Description

Technical Field

[0001] The present invention relates to the technical field of angiography, and in particular to a contrast agent preheating device. Background Art

[0002] Contrast agents are chemical products that enter human tissues or organs to enhance image observation. The density of these products is higher or lower than that of surrounding tissues, and the contrast formed is used to display images using certain instruments. Contrast agents are also one of the most commonly used drugs in interventional radiology operations, mainly used for the display of blood vessels and body cavities. There are various types of contrast agents, and most of the contrast agents currently used in interventional radiology are iodine-containing preparations.

[0003] When contrast agents are stored at room temperature, they exhibit physical and chemical properties such as high concentration and high viscosity. Contrast agents at room temperature can easily increase the patient's physical discomfort during injection, so the contrast agents need to be heated before injection. The heated contrast agents can be injected better, but existing heating equipment usually does not have an automatic stirring function, and contrast agents heated during the static process are prone to precipitation.

[0038] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0039] Please also refer to Figure 1-Figure 4 This embodiment provides a contrast agent preheating device, including a storage box 10, a surrounding plate 11, a top cover plate 12, an electric heating switch 20, an electric heating wire 21, a rotating mechanism 3, a sliding component 4, a stirring component 5 and a driving component 6.

[0040] A panel 11 is disposed within the storage box 10, dividing the storage box 10 into two separate, unconnected sections. A top cover 12 is disposed on top of the storage box 10, sealing the opening of the storage box 10. A closable entrance 121 is provided at the top of the top cover 12, communicating with the interior of the panel 11. It should be understood that the bottom surface of the top cover 12 contacts the panel 11 and the top of the storage box 10, respectively, forming two separate spaces within and outside the panel 11. A cover block is provided over the entrance 121, which can be opened and closed via an interference fit. Contrast agent can be aspirated or inserted through the entrance 121 using a syringe or other object.

[0041] The electric heating switch 20 is arranged on the top cover plate 12 and is connected to the electric heating wire 21. The electric heating wire 21 is wound around the outside of the enclosure 11. It should be understood that the electric heating switch 20 is connected to the battery and controls the power supply of the electric heating wire 21.

[0042] The rotating mechanism 3 is rotatably mounted on the top cover 12, and the sliding assembly 4 is slidably mounted on the top cover 12. The rotating mechanism 3 can drive the sliding assembly 4 to slide back and forth. The electric heating switch 20 is a touch switch, and the sliding assembly 4 can slide toward the electric heating switch 20 and continuously abut the electric heating switch 20. It should be understood that the rotation of the rotating mechanism 3 drives the sliding assembly 4 to slide toward the electric heating switch 20, and after a period of continuous abutment, it slides away from the electric heating switch 20.

[0043] In other embodiments, the rotating mechanism 3 includes a rotating shaft 31, a transmission assembly 32, and a drive block 33; the rotating shaft 31 is rotatably mounted on the top cover 12, the drive block 33 and the transmission assembly 32 are coaxially mounted on the rotating shaft 31, the transmission assembly 32 drives the stirring assembly 5 to rotate, the drive block 33 drives the sliding assembly 4 to slide back and forth, and the drive assembly 6 is connected to the rotating shaft 31.

It should be understood that the rotation of the incomplete gear can drive the annular inner rack 41 to slide back and forth, and when the annular inner rack 41 slides toward the electric heating switch 20, the extrusion plate 43 is driven to abut against the electric heating switch 20 via the connecting spring 42, and gradually compresses the connecting spring 42, and after a period of time, moves away from the electric heating switch 20, thereby achieving periodic heating and avoiding adverse effects caused by continuous heating.

[0045] The stirring assembly 5 is rotatably mounted on the top cover 12, with one end of the stirring assembly 5 positioned within the enclosure 11. The rotating mechanism 3 drives the stirring assembly 5 to rotate. Specifically, while the sliding assembly 4 abuts the electric heating switch 20, energizing the heating wire 21 to generate heat, the stirring assembly 5 rotates and stirs the contrast agent within the inner plate, achieving simultaneous stirring and heating.

[0046] The driving assembly 6 is disposed on the top cover plate 12 and can drive the rotating mechanism 3 to rotate.

[0048] In other schemes, the stirring assembly 5 includes a driven shaft 51, a driven sheave 52 and a stirring blade 53; the driven shaft 51 is rotatably passed through the top cover plate 12, the driven sheave 52 is coaxially arranged on the driven shaft 51 and is higher than the top cover plate 12, the cylindrical pin 322 can intermittently drive the driven sheave 52 to rotate, and the arc-shaped boss 323 can limit the rotation of the driven sheave 52 in the rotation gap of the driven sheave 52; a plurality of stirring blades 53 are provided, and are circumferentially arranged on the driven shaft 51, and the stirring blades 53 are arranged in the enclosure 11.

[0049] It should be understood that by periodically driving the driven groove wheel 52 to rotate through the cylindrical pin 322, and then driving the periodic rotation of the stirring blade 53, the noise generated by continuous stirring during storage can be reduced; the arc-shaped boss 323 matches the concave arc surface of the driven groove wheel 52 and can be inserted into it, and the arc-shaped boss 323 and the cylindrical pin 322 do not contact the driven groove wheel 52 at the same time.

[0050] In other schemes, a pushing component 7, a pressing component 8 and a scraper component 9 are also provided; the pushing component 7 is arranged on the rotating shaft 31, and the top of the driven shaft 51 is also axially provided with a first slide groove 511, the pressing component 8 is elastic, and can be raised and lowered in the first slide groove 511, and the pushing component 7 can drive the pressing component 8 to descend; the stirring piece 53 is also provided with a second slide groove 531 extending toward the rotating shaft 31, and the second slide groove 531 is connected to the first slide groove 511, the scraper component 9 corresponds to the second slide groove 531 one by one, and can be slidably provided in the second slide groove 531, the scraper component 9 is elastic, and the descent of the pressing component 8 can cause the scraper component 9 to slide outward. As the rotating shaft 31 rotates, the pushing assembly 7 periodically abuts and squeezes the pressing assembly 8, causing the pressing assembly 8 to descend, driving the scraper assembly 9 to slide outward, and the sliding scraper assembly 9 abuts against the inner wall of the enclosure 11, so that the driven shaft 51 rotates while scraping the inner wall of the enclosure 11, preventing the contrast agent from being deposited on the inner wall of the enclosure 11.

[0051] In other embodiments, the pushing assembly 7 includes a connecting rod 71 and a pushing block 72 ; the connecting rod 71 is radially connected to the rotating shaft 31 , and the pushing block 72 is provided on the connecting rod 71 , and the rotation of the rotating shaft 31 can cause the pressing assembly 8 to descend through the pushing block 72 .

The top of the slide rod 81 is provided with an inclined surface, and the pushing block 72 can squeeze the inclined surface of the slide rod 81 to make the slide rod 81 descend; one end of the push rod 83 is connected to the slide rod 81, and the other end is placed in the second slide groove 531. The descent of the push rod 83 can drive the scraper assembly 9 to slide outward.
