Technical Field

Background technique

A turning bed is a medical device used to assist patients with limited mobility to turn over. During the treatment of burn patients, blisters may appear on the wound during the healing process.

When blisters appear on the patient's back, the patient cannot turn over on his own. At this time, medical staff are required to turn the patient over and treat the patient's injuries.

In the process of turning a patient over on an existing turning bed, the two ends of a bed board are first passed through the threaded rod through the rotating shaft and threaded rod arranged at the bedside, the threaded rod is compressed, and then the nut is turned onto the threaded rod to fix the upper bed board, and the patient and the bed board are fixed by a bandage, and then the rotating shaft on the lower bed board is loosened to turn the bed board over, and finally the lower bed board is removed to complete the turning of the patient. In this process, the staff needs to disassemble and install the nuts on the threads that lock the bed board for many times, and the two bed boards are fixed by only one straight rod, which may easily cause the lower bed board to shake during use.

Initially, the lower bed board 13 is located in the rotating disk 12, and the lower bed board 13 is hinged with two symmetrically distributed connecting plates 14, and the two symmetrically distributed connecting plates 14 are jointly hinged with the upper The bed board 15 and the symmetrically distributed rotating disks 12 are all slidably connected to the upper bed board 15. During use, the upper bed board 15 is placed in the rotating disk 12 to fix the rotating disk 12. The rotating disk 12 is slidably connected with two T-shaped blocks 2 symmetrically distributed up and down. The rotating disk 12 is threadedly connected with two symmetrically distributed threaded rods 21. The threaded rods 21 are threadedly matched with adjacent T-shaped blocks 2. When the threaded rods 21 are rotated, the threaded rods 21 enter the adjacent T-shaped blocks 2 to limit the adjacent T-shaped blocks 2. The rotating disk 12 is fixed with two symmetrically distributed limiting rods 2 2, the limit rod 22 is slidably connected with two first limit blocks 23 symmetrically distributed on the left and right, the thickness of the first limit block 23 gradually decreases from the adjacent T-shaped block 2 to the side away from the adjacent T-shaped block 2, the first limit block 23 is limited and slidably matched with the adjacent rotating disk 12, the first limit block 23 slides left and right in the adjacent rotating disk 12, the lower bed board 13 and the upper bed board 15 are both limited and matched with the two adjacent and symmetrically distributed first limit blocks 23, the lower bed board 13 and the upper bed board 15 are composed of a straight plate and four cylinders, two of which are located on the left side of the straight plate, and two cylinders are located on the left side of the straight plate. The column is located on the right side of the straight board. Taking the upper bed board 15 as an example, when the cylinder on the upper bed board 15 contacts the adjacent rotating disk 12, the adjacent first limit block 23 fixes the adjacent upper bed board 15 to prevent the upper bed board 15 from detaching. A first spring 24 is fixed between the two first limit blocks 23 symmetrically distributed on the same limit rod 22, and two first tension springs 25 symmetrically distributed are fixed between the T-shaped block 2 and the adjacent rotating disk 12. The first tension spring 25 is used to reset the adjacent T-shaped block 2, and the rotating tube 11 is provided with a rotating mechanism for driving its own rotation.

As shown in Figures 6 to 8, the rotating mechanism includes a sliding shaft 3, which is splined to the adjacent rotating tube 11. A rotating block 31 is fixedly connected to the side of the sliding shaft 3 away from the adjacent rotating tube 11. The rotating block 31 is used to drive the adjacent sliding shaft 3 to rotate. The rotating block 31 is fixedly connected to a symmetrically distributed handle 4, and the handle 4 is slidably connected to a sliding block 41. The rotating block 31 is slidably connected to two second limit blocks 42 symmetrically distributed front and back. A second spring 43 is fixedly connected between the second limit block 42 and the adjacent rotating block 31. The second spring 43 is used to extend the adjacent second limit block 42 out of the adjacent rotating block 31. A pull rope is fixedly connected between the sliding block 41 and the adjacent second limit block 42. The pull rope slides in the adjacent rotating block 31. When the sliding block 41 is pulled, the sliding block 41 drives the adjacent second limit block 42 through the pull rope to retract the adjacent second limit block 42 into the adjacent rotating block 31. The fixed frame 1 is fixedly connected to one side close to the adjacent rotating block 31 with two symmetrically distributed U-shaped blocks 44, a square hole is opened on the U-shaped block 44, and the U-shaped block 44 is limitedly matched with the adjacent second limit block 42 through the square hole. When the second limit block 42 corresponds to the square hole on the adjacent U-shaped block 44, the second limit block 42 protrudes to fix the adjacent rotating block 31, and the fixing frame 1 is slidably connected with two limit members 45 symmetrically distributed on the left and right, and two symmetrically distributed third springs 46 are fixedly connected between the two limit members 45 symmetrically distributed on the left and right and the fixing frame 1, and the third springs 46 Used to reset the adjacent limit member 45, the limit member 45 is squeezed and matched with the adjacent rotating block 31, and the rotating block 31 squeezes the adjacent limit member 45 in the process of approaching the adjacent U-shaped block 44. The limit member 45 is limited and matched with the lower bed board 13 or the upper bed board 15. Taking the left side limit member 45 as an example, in the process of the left side limit member 45 moving to the right, the limit member 45 gradually contacts with the lower bed board 13 or the upper bed board 15, thereby limiting the lower bed board 13 or the upper bed board 15.

As shown in Figures 5 and 6, the rotating tube 11 is sealed and slidably connected with the first sealing ring 5, the first sealing ring 5 is squeezed and matched with the adjacent sliding shaft 3, a fourth spring 51 is fixedly connected between the side of the first sealing ring 5 away from the adjacent sliding shaft 3 and the adjacent rotating tube 11, the fourth spring 51 is used to reset the adjacent first sealing ring 5, the side of the first sealing ring 5 close to the adjacent fourth spring 51 and the adjacent rotating tube 11 are filled with hydraulic oil, the rotating disk 12 is fixedly connected with a hydraulic shell 52, the hydraulic shell 52 is filled with hydraulic oil, and the hydraulic shell 52 is connected to the adjacent rotating tube 11 is connected, the hydraulic shell 52 is sealed and slidably connected with two symmetrically distributed first sliding rods 53, the first sliding rod 53 is limited and matched with the fixed frame 1, taking the first sealing ring 5 on the left side as an example, when the first sealing ring 5 on the left side moves to the right, the first sealing ring 5 squeezes the hydraulic oil to move into the adjacent hydraulic shell 52, and the hydraulic oil in the hydraulic shell 52 presses the first sliding rod 53 to enter the fixed frame 1, limiting the first sliding rod 53, and an unlocking component is arranged in the rotating disk 12, which is used to unlock the adjacent and symmetrically distributed first sliding rods 53.

As shown in FIG5 , the unlocking assembly includes four third limit blocks 6 distributed in a square shape. The four third limit blocks 6 distributed in a square shape are all slidably connected to the adjacent rotating disks 12. The lower bed board 13 and the upper bed board 15 are squeezed and matched with the adjacent third limit blocks 6. In the process of placing the upper bed board 15 or the lower bed board 13 into the rotating disk 12, the upper bed board 15 or the lower bed board 13 squeezes the adjacent third limit blocks 6. The third limit block 6 is fixedly connected with an L-shaped rod 61. The L-shaped rod 61 is limitedly matched with the adjacent first sliding rod 53. The first sliding rod 53 is provided with two upper and lower grooves. The lower groove of the first sliding rod 53 is limitedly matched with the L-shaped rod 61 adjacent to the upper side. The upper groove of the first sliding rod 53 is limitedly matched with the L-shaped rod 61 adjacent to the lower side. Initially, the lower L-shaped rod 61 is disengaged from the upper groove of the adjacent first sliding rod 53, and the upper L-shaped rod 61 enters the lower groove of the adjacent first sliding rod 53. A fifth spring 62 is fixedly connected between the L-shaped rod 61 and the adjacent rotating disk 12 , and the fifth spring 62 is used to reset the adjacent L-shaped rod 61 .

When using the device to turn a patient over, the medical staff first rotates the threaded rods 21 above the two rotating disks 12 to keep the threaded rods 21 above the rotating disks 12 disengaged from the upper T-shaped block 2, and then places the cylinder on the upper bed board 15 into the groove on the upper side of the rotating disk 12.

In the process of the cylinder on the upper bed board 15 entering the groove on the upper side of the rotating disk 12, taking the rotating disk 12 on the left side as an example, the upper bed board 15 squeezes the two first limit blocks 23 on the upper side, and the two first limit blocks 23 on the upper side move inward, and the first limit blocks 23 slide in the adjacent limit rods 22 and squeeze the first spring 24 between the two first limit blocks 23, and the first spring 24 contracts.

When the upper bed board 15 passes through the adjacent first limit block 23, the cylinder on the upper bed board 15 squeezes the two third limit blocks 6 on the upper side, and the third limit block 6 moves downward. During the movement of the third limit block 6 on the upper side, the adjacent L-shaped rod 61 is driven to move downward and squeeze the adjacent fifth spring 62, and the fifth spring 62 contracts. When the upper bed board 15 moves to as shown in Figure 5, the upper bed board 15 no longer moves. At the same time, the two first limit blocks 23 on the upper side are reset under the action of the adjacent first springs 24, and the upper bed board 15 is limited. Then the staff presses the T-shaped block 2 downward, and the T-shaped block 2 squeezes the two adjacent first limit blocks 23 downward. The first limit block 23 moves again into the slot of the rotating disk 12 to fix the first limit block 23. At the same time, the two first tension springs 25 on the upper side accumulate force. When the edge of the upper T-shaped block 2 is aligned with the edge of the rotating disk 12, the staff rotates the upper threaded rod 21 to fix the upper T-shaped block 2.

During the process of the upper L-shaped rod 61 descending, the lower side of the upper L-shaped rod 61 gradually slides out from the notch on the lower side of the adjacent first sliding rod 53 , thereby releasing the restriction on the first sliding rod 53 .

After fixing the upper T-shaped block 2, the staff fixes the patient. After fixation, the staff holds the two handles 4 on the left and right sides respectively. Taking the left rotating block 31 as an example, the staff holds the two left handles 4 and pulls the two adjacent sliding blocks 41 to move the sliding block 41 to the left. The sliding block 41 drives the adjacent second limit block 42 to move inward through the pull rope, and the second limit block 42 shrinks into the adjacent rotating block 31, disengaging the second limit block 42 from the adjacent U-shaped block 44, releasing the limit on the second limit block 42, and then the staff pulls the handle 4 to the left, and the handle 4 drives the adjacent sliding shaft 3 to move to the left through the adjacent rotating block 31. At the same time, the first sealing ring 5 is released under the pressure of the adjacent fourth spring 51, and the first sealing ring 5 moves to the left to absorb the hydraulic oil in the hydraulic shell 52, so that the two first sliding rods 53 move into the hydraulic shell 52 and gradually disengage from the fixing frame 1. When the fourth spring 51 is completely released, the first sliding rod 53 disengages from the fixing frame 1.

During the process of the left rotating block 31 moving to the left, the rotating block 31 gradually releases the adjacent limiting member 45, and the limiting member 45 moves to the left under the action of the elastic force of the two adjacent third springs 46, so that the limiting member 45 gradually disengages from the lower bed board 13. When the second limiting block 42 disengages from the adjacent U-shaped block 44, the limiting member 45 on the left disengages from the lower bed board 13.

After the second limit block 42 is disengaged from the adjacent U-shaped block 44, the medical staff rotates the rotating block 31, and the rotating block 31 drives the adjacent rotating tube 11 to rotate through the sliding shaft 3, and the rotating tube 11 drives the adjacent rotating disk 12 to rotate, and the rotating disk 12 drives the lower bed board 13 and the upper bed board 15 to rotate, thereby flipping the lower bed board 13 and the upper bed board 15.

After the flipping is completed, taking the left side as an example, the medical staff drives the handle 4 to move to the right, the handle 4 drives the rotating block 31 to move to the right, and the rotating block 31 drives the parts thereon to move to the right, so that the second limit block 42 gradually contacts the adjacent U-shaped block 44 and compresses the adjacent second spring 43. When the second limit block 42 is located in the square hole on the adjacent U-shaped block 44, the second limit block 42 is released under the action of the adjacent second spring 43, and the second limit block 42 is limited. By limiting the rotation of the adjacent rotating block 31 by the limiting of the second limit block 42, the rotating disk 12 is fixed, and the rotating disk 12 is quickly unlocked and fixed by pulling the sliding block 41, thereby reducing the patient's waiting time when turning over and quickly turning the patient over.

When the left rotating block 31 moves to the right, the rotating block 31 squeezes the adjacent first sealing ring 5 to the right through the adjacent sliding shaft 3, the fourth spring 51 on the left side contracts, and the first sealing ring 5 moves to the right to squeeze the hydraulic oil on its right side, so that the hydraulic oil enters the hydraulic shell 52 on the left side. The hydraulic shell 52 squeezes the two adjacent first sliding rods 53, so that the first sliding rods 53 enter the fixed frame 1, and the rotating disk 12 is fixed again to prevent the rotating disk 12 from rotating, causing the patient to fall and cause injury to the patient.

During the movement of the left rotating block 31 to the right, the rotating block 31 squeezes the left limit piece 45 to move to the right, and the limit piece 45 presses the two adjacent third springs 46, and the third springs 46 shrink. During the movement of the left limit piece 45 to the right, the limit piece 45 gradually enters the hole of the upper bed board 15, and the upper bed board 15 is accurately fixed again by the limit piece 45 to prevent the upper bed board 15 from shaking on the lower side after the rotation is completed.

After resetting the second limit block 42, the staff rotates the upper threaded rod 21 to release the upper T-shaped block 2 and lifts the lower bed board 13 upwards (the lower bed board 13 is above the upper bed board 15 at this time). The lower bed board 13 squeezes the adjacent first limit block 23 to disengage the lower bed board 13 from the rotating disk 12, completing the flipping.

During the process of the lower bed board 13 disengaging from the rotating disk 12, the upper L-shaped rod 61 rises under the action of the adjacent fifth spring 62, so that the upper L-shaped rod 61 enters the groove of the adjacent first sliding rod 53, thereby locking the adjacent first sliding rod 53. In the case where the lower bed board 13 and the upper bed board 15 are not placed in the rotating disk 12 at the same time, the rotating disk 12 cannot be unlocked even if the handle 4 is pulled, thereby improving safety during use.

After completing the wound treatment on the patient, repeat the above actions to reposition the patient.

The one-way valve in the second through hole 92 can only exhaust air from the second sliding rod 8 to the outside, the fixed rod 9 is fixedly connected with a sealing column 93 and a second sealing ring 94, a one-way valve is provided in the sealing column 93, and the one-way valve in the sealing column 93 can only intake air from top to bottom, and the sealing column 93 is fixedly connected with a third sealing ring 95, the third sealing ring 95 is sealed with the adjacent first through hole 91, and the second sealing ring 94 is sealed with the adjacent second through hole 92. When the fixed rod 9 is relative to the adjacent third When the second sliding rod 8 moves upward, the fixed rod 9 drives the adjacent second sealing ring 94 to move and block the adjacent second through hole 92. The fixed rod 9 drives the adjacent third sealing ring 95 to disengage from the adjacent first through hole 91 through the adjacent sealing column 93, and opens the first through hole 91. A sixth spring 96 is fixedly connected between the second sliding rod 8 and the adjacent sealing column 93. The sixth spring 96 is used to reset the adjacent sealing column 93. The side of the intake shell 72 away from the adjacent fixed block 82 is rotatably connected to the limiting ring 97. An annular groove and a straight groove are provided on the second sliding rod 8. The second sliding rod 8 is limited and cooperated with the adjacent limiting ring 97 through the annular groove and the straight groove. When the limiting ring 97 enters the annular groove on the adjacent second sliding rod 8, the second sliding rod 8 is limited, so that the adjacent fixed block 82 is fixed.

After the lower bed board 13 and the upper bed board 15 are fixed to the rotating disk 12, the staff starts the two air pressure pumps 7, and the air pressure pumps 7 respectively fill gas into the sealing airbag 71 on the lower bed board 13 and the cavity of the upper bed board 15. The sealing airbag 71 on the lower bed board 13 swells up, so that the sealing airbag 71 fits the human body to prevent the patient from sliding, and the gas in the cavity of the upper bed board 15 enters the sealing airbag 71 on the upper side through the two through holes on the air inlet shell 72.

Taking an air inlet shell 72 as an example, the gas enters between the air inlet shell 72 and the adjacent second sliding rod 8 from the upper through hole of the air inlet shell 72, and is then discharged into the adjacent sealed airbag 71. The gas gradually fills the upper sealed airbag 71 (the sealed airbag 71 fixed to the upper bed board 15). The upper sealed airbag 71 gradually increases in size and drives the adjacent fixed block 82 to move downward. The fixed block 82 drives the parts thereon to move downward. In the process of the fixed rod 9 moving downward, the fixed rod 9 gradually contacts the patient or the sealed airbag 71 below.

Taking an air intake shell 72 as an example, when the fixing rod 9 moves to contact the sealing airbag 71 below, the three circular airbags 81 are separated from the air intake shell 72. At this time, the fixing block 82 continues to move downward, and the fixing rod 9 moves upward relative to the adjacent fixing block 82 under the pressure of the sealing airbag 71 below. During the upward movement of the fixing rod 9, the sealing column 93 and the second sealing ring 94 are driven to move upward. The sealing column 93 drives the third sealing ring 95 to move upward and compresses the sixth spring 96. When the lower side of the fixing rod 9 contacts the fixing block 82, it stops. At this time The third sealing ring 95 is separated from the first through hole 91, and the second sealing ring 94 blocks the second through hole 92. At this time, the gas entering the air inlet shell 72 enters the second sliding rod 8 through the one-way valve in the first through hole 91, and the gas in the second sliding rod 8 enters the circular airbag 81 through the one-way valve and the second sealing ring 94 on the sealing column 93, and the circular airbag 81 is inflated. The circular airbag 81 is opened to fix the edge of the patient. When the two sealed airbags 71 wrap the patient, the staff turns off the air pressure pump 7 and turns the patient over.

In the above process, the circular airbag 81 opens around the edge of the patient. In the process of turning the patient over, the lower bed board 13 and the upper bed board 15 are gradually upright and then turned flat. When the lower bed board 13 and the upper bed board 15 are upright, the patient has a tendency to move downward. At this time, the patient squeezes the gap between the two sealed airbags 71 downward. Since the circular airbag 81 is opened at this time to wrap the edge of the patient, the patient squeezes the opened circular airbag 81, and the gas in the circular airbag 81 is squeezed, preventing the patient from slipping through the gap between the two sealed airbags 71.

When some parts of the patient are seriously injured, the squeezing force of the airbag may also cause damage to the patient. At this time, the limiting ring 97 corresponding to the part of the patient's wound is rotated. Initially, the limiting ring 97 slides in the straight groove of the adjacent second sliding rod 8. After the limiting ring 97 is rotated, the limiting ring 97 enters the annular groove on the adjacent second sliding rod 8, and limits the second sliding rod 8, so that the adjacent fixed block 82 is fixed. At this time, when the sealing airbag 71 wraps the patient, the sealing airbag 71 at the wound site cannot be completely released and the pressure is small, which further protects the patient and prevents the patient's wound from being injured.

When the patient's wound is cleaned and the patient is repositioned, the medical staff reversely turns on the air pressure pump 7, and the air pressure pump 7 evacuates the sealing airbag 71 to reset it. When the upper bed board 15 is taken out, the fixing rod 9 is no longer squeezed, and the fixing rod 9 is reset under the elastic force of the adjacent sixth spring 96. The sealing column 93, the adjacent second sealing ring 94 and the adjacent third sealing ring 95 are reset at the same time, and the gas in the circular airbag 81 is discharged through the one-way valve in the second through hole 92 to complete the reset.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
