[0002] Contrast agents are chemical products that enhance the visual appearance of human images. They are injected into the body via peripheral veins during imaging examinations such as MRI and enhanced CT scans. However, with current conditions and equipment, contrast agents are primarily administered manually. During this process, the doctor administering the contrast agent is exposed to X-rays, which can lead to radiation exposure for the doctor over a long period. Furthermore, manual injection lacks precision and cannot provide real-time monitoring of the injection speed. Utility Model Content

[0003] The purpose of this invention is to provide an imaging device that addresses the problems of radiation exposure to doctors and the inability to display injection speed in existing technologies involving manual injection.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The propulsion assembly and the display assembly are mounted on the support. One end of the interventional catheter is connected to the propulsion assembly, and the other end of the interventional catheter extends into the cavity to be imaged. The sensing assembly is mounted on the propulsion assembly and is electrically connected to the display assembly. In use, the propulsion assembly controls the interventional catheter to enter the cavity to be imaged, and the sensing assembly monitors the propulsion speed of the propulsion assembly and transmits the data to the display assembly for display.

[0006] In some embodiments, the propulsion assembly includes an injection element and a propulsion element connected to one end of the injection element, the other end of the injection element being connected to the interventional catheter, and the sensing element being located at the end of the injection element away from the interventional catheter.

Grooves are provided on the outer periphery of both the first turntable and the second turntable.

[0011] In some embodiments, the first turntable and the second turntable abut each other, and the grooves on the first turntable and the second turntable form a receiving cavity for the interventional catheter to slide.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] In the description of this utility model, it should be clarified that the terms "vertical," "lateral," "longitudinal," "front," "rear," "left," "right," "up," "down," and "horizontal," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are merely for the convenience of describing this utility model. They do not imply that the device or element referred to must have a specific orientation or position, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] This utility model provides an imaging device, such as Figure 1 As shown, the device includes an interventional catheter 1, a propulsion assembly 2, a sensing assembly 3, a display assembly 4, and a support 5. The propulsion assembly 2 and the display assembly 4 are mounted on the support 5. One end of the interventional catheter 1 is connected to the propulsion assembly 2, and the other end of the interventional catheter 1 extends into the cavity to be imaged. The propulsion assembly 2 is equipped with the sensing assembly 3, which is electrically connected to the display assembly 4. In use, the propulsion assembly 2 controls the interventional catheter 1 to enter the cavity to be imaged, and the sensing assembly 3 monitors the propulsion speed of the propulsion assembly 2 and transmits the data to the display assembly 4 for display.

[0023] With the above scheme, when medical staff use the angiography device, one end of the interventional catheter 1 is connected to the propulsion component 2, and the other end of the interventional catheter 1 is inserted into the cavity to be angiographically examined. The propulsion component 2 controls the interventional catheter 1 to enter the cavity to be angiographically examined. The sensing component 3 monitors the propulsion speed of the propulsion component 2 and transmits it to the display component 4 for display. In this way, when medical staff use the device, by setting the length of the interventional catheter 1, when the patient needs to inject contrast agent, medical staff can remotely control the propulsion component 2 to inject the contrast agent. Moreover, medical staff can display the injection speed and injection volume in real time through the display component 4.

[0024] Furthermore, the sensing component 3 can be configured as a pressure sensor or other components capable of displaying pressure and flow rate.

[0025] In the specific implementation process of this embodiment, such as Figure 1 As shown, the propulsion assembly 2 includes an injection element 21 and a propulsion element 22 connected to one end of the injection element 21. The other end of the injection element 21 is connected to the interventional catheter 1. The sensing component 3 is located at the end of the injection element 21 away from the interventional catheter 1.

[0026] More specifically, the injection component 21 can be a syringe with the liquid outlet and liquid inlet being the same end. When a contrast agent needs to be injected into the patient, the syringe draws in the contrast agent through an external contrast agent storage bottle, and then connects the syringe to the interventional catheter 1. At this time, the syringe is filled with contrast agent. After being connected to the interventional catheter 1, the liquid inlet becomes the liquid outlet. The piston rod end of the syringe is connected to the propulsion component 22. The propulsion component 22 can be any one of an electric push rod, an electro-hydraulic push rod, or a hydraulic rod, or a device that can achieve horizontal pushing function.

[0027] In the specific implementation process of this embodiment, such as Figure 1 As shown, the propulsion assembly 2 also includes a fixing member 23, the injection member 21 is disposed on the fixing member 23, and the fixing member 23 is disposed on the bracket 5.

[0028] More specifically, the propulsion component 2 also includes a fixing member 23, which is mounted on the bracket 5. There may be two or more fixing members 23, which are respectively located at both ends of the injection component 21.

[0029] In the specific implementation process of this embodiment, such as Figure 1 As shown, the imaging device also includes a retraction assembly 6, which includes a first rotating member 61, a second rotating member 62, and a driving member 63. The interventional catheter 1 is disposed between the first rotating member 61 and the second rotating member 62, and the first rotating member 61 is connected to the driving member 62.

[0030] More specifically, the imaging device also includes a retraction component 6, which controls the insertion of the interventional catheter 1 into the cavity to be imaged. The interventional catheter 1 is located between the first rotating member 61 and the second rotating member 62. When the imaging ends, the first rotating member 61 rotates under the drive of the driving member 63, while the second rotating member 62 rotates in the opposite direction. Under the action of friction, the interventional catheter 1 can be pulled out of the imaging cavity.

[0031] Furthermore, the second rotating member 62 can also be connected to the driving member 63, thereby driving the second rotating member 62 to rotate, while the first rotating member 61 rotates in the opposite direction.

[0032] In the specific implementation process of this embodiment, such as Figure 2 As shown, the retraction assembly 6 also includes a tensioning member 64, through which the first rotating member 61 and the second rotating member 62 are connected.

[0033] More specifically, the retraction assembly 6 also includes a tensioning member 64. The first rotating member 61 and the second rotating member 62 are connected by the tensioning member 64 to prevent the gap between the first rotating member 61 and the second rotating member 62 from becoming larger due to long-term use during the removal of the interventional catheter 1, thus ensuring proper control of the removal of the interventional catheter. The tensioning member 64 ensures the tension between the first rotating member 61 and the second rotating member 62.

[0034] Furthermore, the tensioning element 64 can be a return spring or other components that provide tension.

[0035] In the specific implementation process of this embodiment, such as Figure 2 As shown, the first rotating member 61 includes a first turntable 611 and a first connecting member 612 disposed on the first turntable 611, and the second rotating member 62 includes a second turntable 621 and a second connecting member 622 disposed on the second turntable 621. Grooves 6111 are provided on the outer periphery of both the first turntable 611 and the second turntable 621.

[0036] More specifically, the interventional catheter 1 is located in the groove 6111 on the first turntable 611 and the second turntable 621. The groove 6111 ensures that the contrast agent in the interventional catheter 1 will not be squeezed and can flow smoothly in the interventional catheter 1.

[0037] In the specific implementation process of this embodiment, such as Figure 2 As shown, the first turntable 611 and the second turntable 621 abut against each other, and the grooves 6111 on the first turntable 611 and the second turntable 621 form a receiving cavity for the interventional catheter 1 to slide.

[0038] In the specific implementation process of this embodiment, such as Figure 2 and Figure 3 As shown, the first connector 612 is connected to the second connector 622 via the tensioner 64.

[0039] In the specific implementation process of this embodiment, such as Figure 2 As shown, the fixing member 23 is provided with a slot, which abuts against the outer periphery of the injection member 21.

[0040] More specifically, the fixing member 23 is provided with a slot, and the liquid outlet end and push rod end of the injection member 21 are located in the slot to prevent the injection member 21 from shaking during the injection of contrast agent.

[0041] In the specific implementation process of this embodiment, such as Figure 2 As shown, the display component 4 includes a display screen 41 and buttons 42 connected to the display screen 41.

[0042] More specifically, the display screen 41 can be set to two or more, one display screen 41 displays pressure, and another display screen 41 can display flow rate and flow volume.

[0043] The workflow provided by this embodiment of the utility model is as follows: When medical staff use the contrast device, the syringe draws in contrast agent through the external contrast agent storage bottle, and then connects the syringe to the interventional catheter 1. One end of the interventional catheter 1 is placed in the cavity to be contrasted. At this time, the syringe is filled with contrast agent. After connecting with the interventional catheter 1, the inlet end becomes the outlet end. The piston rod end of the syringe is connected to the pusher 22. The pusher 22 controls the interventional catheter 1 to enter the cavity to be contrasted. The sensing component 3 monitors the pusher speed of the pusher 2 and transmits it to the display component 4 for display. At the end of the contrast, the first rotating component 61 rotates under the drive of the drive component 63, while the second rotating component 62 rotates in the opposite direction. Under the action of friction, the interventional catheter 1 can be pulled out of the contrast cavity. The setting of the tensioning component 64 ensures the tension between the first rotating component 61 and the second rotating component 62. Furthermore, when a patient needs contrast agent injection, medical staff can remotely control the propulsion component 2 to inject the contrast agent, and the medical staff can display the injection speed and injection volume in real time through the display component 4.

[0044] In summary, when medical personnel use this imaging device, one end of the interventional catheter 1 is placed in the cavity to be imaged, and the other end of the interventional catheter 1 is connected to the advancement component 2. The advancement component 2 controls the interventional catheter 1 to enter the cavity to be imaged. The sensing component 3 monitors the advancement speed of the advancement component 2 and transmits it to the display component 4 for display. Thus, when using this device, medical personnel can set the length of the interventional catheter 1, and when the patient needs to inject contrast agent, the medical personnel can remotely control the advancement component 2 to inject the contrast agent. Furthermore, the medical personnel can display the injection speed and injection volume in real time through the display component 4.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
