It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be understood that the terms "first", "second", etc. are used herein to describe various information, but the information should not be limited to these terms, and these terms are only used to distinguish one type of information from another. For example, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information, without departing from the scope of the present invention.

As shown in fig. 1 to 4, the utility model discloses a pneumatic suspension mattress 1 of preferred embodiment, including adjusting the air cushion 6, adjusting the air cushion 6 and being equipped with the inflation inlet 8 that links to each other with inflating and deflating the unit, in this embodiment, it is air pump 10 to inflate and deflate the subassembly, air pump 10 passes through trachea 9 with adjusting the air cushion 6 and links to each other, adjust the width direction parallel that is equipped with two banks in the air cushion 6, the bank will adjust the air cushion 6 and separate the chest back regulation part 61 that forms intercommunication each other, buttock regulation part 62 and low limbs regulation part 63, from this when the user stands up or stands up, gas can circulate each other, thereby the person of facilitating the use activity, the atress emergence when also having avoided adjusting the air cushion 6 to stand up or stand up breaks. The volume of the adjusting air cushion 6 is determined to be V after production is completed, the inflation speed of the inflation device is determined to be s, so that the inflation time t can be adjusted and controlled, the inflation pressure in the adjusting air cushion 6 can be adjusted by adjusting the inflation time t, a tiny air pressure sensor or a precise sensor is prevented from being installed on a control air path to control and measure the inflation pressure, and the production cost is reduced.

Based on the technical scheme, by arranging the chest and back adjusting part 61, the hip adjusting part 62 and the lower limb adjusting part 63 which are mutually communicated, when a user lies on the adjusting air cushion 6, when the user turns over or moves the body, the air in the adjusting air cushion 6 can freely move, the adjusting air cushion 6 can change the shape along with the posture conversion of the user and better fit with the user, thereby the stress point between the adjusting air cushion 6 and the user is large, the phenomenon of pressure sore caused by long-time bed rest is avoided, meanwhile, when the user turns over, after the air flows to the side edge of the adjusting air cushion 6, a reaction force is provided for the user to a certain extent, thereby the user is prevented from falling off the bed, further, the volume of the adjusting air cushion 6 is determined after the production is finished, the speed of the inflating device is determined, and the problem of micro air pressure regulation and control can be solved by regulating and controlling the inflating time, the use of a micro air pressure sensor is omitted, and the production cost is reduced.

Furthermore, a plurality of first isolation belts are arranged in the chest and back adjusting part 61 along the length direction of the adjusting air cushion 6, and the first isolation belts divide the chest and back adjusting part 61 into a plurality of chest and back adjusting cavities which are communicated with each other; the inside length direction along adjusting air cushion 6 that is equipped with a plurality of second median of low limbs regulating part 63, the second median separates low limbs regulating part 63 and forms a plurality of low limbs regulation chamber that communicates each other, and the quantity of first median is less than the quantity of second median. From this, the cavity volume in chamber is adjusted to every back of the chest is big than the cavity volume in lower limbs regulation chamber, holds gaseous many, because human main stress point is at head, back, and the cavity volume in chamber is adjusted to the back of the chest is big than the cavity volume in lower limbs regulation chamber for when the user lies on the mattress, the gas in the back of the chest is adjusted the intracavity and is discharged by appropriate amount the back, and the mattress wholly is the leveling state, can not appear unable suspension and the condition of bed board laminating.

Further, a third isolation belt is provided in the middle of the buttocks regulating portion 62, and the third isolation belt divides the buttocks regulating portion 62 to form two buttocks regulating chambers which are communicated with each other. Therefore, the problems that the middle of the adjusting air cushion 6 is bulged when the traditional air cushion bed is inflated, and a user slides down to the two sides of the air cushion bed, so that the use feeling is poor or the danger of falling down is avoided. The provision of the third isolation belt further ensures the safety and comfort of the user.

Preferably, the third isolation belt is positioned in the middle of the inflation channel of the hip adjusting part 62 communicated with the chest and back adjusting part 61, thereby avoiding that one side is pressed too high and the other side of the air bag protrudes when the patient turns over, and keeping the balance of the left and right air bags. In this embodiment, the length of the position of the air-filled channel in which the hip adjusting part 62 communicates with the thorax adjusting part 61 is adjusted according to the age of the person, and the position thereof is located at the position corresponding to the coccyx when the user lies on the adjusting mattress 6. Which is located along the length of the air mattress 6 from the end of the thorax portion 61 to the hip portion 62 approximately 1/3-1/2 of the air mattress 6. Thus, the position of the third isolation belt corresponds to the anatomical form of the human body, so that the user can lie on the adjusting air cushion 6 more comfortably.

In this embodiment, the number of the first isolation belts is 2, and the number of the second isolation belts is 3. The buttock has a cavity, the shank is equipped with four cavities, because human structural feature, human main weight distributes at buttock to head position, the people crouches on the gasbag, the big position gasbag undercut height of bearing can be bigger, consequently, three cavities of head one side design and four cavities of shank design, make the volume of each cavity can not be too little, thereby the phenomenon that the user can't suspend when having avoided the cavity volume undersize, design like this simultaneously and make the cavity of head one side be greater than the cavity of shank, guarantee that the human state of lying in bed can suspend completely and keep the gasbag balanced down.

Preferably, a mounting pad 7 is also included, which is disposed below the conditioner air mattress 6. Therefore, the installation of the adjusting air cushion 6 is convenient, the direct contact of the adjusting air cushion 6 with the bed board is avoided, and the damage of the adjusting air cushion 6 is avoided.
