Description

Technical Field

[0001] The 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 the development of society, the spectrum of diseases has changed significantly, resulting in an increase in the number of patients who need long-term hospitalization and rehabilitation care. More and more patients need to frequently transfer between different departments and different examination equipment during their medical treatment to complete various examinations, treatments and rehabilitation projects, which greatly increases the frequency and difficulty of patient transfers. At the same time, hospitals generally have a relatively insufficient number of medical staff. Faced with an increasing number of patients, medical staff often have to undertake heavy tasks and face difficulties and demands in patient transfers. It is precisely based on these complex factors that the problem of patient transfers in hospitals has become an important medical link that needs to be focused on and resolved.

[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 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 with 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 always stand on the base with his own support. 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 are inconvenient to move. Summary of the invention

At the same time, the first drive motor of the head support device, the hip support device and the leg support device is controlled to make the transfer board bend at a smaller angle to form a structure with an arc to prevent the patient from slipping. The control module controls the mobile device to start moving. When it reaches the designated position or above the designated device, the control module controls the mobile device to stop moving. At the same time, the first lifting device and the second lifting device are controlled to move up and down to the designated position or the height of the designated device, and then the head support device, the hip support device and the leg support device are controlled to rotate so that all the transfer boards are flush with the plane where the designated position or the designated device is located.
