Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an anti-pressure sore auxiliary turning device and application thereof in patient care. Background Art

[0002] For patients who are bedridden for a long time, pressure sores are a hidden crisis. Due to long-term bed rest, the body's tissues are compressed, which leads to obstruction of subcutaneous blood flow and long-term ischemic changes, causing compressive necrosis of tissues. Therefore, regular turning over is essential for patients who are bedridden for a long time.

[0003] Considering that long-term bedridden patients have limited mobility, they are unable to turn over independently. At the same time, related medical devices are often unable to achieve a complete turning action well, and most of them can only play an auxiliary effect. After turning over, the patient's chest will also be compressed, causing difficulty in breathing.

[0004] To this end, in the prior art, most triangular flexible support blocks are used to support the patient's back, so that the patient forms a lateral tilting position. At this time, the pressure on the patient's back is reduced, which has a certain effect in preventing pressure sores. However, in actual use, this method is not convenient, mainly because in the lateral tilting position, only one side of the patient's back has reduced pressure, while the other side has an increasing pressure. In order to alleviate this phenomenon, the patient needs to cyclically tilt both sides, that is, the triangular flexible support block needs to be replaced, which is cumbersome to operate, and relative sliding is prone to occur between the triangular flexible support block and the bed body, resulting in unstable support.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0031] See also Figure 1 to Figure 11 , an anti-pressure sore auxiliary turning device provided in an embodiment of the present invention includes: a bed body 1, a turning plate 3, a side plate 4, a power component and a supporting structure.

[0032] The bed body 1 is provided with a hollow groove 2, and the hollow groove 2 is formed with an engaging groove 201 at both ends along the length direction thereof; The flip plate 3 is arranged on the bed body 1, and the flip plate 3 is provided with an engaging shaft 301 adapted to the engaging groove 201. In detail, the engaging shaft 301 is arranged on both sides of the flip plate 3. When one side of the flip plate 3 is lifted up, it can make a circular motion with the engaging shaft 301 on the other side as the center, and realize upward deflection, so that the patient's body tilts to the side. At this time, the center of gravity of the patient is tilted toward one side, so that one side of the patient's body is subjected to greater pressure, and the other side is subjected to less pressure. At this time, the side subjected to less pressure is relaxed, thereby preventing the side from producing pressure sores. At the same time, when the other side of the flip plate 3 is lifted up, the flip plate 3 can realize the flipping of the other side, so that the load-bearing size of both sides of the patient's body is switched, so that the other side of the patient is relaxed, and the two states are repeated in a cycle to reduce the occurrence of pressure sores in patients.

[0033] The power assembly is arranged on the bed body 1, and the power assembly includes a driving structure and a guide plate 9. The driving structure cooperates with the guide plate 9 to enable the flip plate 3 to deflect relative to both sides of the bed body 1, wherein the driving structure includes an electric telescopic rod 10 symmetrically and rotatably mounted on the bed body 1, and an abutment roller 8 is rotatably mounted on the action end of the electric telescopic rod 10; The driving structure further comprises a connecting plate 6 fixedly connected to the flip plate 3, the connecting plate 6 is provided with a slide groove 601, a slider 7 is slidably installed in the slide groove 601, and the slider 7 is rotatably connected to the abutting roller 8; The upper end of the guide plate 9 is provided with a first horizontal surface 901 , and first inclined surfaces 902 are provided on both sides of the first horizontal surface 901 . When the abutting roller 8 moves from the first horizontal surface 901 to the first inclined surface 902 , one side of the flip plate 3 can be deflected upward.

[0034] In the initial state, the upper surface of the flip plate 3 is coplanar with the upper surface of the bed body 1. At this time, the upper surface of the bed body 1 is flatter, so that the device can be used as an ordinary bed in the non-pressure sore prevention state. In the initial state, the abutment roller 8 is in the middle position of the first horizontal plane 901. When the electric telescopic rod 10 is actuated, it can drive the slider 7 to move along the length direction of the slide groove 601. At this time, the abutment roller 8 will move along the first horizontal plane 901, and when the abutment roller 8 moves to the first inclined surface 902, the abutment roller 8 will tilt upward. In this state, the abutment roller 8 is on one side of the central axis of the flip plate 3, and when the abutment roller 8 moves along the first inclined surface 902, the flip plate 3 can make a circular motion with the interlocking shaft 301 on the other side as the center, thereby assisting the patient to tilt, so that the pressure on the upper part of the patient in the tilting state is smaller, and the pressure on the lower part is larger, thereby reducing the pressure on the upper part of the patient in the tilting state and preventing the occurrence of pressure sores.

[0035] When the electric telescopic rod 10 moves in the reverse direction, the abutment roller 8 can be reset to the first horizontal plane 901 along the first inclined surface 902. At this time, the flip plate 3 returns to a state coplanar with the upper surface of the bed 1, and when the electric telescopic rod 10 continues to move, the other side of the flip plate 3 will flip upward again, thereby driving the patient to tilt in the opposite direction. That is, in the process of repeated movements of the electric telescopic rod 10, the flip plate 3 can drive the patient's limbs to tilt back and forth, so that both sides of the patient's body can bear weight cyclically, and reduce the pressure on the limbs on the other side when one side bears weight, thereby having a certain effect of preventing pressure sores.

[0036] Through the above arrangement, when the electric telescopic rod 10 is in motion, it can drive the abutting roller 8 connected thereto to move along the length direction of the slide groove 601, and in the process of the abutting roller 8 cooperating with the two groups of first inclined surfaces 902, the flip plate 3 is driven to perform cyclical reciprocating flipping. At this time, the patient's body can be driven to tilt reciprocatingly, achieving the effect of enabling both sides of the patient's body to bear weight cyclically, while reducing the pressure on the limbs on the other side when one side bears weight, thereby having a certain effect of preventing pressure sores.

[0037] See also Figure 5 , Figure 7 The bed body 1 is also provided with a pillow portion 5 that can be raised and lowered. The pillow portion 5 penetrates the bed body 1 and is connected to a connecting plate 12. The connecting plate 12 is provided with a first transverse groove 1201 along its length direction; A groove wheel 11 coaxially arranged with the abutting roller 8 is rotatably mounted on the action end of the electric telescopic rod 10 , and the groove wheel 11 is in rolling cooperation with the first transverse groove 1201 .

[0038] When the abutment roller 8 moves along the first inclined surface 902, the rotation center of the abutment roller 8 will rise in the vertical direction of the space. At this time, the groove wheel 11 coaxially arranged therewith will also rise in the vertical direction of the space. When the groove wheel 11 cooperates with the first transverse groove 1201, the connecting plate 12 can drive the pillow part 5 to move vertically upward, thereby supporting the patient's head in the tilted state and preventing the patient's neck from bending at a large angle and causing discomfort.

[0039] See also Figure 6 , Figure 8 The side panels 4 are provided in two groups and are rotatably mounted on the bed body 1; The support structure is connected to the driving structure and the side panels 4. The support structure can drive one group of the side panels 4 to deflect upward before the flip panel 3 deflects. In the initial state, the side panels 4 are also coplanar with the bed body 1. When the flip panel 3 deflects, the side panels 4 on the side of the flip panel 3 at the lower position will flip upward, thereby supporting the patient's body and preventing the patient's body from slipping off the flip panel 3 when the patient is in a sideways state. The support structure includes a guide rod 14 fixedly mounted on the bed 1 and a follower plate 13 slidably mounted on the guide rod 14 , and a first vertical groove 1301 is provided on the follower plate 13 ; A first protruding shaft 701 is fixed to a side of the slider 7 away from the abutting roller 8 , and the first protruding shaft 701 can slide in the first vertical groove 1301 ; The support structure further includes protrusions 15 arranged at both ends of the follower plate 13 and a reverse pulling kit connected to the side plates 4. The protrusions 15 cooperate with the reverse pulling kit to drive one group of the side plates 4 to deflect upward. Specifically, a vertical surface 1501 and a second horizontal surface 1502 are formed on the protrusions 15. The reverse pulling kit includes a traction plate 16 rotatably mounted on the bed body 1. A support rod 17 is rotatably mounted on the traction plate 16. One end of the support rod 17 away from the traction plate 16 is rotatably connected to the side plate 4. The reverse pulling kit further comprises a traction wheel 1601 rotatably mounted at an eccentric position of the traction disk 16 , and when the traction wheel 1601 cooperates with the vertical surface 1501 , the traction disk 16 can rotate.

[0040] In the initial state, the traction wheel 1601 is in contact with the vertical surfaces 1501 on the two protrusions 15 respectively. When the electric telescopic rod 10 drives the contact roller 8 to move along the length direction of the first horizontal plane 901 toward one of the first inclined surfaces 902, the follower plate 13 follows the movement of the contact roller 8 under the cooperation of the first vertical groove 1301 and the first convex shaft 701. At this time, the traction wheel 1601 on the front side of the movement direction of the contact roller 8 will be separated from the protrusion 15, and the traction wheel 1601 on the other side will abut against the vertical surface 1501 on the protrusion 15, thereby driving the traction disc 16 connected to the traction wheel 1601 to rotate, and at the same time, the side plate 4 away from the movement direction of the contact roller 8 is lifted upward by the support rod 17. In the process, the abutment roller 8 is always on the first horizontal plane 901, so that the flip plate 3 can maintain a horizontal state, that is, in this process, one and only the side plate 4 is pushed up, and with the movement of the follower plate 13, the traction wheel 1601 can abut against the second horizontal plane 1502, at this time, the side plate 4 can maintain a predetermined inclination angle and is in a locked state, and then the abutment roller 8 cooperates with the first inclined surface 902 to enable the flip plate 3 to drive the patient's limbs to tilt, that is, when the flip plate 3 moves, the side plate 4 on the low side of the flip plate 3 can perform an upward deflection action by utilizing the cooperation of the protrusion 15 and the traction wheel 1601, and a stop state can be formed for the patient, so as to prevent the patient from slipping off the flip plate 3 when the flip plate 3 drives the patient's limbs to tilt.

[0041] It is worth noting that when the flip plate 3 is deflected, the first protruding shaft 701 can make a circular motion at a certain angle. At this time, the first protruding shaft 701 can move along the length direction of the first vertical groove 1301, thereby preventing the occurrence of interference. At the same time, during this process, the follower plate 13 can also perform a lateral motion with a smaller displacement, but the traction wheel 1601 can always be in contact with the second horizontal plane 1502.

[0042] Through the above-mentioned arrangement, when the flip plate 3 drives the patient's limbs to tilt sideways, the side plate 4 on the lower side of the flip plate 3 can first perform an upward deflection action and reach a stop state to prevent the patient from slipping off the flip plate 3 when the flip plate 3 drives the patient's limbs to tilt sideways, thereby improving the stability of the patient in the process of assisting the patient to turn over.

[0043] See also Figure 2~Figure 3 , Figure 9~Figure 11 The anti-pressure sore auxiliary turning device also includes: a lifting member 18, a linear drive device 19 and a lifting assembly.

[0044] The lifting members 18 are provided in multiple groups and are slidably arranged in the retardation grooves 302 distributed along the length direction of the flip plate 3. Specifically, the lower end of the lifting member 18 is formed with an arc portion; The linear drive device 19 is installed on the flip plate 3, and a driving roller 23 is connected to the linear drive device 19. When the linear drive device 19 drives the driving roller 23 to move, the driving roller 23 can sequentially drive multiple groups of the lifting members 18 to move upward.

[0045] A stop groove is also provided on the side of the retardation groove 302 , and a stop shaft adapted to the stop groove is provided on the side of the lifting member 18 . When the stop shaft is in the stop groove, the upper surface of the lifting member 18 can be coplanar with the upper surface of the flip plate 3 .

[0046] Furthermore, when the linear drive device 19 is activated, it can drive the drive roller 23 connected thereto to make lateral movement, and when it abuts against the arc portion of the lower end of the lifting member 18, it can drive the lifting member 18 to move upward and act on the patient's back, which has a massage effect, can promote the patient's blood circulation, and reduce the occurrence of pressure sores.

[0047] Furthermore, after the lifting member 18 is lifted up, it can be reset under its own weight and the pressure of the patient's back.

[0048] The lifting assembly is connected to the linear drive device 19 and the driving roller 23. The lifting assembly can displace the driving roller 23 and the lifting member 18 when the driving roller 23 moves to the end of the stroke and moves in the opposite direction. The lifting assembly includes a transverse plate 20 detachably connected to the linear drive device 19, a fixed sleeve 21 is installed on the transverse plate 20, the interior of the fixed sleeve 21 is a hollow structure, and a telescopic plate 22 is slidably installed in the fixed sleeve 21, the telescopic plate 22 is rotatably connected to the driving roller 23, and a second convex shaft 24 that penetrates the fixed sleeve 21 is rotatably installed on the telescopic plate 22; The lifting assembly further includes a guide member 25 fixedly connected to the flip plate 3, wherein one end of the guide member 25 is provided with a second vertical groove 2501, and the other end is formed with a second inclined surface 2503, and the guide member 25 is provided with a second horizontal groove 2502 communicating with the second vertical groove 2501 along its length direction; A guide member 26 is rotatably mounted at the connection between the second inclined surface 2503 and the second vertical groove 2501; When the second convex shaft 24 rolls in the second transverse groove 2502 , the driving roller 23 and the lifting member 18 are misaligned.

[0049] In the initial state, the second cam 24 is in a state of being separated from the guide member 25, so that the driving roller 23 and the arc portion are in a state of being dislocated and separated. When the linear drive device 19 drives the transverse plate 20 to move, the driving roller 23 can move laterally under the drive of the fixed sleeve plate 21 and the telescopic plate 22. During this process, the second cam 24 can abut against the guide member 26, and the end of the guide member 26 away from its rotation center is in abutment with the lower side wall of the second transverse groove 2502, so that the guide member 26 has the effect of guiding the second cam 24, so that when the transverse plate 20 moves laterally, the second cam 24 can move along the second inclined surface 2503 until the second cam 24 moves to the upper surface of the guide member 25. During this process, the telescopic plate 22 can slide upward relative to the fixed sleeve plate 21, so that when the driving roller 23 moves, it can cooperate with the lifting member 18 one by one to drive The lifting member 18 is in motion to perform a massage action, and when the transverse plate 20 moves to the end of the stroke, the second cam 24 can enter the second transverse groove 2502 through the second vertical groove 2501 under the action of the gravity of the telescopic plate 22 and the driving roller 23. At this time, the telescopic plate 22 can slide downward relative to the fixed sleeve 21, so that the driving roller 23 and the arc portion are dislocated and separated again, and when the transverse plate 20 moves in the reverse direction, the driving roller 23 will not contact the arc portion, so that the lifting member 18 will not move when the driving roller 23 moves in the reverse direction, that is, when the driving roller 23 moves forward, it can drive the lifting member 18 to move in turn to perform a massage action, and when the driving roller 23 moves in the reverse direction, it can be dislocated and separated from the lifting member 18, so that the lifting member 18 remains stationary, thereby achieving the effect of directional expulsion of blood from the patient's back, further improving the blood flow of the patient's back, and preventing the occurrence of pressure sores.

[0050] It should be supplemented that, when the transverse plate 20 moves in the reverse direction to the end of the stroke, the second protruding shaft 24 can abut against the guide member 26, causing the guide member 26 to perform a deflection action, and after the guide member 26 is separated from the second protruding shaft 24, the guide member 26 can be reset, so that the transverse plate 20 moves again to repeat the upper process.

[0051] Through the above-mentioned arrangement, when the linear drive device 19 drives the driving roller 23 to move, the driving roller 23 can cooperate with the arc portion, and in turn drive multiple lifting members 18 to perform lifting actions, and act on the patient's back, which has a massage effect and can promote the patient's blood circulation. In addition, under the cooperation of the second cam 24 and the guide member 25 and the guide member 26, when the driving roller 23 moves in the opposite direction, it can be dislocated and separated from the arc portion, and the lifting member 18 can remain stationary, thereby achieving the effect of directional expulsion of blood from the patient's back, further improving the blood flow of the patient's back and preventing the occurrence of pressure sores.
