Description

Technical Field

[0002] A coagulation detection analyzer is a medical device clinically used to measure the content of various components in human blood and quantitative biochemical analysis results, providing a reliable digital basis for clinical diagnosis of various diseases in patients. Its working principle is to use optical, magnetic or fluid technology to detect and measure various parameters in the blood coagulation process to evaluate whether the patient's coagulation function is normal. During the use of existing coagulation detection analyzers, professional operators are required to shake the test tubes containing patient blood samples before testing.

[0026] like Figures 1 to 12As shown, an embodiment of the present invention provides a semi-automatic coagulation detection analyzer, including a detector 1, wherein the detector 1 includes a detection box 13, a cover plate 101 is installed at the front end of the detector 1, and transmission rollers 12 are rotatably connected to the four corners of the detection box 13, and the top of one of the transmission rollers 12 is fixedly connected to the output shaft of the servo motor 11, and an auxiliary plate 2 is fixedly connected to the detection box 13, and a clamping assembly 4 is arranged above the auxiliary plate 2, and the clamping assembly 4 is used to clamp a detection test tube 5, and the detection test tube 5 contains blood to be tested by the patient, and three groups of adjacent syringes 3 are arranged above the detection test tube 5, and the bottom of the syringe 3 is rotatably connected to The three groups of syringes 3 are arranged in sequence clockwise, and the three groups of syringes 3 are respectively meshed and connected with a rotating assembly 6, and the rotating assembly 6 is used to rotate the needle 31 of the syringe 3. The bottoms of the three groups of syringes 3 are respectively slidably connected with a disinfection assembly 7, and the disinfection assembly 7 is used to disinfect the needle 31 of the syringe 3. The three groups of syringes 3 are respectively located on different sides of the detection box 13, and the remaining side of the detection box 13 is provided with a detection sensor. When the staff first opens the cover 101 and puts the test tube 5 containing the patient's blood sample on the clamping assembly 4, the servo motor 11 starts to rotate. When the servo motor 11 rotates, the clamping assembly 4 will The motor 11 starts to rotate under the action of the test tube 5, and at the same time drives the test tube 5 to move in the detector 1. During the movement of the test tube 5, it will rotate and vibrate under the action of the auxiliary plate 2, so that the blood sample in the test tube 5 is mixed with the anticoagulant. When the test tube 5 moves to just below the first syringe 3, the servo motor 11 stops rotating, the first syringe 3 is inserted into the test tube 5, and the first reagent inside is injected into the test tube 5. When the first syringe 3 has finished injecting, the servo motor 11 will continue to rotate, so that the test tube 5 continues to move, and rotates and vibrates again, so that the solution inside is fully mixed with the first reagent. When the detection test tube 5 moves to the bottom of the second syringe 3, the servo motor 11 will stop again, and the second syringe 3 will inject the second reagent inside into the detection test tube 5. When the injection is completed, the detection test tube 5 will move to the bottom of the third syringe 3 under the action of the servo motor 11 and be injected with the third reagent. Finally, after mixing, the detection test tube 5 will stay on one side of the detection sensor. When the detection sensor finishes the detection, the detection result will be displayed on the display screen at the top of the detector 1. At the same time, the detection test tube 5 will return to the initial position under the action of the servo motor 11. At this time, the operator can remove the detected detection test tube 5.

[0027] In this embodiment, if Figures 1 to 7As shown, the top of the detector 1 is a numerical control operation area, and the operator can adjust the rotation speed of the servo motor 11 according to different situations. The sides of the detector 1 are provided with movable doors, and the state of the detection box 13 can be observed and the reagents in the three syringes 3 can be added by opening the movable doors.

[0028] As an implementation method in this embodiment, Figures 3 to 8 As shown, the top of the auxiliary plate 2 is provided with three groups of uniformly spaced serrated structures, the side of the auxiliary plate 2 is fixedly connected with a guide plate 21, the middle positions of the three sides of the auxiliary plate 2 are fixedly connected with pads 22, the pads 22 and the syringes 3 correspond one to one, and the pads 22 are located directly below the syringes 3. The clamping assembly 4 includes a conveyor belt 41, the surface of the conveyor belt 41 is fixedly connected with a connecting column 42, a clamping plate 43 is provided on one side of the connecting column 42, one side of the clamping plate 43 is fixedly connected to the second gear 432 through a rubber rod 431, and the second gear 432 is connected to the connecting column 42 through a bearing 433. The clamping plate 43 clamps a test tube 5, and a sealing cover 51 is provided on the top of the test tube 5. The inner side of the conveyor belt 41 is connected to four transmission rollers 12. When the servo motor 11 rotates, When the rubber rod 431 hits the guide plate 21, the rubber rod 431 moves on the inclined surface at the top of the guide plate 21 and gradually bends. When the rubber rod 431 moves to the end of the inclined surface, the rubber rod 431 loses the effect of the inclined surface and thus quickly recovers. In this process, the test tube 5 experiences shaking. Through the self-rotation of the test tube 5 and the shaking of the test tube 5, the blood sample and the anticoagulant in the test tube 5 are fully mixed.

[0029] In this embodiment, if Figures 4 to 8 As shown, the guide plates 21 are provided with a plurality of them. Whenever the syringe 3 injects the internal reagent into the test tube 5, the rubber rod 431 will come into contact with the guide plate 21, and make the test tube 5 shake during the rotation, thereby increasing the mixing degree between the solution and the reagent in the test tube 5. When the syringe 3 inserts the needle 31 into the test tube 5, the bottom of the test tube 5 is located on the pad 22. At this time, the pad 22 provides support for the test tube 5, thereby preventing the rubber rod 431 from bending.

[0030] As an implementation method in this embodiment, Figures 9 to 12As shown, the syringe 3 is slidably connected with a piston 32, the top of the piston 32 is fixedly connected with a group of trigger plates 321 with uniform intervals, the top of the trigger plate 321 is fixedly connected with an electric push rod 322, the side of the syringe 3 is fixedly connected with a hollow rod 33, one end of the hollow rod 33 is limitedly slidably connected to the detection box 13, an inclined block 331 is fixedly connected to the hollow rod 33, the opening of the hollow rod 33 is located above the piston 32, a trigger rod 332 is slidably connected to the hollow rod 33, one end of the trigger rod 332 is provided with an inclined surface, the trigger rod 332 is sleeved with a first spring 333, the inclined surface of the trigger rod 332 is located below the trigger plate 321, and the needle 31 is provided with a first Gear 311, the rotating assembly 6 includes an auxiliary roller 61, the auxiliary roller 61 is connected to the gear shaft 62 through a belt, a gear is arranged on the top of the gear shaft 62, the auxiliary roller 61 is connected to the driving roller 12 through a belt, the auxiliary roller 61 is rotatably connected in the detection box 13, the top of the gear shaft 62 is meshed with the first gear 311 of the needle 31 through a gear, the gear length on the gear shaft 62 is greater than the length of the first gear 311, the disinfection assembly 7 includes a storage tank 71, a cotton roll 72 is rotatably connected in the storage tank 71, the cotton roll 72 in the storage tank 71 is not immersed in disinfection alcohol, the other end of the cotton roll 72 is located on the reel 74 in the collection tank 73, and one side of the reel 74 A winding plate 75 is provided, and a circular array of ratchet pawls 741 is provided on the winding shaft 74. A ratchet 742 is rotatably connected to the winding shaft 74. The ratchet 742 is connected to the winding shaft 74 through the ratchet 741. One end of one side of the winding plate 75 is provided with a serrated structure with uniform intervals. The side of the ratchet 742 is provided with a group of serrated structures in an annular array. The ratchet 742 is meshed and connected with the winding plate 75. The storage tank 71 and the collection tank 73 are both fixedly connected to one side of the detection box 13. One side of the cotton roll 72 is close to the needle 31. The length of the needle 31 is greater than the width of the cotton roll 72. The top of the winding plate 75 is provided with an inclined surface, which drives the inclined surface at the top of the winding plate 75 to contact the bottom of the inclined block 331. The inclined surface of the winding plate 75 fits together, one side of the winding plate 75 is slidably connected to the detection box 13, and a second spring 751 is arranged between the winding plate 75 and the detection box 13. When the servo motor 11 rotates, the transmission roller 12 drives the auxiliary roller 61 to rotate through the belt. When the auxiliary roller 61 rotates, the gear shaft 62 is rotated through the belt. During the rotation of the gear shaft 62, the needle 31 is driven to rotate through the top gear, so that the needle 31 can rotate on one side of the cotton cloth roll 72. When the detection test tube 5 is located below the syringe 3, when the servo motor 11 stops rotating, the needle 31 also stops rotating at the same time. At this time, the electric push rod 322 extends and pushes the trigger plate 321.

[0031] When the syringe 3 is in the state of being pressed down, the trigger plate 321 is pressed against the inclined surface of the trigger rod 332, and the trigger rod 332 is gradually pressed into the hollow rod 33. When the piston 32 moves downward for a certain distance, the trigger plate 321 is separated from the inclined surface of the trigger rod 332, and the trigger rod 332 is ejected under the action of the first spring 333 and is stuck between the two trigger plates 321. At this time, the electric push rod 322 stops moving, and the reagent in the syringe 3 is also injected into the test tube 5. When the electric push rod 322 is contracted, the trigger rod 332 is always stuck between the two trigger plates 321. When the syringe 3 moves downward, the inclined block 331 on the hollow rod 33 will be pressed on the winding plate 75, and the winding plate 75 will move under the action of the inclined block 331. When the winding plate 75 moves, the winding plate 75 will drive the ratchet 742 to rotate. When the ratchet 742 rotates, the winding shaft 74 will rotate through the pawl 741. When the winding shaft 74 rotates, the cotton cloth roll 72 will be rolled up, so that the clean alcohol cotton cloth in the storage tank 71 will contact the needle 31. When the hollow rod 33 moves upward, the winding plate 75 will move in the opposite direction under the action of the second spring 751, and drive the ratchet 742 to reverse. At this time, due to the reverse rotation of the ratchet 742, the winding shaft 74 will not be driven to rotate through the pawl 741, so the winding shaft 74 remains stationary. When the test tube 5 moves, the needle 31 will rotate on the alcohol cotton cloth under the action of the servo motor 11, thereby disinfecting the needle 31.

[0032] The working principle of the technical solution provided by the present invention is as follows: When the staff first opens the cover 101 and places the test tube 5 containing the patient's blood sample on the clamping assembly 4, the servo motor 11 starts to rotate. When the servo motor 11 rotates, the clamping assembly 4 will start to rotate under the action of the servo motor 11, and at the same time drive the test tube 5 to move in the detector 1. During the movement of the test tube 5, it will rotate and vibrate under the action of the auxiliary plate 2, so that the blood sample in the test tube 5 is mixed with the anticoagulant. When the test tube 5 moves to just below the first syringe 3, the servo motor 11 stops rotating, the first syringe 3 is inserted into the test tube 5, and the first reagent inside is injected into the test tube 5. When the first syringe 3 is injected, the servo motor 11 will continue to rotate to make the test tube 5 move. The test tube 5 then moves, and rotates and vibrates again to fully mix the solution inside with the first reagent. When the test tube 5 moves to the bottom of the second syringe 3, the servo motor 11 will stop again, and the second syringe 3 will inject the second reagent inside into the test tube 5. When the injection is completed, the test tube 5 will move to the bottom of the third syringe 3 under the action of the servo motor 11, and be injected with the third reagent. Finally, after mixing, the test tube 5 will stay on one side of the detection sensor. When the detection sensor inside the detector 1 is finished, the detection result will be displayed on the display screen at the top of the detector 1. At the same time, the test tube 5 will return to its initial position under the action of the servo motor 11. At this time, the operator can remove the tested test tube 5.

[0033] At the same time, when the servo motor 11 rotates, the transmission roller 12 located below the servo motor 11 will rotate, so that the conveyor belt 41 will rotate around the detection box 13. When the conveyor belt 41 rotates, the second gear 432 will rotate under the action of the auxiliary plate 2. When the second gear 432 rotates, the detection test tube 5 located on the clamping plate 43 will rotate synchronously with the second gear 432. When the rubber rod 431 hits the guide plate 21, the rubber rod 431 will move on the inclined surface at the top of the guide plate 21 and gradually bend. When the rubber rod 431 moves to the end of the inclined surface When the servo motor 11 rotates, the transmission roller 12 drives the auxiliary roller 61 to rotate through the belt. When the auxiliary roller 61 rotates, the gear shaft 62 is rotated through the belt. During the rotation of the gear shaft 62, the needle 31 is driven to rotate through the gear on the top, so that the needle 31 can rotate on one side of the cotton cloth roll 72.

[0034] When the test tube 5 is located below the syringe 3, the servo motor 11 stops rotating, and the needle 31 also stops rotating. At this time, the electric push rod 322 extends and pushes the trigger plate 321. At this time, since the inclined surface of the trigger rod 332 is stuck between the piston 32 and the trigger plate 321, the trigger plate 321 will drop synchronously with the syringe 3. When the hollow rod 33 moves to the bottom of the slide groove on the detection box 13, the hollow rod 33 cannot move downward further, and the syringe 3 cannot move. At this time, the needle 31 is inserted into the sealing cover 5. 1, as the electric push rod 322 continues to extend, the trigger plate 321 will be pressed on the inclined surface of the trigger rod 332, and gradually press the trigger rod 332 into the hollow rod 33. When the piston 32 moves downward for a certain distance, the trigger plate 321 will separate from the inclined surface of the trigger rod 332, and the trigger rod 332 will pop out under the action of the first spring 333 and get stuck between the two trigger plates 321. At this time, the electric push rod 322 stops moving, and the reagent in the syringe 3 is also injected into the test tube 5. When the electric push rod 322 shrinks, the trigger plate 321 will be pressed against the inclined surface of the trigger rod 332. During the process of the syringe 3 rising, the trigger rod 332 will always be stuck between the two trigger plates 321. During the rising process, the volume of the reagent inside the syringe 3 remains unchanged. When the syringe 3 moves downward, the inclined block 331 on the hollow rod 33 will be pressed on the winding plate 75. The winding plate 75 will move under the action of the inclined block 331. When the winding plate 75 moves, the winding plate 75 will drive the ratchet 742 to rotate. When the ratchet 742 rotates, the winding shaft 74 will rotate through the ratchet 741. When the winding shaft 74 rotates, , the cotton cloth roll 72 will be rolled up, so that the clean alcohol cotton cloth in the storage tank 71 will contact the needle 31. When the hollow rod 33 moves upward, the winding plate 75 will move in the opposite direction under the action of the second spring 751, and drive the ratchet 742 to reverse. At this time, due to the reverse rotation of the ratchet 742, the winding shaft 74 will not be driven to rotate through the pawl 741, so the winding shaft 74 remains stationary. When the test tube 5 moves, the needle 31 will rotate on the alcohol cotton cloth under the action of the servo motor 11, thereby disinfecting the needle 31.
