Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a patient transfer and mobility assistance device for critical care. Background Art

[0002] Patients in critical care generally lose their ability to move temporarily. In order to fully understand the patient's condition, various examinations are often required. Therefore, patients need to be transferred between different departments within the hospital, such as from the emergency room to the intensive care unit (ICU), or from the operating room to the ward, or from the ward to the examination department.

[0003] In particular, when transferring to the examination department for specific examination items, the patient must be moved to the designated examination bed. In the past, the patient could only be lifted onto the examination bed by multiple people, which was time-consuming and labor-intensive, and easily caused secondary injuries to the patient. At present, a transfer bed has appeared in the prior art, such as a transfer bed for critically ill patients disclosed in the Chinese patent with authorization announcement number CN219184579U, which includes a bed frame, a bed board and a transfer platform. The bed board is horizontally arranged on the top of the bed frame, and the transfer platform is movably mounted on the bed board. A lifting platform, a support shaft, a control drive mechanism and an operation screen are provided on the bed board. The control drive mechanism is arranged inside the bed board and controls the support shaft to perform lifting and lowering movements. The lifting platform can be lifted and lowered on the bed board through the support shaft. The operation screen is arranged at one end of the bed board and is electrically connected to the control drive mechanism. The control drive mechanism is issued instructions through the operation screen to control the lifting height of the support shaft; the lifting platform is provided with parallel slide rails in the left and right directions, and the bottom surface of the transfer platform is provided with a slide groove, and the transfer platform can be detachably mounted on the lifting platform by sliding left and right. The utility model provides a transfer bed which is applied to critically ill patients, does not change the patient's body position, stably moves the patient, avoids causing secondary injury to the patient, reduces the workload of medical staff, and improves the efficiency of patient transfer.

[0004] Although the above disclosed transfer bed can solve the problem of not needing multiple people to lift the patient, when such a transfer bed is used to move the patient, if there is only one family member or medical staff to assist, the patient cannot be protected or assisted in real time. For example, when the patient is wearing a treatment device and needs to be manually fixed, the family members and medical staff need to keep close to the patient. In this case, when the patient is completely moved from the transfer bed to the examination bed, the family members or medical staff need to push the transfer bed away or go around to the other side of the examination bed before they can manually protect or assist the patient again. This is not only troublesome, but also there is a period of separation from the patient, which is prone to accidents. . Summary of the invention

When the transfer plate 3 moves, the connecting frame 7 undergoes mechanical movement synchronously.

[0021] A connecting slide 41 is provided at the end of the movable board 4, and the connecting slide 41 passes through the movable board 4. A connecting rod 42 with a sliding connection is provided inside the bed board 2. The connecting rod 42 moves into the connecting slide 41 to connect the connecting rod 42 to the bed board 2.

[0022] Specifically, after the movable board 4 and the bed board 2 are spliced ​​together and located in the same horizontal plane, the handle 43 is used to control the movement of the connecting rod 42, and the connecting rod 42 is inserted into the connecting slide 41 to fix the movable board 4 and the bed board 2. If only one end is fixed, the movable board 4 is inclined. If both ends of the movable board 4 are fixed, the movable board 4 and the bed board 2 are spliced ​​to form a transfer bed. If both ends of the movable board 4 are not fixed, the movable board 4 can be directly removed. When the movable board 4 is converted from a horizontal state to a vertical state, a passage 5 will be formed between the two bed boards 2 for medical staff or family members to pass through, and several movable boards 4 can be selected to be removed according to the body shape of the medical staff to meet different usage requirements.

[0023] An inner cavity 45 is provided inside the movable plate 4, and the inner cavity 45 penetrates the movable plate 4. The support bars 6 are rotatably arranged inside the inner cavity 45 via a connecting shaft. Several of the support bars 6 are connected to a driving member 46, and the driving member 46 is connected to the connecting rod 42. When the connecting rod 42 moves, the support bars 6 are controlled to rotate through the driving member 46.

[0024] Specifically, after the movable board 4 and the bed board 2 are spliced ​​to form a transfer bed, the support bar 6 that is completely in the inner cavity 45 of a certain movable board 4 can be rotated so that its two ends are respectively located in the inner cavities 45 of two adjacent movable boards 4, that is, the support bar 6 is placed between the two movable boards 4 to increase the load-bearing capacity of the splicing and maintain stability; and when the support bar 6 is completely stored in the inner cavity 45 of a certain movable board 4, several support bars 6 are distributed in a fishbone shape, thereby achieving the purpose of achieving the same load-bearing effect and stability at various locations of the movable board 4.

[0025] The driving member 46 includes an adjusting unit and a transmission unit, wherein the adjusting unit is used to control the rotation of the support bar 6, and the transmission unit is used to provide power for the adjusting unit. Transmission units are respectively provided at both ends of the movable plate 4, and the transmission units at both ends provide power for the adjusting unit; the adjusting unit includes a bidirectional screw rod 461, the outer wall of the bidirectional screw rod 461 is sleeved with a connecting disk 462, the inner wall of the connecting disk 462 is provided with a screw nut matching the bidirectional screw rod 461, and when the bidirectional screw rod 461 rotates, the connecting disk 462 is driven to move, and the outer wall of the support bar 6 is connected to a hinged connecting rod 46 3, and the other end of the connecting rod 463 is hinged to the connecting plate 462; the transmission unit includes a gear 464 and a rack 465, the gear 464 is sleeved on the end of the bidirectional screw rod 461, the rack 465 is meshed with the gear 464, the outer wall of the rack 465 is provided with a pushing block 466, the pushing block 466 extends into the connecting slide 41, the outer wall of the pushing block 466 is provided with a groove 467, the outer wall of the connecting rod 42 is provided with a protrusion 468 matching the groove 467, and the protrusion 468 and the groove 467 are embedded and connected through a self-locking component.

[0026] In a preferred embodiment, according to the number of movable plates 4, a corresponding number of protrusions 468 are set on the outer wall of the connecting rod 42, but in order to achieve mechanical movement, multiple protrusions 468 are staggered to ensure that the connecting rod 42 can be smoothly inserted into multiple connecting slides 41.

[0027] Specifically, when the connecting rod 42 is inserted and moved into the connecting slide 41, the protrusion 468 on the outer wall of the connecting rod 42 is engaged with the groove 467, which will drive the pushing block 466 to move. At this time, the pushing block 466 will drive the rack 465 to move synchronously, so that the gear 464 will rotate, and the gear 464 will drive the two-way screw rod 461 to rotate. Since the threads on both sides of the two-way screw rod 461 are opposite, and the support bars 6 on both sides are symmetrically arranged, when the two-way screw rod 461 rotates and drives the connecting plate 462 to move through the nut, the connecting plate 462 will pull one end of the support bar 6 to move through the connecting rod 463, so that the angle of the support bar 6 changes, and the transmission units arranged at both ends of the two-way screw rod 461 have the same control method, and will also drive the support bar 6 to undergo the same mechanical movement, and are divided into two groups for ease of use.

[0028] The self-locking assembly includes an inclined block 4691 and a top block 4692. The inner wall of the push block 466 is provided with a movable groove 1. The inclined block 4691 is slidably arranged in the movable groove 1. One end of the inclined block 4691 extends into the groove 467. The outer wall of the protrusion 468 is provided with a limit opening 4693 matching the inclined block 4691. The movable groove 1 is provided with a spring 4694 connected to the inclined block 4691. The inner wall of the push block 466 is provided with a Movable groove two, the top block 4692 is slidably arranged in the movable groove two, one end of the top block 4692 extends to the outside of the pushing block 466, a spring two 4695 connected to the top block 4692 is arranged inside the movable groove two, a traction rope one 4696 is arranged between the inclined block one 4691 and the top block 4692, when the top block 4692 contacts the inner wall of the connecting slide 41, the inclined block one 4691 is pulled to move by the traction rope one 4696.

[0029] Specifically, when the connecting rod 42 is inserted into the connecting slide 41, the pushing block 466 can be driven to move by pushing, and at this time, the protrusion 468 on the outer wall of the connecting rod 42 will be inserted into the groove 467, and the inclined block 4691 in the groove 467 will automatically be inserted into the limit opening 4693, meshing the protrusion 468 with the groove 467. At this time, if the connecting rod 42 needs to be pulled out from the connecting slide 41, it means that this movable plate 4 needs to be used, so the support bar 6 needs to be completely stored in the inner cavity 45 of the movable plate 4. At this time, the connecting rod 42 is pulled outward, and since the protrusion 468 is meshed with the groove 467, the pushing block 466 will be reset as the connecting rod 42 moves, and in this process, the rotation of the bidirectional screw rod 461 will drive the support bar 6 to be stored in the inner cavity 45 of the movable plate 4 5, when the support bar 6 is completely stored, the top block 4692 on the pushing block 466 will move to contact the inner wall of the end of the connecting slide 41, and according to the action of force, the top block 4692 will be squeezed and moved into the movable groove 2, and the top block 4692 will pull the traction rope 1 4696 to move. Since the other end of the traction rope 1 4696 is connected to the inclined block 1 4691 and is always in a straight state, the traction rope 1 4696 will pull the inclined block 1 4691 to move inside the movable groove 1, so that it is pulled out from the limit opening 4693, thereby separating the protrusion 468 from the groove 467. At this time, the connecting rod 42 cannot generate pulling force on the pushing block 466. After the two are separated, the connecting rod 42 continues to move backward until it leaves the connecting slide 41, thereby completing the purpose of removing this end of the movable plate 4 from the bed body 1.

[0030] The linkage member 8 includes a connecting seat 81, which is slidably arranged at the bottom of the bed board 2. The connecting frame 7 is C-shaped, and the end of the connecting frame 7 is hinged to the connecting seat 81. The bottom of the bed board 2 is provided with a second slide groove matching the connecting seat 81. The inside of the bed board 2 is provided with a second inner cavity 83. One end of the connecting seat 81 extends into the second inner cavity 83 and is connected to a second connecting rod 82. The second connecting rod 82 is connected to the transfer plate 3. When the transfer plate 3 moves, it drives the second connecting rod 82 to move.

[0031] Specifically, when the transfer board 3 is pulled outward, it will drive the connecting rod 2 82 to move, the connecting rod 42 will drive the connecting seat 81 to move, and the connecting seat 81 will drive the connecting frame 7 to move, so that the connecting frame 7 moves synchronously with the transfer board 3, so that the other end of the connecting frame 7 moves, and will not affect the disassembly of this end of the movable board 4. Because generally when the transfer board 3 is pulled to one side, the movable board 4 and the end on the opposite side will be removed from the bed board 2, so the connecting frame 7 is also moved out of the range of this end to prevent the connecting frame 7 from affecting the use of the movable board 4, and when the transfer board 3 is reset, the connecting frame 7 will also be reset synchronously. In this process, the connecting frame 7 will drive the inclined movable board 4 to rotate, so that the movable board 4 can reach a position as horizontal as possible with the bed board 2, which is convenient for the user to fix the movable board 4 again, and the user cannot squat or go around to the other side to reset the movable board 4, which saves time and effort and is quick to operate.

[0032] A guide track 84 is provided at the bottom of the bed board 2, and a gear 2 85 rotatably connected to the outer wall of the connecting frame 7 is provided through a rotating shaft. The gear 2 85 extends into the guide track 84, and racks 2 86 are provided at both ends of the inner wall of the guide track 84, and the teeth of the two racks 2 86 are opposite. When the gear 2 85 is engaged with the two racks 2 86, the rotation directions are opposite.

[0033] Specifically, when the connecting seat 81 moves, it will drive the connecting frame 7 to move, and the connecting frame 7 will drive the gear 2 85 to engage with the rack 2 86, so that the gear 2 85 rotates. Since the gear 2 85 is sleeved on the outer wall of the rotating shaft, and the rotating shaft is fixedly connected to the connecting frame 7, the gear 2 85 will drive the connecting frame 7 to rotate at this time to adjust the direction of the connecting frame 7. Because the connecting frame 7 is C-shaped, when it moves to one end, the cross bar range of the connecting frame 7 is on the outside of the movable plate 4, which will not affect the movable plate 4 from being fully adjusted to the vertical ninety degrees. Therefore, in the early stage of the movement of the connecting frame 7, its angle needs to be adjusted so that when it moves to one end, the cross bar part of the connecting frame 7 is located on the outside of the movable plate 4.

[0034] In a preferred embodiment, the two sets of racks 86 disposed at both ends of the guide rail drive the gear 85 to rotate in opposite directions when meshing with the gear 85, so as to achieve the purpose of adjusting the crossbar position of the connecting frame 7.

[0035] A base 9 is provided under the bed 1, and a lifting cylinder 10 is provided between the base 9 and the bed 1, and the cylinder controls the lifting of the bed 1. Universal wheels are provided at the bottom of the base 9; fence plates 11 are provided on both sides of the bed 1, and the fence plates 11 are hinged to the bed 1.

[0036] Working principle: the patient lies on the transfer board 3, which is moved to one side of the examination bed, and the lifting cylinder 10 is used to control the lifting of the transfer board 3 so that it is at the same horizontal plane as the examination bed. After opening the fence board 11, the transfer board 3 is translated to move the patient to the examination bed. At this time, when opening the fence board 11, the end of the movable board 4 on the side where the medical staff or family members stand can be opened at the same time. At this time, as the transfer board 3 moves, the movable board 4 will gradually open to form a passage 5. At this time, the medical staff or family members can walk through the passage 5 to provide protection and assistance to the patient all the time, thereby achieving the purpose of continuously protecting the patient and reducing the risk of accidents to the patient; as the transfer board 3 is reset, the movable board 4 is also reset to the position spliced ​​with the bed board 2. At this time, several support bars 6 can be adjusted to a position spanning two adjacent movable boards 4, thereby improving the stability of the movable board 4 after splicing and ensuring the safety of the transfer bed.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
