Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an inflatable angle-adjustable turning-over cushion device. Background Art

[0002] With the development of modern medical technology, more and more elderly people, long-term bedridden patients and patients recovering from surgery are facing a series of health problems caused by long-term lying, such as bedsores, muscle atrophy, poor blood circulation, etc. In order to alleviate these problems, the medical equipment field continues to explore more effective auxiliary devices. Turnover pads, as a common auxiliary device, have been widely used in patient care. Their main function is to help patients turn over regularly to avoid maintaining the same posture for a long time, thereby reducing the occurrence of bedsores and improving blood circulation.

[0003] After searching, it was found that the prior art publication number is CN 218792866U, which discloses an adjustable turning pad, including a soft pad layer, a first inflatable layer, a turning pad main body and a second inflatable layer. The turning pad is provided with a soft pad layer, a first inflatable layer, a turning pad main body and a second inflatable layer from top to bottom. The first inflatable layer and the second inflatable layer are independently provided with corresponding air inlet pipes and exhaust pipes. The air inlet pipes on the first inflatable layer and the second inflatable layer are connected to the corresponding external air supply device. The scheme selects to inflate the corresponding first inflatable layer and the second inflatable layer through the external air supply device to expand the first inflatable layer and the second inflatable layer, thereby changing the expansion degree by changing the amount of gas filled in the first inflatable layer and the second inflatable layer, and then adjusting the angle between the soft pad layer and the bed body, so that the patient can change the turning angle at any time during the turning process, thereby avoiding pressure sores caused by turning at a single angle for a long time.

[0004] Therefore, based on the above search and in combination with the existing technology, when the above solution is used, the turning pad directly lifts one side of the patient, and the force is relatively concentrated, which may not maintain sufficient stability, causing the patient to easily slide or become unstable during the turning process, especially when the patient is not fully supported during the turning process, which may easily cause the patient to feel uncomfortable, slip or fall, etc. Accidents, especially for patients with fractures, spinal problems or spinal cord injuries, sudden movements may cause injuries, and the practicality is not strong.

Specifically, a through hole is opened at the center of the movable block 303, and the end of the transmission rod 302 close to the movable block 303 is spherical and clamped in the through hole at the center of the movable block 303. An abutment plate 305 is slidably installed on the inner end of the inner tube 301, and the abutment plate 305 is located below the movable block 303. The bottom end of the abutment plate 305 is fixedly connected with a movable tube 306, and the movable tube 306 is inserted into the inner tube 301. A micro-motion sensor (model such as XCE145) is fixedly installed at the inner end of the inner tube 301. The specific working principle is an existing mature technology and will not be elaborated here. It is used to detect the movement state of the movable tube 306, and the micro-motion sensor is connected to the control terminal through a signal line. The abutment plate 305 and the inner tube 301 are connected through a reset spring 308, and the reset spring 308 is sleeved on the outer surface of the movable tube 306.

[0036] A rectangular hole is provided on the outer surface of the inner movable cylinder 104, and a force-bearing plate 108 is passed through the rectangular hole. A limit plate is fixedly installed in the rectangular hole, and the limit plate can prevent the force-bearing plate 108 from escaping from the inner movable cylinder 104, and the force-bearing plate 108 can move left and right in the rectangular hole. A sealing rubber ring is sleeved on the outer surface of the force-bearing plate 108, and the sealing rubber ring fits tightly in the rectangular hole to increase air tightness. A force-bearing sheet 110 is slidably installed on the inner end of the force-bearing plate 108, and a sealing rubber ring is also fixedly sleeved on the outer surface of the force-bearing sheet 110, and fits tightly with the inner wall of the force-bearing plate 108 to increase air tightness.

The inner end of the inner tube 301 is fixedly installed with an arc plate 111, and the outer surface of the force-bearing sheet 110 contacts the inner wall of the arc plate 111. Then, when the air pressure outside the protective cover becomes high, only the right end of the force-bearing sheet 110 can move toward the left side under the action of pressure and push the force-bearing sheet 110 to move. The arc plate 111 converts the force transmitted by the force-bearing sheet 110 into a downward direction by virtue of its own bending characteristics.

[0037] A through hole is provided on the outer surface of the inner movable cylinder 104, and a bellows 107 is passed through the through hole. The left end of the bellows 107 is fixedly connected to the inner tube 301, and the right end is fixedly connected to the inner wall of the support cylinder 6. An air outlet is provided on the outer wall of the support cylinder 6, and the air outlet is communicated with the bellows 107. An air leakage hole 307 is provided on the outer surface of the inner tube 301, and the air leakage hole 307 is communicated with the bellows 107. The bellows 107 is made of polypropylene and has certain pressure resistance and excellent anti-folding and anti-aging properties. Specifically, a switch tube 304 is fixedly installed on the bottom end of the movable block 303, and the switch tube 304 is passed through the inside of the movable tube 306. A rectangular groove is provided on the outer surface of the switch tube 304, and a rectangular block is fixedly installed inside the movable tube 306. The rectangular block is arranged in the rectangular groove, so that the switch tube 304 cannot rotate during the up and down movement, and a sealing gasket is fixedly sleeved on the outer surface of the switch tube 304 to increase air tightness;

[0038] An extension piece is fixedly installed at the bottom end of the on-off tube 304, and the extension piece corresponds to the bleed hole 307. When the movable block 303 moves upward, it will pull the on-off tube 304 upward, and the movable block 303 will be separated from the interior of the inner tube 301, and a certain gap will be retained between the on-off tube 304 and the inner tube 301. The on-off tube 304 will be separated from the interior of the movable tube 306, while the extension piece will still be inside the movable tube 306 and block the bleed hole 307.

[0039] like Figure 4 , Figure 8 , Fig. 9As shown, the sensing device includes a piston 204, which is slidably connected to the inside of the detection cylinder 201. A sealing rubber ring is fixedly sleeved on the outer surface of the piston 204, and the sealing rubber ring is tightly fitted with the inner wall of the detection cylinder 201 to increase the sealing performance. The chamber below the piston 204 is filled with hydraulic oil, and a vent is also provided at the upper end of the detection cylinder 201. A limit ring is fixedly installed at the inner end of the detection cylinder 201, and the limit ring is located below the piston 204. A center rod 202 is fixedly installed at the inner upper end of the detection cylinder 201, and a spiral groove is provided on the outer surface of the center rod 202, and the piston 204 is sleeved on the outer surface of the center rod 202, and a convex block is fixedly installed at the inner end of the piston 204, and the convex block is clamped in the spiral groove. Then, when When the hydraulic oil under the piston 204 increases, the piston 204 is pushed upward under the action of pressure, and the piston 204 can also rotate during the upward movement. Specifically, a contact block 203 is fixedly installed on the upper end of the piston 204, and the contact block 203 contacts the inner wall of the detection cylinder 201. The center rod 202, the piston 204 and the contact block 203 are all made of metal and have good conductive properties. A spiral resistor (not shown in the figure) is fixedly installed on the inner wall of the detection cylinder 201, and the contact block 203 contacts the inner wall of the spiral resistor. The spiral resistor and the center rod 202 are connected to the control terminal through wires. When the piston 204 moves upward, the control terminal can detect the change in resistance value.

[0040] The outer surface of the detection cylinder 201 is fixedly connected with a synchronous tube 101, which is connected to the chamber below the piston 204, and the free end of the synchronous tube 101 is fixedly connected to the bottom end of the support cylinder 6 when passing through the bottom of each support cylinder 6. The synchronous tube 101 is parallel to the pad 2. Specifically, the synchronous tube 101 is connected to the chamber below the inner movable cylinder 104 inside the support cylinder 6, and the chamber below the inner movable cylinder 104 is also filled with hydraulic oil. The chamber capacity inside the detection cylinder 201 is the sum of the chamber capacities below a row of inner movable cylinders 104. More specifically, a solenoid valve is fixedly installed at the entrance of each horizontal synchronous tube 101, and the solenoid valve is connected to the control terminal through a wire.

[0041] If the patient needs to turn over, the inner movable cylinder 104 along the human body contour line is pushed upward by the elastic force of the micro-spring 106, and then the hydraulic oil inside the detection cylinder 201 is extracted. At this time, the piston 204 starts to move, and the resistance value changes. When the resistance value change reaches the preset turning over requirement, the control terminal then controls the air pump 3 to start working, and then inflates the airbag 9. When the angle reaches a suitable angle, the patient only needs to apply force in the opposite direction of the turning up direction of the pad 2. At this time, it is detected by the micro-sensor, and the air pump 3 stops working. To achieve the above operation, the following methods are cited;

[0042] When the resistance value changes and reaches the predetermined resistance value, set R current is the current resistance value, and the turning demand triggering condition can be expressed as:

[0043] ΔR=R current -R initial ≥R threshold

[0044] , when this condition is met, the air pump 3 starts to work and inflates the airbag 9;

[0045] When the turning angle reaches the preset appropriate angle (set as θ desired ), the patient needs to apply a force (F reverse ) to further control the turning over and ensure that the turning pad remains stable. The reverse force is applied by the patient and detected by the micro-motion sensor. When the reverse force reaches the set standard (set as F reverse ≥F thres h old ), the air pump 3 stops inflating, and the conditions for stopping inflating are:

[0046] F reverse ≥F threshold andθ=θ desired

[0047] At this time, the air pump 3 stops working and the entire turning process is completed. It is worth noting that all the above-mentioned calculation tasks are calculated by the processor inside the control terminal.

[0048] The working principle of the present invention is:

[0049] When the patient lies on the cushion board 2, the inner movable cylinder 104 along the human body contour and completely covered by the human body moves downward, and the support cover 103 at the human body contour is in a tilted state. At this time, when the support cover 103 is tilted, the transmission rod 302 drives the on-off tube 304 to move upward. When the movable block 303 moves upward, it pulls the on-off tube 304 to move upward. At this time, the on-off tube 304 will be separated from the inside of the movable tube 306, and a certain gap will be kept between the movable block 303 and the inner tube 301. A certain gap is kept between the movable block 303 and the inner tube 301, and the extension piece is still inside the movable tube 306 and blocks the air leakage hole 307.

[0050] If the patient needs to turn over, the inner movable cylinder 104 moves upward along the contour of the human body, and the control terminal can know which area has changed the resistance value. The solenoid valve inside the synchronous tube 101 in the area of ​​the changed resistance value is in an open state, and the real-time control terminal can operate the air pump 3 to start working. Then the gas passes through the gas delivery pipe 5 to the inside of the inner tube 301, and then flows out through the gap between the on-off pipe 304 and the movable tube 306 and between the movable block 303 and the inner tube 301, and finally flows through the outlet pipe 102 to the inside of the airbag 9, and then the pad 2 will be lifted;

[0051] Then, during the lifting process, since the human body is always pressing the pad 2, under the action of the human body's own gravity, the inner movable cylinder 104 at the center is initially lifted by one side of the human body, and the support cover 103 above the inner movable cylinder 104 originally inside the human body contour line is also in a tilted state, so the inner movable cylinder 104 originally inside the human body contour line also begins to move slightly upward, and the secondary lifting begins (such as Fig. 9 As shown in the figure, if the patient feels that the current angle reaches the expected one, he only needs to apply a force in the opposite direction of the lifting. At this time, the airbag 9 is pressed and transmits the internal pressure to the inside of the support tube 6 through the air outlet pipe 102. The pressure inside the support tube 6 increases suddenly, causing the force-bearing sheet 110 to move to the left, and the abutment plate 305 is pressed downward through the transmission sheet 109, which is then detected by the micro-motion sensor (the micro-motion sensor does not send a signal for the initial movement of the active tube 306), and the air pump 3 stops working;

[0052] If the patient needs to lie flat, a certain amount of pressure is applied toward the back again, so that the force-bearing plate 110 continues to move to the left, and the abutment plate 305 is driven downward through the transmission plate 109, so that the air leakage hole 307 no longer corresponds to the extension plate under the on-off tube 304. At this time, the air inside the airbag 9 flows in through the air leakage hole 307, passes through the bellows 107, and then flows out through the air holes on the outer surface of the support tube 6. At this time, the patient can return to the lying flat state.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
