Description

Technical Field

[0001] The present invention belongs to the field of ultrasonic contrast examination devices, and in particular relates to a multifunctional cardiac color ultrasonic contrast examination device. Background Art

[0002] Cardiac colorimetric ultrasound imaging is an important clinical diagnostic imaging method. It typically requires the use of a contrast agent containing microbubbles to enhance ultrasound image contrast, enabling better visualization of the heart's internal structure and function. To achieve optimal imaging, the contrast agent and gas must be thoroughly and evenly mixed to produce a microbubble liquid with consistent particle size and stable distribution. Furthermore, contrast agent loss must be minimized during the mixing and injection process to ensure image quality and examination accuracy.

[0003] Currently, in cardiac ultrasound angiography, it is usually necessary to fully mix the contrast agent with gas to form a uniform microbubble solution to improve the contrast and clarity of ultrasound imaging. However, the stirring devices commonly used in the prior art have the following drawbacks:

[0004] First, most traditional stirring devices simply rely on stirring action in a single direction, which has low stirring efficiency and unsatisfactory mixing effect, easily leading to uneven mixing of contrast agent and gas, and inconsistent distribution of generated microbubble particle size, thus affecting the imaging quality and diagnostic accuracy of subsequent examinations.

[0005] Secondly, existing equipment has poor control over the contrast agent's sealing during the mixing process, which can easily lead to liquid leakage or gas escape during mixing, resulting in a decrease in the mixed concentration and affecting the examination effect. Furthermore, some devices require manual or additional mechanisms to inject the contrast agent after mixing, which is not only cumbersome but also easily leads to contrast agent waste during the transfer process, reducing liquid utilization.

[0006] In view of this, the present invention is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] See also Figure 1-5 As shown, in this embodiment, a multifunctional cardiac color ultrasound angiography device is provided, comprising a barrel 1, a display device being mounted on the top of the barrel 1, a suspension mechanism being fixedly connected to one side of the barrel 1, a probe 2 being placed inside the suspension mechanism, a stirring mechanism being provided inside the barrel 1, a water outlet being provided at the bottom of the barrel 1, and a water inlet being provided at the top of one side of the outer wall of the barrel 1;

[0036] The stirring mechanism includes a servo motor 3 located above the cylinder 1, the output end of the servo motor 3 is fixedly connected to the stirring shaft 4, a mixing mechanism is provided on the peripheral side of the outer wall of the stirring shaft 4, and a sealing mechanism for sealing the water outlet is slidably connected to the cylinder 1 in the vertical direction.

[0037] The present invention significantly improves the efficiency and sealing reliability of the contrast agent stirring process by installing a stirring mechanism within the cylinder and integrating a sealing mechanism and a mixing mechanism with the stirring mechanism. The mixing mechanism is fixedly connected to the outer wall of the stirring shaft and, as the stirring shaft rotates, drives the stirring plate to perform multi-directional, efficient stirring. This allows the contrast agent and gas to be fully mixed, generating a mixed liquid with uniform and stable microbubbles, thereby improving the imaging quality and diagnostic accuracy of cardiac color Doppler ultrasound examinations.

[0038] The sealing mechanism and the mixing mechanism of the present invention are linked together through the stirring shaft. During the stirring stage, the sealing mechanism effectively closes the water outlet to ensure that the contrast agent is fully mixed in a closed environment. During the injection stage, the sealing mechanism cooperates with the push plate to move downward to form a thrust, which not only opens the water outlet but also pushes out the stirred contrast agent in an orderly manner through the piston structure, thereby achieving efficient injection of the contrast agent and improving the liquid utilization rate during the injection process.

[0039] In this embodiment, the sealing mechanism is fixedly connected to the reciprocating screw 5 at the lower end of the stirring shaft 4, and the circumferential side of the reciprocating screw 5 is threadedly connected to the first nut 6. The vertical upper part of the cylinder 1 is slidably connected to a push plate 7, and the axis of the push plate 7 is provided with a through hole that is compatible with the reciprocating screw 5. In the present invention, the lower end of the stirring shaft 4 is fixedly connected to the reciprocating screw 5, and the reciprocating screw 5 is threadedly connected to the first nut 6. When the servo motor 3 drives the stirring shaft 4 to rotate, the reciprocating screw 5 will also rotate accordingly. Due to the action of the thread, the first nut 6 will move up and down along the axial direction on the reciprocating screw 5. There is a push plate 7 inside the cylinder 1, and the center of the push plate 7 has a through hole, which just fits on the reciprocating screw 5. When the first nut 6 moves up and down, it will drive the push plate 7 to slide up and down together.

[0040] The push plate 7 slides up and down to control the opening and closing of the water outlet. When the push plate 7 moves downward, it blocks the outlet, preventing the contrast agent in the cylinder 1 from leaking out and facilitating mixing. When the contrast agent needs to be discharged, the push plate 7 moves upward, exposing the outlet and allowing the contrast agent to be discharged smoothly.

[0041] This design utilizes the principle of mechanical transmission. Through the cooperation of the reciprocating screw 5 and the nut, the push plate 7 is moved up and down, thereby controlling the opening and closing of the water outlet.

[0042] In this embodiment, a plurality of plates 8 are fixedly connected to the circumferential side of the inner wall of the cylinder 1, and a connecting rod 9 is fixedly connected to the bottom of the plate 8. A sealing plug 10 is provided at the lower end of the connecting rod 9, and a through groove 11 for the sliding of the sealing plug 10 is provided on the opposite sides between the upper and lower sides of the push plate 7. The function of the sealing plug 10 is to control the opening and closing of the water outlet. When the sealing plug 10 is located in the through groove 11, it will block the water outlet to prevent the contrast agent from flowing out, thereby ensuring the sealing inside the cylinder 1 and being suitable for use when stirring the contrast agent. When the sealing plug 10 slides out of the through groove 11, the water outlet is opened, and the contrast agent can be smoothly discharged through the through groove 11 for subsequent inspection operations. This design realizes the switching of the device between different working states by changing the position of the sealing plug 10.

[0043] In this embodiment, an annular groove is formed around the outer wall of the push plate 7, and a sealing ring 12 is disposed within the annular groove, which fits against the inner wall of the cylinder 1. As the push plate 7 slides up and down within the cylinder 1, the sealing ring 12 fits tightly against the inner wall of the cylinder 1. Because the sealing ring 12 is elastic, it can fill the tiny gap between the push plate 7 and the inner wall of the cylinder 1, thereby effectively preventing liquid from leaking through this gap. This design significantly improves the sealing performance of the push plate 7 during sliding, ensuring that the contrast agent inside the cylinder 1 does not leak out during stirring, while also ensuring the sealing of the water outlet when it is closed.

[0044] In the present embodiment, an extension tube 13 is fixedly connected to the top of the through groove 11, and the diameter of the extension tube 13 is the same as that of the through groove 11, and the sealing plug 10 slides inside the through groove 11 along the extension tube 13. The extension tube 13 is installed above the through groove 11, and its internal diameter is consistent with that of the through groove 11, and the sealing plug 10 can slide up and down in the extension tube 13. During the stirring process, the extension tube 13 increases the sliding stroke of the sealing plug 10, so that the sealing plug 10 needs to pass through a longer distance when moving up and down. In this way, the stirring shaft 4 needs to rotate more circles to complete the movement of the sealing plug 10, thereby extending the stirring time of the stirring mechanism. Longer stirring time means that the contrast agent and gas can be mixed more fully, and the distribution of microbubbles is more uniform, thereby improving the stirring effect of the contrast agent.

[0045] Furthermore, in the present application, the push plate 7 achieves up and down sliding in the vertical direction by cooperating with the reciprocating screw 5 and the first nut 6. When the push plate 7 moves upward, the sealing plug 10 provided on the push plate 7 gradually disengages from the through groove 11, so that the through groove 11 is in an open state, and the contrast agent that has been stirred can flow out smoothly through the through groove 11. Then the push plate 7 slides downward in the opposite direction, and the sealing plug 10 slides along the extension tube 13 and the inside of the through groove 11 and re-blocks the through groove 11, thereby achieving sealing of the water outlet. In the process of the push plate 7 continuing to move downward, the push plate 7 acts as a piston to form a downward compression thrust on the inside of the cylinder 1. Under the action of this thrust, the contrast agent that has been stirred in the cylinder 1 is effectively pushed out through the water outlet and directly injected into the patient's body through the connected delivery pipeline.

[0046] This structural design not only achieves leakage-free and rapid discharge of the contrast agent after stirring, but also simplifies the transportation process of the contrast agent from stirring to injection through the piston-type pressure-delivery function of the push plate 7, reduces intermediate operation links, reduces the risk of pollution and waste, and improves the injection speed and efficiency.

[0047] In this embodiment, the mixing mechanism includes a connecting plate 14 fixedly connected to the upper peripheral side of the outer wall of the stirring shaft 4, a positioning rod 15 fixedly connected to the lower side of the connecting plate 14, an external thread is provided on the peripheral side of the outer wall of the stirring shaft 4, a second nut 16 is threadedly connected to the outer wall, a connecting ring 17 is rotatably connected to the peripheral side of the second nut 16, a plurality of stirring plates 18 are fixedly connected to the peripheral side of the connecting ring 17, and positioning holes that are compatible with the positioning rod 15 are opened through the opposite side of the stirring plates 18. The outer wall of the stirring shaft 4 is provided with an external thread, and the second nut 16 is threadedly connected thereto. When the stirring shaft 4 is rotated under the drive of the servo motor 3, due to the cooperation between the external thread and the second nut 16, the second nut 16 will generate relative motion in the axial direction of the stirring shaft 4, thereby driving the stirring plates 18 connected thereto to move up and down inside the cylinder 1.

[0048] To ensure that agitating plate 18 remains stable and rotates during its vertical movement, a connecting plate 14 is fixedly attached to the upper circumference of the outer wall of agitating shaft 4. Positioning rods 15 are attached below connecting plate 14. Positioning holes corresponding to positioning rods 15 are provided through opposite sides of agitating plate 18. As agitating shaft 4 rotates, positioning rods 15 restrict radial movement of agitating plate 18, forcing it to slide up and down axially along agitating shaft 4 while rotating with it.

[0049] This design allows the stirring plate 18 to rotate around the stirring shaft 4 during its up and down movement. This combination of rotation and sliding allows the stirring plate 18 to generate a more complex flow in the liquid inside the cylinder 1, thereby more effectively mixing the contrast agent and liquid and improving the uniformity and efficiency of stirring.

[0050] In this embodiment, a guide rod 19 is fixedly connected to the top of the plate body 8, and a guide hole compatible with the guide rod 19 is provided on the opposite side of the second nut 16, and the guide rod 19 is slidably connected in the vertical direction of the guide hole. A number of guide rods 19 are fixedly connected to the inner wall of the cylinder 1, and the length direction of these guide rods 19 is consistent with the axial direction of the stirring shaft 4. A guide hole compatible with the guide rod 19 is provided on the opposite side of the second nut 16, and the guide rod 19 is slidably connected in the guide hole. When the stirring shaft 4 rotates, due to the limitation of the guide rod 19, the second nut 16 cannot rotate with the stirring shaft 4 and can only slide up and down along the axial direction of the guide rod 19. This design fixes the position of the second nut 16 by the guide rod 19, ensuring that the second nut 16 can only move up and down during the rotation of the stirring shaft 4, and will not rotate, thereby achieving the up and down movement effect of the stirring plate 18 inside the cylinder 1.

[0051] In this embodiment, the suspension mechanism includes a connecting frame 20 fixedly connected to one side of the outer wall of the cylinder 1, and a slot is provided on one side of the connecting frame 20 to prevent the handle of the probe 2 from being moved. A connecting frame 20 is fixedly connected to one side of the outer wall of the cylinder 1, and a special slot is designed inside the connecting frame 20 for placing the ultrasound probe 2. The shape and size of the slot are compatible with the handle portion of the probe 2, and the probe 2 can be firmly fixed in the connecting frame 20. When the probe 2 is not in use, it can be placed in the slot of the connecting frame 20. The limiting effect of the slot prevents the probe 2 from shaking or falling during the movement or storage of the device, thereby protecting the probe 2 from damage. This design provides a stable and safe storage location for the probe 2 through the setting of the connecting frame 20, which facilitates the management and protection of the probe 2.

[0052] In this embodiment, a handle 21 is provided at the first edge above the cylinder 1, and four universal wheels 22 are fixedly connected to the bottom of the cylinder 1. The detection device can be moved by the arrangement of the universal wheels 22 and the handle 21.

[0053] In this embodiment, the display device includes a display screen 23, a bracket 24 is fixedly connected between the display screen 23 and the cylinder 1, a control panel is provided at the second edge above the cylinder 1, and a plurality of buttons are provided on the control panel.

Any structural changes made under the guidance of the present invention, which have the same or similar technical solutions as the present invention, should be understood to fall within the scope of protection of the present invention. The technologies, shapes, and structural parts not described in detail in the present invention are all well-known technologies.
