[0048] Compared with the prior art, the utility model includes the following advantages:

[0049] In one aspect, the first back cavity and the second back cavity can be separated by the spacer, and the first back cavity and the second back cavity can be inflated separately by the first gas nozzle and the second gas nozzle. In this way, the first back cavity and the second back cavity can be controlled separately, and the height of the first back cavity and the height of the second back cavity can be adjusted separately, so that the height of the first back cavity and the height of the second back cavity can be different.

[0050] In this way, the human body can be tilted in the left-right direction without turning over the back air bag (so that the human body is automatically tilted to the side with a lower height, for example, the left side of the human body is higher than the right side, or the right side of the human body is higher than the left side), which is more convenient for assisting the human body to turn over. The medical staff can easily turn the human body to a prone position state by using the automatic tilt of the human body, reduce the difficulty of turning over, so that the turning over process can be completed in a short time, which is safe and effective, and requires fewer medical staff, reduces the labor intensity of medical staff, and improves the turning over efficiency.

[0051] On the other hand, the first back cavity and the second back cavity can be inflated and deflated separately by the first gas nozzle and the second gas nozzle, so that the difference between the height of the first back cavity and the height of the second back cavity can be quickly adjusted according to different needs during the turning over process, so as to improve the adjustment efficiency.

[0052] In another aspect, after the first back cavity is inflated, the bottom surface of the first back cavity is in an arc state or an inclined state, and the thickness of the first back cavity gradually increases in the direction from the left side of the first back cavity to the right side of the first back cavity. After the second back cavity is inflated, the bottom surface of the second back cavity is in an arc state or an inclined state, and the thickness of the second back cavity gradually decreases in the direction from the left side of the second back cavity to the right side of the second back cavity.

[0053] In this way, the height of the bottom surface from the position of the spacer in the back air bag to the left and right sides is increased, so that the human body can be turned over from left to right, or from right to left, and is not limited to one direction, which has higher freedom in the direction of turning over and is more suitable for various actual situations.

[0054] In another aspect, the height of the bottom surface from the position of the partition in the back air bag to the bottom surface of the left and right sides is respectively raised, the bottom surface is in an arc state or an inclined state, the whole back air bag is inclined to the left or to the right, the human body is inclined, the difficulty of turning over is reduced, the turning over process can be completed in a short time, the safety is high, the number of medical staff required is small, the labor intensity of medical staff is reduced, and the turning over efficiency is improved.

[0055] In still another aspect, the cavity of the back air bag and the cavity of the annular torso air bag are independent of each other, and are inflated and deflated separately, for example, before the human body is turned over from a supine position to a prone position, the back air bag is inflated, and the annular torso air bag is not inflated, so that in the process of turning over the human body from a supine position to a prone position, the annular torso air bag located in front of the chest of the human body does not affect the turning over, and after the human body is turned over from a supine position to a prone position, the annular torso air bag is inflated, so that the chest and abdomen of the human body are not in direct contact with the bed surface, but in contact with the annular torso air bag, thereby avoiding pressure sores on the chest and abdomen of the human body, for example, avoiding pressure sores on the shoulders (shoulder joints), clavicles, and hip bones (hip joints).

[0056] In still another aspect, the left outer edge of the annular torso air bag is detachably connected with the left outer edge of the first back cavity, and the right outer edge of the annular torso air bag is detachably connected with the right outer edge of the second back cavity, so that the annular torso air bag and the back air bag are separable.

[0057] In this way, after the human body is turned over from a supine position to a prone position, the medical staff can disconnect the left outer edge of the annular torso air bag from the left outer edge of the first back cavity, and disconnect the right outer edge of the annular torso air bag from the right outer edge of the second back cavity, so as to separate the annular torso air bag from the back air bag, and then the back air bag can be removed from the back of the human body, facilitating the medical staff to treat the lungs of the human body through the back of the human body.

[0058] The back air bag removed from the back of the human body can be worn on other human bodies that need to be turned over to assist them in turning over, improving the utilization rate of the back air bag, and reducing the cost of needing to prepare multiple back air bags in advance.

[0059] Secondly, after one of the annular torso air bag or the back air bag is damaged (for example, leaks, etc.), the damaged air bag can be replaced, and the undamaged air bag does not need to be replaced, avoiding unnecessary cost expenditure. BRIEF DESCRIPTION OF DRAWINGS

[0082] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0083] Generally, the patient lies on the bed in a supine position, if the patient needs to be prone position ventilation treatment, the patient needs to be turned over.

[0084] However, for critically ill patients, due to critical illness, consciousness disorder or sedation, they cannot exert themselves, making it very difficult to turn over independently, and it is also very difficult for medical staff to turn over the patient, usually requiring 3 to 6 medical staff to cooperate to complete the patient's turning over, requiring a large number of people, high labor cost, and difficult turning operation, wasting time and resulting in low turning efficiency.

[0085] Secondly, the patient maintains a prone position for a long time, which can cause pressure sores.

[0086] Pressure sores, also known as bedsores or pressure ulcers, are the most serious problems that can occur on the skin of long-term bedridden patients or patients with impaired mobility. Pressure sores have a high incidence, fast disease progression, are difficult to cure, and are prone to recurrence after healing, which has always been a problem in the medical and nursing fields.

[0087] Pressure sores are caused by long-term pressure on the skin of the body, affecting blood circulation, leading to skin and subcutaneous tissue damage, ulcers, and even necrosis, etc. They are commonly found in the protruding parts of the bones under pressure, such as shoulders (shoulder joints), hip bones (hip joints), ankles, and knees, etc.

[0088] Therefore, it is necessary to avoid pressure sores.

[0089] There is an urgent need for a device that can simultaneously meet multiple functions such as assisting the patient to turn over, reducing the number of people involved in turning over to reduce costs, reducing the difficulty of turning over, improving the efficiency of turning over, and preventing pressure sores.

[0090] However, there is currently no device that can simultaneously meet the above-mentioned multiple functions.

[0091] To this end, the utility model discloses a device for preventing pressure sores and assisting in turning over, which comprises

[0092] The back air bag 01 and the annular trunk air bag 02.

[0093] The back air bag 01 is used for being worn on the back of the human body 03, and the annular trunk air bag 02 is used for being worn on the chest and abdomen of the human body 03. For example, after the human body 03 wears the device for preventing pressure sores and assisting in turning over, the back air bag 01 is located on the back of the human body 03, and the annular trunk air bag 02 is located in front of the chest and abdomen of the human body 03.

[0094] The back air bag 01 is internally provided with a spacer 04, which divides the cavity in the back air bag 01 into a first back cavity 011 and a second back cavity 012 which are symmetrical and isolated from each other. The first back cavity 011 is located on the left side, and the second back cavity 012 is located on the right side. The material of the spacer 04 is the same as that of the shell of the back air bag 01.

[0095] The left outer edge of the annular trunk air bag 02 is detachably connected with the left outer edge of the first back cavity 011.

[0096] The right outer edge of the annular trunk air bag 02 is detachably connected with the right outer edge of the second back cavity 012.

[0097] The first back cavity 011 is provided with a first air nozzle, and the second back cavity 012 is provided with a second air nozzle.

[0098] The first air nozzle is used for inflating the first back cavity 011, and the second air nozzle is used for inflating the second back cavity 012.

[0099] In the scenario of using the inflator pump to connect the first air nozzle to inflate the first back cavity 011, the second back cavity 012 is not inflated. After inflating the first back cavity 011, the bottom surface of the first back cavity 011 is in an arc state or an inclined state, and the thickness of the first back cavity 011 gradually increases in the direction from the left side of the first back cavity 011 to the right side of the first back cavity 011.

[0100] Or, in the scenario of using the inflator pump to connect the second air nozzle to inflate the second back cavity 012, the first back cavity 011 is not inflated. After inflating the second back cavity 012, the bottom surface of the second back cavity 012 is in an arc state or an inclined state, and the thickness of the second back cavity 012 gradually decreases in the direction from the left side of the second back cavity 012 to the right side of the second back cavity 012.

[0101] The bottom surface 0111 of the first back cavity 011 is one of the opposite two end surfaces in the first back cavity 011 which is not used to contact the back of the human body 03.

[0102] The bottom surface 0121 of the second back cavity 012 is one of the opposite two end surfaces in the second back cavity 012 which is not used to contact the back of the human body 03.

[0103] The annular trunk air bag 02 has a third air nozzle for inflating the annular trunk air bag 02.

[0104] The function of the back air bag 01 is to facilitate the turning of the human body from the supine position to the prone position.

[0105] The annular trunk air bag 02 is to avoid pressure sores of the human body.

[0106] In the initial state, the human body lies on the bed, that is, the human body is in the supine position on the bed, at this time the human body does not wear the anti-pressure sore and auxiliary turning device.

[0107] If it is necessary to turn the human body, it is necessary to first dress the human body with the un-inflated anti-pressure sore and auxiliary turning device, if the human body is a patient, especially a critically ill patient, it is difficult to "lift the human body to a sitting position and then dress the human body with the anti-pressure sore and auxiliary turning device", therefore, the human body can be dressed with the anti-pressure sore and auxiliary turning device when the human body is in the supine position on the bed.

[0108] For example, the medical staff can first disassemble the back air bag 01 and the annular trunk air bag 02 in the anti-pressure sore and auxiliary turning device, then the medical staff can slightly lift the left shoulder 031, the left chest and the left abdomen of the human body 03, insert the second back cavity 012 in the back air bag 01 into the gap between the bed and "the left shoulder 031, the left chest and the left abdomen of the human body 03", and constantly slightly lift "the left shoulder 031, the left chest and the left abdomen of the human body 03" while inserting, until the first back cavity 011 in the back air bag 01 is flat on the left side of the trunk of the human body 03 and the second back cavity 012 in the back air bag 01 is rolled into a bundle at the position of the spine of the back of the human body 03, and then slightly put down the left shoulder 031, the left chest and the left abdomen of the human body 03.

[0109] Then, the medical staff can slightly lift the right shoulder 032, the right chest and the right abdomen of the human body 03, so that the position of the spine of the back of the human body 03 has a gap with "the right shoulder 032, the right chest and the right abdomen of the human body 03", the medical staff inserts his hand into the gap to pull out the second back cavity 02 in the back air bag 01 at the position of the spine of the back of the human body 03, so that the second back cavity 02 in the back air bag 01 is flat on the right side of the trunk of the human body 03, and then slightly put down the right shoulder 032, the right chest and the right abdomen of the human body 03.

[0110] At this time, the back air bag 01 is located between the back of the human body 03 and the bed surface, and the back of the human body 03 presses the back air bag 01. The back air bag 01 is not inflated. Then, the medical staff connects the left outer edge of the annular torso air bag 02 and the left outer edge of the first back cavity 011, and connects the right outer edge of the annular torso air bag 02 and the right outer edge of the second back cavity 012, and the left arm and the right arm of the human body 03 are wrapped inside the space surrounded by the back air bag 01 and the annular torso air bag 02, so as to facilitate turning over.

[0111] Figure 1 A schematic view of the back air bag before inflation is shown. Figure 1 A schematic view of the relationship between the device for preventing pressure sores and assisting in turning over and the front of the human body before turning over (when in a supine position) is shown.

[0112] Figure 2 A schematic view of the relationship between the annular torso air bag and the chest and abdomen of the human body is shown. Figure 2 The human body shown is the front of the human body.

[0113] Before turning over the human body, the back air bag 01 can be inflated first. Figure 3 A schematic view of the back air bag after inflation is shown. Figure 3 The bottom surface of the first back cavity 011 is shown in an arc state and the bottom surface of the second back cavity 012 is shown in an arc state.

[0114] The case where the bottom surface of the first back cavity 011 is in an inclined state and the bottom surface of the second back cavity 012 is in an inclined state is not shown in the figure.

[0115] Figure 3 The thickness of the first back cavity 011 and the thickness of the second back cavity 012 in the first back cavity 011 and the second back cavity 012 are both in the vertical direction.

[0116] Figure 3 The state shown is the state of the human body 03 before turning over (at this time, it is in a supine position, not turned over to a prone position), and at this time, the annular torso air bag 02 is in an uninflated state.

[0117] The bottom surface 0111 of the first back cavity 011 in the inflated back air bag 01 is in an arc state or an inclined state, and the bottom surface 0121 of the second back cavity 012 is in an arc state or an inclined state, which facilitates the medical staff to turn over the human body.

[0118] Figure 4 A schematic view of the relationship between the device for preventing pressure sores and assisting in turning over and the human body after turning over the human body (at this time, it is in a prone position) is shown.

[0119] After the human body 03 is turned over (at this time, it is in a prone position), the back air bag 01 can be deflated and the annular torso air bag 02 can be inflated to avoid the front pressure sores of the human body 03.

[0120] Figure 5 After the back air bag is deflated and the annular torso air bag is inflated, a schematic view of the relationship between the anti-pressure sore and auxiliary turning-over device and the human body.

[0121] It should be noted that the left side and the right side of the utility model are for the human body 03, for example, taking the front of the human body 03 as the reference, the left hand side of the human body 03 is the left side, and the right hand side of the human body 03 is the right side, and accordingly, in the back air bag 01, the first back cavity 011 is close to the left hand side of the human body 03, and the second back cavity 012 is close to the right hand side of the human body 03, so that the first back cavity 011 is located on the left side, and the second back cavity 012 is located on the right side.

[0122] Alternatively, the direction from the left hand side of the human body 03 to the right hand side of the human body 03 is the direction from the left side to the right side, or the direction from the right hand side of the human body 03 to the left hand side of the human body 03 is the direction from the right side to the left side.

[0123] Further, in another embodiment of the utility model, the anti-pressure sore and auxiliary turning-over device further comprises a front air bag 05.

[0124] The front air bag 05 is arranged on the side, away from the back air bag 01, of the opposite two end faces in the annular torso air bag 02.

[0125] The front air bag 05 has a spacer inside, and the spacer separates the cavity inside the front air bag 05 into the first front cavity 051 and the second front cavity 052 which are left-right symmetrical and isolated from each other. The first front cavity 051 is located on the left side, and the second front cavity 052 is located on the right side.

[0126] The material of the spacer inside the front air bag 05 is the same as that of the shell of the front air bag 05.

[0127] The left outer edge of the annular torso air bag 02 is detachably connected with the left outer edge of the first front cavity 051.

[0128] The right outer edge of the annular torso air bag 02 is detachably connected with the right outer edge of the second front cavity 052.

[0129] The first front cavity 051 has a fourth air nozzle, and the second front cavity 052 has a fifth air nozzle.

[0130] The fourth air nozzle is used for inflating the first front cavity 051, and the fifth air nozzle is used for inflating the second front cavity 052.

[0131] In the scenario where the fourth air nozzle is connected to the air pump to inflate the first front cavity 051, the second front cavity 052 is not inflated. After the first front cavity 051 is inflated, the bottom surface of the first front cavity 051 is in an arc shape or an inclined state, and the thickness of the first front cavity 051 gradually increases in the direction from the left side of the first front cavity 051 to the right side of the first front cavity 051.

[0132] Alternatively, in the scenario where the fifth air nozzle is connected to the air pump to inflate the second front cavity 052, the first front cavity 051 is not inflated. After the second front cavity 052 is inflated, the bottom surface of the second front cavity 052 is in an arc shape or an inclined state, and the thickness of the second front cavity 052 gradually decreases in the direction from the left side of the second front cavity 052 to the right side of the second front cavity 052.

[0133] The bottom surface of the first front cavity 051 is the surface of the opposite two end surfaces in the first front cavity 051 that is away from the annular torso air bag 02, that is, the surface of the opposite two end surfaces in the first front cavity 051 that does not contact the annular torso air bag 02.

[0137] Figure 6 The front air bag 05 is shown, Figure 6 a schematic view of the device for pressure sore prevention and turning assistance in the un-inflated state of the front air bag.

[0138] In the case where the duration of the human body 03 in a prone position reaches a certain requirement (for example, 8 hours, 12 hours, or 16 hours), the human body 03 needs to be turned from a prone position to a supine position.

[0139] In order to facilitate the human body 03 from the prone position to the supine position, the annular torso air bag 02 can be deflated first, and the front air bag 05 can be inflated.

[0144] Figure 7 The state shown is that the human body 03 has not been turned over (at this time, it is in a prone position and has not been turned over to a supine position), and at this time, the annular torso air bag 02 is in an un-inflated state.

[0145] The bottom surface of the first front cavity 051 in the inflated front air bag 05 is in an arc state or an inclined state, and the bottom surface of the second front cavity 052 is in an arc state or an inclined state, which facilitates the medical staff to turn over the human body.

[0167] The end of the annular leg air bag 07 can be understood as: after the human body wears the device for preventing pressure sores and assisting in turning over, the end farthest from the top of the head in the annular leg air bag 07.

[0168] The front end of the annular leg air bag 07 can be understood as: after the human body wears the device for preventing pressure sores and assisting in turning over, the end closest to the top of the head in the annular leg air bag 07.

[0169] In the utility model, under the condition that the human body 03 is in a prone position, the head 033 of the human body 03 presses the annular head air bag 06, the chest and abdomen of the human body 03 press the annular trunk air bag 02, and the leg of the human body presses the annular leg air bag 07.

[0171] The annular trunk air bag 02 has two opposite end faces, one of which is in contact with the chest and abdomen of the human body 03, and the other is in contact with the bed.

[0172] The annular leg air bag 07 has two opposite end faces, one of which is in contact with the leg of the human body 03 (and possibly also in contact with the foot of the human body 03), and the other is in contact with the bed.

[0178] wherein, Figure 14 A schematic diagram showing the thickness of the end of the annular head air bag is greater than or equal to the thickness of the front end of the annular leg air bag in a scenario where the human body is in a prone position. Figure 14 The back air bag and the front air bag are not shown in the illustrated schematic diagram.

[0179] In another embodiment of the present utility model, a pressure alarm is arranged at the position of the inner surface of the annular leg air bag 07 corresponding to the outer surface for fitting the knee of the human body 03.

[0181] A pressure alarm is arranged at the position of the inner surface of the annular leg air bag 07 corresponding to the outer surface for fitting the toe of the human body 03.

[0182] After the human body 03 wears the device for preventing pressure sores and assisting in turning over, the leg and foot of the human body 03 will press the annular leg air bag 07, for example, the outer surface of the annular leg air bag 07 for fitting the knee of the human body 03 is fitted with the knee of the human body 03, that is, the knee of the human body 03 will press the outer surface of the annular leg air bag 07 for fitting the knee of the human body 03.

[0183] The outer surface of the annular leg air bag 07 for fitting the ankle of the human body 03 is fitted with the ankle of the human body 03, that is, the ankle of the human body 03 will press the outer surface of the annular leg air bag 07 for fitting the ankle of the human body 03.

[0184] The outer surface of the annular leg air bag 07 for fitting the foot of the human body 03 is fitted with the foot of the human body 03, that is, the foot of the human body 03 will press the outer surface of the annular leg air bag 07 for fitting the foot of the human body 03.

[0185] In another embodiment of the present utility model, a pressure alarm is arranged at the position of the inner surface of the annular torso air bag 02 corresponding to the outer surface for fitting the shoulder of the human body 03.

[0186] The pressure alarm is arranged at the position of the inner surface of the outer surface of the annular trunk air bag 02 corresponding to the clavicle of the human body 03.

[0187] The pressure alarm is arranged at the position of the inner surface of the outer surface of the annular trunk air bag 02 corresponding to the iliac bone of the human body 03.

[0191] The pressure alarm is arranged at the position of the inner surface of the outer surface of the annular trunk air bag 02 corresponding to the iliac bone of the human body 03.

[0192] The preset threshold value can be set in the pressure alarm according to actual conditions, and the specific value can be determined according to actual conditions, which will not be described in detail in the utility model, and is not limited.

[0193] The pressure alarm is arranged at the position of the inner surface of the outer surface of the annular trunk air bag 02 corresponding to the iliac bone of the human body 03.

[0194] The pressure sensor is used to convert the pressure signal into an electrical signal. When the measured pressure changes, the sensitive element inside the sensor will deform or change in electrical properties, thereby outputting an electrical signal corresponding to the pressure.

[0195] The signal processing circuit is used to receive the electrical signal from the pressure sensor and perform amplification, filtering, linearization, etc. to obtain an accurate and stable pressure value. At the same time, the signal processing circuit will also compare the processed pressure value with the preset alarm threshold. If the pressure value exceeds the preset threshold, the circuit will trigger the alarm.

[0196] The alarm: when the pressure is greater than or equal to the preset threshold, the alarm will issue an audible and visual alarm signal to remind the operator to pay attention. The alarm can include a buzzer, an indicator light, a relay, etc.

[0197] In an embodiment of the present application, the left outer edge of the annular torso airbag 02 and the left outer edge of the first back cavity 011 are connected through a plurality of inserts.

[0198] The plurality of inserts can be spaced side by side, for example, 2 inserts spaced side by side or 3 inserts spaced side by side, etc.

[0199] The insert includes a plug and a lock. The plug can be inserted into the lock to achieve connection, and the plug can be pulled out of the lock to achieve disconnection.

[0200] In an embodiment, for any one of the plurality of inserts, the plug in the insert is fixedly connected between the first end of the first rope, for example, the plug in the insert is fixedly connected between the first end of the first rope through sewing, the second end of the first rope is fixedly connected with the left outer edge of the annular torso airbag 02, for example, the second end of the first rope is fixedly connected with the left outer edge of the annular torso airbag 02 through pasting. The lock in the insert is fixedly connected with the first end of the second rope, for example, the lock in the insert is fixedly connected with the first end of the second rope through sewing, the second end of the second rope is fixedly connected with the left outer edge of the first back cavity 011, for example, the second end of the second rope is fixedly connected with the left outer edge of the first back cavity 011 through pasting. The same is true for each of the other inserts in the plurality of inserts.

[0201] The plug can be inserted into the lock to connect the left outer edge of the annular torso airbag 02 and the left outer edge of the first back cavity 011, and in addition, the plug can be pulled out of the lock to disconnect the left outer edge of the annular torso airbag 02 and the left outer edge of the first back cavity 011.

[0202] The right outer edge of the annular torso airbag 02 and the right outer edge of the second back cavity 012 are detachably connected through a plurality of snap fasteners. The specific detachable connection manner can refer to the detachable connection manner between the left outer edge of the annular torso airbag 02 and the left outer edge of the first back cavity 011.

[0203] The left outer edge of the annular torso airbag 02 and the left outer edge of the first front cavity 051 are detachably connected through a plurality of snap fasteners. The specific detachable connection manner can refer to the detachable connection manner between the left outer edge of the annular torso airbag 02 and the left outer edge of the first back cavity 011.

[0204] The right outer edge of the annular torso airbag 02 and the right outer edge of the second front cavity 052 are detachably connected through a plurality of snap fasteners. The specific detachable connection manner can refer to the detachable connection manner between the left outer edge of the annular torso airbag 02 and the left outer edge of the first back cavity 011.

[0205] On the one hand, the cavities inside the back airbag can be divided into a first back cavity and a second back cavity which are left-right symmetrical and spaced apart by a spacer. The first back cavity and the second back cavity can be inflated separately by the first air nozzle and the second air nozzle. In this way, the control of the inflation amount in the first back cavity and the control of the inflation amount in the second back cavity can be realized respectively, so that the height of the first back cavity and the height of the second back cavity can be adjusted respectively, and the difference between the height of the first back cavity and the height of the second back cavity can be realized.

[0206] In this way, the human body can be tilted in the left-right direction without the medical staff turning over the back airbag (so that the human body automatically tilts to the side with lower height, for example, the left side of the human body's torso is higher than the right side, or the right side of the human body's torso is higher than the left side), which is more convenient for assisting the human body to turn over. The medical staff can easily turn the human body to a prone position state by using the automatic tilt of the human body, reduce the difficulty of turning over, so that the turning over process can be completed in a short time, which is safe and effective, and requires fewer medical staff, can reduce the labor intensity of medical staff, and improve the turning over efficiency.

[0207] On the other hand, the first back cavity and the second back cavity can be inflated and deflated separately by the first air nozzle and the second air nozzle, so that during the turning over process, the difference between the height of the first back cavity and the height of the second back cavity can be quickly adjusted according to different needs, so as to improve the adjustment efficiency.

[0208] In another aspect, after the first back cavity is inflated, the bottom surface of the first back cavity is in an arc shape or an inclined state, and the thickness of the first back cavity gradually increases in a direction from the left side of the first back cavity to the right side of the first back cavity, and after the second back cavity is inflated, the bottom surface of the second back cavity is in an arc shape or an inclined state, and the thickness of the second back cavity gradually decreases in a direction from the left side of the second back cavity to the right side of the second back cavity.

[0209] In this way, the height of the bottom surface from the position of the partition in the back air bag to the bottom surfaces on the left and right sides is respectively increased, so that the human body can be turned over from left to right or from right to left, and is not limited to turning over in one direction, and the degree of freedom of the turning over direction is higher, and is more suitable for various actual situations.

[0210] In another aspect, the height of the bottom surface from the position of the partition in the back air bag to the bottom surfaces on the left and right sides is respectively increased, and the bottom surface is in an arc shape or an inclined state, so as to facilitate tilting the back air bag as a whole to the left or to the right, thereby facilitating tilting the human body, more facilitating assisting the human body to turn over, reducing the difficulty of turning over, so that the turning over process can be completed in a short time, is safe and effective, and requires fewer medical personnel, can reduce the labor intensity of medical personnel, and improve the turning over efficiency.

[0211] In another aspect, the cavities of the back air bag and the annular torso air bag are independent of each other and are inflated and deflated separately, for example, before the human body is turned over from a supine position to a prone position, the back air bag is inflated, and the annular torso air bag is not inflated, so that during the process of turning over the human body from a supine position to a prone position, the annular torso air bag located in front of the chest of the human body does not affect the turning over, and after the human body is turned over from a supine position to a prone position, the annular torso air bag is inflated, so that the chest and abdomen of the human body are not in direct contact with the bed surface, but are in contact with the annular torso air bag, thereby avoiding pressure sores on the chest, shoulders (shoulder joints), clavicles, and hip bones (hip joints) of the human body.

[0212] In another aspect, the left outer edge of the annular torso air bag is detachably connected to the left outer edge of the first back cavity, and the right outer edge of the annular torso air bag is detachably connected to the right outer edge of the second back cavity, so that the annular torso air bag and the back air bag are separable.

[0213] Thus, after turning the body from a supine to a prone position, medical personnel can disconnect the left outer edge of the annular trunk airbag from the left outer edge of the first back cavity, and disconnect the right outer edge of the annular trunk airbag from the right outer edge of the second back cavity. This separates the annular trunk airbag from the back airbag, allowing the back airbag to be removed from the body's back, facilitating treatment of the lungs through the body's back.

[0214] Back airbags removed from the back of a human body can be worn on other people who need to turn over to assist them in doing so, which improves the utilization rate of back airbags and eliminates the need to pre-select multiple back airbags, thus reducing costs.

[0215] Secondly, if one of the ring-shaped torso airbags or back airbags is damaged (e.g., leaking air), only the damaged airbag needs to be replaced; there is no need to replace the undamaged airbag, thus avoiding unnecessary costs.

[0216] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
