Description

Technology Field

[0001] The present invention relates to a modular blood collection system with ensured deployment flexibility, and more specifically, to an automated blood collection system composed of a plurality of modular blood collection units that integrate functions for supplying blood collection tubes, labeling, blood collection, and specimen collection, configured to be arranged and connected in various ways according to the shape of a blood collection room in a hospital or medical institution. Background Technology

[0003] Blood collection rooms in hospitals and medical institutions are required to perform the entire process—from accurate labeling based on patient information, preparation of specimen tubes, and blood collection to specimen collection and transport—quickly and reliably. To meet these needs, centralized blood collection systems combining automated tube labeling devices, tube transport devices, and blood collection tables are being widely adopted recently.

[0004] Conventional centralized blood collection systems are structured to transport labeled tubes from a single large labeling device to a blood collection table, involving complex mechanisms such as multiple conveyor lines, stoppers, and pushers between the devices. However, such systems harbor various structural limitations. Since functions are distributed across different devices, the transport distance from the supply to the collection of blood collection tubes becomes long, resulting in delays in preparation time and a decrease in processing speed. Furthermore, because each module is collectively connected via conveyor lines, an error in any single device can cause the entire system to shut down.

[0005] Furthermore, since these systems are designed based on a linear layout, they lack placement flexibility in blood collection rooms with limited space or in irregularly shaped areas, inevitably restricting installation and operation. Additionally, even if situations such as increased blood volume or specific function failures occur, it is difficult to respond to those specific functions independently, which tends to increase the overall inefficiency of the system.

[0006] As such, although conventional technology provides automation and consistent processing, various problems may arise in actual operating environments due to a lack of spatial flexibility, difficulties in responding to failures, and limitations in scalability. Against this backdrop, there is a need to develop a blood collection system in which each blood collection unit independently includes a tube supply unit, a labeling unit, a blood collection unit, and a collection unit, and in which the system can be arranged and connected in various forms while each unit can operate stably. The problem to be solved

[0008] The objective of the present invention is to provide a modular blood collection system with ensured deployment flexibility, which allows for flexible placement and connection according to the structure of a blood collection room in a hospital or medical institution, while enabling each unit to operate independently and integrally perform an automated blood collection process.

[0009] More specifically, the purpose is to implement a structure in which the functions of supplying blood collection tubes, labeling, blood collection, and sample collection are integrated within a single modular blood collection unit, and multiple modular blood collection units can be connected and expanded in various forms such as straight, L-shaped, or U-shaped as needed, and each unit operates under independent control of power and data signals so that the operation of the entire system is not interrupted even if a specific unit malfunctions.

[0010] In addition, another objective is to provide a system that overcomes the complex conveyor structure and scalability limitations of existing centralized blood collection systems by including an automatic transfer structure for the collection unit positioned below the blood collection unit, a stacked supply slot for the tube supply unit, and an automatic label printing and attachment mechanism, thereby simultaneously ensuring flexibility and stability in installation and operation and efficiency in maintenance.

[0012] The technical problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art to which the present invention belongs from the description below. means of solving the problem

[0014] As an embodiment for achieving the above technical objective, the present invention provides a modular blood collection system comprising a plurality of modular blood collection units. Each modular blood collection unit includes a tube supply unit that stores and sequentially supplies blood collection tubes, a labeling unit that automatically attaches a label according to patient identification information to the supplied tubes, a blood collection unit that performs a blood collection operation using the labeled tubes, and a collection unit that automatically collects the tubes after blood collection is completed. These components are formed as an integrated structure so that each unit can independently perform blood collection preparation and processing.

[0015] As another embodiment for achieving the above technical problem, the modular blood collection unit additionally includes a connection part formed to enable connection with other units, and the plurality of units are configured to be arranged and interconnected in various forms such as straight, L-shaped, or U-shaped, so as to be able to flexibly respond according to the structure of the blood collection room.

[0016] In addition, the collection unit includes a transfer conveyor positioned below the blood collection unit to automatically transfer the tubes after blood collection is completed to the collection unit, thereby ensuring both hygiene and work efficiency of the blood collection space, and the tube supply unit includes a supply slot that stores multiple blood collection tubes in a vertical or inclined stacked structure, thereby allowing the tubes to be discharged sequentially, thus automating the blood collection preparation process.

[0017] In addition, the modular blood collection unit is configured to enable independent control of power and data signals, ensuring that the remaining units can continue to operate even if a malfunction occurs in some units, thereby securing the stability and scalability of the entire system. Effects of the invention

[0019] The modular blood collection system with secured deployment flexibility according to the present invention can significantly improve overall operational efficiency, such as shortening the transfer distance between functions and reducing preparation time, by integrating a series of processes ranging from supplying blood collection tubes, labeling, blood collection, and sample collection into a single modular blood collection unit.

[0020] In addition, since multiple modular blood collection units are configured to be arranged and connected in various forms, the system can be flexibly configured in a straight, L-shape, U-shape, etc., depending on the spatial structure or operational purpose of the blood collection room, and can provide excellent space utilization and expandability.

[0021] In addition, since each modular blood collection unit is structured to independently control power and data signals, the remaining units can operate without interruption even if a malfunction occurs in some units, thereby providing high overall system stability and reliability.

[0022] In addition, features such as the automatic transfer function of the collection unit, the stacked supply structure of the tube supply unit, and the automatic attachment function of the labeling unit can realize the automation of the entire blood collection process, thereby contributing to reducing the burden on blood collection personnel and shortening patient waiting times.

[0023] Based on these configurations and effects, the present invention can provide a practical blood collection system suitable for various clinical environments while effectively resolving problems such as placement constraints, structural complexity, and vulnerability to failure associated with conventional centralized blood collection systems.

[0025] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the configuration of the invention described in the detailed description of the invention or the claims.

Specific details for implementing the invention

[0028] The present invention will be explained in more detail below with specific examples. However, the embodiments described below are provided as examples to ensure that the concept of the present invention is sufficiently conveyed to those skilled in the art.

[0029] Accordingly, the present invention is not limited to the embodiments presented below and may be embodied in other forms. The embodiments presented below are described merely to clarify the concept of the present invention and do not limit the present invention thereto.

[0031] The present invention relates to a modular blood collection system that automates the processes of supplying, labeling, blood collection, and collection of blood collection tubes, while ensuring deployment flexibility to flexibly respond to various spatial constraints in medical settings. More specifically, the invention is a technology based on multiple modular blood collection units in which a tube supply unit, a labeling unit, a blood collection unit, and a collection unit are integrated within a single structure, wherein each unit can operate independently, and multiple units can be connected as needed to form a system unit.

[0032] The modular blood collection unit according to the present invention can be formed as an integrated configuration in which each unit includes an automation function. Accordingly, medical personnel can handle all processes from blood collection preparation to the collection of completed specimens through a single unit, thereby ensuring both operational efficiency and accuracy. In addition, each modular blood collection unit can be configured to include a connection part to enable mechanical connection or electrical and data interoperability with other units. Through this, the entire system can operate independently without sharing functions between units and can be flexibly expanded or contracted as needed.

[0033] These structural features can effectively resolve issues associated with conventional centralized blood collection systems, such as space utilization constraints, complex transfer line configurations, and the shutdown of the entire system in the event of a single failure. Furthermore, by arranging units in a straight, L-shape, or U-shape depending on the spatial structure of the blood collection room, optimal movement paths and blood collection environments can be achieved even in limited spaces. Since each unit can operate with separate power and signal control, system stability can be enhanced and maintenance efficiency improved.

[0035] As described above, the modular blood collection system according to the present invention is composed of a plurality of modular blood collection units, and each unit may be formed with an integrated structure including a tube supply unit, a labeling unit, a blood collection unit, and a collection unit so as to independently perform the main functions required for blood collection.

[0036] As illustrated in FIG. 1, such a configuration can be implemented in a form in which a tube supply unit (tube supply device), a labeling unit (barcode labeler), a blood collection unit (blood collection table), and a collection unit (conveyor unit) are integrated within a single unit. Each component can be arranged chronologically along the internal space of the unit in a functional order to enable continuous blood collection operations. Additionally, the modular blood collection system of the present invention may include a monitoring device (500) equipped with a sequence display function or a monitor for medical personnel.

[0038] Below, we will examine each unit constituting the modular blood collection unit of the present invention in more detail.

[0040] The tube supply unit (100) is a module that performs the role of stably storing and sequentially supplying blood collection tubes during the blood collection preparation stage, and can be configured as shown in FIG. 3 as an example.

[0041] Specifically, the tube supply unit (100) of the present invention may be formed to include a vertical or inclined stacked supply slot so as to stack and store a plurality of blood collection tubes in tube cassette units. The supply slot is provided with tube receiving grooves arranged at regular intervals so that each tube can be seated independently, thereby preventing interference with adjacent tubes or inclined movement.

[0042] It is preferable that the tube transfer line (120) be located at the top of the slot for smooth error handling.

[0043] A transparent cover may be provided on the upper part of the slot, and this cover may be made of a material having transparency and impact resistance, such as acrylic or polycarbonate. Through the transparent cover, the user can directly check the quantity of remaining tubes from the outside, and the cover can be opened and closed with a hinge structure or a slide structure, making it easy to replenish, clean, or disinfect the tubes.

[0044] Additionally, guide walls or ribs may be formed on the inner walls of the slots to prevent shaking or abnormal tilting during the stacking process. The guide walls may partially include pads made of elastic material, allowing for stable accommodation even when tubes with different outer diameters are stored. Tube cassettes can be manufactured in standardized sizes and may include compartmentalized units, such as 6 or 12 zones. The structure of these tube cassette units can be applied to both methods of loading empty tubes in bulk into baskets installed in the slots and methods of replacing dedicated cassettes pre-loaded with tubes. In particular, identification marks such as QR codes or barcodes can be attached to each tube cassette to enable lot-by-lot tracking, and thanks to the structure compartmentalized into fixed units, tube clumping or collapse that may occur during the stacking process can be effectively prevented.

[0045] The tube can naturally fall from the bottom of the supply slot by gravity, and in some cases, a low-torque roller or an inclined slide may be provided to allow the tube to move stably to the bottom discharge port at a constant speed. The discharge port can be positioned to be directly linked to the label attachment area in front of the labeling section, thereby allowing the discharged tube to be accurately delivered to the labeling location without a separate transfer process.

[0046] In the process of transferring the tube to the labeling section, a small belt structure or a horizontal / incised slide may be used, and guide rails or stoppers may be placed to maintain a constant direction and speed of movement of the tube. Additionally, at the location where the label is attached, a positioning pin or stopper may be provided to accurately stop the tube, so that the label can be stably attached in a constant circumferential direction.

[0047] The direct linkage structure between the discharge port and the labeling unit minimizes the movement path between supply and labeling, thereby reducing system complexity and preventing errors or blockages during the tube transfer process. Furthermore, compared to conventional methods involving long connections to a centralized labeler, this structure offers the advantage of shortening preparation time and improving on-site immediacy.

[0048] The tube supply unit described above may be equipped with a sensing device for monitoring the quantity of remaining tubes. For example, a detection unit, such as an optical sensor, a limit switch, or a load cell, may be installed at a specific location in the supply slot to detect when the number of remaining tubes falls below a predetermined number. Such sensor signals may be transmitted to a control unit to provide a warning indication on the user interface, or may be output as a supply request signal in conjunction with a hospital information system (HIS).

[0049] In addition, identification marks such as QR codes or barcodes can be attached to the tube cassettes themselves, enabling management based on specific lots or production dates. This allows tracking of the source and batch history of tubes used during the sample collection process, and, if necessary, enables the rapid identification and recall of the entire lot of tubes where a problem occurred.

[0050] The sensing and remaining quantity management functions can be performed in parallel with the operator's direct visual inspection via a transparent acrylic case applied to the exterior of the supply tube cassette. By providing both manual inspection and automatic monitoring, this prevents work delays caused by missed supplies or tube shortages. Unlike conventional simple storage structures, this feature can significantly improve on-site operational stability and patient response speed through automated monitoring.

[0052] The tube discharged from the tube supply unit can be directly guided to the label attachment area of ​​the labeling unit (200), and the labeling unit (200) can minimize identification errors immediately before blood collection by receiving and verifying patient identification information and test order information, and then immediately printing and attaching a barcode label to the outer circumference of the tube. At this time, the labeling unit is mechanically positioned adjacent to the supply unit so that it can be precisely stopped at the labeling location without separate long-distance transport, and by transferring the tube with the label attached to the blood collection unit, the entire process of preparation, labeling, and blood collection can be continuously processed within a single table.

[0053] As illustrated in FIGS. 2 and 3, the labeling unit (200) of the present invention may be placed inside the front cover (11), and may include a small label printer at the top and an automatic attachment module at the bottom that wraps and attaches the label to the tube.

[0054] The labeling unit is configured to communicate with a hospital information system (HIS) or a laboratory information system (LIS) and can receive metadata such as patient identification information, test items, priority (whether STAT is active), and time of blood collection in real time. The system can apply a standardized message format and, in the event of a network failure, can temporarily store the order queue using a local cache and synchronize it after the connection is restored. Additionally, the labeling unit can perform patient matching through at least one of scanning the barcode or QR code on the patient wristband, the call number of the reception kiosk, and the order ID within the electronic medical record (EMR), and can assign a hash-based one-time token to prevent duplicate output for the same patient and the same order.

[0055] The received data can be mapped to a label template, which can automatically adjust character size, barcode symbology (e.g., Code128, QR), label length, and margins in correspondence with the tube outer diameter and printable area. The label content may be configured to include a patient identifier (MRN), order ID, test code, priority, scheduled time of blood collection, operator identifier, unit identifier, and / or a verification checksum; to minimize the exposure of personal information, the patient name may be displayed with partial masking. For urgent (STAT) orders, visual emphasis elements may be applied to the template to improve identifiability at the blood collection station.

[0056] In the pre-label printing stage, the system can compare the wristband scan results with the patient key in the order database for double-checking of patient matching, and if they do not match, it can generate an alarm to block printing. After printing, a verification scan procedure may be performed immediately before or after attachment, and if a scan failure or print quality degradation is detected, automatic reprinting may be triggered. When reprinting, the status of the original order is updated to “reissued,” and a log may be recorded to enable history tracking.

[0057] The labeling unit can manage multiple orders on a queue basis, and the matching of tube specifications in the tube cassette mounted in the supply slot with the label template specifications can be verified in advance. If a specification mismatch is anticipated, the system moves the relevant order to a hold state and can guide the operator to replace the tube cassette or switch the template. Additionally, if multiple different test items are assigned to the same patient, scheduling can be performed to enable continuous labeling through order batch output.

[0058] In terms of security, communication between the labeling unit and the upper system may be conducted via an encrypted channel, and operator authentication may be restricted to account / password or card / tag-based two-factor authentication. All print, verification, and reissue events may be stored in an audit log along with timestamps, unit IDs, and operator IDs, and, if necessary, transmitted to a central server for future auditing and quality control. In environments with unstable networks, time synchronization may be performed periodically to correct for local clock drift.

[0059] Unlike centralized labeling facilities, this information integration configuration enables immediate data reception and label issuance at locations adjacent to the patient, thereby reducing preparation waiting times. Furthermore, it prevents errors caused by misidentification of patients through a double-check procedure based on wristband scanning and order comparison, and significantly reduces post-processing errors resulting from labeling defects through reissue history management and print quality verification procedures.

[0060] The labeling unit may include various mechanisms for reliably attaching a printed label to the outer surface of a blood collection tube. Label attachment can generally be performed while aligned circumferentially according to the outer diameter of the tube, and for this purpose, the labeling unit may be equipped with driving elements such as a rotary roller, a clamping arm, or an air suction pad.

[0061] In the case of the rotary roller method, the label can be uniformly attached across the entire circumference by rotating the tube while applying pressure to the surface of the tube to be labeled. In the case of the clamping arm method, the clamping arm, which holds the label, contacts the outer wall of the tube and compresses it from both sides, preventing the label from lifting or becoming eccentric. When using an air suction pad, attachment is possible in a non-contact manner by temporarily fixing the label to the suction pad and then spraying compressed air to adhere it to the tube surface.

[0062] Guide grooves or positioning pins for alignment may be provided at the labeling position, and the label's horizontality and attachment angle can be maintained consistently by attaching the label while the tube is stopped at this position. Immediately after attaching the label, a light squeeze roller operates subsequently to further stabilize the label's adhesive strength and minimize the formation of air bubbles or curling of the label.

[0063] In addition, a barcode scanner can be placed in the labeling unit immediately after label attachment, allowing for real-time verification of print quality and attachment status. If the verification results indicate that the barcode recognition rate falls below a certain standard or that the label is attached abnormally, the system can immediately perform reprinting and reattachment procedures. This reprinting function can prevent sample identification errors caused by defective labels and significantly reduce the risk of patient samples being rejected due to improper labels.

[0064] Unlike the method of batch labeling trays from a central labeler and then moving them, this attachment mechanism allows for the immediate attachment of labels to individual tubes at the patient table, thereby shortening the preparation time immediately before blood collection. Furthermore, the structural flexibility that allows for various attachment methods offers the advantage of selecting the optimal attachment mechanism tailored to the installation environment and blood collection tube specifications of each medical institution.

[0065] The labeling unit of the present invention can be designed with both ease of maintenance and safety in mind to ensure stable operation over a long period of time. First, the label printer and the label attachment module can be configured to be easily accessible through a front cover, and the cover can be designed with a hinged or one-touch structure so that it can be opened and closed without tools. This allows the user to quickly perform label roll replacement, cartridge cleaning, or attachment module inspection.

[0066] The labeling unit may be equipped with sensors to detect abnormal situations such as label cutting errors, improper transport, or attachment failures. For example, if a label is not transported properly, an optical sensor can detect this, stop the device's operation, and emit a warning sound; similarly, if a label is torn or double-fed, the system can be stopped immediately upon detection. Such safety devices can prevent defective labels from being attached to patient tubes and minimize the burden of rework on operators and the possibility of sample errors.

[0067] In addition, an emergency stop switch may be installed in the labeling section, allowing the user to immediately stop the operation of the device in the event of an emergency. A safety interlock function may be provided so that the device can automatically stop if the user's hand or clothing gets caught in the label conveyor during operation, or if unexpected foreign matter enters during the tube supply process.

[0068] The label printer and attachment module can be designed to be modular, allowing for separation and replacement. In the event of a malfunction, only the affected module can be replaced, enabling rapid recovery without shutting down the entire equipment for an extended period. This modular design can reduce maintenance costs, and securing spare modules can maximize uptime in hospital environments.

[0069] Such maintenance and safety design can significantly enhance the reliability of the entire system by improving field accessibility compared to conventional standalone labelers and enabling immediate response in the event of errors.

[0071] As previously explained, the tube discharged from the tube supply unit is directly guided to the label attachment area of ​​the labeling unit and can be provided at the location immediately before blood collection with patient identification information attached. The labeled tube is transferred to the blood collection unit through the labeling tube discharge unit (210) and can be used immediately in the work area of ​​the blood collection unit; after blood collection is completed, it is transferred to the lower transfer structure through the transfer input port (310) and can be automatically transferred to the collection unit. Due to such adjacent arrangement and continuous movement paths, the entire process of preparation, labeling, blood collection, and retrieval can be performed continuously within a single table.

[0072] The blood collection unit (300) is a physical workspace for medical personnel to collect a patient's blood, and may be configured to include a table structure placed at the front of the modular blood collection unit.

[0073] For example, as illustrated in FIG. 4, the table structure of the blood collection unit (300) of the present invention may have an asymmetric layout divided into a patient area (320) and a medical staff area (330), and each area may be designed with different widths, depths, and heights considering the user's movement characteristics and frequency of access. For instance, the patient area (320) may be formed to have a straight or gently curved edge profile to be advantageous for arm placement and trunk support, and the medical staff area (330) may have a relatively wide effective working width and a planar structure considering cable / consumable movement paths to be advantageous for label verification, instrument placement, or keyboard work.

[0074] Level differences or material boundaries may be formed between each area for visual and physical separation. To reduce cross-contamination, the front edge where the patient's arm rests is rounded to simultaneously alleviate pressure and local slippage upon skin contact. On the front side facing the medical staff, mounting rails for attaching accessories, such as a label verification indicator, a small tray, and / or a disinfectant holder, may be provided. Additionally, an overhang structure may be formed at the bottom to secure knee and foot space. To accommodate blood collection from either the left or right arm, the table corners may include symmetrical armrest shapes, or the fastening parts may be designed with a symmetrical structure to allow for the left-right rotation of the module. In environments requiring privacy, a partition may be additionally installed on the rear or side of the tabletop, and the partition may be made of a material that is easy to clean and replace.

[0075] The top plate of the blood collection unit may be formed with the patient area and the medical staff area at different heights. For example, the patient area may be set to a height of 730 to 850 mm, more preferably 780 to 850 mm, so that the patient can rest their arm comfortably.

[0076] If the height is less than 780mm, an average adult patient may have to excessively bend their upper body to rest their arm, which can cause discomfort and tension, and reduce the positional stability of the arm vein during blood collection. Conversely, if it exceeds 850mm, the patient may have to raise their shoulder or excessively extend their elbow, leading to increased muscle tension and fine motor strain, which can cause discomfort. In this case, it is more desirable to have a height of 780mm or more to ensure a height difference from the medical staff area.

[0077] The medical staff area can be set within a range of 650 to 740 mm, taking into account visibility and accessibility to instruments. In this case, it is desirable for the height of the medical staff area to be relatively lower than that of the patient area.

[0078] If it is less than 650mm, equipment accessibility actually decreases, and fatigue increases during long-term work because the waist must be bent excessively. Conversely, if it exceeds 740mm, the height of the patient area and the field of view become similar, which may result in a narrowed space for the wrist and instrument manipulation during blood collection and make it difficult to secure a clear view.

[0079] The patient's arm rest can be formed to have a gentle curvature corresponding to the flexion of the forearm, and can suppress fine movements during blood collection by maintaining the surface friction coefficient within an appropriate range. The effective length of the arm rest in the anterior and posterior directions can be set to a range that prevents excessive extension or flexion of the shoulder and elbow angles in various body types, and may include a detachable pad or height-correcting wedge if necessary.

[0080] The medical staff area described above may be configured so that a main tray and consumable holder are positioned within reach, allowing items such as blood collection needles, gauze, tape, labels, and scanners to be placed within the work path. The front edge of the top plate may be rounded to facilitate wrist support and may include a local pressure distribution shape to relieve compression of the radius / ulna during prolonged work. To ensure visibility, the medical staff area may be maintained lower than the patient area, and a retraction space for the knees and feet is secured beneath the top plate to minimize forward bending of the upper body when approaching from the front. The armrests and equipment placement may be designed with a symmetrical or switchable structure to maintain the same body angle even when switching between left and right blood collection, and if necessary, a specific area of ​​the top plate may include a hinge or ratchet mechanism to allow for angle adjustment.

[0081] Finally, the joint between the top plate corners and the module housing can reduce skin scratching and contamination through obtuse rounding and minimized step difference treatment. This ergonomic design ensures both patient postural stability and medical staff accessibility, while reducing fatigue accumulation and operational errors caused by repetitive movements.

[0082] The top plate of the blood collection unit serves as the primary work surface in contact with both the patient and medical staff; it can be designed to simultaneously consider hygiene, durability, and psychological comfort. The patient-side plate may feature wood materials or cushion pads to alleviate psychological tension during the blood collection process. Wood materials can reduce patient anxiety by providing a warm tactile sensation, while cushion pads distribute local pressure on the area where the arm rests, offering comfort even during prolonged blood collection. These materials are designed to be detachable when necessary, allowing for easy disinfection or replacement.

[0083] The tabletop facing the medical staff can be formed from hygienic materials such as white ceramic. Ceramic materials possess excellent chemical and scratch resistance, ensuring that deformation or discoloration does not occur even when using various disinfectants such as alcohol or hypochlorous acid. Furthermore, due to its smooth surface and low absorption rate, contamination can be easily removed even if it comes into contact with blood, bodily fluids, or reagents. The ceramic tabletop has a consistent thickness and weight, preventing shaking during work and providing stable support for medical staff when attaching labels or handling instruments.

[0084] As described above, the top surfaces on the patient side and the medical staff side can be constructed using different materials, thereby enabling the blood collection area to simultaneously provide psychological comfort for the patient and a hygienic and professional working environment for the medical staff. Furthermore, the dual-material structure intuitively distinguishes the characteristics of each area, allowing both the patient and the medical staff to utilize the space without confusion.

[0085] The blood collection unit of the present invention may include various additional functions and convenience devices to increase the work efficiency of patients and medical staff. For example, a separate storage space (340) capable of storing a keyboard, wireless input device, label scanner, consumable storage box, etc. may be provided at the bottom of the pathologist's area. This storage space (340) may be implemented as a drawer or sliding door type, so that equipment can be taken out and used immediately when needed, and after use, it can be stored in a sealed state to prevent external contamination.

[0086] In addition, a dedicated caster (350) that is height-adjustable can be installed at the bottom of the blood collection unit to ensure mobility and ease of installation. The dedicated caster includes both a fixed function and a rotating function, allowing the blood collection table to be easily moved and then stably fixed at a desired position. The height adjustment function allows the table height to be flexibly adjusted to suit various patient heights and medical staff working postures, thereby reducing musculoskeletal fatigue that may occur during prolonged use.

[0087] In addition, the blood collection unit may be equipped with a queue indicator, an LED indicator showing the work status, or a stand holder capable of mounting a medical monitor, thereby supporting patient waiting management and the workflow of medical staff. If necessary, a consumable holder, such as a hand sanitizer dispenser and a gauze and tape holder, may be added to the front of the blood collection unit, enabling the rapid performance of necessary procedures immediately before and after blood collection.

[0088] In addition to supporting blood collection, which is the basic function of the blood collection unit, these additional functions and convenience devices can simultaneously enhance the convenience of patients and medical staff, maximize equipment utilization, and increase the operational efficiency of the entire system.

[0090] Tubes from which blood collection is completed at the blood collection unit can be immediately transferred to the collection unit (400) and automatically retrieved. Patients or medical staff do not need to store or move the tubes in a separate container immediately after blood collection, and can immediately transfer them to the collection line through an input port provided on the front or side of the blood collection unit. This structure, in which the blood collection unit and the collection unit (400) are integrated, can shorten the sample transport step after the blood collection process and significantly reduce the possibility of sample loss, contamination, or delay.

[0091] An inlet for inserting a tube that has completed blood collection may be provided at the front end of the collection unit (400). The inlet may be formed on the side or part of the top plate of the blood collection unit table so that a patient or medical staff can easily insert the tube, and may have a circular or elliptical inlet shape. The inner diameter of the inlet may be designed to minimize the gap with the outer diameter of the tube, thereby preventing damage caused by shaking or rotation during the insertion process. The edge of the inlet may be curved or rounded to reduce damage caused by impact during insertion, and the surface may be treated with an antibacterial coating or scratch-resistant treatment to maintain hygiene and durability even with repeated use.

[0092] Guide grooves or inclined plates may be formed inside the input port to allow the tube to fall stably in a consistent direction. The guide grooves maintain the tube's axial direction consistently, enabling accurate alignment upon entry into the conveyor, while the inclined plates act as a cushion to prevent impact if the tube falls at excessive speed. Additionally, shock-absorbing pads may be placed at specific locations inside to prevent micro-cracks or label damage that may occur during the fall.

[0093] After passing through the input port, the tube can be guided to an initial conveying section, which is formed as a horizontal or gently inclined passage to allow the tube to settle smoothly onto the lower conveyor. The initial conveying section may not only have a fixed structure but may also be equipped with a motor that applies micro-vibrations as needed, thereby guiding multiple tubes to maintain natural spacing and alignment even when fed simultaneously. Additionally, the conveying section may be equipped with a rotating brush or a spacing brush to prevent the tubes from adhering closely to each other or tilting, and to assist in alignment by ensuring that the input direction and orientation are maintained uniformly.

[0094] This initial transport structure ensures that tubes with completed blood collection can stably enter the collection line, enabling rapid processing without tube collision, breakage, or label damage, especially in environments where a large number of patients undergo blood collection continuously. Furthermore, by guaranteeing alignment at the initial stage, the risk of blockage or loss during subsequent conveyor transport can be significantly reduced.

[0095] The tube delivered through the input port and the initial transfer section can be automatically moved to a central collection point via a transfer conveyor (410), which is a key element of the collection unit. The transfer conveyor can be arranged along the lower part of the modular blood collection unit, and when multiple units are connected, the lower conveyors of each unit can be continuously connected to form a single line.

[0096] As shown in FIG. 4, the transfer conveyor (410) can be designed with a width that is expanded to a range of approximately 120 mm to 170 mm, unlike a typical narrow structure. This prevents the tubes from overlapping or becoming crowded even when multiple tubes are fed simultaneously, and allows individual tubes to be transported stably while maintaining spacing. Additionally, the surface of the transfer conveyor is made of a material with an optimized friction coefficient, which can suppress the tubes from shaking or tipping over excessively.

[0097] Specifically, if the width is narrowed to less than 120mm, the tubes must be arranged in a single line, which frequently causes interference between tubes at the moment of insertion and increases the likelihood of transport errors and tube breakage due to rotation and overlapping. Additionally, there is a high risk that the tube will deviate from the rail if an error in the position of the input port occurs. Conversely, if the width exceeds 170mm, the spacing between tubes inside the conveyor becomes excessive, reducing the precision of sensor detection and potentially causing irregular shaking as the tubes fail to be fixed in place during transport. Furthermore, expanding the width leads to an increase in the overall installation space of the device, which can reduce the compactness of the modular structure.

[0098] Meanwhile, guide rails or guide grooves may be provided on both sides of the conveyor to assist in the alignment of the tubes. Guide rails can prevent the tubes from shifting to one side or tipping over during transport, while guide grooves can enhance stability by guiding the bottom of the tubes to move along a specific track. In addition, a spacing device or a brush structure may be installed on the upper part of the conveyor, allowing multiple tubes to move while maintaining a natural spacing even when fed simultaneously. The brush can absorb the impact generated as the tubes are pushed forward and simultaneously correct the orientation of the tubes.

[0099] In addition, ribs at predetermined intervals or fine vibration generating devices may be placed in certain sections of the transfer conveyor, allowing the tube to move naturally while aligned even when it enters tilted according to the label direction. This alignment mechanism can have the effect of increasing the label recognition rate of the sample and minimizing errors in subsequent processing.

[0100] The transfer conveyors can be arranged in various forms between modules, such as straight lines, L-shapes, or U-shapes, allowing for flexible configuration to suit the constraints of hospital space. Even when multiple modules are connected, the transfer conveyor line can be designed to continue uninterruptedly so that all tubes converge at a central collection point.

[0101] Unlike conventional simple drop or narrow-width conveyor structures, this conveyor design and alignment mechanism can ensure stable transport without clogging, tipping, or loss even in environments where a large volume of tubes are continuously fed, and can simultaneously improve sample processing speed and quality.

[0102] Meanwhile, although the blood collection completion tubes collected as described above may be collected individually, it is preferable to finally gather the blood collection completion tubes transported along the transport conveyor at a central collection point. The central collection point is located at the end of a transport conveyor line continuously connected from multiple modular blood collection units and can be directly linked to a specimen reception room or an analysis pre-processing area within the hospital.

[0103] The central collection point can be designed to go beyond simply collecting tubes and maximize the efficiency of specimen sorting and aggregation. For example, aggregation trays or automatic sorting slots can be placed at the terminals, allowing tubes to be separated and stored according to patient ID, test items, or priority. If necessary, barcode scanners or RFID readers can be installed to automatically record the arrival time and label information of collected tubes and update them in real-time to the upper-level system (HIS / LIS).

[0104] In addition, the central collection point can be equipped with a shock-absorbing structure. The end of the transfer conveyor is equipped with a cushioning pad or an angle-absorbing flap, allowing the tube to stop stably without impact even when it reaches the end while moving at a constant speed. This prevents label damage or the formation of bubbles in the blood sample.

[0105] The central collection point can secure a large accumulation space to simultaneously process tubes flowing in from multiple modules, and may include an automatic discharge line or a double tray structure to prevent overcrowding. This allows the next tray to be automatically positioned when one tray is full, thereby enabling continuous operation.

[0106] In addition, the central collection point may be equipped with a standardized interface to enable integration with analysis equipment or automated receiving devices in the future. For example, it may adopt standard specifications that allow a robotic arm to directly pick up collection trays, or be designed to connect directly to an automated pre-processing line within the analysis room.

[0107] Unlike conventional individual table storage or manual transport methods, such a central collection point aggregation structure enables the efficient collection of multiple patient specimens and allows for tracking and management without loss or omission, while also significantly improving the specimen processing speed of the entire hospital by integrating with automated equipment.

[0109] Previously, the process of stably collecting samples through the transport flow from the collection unit to the central collection point was explained. In the subsequent section on connection and networking, a structure is described in detail in which multiple modular blood collection units are mechanically and electrically connected in a continuous manner, enabling all units to operate while maintaining the same quality and stability.

[0110] In particular, the modular blood collection unit of the present invention may be configured to include a front top plate, a lower frame, left and right side end caps, and a rear service bay, and the connection part may be designed considering the structural characteristics of such modules.

[0111] Specifically, the modular blood collection unit of the present invention may include mechanical and electrical connection parts so that a plurality of modules can be connected to each other. Alignment guides and fasteners may be disposed on the left and right side end caps of each module.

[0112] The shape of the connecting part of the present invention is not significantly limited, but as an example, a three-level connection point may be provided so that the upper table unit, the lower frame, and the conveyor continuous connecting part can each be independently aligned and connected.

[0113] Specifically, the joint point of the upper table unit may include a tapered centering pin and a dovetail guide to maintain the flatness and level difference of the top plate at 1 mm or less, and the joint point of the lower frame may include an elastomer anti-vibration pad and a slot fastening part to reduce vibration transmission and allow for fine gap adjustment.

[0114] The mechanical connection may include guide rails, docking slots, or sliding fasteners to allow adjacent modules to be physically joined, and may be configured to enable rapid fastening and unfastening without tools. In this case, a fail-safe structure may be applied to the fastening part, and a double stop latch may be provided to prevent the module from detaching even in a partially fastened state, and the completion of fastening may be detected by a mechanical indicator or a proximity sensor. A round edge cover to prevent finger pinching and a sealing gasket to reduce liquid penetration may be added to the outer periphery of the joint between modules. Additionally, a micro-leveling foot (adjustable ±10~20mm) may be provided on the bottom of each module to align height and parallelism.

[0115] The top plate joint can be covered with a bridge cap after adjustment to minimize steps and gaps, and prevent a patient's arm or tool from getting caught. In the forward and backward directions of the module, an anti-tip bracket can be fastened to a floor anchor, thereby reducing the risk of tipping over when external forces are applied.

[0116] For continuous connection of the conveyor, belt linkage couplers may be placed at both ends of the lower frame of each module. For straight connection, a transfer plate or nose bar (small diameter idler) with a very small gap (e.g., 2 to 3 mm) may be applied to prevent the tube from getting stuck in the transfer gap, and the speed and tension between modules may be synchronously controlled using encoder feedback.

[0117] In addition, a corner bridge module may be provided for L-shaped or U-shaped arrangements, and the corner bridge may include a curved belt / idler assembly to maintain a radius of curvature greater than a predetermined value to prevent tube overturning or label damage. A jam detection sensor and an emergency guide brush are positioned on the upper part of the conveyor joint to immediately stop the line and restore alignment in the event of an unexpected overlap.

[0118] The electrical connection may be configured as a hybrid connector that includes both power lines and data communication lines. The connector may include a keying structure and a blind mate guide to prevent misinsertion, and the contacts may be coated with corrosion-resistant plating. For safety, a soft-start circuit may be applied to limit inrush current upon energization, and an interlock switch may be included to prevent operation unless the connector is fully locked. Communication may be implemented via Ethernet or fieldbus and may be wired in either a daisy-chain or hub-type star topology between modules. Power and data cables may be housed in a cable tray / strain relief along the rear service bay and designed to be accessible via a quick-release panel for cleaning and maintenance.

[0119] Considering a non-linear arrangement, the left and right end caps may have a symmetrical port arrangement, and the fastening part may be designed with a mirror structure to allow the module to be installed in a left-right orientation if necessary. In addition to 90-degree rotation, the corner bridge module can be adjusted to a predetermined angle according to site constraints and may include an offset adjustment guide to avoid interference with walls or columns. Corner top caps are provided so that the outer line of the upper table matches the curvature of the corner bridge, ensuring a continuous appearance and ease of cleaning.

[0120] In terms of safety, the Emergency Stop (E-STOP) of all modules is serially linked via an NC loop, allowing the entire line to be safely stopped even if an operation occurs at any single point, and the drive unit can immediately cut off power through the Safe Torque Off (STO) function. The conveyor automatically stops when a module is separated, and a software-based safety state can be applied to prevent restarting when the connector is disconnected. Additionally, since the area around the connection may be exposed to cleaning agents and bodily fluids, the exterior material can be selected to have IP-rated sealing and chemical resistance.

[0121] The installation and expansion procedure can be performed in the following order: placing the module, aligning the height using leveling feet, completing mechanical fastening, engaging the conveyor coupler, and verifying alignment with a gap gauge. Subsequently, power and data connectors are connected, and once module ID recognition and the handshake are completed in the software, the line map can be automatically updated. This procedure can be applied identically when adding new modules or switching layouts, thereby enhancing on-site responsiveness.

[0122] With the intermodule connection structure configured in this way, each module can be flexibly arranged in a complex form including a straight line, an L-shape, or a U-shape as shown in FIG. 7, and mechanical alignment and power and data networking can be implemented in a short time. As a result, rapid installation and fault isolation are possible even in sites with significant space constraints, thereby improving the availability and maintainability of the entire system.

[0123] Meanwhile, each modular blood collection unit may be equipped with an independent power supply and control unit for operation. The power supply may be supplied separately on a module-by-module basis, allowing it to operate independently without affecting adjacent modules even if a power failure occurs in a specific module. The control unit may include a processor, memory, and a communication interface, and can monitor the status of each module in real time and control necessary operations.

[0124] Each module may be equipped with a status detection sensor that monitors temperature, current, motor status, or sensor values, and the control unit can determine whether a fault has occurred based on this. If an abnormality is detected, the corresponding module can be immediately switched to isolation mode; during this process, the conveyor line is automatically disconnected or a bypass path is established to ensure the continuous operation of the entire system.

[0125] Communication between modules can be achieved through a network with the central control unit, which can optimize the operation of the entire system by collecting and analyzing status data from each module. In the event of an anomaly in a specific module, the central control unit can immediately provide an alert to the operator, isolate the module in question, and simultaneously control the remaining modules to maintain normal operation.

[0126] In addition, modules can be designed to be replaceable via a hot-swap method. This means that a faulty module can be disconnected or replaced without shutting down the entire system, and when a new module is connected, power and data synchronization occurs automatically, allowing it to be immediately integrated into the system. This minimizes downtime for hospital operations.

[0127] Unlike conventional centralized control methods, this independent control and fault isolation structure can significantly improve the stability and reliability of the system by preventing the failure of a specific module from leading to the interruption of the entire line.

[0128] As such, each module can operate by being equipped with an independent power supply and control unit, and the network linked to HIS / LIS can be connected on a module-by-module basis. Even if a malfunction occurs in a specific module, the operation of other modules is not affected because the power and data signals are isolated. Through this independent control structure, not only is fault isolation possible, but rapid response is also possible without interrupting the entire system during future module expansion or replacement.

[0129] The modular blood collection unit of the present invention can be designed to have high scalability and ease of installation to cope with structural constraints of hospital space and fluctuations in workload. Since each module has an independent housing form, if the addition of a new module is required, it can be quickly connected simply by attaching it to the left or right side end caps of the existing module. At this time, since power and data are separated at the module level, new modules can be connected or faulty modules replaced without interrupting the entire system.

[0130] During installation, leveling can be easily achieved using the height-adjustable feet and casters provided on the bottom of each module, and stable support can be maintained even during prolonged use by applying floor fixing anchors. The joint between the module's top plate and bottom frame is designed with standardized dimensions, allowing for free switching between straight, L-shaped, or U-shaped layouts. For example, in a space-constrained outpatient blood collection room, the layout can be arranged in an L-shape or U-shape to optimize traffic flow, while in a large-scale laboratory, it can be expanded into a straight configuration to accommodate many patients simultaneously.

[0131] Scalability extends beyond simply increasing the number of modules; it enables the gradual expansion of system capacity to accommodate increases in the number of hospital patients or the diversification of examination items. In particular, when combined with independent control and fault isolation functions at the module level, the remaining modules can continue normal operation even if a specific module is undergoing inspection or replacement, thereby significantly improving the overall system uptime.

[0132] Due to these structural advantages, the modular blood collection system of the present invention can provide a hospital-friendly structure that minimizes initial installation costs while allowing for phased expansion as needed. Furthermore, installation and layout changes can be easily performed, enabling flexible adaptation to the spatial conditions and operational strategies of various medical institutions.

[0134] Due to the above-mentioned features, the modular blood collection system according to the present invention can achieve a significant improvement in preparation speed and loading capacity compared to the existing centralized type based on the same number of units.

[0135] Figure 6 is an example for measuring the effectiveness of the modular blood collection system of the present invention, and analyzes the preparation speed and loading capacity of the system of the present invention composed of 4 to 6 sets.

[0136] Specifically, when the existing system is configured with 4 sets, the preparation speed starts at approximately 1,500 tubes per hour and gradually decreases to 1,200 and 960 tubes / hour as the number of sets increases, whereas the system according to the present invention shows a tendency to increase proportionally to 2,000 tubes / hour based on 4 sets, 2,500 tubes / hour based on 5 sets, and 3,000 tubes / hour based on 6 sets. This difference in performance is due to the fact that the present invention has a structural basis in which blood collection preparation tasks can be performed in parallel, as each modular blood collection unit is designed with an independent functional execution structure.

[0137] In other words, the present invention integrates a tube supply unit, a labeling unit, a blood collection unit, and a collection unit into each unit and configures these units to independently repeat the same process, thereby enabling horizontal scalability as the preparation speed increases quantitatively with the number of units. This feature stems from the fact that, as illustrated in the process improvement model of FIG. 5, the bottleneck of the centralized supply → sequential operation method is eliminated and simultaneous operation at the unit level is possible; based on the above features, the module can be infinitely expanded as needed.

[0138] In addition, since the tube supply unit of the present invention has an individual storage space, the loading capacity can also increase linearly as the number of units increases. For example, as shown in the lower graph of FIG. 6, the present invention supports a loading capacity of 1,600 tubes when configured with 4 sets, 2,000 tubes when configured with 5 sets, and 2,400 tubes when configured with 6 sets, which shows a significant increase in loading capacity compared to the fixed capacity of 1,200 tubes of existing products.

[0140] Meanwhile, as illustrated in FIG. 8, the modular blood collection unit of the present invention may be formed such that some components are detachable. As an example, the front cover (11) and the blood collection unit (300) may be configured to be detachable. In this case, the front cover (11) can be attached or detached via a hinge or a one-touch fastener, and when released, it can directly access the internal transfer line or the input area. Such a detachable structure facilitates cleaning of residues such as blood, reagents, and disinfectants that may occur during the blood collection process, and has the advantage of allowing only the necessary parts to be quickly detached and replaced without disassembling the entire device during periodic maintenance. Accordingly, it is possible to minimize downtime of the equipment and improve maintenance efficiency, and it has a significant difference from the conventional integrated structure in that it allows for selective replacement of parts in addition to replacement of modules.

[0141] In addition, as illustrated in FIG. 9, the modular blood collection system of the present invention can be configured so that even if a problem occurs in a specific module while a plurality of modules are connected in series, only that module can be selectively removed or replaced. In this case, the remaining modules can continue to operate, thereby maintaining a stable blood collection process without interrupting the entire system. This structure can simultaneously improve availability and maintainability in actual operating environments by utilizing independent control and separability at the module level.

[0143] Due to these structural characteristics, the modular blood collection system of the present invention can reduce waiting times for blood collection in hospitals or medical institutions, enable continuous operation for multiple patients, and provide flexibility to immediately expand to mass processing when necessary. Therefore, the present invention can simultaneously improve operational efficiency and stability in actual clinical settings by eliminating bottlenecks caused by centralized supply and sequential operation methods and enabling simultaneous unit-based operations.

[0145] The embodiments of the present invention have been described above. The technical features are not limited thereto and include all variations that can be modified and applied by a person skilled in the art based on the technical concept of the present invention. Explanation of the symbols
