Description

Technical Field

[0001] This invention relates to the field of pressure ulcer prevention air cushions, and more specifically, to multifunctional pressure ulcer prevention air cushions. Background Technology

[0002] Existing multi-functional pressure ulcer prevention air mattresses primarily reduce pressure between the skin and the mattress by using air exchange technology, thereby reducing the incidence of pressure ulcers. These air mattresses consist of multiple air bladders connected by air channels, allowing for even air flow and distribution within the mattress. When a patient lies on it, the air mattress adjusts the inflation level of the air bladders according to the body's shape and position to achieve optimal pressure distribution. However, for patients with certain conditions, existing multi-functional pressure ulcer prevention air mattresses cannot be adjusted to suit different patient conditions. This can lead to increased burden on the patient's body instead of providing relief. For example, patients with lumbar disc herniation may experience worsened symptoms, such as severe lower back pain and numbness in the lower limbs, because the relatively soft nature of the air mattress may exacerbate the burden on the lumbar spine.

[0003] For example, the Chinese invention patent (application number: CN202210639447.8) discloses a "multifunctional anti-pressure ulcer air cushion," whose specification states that pressure ulcers are one of the most serious complications for long-term bedridden patients, with a high mortality rate, causing immense suffering to patients and their families. Currently available anti-pressure ulcer air cushions and air mattresses have many drawbacks, such as their overall inflation failing to meet the needs of patients turning over. Furthermore, the immobility of the legs of bedridden patients hinders blood circulation, increasing the risk of thrombosis. This is detrimental to improving the quality of life for bedridden patients and reducing the risk of pressure ulcers; the aforementioned patent demonstrates the deficiencies of existing technologies.

[0004] Therefore, we made improvements and proposed a multifunctional pressure ulcer prevention air cushion. Summary of the Invention

[0020] In the scheme of this application:

[0021] 1. In order to solve the problem that the existing multifunctional anti-pressure ulcer air cushions cannot be adjusted according to different patients with different diseases, this application, through the setting of a support plate and the support air bladder set on its top, realizes the ability to select to fill the support air bladder with gas, liquid or not fill it at all according to different situations, and thus adjust it according to different patients' conditions;

[0022] 2.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0041] As described in the background section, existing multifunctional pressure ulcer prevention air cushions cannot be adjusted to suit different patients with different diseases, which results in patients not only not getting better when using them, but also increasing the burden on their bodies.

[0042] To address this technical problem, the present invention provides a multifunctional pressure ulcer prevention air cushion, which is applied to a multifunctional adaptive pressure ulcer prevention air cushion.

[0043] For details, please refer to Figures 1-10 The multifunctional pressure ulcer prevention air cushion specifically includes:

[0044] It includes an installation component 1, a support component 2 evenly arrayed on the top of the installation component 1, a drive component 3 connected to the bottom of the support component 2 by a pipe, and a knee pad component 4 provided on the top of the support component 2.

[0045] The support assembly 2 includes two sets of staggered support plates 201. The top surface of the support plate 201 is triangular and its two ends are radial. The top surface of the support plate 201 is horizontal. An electric heating wire is embedded in the top of the support plate 201. A support airbag 202 is fixedly installed on the top of the support plate 201. A mounting bracket 203 is fixedly installed on one side of the bottom of the support plate 201. A water bag 204 is fixedly wrapped on the outside of the mounting bracket 203. The mounting bracket 203 is located at the smaller end of the support plate 201.

[0046] The multifunctional pressure ulcer prevention air cushion provided by this invention, through the array of drive components and support components, facilitates local adjustment, thereby allowing for corresponding adjustments based on different patient conditions.

[0047] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0048] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0050] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 The multifunctional anti-pressure sore air cushion's support component 2 also includes a fixing rod 206 sleeved on the bottom of the support plate 201. The side wall of the fixing rod 206 is arrayed with exhaust pipes 207, and the interior of the fixing rod 206 is hollow. The hollow fixing rod 206, together with the exhaust pipes 207, is used to release pressure during resetting. The top of the fixing rod 206 is spherical, and the bottom of the fixing rod 206 is fixedly connected to the mounting component 1. The bottom pipe of the mounting frame 203 is connected to a transport pipe 205, and the outside of the transport pipe 205 has a built-in valve body. The transport pipe 205 is a rubber hose, and the bottom of the transport pipe 205 is connected to the drive component 3.

[0051] The exhaust pipes 207 arranged in an array facilitate depressurization of the device's interior. At the same time, the exhaust pipes facilitate air blowing to the bottom of the support plate 201 while depressurizing, thereby enabling ventilation of the patient's back.

[0052] Please refer to Figure 3 , Figure 6 , Figure 7 and Figure 8The multifunctional pressure ulcer prevention air cushion has a driving component 3 including a storage tube 301 disposed between two sets of fixing rods 206. A partition 302 is fixedly installed in the middle of the inner cavity of the storage tube 301. Main tubes 304 are provided on both sides of the storage tube 301 at intervals. The outer side of the main tube 304 is connected to the transport tube 205, and the outer side of the main tube 304 is connected to a drain tube 306. The drain tube 306 and the transport tube 205 are distributed at intervals.

[0053] By setting up a storage tube 301 to store the transport solution, the circulation of the solution can be facilitated.

[0054] Furthermore, such as Figure 6 and Figure 7 As shown, the inner pipe of the main pipe 304 is connected to the third delivery pipe 311. The outer side of the third delivery pipe 311 has a built-in valve body. The other end of the third delivery pipe 311 is connected to the mounting sleeve 307. The connection between the third delivery pipe 311 and the mounting sleeve 307 is a flexible hose connection. The other end of the mounting sleeve 307 is connected to the transport hose 310. The other end of the transport hose 310 is provided with a second delivery pipe 309. The outer side of the second delivery pipe 309 has a built-in valve body. The other end of the second delivery pipe 309 is connected to the side wall pipe of the fixing rod 206.

[0055] The connection is made via a flexible hose to avoid resistance when the mounting bracket 203 is tilted.

[0056] Example 2 further optimizes the multifunctional pressure ulcer prevention air cushion provided in Example 1, specifically, as follows: Figure 7 and Figure 8 As shown, the bottom of the mounting sleeve 307 is rotatably connected to the mounting assembly 1, and the mounting sleeve 307 is inclined. A transmission extension rod 308 extending to the outside is sleeved inside the mounting sleeve 307. The top of the transmission extension rod 308 is concave, and the bottom of the transmission extension rod 308 contacts the inner wall of the mounting sleeve 307 through a sealing ring. When solution continuously flows into the mounting sleeve 307, it pushes the transmission extension rod 308 outward. A support sleeve 313 is provided above the mounting sleeve 307, and the support sleeve 313 is inclined. The bottom end of the support sleeve 313 is rotatably connected to the mounting assembly 1. The support sleeve 313 has an outwardly extending support rod 314 inside. One end of the support rod 314 is rotatably connected to the bottom of the mounting bracket 203, and the other end of the support rod 314 is fixedly installed with a compression spring 315. The other end of the compression spring 315 is fixedly connected to the inner wall of the support sleeve 313. A connecting ball rod 312 is fixedly installed on the side wall of the support sleeve 313, and the other end of the connecting ball rod 312 is spherically connected to the top of the transmission rod 308. When the transmission rod 308 extends outward, the support sleeve 313 and the support rod 314 are tilted by the connecting ball rod 312.

[0057] The installation sleeve 307 and the transmission extension rod 308 facilitate the support of the support sleeve 313 and also allow it to be moved. At the same time, they form a triangular shape with the support sleeve 313, which helps to increase the stability of the device and limit the position of the support sleeve 313.

[0058] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, vacuum pumps 303 are provided at both ends of the storage tube 301. The output ends of the vacuum pumps 303 are connected to the storage tube 301 pipeline, and each output end has a built-in valve body. The output ends of the vacuum pumps 303 are symmetrically distributed about the partition plate 302. First delivery pipes 305 are arranged in an array on both sides of the storage tube 301, and the other end of the first delivery pipe 305 is connected to the main pipe 304 pipeline. The outer side of the first delivery pipe 305 has a built-in valve body. The vacuum pumps 303 are used to pressurize the inside of the storage tube 301, thereby driving the internal solution to move.

[0059] The vacuum pump 303 creates high pressure inside the storage tube 301, which facilitates the movement of the solution.

[0060] Example 3 further optimizes the multifunctional pressure ulcer prevention air cushion provided in Example 1 or 2, specifically, as follows: Figure 1 As shown, the installation assembly 1 includes a bed 101 sleeved on the outside of the support plate 201. Drainage grooves 102 are provided at the bottom of both sides of the bed 101. The drainage grooves 102, together with the drainage pipes 306, are used to clean the inside of the bed 101. Knee pad assemblies 4 are symmetrically arranged on both sides of the bed 101. A controller assembly 103 is fixedly installed at one end of the bed 101, and a time relay is embedded inside the controller assembly 103.

[0061] Example 4 further optimizes the multifunctional pressure ulcer prevention air cushion provided in the above embodiments, such as... Figure 9 and Figure 10 As shown, the knee brace assembly 4 includes an array of arc-shaped sleeves 401 mounted on the side wall of the bed frame 101. A connecting pipe 402 is provided at the bottom of the arc-shaped sleeve 401, and the outer side of the connecting pipe 402 is equipped with a valve body. Both ends of the connecting pipe 402 are short rubber tubes. The other end of the connecting pipe 402 is connected to the pipe of the mounting bracket 203. The arc-shaped sleeve 401 is connected to the matching pipe of the mounting bracket 203, and the arc-shaped sleeve 401 is located in the lower middle part of the bed frame 101.

[0062] The connecting fitting 402 facilitates the connection between the water bladder 204 and the arc-shaped sleeve 401.

[0063] Furthermore, such as Figure 9 and Figure 10As shown, the inner cavity of the arc-shaped sleeve 401 is provided with movable blocks 403. The outer sides of adjacent movable blocks 403 are hinged to each other. There are cracks on the inner side of the movable blocks 403 to facilitate their bending and sliding. The top of the arc-shaped sleeve 401 is provided with a support crossbar 405. One end of the support crossbar 405 passes through the side wall of the arc-shaped sleeve 401 and is fixedly connected to the movable block 403. The other end of the support crossbar 405 is fixedly installed with a knee pad 406.

[0064] Furthermore, such as Figure 9 and Figure 10 As shown, the inner pipe of the arc-shaped sleeve 401 is connected to a vent pipe 404, and the outer side of the vent pipe 404 has a valve body. The vent pipe 404 is located between the connecting pipe 402 and the movable block 403.

[0065] The connectable fitting 402 can be opened to connect the water bladder 204 with the arc-shaped sleeve 401. At this time, the movable block 403 and the support plate 201 move synchronously. At the same time, the connection can be disconnected and the vent pipe 404 can be opened. Then, the support crossbar 405 can be pulled directly and moved to the appropriate position.

[0066] The multifunctional pressure ulcer prevention air cushion provided by this invention is used as follows:

[0067] First, remove the device and place it in the appropriate position. At the same time, fill the storage tube 301 with an appropriate amount of solution and fill the support balloon 202 with a certain amount of gas and liquid according to the patient's needs, or leave it unfilled.

[0068] In use, the patient lies flat on top of the support airbag 202 in the array. If it is necessary to turn the patient over, firstly, the vacuum pump 303 on one side is started to increase the pressure inside the storage tube 301, and only the valve body on the outer wall of the transport tube 205 and the first delivery tube 305 is opened. At this time, the solution inside the storage tube 301 is transported to the inside of the water bag 204 through the first delivery tube 305, the main tube 304 and the transport tube 205 under pressure. At this time, the weight inside the water bag 204 increases continuously, and the mounting bracket 203 drives the narrower end of the support plate 201 to rotate along the fixing rod 206. Then, the larger end of the support plate 201 and the support airbag 202 lift half of the patient's body.

[0069] As the water bladder 204 is filled with solution and descends, the arc-shaped sleeve 401 connected to the water bladder 204 is also filled with solution under pressure, which in turn pushes the internal support crossbar 405 and movable block 403 to move synchronously, thereby driving the knee pad 406 to move, so that it can be placed on the patient's knees when the patient is lying on their side. As the water bladder 204 descends, it will squeeze the support extension rod 314 under the limit of the installation sleeve 307 and move into the support sleeve 313. Since the installation sleeve 307 is sealed to the transmission extension rod 308, it will form a triangular shape with the support sleeve 313, thereby supporting and limiting it until the patient tilts to the appropriate position.

[0070] At this time, there will be gaps between the support plates 201 supporting the patient's back, which makes it easier to observe the patient's back and apply medicine, and also makes it easier for the patient's back to breathe.

[0071] When it is necessary to lay the patient flat, simply turn off the vacuum pump 303 and release the pressure through the pressure relief valve on the top of the storage tube 301, or open the exhaust pipe 207. The pressure relief operation can be achieved through the exhaust pipe 207 in conjunction with the second delivery pipe 309, the mounting sleeve 307, and the third delivery pipe 311. The released gas can also be sprayed to the bottom of the support plate 201 to achieve ventilation. After the pressure relief is completed, the pressure relief valve is closed. At this time, the solution inside the water bag 204 returns to the main pipe 304 and the storage tube 301 under the action of gravity. This process is repeated to achieve the patient's left and right turning operation. At this time, in conjunction with the time relay embedded in the controller group 103, the two sets of vacuum pumps 303 can be started at intervals to perform the patient's reciprocating turning at regular intervals.

[0072] When it is necessary to adjust the patient's lying angle, open the valve body on the outer wall of the first delivery pipe 305 and the third delivery pipe 311 corresponding to the angle to be adjusted, and start the two sets of vacuum pumps 303. At this time, the solution is continuously transported to the inside of the mounting sleeve 307 through the main pipe 304 and the third delivery pipe 311, which in turn continuously lifts the transmission extension rod 308, which pushes the support sleeve 313 and the support extension rod 314 to tilt along the bottom of the support sleeve 313. The mounting bracket 203 pushes the support plate 201 to tilt. The staggered and symmetrical support plate 201, together with the support airbag 202, pushes the patient's body to tilt. Repeat the above steps to tilt any part of the patient as needed.

[0073] If the patient needs to lie flat, repeat the above steps to depressurize the storage tube 301, thereby allowing the support plate 201 to reset.
