DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purposes and effects realized by the present application more clear and easy to understand, the present application is further described below in combination with the drawings and specific embodiments: As Figures 1 to 4As shown, the present application provides a full-automatic conveying type plasma bag sample tube hot cutting device, the plasma bag conveying device 71, the sample positioning device 72, the tube conveying device 73, the tube positioning structure 74 and the hot cutting execution device 75, at least three sample positioning devices 72 are installed on the output end of the plasma bag conveying device 71, and the sample positioning device 72 is used for positioning the plasma bag and the sample tube; the tube conveying device 73 is installed below the plasma bag conveying device 71, the tube positioning structure 74 is installed on the tube conveying device 73, and the tube positioning mechanism is used for positioning the cut sample tube; the hot cutting execution device 75 is arranged above the middle part of the plasma bag conveying device 71, and the hot cutting execution device 75 is used for hot cutting the connection part of the sample tube and the plasma bag positioned on the sample positioning device 72.

[0024] In the present application, the plasma bag conveying device 71 is a chain conveying structure.

[0025] Optionally, the plasma bag conveying device 71 comprises a rack and a conveying chain, the conveying chain is installed beside the rack and can move circularly, the sample positioning device 72 is installed on the conveying chain, a support plate is fixed on the rack, and the support plate supports the sample positioning device 72.

[0026] Since the subsequent sample positioning device 72 will support the hot cutting part, the support plate is designed to support the sample positioning device 72, so as to avoid the failure of hot cutting after hot pressing due to the lack of support of the sample positioning device 72.

[0027] The hot cutting execution device 75 comprises a hot pressing seat 751, a hot pressing head 752, a heating mechanism (not shown in the figure), a guide rod 753, a cutting knife 754, a lifting seat 755, a vertical driving mechanism 756 and a gantry 757, the gantry 757 spans the plasma bag conveying device 71, the vertical driving mechanism 756 is fixed on the gantry 757, the output end of the vertical driving mechanism 756 is connected to the lifting seat 755, the cutting knife 754 is fixed on the lifting seat 755, the lifting seat 755 is penetrated by the guide rod 753, the guide rod 753 is fixed to the hot pressing seat 751, the hot pressing seat 751 is connected to the lifting seat 755 through the second spring 758, the cutting knife 754 can penetrate the hot pressing seat 751 and the hot pressing head 752, the hot pressing head 752 is fixed on the hot pressing seat 751, the heating mechanism for heating the hot pressing head 752 is installed in the hot pressing seat 751, and the second spring 758 is used to make the hot pressing head 752 first tightly contact the sample tube. The cutting knife 754 is used to punch the sample tube. Thus, the hot cutting of the sample tube and the plasma bag is realized, then the sample tube is punched and separated, and the production environment is avoided from being polluted due to the overflow of the plasma.

[0028] Optionally, the tube positioning structure 74 comprises at least four partitions, the tube conveying device 73 is a belt conveying structure, the partitions are fixed on the conveying belt of the tube conveying device 73, and the gap between the adjacent two partitions is used for the sample tube to fall in. The sample tube is separated and output, and the disorder is avoided.

[0029] In this application, the sample retention positioning device includes: a first base 1, a second base 2, a moving mechanism 3, a blood bag storage mechanism 4, and a positioning mechanism 5. The first base 1 is installed next to the second base 2, and there is a gap between the first base 1 and the second base 2. The top of the first base 1 is provided with the blood bag storage mechanism 4, which is used to place the blood bag. A sample retention tube is connected to the end of the blood bag near the second base 2. The moving mechanism 3 is provided between the first base 1 and the second base 2. The moving mechanism 3 is used to clamp the end of the sample retention tube away from the blood bag. The moving mechanism 3 is provided with the positioning mechanism 5, which is used to position the distance between the output end of the moving mechanism 3 and the blood bag. During operation, the blood bag is first placed in the blood bag storage mechanism 4 at the top of the first base 1. The sample retention tube connected to the end of the blood bag near the second base 2 passes through the corresponding structure of the blood bag storage mechanism 4 and extends into the space between the first base 1 and the second base 2. Then, the moving mechanism 3 is activated and moves to the appropriate position through the cooperation of its own structure, clamping the end of the sample retention tube away from the blood bag. At the same time, the positioning mechanism 5 accurately positions the distance between the output end of the moving mechanism 3 and the blood bag, thereby completing the positioning work of the plasma bag sample retention. The hot-cutting device for blood bag storage tubes utilizes a fixed groove and a limiting groove design in the blood bag storage mechanism to ensure stable placement of the blood bag and smooth passage of the blood bag tube. The sliding rod, sliding seat, and fixed block in the moving mechanism work together to flexibly clamp the end of the blood bag tube. The components of the positioning mechanism work together to ensure precise positioning of the distance between the output end of the moving mechanism and the blood bag. When the clamping mechanism presses the blood bag tube against the fixed block, it simultaneously squeezes the positioning post, allowing the positioning block to engage with the positioning strip, enhancing the accuracy and stability of the positioning. Furthermore, the gap between the two sliding rods allows the blood bag tube to fall, and the overall design improves the convenience and accuracy of blood bag sampling operations.

[0030] The blood bag storage mechanism 4 includes a fixed base 41 with a fixed groove for placing the blood bag. A limiting groove 42 for a sample collection tube to pass through is provided on the side of the fixed groove near the second base 2. When the blood bag is placed in the fixed base 41 of the blood bag storage mechanism 4, the blood bag is located in the fixed groove, and its sample collection tube passes through the limiting groove 42 and is connected to the positioning mechanism 5.

[0031] The moving mechanism 3 includes a sliding rod 31, a sliding seat 32, and a fixing block 33. Two sliding rods 31 are provided, with their ends connected to a first base 1 and a second base 2, respectively. The two sliding rods 31 are placed horizontally parallel to each other. The sliding seat 32 is slidably connected to the two sliding rods 31. The fixing block 33 is installed on the side of the sliding block closest to the first base 1 and is used to support the sample tube. When the moving mechanism 3 is working, the sliding seat 32 slides along the horizontally parallel sliding rods 31. After adjusting to a suitable position, the fixing block 33 supports and fixes the sample tube, facilitating cutting of the sample tube by an external cutting machine.

[0032] like Figure 2As shown, the positioning mechanism 5 includes: a clamping mechanism 51, a positioning strip 52, a positioning post 53, a positioning block 54, and a first spring 55. The clamping mechanism 51 is installed on the top of the sliding seat 32 and can clamp the sample tube. The positioning strip 52 is located next to a sliding rod 31, and the two ends of the positioning strip 52 are respectively connected to the first base 1 and the second base 2. The positioning strip 52 has a rack and pinion structure. The upper end of the positioning post 53 passes through the sliding seat 32 and extends into the lower part of the clamping mechanism 51. The lower end of the positioning post 53 is connected to the positioning block 54. One end of the first spring 55 is connected to the positioning block 54, and the other end of the first spring 55 is connected to the inner wall of the sliding seat 32. The elastic force of the first spring 55 is used to keep the positioning block 54 away from the positioning strip 52. The positioning block 54 is used to engage with the positioning block 54 when the clamping mechanism 51 presses the sample tube onto the fixed block 33. When positioning the sample tube, the clamping mechanism 51 is installed on the top of the sliding seat 32 to clamp the sample tube first. The upper end of the positioning post 53 passes through the sliding seat 32 and extends into the lower part of the clamping mechanism 51, and the lower end is connected to the positioning block 54. When the clamping mechanism 51 presses the sample tube onto the fixed block 33, the positioning block 54 engages with the positioning strip 52 under the elastic force of the first spring 55 to achieve precise positioning.

[0033] A gap is formed between the two sliding rods 31 to allow the sample tube to fall.

[0034] like Figure 3 As shown, the clamping mechanism 51 includes a clamping base 511 and a clamping cover 512. The clamping cover 512 is hinged to one end of the clamping base 511 via a hinge. A locking block 513 protrudes upward from the end of the clamping base 511 away from the hinge. A locking protrusion 514 protrudes from the side of the locking block 513 near the clamping cover 512. A groove is formed at the end of the clamping cover 512 near the locking block 513. The locking protrusion 514 engages with the inner wall of the groove. The clamping base 511 can be penetrated by the positioning post 53. The clamping cover 512 is used to press down the positioning post 53. When it is necessary to clamp the sample tube, the clamping cover 512 is manually pressed down. The clamping cover 512 rotates around the clamping base 511 via the hinge, so that the locking protrusion 514 engages with the inner wall of the groove. The clamping cover 512 presses down the positioning post 53, thereby clamping the sample tube onto the fixing block 33.

[0035] A support block 6 is provided on the side of the fixed base 41 near the sliding base 32. The support block 6 can support the sample tube near the end of the blood bag. The support block 6 is used to cut the sample tube with the external cutting mechanism. When cutting is required, the support block 6 supports the sample tube near the end of the blood bag, and the external cutting mechanism cooperates with the support block 6 to cut the sample tube stably.
