Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary devices, in particular to a novel medical transport device. Background Art

[0002] In view of the current problem of "difficult transportation" in hospital surgical examinations, a new type of medical transportation device has been designed to solve the defects of manual transportation that easily causes secondary injuries, the difficulty in standardizing the transportation process, the limited adaptation scenarios, the high labor intensity and low efficiency of medical staff. The transportation device is mainly used in hospitals and is a medical auxiliary device that can help patients transfer between beds and operating tables, CT machines and other devices. At present, many scientific research institutions are studying such devices, such as a human body transfer device and transfer method suitable for hospitals with application number 202110288667.6. Although the device can realize transfer by means of hooks staggered on both sides, the hooks will squeeze and rub against the patient's body during operation, which may easily cause secondary injuries; such as a medical transfer flatbed with application number 202223239537.2. The transfer bed can cooperate with accompanying personnel to realize transfer work, but it still requires multiple people to lift and move it to realize transfer, which fails to effectively reduce the difficulty of nursing; such as a patient transfer device for hospitals with application number 202220042571.1. Although the device can realize transfer, it is easy to roll over due to the heavy load on one side during the transfer process, and no safety braking system is introduced during the transportation of patients, which may easily cause safety hazards. In addition, the device still requires manpower to drive the transfer device to complete the transportation process after transfer, which fails to effectively improve the safety and efficiency of transfer between multiple scenes in the hospital.

[0003] The above-mentioned transfer devices lack the ability to handle transfers between beds and operating tables, CT machines and other devices, and lack safety performance during the transfer process; and most of the transfer devices have a low degree of automation, which fails to reduce the difficulty of care for accompanying personnel. Therefore, a medical transfer device is designed to meet the needs of safe and efficient transfers between multiple scenes in the hospital, effectively avoid secondary injuries to patients, reduce the difficulty of care for accompanying personnel, greatly improve the work efficiency of medical institutions, and contribute to the improvement of my country's medical modernization level.
