Description
Technical Field
[0001] This utility model relates to a patient transport vehicle, which is particularly suitable for transport vehicles used for orthopedic patients. Background Technology
[0002] For orthopedic patients, the transport vehicle plays a crucial role during surgical procedures. Before surgery begins, patients must be safely transferred from their ward to the operating room using a transport vehicle. This process involves not only the patient's physical movement but also their safety and comfort. After surgery, patients remain on the transport vehicle for at least half an hour in the recovery room. This time is critical as it's the key period for them to awaken from anesthesia and begin to regain consciousness. Only after confirming that the patient's condition is stable and safe to move will they be transferred back to their bed in the ward by the transport vehicle. Throughout this process, patients move almost entirely on the transport vehicle. If the patient has a fracture or has just undergone surgery, the movement could cause secondary injury. Therefore, it is necessary to immobilize the patient's limbs to ensure safety and stability during transport. To address this, we propose a patient transport vehicle. Utility Model Content

The sliding connection design of the memory foam head fixation bracket 7 allows medical staff to flexibly adjust the position of the head bracket according to the patient's height and body shape, ensuring the stability and effectiveness of the fixation. In addition, the chest fixation strap 20 binds the patient's torso to the foam mattress 3, further enhancing the patient's stability during transport. Especially when the patient is unconscious or unable to control their body movements, the chest fixation strap 20 can effectively prevent large-scale movement of the patient's body, ensuring the safety of transport.
[0029] When a patient's leg or foot is injured on one side and requires immobilization, the design of the leg-flipping notch 11 and the switching seat 12 allows the corresponding side of 12 to be flipped, causing the leg immobilization mechanism and foot support immobilization mechanism on that side to face upwards. This immobilizes the patient's leg and foot bones on that side, facilitating necessary examination and care of the patient's leg during transport, while also providing additional support and immobilization. The filling foam block 13 on the switching seat 12 can be flipped upwards when the patient's leg or foot is uninjured, keeping the foam mattress 3 flat relative to the patient's leg position, ensuring comfort during transport for patients without leg or foot injuries. Through innovative modular structure and ergonomic design, this system significantly improves operational efficiency and patient comfort while ensuring transport safety, making it particularly suitable for the precise transport needs of critically ill patients with spinal injuries, pelvic fractures, and other conditions.
