Description

Technical Field

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

[0002] As the elderly population continues to grow, the demand for care for bedridden disabled and disabled elderly people is also gradually increasing. During the care process, medical staff will inevitably need to help patients complete the transfer between different scenarios. Therefore, more and more researchers want to use mechanical devices to assist medical staff in completing the heavy work of transfer and nursing, and medical transfer devices have emerged. The devices are mainly used in hospitals. They are designed to safely and effectively transfer patients, especially those in critical conditions, fractures, coma, etc., and critically ill patients who need to be transferred in multiple places such as beds, CT machines, and operating tables. At present, there are many such devices, such as a semi-automatic transfer vehicle for bedridden patients with application number 202121980690.3. Although the device can automatically place the patient on the bed and the testing platform at the same time, it is easy to tip over due to the heavy load on one side during the transfer process, and it is difficult to achieve transfer in different scenes due to its large size; such as a human transfer device and transfer method suitable for hospitals with application number 202110288667.6. The device uses hooks arranged alternately on both sides to achieve transfer, but the hooks will squeeze and rub against the patient's body during work, which can easily cause secondary injuries; such as a medical transfer and nursing robot with application number 201911142064.4. The device completes the transfer of patients between different beds by driving the bed board. Although the device has a simple structure and is easy to use, it cannot meet the perception needs of the surrounding environment during multi-scene transfer, and cannot meet the transfer needs in CT examination rooms and MRI examination rooms.

[0003] The above-mentioned transfer devices not only fail to meet the transfer needs of critically ill patients in multiple places such as beds, CT machines, operating tables, etc., but also fail to guarantee the safety of intra-hospital transfer. Critically ill patients are extremely vulnerable to secondary injuries during the transfer process. Therefore, it is particularly important to design a qualified and comfortable transfer device that meets the requirements of patients. Among them, meeting the special requirements of patients in different body postures during the transfer process, improving the safety of the transfer process of critically ill patients, meeting the transfer needs of clinical critically ill patients, and reducing the difficulty of nursing for medical staff and improving the efficiency of transfer work are the key requirements for designing medical patient transfer devices.

[0040] The accompanying staff moves the transfer bed to the room where the patient is located, confirms that the foldable transfer bed board 3 is in a folded and falling state, operates the controller to retract the lifting and telescopic rod 43, lifts the lifting rod 42 and the lifting and telescopic rod 43, confirms that the transfer mattress 5 is arranged directly under the patient's body, adjusts the width of the laterally retractable driving chassis 2 to be larger than the width of the patient's bed, pushes the transfer bed vertically to directly above the patient, presses the universal wheel locking mechanism 25 to prevent the transfer device from moving, and completes the preparations before transfer.

[0041] The accompanying staff operates the controller to drive the four-bar linkage 1 8a and the four-bar linkage 2 8b on both sides to move through the servo motor 1 13a and the servo motor 2 13b, thereby controlling the height of the lifting mechanism 2, so that the height of the foldable transfer bed board 3 connected to the upper load-bearing frame 6 is flush with the height of the patient, preventing the patient from feeling uncomfortable during transfer.

[0042] At this time, the lifting mechanism 4 for lifting the patient is located directly above the transfer mattress 5. The accompanying personnel operates the controller to rotate the four screw rods 32 through the four lifting mechanism motors 31 on both sides, and adjust the positions of the four screw nuts 33 to make them descend. At the same time, the support rods I 34 and II 35 installed on the screw nuts 33 descend accordingly, and the support rods I 34 and II 35 stop when they are close to the height of the patient.

[0043] The accompanying staff manually inserts the steel rings around the transfer mattress 5 into the anti-detachment hooks 36 of the lifting mechanism 4 used to lift the patient, and confirms that the anti-detachment hooks 36 are firmly connected to the steel rings. The accompanying staff operates the controller to rotate the four screw rods 32 through the four lifting mechanism motors 31 on both sides, and adjusts the positions of the four screw nuts 33 to make them rise. At the same time, the support rods I 34 and II 35 installed on the screw nuts 33 rise accordingly, driving the transfer mattress 5 locked by the anti-detachment hooks 36 on the support rods I 34 and II 35 to rise. At the same time, by adjusting the width of the laterally retractable driving chassis 2, the transfer mattress 6 under the patient is stretched and tightened, thereby lifting the patient smoothly off the bed surface.

[0044] The accompanying staff releases the universal wheel locking mechanism 25 to drive the transfer equipment, and pushes the patient backward from the top of the hospital bed through the transfer mattress 5 located on the lifting mechanism 4 for lifting the patient, and places the patient in an open space, and lifts the transfer bed board Ⅰ26 and the transfer bed board Ⅱ27 through the foldable tripod Ⅰ28 and the foldable tripod Ⅱ29. The accompanying staff operates the controller, rotates the four screw rods 32 through the four lifting mechanism motors 31 on both sides, adjusts the positions of the four screw nuts 33 to make them descend, and at the same time, the support rods Ⅰ34 and Ⅱ35 installed on the screw nuts 33 descend accordingly, driving the transfer mattress 5 locked by the anti-detachment hooks 36 on the support rods Ⅰ34 and Ⅱ35 to descend, and finally puts the transfer mattress 5 on the foldable transfer bed board 3, adjusts the width of the transversely retractable driving chassis 2 to align the transfer bed board Ⅰ26 and the transfer bed board Ⅱ27, and operates the controller to make the lifting rod 42 and the lifting telescopic rod 43 fall, and the lifting telescopic rod 43 extends out and cooperates with the lifting rod 42 to improve the stability of the transfer equipment. By operating the controller to drive the transfer device, the patient can be transferred between different departments. At this point, the accompanying staff has successfully moved the patient to the transfer device.

[0045] In addition, when the transfer device is not working, the foldable transfer bed plate 3 can be folded, and the width of the transfer device can be minimized by adjusting the transversely retractable driving chassis 2, while reducing the overall height of the transfer device, thereby reducing the storage space of the device.

[0046] The steps for moving a patient from a transport device to another location are substantially the same as those described above and will not be described in detail.

[0047] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model and are not limited to the embodiments shown herein.
