Description

Technical Field

[0001] This utility model relates to the field of contrast agent injection technology, specifically to a contrast agent injection device for hysterosalpingography. Background Technology

[0002] Contrast agents are substances used in medical imaging examinations. They enhance image contrast, helping doctors to observe internal structures and organs more clearly. Based on imaging principles, there are contrast agents such as barium sulfate and iodine-containing contrast agents used in X-ray examinations, gadolinium-based contrast agents used in magnetic resonance imaging (MRI), and ultrasound contrast agents. Based on their physical properties, they can be classified as positive and negative contrast agents.

[0003] During hysterosalpingography (HSG), the contrast agent is usually heated due to the delicate nature of the fallopian tubes. Heating the contrast agent also improves absorption and examination efficiency. While equipment for heating contrast agents is available and widely used, it still has several shortcomings. Existing equipment lacks a circulating heating and recovery function for cooled contrast agents. This results in a situation where some parts of the contrast agent are cool while others are hot, and its overall heat retention is poor. Repeatedly heating cooled contrast agents not only consumes significant electricity but also negatively impacts their immediate use, prolonging examination time, reducing efficiency, and potentially affecting the accuracy of results due to temperature incompatibility.

The sealing and reinforcing rings 4 are concentrically arranged with the injection head 3. The side of the sealing and reinforcing ring 4 away from the injection tube 1 is arc-shaped, and the side closer to the injection tube 1 is flat. The arc-shaped surface facilitates the connection of an external catheter, while the flat surface allows for better fit and fixation, ensuring the sealing and stability of the connection between the catheter and the injection head 3.

[0027] Combined with appendix Figure 1 Appendix Figure 2Supporting skeleton, arranged below the push injection tube 1, used for fixing the push injection tube 1 and the electric push rod 2. The supporting skeleton comprises a horizontal plate 14 fixed below the push injection tube 1, and a vertical plate 15 fixed at one end of the horizontal plate 14, and the electric push rod 2 is fixed at the end of the vertical plate 15. The horizontal plate 14 and the vertical plate 15 are designed to stably fix the push injection tube 1 and the electric push rod 2. An anti-skid handle 16 is fixed below the horizontal plate 14, which is convenient for hand holding during operation. The overall structure is reasonable, which is beneficial to stable operation and handheld use of the device.

[0028] Combined with the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , the accompanying drawings Figure 4 , the storage tank 5 is fixed below the supporting skeleton and communicates with the push injection tube 1 through the extraction tube 6, and the extraction pump 7 is arranged on the extraction tube 6. The push injection head 3 and the extraction tube 6 are both provided with a stop valve 17, which can conveniently control the flow path of the contrast medium and accurately control the in and out of the contrast medium in different operation stages, thereby improving the accuracy and controllability of the push injection process.

[0029] Combined with the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , the accompanying drawings Figure 4 , the heating tank 8 is fixed below the supporting skeleton and communicates with the push injection tube 1 through the supply tube 9, and the supply pump 10 is arranged on the supply tube 9. The heating tank 8 also communicates with the storage tank 5 through the communication tube 11, and the circulation pump 12 is arranged on the communication tube 11. The side wall of the heating tank 8 is provided with a heating module 13. The heating module 13 is one of an electric heating plate, an electric heating wire and an electric heating pipe, which provides multiple selection modes. The appropriate heating mode can be selected flexibly according to actual needs, cost and other factors to meet different use scenarios.

[0030] Combined with the accompanying drawings Figure 1 , the outer walls of the push injection tube 1, the storage tank 5 and the heating tank 8 are all provided with a heat preservation structure. The heat preservation structure comprises a heat preservation coating coated on the outer walls of the push injection tube 1, the storage tank 5 and the heating tank 8, and a heat preservation shell wrapped on the outer walls of the push injection tube 1, the storage tank 5 and the heating tank 8. The heat preservation coating is one of aerogel, polyurethane and ceramic microbeads. The heat preservation shell is one of foam, vacuum heat insulation plate and stainless steel double-layer vacuum heat preservation structure. The heat preservation coating and the heat preservation shell cooperate with each other to achieve good heat preservation effect, avoid frequent heating of the contrast medium, and save energy and be convenient.

[0031] Combined with the accompanying drawings Figure 1 , the accompanying drawings Figure 2Below the horizontal plate 14, near the anti-slip grip 16, is a resilient push switch 18 for controlling the electric push rod 2. A support frame 19 is fixedly installed below the horizontal plate 14 to hold the resilient push switch 18. The resilient push switch 18's placement near the anti-slip grip 16 facilitates control of the electric push rod 2 for contrast agent injection. Below the horizontal plate 14, near the vertical plate 15, is a wiring port 20 for connecting to an external power source, ensuring stable power supply to the device. The vertical plate 15 has a control panel 21 that controls the shut-off valve 17, extraction pump 7, supply pump 10, circulation pump 12, and heating module 13. The control panel 21 centrally controls multiple components, facilitating the injection and heating of the contrast agent, resulting in centralized and efficient control.

[0032] Combined with appendix Figure 1 Appendix Figure 2 The storage tank 5 and the heating tank 8 are both provided with cleaning ports on their side walls. The storage tank 5 is also provided with a liquid inlet on its side wall. Both the liquid inlet and the cleaning port are provided with sealing plugs 22. The liquid inlet and the cleaning port facilitate the replenishment of contrast agent and the cleaning of the storage tank 5 and the heating tank 8, respectively. The sealing plugs 22 can ensure the sealing of the device during use.

[0033] The specific implementation method of this utility model is as follows: First, open the sealing plug at the liquid inlet on the side wall of the storage tank 5, and add sufficient contrast agent into the storage tank 5 through the liquid inlet. After adding, tighten the sealing plug 22 to ensure the airtightness of the device.

[0034] Next, the external contrast agent injection catheter is tightly fitted onto the injection head 3. The sealing and reinforcing ring 4 on the outside of the injection head 3 can ensure the sealing and stability of the connection.

[0035] Then, the device is connected to an external power source through the wiring port 20 below the horizontal plate 14 to power each component.

[0036] Then, turn on the circulation pump 12 to pump the contrast agent in the storage tank 5 into the heating tank 8. According to actual needs, use the control panel 21 on the vertical plate 15 to start the heating module 13 to heat the contrast agent in the heating tank 8, and turn on the supply pump 10 to deliver the contrast agent heated to the appropriate temperature into the injection tube 1.

[0037] When preparing to inject the contrast agent, the shut-off valve 17 on the injection head 3 is opened and the shut-off valve 17 on the extraction tube 6 is closed by controlling the control panel 21. The elastic press switch 18 is pressed continuously to control the electric push rod 2. The electric push rod 2 pushes the piston in the injection tube 1 to move, and the contrast agent is injected into the uterus and fallopian tubes through the injection head 3 and the contrast agent injection catheter. This completes the contrast agent injection operation for hysterosalpingography. After the injection is completed, the elastic press switch 18 is released, and it automatically resets, causing the electric push rod 2 to contract. The piston in the injection tube 1 is reset, which facilitates the next injection operation.

[0038] After the completion of a bolus injection, if the bolus injection operation needs to be continued in a short time, the remaining contrast agent can be temporarily stored in the bolus injection tube 1, and the heat preservation coating and the heat preservation shell can heat the contrast agent; if the contrast agent needs to be injected after waiting for a period of time, the stop valve 17 on the bolus injection head 3 can be closed, the stop valve 17 on the extraction tube 6 can be opened, the extraction pump 7 can be opened, and the contrast agent in the bolus injection tube 1 can be pushed into the storage tank 5 for storage. The sealing plug 22 at the cleaning port can be opened regularly, the contrast agent can be discharged, and the inside of the storage tank 5 and the heating tank 8 can be cleaned.
