Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an automatic tube preparation machine. Background Technology

[0002] In clinical testing, the selection of blood collection tube types relies on manual experience (such as distinguishing between procoagulant and anticoagulant tubes based on the test items). This can easily lead to problems such as mismatch between tube type and test items (e.g., misusing EDTA tubes for coagulation testing) and mismatch between label information and patient identity (misaligned manual pasting, illegible handwriting). Moreover, manual tube preparation takes an average of 3-5 seconds per tube. Large hospitals with high daily processing volumes require 3-5 dedicated personnel for tube preparation, which increases fatigue and error rates due to the high workload, resulting in significant efficiency bottlenecks.

[0003] Existing automated blood collection tube preparation equipment generally only supports a single size of blood collection tube, lacking compatibility and unable to adapt to application scenarios with multiple sizes of blood collection tubes. Furthermore, it is slow and bulky. The construction of smart hospitals requires an automation coverage rate of ≥85% in the laboratory department, while the current automation rate of the tube preparation process is only 32% (China Medical Equipment Association 2023 report), becoming a key bottleneck to full-process automation.

[0068] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0069] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0070] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0071] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0072] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0073] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0074] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0075] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0076] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0077] Example

[0078] like Figures 1 to 3 The automatic tube preparation machine shown includes a tube storage mechanism 1, a material handling mechanism 2, a tube feeding mechanism 3, a labeling mechanism 4, a printing mechanism 5, a tray 6, a control circuit board 7, and a machine housing 8. The tube storage mechanism 1, the material handling mechanism 2, the tube feeding mechanism 3, the labeling mechanism 4, the printing mechanism 5, and the control circuit board 7 are all located inside the machine housing 8.

[0079] like Figure 4 and Figure 5The illustrated storage compartment mechanism 1 includes multiple vertically spaced storage compartments 13 arranged side-by-side. Specifically, the storage compartment mechanism includes a back plate 11, multiple partitions 12, and a cover plate 14. The back plate 11 is vertically arranged, and the multiple partitions 12 are vertically arranged parallel to each other on the back plate 11 and perpendicular to the back plate 11. The storage compartments 13 are formed between adjacent partitions 12. In this embodiment, there are seven storage compartments 13, supporting the storage of seven common blood collection tube types. Depending on the size of the blood collection tubes that each storage compartment 13 needs to accommodate, the lateral width of each storage compartment 13 (i.e., the spacing between adjacent partitions) can be the same or different.

[0080] A cover plate 14 is horizontally positioned above the partition plate 12, covering all or part of the top of all the tube compartments 13 along their depth direction. The cover plate 14 has a corresponding compartment identifier for each compartment. The compartment identifier is preferably a color identifier, with the identifier for each compartment 13 matching the color of the cap of the blood collection tube it stores. In this embodiment, the compartment identifier for each compartment 13 is an identifier block 15 matching the color of the cap of the blood collection tube it stores. In practical applications, the identifier block 15 can be the cap of the blood collection tube stored in each compartment 13. For example, if the third compartment contains blood collection tubes with red caps, then the identifier block 15 directly above the third compartment represents the red cap of that blood collection tube. In some other embodiments, the cover plate 14 is detachably connected to the partition plate 12, facilitating the opening of the top of the compartment 13 to add blood collection tubes; the partition plate 12 is also detachably connected to the back plate 11, facilitating the adjustment of the lateral width of the compartment 13 to accommodate future additions of new tube types.

[0081] like Figure 5 As shown, each compartment 13 has a protrusion 121 on the left side of its bottom, and the protrusion 121 is integrally formed on the partition 12.

[0082] like Figures 6 to 9 The material handling mechanism shown includes a contouring block 21 set at the bottom of the tube bin and a contouring block drive device for driving the contouring block 21 to rotate; the contouring block drive device can drive the contouring block 21 to rotate, forming a dynamic gate at the bottom of the tube bin 21; each tube bin 13 is provided with a dynamic gate formed by the contouring block 13 on its lower side.

[0083] Specifically, the contouring block 21 is positioned on the right side of the bottom of the tube compartment 13 along the depth direction of the tube compartment. The contouring block 13 has a contouring groove 211 on the side corresponding to the protrusion 121, forming a temporary storage position between the protrusion 121 and the contouring groove 211. The temporary storage position can only accommodate one blood collection tube 9. When the blood collection tube 9 is in the temporary storage position, it is pushed to the bottom of the tube compartment 13 when the contouring block 21 rotates. After the contouring block 21 is reset, another blood collection tube 9 enters the temporary storage position.

[0084] The contouring lever drive device includes a lever shaft 22, a lever fork 23, a return spring 24, a limit pin 25, a spring fixing pin 26, and a lever fork drive device 27.

[0085] like Figure 8 As shown, the contouring block 21 is located on the front side of the back plate 11, and the fork 23, return spring 24, limit pin 25, spring fixing pin 26 and fork drive device 27 are located on the rear side of the back plate 11; the block shaft 22 is connected to the rear end of the contouring block 21, and the back plate 11 is provided with a corresponding block shaft hole for the block shaft 22. The block shaft 22 passes through the block shaft hole and is fixedly connected to the vertically arranged fork 23.

[0086] like Figure 7 As shown, the limiting pin 25 and the spring fixing pin 26 are fixed on the back plate 11, located on the left side of the shift fork 23, with the limiting pin 25 above the shift block shaft 21 and the spring fixing pin 26 located to the lower left of the limiting pin 25. One end of the return spring 24 is connected to the spring fixing pin 26, and the other end is connected to the shift fork 23. In this embodiment, the shift fork 23 is provided with a shift fork hole 231, located on the shift fork 23 between the limiting pin 25 and the shift block shaft 22. The return spring 24 is horizontally arranged, with one end connected to the spring fixing pin 26 and the other end connected to the shift fork hole 231, so that the upper end of the shift fork 23 abuts against the limiting pin 25. Each tube compartment 13's contoured shift block 21 is correspondingly provided with the aforementioned shift block shaft 22, shift fork 23, return spring 24, limiting pin 25, and spring fixing pin 26. It should be noted that, in this embodiment, the front end of the contouring block 21 of each tube compartment 13 is provided with a front end block shaft, which is disposed on the contouring block fixing plate to increase the stability of the contouring block 21 during rotation (e.g., Figure 1 As shown, the unlabeled contour-following block fixing plate.

[0087] The shift fork drive device 27 is an electromagnet, equipped with a retractable shift lever 271, which can reciprocate horizontally on the rear side of the back plate 11. Specifically, as shown... Figure 7 As shown, during the movement of the shift fork drive device 27 from right to left, the drive lever 271 extends before the shift fork drive device 27 reaches the shift fork 23 to be impacted (as shown). Figure 9 Then, the lever 271 strikes the lower end of the fork 23, causing the fork 23 to rotate. The return spring 24 is stretched, and the fork 23 drives the contour block 21 to rotate, opening the dynamic gate and sending the blood collection tube 9 out of the tube compartment 13. After the lever 271 disengages from the fork 23, the return spring returns the fork 23 to its vertical position. At the same time, the fork drive device 27 controls the lever 271 to retract, avoiding collision with the forks of other tube compartments.

[0088] like Figures 10 to 13 The pipe feeding mechanism shown is located below the material handling mechanism 2 and includes a main slider 31, a gate 32, a secondary guide rail 37, a slider spring 36, a limiting member 35, and a conveying device.

[0089] The main slider 31 is provided with a locking hole 311, which is set along the depth direction of the tube compartment. The size of the locking hole 311 is larger than the size of the various types of blood collection tubes 9, allowing the various types of blood collection tubes 9 to pass through the locking hole 311. A gate 32 is located below the main slider 31, and the gate 32 is provided with a gate hole 322. The size of the gate hole 322 is larger than the size of the various types of blood collection tubes 9, allowing the various types of blood collection tubes 9 to pass through the gate hole 322. A conveying device is connected to the main slider 31 and can drive the main slider 31 to move horizontally back and forth below each tube compartment 13, so that the locking hole 311 can move with the main slider 31 to above the gate hole 322. The fork drive device 27 is set on the main slider 31 and realizes the above-mentioned horizontal back and forth movement behind the back plate 11 with the horizontal back and forth movement of the main slider 31.

[0090] The secondary guide rail 37 consists of two parallel sliding rods, positioned on the gate 32 along the direction in which the conveying device drives the main slider 31 to move horizontally. The main slider 31 is mounted on the secondary guide rail 37 and can reciprocate horizontally along it. When the conveying device drives the main slider 31 to reciprocate, it can also cause the gate 32 to reciprocate horizontally together. Specifically, as shown... Figure 10 , Figure 11 As shown, the gate 32 is a U-shaped component composed of a base plate 311, a left plate 324, and a right plate 323. The base plate 311 is horizontally arranged, and the gate hole 322 is located on the base plate. The main slider 31 and the auxiliary guide rail 37 are located between the left plate 324 and the right plate 323, and the end of the auxiliary guide rail is fixedly connected to the corresponding end of the left plate 324 and the right plate 323.

[0091] The slider spring 36 is set horizontally, consistent with the orientation of the secondary guide rail 37. For example... Figure 11 As shown, the left end of the slider spring 36 is connected to the main slider 31, and the right end is fixedly connected to the right plate 323 of the gate; both the front and rear ends of the main slider 31 are equipped with slider springs 36.

[0092] like Figure 11 As shown, the limiting member 35 is located at the left end of the conveying device and is used to abut against the gate. Specifically, the limiting member includes a T-shaped plate 351 and multiple limiting rods. The T-shaped plate 351 is vertically arranged, and the limiting rods are horizontally arranged on the side of the T-shaped plate facing the gate. When the conveying device drives the main slider 31 and the gate 32 to move together toward the limiting member 35 (i.e., from right to left), the left plate 324 of the gate 32 first abuts against the limiting rods of the limiting member 35, causing the gate 32 to stop moving. The conveying device continues to drive the main slider 31 to move along the secondary guide rail 37 until the locking hole 311 moves with the main slider 31 to above the gate hole 322 (e.g., ...). Figure 13 (As shown). Before the gate 31 abuts against the limiting member 35, the slider spring 36 can pull the main slider 31 with elastic tension to prevent the jamming hole 311 from moving above the gate hole 322 in advance.

[0094] The labeling mechanism 4 is located on the left side below the pipe feeding mechanism 3. The labeling mechanism has a labeling station. When the gate abuts the limiting member 35, the labeling station is located below the gate hole 322.

[0097] like Figure 18The printing mechanism shown is connected to the labeling mechanism 4 and is used to print labels and transport them to the labeling station. Specifically, the printing mechanism 5 is located on the right side below the tube feeding mechanism 3 and includes a first printer 51, a first unwind roller 52, a second unwind roller 53, a rewind roller 54, and a second printer 55. The first printer 51 is connected to the labeling mechanism and is used to print labels and transport them to the labeling station to be affixed to the blood collection tubes. The second printer 55 is located below the first printer 51 and is used to synchronously print the same labels as the first printer 51; these identical labels are used for archiving. The first unwind roller 52 and the second unwind roller 53 are located on one side of the printers. The first unwind roller 52 carries the label paper tape from the first printer 51, and the second unwind roller 53 carries the label paper tape from the second printer 55. The rewind roller 54 is located between the first unwind roller 52 and the first printer 51 and is used to recover the release paper tape from the first printer 51 after the labels have been separated at the labeling station.

[0098] like Figure 1 As shown, tray 6 is located below the labeling station; control circuit board 7 is located on the right side below tube feeding mechanism 3, behind printing mechanism 5; wiring port 71 is provided on the right side of control circuit board 7.

[0099] like Figure 3 As shown, the right side of the housing 8 has a plug hole 81 corresponding to the wiring port 71; the top of the housing 8 has a flip plate 82, which is used to open the top of the housing to add blood collection tubes to the tube compartment 13 or adjust the lateral width of the tube compartment 13 to adapt to the newly added tube type; the upper right side of the front of the housing also has a control display screen 83, which is used to input commands and display information. The control display screen 83 is electrically connected to the control circuit board 7; below the control display screen 83 on the front of the housing, there is also a storage compartment 84.

[0100] The automatic pipe preparation machine in this embodiment has external dimensions of 550mm × 200mm × 450mm, a simple and compact overall structure, and occupies an area of ​​<1m². 2 This enables the miniaturization of the equipment and solves the space limitation problem of existing similar equipment.

[0101] The process of the automatic tube preparation machine for collecting blood collection tubes in this embodiment is as follows: Figure 2 For example, the seven warehouses are arranged from left to right as follows: Warehouse 1, Warehouse 2, Warehouse 3, Warehouse 4, Warehouse 5, Warehouse 6, and Warehouse 7.

[0102] In the initial state, the main slider 31 and the gate 32 are located at the left end of the linear guide 34, and the main slider 31 is located at the right end of the gate 32 (i.e., the main slider 31 abuts against the right plate 323). The slider spring 36 is in its natural state, and the locking hole 311 is misaligned with the gate hole 322 (e.g., ...). Figure 11The shift fork drive device 27, which is set on the main slider 31, is located on the left side below the first tube compartment, and the shift lever 271 is in the retracted state.

[0103] By inputting the command (take blood collection tube from the Nth tube compartment, where N is 1, 2, 3, 4, 5, 6, 7) on the control display screen 83, the stepper motor of the tube delivery mechanism drives the synchronous belt to move the main slider 31 and the shift fork drive device 27 from left to right. The main slider 31 drives the gate 32 to move synchronously to the right along the linear guide rail 34 / linear guide rod 38. When the shift fork drive device 27 passes the shift fork corresponding to the (N-1)th tube compartment, the shift fork drive device 27 drives the lever 271 to extend. As the lever 27 continues to move to the right, it strikes the shift fork corresponding to the Nth tube compartment. The shift fork rotates, causing the contour block 21 in the Nth tube compartment to rotate counterclockwise, pushing the blood collection tube 9 in the temporary storage position of the Nth tube compartment out and into the locking hole 311 of the main slider 31. Then the lever 271 immediately retracts, the stepper motor of the tube delivery mechanism reverses, and drives the synchronous belt to move the main slider 31 and the shift fork drive device 27 from left to right. The fork drive device 27 moves to the left, and the main slider 31 drives the gate 32 to move to the left synchronously along the linear guide rail 34 / linear guide rod 38 through the slider spring 36. The blood collection tube 9 continues to move to the left with the main slider 31. The contour block 21 in the Nth tube compartment is reset under the action of its corresponding reset spring 24, and another blood collection tube 9 enters the temporary storage position. When the gate 32 moves to the left plate 324 and abuts against the limit member 35, it stops moving to the left. The main slider 31 continues to move to the left along the auxiliary guide rail 37 under the drive of the synchronous belt 33 until the main slider 31 moves to the left end of the gate 32 and abuts against the left plate 324, so that the card hole 311 coincides with the gate hole 322. The blood collection tube 9 in the card hole 311 falls from the gate hole 322 into the labeling position of the labeling mechanism 4 below. Then the main slider 31 resets to the right end of the gate 32, the slider spring 36 returns to its natural state, and enters the initial state of the next blood collection tube retrieval.

[0104] When the blood collection tube 9 falls into the labeling station of the labeling mechanism 4, the shafts at both ends of the micro-pressure roller 43 are located at the upper end of the micro-pressure roller groove 431, and the shafts at both ends of the gate roller are located at the right end of the gate roller groove 411. Then, the micro-pressure roller drive device drives the micro-pressure roller 43 to move towards the power roller, fixing the blood collection tube 9 in the labeling station. The first printer 51 delivers the printed label to the surface of the blood collection tube 9, and the power roller 42 rotates, causing the blood collection tube 9 to rotate. The label adheres to the surface of the blood collection tube 9 and is pressed tightly during the rotation of the blood collection tube 9, completing the labeling. Then, the micro-pressure roller 43 resets, the gate roller 41 moves to the right, and the blood collection tube 9 falls from between the gate roller 41 and the power roller 42 into the tray 6 below. It should be noted that when the first printer 51 prints the label, the second printer 52 simultaneously prints the same label and outputs it to the tray 6.

[0105] The automatic tube preparation machine in this embodiment is equipped with multiple tube compartments for storing blood collection tubes. Each compartment has a dynamic gate at its bottom. The tube delivery mechanism can move to the dynamic gate of the compartment corresponding to the required type of blood collection tube. The blood collection tubes in the compartment fall through the dynamic gate into the main slider slot of the tube delivery mechanism, and then through the gate hole on the gate into the labeling station of the labeling mechanism. The printing mechanism prints the label and delivers the label to the labeling station, where the labeling machine completes the labeling. The tubes then fall into the tray, realizing the automatic material handling, tube delivery, and labeling of the automatic tube preparation machine, which significantly improves tube preparation efficiency, accuracy, and reliability, and significantly reduces the error rate compared to manual tube preparation.

[0106] The automated tube preparation machine in this embodiment significantly improves efficiency, with a theoretical single-machine processing capacity of 1000-1200 tubes / hour, representing an efficiency improvement of over 300% compared to manual tube preparation. The average response time of the automated tube preparation machine from receiving the instruction to completing the preparation is ≤1.2 seconds, a 70% reduction compared to manual operation. Accuracy and reliability are significantly improved, with the overall error rate reduced to 0.008%. It also offers significant economic benefits, as a single device can replace 3-5 tube preparation operators, while improving space utilization. It not only meets the accuracy requirements of clinical testing but also promotes the advancement of laboratory automation towards unmanned and intelligent operation, providing key technical support for the construction of smart hospitals.

[0107] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
