Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a body positioning support device. Background Technology

[0002] In incubator environments, premature infants are typically placed in positioning support devices. A traditional positioning support device includes a base and a baffle assembly positioned above the base, allowing the premature infant to be placed on the base and surrounded by the baffle assembly. However, in this type of device, the base and baffle assembly are fixedly connected, and the relative positions of the components are not adjustable. Due to the premature infant's condition or body size, this positioning support device may not meet the actual needs, requiring additional pillows, fabrics, or other items to be placed under the premature infant's head or around the infant, making it less suitable for all situations.

When the second outer shell and / or the first surrounding plate is lowered, the positioning component cooperates with the selected length locking position to limit the relative position of the second outer shell and / or the first surrounding plate and the first rotating shaft in the first direction.

[0028] In use, the adjustable position of the second outer shell and / or the first enclosure allows the space defined by the positioning support device to accommodate premature infants of different lengths, improving its applicability. Furthermore, since the positioning support device can adapt to the infant's height in the first direction, the space between the device and the infant in that direction is controllable.

The angle locking assembly can lock the angle of the swing arm relative to the base.

[0030] The movable board supports the upper body of the premature infant and connects to the swing arm. Because the swing arm angle is adjustable, the movable board and swing arm adjust their angles relative to the base synchronously. An angle locking component locks the angle between the swing arm and the base, correspondingly locking the angle between the movable board and the base. This allows the movable board to be held at different angles, facilitating positional adjustment of the premature infant on the board. The movable board directly elevates the premature infant's upper body without requiring additional elevating structures. During operation, the movable board can be swung, causing the swing arm to move with it. This convenient operation allows for more intuitive judgment and quantification of the board's elevating effect, improving the accuracy of positional adjustment. It can be manually operated within the isolation room, increasing operational flexibility. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] The core of this utility model is to provide a body position support device that can adjust the angle and / or length with one hand in a limited space, making it more convenient and accurate to adjust and maintain body position. It can achieve independent lifting and flexion support of either half of the body, and can also be moved out of the limited space for easy maintenance.

[0054] The positioning support device provided by this utility model is applied to a premature infant incubator. It includes a base 1, and a second outer shell 14 and a first outer shell 13 arranged sequentially along a first direction. The first outer shell 13 is mounted on a movable plate 12. The angle of the movable plate 12 relative to the base 1 is adjustable; this adjustment is called angle adjustment. The distance between the second outer shell 14 and the first outer shell 13 in the first direction is also adjustable; this adjustment is called length adjustment. Alternatively, only one of the angle adjustment and length adjustment can be performed. Furthermore, a first rebound pad 21 can be provided on the second outer shell 14, and a second rebound pad 22 can be provided on the first outer shell 13. A side outer shell 15 can also be provided on the base 1. Of course, in other embodiments, the second outer shell 14 can be replaced by a first surrounding plate 24, or by a first surrounding plate 24 and a second outer shell 14, wherein the first surrounding plate 24 and the second outer shell 14 can be fixedly connected.

[0055] It should be noted that in the description of the embodiments of this application, the first direction, the second direction, and the third direction are three directions that are perpendicular to each other. In other embodiments, they may also be other included angles.

[0056] Please refer to Figures 1 to 8 Regarding the length adjustment portion, in a specific embodiment, the body positioning support device includes a base 1, which has a first direction and a second direction. The base 1 also includes a second outer shell 14, such as... Figure 5 As shown, the base 1 has multiple length locking positions 45 arranged sequentially along the first direction, the base 1 is provided with a first rotating shaft 23 extending along the second direction, and the second outer shell 14 is provided with a positioning component 4.

[0057] When the second housing 14 is raised, it can move on the base 1 to adjust the relative position of the second housing 14 and the first rotating shaft 23 in the first direction. When the second housing 14 is lowered, the positioning component 4 engages with the selected length locking position 45 to limit the relative position of the second housing 14 and the first rotating shaft 23 in the first direction. Specifically, when the second housing 14 is raised, at least a portion of its structure is further apart from the base 1 than when it is lowered.

[0058] In use, the second outer shell 14 and the first outer shell 13 are located at the head and tail ends of the infant, respectively. Based on the adjustable position of the second outer shell 14, the space defined by the positioning support device can accommodate premature infants of different lengths, making it suitable for infants of varying sizes and improving the applicability of the positioning support device. Furthermore, since the positioning support device can adapt to the infant's height in the first direction, the space between the positioning support device and the infant in that direction is controllable. Even if the infant is in a flexed position, the infant can remain in place and will not slide down relative to the slope where the infant's upper body is located.

[0059] Regarding the setting method of positioning component 4, such as Figure 5 As shown, the positioning component 4 includes a tension block 41 and a positioning part 412 for engaging with a length locking position 45. The positioning part 412 is connected to the tension block 41. The tension block 41 is fixed to the second housing 14 and slidably connected to the base 1. The second housing 14 can swing around the contact point between the tension block 41 and the base 1, thereby disengaging the positioning part 412 from the corresponding length locking position 45. At this time, by adjusting the rotation of the second housing 14 relative to the first rotating shaft 23 to lift it, the second housing 14 remains in the lifted state and moves against the base 1, thus adjusting the position of the second housing 14 in the first direction, which is convenient. In addition, after the second housing 14 moves into position in the first direction, the second housing 14 falls down. At this time, the positioning part 412 engages with the length locking position 45, thereby locking the position of the second housing 14 in the first direction.

[0060] Among them, such as Figure 5 As shown, the positioning part 412 is integrally fixed to the tension block 41 to ensure the connection strength between the two. Specifically, it protrudes in the second direction and is provided on one side of the tension block 41.

[0061] Among them, such as Figure 2 and Figure 5 As shown, the second outer shell 14 is fixedly connected to a connecting block 42, and a tension block 41 is connected to the connecting block 42. In addition, the tension block 41 and the connecting block 42, and the connecting block 42 and the second outer shell 14, can be connected by hexagonal prisms or other polygonal prisms to prevent rotation.

[0062] To facilitate the assembly and disassembly of the tension block 41 and the base 1, such as Figure 2 As shown, the positioning support device also includes a fixing plate 11 disposed on the base 1, which can be used to contact and support the infant, mainly supporting the lower body of the infant. A second outer shell 14 is disposed above the fixing plate 11, and a length locking position 45 is located between the fixing plate 11 and the base 1, and is shielded by the fixing plate 11. The fixing plate 11 is provided with a mounting groove 18 extending along a first direction. At least a portion of the structure of the second outer shell 14 or the positioning assembly 4, such as the tension block 41 and the positioning part 412, can enter or exit the mounting groove 18 through the opening 181 on the mounting groove 18, so that the second outer shell 14 is detachably connected to the base 1. In other embodiments, the mounting groove 18 may also be disposed on a side plate perpendicular to the fixing plate 11 and connected to the base 1.

[0063] For the length lock bit setting 45, such as Figure 5 As shown, the length locking position 45 includes a plurality of length positioning slots arranged sequentially along a first direction on the base 1. Correspondingly, the positioning part 412 is a positioning tooth provided on the stretching block 41. By moving the second housing 14 on the base 1, the positioning tooth can engage with the selected length positioning slot, thereby locking the distance between the first housing 13 and the second housing 14. Specifically, the second housing 14 can be manually moved to lock and unlock its position, thereby manually adjusting the distance between the movable plate 12 and the second housing 14, which is convenient to operate. In addition, as Figure 8 As shown, when at least a portion of the structure of the second housing 14 or the positioning component 4 is disassembled or assembled through the opening 181 on the mounting groove 18, the positioning part 412 falls from above into the length positioning groove corresponding to the opening 181, which can be considered as the second housing 14 or the positioning component 4 being successfully assembled.

[0064] Among them, such as Figure 5 As shown, the base 1 is fixedly connected to the travel block 44 at its end in the second direction. A length positioning groove is formed on the top surface of the travel block 44, specifically between adjacent ratchet teeth on the travel block 44. Additionally, the travel block 44 and the length positioning groove are located in the mounting groove 18, which protects the length positioning groove. Simultaneously, a slide rail 46 is provided on the travel block 44 on one side of the length locking position 45 in the second direction, allowing the tension block 41 to slide when the second housing 14 is raised, forming a contact point and fulcrum with the tension block 41.

[0065] The working principle of the length adjustment part in this embodiment includes: when it is necessary to adjust the position of the second outer shell 14 in the first direction, the second outer shell 14 is slightly lifted, the connecting block 42 is slightly lifted along with the second outer shell 14, the positioning part 412 can remain disengaged from each length locking position 45, the second outer shell 14 is translated while maintaining this state, the stretching block 41 can slide on the slide rail 46, after the adjustment is in place, the positioning part 412 is engaged in the corresponding length positioning groove, and the position of the second outer shell 14 in the first direction is locked.

[0066] Regarding the length adjustment portion, in one specific embodiment, the positioning component 4 can be configured in other ways. Please refer to [reference needed]. Figure 10 The positioning component 4 includes a tension block 41 and a positioning part 412 for engaging with a length locking position 45. The positioning part 412 is connected to the tension block 41. The tension block 41 is fixed to the second housing 14 and slidably connected to the base 1. The second housing 14 is able to swing around the contact point between the tension block 41 and the base 1, thereby disengaging the positioning part 412 from the corresponding length locking position 45.

[0067] The tension block 41 has an arc surface 411, and the fulcrum is located on the arc surface 411. Based on the arc surface 411, the contact point can smoothly switch on the arc surface 411 during the swinging of the second housing 14, which can improve the comfort of use.

[0068] Among them, in order to drive the positioning part 412 and the stretching block 41 to move, such as Figure 9 and Figure 10 As shown, the body positioning support device also includes a connecting rod 413 extending along the second direction. The positioning part 412 and the tension block 41 are arranged sequentially in the second direction and fixed to the connecting rod 413 respectively. At this time, the positioning part 412 and the tension block 41 are respectively assembled on the connecting rod 413, and the positional relationship between the positioning part 412 and the tension block 41 in the second direction can be set more freely.

[0069] The rotation centers of the arc surface 411 and the connecting rod 413 are arranged collinearly so that when the second housing 14 swings around the contact point, the connecting rod 413 rotates relative to the slider 43, which facilitates the adjustment of the angle of the second housing 14.

[0070] To improve the stability of the movement of the positioning part 412 and the tension block 41, such as... Figure 10 As shown, a guide rail 16 extending along the first direction is also fixedly mounted on the base 1. A slider 43 is slidably connected to the guide rail 16, and a connecting rod 413 is rotatably connected to the slider 43. At this time, when the second outer shell 14 is raised, that is, when the second outer shell 14 moves on the base 1, the slider 43 slides on the guide rail 16. Specifically, in the second direction, the guide rail 16 can be centrally located on the base 1. In the second direction, length locking positions 45 can be respectively provided on both sides of the guide rail 16 to ensure the locking effect.

[0071] In one specific embodiment, to facilitate the assembly and disassembly of the tension block 41 and the base 1, such as... Figure 1 and Figure 3As shown, the positioning support device also includes a fixing plate 11 disposed on the base 1, which can be used to contact and support the infant, mainly supporting the lower body of the infant. The second outer shell 14 is disposed above the fixing plate 11, and the length locking position 45 is located between the fixing plate 11 and the base 1, and is covered by the fixing plate 11. The fixing plate 11 is provided with a mounting groove 18 extending in a first direction. At least part of the structure of the second outer shell 14 or the positioning component 4 can enter or exit the mounting groove 18 through the opening 181 on the mounting groove 18, so that the second outer shell 14 can be detachably connected to the base 1. Specifically, the connecting block 42 is fixedly connected to the second outer shell 14, and the tension block 41 is located in the mounting groove 18. The connecting block 42 enters the mounting groove 18 through the opening 181 of the mounting groove 18 and is inserted into the tension block 41 to realize the assembly of the second outer shell 14.

[0072] Please refer to Figures 1 to 8 Regarding the angle adjustment, in a specific embodiment, the base 1 is provided with a first rotating shaft 23. The first rotating shaft 23 is located at the center of the base 1 in a first direction and extends along a second direction. The angle adjustment device 3 includes a rocker arm 32 and an angle locking assembly 31. The rocker arm 32 has two ends, and the second end 32b of the rocker arm 32 can rotate around a line parallel to the first rotating shaft 23. The angle locking assembly 31 can lock the angle of the rocker arm 32 relative to the base 1. During the rotation of the second end 32b of the rocker arm 32 around the line parallel to the first rotating shaft 23, the first end 32a of the rocker arm 32 moves closer to or further away from the first rotating shaft 23, and the angle locking assembly 31 can lock the first end 32a of the rocker arm 32.

[0073] The first end 32a of the swing rod 32 and the first rotating shaft 23 are used to rotatably connect the two ends of the movable plate 12, which supports the upper body of the premature infant. Since the angle of the swing rod 32 is adjustable, the movable plate 12 and the swing rod 32 synchronously adjust their angle with the base 1. The angle locking component 31 can lock the angle between the swing rod 32 and the base 1, correspondingly locking the angle between the movable plate 12 and the base 1. This allows the movable plate 12 to be maintained at different angles, facilitating the adjustment of the premature infant's position on the movable plate 12. The movable plate 12 can directly elevate the upper body of the premature infant without the need for additional elevating structures. During operation, the movable plate 12 can be swung, causing the swing rod 32 to move with it. This convenient operation allows for a more intuitive judgment and quantification of the elevating effect of the movable plate 12, improving the accuracy of position adjustment. Specifically, it can be manually operated in the isolation room, increasing operational flexibility.

[0074] Specifically, regarding the specific structure of the angle locking component 31, such as Figure 6 and Figure 7As shown, multiple angle locking positions 311, for example, three, are sequentially arranged along the first direction on the angle locking assembly 31. The first end 32a of the swing arm 32 is a free end. Under the action of external force, the swing arm 32 rotates parallel to the first pivot axis 23, and the first end 32a of the swing arm 32 slides on the angle locking assembly 31, so that the first end 32a of the swing arm 32 can be switched to be locked in different angle locking positions 311. The angle locking position 311 includes an angle positioning groove provided on the top surface of the angle locking assembly 31, and the first end 32a of the swing arm 32 is locked in the corresponding angle positioning groove by snap-fit. During the angle adjustment operation, when the first end 32a of the swing arm 32 moves to the corresponding angle positioning groove, it can fall into the angle positioning groove by its own gravity to achieve locking, and the locking is reliable.

[0075] Among them, for the angle positioning groove, such as Figure 6 As shown, the angle positioning groove is a ratchet groove that is inclined relative to the first direction. The inclination direction of the ratchet groove relative to the base 1 and the inclination direction of the swing rod 32 relative to the base 1 are the same. At this time, the ratchet groove and the swing rod 32 have a high degree of fit, which can support the swing rod 32 more stably and has a one-way locking and anti-disengagement effect.

[0076] It should be noted that, unless otherwise specified, in this application, the same tilt direction of the components relative to the base 1 refers to the same orientation of the acute angle formed with respect to the base 1, but does not limit the specific angle.

[0077] In this embodiment, the tilt direction of the swing arm 32 relative to the base 1 is the same as the tilt direction of the movable plate 12 relative to the base 1, so as to make full use of the space below the movable plate 12 and facilitate a compact structure. In other embodiments, such as Figure 13 As shown, the orientation of the acute angle formed by the movable plate 12 and the base 1, and the orientation of the acute angle formed by the swing rod 32 relative to the base 1 in the locked state can also be opposite.

[0078] To achieve the limiting of the lever 32, such as Figures 6 to 8 As shown, the angle adjustment device 3 also includes a guide block 33 fixed to the base 1. A rotary guide groove 331 is provided on the side of the guide block 33. The rotary guide groove 331 includes a rotary guide rail 3311, which divides the rotary guide groove 331 into an upper part, a lower part, and a transition part between the upper and lower parts. A guide rod 321 that is slidably inserted into the rotary guide groove 331 is fixedly provided on the side of the swing rod 32.

[0079] When the guide rod 321 is in the lower part of the rotary guide groove 331, the first end 32a of the swing rod 32 is locked in the selected angle locking position 311. When the guide rod 321 is in the upper part of the rotary guide groove 331, the first end 32a of the swing rod 32 can always disengage from each angle locking position 311. After the guide rod 321 enters the transition part from the lower part, it can enter the upper part in one direction.

[0080] By cooperating with the guide rod 321 and the rotary guide groove 331, the range of motion of the free end of the swing rod 32 can be constrained. Specifically, when the guide rod 321 is in the lower part of the rotary guide groove 331, as the movable plate 12 is continuously raised, the first end 32a of the swing rod 32 can slide unidirectionally with the swing rod 32 to lock at different angle locking positions 311. During this process, the guide rod 321 moves in the lower part of the rotary guide groove 331, specifically having space for movement in both the vertical direction and the linear direction away from the first rotating axis 23. When the movable plate 12 is raised to the highest lockable position, if it is necessary to reset to the lowest lowerable position, the movable plate 12 can be raised further, so that the guide rod 321 moves upward in the rotary guide groove 331, passes around the upper part of the rotary guide groove 331, and then reaches the lower part of the rotary guide groove 331, thereby causing the movable plate 12 to fall back to the lowest position.

[0081] During operation, due to the cooperation between the rotary guide groove 331 and the guide rod 321, the movable plate 12 can be reset to its lowest position by pulling it with one hand. Furthermore, the guide block 33 can be built into the body positioning support device, maintaining its aesthetic appearance and preventing damage to the device's shape or housing strength. Alternatively, in other embodiments without the guide block 33, rotary guide groove 331, and guide rod 321, the free end of the guide rod 321 may need to be exposed within the body positioning support device or connected to a structure exposed within the body positioning support device. Unlocking can be achieved by directly or indirectly controlling the position of the free end of the guide rod 321.

[0082] The movable plate 12 and the angle adjustment device 3 are connected to the module base plate 17, and the module base plate 17 is connected to the base 1. At this time, the movable plate 12, the angle adjustment device 3, and the module base plate 17 can be assembled and disassembled from the base 1 as a whole.

[0083] In this embodiment, the working principle of the angle adjustment of the movable plate 12 includes: manually raising the movable plate 12, causing it to rotate around the first rotating shaft 23, and the swing rod 32 naturally rotating around its connecting shaft with the movable plate 12 due to its own gravity. When the plate is raised to a suitable angle, the user releases the handle, and the free end of the swing rod 32 engages with the corresponding ratchet groove to complete the body position adjustment and support locking. Under the action of the swing rod 32's own gravity, the inclined ratchet groove and the swing rod 32 will not unlock, ensuring a secure one-way lock. When the movable plate 12 needs to be reset to its lowest position, it is further raised, causing the free end of the swing rod 32 to disengage from its ratchet groove. The guide rod 321 moves along the rotary guide groove 331, passing through the upper part of the rotary guide groove 331. During this process, the free end of the swing rod 32 is higher than the locking block and is not obstructed by the locking block 31. The movable plate 12 is then lowered, and the swing rod 32 returns to its original position, thus resetting the movable plate 12.

[0084] Regarding the specific method of angle adjustment, in one specific embodiment, such as Figures 9 to 12 As shown, the angle locking assembly 31 includes a power input component 312 and a transmission structure connecting the power input component 312 and the first end 32a of the rocker arm 32. Under the action of external force, the power input component 312 can drive the rocker arm 32 to rotate around the first rotating shaft 23 in parallel with the first rotating shaft 23 through the transmission structure, and the first end 32a can move closer to or further away from the first rotating shaft 23. After the external force is released, the transmission structure or the power input component 312 can lock the rocker arm 32. Due to the addition of the power input component 312 and the transmission structure, the power input component 312 can be directly controlled to drive the rocker arm 32 to move, thereby driving the movable plate 12 to adjust the angle, which can maintain the accuracy of the angle adjustment.

[0085] The external force received by the power input component 312 can be a manually applied external force or an external force input by a power device such as a motor.

[0086] The transmission structure includes a gear assembly 314 and a lead screw and nut assembly 313. The lead screw and nut assembly 313 includes a lead screw 3131 and a movable nut 3132 connected to the lead screw 3131. The first end 32a of the rocker arm 32 is connected to the movable nut 3132 through the gear assembly 314.

[0087] During the angle adjustment process, the power input component 312, under the action of external force, can drive the lead screw 3131 to rotate through the gear assembly 314, so that the moving nut 3132 drives the first end 32a of the rocker arm 32 to approach or move away from the first rotating shaft 23 and the rocker arm 32 rotates around the parallel line of the first rotating shaft 23. After the external force is released, the lead screw 3131 and the moving nut 3132 can be locked relative to each other.

[0088] In order to facilitate the input of external force to the power input component 312, at least a portion of the structure of the power input component 312 is externally located on at least one side of the body positioning support device along the first direction, specifically a knob that is completely externally located on the body positioning support device.

[0089] Regarding the specific method of angle adjustment, in one specific embodiment, such as Figures 14 to 15 As shown, the movable plate 12 is fixedly connected to the second end 32b of the swing arm 32, and the angle locking assembly 31 is a ratchet mechanism used to lock the first end 32a of the swing arm 32. Specifically, the first end 32a of the swing arm 32 can be directly rotatably connected to the first rotating shaft 23.

[0090] Among them, such as Figures 14 to 15 As shown, the ratchet mechanism includes an elastic pawl assembly 35 and a toothed surface 34 on the rocker arm 32. During the process of the rocker arm 32 swinging around the first pivot 23 in a preset direction, the toothed surface 34 can overcome the elastic force to push the elastic pawl assembly 35, so as to switch the tooth grooves on the toothed surface 34 that mesh with the elastic pawl assembly 35, so that the rocker arm 32 can be maintained at different angles.

[0091] Specifically, the elastic pawl assembly 35 includes a pawl 351 rotatably connected to the base 1 and an elastic element 352 connected between the pawl 351 and the base 1. The pawl 351 is used to engage with the tooth groove of the tooth surface 34. The elastic element 352 and the pawl 351 provide elasticity and engagement respectively, and the pawl 351 does not need to be elastic, which can ensure the locking strength between it and the rocker arm 32.

[0092] Additionally, the angle locking assembly 31 also includes a fixing plate 36 rotatably connected to the first rotating shaft 23. A first pawl locking protrusion 361 and a second pawl locking protrusion 364 are sequentially fixed along the circumferential direction on the circumferential surface of the fixing plate 36, forming a pawl groove 362 between them. The toothed surface 34 is along a preset direction (…). Figure 15 After passing the elastic pawl assembly 35 in a clockwise direction, the rocker arm 32 can press the first pawl locking protrusion 361 in a preset direction to drive the fixed plate 36 to rotate, and the second pawl locking protrusion 364 presses the elastic pawl assembly 35 to rotate until the elastic pawl assembly 35 is engaged in the pawl slot 362. At the same time, the elastic pawl assembly 35 disengages from the tooth surface 34 in the radial direction of the first rotating shaft 23. At this time, since the elastic pawl assembly 35 is locked by the fixed plate 36, the rocker arm 32 is not constrained by the elastic pawl assembly 35 and can rotate to reset.

[0093] The fixed plate 36 also has a pawl unlocking protrusion 363 fixedly provided on its peripheral surface. After the elastic pawl assembly 35 engages with the pawl slot 362, the swing arm 32 can move in the opposite direction to the preset direction. Figure 15The rocker arm moves counterclockwise and the pawl unlocking protrusion 363 is pressed to drive the fixing plate 36 to rotate, thereby releasing the fixing plate 36 from the pawl slot 362. Then the elastic pawl assembly 35 is reset. At this time, when the rocker arm 32 moves along the preset direction again, the different tooth grooves on the tooth surface 34 of the rocker arm 32 can engage with the elastic pawl assembly 35 in sequence, and the next round of angle adjustment can be repeated.

[0094] Specifically, depending on actual needs, when the second end 32b of the swing rod 32 rotates around the first rotating shaft 23 or a line parallel to the first rotating shaft 23, it can drive the movable plate 12 to swing around the first rotating shaft 23. In this case, the swing rod 32 is the driving member, and the movable plate 12 is the driven member. And / or, when the movable plate 12 swings around the first rotating shaft 23, it can drive the second end 32b of the swing rod 32 to rotate around the first rotating shaft 23 or a line parallel to the first rotating shaft 23. In this case, the movable plate 12 is the driving member, and the swing rod 32 is the driven member.
