Description

Technical Field

[0001] The present invention relates to the technical field of mass spectrometers, and in particular to a detection device and a detection method for blood medical testing. Background Art

[0002] Mass spectrometers can be used for blood testing and play an important role in many fields such as clinical diagnosis and drug development. When providing medical assistance, it is usually necessary to conduct timely testing of the patient's blood in different scenarios so that medical personnel can make timely judgments on the patient's medication situation. The mass spectrometer is an instrument that ionizes the sample and then separates and detects ions based on the mass-to-charge ratio of the ions. During the detection process, it is necessary to maintain a horizontal state to ensure the accuracy of the test results and the normal operation of the internal components of the instrument.

[0003] To this end, Chinese patent CN118501239B discloses a movable blood testing mass spectrometer, which can detect the tilt state of the blood testing mass spectrometer through a horizontal detection component, thereby controlling the extension of the first electric telescopic rod to ensure that the bottom plate can always be parallel to the ground during the movement, reducing the tilt of the blood testing mass spectrometer during the movement, preventing the blood testing mass spectrometer from tilting when detecting blood during the movement, causing the electron and ion flow paths inside the mass spectrometer to be adversely affected, causing the performance of the ion source or mass spectrometer detector components to decline, affecting the quality of the analysis results, and improving the accuracy and reliability of the blood testing mass spectrometer in testing patient blood during the movement.

[0004] However, the method of adjusting the horizontal state of the base plate by extending and retracting the electric telescopic rod has a lag. After the tilt state is detected by the detection component, the adjustment is performed. During the adjustment process, the base plate and the mass spectrometer will still tilt. In addition, during the adjustment process, if the extension speed of the electric telescopic rod is too fast, the electric telescopic rod will collide with the ground; if the extension speed of the electric telescopic rod is too slow, the tilt time of the mass spectrometer will be prolonged, which will have a significant impact on the accuracy of the detection results.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figure 1-Figure 4 : A detection device, comprising a base plate 1, a support plate 2, a mass spectrometer 3 and an auxiliary control mechanism 4; a rotating hinge seat 11 is rotatably arranged on the base plate 1, and at least three universal wheels 12 are arranged at the bottom of the base plate 1; a fixed hinge seat 21 and an electric push rod 22 are arranged on the support plate 2; the fixed hinge seat 21 is hinged with the rotating hinge seat 11; there are at least three electric push rods 22, and the plurality of electric push rods 22 are distributed in a circular array about the axis of the rotating hinge seat 11; the electric push rod 22 comprises a retractable piston rod 221, and a spherical abutment block 222 is arranged at one end of the piston rod 221 away from the support plate 2, and the spherical abutment block 222 abuts against the base plate 1 under the drive of the electric push rod 22; an electronic level 23 for detecting the horizontal state of the support plate 2 is arranged on the support plate 2; the mass spectrometer 3 is installed on the support plate 2; the auxiliary control mechanism 4 is used to connect the base plate 1 and the support plate 2.

[0035] The present invention realizes the function of quickly adjusting the horizontal state of the support plate 2 through the cooperation of the base plate 1, the support plate 2 and the auxiliary control mechanism 4, thereby achieving the effect of maintaining the mass spectrometer 3 in a horizontal state. When the mass spectrometer 3 moves, the electric push rod 22 accurately adjusts the height of the support plate 2 and the horizontal state of the support plate 2 by adjusting the extension and contraction of the piston rod 221. When the universal wheels 12 of the base plate 1 contact the ground and support the base plate 1, the support plate 2 can still be stably supported. The base plate 1 and the support plate 2 are connected by the fixed hinge seat 21 and the rotating hinge seat 11 to keep the spacing between the middle parts of the two consistent, and then the base plate 1 and the support plate 2 can be auxiliaryly connected through the connection of the auxiliary control mechanism 4. During the movement process, when encountering a raised or sunken part of the road surface, it can respond quickly to support the support plate 2, greatly reduce the shaking amplitude of the support plate 2 and the mass spectrometer 3 located on the support plate 2, and improve the working stability of the mass spectrometer 3. The support plate 2 is provided with a controller for human-machine interaction, and the electric push rod 22 and the electronic level 23 are electrically connected to the controller. The electronic level 23 is provided with a capacitive sensor inside, which uses the principle that the capacitance value changes with the distance between the plates. When the instrument is tilted, the distance between the capacitor plates inside the sensor changes, thereby measuring the tilt angle. The auxiliary control mechanism 4 connects the bottom plate 1 and the support plate 2 on the side of the fixed hinge seat 21.

[0036] In the working state, when the operator moves the mass spectrometer 3, as the ground rises and falls, the base plate 1 abuts against the ground through the universal wheels 12 under the action of gravity, so that the base plate 1 can always be close to the ground, and then the rotating hinge seat 11 and the fixed hinge seat 21 provide sufficient support force for the center position of the support plate 2. When the ground rises and falls greatly, the auxiliary control mechanism 4 is connected to apply a pre-tightening force to the base plate 1 and the support plate 2, and then the horizontal state of the support plate 2 is initially maintained. In this process, the controller sends a signal to the electric push rod 22, and the support plate 2 is supported for a long time through the cooperation of multiple electric push rods 22. In this way, the mass spectrometer 3 and the support plate 2 are prevented from shaking greatly during the movement, and the working stability and detection accuracy of the mass spectrometer 3 are improved.

[0037] Reference Figure 1 , Figure 3 and Figure 4 : The auxiliary control mechanism 4 includes a sensing component 41 and a connecting component 42; the sensing component 41 and the connecting component 42 are each provided with at least three groups, and the sensing components 41 and the connecting components 42 correspond one to one, and the multiple groups of sensing components 41 and the connecting components 42 are distributed in a circular array along the axis of the rotating hinge seat 11; the sensing component 41 is used to sense the horizontal state of the base plate 1; the connecting component 42 is used to connect the base plate 1 and the support plate 2; in the working state, when the sensing component 41 senses that the base plate 1 is in a tilted state, the sensing component 41 pulls or pushes the connecting component 42.

[0038] The present invention realizes the function of sensing the horizontal state of the bottom plate 1 through the sensing component 41, and cooperates with the connecting component 42 to adjust the tension provided by the connecting component 42 according to the inclination of the bottom plate 1, thereby maintaining the stability of the support plate 2 when the bottom plate 1 shakes, and improving the working stability of the mass spectrometer 3. In order to improve the detection accuracy of the horizontal state of the bottom plate 1, multiple groups of sensing components 41 and connecting components 42 are set. In this embodiment, the sensing components 41 and connecting components 42 are each provided with four groups. Since the sensing component 41 will be close to the side plate of the bottom plate 1, when the bottom plate 1 tilts, the rotation amplitude of the edge position of the bottom plate 1 is larger than that of the middle position, which can effectively improve the detection sensitivity of the sensing component 41, thereby further accelerating the response rate of the device. The connecting component 42 is provided with multiple groups, and through the multiple groups of connecting components 42, the sensing components 41 at each position are cooperated. When the sensing component 41 on the corresponding side senses the inclination of the bottom plate 1, the connecting component 42 on the corresponding side provides tension or support force, and timely provides support force to the support plate 2, thereby maintaining the horizontal state of the support plate 2.

[0039] Reference Figure 3-Figure 5 : The sensing component 41 includes a mounting seat 411 and a counterweight 412; the mounting seat 411 is installed on the base plate 1; the counterweight 412 is slidably installed on the mounting seat 411; first elastic members 413 for controlling the resetting of the counterweight 412 are arranged on both sides of the counterweight 412; the two ends of the connecting component 42 are respectively connected to the counterweight 412 and the support plate 2; in the working state, when the base plate 1 is in an inclined state, the counterweight 412 moves under the action of gravity, and the two first elastic members 413 on both sides of the counterweight 412 contract and extend respectively, and the counterweight 412 pulls or pushes the connecting component 42.

[0040] The present invention realizes the function of sensing the connection state of the base plate 1 through the mounting seat 411, the counterweight 412 and the connecting assembly 42. When the mass spectrometer 3 is moved, as the ground rises and falls, the base plate 1 tilts along with the ground under the action of gravity. The mounting seat 411 on the base plate 1 tilts accordingly with the inclination of the base plate 1, the counterweight 412 slides in the mounting seat 411 under the action of gravity, and the first elastic member 413 on both sides of the counterweight 412 stretches or contracts under the pulling and pushing action of the counterweight 412. When the counterweight 412 moves, it pulls or pushes the support plate 2 through the connecting assembly 42, provides pulling force or pushing force on the corresponding side of the support plate 2, provides supporting force to the support plate 2, and maintains the horizontal state of the support plate 2.

[0041] Reference Figure 3-Figure 5: A guide rod 4121 is provided on the counterweight block 412, and a guide groove 4111 is opened on the mounting seat 411, and the guide rod 4121 of the counterweight block 412 slides with the guide groove 4111; two damping rods 414 are provided in the mounting seat 411, and the two damping rods 414 are respectively located at the two ends of the counterweight block 412, and a pressure sensor is built into the counterweight block 412, and the two ends of the first elastic member 413 are respectively connected to the two ends of the damping rod 414, and the two ends of the damping rod 414 are respectively connected to the mounting seat 411 and the counterweight block 412, and one of the damping rods 414 is connected to the pressure sensor on the counterweight block 412.

[0042] The present invention realizes the function of guiding the movement of the counterweight 412 through the guide groove 4111, the guide rod 4121 and the damping rod 414. In order to standardize the moving direction of the counterweight 412, the guide groove 4111 and the guide rod 4121 are provided. When the base plate 1 is tilted, the counterweight 412 will slide along the mounting seat 411 under the action of gravity. In order to prevent the counterweight 412 from pulling the first elastic member 413 and causing deflection during the movement, the guide groove 4111 is provided on the mounting seat 411, and the guide rod 4121 on the counterweight 412 is used to guide and restrict the mounting seat 411, so as to ensure that the counterweight 412 can be stably installed in the mounting seat 411. By setting the damping rod 414, the moving direction of the counterweight 412 can be further stabilized. When the counterweight 412 slides with gravity, the damping provided by the damping rod 414 can prevent the counterweight 412 from reciprocating with the expansion and contraction of the first elastic member 413 , thereby improving the working stability of the sensing component 41 .

[0043] Reference Figure 5-Figure 8 : The connecting component 42 includes a main rod 421, a secondary rod 422 and a movable hinge seat 423; the main rod 421 is hinged with the movable hinge seat 423; the secondary rod 422 is slidably matched with the main rod 421, and a second elastic member 4221 is provided on the secondary rod 422, and the two ends of the second elastic member 4221 are respectively connected to the main rod 421 and the secondary rod 422; the movable hinge seat 423 is rotatably set on the counterweight block 412; in the working state, when the base plate 1 is in a horizontal state, the secondary rod 422 is in a contracted state under the elastic force of the second elastic member 4221, and multiple secondary rods 422 all apply a pulling force to the support plate 2.

[0044] The present invention realizes the function of connecting the bottom plate 1 and the support plate 2 through the main rod 421, the auxiliary rod 422 and the movable hinge seat 423, and provides a stable pulling force in four directions of the support plate 2 through the pulling force of the second elastic member 4221. When the counterweight 412 moves under the action of gravity, the main rod 421 is pulled or pushed through the movable hinge seat 423, and the main rod 421 transmits the force to the auxiliary rod 422 through the second elastic member 4221, and pushes or pulls the support plate 2 through the auxiliary rod 422, providing a pulling force or a pushing force on the corresponding side of the support plate 2, providing a supporting force to the support plate 2, and maintaining the horizontal state of the support plate 2. The active hinge connection between the movable hinge seat 423 and the main rod 421 improves the flexibility of the main rod 421 and the auxiliary rod 422. When the bottom plate 1 tilts in any direction, the movable hinge seat 423 can rotate relative to the counterweight 412. Then, through the rotation connection between the main rod 421 and the movable hinge seat 423, the main rod 421 and the auxiliary rod 422 can be tilted in the corresponding direction, and the connection between the counterweight 412 and the support plate 2 can be maintained. By providing tension in four directions, the force balance of the support plate 2 is maintained, and when the counterweight 412 moves, the balance is broken. Through the tension of different sizes provided in each direction, the support plate 2 can have a rotation tendency, and through the tilting of the bottom plate 1, the support plate 2 is supported to prevent the support plate 2 from tilting with the shaking of the bottom plate 1.

[0045] Reference Figure 5-Figure 8 : A connecting shaft 4222 is provided at one end of the auxiliary rod 422 away from the main rod 421; a fixing seat 424 is provided on the support plate 2, and a fixing shaft 4241 is provided on the fixing seat 424; a connecting rod 425 is provided on the fixing seat 424, and both ends of the connecting rod 425 are hinged to the fixing shaft 4241 and the connecting shaft 4222 respectively.

[0046] The present invention realizes the function of connecting the secondary rod 422 and the support plate 2 through the connecting shaft 4222, the fixing seat 424 and the connecting rod 425. Through the setting of the connecting shaft 4222 and the connecting rod 425, when the counterweight 412 moves in the direction close to the rotating hinge seat 11, the connecting rod 425 is pushed to deflect in the direction close to the rotating hinge seat 11, thereby reducing the distance between the counterweight 412 and the support plate 2. When the counterweight 412 moves in the direction away from the rotating hinge seat 11, the connecting rod 425 is pulled by the main rod 421, the secondary rod 422 and the second elastic member 4221, so that the connecting rod 425 is deflected in the direction away from the rotating hinge seat 11, thereby increasing the distance between the counterweight 412 and the support plate 2. When the bottom plate 1 tilts to one side, the two counterweights 412 along the tilting direction will slide toward the same side under the action of gravity, and one of the two counterweights 412 moves in the direction close to the rotating hinge seat 11, and the other moves in the direction away from the rotating hinge seat 11. Then, through the deflection of the two connecting rods 425, the spacing between the corresponding sides of the support plate 2 and the bottom plate 1 is preliminarily adjusted, and the support plate 2 is preliminarily supported in a short time. In this process, once the counterweight block 412 moves, the pressure sensor set on the counterweight block 412 senses the pressure change and feeds back the signal to the controller, which first controls the electric push rods 22 to shrink synchronously. Then, the horizontal state of the bottom plate 1 and the support plate 2 is analyzed through the electronic level 23 and the signals fed back by multiple pressure sensors, and then the extension and retraction of each electric push rod 22 is adjusted. The electric push rod 22 is adjusted to provide stable support, so that the mass spectrometer 3 can move on the ground with different undulations in the working state.

[0047] Reference Figure 6 and Figure 7 : The connecting rod 425 is slidably matched with the connecting shaft 4222, and a limit block 4223 is provided at both ends of the connecting shaft 4222 for limiting the sliding range of the connecting rod 425; in the working state, when the movable hinge seat 423 is in an inclined state relative to the mounting seat 411, the connecting rod 425 slides along the axial direction of the connecting shaft 4222.

[0048] The present invention realizes the function of limiting the deviation direction of the connecting rod 425 through the limit blocks 4223 at both ends of the connecting shaft 4222. In the working state, when the base plate 1 is tilted, the movable hinge seat 423 on the corresponding side will rotate relative to the counterweight block 412, and then drive the main rod 421, the auxiliary rod 422 and the connecting shaft 4222 to rotate through the movable hinge seat 423. When the connecting shaft 4222 rotates, the two connecting rods 425 will slide along the axial direction of the connecting shaft 4222. In order to prevent the connecting rod 425 from separating from the connecting shaft 4222, the limit blocks 4223 are set at both ends of the connecting shaft 4222, which not only improves the matching stability between the components, but also prevents the excessive tilting between the base plate 1 and the support plate 2.

[0049] Reference Figure 1 , Figure 2 and Fig. 9 : A limiting plate 24 for supporting the mass spectrometer 3 is provided on the support plate 2; two extension rods 241 are provided on the limiting plate 24, a cross bar 242 is provided on the extension rod 241, and the two extension rods 241 are connected by the cross bar 242.

[0050] The present invention realizes the function of facilitating the operator to pull or push the mass spectrometer 3 to move by means of the limit plate 24, the extension rod 241 and the cross bar 242. The cross bar 242 is a cylindrical straight rod, and its shape is convenient for the operator to grasp. When moving the mass spectrometer 3, the operator first holds the cross bar 242, and then pulls or pushes the cross bar 242, thereby applying a thrust or a pull to the support plate 2, and finally realizes the rapid movement of the base plate 1, the support plate 2 and the mass spectrometer 3 through the universal wheel 12 at the bottom of the base plate 1.

[0051] Reference Figure 3 and Fig.10 An arc groove 13 for abutting against the spherical abutment block 222 is provided on the bottom plate 1, and a wear-resistant coating is provided on the groove wall of the arc groove 13.

[0052] The present invention realizes the function of cooperating with the spherical abutment block 222 through the arc groove 13. The material of the wear-resistant coating is preferably epoxy resin. In the working state, when the electric push rod 22 drives the piston rod 221 to extend, the spherical abutment block 222 at the end of the piston rod 221 abuts against the arc groove 13. The coating is provided to improve the wear resistance of the groove wall of the arc groove 13, and when the coating is severely scratched or damaged, it can be quickly repaired to maintain the working stability of the equipment.
