Description

Technical Field

[0001] The present invention relates to the technical field of nursing transfer beds, and more specifically to a transfer bed used for critical care. Background Art

[0002] Critical illness usually refers to a disease that is more serious and requires emergency treatment or hospitalization, such as acute respiratory distress syndrome, severe myocarditis, and acute liver failure. For critical illness, doctors usually take emergency treatment measures, such as ventilator support and intensive care, to restore the patient's health as soon as possible. During critical illness treatment and care, the patient's position needs to be moved, and a movable nursing bed is generally used to assist in patient transfer; A transfer bed is a special medical bed used to transfer patients between beds. It is used to transfer patients from the operating table to the ward and from the ambulance. The use of the transfer bed solves the difficulty of transferring patients from the operating table to the ward after surgery and reduces the pain and difficulty caused to patients by traditional hand-lifting. Therefore, today's transfer beds are essential medical equipment in hospitals. When a transfer bed is used for transfer, the transfer bed board will extend under the patient on the bed. At this time, the patient is located above the transfer bed board. The transfer bed board and the patient above it are retracted onto the transfer bed. After the patient is transported away by the transfer bed, the transfer bed board is extended again to place the patient on the bed. However, in this way, the transfer bed board and the bed are in a parallel state during transfer, so it is not conducive to moving the patient from the bed or moving the patient to the bed. If there is a certain distance between the transfer bed board and the bed, the patient will shake, which is not conducive to protecting the patient. When the transfer bed is being transferred, the bed board needs to be extended. After the bed board is extended, the center of gravity of the transfer bed will shift. If the patient is heavy, there is a possibility of the transfer bed tipping over. In order to prevent the transfer bed from tipping over, additional medical staff need to be dispatched to take care of the transfer bed, which wastes medical resources. In addition, since the bed board of the transfer bed will be extended, it is easy to shake. The bed board on the transfer bed is tightly connected to the bed body, so it is more difficult to clean.

The side of the support bed board 3 is fixedly connected to the bottom of the support frame 4, and the fixed outer frame 511 in the transfer mechanism 5 is fixedly connected to the top of the support bed board 3 to ensure its overall stability. In addition, the support frame 4 and the fixed outer frame 511 are both provided with a fence to prevent the patient from falling. Figure 3 In the state of the present application during transportation, the support mechanism 8 will rotate 180 degrees along with the bed baffle 7 to provide support.

[0027] Reference Figure 4as well as Figure 5 The transfer mechanism 5 includes a servo motor 501 that can provide power. The top of the servo motor 501 is fixedly connected to an output shaft 502. The top of the output shaft 502 is fixedly connected to a first bevel gear 503. The side of the first bevel gear 503 is meshed with a second bevel gear 504. The side of the second bevel gear 504 away from the first bevel gear 503 is fixedly connected to a threaded rod 505. The side of the threaded rod 505 is threadedly connected to a first moving block 506. The side of the threaded rod 505 is fixedly connected to a connecting shaft 507. The side of the connecting shaft 507 is movably sleeved with a transfer bed board 508. The top of the supporting bed board 3 is provided with an inclined surface. The side of the threaded rod 505 away from the second bevel gear 504 is fixedly connected to a limiting mechanism 9. When the first moving block 506 contacts the limiting mechanism 9, the connecting shaft 507 is completely located. Above the inclined surface of the supporting bed board 3, both sides of the supporting bed board 3 are fixedly connected with a fixed outer frame 511, and the side of the connecting shaft 507 away from the first moving block 506 is fixedly connected with the second moving block 510. The second moving block 510 is internally movably connected with a limiting rod 509, one side of the limiting rod 509 is fixedly connected to the side of the limiting mechanism 9, and the other side of the limiting rod 509 is fixedly connected to the inside of the fixed outer frame 511. There are two limiting mechanisms 9. The interior of the supporting frame 4 is provided with a avoiding groove for the first bevel gear 503 and the second bevel gear 504 to operate, the top of the servo motor 501 is fixedly connected to the bottom of the supporting frame 4, and the side of the fixed outer frame 511 close to the supporting bed board 3 is provided with a sliding groove for the first moving block 506 to move.

[0028] In the embodiment of the present application, when a patient is transferred, the first moving block 506 moves on the side of the threaded rod 505, which will drive the connecting shaft 507 and the transfer bed board 508 to move. When the transfer bed board 508 is moved to the hospital bed, the connecting shaft 507 is completely located above the inclined surface of the supporting bed board 3. Therefore, the transfer bed board 508 can rotate around the connecting shaft 507 at this time. After the transfer bed board 508 rotates, it will tilt, which is convenient for moving the patient. The first moving block 506 and the second moving block 510 are respectively provided on both sides of the connecting shaft 507, so that the connecting shaft 507 is more stable when moving, and the number of fixed outer frames 511 is two, and The two fixed outer frames 511 are respectively located on both sides of the transfer bed board 508. The fixed outer frames 511 can provide the first moving blocks 506 and 610 with support for the patient while they are moving. The sides of the threaded rod 505 and the limiting rod 509 are provided with limiting mechanisms 9. The two limiting mechanisms 9 can cooperate with the two sides of the transfer bed board 508 to ensure that the transfer bed board 508 will not collapse as a whole, so that the patient can lie more comfortably on the top of the transfer bed board 508. When the transfer bed board 508 itself rotates upward around the connecting shaft 507, the supporting bed board 3 is completely exposed to the outside, which is convenient for cleaning the supporting bed board 3 and the transfer bed board 508.

[0029] Reference Figure 5 , Figure 6 as well as Figure 7 The limiting mechanism 9 includes a limiting frame 901 fixedly connected to the limiting rod 509, an electromagnet 902 is fixedly connected to the bottom end of the limiting frame 901 near the side of the transfer bed board 508, a magnetic plate 903 is provided on the side of the electromagnet 902, and limiting grooves compatible with the magnetic plate 903 are opened on both sides of the transfer bed board 508. When the magnetic plate 903 contacts the electromagnet 902, the magnetic plate 903 is located in the limiting groove of the transfer bed board 508, and the side of the magnetic plate 903 away from the electromagnet 902 is fixedly connected to a fixing rod 904, and the side of the fixing rod 904 away from the magnetic plate 903 is movably connected to a fixing sleeve 905, and the side of the fixing sleeve 905 away from the fixing rod 904 is fixedly connected to the inside of the limiting frame 901, and the sides of the fixing rod 904 and the fixing sleeve 905 are provided with supporting springs 906.

[0030] In the embodiment of the present application, when the transfer bed board 508 is located as a whole above the supporting bed board 3, the magnetic plate 903 is located in the limiting groove of the transfer bed board 508, ensuring that the position of the transfer bed board 508 will not change and the stability of the transfer bed board 508 is ensured. When the transfer bed board 508 needs to be moved, the electromagnet 902 is energized and generates a magnetic repulsion force with the magnetic plate 903, so that the magnetic plate 903 will move from the transfer bed board 508, and after it is removed, the electromagnet 902 can be powered off and reset by the compressed support spring 906, thereby saving energy.

[0031] 6. Referring to the figure, the rotating mechanism 6 includes a connecting block 601 fixedly connected to the outer side of the fixed outer frame 511, a limiting hole matched with the limiting block 605 is opened at the top of the connecting block 601, a connecting plate 604 is movably connected to the side of the limiting block 605, a connecting baffle 603 is fixedly connected to the side of the connecting plate 604, a connecting frame 606 is fixedly connected to the side of the limiting block 605, and the connecting frame 606 is located below the connecting plate 604, a fixed shaft 602 is movably connected inside the connecting baffle 603, and the side of the fixed shaft 602 is fixedly connected to the side of the connecting block 601, and the sides of the connecting baffle 603 and the bed baffle 7 are fixedly connected with a bearing block 607, and when the connecting frame 606 is located inside the limiting hole of the connecting block 601, the bearing block 607 is located above the inclined surface of the supporting bed board 3, and the top of the bearing block 607 contacts the bottom end of the transfer bed board 508, and the bottom end of the bearing block 607 contacts the top of the supporting bed board 3.

[0032] In the embodiment of the present application, when transfer is not performed, the limit block 605 is inserted into the limit hole of the connecting block 601 to prevent the patient from falling. When transfer is required, the limit block 605 can be removed from the connecting block 601. At this time, the connecting baffle 603 and the bed baffle 7 can both rotate around the fixed axis 602 to avoid position, which is convenient for transfer. A connecting frame 606 is provided on the side of the limit block 605. Therefore, when the connecting baffle 603, the connecting plate 604 and the bed baffle 7 rotate, the rotating limit block 605 will not fall from the connecting plate 604. During transportation after transfer, the load-bearing block 607 will enter between the supporting bed board 3 and the transfer bed board 508 to support the transfer bed board 508.

[0033] Reference Fig. 9 as well as Fig.10 A placement groove is provided at the top of the bed baffle 7, and the first support plate 801 and the second support plate 802 are movably connected in the placement groove of the bed baffle 7 from bottom to top. The support mechanism 8 includes a first support plate 801 and a second support plate 802. The side of the second support plate 802 is movably connected with a limiting shaft 803, and the side of the limiting shaft 803 is fixedly connected with a blocking piece 804. The side of the limiting shaft 803 is movably connected with a limiting spring 806, and the side of the limiting shaft 803 away from the second support plate 802 is fixedly connected with a ball 805.

[0034] In the embodiment of the present application, during transportation, the ball 805 is pulled outward, and when the ball 805 is pulled outward, the baffle 804 and the limit shaft 803 move synchronously, and the limit shaft 803 moves from the second support plate 802, and the baffle 804 compresses the limit spring 806, and the second support plate 802 and the first support plate 801 in the bed baffle 7 are rotated downward in sequence, so that the first support plate 801 and the second support plate 802 are in contact with the ground for support, and the first support plate 801 and the second support plate 802 are staggered with each other, so they will not disturb each other during rotation, and when the first support plate 801 is rotated out of the bed baffle 7, the limit shaft 803 will be removed from the placement groove of the bed baffle 7 to ensure that the first support plate 801 can be rotated ninety degrees.

[0035] Working principle of the present invention: during transportation, the present invention is moved as a whole to the side of the bed, the lifting mechanism 2 is adjusted so that the transport bed board 508 is located above the bed, the limit block 605 is pulled upward, and the bottom end of the limit block 605 moves from the connecting block 601. At this time, the connecting baffle 603 and the bed baffle 7 rotate 180 degrees around the fixed axis 602, and the ball 805 is pulled outward. When the ball 805 is pulled outward, the baffle 804 and the limit shaft 803 move synchronously, and the limit shaft 803 moves from the second support plate 802. The baffle 804 compresses the limit spring 806, and the second support plate 802 and the first support plate 801 in the bed baffle 7 are rotated downward in turn, so that the first support plate 801 and the second support plate 802 are in contact with the ground for support, such as Figure 3 As shown; The side where the support mechanism 8 of the present invention is located contacts the side of the hospital bed, and the electromagnet 902 is energized to generate magnetic repulsion between the magnetic plate 903, so that the magnetic plate 903 moves out of the limit grooves on both sides of the transfer bed plate 508 and compresses the support spring 906, the servo motor 501 starts and drives the first bevel gear 503 to rotate through the output shaft 502, when the first bevel gear 503 rotates, it drives the threaded rod 505 to rotate through the second bevel gear 504, when the threaded rod 505 rotates, the first moving block 506 moves, the first moving block 506 drives the transfer bed plate 508 to move horizontally above the support bed plate 3 through the connecting shaft 507, and the transfer bed plate 508 moves above the hospital bed; When the transfer bed plate 508 moves to the limit mechanism 9 and contacts the transfer bed plate 508 as a whole, the transfer bed plate 508 is located above the inclined surface of the support bed plate 3, so the transfer bed plate 508 will rotate around the connecting shaft 507, so the transfer bed plate 508 itself will tilt. Figure 3 As shown, the patient can be moved to the inclined transfer bed plate 508 at this time. The inclined transfer bed plate 508 is convenient for the patient to move. After the patient moves to the top of the transfer bed plate 508, the servo motor 501 controls the threaded rod 505 to reverse. At this time, the transfer bed plate 508 moves in the opposite direction to move the patient to the top of the supporting bed plate 3. The transfer bed plate 508 will be in a horizontal position again when it moves. After the patient and the transfer bed board 508 are all located on the square of the supporting bed board 3, the first supporting plate 801 and the second supporting plate 802 are retracted into the bed body baffle 7, and the limiting spring 806 is reset to make the limiting shaft 803 move to the second supporting plate 802. The limiting shaft 803 is used to limit the bed body baffle 7 and the connecting baffle 603 is rotated 180 degrees again. The limiting block 605 is inserted into the connecting block 601, and the bearing block 607 enters the inclined surface of the supporting bed board 3 to support the transfer bed board 508. The electromagnet 902 is powered off, and the supporting spring 906 is reset to make the magnetic plate 903 enter the transfer bed board 508 to limit the transfer bed board 508 to ensure that the transfer bed board 508 does not shake. When cleaning, the electromagnet 902 is energized. At this time, the transfer bed board 508 rotates upward, and the first moving block 506 drives the transfer bed board 508 to move, so as to facilitate the thorough cleaning of the transfer bed board 508 and the supporting bed board 3.

[0036] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
