Description

Technical Field

[0001] This invention relates to the medical field, specifically to a blood sample processing device for infectious diseases. Background Technology

[0002] When testing blood in the infectious disease department of a hospital, the blood used needs to be processed to avoid contamination by medical waste. The handling of blood after testing in the infectious disease department requires extra caution. The current blood processing method generally uses high temperature and high pressure to inactivate the blood, and then incinerates it. However, the waste blood is sealed inside the vacuum blood collection tube. Therefore, directly incinerating the blood inside the vacuum blood collection tube after inactivation will pollute the environment during the combustion process, and the blood inside the vacuum blood collection tube is difficult to burn directly.

The stop rod abuts against the top rod.

[0011] The feeding mechanism includes a feeding plate movably disposed inside the machine housing. The feeding plate is provided with two extrusion rods and two first elastic elements disposed in the inner wall of the machine housing. The feeding plate has a feeding port. A first motor is disposed on the inner wall of the machine housing. The first motor is connected to an output rod via gears.

[0012] The housing is equipped with a heating wire and multiple pressurization ports. The heating wire heats the interior of the housing, and the pressurization ports pressurize the interior of the housing.

[0013] Beneficial effects:

[0014] The feeding mechanism separates the internal and external spaces of the machine casing during feeding, preventing blood from spilling out when the vacuum blood collection tubes are cut by the cutting mechanism. The feeding mechanism also pushes the vacuum blood collection tubes from the outside of the casing to the inside for sterilization. The cutting mechanism cuts the vacuum blood collection tubes, allowing blood to flow out and into the casing. The drive mechanism seals the feeding mechanism after the vacuum blood collection tubes are pushed into the casing, ensuring a sealed interior. The separation mechanism separates the cut vacuum blood collection tubes, facilitating blood flow. The unloading mechanism agitates the cut vacuum blood collection tubes, making it easier for blood to drain after separation. The blood and cut vacuum blood collection tubes are then collected separately for later incineration, preventing environmental pollution during incineration. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] In one embodiment, please refer to the appendix to the specification. Figure 1-8 As shown, the present invention discloses a blood sample processing device for infectious diseases, comprising a housing 1, wherein a feeding mechanism 2 is provided on the housing 1, the feeding mechanism 2 being used to push vacuum blood collection tubes into the interior of the housing 1; a driving mechanism 3 is provided inside the housing 1 above the feeding mechanism 2, the driving mechanism 3 being used to block the feeding mechanism 2; a cutting mechanism 5 is provided inside the housing 1 in cooperation with the feeding mechanism 2, the cutting mechanism 5 being used to cut the vacuum blood collection tubes clamped on the feeding mechanism 2; a separation mechanism 6 is provided below the cutting mechanism 5, the separation mechanism 6 moving upward to separate the cut vacuum blood collection tubes; and a discharging mechanism 4 is provided below the separation mechanism 6, the discharging mechanism 4 being used to collect the separated vacuum blood collection tubes.

[0027] The feeding mechanism 2 separates the internal and external spaces of the housing 1 during feeding, preventing blood from overflowing from the housing 1 when the vacuum blood collection tube is cut by the cutting mechanism 5. The feeding mechanism 2 also pushes the vacuum blood collection tube from the outside of the housing 1 into the inside for sterilization. The cutting mechanism 5 cuts the vacuum blood collection tube, allowing blood to flow out and into the housing 1. The driving mechanism 3 seals the feeding mechanism 2 after pushing the vacuum blood collection tube into the housing 1, ensuring the housing 1 remains sealed. The separation mechanism 6 separates the cut vacuum blood collection tube, facilitating blood flow. The unloading mechanism 4 shakes the cut vacuum blood collection tube, making it easier for blood to drain after separation, and separating the blood and the cut tube for later incineration, preventing environmental pollution during incineration.

[0028] The feeding mechanism 2 includes a feeding port 21 on the housing 1, a feeding groove 23 on one side of the feeding port 21, and guide plates 22 on both sides of the feeding groove 23. The guide plates 22 are used to guide the vacuum blood collection tube into the interior of the feeding groove 23. A sealing component 24 is provided inside the feeding groove 23 to seal the feeding groove 23. An inlet 27 communicating with the feeding groove 23 is provided inside the housing 1. A rotating rod 25 is provided inside the feeding groove 23 to push the vacuum blood collection tube through the inlet 27 into the interior of the housing 1.

[0029] A toothed plate 211 is connected to the drive mechanism 3. A transmission wheel 210 meshing with the toothed plate 211 is provided on one side of the toothed plate 211. A transmission rod 26 is provided on the transmission wheel 210. A rotating rod 25 is on the transmission rod 26. A rod groove 29 is provided inside the housing 1. The rotating rod 25 rotates inside the rod groove 29. When the drive mechanism 3 moves down, it drives the transmission rod 26 to rotate. A transverse support rod 28 is provided inside the housing 1. The support rod 28 is flush with the inlet 27.

[0030] The sealing assembly 24 includes a partition plate 241 rotatably mounted on the inner wall of the feed trough 23. A fixing pin 244 is provided on the housing 1. The partition plate 241 is rotatably connected to the fixing pin 244. A guide pin 242 is provided on the partition plate 241. A guide groove 243 is provided on the driving component 31. The guide pin 242 slides inside the guide groove 243. When the driving mechanism 3 moves down, the guide groove 243 presses the guide pin 242, causing the partition plate 241 to rotate around the fixing pin 244.

[0031] The feed inlet 21 facilitates the insertion of vacuum blood collection tubes containing waste blood. Upon entering the feed trough 23, the blood collection tubes are guided by the guide plate 22, allowing them to enter laterally. When fed via an external conveyor belt, the blood collection tubes easily enter the feed trough 23. The partition plate 241 within the feed trough 23 is blocked when the blood collection tubes are inside. After a specified number of blood collection tubes are inserted through the feed inlet 21, the drive mechanism 3 moves downwards, pushing the toothed plate 211 to rotate downwards. The toothed plate 211 drives the transmission wheel 210 to rotate, which in turn drives the transmission rod 26 to rotate. The rotation of the transmission rod 26 then drives multiple rotating rods 25 connected to it to rotate synchronously. When the rotating rod 25 rotates, it pushes the blood collection tube located between the two rotating rods 25 from the inlet 27 into the support rod 28. As the blood collection tube continuously enters through the inlet 27, it is squeezed onto the support rod 28. The support rod 28 is preferably L-shaped to facilitate the rotating rod 25 to clamp multiple blood collection tubes. Under the push of the driving mechanism 3, the guide groove 243 provided on the driving mechanism 3 moves downward and squeezes onto the guide pin 242, forcing the guide pin 242 to rotate around the fixed pin 244. The guide pin 242 is connected to the partition plate 241, and the partition plate 241 rotates synchronously around the fixed pin 244 until the partition plate 241 opens the feed chute 23. When the driving member 31 continues to move downward, the toothed plate 211 rotates to push the rotating rod 25 to move the blood collection tube.

[0032] The drive mechanism 3 includes a drive component 31 disposed inside the housing 1. A sealing plate 32 is disposed at the bottom of the drive component 31. The sealing plate 32 is used to block the feed inlet 21. A guide block 33 is disposed on the side wall of the sealing plate 32. A moving rod 34 is connected to the bottom of the guide block 33. A guide groove 243 is provided on the moving rod 34.

[0033] When the partition plate 241 is opened, the sealing plate 32 blocks the feed inlet 21. When the sealing plate 32 is open for feeding, the partition plate 241 is sealed, so that the inside of the housing 1 is always sealed, which makes it easy for the blood inside the blood collection tube after cutting to not spill out; the inside and outside of the housing 1 are separated; the guide groove 243 moves with the movement rod 34 through the set guide groove 243, which is set with an arc section and a vertical section. When the movement rod 34 moves down, the guide pin 242 first moves inside the arc section and pushes the partition plate 241 to rotate. When the guide pin 242 enters the inside of the vertical section, the partition plate 241 does not rotate and always blocks the feed inlet 21.

[0034] The cutting mechanism 5 includes a rotating plate 51 rotatably disposed inside the housing 1. A second motor 52 is disposed inside the rotating plate 51. A worm gear 53 is connected to the output shaft of the second motor 52. A worm wheel 56 is disposed below the worm gear 53. A cutting blade 54 is connected to the worm wheel 56. The cutting blade 54 is rotatably disposed on the rotating plate 51. A rotating rod 55 is disposed on the rotating plate 51. A second helical gear 57 is disposed at the end of the rotating rod 55. The second helical gear 57 is connected to the feeding mechanism 4.

[0035] The separation mechanism 6 includes a top rod 61 disposed at the bottom of the rotating plate 51. A stabilizing plate 67 is disposed inside the housing 1. A sleeve rod 66 is disposed on the stabilizing plate 67. A second elastic element 65 is disposed inside the sleeve rod 66. An inner rod 64 is disposed inside the sleeve rod 66. The second elastic element 65 is used to push the inner rod 64 to reset. A separation rod 63 is fixed to the top of the inner rod 64. A stop rod 62 is connected to the end of the separation rod 63. The stop rod 62 abuts against the top rod 61.

[0036] After the blood collection tubes enter the support rod 28 and are clamped, multiple blood collection tubes are simultaneously cut by the cutting blade 54. When the rotating plate 51 rotates from the inclined position to the horizontal position, the cutting blade 54 will cut the blood collection tubes open. At this time, the waste blood inside the blood collection tubes will enter the feeding mechanism 4. In order to speed up the discharge of blood from the broken blood collection tubes and reduce the discharge time, the top rod 61 pushes the cut blood collection tubes upwards, causing the blood collection tubes to rotate around the support rod 28 and fall onto the feeding mechanism 4. When the rotating plate 51 rotates... When the rotating plate 51 moves downward, the top rod 61 connected to its bottom moves downward. When the top rod 61 moves downward, it presses against the abutment rod 62. The abutment rod 62 is connected to the separating rod 63. At this time, the separating rod 63 moves downward synchronously with the abutment rod 62, so that the inner rod 64 connected to the separating rod 63 is compressed into the inside of the sleeve rod 66, and the second elastic element 65 is compressed. After the cutting is completed, the rotating plate 51 is reset, so that the separating rod 63 moves upward. The separating rod 63 pushes the cut blood collection tube upward, and the blood collection tube rotates around the support rod 28.

[0037] The feeding mechanism 4 includes a feeding plate 41 movably disposed inside the housing 1. The feeding plate 41 is provided with two extrusion rods 40 and two first elastic elements 49 disposed in the inner wall of the housing 1. The feeding plate 41 has a feeding port 43. A first motor 47 is disposed on the inner wall of the housing 1. The first motor 47 is connected to an output rod 46 via gears. A top block 45 is disposed on the output rod 46. The top block 45 cooperates with the extrusion rods 40. A first helical gear 48 is disposed above the output rod 46 and cooperates with a second helical gear 57.

[0038] When the blood collection tubes fall from the support rod 28 onto the feeding plate 41, the feeding plate 41 is tilted and has gaps between its sides and the inner wall of the housing 1, allowing blood to flow downwards through these gaps. The first motor 47, when adjusting the rotating plate 51, simultaneously drives the top block 45 to rotate. The rotation of the top block 45 drives the extrusion rod 40 to move up and down. As the extrusion rod 40 moves up and down, it causes the feeding plate 41 to vibrate, causing the blood collection tubes on the feeding plate 41 to discharge their blood during this vibration. The feeding plate 41 has multiple discharge slots 44 to facilitate the downward discharge of blood from both sides of the feeding plate 41. The discharged blood collection tubes then enter the receiving box 42. Once a certain amount of blood collection tubes are stored in the receiving box 42, they are removed and processed uniformly.

[0039] The housing 1 is provided with a heating wire 12 and a plurality of pressure ports 11. The heating wire 12 heats the interior of the housing 1, and the pressure ports 11 are used to pressurize the interior of the housing 1.

[0040] By providing a heating wire 12 and multiple pressurization ports 11 inside the casing 1, it is convenient to first perform high-temperature and high-pressure sterilization and inactivation treatment on the blood collection tubes and blood, and then incinerate them after the treatment is completed.

[0041] In use, the discarded blood collection tubes are first placed on a conveyor belt, which then feeds them into the inlet 21. The blood collection tubes then enter laterally into the feed trough 23 through the inlet 21. As the blood collection tubes enter the feed trough 23, the guide groove 243 on the moving rod 34 moves downward under the push of the drive member 31. The guide groove 243 presses against the guide pin 242, forcing the guide pin 242 to rotate around the fixed pin 244. The guide pin 242 is connected to the partition plate 241, which rotates synchronously around the fixed pin 244 until the partition plate 241 opens the feed trough 23. As the drive member 31 continues to move downward, the toothed plate 211 rotates, pushing the rotating rod 25 to move the blood collection tubes. After a specified number of blood collection tubes are fed into the inlet 21, the moving rod 34 pushes the toothed plate 211 to rotate downward, and the toothed plate 211 drives the transmission wheel 21. When the drive wheel 210 rotates, it drives the drive rod 26 to rotate. The rotation of the drive rod 26 drives the multiple rotating rods 25 connected to it to rotate synchronously. When the rotating rods 25 rotate, they push the blood collection tubes located between the two rotating rods 25 from the inlet 27 into the support rod 28. As the blood collection tubes continuously enter the inlet 27, they are squeezed onto the support rod 28. The support rod 28 is preferably L-shaped to facilitate the rotating rods 25 to clamp the multiple blood collection tubes. When the drive component 31 moves upward, it drives the guide groove 243 to move upward. The guide groove 243 squeezes onto the guide pin 242, forcing the guide pin 242 to rotate around the fixed pin 244. The guide pin 242 is connected to the partition plate 241, and the partition plate 241 rotates synchronously around the fixed pin 244 until the partition plate 241 blocks the feed chute 23. At this time, the toothed plate 211 and the rotating rod 25 hold the blood collection tubes in place. To separate the blood collection tubes from the waste blood, after the blood collection tubes enter the support rod 28 and are clamped, multiple blood collection tubes are simultaneously cut by the cutting blade 54. When the rotating plate 51 rotates from the inclined position to the horizontal position, the cutting blade 54 cuts open the blood collection tubes. At this time, the waste blood inside the blood collection tubes enters the feeding mechanism 4. To accelerate the discharge of blood from the broken blood collection tubes and reduce the discharge time, the top rod 61 pushes the cut blood collection tubes upwards, causing the blood collection tubes to rotate around the support rod 28 and fall onto the feeding mechanism 4. When the rotating plate 51 rotates, it drives the top rod 61 connected to its bottom to move downward. When the top rod 61 moves downward, it presses against the abutment rod 62. The abutment rod 62 is connected to the separating rod 63. At this time, the separating rod 63 moves downward synchronously with the abutment rod 62, so that the inner rod 64 connected to the separating rod 63 is compressed into the inside of the sleeve rod 66, and the second elastic element 65 is compressed. After the cutting is completed, the rotating plate 51 is reset, so that the separating rod 63 moves upward. The separating rod 63 pushes the cut blood collection tube upward, and the blood collection tube rotates around the support rod 28.When the blood collection tubes fall from the support rod 28 onto the feeding plate 41, the feeding plate 41 is tilted and has gaps between its sides and the inner wall of the housing 1, allowing blood to flow downwards through these gaps. The first motor 47, when adjusting the rotating plate 51, simultaneously drives the top block 45 to rotate. The rotation of the top block 45 drives the squeezing rod 40 to move up and down, causing the feeding plate 41 to vibrate. This vibration causes the blood collection tubes on the feeding plate 41 to discharge their blood. The feeding plate 41 has multiple feeding slots 44 to facilitate the downward discharge of blood from both sides. After the blood is discharged, the blood collection tubes enter the receiving box 42. The housing 1 has a heating wire 12 and multiple pressurization ports 11 inside, allowing for high-temperature and high-pressure sterilization and inactivation of the blood collection tubes and blood. Once a large number of blood collection tubes are stored in the receiving box 42, they are removed and incinerated.
