[0002] Color Doppler ultrasound is a device that uses Doppler ultrasound technology and the principle of ultrasound echo to simultaneously collect information on blood flow, tissue movement, and imaging of human organs and tissues.

Detailed Implementation

[0027] In the following description, embodiments of the invention will be described with reference to the accompanying drawings. In the description below, the same modules are denoted by the same reference numerals. Where the same reference numerals are used, their names and functions are also the same. Therefore, their detailed description will not be repeated.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute a limitation thereof.

[0029] Figure 1 The structure of an intelligent color ultrasound device provided according to an embodiment of the present invention is shown.

[0030] like Figure 1As shown, the intelligent color Doppler ultrasound device provided in this embodiment of the invention includes a color Doppler ultrasound bed 1, a movable frame body 2, a transverse movement mechanism 3, a transverse drive assembly 4, a longitudinal movement mechanism 5, a longitudinal drive assembly 6, and a probe 7. The movable frame body 2 spans across the color Doppler ultrasound bed 1. Electric roller mounting plates 2-1 are fixed to the bottom of the two free ends of the movable frame body, and two electric rollers 2-2 are installed at the bottom of each electric roller mounting plate 2-1. The electric rollers 2-2 enable movement along the length direction of the color Doppler ultrasound bed 1. The transverse movement mechanism 3 and the transverse drive assembly 4 are fixed to the movable frame body 2, and the transverse drive assembly 4 is used to drive the transverse movement mechanism 3 to move along the width direction of the color Doppler ultrasound bed 1. The longitudinal movement mechanism 5 and the longitudinal drive assembly 6 are fixed to the transverse movement mechanism 3, and the longitudinal drive assembly 6 is used to drive the longitudinal movement mechanism 5 to move in a direction perpendicular to the color Doppler ultrasound bed 1. The probe 7 is fixed to the longitudinal movement mechanism 5.

[0031] Using the movement direction of the moving frame body 2 as the X-axis, the movement direction of the transverse moving mechanism 3 as the Y-axis, and the movement direction of the longitudinal moving mechanism 5 as the Z-axis, the probe 7 can achieve three-dimensional movement along the X, Y, and Z axes through the cooperation of the three.

[0032] The electric roller 2-2 uses the wheels of an electric vehicle, with the hub motor installed inside the roller to achieve linear motion. If omnidirectional motion of the electric roller 2-2 is desired, a Mecanum wheel is used.

[0033] Figure 2 The assembly relationship between the lateral movement mechanism and the lateral drive assembly provided according to an embodiment of the present invention is shown.

[0034] like Figure 2 As shown, the lateral movement mechanism 3 includes an arc guide rail 3-1, an arc guide rail slider 3-2, and a lateral drive connecting plate 3-3. One side of the arc guide rail slider 3-2 is slidably connected to the arc guide rail 3-1, and the other side of the arc guide rail slider 3-2 is fixedly connected to the lateral drive connecting plate 3-3. The lateral drive connecting plate 3-3 moves laterally by sliding the arc guide rail slider 3-2 on the arc guide rail 3-1.

[0035] The transverse drive assembly 4 includes a transverse drive motor 4-1 and a transverse drive screw 4-2. The transverse drive motor 4-1 and the transverse drive screw 4-2 are respectively fixed on the movable frame body 2. The output end of the transverse drive motor 4-1 is connected to the lead screw of the transverse drive screw 4-2 through a coupling. A sliding groove 3-4 is provided on the transverse drive connecting plate 3-3 in a direction perpendicular to the color ultrasound bed 1. The lead screw nut 4-3 of the transverse drive screw 4-2 is slidably engaged with the sliding groove 3-4, so that the transverse drive connecting plate 3-3 slides up and down.

[0036] The transverse drive motor 4-1 drives the transverse drive screw 4-2 to rotate, causing the screw nut 4-3 to move laterally. The screw nut 4-3 drives the transverse drive connecting plate 3-3 to move laterally, thereby causing the arc guide rail slider 3-2 to slide along the arc guide rail 3-1. During the sliding process of the arc guide rail slider 3-2, the transverse drive connecting plate 3-3 can adaptively adjust its height.

[0037] When patient 9 lies on the ultrasound bed 1, the height gradually decreases from the abdomen to the sides of the waist. Therefore, this invention uses a circular arc guide rail 3-1. When the circular arc guide rail slider 3-2 slides along the circular arc guide rail 3-1 to different heights, the probe 7 can move more in line with the human body curve by sliding up and down in the groove 3-4 through the screw nut 4-3, thus improving the fit between the probe 7 and the patient's body surface.

[0038] The longitudinal moving mechanism includes two linear guide rails 5-1, two linear guide rail sliders 5-2, and a longitudinal drive connecting plate 5-3. The two linear guide rails 5-1 are vertically fixed on the transverse drive connecting plate 3-3 and located on both sides of the slide groove 3-4. The two linear guide rail sliders 5-2 slide on their respective linear guide rails 5-1.

[0039] The longitudinal drive assembly 6 includes a longitudinal drive motor 6-1 and a longitudinal drive screw 6-2. The longitudinal drive motor 6-1 and the longitudinal drive screw 6-2 are respectively fixed on the transverse drive connecting plate 3-3 and located between two linear guide rails 5-1. The output end of the longitudinal drive motor 6-1 is connected to the lead screw of the longitudinal drive screw 6-2 through a coupling. The lead screw nut of the longitudinal drive screw 6-2 and the two linear guide rail sliders 5-2 are respectively fixedly connected to one side of the longitudinal drive connecting plate 5-3. The probe 7 is fixed on the other side of the longitudinal drive connecting plate 5-3.

[0040] The longitudinal drive motor 6-1 drives the longitudinal drive screw 6-2 to rotate, the longitudinal drive screw 6-2 drives the screw nut to move up and down, the screw nut drives the longitudinal drive connecting plate 5-3 to move up and down, and the longitudinal drive connecting plate 5-3 drives the two linear guide sliders 5-2 to slide on the two linear guides 5-1, so that the probe 7 can contact the patient's body surface 9.

[0041] In a preferred embodiment of the present invention, the intelligent color ultrasound device provided in the present invention further includes a flexible adjustment mechanism 8, which is connected between the probe and the longitudinal drive connecting plate and plays a role in buffering and shock absorption.

[0042] Figure 3 The structure of a flexible adjustment mechanism provided according to an embodiment of the present invention is shown.

[0043] like Figure 3As shown, the flexible adjustment mechanism includes a flexible frame body 8-1, guide posts 8-2, guide sleeves 8-3, springs 8-4, and a flexible connecting plate 8-5. The flexible frame body 8-1 is fixedly connected to the longitudinal drive connecting plate 5-3. The flexible frame body 8-1 is a hollow cuboid structure. The guide posts 8-2 are vertically installed inside the flexible frame body 8-1, and their upper and lower ends are fixedly connected to the flexible frame body 8-1, respectively. The guide sleeves 8-3 and springs 8-4 are respectively fitted onto the guide posts 8-2. Spring 8-4 is located above guide sleeve 8-3. One end of spring 8-4 abuts against guide sleeve 8-3, and the other end abuts against flexible frame body 8-1. The upper end of flexible connecting plate 8-5 is fixedly connected to guide sleeve 8-3, and the lower end of flexible connecting plate 8-5 is fixedly connected to probe 7. Probe 7 can move flexibly in a direction perpendicular to color ultrasound bed 1 through the cooperation of guide sleeve 8-3 and guide post 8-2. When an external force is applied to probe 7, spring 8-4 can drive flexible connecting plate 8-5 to balance the external force.

[0044] A first flexible hinge 8-7 and / or a second flexible hinge 8-8 are provided at the lower end of the flexible connecting plate 8-5 near the probe 7. The first flexible hinge 8-7 and the second flexible hinge 8-8 play the role of elastic deformation.

[0045] The first flexible hinge 8-7 includes a first stress unloading groove 8-7-1 and a second stress unloading groove 8-7-2. The grooves of the first stress unloading groove 8-7-1 and the second stress unloading groove 8-7-2 are oriented in the thickness direction of the flexible connecting plate 8-5. The openings of the first stress unloading groove 8-7-1 and the second stress unloading groove 8-7-2 are located at opposite positions on two surfaces of the flexible connecting plate 8-5, i.e., the openings of the first stress unloading groove 8-7-1 and the second stress unloading groove 8-7-2 have the same height. The lengths of the first stress unloading groove 8-7-1 and the second stress unloading groove 8-7-2 are the same as the width of the flexible connecting plate 8-5. The total depth of the first stress unloading groove 8-7-1 and the second stress unloading groove 8-7-2 is less than the thickness of the flexible connecting plate 8-5, thereby giving the first flexible hinge 8-7 elasticity in the thickness direction of the flexible connecting plate 8-5.

[0046] The second flexible hinge 8-8 includes a third stress unloading groove 8-8-1 and a fourth stress unloading groove 8-8-2. The slotting direction of the third stress unloading groove 8-8-1 and the fourth stress unloading groove 8-8-2 is the width direction of the flexible connecting plate 8-5. The openings of the third stress unloading groove 8-8-1 and the fourth stress unloading groove 8-8-2 are located at opposite positions on two sides of the flexible connecting plate 8-5, that is, the heights of the openings of the third stress unloading groove 8-8-1 and the fourth stress unloading groove 8-8-2 are the same. The lengths of the third stress unloading groove 8-8-1 and the fourth stress unloading groove 8-8-2 are the same as the thickness of the flexible connecting plate 8-5. The total depth of the third stress unloading groove 8-8-1 and the fourth stress unloading groove 8-8-2 is less than the width of the flexible connecting plate 8-5, thereby making the second flexible hinge 8-9 elastic in the width direction of the flexible connecting plate 8-5.

[0047] The first flexible hinge 8-7 and the second flexible hinge 8-8 can play an elastic deformation role in two vertical directions to counteract external forces and make the probe 7 more stable during inspection.

[0048] Figures 4-6 The structures of the probes provided according to embodiments of the present invention are shown respectively.

[0049] like Figures 4-6 As shown, the probe 7 provided in this embodiment of the invention includes a probe housing 7-1. A coupling fluid output chamber 7-2, a coupling fluid recovery chamber 7-3, and an ultrasonic transmission chamber 7-4 are provided inside the probe housing 7-1. A coupling fluid output tank 7-5 and a coupling fluid recovery tank 7-6 are respectively provided on the probe housing 7-1. The coupling fluid output tank 7-5 and the coupling fluid output chamber 7-2 are connected through a coupling fluid output pipe assembly 7-7. The coupling fluid recovery tank 7-6 and the coupling fluid recovery chamber 7-3 are connected through a coupling fluid recovery pipe assembly 7-8. A coupling fluid output pump 7-9 and a coupling fluid recovery pump 7-10 are installed outside the probe housing 7-1. The coupling fluid output pump 7-9 is connected to the coupling fluid output chamber 7-2, and the coupling fluid recovery pump 7-10 is connected to the coupling fluid recovery chamber 7-3.

[0050] The coupling fluid output pump 7-9 is actually an additional pump that generates positive pressure in the coupling fluid output chamber 7-2, causing the coupling fluid in the coupling fluid output chamber 7-2 to flow out from the coupling fluid output tube group 7-7 and come into contact with the patient's body surface. A small cavity is formed between the coupling fluid output tank 7-5 and the patient's body surface, and the coupling fluid can only flow in the small cavity. When the probe 7 moves, it can prevent the coupling fluid from flowing to other parts of the patient's body surface.

[0051] The coupling fluid recovery pump 7-10 is actually a negative pressure pump, which generates negative pressure in the coupling fluid recovery chamber 7-3. The coupling fluid recovery tank 7-6 plays the role of collecting coupling fluid. The coupling fluid collected in the coupling fluid recovery tank 7-6 flows back to the coupling fluid recovery chamber 7-3 through the coupling fluid recovery pipe 7-8.

[0052] The automatic output and recovery of coupling fluid by the probe 7 is achieved through the coupling fluid output pump 7-9 and the coupling fluid recovery pump 7-10. This eliminates the need for the ultrasound physician to manually apply coupling fluid to the patient 9 and also avoids coupling fluid residue on the patient 9's body, providing convenience for both the patient 9 and the ultrasound physician.

[0053] The coupling solution can be physiological saline, alcohol, or distilled water.

[0054] An acoustic lens 7-4-1, a matching layer 7-4-2, a padding layer 7-4-3, an array element 7-4-4, and a protective layer 7-4-5 are sequentially arranged inside the ultrasonic transmission cavity 7-4.

[0055] The acoustic lens 7-4-1 comes into contact with the patient's body surface 9, which serves to converge or disperse sound waves.

[0056] The matching layer 7-4-2 is used to achieve acoustic impedance matching between the probe and the patient's body surface 9, reducing multiple reflections caused by the difference in acoustic impedance between the body surface and the probe, so that ultrasound can effectively enter the human body and realize the examination of human tissues.

[0057] The padding layer 7-4-3 mainly serves to reduce or eliminate interference caused by multiple reflections of ultrasound within the ultrasonic transmission cavity 7-4, increase the damping of the array element 7-4-4, narrow the transmitted pulse, and thus improve resolution.

[0058] The array element 7-4-4 is a piezoelectric crystal used to emit and receive ultrasonic waves, and to perform sound-to-electric and electro-acoustic conversion. That is, when emitting ultrasonic waves, it converts electrical signals into ultrasonic waves, and when receiving ultrasonic waves, it converts ultrasonic waves into electrical signals.

[0059] The protective layer 7-4-5 is used to protect the matching layer 7-4-2, the padding layer 7-4-3 and the protective array element 7-4-4.

[0060] The coupling fluid output chamber 7-2 and the ultrasound transmission chamber 7-4 are arranged opposite to each other, and the coupling fluid recovery chamber 7-3 forms a closed annular structure, placing the coupling fluid output chamber 7-2 and the ultrasound transmission chamber 7-4 in the middle. The coupling fluid recovery chamber 7-3 surrounds the coupling fluid output chamber 7-2, which can fully recover the coupling fluid and prevent it from remaining on the patient 9.

[0061] As a preferred embodiment, the coupling fluid recovery chamber 7-3 forms an unclosed annular structure surrounding the coupling fluid output chamber 7-2 and the ultrasonic transmission chamber 7-4. A weight reduction groove 7-11 is formed on the probe housing 7-1 corresponding to the unclosed part of the coupling fluid recovery chamber 7-3. By setting the weight reduction groove 7-11, the overall weight of the probe 7 is reduced, thereby achieving lightweighting.

[0062] Mounting plates 8-6 are integrally formed on both sides of the lower end of the flexible connecting plate 8-5. Through holes 8-6-1 are respectively opened on the two mounting plates 8-6. Threaded blind holes 7-12 are respectively opened on the probe housing 7-1 at the positions corresponding to the two through holes 8-6-1. The probe housing 7-1 is fixed to the two mounting plates 8-6 by countersunk screws 8-9.
