Technical Field
[0001] This invention relates to the field of patient transport technology, specifically to a multi-scenario patient transport device. Background Technology
[0002] In clinical medical care, patient transfer is a frequent and crucial step, especially when transferring patients between different settings such as the operating room, ICU, ward, and imaging room.
[0003] Currently, commonly used transport methods include manual handling, stretchers, and cranes, but these methods generally have the following problems: manual handling is inefficient and risky: it requires the cooperation of multiple people, which can easily cause back injuries to medical staff and poses a risk of secondary injury to patients (especially postoperative or fracture patients); it lacks effective support and fixation for the patient's body position: especially during the transition from lying down to sitting, there is a lack of stable, comfortable and adjustable support structure, which can easily lead to patient discomfort or fluctuations in the patient's condition. Summary of the Invention
[0004] To address the problems mentioned in the background art above, the present invention is implemented through the following technical solution: a multi-scenario patient transfer device, including a base, wherein a lifting main rod capable of being raised and lowered is provided in the base, a support arm is horizontally provided at the top of the lifting main rod, a plurality of pulleys are installed on the lower surface of the support arm, a rope is provided at the free end of the support arm, one end of the rope passes through the pulley and is set inside the base, and the other end is fixedly connected to a hanging piece;
[0005] The hanging component consists of a vertical U-shaped arm and a horizontal U-shaped arm, with the two free ends of the vertical U-shaped arm pointing downwards and fixedly connected to the two support arms of the horizontal U-shaped arm;
[0006] The transport device also includes a dovetail assembly, which consists of an abdomen and two dovetail sections. Connecting ropes are provided on both sides of the abdomen, and connecting ropes are provided at the tails of the two dovetail sections. By connecting the connecting ropes to the transverse U-shaped arm, the dovetail assembly can be used with the hanger for multi-scenario transport of patients.
[0007] Furthermore, the base has two support plates at its bottom, and omnidirectional wheels are provided at the bottom of the base and the bottom of the free ends of the two support plates.
[0008] Furthermore, a cylindrical threaded column is fixedly installed at the lower end of the lifting main rod, and a threaded cylinder is rotatably installed inside the base, with the threaded column and the threaded cylinder engaging in threaded engagement.
[0009] Furthermore, a rotating cylinder is installed inside the base, the lower end of the threaded column is slidably installed inside the rotating cylinder, a fixing plate is fixedly installed on the surface of the rotating cylinder, a gear ring is fixedly installed on the surface of the threaded cylinder, and a motor for driving the gear ring to rotate is installed on the surface of the fixing plate.
[0010] Furthermore, the rotating drum is rotatably mounted on the bottom surface inside the base, and a turntable is fixedly mounted on the surface of the rotating drum. The outer ring surface of the turntable is provided with a toothed surface, which is driven to rotate by a drive motor with a self-locking stop function and a drive gear at the output end of the drive motor.
[0011] Furthermore, the ends of both support plates near the base are rotatably connected to the base, and a gear is fixedly installed on the upper surface of the support plate near the base.
[0012] A gear set is provided between the gear and the turntable, and the gear set is rotatably mounted on the bottom surface inside the base;
[0013] The tooth surface has a fan-shaped tooth structure. When the turntable rotates, the fan-shaped tooth structure on the tooth surface can only mesh with one of the gear sets.
[0014] Furthermore, the gear set consists of two coaxial gears, one large and one small. The large gear can mesh with the tooth surface, and the small gear meshes with the corresponding gear.
[0015] Furthermore, a drum is rotatably mounted inside the base, with one end of the rope located inside the base wound around the surface of the drum.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This multi-scenario patient transport device uses a dovetail component with an abdominal and bilateral dovetail structure to conform to the curves of the human back and legs. With the help of connecting ropes, it can achieve multi-point suspension, distribute pressure, and avoid local compression. It is suitable for various body positions such as lying flat, semi-reclining, and sitting, improving patient comfort and sense of security. At the same time, the use of vertical and horizontal U-shaped arms can improve the stability of the patient transport process.
[0018] 2. This multi-scenario patient transfer device uses a threaded column-threaded cylinder meshing structure to achieve vertical lifting of the main lifting rod, and works with a turntable and drive gear to achieve horizontal rotation from 0 to 90 degrees. No manual lifting is required, and a single person can complete the patient transfer, significantly reducing labor costs and operational intensity. While the main lifting rod rotates, the corresponding side support plate is driven to unfold synchronously through the linkage of the fan-shaped tooth surface and the gear set, forming a dynamic support base, which effectively prevents the device from tipping over due to the shift of the center of gravity, ensuring the safety of patients and medical staff.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] An embodiment of this multi-scenario patient transport device is as follows:
[0028] Please see Figures 1-6 A multi-scenario patient transport device includes a base 1, in which a lifting main rod 201 capable of being raised and lowered is provided. A support arm 3 is horizontally arranged on the top of the lifting main rod 201. Multiple pulleys 4 are installed on the lower surface of the support arm 3. A rope 5 is provided at the free end of the support arm 3. One end of the rope 5 passes through the pulley 4 and is set inside the base 1. The other end is fixedly connected to a hanging piece 6. The height of the hanging piece 6 can be adjusted by means of the lifting main rod 201 and the rope 5.
[0029] The pendant 6 consists of a vertical U-shaped arm 601 and a horizontal U-shaped arm 602. The two free ends of the vertical U-shaped arm 601 are downward and fixedly connected to the two arms of the horizontal U-shaped arm 602. The design of the vertical U-shaped arm 601 and the horizontal U-shaped arm 602 facilitates the subsequent connection of the dovetail assembly and also helps to ensure the patient's horizontal balance.
[0030] The transport device also includes a dovetail assembly, which consists of an abdomen 7 and two dovetail sections 701. Connecting ropes 702 are provided on both sides of the abdomen 7, and connecting ropes 702 are provided at the tails of the two dovetail sections 701. By connecting the connecting ropes 702 to the transverse U-shaped arm 602, the dovetail assembly can cooperate with the hanging piece 6 for multi-scenario transport of patients.
[0031] Specifically, when the patient is in a seated position, such as inside a car, the dovetail assembly is placed on the patient's back, the abdomen 7 provides back support, the two dovetails 701 pass through the inside of the patient's legs, the two connecting ropes 702 in the abdomen 7 are connected to the crossbar between the two arms of the transverse U-shaped arm 602, and the connecting ropes 702 in the two dovetails 701 are respectively connected to the two arms of the transverse U-shaped arm 602. The patient can simply grab the crossbar at the top of the vertical U-shaped arm 601, making it easy to move the patient from the car to a wheelchair or transfer bed.
[0032] When the patient is lying flat, select a dovetail assembly of appropriate size and place it on the patient's back. The abdomen 7 is used to support the patient's body. Two dovetails 701 pass through the inside of the patient's legs. Two connecting ropes 702 in the abdomen 7 are connected to the crossbar between the two arms of the transverse U-shaped arm 602. The connecting ropes 702 in the two dovetails 701 are respectively connected to the free ends of the two arms of the transverse U-shaped arm 602. The patient can grab the crossbar of the transverse U-shaped arm 602 with his / her hands to realize the transfer of the patient and facilitate the patient to be moved to the operating table.
[0033] It should be noted that the bottom of the base 1 is provided with two support plates 12. The bottom of the base 1 and the bottom of the free ends of the two support plates 12 are provided with casters 13. The design of the two support plates 12 is to improve the stability of the base 1 and prevent the entire transport device from tilting when transporting patients.
[0034] It should be noted that a cylindrical threaded column is fixedly installed at the lower end of the lifting main rod 201, and a threaded cylinder 9 is rotatably installed inside the base 1. The threaded column and the threaded cylinder 9 are threadedly engaged. By rotating the threaded cylinder 9, the lifting main rod 201 can be raised and lowered.
[0035] It should be noted that a rotating cylinder 2 is installed inside the base 1. The lower end of the threaded column is slidably installed inside the rotating cylinder 2. A fixing plate 10 is fixedly installed on the surface of the rotating cylinder 2. A gear ring 901 is fixedly installed on the surface of the threaded cylinder 9. A motor that drives the gear ring 901 to rotate is installed on the surface of the fixing plate 10. A gear is installed at the output end of the motor. The gear meshes with the gear ring 901, and the motor drives the threaded cylinder 9 to rotate.
[0036] It should be noted that the rotating drum 2 is rotatably installed on the bottom surface inside the base 1. The rotating drum 2 is fixedly installed on the surface of the rotating drum 2. The outer ring surface of the rotating drum 11 is provided with toothed surfaces 111. The toothed surfaces 111 are driven to rotate by a drive motor with a self-locking stop and a drive gear 15 at the output end of the drive motor. The drive motor drives the rotating drum 2 to rotate, thereby driving the lifting main rod 201 and the support arm 3 to rotate horizontally within a certain range, so as to rotate and transfer the patient within the range of 0-90°.
[0037] It should be noted that the ends of the two support plates 12 near the base 1 are rotatably connected to the base 1, and a gear 121 is fixedly installed on the upper surface of the support plate 12 near the base 1; a gear set 14 is provided between the gear 121 and the turntable 11, and the gear set 14 is rotatably installed on the bottom surface inside the base 1; the tooth surface 111 has a fan-shaped tooth structure, and when the turntable 11 rotates, the fan-shaped tooth structure of the tooth surface 111 can only mesh with one of the gear sets 14.
[0038] When the patient is rotated and transferred within a certain range by rotating the lifting main rod 201, the rotation of the rotating drum 2 will drive the turntable 11 to rotate. The turntable 11 meshes with the gear set 14 on the rotating side of the lifting main rod 201 through the tooth surface 111. The gear set 14 meshes with the corresponding gear 121, which drives the support plate 12 on the side of the lifting main rod 201 to rotate in the same direction. Through the rotation of the support plate 12, it is ensured that the base 1 still has a certain stability while the lifting main rod 201 rotates, so as to prevent the transfer device from tipping over.
[0039] It should be noted that the gear set 14 consists of two coaxial gears, one large and one small. The large gear can mesh with the tooth surface 111, and the small gear meshes with the corresponding gear 121. The design of the gear set 14 is to ensure that the rotation direction of the support plate 12 on the corresponding side is consistent with that of the lifting main rod 201, and to ensure that the rotational angular velocity of the support plate 12 is not lower than that of the lifting main rod 201.
[0040] It should be noted that a drum 8 is rotatably installed inside the base 1. The drum 8 is mounted on the side wall inside the base 1 through the support side plates on both sides. The drum 8 is driven to rotate by a motor installed inside the base 1. The end of the rope 5 located inside the base 1 is wound around the surface of the drum 8. The height of the hanging piece 6 is adjusted by winding and unwinding the rope 5 using the drum 8.
