[0035] Embodiment two, see Figure 3 The present embodiment is further improved,

[0036] A folding piece 6 is arranged between the upper body area 11 and the lower body area 12. The folding piece 6 is provided with a second air bag which can be independently inflated and deflated. The folding piece 6 is deflated when the upper body area 11 is lifted, and the volume of the folding piece 6 is reduced to form the gap 4. Further, the folding piece 6 is deflated by different amounts according to the angle of lifting of the upper body area 11, and the deflated folding piece 6 remains connected to the upper body area 11 and the lower body area 12.

[0037] A folding piece 6 is arranged between the upper body area 11 and the lower body area 12. The folding piece 6 is independently inflated and deflated, and is deflated when the hospital bed is lifted to form a gap 4 between the upper body area 11 and the lower body area 12, thereby reducing the pressure caused by the extrusion of the bending part. The folding piece 6 is inflated when the hospital bed is lowered to keep the air cushion body 1 flat. Further, the folding piece 6 is deflated by different amounts according to the angle of lifting of the hospital bed, so that the gas in the folding piece 6 is always in a saturated state, and the flatness of the air cushion body 1 in the lifted state is further maintained.

[0038] Further, the edges of the air cushion body 1 placed on both sides of the human body are provided with protrusions 7 which are higher than the plane of the air cushion body 1.

[0039] The protrusions 7 are higher than the plane of the air cushion body 1, and the patient's arms can be placed on the protrusions 7. More importantly, the protrusions 7 serve as boundary lines to remind the patient that he or she is located at the edge of the air cushion body 1 and needs to move to the middle to reduce the risk of falling out of bed.

[0040] Further, the air cushion body 1 is also provided with a plurality of tightening belts, which are used to bind the air cushion body 1 and the hospital bed, and the length of the tightening belts is adjustable. Further, the tightening belts include transverse tightening belts 81 and longitudinal tightening belts 82, one end of the longitudinal tightening belts 82 is connected with the head of the air cushion body 1, and the other end is connected with the tail of the air cushion body 1, and the two ends of the transverse tightening belts are respectively connected with the two sides of the air cushion body 1.

[0041] The air cushion body 1 is also provided with a plurality of tightening belts, which are used to bind the air cushion body 1 and the hospital bed, so that the connection between the air cushion body 1 and the hospital bed is more stable, and further, the tightening belts include transverse tightening belts 81 and longitudinal tightening belts 82, which are used to bind the air cushion body 1 and the hospital bed in the transverse and longitudinal directions, so that the air cushion body 1 cannot slide in any direction, and the air cushion body 1 is pulled by the tightening belts, so that the risk of wrinkles is smaller.

[0042] Further, the contact surface of the air cushion body 1 and the hospital bed is provided with antiskid glue or magic tape.

[0043] The contact surface of the air cushion body 1 and the hospital bed is provided with antiskid glue or magic tape, which increases the friction coefficient between the air cushion body 1 and the hospital bed, so that when the air cushion body 1 has elastic potential energy under pressure, the antiskid glue or magic tape, the tightening belts and the tightening device share the load, prevent the air cushion body 1 from sliding, and keep stable connection with the hospital bed.

[0044] In the third embodiment, the gap 44 reduces the stress caused by the extrusion of the bending part, and the upper body area 11 and the lower body area 12 also have compression ability, which can offset a part of the stress caused by the bending and the gravity of the upper body area 11 on the lower body area 12 when the upper body area 11 is raised. However, when the upper body area 11 is raised, a horizontal component of force is exerted on the patient, and when the upper body area 11 is inclined, a horizontal component of force is also exerted on the lower limbs by the patient's trunk, and considering the comfort of the patient, the friction coefficient of the surface of the air cushion body 1 is low, so that the patient is prone to slide to the tail of the bed. At the same time, due to the physiological curvature of the human spine, the waist and the surface of the air cushion body 1 are difficult to closely fit, and a cavity is easily formed, causing discomfort of the patient's waist. Therefore, referring to FIG. 6, the present embodiment is further improved based on the first embodiment, Figure 4

[0045] Further, one side of the upper body area 11 and the lower body area 12 close to the bed body is provided with a connecting piece 5; a third air bag is arranged in the gap 4, the third air bag includes a support surface 91 close to the trunk and an auxiliary surface 92 away from the trunk, and the elasticity of the support surface 91 is greater than that of the auxiliary surface 92; the third air bag is provided with a first air valve 3.

[0046] ​Preferably, the connecting part of the connecting member 5 and the upper body area 11 and the lower body area 12 is away from the gap 4, so that the third air bag can be inflated in a direction away from the gap 4, and the connecting member 5 can limit the third air bag.

[0047] Preferably, the volume of the third air bag and the cavity volume of the gap 4 match when the air cushion body 1 is in a horizontal state, so as to reduce the gap between the air cushion body 1 and the third air bag, reduce the probability of the patient's skin tissue and dirt falling into the gap 4, and improve the patient's comfort. The third air bag can be connected with the upper body area 11 and / or the lower body area 12, or can be independently arranged, which is not limited in the embodiment. When the patient uses the air cushion, the patient's torso part and the bed body limit the third air bag in the gap 4. The third air bag includes a supporting surface 91 and an auxiliary surface 92, the supporting surface 91 is close to the patient's torso part, and the auxiliary surface 92 is away from the torso part. Preferably, when the air cushion body 1 is placed horizontally on the bed body, the plane where the connecting line of the supporting surface 91 and the auxiliary surface 92 is located is horizontal, so that when the supporting surface 91 is inflated, the volume of the supporting surface 91 inflated towards the torso part is uniformly distributed.

[0048] Preferably, the supporting surface 91 and the auxiliary surface 92 are made of materials with different elasticities, so that the elasticity of the supporting surface 91 is greater than that of the auxiliary surface 92. When inflated, under the action of gas pressure, the supporting surface 91 is easy to expand towards the torso part, so that it is in contact with the torso part and plays a supporting role. At the same time, when the upper body area 11 is lifted, the supporting surface 91 is pressed down by the gravity of the torso part, and relatively, the inflated part of the supporting surface 91 has a counterforce to the torso part, so that the sliding of the torso part on the air cushion body 1 is reduced. The auxiliary surface 92 is difficult to expand, which reduces the cavity formed between the third air bag and the bed body, and reduces the situation that the supporting surface 91 and the auxiliary surface 92 are inflated at the same time and cause excessive support to the torso part. At the same time, the auxiliary surface 92 can be inflated, which forms a support to the air cushion body 1 on the premise that it does not cause excessive support to the patient, lifts part of the air cushion body 1 on both sides of the gap 4, so that the air cushion body 1 forms a slight arc, so as to cooperate with the third air bag and make it more fit the torso part and form a better supporting effect; at the same time, when the upper body area 11 is lifted, the third air bag is inflated, so that the supporting surface 91 and the auxiliary surface 92 are inflated, and under the pressing action of the gravity of the torso part, the supporting surface 91 and the auxiliary surface 92 are close to the part of the air cushion body 1 near the gap 4, so that the third air bag is not easy to fall off in the process of tilting the upper body area 11.

[0049] Further, the support surface 91 and the auxiliary surface 92 are provided with a separation surface, so that the support surface 91 and the separation surface are independent, forming a corresponding support air chamber 911 and an auxiliary air chamber 912. The support air chamber 911 and the auxiliary air chamber 912 are respectively provided with independent first air valves 3. The support air chamber 911 and the auxiliary air chamber 912 are respectively inflated, so that medical staff can better control the inflation of the third air bag, and more freely control the inflation amount under the premise of patient cooperation feedback, so that the third air bag achieves a better supporting effect on the patient driving part.

[0050] Further, the connection position of the support surface 91 and the auxiliary surface 92 is away from the support surface 91, and the height thereof is lower than a surface of the air cushion body 1 close to the torso. The connection position of the support surface 91 and the auxiliary surface 92 is higher than a surface of the air cushion body 1 close to the torso, and since the inflation speed of the auxiliary surface 92 is less than that of the support surface 91, when the patient's torso part forms pressure on the support surface 91, it will cause the support surface 91 close to the auxiliary surface 92 to fall, and a cavity is formed between the support surface 91 and the auxiliary surface 92, which is difficult to adhere to the air cushion body 1, thereby reducing the friction between the third air bag and the air cushion body 1, and causing the support surface 91 to be more prone to sliding. By setting the height of the connection position of the support surface 91 and the auxiliary surface 92 to be lower than a surface of the air cushion body 1 close to the torso, the inflation starting point of the support surface 91 is in the gap 4, so that the support surface 91 can be more closely adhered to the air cushion body 1, and it is difficult to form a cavity; at the same time, it can also avoid the shear effect of the auxiliary surface 92 on the support surface 91 due to different materials, which is beneficial to improve the safety of the air cushion body 1 during use and increase the service life of the air cushion body 1.

[0051] Further, the third air bag is provided with a balance air valve 31, and the upper body area 11 is provided with a first air valve 3; the balance air valve 31 and the first air valve 3 are connected through an air pipe. When the upper body area 11 is raised, the third air bag is inflated to adhere to the patient's waist and fill the cavity between the waist and the air cushion body 1. At the same time, the pressure of the torso part on the upper body area 11 decreases, and the pressure on the third air bag increases, which is easy to cause the pressure of the third air bag to increase, and the supporting effect on the patient is too large, causing discomfort. By connecting the third air bag and the upper body area 11, when the pressure of the third air bag exceeds a balance threshold, or when the patient feedbacks discomfort, the balance air valve 31 is opened, so that the third air bag inflates to the upper body area 11, reducing the pressure of the third air bag. At the same time, the pressure of the upper body area 11 is increased, so that it is inflated, and it plays a stronger supporting role on the inclined torso part.
