Technical Field
[0001] The present invention belongs to the field of medical auxiliary equipment, and in particular to a posture-changing transport robot for transfer scenarios. Background Art
[0002] With social development, the spectrum of diseases has significantly shifted, leading to an increase in patients requiring long-term hospitalization and rehabilitation care. During their medical treatment, more and more patients are frequently transferred between different departments and examination equipment to complete various examinations, treatments, and rehabilitation programs. This significantly increases the frequency and difficulty of patient transfers. At the same time, hospitals are generally facing a relative shortage of medical staff. Faced with an increasing number of patients, medical staff often face heavy workloads, creating difficulties and demands in patient transfers. It is precisely because of these complex factors that the issue of patient transfers in hospitals has become a critical medical aspect that requires focused attention and resolution.
[0003] The traditional way of transferring patients is mainly through manual handling. Depending on the patient's condition, a single-person auxiliary transfer tool is used to provide assistance, or multiple medical staff are required to collaborate to complete the transfer, which increases the labor intensity of medical staff. With the rapid development of artificial intelligence, the application scenarios and service models of intelligent service robots based on artificial intelligence technology are also constantly expanding. The Chinese invention patent application number 201380076990.0 discloses a nursing robot with a carrying function. The robot is mainly composed of a holding part, a base, a body support part, and an information acquisition device. When carrying the user, the robot hugs the user's armpits and requires the user to rely on his or her own support to always stand on the base. It is not suitable for users who cannot provide greater support themselves, such as users with weak legs or feet or damaged lower limbs who have difficulty in moving. Summary of the Invention

The first drive motor drives the first transmission assembly, the second transmission assembly, the third transmission assembly and the transmission gear 46 to move, so that a certain angle of bending is generated between the transfer boards. When it is necessary to transfer a patient, the bending angle is smaller, so that all the transfer boards form a curved structure as a whole, so that the patient is in a comfortable posture and can prevent the patient from accidentally slipping; when it is not necessary to transfer the patient, the transfer boards are folded to reduce the storage space.

Based on the patient's behavioral intentions, the control module controls the fifth drive motor 26 to adjust the angles of the head support, hip support, and leg support to position the patient at a comfortable angle. At the same time, the control module controls the first drive motors of the head support, hip support, and leg support to make the transfer boards bend at a smaller angle, forming a curved structure to prevent the patient from slipping. The control module controls the mobile device to start moving. When it reaches a designated position or above a designated device, the control module controls the mobile device to stop moving. At the same time, the control module controls the first lifting device and the second lifting device to move up and down to the designated position or the height of the designated device. Then, the control module controls the head support, hip support, and leg support to rotate so that all transfer boards are flush with the plane of the designated position or the designated device. Then, the control module controls the first drive motor to adjust the bending angle between the transfer boards so that each transfer board is flush, facilitating the transfer of the patient from the transfer board. The control module controls the movement of the mobile device away from the patient, slowly withdrawing the head support, hip support, and leg support from beneath the patient to complete the patient's transfer. Throughout the entire movement process, the status of the posture-changing transfer robot and the patient's condition are displayed on a monitor for easy observation. When the patient does not need to be transferred, the control module controls the first drive motor, driving the first, second, and third transmission assemblies and transmission gear 46, causing the transfer board to fold together, reducing storage space.
