Abstract
Description
Technical Field
[0001] This invention relates to the field of cardiovascular angiography equipment technology, specifically to a post-cardiovascular angiography compression support device. Background Technology
[0002] Coronary angiography is a minimally invasive interventional procedure performed through peripheral arteries. The radial artery of the right hand is typically chosen for puncture. After puncture, a catheter is advanced along the artery to the root of the aorta, reaching the coronary sinus. Contrast agent is then injected into the coronary artery, allowing visualization of its morphology. This enables observation of coronary artery stenosis and its degree, determining whether further interventional treatment is needed. Radial artery puncture is required during coronary angiography, and compression hemostasis should be performed for 6 hours post-procedure. Due to the high arterial pressure, the right hand should be kept as still as possible during hemostasis, requiring wrist compression for better hemostasis. Uncontrolled movement may lead to oozing. Currently, suspension mechanisms are commonly used to suspend the arm upwards, but prolonged use can easily cause numbness and poor hemostasis. Therefore, we propose a post-angiography compression support device for cardiovascular use to address these issues. Summary of the Invention
[0003] The purpose of this invention is to provide a postoperative compression support device for cardiovascular angiography to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a post-angiography compression support device for cardiovascular applications, comprising a lifting support frame and a tray that moves vertically along the axis of the lifting support frame. The lifting support frame includes a top frame and a bottom frame distributed vertically, and the top frame and bottom frame are respectively provided with an upper through slot and a lower through slot for the tray to pass through.
[0005] A gear ring is rotatably mounted on the base frame. Four driven gears are centrally symmetrically distributed on the gear ring, and the four driven gears mesh with the gear ring simultaneously. A rotating shaft is coaxially fixedly mounted on the driven gears. The inner end of the rotating shaft is rotatably connected to the outer side of the tray through a connecting rod structure. A driving gear is also meshed on the gear ring, and the driving gear is driven by a motor.
[0006] The top frame is equipped with a sealing plate that allows the upper through slot to be opened or closed.
[0007] The tray has mounting ear plates on both sides of its top. A pressing mechanism is rotatably mounted between the two mounting ear plates. The pressing mechanism includes a mounting frame rotatably connected to the mounting ear plates. Side clamping frames are rotatably mounted on both sides of the mounting frame. A wrist clamping pad that contacts the patient's wrist is fixedly mounted at the end of the side clamping frame. A support plate is fixedly mounted on the mounting frame between the two wrist clamping pads. A hand clamping frame extending towards the center is rotatably mounted on the inner side of the side clamping frame. A hand disinfection mechanism for disinfecting the patient's fingers is movably mounted on the inner side of the mounting frame.
[0008] Preferably, the linkage structure consists of a first linkage and a second linkage that are hinged to each other, wherein the outer end of the second linkage is fixedly connected to the end of the rotating shaft, and the outer end of the first linkage is rotatably connected to the outer side of the tray.
[0009] Preferably, the top frame includes a top connecting cylinder and an end cap detachably mounted on the top connecting cylinder. The top connecting cylinder and the end cap form a circular space. The sealing plate is composed of at least four grid plates of the same shape. The same corner of any grid plate is rotatably connected to the top connecting cylinder via a connecting shaft. The other corner of the grid plate is rotatably connected to one end of an arc-shaped rod. The other end of the arc-shaped rod is rotatably connected to the inner side of a movable ring. The movable ring is rotatably mounted on the top of the top connecting cylinder. A lever is fixedly provided at the outer end of the movable ring.
[0010] Preferably, torsion springs are provided at the rotatable connection between the side clamp and the mounting frame and at the rotatable connection between the hand clamp and the side clamp. Under the action of the torsion springs, the two side clamps rotate towards the middle to clamp the patient's wrist between the two wrist clamp pads; the two hand clamps rotate towards the middle to clamp the patient's hand between the hand clamps.
[0011] Preferably, the hand disinfection mechanism includes a connecting frame that is movably mounted on a mounting bracket via a cylinder. Multiple parallel medical cotton rollers are rotatably mounted on the connecting frame via elastic rods. Disinfection chambers are provided on both sides of the medical cotton rollers. Uniformly distributed dispensing holes are opened on the outer surface of the disinfection chambers. Disinfectant is injected into the disinfection chambers. The disinfectant in the disinfection chambers is sprayed onto the medical cotton rollers by a micro pump, which facilitates the disinfection of the patient's hands.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] In this invention, the lifting support frame can be installed on one side of the hospital bed. The top frame uses a grating-structured sealing plate, allowing for flexible control of the opening and closing of the upper passage. In practice, when hand support is needed, the upper passage opens, and the tray and pressing mechanism move upwards from below the lower passage until they are above the upper passage. When hand support is no longer needed, the tray and pressing mechanism move back below the lower passage, closing the upper passage and ensuring the top of the lifting support frame is level, thus not affecting the normal use of the hospital bed.
[0014] By moving the lever, the movable ring rotates. When the movable ring rotates counterclockwise as shown in the figure, the grid plate rotates outward and opens the upper through slot; when the movable ring rotates clockwise as shown in the figure, the grid plate rotates inward and closes the upper through slot.
[0015] This invention can also automatically disinfect the patient's fingers by holding the patient's wrist between two wrist clamping pads; two hand clamping frames rotate inward to hold the patient's hand between them; multiple medical cotton rollers are elastically connected and will pop out to the sides of the fingers after encountering them, and then get into the gaps between the fingers to disinfect the patient's fingers in all directions. Excess disinfectant will fall directly into the inner plate for centralized treatment. Attached Figure Description

[0025] The technical solutions of the present invention will now be described in conjunction with the accompanying drawings and embodiments.
[0026] Please see Figure 1-6 The present invention provides a technical solution: a cardiovascular angiography postoperative compression support device, including a lifting support frame 1 and a tray 2 that moves up and down along the axis of the lifting support frame 1. The lifting support frame 1 includes a top frame 12 and a bottom frame 11 distributed vertically. The top frame 12 and the bottom frame 11 are respectively provided with an upper through groove 123 and a lower through groove 1101 for the tray 2 to pass through. The upper through groove 123 and the lower through groove 1101 have the same shape and match the shape of the tray 2.
[0027] In one embodiment of the present invention, the tray 2 is configured as a square, and a removable inner tray 201 is provided on the inner side of the tray 2.
[0028] like Figure 2 As shown, a gear ring 13 is rotatably mounted on the base frame 11. Four driven gears 14 are centrally symmetrically distributed on the gear ring 13, and all four driven gears 14 mesh with the gear ring 13 simultaneously. A rotating shaft 15 is coaxially fixedly mounted on each driven gear 14. The inner end of the rotating shaft 15 is rotatably connected to the outer side of the tray 2 via a connecting rod structure 16. A driving gear 17 is also meshed on the gear ring 13, and the driving gear 17 is driven by a motor 18. In this invention, the motor 18 drives the driving gear 17 to rotate, causing the gear ring 13 meshing with the driving gear 17 to rotate, thereby ensuring that the four driven gears 14 on the gear ring 13 can rotate along the same annular direction.
[0029] In one embodiment of the present invention, a mounting base 1501 is rotatably sleeved on the outer side of the rotating shaft 15, and the mounting base 1501 is fixedly mounted on the base frame 11.
[0030] Furthermore, the linkage structure 16 is composed of a first linkage 161 and a second linkage 162 that are hinged to each other, wherein the outer end of the second linkage 162 is fixedly connected to the end of the rotating shaft 15, and the outer end of the first linkage 161 is rotatably connected to the outer side of the tray 2.
[0031] like Figure 3As shown, the four linkage structures 16 are all folded along the same annular direction, and the four linkage structures 16 are located on the four sides of the tray 2, forming a spatial four-bar linkage structure. The degrees of freedom between each pair of linkage structures 16 restrict each other, thereby ensuring the stability of the tray 2's movement and stable support after it is raised. Among them, the second linkage 162 rotates with the rotating shaft 15, driving the first linkage 161 to rotate circumferentially about the hinge point of the first linkage 161 and the second linkage 162. At the same time, the rotation of the second linkage 162 allows the tray 2 to move from above the lifting support frame 1 to below the lifting support frame 1.
[0032] The top frame 12 is provided with a sealing plate 19 that allows the upper through groove 123 to be opened or closed. The top frame 12 includes a top connecting cylinder 121 and an end cap 122 that is detachably installed on the top connecting cylinder 121. The top connecting cylinder 121 and the end cap 122 form a circular space. The upper through groove 123 passes through both the top connecting cylinder 121 and the end cap 122. The sealing plate 19 is composed of at least four grid plates of the same shape. The same corner of any grid plate is rotatably connected to the top connecting cylinder 121 via a connecting shaft. The other corner of the grid plate is rotatably connected to one end of an arc rod 1901. The other end of the arc rod 1901 is rotatably connected to the inner side of a movable ring 124. The movable ring 124 is rotatably installed on the top of the top connecting cylinder 121. A lever 125 is fixedly installed on the outer end of the movable ring 124.
[0033] In this invention, the lifting support frame 1 can be installed on one side of the hospital bed. The top frame 12 contains a sealing plate 19 with a grating structure, which can flexibly control the opening and closing of the upper through slot 123. In practice, when hand support is needed, the upper through slot 123 is opened, and the tray 2 and the pressing mechanism 3 move upward from below the lower through slot 1101 until they are above the upper through slot 123. When hand support is not needed, the tray 2 and the pressing mechanism 3 move back below the lower through slot 1101, at which point the upper through slot 123 is closed, ensuring that the top of the lifting support frame 1 is flush and does not affect the normal use of the hospital bed.
[0034] By moving the lever 125, the movable ring 124 is driven to rotate. When the movable ring 124 moves along... Figure 4 When rotated counterclockwise, the grid plate rotates outward, opening the upper through slot 123; when the movable ring 124 moves along... Figure 4 When rotated clockwise, the grid plate rotates inward, closing the upper through slot 123.
[0035] The tray 2 has mounting ear plates 202 on both sides of the top. A pressing mechanism 3 is rotatably mounted between the two mounting ear plates 202. The pressing mechanism 3 includes a mounting frame 31 rotatably connected to the mounting ear plates 202. Side clamping frames 32 are rotatably mounted on both sides of the mounting frame 31. A wrist clamping pad 33 that contacts the patient's wrist is fixedly mounted at the end of the side clamping frame 32. A support plate 3101 is fixedly mounted on the mounting frame 31 between the two wrist clamping pads 33. A hand clamping frame 34 extending towards the middle is rotatably mounted on the inner side of the side clamping frame 32. A hand disinfection mechanism 35 for disinfecting the patient's fingers is movably mounted on the inner side of the mounting frame 31.
[0036] A torsion spring is provided at the rotatable connection between the side clamp 32 and the mounting frame 31, and at the rotatable connection between the hand clamp 34 and the side clamp 32. Under the action of the torsion spring, the two side clamps 32 rotate towards the middle to clamp the patient's wrist between the two wrist clamps 33; the two hand clamps 34 rotate towards the middle to clamp the patient's hand between the hand clamps 34.
[0037] In one embodiment of the present invention, the hand clamp 34 adopts an arc-shaped structure that matches the degree of hand bending, making it easy for the patient's hand to grip.
[0038] The hand disinfection mechanism 35 includes a connecting frame 351 that is movably mounted on a mounting frame 31 via a cylinder. Multiple parallel medical cotton rollers 352 are rotatably mounted on the connecting frame 351 via elastic rods. Disinfection chambers 353 are provided on both sides of the medical cotton rollers 352. The outer surface of the disinfection chambers 353 has uniformly distributed dispensing holes. Disinfectant is injected into the disinfection chambers 353. The disinfectant in the disinfection chambers 353 is sprayed onto the medical cotton rollers 352 by a micro pump, which facilitates the disinfection of patients' hands.
[0039] After the patient extends their finger, the cylinder drives the connecting frame 351 to move towards the finger. Because the multiple medical cotton rollers 352 are elastically connected, they will pop out to both sides of the finger after encountering it and get into the gap between the fingers, thus disinfecting the patient's finger in all directions. Excess disinfectant will fall directly into the inner plate 201 for centralized treatment.
[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
