Description
Technical Field
[0001] This utility model relates to the field of medical and nursing device technology, specifically to a three-fold turning mattress structure. Background Technology
[0002] Patients who are bedridden for a long time are prone to skin damage and even necrosis because the pressure of their body on the bed surface is concentrated in a fixed area. In addition, maintaining the same position for a long time can lead to the decline of bodily functions, and the lack of movement exercise for internal organs can affect overall health.
[0003] While existing two- or three-fold turning beds used in clinical practice can turn patients over by folding the bed, they generally have the following problems: during the turning process, the patient's position is changed by pushing force, which can easily cause compression or shearing force on the skin, increasing the risk of injury; and the turning angle of the bed is fixed and cannot be precisely adjusted according to the patient's physical condition, which may result in excessive or insufficient turning, which not only affects the nursing effect but also makes it difficult to meet the individual needs of different patients.
[0004] Therefore, there is an urgent need to propose a three-fold turning mattress structure to solve the above problems. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a three-fold turning mattress structure that can achieve precise control of the turning angle, reduce skin damage and promote reasonable changes in body position.
[0006] To achieve the above objectives, this utility model provides a three-fold flip-up mattress structure, wherein the mattress forms a left panel, a middle panel, and a right panel along its width direction; the left panel, the middle panel, and the right panel are hinged together by hinges for flipping the panels along the length direction of the mattress;
[0007] The hinge is equipped with an angle controller for adjusting the flip angle of the plate.

Detailed Implementation
[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0041] This utility model proposes a three-fold turning mattress structure, such as... Figure 1 and Figure 2 As shown, the mattress is divided into a left panel 1, a middle panel 2, and a right panel 3 along its width. The three parts are hinged together by a hinge 5 and can be flipped along the length of the mattress. An angle controller 6 is provided on the hinge 5 to adjust the flipping angle of each panel 4, avoiding skin compression or shearing force caused by excessive flipping.
[0042] like Figure 1 and Figure 2 As shown, the left panel 1 is composed of at least three panels 4 hinged together along the length of the mattress. The middle panel 2 and right panel 3 have the same structure, forming a multi-segment flip-up unit, allowing the mattress to also flip along its width. The hinges 5 are distributed correspondingly to each panel 4. An angle controller 6 is installed between the left panel 1 and the middle panel 2, and between the right panel 3 and the middle panel 2. The two controllers are located at the same end along the length of the mattress for easy centralized operation and maintenance.
[0043] like Figure 3 As shown, the hinge 5 includes a first hinge seat 51 and a second hinge seat 52. The former is fixed to the middle plate 2, and the latter is fixed to the left plate 1 or the right plate 3. The two are connected by a hinge shaft 53. The center distance between the hinge holes of the first hinge seat 51 is smaller than that of the second hinge seat 52. One end of the hinge shaft 53 is axially positioned with the second hinge seat 52 through a shoulder, and the other end is fixed with a bolt. A radial clearance is maintained between the hinge shaft 53 and the hinge hole of the first hinge seat 51 to allow relative rotation and provide a basis for angle adjustment.
[0044] like Figures 3 to 7As shown, a reduced-diameter journal is provided in the middle of the hinge shaft 53 to form a positioning ring 54, located between the two hinge holes of the first hinge seat 51. Its maximum radial dimension is smaller than the diameter of the hinge holes to avoid interference. The boss 55 on the positioning ring 54 cooperates with the angle controller 6: the angle controller 6 includes a split limiting ring 61 sleeved on the positioning ring 54 (fixed by bolts to the upper ring body 611 and the lower ring body 612). The first limiting groove 62 and the second limiting groove 63 on its inner wall can limit the rotation angle of the boss 55, and the rotation angle allowed by the second limiting groove 63 is greater than that of the first limiting groove 62, realizing the switching of different flipping amplitudes. The lower ring body 612 is connected to the drive rod 66 through the connecting rod 65. The drive rod 66 passes through the fixing seat 64 of the middle plate 2 and is threadedly connected to it. Rotating the drive rod 66 can switch the limiting grooves to precisely control the flipping angle.
[0045] Working principle:
[0046] Initial state: Left panel 1, middle panel 2, and right panel 3 are in a horizontally unfolded state, and each panel 4 is connected by hinges 5 to form a complete mattress.
[0047] Flip Trigger: When it is necessary to turn the patient to the left or right, the caregiver operates the corresponding side; taking the flip of the left panel 1 as an example, the second hinge seat 52 (fixed to the left panel 1) is connected to the first hinge seat 51 (fixed to the middle panel 2) through the hinge shaft 53. The hinge shaft 53 rotates relative to the hinge hole of the first hinge seat 51 (due to the retention of radial clearance), and the left panel 1 flips around the axis of the hinge shaft 53 along the length of the mattress, causing the left side of the patient's body to be lifted, thus achieving a side-lying posture.
[0048] The limiting ring 61 is a split structure, consisting of an upper ring body 611 and a lower ring body 612 fixed together by bolts. The connecting rod 65 below the lower ring body 612 is rotatably connected to the drive rod 66, which passes through and is fixed to the fixing seat 64 of the middle plate 2, and engages with the threaded hole on the inner wall of the fixing seat 64.
[0049] When the nursing staff rotates the drive rod 66 clockwise or counterclockwise, the threaded transmission causes the drive rod 66 to move axially, which in turn causes the limit ring 61 to slide axially along the hinge shaft 53.
[0050] When the boss 55 is in the first limiting groove 62, the rotation angle is limited to a small range (such as 0°~30°), which is suitable for mild decompression and turning over.
[0051] When the limiting boss 55 is in the second limiting groove 63, the allowable flipping angle can be increased significantly, and the rotatable angle can be expanded (such as 0°~60°) to meet the requirements of depth position change.
[0052] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
[0053] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
