Description

Back lifting mechanism of nursing bed

Technical Field

The invention relates to the technical field of nursing beds, in particular to a back lifting mechanism of a nursing bed.

Background

With the development of science and technology, medical instruments are continuously updated and changed, nursing beds are also subject to one-generation and one-generation innovation, the existing nursing beds are generally power beds and are divided into electric or manual nursing beds which are developed and researched according to the bedridden life habits and treatment needs of patients, and for the bedridden patients, especially for the patients with poor self-care capability or no self-care capability, the nursing beds need to meet the daily activities of rising and lifting the back, lifting legs and putting legs, excreting and the like of the patients.

The back lifting mechanism of the prior nursing bed is generally formed by hinging two bed boards, when the back lifting action is carried out, the driving mechanism jacks up the bed board opposite to the upper body, so that a patient lying down slowly lifts up, in the rising process, because the human body takes the position of the hip as a rotating fulcrum and the back rising mechanism takes the hinged part of the two bed boards as a rotating fulcrum, the distance from the hip to the hinged part of the two bed boards is generally kept unchanged in the rising process of the human body, if the position of the contact point of the back and the bed boards is involuntarily adjusted by a patient, the back of the human body can be subjected to downward extrusion force from the bed boards along with the gradual reduction of the included angle between the two bed boards, and the use comfort degree of the patient with poor driving force is lower, under the action of the squeezing force, the chest part of the patient is easy to be pressed, and the chest part of the patient is potentially dangerous for the patient with special disease.

Therefore, the existing back rising mechanism of the nursing bed has the problems that the back of a user is easily squeezed downwards, so that the chest is oppressed, the use comfort is poor, and certain potential danger exists.
