Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a clinical application method of an ultrasound contrast injection system. Background Art

[0002] Ultrasound contrast imaging is a technique that uses contrast agents to enhance backscattered echoes, significantly improving the resolution, sensitivity and specificity of ultrasound diagnosis. With the improvement of instrument performance and the emergence of new acoustic contrast agents, ultrasound contrast imaging can effectively enhance the ultrasound images and blood flow Doppler signals of solid organs such as the myocardium, liver, kidney, and brain, and reflect and observe the blood perfusion of normal and diseased tissues. It has become a very important and promising development direction for ultrasound diagnosis. Some people regard it as the third revolution after two-dimensional ultrasound, Doppler and color blood flow imaging.

[0003] Ultrasound contrast imaging currently uses two different liquid medicines, one is contrast agent, and the other is saline or liquid medicine for cleaning. Therefore, two different syringes are used for injection. The evaluation standard is to observe the direct image of the development, and in order to obtain the image, we generally need to inject the contrast agent first.

[0004] After searching, a Chinese patent discloses a high-pressure contrast syringe syringe pipeline system (authorization publication number is CN208943114U), including a syringe, a drug inlet passage, an exhaust passage, a drug outlet passage, a first medical three-way valve and a second medical three-way valve. The inlet of the first medical three-way valve is connected to the drug inlet passage, an outlet of the first medical three-way valve is connected to the syringe, and the other outlet of the first medical three-way valve is connected to the inlet of the second medical three-way valve. An outlet of the second medical three-way valve is connected to the drug outlet passage, and the other outlet of the second medical three-way valve is connected to the exhaust passage; the syringe forms an exhaust pipeline with the exhaust passage through the first medical three-way valve, and the syringe forms a drug outlet pipeline with the first medical three-way valve, the second medical three-way valve and the drug outlet passage.

[0005] However, in actual use, the existing contrast agent injection is either manually pushed or pushed by a single injection device, which results in only one syringe being able to be injected using the injection device, while the other syringe needs to be manually pushed, which brings great inconvenience to the contrast agent. Summary of the invention

The push injection process is more stable, reliable and comfortable, and the syringes can be switched at any time to replace two different medicines for injection, which is convenient and efficient.

[0043] The two sets of side plates 1 and the connecting plate 2 are fixedly connected together by locking bolts, and the side surface of the fixing plate 3 is embedded with fixing bolts;

[0044] A mounting hole is provided inside the side plate 1, and a movable bearing is embedded inside the mounting hole;

[0045] There are two groups of driving motors 5;

[0046] A clinical application method of an ultrasound contrast injection system specifically comprises the following steps:

[0047] Step 1: Establish a peripheral venous infusion channel (usually the median cubital vein);

[0048] Step 2: Connect the intravenous indwelling needle to the three-way pipeline structure;

[0049] Step 3: Draw a certain amount of ultrasound contrast agent microbubble suspension after shaking according to the patient's condition, and draw 5ml-10ml of normal saline;

[0050] Step 4: Connect the syringes for extracting ultrasound contrast agent and saline to the three-way pipe respectively. The connection positions are: the ultrasound contrast agent is in the same direction as the outlet of the three-way pipe, and the saline is perpendicular to the outlet of the three-way pipe;

[0055] Step 9: After the automatic injection of normal saline is completed, the adjustable precise injection process of ultrasound contrast agent is completed.

[0056] The specific implementation method is as follows: when in use, two different kinds of liquid medicine are placed in the first syringe 10 and the second syringe 11 respectively, and the movable block 14 is pulled downward to compress the action spring 15, and then the core rod 12 is placed in the core rod clamping plate 13, and the movable block 14 is released. The compressed action spring 15 will push the movable block 14 upward to make it engage with the core rod 12, thereby engaging the core rod 12 with the core rod clamping plate 13, and then clamp the first syringe 10 and the second syringe 11. The operator turns on the power switch, sets various parameters and clicks start, and the drive motor 5 will drive the gear 73 through the coupling 61 and the reduction gear 62. While the gear 73 rotates, it drives the screw rod 71 to rotate, and cooperates with the limit of the guide rail 74, so that the sliding block 72 on the screw rod 71 converts the rotational motion into linear motion, thereby pushing the core rod 12 to move. Rod 12, under the control of the user, the first syringe 10 and the second syringe 11 are pushed at different times. The first syringe 10 and the second syringe 11 are driven by the drive motor 5 to drive the screw 71 to complete the injection of the medicine, reducing the manual injection link, making the operation process simpler, the push injection process is constant and stable and the speed is adjustable, the push injection process is more stable, reliable and comfortable, and the syringe can be switched at any time to replace two different medicines for injection, which is convenient and efficient, and solves the problem of complicated and cumbersome operation of changing medicine when using a single injection device.

[0057] As attached Figure 1 and attached Figure 4 The clinical application method of the ultrasound contrast injection system shown in the figure also includes a speed reduction mechanism 6, which is placed at one end of the side plate 1. The speed reduction mechanism 6 includes a coupling 61, and a speed reduction gear 62 is arranged on one side of the coupling 61. The speed reduction gear 62 is meshed with a gear 73.

[0058] The reduction gear 62 is meshed with the coupling 61 through a tooth-groove manner.

[0059] The specific implementation method is as follows: a group of reduction mechanisms 6 are set at the driving end of the driving motor 5, which control the operation of the driving motor 5. Since the coupling 61 is fixedly connected to the driving motor 5, a reduction gear 62 is provided between the coupling 61 and the gear 73. The reduction of the reduction gear 62 greatly reduces the rotation speed of the driving motor 5, so that the drug solution can flow stably in the first syringe 10 and the second syringe 11, ensuring that the entire injection process is smoother and solving the problem of the drug solution flowing too fast due to the driving motor 5 rotating too fast.

[0060] As attached Figure 7 The ultrasound angiography push injection system based on the injection device shown in the figure also includes a wiping mechanism 16, which is placed on the side surface of the sliding block 72. The wiping mechanism 16 includes a fixed cylinder 17, and a mounting seat 18 is integrally formed at one end of the fixed cylinder 17. A wiping cotton 19 is arranged inside the fixed cylinder 17, and the wiping cotton 19 is fixedly connected to the fixed cylinder 17.

[0061] The specific implementation method is as follows: the mounting seat 18 in the wiping mechanism 16 is installed on the side surface of the sliding block 72, so that the fixed cylinder 17 is sleeved on the outside of the guide rail 74. When the sliding block 72 is in motion, the wiping cotton 19 in the fixed cylinder 17 is in contact with the guide rail 74 at all times. During the reciprocating motion, the wiping cotton 19 wipes and cleans the surface of the guide rail 74, effectively removing impurities and dust accumulated on the outer surface of the guide rail 74, avoiding the sliding of the sliding block 72 on the guide rail 74, ensuring the smooth movement of the sliding block 72, and solving the problem that the impurities accumulated on the guide rail 74 cause the sliding block 72 to flow poorly.

[0062] Working principle of the present invention:

[0063] Refer to the instruction manual Figure 1 -Attached Figure 7 Through the overall design, the first syringe 10 and the second syringe 11 are driven by the drive motor 5 to drive the screw 71 to complete the injection of the liquid medicine, which reduces the manual injection link and makes the operation process simpler. The push injection process is constant and stable and the speed is adjustable. The push injection process is more stable, reliable and comfortable. In addition, the syringe can be switched at any time to replace two different liquid medicines for injection, which is convenient and efficient, and solves the problem of complicated and cumbersome operation of replacing liquid medicine when using a single injection device.

[0064] Refer to the instruction manual Figure 1 and attached Figure 4 By setting up the speed reduction mechanism 6, the speed reduction gear 62 greatly reduces the rotation speed of the driving motor 5, so that the liquid medicine can flow stably in the first injection cylinder 10 and the second injection cylinder 11, ensuring that the entire injection process is more stable, and solving the problem that the driving motor 5 rotates too fast and causes the liquid medicine to flow too fast;

[0065] Refer to the instruction manual Figure 7 By setting up the wiping mechanism 16, during the reciprocating movement, the wiping cotton 19 wipes and cleans the surface of the guide rail 74, effectively removing impurities and dust accumulated on the outer surface of the guide rail 74, avoiding the sliding block 72 on the guide rail 74 from sliding smoothly, ensuring the smooth movement of the sliding block 72, and solving the problem of impurities accumulated on the guide rail 74 causing the sliding block 72 to flow poorly.
