The recess allows for accurate control of the injection dose during manual injection.

Description

Technical Field

[0001] This utility model relates to the field of cardiovascular medicine technology, specifically a clinical contrast injection device. Background Technology

[0002] The Department of Cardiology is responsible for the diagnosis and treatment of cardiovascular diseases. With the development of medical technology and people's increasing emphasis on health, imaging technology is widely used in health examinations, especially for important areas such as the heart. This examination method is safer and painless, and imaging technology has gradually replaced outdated methods such as surgery and sampling tests. By injecting contrast agents into the patient's affected area, clear and stable images are formed through imaging scanning equipment, allowing for an accurate assessment of the patient's actual condition and determining the direction of treatment.

[0003] During contrast-enhanced examinations, contrast agents need to be injected into the patient's body using a syringe device. Due to the high viscosity of the contrast agent, not only is accurate dosage required, but also that all the contrast agent be injected into the patient's body within a fixed time. Since the usual injection method involves manual injection using the scale on the outside of the syringe, the precision control is poor, the injection is laborious, the injection efficiency is low, and the injection quality cannot be controlled. Therefore, a clinical contrast-enhanced injection device has been proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a clinical contrast injection device that offers advantages such as precise control of the injection dose. It solves the problem that during contrast examinations, the contrast agent needs to be injected into the patient's body via a pusher device. Due to the high viscosity of the contrast agent, not only is accurate dosage required, but the entire contrast agent must also be injected into the patient's body within a fixed time. Traditional injection methods involve manual injection using external scales on the pusher, which results in poor precision control, laborious injection, low efficiency, and an inability to control injection quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clinical contrast injection device, comprising a base plate, wherein a limiting structure is provided on the top of the base plate, and an adjustment structure is provided on the top of the limiting structure;

[0006] The limiting structure includes a screw, the screw is rotatably installed inside the base plate, the screw is threadedly connected to a limiting rod, a support plate is fixedly installed on the top of the base plate, a limiting plate is fixedly installed on the top of the base plate, an injection cylinder is movably installed on the top of the support plate, and a piston rod is movably installed inside the injection cylinder.

[0007] The adjustment structure includes a fixed cylinder, a fixed cylinder fixedly installed on the top of the limiting plate, a movable cylinder sleeved on the outside of the fixed cylinder, a rotating shaft rotatably installed inside the movable cylinder, a handle fixedly installed on the outside of the rotating shaft, a sliding groove formed on the outside of the rotating shaft, a recess formed inside the sliding groove, a slider fixedly installed inside the fixed cylinder, a sliding plate movably installed inside the slider, a locking block fixedly installed on the outside of the sliding plate, a pull rod fixedly installed on the outside of the sliding plate, and a spring sleeved on the outside of the pull rod.

[0008] Furthermore, the top of the limiting rod penetrates through the bottom plate and is close to the injection cylinder, while the bottom of the injection cylinder is in contact with the support plate.

[0009] Furthermore, the left side of the syringe is fitted with the limiting plate, and the movable cylinder is fitted with the syringe.

[0010] Furthermore, the slider and the groove are slidably connected, and the slide plate is slidably connected to the inner wall of the slider.

[0011] Furthermore, the locking block passes through the slider and engages with the groove, and the pull rod passes through the fixed cylinder and extends to the outside of the fixed cylinder.

[0012] Furthermore, the spring is located inside the slider, and the spring is fixedly connected to the slide plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This clinical contrast injection device uses a screw to fix the syringe via a limiting rod. Turning the handle moves the rotating shaft, slider, groove, locking block, and recess. When the rotating shaft completes one revolution, the piston rod is pushed downwards by one milliliter. Pulling the lever retracts the locking block into the slider. Continuing to rotate the rotating shaft releases the lever, allowing the slider to continue sliding within the groove. The recess allows for precise control of the injection dose during manual injection, improving injection efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A clinical contrast injection device in this embodiment includes a base plate 1, a limiting structure 2 is provided on the top of the base plate 1, and an adjustment structure 3 is provided on the top of the limiting structure 2.

[0022] The limiting structure 2 includes a screw 201, which is rotatably mounted inside the base plate 1. A limiting rod 202 is threadedly connected to the outside of the screw 201. A support plate 203 is fixedly mounted on the top of the base plate 1. A limiting plate 204 is fixedly mounted on the top of the base plate 1. An injection cylinder 205 is movably mounted on the top of the support plate 203. A piston rod 206 is movably mounted inside the injection cylinder 205.

[0023] The adjusting structure 3 includes a fixed cylinder 301, a fixed cylinder 301 fixedly installed on the top of the limiting plate 204, a movable cylinder 302 sleeved on the outside of the fixed cylinder 301, a rotating shaft 303 rotatably installed inside the movable cylinder 302, a handle 304 fixedly installed on the outside of the rotating shaft 303, a slide groove 305 opened on the outside of the rotating shaft 303, a groove 306 opened inside the slide groove 305, a slider 307 fixedly installed inside the fixed cylinder 301, a sliding plate 308 movably installed inside the slider 307, a locking block 309 fixedly installed on the outside of the sliding plate 308, a pull rod 310 fixedly installed on the outside of the sliding plate 308, and a spring 311 sleeved on the outside of the pull rod 310.

[0024] exist Figure 2 In the middle, the top of the limiting rod 202 passes through the bottom plate 1 and is close to the injection cylinder 205. The bottom of the injection cylinder 205 is in contact with the support plate 203. The top of the support plate 203 is provided with an arc-shaped groove that is adapted to the injection cylinder 205, so that the injection cylinder 205 is not easy to shake when it is inside the support plate 203.

[0025] exist Figure 2 In the middle, the left side of the syringe 205 is in contact with the limiting plate 204, and the movable cylinder 302 is in contact with the syringe 205. When the movable cylinder 302 moves to the right, it will simultaneously drive the piston rod 206 to move to the right inside the syringe 205 and complete the injection of the contrast agent.

[0026] exist Figure 4 In the middle, the locking block 309 passes through the slider 307 and is engaged with the groove 306. The pull rod 310 passes through the fixed cylinder 301 and extends to the outside of the fixed cylinder 301. When the slider 307 slides inside the slide groove 305, the locking block 309 will be squeezed by the inner wall of the slide groove 305, and after the spring 311 is compressed, the locking block 309 will retract into the slider 307.

[0027] During implementation, follow these steps: Place the syringe 205 on top of the support plate 203, rotate the screw 201 to fix the syringe 205, rotate the handle 304, and the rotating shaft 303 will rotate, causing the slider 307 to slide inside the groove 305. When the locking block 309 contacts the groove 306, it indicates that the rotating shaft 303 has rotated one revolution, and at the same time, the piston rod 206 will be pushed down by one milliliter. The groove 306 allows for accurate control of the injection dose when manually injecting the syringe 205, and also improves the injection efficiency.

[0028] In summary, this clinical contrast injection device involves placing the syringe 205 on top of the support plate 203. Rotating the screw 201 moves the limiting rod 202, simultaneously bringing the syringe 205 into contact with the movable cylinder 302 and fixing the syringe 205 in place. Rotating the handle 304 causes the rotating shaft 303 to rotate, allowing the slider 307 to slide within the groove 305. When the locking block 309 contacts the groove 306, it indicates that the rotating shaft 303 has rotated one revolution. Simultaneously, the piston rod 206 is pushed downwards by one milliliter. Pulling the lever 310 retracts the locking block 309 into the slider 307. Continuing to rotate the rotating shaft 303 releases the lever 310. 0. The slider 307 will continue to slide inside the groove 305. The groove 306 allows for accurate control of the injection dose when manually pushing the syringe 205, and also improves the injection efficiency. This solves the problem that when performing contrast examinations, the contrast agent needs to be injected into the patient's body through a pusher device. Due to the high viscosity of the contrast agent, not only is accurate dosage required, but also all the contrast agent needs to be pushed into the patient's body within a fixed time. Since the usual injection method is to manually push the contrast agent with the scale on the outside of the pusher, the accuracy control is poor, the injection is laborious, the injection efficiency is low, and the injection quality cannot be controlled.
