[0032] Embodiment: An ultrasound left heart angiography examination device, see Figure 1-Figure 5 As shown, an ultrasonic probe 1 is included; the ultrasonic probe 1 generates an image of the internal structure of the human body by transmitting and receiving ultrasonic waves; It also includes a liquid storage tank 2, a piston 3, a handle 4, a magnetic ring I5, a magnetic ring II6, a discharge pipe 8, a discharge frame 9, a soft board 901, a smear frame 11, a connecting block 12, a rubber rod 13, a vibrator 14, a moving mechanism and a guiding mechanism; the right side of the ultrasonic probe 1 is connected to a liquid storage tank 2, and the liquid storage tank 2 is used to store coupling agent; a piston 3 is slidably arranged in the liquid storage tank 2; a handle 4 with a U-shaped structure is connected to the top of the piston 3; a magnetic ring I5 is connected to the side wall of the piston 3; a magnetic ring II6 is slidably arranged on the outer wall of the liquid storage tank 2; a moving mechanism is arranged on the liquid storage tank 2, and the moving mechanism is used to drive The magnetic ring II 6 slides on the outer wall of the liquid storage tank 2, and the magnetic ring II 6 drives the magnetic ring I 5 and the piston 3 to move synchronously through magnetic attraction and squeeze the coupling agent in the liquid storage tank 2, so as to realize automatic discharge of the coupling agent in the liquid storage tank 2; the bottom of the liquid storage tank 2 is connected with a discharge pipe 8; the bottom of the liquid storage tank 2 is connected with a discharge frame 9 connected with the discharge pipe 8, so that the coupling agent in the liquid storage tank 2 can fall into the discharge frame 9 through the discharge pipe 8 when discharging; the discharge frame 9 is connected with a soft board 901 for accumulating coupling agent, so that the coupling agent can be accumulated in the discharge frame 9, and the coupling agent in the discharge frame 9 is discharged. After a certain amount of coupling agent is accumulated, the coupling agent will gradually exert pressure to squeeze the soft board 901 until it is deformed and opened, so that the coupling agent in the discharge frame 9 can fall down evenly, thereby preventing the coupling agent in the discharge frame 9 from falling down from a single position; a guide mechanism is provided on the discharge frame 9, and a smear frame 11 for smoothing the coupling agent is connected to the guide mechanism, and the top of the smear frame 11 is connected to the bottom of the discharge frame 9, and the bottom of the smear frame 11 is flush with the bottom of the ultrasound probe 1, and the coupling agent in the discharge frame 9 falls on the patient's skin through the smear frame 11, and then passes through the smear frame 11 The coupling agent on the patient's skin is smoothed by moving, so that the coupling agent is evenly distributed on the patient's skin surface; a connecting block 12 is also connected to the guide mechanism, and the connecting block 12 slides through the top of the smear frame 11; a plurality of rubber rods 13 are connected to the bottom of the connecting block 12 at intervals; a vibrator 14 is installed on the left side of the discharge frame 9, and the vibration axis of the vibrator 14 is connected to the connecting block 12. The vibrator 14 is used to drive the connecting block 12 and the rubber rod 13 to vibrate to remove bubbles in the coupling agent, thereby reducing the air gap between the ultrasonic probe 1 and the skin, thereby improving the transmission efficiency of ultrasonic waves.

[0033] See also Figure 3 As shown, the moving mechanism includes a servo motor 701, a screw rod 702 and a nut 703; the servo motor 701 is connected to the upper right side of the liquid storage tank 2; the screw rod 702 is connected to the output shaft of the servo motor 701, and the bottom end of the screw rod 702 is rotatably connected to the lower right side of the liquid storage tank 2, and a nut 703 connected to the magnetic ring II 6 is threadedly provided on the screw rod 702. The screw rod 702 is driven to rotate by the servo motor 701, so that the screw rod 702 can drive the nut 703 and the magnetic ring II 6 to move.

[0034] See also Figure 3-Figure 5As shown, the guiding mechanism includes a guide rail Ⅰ1001, a slide plate Ⅰ1002, a guide rail Ⅱ1003 and a slide plate Ⅱ1004; two guide rails Ⅰ1001 are symmetrically installed on the discharge frame 9; a slide plate Ⅰ1002 is slidably arranged on the guide rail Ⅰ1001, and a damping is arranged between the guide rail Ⅰ1001 and the slide plate Ⅰ1002, so as to increase the friction between the guide rail Ⅰ1001 and the slide plate Ⅰ1002, so as to prevent the slide plate Ⅰ1002 from naturally falling off from the guide rail Ⅰ1001 due to the gravity of the smearing frame 11; the front and rear two slide plates Ⅰ1002 are respectively connected to the front and rear sides of the smearing frame 11; the guide rail Ⅱ1003 is symmetrically connected to the front and rear of the left side of the discharge frame 9; the slide plate Ⅱ1004 is slidably arranged on the guide rail Ⅱ1003, and the bottom of the slide plate Ⅱ1004 is connected to the top of the connecting block 12.

[0035] When in use, first hold the handle 4 and lift it upwards to pull the piston 3 out of the liquid storage tank 2, then add a proper amount of coupling agent into the liquid storage tank 2 for loading, and then hold the handle 4 and push it back downwards to insert the piston 3 back into the original position in the liquid storage tank 2, then hold the ultrasonic probe 1 and make its bottom contact with the patient's skin surface, and at the same time make the bottom of the wiping frame 11 also contact with the patient's skin surface, and then push the ultrasonic probe 1 to move right on the patient's skin, thereby driving the liquid storage tank 2, the discharge pipe 8, the discharge frame 9 and the wiping frame 11 to move right synchronously, and at the same time start the vibrator 14 to drive the connecting block 12 and the rubber rod 13 to vibrate up and down at high frequency. At the same time, the servo motor 701 is started to drive the screw rod 702 to rotate, so that the screw rod 702 drives the nut 703 to move downward, thereby driving the magnetic ring II 6 to move downward, so that the magnetic ring II 6 drives the magnetic ring I 5 and the piston 3 to move downward synchronously through magnetic attraction (here the force generated by the magnetic attraction must be greater than the friction between the piston 3 and the inner wall of the liquid storage tank 2, so that the magnetic ring II 6 can drive the magnetic ring I 5 and the piston 3 to move downward synchronously through magnetic attraction), so that the piston 3 squeezes the coupling agent in the liquid storage tank 2, and the coupling agent in the liquid storage tank 2 flows into the discharge pipe 8 and the discharge frame 9 in turn after being squeezed, so that the coupling agent is squeezed in the discharge frame 9. The soft plate 901 blocks and accumulates. After a certain amount of coupling agent accumulates in the discharge frame 9, the coupling agent will gradually exert pressure to squeeze the soft plate 901 until it is deformed and opened. In this way, the coupling agent in the discharge frame 9 can be evenly dropped down into the smear frame 11, thereby preventing the coupling agent in the discharge frame 9 from falling down from a single position into the smear frame 11. Finally, the coupling agent will fall onto the patient's skin through the smear frame 11. In this way, the coupling agent in the liquid storage tank 2 can be automatically discharged, and the extruded coupling agent can be evenly dropped onto the patient's skin surface for use by medical staff. When the rubber rod 13 contacts the coupling agent on the patient's skin, The rubber rod 13 will squeeze the coupling agent on the patient's skin through high-frequency up and down vibrations to remove the bubbles in the coupling agent. Removing the bubbles in the coupling agent can help reduce the air gap between the ultrasound probe 1 and the skin after the coupling agent is applied, thereby improving the transmission efficiency of the ultrasound wave. After the coupling agent is squeezed by the rubber rod 13 at high frequency, as the smear frame 11 passes over the patient's skin, the smear frame 11 will evenly smear the pressed coupling agent on the patient's skin. In this way, the coupling agent on the patient's skin can be automatically smoothed, so that the coupling agent is evenly distributed on the surface of the patient's skin.Afterwards, as the ultrasonic probe 1 passes over the coupling agent applied on the patient's skin, the ultrasonic probe 1 can be used to generate an image of the patient's internal structure by transmitting and receiving ultrasonic waves, and then the patient's internal condition is checked. After the patient's internal condition is checked, the vibrator 14 and the servo motor 701 are turned off. As the servo motor 701 stops driving the screw rod 702 to rotate, the nut 703, the magnetic ring II 6, the magnetic ring I 5 and the piston 3 stop moving downward, so that the piston 3 stops squeezing the coupling agent in the liquid storage tank 2, and then the coupling agent in the liquid storage tank 2 stops flowing into the discharge pipe 8 and the discharge frame 9 after being no longer squeezed. In this way, when the coupling agent in the discharge frame 9 is When the squeezing force of the mixture on the soft board 901 is less than the deformation force of the soft board 901 itself, the soft board 901 itself will return to its original state, so that the soft board 901 blocks the remaining coupling agent in the discharge frame 9, and then the ultrasonic probe 1 is held and its bottom is separated from the patient's skin surface, and the bottom of the wiping frame 11 is also separated from the patient's skin surface, and then the wiping frame 11 is pulled downward to pull out the slide plate Ⅰ1002 out of the guide rail Ⅰ1001, and then the wiping frame 11 and the slide plate Ⅰ1002 are cleaned, and the rubber rod 13 and the lower side of the ultrasonic probe 1 are cleaned, and then the slide plate Ⅰ1002 is inserted back into the guide rail Ⅰ1001, so as to drive the wiping frame 11 to reset; When the coupling agent in the liquid storage tank 2 is used up, the servo motor 701 is started to drive the screw rod 702 to rotate in the opposite direction, so that the screw rod 702 drives the nut 703 to move upward and reset, thereby driving the magnetic ring II 6 to move upward and reset, so that the magnetic ring II 6 drives the magnetic ring I5 and the piston 3 to move upward and reset synchronously through magnetic attraction, and then repeats the above-mentioned coupling agent loading operation to replenish the coupling agent.

[0036] See also Figure 6 As shown, it also includes a supporting mechanism, which includes a fixed block 15, a rotating shaft 16 and a roller 17; the fixed block 15 is symmetrically connected to the front and back of the right side of the discharge frame 9; the rotating shaft 16 is rotatably connected to the fixed block 15, and a damping is provided between the contact surface of the fixed block 15 and the rotating shaft 16, so that there is a certain friction force between the contact surface of the fixed block 15 and the rotating shaft 16; the rotating shaft 16 is provided with a roller 17 for supporting the liquid storage tank 2.

[0037] By providing a supporting mechanism, when the ultrasonic probe 1 is held and its bottom is in contact with the patient's skin surface, the roller 17 can be in contact with the patient's skin surface. In this way, the roller 17 can be used to support the discharge frame 9, the discharge pipe 8 and the liquid storage tank 2, so as to stabilize the ultrasonic cardiography left heart angiography examination device to prevent the ultrasonic cardiography left heart angiography examination device from tipping over when moving on the patient's skin.

[0038] See also Figure 7 and Figure 8As shown, it also includes an arc-shaped rubber block 19; a slot 18 is opened on the upper right side of the skateboard Ⅰ1002, and the discharge frame 9 is symmetrically connected with the arc-shaped rubber block 19 front and back. When the arc-shaped rubber block 19 is inserted into the slot 18, it is used to limit the skateboard Ⅰ1002, and when the arc-shaped rubber block 19 leaves the slot 18, the limit on the skateboard Ⅰ1002 is released.

[0039] By setting the arc-shaped rubber block 19, when the smear frame 11 is pulled downward to pull out the slide plate Ⅰ1002 from the guide rail Ⅰ1001, the slide plate Ⅰ1002 will squeeze the arc-shaped rubber block 19 to deform, so that the arc-shaped rubber block 19 leaves the slot 18, so that the arc-shaped rubber block 19 releases the limit on the slide plate Ⅰ1002. When the slide plate Ⅰ1002 is separated from the arc-shaped rubber block 19, the arc-shaped rubber block 19 returns to its original state; when the slide plate Ⅰ1002 is inserted back into the guide rail Ⅰ1001, When the sliding plate Ⅰ1002 contacts the arc-shaped rubber block 19, thereby driving the smear frame 11 to reset, the sliding plate Ⅰ1002 will contact the arc-shaped rubber block 19. At this time, the sliding plate Ⅰ1002 will squeeze the arc-shaped rubber block 19 to deform. When the arc-shaped rubber block 19 is aligned with the card slot 18, the arc-shaped rubber block 19 returns to its original state. The arc-shaped rubber block 19 will be stuck in the card slot 18 and limit the sliding plate Ⅰ1002, further preventing the sliding plate Ⅰ1002 from detaching from the guide rail Ⅰ1001, thereby reinforcing the sliding plate Ⅰ1002 and the smear frame 11.

[0040] See also Fig. 9 As shown, it also includes a universal rod 20, a U-shaped plate 21 and a screw 22; one end of the universal rod 20 is connected to the front upper side of the ultrasound probe 1; the other end of the universal rod 20 is connected to the U-shaped plate 21, and the U-shaped plate 21 is used to buckle on the edge of the bed to stabilize the ultrasound probe 1; the bottom of the U-shaped plate 21 is threadedly installed with a screw 22, and the screw 22 is used to fix the U-shaped plate 21 to the edge of the bed.

[0041] When in use, the U-shaped plate 21 can be buckled on the edge of the bed, and then the screw rod 22 can be twisted and rotated to make the screw rod 22 clamp the edge of the bed, so as to fix the U-shaped plate 21. Later, when the medical staff moves the ultrasonic probe 1, the distance between the ultrasonic probe 1 and the U-shaped plate 21 changes, so the universal rod 20 will adaptively deform. When the medical staff needs to loosen the ultrasonic probe 1 to perform other actions, the ultrasonic probe 1 can be directly loosened. At this time, the ultrasonic probe 1 is pulled by the universal rod 20 to maintain the state of the ultrasonic probe 1 to prevent the ultrasonic probe 1 from being in an abnormal state such as tipping, deflection, and falling. In this way, it is convenient for the medical staff to loosen the ultrasonic probe 1 to perform other actions, so that there is no need to hold the ultrasonic probe 1 all the time to work; after the internal condition of the patient is checked, the screw rod 22 is twisted and rotated in the opposite direction to make the screw rod 22 loosen the edge of the bed, so as to release the fixation of the U-shaped plate 21, and then the U-shaped plate 21 can be removed from the edge of the bed.

[0042] See also Fig.10 As shown, it also includes a speed detection module 23, a resistance reduction sleeve 24 and an electric control valve 25; the speed detection module 23 is connected to the front right side of the discharge frame 9, and the detection unit of the speed detection module 23 is connected to the front rotating shaft 16, so that the speed detection module 23 can detect the speed of the front rotating shaft 16, and the speed detection module 23 is internally provided with a control unit, the control unit is used to control the start and stop of other linkage parts, and the control unit is electrically connected to the servo motor 701; the outer sides of the two rollers 17 are both covered with resistance reduction sleeves 24, and by setting the resistance reduction sleeves 24, the friction force of the rollers 17 rolling on the patient's skin can be reduced; the discharge pipe 8 is provided with an electric control valve 25, and the control unit in the speed detection module 23 is electrically connected to the electric control valve 25.

[0043] When the roller 17 is rolled on the patient's skin with the resistance reduction sleeve 24, if there is no coupling agent on the skin where the roller 17 is located, the friction between the skin and the resistance reduction sleeve 24 is greater than the friction between the fixed block 15 and the rotating shaft 16. Therefore, the roller 17 can roll on the skin, thereby driving the rotating shaft 16 to rotate, so that the speed detection module 23 can detect the speed of the rotating shaft 16. When the speed detection module 23 detects that the speed of the rotating shaft 16 is greater than the preset value, the control unit in the speed detection module 23 will control the electric control valve 25 to open, so that the coupling agent in the discharge pipe 8 can pass normally, so that the coupling agent passing through the discharge pipe 8 can be applied to the patient's skin, and when the speed detection module 23 detects that the speed of the rotating shaft 16 gradually increases or decreases, the control unit in the speed detection module 23 will control the servo motor 701 to drive the screw rod 702 to accelerate or decelerate to rotate, thereby speeding up or slowing down the nut 703 and the magnetic ring II. 6. The descending speed of the magnetic ring Ⅰ5 and the piston 3 speeds up or slows down the discharge speed of the coupling agent in the liquid storage tank 2, so that the discharge speed of the coupling agent in the liquid storage tank 2 can match the moving speed of the ultrasonic probe 1 on the patient's skin, avoiding the discharge speed of the coupling agent in the liquid storage tank 2 being too fast or too slow; if the skin where the roller 17 is located has been coated with coupling agent (the coupling agent can reduce the friction between the resistance reduction sleeve 24 and the skin), the friction between the skin and the resistance reduction sleeve 24 is less than the friction between the fixed block 15 and the rotating shaft 16, so that the roller 17 slides on the skin and does not roll, which causes the speed detection module 23 to detect that the speed of the rotating shaft 16 will continue to be less than the preset value, so that the control unit in the speed detection module 23 cannot control the electric control valve 25 to open, and then the coupling agent in the discharge pipe 8 cannot pass normally, so that the skin that has been coated with coupling agent will not be coated with coupling agent repeatedly, thereby preventing the coupling agent from being wasted.

[0044] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
