DESC:Field of the Invention
(001)The present invention relates to the advanced medical device industry, specifically within the domain of emergency and critical care equipment.More particularly, it pertains to the design and implementation of a multifunctional emergency nursing apparatus that integrates automated patient stabilization, injury-prevention mechanisms, and biofluid collection systems.
(002)This invention lies at the intersection of smart clinical support systems, medical robotics interfaces, and hospital logistics optimization, aiming to enhance the efficiency and safety of patient handling during high-risk emergency care and perioperative transport.
(003) The invention also aligns with emerging trends in AI-assisted emergency response platforms, modular healthcare infrastructure, and human-centered biomechanical engineering applied to critical patient mobility and stabilization solutions.
Background of the Invention
(004) In emergency medical environments, time-sensitive intervention and safe patient handling are paramount. Patients admitted to emergency departments are often critically ill or severely injured, requiring immediate stabilization, secure transport, and preparation for surgical or intensive care procedures.
(005) Existing emergency nursing beds and transfer devices exhibit notable shortcomings. Traditional designs are typically static in function, lacking modular components or adaptive systems capable of accommodating various trauma scenarios. These conventional beds require manual lifting or repositioning of patients, which poses several critical risks:
• Exacerbation of existing injuries,
• Increased likelihood of caregiver strain or error,
• Patient falls due to agitation or inadequate restraint,
• Inefficient transfer to surgical tables or diagnostic platforms.
(006) Furthermore, current solutions often neglect integrated biofluid management, leading to potential contamination, compromised hygiene, and disruption of sterile fields in the clinical environment.
(007) Attempts to address these issues through auxiliary attachments or ad hoc procedural workarounds have resulted in complex, time-consuming protocols that fail to ensure patient safety or streamline emergency workflow.
(008) Accordingly, there is a pressing need for a novel emergency care apparatus that unifies secure immobilization, fluid control, and controlled mechanical transfer, while minimizing physical strain and maximizing operational speed and patient safety.
(009) The present invention addresses these deficiencies by introducing a multifunctional emergency nursing device with adaptive mechanical structures, intelligent locking systems, and integrated drainage mechanisms—offering a unified solution for rapid response trauma care.
Summary of the Invention
(010) The present invention provides a multifunctional emergency nursing apparatus specifically engineered to facilitate rapid, safe, and hygienic management of critically injured patients in emergency care settings.
(011) The primary objective of the invention is to offer a mechanically adaptive platform that enables:
• Secure immobilization of the patient’s lower limbs through an adjustable L-shaped fixation mechanism,
• Safe and effortless lateral transfer to an operating table via a slidable patient support board guided by a curved rail and spring-dampened motion control system, and
• Efficient collection and filtration of bodily fluids through integrated drainage and isolation compartments to maintain environmental cleanliness.
(012) The invention further incorporates shock-absorbing support pillars with universal locking wheels for mobile stability and deployability in dynamic clinical environments.
(013) By combining these functional elements, the device minimizes secondary injuries, reduces manual handling risk for healthcare personnel, and ensures continuity of care from triage to surgical intervention.
Detailed Description of the Invention
(014) The present invention will now be described in further detail with reference to the accompanying drawings, which illustrate preferred and alternative embodiments of the Multifunctional Emergency Nursing Apparatus.

Preferred Embodiment
(015) Referring to Figures 1–4, the emergency nursing device comprises a main body frame (2) supported by four load-bearing columns (1), each equipped with 360° rotating universal wheels featuring locking mechanisms to ensure stationary operation during emergency procedures.
(016) The top surface of the body frame is fitted with a longitudinal movable slot (15) that houses a slidable patient support platform (4). This platform allows the patient to be transferred laterally without lifting, reducing handling-induced trauma.
(017) At one longitudinal end of the main frame, dual L-shaped fixation assemblies (3) are symmetrically mounted. Each assembly includes:
• A threaded rod (304),
• An arched mounting plate (301),
• A pressure plate (303), and
• Third compression springs (302) for controlled engagement.
(018) These fixation mechanisms can be adjusted via the threaded rod to secure the patient’s limbs, especially the legs, preventing movement during transport or invasive procedures.
(019) The opposite end of the device includes a pivot-mounted rotation board (6) connected to a telescopic insertion rod (7). The rod is spring-loaded via first springs (9) and attached to a fixing plate (8). This allows controlled insertion/removal from corresponding slots in the support platform to initiate the lateral transfer operation.
(020) A curved guide rail (11) beneath the transfer board guides a slider (10) connected to the rotation board. A guide rod (12) and second springs (16) provide elasticity and shock absorption during movement.
(021) To maintain hygiene and environmental safety, the top surface integrates dual drainage channels (13) on both sides of the movable slot. These channels house removable filtration plates (14) and are connected to liquid collection tanks (5) via fluid egress ports, ensuring real-time separation of solid and liquid medical waste.
Operation
(022) In clinical use, the patient is placed on the support platform (4), and the leg fixation units are engaged by rotating the threaded rods (304) until the pressure plates (303) immobilize the limbs.
(023) During treatment, any bodily fluids flow from the platform into the filtration zone (13), where solid residues are retained by the filter plate (14), and liquids pass through to the collection tank (5), preserving hygiene standards.
(024) For surgical transfer, the insert rod (7) is retracted, disengaging the platform. The rotation board (6) is then pivoted, causing the slider (10) to travel along the guide rail (11), compressing springs (16) to absorb kinetic stress. Once in horizontal alignment with the target surface (e.g., operating table), the platform (4) is slid across seamlessly.
Alternative Embodiments
(025) In another embodiment, the fixation assemblies (3) may be motorized using servo-controlled actuators for hands-free limb restraint, integrating with hospital automation systems.
(026) The drainage and filtration system can be adapted to include smart sensors to monitor fluid levels and automatically trigger alerts or emptying sequences.
(027) The guide rail mechanism (11) may also be configured with electromagnetic locks or hydraulic pistons to regulate resistance and speed during transfer.
(028) Materials used for the support board (4) and housing (2) can be medical-grade antibacterial composites or carbon-fiber-reinforced polymers for improved weight handling and infection control.
(029) The described embodiments illustrate a versatile and clinically optimized emergency nursing device that integrates immobilization, transfer, and sanitation into a compact, mobile platform. Variations in design and control systems do not depart from the spirit and scope of the invention and may be employed to adapt to different medical environments or patient needs.

Examples
Example 1: Emergency Limb Immobilization and Stabilization
A trauma patient is brought into the emergency department with a compound fracture to the lower leg. Immediate stabilization is required to prevent further displacement of the fracture and to prepare the patient for surgery.
• The patient is positioned on the movable support platform.
• The nurse rotates the threaded rods of the L-shaped fixation mechanisms to gently lower the pressure plates onto the patient’s thigh and ankle, securing them with adjustable compression via the springs.
• This immobilizes the leg without excessive force, reducing the risk of further injury from patient movement or transit.
Outcome: The leg remains stable while diagnostic imaging and preoperative preparations are performed. The fixation system ensures no secondary trauma occurs during handling.
Example 2: Seamless Patient Transfer to Operating Table
The same patient is now ready for surgery. Manual lifting is risky due to the patient’s fragile condition and pain response.
• The clinician disengages the insert rod connected to the rotating transfer plate.
• The guide rail and slider system allow the platform to pivot smoothly outward in alignment with the surgical table.
• Using light manual guidance, the support platform is slid laterally onto the operating table surface.
Outcome: The transfer is completed without lifting the patient, ensuring stability, minimizing pain, and preventing strain for medical staff.
Example 3: Fluid Management During Active Hemorrhage
A patient with abdominal trauma is experiencing active external bleeding.
• As the patient is laid on the platform, blood and other body fluids drain via the platform’s surface channels into the filtering troughs.
• Solid particulates (such as coagulated blood and dressing materials) are trapped by the removable filter plates.
• Liquids flow through outlet ports into the collection tanks, preventing spillage and contamination of surrounding areas.
Outcome: The treatment area remains clean, reducing infection risk and improving the sterility of the clinical environment.
Example 4: Use in a Mobile Field Hospital
In a disaster relief camp, a portable version of the emergency nursing apparatus is deployed.
• The apparatus is wheeled to the scene using 360° swivel caster wheels.
• The lockable wheels ensure stability on uneven terrain.
• The support board and fixation system are used to stabilize and transport the patient from a triage tent to a surgical station.
Outcome: The device functions effectively even outside a hospital setting, demonstrating its adaptability and ruggedness in field applications.
