Description

Technical Field

[0001] The present application relates to the technical field of mass spectrometer stability detection, and in particular to a detection device for the stability of key performances of a clinical mass spectrometer. Background Art

[0002] The stability test of mass spectrometer is a key task in evaluating the performance of mass spectrometer. It mainly tests the ability of various key indicators of mass spectrometer to maintain a stable state during long-term operation. From the perspective of mass analysis, this includes the stability of mass-to-charge ratio (m / z), because the mass spectrometer ionizes the sample and separates and detects according to the mass-to-charge ratio of the ions. The stability of the mass-to-charge ratio is directly related to the accuracy of the test results. For example, when analyzing the molecular weight distribution of complex organic compounds, if the mass-to-charge ratio fluctuates, it will lead to deviations in the detected molecular mass. In terms of signal intensity, stability testing is also crucial. The signal intensity detected by the mass spectrometer reflects the number or concentration of ions in the sample. Stable signal intensity can ensure the reliability of data during quantitative analysis. If the signal intensity is unstable, the test results of the same sample at different times will vary greatly, affecting the accurate judgment of the sample component content. In addition, the resolution stability of the instrument is also part of the detection. High resolution allows the mass spectrometer to distinguish ions of different mass-to-charge ratios more accurately. Poor stability will cause the mass spectrum peak to become wider or deformed, resulting in a decrease in the ability to distinguish ions of adjacent mass-to-charge ratios. This will seriously affect the detection quality, especially when analyzing isotopes or complex mixtures. Through stability testing, the performance changes of the mass spectrometer can be discovered in time, ensuring that it can provide accurate and reliable detection data in many fields such as scientific research, environmental monitoring, and drug development. At present, the stability detection of mass spectrometers usually requires the use of special detection devices to assist in the detection. For example, the Chinese patent with the announcement number "CN217820643U" discloses a portable mass spectrometer performance test device, which includes a control device; a power adapter, which is used to power the control device; supporting wires, which are used to connect with various interfaces of the mass spectrometer; a simulated vacuum gauge, which is used to test the vacuum degree of the mass spectrometer; a suitcase, in which the control device, the power adapter, the supporting wires and the simulated vacuum gauge are all arranged; the power adapter, the supporting wires and the simulated vacuum gauge are all connected to the control device, and the control device includes a power conversion device, a communication device, a circuit device for detecting the voltage and resistance of the electric control device, an output control part for detecting and controlling the operation of the mechanical equipment of the mass spectrometer, and a display device, and the display device is used to display the detection data of the mass spectrometer and perform touch screen control. This device can reduce the difficulty of daily maintenance and troubleshooting of the electronic and mechanical components of the mass spectrometer; The above-mentioned device integrates the entire detection equipment inside a box, and does achieve the function of being easy to carry during use. However, in the specific use process, it still has obvious defects and shortcomings. First of all, since the design purpose of the device is to achieve portability, it needs to be moved and carried frequently. However, during the carrying process, shaking, impact and collision are inevitable. The device as a whole is composed of precision components, which are very sensitive to vibration. During the carrying process, if there is no corresponding buffering protection structure, it is easy to be damaged by vibration. Obviously, the current device does not add any protection measures in terms of buffering protection. As a result, if the device is carried frequently, it is very likely to be damaged or the detection will not work. In summary, the device has certain defects in the overall design and needs to be improved to improve its stability and reliability during carrying. Summary of the invention

[0024] The implementation principle of the detection device for the stability of key performance of a clinical mass spectrometer in the embodiment of the present application is as follows: by setting the height adjustment mechanism 3, during the use of the device, when the drive motor 323 is started, the drive motor 323 can drive the drive gear 324 to rotate. Since the drive gear 324 is meshed and connected with the transmission gear 322, the rotation of the drive gear 324 will assist the rotation of the transmission gear 322. When the transmission gear 322 rotates, it will synchronously drive the screw rod 33 located inside the slide groove 31 to rotate. The screw rod 33 rotates in the slide groove 31, and then synchronously drives the sliders 34 at both ends of the slide groove 31 to slide. It is worth noting that the threads at the two ends of the screw rod 33 rotate in opposite directions. As the screw rod 33 drives the slider 34 to slide, it will synchronously squeeze The linkage rod 36 is driven to assist in pushing the entire frame 61 upward. If the drive motor 323 is adjusted to reversely drive the transmission gear 322 to rotate, the linkage rod 36 can be adjusted to pull the frame 61 downward.

By providing the buffer mechanism 6, the case cover 2 can cover the top of the case body 1 during use of the device, and then the case body 1 can be locked by the buckle 9. During use, the case body 1 is lifted and carried by pulling the buckle groove on the top of the case cover 2. When the case body 1 is being carried, a side buffer assembly 63 is installed on each surface inside the groove body 62 on the frame body 61. During the carrying process, if an impact is encountered, the side buffer springs 634 on each surface in the groove body 62 can assist in buffering and shock resistance. When the device body 4 is impacted and moves toward one side, the side buffer spring 634 on the moving side will be squeezed, thereby assisting in preliminary buffering, and the side buffer spring 634 on the other side will be stretched to play a further buffering role. In this way, no matter which direction the device body 4 is impacted, it can assist in better buffering. Impact protection function. During its use, when there is an impact in the longitudinal direction, the corresponding inner hinge ball 636 and the outer hinge ball 633 will assist in the linkage rotation, so that the overall buffering pressure of the side buffer spring can also act on the device body 4, so that the whole has a strong buffering protection performance. In the process of longitudinal buffering, the main buffer spring 72 located at the bottom can assist in longitudinal buffering and shock absorption, and further improve the longitudinal buffering performance.
