Abstract
Description
Technical Field
[0001] This invention relates to the field of auxiliary structure technology for turning beds, specifically a multi-position safety protection device with zoned support suitable for turning beds. Background Technology
[0002] The turning bed used in clinical burn treatment consists of an upper bed and a lower bed, both of which can be turned over. The patient lies supine on the upper bed surface. Multiple sets of straps are installed on the upper and lower bed sides laterally, with each set of straps securing the ends of the upper and lower bed sides respectively. The multiple straps are evenly spaced along the length of the bed, completely sealing off the open space formed on both sides between the upper and lower bed. When the turning bed is in various support positions such as supine or tilted, the straps remain taut, forming a continuous flexible barrier. The system fills the gaps on the sides of the upper and lower beds, while the straps simultaneously restrict the patient's body laterally, limiting the displacement of the patient's torso and limbs in the gap between the upper and lower beds. Throughout the entire process of raising, tilting, and pre-turning the bed, the space on both sides of the upper and lower beds is continuously separated, preventing the patient's limbs and torso from sliding into the gap between the upper and lower beds. At the same time, multiple parallel straps form a lateral support surface, working together with the upper bed to maintain the patient's side-lying, semi-prone, and other zoned support postures, continuously isolating the hollowed-out areas on both sides of the upper and lower beds until the bed completes the overall turning action.
[0003] The existing turning beds are equipped with individual locking straps. Before turning the patient, nursing staff must unlock and untie each strap one by one. There are many straps along the length of the bed, and each strap is responsible for the patient's corresponding position. Untying all the straps requires unlocking all the buckles in sequence. The overall operation is complicated and takes a long time to untie each strap. Patients with large-area burns have fragile skin and poor tolerance. The time spent untying the straps before turning the patient directly prolongs the time the patient stays between the upper and lower beds, thus delaying the disassembly of the top bed. The patient's body is continuously suspended between the upper and lower beds, and the wound is continuously subjected to unbuffered traction and compression. The duration of wound compression and traction increases simultaneously. At the same time, the patient's various infusion and breathing tubes are continuously pulled by the body. The duration of tube traction and wound compression is extended as the straps are unlocked one by one. Summary of the Invention
[0004] To address the problems in the prior art, the present invention provides a multi-position safety protection device with zoned support suitable for turning beds.
[0005] The technical solution adopted by the present invention to solve its technical problem is: a multi-position safety protection device with zoned support suitable for turning over bed, including a restraint blanket, wherein a plurality of main straps are fixedly connected to one bottom end of the restraint blanket, and a plurality of secondary straps are fixedly connected to the other bottom end of the restraint blanket. Both the main strap and the adjacent secondary strap are equipped with a convenient positioning mechanism, which is used to automatically unlock the main strap and the secondary strap after use. The convenient positioning mechanism includes a support block and a positioning frame. A connecting groove is provided in the middle of the inside of the support block, a sliding groove is provided at the top of the inside of the support block, and a receiving groove is provided at the bottom of the support block. A movable frame is slidably connected in the sliding groove. A positioning block is fixedly connected to the bottom of the top wall of the movable frame. Symmetrically arranged abutment wheels are rotatably connected inside the positioning block. A counterweight is fixedly connected to the bottom of the movable frame. A water bladder is fixedly connected in the receiving groove. The water bladder is filled with a viscous fluid. Under the action of the viscous fluid, the deformation process of the water bladder will become mild.
[0006] Specifically, each of the secondary straps is symmetrical to the corresponding primary strap, the primary straps are all non-elastic, and the secondary straps are all elastic.
[0007] Specifically, the support block is fixedly connected to one end of the main strap, and the positioning frame is fixedly connected to one end of the secondary strap. Both the positioning frame and the support block are rigidly configured.
[0008] Specifically, the connecting groove and the sliding groove are in communication, the mobile frame is L-shaped, and the bottom end of the mobile frame slides through the connecting groove, the receiving groove, the water bag and is fixedly connected to the counterweight, the counterweight being spherical.
[0009] Specifically, the viscous fluid is made of dimethyl silicone oil. The viscous fluid has high damping and slow deformation characteristics, which inhibits the instantaneous deformation of the water bladder under pressure, preventing the water bladder from quickly completing deformation and contraction, and ensuring the overall structural stability of the counterweight block when the support block is tilted.
[0010] Specifically, the water bladder is adapted to the internal contour of the receiving groove, and the water bladder has flexible expansion and contraction properties. The water bladder can synchronously complete adaptive shape changes according to the confluence state of the viscous fluid inside.
[0011] The beneficial effects of this invention are: The fully automatic and convenient positioning mechanism consists of a support block, positioning frame, moving frame, positioning block, abutment wheel, counterweight, water bag and viscous fluid. After turning over, the main and auxiliary straps can be automatically unlocked, eliminating the need for medical staff to manually untie them one by one. This greatly shortens the operation time, reduces the time that burn patients spend stuck between the upper and lower beds, reduces the traction and compression of the wound, and also reduces the risk of various tubes being pulled and damaged. The water bladder is designed to match the contour of the receiving tank. The flexible material can adapt to the deformation of the internal viscous fluid. The dimethyl silicone oil viscous fluid has the ability to dampen deformation. During the tilting and rotation of the turning bed, the viscous fluid and the water bladder form an angle with the counterweight, thereby locking the position of the moving frame and the positioning block and preventing the positioning mechanism from being accidentally unlocked during the turning process. Only when the support block is completely flipped and inverted, the viscous fluid slowly flows into the receiving tank and the water bladder gradually contracts, allowing the counterweight to move down and drive the positioning block away from the positioning frame. This creates a sequence of tilting and locking, flipping into place, and then unlocking, ensuring stable protection throughout the entire turning process. The viscous fluid slows down the deformation speed of the water bladder, and the downward movement of the counterweight has a buffer delay, so unlocking is not completed instantly, allowing medical staff time to operate.

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0016] Please see Figures 1 to 7 The present invention provides the following technical solutions: Example 1: A multi-position safety protection device with zoned support suitable for a turning bed, including a restraint blanket 1, with multiple main straps 2 fixedly connected to the bottom of one side of the restraint blanket 1, and multiple secondary straps 3 fixedly connected to the bottom of the other side of the restraint blanket 1. The secondary straps 3 are all symmetrical to the corresponding main straps 2. The main straps 2 are all non-elastic, while the secondary straps 3 are all elastic. When in use, the restraint blanket 1 is positioned at the top of the upper bed frame, and the main restraint strap 2 and the secondary restraint strap 3 are wrapped around the lower bed frame respectively. Figure 1 Then, the secondary strap 3 is stretched to a certain extent. The elasticity of the secondary strap 3 can adapt to different distances between the upper and lower bed. Then, the secondary strap 3 is tied to the corresponding main strap 2. At this time, the main strap 2 and the secondary strap 3 seal the space on both sides of the bed. Each main strap 2 and secondary strap 3 corresponds to a different body position of the patient, preventing the patient from falling off the sides when the upper and lower bed are rotated.
[0017] Example 2: The technical solution that differs from Example 1 in this example includes: a convenient positioning mechanism 4 is provided on both the main strap 2 and the adjacent secondary strap 3. The convenient positioning mechanism 4 is used for automatic unlocking of the main strap 2 and the secondary strap 3 after use. The convenient positioning mechanism 4 includes a support block 41 and a positioning frame 42. A connecting groove 43 is provided in the middle of the inside of the support block 41, a sliding groove 44 is provided at the top of the inside of the support block 41, and a receiving groove 45 is provided at the bottom of the support block 41. A movable frame 46 is slidably connected in the sliding groove 44. A positioning block 47 is fixedly connected to the bottom of the top wall of the movable frame 46. Abutment wheels 48 are symmetrically arranged and rotatably connected inside the positioning block 47. A counterweight block 49 is fixedly connected to the bottom of the movable frame 46. A water bladder 50 is fixedly connected in the receiving groove 45. The water bladder 50 is filled with viscous fluid 51. Under the action of viscous fluid 51, the deformation process of the water bladder 50 will become mild. The support block 41 is fixedly connected to one end of the main strap 2, and the positioning frame 42 is fixedly connected to one end of the auxiliary strap 3. Both the positioning frame 42 and the support block 41 are rigidly set. The connecting groove 43 and the sliding groove 44 are in communication. The moving frame 46 is L-shaped. The bottom end of the moving frame 46 slides through the connecting groove 43, the receiving groove 45, the water bag 50 and the counterweight 49 and is fixedly connected. The counterweight 49 is spherical. The viscous fluid 51 is made of dimethyl silicone oil. The viscous fluid 51 has high damping and slow deformation characteristics, which prevents the water bag 50 from deforming instantly under pressure, so that the water bag 50 cannot quickly complete the deformation and contraction, ensuring the overall structural posture of the counterweight 49 is stable when the support block 41 is tilted. The water bag 50 is adapted to the internal contour of the receiving groove 45. The water bag 50 has flexible expansion and contraction performance. The water bag 50 can synchronously complete the adaptive shape change with the confluence state of the internal viscous fluid 51. In use, the counterweight 49 is moved upwards, compressing the water bladder 50 back into the receiving groove 45. The upward movement of the counterweight 49 causes the moving frame 46 to move upwards, which in turn causes the positioning block 47 to move upwards. At this point, the positioning block 47 retracts completely into the sliding groove 44 along with the top wall of the moving frame 46. Then, the secondary strap 3 can be stretched to a specified length, and the end of the secondary strap 3 connected to the positioning frame 42 is inserted into the connecting groove 43 on the support block 41. Afterwards, the counterweight 49 and the moving frame 46 are reset downwards, causing the moving frame 46 to reset the positioning block 47. The reset positioning block 47 is then inserted into the positioning frame 42, and the abutment wheel 4 on the positioning block 47... All 8 will abut against the inner wall of the positioning frame 42. At this time, the main strap 2 and the auxiliary strap 3 are connected. The connection of the other main straps 2 and auxiliary straps 3 is the same. At this time, the upper bed and the lower bed can be rotated counterclockwise. When the support block 41 rotates with the upper bed and the lower bed to an upward tilted state, if the operator makes the upper bed and the lower bed stay at this angle for a moment, the viscous fluid 51 in the water bag 50 will flow adaptively, causing one side of the water bag 50 to bulge. However, at this time, the water bag 50 is still located between the counterweight block 49 and the receiving groove 45. Because of the tilt, the water bag 50 cannot return to the receiving groove 45, and the counterweight block 49 cannot move downward due to gravity. Figure 7 This ensures that the counterweight 49 remains relatively stable during rotation, preventing accidental displacement of the counterweight 49 and thus preventing the main strap 2 and secondary strap 3 from accidentally unlocking. When the bed is rotated to the top, the patient has finished turning over, and the support block 41 is at the top and vertical. At this time, the viscous fluid 51 will flow back into the receiving groove 45, causing the water bag 50 to actively retract into the receiving groove 45. Simultaneously, the counterweight 49 will also actively move downwards, causing the water bag 50 to retract into the receiving groove 45. The displacement of the water bag 50 and the counterweight 49 takes several seconds, which provides a buffer for the staff. The counterweight 49 cannot move instantly; the downward movement of the counterweight 49... The moving frame 46 will move, which in turn will move the positioning block 47. When the positioning block 47 moves, the abutment wheel 48 will rotate due to its contact with the positioning frame 42. The rotation of the abutment wheel 48 allows the positioning block 47 to move smoothly with the moving frame 46. Then the positioning block 47 will separate from the positioning frame 42, and the end of the secondary strap 3 connected to the positioning frame 42 will exit from the support block 41, completing the automatic unlocking of the main strap 2 and the secondary strap 3. The operation is extremely convenient. After the patient is turned over, there is no need for staff to unlock the main strap 2 and the secondary strap 3 one by one, saving operation time and reducing the staff's energy consumption. Then the top bed can be disassembled for normal dressing changes for burn patients.
