Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a self-adjustable body position anti-bedsore massage air cushion. Background Technology
[0002] Postoperative bedridden patients or those confined to bed for extended periods due to illness are prone to pressure sores if they do not receive adequate care. Prolonged muscle relaxation can lead to muscle atrophy; lack of bone movement due to prolonged inactivity can cause bone loss; poor blood circulation from bed rest can increase the risk of blood clots and cardiovascular disease; bed rest can also lead to lung infections and respiratory failure, as well as constipation and gastrointestinal disorders. Doctors typically recommend that long-term bedridden patients receive prompt and regular repositioning to minimize the risk of complications.
[0003] Currently, existing air mattresses physically isolate the patient from the bed. However, in a supine position, the back remains in constant contact with the upper part of the air mattress, preventing the skin and muscles from fully releasing pressure and alleviating pressure sores by changing position. They also cannot provide continuous massage and acupressure stimulation to stimulate muscle contraction, prevent muscle atrophy, or increase blood circulation. Therefore, it usually requires assistance from caregivers and family members to change from a supine to a lateral position, increasing their workload.
[0004] Aside from patients with intracranial diseases or traumatic brain injury resulting in impaired consciousness, most long-term bedridden patients are generally conscious and have free upper limb movement, but are unable to turn over independently. If patients could turn over independently without external assistance and choose muscle massage and acupoint stimulation, the complications associated with long-term bedridden patients could be greatly alleviated, reducing the burden on their families. Based on this, this invention provides a self-turning adjustable body position anti-bedsore massage air cushion to assist bedridden patients in achieving self-turning. Utility Model Content
[0005] Based on the above analysis, the present invention aims to provide a self-turning adjustable body position anti-bedsore massage air cushion to solve the problem that existing air cushions have limited functions and are not suitable for use by long-term bedridden patients.
[0006] The objective of this utility model is mainly achieved through the following technical solutions:
[0007] A self-turning adjustable body position anti-bedsore massage air cushion includes: a gas distribution chamber, an air pump, a self-turning auxiliary air cushion layer, a massage cushion, an air cushion isolation layer, a horizontal air inflation line, a vertical air inflation line, and a vacuum pump.
[0008] The massage pad is laid in the middle of multiple self-turning assist air cushion layers; the self-turning assist air cushion layer is composed of multiple arrayed airbag modules; the airbag modules expand after inflation, which can assist the patient in adjusting their posture; the air cushion isolation layer is located below the self-turning assist air cushion layer, and the horizontal inflation pipes and vertical inflation pipes are nested inside the air cushion isolation layer; the horizontal inflation pipes are arranged in parallel and are connected to the gas diversion chamber; multiple vertical inflation pipes are arranged in parallel on the horizontal inflation pipes, and the vertical inflation pipes are connected to the airbag modules; the number of vertical inflation pipes is the same as the number of airbag modules, and they correspond one-to-one; the vacuum pump is simultaneously connected to multiple horizontal inflation pipes to achieve air extraction from multiple airbag modules.
[0009] Furthermore, a primary solenoid valve is provided at one end of the horizontal inflation pipe connected to the gas diversion chamber, and a secondary solenoid valve is provided on the vertical inflation pipe; the massage pad and the self-turning auxiliary air cushion layer are bonded and fixed together using Velcro.
[0010] Furthermore, the self-turning auxiliary air cushion layer includes: a central air cushion group, an isolation air cushion group, and a side-turning air cushion group; the isolation air cushion group is disposed on both sides of the central air cushion group, and at least one group is disposed on each side; the side-turning air cushion group is disposed on the outside of the isolation air cushion group.
[0011] Furthermore, the central air cushion assembly includes: a first airbag module, a second airbag module, a third airbag module, a massage airbag module, a fourth airbag module, and a fifth airbag module; the first airbag module, the second airbag module, and the third airbag module are located in the same column as the massage airbag module and are arranged vertically above the massage airbag module; the fourth airbag module and the fifth airbag module are located in the same column as the massage airbag module and are arranged vertically below the massage airbag module.
[0012] Furthermore, the isolation air cushion assembly includes: a sixth airbag module, a seventh airbag module, an eighth airbag module, a ninth airbag module, a tenth airbag module, and an eleventh airbag module arranged longitudinally.
[0013] Furthermore, the side-rollover air cushion assembly includes: a twelfth airbag module, a thirteenth airbag module, a fourteenth airbag module, a fifteenth airbag module, a sixteenth airbag module, and a seventeenth airbag module arranged longitudinally.
[0014] Furthermore, multiple horizontal inflation lines are arranged perpendicular to the gas distribution chamber and are simultaneously connected to the gas distribution chamber. When the inflation pump inflates the gas distribution chamber, it can simultaneously inflate the multiple horizontal inflation lines. The horizontal inflation lines can inflate multiple airbag modules located in the same row.
[0015] Furthermore, when the isolation air cushion group and the side-turning air cushion group located on the same side are inflated simultaneously, the self-turning adjustable anti-bedsore massage air cushion is raised on one side, and is in the side-turning mode; when the two isolation air cushion groups are inflated simultaneously, the patient can be restricted to the middle of the self-turning adjustable anti-bedsore massage air cushion, and is in the self-limiting mode; when the first airbag module, the second airbag module, the third airbag module, the sixth airbag module, the seventh airbag module, the eighth airbag module, the twelfth airbag module, the thirteenth airbag module and the fourteenth airbag module are inflated simultaneously, the self-turning adjustable anti-bedsore massage air cushion is in the sitting and lying mode; when the fourth airbag module, the fifth airbag module, the ninth airbag module, the tenth airbag module, the sixteenth airbag module and the seventeenth airbag module are inflated simultaneously, they are in the foot-lifting mode.
[0016] Furthermore, the vacuum pump is connected to the multiple horizontal inflation lines via the gas distribution chamber; and a pressure valve is installed between the vacuum pump and the gas distribution chamber to control the gas pressure inside the airbag module after inflation and deflation. This controls the inflation and deflation speed of the airbag, ensuring that unused airbags remain fully compressed.
[0017] Furthermore, both the primary and secondary solenoid valves are connected to a PLC controller. By adjusting the opening and closing states of the primary and secondary solenoid valves corresponding to each airbag module through the PLC controller, the overall shape of the self-turning adjustable body position anti-bedsore massage air cushion can be controlled.
[0018] The technical solution of this utility model can achieve at least one of the following effects:
[0019] 1. This utility model's self-turning adjustable anti-bedsore massage air mattress has a three-layer structure: the bottom layer is an anti-bedsore air mattress, the middle layer is a self-turning auxiliary air mattress, and the top layer is a massage pad that provides acupoint stimulation. It is equipped with an air pump and a vacuum pump for rapid inflation and deflation switching. A controller and multiple sets of solenoid valves control multiple airbag modules, enabling rapid switching between different airbag modules for inflation or deflation, thus adjusting the overall shape of the mattress and assisting patients in turning over and adjusting their sitting or lying posture.
[0020] 2. The self-turning adjustable body position anti-bedsore massage air cushion of this utility model can physically isolate the patient from the hospital bed through the air cushion. The patient can independently control different airbag modules to assist the patient in changing from a supine position to a lateral position, and from a lateral position to a supine or semi-recumbent position. The patient can also independently control the massage and acupoint stimulation system as needed, which can reduce the discomfort and complications of long-term bed rest without the help of the patient's family.
[0021] 3. The self-turning adjustable body position anti-bedsore massage air cushion of this utility model is designed with multiple sets of airbag modules arranged in an array. By independently controlling the multiple sets of airbag modules, they can switch between various combination modes after inflation and deflation, realizing the auxiliary adjustment of the patient's side turning, sitting, lying down, leg raising and other postures. It has multiple functional modes and is easy to adjust.
[0022] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing the invention.

Detailed Implementation
[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0033] Example 1
[0034] A specific embodiment of this utility model discloses a self-adjustable, bedpan-protective massage air cushion, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes: a gas diversion chamber 1, an air pump 2, a self-turning assist air cushion layer, a massage pad, an air cushion isolation layer 21, horizontal inflation lines 22, and vertical inflation lines 23; the massage pad is laid in the middle of multiple self-turning assist air cushion layers; each self-turning assist air cushion layer is composed of multiple arrayed airbag modules; the airbag modules expand after inflation, assisting the patient in adjusting their posture; the air cushion isolation layer 21 is located below the self-turning assist air cushion layer, and the horizontal inflation lines 22 and vertical inflation lines 23 are nested inside the air cushion isolation layer 21; the horizontal The inflation lines 22 are arranged in parallel and connected to the gas distribution chamber 1; multiple vertical inflation lines 23 are arranged in parallel on the horizontal inflation lines 22, and the vertical inflation lines 23 are perpendicular to the horizontal inflation lines 22; the number of vertical inflation lines 23 is the same as the number of airbag modules, and the two are interconnected and correspond one-to-one; a primary solenoid valve is provided at the end of the horizontal inflation line 22 connected to the gas distribution chamber 1, and a secondary solenoid valve is provided on the vertical inflation line 23; multiple airbag modules are independently controlled by multiple secondary solenoid valves to achieve independent inflation.
[0035] Specifically, the massage pad is an existing massage pad laid in the middle of the self-turning auxiliary air cushion layer; preferably, the massage pad and the self-turning auxiliary air cushion layer are bonded and fixed with Velcro; this facilitates regular cleaning and sterilization of the massage pad.
[0036] Specifically, such as Figure 2 , Figure 3 As shown, multiple horizontal inflation pipes 22 are arranged perpendicular to the gas distribution chamber 1 and are simultaneously connected to the gas distribution chamber 1. When the inflation pump 2 inflates the gas distribution chamber 1, it can simultaneously inflate the multiple horizontal inflation pipes 22.
[0037] Furthermore, by adjusting the opening and closing of the primary solenoid valves on the multiple horizontal inflation lines 22, it is possible to control whether gas enters the corresponding horizontal inflation line 22.
[0038] Furthermore, by adjusting the opening and closing of the secondary solenoid valve on the vertical inflation line 23, it is possible to control whether gas enters the corresponding airbag module.
[0039] Preferably, the self-turning adjustable anti-bedsore massage air cushion of this utility model is also equipped with a vacuum pump 24; the vacuum pump 24 is connected to the gas distribution chamber 1, and then connected to multiple horizontal inflation pipes 22 through the gas distribution chamber 1, for deflating (not completely evacuating) multiple sets of airbag modules. After deflating, the self-turning adjustable anti-bedsore massage air cushion is in a flat state.
[0040] In a preferred embodiment of this utility model, a pressure valve is provided between the vacuum pump 24 and the gas diversion chamber 1 to control the gas pressure inside the airbag module after inflation and deflation.
[0041] In practice, when the primary solenoid valve is opened, the horizontal inflation line 22 is connected to the gas distribution chamber 1, and the inflation pump 2 can inflate the horizontal inflation line 22; when the secondary solenoid valve is opened, the airbag module is connected to the horizontal inflation line 22 through the vertical inflation line 23, and the inflation pump 2 can inflate the corresponding airbag module; after the airbag module is inflated, it expands, thereby promoting the lifting of the corresponding limbs of the patient, realizing the posture adjustment of the bedridden patient. When in use, the patient can control the self-turning adjustable body position anti-bedsore massage air cushion of this utility model through the controller, and can turn over by himself without the help of others.
[0042] In one specific embodiment of this utility model, the self-turning auxiliary air cushion layer includes: a central air cushion group, an isolation air cushion group, and a side-turning air cushion group; the isolation air cushion group is disposed on both sides of the central air cushion group, and at least one group is disposed on each side; the side-turning air cushion group is disposed on the outside of the isolation air cushion group.
[0043] Furthermore, each of the central air cushion group, isolation air cushion group, and side rollover air cushion group is inflated and deflated through a horizontal inflation line 22.
[0044] Specifically, the multiple airbag modules include: a massage airbag module 6 located in the center, and a first airbag module 3, a second airbag module 4, a third airbag module 5, a fourth airbag module 7, a fifth airbag module 8, a sixth airbag module 9, a seventh airbag module 10, an eighth airbag module 11, a ninth airbag module 12, a tenth airbag module 13, an eleventh airbag module 14, a twelfth airbag module 15, a thirteenth airbag module 16, a fourteenth airbag module 17, a fifteenth airbag module 18, a sixteenth airbag module 19, and a seventeenth airbag module 20 located around the massage airbag module 6.
[0045] Specifically, the first airbag module 3, the second airbag module 4, and the third airbag module 5 are located in the same column as the massage airbag module 6, and are arranged vertically above the massage airbag module 6; the fourth airbag module 7 and the fifth airbag module 8 are located in the same column as the massage airbag module 6, and are arranged vertically below the massage airbag module 6; as shown Figure 1 As shown.
[0046] Furthermore, the first airbag module 3, the second airbag module 4, the third airbag module 5, the massage airbag module 6, the fourth airbag module 7, and the fifth airbag module 8 are arranged in a row to form a central air cushion group, and are connected to the same horizontal airbag line 22 through multiple vertical inflation lines 23.
[0047] Specifically, the sixth airbag module 9, the seventh airbag module 10, the eighth airbag module 11, the ninth airbag module 12, the tenth airbag module 13, and the eleventh airbag module 14 are arranged in a row and connected to the same horizontal inflation tube 22 to form an isolation air cushion group; the isolation air cushion group is located on both sides of the central air cushion group, with at least one row on each side.
[0048] Specifically, the twelfth airbag module 15, the thirteenth airbag module 16, the fourteenth airbag module 17, the fifteenth airbag module 18, the sixteenth airbag module 19, and the seventeenth airbag module 20 are arranged in a row and connected to the same horizontal inflation tube 22 to form a side-turning air cushion group; two groups of side-turning air cushions are symmetrically arranged and located on the outermost side of the self-turning adjustable body position anti-bedsore massage air cushion.
[0049] In one specific embodiment of this utility model, such as Figure 1 As shown, both the isolation air cushion group and the side roll air cushion group are located on the outside of the central air cushion group, and two groups are symmetrically arranged for each group.
[0050] like Figure 4As shown, when the isolation air cushion group and the side-turning air cushion group on the left side of the central air cushion group are inflated at the same time, the left side of the self-turning adjustable anti-bedsore massage air cushion is raised and is in the left-side turning mode; when the self-turning adjustable anti-bedsore massage air cushion is in the left-side turning mode, it can achieve the auxiliary effect of turning the patient to the left side.
[0051] Similarly, when the isolation air cushion group and the side-turning air cushion group on the right side of the central air cushion group are inflated at the same time, the right side of the self-turning adjustable anti-bedsore massage air cushion is raised and it is in the right-side turning mode; when the self-turning adjustable anti-bedsore massage air cushion is in the right-side turning mode, it can achieve the auxiliary effect of turning the patient to the right side.
[0052] Furthermore, such as Figure 1 As shown, when both sets of isolation air cushions are inflated simultaneously, they can confine the patient to the middle of the self-turning adjustable anti-bedsore massage air cushion, achieving a self-limiting function to prevent the patient from falling off the air mattress; at this time, it is in self-limiting mode.
[0053] Furthermore, such as Figure 5 As shown, when the first airbag module 3, the second airbag module 4, the third airbag module 5, the sixth airbag module 9, the seventh airbag module 10, the eighth airbag module 11, the twelfth airbag module 15, the thirteenth airbag module 16, and the fourteenth airbag module 17 are inflated simultaneously, the self-turning adjustable body position anti-bedsore massage air cushion is in a sitting or lying mode, which can help the patient be in a sitting or lying position with the upper body raised.
[0054] Furthermore, such as Figure 6 As shown, when the fourth airbag module 7, the fifth airbag module 8, the ninth airbag module 12, the tenth airbag module 13, the sixteenth airbag module 19, and the seventeenth airbag module 20 are inflated, they can lift the patient's feet. At this time, the self-turning adjustable body position anti-bedsore massage air cushion is in the foot lifting mode.
[0055] In one specific embodiment of this invention, to achieve independent control of multiple airbag modules and facilitate patient use, multiple solenoid valves are connected to a PLC controller. A control strategy is compiled in the PLC controller to control the air mattress to switch between several modes. When the self-turning adjustable anti-bedsore massage air mattress switches working modes, the PLC controller adjusts the state of the primary and secondary solenoid valves corresponding to each airbag module. Furthermore, multiple pressure valves are simultaneously connected to the PLC controller. The PLC controller controls the pressure values of these valves to regulate the internal pressure of the airbag modules after inflation and deflation, and simultaneously controls the overall shape of the self-turning adjustable anti-bedsore massage air mattress.
[0056] Using a PLC controller to control the opening and closing of multiple solenoid valves and switch between multiple control modes is a common application of PLC controllers, which is something that those skilled in the art can obtain from the prior art, and will not be elaborated upon in this utility model.
[0057] Example 2
[0058] A specific embodiment of this utility model provides a specific structural design for a self-turning adjustable body position anti-bedsore massage air cushion based on Embodiment 1:
[0059] In this embodiment, two sets of the isolation air cushion group are symmetrically arranged on the left and right sides of the central air cushion group; that is, two sets of the isolation air cushion group are arranged on one side of the central air cushion group, for a total of four sets.
[0060] During implementation, controlling the lifting of one or both of the two sets of isolation air cushions on both sides can achieve a self-limiting effect or a unilateral turning effect for bedridden patients, and has better adaptability for patients of different body types.
[0061] Preferably, the width of the central air cushion assembly is set to 30cm to 45cm.
[0062] Preferably, the width of the side-rolling air cushion assembly is set to 30cm to 40cm.
[0063] Preferably, the width of the isolation air cushion group is set to 10cm to 25cm.

[0066] In this embodiment, the self-turning adjustable anti-bedsore massage air cushion of this invention is also equipped with a remote control connected to the PLC controller. The remote control allows switching between several operating modes of the PLC controller. Signal transmission between the remote control and the PLC controller can be achieved using an infrared module, a Bluetooth module, or a wire cable. In practice, the patient only needs to operate the remote control to control the inflation of different airbag modules of the self-turning adjustable anti-bedsore massage air cushion, thereby assisting the patient in adjusting their posture.
[0067] This utility model features a self-turning adjustable body position anti-bedsore massage air cushion with a three-layer air cushion design. The bottom layer is an air cushion isolation layer that isolates the patient from the bed board and mattress to prevent bedsores. The second layer is a self-turning auxiliary air cushion layer, allowing the patient to manually control their bed position via a switch, freely switching between left and right sides, supine, and semi-recumbent positions to prevent lung infections and increase blood circulation. The third layer is a massage cushion that promotes muscle contraction and prevents osteoporosis caused by prolonged bed rest. It is equipped with an air pump 2, a vacuum pump 24, a solenoid valve, and a controller, allowing bedridden patients to adjust the position independently according to their needs without the assistance of caregivers or family members. Furthermore, this utility model uses air cushions of different shapes to achieve different body positions, ensuring safety and low cost, and better preventing various complications in bedridden patients.
