Description

Nursing sickbed with turning function and using method thereof

Technical Field

The invention relates to the technical field of nursing equipment, in particular to a nursing sickbed with a turning-over function and a using method thereof.

Background

In the hospital, there are many stupor, hemiplegia, severe patients, bone injury patient and other long-term bed-ridden patients, if can not turn over for them on time, the tissue is compressed for a long time, blood circulation is obstructed and causes the tissue anoxia, just lead to cell death, can lead to the health to suffer from bedsore, it is very painful, the sick bed is the supplementary medical care equipment that the application volume is great among the medical instrument, play important effect to patient's medical rehabilitation, along with the improvement of medical care level, the sick bed is also improving constantly, the difficulty that patient exists when standing up, stool and urine has been solved in its purpose, patient's pain in the in-process of turning up has been alleviateed on the one hand, on the other hand can also alleviate nursing staff's intensity of labour.

For example, in the patent application with publication number CN110151434A, a hospital bed for assisting a critically ill patient to turn over and lean on his side is disclosed, which comprises a bed board; the bed plate comprises a fixed plate and a turnover plate hinged with the fixed plate, the lower end of the turnover plate is fixedly connected with an arc-shaped rod, a rack is carved on the surface of the arc-shaped rod, the arc-shaped rod is meshed with a driving device for driving the turnover plate to turn over, and the driving device is fixed on the lower side of the bed plate through bolts; the bed board upside both ends are fixed with the bandage, fix with rivet is passed through at the bed board upper end to bandage one end, the bandage other end is connected with wind, wind passes through the bolt fastening at the bed body downside, drive arrangement is provided with the motor, the motor passes through the bolt fastening in the backup pad, the backup pad passes through down tube welded fastening at the stand inboard, motor output shaft rigid connection has circular gear, circular gear and arc pole joggle, the arc pole rotates and is connected with fixed bent lever. Above-mentioned sick bed is when the help patient stands up, on arranging the returning face plate on the bed board with the patient, the motor drives circular gear and rotates, and circular gear drives the arc pole and slides on fixed curved bar, and the arc pole upper end is carried out gradual upset with the returning face plate, overturns severe patient to the fixed plate on to reach the effect of standing up. Such a bed presents the following problems when turning over a patient: 1. this sick bed is when standing up the patient, and the patient lies flat completely on the returning face plate, then rotates around its and fixed plate articulated position through the returning face plate and makes the patient turn over to the fixed plate on to this reaches the effect of standing up, and this kind of mode of standing up is stiff and straight rotates the fixed plate from the returning face plate with the patient on, can increase the uncomfortable sense of patient when standing up like this. 2. When a patient in the sickbed turns over, the maximum turning angle is 90 degrees, when the turning plate rotates to 90 degrees, the patient vertically falls onto the fixed plate from the turning plate, and the patient can be injured seriously by the turning mode.

Disclosure of Invention

Aiming at the defects in the prior art, the technical problems to be solved by the invention are as follows: how to provide a nursing sickbed with a turning-over function, which can reduce the uncomfortable feeling brought to a patient in the turning-over process and simultaneously avoid the additional injury caused by the vertical falling of the patient.
