Description

Technical Field

[0001] This invention relates to the field of nursing equipment technology, and in particular to an anti-lateral lying splint. Background Technology

[0002] Open-heart surgery requires splitting the patient's sternum. After the surgery, in order to ensure healing, the patient must lie on their back for two months after the operation and cannot lie on their side, otherwise it is easy to cause malunion of the sternum. However, patients often unconsciously lie on their side while sleeping, so it is necessary to use a splint to prevent the patient from lying on their side.

[0003] Among the existing clamps used to prevent patients from lying on their side, some use straps to restrain the patient, that is, to directly bind the patient to the bed with straps to prevent the patient from turning over, while others use pressure plates, that is, to prevent the patient from turning over by fixing a pressure plate above the patient's body. However, when these existing clamps are used to restrain the patient, they all cause the patient to feel a great sense of restraint, and the patient's comfort is poor. Summary of the Invention

[0033] In use of this invention: Place the two clamping blocks 10 on both sides of the hospital bed. By rotating the clamping knob 5, the clamping blocks 10 can be clamped to the edge of the hospital bed. Then, adjust the height of the horizontal plate 8 by adjusting the telescopic plate 6, so that the horizontal plate 8 is at an appropriate height above the patient's body. Then, turn on the miniature air pump 3 and open the inflation valve 12 corresponding to the airbag 16 located above the patient's body. The miniature air pump 3 will then inflate the airbag 16, causing the airbag 16 to expand and press the soft pressure pad 7 onto the patient's body until the air pressure in the airbag 16 reaches the pressure relief valve 36. At this point, the soft pressure pad 7 is more comfortable on the patient's body. Then, close the inflation valve 12 and keep the miniature air pump 3 in the open state. At the same time, the piston block 60 is in the position of... Figure 3 In the middle position, rack 49 is in Figure 8 In the middle position, the pressure relief valve housing 37 is in the like Figure 7 With the intake valve housing 25 in the open position, the intake valve is in the following position. Figure 5 Closed state;

[0034] When the patient tries to turn over, their slightly turned body will compress the soft pressure pad 7, which in turn will compress the corresponding airbag 16. At this moment, the gas pressure in the airbag 16 will increase instantaneously. Since the pressure relief valve 36 has the same pressure as the initial pressure of the push spring 59, the instantaneous increase in air pressure will simultaneously push the pressure relief valve 36 to open and the piston block 60 to move. When the piston block 60 moves, it will push the longitudinal slide groove 57 to move through the push rod 58, which in turn will push the rack 49 to move along the straight section 53. The rack 49 will mesh with the gear 56 and drive the gear 56 to rotate. The gear 56 rotates When the device moves, it drives the intermediate shaft 29 to rotate, which in turn drives the first rotating block 40 to rotate. The pressure block 39 then moves away from the side of the first pressure rod 38. The elastic force of the first compression spring 41 drives the pressure relief valve block 42 to move into the pressure relief valve housing 37 and closes the pressure relief valve housing 37. At this time, the pressure relief valve 36 stops releasing pressure. If the patient continues to turn over, the increased air pressure in the airbag 16 will continue to compress the piston block 60, which in turn drives the gear 56 to rotate and drives the second rotating block 30 to rotate until the guide pressure block 28 compresses the second pressure rod 31. At this time, the second pressure rod 31 will compress the intake air. The valve block 34 opens the air intake valve housing 25, and the miniature air pump 3 inflates the airbag 16 through the air guide pipe 24 and the air intake pipe 22, thereby increasing the air pressure in the airbag 16 and preventing the patient from turning over. As the miniature air pump 3 continues to inflate the airbag 16 and continuously pushes the piston block 60, the rack 49 continues to slide along the straight section 53 until the slider 50 moves to the arc-shaped misalignment section 52. Guided by the arc-shaped misalignment section 52, the rack 49 moves to the top of the rebound section 54. At this time, the rack 49 and the gear 56 separate, and the gear 56 rebounds and rotates under the action of the coil spring 45. Then, the intake valve housing 25 will close, the micro air pump 3 will stop blowing air into the airbag 16, and at the same time, the pressure relief valve housing 37 will open, and the pressure relief valve 36 will depressurize the airbag 16 until the initial pressure. At this time, the piston block 60 will rebound due to the reduced pressure in the airbag 16, and the rack 49 will also rebound along the rebound section 54 until the slider 50 moves to the reset section 55. The elastic force of the compression spring 48 will push the rack 49 to move back to the straight section 53, thereby achieving the effect of preventing the patient from turning over. After preventing the patient from turning over, it can return to the initial state without causing pressure to the patient.
