When the back-up action is performed, the air cushion 407 in the connecting portion first finishes the air release, and the activity space is released for the small inner air cushion 406 to perform the back-up action along with the back-up bed plate. When the turning-over operation is performed, the air pump 308 works, the first electromagnetic directional valve and the fourth electromagnetic directional valve in the air path are electrified and switched, the second normally closed electromagnetic valve and the fourth normally closed electromagnetic valve are electrified and opened, the air is used for inflating the left turning-over air cushion 409 through the fifth electromagnetic directional valve, and after the fifth electromagnetic directional valve is electrified and switched, the air pump 308 can inflate the right turning-over air cushion 410 to drive a user to complete the left turning-over or right turning-over operation. The left rollover cushion 409 and the right rollover cushion 410 are respectively positioned above the concave outer cushion 402 and are connected to the high shield cushion 404. The air bed in the rollover state is shown in fig. 9 and 10.

When the user bends the legs, the air pump 308 works, the first electromagnetic directional valve and the fourth electromagnetic directional valve are electrified and switched, the third normally closed electromagnetic valve and the fourth normally closed electromagnetic valve are electrified and opened, the air pump 308 inflates the leg bending air cushion 411, and the leg bending air cushion 411 is located on one side of the footboard 10 and used for driving the user to complete the leg bending action. The air bed state at this time is shown in fig. 11.

When a user needs to take a shower in bed, the air pump 308 works, the first electromagnetic directional valve is electrified and switched, the first normally closed electromagnetic valve is electrified and switched, the third electromagnetic directional valve is electrified and switched, air reaches the high-protection air cushion air charging and discharging port through the first electromagnetic directional valve, the first air flow distributor, the first normally closed electromagnetic valve and the third electromagnetic directional valve, the air pump 308 is used for charging the high-protection air cushion 404, and the high-protection air cushion 404 can be used for preventing shower water from splashing around when the user takes the shower, as shown in fig. 12.

At present, a mattress used by a nursing bed is mainly a cotton cushion, although the cotton cushion can relieve the fatigue of people lying in bed for a long time to a certain extent, the situations of uneven stress of the body of a user and unsmooth blood circulation of the local part of the body still exist, and the probability of bedsore occurrence is increased. Compared with a cotton cushion, the air cushion bed can well solve the problem that the stress of a human body lying in bed is uneven, and greatly reduces the risk of bedsores of a person lying in bed for a long time. The general connection of the air cushion bed air passages is shown in fig. 13.

With reference to fig. 14 and 15, the dining table 5 comprises a fixed stop 501, a stop screw 502, an extension rod 503 and a dining table rod 504, wherein:

the fixed stop block 501 is fixed on the bedstead 1 through a fastening bolt and a fastening nut, the upper end surface of the fixed stop block is a semicircular surface, the rotation angle of the telescopic rod 503 around the fixed stop block 501 is realized by adjusting the tightness degree of the stop screw 502, and the maximum rotation angle of the telescopic rod 503 around the fixed stop block 501 is 90 degrees. The telescopic rod 503 and the dining table rod 504 are connected together by a pin shaft, and the dining table rod 504 rotates around the telescopic rod 503 by 90 degrees through the pin shaft. The height of the telescopic rod 503 is adjusted to meet the use requirements of different users. This dining table structure can realize receiving bed frame one side when the user does not use, satisfies the user to the demand in bed space.

In order to realize the intellectualization of the nursing bed control, the invention designs the control system of the nursing bed. The nursing bed is provided with a plurality of control modes; the operating state of the nursing bed is detected by different sensors, and the detection result is fed back to the control system and is displayed by the operation panel. A control system program flow diagram is shown in fig. 16.

The embodiment provides a novel function air cushion nursing bed, aims at realizing the action that the bed person stands up and bends the leg on the left and right side through filling gassing 4 different parts to the accessible is to adjust the demand that satisfies different users with regard to 5 height in dining-table and transfusion rod length with warm water washing, warm braw stoving and the bed shower of collection and warm water washing, warm braw of bed person's stool and urine on the bed. Convenient operation, easy assembly and dismantlement, operation safe and reliable, practicality are strong, can greatly alleviate nursing staff and carry out nursing work's human input, and very big satisfying the long-term bed personnel have the demand of functions such as collection just, washing to the nursing bed.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
