cup 10 can smoothly enter the next process.

[0070] Optionally, in one embodiment, as shown in Figures 1 and 2, the discharge assembly 3 is inclined downwards at the lower end of the first guide bar 104, a pair of baffles 202 are inclined downwards toward the first guide bar 104, and the base 4 is located at the lower end of the second guide bar 105. This facilitates receiving the reaction cup 10 from the moving assembly 2, and also provides clearance for the base 4 and the driving component 5, preventing the discharge assembly 3 from affecting the driving component 5's ability to drive the moving assembly 2 to slide up and down. The inclination of the pair of baffles 202 toward the first guide bar 104 allows the reaction cup 10 located between the baffles 202 to slide toward the first guide bar 104, causing the reaction cup 10 to continuously contact and collide with the protrusions 102 on the first guide bar 104 to correct its position.

[0071] Specifically, when the open end of the reaction cup 10 is tilted upwards and located between a pair of baffles 202, the collision between the reaction cup 10 and the protrusion 102 will not cause the reaction cup 10 to flip due to gravity. When the closed end of the reaction cup 10 is tilted upwards and located between a pair of baffles 202, the collision between the reaction cup 10 and the protrusion 102 will cause the reaction cup 10 to flip due to gravity, thus achieving the effect of correcting the position.

[0072] Optionally, in one embodiment, the tilt angle of the pair of baffles 202 is the same as the tilt angle of the discharge assembly 3, so that the reaction cup 10 can smoothly detach from the pair of baffles 202 and enter the discharge assembly 3.

[0073] Optionally, in one embodiment, the protrusion 102 extends to the lower end of the first guide bar 104. As shown in Figures 3 and 4, when the moving assembly 2 has multiple reaction cups 10, if the open end of the first reaction cup 10 near the first guide bar 104 of the moving assembly 2 is upward and the closed end of the second reaction cup 10 is upward, when the moving assembly 2 moves to its lowest position, the first reaction cup 10 can directly enter the discharge channel of the discharge assembly 3. The protrusion 102 at the lower end contacts the second reaction cup 10. Due to the presence of the protrusion 102, the closed end of the reaction cup 10 will tilt towards one side of the second guide bar 105 and flip into an upright posture under the action of gravity before entering the discharge channel of the discharge assembly 3, thereby achieving the cup sorting effect.

[0074] It should be noted that the size of the protrusion 102 should not be too large or too small. If it is too large, it will easily cause the upright reaction cup 10 to flip over. If it is too small, it will be impossible to flip the non-upright reaction cup 10.

[0075] For example, as shown in Figure 7, the protrusion 102 is provided in two segments, with multiple protrusions 102 spaced apart in each segment. The distance between the two protrusions 102 is A, which can be selected from 20mm to 30mm, for example, A is 24mm. Half the thickness of the first guide strip 104 is dimension B, which can be 4mm. Multiple cylinders are provided inside the first guide strip 104. One end of the cylinder is attached to the inner side of the first guide strip 104, and the other end protrudes from the first guide strip 104. The radius of the cylinder is R3, which can be 6mm. An arc is cut from the upper end of the protruding part of the cylinder to form an arc segment with a radius of R1, which is tangent to the surface of the cylinder. R1 can be 0.6mm, and the central angle is 120°. Another arc segment with a radius of R2 is provided tangent to the lower end of the protruding part of the cylinder. R2 can be 6mm. The two arc segments and the remaining part of the cylinder together form the protrusion 102.

[0076] In one embodiment, as shown in FIG6, the discharge assembly 3 includes multiple enclosures 301 forming a discharge channel, the discharge channel having an inlet and an outlet, the inlet being connected to the bottom of the receiving channel 1. The discharge assembly 3 is composed of multiple enclosures 301, has a simple structure, low manufacturing cost, and is convenient to manufacture and install.

[0077] Specifically, as shown in Figure 6, the plurality of enclosure plates 301 include a pair of oppositely arranged side plates 3011. The distance between the pair of side plates 3011 is greater than the outer diameter of the reaction cup 10 but less than the outer diameter of the fixing ring 11. A shield 3012 is also provided on the outer side of each pair of side plates 3011. The distance between the pair of shields 3012 is greater than the outer diameter of the fixing ring 11 to facilitate transporting the reaction cup 10. A support column 3013 is also connected to the bottom of the pair of side plates 3011, and the support column 3013 is used to fix the pair of side plates 3011.

[0078] In one embodiment, as shown in FIG1, the top of the first guide bar 104 is further provided with a downwardly inclined cup guide bar 106. By providing the cup guide bar 106, the reaction cup 10 can be guided to flow downward and rotated for correction.

[0079] In one embodiment, as shown in Figures 4 and 8, a pulley 7 is provided at the upper and lower ends of one side of the base 4, the drive shaft of the drive member 5 is connected to one of the pulleys 7, and the base 4 is also provided with a conveyor belt 8 sleeved between the two pulleys 7, and the conveyor belt 8 is connected to the connector 6.

[0080] The base 4 in this embodiment supports the drive unit 5, the conveyor belt 8, and a pair of pulleys 7. The drive unit 5 drives the pulleys 7 to rotate, which in turn drives the conveyor belt 8 to rotate. The conveyor belt 8 then drives the connecting member 6 and the moving component 2 to move up and down, so as to continuously arrange and transport multiple reaction cups 10 to the discharge component 3. Compared with the traditional conveyor chain structure, the use of the conveyor belt 8 occupies less space, has lower cost, and is more reliable.

[0081] Optionally, as shown in Figure 8, the connector 6 is provided with a clamping part 601 for clamping the conveyor belt 8, so as to achieve a fixed connection with the conveyor belt 8 and smooth movement.

[0082] According to an embodiment of this application, as shown in FIG8, a feeding device is also provided, mainly comprising: a hopper 9, a pusher, and a feeding device cup sorting structure. The pusher is disposed inside the hopper 9. The pusher is used to transport the reaction cup 10 from inside the hopper 9 to the inlet 101 of the receiving channel 1.

[0083] The feeding device provided in this application embodiment uses a hopper 9 to carry the reaction cup 10. The pusher can push the reaction cup 10 from the hopper 9 into the feed inlet 101 of the receiving channel 1. The drive 5 drives the moving component 2 to rise to the highest position to receive the reaction cup 10. Then, the drive 5 drives the moving component 2 and the reaction cup 10 to descend. During the descent, the reaction cup 10 collides with the protrusion 102 and flips and corrects itself under the influence of gravity, so that its open end is facing upward and stays in the moving component 2. When the drive 5 drives the moving component 2 to descend to the lowest position, the corrected reaction cup 10 is removed from the moving component 2 and enters the next process. This reduces the occurrence of cup jamming and horizontal cup phenomena during the feeding process, reduces the failure rate, and has high reliability.

[0084] In one embodiment, the pusher is fixedly connected to the connector 6, and the drive 5 simultaneously drives the pusher and the moving component 2 to move up and down, thereby simplifying the structure of the feeding device and improving space utilization. The pusher can drive one or more reaction cups 10 into the feed inlet 101 at a time.

[0085] The working principle of this application embodiment is as follows:

[0086] The drive unit 5 drives the pusher to push the reaction cup 10 from the hopper 9 into the feed inlet 101 of the receiving channel 1. At the same time, the drive unit 5 drives the moving assembly 2 to rise to its maximum height to receive the reaction cup 10. Afterwards, the drive unit 5 drives the moving assembly 2 to descend.

[0087] As shown in Figure 1, under the influence of gravity, the reaction cup 10 slides between a pair of baffles 202 toward the first guide bar 104 and continuously collides with multiple protrusions 102. If the closed end of the reaction cup 10 faces upward, it will flip over after the collision. If the reaction cup 10 lies horizontally in the receiving channel 1, it will also be flipped over due to the resistance of the protrusions 102, until the open end of the reaction cup 10 faces upward and tilts and stays between the pair of baffles 202.

[0088] As shown in Figure 2, after the driving component 5 drives the moving component 2 to descend to the lowest position, the reaction cup 10 with the opening end facing upward can smoothly enter the discharge channel of the discharge component 3.

[0089] As shown in Figures 3 and 4, if the closed end of the reaction cup 10 is facing upward, it will be blocked by the first guide bar 104 and will not be able to enter the discharge channel of the discharge assembly 3.

[0090] According to an embodiment of this application, in another aspect, a diagnostic device is also provided, including: the above-described feeding device cup-sorting structure, or the above-described feeding device.

[0091] Since the diagnostic equipment includes a feeding device, a cup-sorting structure, or a feeding device, and has the same effect as the feeding device, it will not be described in detail here.

[0092] Diagnostic equipment includes, but is not limited to, immunoassay analyzers, biochemical analyzers, and blood gas analyzers.

[0093] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
