[0037] In this embodiment, Figure 1 , Figure 4 and Figures 10 to 14As shown, the sterilization component 2 includes a lower clutch plate 201 rotatably connected to the bottom of the transmission component 4, the bottom surface of the lower clutch plate 201 is fixedly connected to a threaded rod 202, the bottom end of the threaded rod 202 is rotatably connected to a bearing seat 203, and the middle part of the threaded rod 202 is threadedly connected to a lifting block 204, and the lifting block 204 is fixedly connected to a telescopic rod 205 on one side close to the middle of the sterilization chamber 101, and the end of the telescopic rod 205 away from the lifting block 204 is fixedly connected to a vertical guide rail 206, and the vertical guide rail 206 is integrally formed in the middle part of the outer side of the sterilization inner tube 207, and the inner bottom surface of the sterilization inner tube 207 is fixedly connected to a liquid storage chamber 208, and the inner bottom surface of the liquid storage chamber 208 is fixedly connected to the inner bottom surface of the liquid storage chamber 208. A return spring 209 is connected, a piston 2010 is fixedly connected to the top of the return spring 209, a trigger rod 2011 is integrally formed on the top surface of the piston 2010, a plurality of liquid spraying ports 2012 are provided at the tube wall between the sterilization inner tube 207 and the liquid storage chamber 208, an inner connecting rod 2013 is rotatably connected to the middle of the trigger rod 2011, the inner connecting rod 2013 is slidably connected to the inside of an outer connecting sleeve 2014, a scraper 2015 is hinged at one end of the outer connecting sleeve 2014 away from the inner connecting rod 2013, both sides of the outer connecting sleeve 2014 are rotatably connected to the inside of a strip mounting port 216 through a connecting shaft, and a liquid pipette 2017 is connected to one side of the liquid storage chamber 208;An extrusion nozzle is installed inside the liquid spray port 2012, which is not shown in the figure. The inner connecting rod 2013 extends to one end of the inner part of the outer connecting sleeve 2014, and a limited position block is integrally formed. When the device is used, the cutting component 3 first performs a circular cut on the bottom end of the reagent tube. After cutting, the blood in the reagent tube falls into the disinfectant liquid chamber 102 under the action of gravity, and then drives the lower clutch plate 201 to rotate while revolving around the worm gear 301 under the cooperation of the cutting component 3 and the transmission component 4. The rotation of the lower clutch plate 201 drives the threaded rod 202 to rotate, and the threaded rod 202 drives the lifting block 204 to move linearly along the axis direction of the threaded rod 202. The lifting block 204 The up and down movement will drive the sterilization inner tube 207 to rise and fall synchronously. When the sterilization inner tube 207 rises to the inside of the reagent tube, the top of the trigger rod 2011 contacts the top of the inner part of the reagent tube. As the sterilization inner tube 207 continues to rise, the trigger rod 2011 moves downward. The downward movement of the trigger rod 2011 will compress the return spring 209 and push the piston 2010 to move downward along the inside of the liquid storage chamber 208, so that the disinfectant in the liquid storage chamber 208 is sprayed to the inner wall of the reagent tube through the spray port 2012, and the residual blood in the reagent tube is sterilized and disinfected. When the trigger rod 2011 moves downward, it will also move downward through the inner connecting rod 2013. During the downward movement of the inner connecting rod 2013, the inner connecting rod 2013 will slide into the outer connecting sleeve 2014. At this time, the inner connecting rod 2013 can drive the outer connecting sleeve 2014 to rotate. The two sides of the outer connecting sleeve 2014 are rotatably connected to the inner wall of the strip mounting opening 2016 through the connecting shaft. Therefore, when the inner connecting rod 2013 moves, it will drive the outer connecting sleeve 2014 to rotate around the connecting shaft. At this time, the end of the outer connecting sleeve 2014 located on the outside of the sterilization inner tube 207 will drive the scraper 2015 to unfold, so that the scraper 2015 is in contact with the inner wall of the reagent tube. With the cooperation of the cutting component 3 and the transmission component 4, the sterilization Component 2 will rotate, thereby driving scraper 2015 to rotate and scrape off the viscous substances and other impurities remaining on the inner wall of the reagent tube. After the sterilization is completed, the driving motor 3014 in the cutting component 3 reverses to drive the sterilization component 2 to reset. When the sterilization inner tube 207 moves down, the trigger rod 2011 gradually separates from the inner top of the reagent tube, and the reset spring 209 rebounds to reset the trigger rod 2011. During the upward reset process of the trigger rod 2011, the piston 2010 is driven to move upward inside the liquid storage chamber 208. Under the action of negative pressure, the disinfectant in the disinfectant liquid chamber 102 is sucked into the liquid storage chamber 208 through the liquid pipette 2017 to complete automatic liquid replenishment. ;

[0038] In this embodiment, Fig.11As shown, the bottom end of the pipette 2017 extends to the bottom of the disinfectant chamber 102, and a filter head is provided at the bottom end of the pipette 2017; a one-way valve is provided on the inner wall of one end of the pipette 2017 that is connected to the liquid storage chamber 208, which is not shown in the figure. The one-way valve only allows the disinfectant to enter the liquid storage chamber 208 through the pipette 2017, and the filter head can filter the disinfectant entering the pipette 2017. At the same time, the weight of the filter head is used to keep the bottom end of the pipette 2017 always immersed in the disinfectant, so that when the piston 2010 rises and resets, the disinfectant in the disinfectant chamber 102 can be automatically sucked into the liquid storage chamber 208 for filling.

[0039] In this embodiment, Figures 3 to 8 As shown, the cutting assembly 3 includes a driving motor 3014 fixedly mounted on the top of the inner side of the sterilization chamber 101 through a fixing plate, a worm 3015 is fixedly connected to the output end of the driving motor 3014, a worm 3015 is meshed with a worm wheel 301 on one side, three groups of arc grooves 302 are equiangularly distributed on the top of the worm wheel 301, and a follower rod 303 is slidably penetrated inside the three groups of arc grooves 302, and the follower rod 303 is divided into an upper vertical section, a lower vertical section and a horizontal section, and the horizontal section of the follower rod 303 is away from the central axis of the worm wheel 301. The first end of the telescopic rod 304 is fixedly connected to one end of the telescopic rod 304, and the end of the telescopic rod 304 away from the follower rod 303 is fixedly connected to a rotating ring 305, the horizontal section of the follower rod 303 is fixedly connected to the end of the worm gear 301, the outer arc sleeve 306 is slidably connected to the inner arc rod 307, the top of the inner arc rod 307 is fixedly connected to a micro motor 308, and the output end of the micro motor 308 is fixedly connected to a cutting blade 309, and the edge of the cutting blade 309 is larger than that of the outer arc sleeve 306 and the inner arc rod 307. The inner circle of the arc rod 307 is closer to the central axis of the worm gear 301; insert the reagent tube into the middle of the cutting assembly 3, and after the electric push rod 8 cooperates with the arc clamp block 9 to fix the reagent tube, start the drive motor 3014 to drive the worm 3015 to rotate, and the worm 3015 drives the worm gear 301 to rotate. When the worm gear 301 rotates, it drives the follower rod 303 to move through the arc groove 302. When the follower rod 303 approaches the central axis of the worm gear 301, the upper vertical section and the lower vertical section of the follower rod 303 respectively drive the outer arc sleeve 3 06 and the upper rack 402 move synchronously, and the horizontal section of the follower rod 303 will also drive the extension of the telescopic rod 304. When the outer arc sleeve 306 approaches the central axis of the worm gear 301, the diameter of the ring formed by the outer arc sleeve 306 and the inner arc rod 307 gradually decreases until the cutting blade 309 in the middle of the inner arc rod 307 contacts the outer wall of the reagent tube, and the cutting blade 309 rotates at a high speed under the action of the micro motor 308 to cut the reagent tube. At this point, the cutting blade 309 has only completed cutting a small section of the outer wall of the reagent tube.

[0040] In this embodiment, Figure 5 and Figure 7As shown, the outer ring of the rotating ring 305 is provided with a plurality of spherical grooves 3010, and the inner part of the spherical grooves 3010 is clamped with a limiting ball 3011, and the limiting ball 3011 is connected to one end of the extrusion spring 3012, and the end of the extrusion spring 3012 away from the limiting ball 3011 is fixedly installed in the hole opened in the inner ring of the special-shaped seat 3013, and the inner ring of the special-shaped seat 3013 is provided with an annular mounting groove, and the annular mounting groove is rotatably connected with the protrusion of the outer ring of the rotating ring 305; when the cutting blade 309 contacts the reagent tube, the worm gear 301 continues to rotate under the continued drive of the worm 3015, because the inner ring of the outer arc sleeve 306 and the inner arc rod 307 has been blocked from contacting the outer wall of the reagent tube, it cannot continue to shrink, that is, the follower rod 303 cannot continue to move toward the worm gear 301 under the action of the arc groove 302. When the central axis approaches, the worm gear 301 will drive the three groups of follower rods 303 to revolve synchronously around the central axis of the worm gear 301, thereby causing the inner arc rod 307 to revolve, driving the cutting blade 309 to perform a circular motion to cut off the reagent tube, and when the follower rod 303 revolves, it drives the rotating ring 305 to rotate through the telescopic rod 2 304. When the rotating ring 305 rotates, the limiting ball 3011 is intermittently squeezed out from the spherical groove 3010 until the next spherical groove 3010 moves to the limiting ball 3011. Under the action of the extrusion spring 3012, the limiting ball 3011 re-enters the spherical groove 3010. This structure can make the rotating ring 305 rotate when the outer arc sleeve 306 and the inner arc rod 307 cannot approach or move away from the central axis of the worm gear 301, thereby driving the transmission component 4 to operate.

[0041] In this embodiment, Figure 1 , Figure 4 , Figure 5 and Figures 9 and 10As shown, the transmission assembly 4 includes a mounting plate 401 fixedly connected to the bottom surface of the rotating ring 305 and an upper rack 402 fixedly connected to the bottom end of the lower vertical section of the follower rod 303. The side of the mounting plate 401 close to the upper rack 402 is rotatably connected to a transmission gear 403 through a connecting shaft, and a lower rack 404 is meshed below the transmission gear 403. A limit ring 405 is fixedly connected to the bottom surface of the mounting plate 401. Both sides of the lower rack 404 and the upper rack 402 are integrally formed with protrusions, and the protruding part is slidably connected to a guide strip integrally formed on one side of the mounting plate 401. The side of the mounting plate 401 away from the worm gear 301 is fixedly connected to a mounting top plate 40 6. The bottom surface of the mounting top plate 406 is rotatably connected to a planetary gear 407, the bottom surface of the planetary gear 407 is fixedly connected to a fixed sleeve 408, the planetary gear 407 is meshed with a fixed gear ring 409, the fixed gear ring 409 is fixedly connected to the inner top of the sterilization chamber 101, the middle part of the bottom surface of the planetary gear 407 is connected to the top of the spring telescopic rod 4010, and the bottom end of the spring telescopic rod 4010 is fixedly connected to an upper clutch plate 4011, the bottom surface of the upper clutch plate 4011 is in contact with the top surface of the lower clutch plate 201, and the bottom surface of the upper clutch plate 4011 and the top surface of the lower clutch plate 201 are provided with matching V-shaped grooves and V-shaped convex strips;When the rotating ring 305 rotates, it will drive the mounting plate 401 to revolve around the central axis of the worm gear 301. When the mounting plate 401 revolves, it drives the planetary gear 407 to revolve through the mounting top plate 406. During the revolution of the planetary gear 407, it meshes with the fixed gear ring 409 to rotate. The planetary gear 407 drives the upper clutch plate 4011 to rotate through the spring telescopic rod 4010 on the bottom surface. Because the upper clutch plate 4011 and the lower clutch plate 201 are tightly attached under the rebound force of the spring telescopic rod 4010, when the upper clutch plate 4011 rotates, it drives the threaded rod 202 to rotate through the lower clutch plate 201, thereby realizing the sterilization component 2 The sterilization assembly 2 is lifted and lowered, thereby inserting the sterilization assembly 2 into the cut reagent tube for sterilization and disinfection. At the same time, the revolution of the planetary gear 407 will drive the sterilization assembly 2 to revolve, realizing the rotational spraying of disinfectant and the scraping of the viscous material on the inner wall of the reagent tube, cleaning the inside of the reagent tube to prevent the breeding of bacteria. When the worm gear 301 just starts to rotate, the follower rod 303 is driven by the arc groove 302 to move away from or close to the central axis of the worm gear 301 in the radial direction. In this process, the lower vertical section of the follower rod 303 will drive the upper rack 402 to move. For example, the upper rack 402 approaches the central axis of the worm gear 301. The transmission gear 403 drives the lower rack 404 to move away from the central axis of the worm gear 301, so that the three groups of sterilization inner tubes 207 are separated to prevent the sterilization inner tubes 207 from obstructing the bottom ends of the cut reagent tubes from falling. After the sterilization is completed, the arc-shaped clamping block 9 releases the clamping of the reagent tubes, and the bottom ends of the reagent tubes and the reagent tubes that have fallen down will slide down along the inclined filter plate 6 to the collection chamber 103 for temporary storage. The end of the lower rack 404 close to the central axis of the worm gear 301 is frame-shaped and slidably sleeved on the outer side of the vertical guide rail 206. This structure enables the lower rack 404 to drive the sterilization inner tubes 207 to revolve while allowing the sterilization inner tubes 207 to revolve. 7 can be lifted up and down without affecting the vertical position of the lower rack 404. In addition, the two sets of clutch plates are designed to prevent the threaded rod 202 from continuing to rotate and causing overload damage after the lifting block 204 rises or falls to the critical point when the threaded rod 202 rotates. When the rotation of the threaded rod 202 is blocked, the upper clutch plate 4011 cannot drive the lower clutch plate 201 to continue rotating. When the V-shaped convex strip on the bottom surface of the upper clutch plate 4011 conflicts with the V-shaped convex strip on the top surface of the lower clutch plate 201, the upper clutch plate 4011 will be lifted up and compress the spring telescopic rod 4010, blocking the power transmission between the transmission component 4 and the sterilization component 2. ;

[0042] In this embodiment, Figure 2 and Figure 3As shown, the stirring assembly 5 includes a main gear ring 501 rotatably connected to the inner wall of the sterilization chamber 101, the outer ring of the main gear ring 501 is meshed with a main gear 502, and two side gears 503 are meshed on both sides of the main gear 502. The middle of the bottom surface of the main gear 502 and the side gear 503 are fixedly connected with a main shaft 504, the main shaft 504 rotates and penetrates the middle of the top plate of the collection chamber 103, and the bottom end of the main shaft 504 is fixedly connected with a stirring rod 505. The top surface of the main gear ring 501 is rotatably connected to the bearing seat 203, and the main gear ring 501 is penetrated by the pipette 2017; when the threaded rod 202 is driven by the transmission assembly 4 to revolve, the three The threaded rod 202 drives the main gear ring 501 to rotate through the bearing seat 203 at the bottom end, and the main gear ring 501 drives the main gear 502 meshing with it to rotate, and the main gear 502 drives the sub-gears 503 on both sides to rotate. The main gear 502 and the sub-gear 503 both drive the stirring rod 505 to stir the reagent tubes in the collecting chamber 103 through the main shaft 504 at the bottom. After the reagent tubes sterilized by the sterilization component 2 fall into the collecting chamber 103 for temporary storage, they are continuously sterilized by the ultraviolet lamp 7 in the collecting chamber 103. The stirring rod 505 can stir the reagent tubes in the collecting chamber 103, thereby reducing the blind angle of irradiation of the ultraviolet lamp 7.

[0043] In this embodiment, Figure 1 As shown, the edge of the inclined filter plate 6 does not contact the inner wall of the disinfectant chamber 102 , and a feed opening is provided between the disinfectant chamber 102 and the collection chamber 103 , and the bottom edge height of the feed opening is lower than the edge height of the inclined filter plate 6 .

[0044] The use method and advantages of the present invention: When the blood treatment device for hematology is used, the working process is as follows:

[0045] First, insert the reagent tube to be sterilized into the middle of the cutting assembly 3. It should be noted that in the initial state, the annular diameter formed by the outer arc sleeve 306 and the inner arc rod 307 in the cutting assembly 3 is in the maximum state, that is, the follower rod 303 and the upper rack 402 at the bottom are away from the central axis of the worm gear 301 at this time, and the lower rack 404 is in the position closest to the central axis of the worm gear 301. The three groups of sterilization inner tubes 207 in the sterilization assembly 2 are closed and located directly below the reagent tube. This structure can automatically cover the bottom of the reagent tube when the reagent tube is inserted to prevent the reagent tube from being difficult to insert to a certain depth. Moreover, since the distance between the top surface of the sterilization inner tube 207 and the cutting assembly 3 is fixed, the length of the bottom end of the reagent tube cut each time can be guaranteed to be fixed, ensuring that only a small section of the bottom end of the reagent tube is cut off, and then the reagent tube is clamped and fixed by the electric push rod 8 and the arc clamp block 9, and the cutting assembly 3 is started to perform circumcision on the bottom end of the reagent tube. After cutting, the blood in the reagent tube flows out, and then the driving motor 3014 in the cutting assembly 3 is reversed to expand the outer arc sleeve 306 and the inner arc rod 307. At this time, the lower rack 404 approaches the central axis direction of the worm gear 301. As the worm gear 301 rotates The three groups of sterilization inner tubes 207 are in contact with each other, and the rotating ring 305 starts to rotate, driving the threaded rod 202 to rotate while revolving around the worm gear 301. The threaded rod 202 rotates and drives the sterilization inner tube 207 to rise to the inside of the reagent tube to disinfect and sterilize the reagent tube. After the sterilization is completed, the driving motor 3014 reverses again. At this time, the sterilization inner tube 207 is blocked by the inner wall of the reagent tube and cannot expand, that is, the follower rod 303 cannot pass through the upper rack 402 to finally drive the three groups of sterilization inner tubes 207 to move away from each other. Therefore, the worm gear 301 can only drive the rotating ring 305 to rotate first, and then the rotating ring 305 rotates. When the rotating ring 305 rotates, the planetary gear 407 meshes with the fixed gear ring 409, and finally drives the threaded rod 202 below to reverse, and pulls the sterilization inner tube 207 out of the reagent tube. Only then can the three groups of sterilization inner tubes 207 be separated. After the sterilization is completed, the arc clamp block 9 releases the clamp on the reagent tube, so that the reagent tube falls onto the inclined filter plate 6 and slides into the collection chamber 103. The ultraviolet lamp 7 in the collection chamber 103 continues to sterilize to prevent bacteria from growing. The stirring component 5 is started when the sterilization component 2 is running, and the reagent tube in the collection chamber 103 is stirred to reduce the sterilization blind spot of the ultraviolet lamp 7.
