It relates to a mechanical patient transfer chair with a safety topology. The invention is particularly useful for postoperative patient mobilization and patient transfer in intensive care units. and an advanced mechanical system developed for use in orthopedic rehabilitation processes. It includes patient transfer chair systems. Current technology uses wheelchairs or 15 patient lifts, controlled lateral transfer, energy independence and advanced safety mechanisms. The inability to offer these services together poses significant risks to patient and staff safety. It consists of a chair positioned on a main frame. a seating surface and, beneath this seating surface, controlled linear movement to the right or left. It includes a lateral sliding platform capable of this movement. This lateral movement is achieved via a linear slide or 20 This is achieved via a telescopic rail system, which controls the speed of movement and sudden changes. It operates in conjunction with a gas spring mechanism that prevents accelerations. The fundamental distinguishing feature of the invention is... Its distinguishing feature is a mechanically and energy-independent, multi-layered secure stop lock. This is a topology.

It eliminates the risks of interruptions and electronic malfunctions. 35 2 PREVIOUS TECHNIQUE In the field of current patient transfer systems and medical assistive devices, especially in surgery post-patient mobilization, patient transfer in intensive care units, and orthopedic procedures. Current solutions used in rehabilitation processes, patient and healthcare personnel safety. It has significant shortcomings and limitations in this regard. In the known technique, patient transfer takes 5 minutes. These typically include wheelchairs, manual transfer boards, electric patient lifts, and ergonomic devices. This is accomplished through various systems such as wheelchairs. Wheelchairs, Controlled lateral transfer allows the patient to be moved from one point to another. He is completely incapable of moving from the bed to the chair or from the chair to the bed. during which time it is only possible to move it manually and usually with the help of more than one person. 10 This situation poses a serious musculoskeletal risk for both patients and staff. This poses a risk of injury. Manual transfer boards slide between the patient and the bed. Although these systems attempt to facilitate transfer by providing a surface, they are entirely user-friendly. It relies on force and cannot minimize the risk of slipping and falling, and also has high friction. Due to its coefficient, it causes shear injuries to the patient's skin during transfer. 15 This is possible. Electric patient lifts and upright lifting systems offer vertical movement capabilities. It provides support and helps the patient stand or sit, but lateral It can be subjected to uncontrolled oscillations in any direction and, due to energy dependence, in emergency situations. or it becomes inoperable during power outages. Current chair systems in known technology are designed with ergonomic comfort in mind. and do not adequately meet medical safety requirements. These systems endanger the patient's health. an effective mechanical locking mechanism to prevent it from falling or slipping during transfer Because it does not involve rotation, it is particularly necessary for patients after knee and hip surgery. This creates stress in the surgical area and negatively affects the healing process. 25 This has an impact. Furthermore, current transfer systems cause uncontrolled movements during transfers. This can occur as a result of a sudden shift in the patient's weight within the system. It can become unstable and cause injuries to the patient. A single health These systems make it nearly impossible for personnel to carry out safe transfers. Intensive care units with limited staff and night shifts face serious operational challenges. This causes difficulties. In electrical systems, battery failures and motor overheating can occur. overloads and errors occurring in electronic control units, sudden changes during transfer This can lead to sudden stops or uncontrolled acceleration, jeopardizing patient safety. Furthermore, the energy dependence of these systems means that in the event of a power outage, emergency situations can occur in healthcare facilities. This causes disruptions to evacuation and patient transfer operations. 35 3 Another significant shortcoming of the current technique is the lack of safety measures for both patients and healthcare personnel during transfer. The ergonomic risks are being ignored. Healthcare personnel are improperly performing manual transfers. Due to body mechanics, they can be exposed to occupational diseases such as lumbar and thoracic disc herniation. This situation threatens both the health of personnel and leads to workforce loss in healthcare institutions. This opens up. However, the sudden movements the patient is subjected to during positioning 5 and unbalanced loading can lead to trauma in the surgical area, muscle spasms, and decubitus ulcers. This lays the groundwork for its formation. All these problems exist in none of the known systems in technology. Controlled lateral movement, mechanical safety stop system, weight sensing-based automatic operation. This is due to the fact that locking and power-independent operation features are not offered together. This situation creates serious security vulnerabilities and operational difficulties in patient transfer. It creates. This invention takes into account all the limitations and shortcomings in the known art. It has been improved and features located under the seating surface, which are not found in any of the existing systems. 15 positioned lateral sliding platform, provided by linear slide or telescopic rail system.

With its two-stage locks, it prevents the transfer movement if a single lock is opened incorrectly. Safety check, when user control is abandoned, when an unbalanced load occurs, or when movement occurs. A safety stop system automatically activates and restricts movement when resistance increases. equipped with a mechanical obstacle detection mechanism and a cam or friction-based mechanical obstacle detection system. It presents an innovative patient transfer chair. The invention eliminates energy dependence in known technology. inadequate safety mechanisms, staff and patient ergonomics issues, uncontrolled lateral movement 25 Fundamental problems such as lack of movement and automatic locking are addressed by a fully mechanical and energy-efficient system.
