Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a high-strength support turning over air cushion. Background Art

[0002] At present, many patients are bedridden for a long time due to limb movement disorders and are unable to turn over by themselves. In this case, the patient's blood distribution will change, resulting in congestion of organs close to the bed and increased hydrostatic pressure, which will cause exudation. Especially in the lungs, this may lead to accumulation of secretions, causing lesions such as aspiration pneumonia. In addition, blood stasis will also affect venous return, leading to the formation of intravenous thrombosis, resulting in serious consequences; when the patient lies flat on the bed, due to long-term pressure on the back, blood circulation is not smooth, muscle tissue is damaged, and bedsores are very likely to occur.

[0003] The current solution to this problem is to ask caregivers or nurses to help patients turn over regularly to change their positions intermittently. This practice can promote the discharge of tracheal secretions, reduce the pressure of the heart on the sagging lung area, improve the ratio of ventilation and blood flow, increase ventilation, and improve the long-term pressure on local skin and muscle tissue, thereby reducing complications caused by long-term bed rest, such as aspiration pneumonia and bedsores.

[0004] However, this method of turning over mainly relies on manual operation, so there are problems such as insufficient manpower, forgetfulness or laziness caused by busyness. In addition, when turning over with manual assistance, the tubes of critically ill patients may slip off due to excessive force of the person turning over. When axis turning is required, it is often difficult to complete it by one person. Therefore, the existing turning method does need further improvement.

[0005] Although there are special turning beds on the market, they are expensive and difficult to disinfect, making them unsuitable for popularization in ordinary wards. Ordinary turning air cushions are relatively soft and lack support. Utility Model Content

[0006] Technical problems to be solved by utility models

[0007] Aiming at the existing technical problems of insufficient manpower, forgetfulness or laziness caused by busyness in manual turning, expensive price and difficulty in disinfection of special turning beds, softness and insufficient support of ordinary turning beds, the utility model provides a high-strength turning air cushion, which solves the problems of insufficient manpower, forgetfulness or laziness caused by busyness in manual turning, expensive price and difficulty in disinfection of special turning beds, softness and insufficient support of ordinary turning air cushions. The utility model has strong support, is easy to use and comfortable.

[0008] Technical Solution

[0009] In order to solve the above problems, the technical solution provided by the utility model is:

[0010] A high-strength support turning over air cushion comprises a flexible shell, which is in the shape of a triangular column, a top inflation area is provided at the top of the shell, a bottom inflation area is provided at the bottom of the shell, a plurality of support inflation columns are provided between the top inflation area and the bottom inflation area, an inflation cavity is provided between the support inflation columns, the support inflation columns and the inflation cavity are isolated from inflation, a traction inflation rod is connected in the middle of the support inflation column, an elastic element is provided inside the traction inflation rod, and the elastic element is fixed to the shell.

[0011] The supporting inflatable column and the inflatable cavity are inflated in isolation. The supporting inflatable column divides the space inside the whole air cushion, increases the air pressure of the supporting inflatable column or the inflatable cavity to improve the supporting force, and the whole air cushion will not become too hard and lack comfort due to excessive air pressure. After the space is divided, the high air pressure inside the supporting inflatable column or the inflatable cavity will not place too high requirements on the overall material strength of the air cushion. On the other hand, it reduces the risk of explosion and improves the safety factor. The traction inflatable rod can adjust the shape of the supporting inflatable column in both non-inflated and inflated conditions. When it is not inflated, the elastic element shortens and stretches the middle of the supporting inflatable column in one direction, so that the supporting inflatable column is regularly placed and will not be randomly stacked to cause local bulges to hurt the patient; when inflated, the elastic element stretches, so that the middle part of the supporting inflatable column returns to the state where the supporting inflatable column is upright.

[0012] The supporting inflatable column is provided with an intermediate node, and the intermediate node is fixedly connected to the traction inflatable rod and divides the supporting inflatable column into two upper and lower parts.

[0013] Furthermore, the inner space of the supporting inflatable column is further divided, and the column wall of the supporting inflatable column has great strength after being inflated, and the upper and lower parts can obtain greater supporting force after being inflated.

[0014] The traction inflatable rod is communicated with the support inflatable column.

[0015] Furthermore, one inflation port is reduced, making inflation more convenient.

[0016] A ventilation channel is provided in the middle node, and the ventilation channel connects the upper and lower parts of the supporting inflatable column.

[0017] Furthermore, the ventilation channel is used to connect the upper and lower parts of the supporting inflatable column.

[0018] The upper and lower parts of the supporting inflatable column are respectively symmetrical cones, and the large ends of the cones are connected to the bottom and the top of the shell.

[0019] Furthermore, the large end of the cone has a larger area, which can improve the uniformity of the air pressure support at the bottom and top of the shell, making the patient's contact with the support more comfortable.

[0020] The supporting inflation column and the inflation cavity are respectively connected with different inflation ports and inflation pipes.

[0021] Furthermore, the inflation port and the inflation pipe are used for inflation.

[0022] The inflation pressure of the supporting inflatable column is higher than the inflation pressure of the inflatable cavity.

[0023] Furthermore, the supporting air columns have a stronger supporting force, thereby improving the overall supporting force of the air cushion.

[0024] Included is a connecting strap that connects two mirror-image turning air cushions.

[0025] Furthermore, two mirror-image turning air cushions are connected, and the patient needs to overcome the bottom friction of the two air cushions when turning over, which improves the stability of the air cushions.

[0026] The bottom surface of the shell is provided with uniformly distributed friction points.

[0027] Furthermore, it is used to increase the friction of the air cushion and reduce slipping.

[0028] A direct contact surface is provided on the top surface of the shell, and random patterns are provided on the direct contact surface.

[0040] Example 1

[0041] Combined with Figure 1-4 A high-strength support turning over air cushion comprises a flexible shell 1, the shell 1 is in the shape of a triangular column, a top inflation area 2 is provided at the top of the shell 1, a bottom inflation area 9 is provided at the bottom of the shell 1, a plurality of support inflation columns 3 are provided between the top inflation area 2 and the bottom inflation area 9, an inflation cavity 8 is provided between the support inflation columns 3, the support inflation columns 3 and the inflation cavity 8 are isolated from inflation, a traction inflation rod 5 is connected in the middle of the support inflation column 3, an elastic element 6 is provided inside the traction inflation rod 5, and the elastic element 6 is fixed to the shell 1.

[0042] The supporting air-filled column 3 and the air-filled cavity 8 are isolated from inflation. The supporting air-filled column 3 divides the space inside the whole air cushion, and the air pressure of the supporting air-filled column 3 or the air-filled cavity 8 is increased to improve the supporting force. The air cushion as a whole will not become too hard and lack comfort due to excessive air pressure. After the space is divided, the high air pressure inside the supporting air-filled column 3 or the air-filled cavity 8 will not place too high requirements on the material strength of the whole air cushion. On the other hand, it reduces the risk of explosion and improves the safety factor.

[0043] The traction and inflatable rod 5 can adjust the shape of the supporting inflatable column 3 in both non-inflated and inflated conditions. When not inflated, the elastic element 6 shortens and stretches the middle of the supporting inflatable column 3 in one direction, so that the supporting inflatable column 3 is regularly placed and will not be randomly stacked to cause local protrusions that hurt the patient; when inflated, the elastic element 6 stretches to return the middle part of the supporting inflatable column 3 to the state where the supporting inflatable column 3 is upright. This high-strength support turning air cushion is unique, with a flexible shell 1 as the core, and presents a triangular column appearance. It can be used in Figure 1 As can be seen from left to right, the length of the supporting inflatable column 3 varies with the height of the triangular cross-section of the shell 1, and is stepped, fitting the top surface of the air cushion, making the patient feel more comfortable.

[0044] The top inflatable area 2 and the bottom inflatable area 9 are respectively arranged inside the shell 1 to construct a stable air cushion structure. Between the top and bottom inflatable areas 9, a plurality of supporting inflatable columns 3 stand therebetween to provide strong support for the air cushion. An inflatable cavity 8 is provided between these supporting inflatable columns 3 to ensure that the air cushion can maintain appropriate elasticity and comfort when inflated. It is worth mentioning that the supporting inflatable column 3 and the inflatable cavity 8 are independent of each other, avoiding the problem of the air cushion being too hard due to excessive air pressure. This design not only improves the support force, but also ensures the comfort of the user. At the same time, by reasonably dividing the internal space, the requirements for the strength of the air cushion material are effectively reduced, the safety performance is further enhanced, and the risk of explosion is reduced. In addition, the design of the traction inflatable rod 5 cleverly adjusts the shape of the supporting inflatable column 3. When not inflated, the elastic element 6 is shortened, the supporting inflatable column 3 is stretched in one direction, and the neat arrangement is maintained to avoid local protrusions causing discomfort to the user. When inflated, the elastic element 6 is stretched to restore the supporting inflatable column 3 to an upright state, providing a stronger support force. In short, this high-strength support turning air cushion achieves all-round support and protection for the user through careful design and humanized considerations. Whether from the perspective of material selection, structural design or ergonomics, it demonstrates a deep understanding and high attention to the needs of users.

[0045] The supporting air column 3 is provided with an intermediate node 4, which is fixedly connected to the traction air rod 5 and divides the supporting air column 3 into two parts, an upper part and an lower part. Further, the high-strength supporting turning air cushion is provided with an intermediate node 4 on the supporting air column 3. These intermediate nodes 4 not only enhance the structural stability of the air cushion, but also further optimize the inflation effect. The intermediate node 4 is firmly connected to the traction air rod 5, dividing the supporting air column 3 into two parts, an upper part and an lower part. This design not only effectively divides the internal space of the supporting air column 3, but also makes each part have a higher strength after inflation. Through the setting of the intermediate node 4, the supporting air column 3 of the upper and lower parts can provide greater support after inflation. This optimized design not only improves the supporting performance of the air cushion, but also ensures that the patient gets enough support when turning over or moving, thereby reducing the risk of skin damage caused by uneven pressure distribution. In addition, the presence of the intermediate node 4 also provides a more flexible adjustment method for the inflation and deflation process. By reasonably controlling the inflation amount of the upper and lower parts, the overall performance of the air cushion can be better balanced to meet the needs of different body shapes and usage scenarios. In summary, the addition of the intermediate node 4 further improves the performance and comfort of the high-strength support turning air cushion, making it a more complete and humanized medical auxiliary device. The shell 1 and the supporting inflatable column 3 are made of PU plastic, which is light and relatively strong, effectively extending the service life.

[0046] The traction inflation rod 5 is connected to the support inflation column 3. Furthermore, one inflation port is reduced, and inflation is more convenient.

[0047] A ventilation channel 11 is provided in the middle node 4, and the ventilation channel 11 connects the upper and lower parts of the supporting inflatable column 3. Furthermore, the ventilation channel 11 is used to connect the upper and lower parts of the supporting inflatable column 3. The upper and lower parts of the supporting inflatable column 3 are respectively symmetrical cones, and the large ends of the cones are connected to the bottom and top of the shell 1. Furthermore, the large end of the cone has a larger area, which can improve the uniformity of the air pressure support at the bottom and top of the shell 1, making the patient contact with the support more comfortable.

[0048] The supporting inflatable column 3 and the inflatable cavity 8 are respectively connected with different inflatable ports and inflatable pipes. Furthermore, the inflatable ports and inflatable pipes are used for inflating. The inflatable pipes are connected with an inflating device, and a controller is arranged in the inflating device.

[0049] The inflation pressure of the supporting inflatable column 3 is higher than the inflation pressure of the inflatable cavity 8. Furthermore, the supporting inflatable column 3 has a stronger supporting force, thereby improving the supporting force of the air cushion as a whole.

[0050] The bottom surface of the shell 1 is provided with uniformly distributed friction points 10, which are made of latex or rubber, greatly improving the friction. The top surface of the shell 1 is provided with a direct contact surface, and the direct contact surface is provided with random patterns. Furthermore, it is used to improve the friction of the air cushion and reduce slipping.

[0051] Example 2

[0052] Combined with Figure 1-4 Compared with the technical solution of Example 1, the high-strength support air cushion of this embodiment can be improved as follows:

[0053] It also includes a connecting belt 14, which connects the two mirror-image turning air cushions. Furthermore, the two mirror-image turning air cushions are connected, and the patient needs to overcome the bottom friction of the two air cushions when turning over, which improves the stability of the air cushions. The inflation pipeline is connected to an inflation device, and a controller is provided in the inflation device. The inflation device is respectively connected to the first inflation pipeline 13 and the second inflation pipeline 15. The controller controls the first inflation pipeline 13 and the second inflation pipeline 15 to be inflated and deflated alternately at regular intervals, so as to realize the regular alternating operation of the inflation cushions.

[0054] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
