Abstract
Description
Technical Field
[0001] This invention relates to the field of contrast agent heating, and more particularly to a contrast agent heater for cardiovascular interventional surgery. Background Technology
[0002] Contrast agents are chemical products injected into the human body to enhance the imaging effect. Examples include iodine preparations and barium sulfate commonly used in X-ray examinations. In cardiovascular angiography, they are mostly used via intravenous injection. However, in cold seasons, when low-temperature contrast agents are injected into the body, they flow with the bloodstream, which can easily cause discomfort such as vascular irritation and chills in patients, affecting the diagnostic and treatment experience and process. Therefore, there is an urgent need for specialized heating equipment to solve this problem.
[0003] Current contrast agent heating methods have several drawbacks: First, they suffer from poor heating uniformity, often involving simple heating of a single container, which can easily lead to localized overheating or insufficient heating, potentially damaging the physicochemical properties of the contrast agent and interfering with image display. Second, they are prone to causing contrast agent stratification; under static heating conditions, the components easily separate, resulting in uneven concentrations and affecting diagnostic accuracy. Third, they have low heating efficiency and lack heat preservation capabilities; most methods can only heat a single container, failing to meet the clinical need for simultaneous use of multiple doses. Furthermore, there are no heat preservation measures after heating, leading to a rapid temperature drop and requiring repeated heating, significantly increasing the workload of medical staff and failing to fundamentally improve patient injection discomfort. Therefore, we propose a contrast agent warmer for cardiovascular interventional surgery. Summary of the Invention
[0004] Purpose of the Invention: The purpose of this invention is to provide a contrast agent warmer for cardiovascular interventional surgery, solving the problems of poor heating uniformity, easy local overheating or insufficient heating in existing contrast agent heating methods, which can damage the physicochemical properties of the contrast agent and interfere with the imaging effect. It also avoids the layering and uneven concentration of contrast agent components caused by static heating, ensuring the accuracy of diagnosis and treatment. Another purpose of this invention is to provide a contrast agent warmer with high heating efficiency, continuous heat preservation function, and the ability to heat multiple doses simultaneously, meeting the clinical need for simultaneous use of multiple contrast agents, avoiding repeated heating due to rapid temperature drop after heating, reducing the workload of medical staff, fundamentally improving the discomfort such as vascular stimulation and chills caused by low-temperature contrast agent injection, enhancing the patient's treatment experience, and ensuring the smooth conduct of cardiovascular interventional surgery.
[0005] Technical solution: A contrast agent warmer for cardiovascular interventional surgery includes a base plate, a heating water tank is fixedly connected to the upper surface of the base plate, two heat preservation cylinders are provided on the top of the heating water tank, and a placement tray is provided inside the heat preservation cylinder; A circulation pump is installed on the upper surface of the base plate and to the right of the heating water tank. The input end of the circulation pump is fixedly connected to the interior of the heating water tank, and the output end of the circulation pump is fixedly connected to a three-way solenoid valve. The front end and the rear end of the output end of the three-way solenoid valve are both fixedly connected to a circulation pipe. The top end of the circulation pipe is located inside the insulation cylinder and is fixedly connected to a spiral tube. The inner side of the spiral tube is in contact with the outer side of the placement plate. The end of the spiral tube away from the circulation pipe is fixedly connected to a circulation pipe two. The end of the circulation pipe two away from the spiral tube passes through the interior of the insulation cylinder and is fixedly connected to the top left of the heating water tank. The bottom of the insulation cylinder is fixedly connected to the heating water tank by multiple support legs.
[0006] Furthermore, the lower surface of the base plate is fixedly connected with multiple casters.
[0007] Furthermore, two hand-held push rods are fixedly connected to the upper surface of the base plate and to the left of the heating water tank, and a sponge sleeve is fitted on the upper outer wall of the hand-held push rods.
[0008] Furthermore, multiple electric heating tubes are fixedly installed inside the heating water tank.
[0009] Furthermore, an intelligent controller is fixedly installed on the front surface of the heating water tank.
[0010] Furthermore, the upper surface of the placement tray is provided with multiple placement holes.
[0011] Furthermore, a cylinder is fixedly connected to the lower surface of the placement tray, with the bottom end of the cylinder extending to the bottom of the insulation cylinder. A spring is fixedly connected between the placement tray and the insulation cylinder, located on the outer side of the cylinder. A spiral groove is formed on the outer wall of the cylinder, and a fixing column is movably installed on the inner side of the spiral groove.

[0014] Beneficial effects: This device can heat the contrast agent to a suitable temperature, avoiding discomfort such as vascular irritation and chills caused by injecting low-temperature contrast agents into the human body, thus fundamentally improving the patient's comfort during diagnosis and treatment; at the same time, through stable heating effect and uniform contrast agent concentration, it provides a guarantee for the smooth performance of cardiovascular interventional surgery and improves the quality of diagnosis and treatment. This device heats water through an electric heating element in a water tank, and then uses a circulating pump to deliver the hot water to a spiral tube. The spiral tube fits tightly with the placement plate to achieve uniform heat exchange. At the same time, the motor, cam, cylinder and other components drive the placement plate to rotate slowly back and forth and vibrate up and down, so that the contrast agent in the placement hole can fully contact the heat.

The device can perform operations such as temperature setting, motor start-up, and three-way solenoid valve switching through an intelligent controller. It has a high degree of automation and is easy for medical staff to use quickly. The universal wheels on the underside of the base plate, together with the hand handle, can flexibly adjust the position of the device. The sponge cover improves the grip comfort and adapts to different placement needs in the operating room, enhancing the practicality of the device. Attached Figure Description

[0017] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] Example like Figures 1-5 As shown, a contrast agent warmer for cardiovascular interventional surgery is provided, including a base plate 1, a heating water tank 2 fixedly connected to the upper surface of the base plate 1, two heat preservation cylinders 3 on the top of the heating water tank 2, and a placement tray 4 inside the heat preservation cylinder 3; A circulation pump 5 is installed on the upper surface of the base plate 1 and to the right of the heating water tank 2. The input end of the circulation pump 5 is fixedly connected to the interior of the heating water tank 1. The output end of the circulation pump 5 is fixedly connected to a three-way solenoid valve 6. The front end and the rear end of the output end of the three-way solenoid valve 6 are both fixedly connected to a circulation pipe 7. The top end of the circulation pipe 7 is located inside the insulation cylinder 3 and is fixedly connected to a spiral pipe 8. The inner side of the spiral pipe 8 is in contact with the outer side of the placement plate 4. The end of the spiral pipe 8 away from the circulation pipe 7 is fixedly connected to a circulation pipe 9. The end of the circulation pipe 9 away from the spiral pipe 8 passes through the interior of the insulation cylinder 3 and is fixedly connected to the top left side of the heating water tank 2. Multiple support legs 25 are fixedly connected between the bottom of the heat preservation cylinder 3 and the heating water tank 2; Multiple electric heating tubes 13 are fixedly installed inside the heating water tank 2; A smart controller 14 is fixedly installed on the front surface of the heating water tank 2; The upper surface of the placement tray 4 has multiple placement holes 15; In use, first set a suitable heating temperature through the intelligent controller 14, then start the electric heating tube 13 inside the heating water tank 2 to heat the water in the heating water tank 2. After the water temperature reaches the set value, start the circulation pump 5. The circulation pump 5 draws the hot water from the heating water tank 2 and delivers it to the three-way solenoid valve 6. By adjusting the three-way solenoid valve 6 through the intelligent controller 14, the hot water can be selected to be delivered to the circulation pipe 7 corresponding to any one of the insulation cylinders 3. The hot water enters the spiral tube 8 through the circulation pipe 7. Utilizing the fitting structure between the spiral tube 8 and the placement tray 4, the contrast agent in the placement hole 15 on the placement tray 4 is heated evenly. The hot water after heat exchange flows back to the heating water tank 2 through the circulation pipe 9 for recycling. The two insulation cylinders 3 can be used alternately. When the contrast agent in one insulation cylinder 3 has been heated, the hot water delivery path can be switched through the three-way solenoid valve 6 to heat the contrast agent in the other insulation cylinder 3. At the same time, the heated contrast agent is kept in the original insulation cylinder 3 for insulation, meeting the needs of continuous clinical use.
[0019] like Figure 2 and Figure 6 As shown, multiple casters 10 are fixedly connected to the lower surface of the base plate 1; Two hand-held push rods 11 are fixedly connected to the upper surface of the base plate 1 and to the left of the heating water tank 2. A sponge sleeve 12 is fitted on the upper outer wall of the hand-held push rods 11. A heat preservation cover 21 is snapped onto the top of the placement tray 4, and a handle 22 is fixedly connected to the top of the heat preservation cover 21; When moving the warmer, medical staff can hold the sponge sleeve 12 on the outside of the push rod 11 and use the casters 10 on the lower surface of the base plate 1 to push the warmer. The sponge sleeve 12 can improve the grip comfort, and the casters 10 can easily adjust the position of the warmer to adapt to different placement needs in the operating room. After the contrast agent is placed into the placement hole 15 of the placement tray 4, the handle 22 can be held to lock the heat preservation cover 21 on the top of the placement tray 4 to seal and keep the contrast agent in the placement tray 4 warm, reduce heat loss, and avoid the contrast agent from cooling down quickly after heating, without the need for repeated heating.
[0020] like Figure 6 , Figure 7 and Figure 8 As shown, a cylinder 16 is fixedly connected to the lower surface of the placement tray 4. The bottom end of the cylinder 16 extends to the bottom of the insulation cylinder 3. A spring 17 is fixedly connected between the placement tray 4 and the insulation cylinder 3 and on the outside of the cylinder 16. A spiral groove 18 is provided on the outer wall of the cylinder 16. A fixing column 19 is movably installed on the inner side of the spiral groove 18. A fixing seat 20 is fixedly connected to the right end of the fixing column 19. The bottom of the fixing seat 20 is fixedly connected to the lower inner surface of the insulation cylinder 3. Motors 23 are fixedly connected to the upper surface of the heating water tank 2 and below the two heat preservation cylinders 3. Cams 24 are fixedly connected to the left end of the output shaft of the motors 23. The outer wall of the cams 24 is in contact with the bottom end of the cylinder 16. During the heating process, the motor 23 can be started by the intelligent controller 14. The motor 23 drives the cam 24 to rotate. When the cam 24 rotates, it pushes the cylinder 16 to move up and down. Since the spiral groove 18 on the outside of the cylinder 16 is in movable cooperation with the fixed column 19 on the fixed seat 20, and the cylinder 16 is sleeved with a spring 17, the cylinder 16 moves up and down and drives the placement plate 4 to rotate slowly back and forth. The rotation of the placement plate 4 can make the contrast agent in the placement hole 15 fully contact the heat released by the spiral tube 8, avoid the component stratification and uneven concentration caused by static heating of the contrast agent, and further improve the heating uniformity. The motors 23 corresponding to the two heat preservation cylinders 3 can be controlled independently. When the heat preservation cylinders 3 are used alternately, the motor 23 below the corresponding heat preservation cylinder 3 can be started to ensure that the contrast agent in each heat preservation cylinder 3 can be heated evenly and ensure the accuracy of diagnosis and treatment.
[0021] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
