Description
Technical Field
The utility model relates to a portable full-automatic body-turning nursing mattress, in particular to a portable full-automatic body-turning nursing mattress which consists of a base pad, a body-turning frame group, a body-turning air chamber, an air pump and a control system.
Background
In clinical and home care practices in hospitals, many patients cannot get up and turn over automatically for a long time due to disease and body weakness, and the condition causes muscle and bone pain of the patients, bedsores, pneumonia caused by sputum deposition and various pulmonary complications. Regularly help the patient to stand up through manual mode not only consumes a large amount of energy and physical power of medical personnel, but also probably causes muscle damage to patient and nursing staff itself, and the nursing air mattress that various help patients carry out the bed and stand up or other activities from this is born at the same time. At present, the method is mainly divided into two categories: one is that all air bags at the bottom of the air mattress are filled with air in advance, then the corresponding parts of the human body are deflated to realize the side turning of the human body in a way that the corresponding parts of the human body hang down passively, the product is usually composed of a base cushion and strip-shaped air bags which are arranged in sequence, for example, the air mattress special for ACS TURN hospital of Kunshan Yabao medical instruments company, which can be folded, rolled and carried conveniently, but can not turn over at a large angle quickly as required, a turning-over process needs several minutes, the turning-over angle is only within 30 degrees, because the air mattress needs to use a blower air pump with high power, large flow and lower pressure with the air flow rate of nearly kiloliter per minute, therefore, the noise is high, the human body can slide to the inner side wall of the air mattress guardrail in the side-tipping state, and when the human body is lifted from the side-tipping state to be flat, the human body side and the inner side wall of the air mattress guardrail can generate extrusion discomfort; another kind of air mattress and the utility model discloses there is more similar structure, the installation under the layer board of human corresponding part under the mattress stands up the gasbag, the action of standing up is realized lifting up or putting down the human body voluntarily through the inflation of gasbag, gassing, for example, US 8,776,290B 2 that US patent office 2014 7/15/A published, this kind of product also helps the patient in bed to stand up through the installation back of simpler mode, this kind of product adopts the little power usually, the atmospheric pressure is slightly higher, the gas flow is tens of liters per minute, but because the structure limitation, the same existence can't realize big angle as required, stand up fast, unless adopting high-power, large-traffic air pump and large capacity gasbag, and because can't realize wholly standing up, can make patient's back produce unsettled sense in the process of standing up, in addition, these two kinds of products do not possess the function of independently rising up the back, bend the leg, need rely on the bed that has the function of rising the back of bending the back, The leg is bent.
