Description

Technical Field

[0001] This application relates to the field of blood collection device technology, and more particularly to a blood collection device for blood type detection. Background Technology

[0002] Blood typing is a crucial and fundamental step in clinical diagnosis and treatment, blood transfusion matching, health checkups, and emergency rescue. Its efficiency directly impacts the quality of medical services and the timeliness of emergency response. Currently, blood sample collection for blood typing still largely relies on manual operation and has not yet been automated. This situation severely restricts the efficient advancement of the testing process and makes it difficult to meet the ever-increasing demand for large-scale testing.

[0003] Current manual blood sample collection procedures require multiple steps: medical staff must first verify patient information, prepare blood collection equipment (capillary needles, collection cups, disinfectants, etc.), then manually disinfect and position the patient's fingertip, and finally complete the puncture and blood collection and transfer of the blood sample to the collection cup. The entire process typically takes 5-10 minutes. In large-scale screening scenarios such as peak health check-up periods and public health emergencies, the inefficiency of manual collection is particularly pronounced, easily leading to excessively long patient waiting times and a surge in the workload of medical staff.

[0004] Meanwhile, the stability of manual blood collection is greatly affected by the operator's experience. Issues such as fingertip positioning deviation, improper puncture depth, and contamination during blood sample transfer can lead to collection failure or substandard sample quality, further reducing testing efficiency. Furthermore, in resource-limited scenarios such as primary healthcare institutions and outdoor emergency testing, the shortage of professional blood collection personnel further limits the applicability of manual blood collection, hindering rapid response to testing needs.

[0005] In summary, the current blood typing method, which relies on manual blood sample collection, suffers from many drawbacks, such as low efficiency, poor operational stability, and limited applicability. There is an urgent need for a technical solution that can achieve automated blood sample collection in order to overcome the current technical bottlenecks and improve the overall efficiency and reliability of blood typing.

[0022] Example 1 Please see Figures 1-7A blood collection device for blood typing includes: a housing 100, an automatic blood collection device, a power supply module, and a tablet computer 200; the automatic blood collection device is located in the lower part of the housing 100, and an opening 300 is provided in the middle part of the housing 100, with the bottom surface of the opening 300 inclined upwards; the power supply module is located in the upper part of the housing 100, and the tablet computer 200 is mounted on the top surface of the housing 100; the automatic blood collection device includes an automatic capillary needle replenishment unit 400, an automatic collection cup replenishment unit 500, and a circulating lifting mechanism 600, the working part of the circulating lifting mechanism 600 being perpendicular to the bottom surface of the opening 300 and facing the bottom surface. The surface is configured such that the bottom surface of the open port 300 has a collection hole 700 for the capillary needle to pass through; the automatic capillary needle replenishment unit 400 and the automatic collection cup replenishment unit 500 are both configured corresponding to the circulating lifting mechanism 600, and are respectively used to push the capillary needle and the collection cup 532 to the working part of the circulating lifting mechanism 600; the circulating lifting mechanism 600 is adapted to the collection cup 532 and the capillary needle, and is used to lift the collection cup 532 and make the opening of the collection cup 532 snap into the end of the capillary needle away from the collection end, and drive the assembled collection cup 532 and the capillary needle to move towards the collection hole 700, so that the collection end of the capillary needle can pass through the collection hole 700.

[0023] In the above embodiments, when the device is working, the power supply module supplies power to each electrical component, and the tablet computer 200 displays the complete blood collection operation process in real time. At the same time, it supports users to complete payment by scanning a QR code, realizing autonomous blood sample collection operation. Following the tablet's instructions, the user places their fingertip at the corresponding position in the open port 300. The automatic capillary tube replenishment unit 400 then pushes the capillary tube to the working section of the circulating lifting mechanism 600. Simultaneously, the automatic collection cup replenishment unit 500 pushes the collection cup 532 to the same working section. The circulating lifting mechanism 600 is activated, first lifting the collection cup 532. Through thrust, the end of the capillary tube furthest from the collection end is inserted into the opening of the collection cup 532 to complete assembly. Subsequently, the assembled collection cup 532 and capillary tube move towards the collection hole 700. The collection end of the capillary tube passes through the collection hole 700 and pierces the fingertip, collecting blood into the collection cup 532 through capillary action. After collection, the circulating lifting mechanism 600 resets the collection cup 532 and capillary tube and pushes them out of the housing 100. The user or staff manually removes and discards the capillary tube, sending only the collection cup 532 containing the blood sample to the testing department.

[0024] Through the coordinated operation of various components, the entire blood sample collection process is automated, completely eliminating reliance on manual operation and significantly improving blood collection efficiency. The combination of the QR code scanning payment function and operation guidance function of the tablet computer 200 constructs an autonomous collection mode, which can be adapted to large-scale testing scenarios such as physical examination centers and community hospitals, reducing the labor intensity of medical staff. The precise matching of the assembly and motion design of each component avoids problems such as positioning deviation and non-standard operation in the manual collection process, improving the stability of blood sample collection and sample quality. The device has a high degree of integration and is easy to operate, effectively filling the gap in existing technologies for automated collection and enhancing the continuity and efficiency of the blood typing process.

[0025] Example 2 Please see Figures 1-7 The outer wall of the housing 100 is equipped with a fingertip disinfection device 800; the fingertip disinfection device 800 includes a housing 810, a winding roller 820, a feeding roller 830, a winding motor 840, a ratchet mechanism 850, a disinfection cotton strip 860, and a closed chamber 870; the housing 810 is detachably connected to the outer wall of the housing 100, the winding roller 820 and the feeding roller 830 are spaced apart and rotatably mounted on the inner wall of the housing 810, one end of the winding roller 820 is connected to the winding motor 840, and the feeding roller 830 feeds the material... One end of roller 830 is provided with a ratchet mechanism 850; the disinfectant cotton strip 860 is wrapped around the outer wall of the feed roller 830, and the end of it away from the feed roller 830 is connected to the outer wall of the winding roller 820, and the disinfectant cotton strip 860 between the winding roller 820 and the feed roller 830 is arranged in a downward position, and this downward section is used for fingertip disinfection; the closed chamber 870 is provided inside the housing 810 and covers the outside of the feed roller 830, and the closed chamber 870 has a strip-shaped hole for the disinfectant cotton strip 860 to pass through.

[0026] In the above embodiment, before blood collection, the winding motor 840 starts and drives the winding roller 820 to rotate. The winding roller 820 drives the sterile cotton strip 860 to move to one side through friction. At this time, the dispensing roller 830 rotates synchronously under the traction of the sterile cotton strip 860. The ratchet mechanism 850 at one end of the dispensing roller 830 can limit the reverse rotation of the dispensing roller 830 to ensure the stable release of the sterile cotton strip 860. After the sterile cotton strip 860 wound on the dispensing roller 830 passes through the strip hole of the closed chamber 870, it remains in a hanging state. The user can then... Following the instructions on the tablet computer 200, press your fingertip onto the drooping section of the disinfectant cotton strip 860 to complete the disinfection. After a single disinfection is completed, the winding motor 840 continues to drive the winding roller 820 to rotate at a preset angle, winding the used disinfectant cotton strip 860 onto the winding roller 820. At the same time, it drives the unloading roller 830 to release a new unused disinfectant cotton strip 860 to the drooping position, waiting for the next disinfection operation. The detachable connection design between the housing 810 and the outer wall of the box 100 facilitates subsequent maintenance of internal components or replacement of the disinfectant cotton strip 860.

[0027] The device automates fingertip disinfection, eliminating the need for manual application of disinfectant, further improving the automated blood sample collection process and enhancing overall operational efficiency. The single-use, immediate replacement design of the disinfectant strip 860 effectively prevents cross-infection between different users, ensuring the hygiene and safety of the disinfection operation. The enclosed chamber 870 protects the unused disinfectant strip 860 on the dispensing roller 830 from dust and contamination, ensuring the disinfection effect of the strip. The ratchet mechanism 850 ensures the stability of the strip release process, preventing loosening or over-release. The detachable housing 810 design improves the ease of maintenance, reduces subsequent operating costs, and allows the disinfection device to stably adapt to the overall needs of automated collection.

[0028] Example 3 Please see Figures 1-7 The bottom surface of the open opening 300 is also provided with a fingertip positioning device 900; the fingertip positioning device 900 includes a positioning cover 910 and a heating film 930; the positioning cover 910 is placed on one side of the collection hole 700, and has a passage 920 for the fingertip to enter, and the inner wall contour of the positioning cover 910 is adapted to the fingertip contour to lock the fingertip; the heating film 930 is attached to the bottom surface of the open opening 300, and its circuit is electrically connected to the power supply module.

[0029] In the above embodiment, the working principle is as follows: After the fingertip disinfection is completed, the user inserts the fingertip into the positioning cover 910 through the through-hole 920 according to the guidance of the tablet computer 200. Since the inner wall contour of the positioning cover 910 is adapted to the contour of the fingertip, the fingertip can be accurately positioned after insertion, ensuring that the blood collection site of the fingertip is precisely aligned with the collection hole 700 on the bottom surface of the open opening 300. The power supply module supplies power to the heating film 930. After the heating film 930 is powered on, it generates heat and transfers it to the bottom surface of the open opening 300, thereby gently heating the positioned fingertip. After the heating process continues to the preset state, the circulating lifting mechanism 600 drives the assembled capillary tube and the collection cup 532 to move towards the collection hole 700. After the capillary tube collection end passes through the collection hole 700, it can accurately pierce the blood collection site of the fingertip to complete the blood collection. After the blood collection is completed, the user only needs to pull the fingertip out of the through-hole 920 of the positioning cover 910. The heating film 930 stops heating when the power supply module is de-energized.

[0030] The precise positioning function of the positioning cover 910 effectively avoids blood collection failures caused by fingertip positioning deviations during manual collection, ensuring that the capillary needle can accurately pierce the blood collection site and improving the success rate of blood sample collection. The heating film 930 promotes blood circulation in the fingertip area, making the blood collection process smoother and reducing problems such as excessively long collection time or insufficient collection volume caused by slow blood flow. The electrical connection design between the heating film 930 and the power supply module enables automated control of the heating operation without manual intervention, meeting the needs of overall automated collection. The positioning device has a simple structure and compact size, which can be efficiently integrated with the bottom surface of the open port 300 without occupying extra space. At the same time, it is easy to operate, improving the user experience and further ensuring the stability and reliability of blood sample collection.

[0031] Example 4 Please see Figures 1-7 The automatic capillary needle replenishment unit 400 includes a mounting plate 410, a capillary needle guide rail 420, a capillary needle positioning guide rail 430, a first push rod 440, a tension spring 450, a second push rod 460, a moving rail 470, a crank rod 480, and a first drive motor. The mounting plate 410 is mounted on one side of the automatic liquid collection cup replenishment unit 500. The capillary needle guide rail 420 is mounted on the side of the mounting plate 410 near the automatic liquid collection cup replenishment unit 500, and its end is aligned with the output end of the liquid collection cup 532 of the automatic liquid collection cup replenishment unit 500. The capillary needle positioning guide rail 430 is mounted on one side of the capillary needle guide rail 420, and its opening is aligned with the capillary needle... The sidewall of the tube guide rail 420 is open, and several capillary tubes are placed sequentially inside it along its extension direction; the first push rod 440 passes through the end wall of the capillary tube positioning guide rail 430 away from its opening; one end of the tension spring 450 is connected to the end wall of the first push rod 440, and the other end is connected to the outer wall of the capillary tube positioning guide rail 430 near the capillary tube guide rail 420; one end of the second push rod 460 is slidably disposed inside the capillary tube guide rail 420; the outer wall of the moving rail 470 is connected to the end wall of the second push rod 460 and is disposed at the opening of the capillary tube guide rail 420; one end of the crank rod 480 is slidably disposed inside the moving rail 470, and the other end is connected to the first drive motor.

[0032] In the above embodiment, several capillary tubes are pre-placed in the capillary tube positioning guide rail 430 along the extension direction. Under the tension of the tension spring 450, the first push rod 440 continuously applies a pushing force towards the opening direction of the capillary tube positioning guide rail 430, pushing the internal capillary tubes to move towards the opening, so that the capillary tube closest to the opening can enter the capillary tube guide rail 420 connected to the opening. When it is necessary to push the capillary tubes to the cyclic lifting mechanism 600, the first drive motor starts and drives the crank 480 to rotate. During the rotation of the crank 480, one end slides in the moving rail 470, thereby driving the moving rail 470 to perform reciprocating linear motion. The moving rail 470 drives the second push rod 460 connected to it. The capillary needle slides within the capillary needle guide rail 420; during the sliding process of the second push rod 460, it pushes the capillary needle within the capillary needle guide rail 420 to move to the end of the guide rail. Since the end of the capillary needle guide rail 420 is aligned with the output end of the collection cup 532 of the automatic collection cup replenishment unit 500, the capillary needle is precisely pushed to the working part of the cyclic lifting mechanism 600; after the push is completed, the first push rod 440 continues to push subsequent capillary needles into the capillary needle guide rail 420 under the action of the tension spring 450, waiting for the next push operation; the mounting plate 410 realizes the stable connection between the entire automatic capillary needle replenishment unit 400 and the automatic collection cup replenishment unit 500, ensuring the coordination of their actions.

[0033] Through the coordinated operation of various components, automated continuous replenishment and precise delivery of capillary needles are achieved, eliminating the need for manual placement and transfer of capillary needles, significantly improving the automation and efficiency of blood sample collection. The coordinated design of the tension spring 450 and the first push rod 440 ensures that the capillary needles within the capillary needle positioning guide rail 430 are continuously in a ready-to-deliver state, guaranteeing continuous replenishment and preventing collection interruptions due to needle shortages. The stable transmission structure of the crank rod 480, moving rail 470, and second push rod 460 enables precise delivery of the capillary needles, ensuring they are aligned with the collection cup 532 in a circulating top position. The lifting mechanism has 600 precise connections. After the capillary needle and the collection cup 532 are lifted by the circulating lifting mechanism 600, the pushing force allows one end of the capillary needle to be stably embedded in the mouth of the collection cup 532. During the collection process, after the end of the capillary needle pierces the fingertip, the blood can be stably collected in the collection cup 532 through capillary action. After the collection is completed, the collection cup 532 and the capillary needle are pushed out of the box 100. The operator only needs to remove the capillary needle and discard it, and only the collection cup 532 is sent to the testing department. This further simplifies the subsequent operation process, reduces the manual intervention, and avoids the contamination problem caused by manual contact with blood samples.

[0034] Example 5 Please see Figures 1-7The automatic liquid collection cup replenishment unit 500 includes a liquid collection cup limiting guide rail 510, an intermittent gripping mechanism 520, and a liquid collection cup storage box 530. The liquid collection cup limiting guide rail 510 is inclined, its extension direction is towards the collection hole 700, and the end away from the collection hole 700 is open. The intermittent gripping mechanism 520 is located at the lower part of the end of the liquid collection cup limiting guide rail 510 away from the collection hole 700. The liquid collection cup storage box 530 is located on one side of the intermittent gripping mechanism 520. The intermittent gripping mechanism 520 is used to grip the liquid collection cup 532 in the liquid collection cup storage box 530 and place it at the open end of the liquid collection cup limiting guide rail 510. The circulating lifting mechanism 600 is installed at the open end of the liquid collection cup limiting guide rail 510, and one side of the mounting plate 410 is connected to the side wall of the liquid collection cup limiting guide rail 510.

[0035] In the above embodiment, a number of collection cups 532 are pre-stored in the collection cup storage box 530. When it is necessary to replenish the collection cups 532, the intermittent gripping mechanism 520 is activated and performs an intermittent gripping action to grab a single collection cup 532 from the collection cup storage box 530. After the gripping is completed, the intermittent gripping mechanism 520 transfers the collection cup 532 to the open end of the collection cup limiting guide rail 510 and places it there. Since the collection cup limiting guide rail 510 is inclined and extends towards the collection hole 700, the collection cup 532 moves along the limiting guide rail towards the open end under its own gravity. The ring lifting mechanism 600 slides and finally stops precisely at the working part of the circulating lifting mechanism 600, corresponding to the capillary needle pushed by the capillary needle automatic replenishment unit 400; the circulating lifting mechanism 600 is installed at the open end of the liquid collection cup limiting guide rail 510, and can directly lift the stopped liquid collection cup 532; the connection between the mounting plate 410 and the side wall of the liquid collection cup limiting guide rail 510 further strengthens the connection stability between the capillary needle automatic replenishment unit 400 and the liquid collection cup automatic replenishment unit 500, ensuring that the components pushed by the two can be accurately docked.

[0036] The system achieves automated grasping, transport, and positioning of the collection cup 532, eliminating the need for manual placement. Working in conjunction with the automatic capillary needle replenishment unit 400, it constructs a complete automated blood collection component supply system, significantly improving the overall efficiency of blood sample collection. The inclined design of the collection cup limiting guide rail 510 utilizes gravity to achieve automatic sliding positioning of the collection cup 532, eliminating the need for additional drive components, simplifying the structural design, and reducing energy consumption. The intermittent action design of the intermittent grasping mechanism 520 enables precise control of the supply of the collection cup 532. The frequency is controlled to avoid accumulation or insufficient supply of the collection cup 532, ensuring the stability of the supply. The integrated design of the circulating lifting mechanism 600 and the open end of the limiting guide rail ensures that the collection cup 532 can quickly enter the lifting assembly process, shortening the component transfer time. After the collection cup 532 and the capillary needle are assembled and blood is collected, it can be pushed out of the box 100 with the action of the circulating lifting mechanism 600. Subsequently, the capillary needle is manually removed and discarded, and the collection cup 532 is retained for testing. The whole process is smooth and further improves the continuity of the testing process.

[0037] Example 6 Please see Figures 1-7 The intermittent gripping mechanism 520 includes a first column 521, a first rod 522, a second rod 523, a third rod 524, a fourth rod 525, a second column 526, a fifth rod 527, a sixth rod 528, and an electrically telescopic rod 529. The first column 521 is located on one side of the liquid collection cup storage box 530. The first rod 522 is horizontally arranged with one end penetrating the upper side wall of the first column 521. The second rod 523 penetrates the outer wall of the end of the first rod 522 away from the first column 521. The third rod 524 is fixedly connected to the end of the second rod 523 near the liquid collection cup limiting guide rail 510. The third rod 524 is located away from the second rod 526. One end of rod 3 passes through one end of the fourth rod 525; the second column 526 is located on the side of the first column 521 near the liquid collection cup limiting guide rail 510; the end of the fourth rod 525 away from the third rod 524 is rotatably connected to the top side wall of the second column 526; one end of the fifth rod 527 passes through the side wall of the second column 526 and is fixedly connected to the fourth rod 525; one end of the sixth rod 528 is fixedly connected to the end of the fifth rod 527 away from the fourth rod 525 and the two are set at an angle; the top extension end of the electric telescopic rod 529 is hinged to the end of the sixth rod 528 away from the fifth rod 527, and its mounting end is hinged to the inner bottom surface of the box 100.

[0038] In the above embodiment, when it is necessary to grasp the collection cup 532, the electric telescopic rod 529 is activated and extends, its extended end pushing the sixth rod 528 to rotate around the connection point between the fifth rod 527 and the sixth rod 528; since the sixth rod 528 and the fifth rod 527 are fixedly connected and set at an angle, the rotation of the sixth rod 528 drives the fifth rod 527 to rotate synchronously. The fifth rod 527 passes through the side wall of the second column 526 and is fixedly connected to the fourth rod 525, thereby driving the fourth rod 525 to rotate around its rotational connection point with the top side wall of the second column 526; during the rotation of the fourth rod 525, its end away from the second column 526 drives the through-connected third rod 524 to move, and the third rod 524 moves through the second rod The fixed connection of 523 drives the movement of the second rod 523. The second rod 523 passes through the outer wall of the end of the first rod 522 away from the first column 521, thereby causing the first rod 522 to slide horizontally within the upper side wall of the first column 521. Through the linkage transmission of each rod, the third rod 524 is finally driven to achieve the preset grasping action, grasping a single liquid collection cup 532 from the liquid collection cup storage box 530. After the grasping is completed, the electric telescopic rod 529 retracts, and through the above reverse transmission process, the third rod 524 is driven to transfer the liquid collection cup 532 to the open end of the liquid collection cup limiting guide rail 510 and release it. The first column 521 and the second column 526 provide stable support for the entire grasping mechanism, ensuring that the transmission action of each rod is accurate and stable.

[0039] Through the coordination of multiple linkages and the electric telescopic rod 529, the automated intermittent gripping and transfer of the collection cup 532 is achieved. The transmission structure is precise and stable, ensuring the consistency and reliability of the gripping action and avoiding problems such as the collection cup 532 falling off or being deviated during transfer. The assembly design of each rod and column is reasonable, providing stable support and being able to withstand the forces during the gripping process, thus improving the service life of the mechanism. As a driving component, the electric telescopic rod 529 has a fast response speed and stable driving force. By controlling the extension amount, the rotation angle of each rod can be precisely controlled, thereby controlling the gripping stroke and release position of the third rod 524, achieving precise gripping and placement of the collection cup 532. The intermittent gripping mechanism 520 has a compact structural design and can be efficiently integrated between the collection cup storage box 530 and the limiting guide rail without occupying too much space. It has good synergy with other components of the automatic collection cup replenishment unit 500, effectively ensuring the continuity and stability of the supply of the collection cup 532, and providing reliable support for the smooth progress of the overall automated collection process.

[0040] Example 7 Please see Figures 1-7 The intermittent gripping mechanism 520 also includes a plurality of electric suction cups 540; the plurality of electric suction cups 540 are spaced apart on the circumferential outer wall of the third rod 524, and their circuits are electrically connected to the power supply unit, for sucking up the liquid collection cups 532 in the liquid collection cup storage box 530.

[0041] In the above embodiment, when the third rod 524 of the intermittent gripping mechanism 520 moves to the liquid collection cup 532 in the liquid collection cup storage box 530 under the linkage of the rods, the power supply unit supplies power to the multiple electric suction cups 540. The electric suction cups 540 generate suction force after being energized. Since the electric suction cups 540 are spaced apart on the circumferential outer wall of the third rod 524, they can adsorb and fix the liquid collection cup 532 circumferentially, ensuring that the liquid collection cup 532 is stably adsorbed onto the third rod 524. After attachment, the third rod 524, driven by the linkage mechanism, transports the liquid collection cup 532 to the open end of the liquid collection cup limiting guide rail 510. When the liquid collection cup 532 reaches the preset placement position, the power supply unit stops supplying power to the electric suction cup 540, the suction force disappears, and the liquid collection cup 532 is stably placed in the open end of the liquid collection cup limiting guide rail 510 under its own gravity. The spacing of multiple electric suction cups 540 can adapt to the circumferential contour of the liquid collection cup 532, ensuring the stability of the suction.

[0042] The electric suction cup 540 significantly improves the gripping stability of the intermittent gripping mechanism 520 on the collection cup 532, avoiding the slippage and breakage problems that may occur with traditional mechanical gripping, and ensuring the integrity of the collection cup 532 during the transfer process. Multiple spaced electric suction cups 540 can adsorb the collection cup 532 from all circumferential directions, improving the reliability of adsorption, adapting to different sizes of collection cups 532, and enhancing the versatility of the mechanism. The electrical connection design between the electric suction cup 540 and the power supply unit enables both adsorption and release actions. The automated control, in precise coordination with the intermittent gripping mechanism 520, further enhances the automation level of the gripping process. The suction method of the electric suction cup 540 will not damage the opening or inner wall of the collection cup 532, ensuring the cleanliness of the collection cup 532 and avoiding the risk of blood sample contamination caused by the gripping process, thus ensuring the quality of subsequent blood samples. At the same time, the suction gripping operation is convenient and responsive, which can further improve the gripping and transportation efficiency of the collection cup 532, meeting the high-efficiency requirements of the overall automated collection.

[0043] Example 8 Please see Figures 1-7The liquid collection cup storage box 530 includes a supply guide rail 531, a plurality of liquid collection cups 532, a movable plate 533, and a spring 534. The supply guide rail 531 is located on the bottom surface of the box body 100, and its extension direction is in the same horizontal plane as the extension direction of the liquid collection cup limiting guide rail 510. The plurality of liquid collection cups 532 are arranged sequentially in the supply guide rail 531 along the extension direction of the supply guide rail 531, and the height of the liquid collection cups 532 is higher than the surface height of the supply guide rail 531. The movable plate 533 is located on the side of the supply guide rail 531 away from the liquid collection cup limiting guide rail 510, and is slidably assembled in the supply guide rail 531, with one end abutting against one side of the plurality of continuously arranged liquid collection cups 532. The spring 534 is located in the supply guide rail 531, with one end abutting against the movable plate 533.

[0044] In the above embodiment, multiple collection cups 532 are pre-arranged sequentially along the extension direction within the supply guide rail 531. Since the extension direction of the supply guide rail 531 and the extension direction of the collection cup limiting guide rail 510 are on the same horizontal plane, it can be ensured that the collection cups 532 can be accurately transferred to the collection cup limiting guide rail 510 after being grasped. The moving plate 533 is slidably mounted on the side of the supply guide rail 531 away from the collection cup limiting guide rail 510. The spring 534 is in a compressed state within the supply guide rail 531, and one end of the spring 534 applies a continuous pushing force to the moving plate 533, pushing the moving plate 533 to slide towards the collection cup limiting guide rail 510. During the sliding process, one end of the moving plate 533 is in contact with the... The outermost collection cup 532 abuts against and pushes the entire arrangement of collection cups 532 toward the end of the supply guide rail 531 that is closer to the intermittent gripping mechanism 520, so that the collection cup 532 closest to the intermittent gripping mechanism 520 is always in the position to be gripped; after the intermittent gripping mechanism 520 grips a collection cup 532 from the supply guide rail 531, the thrust of the spring 534 pushes the moving plate 533 to continue sliding, driving the remaining collection cups 532 forward to replenish, ensuring that the outermost collection cup 532 is always in the position to be gripped; the height of the collection cup 532 is higher than the surface height of the supply guide rail 531, which makes it easy for the electric suction cup 540 of the intermittent gripping mechanism 520 to adsorb and grip it from the circumference.

[0045] Through the coordinated design of the supply guide rail 531, the moving plate 533, and the spring 534, the automated continuous replenishment of the collection cup 532 is achieved, ensuring that the intermittent gripping mechanism 520 can continuously acquire the collection cup 532. This avoids the problem of collection process stagnation caused by interruption of the supply of the collection cup 532, and improves the continuous working capability of the overall device. The continuous thrust of the spring 534 is stable and can push the collection cup 532 to move at a uniform speed, avoiding the problem of accumulation of the collection cup 532 or collision damage caused by excessive speed. The extension direction of the supply guide rail 531 is in the same horizontal plane as the collection cup limiting guide rail 510, ensuring that the collection cup 532 is in a stable position. The smooth transfer path from the storage box to the limiting guide rail reduces the risk of deviation during transfer and improves the accuracy of supply. The design of the liquid collection cup 532 being higher than the surface of the supply guide rail 531 facilitates the gripping action of the intermittent gripping mechanism 520, ensuring that the electric suction cup 540 can accurately adsorb the liquid collection cup 532 and improve the gripping success rate. The entire liquid collection cup storage box 530 has a simple structure and high reliability, without the need for additional complex drive components, reducing the manufacturing cost and maintenance difficulty of the equipment. At the same time, it can adapt to the storage needs of a large number of liquid collection cups 532, providing support for the large-scale application of automated collection.

[0046] Example 9 Please see Figures 1-7 The circulating lifting mechanism 600 includes: a positioning plate 610 disposed at the opening of the liquid collection cup limiting guide rail 510; a second drive motor 620, with its output shaft passing through the center of the positioning plate 610; a rotating rod 630 connected to the output shaft of the second drive motor 620; an outer sleeve 640 disposed on the side of the positioning plate 610 away from the second drive motor 620, and the axis of the outer sleeve 640 being parallel to the extending direction of the liquid collection cup limiting guide rail 510; an inner sleeve 650 fitted onto the inner wall of the outer sleeve 640 and sliding along the axial direction of the outer sleeve 640; and two sets of limiting blocks 660. The limiting block 660 is symmetrically arranged on the inner wall of the inner sleeve 650 along the axis of the inner sleeve 650; multiple arc-shaped guide rails 670 are provided, and the multiple arc-shaped guide rails 670 are spaced apart on the outer circumferential wall of the rotating rod 630 away from the second drive motor 620; wherein each arc-shaped guide rail 670 is inclined and spirally arranged on the outer circumferential wall of the rotating rod 630; the limiting block 660 abuts against the lower wall of the arc-shaped guide rail 670; the return spring 680 is sleeved on the outer circumferential wall of the rotating rod 630, with one end abutting against the surface of the positioning plate 610 and the other end abutting against the end wall of the inner sleeve 650.

[0047] In the above embodiment, the circulating lifting mechanism 600 is fixedly installed at the opening of the liquid collection cup limiting guide rail 510 by the positioning plate 610. In the initial state, the inner sleeve 650 is sleeved on the inner wall of the outer sleeve 640, the return spring 680 is in a natural extension and retraction state, the end of the inner sleeve 650 away from the positioning plate 610 abuts against the bottom of the liquid collection cup 532 that is stopped on the liquid collection cup limiting guide rail 510, and the two sets of limiting blocks 660 are symmetrically distributed along the axis of the inner sleeve 650 and their ends abut against the lower wall of the arc-shaped guide rail 670 on the outer circumferential wall of the rotating rod 630. When the assembly of the collection cup 532 and the capillary needle is required, and blood collection is performed, the second drive motor 620 starts, and its output shaft drives the rotating rod 630 to rotate synchronously. Since multiple arc-shaped guide rails 670 are spirally and inclinedly arranged on the outer circumference of the rotating rod 630, during the rotation of the rotating rod 630, the arc-shaped guide rails 670 generate axial thrust through their contact with the limiting block 660, pushing the limiting block 660 to cause the inner sleeve 650 to slide axially away from the positioning plate 610 along the outer sleeve 640. As the inner sleeve 650 slides, it simultaneously lifts the collection cup 532 it is in contact with, causing the opening of the collection cup 532 to move towards the capillary needle, and through the thrust, moving the capillary needle away from the blood collection point. One end of the collecting end is inserted into the opening of the collecting cup 532 to complete the assembly; then the inner sleeve 650 continues to lift the assembly and move it towards the collection hole 700. The capillary needle collection end passes through the collection hole 700 to pierce the fingertip and collects blood into the collecting cup 532 through capillary action; after collection, the second drive motor 620 reverses, the rotating rod 630 drives the arc-shaped guide rail 670 to rotate in the opposite direction, the axial thrust disappears, and the reset spring 680 pushes the inner sleeve 650 to return to its axial position along the outer sleeve 640 under its own elastic force. The inner sleeve 650 drives the collecting cup 532 and the capillary needle to return to their axial position and be pushed out of the box 100. Subsequently, the capillary needle is manually removed and discarded, and only the collecting cup 532 is sent for testing.

[0048] The spirally inclined arc-shaped guide rail 670, in conjunction with the symmetrically arranged limiting blocks 660, converts the rotational motion into a smooth axial linear motion of the inner sleeve 650, achieving uniform lifting of the collection cup 532. This prevents wobbling or offset during lifting, ensuring precise alignment and assembly of the collection cup 532 and the capillary needle, thus improving the reliability of component assembly. The two sets of limiting blocks 660 are symmetrically arranged along the axis of the inner sleeve 650, ensuring uniform force distribution and effectively guaranteeing the coaxiality of the inner sleeve 650 during sliding. This further enhances the assembly precision of the collection cup 532 and the capillary needle, preventing assembly failure or component damage due to uneven force. The outer sleeve 640 acts as a radial limiter for the sleeve, preventing the inner sleeve from... Radial offset occurs when the inner sleeve 650 slides, ensuring the stability of the lifting action. The reset spring 680 enables the automatic reset of the inner sleeve 650 without the need for additional drive components, simplifying the mechanism structure, reducing energy consumption, and improving the efficiency of cyclic lifting, allowing the device to quickly enter the next collection cycle. The entire cyclic lifting mechanism 600 is compact and highly efficient in transmission, forming a highly efficient synergy with the capillary needle automatic replenishment unit 400 and the collection cup 532 automatic replenishment unit 500, further improving the automated process of blood sample collection, significantly reducing the need for manual intervention, and ensuring the continuity of blood sample collection and sample quality through precise lifting and reset actions, adapting to the needs of large-scale, automated blood typing.
