[0001] This invention relates to the field of medical testing, and in particular to an automatic tube preparation machine. Background Technology

[0002] Currently, the common blood collection process in hospitals mainly involves medical staff manually labeling each blood collection tube needed for a patient's test. During the blood collection process, medical staff need to verify the information of the person being collected, print the relevant label based on the information, and then affix the label to the collection tube before they can perform their blood collection work. After the blood collection is completed, the information of the person being collected needs to be verified again to avoid errors. This manual operation is not only inefficient and labor-intensive, but also prone to operational errors that can lead to abnormalities in subsequent sample testing. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the background art and provide an automatic tube preparation machine.

[0025] Example

[0026] like Figures 1-10As shown, the automatic tube preparation machine provided in this embodiment includes a frame 1 and a test tube compartment module 2, a tube feeding device 3, a labeling device 4, a conveying device 5, and a control module 6 installed in the frame 1. The test tube compartment module 2 is installed on the upper part of the frame 1. The test tube compartment module 2 includes a compartment body 21, a discharging device 22, and a guiding device 23. There are multiple compartment bodies 21, which are used to load different types and sizes of blood collection tubes 7. In order to accommodate the various sizes of blood collection tubes 7, an adjusting plate 211 is vertically installed inside the compartment body 21. Each compartment body 21 is equipped with a discharging device 22 and a guiding device 23 at its bottom for quantitatively taking blood collection tubes 7. The tube feeding device 3 is installed in the middle of the frame 1 below the test tube compartment module 2. The tube feeding device 3 is used to feed the tubes into the compartment. The blood collection tubes 7 taken out by the feeding device 22 and the guiding device 23 are conveyed to the labeling device 4 for labeling. The labeling device 4 is installed below one end of the tube feeding device 3. The labeling device 4 prints out the test information and barcode content and affixes it to the corresponding blood collection tube 7. The control module 6 is used to access the hospital's management system to obtain the patient's test information, specifically by accessing the hospital's LIS / HIS system to obtain the patient's current test information. Based on the test information, the control module 2 takes out the corresponding blood collection tube 7 and simultaneously controls the tube feeding device 3 to send the blood collection tubes 7 to the labeling device 4 in sequence. Then, the control module 4 affixes the corresponding label to the corresponding blood collection tube 7. After the labels are affixed, the control module 5 transmits them out together.

[0027] In order to accurately pick up the tube, such as Figures 3-5As shown, the discharging device 22 includes a discharging cylinder 221, a sensing positioning pin 222, and a stepper motor 223. Three grooves 224 adapted to the contour of the blood collection tube 7 are machined on the annular surface of the discharging cylinder 221. A sensing positioning pin 222 is installed at one end of the discharging cylinder 221 to detect the position of the grooves 224. The sensing positioning pin 222 provides reference data for the rotation of the stepper motor 223. Specifically, a photoelectric limit switch is installed on the hopper 21 on one side of the discharging cylinder 221. The photoelectric limit switch confirms the position of the grooves 224 on the discharging cylinder 221 by detecting the position of the sensing positioning pin 222. The photoelectric limit switch can be set at the top or bottom of the discharging cylinder 221 where the grooves 224 are located for precise material handling. The discharging cylinder 221 at both ends of the grooves 224 has clearance grooves 225 adapted to the contour of the blood collection tube 7 cap to prevent the blood collection tube 7 from entering the grooves. The groove 224 is damaged when it enters the groove 224. The two ends of the groove 224 are machined with rounded corners 226. The chamber 21 is equipped with a stepper motor 223 that drives the discharge cylinder 221 to rotate. The guide device 23 includes a fixed block 231, a guide post 232, a spring 233, a guide block 234 and a detection sensor 235. The fixed block 231 is installed at the bottom of the discharge cylinder 221. The guide block 234 is installed on the side wall of the fixed block 231 near the discharge cylinder 221 through the guide post 232. The guide post 232 is equipped with a spring 233 that pushes the guide block 234 to approach the discharge cylinder 221. The side wall of the guide block 234 near the discharge cylinder 221 is machined with a rounded concave surface 236 that matches the contour of the discharge cylinder 221. The fixed block 231 is equipped with a detection sensor 235 that detects whether there is a blood collection tube 7 in the groove 224.

[0028] In order to centralize labeling, such as Figure 2 , Figure 6 As shown, the tube feeding device 3 includes a fixed plate 31, a guide plate 32, a transmission assembly 33, a pusher plate 34, and a pusher motor 35. The fixed plate 31 is horizontally installed below the test tube chamber module 2, and two guide plates 32 are symmetrically installed above the fixed plate 31, forming a V-shaped material trough. A through groove larger than the outer diameter of the blood collection tube 7 body and smaller than the outer diameter of the blood collection tube 7 cap is machined on the fixed plate between the two guide plates 32. The blood collection tube 7 falls onto the guide plate 32 and rolls along the V-shaped guide plate 32 into the through groove, changing the blood collection tube 7 from a horizontal state to a vertical state. The blood collection tube 7 taken out from the test tube compartment module 2 falls between two guide plates 32. The transmission component 33 is located below the guide plate 32. A vertically arranged pusher plate 34 is installed on the transmission component 33. A pusher motor 35 is installed on the fixed plate 31 to drive the pusher plate 34 to move back and forth in the through groove. A drop hole 36 for the blood collection tube 7 to fall into is processed at one end of the through groove. The drop hole 36 is located above the labeling device 4. The pusher motor 35 drives the pusher plate 34 through the transmission component 33 to push the blood collection tube 7 towards the drop hole 36, so that the blood collection tube 7 enters the labeling device 4.

[0029] To ensure the accuracy of labeling, such as Figures 7-9As shown, the labeling device 4 includes a support plate 41 and a pusher device 42, an active roller group 43, a printer module 44, and a barcode inspection module 47 mounted on the support plate 41. The pusher device 42 includes a linear motion module 421, a lower fixed seat 422, an upper fixed seat 423, a driven roller 424, and a photoelectric sensor 425. The linear motion module 421 is a mechanism capable of linear motion, such as a linear push rod or a cylinder. The lower fixed seat 422 is mounted on the movable end of the linear motion module 421, and the upper fixed seat 423 is mounted on the lower fixed seat 422. The driven roller 424 is vertically and rotatably mounted between the upper fixed seat 423 and the lower fixed seat 422. To improve the stability of the blood collection tube 7 when labeling, the driven roller 424... There are two photoelectric sensors 425 installed on one side of the linear motion module 421 to control the movement stroke of the linear motion module 421. A U-shaped notch 426 is machined on the upper fixed seat 423, aligned with the material discharge hole 36. The size of the U-shaped notch 426 is larger than the outer diameter of the blood collection tube 7 and smaller than the through groove of the test tube cap's outer diameter. This supports the blood collection tube 7, allowing it to rotate stably between the driving roller 433 and the two driven rollers 424 when labeled. A material discharge port 41 is machined on the support plate 41 directly below the material discharge hole 36. A vertical plate 45 is installed on one side of the lower fixed seat 422, and a groove aligned with the U-shaped notch 426 is installed on the vertical plate 45 behind the upper fixed seat 423. A fixed stop 46 is provided. The active roller assembly 43 is installed in front of the linear motion module 421. The active roller assembly 43 includes a lower support 431, an upper support 432, an active roller 433, a labeling motor 434, an active pulley 435, a transmission belt 436, a driven pulley 437, and an edge-tracking sensor 438. The upper support 432 is installed on the lower support 431. The active roller 433 is vertically installed between the upper support 432 and the lower support 431. The labeling motor 434 is installed on the lower support 431 on one side of the active roller 433. The output shaft of the labeling motor 434 passes through the lower support 431 and is connected to the active pulley 435. The bottom end of the active roller 433 passes through the lower support 431 and is connected to the driven pulley 437. A drive belt 436 connects the drive pulley 435 and the driven pulley 437. An edge-tracking sensor 438 is mounted on the upper support 432 on one side of the drive roller 433. The label-tracking sensor 438 can be a photoelectric sensor 425 or a laser sensor; for improved accuracy, a laser sensor is preferred. An arc groove 439, avoiding the blood collection tube 7, is mounted on the upper fixed seat 423. The printer module 44 is mounted on one side of the drive roller 433, with its label outlet 12 aligned with the drive roller 433. The barcode verification module 47 is mounted on the vertical plate 45 and is used to verify the label on the blood collection tube 7. The barcode verification module detects the label between the two driven rollers 424. When the barcode verification module 47 detects the label on the blood collection tube 7...This indicates that labeling is complete and can be correctly identified. At this point, the linear motion module 421 retracts, continues to retract after passing the discharge port 411, and, under the action of the fixed stop block 46, keeps the blood collection tube 7 above the discharge port 411. After the blood collection tube 7 moves out from the U-shaped notch, it falls along the discharge port 411 onto the delivery device 5.

[0030] like Figure 10 As shown, a conveying device 5 is installed on the frame 1 below the material discharge port 411. The conveying device 5 includes a bracket 51, a conveyor belt 52, a transmission motor 55, a baffle 53, and a guide plate 54. The bracket 51 is installed inside the frame 1, and the conveyor belt 52 is rotatably mounted on the bracket 51. The transmission motor 55, which drives the conveyor belt 52 to rotate forward and backward on the bracket 51, is installed on the bracket 51. The baffle 53 is installed on the bracket 51 on both sides of the material discharge port 411. The baffle 53 can prevent the blood collection tube 7 from popping out of the conveyor belt. The conveyor belt 52 has a guide plate 54 that is obliquely mounted on the frame 1 at the end of the conveyor belt 52. The frame 1 has a housing 11 installed on its outer side. The lower end of the guide plate 54 faces the housing 11. The housing 11 has an outlet 12 that is aligned with the guide plate 54. After all the blood collection tubes 7 are prepared, the transmission motor 55 moves all the blood collection tubes 7 out at once through the conveyor belt 52. The housing has two outlets 12. By using the forward and reverse rotation of the transmission motor 55, the tubes can be fed to two different workstations, thereby improving the blood collection efficiency.

[0031] The method of using this invention is as follows:

[0032] First, the position of the adjusting plate 211 within the chamber 21 is adjusted according to the size of the blood collection tube 7. Then, the blood collection tube 7 is inserted into the corresponding chamber 21. Subsequently, the control module 6 obtains the patient's current test information and sends the required quantity and type of blood collection tube 7 to the test tube chamber module 2 based on the test information. When the test tube chamber module 2 receives the test tube request, it controls the corresponding stepper motor 223 to rotate. The stepper motor 223 drives the dispensing cylinder 221 to rotate, causing the groove 224 to face the storage space of the test tube chamber. The blood collection tube 7 falls into the groove 224, and the clearance grooves 225 at both ends of the groove 224 can accommodate the size of the cap of the blood collection tube 7. Then, the stepper motor 22... 3. Continue rotating the groove 224 to the guide device 23. At this time, the detection sensor 235 of the guide device 23 detects the blood collection tube 7 and counts it to achieve quantitative discharge. As the stepper motor 223 continues to rotate, the groove 224 containing the blood collection tube 7 rotates to the bottom of the discharge cylinder 221, pouring out the blood collection tube 7 and completing a single tube retrieval operation. The blood collection tube 7 falls onto the guide plate 32. At this time, the pusher plate 34, under the action of the pusher motor 35, pushes the retrieved blood collection tube 7 towards the discharge hole 36 and enters the labeling device 4 through the discharge hole 36. The test tube chamber module 2 only retrieves one blood collection tube 7 at a time, which can avoid the blood collection tubes 7 squeezing each other. After the blood collection tube 7 enters the labeling device 4, it falls onto the U-shaped notch 426 of the upper fixed seat 423. Then, the linear motion module 421 extends and lifts the blood collection tube 7 towards the active roller group 43, positioning the blood collection tube 7 between the active roller 433 and the driven roller 424. Simultaneously, the photoelectric sensor 425 detects the moving distance. After it moves into position, the labeling motor 434 drives the active roller 433 to rotate. Under the action of friction, the active roller 433 and the driven roller 424 drive the blood collection tube 7 to rotate. The printer module 44 removes the printed label, and the edge-tracking sensor 438 confirms the reference position of the label on the test tube. When all the labels have been removed, the front of the label... The end contacts the side wall of the blood collection tube 7 and is pasted onto the blood collection tube 7 as the blood collection tube 7 rotates. The barcode inspection module 47 detects whether the label is properly affixed between the two driven rollers 424. After the label is properly affixed, the linear motion module retracts, passes the discharge port 411 and continues to move backward. Under the action of the fixed stop 46, the blood collection tube 7 is blocked above the discharge port 411. As the linear motion module 421 continues to move backward, the blood collection tube 7 is detached from the upper fixed seat 423 and falls onto the conveyor belt 52. The above steps are repeated until the required blood collection tube 7 is ready. Then, the conveyor belt 52 transmits all the blood collection tubes 7 to the guide plate 54 and finally removes them from the tube preparation machine from the outlet 12.
