Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a semi-automatic coagulation detection analyzer. Background Art

[0002] A coagulation detection analyzer is a medical device used clinically to measure the content of various components in human blood and quantify the results of biochemical analysis, providing reliable numerical basis for clinical diagnosis of various diseases of patients. Its working principle is to use optical, magnetic or fluidic technologies to detect and measure various parameters during the blood coagulation process to evaluate whether the patient's coagulation function is normal. During the use of existing coagulation detection analyzers, professional operators need to shake the test tubes containing the patient's blood samples before detection. However, when there are a large number of samples to be detected, manual shaking by the operator will cause certain fatigue to the operator's limbs, thus affecting the detection efficiency. At the same time, during the detection process, multiple reagents need to be added and shaken manually. Since it is difficult to achieve consistency in the shaking time and frequency each time, it will lead to certain errors in the detection results, and the manual processing process is relatively cumbersome. Therefore, the present application provides a semi-automatic coagulation detection analyzer to meet the requirements. Summary of the Invention

Furthermore, by setting up multiple groups of syringes, different reagents can be added to the test tube in sequence, and after adding each reagent, the test tube can be shaken to make the solution in the test tube more evenly mixed, so that the result of the patient's blood sample can be more accurate when the final test is performed.

[0017] By setting up a disinfection component and a rotating component, when the syringe injects the internal reagent into the test tube, the needle can be automatically disinfected. At the same time, the cotton roll can also be automatically reeled in, so that the needle can be disinfected after each use, avoiding the operator's frequent disinfection of the needle during actual operation.

[0018] When the rubber rod hits the guide plate, the test tube rotates and shakes, so that the blood sample and anticoagulant in the test tube are fully mixed. By shaking the test tube the same way each time, the consistency of the mixing of the blood sample and anticoagulant in each test tube is improved, and the mixing error caused by the difficulty in achieving consistency in time and frequency when shaking by hand, and the error in the test results caused by this, are prevented. The uniformity of the test results of the blood samples in each test tube is improved. At the same time, multiple groups of syringes can inject the same volume of reagent as required at the same time each time, so that the reaction time and concentration are more uniform, thereby improving the accuracy of detection.

[0040] Such as Figures 1 to 12As shown in the figure, an embodiment of the present invention provides a semi-automatic coagulation detection analyzer, including a detector 1. The detector 1 includes a detection box 13. A cover plate 101 is installed at the front end of the detector 1. Transmission rollers 12 are rotatably connected to the four corners of the detection box 13. The top of one of the transmission rollers 12 is fixedly connected to the output shaft of a servo motor 11. An auxiliary plate 2 is fixedly connected to the detection box 13. A clamping assembly 4 is arranged above the auxiliary plate 2. The clamping assembly 4 is used to clamp a detection test tube 5 which contains the blood sample of the patient to be detected. Above the detection test tube 5, there are three groups of adjacent syringes 3. The bottom of the syringe 3 is rotatably connected to a needle 31. The three groups of syringes 3 are arranged clockwise in sequence. The three groups of syringes 3 are respectively meshed with a rotating assembly 6. 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 to a disinfection assembly 7. 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. A detection sensor is arranged on the remaining side of the detection box 13. When the staff first opens the cover plate 101 and places the detection 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 drive the detection test tube 5 to move in the detector 1 at the same time. During the movement of the detection test tube 5, it will rotate and vibrate under the action of the auxiliary plate 2, so that the blood sample in the detection test tube 5 is mixed with the anticoagulant. When the detection test tube 5 moves to directly below the first syringe 3, the servo motor 11 stops rotating. The first syringe 3 inserts into the detection test tube 5 and injects the first reagent inside into the detection test tube 5. After the first syringe 3 finishes injecting, the servo motor 11 will continue to rotate, causing the detection test tube 5 to continue to move and rotate and vibrate again, so that the internal solution is fully mixed with the first reagent. When the detection test tube 5 moves to below the second syringe 3, the servo motor 11 will stop again. The second syringe 3 will inject the second reagent inside into the detection test tube 5. After the injection is completed, the detection test tube 5 will move to below the third syringe 3 under the action of the servo motor 11 and be injected with the third reagent. Finally, after the detection test tube 5 is mixed, it will stop 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.

[0041] In this embodiment, as 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. Activity doors are provided on the sides of the detector 1. By opening the activity doors, the state of the detection box 13 can be observed, and reagents in the three syringes 3 can be added.

[0042] As an implementation method in this embodiment, as Figures 3 to 8 shown, three groups of evenly spaced serrated structures are provided on the top of the auxiliary plate 2. A guide plate 21 is fixedly connected to the side of the auxiliary plate 2. Intermediate positions of the three sides of the auxiliary plate 2 are fixedly connected with backing plates 22 respectively. The backing plates 22 correspond to the syringes 3 one by one. The backing plates 22 are located directly below the syringes 3. The clamping assembly 4 includes a conveyor belt 41. A connecting column 42 is fixedly connected to the surface of the conveyor belt 41. A clamping plate 43 is arranged on one side of the connecting column 42. One side of the clamping plate 43 is fixedly connected to a second gear 432 through a rubber rod 431. The second gear 432 is connected to the connecting column 42 through a bearing 433. A test tube 5 is clamped on the clamping plate 43. A sealing cap 51 is arranged 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, the transmission roller 12 located below the servo motor 11 will rotate, so that the conveyor belt 41 rotates 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 test tube 5 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, the rubber rod 431 will quickly recover due to the loss of the action of the inclined surface. During this process, the test tube 5 will experience shaking. Through the rotation of the test tube 5 and the shaking of the test tube 5, the blood sample and anticoagulant in the test tube 5 are fully mixed.

[0043] In this embodiment, as Figures 4 to 8 shown, a plurality of guide plates 21 are provided. 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 the test tube 5 will shake during the rotation process, 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, at this time the bottom of the test tube 5 is located on the backing plate 22, and at this time the backing plate 22 provides support for the test tube 5, preventing the rubber rod 431 from bending.

[0044] As an implementation method in this embodiment, as Figures 9 to 12As shown, a piston 32 is slidably connected in the syringe 3. A group of trigger plates 321 with uniform intervals are fixedly connected to the top of the piston 32. An electric push rod 322 is fixedly connected to the top of the trigger plate 321. A hollow rod 33 is fixedly connected to the side of the syringe 3. One end of the hollow rod 33 is slidably connected to the detection box 13 in a limited manner. 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 in the hollow rod 33. One end of the trigger rod 332 is provided with an inclined surface. A first spring 333 is sleeved on the trigger rod 332. The inclined surface of the trigger rod 332 is located below the trigger plate 321. A first gear 311 is provided on the needle 31. The rotating assembly 6 includes an auxiliary roller 61. The auxiliary roller 61 is connected to a gear shaft 62 through a belt. A gear is provided at the top of the gear shaft 62. The auxiliary roller 61 is connected to a transmission roller 12 through a belt. The auxiliary roller 61 is rotatably connected in the detection box 13. The gear at the top of the gear shaft 62 is meshed with the first gear 311 of the needle 31. The length of the gear 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 cloth roll 72 is rotatably connected in the storage tank 71. The cotton cloth roll 72 in the storage tank 71 is soaked with disinfection alcohol. The other end of the cotton cloth roll 72 is located on a winding shaft 74 in a collection tank 73. A winding plate 75 is provided on one side of the winding shaft 74. Annularly arrayed ratchet teeth 741 are provided on the winding shaft 74. A ratchet wheel 742 is rotatably connected to the winding shaft 74. The ratchet wheel 742 is connected to the winding shaft 74 through the ratchet teeth 741 in a matching manner. One end of one side of the winding plate 75 is provided with a serrated structure with uniform intervals. A group of annularly arrayed serrated structures are provided on the side surface of the ratchet wheel 742. The ratchet wheel 742 is meshed with the winding plate 75. Both the storage tank 71 and the collection tank 73 are fixedly connected to one side of the detection box 13. One side of the cotton cloth roll 72 is closely attached to the needle 31. The length of the needle 31 is greater than the width of the cotton cloth roll 72. An inclined surface is provided on the top of the winding plate 75, and the inclined surface on the top of the winding plate 75 is fitted with the inclined surface at the bottom of the inclined block 331. One side of the winding plate 75 is slidably connected to the detection box 13. A second spring 751 is provided 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 a belt. When the auxiliary roller 61 rotates, the gear shaft 62 is driven to rotate through a belt. During the rotation of the gear shaft 62, the needle 31 is driven to rotate through the gear at the top, so that the needle 31 can rotate on one side of the cotton cloth roll 72. When the test tube 5 is located below the syringe 3 and the servo motor 11 stops rotating, the needle 31 also stops rotating. At this time, the electric push rod 322 extends and pushes the trigger plate 321.

[0045] 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 descend synchronously with the syringe 3. When the hollow rod 33 moves to the bottom of the chute on the detection box 13, the hollow rod 33 cannot continue to move downward, and the syringe 3 cannot move. At this time, the needle 31 is inserted into the sealing cap 51. As the electric push rod 322 continues to extend, the trigger plate 321 will press against the inclined surface of the trigger rod 332 and gradually press the trigger rod 332 into the hollow rod 33. After 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 will also be injected into the test tube 5. When the electric push rod 322 contracts, the trigger rod 332 will always be stuck between the two trigger plates 321. During the upward movement, 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 press against 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 wheel 742 to rotate. When the ratchet wheel 742 rotates, it will drive the winding shaft 74 to rotate through the ratchet pawl 741. When the winding shaft 74 rotates, the cotton cloth roll 72 will be wound, so that the clean alcohol cotton cloth in the storage tank 71 contacts the needle 31. When the hollow rod 33 moves upward, the winding plate 75 will move in the reverse direction under the action of the second spring 751 and drive the ratchet wheel 742 to reverse. At this time, since the ratchet wheel 742 reverses, it will not drive the winding shaft 74 to rotate through the ratchet pawl 741, so the winding shaft 74 remains stationary. When the test tube 5 moves, the needle 31 will rotate against the alcohol cotton cloth under the action of the servo motor 11, thereby disinfecting the needle 31.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] When the staff first opens the cover plate 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 starts to rotate under the action of the servo motor 11 and simultaneously 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 directly below the first syringe 3, the servo motor 11 stops rotating. The first syringe 3 inserts into the test tube 5 and injects the first reagent inside into the test tube 5. After the first syringe 3 finishes injecting, the servo motor 11 will continue to rotate, causing the test tube 5 to continue to move and rotate and vibrate again, so that the internal solution is fully mixed with the first reagent. When the test tube 5 moves below the second syringe 3, the servo motor 11 will stop again. The second syringe 3 will inject the second reagent into the test tube 5. After the injection is completed, the test tube 5 will move below the third syringe 3 under the action of the servo motor 11 and be injected with the third reagent. Finally, after the test tube 5 is mixed, it will stop on one side of the detection sensor. When the detection sensor inside the detector 1 finishes detecting, 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 the initial position under the action of the servo motor 11. At this time, the operator can remove the tested test tube 5.

[0048] At the same time when the servo motor 11 rotates, the drive roller 12 located below the servo motor 11 will rotate, so that the conveyor belt 41 rotates 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 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, the rubber rod 431 will quickly recover due to the loss of the action of the inclined surface. During this process, the test tube 5 will experience shaking. Through the 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. When the servo motor 11 rotates, the drive roller 12 will drive the auxiliary roller 61 to rotate through the belt. When the auxiliary roller 61 rotates, it will drive the gear shaft 62 to rotate through the belt. During the rotation of the gear shaft 62, it will drive the needle 31 to rotate through the gear at the top, so that the needle 31 can rotate on one side of the cotton roll 72.

[0049] When the test tube 5 is located below the syringe 3 and 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. 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 descend synchronously with the syringe 3. When the hollow rod 33 moves to the bottom of the chute on the detection box 13, the hollow rod 33 cannot continue to move downward, and the syringe 3 cannot move. At this time, the needle 31 inserts into the sealing cap 51. As the electric push rod 322 continues to extend, the trigger plate 321 will squeeze on the inclined surface of the trigger rod 332 and gradually press the trigger rod 332 into the hollow rod 33. After 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 be stuck between the two trigger plates 321. At this time, the electric push rod 322 stops moving, and the reagent in the syringe 3 will also be injected into the test tube 5. When the electric push rod 322 contracts, the trigger rod 332 will always be stuck between the two trigger plates 321. During the upward movement, 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 squeeze 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 wheel 742 to rotate. When the ratchet wheel 742 rotates, it will drive the winding shaft 74 to rotate through the ratchet pawl 741. When the winding shaft 74 rotates, it will wind the cotton cloth roll 72, so that the clean alcohol cotton cloth in the storage tank 71 contacts the needle 31. When the hollow rod 33 moves upward, the winding plate 75 will move in the reverse direction under the action of the second spring 751 and drive the ratchet wheel 742 to reverse. At this time, since the ratchet wheel 742 reverses, it will not drive the winding shaft 74 to rotate through the ratchet pawl 741. Therefore, the winding shaft 74 remains stationary. When the test tube 5 moves, the needle 31 will rotate against the alcohol cotton cloth under the action of the servo motor 11, so as to disinfect the needle 31.
