Description

Technical Field

[0001] The utility model relates to the technical field of nursing equipment, in particular to the field of nursing beds, and specifically refers to a multifunctional wheelchair nursing bed. Background Art

[0002] With the advancement of medical technology and the increasing trend of population aging, nursing beds, as an important medical care equipment, have been widely used in the field of medical care.

[0003] Traditional nursing beds have many inconveniences in use. For example, when patients with limited mobility need to go out for examination or relaxation, caregivers are required to manually transfer them from the nursing bed to a wheelchair. This process is not only time-consuming and labor-intensive, but also easy to cause unnecessary harm to the patient during the transfer process.

[0004] In addition, in order to prevent patients from having various problems such as back sores and muscle atrophy due to long-term bed rest, it is necessary to frequently turn the patient's body from a supine position to a side-lying position, so that the nursing staff can wipe, clean, massage and other nursing work on the patient's body. Since most patients who have been bedridden for a long time have difficulty in moving, they need the assistance of nursing staff when turning their bodies, which undoubtedly increases the labor intensity of nursing staff. Especially when seriously ill patients turn over, not only do they need to turn the patient's body, but they also need to prevent various medical supplies such as tubes and needles on the patient from falling or bending in time during the turning process. However, when turning the patient's body, nursing staff often need to use both hands, so it requires the cooperation of multiple nursing staff, which undoubtedly increases the cost of patient care. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a multifunctional wheelchair nursing bed which can reduce the labor intensity of nursing staff and the nursing cost of patients.

[0006] The utility model is realized through the following technical scheme, and provides a multifunctional wheelchair nursing bed, comprising an outer bed body and a wheelchair mechanism, wherein the outer bed body is provided with a first bed frame component and a second bed frame component, the wheelchair mechanism is located between the first bed frame component and the second bed frame component, the wheelchair mechanism is connected to the outer bed body through a locking assembly, the outer bed body is provided with an opening, and the wheelchair mechanism comprises a central frame and a head and back flip assembly, a lower limb flip assembly, a side flip assembly, and a flip plate assembly arranged on the central frame.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] Firstly, through the head and back flipping assembly and the lower limb flipping assembly, the wheelchair mechanism can realize the switching between the sitting position and the lying position according to the needs of the patient, and the locking assembly can conveniently and quickly realize the connection and separation between the wheelchair mechanism and the peripheral bed body. Therefore, the patient does not need to transfer and can use the wheelchair mechanism to travel, which greatly reduces the labor intensity of the nursing staff and avoids the possible harm to the patient when the patient is manually transferred from the nursing bed to the wheelchair. In addition, since the wheelchair mechanism is located between the first bed frame component and the second bed frame component, this design does not require the patient to move on the nursing bed, and can turn the patient from the lying position to the sitting position in the original position. Compared with the design of setting the wheelchair mechanism on one side of the nursing bed, it can further reduce the labor intensity of the nursing staff, avoid the possible harm to the patient when the nursing bed is moved horizontally, and is more conducive to the travel of patients with limited mobility.

[0009] Secondly, the outer bed body can ensure the overall width of the nursing bed, avoiding the patient's inability to lie comfortably due to insufficient width of the wheelchair;

[0010] Thirdly, when the nursing staff is wiping, cleaning, massaging and other nursing work on the patient's body, the side-turning component can be used to conveniently turn the patient from a supine position to a side-turning position without the need for manual turning by the nursing staff, thereby reducing the labor intensity of the nursing staff.
