Description

Technical Field

[0001] This utility model relates to the field of prone positioning pad technology, specifically to a prone positioning pad with adjustable support pressure. Background Technology

[0002] A prone positioning pad is used to elevate a patient's abdomen, placing them in a prone position. It is commonly used to assist in procedures such as prone peritoneal lavage and abdominal surgery, ensuring the patient maintains the required position.

[0003] Prone positioning mats are typically made of soft, absorbent, and moisture-proof materials to ensure patient comfort. The mats have multiple grooves to accommodate different body shapes and proportions, thus ensuring accurate positioning and patient comfort.

[0004] However, while existing prone positioning pads can be adjusted to support different patient body shapes, they are often used for extended periods, especially in intensive care units. This requires regular and timely adjustments to the patient's position and the pad's position to prevent damage from prolonged pressure on a particular area. However, it is difficult to adjust different parts of the positioning pad during patient use, and it is also difficult to adjust the contact surface between the pad and the patient's skin. Furthermore, the pad is not breathable and can easily increase skin pressure. Utility Model Content

[0005] The purpose of this invention is to provide a prone positioning pad with adjustable support pressure to solve the technical problem that prolonged pressure from the prone positioning pad in the prior art can easily increase skin pressure.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] An adjustable support pressure prone positioning pad includes a pad plate, a pad block is provided on the pad plate, at least two sets of movable module groups are provided on the pad block, and a drive component for controlling its lifting and lowering is provided under the movable module groups. The two sets of movable module groups alternately lift and lower to form a pressure adjustment structure.

[0008] A displacement component is provided under the pad, and the pad moves along the length direction of the pad plate to form a distance adjustment structure.

[0009] As a preferred embodiment of this utility model, the cross-sections of the two sets of active modules are in the form of a grid structure, and the two sets of active modules are arranged in an alternating manner.

[0010] As a preferred embodiment of the present invention, the movable module group includes a module, a support frame and a positioning column, wherein the positioning column is composed of a positioning sleeve and a positioning rod.

[0011] The positioning sleeve is fixedly installed on the inner bottom wall of the pad, and the support frame is slidably installed on the top of the positioning sleeve via the positioning rod. Multiple modules are equally spaced on the support frame.

[0012] As a preferred embodiment of this utility model, the drive assembly includes a double-headed rotary motor, a bevel gear, a driven gear, and a screw. The output end of the double-headed rotary motor is connected to the bevel gear via a coupling. The bevel gear meshes with the driven gear. The inner wall of the driven gear is provided with a thread that matches the screw.

[0013] The driven gear is sleeved on the outer wall of the screw, and a support sleeve is movably mounted on the bottom end of the driven gear via a rotating shaft. The bottom end of the support sleeve is fixed to the inner bottom wall of the pad, and the top end of the support sleeve is sleeved on the outer wall of the screw.

[0014] As a preferred embodiment of the present invention, the displacement component includes a slide rail fixed in the pad, a slider slidably connected to the slide rail on the lower surface of the pad, a limiting block slidably connected to the outside of the pad by an elastic rod on the outer wall of the slider, and a magnetic strip provided at the connection position between one side of the limiting block and one side of the pad.

[0015] The elastic rod includes a fixed sleeve fixedly disposed on the outer wall of the slider, and a movable rod connected to the limiting block is installed on the inner wall of the fixed sleeve by a spring.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention employs a grid-distributed support structure that can be alternately raised and lowered.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a prone position pad with adjustable support pressure, including a pad plate 10, a pad block 20 on the pad plate 10, at least two sets of movable module groups 21 on the pad block 20, and a drive component 22 for controlling its lifting and lowering under the movable module group 21. The two sets of movable module groups 21 alternately lift and lower to form a pressure adjustment structure.

[0030] A displacement component 11 is provided under the pad 20, and the pad 20 moves along the length direction of the pad plate 10 to form a distance adjustment structure.

[0031] This invention employs a grid-distributed support structure that can be alternately raised and lowered. Two sets of modules on the pad are raised and lowered in an alternating manner, which helps to form a breathable channel, reduce the skin contact area and lower pressure. At the same time, when lying prone, the support of a certain part of the pad can be adjusted according to the patient's body position, thereby avoiding discomfort or even damage caused by prolonged pressure on a certain part. In addition, the adjustable distance of the pad can better adapt to different patient body shapes, thereby reducing patient discomfort.

[0032] The shifting component 11 facilitates the adjustment of the combination distance between different pads 20 and the adjustment of the support position of the pads 20, thereby facilitating adjustment according to the patient's body shape. Furthermore, when the patient is prone, the alternating adjustment of the two sets of movable modules 21 helps to relieve the pressure on the patient while prone and enhances the breathability, thereby improving the patient's comfort.

[0033] like Figure 2 and Figure 3 As shown, the cross-sections of the two sets of active module groups 21 are in the form of a grid structure, and the two sets of active module groups 21 are arranged in an alternating manner.

[0034] The alternating grid-like support ensures support while evenly distributing pressure, and also allows for ventilation through the gaps in the lowered set of movable modules 21.

[0035] like Figure 2 and Figure 4 As shown, the active module group 21 includes module 211, support frame 212 and positioning column 213. The positioning column 213 is composed of positioning sleeve 213a and positioning rod 213b.

[0036] The positioning sleeve 213a is fixedly installed on the inner bottom wall of the pad block 20, and the support frame 212 is slidably installed on the top of the positioning sleeve 213a through the positioning rod 213b. Multiple modules 211 are evenly spaced on the support frame 212.

[0037] The bottom of the pad 20 is made of rigid material, while the top is made of flexible material, so that the bottom can support the movable module group 21 while the top provides flexible support in contact with the patient.

[0038] The positioning rod 213b moves up and down within the positioning sleeve 213a, which helps to control the position of the module 211 and enhances the support effect on the module 211 and the support frame 212, thereby enhancing the stability of the moving module group 21 in raising and lowering.

[0039] Multiple modules 211 are supported and fixed by the support frame 212, and the cross-section of the support frame 212 is also grid-shaped, which helps to reserve lifting space for the drive components 22 of the two sets of support frames 212.

[0040] like Figure 4 As shown, the drive assembly 22 includes a double-headed rotary motor 221, a bevel gear 222, a driven gear 223, and a screw 224. The output end of the double-headed rotary motor 221 is connected to the bevel gear 222 via a coupling. The bevel gear 222 meshes with the driven gear 223. The inner wall of the driven gear 223 is provided with a thread that matches the screw 224.

[0041] The driven gear 223 is sleeved on the outer wall of the screw 224, and the bottom end of the driven gear 223 is movably mounted with a support sleeve 225 through a rotating shaft. The bottom end of the support sleeve 225 is fixed to the inner bottom wall of the pad 20, and the top end of the support sleeve 225 is sleeved on the outer wall of the screw 224.

[0042] The bevel gear 222 is rotated by the double-headed rotating motor 221. The bevel gear 222 meshes with the driven gear 223, driving the driven gear 223 to rotate. The driven gear 223 is threadedly connected to the screw 224 through the internal thread. This threaded connection between the driven gear 223 and the screw 224 converts the rotation into the lifting and lowering of the screw 224, which in turn drives the support frame 212 and the module 211 to lift and lower.

[0043] At the same time, the driven gear 223 is supported by the support sleeve 225, and the screw 224 is supported, so that the screw 224 can move up and down in the height direction of the support sleeve 225.

[0044] The dual-head rotating motor 221, in conjunction with a relay and a circuit switch, can be configured to rotate alternately on both shafts, so that one end of the dual-head rotating motor 221 rotates while the other end stops rotating, thereby achieving the purpose of alternating lifting and lowering of the two sets of movable module groups 21.

[0045] like Figure 2 and Figure 5 As shown, the displacement assembly 11 includes a slide rail 111 fixed inside the pad 10, a slider 112 slidably connected to the slide rail 111 on the lower surface of the pad 20, and a limiting block 114 slidably connected to the outside of the pad 10 via an elastic rod 113 on the outer wall of the slider 112, and a magnetic strip is provided at the connection position between one side of the limiting block 114 and one side of the pad 10.

[0046] The elastic rod 113 includes a fixed sleeve 113a fixedly disposed on the outer wall of the slider 112, and a movable rod 113b connected to the limiting block 114 is installed on the inner wall of the fixed sleeve 113a by a spring.

[0047] The pad 20 moves horizontally on the slide rail 111 via the slider 112, and the slider 112 is connected to the outer limit block 114 via the elastic rod 113, which allows the operator to pull the limit block 114 to separate it from the pad 10 and drag the pad 20 for sliding adjustment. When the pad 20 is adjusted to the appropriate position, the limit block 114 is released, and the elastic rod 113 is reset by the spring. The limit block 114 is magnetically connected and fixed to the pad 10 via a magnetic strip.

[0048] The support position of the pads 20 can be easily adjusted to suit different patient body shapes, thereby achieving better support, reducing patient discomfort, and facilitating better treatment.

[0049] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
