By figure 1 to 4, including bottom plate 1, bottom plate 1 upper end is equipped with cushion 2, the standing groove 3 that has seted up a plurality of along its up end equipartition and link up from top to bottom is seted up on cushion 2, standing groove 3 is upper and lower axial, coaxial sliding connection has slide cartridge 4 in the standing groove 3, slide cartridge 4 upper end is equipped with rather than inside intercommunication and the gasbag 5 of protractile standing groove 3, slide cartridge 4 lower extreme coaxial is equipped with keeps off ring 6, coaxial being equipped with in the slide cartridge 4 rather than the contact of inside edge face and gliding push pedal 7 from top to bottom, push pedal 7 with keep off between the ring 6 through spring 8 be connected.

In order to move the push plate 7 up and down, the lower end of the push plate 7 is coaxially provided with a push column 9, the bottom plate 1 is provided with a sliding plate 10 capable of sliding back and forth, and the push column 9 can slide up and down along with the back and forth sliding of the sliding plate 10.

In order to facilitate the movement of the push pillars 9, the sliding plate 10 is provided with a plurality of guide grooves 11 which correspond to the push pillars 9 one by one and have upward openings, the front end surfaces of the guide grooves 11 are inclined surfaces which are high in the front and low in the rear, the lower ends of the push pillars 9 penetrate through the baffle ring 6 and are rotatably connected with left and right axial rollers 12, and the rollers 12 can be in contact with the inclined surfaces of the guide grooves 11 on the corresponding sides.

In order to facilitate the movement of the sliding plate 10, a sliding groove 13 with an upward opening is formed in the bottom plate 1, the sliding plate 10 is located in the sliding groove 13, a screw rod 14 is connected to the front side of the bottom plate 1 in a threaded manner, the left end of the screw rod 14 is rotatably connected with the sliding plate 10, and a rotating handle 15 is arranged at the right end of the screw rod.

In order to facilitate the use of the device, the upper end of the elastic cushion 2 is provided with an elastic cloth which shields the placing groove 3 and can be contacted with the air bag 5.

In order to limit the sliding of the sliding cylinder 4, the maximum diameter of the baffle ring 6 is larger than the aperture of the placing groove 3, and the baffle ring 6 can contact with the lower end surface of the elastic pad 2.

When the elastic cushion is used, a patient lies on the elastic cloth and is positioned above the elastic cushion 2 and the air bags 5, the air bags 5 are expanded in an initial state, the upper ends of the air bags extend out of the placing grooves 3 on the corresponding sides, the springs 8 are in a stretching state, the body of the patient is in contact with the air bags 5 and the elastic cushion 2, the pressure on the skin of the patient is relieved, and meanwhile, the upper ends of the air bags 5 are not flush with the upper end of the elastic cushion 2, so that the partial pressure on the skin of the patient is different;

when a patient lies on the back for a certain time, the rotating handle 15 is rotated clockwise, the rotating handle 15 drives the screw 14 to rotate clockwise, the screw 14 rotates clockwise and drives the sliding plate 10 to slide forward, at the moment, the roller 12 slides downward along the guide groove 11, under the action of the pulling force of the spring 8, the push plate 7 drives the push post 9 to slide downward, the push post 9 drives the roller 12 to slide downward along the guide groove 11 on the corresponding side, the air bag 5 contracts downward and is contained in the placing groove 3, when the spring 8 is in a balanced state, the relative movement between the push plate 7 and the baffle ring 6 is stopped, at the moment, the push post continues to slide along with the sliding plate 10, due to the self gravity of the sliding cylinder 4, the sliding cylinder 4 drives the baffle ring 6 and the air bag 5 to slide downward, and the push plate 7 drives the push post 9 to continue to slide downward;

when the pushing column 9 drives the roller 12 to contact with the bottom surface of the guide groove 11, the pushing column 9, the baffle and the sliding barrel 4 stop sliding downwards, the air bag 5 is completely accommodated in the placing groove 3, meanwhile, the sliding barrel 4 slides downwards for a certain distance, so that the placing groove 3 leaks out, a patient continuously lies on the elastic cloth, and the pressure part of the skin of the patient contacting with the device is changed;

when a patient lies on the bed for a certain time, the rotating handle 15 is rotated anticlockwise, the rotating handle 15 drives the screw 14 to rotate anticlockwise, the screw 14 drives the sliding plate 10 to move backwards, the sliding plate 10 pushes the roller 12 to slide upwards through the guide groove 11, the roller 12 pushes the push plate 7 to slide upwards through the push post 9, the push plate 7 drives the baffle ring 6 to slide upwards through the spring 8, the baffle ring 6 drives the sliding barrel 4 to slide upwards, when the baffle ring 6 contacts with the lower end face of the elastic cushion 2, the sliding cylinder 4 moves upwards to the limit position, at the moment, the push plate 7 stretches the tension spring and pushes the gas on the upper side in the sliding cylinder 4 upwards along with the continuous upward sliding of the push column 9, so that the air bag 5 is expanded, when the roller 12 contacts with the upper end surface of the sliding plate 10, the device is restored to the initial state, the air bag 5 stretches out of the placing groove 3 again, the rotating handle 15 stops rotating, and the position of the sliding plate 10 cannot be changed due to the self-locking property of threaded connection;

the air bag 5 is repeatedly stretched and expanded, contracted and retracted into the placing groove 3 through the steps, so that the pressure position of the skin of a patient is changed in the process of lying in bed, and the pressure sore of the patient is reduced.

The medical nursing bed is simple in structure and convenient to operate, the air bag, the sliding cylinder and the elastic cushion are arranged, pressure on the skin of a patient when the patient lies in bed for a long time is reduced, the part of the skin of the patient, which is subjected to the pressure, can be changed through expansion and contraction of the air bag, skin pressure sores of the patient are prevented, the comfort level of the patient is improved, nursing and treatment of medical workers on the patient are facilitated, gaps exist between the elastic cloth and the air bag, the air permeability of the device is improved, and the device is convenient for the patient to use.
