Abstract

This invention provides a transport assistance device for cardiology nursing, belonging to the field of medical equipment technology. It includes a transport component comprising four support rods, with a horizontal plate fixedly connected to the top of each rod and casters mounted on the bottom. A top plate is mounted above the horizontal plate. A scissor-type lifting mechanism driven by a motor and lead screw enables precise adjustment of the transport platform height, directly resolving the safety risks caused by the height difference between the bed and the trolley. By using a motor-driven lead screw to move the sliding frame and a scissor-type lifting mechanism composed of interlocking hinged plates, the height of the top plate and extension plate can be steplessly adjusted to precisely match the height of the bed.

Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a transport auxiliary device used in cardiology nursing. Background Technology

[0002] In cardiology clinical nursing, moving patients between their beds and transport trolleys for examinations, surgeries, or transfers is a frequent procedure. However, a significant inherent height difference exists between standard hospital beds and transport trolleys, posing a major technical obstacle to safe patient transport. Currently, the standard practice to overcome this obstacle involves multiple medical staff working together to manually lift the patient from the bed to the trolley.

[0003] The height difference between the hospital bed and the transport trolley directly leads to the complexity and instability of the transport process. Even with multiple people working together, it is difficult to ensure that the lifting process is completely horizontal and synchronized, which can easily cause the patient to sway or twist. For critically ill patients in cardiology departments, such as those who are post-operatively or have heart failure, this poses a risk of inducing circulatory fluctuations, worsening their condition, or even causing accidents. Secondly, this highly manual transport mode requires at least 2-3 medical staff to be involved simultaneously. This not only consumes time in organization and coordination and reduces transport efficiency, but also places a huge physical burden on medical staff and increases the risk of occupational injuries such as lumbar strain. Summary of the Invention

[0004] The purpose of this invention is to provide a transport assist device for use in cardiology nursing, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A transport assist device for cardiology nursing includes a transport component comprising four support rods.

Two support plates are fixedly connected to the top left side of the horizontal plate, and a lead screw is rotatably connected between the two support plates. A motor for driving the lead screw to rotate is fixedly connected to the surface of the support plate near the left end of the horizontal plate. The upper end of the sliding frame is threaded onto the outside of the lead screw.

[0010] In a preferred embodiment of the present invention, two support plates near the left end of the horizontal plate are fixedly connected to the top of the sliding frame, two support plates near the right end of the horizontal plate are fixedly connected to the top of the horizontal plate, two support plates near the left end of the top plate are fixedly connected to the sliding frame, and two support plates near the right end of the top plate are fixedly connected to the bottom surface of the top plate.

[0011] In a preferred embodiment of the present invention, the pushing assembly includes a sliding frame and an electric push rod. A movable frame is slidably connected inside the sliding groove. An electric push rod is fixedly connected to the bottom end face of the top plate. A fixed block is fixedly connected to the output end of the electric push rod. The fixed block is fixedly connected to the movable frame. Multiple toothed blocks are symmetrically fixedly connected to the inner wall of the movable frame.

[0012] As a preferred embodiment of the present invention, the extension component includes a guide groove opened at the top of the top plate, an extension plate being slidably connected inside the guide groove, and a plurality of toothed grooves being symmetrically opened on the outer side of the extension plate.

[0013] As a preferred embodiment of the present invention, the transmission assembly includes a rectangular hole. Two rectangular holes communicating with guide grooves are symmetrically opened on the outer side of the top plate. A groove is provided on the inner bottom wall of the rectangular hole. Two rotating shafts are rotatably connected between the inner bottom wall of the groove and the inner top wall of the rectangular hole. A gear is fixedly connected to the outer side of the rotating shaft. A synchronous pulley is fixedly connected to the outer side of the lower end of the rotating shaft. A synchronous belt is sleeved on the outer side of the two adjacent synchronous pulleys.

[0014] In a preferred embodiment of the present invention, the blocking assembly includes two mounting plates symmetrically and fixedly connected to the outer side of the extension plate. A rotating shaft is rotatably inserted into the middle of the mounting plate, and a protective plate is fixedly connected between the two rotating shafts. A circular plate is fixedly connected to the end of the rotating shaft away from the protective plate. A limit bolt is threaded into the circular plate. Two insertion holes are provided on the mounting plate, and the limit bolt extends into the insertion hole. A limit plate is fixedly connected to the bottom end face of the mounting plate away from the limit bolt.

[0015] As a preferred embodiment of the present invention, the rolling assembly includes a ball groove formed on the surface of the guard plate, and balls are tactilely connected inside the ball groove.

[0016] In a preferred embodiment of the present invention, the top end of the guide rod is fixedly connected to the bottom end face of the top plate, and a storage frame is fixedly connected between the four support rods.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By employing a scissor-type lifting mechanism and a motor-driven lead screw, the height of the transfer platform can be precisely adjusted, directly resolving the safety risks associated with the height difference between the hospital bed and the trolley. The scissor-type lifting mechanism, driven by a motor-driven lead screw that moves the sliding frame and utilizing interlocking hinged plates, allows for stepless adjustment of the height of the top and extension plates to precisely match the height of the hospital bed. This fundamentally eliminates instability during transport and patient body distortion caused by height differences, providing a smooth transition for postoperative patients and critically ill patients with heart failure, effectively avoiding secondary injuries such as circulatory fluctuations caused by drastic changes in body position.

[0019] 2. An automatic extension plate and rolling guard, driven by a rack and pinion mechanism, enable automated placement of the patient's pad, significantly reducing the need for manual handling. An electric actuator drives a rack-driven moving frame, with gears meshing with the teeth on the extension plate. A timing belt ensures synchronized movement of both axes, allowing the extension plate and guard to automatically and smoothly extend under the patient. The ball bearing assembly on the guard converts sliding friction into rolling friction, greatly reducing insertion resistance. This allows a single person to complete the placement operation, eliminating the need for multiple people to lift the patient, directly reducing the physical burden on medical staff and the risk of lumbar strain.

[0020] 3. A safe transport protection space is constructed through a rotatable locking guard plate and a fixed baffle, preventing patients from falling during transport. The guard plate rotation locking mechanism, consisting of a rotating shaft, insertion holes, and limiting bolts, allows for quick switching and secure locking between a horizontal protective position and a vertical storage position by inserting the limiting bolts into different holes. When erected, the guard plate, in conjunction with the fixed baffle on the front of the top plate, forms reliable guardrails on both sides of the patient, effectively preventing falls from the platform due to vehicle movement or body slippage during transport, thus ensuring safety during transport.

Detailed Implementation

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] Reference Figure 1 and Figure 7 This is the first embodiment of the present invention, which provides a transport auxiliary device for use in cardiology nursing, including a transport component comprising four support rods 10, a horizontal plate 13 fixedly connected to the top of each support rod 10, and casters 11 mounted on the bottom of each support rod 10. The casters 11 are lockable casters 11, which can be locked when needed. A top plate 19 is mounted above the horizontal plate 13, and a connecting assembly 14 is installed between the top plate 19 and the horizontal plate 13. A [missing information - likely a component or part] is mounted on the top left side of the horizontal plate 13. The drive assembly 15 has a slide groove 191 on the outer side of the top plate 19. A push assembly 20 is installed inside the slide groove 191. An extension assembly 21 is installed on the top of the top plate 19. A transmission assembly 18 is installed between the extension assembly 21 and the push assembly 20. A baffle 17 is fixedly connected to the front of the top of the top plate 19. A blocking assembly 30 is installed on the back of the extension assembly 21. A rolling assembly 31 is installed on the blocking assembly 30. A storage frame 12 is fixedly connected between the four support rods 10. The storage frame 12 is convenient for storing items.

[0036] Reference Figure 2 and Figure 3The connecting component 14 includes a sliding groove 145 and a connecting plate 141. The bottom end face of the top plate 19 is symmetrically provided with sliding grooves 145. A sliding hole 143 is provided between the two sliding grooves 145. A sliding frame 144 is slidably connected inside the two sliding grooves 145 and the sliding hole 143. The sliding frame 144 is arranged in a horizontal "I" shape. Connecting plates 141 are installed alternately between the horizontal plate 13 and the top plate 19. There are four connecting plates 141 in total. The two adjacent connecting plates 141 are hinged together. Both ends of the connecting plate 141 are rotatably connected to connecting blocks 142.

[0037] Reference Figure 2 The drive assembly 15 includes a sliding groove 155 and a support plate 152. A sliding groove 155 is formed on the top left side of the horizontal plate 13. A sliding frame 154 is slidably connected inside the sliding groove 155. The sliding frame 154 has a "mountain" shaped structure. Two support plates 152 are fixedly connected to the top left side of the horizontal plate 13. A lead screw 153 is rotatably connected between the two support plates 152. A motor 151 for driving the lead screw 153 to rotate is fixedly connected to the surface of the support plate 152 near the left end of the horizontal plate 13. The upper end of the sliding frame 154... A threaded sleeve is connected to the outside of the lead screw 153. The control motor 151 drives the lead screw 153 to rotate. The rotation of the lead screw 153 causes the sliding frame 154 to slide inside the sliding groove 155. In conjunction with the connecting plate 141, the sliding groove 145, the sliding hole 143, and the sliding frame 144, the height of the top plate 19 is adjusted, thereby adjusting the height of the extension plate 211 to match the height of the hospital bed. When adjusting the height of the top plate 19, the sliding frame 144 slides inside the sliding groove 145 and the sliding hole 143.

[0038] Reference Figure 1 , Figure 2 and Figure 3 Two support plates 152 near the left end of the horizontal plate 13 are fixedly connected to the top of the sliding frame 154, two support plates 152 near the right end of the horizontal plate 13 are fixedly connected to the top of the horizontal plate 13, two support plates 152 near the left end of the top plate 19 are fixedly connected to the sliding frame 144, and two support plates 152 near the right end of the top plate 19 are fixedly connected to the bottom surface of the top plate 19.

[0039] Reference Figure 3 , Figure 4 , Figure 5 and Figure 8The pushing assembly 20 includes a sliding frame 154 and an electric push rod 201. A movable frame 203 is slidably connected inside the slide groove 191. The electric push rod 201 is fixedly connected to the bottom end face of the top plate 19. A fixing block 202 is fixedly connected to the output end of the electric push rod 201. The fixing block 202 is fixedly connected to the movable frame 203. Multiple toothed blocks 204 are symmetrically fixedly connected to the inner wall of the movable frame 203. The extension assembly 21 includes a guide groove 213 opened at the top of the top plate 19. An extension plate is slidably connected inside the guide groove 213. 211, the outer side of the extension plate 211 is symmetrically provided with multiple toothed grooves 212; the transmission assembly 18 includes a rectangular hole 182, and the outer side of the top plate 19 is symmetrically provided with two rectangular holes 182 that communicate with the guide groove 213. The inner bottom wall of the rectangular hole 182 is provided with a groove 183, and two rotating shafts 186 are rotatably connected between the inner bottom wall of the groove 183 and the inner top wall of the rectangular hole 182. Gears 181 are fixedly connected to the outer side of the rotating shafts 186, and the gears 181 are meshed with the moving frame 203 through multiple toothed blocks 204. Gear 181 meshes with extension plate 211 through multiple tooth grooves 212. A synchronous pulley 185 is fixedly connected to the outer side of the lower end of shaft 186. A synchronous belt 184 is sleeved on the outer side of two adjacent synchronous pulleys 185. This controls the extension of electric push rod 201, thereby moving fixed block 202 and moving frame 203. The movement of moving frame 203 causes the toothed block 204 on its inner wall to move, thus driving gear 181 to rotate. The rotation of gear 181, in conjunction with the tooth grooves 212, causes extension plate 211 to move from guide groove 213. When the internal movement of the gear 181 is disengaged from the gear 181 near the guard plate 301, the gear 181 away from the guard plate 301 continues to rotate, thereby driving the rotating shaft 186, the synchronous pulley 185 and the synchronous belt 184 to rotate. This keeps the gear 181 near the guard plate 301 in a state of continuous rotation. This, in conjunction with the action of the tooth groove 212, causes the extension plate 211 to move towards the patient, thereby inserting the extension plate 211 under the patient's body without the need for manual lifting of the patient.

[0040] Reference Figure 4 , Figure 7 , Figure 9 and Figure 10The blocking assembly 30 includes two mounting plates 302 symmetrically fixedly connected to the outer side of the extension plate 211. A rotating shaft 304 is rotatably inserted into the middle of the mounting plate 302. A protective plate 301 is fixedly connected between the two rotating shafts 304. The top surface of the protective plate 301 is inclined, which facilitates the insertion of the protective plate 301 into the patient's back. A circular plate 307 is fixedly connected to the end of the rotating shaft 304 away from the protective plate 301. A limiting bolt 306 is threaded into the circular plate 307. Two insertion holes 305 are provided on the mounting plate 302. The limiting bolt 306 extends into the insertion hole 305. A limiting plate 303 is fixedly connected to the bottom surface of the mounting plate 302 away from the limiting bolt 306. Tightening the limiting bolt 306 will unscrew the limiting bolt 306 from the inside of one of the insertion holes 305, thereby rotating the protective plate 301 ninety degrees. At this time, the other insertion hole... Corresponding to the limiting bolt 306, tightening the limiting bolt 306 allows it to be inserted into another insertion hole 305, thereby limiting and fixing the protective plate 301. The limiting plate 303 supports the protective plate 301, further improving its stability during use. The rolling assembly 31 includes a ball groove 311 on the surface of the protective plate 301. A ball 312 is rolled inside the ball groove 311. When the protective plate 301 is inserted into the bottom of the patient's body, the ball 312 contacts the patient's back. The ball 312 rotates inside the ball groove 311 due to friction with the patient, making it easier to insert the protective plate 301 into the bottom of the patient's body. The baffle 17, in conjunction with the blocking assembly 30, protects the patient and prevents the patient from falling off the top plate 19 during transport.

[0041] In use, the control motor 151 drives the lead screw 153 to rotate. The rotation of the lead screw 153 causes the sliding frame 154 to slide inside the sliding groove 155. In conjunction with the connecting plate 141, the sliding groove 145, the sliding hole 143, and the sliding frame 144, the height of the top plate 19 is adjusted, thereby adjusting the height of the extension plate 211 to match the height of the hospital bed. When adjusting the height of the top plate 19, the sliding frame 144 slides inside the sliding groove 145 and the sliding hole 143.

[0042] Tighten the limiting bolt 306 to unscrew it from the inside of one of the insertion holes 305, and then rotate the guard plate 301 ninety degrees. At this time, the other insertion hole 305 corresponds to the limiting bolt 306. Tighten the limiting bolt 306 to insert it into the inside of the other insertion hole 305, thereby limiting and fixing the guard plate 301. The limiting plate 303 plays the role of supporting the guard plate 301, further improving the stability of the guard plate 301 during use.

[0043] The electric push rod 201 extends, thereby moving the fixed block 202 and the movable frame 203. The movement of the movable frame 203 causes the toothed block 204 on its inner wall to move, thereby driving the gear 181 to rotate. The rotation of the gear 181, in conjunction with the tooth groove 212, causes the extension plate 211 to move out of the guide groove 213. When the toothed block 204 on the movable frame 203 moves away from the gear 181 near the guard plate 301, the gear 181 away from the guard plate 301 continues to rotate, thereby driving the rotating shaft 186, the synchronous pulley 185, and the synchronous belt 184 to rotate. This keeps the gear 181 near the guard plate 301 in a continuously rotating state, thus engaging the tooth groove 212. The extension plate 211 and the protective plate 301 move closer to the patient. At the same time, a medical staff member stands on the opposite side and gently supports the patient's shoulder and buttocks with their hand to provide gentle resistance and ensure that the patient's body position is basically fixed, so that the extension plate can be smoothly inserted under the patient. In this way, the extension plate 211 can be inserted under the patient's body without the need for multiple people to lift the patient. When the protective plate 301 is inserted into the bottom of the patient's body, the ball bearing 312 contacts the patient's back. The ball bearing 312 rotates inside the ball bearing groove 311 under the action of friction with the patient, so that the protective plate 301 can be inserted into the bottom of the patient's body more easily and the resistance is reduced.

[0044] After the patient is transferred from the bed to the top of the extension plate 211, the electric push rod 201 is retracted to return the extension plate 211 to its original position. Then the guard plate 301 is erected to work with the baffle 17 to protect the patient's sides and prevent the patient from falling off the top plate 19.

[0045] Example 2

[0046] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a limiting component, including sleeves 22 fixedly connected to the four corners of the top of the horizontal plate 13. A guide rod 16 is slidably inserted inside the sleeve 22. The top end of the guide rod 16 is fixedly connected to the bottom end face of the top plate 19. The cooperation between the guide rod 16 and the sleeve 22 plays a guiding role in the lifting and lowering process of the top plate 19, and plays a limiting role in the lifting and lowering process of the top plate 19, further improving the stability of the top plate 19 during the lifting and lowering process.

[0047] During use, when the top plate 19 is raised or lowered, the top plate 19 drives the guide rod 16 to slide inside the sleeve 22, which improves the stability of the top plate 19 during the raising and lowering process.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
