The following specific examples are intended to be illustrative of the utility model and are not intended to be limiting, as modifications of the utility model will be apparent to those skilled in the art upon reading the specification without inventive contribution thereto, and are intended to be protected by the patent law within the scope of the appended claims.

The utility model relates to an inflatable mattress capable of adjusting lying postures, which comprises a base plate 1, a turning-over air bag 2 arranged on the base plate 1 and a supporting air bag 3 arranged on the turning-over air bag 2, wherein the supporting air bags 3 are cylindrical and are arranged along the direction vertical to the axial direction of the supporting air bag 3, the supporting air bag 3 is arranged to form a whole layer for supporting a patient, the patient is laid on the whole layer formed by the supporting air bags 3, and the turning-over air bag 2 pushes the supporting air bag 3 to rise through inflation of different parts, so that the turning-over of the patient is supported in multiple directions, and the mode is consistent with the prior art. The support air bags 3 are cylindrical, which is common in the prior art, and the same is true in the present embodiment, and each support air bag 3 may be divided into two cylinders along the axial direction, so as to facilitate the transverse turning over. The supporting air bags 3 are arranged continuously in the prior art, so that the patient is well supported; in this embodiment, a plurality of pairs of adjacent supporting air bags 3 are spaced to form a transverse channel 4 with an extension direction consistent with the axial direction of the supporting air bags 3, a limit sliding block 5 higher than the supporting air bags 3 is arranged in the transverse channel 4, a driving device 6 connected with the limit sliding block 5 is fixed on the turning air bags 2, and the driving device 6 can push the limit sliding block 5 to move along the transverse channel 4; when a patient lies on the inflatable mattress, the front-back direction of the patient from head to foot is consistent with the arrangement direction of the supporting air bags 3, the inflatable mattress is in direct contact with and supports the body of the patient through the supporting air bags 3, and the limit sliding blocks 5 are higher than the supporting air bags 3, so that when the patient slides axially along the supporting air bags 3 in the supporting air bags 3, the limit sliding blocks 5 can block the body of the patient, so that obvious relative sliding between the body of the patient and the supporting air bags 3 is prevented, the body of the patient is ensured to be effectively turned over by the supporting air bags 3, and meanwhile, the body of the patient is prevented from sliding out of the supporting air bags 3, and the safety of the patient is ensured; in addition, when the inflatable mattress is in a flat state, the patient is found to be not at the optimal position close to the middle of the inflatable mattress, the turn-over of the patient by the subsequent inflatable mattress is not facilitated, at the moment, the driving device 6 can be started to drive the limit sliding block 5 to move, and the limit sliding block 5 pushes the body of the patient to move transversely until the body of the patient reaches the optimal position close to the middle, so that a good precondition is created for the subsequent turn-over. When the limiting slide block 5 plays a common limiting role, the driving device 6 is used in advance to push the limiting slide block 5 to a preset position before a patient lies down, then the patient lies down, and finally the position of the limiting slide block 5 can be finely adjusted by using the driving device 6, so that the patient is closer to the body of the patient.

In this embodiment, the limit slider 5 moves along the transverse channel 4, and the front and rear sides of the limit slider are provided with the support air bags 3, so that reliable sliding connection is difficult to realize between the two, and therefore, the limit slider 5 mainly slides by depending on the bottom surface of the limit slider; however, the turning-over air bag 2 is arranged below the supporting air bag 3, if the limiting slide block 5 slides on the turning-over air bag 2, the friction force between the two is larger, the limiting slide block 5 is required to be added with the driving device 6 to provide larger force when pushing the patient body, the load of the driving device 6 can be increased due to larger friction force, and the driving device 6 is required to ensure enough output force when being provided, so that the hardware cost is increased. Therefore, in this embodiment, preferably, the portion of the turning-over air bag 2 corresponding to the transverse channel 4 is hollowed out, the upper side surface of the cushion plate 1 is taken as the bottom surface of the transverse channel 4, that is, the transverse channel 4 always penetrates through the turning-over air bag 2 down to the upper surface of the cushion plate 1, the cushion plate 1 is made of plastic plates, steel plates or the like, the surface is smooth and has a certain hardness, the friction force between the two limiting sliding blocks 5 is small when the limiting sliding blocks slide on the upper side surface of the cushion plate 1, the requirement of the limiting sliding blocks 5 on the thrust of the driving device 6 is reduced when the limiting sliding blocks act, and the cost of the driving device 6 is reduced; and the smoothness of the limit sliding block 5 during movement is improved, the efficiency is improved, and the abrasion of the limit sliding block 5 is reduced.

When the patient turns over, the supporting air bags 3 are pushed to rise through the inflation of different parts of the turning over air bags 2, the supporting air bags 3 are fixed on the turning over air bags 2, the air chambers between the supporting air bags 3 are not communicated, all the supporting air bags 3 are mutually independent after being arranged, the uniform air pressure is not easily maintained, the inflating and deflating of each supporting air bag 3 are inconvenient, the integrity of the arranged supporting air bags 3 is poor, the supporting air bags are not pulled during the fluctuation, and each supporting air bag 3 is directly supported by the turning over air bags 2 completely. The inflatable mattress of this embodiment further includes side airbags 7 that are arranged on both sides of the support airbag 3 in the axial direction, the extending direction of the side airbags 7 is identical to the arrangement direction of the support airbags 3, both ends of the support airbags 3 are respectively connected to the side airbags 7 on both sides, and the side airbags 7 block the transverse channel 4 from both sides; all support air bags 3 are connected with the side air bags 7, the air chambers are also communicated, the side air bags 7 are inflated and deflated, the inflation and deflation of all support air bags 3 can be realized, the convenience of inflating and deflating all support air bags 3 is improved, the air pressure of all support air bags 3 can be maintained to be consistent, a patient can be supported in good balance, the side air bags 7 and all support air bags 3 form a complete whole, when the turning-over air bags 2 push a certain support air bags 3 to be lifted, the support air bags 3 are mutually pulled through the side air bags 7, the linkage effect is improved, the whole area is lifted jointly, and the turning-over effect is improved. And, the side gasbag 7 has plugged up transverse channel 4, with spacing slider 5 restriction in transverse channel 4 completely, on the one hand avoids spacing slider 5 to roll out transverse channel 4, on the other hand, when spacing slider 5 is in the limit state that one side supported patient's health and the opposite side supported on one of them side gasbag 7, side gasbag 7 can provide extra holding power for spacing slider 5, maintains spacing slider 5 to patient's supporting role under the limit state.

In this embodiment, the driving device 6 includes a push rod 61 connected to the limit slider 5, a portion of the side airbag 7 corresponding to the transverse channel 4 has a hole, the push rod 61 passes through the hole, and the driving motor 62 can drive the push rod 61 to transversely stretch out and draw back.
