Abstract
Description
An ICU assisted transport device Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to an ICU assisted transport device. Background Technology
[0002] ICU transport equipment is a medical device used to assist medical staff in moving critically ill patients. When patients have central venous catheters, endotracheal tubes, urinary catheters, various drainage tubes, and are connected to numerous wires such as electrocardiogram monitors, disconnecting them from the bed before transferring them to the transport equipment can easily lead to problems such as bent, dislodged, or blocked tubes, affecting the patient's normal treatment and even posing a life-threatening risk. Transporting the patient while still connected to the bed better maintains the original condition of these tubes and wires, ensuring their continued normal operation during transport.
[0003] Most existing lifting equipment uses hydraulic rods or boom structures to directly lift hospital beds. This single working mode results in poor practicality. When multiple medical devices are mounted on the bed, the overall weight of the bed increases. Supporting it by direct lifting puts the weight directly on the boom or hydraulic mechanism, which can easily exceed its load-bearing capacity and cause accidents. In view of this, we propose an ICU-assisted lifting device. Summary of the Invention
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an ICU auxiliary transport device to solve the technical problem that the current transport device has a single working mode, is inconvenient to adapt to different operating conditions, and has poor practicality.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an ICU auxiliary lifting device, including a sliding component and a lifting mechanism. The sliding component is slidably sleeved on the outside of a support, and the bottom of the support is installed on the upper rear end of the base. The sliding component is composed of a side frame, a connecting frame, and a rear connecting rod. The bottom of the support is provided with a hydraulic device, and the top of the hydraulic device is fixed on the rear connecting rod. The lifting mechanism is installed on the front side of the sliding component. The lifting mechanism is composed of a pad frame and a lifting plate. One end of the lifting plate is attached to the lower end of the pad frame, and the outer end of the lifting plate is provided with a beveled end.
[0006] In use, this invention involves pushing the device to move via the bottom rollers, inserting the lifting plate under the hospital bed. When lifting lighter beds, the hydraulic system is activated to raise the sliding assembly. During this raising process, the limiting rollers inside the side frame rotate in contact with the support, reducing friction and ensuring operational stability. The sliding assembly simultaneously raises the lifting mechanism, whose lifting plate directly lifts the hospital bed. This structure achieves direct lifting and transport, reducing friction and energy loss through the limiting rollers. The forklift-like lifting mechanism simplifies operation. For heavier beds… During lifting, the hydraulic rod is activated to unfold. The bottom of the hydraulic rod, via a moving hinge, lowers the rear end. At this time, the lifting plate deflects through the rotating shaft, raising the inclined end of the lifting plate. During the lifting process, the rotating cylinder on the lifting plate rolls under the bed, reducing friction. When the deflection reaches its maximum value, the bed rests on the upper side of the inclined end. At this point, the rotating cylinder and roller are on the same horizontal plane, facilitating repositioning. Through the above structural design, this device achieves tilting support through the principle of a lever structure. The lever arm of the pressing part is longer than that of the force-bearing part, which can effectively reduce the stress on the hydraulic rod during the support process, ensuring its service life while reducing the probability of damage.
[0007] Preferably, the rear end of the base is connected to the top of the bracket via a push rod, the push rod being L-shaped and the two ends of the push rod being connected and fixed by bolts.
[0008] Preferably, the sliding assembly has two side frames, and the front and rear ends of the two sliding assemblies are connected and fixed by a connecting frame and a rear connecting rod, respectively, and a connecting rod is fixed to the upper outer side of the connecting frame.
[0009] Preferably, the inner side of the side frame is arrayed with limiting rollers, the side rod of the bracket passes through the inside of the side frame, and two adjacent limiting rollers clamp the outer side of the bracket.
[0010] Preferably, a sleeve is fixed to the top of the pad frame, and the sleeve is sleeved and fixed to the corresponding connecting rod. A hydraulic rod is fixed to the rear side of the pad frame, and a movable hinge is rotatably installed at the bottom of the inner rod of the hydraulic rod.
[0011] Preferably, the lower ends of the pad frame are fixed with side support plates on both sides. The side support plates are L-shaped and the front end of the side support plates is attached to the outer side of the lifting plate. The middle of the two sides of the lifting plate is rotatably installed between the two side support plates through a rotating shaft.
[0012] Preferably, the inclined end of the outer end of the lifting plate is designed to be deflected downward by 20 degrees, and a roller is rotatably installed in the recess on the upper end face of the inclined end via a rotating shaft, and a rotating cylinder is rotatably installed in the recess at the corner of the lifting plate and the inclined end via a rotating shaft.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the design of a sliding component, allows for the lifting of a relatively light hospital bed. The hydraulic system is activated to lift the sliding component, and during this lifting process, the limiting rollers inside the side frame rotate in contact with the support, reducing friction during lifting and ensuring operational stability. Simultaneously, the sliding component drives the lifting mechanism upwards, and the lifting plate of the lifting mechanism directly lifts the hospital bed. This structure achieves direct lifting and transport, reducing friction and energy loss during lifting by using the limiting rollers. Furthermore, the lifting is accomplished using a forklift-like mechanism, simplifying the operation.
[0015] 2. This utility model also incorporates a lifting mechanism. When lifting a heavy hospital bed, the hydraulic rod is activated to unfold. The bottom of the hydraulic rod, via a moving hinge, lowers the rear end. At this time, the lifting plate deflects through the rotating shaft, raising the inclined end of the lifting plate. During the lifting process, the rotating cylinder on the lifting plate rolls under the hospital bed, reducing friction. When the deflection reaches its maximum value, the hospital bed rests on the upper side of the inclined end. At this point, the rotating cylinder and roller are on the same horizontal plane, facilitating repositioning. Through the above structural design, this device achieves tilting support through the principle of a lever structure. The lever arm of the pressing part is longer than that of the force-bearing part, which can effectively reduce the force on the hydraulic rod during the support process, ensuring its service life while reducing the probability of damage.

[0024] As shown in Figures 1 to 5, this utility model relates to an ICU assisted transport device, including a sliding component 2 and a transport mechanism 5. The sliding component 2 is slidably sleeved on the outside of a support 3, and the bottom of the support 3 is installed on the upper rear end of a base 4. The sliding component 2 is composed of a side frame 201, a connecting frame 202, and a rear connecting rod 205. A hydraulic device 301 is provided at the bottom of the support 3, and the top of the hydraulic device 301 is fixed to the rear connecting rod 205. The rear end of the base 4 is connected to the top of the support 3 via a push rod 1. The push rod 1 has an L-shaped design, and both ends of the push rod 1 are connected and fixed by bolts. There are two side frames 201 on the sliding component 2, and the front and rear ends of the two sliding components 2 are connected and fixed via the connecting frame 202 and the rear connecting rod 205, respectively. A connecting rod 203 is fixed at the upper end. Limiting rollers 204 are arrayed on the inner side of the side frame 201. The side rod of the bracket 3 passes through the inside of the side frame 201, and two adjacent limiting rollers 204 clamp the outer side of the bracket 3. When lifting a lightly injured bed, the hydraulic device 301 is activated to drive the sliding component 2 to rise. During the rising process, the limiting rollers 204 inside the side frame 201 rotate in contact with the bracket 3 to reduce the friction during the lifting process and ensure the stability of operation. The sliding component 2 synchronously drives the lifting mechanism 5 to rise. The lifting plate 504 of the lifting mechanism 5 directly lifts the bed. The above structure completes the direct lifting and transporting. The limiting rollers 204 reduce the friction during the lifting process and reduce the energy loss. At the same time, the lifting is completed in the form of a forklift, which reduces the difficulty of operation.
[0025] As shown in Figures 3 to 7, the present invention relates to an ICU auxiliary transport device, including a sliding assembly 2 and a transport mechanism 5. The transport mechanism 5 is installed on the front side of the sliding assembly 2 and consists of a pad frame 502 and a lifting plate 504. One end of the lifting plate 504 is attached to the lower end of the pad frame 502, and the outer end of the lifting plate 504 is provided with a beveled end 505. A sleeve 501 is fixed to the top of the pad frame 502, and the sleeve 501 is sleeved and fixed on the corresponding connecting rod 203. A hydraulic rod 508 is fixed to the rear side of the pad frame 502, and a movable hinge 509 is rotatably installed at the bottom of the inner rod of the hydraulic rod 508. Side support plates 503 are fixed to both sides of the lower end of the pad frame 502. The side support plates 503 are L-shaped, and the front end of the side support plates 503 is attached to the outer side of the lifting plate 504. The middle of both sides of the lifting plate 504 is rotatably installed between the two side support plates 503 through a rotating shaft. The inclined end 505 of the outer end of the lifting plate 504 is designed to be tilted downward by twenty degrees. A roller 506 is rotatably mounted in the recess on the upper end face of end 505 via a rotating shaft. A rotating cylinder 507 is rotatably mounted in the recess at the corner of the lifting plate 504 and the inclined end 505 via a rotating shaft. When lifting a heavier hospital bed, the hydraulic rod 508 is activated to complete the unfolding. The bottom of the hydraulic rod 508 drives the rear end 510 to descend via the moving hinge 509. At this time, the lifting plate 504 is deflected through the rotating shaft, causing the inclined end 505 of the lifting plate 504 to rise. During the lifting process, the lifting plate 506... The rotating drum 507 on 04 rolls at the bottom of the bed to reduce friction. When it deflects to its maximum value, the bed rests on the upper side of the inclined end 505. At this time, the rotating drum 507 and the roller 506 are in the same horizontal plane, which facilitates resetting. Through the above structural design, this device completes the tilting support through the principle of lever structure. The lever arm of the pressing part is longer than the lever arm of the force-bearing part, which can effectively reduce the force on the hydraulic rod 508 during the support process, ensuring its service life while reducing the probability of damage.
[0026] Working Principle: This embodiment provides an ICU assisted lifting device. In use, the device is moved via the bottom rollers, inserting the lifting plate 504 under the bed. When lifting a lighter bed, the hydraulic device 301 is activated, driving the sliding assembly 2 upwards. During this upward movement, the limiting rollers 204 inside the side frame 201 rotate in contact with the support 3, reducing friction during lifting and ensuring operational stability. Simultaneously, the sliding assembly 2 drives the lifting mechanism 5 upwards, and the lifting plate 504 of the lifting mechanism 5 directly supports the bed. When lifting a heavier hospital bed, the hydraulic rod 508 is activated to unfold. The bottom of the hydraulic rod 508 drives the rear end 510 to descend via the moving hinge 509. At this time, the lifting plate 504 deflects through the rotating shaft, raising the inclined end 505 of the lifting plate 504. During the lifting process, the rotating cylinder 507 on the lifting plate 504 rolls at the bottom of the hospital bed to reduce friction. When the deflection reaches its maximum value, the hospital bed is placed on the upper side of the inclined end 505. At this time, the rotating cylinder 507 and the roller 506 are in the same horizontal plane, which facilitates repositioning.
