Description

Technical Field

[0001] This utility model relates to the field of rescue and transportation technology, specifically to a non-contact pushing device for transferring rescue targets. Background Technology

[0002] When resuscitating emergency patients, it is necessary to transfer them to the emergency room in a timely manner using transport equipment. The transport equipment consists of a transport vehicle and a stretcher. The stretcher is movably mounted on the transport vehicle, which can realize the rapid transfer of patients and buy more time for rescue. A prior art patent, CN222533523U, discloses an emergency transfer device comprising a chassis, drive wheels, and steering wheels. The drive wheels are located on both sides of the center of the chassis, and the steering wheels are rotatably mounted at both ends of the chassis. A support base is welded to the upper surface of the chassis, and a lifting cover is fitted onto the surface of the support base. An electric telescopic rod is installed inside the support base, and the piston rod end of the electric telescopic rod is connected to the top of the inner cavity of the lifting cover. A lifting plate is welded to the top of the lifting cover, and a stretcher is movably mounted on the surface of the lifting plate. A battery is installed at the bottom of the inner cavity of the support base, and a drive motor is installed inside the chassis. The power output end of the drive motor is connected to one set of drive wheels. The beneficial effects achieved by this invention are: the transfer vehicle can be moved electrically during use, making transfer more labor-saving; and the height of the transfer vehicle can be adjusted to accommodate emergency personnel of different heights, making it more flexible to use.

[0003] However, while the patented technical solution improves mobility and basic lifting functions, it remains essentially a contact-based transport solution. Patients need to be directly moved or rolled onto the stretcher platform, or placed on the stretcher first using other auxiliary equipment. During transport, the patient's body remains in continuous contact with the stretcher surface. When the equipment moves or encounters bumps, the static friction between them may turn into kinetic friction, causing additional harm to patients with burns, abrasions, or fractures, thus lacking in medical adaptability.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0019] like Figures 1-8 As shown, this embodiment proposes a non-contact pushing device for transferring rescue targets, including a placement body 100; The top of the placement body 100 is provided with a pre-laying component 200 for patient placement, the bottom of the pre-laying component 200 is provided with a lifting component 300 for patient lifting and transfer, and the bottom of the lifting component 300 is provided with an auxiliary component 400 for assisting patient transfer.

[0020] The rescue target transfer utilizes a non-contact delivery device, comprising a stand-alone placement body 100, a pre-laying component 200 integrated into the device, a lifting component 300, and an auxiliary component 400. The placement body 100 in this scenario is a stand-alone board-like object, such as a stretcher board or emergency treadmill, used to temporarily support the patient in the initial stages of rescue. The device itself is a movable unit. Its workflow begins with rescuers laying a spare elastic connecting cloth 207 on the stand-alone placement body 100, followed by the patient lying on the elastic connecting cloth 207. When transfer is required, rescuers move the delivery device to the side of the placement body 100, aligning and gripping the pre-laying component 200 on the device. At the free end of the elastic connecting fabric 207, the pre-laying assembly 200 can establish a firm connection with the elastic connecting fabric 207 that is not part of the equipment. Subsequently, the lifting assembly 300 is activated, and through the linear movement of hydraulic or pneumatic actuators, a vertical lifting force is generated to lift the pre-laying assembly 200 and the connected elastic connecting fabric 207 together, thereby smoothly lifting the patient away from the original placement body 100. Finally, the auxiliary assembly 400 uses its bottom moving mechanism to safely transfer the lifted patient to the target position under manual pushing or power drive. Throughout the process, the equipment and the patient achieve non-contact transfer through the elastic connecting fabric 207, avoiding secondary injury to the patient during the handling process.

[0021] The pre-laying assembly 200 consists of a double-sided support plate 201, two inner groove rotating rollers 203, and an insertion rotating roller 204. The double-sided support plate 201 is slidably disposed on both sides of the placement body 100. The inner groove rotating rollers 203 and the insertion rotating rollers 204 are rotatably mounted on the top of the double-sided support plate 201. The insertion rotating rollers 204 are inserted into the inner groove rotating rollers 203. An elastic connecting cloth 207 is detachably connected to both insertion rotating rollers 204. The elastic connecting cloth 207 is slidably disposed between the human body and the placement body 100.

[0022] The pre-laying assembly 200 consists of a double-sided support plate 201, two inner groove rotating rollers 203, and an insert rotating roller 204. The double-sided support plate 201 is slidably mounted on both sides of the main body of the equipment. The inner groove rotating rollers 203 and the insert rotating roller 204 are rotatably mounted on the top of the double-sided support plate 201 via bearings. The insert rotating roller 204 is detachably inserted into the end slot of the inner groove rotating roller 203 for easy replacement and maintenance. Spare elastic connecting cloths 207 are detachably connected to the two insert rotating rollers 204. Before rescue, an independent elastic connecting cloth 207 is pre-laid on the placement body 100, and the patient lies on it. During transfer, the equipment is pushed close, and the rescuers temporarily fix the free end of the elastic connecting cloth 207 of the pre-laying assembly 200 on the equipment to the cloth under the patient using hooks, Velcro, or by direct overlapping. Subsequently, the drive motor drives the inner groove rotating roller 203 to rotate, indirectly and smoothly dragging and pulling the entire piece of cloth under the patient's body, along with the patient, from the placement body 100 through the elastic connecting cloth 207 of the winding device, and finally transferring it to the predetermined position of the device. The principle of the elastic connecting cloth 207 is to use its high elasticity and low friction material properties to form a smooth sliding interface between the patient's body and the placement body 100, making the winding process smooth and effortless, and greatly reducing the transfer resistance.

[0023] A drive motor 202 is installed at one end of the inner groove rotating roller 203. The drive motor 202 is used to rotate the inner groove rotating roller 203 so that the elastic connecting cloth 207 can be extended or retracted. A fixing plate 205 is provided on one side of the insertion rotating roller 204. The fixing plate 205 is threadedly connected to the double-sided support plate 201 by at least two locking bolts 206. The fixing plate 205 is used for the installation of the inner groove rotating roller 203 and the insertion rotating roller 204.

[0024] A drive motor 202 is installed at one end of the inner groove rotating roller 203. The drive motor 202 is usually a servo motor with precise speed control capability. The servo motor converts electrical energy into mechanical torque and directly drives the inner groove rotating roller 203 to rotate in both directions through a coupling, realizing the winding and unwinding of the elastic connecting cloth 207, thereby completing the lifting and lowering action for the patient. During the transmission process, the speed and torque of the motor are strictly controlled to ensure a smooth lifting process and avoid impact on the patient. A fixing plate 2 is provided on one side of the inserted rotating roller 204. 05. The fixing plate 205 is threadedly connected to the double-sided support plate 201 by at least two locking bolts 206. The fixing plate 205 acts as a clamping seat, fixing the ends of the insertion rotating roller 204 and the inner groove rotating roller 203 to the double-sided support plate 201 to withstand the huge tension generated when the patient is pulled. The locking bolts 206 are based on the self-locking characteristics of the threads and the huge friction generated when tightening to form an unloose connection, ensuring that the insertion rotating roller 204 and the inner groove rotating roller 203 remain stable and safe during the operation of the equipment.

[0025] The lifting assembly 300 consists of a lifting plate 301 of the same size as the double-plate support plate, and the lifting plate 301 and the double-plate support plate 201 are movably hinged together by at least two symmetrically arranged hinge shafts 302.

[0026] The lifting plate 301 is positioned between the two side support plates 201 of the pre-laying assembly 200 and is hinged by at least two symmetrically arranged hinge shafts 302. The hinge shafts 302 act as a rotation hub, allowing the lifting plate 301 to rotate relative to the two side support plates 201 in a plane. When the pre-laying assembly 200 pulls the patient from the placement body 100 by winding the elastic connecting cloth 207, the lifting assembly 300 begins to move. The lifting plate 301 rotates around the axis of the hinge shafts 302, thereby lifting the entire pre-laying assembly 200 and the patient supported on it from a horizontal position to a higher, more convenient height for transport. This provides a stable lifting platform for the patient and avoids the discomfort and risks that may be caused by single-point lifting.

[0027] A first sliding shaft 304 is movably hinged to one side of the hinge shaft 302, and a number of hinge plates, equal in number to the hinge shaft 302, are movably hinged to the top of the lifting plate 301. A first cylinder 303 is installed on one side of the hinge plate, and the output end of the first sliding shaft 304 is connected to the first cylinder 303. The first cylinder 303 is used for adjusting the height of the pre-laying component 200.

[0028] A first sliding shaft 304 is movably hinged to one side of the hinge shaft 302. Simultaneously, a number of hinge plates, equal in number to the hinge shaft 302, are movably hinged to the top of the lifting plate 301. A first cylinder 303 is mounted on one side of each hinge plate, and the output end of the first sliding shaft 304 is connected to the first cylinder 303. The first cylinder 303 uses compressed air to drive a piston within its cylinder in a linear motion. When lifting is required, the output end of the first cylinder 303 extends, pushing the first sliding shaft 304. A sliding shaft 304 is hinged to a hinge shaft 302, while the cylinder body is hinged to a hinge plate on the lifting plate 301. This thrust is converted into a torque, forcing the lifting plate 301 to rotate upward around the hinge shaft 302, thereby achieving height increase. Conversely, when the cylinder retracts, the lifting plate 301 descends. Through the linear motion of the first cylinder 303, it is converted into rotational motion via the hinge point, realizing the height adjustment of the pre-laying component 200 and the patient, allowing rescuers to control the lifting height according to the actual situation.

[0029] The auxiliary component 400 consists of a fixing frame 401 disposed at the bottom of the lifting component 300. The fixing frame 401 is provided with a battery module for powering the device. The battery module is composed of a rechargeable battery pack. At least two second cylinders 402 are disposed at the top of the fixing frame 401. The output end of the second cylinder 402 is equipped with a second sliding shaft 403. The second sliding shaft 403 is connected to the lifting plate 301. The second cylinders 402 are used for angle lifting adjustment of the lifting component 300 and the pre-laying component 200.

[0030] The auxiliary component 400 consists of a fixed frame 401 located at the bottom of the lifting component 300. At least two second cylinders 402 are provided on the top of the fixed frame 401. The output end of the second cylinder 402 is equipped with a second sliding shaft 403, and the second sliding shaft 403 is hinged to the lifting plate 301 above. The second cylinders 402 are used for the angle adjustment of the lifting component 300 and the pre-laying component 200, which enhances the responsiveness of the equipment to the patient's medical care needs during transportation.

[0031] The bottom of the fixed frame 401 is provided with at least four symmetrically arranged casters 404, and a push rod 405 is fixedly connected to one side of the fixed frame 401. The push rod 405 and the casters 404 are used for the overall movement of the equipment.

[0032] The base of the mounting frame 401 is equipped with at least four symmetrically arranged casters 404, which can rotate freely 360 degrees, enabling flexible movement of the equipment in all directions on a plane, including straight, lateral, and in-situ turning. A push rod 405 is fixedly connected to one side of the mounting frame 401. The push rod 405 provides rescuers with an ergonomic point of application, allowing them to easily guide the equipment towards the target direction by applying pushing or pulling force. The push rod 405 integrates control devices, allowing operators to control other functions of the equipment while moving. The casters 404 are typically equipped with a foot-locking mechanism, which locks the wheels through mechanical linkages, ensuring stable parking of the equipment after lifting or reaching the destination and preventing accidental slippage. This allows rescuers to transfer patients to a safe area effortlessly, smoothly, and quickly.

[0033] A temporary support plate 208 is slidably inserted into the inside of the bilateral support plate 201. The temporary support plate 208 is used for auxiliary support during patient transfer.

[0034] A temporary support plate 208 is slidably inserted into the interior of the bilateral support plate 201. The temporary support plate 208 has a drawer-like sliding structure, allowing rescuers to pull it out or push it back in from inside the bilateral support plate 201. The core function of this temporary support plate 208 is to provide temporary auxiliary support during patient transfer.

[0035] Working principle: First, an independent elastic connecting cloth 207 is laid on the placement body 100, which serves as a temporary stretcher, and the patient lies on it. When transfer is required, rescuers move the pushing device to the side of the placement body 100, align it using the sliding double-sided support plates 201, and fix the free end of the elastic connecting cloth 207 on the device's pre-laid component 200 to the cloth under the patient. Then, the drive motor 202 starts, driving the inner groove rotating roller 203 to rotate, smoothly winding up the elastic connecting cloth 207. Using the low-friction sliding interface it forms, the patient is gently dragged and pulled from the placement body 100 to the device's predetermined position. Immediately afterwards, the lifting component 300 starts working, and the first cylinder 303 pushes... The first sliding shaft 304 is moved, forcing the lifting plate 301 to rotate upward around the hinge shaft 302, thereby raising the entire pre-laid platform for receiving the patient to a suitable height for transport. During this process, if the patient's position needs to be adjusted, the second cylinder 402 in the auxiliary component 400 can drive the second sliding shaft 403 to adjust the angle of the lifting plate 301. Finally, the rescuers use the push rod 405 on one side of the fixed frame 401 and the omnidirectional movement capability of the bottom caster 404 to safely and smoothly push the patient to the destination. The temporary placement plate 208, which is slidably inserted into the double-sided support plate 201, provides crucial transitional support for the patient's body in the early stages of the transfer, ensuring the smoothness and safety of the entire non-contact transport process.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
