Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and specifically relates to a pressure ulcer prevention and warming blanket. Background Technology
[0002] Pressure ulcers, also known as bedsores or pressure sores, are skin and / or tissue injuries localized to a specific body position. They occur due to prolonged pressure on local tissues, leading to insufficient blood supply, persistent ischemia, hypoxia, malnutrition, and ultimately, skin damage, ulceration, and even necrosis. They commonly occur in people who are bedridden or sitting for extended periods, especially those with limited mobility and restricted local nerve and blood supply.
[0003] Air mattresses are commonly used to prevent and alleviate pressure sores. However, air mattresses are monolithic and cannot be adjusted to individual needs, making them inconvenient to use. Furthermore, in cold weather, the air inside the mattress can be at the same temperature as the room temperature, which can easily cause people to catch a cold. Utility Model Content
[0004] The purpose of this utility model is to provide a pressure ulcer prevention and warming blanket to solve the technical problem of existing air mattresses that cannot be adjusted according to people's specific conditions and are prone to causing people to catch a cold in cold weather.

[0037] Reference Figure 1 and Figure 2 The following are several embodiments of the pressure ulcer prevention and warming blanket of this utility model.
[0038] like Figure 1 and Figure 2 As shown, the pressure ulcer prevention and heating blanket 100 of this utility model embodiment includes an inflatable cushion 200 and a heating pad 300.
[0039] It is understandable that the inflatable cushion 200 includes multiple air cushion units 210, such as Figure 1 As shown, multiple air cushion units 210 are arranged along the first direction, and two adjacent air cushion units 210 are connected in pairs, so that multiple air cushion units 210 are connected to form a square inflatable mat 200, on which people can lie down.
[0040] It is understandable that each air cushion unit 210 is connected to an inflation port 220, and each inflation port 220 is equipped with a switch 221, such as... Figure 1 As shown. Users can inflate the air cushion unit 210 through the inflation port 220 and control the connection of the inflation port 220 to an inflation device or the deflation of the air cushion unit 210 via the switch 221. Since each air cushion unit 210 is independently configured, users can individually control the inflation port 220 corresponding to each air cushion unit 210 to control the inflation status of each air cushion unit 210. This allows the inflatable cushion 200 to be adjusted according to each person's specific needs, meeting the requirements of different people and improving the applicability of the pressure ulcer prevention and warming blanket 100.
[0041] For example, for bedridden patients, the pressure can be distributed and pressure sores can be prevented by regularly inflating and deflating multiple air cushion units 210, changing the contact points between the patient's body and the air cushion 200.
[0042] For patients who already have pressure ulcers, a small amount of air can be inflated into the air cushion unit 210 corresponding to the pressure ulcer site, allowing the person to obtain support from other areas of the air cushion 200 and avoid further pressure on the pressure ulcer site.
[0043] Additionally, when a person lies supine on the inflatable mattress 200, the air cushion unit 210 corresponding to the head can be inflated with more air to form a pillow supporting the head and neck; the air cushion unit 210 corresponding to the waist can be inflated with more air to provide support for the waist, reduce pressure on the spine and lower back, and prevent pressure sores on the skin corresponding to the hips and ribs. When a person is in a side-lying position, the air cushion unit 210 corresponding to the waist can be inflated with more air to be used as a side-lying lumbar bridge.
[0044] Understandably, the heating pad 300 is used to raise the temperature, allowing people to use the pressure ulcer-preventing warm blanket 100 in cold weather, while preventing the inflatable pad 200, filled with cold air, from directly contacting the body and causing people to catch a cold. Specifically, the heating pad 300 and the inflatable pad 200 are positioned opposite each other vertically, such as... Figure 1 As shown, this ensures that the heating pad 300 can provide a stable temperature for the entire body. The heating pad 300 and the inflatable pad 200 are connected to each other to prevent misalignment of the heating pad 300 and the inflatable pad 200 due to activities such as turning over during use, which would prevent the heating pad 300 from failing to provide stable heating.
[0045] In this embodiment, the first direction is the left-right direction, that is, multiple air cushion units 210 are arranged and connected along the left-right direction, and each air cushion unit 210 extends along the front-back direction. When a person is lying down, their head rests on the left or right end of the pressure ulcer prevention and warming blanket 100.
[0046] In some embodiments, when the temperature is low, the heating pad 300 is positioned above the inflatable pad 200, and people lie on top of the heating pad 300, so that the heating pad 300 can directly provide heat to people and avoid the inflatable pad 200 affecting the heating effect of the heating pad 300.
[0047] In other embodiments, when the temperature is high, the inflatable pad 200 is positioned above the heating pad 300, such as... Figure 1 As shown. When the temperature is relatively hot, the heating pad 300 is in a non-working state. When the temperature is slightly cooler, the heating pad 300 located below is activated, and the air temperature inside the air pad 200 located above is raised through heat exchange. At this time, the heated air pad 200 can meet people's temperature needs, and there is no need to flip the heating pad 300 to the top of the air pad 200.
[0048] In some embodiments, the inflatable pad 200 and the heating pad 300 are fixedly connected, and their vertical positions can be adjusted by flipping them.
[0049] In this embodiment, the air cushion 200 and the heating pad 300 are detachably connected. Because the heating pad 300 can promote local blood circulation in the skin, improve skin ischemia, and prevent pressure sores, people can use the air cushion 200, the heating pad 300, or the integrated pressure sore-prevention heating blanket 100 alone.
[0050] Understandably, the inflatable pad 200 and the heating pad 300 can be detached by means of magnets, Velcro, or staples.
[0051] In this embodiment, the inflatable cushion 200 is connected with a plurality of first connecting buckles 230, which are arranged around the perimeter of the inflatable cushion 200, such as... Figure 1 As shown. Correspondingly, the heating pad 300 is connected to a plurality of second connecting buckles 310, which are arranged around the perimeter of the heating pad 300, as shown. Figure 2 As shown, multiple first connecting buckles 230 and multiple second connecting buckles 310 are arranged vertically in a one-to-one correspondence and are snapped together to fix them in place.
[0052] Understandably, the first connecting buckle 230 and the second connecting buckle 310 can be set on the fabric strip and sewn onto the air cushion 200 and the heating pad 300 respectively. The fabric strip material can be the same as the material of the air cushion 200 or the heating pad 300.
[0053] In some embodiments, the first connecting buckle 230 includes a first mounting buckle 231. Since the air cushion 200 is square, a plurality of first mounting buckles 231 are arranged along the four corners of the air cushion 200. Figure 1 As shown. Correspondingly, the second connecting buckle 310 includes a third mounting buckle 311, and multiple third mounting buckles 311 are arranged along the four corners of the heating pad 300, such as... Figure 2 As shown, multiple first mounting buckles 231 and multiple third mounting buckles 311 are positioned vertically opposite each other, and the air pad 200 and heating pad 300 are fixed by connecting and fixing them at the four corners.
[0054] In other embodiments, the first connecting buckle 230 includes second mounting buckles 232, and a plurality of second mounting buckles 232 are disposed along the four edges of the square inflatable pad 200, such as... Figure 1 As shown. Correspondingly, the second connecting buckle 310 includes a fourth mounting buckle 312, and multiple fourth mounting buckles 312 are arranged along the four edges of the square heating pad 300, such as... Figure 2As shown, multiple second mounting buckles 232 and multiple fourth mounting buckles 312 are positioned vertically opposite each other, and the inflatable pad 200 and the heating pad 300 can be fixed by connecting the four edges.
[0055] In this embodiment, the first connecting buckle 230 includes a first mounting buckle 231 and a second mounting buckle 232, and the second connecting buckle 310 includes a third mounting buckle 311 and a fourth mounting buckle 312. This allows the inflatable pad 200 and the heating pad 300 to be connected both at the four corners and along the four edges, ensuring a stable connection and preventing slippage or displacement of the inflatable pad 200 and heating pad 300 caused by movement on the pressure ulcer warming blanket 100. There are four first mounting buckles 231 and four third mounting buckles 311. Since the long end of the pressure ulcer warming blanket 100 extends in the left-right direction, there are six second mounting buckles 232 and six fourth mounting buckles 312. Taking the inflatable pad 200 as an example, there are two second mounting buckles 232 on each of the front and rear edges, and one second mounting buckle 232 on each of the left and right edges.
[0056] Understandably, heating pad 300 can be an electric heating wire blanket, a carbon fiber blanket, etc.
[0057] In this embodiment, the heating pad 300 is heated by water, which raises the temperature of the heating pad 300 by heating the liquid to meet people's heating needs. The water-heated heating pad 300 provides uniform heat transfer and high heat transfer efficiency, avoiding the uneven heating and overheating of some areas that can occur with electric heating wire blankets, which could lead to burns.
[0058] It is understood that the heating pad 300 includes a water bladder 320 and a heating element 330. The water bladder 320 has a heating chamber 321 for filling with liquid, such as... Figure 2 As shown. The water bladder 320 is connected to a water inlet, through which people can add water or other heatable liquids into the heating chamber 321. The electric heating element 330 is located inside the heating chamber 321 and heats the liquid inside the heating chamber 321 when connected to electricity.
[0059] Understandably, since the heating chamber 321 is filled with liquid, the liquid can protect and cushion the heating element 330, preventing people lying on the heating pad 300 from squeezing the heating element 330, and the liquid can prevent people from directly contacting the heating element 330.
[0060] It is understandable that the heating element 330 is connected to a power plug 331 via an external wire to the heating chamber 321, and the liquid is heated by electricity supplied through the power plug 331, such as... Figure 2 As shown.
[0061] It is understandable that the cross-section of the air cushion unit 210 in the working state is circular or elliptical, that is, the cross-section of the air cushion unit 210 in the front-to-back direction in the inflated state is circular or elliptical, and the arc surface of the air cushion unit 210 stably supports people's bodies.
[0062] It is understood that the air cushion unit 210 has an inflation port 220 connected to both ends along the second direction, which is a horizontal direction perpendicular to the first direction. Since the first direction is left and right, each air cushion unit 210 has an inflation port 220 at both its front and rear ends. When the bed with the pressure ulcer warming blanket 100 is placed against a wall, the air cushion unit 210 can be inflated and deflated through the inflation port 220 on the side not against the wall, ensuring that the pressure position of people when lying down is changed regularly to prevent pressure ulcers.
[0063] Understandably, the 220 inflation port comes with an 400 inflation balloon, such as... Figure 1 As shown. People can open the switch 221 at the inflation port 220, and the inflation port 220 can be connected through the inflation balloon 400. Pressing the inflation balloon 400 will inflate the air cushion unit 210.
[0064] Understandably, after the air cushion unit 210 and the inflatable balloon 400 are separated, the gas inside the air cushion unit 210 is directly output from the inflation port 220 due to its higher air pressure, resulting in a smaller actual inflation volume of the air cushion unit 210, which affects the support and pressure ulcer prevention function of the pressure ulcer prevention heating blanket 100.
[0065] To address this, the inflation port 220 is equipped with a one-way valve structure, which ensures that after the inflation balloon 400 and the inflation port 220 are disconnected, the inflated gas can be stably retained in the air cushion unit 210.
[0066] Furthermore, a three-way valve 410 is provided between the inflatable balloon 400 and the inflation port 220. The three-way valve 410 includes an air inlet, an air outlet, and a deflation port 411. The three-way valve 410 is connected to the inflatable balloon 400, that is, the air inlet and the inflatable balloon 400 are connected.
[0067] The three-way valve 410 is equipped with a valve 420, which controls the connection between the air inlet and the air outlet. When the air cushion unit 210 needs to be inflated, people can inflate it by pressing the inflatable balloon 400. The valve 420 can also control the connection between the air outlet and the deflation port 411. When the air cushion unit 210 needs to be deflated or is over-inflated, the air inside the air cushion unit 210 is output from the connected air outlet and deflation port 411, thereby regulating the amount of air inside the air cushion unit 210.
[0068] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
