Abstract
Description
Technical Field
[0001] This application relates to the field of cardiovascular angiography, and more specifically, to a cardiovascular angiography compression device. Background Technology
[0002] Cardiovascular angiography involves rapidly injecting a contrast agent into the heart chambers or blood vessels through a cardiac catheter, allowing the heart and blood vessels to be visualized under X-ray irradiation. The visualization process is then captured on rapid radiographs, providing insights into the physiological and anatomical changes in the heart and blood vessels. It is a valuable diagnostic method for cardiovascular diseases. Cardiovascular angiography is typically performed via subcutaneous puncture of the femoral artery. After the procedure, the physician applies sustained manual pressure to the puncture site to stop bleeding.
[0003] CN215018289U discloses a cardiovascular angiography compression device. The device is equipped with a servo motor. The rotation of the servo motor can drive the connecting rod, the driving gear, the driven gear and the threaded tube to rotate. With the threaded connection between the threaded tube and the threaded rod, the threaded rod can be raised and lowered inside the threaded tube. The driving gear and the driven gear are set perpendicularly to change the transmission direction. Finally, it can drive the compression plate to rise and fall to perform compression operation on the human body.
[0004] However, the above method has some drawbacks: the pressure on the puncture site is applied in a straight up-down manner. Different patients have different puncture sites and body shapes, and the curved pressure plate is difficult to apply pressure to the puncture site, which has significant limitations. Summary of the Invention
[0005] To overcome the shortcomings of the existing methods, this application provides a cardiovascular angiography compression device that can solve the problem that the compression of the puncture site is done in a straight up-down manner, which is difficult for different patients with different puncture sites and body shapes, and the arc-shaped compression plate is difficult to adapt to the puncture site, resulting in significant limitations.
[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0007] A cardiovascular angiography compression device includes a fixation component and a compression component.
[0008] The fixing assembly includes a clamp, a first electric push rod, and a second electric push rod. The first electric push rod is disposed on the top of the clamp, and the second electric push rod is horizontally disposed on the top of the first electric push rod.
[0009] The pressing assembly includes a fixed plate, a locking element, a fixed tube, a slide rod, a pressing plate, an elastic element, an arc-shaped retaining plate, and a limiting rod. The fixed plate is disposed at the end of the second electric push rod, the fixed tube is rotatably disposed on one side of the fixed plate, the locking element is disposed between the fixed plate and the locking element, one end of the slide rod is slidably disposed inside the fixed tube, the pressing plate is disposed at the other end of the slide rod, the elastic element is sleeved on the outside of the fixed tube, the arc-shaped retaining plate is sleeved on the fixed tube, and the limiting rod is fixedly connected to the fixed tube.
[0010] In one specific embodiment, the locking element includes a ring and a knob, the ring being fixedly connected to the fixing tube, the knob being threaded through the fixing disc, and the knob being engaged with the ring.
[0011] In the above process, by setting a ring and a knob, the fixed tube is rotated together with the ring, and then locked with the knob.
[0012] In one specific implementation, the ring has multiple positioning holes, and the knob is adapted to the positioning holes.
[0013] In the above process, multiple positioning holes are opened, and the knob is screwed into the positioning holes to achieve stable locking.
[0014] In one specific implementation, the slide bar has a guide plane, and the pressing plate is arc-shaped.
[0015] In the above implementation process, a guide plane is created to restrict the rotation of the slide rod, and the guide slide rod moves linearly.
[0016] In one specific implementation, the elastic element includes a spring and a sliding ring, the spring being sleeved on the outside of the fixed tube and the sliding rod, and the sliding ring being slidably sleeved on the outside of the fixed tube and abutting against the spring.
[0017] In the above process, by setting up a spring and a sliding ring, the elasticity of the spring is used to push the pressing plate to press on the puncture site, which can reduce the pressure.
[0018] In one specific implementation, the arc-shaped plate has multiple adjustment slots, and the limiting rod abuts against the adjustment slots.
[0019] In the above implementation process, by opening multiple adjustment slots, the adjustment can be made after pressing the puncture site with the adjustment slots at different positions, so as to avoid pressing too hard or too lightly.
[0020] In one specific implementation, the fixture includes a C-shaped plate, a threaded rod, and a clamping plate, wherein the threaded rod is threaded through the C-shaped plate, and the clamping plate is movably mounted on the top end of the threaded rod.
[0021] In the above implementation process, by setting up a C-shaped plate, a threaded rod, and a clamping plate, the C-shaped plate is fitted onto the bed board, and the threaded rod is turned to drive the clamping plate to clamp onto the bed board.
[0022] In one specific implementation, the clamping plate is located inside the C-shaped plate, and the clamping plate and the inner wall of the C-shaped plate are fitted with a clearance.
[0023] In the above implementation process, by setting a C-shaped plate and a clamping plate with clearance fit, the rotation of the clamping plate is restricted, and the linear movement of the guide is restricted.
[0024] The advantages of this application embodiment are: by setting a clamp, a first electric push rod and a second electric push rod, the whole assembly can be easily clamped and fixed to the bed board; by setting a fixing plate, a locking member, a fixing tube, a sliding rod, a pressing plate, an elastic member, an arc-shaped clamping plate and a limiting rod, the angle of the fixing tube can be adjusted and then locked with the locking member, which can adapt to pressing the puncture site at different positions. At the same time, the pressing force can be adjusted along the direction of the sliding rod in the later stage to avoid pressing too hard or too lightly. Attached Figure Description

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.
[0031] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0032] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.
[0033] Please see Figures 1-4 This application provides a cardiovascular angiography compression device including a fixation component 100 and a compression component 200.
[0034] Please see Figure 1 and 2 The fixing component 100 includes a clamp 110, a first electric push rod 120 and a second electric push rod 130. The first electric push rod 120 is disposed on the top of the clamp 110 and the second electric push rod 130 is horizontally disposed on the top of the first electric push rod 120.
[0035] The fixture 110 includes a C-shaped plate 111, a threaded rod 112, and a clamping plate 113. The threaded rod 112 is threaded through the C-shaped plate 111, and the clamping plate 113 is movably installed on the top of the threaded rod 112. By setting the C-shaped plate 111, the threaded rod 112, and the clamping plate 113, the C-shaped plate 111 is fitted onto the bed board, and turning the threaded rod 112 causes the clamping plate 113 to be clamped onto the bed board.
[0036] In one specific implementation, the clamping plate 113 is located inside the C-shaped plate 111, and the clamping plate 113 and the inner wall of the C-shaped plate 111 are in clearance fit. By setting the C-shaped plate 111 and the clamping plate 113 in clearance fit, the rotation of the clamping plate 113 is restricted, and its linear movement is restricted.
[0037] Please see Figure 1 , 2 3 and 4, the pressing assembly 200 includes a fixed plate 210, a locking element 220, a fixed tube 230, a slide rod 240, a pressing plate 250, an elastic element 260, an arc-shaped clamping plate 270, and a limiting rod 280. The fixed plate 210 is disposed at the end of the second electric push rod 130. The fixed tube 230 is rotatably disposed on one side of the fixed plate 210. The locking element 220 is disposed between the fixed plate 210 and the locking element 220. One end of the slide rod 240 is slidably disposed inside the fixed tube 230. The pressing plate 250 is disposed at the other end of the slide rod 240. The elastic element 260 is sleeved on the outside of the fixed tube 230. The arc-shaped clamping plate 270 is sleeved on the fixed tube 230. The limiting rod 280 is fixedly connected to the fixed tube 230.
[0038] The locking component 220 includes a ring 221 and a knob 222. The ring 221 is fixedly connected to the fixing tube 230, and the knob 222 is threaded through the fixing plate 210 and is engaged with the ring 221. By setting the ring 221 and the knob 222, the fixing tube 230 is rotated together with the ring 221, and then the knob 222 is used to lock it.
[0039] Specifically, the ring 221 has multiple positioning holes 2211, and the knob 222 is adapted to the positioning holes 2211. By opening multiple positioning holes 2211, the knob 222 is screwed into the positioning holes 2211 to achieve stable locking.
[0040] In this embodiment, the slide bar 240 has a guide plane 241 and the pressing plate 250 is arc-shaped. By opening the guide plane 241, the rotation of the slide bar 240 is restricted and the slide bar 240 is guided to move linearly.
[0041] The elastic element 260 includes a spring 261 and a sliding ring 262. The spring 261 is sleeved on the outside of the fixed tube 230 and the slide rod 240. The sliding ring 262 is slidably sleeved on the outside of the fixed tube 230 and abuts against the spring 261. By setting the spring 261 and the sliding ring 262, the spring 261 pushes the pressing plate 250 to press the puncture site, thereby reducing the pressure.
[0042] It should be noted that the arc-shaped card plate 270 has multiple adjustment slots 271, and the limiting rod 280 abuts against the adjustment slots 271. By having multiple adjustment slots 271, the adjustment slots 271 at different positions can be adjusted after pressing the puncture site to avoid pressing too hard or too lightly.
[0043] The working principle of this cardiovascular angiography compression device is as follows: First, place the C-shaped plate 111 onto the bed board. Tighten the threaded rod 112 to clamp the clamping plate 113 onto the patient's bed board. Then, activate the first electric push rod 120 and the second electric push rod 130 to adjust the compression plate 250 closer to the patient's puncture site. Next, according to the patient's puncture site, first unscrew the knob 222, rotate the fixing tube 230 and the ring 221 relative to the fixing plate 210, and adjust the angle of the bottom compression plate 250 towards the patient's puncture site. Finally, screw the knob 222 back into the bottom positioning hole 2211. Then push the pressure plate 250 to compress the spring 261, move the patient on the bed to the position where the pressure plate 250 is pressed, and then release the pressure plate 250 so that the pressure plate 250 presses on the patient's puncture site, reducing manual fatigue. At the same time, the pressure can be adjusted according to whether the pressure is too large or too small. When adjusting, hold the pressure plate 250 with one hand and press the sliding ring 262 with the other hand and rotate it. Adjust the different adjustment slots 271 of the arc-shaped locking plate 270 to align with the limiting rod 280 and then release it. This allows the pressure intensity to be adjusted along the direction of the sliding rod 240 in the later stage, avoiding pressing too hard or too lightly.
[0044] It should be noted that the specific model and specifications of the first electric actuator 120 and the second electric actuator 130 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0045] The power supply and operating principle of the first electric actuator 120 and the second electric actuator 130 are clear to those skilled in the art and will not be described in detail here.
[0046] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
