[0002] Blood testing equipment used in medical examinations is a vital component of the modern medical system, and plays an irreplaceable role in diagnosing diseases, monitoring health conditions, and guiding treatment plans. These devices cover a range of tools and techniques from basic to highly specialized, and can analyze cell counts, chemical composition, pathogen identification, and other aspects in blood samples. High-quality blood testing equipment greatly improves the speed and accuracy of diagnosis and treatment, reduces the misdiagnosis rate, and lays the foundation for personalized medicine. Blood testing equipment for medical examinations is a bridge between clinical decision-making and patient health, and its importance is self-evident.

[0003] While the drawn blood is waiting to be tested, there is a possibility that the liquid surface of the drawn blood sample will coagulate and form clots. When the testing equipment draws blood samples for testing, the presence of blood clots in the blood may cause the suction equipment to be blocked, affecting the efficiency of blood testing. At the same time, the presence of clots may cause a decrease in the accuracy of blood testing, resulting in inaccurate test data. At the same time, during the process of drawing blood and transporting it, blood may drip from the surface of the suction equipment, causing secondary contamination to the inside of the equipment. Therefore, the present application provides a blood testing equipment for medical examination to meet the needs. Summary of the invention

[0043] like Figures 1 to 12As shown, an embodiment of the present invention provides a blood testing device for medical examination, including a device box 1, a display device 2 is installed on the top of the device box 1, a control module 20 is installed on one side of the top of the device box 1, electric slide rails 3 are installed on both sides of the inner wall of the device box 1, a mounting base 30 is sleeved on the surface of the electric slide rail 3, an electric slide rail 2 31 is installed at one end of the mounting base 30, a mounting bracket 32 ​​is sleeved on the surface of the electric slide rail 2 31, an electric push rod 33 is installed on one side of the inner wall of the mounting bracket 32, a rotating magnetic suction cup 34 is installed at the bottom end of the electric push rod 33, a test tube holder 4 is installed at the bottom end of the inner wall of the device box 1, and the top of the test tube holder 4 is nested and installed There are multiple groups of test tubes 5, which are equidistantly arranged at the top of the test tube holder 4, and an analysis device 6 is installed on one side of the inner wall of the equipment box 1; a suction component 7 is installed on one side of the bottom end of the mounting bracket 32, and the suction component 7 is used to aspirate and transfer the blood in the test tube 5; a rotating component 8 is installed on the other side of the bottom end of the mounting bracket 32, and the rotating component 8 is used to disassemble the cannula 94 through the disassembly component 9; a disassembly component 9 is installed on one side of the rotating component 8, and the disassembly component 9 is used to disassemble the cannula 94; the rotating component 8 is located on one side of the suction component 7, and the disassembly component 9 is located on one side of the rotating component 8.

[0044] By setting up the suction component 7 and utilizing the excellent chemical stability and low surface tension characteristics of polytetrafluoroethylene, blood can be prevented from remaining on the inner wall of the suction tube 71 during blood suction and transport inspection, thereby affecting the detection data during blood testing. The rotating component 8 is used to disassemble the cannula 94 through the disassembly component 9. At the same time, the strong coercive force of neodymium iron boron is utilized to ensure the service life of the permanent magnetic suction cup 88 and reduce the cost of subsequent replacement and maintenance. The blood surface is damaged by the rotatable support plate 99 to avoid agglomeration of the blood surface and blockage during suction. At the same time, the excellent chemical stability of polytetrafluoroethylene and its almost non-reaction with other substances are utilized to increase the service life of the cannula 94 and the support plate 99.

[0045] like Figures 4 to 7As shown, the suction assembly 7 includes a suction pipe 71, which is mounted at the bottom end of the mounting bracket 32, a piston disc 70 is mounted in the internal cavity of the suction pipe 71, a bottom plate 72 is provided through the inner wall of the bottom of the suction pipe 71, the cross-sectional structure of the bottom plate 72 is designed as a circular structure with a circular hole in the middle, a slide groove 720 is provided through the inner wall of the circular hole of the bottom plate 72, and the piston disc 70 slides while driving the output capillary 76 and the multiple groups of suction baffles 77 to slide synchronously, and then the inner wall of the slide groove 720 contacts the surface of the card column 78, a hollow push rod 73 is mounted on the top of the piston disc 70, a magnetic disk 74 is mounted on the top of the part of the hollow push rod 73 extending out of the suction pipe 71, the magnetic disk 74 is magnetically attracted to the rotating magnetic suction cup 34, an elastic telescopic rod 75 is elastically mounted on the inner wall of the hollow push rod 73, and the bottom of the elastic telescopic rod 75 An output capillary 76 is connected to the end, and a suction baffle 77 is installed on the surface of the output capillary 76. The number of suction baffles 77 is set to multiple groups, and the multiple groups of suction baffles 77 are equidistantly arranged on the surface of the output capillary 76. A clamping column 78 is installed on one side of the suction baffle 77 of the group close to the elastic telescopic rod 75 among the multiple groups of suction baffles 77, and a through hole 79 is installed through the surface. The number of through holes 79 is set to two, and the bottom end of the through hole 79 is connected to the output capillary 76 through a hard tube. The materials of the piston disk 70, the hollow push rod 73, the output capillary 76, the suction baffle 77, and the clamping column 78 are all set to polytetrafluoroethylene. A double-groove clamping ring 710 is installed at the bottom end of the suction tube 71. The material of the double-groove clamping ring 710 is set to butadiene rubber, and the surface of the double-groove clamping ring 710 is in contact with the surface of the inserted convex ring 95.

[0046] The operator first starts the electric slide rail 1 3 through the control module 20. Under the action of the electric slide rail 1 3, the mounting base 30 slides in the direction of the electric slide rail 1 3. While the mounting base 30 slides, it drives the electric push rod 1 33 and the rotating magnetic suction cup 34 to slide synchronously. At the same time, the mounting base 30 drives the suction tube 71 to slide synchronously to the top position of the test tube 5. Then the control module 20 starts the electric slide rail 2 31. Under the action of the electric slide rail 2 31, the mounting bracket 32 ​​slides downward in the direction of the electric slide rail 2 31. While the mounting bracket 32 ​​slides, it drives the suction tube 71 and the insertion tube 94 to approach and enter the interior of the test tube 5.

[0047] Subsequently, the control module 20 controls the electric push rod 33 to start, and the electric push rod 33 drives the rotating magnetic suction cup 34 to slide upward. While the rotating magnetic suction cup 34 slides, it drives the magnetic disk 74 to slide upward synchronously through magnetic adsorption. While the magnetic disk 74 slides, it drives the hollow push rod 73 and the piston disk 70 to slide upward synchronously, so that the piston disk 70 forms a suction effect in the internal cavity of the suction tube 71. Under the sliding suction action of the piston disk 70, the blood in the test tube 5 passes through the cannula 94 and enters the suction tube 71. While the piston disk 70 slides, it drives the output capillary 76 and the multiple groups of suction baffles 77 to slide synchronously. After that, the inner wall of the slide groove 720 contacts the surface of the card column 78. Through the array spacing effect between the multiple groups of suction baffles 77, the suction baffle 77 changes the flow state of the blood at intervals when the sucked blood passes through the output capillary 76 and the multiple groups of suction baffles 77, so as to avoid agglomeration during the blood suction process.

[0048] When the blood is drawn, the control module 20 controls the rotating magnetic suction cup 34 to rotate. When the rotating magnetic suction cup 34 rotates, the magnetic disk 74 is driven to rotate synchronously through magnetism. When the magnetic disk 74 rotates, the hollow push rod 73 and the piston disk 70 are driven to rotate synchronously. When the hollow push rod 73 rotates, the output capillary 76 and the multiple groups of suction baffles 77 are driven to rotate synchronously through the elastic telescopic rod 75. The surface of the clamping column 78 of one group of suction baffles 77 among the multiple groups of suction baffles 77 fits the slide groove 720 and rotates. When the clamping column 78 rotates, it enters the horizontal channel in the middle of the slide groove 720, realizing the clamping effect between the clamping column 78 and the slide groove 720. Under the clamping action of the clamping column 78 and the slide groove 720, this group of suction baffles 77 and the bottom plate 72 are kept in a clamping state.

[0049] Subsequently, the control module 20 controls the electric slide rail 3 to start, and under the action of the electric slide rail 3, the mounting base 30 slides along the direction of the electric slide rail 3. While the mounting base 30 slides, it drives the electric push rod 33 and the rotating magnetic suction cup 34 to slide synchronously. At the same time, the mounting base 30 drives the suction tube 71 to slide synchronously to reach the top of the analysis equipment 6 at the top position of the inspection test tube 5.

[0050] The control module 20 controls the electric push rod 33 to start, and the electric push rod 33 drives the rotating magnetic suction cup 34 to slide downward. While the rotating magnetic suction cup 34 slides downward, it drives the magnetic disk 74 to slide downward synchronously through magnetic adsorption. While the magnetic disk 74 slides, it drives the hollow push rod 73 and the piston disk 70 to slide downward synchronously. At this time, one set of suction baffles 77 and the bottom plate 72 are kept in a clamping state. When the hollow push rod 73 slides downward, the inner wall of the hollow push rod 73 pushes the elastic telescopic rod 75 to contract. At the same time, the inner wall of the piston disk 70 is in the hollow push rod 73. The piston disc 70 slides against the surface of the output capillary 76 under the pushing action. The piston disc 70 squeezes the blood drawn from the suction tube 71 while sliding, causing the blood to enter the through holes 79 on the surface of one group of suction baffles 77. At the same time, under the continuous squeezing action of the piston disc 70, the blood enters the output capillary 76 through the hard tube at the bottom of the through hole 79. After entering the output capillary 76, the blood falls from the bottom of the output capillary 76 into the analysis device 6 under the action of gravity. The operator can record and analyze the blood information detected by the analysis device 6 through the display device 2.

[0051] By utilizing the excellent chemical stability and low surface tension of polytetrafluoroethylene, blood can be prevented from remaining on the inner wall of the suction tube 71 when blood is extracted and transported for testing, thereby affecting the test data during blood testing. At the same time, the rotation effect of the support plate 99 can be used to avoid blood clots on the blood surface, further ensuring the detection effect of blood.

[0052] like Figure 8 and Fig. 9 As shown, the rotating assembly 8 includes a rotating base 81, which is mounted on one side of the inner wall of the mounting bracket 32, a geared disc 82 is mounted on the top of the rotating base 81, a bevel gear 83 is meshed on one side of the top of the geared disc 82, the bevel gear 83 is mounted on the inner wall of the mounting bracket 32, a turntable 84 is mounted on one end of the bevel gear 83 extending out of the mounting bracket 32, an electric push rod 85 is mounted on the top of the inner wall of the rotating base 81, a sliding base 86 is connected to the bottom end of the electric push rod 85, a positioning hole 87 is mounted on one side of the sliding base 86, the number of the positioning holes 87 is set to two groups, the two groups of positioning holes 87 are mounted on both sides of the sliding base 86 in the same axial direction, a permanent magnetic suction cup 88 is mounted on one end of the sliding base 86, the material of the permanent magnetic suction cup 88 is set to be neodymium iron boron material, and one end of the permanent magnetic suction cup 88 is magnetically attracted to the magnetic suction bar 92.

[0053] Then the control module 20 controls the electric push rod 2 85 to start, and after the electric push rod 2 85 is started, it pushes the sliding base 86 to slide downward. While the sliding base 86 slides, the disassembly plate 91 is driven to slide downward synchronously through the clamping effect of the positioning hole 87 and the insertion pin 93, and the magnetic attraction effect of the permanent magnetic suction cup 88 and the magnetic suction strip 92.

[0054] Then the operator rotates the turntable 84, and the rotation of the turntable 84 drives the bevel gear 83 to rotate synchronously, and the bevel gear 83 rotates and the meshing gear plate 82 rotates synchronously, and the meshing gear plate 82 rotates and drives the rotating base 81 to rotate synchronously, and the rotating base 81 rotates and drives the electric push rod 2 85, the sliding base 86, the positioning hole 87, the insertion pin 93 and the disassembly plate 91 to rotate synchronously, so that the insert tube 94 rotates away from the bottom end of the suction tube 71. After the inspection work is completed, the operator can remove the insertion pins 93 on both sides of the disassembly plate 91 from the inner wall of the positioning hole 87 to break the magnetic attraction between the permanent magnetic suction cup 88 and the magnetic suction strip 92. The operator can perform a secondary cleaning treatment on the surface of the insert tube 94 later.

[0055] By providing a rotating base 81, a positioning hole 87 and a permanent magnetic suction cup 88, the disassembly component 9 can be quickly disassembled and the disassembly component 9 can be disassembled and used alone. At the same time, the strong coercive force of neodymium iron boron is utilized to ensure the service life of the permanent magnetic suction cup 88 and reduce the cost of subsequent replacement and maintenance.

[0056] like Figures 10 to 12 As shown, the disassembly assembly 9 includes a disassembly plate 91, the cross section of the disassembly plate 91 is set to an "L"-shaped structure, a magnetic strip 92 is installed at one end of the disassembly plate 91, an insertion pin 93 is installed at one side of the disassembly plate 91, and the number of the insertion pins 93 is set to two groups. The two groups of insertion pins 93 are installed in the same axial direction on both sides of the disassembly plate 91. The surfaces of the two groups of insertion pins 93 are in contact with the inner wall of the positioning hole 87. The disassembly plate 91 is connected to the sliding base 86 through the insertion pins 93. An insert tube 94 is nested on the top of one side of the disassembly plate 91, and an insert tube 94 is installed on the inner wall of the insert tube 94. The convex ring 95 is inserted into a surface that contacts the surface of the double-groove retaining ring 710. The material of the inserted convex ring 95 is set to butadiene rubber. A gear ring 96 is sleeved on the middle surface of the insert tube 94. A flat gear 97 is meshed on one side of the gear ring 96. The flat gear 97 is installed at the bottom end of the inner wall of the disassembly plate 91. A micro motor 98 is installed on the top of the part of the disassembly plate 91 that extends out of the top of the flat gear 97. The micro motor 98 is installed on one side of the disassembly plate 91. A support plate 99 is installed on the bottom surface of the insert tube 94. The materials of the insert tube 94 and the support plate 99 are both set to polytetrafluoroethylene.

[0057] The cannula 94 and the support plate 99 enter below the blood level in the test tube 5. When the cannula 94 and the support plate 99 are close to the blood level in the test tube 5, the control module 20 controls the micro motor 98 to start. After the micro motor 98 is started, it drives the flat gear 97 to rotate synchronously. When the flat gear 97 rotates, the meshing gear ring 96 rotates, causing the gear ring 96 to rotate. Under the rotation of the gear ring 96, the cannula 94 and the support plate 99 are driven to rotate synchronously. Under the rotation of the support plate 99, the surface tension of the blood surface is destroyed to avoid agglomeration of the blood surface.

[0058] Then the control module 20 starts the electric slide rail 2 31, and under the action of the electric slide rail 2 31, the mounting bracket 32 ​​slides in the opposite direction of the electric slide rail 2 31 to reset. While the mounting bracket 32 ​​slides, it drives the suction tube 71 and the cannula 94 to leave the test tube 5, so that the cannula 94 and the support plate 99 are out of contact with the blood liquid surface in the test tube 5.

[0059] Subsequently, the control module 20 controls the electric push rod 2 85 to start. After the electric push rod 2 85 is started, it pushes the sliding base 86 to slide downward. While the sliding base 86 slides, the clamping effect of the positioning hole 87 and the insertion pin 93, as well as the magnetic attraction effect between the permanent magnetic suction cup 88 and the magnetic strip 92, drives the disassembly plate 91 to slide downward synchronously. While the disassembly plate 91 slides, it drives the insertion tube 94 to slide downward synchronously. While the insertion tube 94 slides, the insertion convex ring 95 on the inner wall of the insertion tube 94 is disengaged from the double-groove clamping ring 710, so that the insertion tube 94 is disengaged from the suction tube 71.

[0060] By providing the cannula 94 and the inserting convex ring 95 and cooperating with the effect of the suction component 7, the suction effect of blood is achieved. At the same time, the cannula 94 enters the blood liquid surface for suction to realize the division of the suction position. At the same time, by specially designing a support plate 99 at the bottom end of the cannula 94, when the cannula 94 enters below the blood liquid surface for suction, the blood liquid surface is damaged by the rotation effect of the support plate 99, so as to avoid the blood liquid surface from agglomerating and causing blockage during suction. At the same time, the excellent chemical stability of polytetrafluoroethylene and the property of almost no reaction with other substances are utilized to increase the service life of the cannula 94 and the support plate 99. At the same time, the dripping blood is collected by the support plate 99 to avoid secondary contamination caused by dripping blood.

[0061] The working principle of the technical solution provided by the present invention is as follows:

[0062] The operator first starts the electric slide rail 1 3 through the control module 20. Under the action of the electric slide rail 1 3, the mounting base 30 slides along the direction of the electric slide rail 1 3. While the mounting base 30 slides, it drives the electric push rod 1 33 and the rotating magnetic suction cup 34 to slide synchronously. At the same time, the mounting base 30 drives the suction tube 71 to slide synchronously to reach the top position of the inspection test tube 5. Then the control module 20 starts the electric slide rail 2 31. Under the action of the electric slide rail 2 31, the mounting bracket 32 ​​slides downward along the direction of the electric slide rail 2 31.

[0063] When the mounting bracket 32 ​​slides, it drives the suction tube 71 and the cannula 94 to approach and enter the interior of the test tube 5, so that the cannula 94 and the support plate 99 enter below the blood level in the test tube 5. When the cannula 94 and the support plate 99 approach the blood level in the test tube 5, the control module 20 controls the micro motor 98 to start. After the micro motor 98 is started, it drives the flat gear 97 to rotate synchronously. When the flat gear 97 rotates, the meshing gear ring 96 rotates, causing the gear ring 96 to rotate. Under the rotation action of the gear ring 96, the cannula 94 and the support plate 99 are driven to rotate synchronously. Under the rotation action of the support plate 99, the surface tension of the blood surface is destroyed to avoid agglomeration of the blood surface.

[0064] Subsequently, the control module 20 controls the electric push rod 33 to start, and the electric push rod 33 drives the rotating magnetic suction cup 34 to slide upward. While the rotating magnetic suction cup 34 slides, it drives the magnetic disk 74 to slide upward synchronously through magnetic adsorption. While the magnetic disk 74 slides, it drives the hollow push rod 73 and the piston disk 70 to slide upward synchronously, so that the piston disk 70 forms a suction effect in the internal cavity of the suction tube 71. Under the sliding suction action of the piston disk 70, the blood in the test tube 5 passes through the cannula 94 and enters the suction tube 71. While the piston disk 70 slides, it drives the output capillary 76 and the multiple groups of suction baffles 77 to slide synchronously. Through the array spacing effect between the multiple groups of suction baffles 77, the suction baffle 77 changes the flow state of the blood when the sucked blood passes through the output capillary 76 and the surface of the multiple groups of suction baffles 77, so as to avoid agglomeration during the blood suction process.

[0065] When the blood is drawn, the control module 20 controls the rotating magnetic suction cup 34 to rotate. While the rotating magnetic suction cup 34 rotates, the magnetic disk 74 is driven to rotate synchronously through magnetism. While the magnetic disk 74 rotates, the hollow push rod 73 and the piston disk 70 are driven to rotate synchronously. While the hollow push rod 73 rotates, the output capillary 76 and the multiple groups of suction baffles 77 are driven to rotate synchronously through the elastic telescopic rod 75. The surface of the clamping column 78 of the suction baffle 77 of the group of suction baffles 77 close to the elastic telescopic rod 75 among the multiple groups of suction baffles 77 rotates in accordance with the slide groove 720. While the clamping column 78 rotates, it enters the transverse channel in the middle of the slide groove 720, thereby realizing the clamping effect between the clamping column 78 and the slide groove 720. Under the clamping action of the clamping column 78 and the slide groove 720, this group of suction baffles 77 and the bottom plate 72 are kept in a clamping state.

[0066] Then the control module 20 starts the electric slide rail 2 31, and under the action of the electric slide rail 2 31, the mounting bracket 32 ​​slides in the opposite direction of the electric slide rail 2 31 to reset. While the mounting bracket 32 ​​slides, it drives the suction tube 71 and the cannula 94 to leave the test tube 5, so that the cannula 94 and the support plate 99 are out of contact with the blood liquid surface in the test tube 5.

[0067] Subsequently, the control module 20 controls the electric push rod 2 85 to start. After the electric push rod 2 85 is started, it pushes the sliding base 86 to slide downward. While the sliding base 86 slides, the clamping effect of the positioning hole 87 and the insertion pin 93, as well as the magnetic attraction effect between the permanent magnetic suction cup 88 and the magnetic strip 92, drives the disassembly plate 91 to slide downward synchronously. While the disassembly plate 91 slides, it drives the insertion tube 94 to slide downward synchronously. While the insertion tube 94 slides, the insertion convex ring 95 on the inner wall of the insertion tube 94 is disengaged from the double-groove clamping ring 710, so that the insertion tube 94 is disengaged from the suction tube 71.

[0068] Then the operator rotates the turntable 84, and the rotation of the turntable 84 drives the bevel gear 83 to rotate synchronously, and the bevel gear 83 rotates and the meshing gear plate 82 rotates synchronously, and the meshing gear plate 82 rotates and drives the rotating base 81 to rotate synchronously, and the rotating base 81 rotates and drives the electric push rod 2 85, the sliding base 86, the positioning hole 87, the insertion pin 93 and the disassembly plate 91 to rotate synchronously, so that the insert tube 94 rotates away from the bottom end of the suction tube 71. After the inspection work is completed, the operator can remove the insertion pins 93 on both sides of the disassembly plate 91 from the inner wall of the positioning hole 87 to break the magnetic attraction between the permanent magnetic suction cup 88 and the magnetic suction strip 92. The operator can perform a secondary cleaning treatment on the surface of the insert tube 94 later.

[0069] Subsequently, the control module 20 controls the electric slide rail 3 to start, and under the action of the electric slide rail 3, the mounting base 30 slides along the direction of the electric slide rail 3. While the mounting base 30 slides, it drives the electric push rod 33 and the rotating magnetic suction cup 34 to slide synchronously. At the same time, the mounting base 30 drives the suction tube 71 to slide synchronously to reach the top of the analysis equipment 6 at the top position of the inspection test tube 5.

[0070] The control module 20 controls the electric push rod 33 to start, and the electric push rod 33 drives the rotating magnetic suction cup 34 to slide downward. While the rotating magnetic suction cup 34 slides downward, it drives the magnetic disk 74 to slide downward synchronously through magnetic adsorption. While the magnetic disk 74 slides, it drives the hollow push rod 73 and the piston disk 70 to slide downward synchronously. At this time, one set of suction baffles 77 and the bottom plate 72 are kept in a clamping state. When the hollow push rod 73 slides downward, the inner wall of the hollow push rod 73 pushes the elastic telescopic rod 75 to contract. At the same time, the inner wall of the piston disk 70 is pushed by the hollow push rod 73. The piston disc 70 slides on the surface of the output capillary 76, and while sliding, it squeezes the blood drawn from the suction tube 71, causing the blood to enter the through hole 79 on the surface of the suction baffle 77 of the group closest to the elastic telescopic rod 75. At the same time, under the continuous squeezing action of the piston disc 70, the blood enters the output capillary 76 through the hard tube at the bottom of the through hole 79. After entering the output capillary 76, the blood falls from the bottom of the output capillary 76 into the analysis device 6 under the action of gravity. The operator can record and analyze the blood information detected by the analysis device 6 through the display device 2.
