Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a novel positioning pad. Background Technology
[0002] Medical devices play a vital role in modern medicine. With the continuous advancement of medical technology, the performance and functional requirements for various medical devices are also increasing. In the operating room environment, patient positioning support is one of the key factors in ensuring the smooth progress of surgery. Different surgeries require different positioning, and appropriate positioning support not only ensures the precision of surgical procedures but also improves patient comfort during the procedure.
[0003] Currently, common methods for addressing patient positioning during surgery include gel surgical positioning pads, sponge surgical positioning pads, and conventional fluid pads. Gel surgical positioning pads utilize the properties of gel to provide a degree of support; sponge surgical positioning pads rely on the softness and elasticity of the sponge to fix the patient's position; and conventional fluid pads use the fluidity of their internal components to adjust their shape to fit the curves of the human body.
[0004] However, these conventional methods in existing technologies have significant drawbacks. Gel and sponge surgical positioning pads are both fixed in shape and cannot conform to the complex curves of different surgical positions, making it difficult to fully meet the diverse support needs of surgical positions. While conventional fluid pads can be shaped and conform to the curves of the human body, external moisture can easily enter the interior, causing internal swelling, which in turn prevents them from conforming to the body's curves and ultimately renders the product ineffective.
[0005] Among the aforementioned technologies, there is a drawback that the shaping effect of the positioning pad is not easily maintained. Utility Model Content
[0006] To address the issue of the difficulty in maintaining the shaping effect of a positioning pad, this application provides a novel positioning pad.
[0007] The novel positioning pad provided in this application adopts the following technical solution:
[0008] A novel positioning pad includes: an outer wrapping component comprising a first wrapping layer, a second wrapping layer, and a third wrapping layer, wherein the first wrapping layer is flexible, the second wrapping layer is sandwiched between the first wrapping layer and the third wrapping layer, the second wrapping layer supports the first wrapping layer and the third wrapping layer, both the first wrapping layer and the third wrapping layer are waterproof, and the first wrapping layer and the third wrapping layer are airtight, the outer wrapping component forming a receiving cavity; and an inner fluid layer filling the receiving cavity, the inner fluid layer being fluid.
[0009] By adopting the above technical solution, the first wrapping layer of the outer packaging is flexible, which improves comfort when in contact with the human body. The second wrapping layer is sandwiched between the first and third wrapping layers, serving to support both and ensure the overall structural stability of the positioning pad, while also providing a certain degree of support for the patient. Both the first and third wrapping layers are waterproof and airtight, preventing external moisture from entering the cavity and affecting the internal fluid layer, and preventing the evaporation of substances in the internal fluid layer, thus avoiding clumping of internal materials that could reduce shaping ability or product failure. The internal fluid layer fills the cavity and is fluid, allowing the positioning pad to be shaped according to different surgical positions, conforming to the curves of the human body. This not only fixes the surgical patient's position but also reduces the risk of pressure sores and postoperative sequelae, while also reducing the workload of medical staff.
[0010] Optionally, the first wrapping layer and the third wrapping layer have the same area, and both are larger than the area of the second wrapping layer. The first wrapping layer and the third wrapping layer extend beyond the edge of the second wrapping layer to form an edge seal.
[0011] By adopting the above technical solution, the first and third wrapping layers have the same area, both larger than the second wrapping layer. They extend beyond the edge of the second wrapping layer to form a sealing edge. This structural design better seals the cavity, preventing leakage of the internal fluid layer and ensuring the integrity and stability of the new positioning pad. Simultaneously, because the first and third wrapping layers are waterproof and airtight, the sealing operation further enhances the airtightness and waterproofing effect, preventing external moisture from entering and internal substances from evaporating or clumping. This ensures that the internal fluid layer maintains good fluidity and shaping ability, allowing the positioning pad to continuously and effectively conform to the body's curves, reducing the risk of pressure sores, alleviating postoperative sequelae, and also helping to reduce the workload of medical staff.
[0012] Optionally, the first wrapping layer is a flexible film.
[0013] By adopting the above technical solution, the first wrapping layer is soft in texture, which makes the surface of the positioning pad feel comfortable and meets the comfort needs of the human body when in contact.
[0014] Optionally, the third wrapping layer has the same structure as the first wrapping layer.
[0015] By adopting the above technical solution, the third wrapping layer uses a film with the same structure as the first wrapping layer, which makes the surface of the new positioning pad soft, conforms to the curve of the human body, and improves patient comfort.
[0016] Optionally, the density of the internal fluid layer is less than the density of water.
[0017] By adopting the above technical solution, the internal fluid layer has a low density, which can reduce the weight of the product, make it easier to shape it to fit the curves of the human body, reduce the risk of pressure sores caused by prolonged pressure during surgery, and at the same time, the lightweight positioning pad can reduce the workload of medical staff and make it easier to handle.
[0018] Optionally, the second coating layer is a polymeric gel.
[0019] By adopting the above technical solution, a second encapsulation layer made of polymer gel is sandwiched between a first and third encapsulation layer, which are flexible, waterproof, and airtight. This layer supports the first and third encapsulation layers and provides a certain degree of support to the patient using the properties of the gel. Simultaneously, the polymer gel's soft surface gives the positioning pad a pleasant tactile feel.
[0020] Optionally, the internal fluid layer comprises lightweight particles.
[0021] By adopting the above technical solution, the lightweight particles in the internal fluid layer have fluidity, which allows the positioning pad to be better shaped according to different surgical positions, conforming to the curves of the human body, fixing the position of the surgical patient while keeping the patient in a more comfortable state, and can also greatly reduce the risk of pressure sores, reduce postoperative sequelae, and reduce the workload of medical staff; moreover, the lightweight particles are relatively light in weight compared to other forms of materials, making the entire positioning pad lighter and easier for medical staff to operate.
[0022] Optionally, the lightweight particles in the internal fluid layer have viscous forces between them.
[0023] By employing the above-mentioned technical solution, the lightweight particles in the internal fluid layer of the new positioning pad possess viscous forces, allowing the internal fluid layer to better maintain its shape during use and avoiding uneven shaping caused by excessive flow. When the patient lies on the positioning pad, the viscous internal fluid layer can more closely conform to the body's curves, distributing pressure and further reducing the risk of pressure sores and postoperative complications. Simultaneously, its better conformation to the body also helps reduce patient movement during surgery, improving the stability of surgical procedures and thus reducing the workload of medical staff in maintaining patient positioning.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. The first wrapping layer is flexible and the inner fluid layer is fluid, so that the positioning pad can conform to the curve of different surgical positions and meet the support needs of different surgical positions.
[0026] 2. Both the first and third wrapping layers are waterproof and can isolate air, preventing external moisture from entering the interior and causing swelling, as well as the volatilization of internal substances leading to clumping, thus avoiding a decrease or failure in the product's shaping ability.
[0027] 3. Positioning pads conform to the curves of the human body, are made of soft material, reduce the risk of pressure sores, alleviate postoperative sequelae, and reduce the workload of medical staff. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation.

Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.
[0041] Example 1
[0042] like Figure 1 , Figure 2 and Figure 3 As shown in the illustration, this application discloses a novel positioning pad (hereinafter referred to as "positioning pad"). The positioning pad includes an outer wrapping component 1 and an inner fluid layer 2, and is used in the operating room to meet the support needs of different surgical positions and improve the problem of the positioning pad's shaping effect being difficult to maintain. When in use, the positioning pad is placed on the operating table and can be shaped according to different positions, conforming to the curves of the human body. The material is soft, and while fixing the surgical patient's position, it also puts the patient in a more comfortable state.
[0043] like Figure 1 , Figure 2 and Figure 4 As shown, the outer wrapping component 1 includes a first wrapping layer 11, a second wrapping layer 12, and a third wrapping layer 13. The first wrapping layer 11 is flexible, which can improve comfort when in contact with the human body. The second wrapping layer 12 is sandwiched between the first wrapping layer 11 and the third wrapping layer 13. The second wrapping layer 12 supports the first wrapping layer 11 and the third wrapping layer 13, ensuring the overall structural stability of the positioning pad; at the same time, it can also provide a certain degree of support for the patient.
[0044] An outer wrapping 1 forms a receiving cavity, which is filled with an inner fluid layer 2 made of a fluid material. The fluid layer 2 is fluid, allowing the positioning pad to mold to different surgical positions, conforming to the curves of the human body. This not only fixes the patient's position but also reduces the risk of pressure sores and postoperative complications, while also reducing the workload of medical staff. Specifically, the type of fluid material is not limited, as long as it meets the usage requirements.
[0045] like Figure 1 , Figure 2 and Figure 4As shown, both the first encapsulation layer 11 and the third encapsulation layer 13 are waterproof, and they also isolate the air. The first encapsulation layer 11 and the third encapsulation layer 13 can prevent external moisture from entering the cavity and affecting the internal fluid layer 2, and can also prevent the substances in the internal fluid layer 2 from evaporating, thus avoiding the clumping of internal materials that could lead to a decrease in shaping ability or product failure.
[0046] Optionally, the internal fluid layer 2 includes lightweight particles. The relative movement of these particles gives the internal fluid layer 2 fluidity, allowing the positioning pad to better conform to different surgical positions, adhering to the curves of the human body and securing the patient's position while ensuring their comfort. Compared to other materials, the lightweight particles are relatively lightweight, making the entire positioning pad lighter and easier for medical staff to handle. In this embodiment, the lightweight particles can be microspheres or other shapes; they can also be hollow. The lightweight particles in the internal fluid layer 2 have viscous forces, allowing the internal fluid layer 2 to better maintain its shape when the positioning pad is used, avoiding uneven shaping due to excessive flow. When the patient lies on the positioning pad, the viscous internal fluid layer 2 can more closely conform to the curves of the human body, distributing pressure and further reducing the risk of pressure sores and postoperative complications. Simultaneously, its better fit to the human body helps reduce patient movement during surgery, improving the stability of the surgical procedure and thus reducing the workload of medical staff in securing the patient's position. Specifically, the types of lightweight particles include, but are not limited to, spherical or hollow polyacrylonitrile; the internal fluid layer 2 may also include necessary fluids, including but not limited to lubricating oil; the viscous force between the particles of the internal fluid layer 2 may be provided by the fluids that make up it, and the type of fluid is not limited; the thickness of the internal fluid layer 2 and the overall thickness of the positioning pad can be determined as needed.
[0047] like Figure 1 , Figure 2 and Figure 4 As shown, the first wrapping layer 11 and the third wrapping layer 13 have the same area, and both are larger than the area of the second wrapping layer 12. The first wrapping layer 11 and the third wrapping layer 13 extend beyond the edge of the second wrapping layer 12 to form the sealing edge 4. This structural design can better seal the receiving cavity, prevent leakage of the internal fluid layer 2, and ensure the integrity and stability of the new positioning pad. The method of forming the receiving cavity of this positioning pad is not limited. It can be formed by two outer wrapping pieces 1 being stacked and fastened together, and the four sides of the two outer wrapping pieces 1 being sealed (not shown in the figure); or it can be formed by folding one outer wrapping piece 1 first, and then sealing the three folded sides, such as... Figures 1-3 As shown.
[0048] like Figure 1 , Figure 2 and Figure 4 As shown, when filling the internal fluid layer 2, a sealing edge can be reserved as a filling port. Since lightweight particles have adhesive force, in order to reduce the problem of reduced sealing quality caused by adhesion at the filling port, the filling port can be turned outward first to keep the inside of the filling port clean and improve the sealing quality.
[0049] Meanwhile, since the first wrapping layer 11 and the third wrapping layer 13 are waterproof and can isolate air, the sealing operation further enhances the effect of isolating air and waterproofing, preventing external moisture from entering and internal substances from evaporating or clumping, thereby ensuring that the internal fluid layer 2 maintains good fluidity and shaping ability, so that the positioning pad can continuously and effectively conform to the curve of the human body, reduce the risk of pressure sores, alleviate postoperative sequelae, and also help reduce the workload of medical staff.
[0050] like Figure 1 , Figure 2 and Figure 4 As shown, the third wrapping layer 13 has the same structure as the first wrapping layer 11, and the second wrapping layer 12 is a polymer gel. The first wrapping layer 11 and the third wrapping layer 13 can be any one or more of the following films: polyurethane film, polyethylene film, polyvinyl chloride film, polystyrene film, polyester film, nylon film, and polypropylene film. The flexible film is soft in texture, which makes the surface of the positioning pad comfortable to the touch and meets the comfort requirements of human contact. Furthermore, taking the first wrapping layer 11 and the second wrapping layer 13 as TPU film as an example, it is waterproof and can prevent external moisture from entering the internal fluid layer 2, avoiding internal swelling that affects the performance of conforming to the curve of the human body. The TPU film can also isolate air, prevent external gas from penetrating and prevent the evaporation of oil or water in the internal fluid layer 2, prevent internal materials from clumping and swelling, ensure the good shaping ability and performance of the positioning pad, reduce the risk of pressure sores caused by positioning pad problems, reduce postoperative sequelae, and also reduce the workload of medical staff. A second encapsulating layer 12, made of polymer gel, is sandwiched between a first encapsulating layer 11 and a third encapsulating layer 13, which are flexible, waterproof, and airtight. This layer supports the first and third encapsulating layers 11 and also provides a degree of support to the patient using the properties of the gel. Simultaneously, the polymer gel's soft surface gives the positioning pad a pleasant tactile feel.
[0051] Optionally, the hardness range of the first wrapping layer 11 and the third wrapping layer 13 is 80A to 90A. This hardness range allows the wrapping layers to combine softness with a certain degree of support. The softness can conform to the curves of the human body, allowing the patient to be in a more comfortable position when fixing the surgical patient's body position, reducing the risk of pressure sores and alleviating postoperative sequelae; the certain degree of support ensures that the wrapping layers can better cooperate with the internal fluid layer 2 to realize the shaping function of the positioning pad, and can also reduce the workload of medical staff in placing and adjusting the positioning pad.
[0052] like Figure 1 , Figure 2 and Figure 4 As shown, the density of the internal fluid layer 2 is less than that of water, which makes it easier for medical staff to operate and handle the positioning pad under special circumstances.
[0053] like Figure 1 , Figure 2 and Figure 4 As shown, an outer wrapping element 1 is made using a first wrapping layer 11, a second wrapping layer 12, and a third wrapping layer 13. An outer bladder is formed using this outer wrapping element 1. Fluidized material is then filled into the bladder, air is expelled, and the bladder is sealed to form the positioning pad. Air can be expelled by inserting a suction nozzle into the filling port. This positioning pad combines the soft surface properties of a gel pad with the flow and shaping properties of a fluid pad, significantly reducing the risk of pressure sores and alleviating postoperative complications. It also reduces the workload of medical staff. In relevant tests, this positioning pad showed lower hardness compared to existing positioning pads, resulting in a softer surface in contact with the body and improved comfort. Simultaneously, the average pressure value on this positioning pad is higher, providing better support and ensuring optimal performance. Understandably, the positioning pad also includes necessary structures for connection, support, positioning, limiting and sealing functions to enable the positioning pad to function properly; the shape, size, material and number of each part of the positioning pad can be determined as needed to achieve the corresponding functions.
[0054] The implementation principle of a novel positioning pad according to an embodiment of this application is as follows: the first wrapping layer 11 of the outer wrapping component 1 is flexible and can conform to the human body, making it more comfortable for the patient to use; the second wrapping layer 12 is sandwiched between the first wrapping layer 11 and the third wrapping layer 13, playing a supporting role, ensuring the overall structural stability of the positioning pad and providing support for the patient; the internal fluid layer 2 fills the cavity and has fluidity, allowing the positioning pad to be shaped according to different surgical positions, conforming to the curves of the human body, effectively dispersing pressure on the body, greatly reducing the risk of pressure sores, and alleviating postoperative pressure sores. This plasticity also facilitates operation by medical staff, reducing their workload. Both the first wrapping layer 11 and the third wrapping layer 13 are waterproof and can isolate air. On the one hand, they can prevent external moisture from entering the cavity and causing the internal fluid layer 2 to become damp and clump, ensuring that the internal fluid layer 2 always has good fluidity to achieve a better shaping effect to fit the curves of the human body in different surgical positions. On the other hand, they can prevent oil or water in the internal fluid layer 2 from evaporating and causing the material to clump, avoiding a serious decrease in shaping ability or even product failure.
[0055] Example 2
[0056] like Figure 5 and Figure 6 As shown, this embodiment provides a novel positioning pad, which is basically the same as the first embodiment, except that: one side of the outer wrapping 1 is provided with a filling port 3 for filling the internal fluid layer into the receiving cavity, and the inner wall of the filling port 3 is provided with a detachable anti-stick layer 31.
[0057] The anti-adhesion layer 31 effectively prevents the internal fluid layer from adhering to the inner wall of the filling port 3 during the filling process, ensuring a smooth filling process. It also facilitates subsequent sealing of the filling port 3 by removing the anti-adhesion layer 31, reducing the risk of the sealing effect being affected by internal fluid layer material adhering to the filling port 3. Specifically, the anti-adhesion layer 31 is annular after installation, allowing it to be circumferentially installed on the inner wall of the filling port 3, optimizing the anti-adhesion effect. The anti-adhesion layer 31 has protrusions 32 located at its ends, facilitating disassembly. When it is necessary to remove the anti-adhesion layer 31, medical personnel can use the protrusions 32 to more easily remove it from the inner wall of the filling port 3, improving the convenience and efficiency of the operation, which is beneficial for the filling of the internal fluid layer 2 and the normal use of the subsequent positioning pad. After the internal fluid layer is filled and the anti-adhesive layer 31 is removed, the filling port 3 is sealed to form a sealing edge 4, thus ensuring that all three sides of the positioning pad are sealed with sealing edges 4. The protrusion 32 can be the end of the anti-adhesive layer 31 or a protruding structure located at the end of the anti-adhesive layer 31, whichever is required.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
