Description

Technical Field

[0001] This invention relates to the field of elasticity calibration equipment technology, and more specifically, to an intelligent elasticity calibration instrument. Background Technology

[0002] Thromboelastography is an analytical technique that monitors the entire dynamic process of blood coagulation, including platelet aggregation, coagulation, and fibrinolysis. Its principle is based on the physical properties of the blood clot formed during the coagulation process, which determine whether it has normal coagulation function. The device that collects the coagulation state of blood and generates a thromboelastogram is called a thromboelastograph.

[0003] In a thromboelastography instrument, the sensor component responsible for detecting changes in blood coagulation status over time is the most important core component of the instrument series. Its core idea is a torque meter that detects the coagulation strength of blood clots. The accuracy of this sensor directly affects the final measurement results and even the clinician's interpretation of the results. However, because the torque during the formation of blood clots is too small, there is no commercially available torque meter that can be directly used for the calibration and excision of this type of sensor. Therefore, the two common methods for calibrating this type of sensor are currently the use of an elastomer and the use of quality control materials.

[0004] Currently, traditional elastic force gauges only have a fixed torque output and can only perform one-point calibration. They cannot perform two-point linear calibration, let alone multi-point continuous linear calibration. The calibration results can only guarantee accuracy at and near the elastic force reference value, while the results for values ​​far from the reference value are difficult to guarantee.

[0005] Furthermore, in clinical practice, most studies currently require comparative experiments on different devices. This necessitates calibrating two elastogramr devices to the same state beforehand. Typically, identical force meters are used to calibrate the two devices being compared. However, equipment in research institutions or hospitals is generally not allowed to be calibrated, and its accuracy cannot be guaranteed. Therefore, a method must be used to obtain the elasticity curves of these devices and copy them to the device being compared, allowing the comparative experiment to proceed under identical conditions. Existing traditional force meters are therefore unable to perform this function of measuring the torque curve of the thromboelastogramr's detection head.

[0006] Meanwhile, while quality control products can simulate the blood coagulation process and output continuous coagulation signals (the output value of the elastometer is a constant, appearing as a straight line in the output index), they can only simulate a portion of the samples. Furthermore, the target value of the quality control product is a range, with a certain degree of error, including inter-bottle and inter-batch variations. It cannot accurately reproduce a specific experimental process. For special samples (such as hypocoagulability, hypercoagulability, hyperfibrinolysis, signal interference, and signal jitter), it cannot be simulated, nor can it comprehensively evaluate all the curve characteristics of a new device.

[0007] In summary, if a calibration device could be developed that could achieve multiple torque outputs, linearly calibrate the elastogram sensor, simulate various abnormal sample curve outputs, and scan the elasticity curve of a reference device before comparative experiments, it would undoubtedly improve product quality and production efficiency for factories, significantly enhance R&D efficiency for scientific research, and not only improve equipment accuracy but also significantly reduce training costs for clinicians, providing them with a solid and reliable standard. Therefore, this application provides an intelligent elasticity calibration instrument to improve this situation. Summary of the Invention

[0010] 2. Technical Solution

[0011] To solve the above problems, the present invention adopts the following technical solution.

[0012] An intelligent elasticity calibration instrument includes a base. Three equally angularly distributed horizontal adjustment screws are threaded to the upper end of the base. These screws pass through the lower side of the base, and a shock-absorbing base is located at the lower end of each screw. A three-axis fine-tuning platform is mounted on the upper end of the base, positioned at the center of the three horizontal adjustment screws. An X-axis adjustment handle, a Y-axis adjustment handle, and a Z-axis adjustment handle are respectively mounted on the front, left, and right ends of the three-axis fine-tuning platform. A detection head module is bolted to the upper end of the three-axis fine-tuning platform. A drive sensor is installed inside the detection head module on the side away from the three-axis fine-tuning platform. A coupling is inserted between the inner walls of the drive sensors. A level is fixedly connected to the bottom inner end of the detection head module, located in front of the drive sensors.

[0013] Furthermore, the testing assembly includes a device under test mounted on the upper end of the coupling, a supporting base plate at the lower end of the device under test, three evenly distributed supporting columns at the upper end of the supporting base plate, a bearing plate fixedly connected to the upper end of the supporting columns, the bearing plate being located on the lower side of the coupling, and the rear end face of the bearing plate being fixedly connected to the inner wall of the device under test, two symmetrically distributed storage holes being opened at the upper end of the bearing plate, a constant temperature plate being provided between the inner walls of the storage holes, two symmetrically distributed telescopic rods being inserted into the upper end of the constant temperature plate, both of the telescopic rods being located on both sides of the coupling, and the upper end of the telescopic rods being fixedly connected to the inner bottom end of the device under test.

[0014] Furthermore, all three support columns are made of a combination of stainless steel and rubber layers, wherein the upper and lower ends of the support columns are made of stainless steel plates, and the middle end is fixedly connected with a rubber sleeve.

[0015] Furthermore, the three support columns are arranged at equal angles on the upper part of the support base plate, with two of the support columns located on the lower side of the bearing plate and on the same horizontal plane, and the other support column located on the lower side of the device under test.

[0016] Furthermore, the motor driving the sensor is a voice coil motor based on magnetically encoded feedback.

[0017] Furthermore, a wire connector is inserted inside the connector socket, and the wire connector is electrically connected to a control circuit board via a wire harness. The outer end of the control circuit board is electrically connected to host computer software.

[0018] Furthermore, the shock-absorbing base includes a first connecting plate located at the lower end of the horizontal adjusting screw. The upper end of the first connecting plate has multiple evenly distributed through holes. The first connecting plate is fixedly connected to the horizontal adjusting screw by bolts inserted between the inner walls of the through holes. A shock-absorbing pad is fixedly connected to the lower side of the first connecting plate. A rubber support is located on the lower side of the shock-absorbing pad. A damper is installed between the inner wall of the shock-absorbing pad and the rubber support. Multiple superimposed high-damping vibration-isolating rubber pads are fixedly connected between the shock-absorbing pad and the inner wall of the rubber support. The high-damping vibration-isolating rubber pads are sleeved on the outside of the damper.

[0019] Furthermore, a protective sleeve is fixedly connected to the outer end of the high-damping vibration isolation rubber pad, and the protective sleeve is made of rubber material.

[0020] Furthermore, the thermostatic disc is sleeved on the outside of the telescopic rod, and the lower end of the telescopic rod is threaded with a limit nut, with the thermostatic disc located above the limit nut.

[0021] Furthermore, the support base plate is made of stainless steel, and the upper end of the support base plate has multiple evenly distributed mounting holes.

[0022] 3. Beneficial effects

[0023] Compared with the prior art, the advantages of this invention are:

[0024] (1) When using this solution, the traditional elastic graph instrument calibration is performed using a fixed-value elastic gauge, which can only calibrate one fixed point. However, existing methods require at least two points to achieve linear calibration. Furthermore, due to differences in the materials and processes of the sensor (suspension wire), single-point calibration may have significant errors. In contrast, the calibration instrument of this invention can generate standard values ​​for multiple points, enabling not only linear calibration at two points but also image calibration at multiple points. This effectively improves production efficiency and provides a better user experience for elastic graph instrument calibration.

[0025] (2) When this scheme is used, it can also act as a torque function generator, that is, it can reproduce the blood coagulation process based on known blood sample specimens, and be used to test the sensitivity of the equipment in ultra-low coagulation state and the overload resistance performance in ultra-high coagulation state.

[0026] (3) When using this solution, it can scan the characteristics of the suspension wire of the transplanted thromboelastography instrument and can also replicate and calibrate to another device based on the scanned pattern, thereby improving the efficiency of the detection work.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Currently, the following two methods are commonly used when calibrating sensor components:

[0040] 1. The spring gauge is a standard tool and a constant spring force output structure based on a torsion spring. When in use, the spring gauge is connected in series between the detection probe and the constant temperature plate to measure the maximum torque on the probe when it is passively rotated 4°45′. By comparing the detected torque value with the standard value of the spring gauge, the calibration purpose is achieved by adjusting the internal gain coefficient.

[0041] 2. Use quality control materials for calibration. The process of blood clotting is simulated by the quality control materials. The obtained index is compared with the target value of the quality control materials, and then the sensor is adjusted. Since the CV value of the quality control materials is usually greater than 5%, the calibration accuracy of this method is not high.

[0042] Meanwhile, the detection principle of thromboelastography based on the suspended wire technology is as follows:

[0043] like Figure 6 As shown, the core component is the suspension wire, which is an elastic torsion wire that functions similarly to a spring. The upper end of the suspension wire is fixed, and the lower end is connected to the probe and the cup lid. The test cup contains the sample to be tested. During testing, the base rotates the test cup back and forth at a speed of 4°45′ every 10 seconds, with the axis of the test cup as the center. The blood sample in the test cup acts as a coupling agent between the test cup and the test cup lid. As the blood gradually coagulates, the shear force transmitted from the test cup to the test cup lid through the blood increases, and the rotation angle of the test cup lid gradually increases. The envelope of the rotation angle amplitude of the test cup lid is output to the display device. This envelope is the thromboelastography.

[0044] And the principle of thromboelastography detection based on magnetic coding technology:

[0045] The core technology of the thromboelastography sensor using magnetic encoding is a miniature voice coil motor that provides position and angle feedback. This voice coil motor can output precise values ​​down to the angle and torque. The motor drives the detection spindle, causing the cup lid to rotate periodically. The rotation angle and angular velocity of the spindle are accurately measured. By calculating the change in driving current, the changes in blood viscosity throughout the dynamic process of platelet aggregation, coagulation, and fibrinolysis are precisely calculated. The envelope of the effective current value is equivalent to a thromboelastography. The principle can be found in Chinese patent document CN107976382A, "Detection Probe and Blood Sample Detection Device".

[0046] Example 2:

[0047] Currently, there is no existing calibration device that can achieve multiple torque outputs, linear calibration of elastogram sensor, simulate various abnormal sample curve outputs, and scan the elasticity curve of reference device before comparative experiments. This embodiment provides an intelligent elasticity calibrator that integrates elasticity curve sampling, elasticity curve calibration, and elasticity curve function output for the detection head sensor of a thrombosis elastogram.

[0048] It mainly achieves the integration of elastic curve sampling, elastic curve calibration, and elastic curve function output through three applications. The first is the elastic curve sampling principle. This scheme connects the calibrator and the detection head of the sampled device in series. By changing the angle output of the calibrator, the main shaft of the detection head of the tested device is passively rotated. The rotation angle linearly and stably increases from 0° to 4°45′. Within each scale change, the elasticity calibrator sensor samples and detects the torque, thus obtaining the linear correspondence between the angle and torque diagram of the thromboelastography detection head sensor of the scanned device.

[0049] 2. The principle of continuous linear calibration of elastic curves involves connecting the calibrator and the detection head of the device being calibrated in series, allowing the elastic calibrator to continuously output several standard values. Each standard value corresponds to a measured value at that angle. By observing multiple points, a linear compensation function is established to achieve linear calibration of the device being calibrated.

[0050] 3. Elasticity curve function output: Connect the calibrator and the detection head of the simulated device in series, so that the elasticity calibrator drives the main shaft of the rotating simulation device to rotate in an orderly manner according to a predetermined angle and torque, in order to simulate the coagulation process of some special specimens. In this case, the elasticity calibrator is a torque function generator.

[0051] Therefore, in the three applications mentioned above, this solution enables the elasticity calibrator to function as both a driver and a sensor. The ability to freely switch between these two roles stems from the fact that its driving and detection device is also a magnetically encoded voice coil motor, resulting in an unprecedented user experience for elasticity grapher calibration. Traditional elasticity grapher calibration uses a fixed-value elasticity gauge, calibrating only one fixed point. However, current applications require at least two points for linear calibration. Furthermore, due to differences in sensor (suspension wire) materials and manufacturing processes, single-point calibration may have significant errors. The calibrator of this invention can generate multi-point standard values, enabling not only two-point linear calibration but also multi-point image calibration, effectively improving production efficiency.

[0052] This invention can also function as a torque function generator, which can reproduce the blood coagulation process based on known blood samples, and be used to test the sensitivity of the device in ultra-low coagulation state and its overload resistance in ultra-high coagulation state.

[0053] Furthermore, this invention can scan the characteristics of the suspension wire of a transplanted thromboelastography instrument and can also replicate and calibrate the scanned pattern onto another device.

[0054] Example 3:

[0055] Please see Figure 1-5 This embodiment of Example 2 describes an intelligent elasticity calibration instrument for a thromboelastography sensor, integrating elastic curve sampling, elastic curve calibration, and elastic curve function output. The intelligent elasticity calibration instrument includes a base 1. Three equally angled horizontal adjusting screws 2 are threaded to the upper end of the base 1, passing through the lower side of the base 1. A shock-absorbing base is located at the lower end of each horizontal adjusting screw 2. A three-axis fine-tuning platform 7 is mounted on the upper end of the base 1, positioned at the center of the three horizontal adjusting screws 2. The front end, left end, and right end of the three-axis fine-tuning platform 7 are... The three-axis fine-tuning platform 7 is equipped with an X-axis adjustment handle 3, a Y-axis adjustment handle 4, and a Z-axis adjustment handle 5. The upper end of the three-axis fine-tuning platform 7 is fixedly connected to a detection head module 6 by bolts. The inner wall bottom of the detection head module 6 away from the three-axis fine-tuning platform 7 is equipped with a drive sensor 8. A coupling 9 is inserted between the inner walls of the drive sensors 8. A level 71 is fixedly connected to the inner bottom of the detection head module 6. The level 71 is located in front of the drive sensor 8. A connector socket 10 is installed on the inner bottom of the detection head module 6 near the three-axis fine-tuning platform 7. A detection component is provided on the upper end of the coupling 9.

[0056] The testing assembly includes a device under test (DUT) 11 mounted on the upper end of a coupling 9. A support base plate 12 is provided at the lower end of the DUT 11. Three evenly distributed support columns 13 are provided at the upper end of the support base plate 12. A bearing plate 14 is fixedly connected to the upper end of the support columns 13. The bearing plate 14 is located on the lower side of the coupling 9, and the rear end face of the bearing plate 14 is fixedly connected to the inner wall of the DUT 11. Two symmetrically distributed storage holes 15 are opened at the upper end of the bearing plate 14. A constant temperature plate 17 is provided between the inner walls of the storage holes 15. Two symmetrically distributed telescopic rods 16 are inserted into the upper end of the constant temperature plate 17. Both telescopic rods 16 are located on both sides of the coupling 9. The upper end of the telescopic rods 16 is fixedly connected to the inner bottom end of the DUT 11.

[0057] In this design, three X-axis adjustment handles 3 are installed on top of the base 1, which is made of steel plate, to adjust the level of the base 1. During adjustment, a level 71 can be used to verify the levelness. Furthermore, a three-axis fine-tuning platform 7 is installed above the base 1, with X-axis adjustment handles 3, Y-axis adjustment handles 4, and Z-axis adjustment handles 5 installed on its front, left, and right sides respectively. This allows the three-axis fine-tuning platform 7 to be adjusted via the X-axis and Y-axis adjustment handles 3 and 5 respectively. Under the action of the joint handle 4 and the Z-axis adjustment handle 5, the positions in the X, Y, and Z directions can be finely adjusted respectively. By adjusting the positions of the three axes, the main shaft of the drive sensor 8 and the main shaft of the coupling 9 of the detection platform can be aligned coaxially, and optimal position coupling can be achieved in the Z-axis direction. At the same time, the driver 8 of the elastic calibrator is installed on the top of the three-axis fine-tuning platform 7 to realize the overall transmission operation process. Then, by connecting the calibrator and the detection head of the sampled device in series, the main shaft of the coupling 9 of the tested device 11 is passively rotated by changing the angle output of the calibrator. The rotation angle linearly and stably increases from 0° to 4°45′. Within each scale increment, the elasticity calibrator drives sensor 8 to sample and detect torque, thus obtaining the linear correspondence between the angle and torque graph of the scanned thromboelastography head sensor. The elasticity calibrator continuously outputs several standard values, each corresponding to a measured value at that angle. Through multi-point observation, a linear compensation function is established to achieve linear calibration of the calibrated device. Furthermore, following certain rules, the main shaft of the rotating simulation device is rotated in an orderly manner according to a predetermined angle and torque to simulate the coagulation process of some special specimens. In this case, the elasticity calibrator acts as a torque function generator, enabling the solution to achieve multiple torque outputs, realize linear calibration of the elastography sensor, simulate various abnormal sample curves, and scan the elasticity curve of the reference device before comparative experiments. This significantly improves product quality and production efficiency in factories, greatly enhances R&D efficiency in scientific research, and, in clinical practice, not only improves equipment accuracy but also significantly reduces training costs, providing clinicians with a solid and reliable standard.

[0058] Please see Figure 1-2 The three support columns 13 are all made of a combination of stainless steel and rubber layers. The upper and lower ends of the support column 13 are made of stainless steel plates, and the middle end is fixedly connected with a rubber sleeve.

[0059] In use, this solution uses a combination of stainless steel and rubber surfaces to make the support column 13 more stable and provide a certain buffering effect during the placement of the device under test 11 and the support plate 14. At the same time, the stainless steel plate on its bottom surface can increase the friction between it and the support base plate 12, thereby preventing the device under test 11 and the support plate 14 from shifting during placement.

[0060] Please see Figure 1-2 Three support columns 13 are arranged at equal angles on the upper end of the support base plate 12, two of which are located on the lower side of the bearing plate 14 and are on the same horizontal plane, and the other support column 13 is located on the lower side of the device under test 11.

[0061] This solution places the support column 13 and the upper side of the support base plate 12 at equal angles. By fixing the tested device 11 and the bearing plate 14 to them, the tested device 11 and the bearing plate 14 can have high stability due to the triangular state. This makes the tested device 11 and the bearing plate 14 more stable when placed and less prone to shaking.

[0062] Please see Figure 2-4 The motor driving sensor 8 is a voice coil motor based on magnetic coded feedback.

[0063] In the process of using this solution, an elasticity calibrator driver 8 is installed on the top of the three-axis fine-tuning platform 7. The core of the driver 8 is a voice coil motor based on magnetic coding feedback, which makes the voice coil motor both the driver of the intelligent elasticity calibrator and the sensor of this device. For example, when a person stirs coffee, honey, and batter with their hand, the hand acts as the driver for the object being stirred. At the same time, the hand can also feel the different resistances encountered when stirring coffee, honey, and batter. From a perception perspective, the hand acts as the sensor.

[0064] Please see Figure 4 The connector 10 has an internal wire connector, which is electrically connected to a control circuit board via a wire harness. The control circuit board is electrically connected to host computer software at its external end.

[0065] During use, this solution involves setting up a control circuit board connected to the elasticity calibrator, which is controlled by a host computer software. This allows for the switching, driving, and output of various working modes of the elasticity calibrator.

[0066] Please see Figure 1 and 5The shock-absorbing base includes a first connecting plate 31 located at the lower end of the horizontal adjusting screw 2. The upper end of the first connecting plate 31 has multiple evenly distributed through holes 32. The first connecting plate 31 is fixedly connected to the horizontal adjusting screw 2 by bolts inserted between the inner walls of the through holes 32. A shock-absorbing pad 33 is fixedly connected to the lower side of the first connecting plate 31. A rubber support 34 is located on the lower side of the shock-absorbing pad 33. A damper 35 is installed between the inner walls of the shock-absorbing pad 33 and the rubber support 34. Multiple high-damping vibration-isolating rubber pads 36 are fixedly connected between the shock-absorbing pad 33 and the inner walls of the rubber support 34. The high-damping vibration-isolating rubber pads 36 are sleeved on the outside of the damper 35.

[0067] In this solution, by bolting 31 to the bottom of the leveling screw 2, multiple shock-absorbing bases support the base 1 and the leveling screw 2. When the base 1 vibrates during operation, its high-damping vibration-isolating rubber pad 36 dissipates or absorbs the energy generated by the vibration of the air compressor 1 under friction, bending (or shearing, torsion), and elasto-plastic (or viscoelastic) hysteretic deformation, thereby reducing the vibration response of the entire device and preventing damage or loosening of the structure due to vibration. This achieves the purpose of vibration control. Furthermore, with the reduction of vibration force, the noise generated during operation is also reduced accordingly, ensuring the working environment for the staff.

[0068] Please see Figure 5 The outer end of the high-damping vibration isolation rubber pad 36 is fixedly connected to a protective sleeve 37, which is made of rubber material.

[0069] When this solution is in use, because the protective sleeve 37 is made of rubber, when the high-damping vibration isolation rubber pad 36 is subjected to vibration force and undergoes mutual friction, bending (or shearing, torsion), or hysteretic deformation, the protective sleeve 37 deforms synchronously with the high-damping vibration isolation rubber pad 36 due to the deformation effect of the rubber material. At the same time, it also increases the frictional force between the protective sleeve 37 and the high-damping vibration isolation rubber pad 36. Under the increased frictional force, the effect on the vibration force is increased, expanding the energy dissipation or absorbing the energy generated during the overall vibration, thereby reducing the overall vibration response. Furthermore, with the protective sleeve 37 in place, the high-damping vibration isolation rubber pad 36 can be protected during daily use, avoiding corrosion from the outside air and extending the service life of the high-damping vibration isolation rubber pad 36.

[0070] Please see Figure 1-2 The thermostatic plate 17 is sleeved on the outside of the telescopic rod 16, and the lower end of the telescopic rod 16 is threaded with a limit nut, with the thermostatic plate 17 located on the upper side of the limit nut.

[0071] In the course of use, if the constant temperature plate 17 wears out and needs to be replaced, the staff can remove the limiting nut below it to replace the constant temperature plate 17, thereby greatly improving the efficiency of staff in maintaining and replacing the device components.

[0072] Please see Figure 1-2 The support base plate 12 is made of stainless steel, and the upper end of the support base plate 12 has multiple evenly distributed mounting holes.

[0073] This solution uses stainless steel to make the support base plate 12, which can prevent corrosion from the outside air during daily use and extend the service life of the support base plate 12. At the same time, the multiple mounting holes make it easy for workers to install it in different positions, improving the convenience of installation.

[0074] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
