The flexible pressure-sensitive sensor 2 can judge the breathing state of a user, when the breathing state of the user detected by the flexible pressure-sensitive sensor 2 is an apnea state, the height to which the air bag to be inflated or deflated needs to reach is determined according to the pressure area of the sleeping posture of the patient measured by the flexible pressure-sensitive sensor 2 and the pressure value of each area, the inflation amount or deflation amount required by each air bag is judged, and finally the two-position three-way electromagnetic valve and the corresponding micro electromagnetic valve are controlled by the controller to inflate and deflate the air bag, so that the sleeping posture of the user is changed.
The working principle of the invention is as follows: the display screen of the operation panel 6 displays the sleeping posture, breathing and pressure distribution of the user. According to the weight of the user, a weight button is pressed to a position corresponding to the weight of the user. Under normal conditions, the curve of human breathing is a sinusoidal curve. When the automatic button is pressed down, when the controller detects that the breathing curve of a user is in a gentle state, the specific coordinate position of the air bag unit needing to be operated is determined according to the pressure distribution of the sleeping posture of the user, the miniature electromagnetic valve 8 and the two-position three-way electromagnetic valve 10 which control the corresponding air bag are automatically opened, the corresponding air bag is inflated or deflated by the inflator pump 11, the height of the air bag is wavy, and finally the sleeping posture of the human body is changed. When the manual button is pressed, the corresponding button is manually pressed to realize the transformation of the human body pose according to the requirement of a user. If the user is a patient lying in bed for a long time, the bedsore is prevented, and the timing button is pressed, so that the air bag unit array can be inflated or deflated within a certain time, and the blood circulation of the patient is promoted. The hardness of the bed can be adjusted according to personal preference.

the air bag module comprises an air bag, an air cushion, a branch rubber air pipe, a first air storage tank, a second air storage tank and an inflating pump; 80 air bags form an air bag unit array, the 80 air bags are arranged on the base fabric in an 8x10 array form, the size of each air bag is 100mmx100mm, and each air bag is divided into an upper layer and a lower layer; the air tap of each air bag is connected with a branch rubber air pipe, the branch rubber air pipes of two adjacent air bags are connected through a T-shaped interface, then connected with a micro electromagnetic valve and communicated with a main rubber air pipe through a conversion interface; the air bags in the rows 1 to 4 are called as the part A, the air bags in the rows 5 to 8 are called as the part B, and branch rubber air pipes of the air bags in the part A are communicated with a main rubber air pipe through a conversion interface to form a main air passage A; the air path of the part B is the same as that of the part A, namely a branch rubber air pipe of the part B air bag is communicated with the micro electromagnetic valve through a conversion interface and another main rubber air pipe to form a main air path B; the inlets of the main gas path A and the main gas path B are respectively connected with a two-position three-way electromagnetic valve, and the two-position three-way electromagnetic valves respectively control the inflation and deflation of the main gas path A and the main gas path B; inlets of the main air path A and the main air path B are communicated with a first air storage tank through corresponding two-position three-way electromagnetic valves through T-shaped interfaces, and the main air path A and the main air path B are communicated with a second air storage tank through corresponding two-position three-way electromagnetic valves through T-shaped interfaces; a first pressure transmitter and a second pressure transmitter are respectively arranged on the first air storage tank and the second air storage tank, the two pressure transmitters are used for detecting the pressure inside the air bag unit array, in order to prevent the air bag inflation quantity from exceeding the maximum value allowed by the air bag, the first pressure transmitter 13 is used for detecting the pressure inside the air bag after the air bag is inflated, and the second pressure transmitter 15 is used for detecting the pressure inside the air bag after the air bag is deflated; the first air storage tank is connected with the inflator pump, and the second air storage tank is communicated with the outside air; the air bag unit array is arranged in the middle of the air cushion in a surrounding mode, the air cushion is connected with the main air passage A and is arranged on the base cloth, the distance from one end of the air bag unit array to the bed head is 1/6-1/4 of the overall size of the mattress, and the distances from the two sides of the air bag unit array to the bed edge are equal; the connection method of the two-position three-way electromagnetic valve is that when the coil is electrified, the inflation state is realized, and when the coil is powered off, the deflation state is realized;
the flexible pressure-sensitive sensor module consists of 80 flexible pressure-sensitive sensors and is used for detecting the respiratory state, the sleeping posture and the sleeping posture pressure distribution of a human body, and each flexible pressure-sensitive sensor is flatly laid on one air bag mattress; 80 flexible pressure-sensitive sensors are flatly laid on the air bag unit array and are calibrated with the air bag unit array, namely the positions of all parts of the body of a user are detected through the flexible pressure-sensitive sensors, and the position corresponding to a mattress is found out, so that the specific coordinate position of the air bag unit array needing to be operated is determined; according to the pressure area of the sleeping posture of the patient measured by the flexible pressure-sensitive sensor and the pressure value of each area, determining the height to which the air bag to be inflated or deflated needs to reach, judging the inflation amount or deflation amount required by each air bag, and finally controlling the two-position three-way electromagnetic valve and the corresponding miniature electromagnetic valve to inflate and deflate the air bag through the controller, so as to realize the sleeping posture conversion of the user;
the controller module comprises a controller, a control box and an operation panel; the controller comprises a serial port relay module and an industrial personal computer, wherein the serial port relay module is respectively connected with the industrial personal computer, two-position three-way electromagnetic valves and 40 miniature electromagnetic valves; the industrial computer is connected to the operation panel through the connecting wire simultaneously, carries out corresponding action through operation panel control serial port relay module, and the industrial computer carries out the communication with first pressure transmitter and second pressure transmitter.
2. The automatic turn-over airbag nursing mattress as claimed in claim 1, wherein the operation panel is provided with a display screen, an automatic button, a manual button, a weight button, a left turn-over button, a right turn-over button and a timing button.
3. The automatic turn-over airbag nursing mattress of claim 1, characterized in that the size of the automatic turn-over airbag nursing mattress is: the width is 1000mm and the length is 2000 mm.
