Description

Technical Field

[0001] This invention relates to the field of assistive stents, specifically to a medical cardiovascular nursing turning assistive stent. Background Technology

[0002] Cardiovascular nursing refers to nursing measures for cardiovascular diseases. Cardiovascular diseases are among the leading causes of death in humans. Bedridden patients are unable to turn over on their own due to physical weakness or disease limitations. Staying in the same position for a long time can easily lead to complications such as bedsores and hypostatic pneumonia. It is necessary to turn patients frequently to reduce pressure on local tissues, prevent the occurrence of complications, and adapt to the needs of treatment and nursing.

[0003] In some cases, patients are turned over manually by medical staff. Due to the patient's own limitations, turning over is cumbersome and increases the workload of medical staff. In addition, some auxiliary turning devices can only turn the patient in the same direction. Therefore, it is necessary to propose a medical cardiovascular nursing turning assistance stent. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a medical cardiovascular nursing turning assistance stent.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a medical cardiovascular nursing turning assistance support, including a base, a tilting mechanism, a tilting drive mechanism, a lifting mechanism, and a lifting drive mechanism. The upper end of the base is provided with a tilting mechanism, the lower end of the tilting mechanism is provided with a tilting drive mechanism, the inside of the tilting mechanism is provided with a lifting mechanism, and the lower part of the lifting mechanism is provided with a lifting drive mechanism. A groove is provided through the upper surface of the base, and a support block is fixedly connected symmetrically to the lower surface of the base.

[0006] Specifically, the tilting mechanism includes a first bed board, and two first bed boards are provided at the upper end of the base. The two first bed boards are connected by hinges. Limiting grooves are formed through the inner walls of the two ends of the groove relative to the position of the first bed board. Limiting blocks are slidably connected to the inner walls of several limiting grooves. Limiting holes are formed through the outer walls of the two first bed boards relative to the position of the limiting blocks. One end of each of the two limiting blocks extends into the corresponding limiting hole.

[0007] Specifically, the tilting drive mechanism includes a push wheel, a drive rod rotatably connected to the inner walls of one end of the two support blocks, a push wheel rotatably connected to the outer wall of the drive rod, a moving groove penetrating through the inside of the push wheel at the position of the drive rod, a moving block slidably connected to the inner wall of the moving groove, and one end of the moving block extending through into the drive rod, a first screw hole penetrating through the inner wall of one end of the moving groove, and one end of the first screw hole extending through to the outside of the push wheel and threadedly connected to a first fixing screw, and one end of the first fixing screw extending to the outside of the push wheel and having a handle.

[0008] Specifically, the lifting mechanism includes a second bed plate. The upper surfaces of the two first bed plates, away from the push wheel, are each provided with a hole and rotatably connected to a second bed plate. One of the outer walls of the support block is fixedly connected to a rotating seat relative to the position of the second bed plate. The upper surfaces of the two rotating seats are rotatably connected to internally threaded tubes. The inner walls of the two internally threaded tubes are threaded with threaded rods. One end of each of the two threaded rods extends outside the internally threaded tube and is fixedly connected to a top block. The lower surfaces of the two second bed plates are fixedly connected to trapezoidal blocks relative to the position of the top blocks. The lower surfaces of the two trapezoidal blocks are provided with grooves, and one end of each of the two top blocks extends into the grooves.

[0009] Specifically, the lifting drive mechanism includes mounting blocks. One of the support blocks has a mounting block fixedly connected to one side of its outer wall, which is located on the side of the rotating seat. Both mounting blocks have holes through their outer walls at one end and are rotatably connected to rotating rods. The outer walls of the two internally threaded tubes are fixedly fitted with first bevel gears relative to the rotating rods. Both ends of the two rotating rods are fixedly connected with second bevel gears, and two of the second bevel gears mesh with the first bevel gears on the same side. The drive rod has a groove through its outer wall on one side of the mounting block and is slidably connected to a slide tube. The outer wall of the slide tube is fixedly fitted with a third bevel gear, and the other two second bevel gears mesh with the third bevel gear.

[0010] Specifically, a first spring is fixedly connected to the outer wall of one end of the limiting block located in the limiting groove, and the other ends of the two first springs are fixedly connected to the base. A second spring is fixedly connected to the outer wall of one end of the moving block located in the moving groove, and the other end of the second spring is fixedly connected to the push wheel.

One end of the second fixing screw extends out of the second screw hole and is provided with a handle.

[0013] The beneficial effects of this invention are: (1) The cardiovascular nursing turning support of the present invention has the patient lying on the first bed board. When the patient needs to turn over, the drive motor is started to drive the drive rod and the push wheel to rotate. The push wheel pushes the first bed board to rotate outward. The first bed board pushes the patient to turn over. The drive motor can be started to drive the drive rod and the push wheel to rotate in the opposite direction, so that the patient can turn over in the opposite direction. After the turning is completed, the first bed board moves back into the base. The first spring pushes the limiting block to move into the limiting hole to limit and fix the first bed board. The patient can be turned left and right, which increases the flexibility of the device.

[0014] (2) The cardiovascular nursing turning support described in this invention has a sliding tube. The sliding tube drives the third bevel gear to abut against the second bevel gear. The drive motor is started to drive the drive rod and the third bevel gear to rotate. The third bevel gear drives the second bevel gear, the first bevel gear and the internal threaded tube to rotate. The internal threaded tube drives the threaded rod and the top block to move upward. The top block pushes the second bed board to rotate. The second bed board pushes the patient to get up. It can assist the patient to get up without other devices, reducing the workload of medical staff and increasing the flexibility of the device. Attached Figure Description

[0019] like Figures 1-7 As shown, the present invention provides a medical cardiovascular nursing turning support, comprising a base 1, a tilting mechanism 2, a tilting drive mechanism 3, a lifting mechanism 4, and a lifting drive mechanism 5.

[0021] The tilting drive mechanism 3 includes a push wheel 31. The inner walls of two support blocks 6 are rotatably connected to a drive rod 32. The outer wall of the drive rod 32 is rotatably connected to the push wheel 31. The push wheel 31 has a moving groove 33 through it located at the position of the drive rod 32. The inner wall of the moving groove 33 is slidably connected to a moving block 34. One end of the moving block 34 extends through into the drive rod 32. The inner wall of one end of the moving groove 33 has a first screw hole 35 through it. One end of the first screw hole 35 extends through into the outside of the push wheel 31 and is threadedly connected to a first fixing screw 36. One end of the first fixing screw 36 extends into the outside of the push wheel 31 and is provided with a handle.

[0022] The lifting mechanism 4 includes a second bed plate 41. The upper surfaces of the two first bed plates 21, away from the push wheel 31, are each provided with a hole and are rotatably connected to the second bed plate 41. One side of the outer wall of one of the support blocks 6 is fixedly connected to a rotating seat 42 relative to the position of the second bed plate 41. The upper surfaces of the two rotating seats 42 are rotatably connected to internally threaded tubes 43. The inner walls of the two internally threaded tubes 43 are each threaded with threaded rods 44. One end of each of the two threaded rods 44 extends out of the internally threaded tubes 43 and is fixedly connected to a top block 45. The lower surfaces of the two second bed plates 41 are fixedly connected to trapezoidal blocks 46 relative to the position of the top blocks 45. The lower surfaces of the two trapezoidal blocks 46 are provided with grooves, and one end of each of the two top blocks 45 extends into the grooves.

[0023] The lifting drive mechanism 5 includes mounting blocks 51. One of the support blocks 6 has a mounting block 51 fixedly connected to one side of the outer wall of the rotating seat 42. The outer walls of both mounting blocks 51 have holes through them and are rotatably connected to rotating rods 52. The outer walls of the two internally threaded tubes 43 are fixedly fitted with first bevel gears 53 relative to the position of the rotating rods 52. The two ends of the two rotating rods 52 are fixedly connected with second bevel gears 54, and the two second bevel gears 54 mesh with the first bevel gears 53 on the same side. The drive rod 32 has a groove through it on the outer wall of one side of the mounting block 51 and is slidably connected to a slide tube 55. The outer wall of the slide tube 55 is fixedly fitted with a third bevel gear 56, and the other two second bevel gears 54 mesh with the third bevel gear 56.

[0024] Among them, the outer wall of one end of the limiting block 23 located in the limiting groove 22 is fixedly connected with a first spring 7, and the other end of the two first springs 7 is fixedly connected to the base 1. The outer wall of one end of the moving block 34 located in the moving groove 33 is fixedly connected with a second spring 8, and the other end of the second spring 8 is fixedly connected to the push wheel 31.

[0025] One of the support blocks 6 has a drive motor 9 fixedly connected to one side of its outer wall relative to the drive rod 32 via a mounting bracket. One end of the drive rod 32 extends through a bearing to the outside of the support block 6 and is fixedly connected to the drive motor 9 via a coupling.

[0026] The outer wall of the drive rod 32 has two second screw holes 10 that are equidistant from the slide tube 55. One end of one of the second screw holes 10 extends through the slide tube 55 and is threadedly connected to a second fixing screw 11. One end of the second fixing screw 11 extends through the second screw hole 10 and is provided with a handle.

[0027] In use, the drive motor 9 is connected to an external power supply via a controller. When the patient is lying on the first bed board 21 and assisted turning is required, the handle is first used to move the second fixing screw 11 out of the second screw hole 10, moving the slide tube 55 to one side. The slide tube 55 causes the third bevel gear 56 to separate from the second bevel gear 54. Then, the second fixing screw 11 is rotated into the second screw hole 10 to limit the slide tube 55. The drive motor 9 is then started, causing the drive rod 32 and the push wheel 31 to rotate. The push wheel 31 then rotates the first bed board 21. When turning the patient over the first bed board 21, the drive motor 9 can rotate the push wheel 31 in the opposite direction to adjust the rotation direction of the first bed board 21 and the patient. When the first bed board 21 is set in a parallel state, the first spring 7 pushes the limiting block 23 to move into the limiting groove 22 to limit and fix the first bed board 21. When the patient needs to turn over, the handle drives the first fixing screw 36 to rotate from the first screw hole 35 to the outside, so that the first fixing screw 36 is separated from the moving block 34. Then, the handle is used to open the second fixing screw... Rod 11 moves out of the second screw hole 10. The slide tube 55 drives the third bevel gear 56 to engage with the second bevel gear 54. The drive motor 9 is started, causing the drive rod 32 to rotate. The push wheel 31 pushes the moving block 34 into the moving groove 33 and compresses the second spring 8. The drive rod 32 drives the slide tube 55 and the third bevel gear 56 to rotate. The third bevel gear 56 drives the meshing second bevel gear 54 and the first bevel gear 53 to rotate. The first bevel gear 53 drives the internally threaded tube 43 to rotate, which in turn drives the threaded rod 44 and the top block 45 through the internally threaded tube 43. Moving upwards, the top block 45 drives the trapezoidal block 46 and the second bed board 41 to rotate outwards, causing the second bed board 41 to push the person to stand up. When it is not necessary to stand up, the drive motor 9 is started to drive the drive rod 32 to rotate in the opposite direction, and the third bevel gear 56 is separated from the second bevel gear 54. The drive rod 32 rotates to the side of the moving block 34, and the second spring 8 pushes the moving block 34 to move into the drive rod 32, limiting the drive rod 32. Then, the handle drives the first fixing screw 36 to move into the moving groove 33, limiting and fixing the drive rod 32 and the push wheel 31.
