Description

Technical Field

[0002] PCT, or procalcitonin, is a protein. Its level in plasma increases when there are severe bacterial, fungal, parasitic infections, sepsis, and multiple organ failure. Open heart surgery is a surgical operation in which the heart is opened with or without stopping to correct defects or remove lesions, install valves, and bypass blood vessels in order to restore the anatomical appearance and physiological function of the heart. Serum is collected on days 0, 1, 2, and 3 after the operation to measure PCT values. The data obtained are statistically analyzed, summarized, and concluded to prove that procalcitonin can serve as a good indicator of the prognosis of patients undergoing open heart surgery, which is of great significance for the foreseeability and early treatment of complications.

[0024] The PCT content detection device for postoperative monitoring and evaluation of open heart surgery provided by the present invention is now described.

[0025] like Figures 1 to 3 As shown, one embodiment of the present invention provides a PCT content detection device for postoperative monitoring and evaluation of open heart surgery, including a shell 1 with an upper opening and a placement plate 2 suspended in the shell 1, wherein the placement plate 2 is provided with multiple rows of placement holes 21 for reagent bottles to be inserted, and the placement plate 2 is provided with a clamping mechanism 3 for clamping and fixing the reagent bottles in all the placement holes 21 at the same time; when the placement plate 2 is in an initial state, the bottom of the reagent bottle contacts the inner bottom wall of the shell 1; sliding frames 4 are provided on the left and right sides of the placement plate 2, and a driving mechanism 5 is provided in the shell 1, and the driving mechanism 5 is used to first drive the clamping mechanism 3 to clamp and fix all the reagent bottles, and then drive the placement plate 2 to rise through the two sliding frames 4, at which time the placement plate 2 is slidably arranged between the two sliding frames 4 back and forth; a shaking mechanism 6 is also provided in the shell 1 for driving the placement plate 2 to slide back and forth after it is raised.

[0026] Compared with the prior art, the PCT content detection device for postoperative monitoring and evaluation of open heart surgery provided in the present embodiment can place multiple reagent bottles into the placement hole 21, and the clamping mechanism 3 is used to clamp and fix all the reagent bottles through the driving mechanism 5, and then the placement plate 2 is driven to rise through the two sliding frames 4, so that the bottom of the reagent bottle is suspended in the air, which is convenient for the subsequent shaking mechanism 6 to shake it back and forth; by first conveniently placing all the reagent bottles, and then uniformly fixing all the reagent bottles, and then driving all the reagent bottles to be suspended in the air and shaken, after the shaking is completed, the placement plate 2 is lowered to make the reagent bottles contact the inner bottom wall of the shell 1 again, and the clamping mechanism 3 releases the reagent bottles and they can all be taken out. Under the premise of ensuring the safety of the reagent bottles, the overall efficiency of PCT content detection is improved.

[0027] like Figures 4 to 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The clamping mechanism 3 includes an arc-shaped clamping plate 31, an extrusion block 32, an extrusion rod 33 and a reset assembly 34; clamping grooves 22 are provided on both sides of the placement hole 21, and each two arc-shaped clamping plates 31 slide relatively in the corresponding clamping grooves 22; the extrusion blocks 32 are correspondingly fixed on the back of each arc-shaped clamping plate 31; a plurality of extrusion grooves 23 connected to each of the clamping grooves 22 are provided in the placement plate 2, and each of the extrusion rods 33 slides in the extrusion grooves 23; the extrusion rods 33 are provided with a position toward each of the extrusion blocks 32 The inclined groove 331, when the extrusion block 32 is in the initial state, one end is located in the corresponding inclined groove 331, and the inclined groove 331 has an inclined surface for extruding the extrusion block 32; all the extrusion rods 33 are fixedly connected, and the driving mechanism 5 is used to drive all the extrusion rods 33 to slide, and the inclined surface in the inclined groove 331 extrude the extrusion block 32 in the direction away from the inclined groove 331; multiple groups of reset components 34 are arranged in the placement plate 2, and the reset components 34 are used to drive the extrusion block 32 and the extrusion rod 33 to reset to the initial state.

[0028] Furthermore, an elastic cushion may be provided on the inner curved surface of the arc-shaped clamping plate 31 .

[0029] Before the driving mechanism 5 drives the extrusion rod 33 to slide, the arc-shaped clamping plates 31 are all located in their respective extrusion grooves 23; after the reagent bottles are placed, the driving mechanism 5 drives all the extrusion rods 33 to slide synchronously. At this time, the inclined surface in each inclined groove 331 squeezes the extrusion block 32 outward, so that the extrusion block 32 drives the arc-shaped clamping plate 31 to clamp and fix the reagent bottles, thereby improving the efficiency of fixing all reagent bottles at the same time.

[0030] like Figures 4 to 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The reset assembly 34 includes a reset spring 341 and a reset block 342. A reset groove 24 is opened on one side of the extrusion groove 23. The reset spring 341 is arranged in the corresponding reset groove 24. The reset block 342 is slidably arranged in the reset groove 24 and connected to the reset spring 341. One side of the reset block 342 is fixed to the extrusion rod 33; the reset spring 341 is also arranged in the clamping groove 22 and connected to the back side of the arc clamping plate 31; when the extrusion block 32 and the extrusion rod 33 are in the initial state, the reset spring 341 is in a natural state.

[0031] When the driving mechanism 5 drives the extrusion rod 33 to slide, the extrusion rod 33 and the arc-shaped clamping plate 31 drive the corresponding reset block 342 to slide, causing the reset spring 341 to be compressed; after the extrusion rod 33 is not subjected to thrust, the rebound force of each reset spring 341 drives the extrusion rod 33 and the arc-shaped clamping plate 31 to reset, so as to clamp and fix the reagent bottle next time.

[0032] like Figure 3 and Figure 6 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The driving mechanism 5 includes a driving screw 51, a driving motor 52, a driven shaft 53, a driving gear 54, a driven gear 55 and a pushing assembly 56; the driving screw 51 is rotatably connected in the shell 1 and is parallel to the sliding direction of the extrusion rod 33, and the driving motor 52 is arranged in the shell 1 and drives the driving screw 51 to rotate; the driven shaft 53 is rotatably connected between the placement plate 2 and the driving screw 51, the driving gear 54 is coaxially fixed on the driving screw 51, and the driven gear 55 is coaxially fixed on the driven shaft 53 and meshes with the driving gear 54; the pushing assembly 56 is arranged between the driven shaft 53 and the extrusion rod 33, and the pushing assembly 56 is used to push the extrusion rod 33 to slide until the reagent bottle is clamped and fixed.

[0033] like Figure 7 and Figure 8As shown, the push assembly 56 includes a push screw 561, a guide frame 562, a push spring 563 and a force plate 564; a threaded hole 531 is coaxially provided at the end of the driven shaft 53, and one end of the push screw 561 is threadedly connected in the threaded hole 531; the guide frame 562 is fixed in the housing 1, and the push screw 561 passes through the guide frame 562, and a guide block is fixed in the guide frame 562, and a guide groove for the guide block to slide in the outer circumference of the push screw 561 is provided along its length direction; the push spring 563 is arranged in the threaded hole 531 and connected to the push spring 563; the top of the force plate 564 is fixed to the extrusion rod 33, and the bottom surface of the placement plate 2 is provided with a guide groove for the force plate 564 to slide in the outer circumference of the push screw 561; 4 passes through the strip hole; the pushing screw 561 and the threaded hole 531 are only partially threaded; the outer end of the pushing screw 561 pushes the force-bearing plate 564 to slide until the reagent bottle is clamped, and the threads of the pushing screw 561 and the threaded hole 531 are separated, and the pushing spring 563 is in a stretched state; when the pushing screw 561 moves into the inside of the threaded hole 531 until the threads are separated, the pushing spring 563 is in a compressed state; a self-locking component 7 is provided between the force-bearing plate 564 and the placement plate 2, and the self-locking component 7 is used to fix the position of the force-bearing plate 564 after the pushing screw 561 has pushed the force-bearing plate 564, and to release the fixation of the force-bearing plate 564 after the placement plate 2 is lowered and reset.

[0034] The threads in the threaded hole 531 are only provided at a position close to the outlet thereof. Figure 7 The push screw 561 is in a state after it moves outwards to be separated from the inner thread of the threaded hole 531 . At this time, the driven shaft 53 is idle, and the push screw 561 will not move outwards of the threaded hole 531 any more. Figure 8 The push screw 561 moves inwards until it is separated from the inner thread of the threaded hole 531 again. At this time, the driven shaft 53 is also idling, and the push screw will not move toward the inside of the threaded hole 531 any more.

[0035] After all reagent bottles are placed, the driving motor 52 is started to rotate the driving screw 51, and the driving screw 51 drives the driven gear 55 and the driven shaft 53 to rotate through the driving gear 54. Due to the guiding limit of the guide frame 562 on the pushing screw 561, the rotation of the driven shaft 53 causes the pushing screw 561 to move outward. At this time, the placement plate 2 has not yet begun to rise, and the outer end of the pushing screw 561 pushes the bottom of the force plate 564. The force plate 564 drives the extrusion rod 33 to slide so that all reagent bottles are clamped and fixed. At this time, the pushing screw 561 and the threaded hole 531 of the driven shaft 53 have been threadedly separated. The driving motor 52 does not need to be stopped, and the driven shaft 53 is in an idling state. Until the two sliding frames 4 drive the placement plate 2 to rise, the driving motor 52 stops, and the placement plate 2 can be reciprocated and shaken by the shaking mechanism 6.

[0036] After the reagent bottle is shaken, the driving motor 52 drives the driving screw 51 to reverse. At this time, the pushing spring 563 in the stretched state applies a pulling force toward the inside of the threaded hole 531 to the pushing screw 561, so that the pushing screw 561 cooperates with the thread in the threaded hole 531 again, until the pushing screw 561 moves toward the inside of the threaded hole 531 until the threads of the two are separated again. At this time, the pushing spring 563 is in a compressed state, and the driven shaft 53 idles again; at the same time, the two sliding frames 4 drive the placement plate 2 to descend and reset to the initial state, the self-locking component 7 releases the fixation of the force-bearing plate 564, and the multiple reset components 34 simultaneously drive the extrusion rod 33 and the extrusion block 32 to reset. After all reagent bottles are released, they can be taken out, which improves the convenience of the entire operation process and the safety of the reagent bottle detection process.

[0037] like Figures 7 and 8 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The outer end of the push spring 563 is connected to the inner end of the push screw 561 through a hook and a hanging ring, and the guide groove on the push screw 561 is set through both ends. When the placement plate 2 is in the initial state, the two sliding frames 4 are separated from the placement plate 2, and the placement plate 2 can be directly taken out from the housing 1.

[0038] When it is necessary to shake another batch of reagent bottles, first take out the placement plate 2 from the shell 1, and then start the drive motor 52 to make the driven shaft 53 drive the push screw 561 to separate from the thread in the threaded hole 531. At this time, the push screw 561 can be pulled outward and separated from the push spring 563, and the push screw 561 with the corresponding thread length is replaced according to the diameter of the reagent bottle. The longer the thread on the push screw 561, the longer the moving distance of the push screw 561 driven by the driven shaft 53, and the more suitable it is for small-diameter reagent bottles. Conversely, it is suitable for large-diameter reagent bottles. Reagent bottles of different diameters can be clamped and fixed, thereby improving the applicability of the device.

[0039] like Figures 9 and 10 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The self-locking component 7 includes a mounting frame 71, a micro-electric cylinder 72, a connecting plate 73, a pawl 74 and a ratchet 75; the mounting frame 71 is fixed to the bottom surface of the placement plate 2, the micro-electric cylinder 72 is arranged on the mounting frame 71, the connecting plate 73 is fixed on the telescopic rod of the micro-electric cylinder 72, the pawl 74 is arranged on the connecting plate 73, and the ratchet 75 is fixed on the force plate 564 and meshes with the pawl 74; the telescopic direction of the micro-electric cylinder 72 is parallel to the rotation axis of the pawl 74.

[0040] When the pushing screw 561 pushes the force plate 564 to move, the ratchet 75 moves on the pawl 74, and the pawl 74 always has a one-way limiting effect on the ratchet 75 and the force plate 564, thereby improving the stability of the reagent bottle after being clamped and fixed; when the reagent bottle needs to be loosened, the micro-electric cylinder 72 is started to drive the pawl 74 to descend, so that the pawl 74 is separated from the ratchet 75. At this time, the multiple reset components 34 drive the extrusion rod 33 to reset while driving the force plate 564 and the ratchet 75 to reset. The micro-electric cylinder 72 drives the pawl 74 upward to engage with the ratchet 75 again, thereby improving the convenience of self-locking and unlocking the force plate 564.

[0041] like Figures 2 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The driving mechanism 5 also includes two movable plates 57. The driving screw 51 is divided into two sections of threads with opposite rotation directions by its middle part. The two movable plates 57 are respectively threadedly connected to the threads with different rotation directions, and the top of the movable plate 57 is fixed to the corresponding sliding frame 4; the bottom of the sliding frame 4 facing the side of the placement plate 2 is an inclined surface, and this inclined surface is used to squeeze the placement plate 2 to make it rise.

[0042] When the driving motor 52 starts to drive the driving screw 51 to rotate, the two movable plates 57 approach each other, and the movable plate 57 drives the sliding frame 4 to move toward the placement plate 2. The inclined surfaces of the two sliding frames 4 simultaneously squeeze the bottom edge of the placement plate 2, causing the placement plate 2 to rise along the inclined surface, so that the bottom of the reagent bottle is suspended in the air, thereby improving the lifting efficiency of the placement plate 2.

[0043] like Figure 1 and Fig.11 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The shaking mechanism 6 includes a vertical motor 61, a cam 62 and a shaking assembly 63. The vertical motor 61 is arranged in the shell 1, and the cam 62 is fixed on the output shaft of the vertical motor 61. The cam 62 is used to push the placement plate 2 in a certain direction forward or backward after the rising is completed; the shaking assembly 63 is arranged between the placement plate 2 and the inner wall of the shell 1, and the shaking assembly 63 is used to drive the placement plate 2 to reset after the cam 62 completes the pushing.

[0044] After the driving mechanism 5 drives the placement plate 2 to rise, the vertical motor 61 is started to make the cam 62 and the shaking assembly 63 cooperate to achieve the reciprocating shaking of the placement plate 2, so that all reagent bottles are shaken horizontally to mix evenly.

[0045] like Fig.11 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The shaking assembly 63 includes a shaking spring 631 and a bonding plate 632. A plurality of shaking springs 631 are arranged on the inner wall of the shell 1. The bonding plate 632 is fixed to the outer end of the shaking spring 631, and the bonding plate 632 is tightly attached to the side wall of the placement plate 2.
