Description

Technical Field

[0001] This utility model belongs to the field of examination bed technology, and in particular relates to an adjustable electrocardiogram examination bed. Background Technology

[0002] Electrocardiography (ECG) is a fundamental method for diagnosing heart diseases. ECG examination beds, as core supporting equipment, are widely used in various medical institutions. Traditional ECG examination beds are mostly fixed structures with non-adjustable bed height and angle, which can easily lead to lead wire entanglement and patient discomfort. This not only affects examination efficiency but may also interfere with the accuracy of test results due to improper positioning. To address these pain points, adapt to the examination needs of patients of different ages and body types, and improve operational convenience and testing accuracy, adjustable ECG examination beds have emerged.

[0003] However, existing electrocardiogram (ECG) examination beds do not allow for a slow descent of the bed board after adjustment, resulting in a rapid drop when the bed board falls back down after angle adjustment. This can not only damage the bed components due to excessive impact, but also affect the stability of the lead wire connections, indirectly interfering with the examination. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable electrocardiogram (ECG) examination bed. By incorporating a slow-descent mechanism, this invention solves the problem that existing ECG examination beds are not convenient for slowing down the bed board after adjustment, which leads to the bed board falling rapidly when it returns to its original position after angle adjustment. This can not only damage the bed components due to excessive impact force, but also easily affect the stability of the lead wire connection and indirectly interfere with the examination work.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an adjustable electrocardiogram (ECG) examination bed, comprising a bed frame and a bed frame fixedly connected to the bottom of the bed frame, and further comprising: a main body installed inside the bed frame; a slow-closing part disposed above the bed frame; a rotating part located inside the bed frame; the slow-closing part including a buffer assembly installed inside the bed frame; and a control assembly disposed inside the bed frame; the buffer assembly includes two hinged bases disposed inside the bed frame, the right side of the right hinged base being fixedly connected to the bed frame, and the left hinged base being located inside the left hinged base. A piston is hinged to the wall, and a hydraulic cylinder is hinged to the inner wall of the hinged base on the right side. The right side of the piston extends into the hydraulic cylinder. Two connecting pipes are provided inside the bed frame. The right side of the connecting pipe on the right side is connected to the hydraulic cylinder. A hydraulic cylinder is fixedly connected to the inner wall of the bed frame, and the left side of the connecting pipe on the left side is connected to the hydraulic cylinder. A damper is fixedly connected to the inner wall of the hydraulic cylinder. A piston is fixedly connected to the right side of the damper. The piston and the hydraulic cylinder are sealed together. The piston and the hydraulic cylinder are also sealed together.

[0007] Furthermore, the rotating part includes a rotating assembly installed inside the bed frame; and a transmission assembly, of which two are provided, both located inside the bed frame, and the two transmission assemblies are mirror images of each other.

[0008] Furthermore, the control component includes a valve body fixedly connected to the bottom of the bed frame. A hollow ball is disposed inside the valve body, and a rotating component is disposed inside the valve body. The left and right sides of the valve body are respectively connected to two connecting pipes. The hollow ball is a sphere with a through hole inside. The rotating component includes a rotating shaft fixedly connected to the front side of the hollow ball. The outer wall of the rotating shaft is rotatably connected to the valve body. A handle is fixedly connected to the front side of the rotating shaft. The rotating shaft and the valve body are sealed together.

[0009] Furthermore, the rotating assembly includes a second rotating shaft rotatably connected to the inner wall of the bed frame. A transmission block is fixedly connected to the front side of the second rotating shaft. A hexagonal groove is provided on the front side of the transmission block. A driving component is provided in the hexagonal groove. The front side of the second rotating shaft extends to the outside of the bed frame. The driving component includes a hexagonal bolt provided in the hexagonal groove. A handle is fixedly connected to the front side of the hexagonal bolt. The hexagonal bolt is adapted to the hexagonal groove.

[0010] Furthermore, the transmission assembly includes a transmission rack fixedly connected to the bottom of the second bed board, the inner wall of the transmission rack having a guide groove, the inner wall of the bed frame being fixedly connected to a guide rod, the outer wall of the second rotating shaft being fixedly connected to a gear, the transmission rack being an arc-shaped rack, the guide groove being adapted to the guide rod, and the gear meshing with the transmission rack.

[0011] This utility model has the following beneficial effects: 1. By setting up a slow-descent section, during use, the hollow ball of the slow-descent section rotates and connects the two connecting pipes. The hydraulic medium in hydraulic cylinder one enters hydraulic cylinder two, pushing piston two to move to one side and squeezing the damper. With the help of the damper and the hydraulic medium, the bed plate two is slowly lowered. When the hollow ball rotates and disconnects the connecting pipes, the hydraulic medium cannot flow, and the position of bed plate two is fixed. This allows bed plate two to descend slowly, preventing bed plate two from falling rapidly during adjustment and descent. It keeps the descent process of bed plate two stable and controllable, providing a stable descent guarantee for the angle adjustment of the ECG examination bed. This avoids impact damage to the bed components and avoids affecting the stability of the lead wire connection, ensuring the normal conduct of the examination. 2. By setting up a rotating part, when adjustment is needed, the hexagonal bolt of the rotating part is inserted into the hexagonal slot, and the handle is turned to drive the transmission block and the second rotating shaft to rotate. The second rotating shaft drives the gear to rotate, and the gear drives the transmission rack to move under the cooperation of the guide groove and the guide rod. The transmission rack drives the second bed board, which is fixed to it, to lift upward around the first bed board, thus completing the adjustment operation of the bed board angle. It can drive the second bed board to lift upward around the first bed board, realizing the adjustment of the angle between the second bed board and the first bed board. It can be adjusted to a suitable angle according to the actual needs of the electrocardiogram examination to meet different examination position requirements. At the same time, when it is necessary to lower it, the second handle can be removed to prevent the second handle from rotating in the opposite direction and hitting the person next to it.

[0019] The rotating part 3 includes a rotating assembly 31, which is installed inside the bed frame 101; and a transmission assembly 32, of which two are provided, both located inside the bed frame 101 and mirror-image of each other. The rotating assembly 31 includes a second rotating shaft 311 rotatably connected to the inner wall of the bed frame 101. A transmission block 312 is fixedly connected to the front side of the second rotating shaft 311. A hexagonal groove 313 is provided on the front side of the transmission block 312, and a driving component is provided in the hexagonal groove 313. The front side of the second rotating shaft 311 extends to the outside of the bed frame 101. The driving component includes a hexagonal bolt 314 disposed in the hexagonal groove 313. A second handle 315 is fixedly connected to the front side of the hexagonal bolt 314, and the hexagonal bolt 314 is adapted to the hexagonal groove 313. The transmission assembly 32 includes a fixed... A transmission rack 321 is connected to the bottom of the second bed board 105. The inner wall of the transmission rack 321 has a guide groove 322. The inner wall of the bed frame 101 is fixedly connected to a guide rod 323. The outer wall of the second rotating shaft 311 is fixedly connected to a gear 324. The transmission rack 321 is an arc-shaped rack. The guide groove 322 is adapted to the guide rod 323. The gear 324 meshes with the transmission rack 321. By setting the rotating part 3, the second bed board 105 can be driven to lift upward around the first bed board 104, realizing the adjustment of the angle between the second bed board 105 and the first bed board 104. It can be adjusted to a suitable angle according to the actual needs of the electrocardiogram examination to meet different examination position requirements. At the same time, the handle 315 can be removed when it needs to be lowered to prevent the handle 315 from rotating in the opposite direction and hitting the person next to it.

[0020] A specific application of this embodiment is as follows: During use, the mattress 103 can be tied to the first bed board 104 and the second bed board 105. When it is necessary to adjust the angle between the second bed board 105 and the first bed board 104, the first handle 224 can be rotated, causing it to rotate via the first shaft 223, thus connecting the two connecting pipes 214. Then, the second handle 315 placed inside the bed frame 102 can be removed, and the hexagonal bolt 314 can be inserted into the hexagonal slot 313. The second handle 315 can then be rotated, causing it to rotate via the hexagonal bolt 314 and the hexagonal slot 313, thus rotating the transmission block 312. When the transmission block 312 rotates, it will drive the gear 324 to rotate via the second shaft 311. When the gear 324 rotates, it will move in the guide groove 322 and the guide... The rod 323 drives the transmission rack 321 to move. Since the top of the transmission rack 321 is fixedly connected to the second bed plate 105 and the left side of the second bed plate 105 is hinged to the first bed plate 104, when the transmission rack 321 moves, the second bed plate 105 will be lifted up around the first bed plate 104 along with the transmission rack 321 to complete the adjustment. During this process, under the action of the hinge base 211, the piston 212 will move to the left from the first hydraulic cylinder 213, thereby sucking out the hydraulic medium in the second hydraulic cylinder 215 through the two connecting pipes 214. The sucked-out hydraulic medium will enter the first hydraulic cylinder 213. When the hydraulic medium in the second hydraulic cylinder 215 decreases, the piston 217 will move to the right, and the damper 216 will be stretched. After adjustment, hold handle 215 and rotate handle 224 to rotate hollow ball 222 via shaft 223, disconnecting the two connecting pipes 214. Then, release handle 215. Since the two connecting pipes 214 are disconnected, the hydraulic medium entering hydraulic cylinder 1 213 cannot flow into hydraulic cylinder 215, so bed board 2105 will not descend. When it is necessary to lower the bed board 2 105, handle 2 315 can be pulled out and placed inside the bed frame 102. Then, handle 1 224 can be turned so that it drives the hollow ball 222 to rotate through the shaft 1 223, connecting the two connecting pipes 214. At this time, the hydraulic medium in the hydraulic cylinder 1 213 will enter the hydraulic cylinder 2 215, and piston 2 217 will move to the left and squeeze the damper 216, compressing it. Due to the action of the damper 216 and the hydraulic medium, the bed board 2 105 will slowly descend, thus completing the slow descent.
