Jilin University to Transfer Fully Automated Patient Transfer Bed Patent for RMB 330,000

Recently, Jilin University released a public notice on the transformation of scientific and technological achievements, in which the hospital proposed to transfer via agreed pricing method.“Transfer Bed for Fully Automated Patient Handling Throughout the Entire Process”Relevant patents are assigned to the industry party, with a transfer fee of RMBRMB 330,000. The inventor of this patented technology isZhang Guangwei and his team。

The core application of the present invention is to achieve fully automated patient transfer across various scenarios, such as between a transport stretcher and a hospital bed, operating table, or ambulance, without requiring manual handling by medical staff. This reduces workload while enhancing the safety and efficiency of patient transport. It addresses a key pain point of traditional transport stretchers: the height discrepancies among different medical equipment (e.g., hospital beds and operating tables) and the need for reserved operational space during transfer, which previously forced medical personnel to exert considerable effort in lifting and moving patients.

Medical TransportAs a critical component of clinical diagnosis and treatment, it involves the transfer of patients between beds and operating tables, ambulances and wards, as well as between beds in different departments. Its efficiency and safety directly impact the effectiveness of medical care.

However, in current clinical transport scenarios, the design flaws of traditional transport beds have highlighted numerous pain points: various medical devices (such as operating tables, hospital beds, and ambulance stretchers) vary significantly in height, resulting in substantial height discrepancies. Furthermore, the need to reserve operational space for medical staff during transport necessitates that patient transfers rely on manual lifting.

Such patient transport scenarios impose multiple stresses on both healthcare providers and patients. For postoperative patients who are physically debilitated, critically ill and bedridden, or unable to move independently due to fractures, manual lifting and carrying can easily cause shifts in body position. This may exacerbate their condition, induce pain, and even pose risks such as wound dehiscence and secondary injuries.

For healthcare professionals, the long-term repetition of lifting movements not only imposes significant physical strain but also predisposes them to occupational injuries such as lumbar and back strain. Particularly when dealing with heavier patients or in emergency scenarios, relying solely on manual labor makes it difficult to transfer patients quickly and smoothly, which severely compromises transport efficiency and the timeliness of medical intervention.

Currently, mainstream patient transfer solutions still primarily rely on traditional stretchers combined with manual assistance. Some improved transfer beds only offer a single lifting function and fail to address the issue of horizontal transfer between devices, thus still requiring medical staff to manually move patients across height differences and spatial gaps.

A minority of devices with transfer capabilities suffer from drawbacks such as complex structures, cumbersome operations, and high costs, making them difficult to widely deploy in settings like general wards and ambulances.

Furthermore, existing transport equipment generally lacks effective cushioning and protective designs, making it prone to jolting and shaking during transfer, which further exacerbates patient discomfort and safety risks.

These pain points have created an urgent market need for a new type of patient transfer device featuring a streamlined structure, user-friendly operation, and automated lifting and rotational transfer capabilities. Such innovation aims to fill the gap left by traditional solutions in terms of “labor-saving, safety, and efficiency,” thereby addressing the core challenges in medical patient transport.

Leveraging its innovative structural design and precise functional adaptation, this automated transfer bed not only resolves the challenges associated with traditional patient transfers but also demonstrates “"Highly automated, safe and stable, simple and easy to use"These three core advantages comprehensively enhance the practicality and reliability of medical transportation.

Equipment withSingle Lifting AssemblyAs the core driving force, the threaded engagement between the lead screw and the turntable achieves an integrated linkage of “lifting + rotation.” Specifically, the turntable rotates synchronously while moving vertically, driving the movable plate and the patient-bearing bed board to complete the fully automated process of “lifting – rotation – positioning – lowering.”

During this process, there is no need for medical staff to manually lift and transport patients or repeatedly adjust equipment positions; simply activating the component enables precise transfer of the patient to the target hospital bed or above the operating table. This approach significantly reduces labor input during transportation and effectively prevents occupational injuries among healthcare workers caused by repetitive lifting motions. Particularly in challenging scenarios involving critically ill or obese patients, this device can substantially improve transfer efficiency.

Multiple protection mechanisms ensure safe and stable transportation. Equipped with precise positioning functionality to guarantee deviation-free operation. The ring groove within the ring seat adopts“Straight-Edge Groove + Semicircular Groove”The combined design ensures that the movable plate rises and lowers smoothly while the cylinder is within the semicircular groove; the rotational motion is initiated only after it enters the straight-sided groove, thereby preventing patient deviation during elevation and descent and ensuring precise alignment with the target equipment.

PossessShock Absorption and Cushioning Function, effectively preventing jolts. The aluminum ring on the outer side of the rotating shaft and the magnet at the base of the support form a buffering structure. Leveraging Lenz’s law, when the rotating shaft moves downward, an induced current is generated in the aluminum ring, which opposes the movement of the magnet, thereby cushioning the impact force during descent. This prevents severe shaking during transport and reduces the risk of wound dehiscence and aggravation of the patient’s condition postoperatively.

Adopts an anti-drop safety design, the top of the bed board is equipped with a headboard support panel and a footboard guard panel, which can effectively prevent patients from falling during rotation and lifting, further enhancing the safety of transport.

The core transmission structure of the device consists solely of key components such as a lead screw, turntable, cylinder, and ring seat, without any complex or redundant design. This not only reduces the probability of equipment failure and maintenance costs but also facilitates flexible placement in space-constrained settings such as patient wards, operating rooms, and ambulances.

Meanwhile, the bed board and the movable plate adoptLocking Block - Locking Slotto form a movable connection. After transport positioning, medical staff can directly lift the bed board to transfer the patient, making the operation process simple and straightforward. Moreover, this device does not rely on complex external auxiliary tools, is compatible with medical equipment of varying heights, offers strong versatility, and meets the needs of medical transport in multiple scenarios.

The current market for medical transport equipment has taken shape“Traditional Manual Equipment + Intelligent Automated Equipment”a dualistic landscape. Leading enterprises and innovative brands are actively investing in automated transport technology, with R&D efforts centered on “reducing labor dependency and enhancing safety.” Nevertheless, differences persist among products in terms of structural design and functional adaptability.
