Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, and more specifically, to a patient transport device suitable for confined areas. Background Technology

[0002] In clinical treatment and nursing care, the transfer of critically ill or immobile patients between beds, to examination equipment (such as CT and MRI), or to surgical trolleys is a frequent and critical operation. Common scenarios include bed adjustments within wards, transfers to other departments, and external examinations, often involving narrow ward corridors, elevator spaces, and medical environments requiring collision avoidance. Currently, most medical institutions still rely on manual transport, where multiple medical staff work together using sheets, stretchers, and other tools to lift and carry patients. This traditional transport model typically requires at least two or more nurses working together, resulting in high labor costs and low efficiency. Furthermore, during transport, it is difficult to maintain even and stable force control, which can cause secondary injuries such as bone displacement and internal bleeding in some critically ill, fractured, or postoperative patients, directly threatening their safety.

[0003] To reduce manual labor and improve transport safety, some auxiliary transfer devices have emerged on the market, such as bed transfer aids, sliding boards, or simple roller stretchers. While these devices can reduce labor intensity to some extent, their functions are relatively limited, typically only suitable for short-distance, straight-line planar transfers, lacking adaptability to narrow spaces (such as ward corridors less than 90cm wide or home elevators). Specifically, many current transport devices cannot achieve flexible lifting, rotation, and precise positioning in extremely narrow spaces while ensuring the patient's body posture remains stable. Some devices may solve the lifting problem, but their rotation function is inadequate; others, while considering mobility, lack overall structural rigidity and stability, posing risks during hoisting and transfer. Therefore, there is an urgent need for a comprehensive solution that integrates stable support, flexible movement, vertical lifting, horizontal rotation, and safe hoisting. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a patient transport device specifically designed for confined spaces. This device can flexibly navigate narrow areas inaccessible to conventional medical equipment, enabling the smooth and safe transfer of patients within limited spaces. The core design concept of this device lies in modular integration and decoupling of degrees of freedom. Through the coordinated operation of base movement, rotating seat rotation, vertical movement of the lifting mechanism, and boom hoisting, the device ensures a stable center of gravity during patient transport, preventing equipment tipping or patient slippage. This allows for transport tasks to be completed by a single person or with minimal manpower, reducing the physical demands on the operator.

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

[0006] A patient transport device for confined areas includes: a base 1, a central shaft 1-1, casters 2, fixed wheels 3, a rotating seat 4, mounting holes 4-1, a bearing 5, a vertical guide rod 6, a linear guide component 7, a middle guide rod fixing plate 8, an electric push rod 9, an upper balance bracket 10, a lower balance bracket 11, a battery 12, a top guide rod fixing plate 13, a boom 14, and a quick-release hook 15.

[0007] To further illustrate the method of patient transfer using the device of the present invention, the auxiliary equipment used in the application of the device of the present invention also includes: a weight-bearing pad 16, a weight-bearing ring 17, a weight-bearing rope 18, a hospital bed 19, a patient model 20, and a transfer bed 21. The equipment shown in the above numbers does not constitute a structural component of the device of the present invention.

[0008] Furthermore, the base 1 is provided with a set of traveling wheels at its bottom, which consists of a swivel wheel 2 located at the front of the base 4 and a fixed wheel 3 located at the rear of the base 1.

[0009] Furthermore, the rotating seat 4 is rotatably connected to the base 1 via a bearing 5. Specifically, the inner ring of the bearing 5 is fixed to the central shaft 1-1 of the base 1, and the outer ring is fixed within the mounting hole 4-1 of the rotating seat 4. This allows the rotating seat 4 to rotate horizontally 360 degrees relative to the base 1, which is crucial for transferring the patient 20 from the hospital bed 19.

[0010] Furthermore, the device also includes a lifting mechanism, which is the power core of the device. It includes at least three vertical guide rods 6 fixedly installed above the end of the rotating seat 4 connected to the central shaft 1-1, a linear guide component 7, a middle guide rod fixing plate 8, an electric push rod 9, an upper balance bracket 10, a lower balance bracket 11, a battery 12, and a top guide rod fixing plate 13.

[0011] Preferably, the lifting mechanism uses four vertical guide rods 6, which are connected by a middle guide rod fixing plate 8 and a top guide rod fixing plate 13 to form a robust integrated frame structure. This structure can greatly enhance the stability of the lifting mechanism.

[0012] Furthermore, the electric push rod 9 is an electric push rod, with its upper part fixed to the bottom of the boom 14 via an upper balance bracket 10, and its lower part connected to the rotating seat 4 via a lower balance bracket 11. The electric push rod 9 is powered by a battery 12 fixed to the middle guide rod fixing plate 8.

[0013] Furthermore, the vertical guide rod 6 is connected to the boom 14 by a linear guide component 7, which enables the boom 14 to rotate synchronously with the rotation of the rotating seat 4.

[0014] Furthermore, the device also includes a boom 14, which is slidably connected to the vertical guide rod 6 via a linear guide component 7 and connected to the upper balance bracket 10 at the upper end of the electric push rod 9.

[0015] Furthermore, the boom 14 is provided with a plurality of hooks 15 for connecting the patient 20 support, and the hooks 15 are typically a number of quick-release hooks 15 arranged on both sides along the longitudinal axis of the boom 14.

[0016] Preferably, the hook 15 is a snap-on hook with an automatic locking function, so as to achieve a quick and safe connection with the load-bearing rope 18 on the load-bearing rings 17 on both sides of the multi-ring load-bearing pad 16 under the patient 20's body.

[0017] Furthermore, the method for patient transfer using the device of the present invention specifically includes the following steps:

[0018] (1) In the preparatory step 1 of the device, the multi-ring support pad 16 is laid flat on the hospital bed 19 and placed under the body of the patient 20. The support rings 17 of the multi-ring support pad 16 are evenly distributed on the key stress points of the patient 20's torso, such as the shoulders, hips and knees, in order to avoid local pressure concentration.

[0019] (2) Preparatory step 2 of the device: Push the device to the end of the bed and push the base 1 into the end of the bed 19. Adjust the position by the front caster 2 and the rear fixed caster 3 to make the base 1 parallel to the short side of the end of the bed 19.

[0020] (3) Positioning and connection steps: Manually drive the rotating seat 4 to rotate through the bearing 5, so that the boom 14 and the rotating seat 4 rotate 90 degrees synchronously and at the same angle. At this time, the longitudinal axis of the rotating seat 4 and the boom 14 is perpendicular to the tail of the bed 19 and parallel to the longitudinal axis of the patient 20. Turn on the power and start the electric push rod 9 to lower the boom 14 along the vertical guide rod 6 to an appropriate height. Quickly snap the load-bearing rope 18 on the load-bearing ring 17 of the multi-ring load-bearing pad 16 into the quick-release hook 15 to achieve the connection between the boom 14 and the load-bearing pad 16.

[0021] (4) Lifting and transfer steps of the device: The electric push rod 9 lifts the boom 14 at a uniform speed (e.g., 5-10 cm / s), and the sliding between the linear guide component 7 and the vertical guide rod 6 ensures no shaking. After the device is lifted, the rotating seat 4 rotates clockwise, suspending and transferring the patient 20 directly above the transfer bed 21, parallel to the longitudinal axis of the transfer bed 21. The rotation angle is flexibly controlled by the operator according to space constraints.

[0022] (5) The placement steps of the device: the electric push rod 9 slowly descends, so that the patient 20 makes stable contact with the surface of the transfer bed 21. Then, the connection between the quick-release hook 15 and the load-bearing rope 18 is released in sequence, and the patient 20 is placed stably on the transfer bed 21.

[0023] The advantages of this invention compared to the prior art are as follows:

[0024] (1) Excellent spatial adaptability: The device of the present invention has a compact structure and the base 1 is flexible to move. Combined with the 360-degree rotation function of the rotating seat 4, it can move freely and accurately position itself in extreme spaces such as narrow passages and wards with a width of less than 1 meter, effectively solving the problem that traditional transport equipment "can enter but cannot rotate".

[0025] (2) Safe and stable operation, greatly reducing the risk of secondary injury: The lifting mechanism of the device of this invention is driven by an electric push rod 9, which runs smoothly and with low noise. The integrated frame formed by the vertical guide rod 6, the middle guide rod fixing plate 8, and the top guide rod fixing plate 13 ensures the rigidity and stability of the lifting process and effectively prevents shaking. The combined use of the multi-ring load-bearing pad 16 and the quick-release hook 15 can distribute the force and ensure that the patient 20 maintains a stable posture during the lifting and transfer process, maximizing the protection of the patient from secondary injury.

[0026] (3) Labor-saving and efficient, reducing the burden on medical staff: Mechanized and electric operation replaces the traditional manual lifting and carrying. Usually only one medical staff member is needed to complete the entire transfer process, which significantly reduces labor intensity and improves transfer efficiency.

[0027] (4) High functional integration and multi-purpose: The device of this invention integrates the functions of moving, rotating, lifting and hoisting. A single person can complete the complex spatial transfer from the hospital bed to the transport bed through simple operation steps. It is suitable for various narrow areas such as hospital wards, ICU, and emergency room, and has high practical value and promotion prospects. Attached Figure Description

[0039] Example 1:

[0040] like Figure 1 As shown, the present invention provides a patient transfer device for narrow areas, including a base 1, a rotating seat 4, a lifting mechanism, and a boom 14.

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a patient transport device for narrow areas specifically includes: a base 1, a central shaft 1-1, casters 2, fixed wheels 3, a rotating seat 4, mounting holes 4-1, a bearing 5, a vertical guide rod 6, a linear guide component 7, a middle guide rod fixing plate 8, an electric push rod 9, an upper balance bracket 10, a lower balance bracket 11, a battery 12, a top guide rod fixing plate 13, a boom 14, and a quick-release hook 15.

[0042] Furthermore, such as Figure 1 , Figure 2 As shown, the base 1 of the device is equipped with a set of wheels, which consists of two omnidirectional wheels 2 located at the front of the base 1 and two fixed wheels 3 located at the rear. This layout ensures both the flexibility of movement of the device and good stability in straight-line travel, making it easy to operate in narrow passages.

[0043] Preferably, a cylindrical central shaft 1-1 is provided at the center above the plane of the base 1, and its height is preferably 2-3 times that of the bearing 5.

[0044] Furthermore, such as Figure 1 and Figure 2 As shown, the rotating seat 4 is rotatably connected to the base 1 via a bearing 5. The inner ring of the bearing 5 is fixed to the central shaft 1-1 of the base 1, and the outer ring is fixed in the mounting hole 4-1 of the rotating seat 4, which allows the rotating seat 4 to rotate 360 ​​degrees horizontally relative to the base 1.

[0045] Furthermore, such as Figure 1 , Figure 2 As shown, the device also includes a lifting mechanism, which is specifically composed of at least three vertical guide rods 6, a linear guide component 7, a middle guide rod fixing plate 8, an electric push rod 9, an upper balance bracket 10, a lower balance bracket 11, a battery 12, and a top guide rod fixing plate 13, which are fixedly installed above the central shaft 1-1 of the rotating seat 4. This mechanism is the power core of the device of the present invention.

[0046] Furthermore, such as Figure 1 , Figure 2 As shown, the lifting mechanism preferably uses four vertical guide rods 6 as the core support structure, and is connected to the middle guide rod fixing plate 8 and the top guide rod fixing plate 13 respectively to form an integrated frame structure, which greatly enhances the stability of the lifting mechanism; the upper part of the electric push rod 9 is fixed to the bottom of the boom 14 through the upper balance bracket 10, and the lower part of the electric push rod 9 is connected to the rotating seat 4 through the lower balance bracket 11; the power of the electric push rod 9 can be provided by the battery 12 fixed on the middle guide rod fixing plate 8, or connected to an external power source.

[0047] Furthermore, such as Figure 1 , Figure 2As shown, the device also includes a boom 14, which is slidably connected to a vertical guide rod 6 via a linear guide component 7 and connected to an upper balance bracket 10 below an electric push rod 9. Preferably, the boom 14 is provided with multiple hooks 15 for connecting the patient support component. These hooks are several quick-release hooks 15 arranged on both sides along the longitudinal axis of the boom 14. Preferably, the hooks 15 are snap-on hooks with an automatic locking function to achieve quick and safe connection with the load-bearing ropes 18 on the load-bearing rings 17 on both sides of the multi-ring load-bearing pad 16 under the patient 20.

[0048] Example 2:

[0049] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the specific implementation steps of the method for transferring patients using the narrow area patient transfer device of the present invention are as follows:

[0050] 1. Initialization and positioning of the device: Before the device is transferred, the initialization and positioning of the device must be completed.

[0051] (1) Preparatory step 1: Lay the multi-ring support pad 16 flat on the hospital bed 19. Its support rings 17 should be evenly distributed on the key stress points of the patient's trunk (such as the shoulders, buttocks and knees) to avoid local pressure concentration. The multi-ring support pad 16 can be made of high-strength nylon material. The number of support rings on both sides is preferably 4-6 to accommodate patients of different body types.

[0052] (2) Preparatory Step 2: Push the base 1 into the narrow space at the rear of the bed 19 (e.g., the width of the ward passage is <1 meter). Adjust the position using the front casters 2 and the rear fixed casters 3 to make the base 1 parallel to the short side of the bed 19, and control the distance between the front end of the rotating seat 4 and the bed leg of the bed 19 to be 30-50cm to ensure no interference during rotation. Figure 3 As shown, the relative positions of the device with the hospital bed 19, the patient 20, and the transfer bed 21 before hoisting are shown.

[0053] 2. Positioning and connection steps of the device: The rotation of the rotating seat 4 and the connection of the boom 14 must be accurate and safe.

[0054] (1) Rotation control: The rotating seat 4 is manually driven to rotate through the bearing 5, so that the boom 14 is aligned with the patient 20 on the bed 19. The bearing 5 is preferably a thrust ball bearing with a load capacity of ≥500kg to ensure smooth rotation without jamming.

[0055] (2) Hook Connection: Operate the electric push rod 9 to lower the boom 14 along the vertical guide rod 6 to an appropriate height. The quick-connect hook 15 is an automatic locking buckle that quickly connects to the load-bearing rope 18 on the multi-ring load-bearing pad 16 and load-bearing ring 17. The load-bearing rope 18 is made of low-elongation polyester rope with adjustable length to maintain the patient's horizontal posture. Figure 3 , Figure 4 As shown, a partially enlarged view of the multi-ring load-bearing pad 16 highlights the distribution of the load-bearing rings 17. (As shown...) Figure 4 As shown, the device is positioned relative to the hospital bed 19, the patient 20, and the transport bed 21 when the connection is completed.

[0056] 3. The steps for lifting, transferring, and placing the device:

[0057] (1) Lifting process: The electric push rod 9 lifts the boom 14 at a constant speed (e.g., 5-10 cm / s), and the sliding between the linear guide component 7 and the vertical guide rod 6 ensures no swaying. The battery 12 is a lithium-ion battery with a capacity of ≥20Ah, supporting ≥10 continuous lifting cycles.

[0058] (2) Rotational transfer: After lifting, the rotating seat 4 rotates clockwise by 0-180 degrees to suspend and transfer the patient 20 above the transport bed 21. The rotation angle is flexibly controlled by the operator according to space constraints, as long as the position of the bed legs of the patient bed 19 is avoided.

[0059] (3) Safe Placement: The electric push rod 9 slowly descends, allowing the patient 20 to smoothly contact the surface of the transfer bed 21, and then the quick-release hooks 15 are disconnected sequentially. Throughout the process, the patient's body tilt angle is <5° to avoid spinal shear force. Figure 4 As shown, the relative positions of the device, patient, and transfer bed are shown after the device is hoisted. Figure 5 As shown, the relative positions of the device of the present invention with the patient, the support pad, and the transfer bed when the device is installed after hoisting is completed.

[0060] 4. Measures to enhance the stability and safety of the device:

[0061] (1) Structural reinforcement: Four vertical guide rods 6 form a frame through the middle guide rod fixing plate 8 and the top guide rod fixing plate 13, with a bending stiffness ≥1000N / m. The upper balance bracket 10 and the lower balance bracket 11 adopt a floating support design to ensure that the electric push rod 9 moves in a straight line.

[0062] (2) Emergency mechanism: The device is equipped with manual overload protection. When the load on the electric push rod 9 exceeds 300kg, it will automatically cut off the power to ensure safety.

[0063] This invention has a simple structure and is easy to operate. It is suitable for narrow areas such as wards or corridors in medical institutions or nursing homes, and effectively solves the space limitations and safety hazards of traditional transfer equipment.

[0064] Finally, it should be noted that the apparatus and methods described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
