Description

Technical Field

[0001] The invention belongs to the technical field of nursing appliances, and in particular relates to a left-right alternating electric inflatable turning pillow. Background Art

[0002] Patients who are bedridden for a long time are often at risk of skin pressure sores because they cannot move their bodies independently. The important principle for preventing and treating pressure sores is to relieve the continuous pressure on the local pressure area and promote local blood circulation. Turning over is the simplest and most effective preventive measure. However, the traditional way of turning over requires manual operation, which is inefficient and easy to cause injury to the patient. Patients who are bedridden for a long time need to turn over at least once every two hours. The hard sponge triangular turning pillow currently used requires two people to work together to turn over, and it is easy to be flattened after long-term use or for patients with heavy weight.

[0003] Due to long-term bed rest, the patient's coccyx or occipital protuberance with thinner skin and flesh is compressed, causing local tissue ischemia, hypoxia and necrosis, which may form bedsores. When turning over, the side-lying position should be at least 30 degrees to ensure blood circulation. In severe cases, the side-lying position should be more than 60 degrees to prevent the formation of bedsores.

[0004] The existing air cushion type usually adopts a one-piece structure. By inflating the one-piece air cushion, one end becomes higher, so as to realize the turning action of the bedridden patient. The principle of this is to change the force on the patient's back. When turning over, the center of gravity changes, and the force surface of the side is smaller, so that the blood in the rest of the body can circulate. Therefore, the principle of turning over is to change the center of gravity to make the force surface smaller and increase the area of ​​blood circulation. However, when the one-piece air cushion supports the patient to turn over, in order to prevent the angle of the patient's body position from being too large, a smaller angle is usually selected. However, in this way, the center of the patient does not change much, and the blood circulation effect in the back area is not good. The left and right alternating turning pad usually has a very high air cushion near the edge of the bed. When the turning pad is raised to change the side-lying position of the bedridden patient, the height change near the patient's body side is small, and the height change near the edge of the bed is large. This not only leads to a poor turning effect of the patient, but also causes inconvenience when caring for the patient from the edge of the bed.

[0005] Therefore, the present invention proposes a left-right alternating electric inflatable turning pillow, which aims to realize automatic turning of the patient, achieve a better turning effect and facilitate nursing care for the patient during turning. Summary of the invention

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] like Figure 1-Figure 5 As shown, a left-right alternating electric inflatable turning pillow includes an air cushion 1, an inflation and deflation module 2 and a lifting module 3; the inflation and deflation module 2 is used to inflate and deflate the air cushion 1 and the lifting module 3; the inflation and deflation module 2 is the control center of the entire system, responsible for providing the required gas pressure or releasing gas to the air cushion 1 and the lifting module 3. First, the air cushion 1 needs to be filled with gas, and then the inflation amount in the lifting module 3 needs to be changed. The special inflation and deflation module 2 controls the flow of gas through a preset program or external operating instructions (such as a remote control, a control panel, etc.). When an inflation instruction is received, the inflation and deflation module 2 starts, pumps air into the designated lifting module 3, lifts the air cushion 1, and realizes the patient's body position reversal; when a deflation instruction is received, the gas in the lifting module 3 is sucked out, and the lifting end of the air cushion 1 drops;

[0031] The air cushion 1 includes a main cushion 11, a support cushion 12, a left cushion 13 and a right cushion 14; the support cushion 12 is arranged in the middle of the main cushion 11, and the left cushion 13 and the right cushion 14 are respectively arranged on both sides of the support cushion 12 to form a complete support surface. The support pad 12 is located in the middle of the main pad 11, and plays a role of stable support; the left pad 13 and the right pad 14 are arranged at intervals, and the left pad 13 and the right pad 14 are respectively located on both sides of the support pad 12, and are arranged at intervals. They can be adjusted by inflation and deflation as needed, and can realize the left and right alternating lifting of the air cushion 1, thereby realizing the left and right turning of the bedridden patient. Because the patient's lifting angle is less than 90°, the patient also needs to support the lifted seat cushion or the right pad 14 while turning over. For example, when the lifting module 3 connected to the left pad 13 is inflated, the angle between the seat cushion and the patient will change, thereby turning the patient over. At the same time, the bedridden patient also needs to rely on the left pad 13. Therefore, the left pad 13 is arranged at an interval with a little, so that the air cushion 1 is in a flat state when the patient is not lifted, and the interval setting can reduce the contact area between the patient and the left pad 13 when changing the patient's lateral position, thereby improving the patient's blood circulation and reducing the situation of pressure sores; similarly, the lifting principle of the right pad 14 is the same as that of the left pad 13, which will not be repeated;

[0032] The left pad 13 and the right pad 14 both include an equally divided first airbag 41 and a second airbag 42; the lifting module 3 is arranged at the connection between the first airbag 41 and the second airbag 42 through the adjustment component 5, and the lifting module 3 is arranged vertically with the main pad 11; the lifting module 3 supports the left pad 13 and the right pad 14 respectively from the vertical direction to form a variable arc structure, so that relative to the triangular turning pad structure, its highest point is at the edge of the bed, and the lowest point is close to the patient's torso. The height change of the lowest point relative to the highest point is very small, and it is difficult to achieve a significant change in the patient's lateral position, so that the pressure area of ​​the patient's back changes slightly, thereby improving the blood flow to the back. The ventilation effect is not obvious, and a large amount of gas needs to be filled in to change the patient's lateral position. At the same time, when the inflation volume increases, the height of the bed edge will become higher, which is not conducive to the nursing work of the nursing staff for the bedridden patient. Therefore, the lifting module 3 is arranged between the first airbag 41 and the second airbag 42, and the patient is located in the middle area of ​​the support cushion 12 and lying on the air cushion 1. When the patient's left side is lifted, the lifting module 3 located in the left cushion 13 area is inflated. At this time, the inflation volume in the lifting module 3 increases, and the height gradually increases from the main cushion 11 upwards. While rising, the first airbag 41 and the second airbag 42 are lifted. Because the first airbag The ends of the first airbag 41 and the second airbag 42 are fixed on the main cushion 11. Therefore, under the action of the lifting module 3, the angles of the first airbag 41, the second airbag 42 and the main cushion 11 change, and the whole presents an arc structure. The angle of the first airbag 41 changes while changing the patient's lateral position. At the same time, since the highest point of the arc is located at the position of the lifting module 3, and the lengths of the first airbag 41 and the second airbag 42 of the present application are the same, the highest point is located in the middle of the patient and the edge of the bed. Compared with the existing highest point located at the edge of the bed, the first airbag 41, under the action of the lifting module 3, the angle between the first airbag 41 and the main cushion 11 changes, and the height of the lifting The degree of change is more obvious, and the corresponding effect of achieving a better lateral lying position for the patient is better. When turning over is required, the inflation and deflation module 2 first controls the inflation of the lifting module 3 to make it the highest point and located between the patient and the edge of the bed. Then, the inflation amount of the air bag of the left pad 13 or the right pad 14 is adjusted as needed to make the patient's body tilt to one side. With the support of the lifting module 3 and the adjustment of the air bag, the patient can easily complete the turning action. Since turning over becomes more frequent and easier, the risk of pressure sores for patients is significantly reduced, and the overall quality of nursing is improved. In addition, the design of the turning pillow also helps to reduce the workload of nursing staff and improve work efficiency.

[0033] In one embodiment, the lifting module 3 and the first airbag 41 form a supporting part for supporting the patient, and the slope of the supporting part changes with the height of the lifting module 3; the first airbag 41 is close to the main cushion 11, and the second airbag 42 is close to the edge of the bed. The lifting module 3 and the second airbag 42 form an auxiliary part for caring for patients.

[0034] In one embodiment, the lifting module 3 includes a third airbag 31 and a plurality of snap-in strips 32; the plurality of snap-in strips 32 are arranged in an array at the upper end of the third airbag 31, the plurality of snap-in strips 32 are hinged to the third airbag 31, and the plurality of snap-in strips 32 are at least arranged on two sides of the third airbag 31; the adjustment component 5 includes an outer sheath 511 sleeved on the third airbag 31 and a rotating tooth 512 rotatably mounted on the sheath 511, a rotating tooth 512 meshing with a plurality of snap-in strips 32 on one side to form a snap-in part 51 of the third airbag 31, the amount of inflation in the third airbag 31 drives the snap-in strip 32 at the bottom to rotate upward and drives the rotating tooth 512 to rotate and mesh with the adjacent snap-in strip 32 at the upper part; when not inflated, the third airbag 31 remains flat, and the plurality of snap-in strips 32 at its upper end are arranged in an array and hinged to the airbag, and these snap-in strips 32 are distributed on at least two sides of the airbag (such as the front and back or the left and right sides) so as to provide a snap-in strip 32 when inflated. All-round supporting force. When the third airbag 31 is inflated, the airbag gradually expands and expands upward. The clip strip 32 at the bottom of the airbag is first subjected to pressure and begins to rotate upward around the hinge point. This rotation action not only causes the clip strip 32 itself to change position, but also produces meshing action with the rotating teeth 512 through its toothed structure. As the bottom clip strip 32 rotates, the rotating teeth 512 meshing therewith also rotates accordingly. The installation position of the rotating teeth 512 ensures that it can mesh with the upper, adjacent clip strips 32 in turn, forming a continuous, gradually rising driving mechanism. This mechanism enables the clip strip 32 to be lifted step by step like a step, thereby driving the entire third airbag 31 and the load thereon to rise steadily. During the entire lifting process, the meshing action between the clip strip 32 and the rotating teeth 512 and the firm support of the outer sheath 511 to the rotating teeth 512 ensure the smoothness and reliability of the lifting action. At the same time, the distribution of the clip strips 32 on both sides of the airbag enhances the uniformity of the lifting force and prevents tilting or instability caused by excessive force at a single point; the meshing mechanism between the clip strips 32 and the rotating teeth 512 ensures the stability and reliability of the lifting process, and can maintain a smooth lifting action even in the event of load changes or external environmental interference, and the third airbag 31 is in a stable state at different inflation volumes, thereby enabling the left pad 13 and the right pad 14 to be lifted.

[0035] In one embodiment, the adjustment component 5 also includes a connecting plate 52, a first extension plate 53 and a second extension plate 54; the connecting plate 52 is fixedly connected to the sheath 511, one end of the first extension plate 53 is hinged to the first airbag 41, and the other end is connected to the connecting plate 52; one end of the second extension plate 54 is hinged to the second airbag 42, and the other end is connected to the connecting plate 52; the first extension plate 53 and the second extension plate 54 slide on the connecting plate 52 to compensate for the length of the first airbag 41 and the second airbag 42 after being lifted; in order to adapt to the changes brought about by the lifting module 3, the first airbag 41 and the second airbag 42 are lifted as the lifting module 3 is lifted. The extension plates are connected in a hinged manner, and the first airbag 41 and the second airbag 42 can adapt to the changes of the lifting module 3 through the adjustment component 5. Specifically, when the first airbag 41 and the second airbag 42 change, they can drive the extension plate to slide on the connecting plate 52, so that the distance between the first airbag 41 and the second airbag 42 and the lifting module 3 becomes longer and the position is adaptively adjusted, thereby compensating for the length change caused by the lifting module 3; the connecting plate 52 serves as the core supporting structure of the entire adjustment component 5, which not only fixes the initial position of the extension plate, but also provides a stable support platform for the entire device through its fixed connection with the sheath 511.

[0036] In one embodiment, the ends of the left pad 13 and the right pad 14 are both provided with a blocking portion 15 passing through the support pad 12, and the blocking portion 15 is communicated with the connected left pad 13 and the right pad 14, and the blocking portion 15 is rotatably connected to the support pad 12, and is used for supporting from the lifting end away from the air cushion 1; that is, when the left pad 13 is lifted to change the patient's lateral position, the patient's torso located on the left pad 13 will be lifted. Once the rotation angle is too large and there is no support at the other end that is not lifted, the patient may roll over, causing the mouth and nose to face downward, which is easy to suffocate. The blocking portion 15 is provided at the ends of the seat cushion and the right pad 14. When the left pad 13 is lifted, due to the pressure on the left pad 13, part of the gas flows to the blocking portion 15. At this time, the blocking portion 15 will also rotate to the side close to the patient to support the patient. The blocking portion 15 can provide additional support to the patient from a position away from the lifting end of the air cushion 1, effectively preventing the patient from sliding or falling, and enhancing the safety and stability of use. Similarly, the blocking portion 15 connected to the right pad 14 and the blocking portion 15 connected to the left pad 13 are based on the same principle and will not be repeated.

[0037] In one embodiment, the support cushion 12 is a structure with a plurality of connection holes 121 at the bottom. The connection holes 121 are used to install the blocking part 15. The blocking part 15 is closely connected to the support cushion 12 through these connection holes 121 to form a stable and adjustable support system. When the air cushion 1 is inflated and used, the blocking part 15 can effectively provide additional support for the patient from a position away from the lifting end of the air cushion 1 to prevent side slipping or falling. The blocking part 15 is firmly installed on the support cushion 12 through the connection holes 121 to form a stable support structure. This design ensures that the blocking part 15 will not loosen or fall off during use, providing reliable support for the patient. The effective support and stable structure of the blocking part 15 significantly enhance the safety of the air cushion 1. It effectively prevents the risk of side slipping or falling of the patient during use, and provides a safer and more comfortable rehabilitation environment for the patient.

[0038] In one embodiment, the left pad 13 and the right pad 14 have the same structure. Both the left pad 13 and the right pad 14 are formed by a plurality of air columns arrayed on the main pad 11. The main pad 11 is fixedly connected to the lower side of the end of the air column. The left pad 13 and the right pad 14 are formed by the same number of air column arrays, ensuring their consistency in support force. This design avoids the discomfort caused by uneven support during use of the patient and improves the comfort of use. The left pad 13 and the right pad 14 can be used alternately, and the patient who needs to lie on his side can turn over to the left and right, increase blood circulation in the back, and reduce pressure sores. The left pad 13 and the right pad 14 have the same structure, which simplifies the mold design and manufacturing process in the production process and reduces production costs. At the same time, the consistent structure also makes subsequent maintenance and replacement of parts more convenient and quick.

[0039] In one embodiment, the inflation and deflation module 2 includes an air pump and a left air inlet pipe 21, a right air inlet pipe 22, an upper air inlet pipe 23 and an upper air outlet pipe 24 which are arranged on the main cushion 11 and connected to the air pump; the air pump is used for inflation and exhaustion; the left air inlet pipe 21 and the right air inlet pipe 22 are both provided with a plurality of branch openings for connecting air columns; the upper air inlet pipe 23 inflates the third airbag 31, and the upper air outlet pipe 24 is used for exhausting air into the third airbag 31; there are two upper air inlet pipes 23 and two upper air outlet pipes 24, one for connecting the third airbag 31 on the right, and the other for connecting the third airbag 31 on the left, for alternating inflation and deflation of the left cushion 13 and the right cushion 14; the air pump, as the core component of the inflation and deflation module 2, is responsible for generating and regulating gas pressure. In the inflation mode, the air pump compresses the external air and sends it into each air pipe; in the exhaust mode, the air pump exhausts the internal air through a specific air pipe; the left air intake pipe 21 and the right air intake pipe 22 are both provided with a plurality of branch ports, which are used to connect the air columns located under the main cushion 11. When the air pump inflates air through the air intake pipe, the air can be evenly distributed to each air column, so that they expand and support the main cushion 11. Similarly, when deflation is required, the air pump can achieve it through the reverse operation of these air inlet pipes; the upper air inlet pipe 23 and the upper air outlet pipe 24 are respectively used to inflate and deflate the third airbag 31. Since the third airbag 31 is distributed on the left and right sides of the main cushion 11 (such as the lifting module 3 in the left cushion 13 and the right cushion 14), the upper air inlet pipe 23 and the upper air outlet pipe 24 are each provided with two, one connected to the third airbag 31 on the right, and the other connected to the third airbag 31 on the left. This design ensures that the third airbags 31 on the left and right sides can be inflated and deflated independently and synchronously, thereby realizing the alternating operation of the left cushion 13 and the right cushion 14; by controlling the working mode of the air pump and the switching status of each air pipe, the alternating lifting of the left cushion 13 and the right cushion 14 (i.e., the third airbags 31 on the left and right sides) can be realized. For example, when the left side of the patient needs to be lifted, the upper air inlet pipe 23 of the third airbag 31 on the right side can be closed and its upper air outlet pipe 24 can be opened to evacuate air, while the upper air inlet pipe 23 of the third airbag 31 on the left side can be opened to inflate; vice versa, this alternating inflation and deflation method can flexibly adjust the supporting force and position distribution of the main cushion 11. This embodiment is only to illustrate that the air cushion has the inflation and deflation function, as long as inflation and deflation can be achieved.

[0040] In one embodiment, it also includes an intelligent adjustment module, which is provided with a timing module and a main control module; the main control module is electrically connected to the air pump, and the timing module is provided with the inflation time of the left pad 13 and the right pad 14, and uploads the inflation time to the main control system, and the main control system sends instructions to the air pump to alternately lift the left pad 13 and the right pad 14 according to the inflation time; the timing module uploads the set inflation time to the main control module, and after the main control module receives the time parameter, it generates a corresponding control instruction according to a preset logic algorithm; the main control module communicates with the air pump through an electrical connection, and sends the generated control instruction to the air pump, and the air pump adjusts its working mode according to the received instruction, and controls the corresponding air inlet and outlet pipes to realize the alternating lifting of the left pad 13 and the right pad 14; under the guidance of the control instruction, the air pump first lifts the left pad 13 according to the set time to lift it to a certain height. When the inflation time of the lifting module 3 of the left pad 13 reaches the preset value, the main control module sends an instruction to the air pump to stop inflating the lifting module 3 of the left pad 13, and start to lift the right pad 14. At the same time, if the left pad 13 needs to be deflated to restore the original position, the main control module will also send a corresponding air extraction instruction to the air pump. Through this alternating inflation and deflation method, the alternating lifting of the left pad 13 and the right pad 14 is achieved. Under the guidance of the control instruction, the air pump first inflates the left pad 13 according to the set time to lift it to a certain height. When the inflation time of the left pad 13 reaches the preset value, the main control module sends an instruction to the air pump to stop inflating the left pad 13 and start to inflate the right pad 14. At the same time, if the left pad 13 needs to be deflated to restore the original position, the main control module will also send a corresponding air extraction instruction to the air pump. Through this alternating inflation and deflation method, the alternating lifting of the left pad 13 and the right pad 14 is achieved.
