Description

Technical Field

[0001] The utility model relates to the technical field of medical beds, in particular to a bed capable of adapting to waist and back support. Background Art

[0002] A hospital bed generally refers to a nursing bed, which is designed according to the patient's treatment needs and bedridden lifestyle. It allows family members to accompany the patient and has multiple nursing functions and operation buttons. It uses an insulated and safe bed, such as weight monitoring, back-lifting for dining, intelligent turning over, prevention of bedsores, negative pressure bedwetting alarm monitoring, mobile transportation, rest, rehabilitation (passive movement, standing), drug administration and infusion, etc. Rehabilitation beds can be used alone or in conjunction with treatment or rehabilitation equipment.

[0003] The existing hospital beds have the function of supporting the patient's back through the backrest, but the existing backrest is an integral setting, and the backrest can only adjust the support angle. After the patient's back leans on the backrest, it is easy for the waist or back to not be in close contact with the backrest, resulting in a decrease in the support effect and failing to provide a better experience for the patient. In addition, the support beams on the inner side of the existing backrest are generally welded, which is not convenient for installation and disassembly. Therefore, in response to the above problems, a hospital bed that can adapt to waist and back support is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0024] Example

[0025] like Figure 1-5As shown, a hospital bed that can adapt to lumbar and back support includes a support leg 1 and an inner beam 8. The top of the support leg 1 is fixedly connected to a bed frame 2, one end of the bed frame 2 is fixedly connected to an operation panel 3, the head of the bed frame 2 is rotatably connected to a connecting frame 4, the inner side of the connecting frame 4 is fixedly connected to a connecting beam 5, there are two connecting beams 5, and they are symmetrically distributed on both sides of the vertical center line of the connecting frame 4, the opposite surfaces of the two connecting frames 4 are arranged in a row with a card slot 6, one end of the connecting beam 5 is engaged with a support beam 7, both ends of the support beam 7 are provided with a limiting mechanism, and the limiting mechanism is engaged with the connecting frame 4 through the card slot 6, and the inner side of the support beam 7 is provided with an auxiliary support mechanism.

[0026] As a further improvement of the present invention, Figure 2 、 Figure 3 and Figure 4 As shown, the limiting mechanism includes a limiting pin 18 that is slidably connected to the support beam 7, and the limiting pin 18 is engaged with the connecting beam 5 through the slot 6. One end of the limiting pin 18 is fixedly connected to the connecting block 16, and one end of the connecting block 16 is fixedly connected to the dial plate 15. The dial plate 15 and the connecting block 16 can be used to retract the limiting pin 18 to the inner side of the support beam 7, and then the support beam 7 can be placed on the inner side of the connecting frame 4, and the limiting pin 18 is aligned with the slot 6. Then, the connecting block 16 is engaged with the connecting frame 4 through the slot 6 with the limiting pin 18, thereby fixing the support beam 7 and the connecting frame 4 together, thereby realizing rapid installation of the support beam 7 and facilitating subsequent maintenance and replacement.

[0027] As a further improvement of the present invention, Figure 3 and Figure 4 As shown, one end of the shift plate 15 is fixedly connected to a spring 17, and the spring 17 is fixedly connected to the support beam 7. The shift plate 15 facilitates the movement of the connecting block 16. At the same time, under the elastic force of the spring 17, the shift plate 15 and the connecting block 16 can support the limit pin 18 to prevent the limit pin 18 from accidentally moving out from the inner side of the slot 6.

[0028] As a further improvement of the present invention, Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the auxiliary support mechanism includes an inner beam 8 that is slidably connected to the support beam 7, a motor 9 is fixedly connected to the inner side of the bottom end of the support beam 7, a screw 10 is fixedly connected to the end of the main shaft of the motor 9, and the screw 10 is spirally connected to the support beam 7, and a start-stop component is provided on the inner side of the inner beam 8. After the patient leans on one side of the support beam 7 and the inner beam 8, the patient can use multiple control switches provided on the operation panel 3. Each control switch can individually control the movement of each inner beam 8 to ensure that the patient's back or waist can be supported by the support beam 7 and the inner beam 8, thereby improving the patient's comfort, meeting the usage needs of different patients, and improving the applicability of the device.

[0029] As a further improvement of the present invention, Figure 1 、 Figure 2 As shown, the connecting frame 4, connecting beam 5, supporting beam 7 and inner beam 8 form a backboard, and an electric hydraulic rod is provided at the bottom of the backboard to enable the connecting frame 4 to rotate around the bed frame 2. At the same time, the backboard can support the patient.

[0030] As a further improvement of the present invention, Figure 5 As shown, the start-stop assembly includes a fixed shaft 11 fixedly connected to the support beam 7, the other end of the fixed shaft 11 is fixedly connected to a connecting plate 12, and the connecting plate 12 is slidably connected to the inner beam 8, and a first limit switch 13 and a second limit switch 14 are provided above and below the connecting plate 12, and the first limit switch 13 and the second limit switch 14 are both fixedly connected to the inner beam 8. When the connecting plate 12 touches the first limit switch 13, the motor 9 stops working, and the inner beam 8 is completely retracted to the inner side of the support beam 7. When the connecting plate 12 touches the second limit switch 14, the motor 9 stops working to prevent the inner beam 8 from moving out from the inner side of the support beam 7.

[0031] Working process: The limiting pin 18 can be retracted to the inner side of the support beam 7 by the dial plate 15 and the connecting block 16, and then the support beam 7 is placed on the inner side of the connecting frame 4, and the limiting pin 18 is aligned with the card slot 6. Then, the connecting block 16 with the limiting pin 18 is engaged with the connecting frame 4 through the card slot 6, so that the support beam 7 and the connecting frame 4 are fixed together, thereby realizing the rapid installation of the support beam 7 and facilitating the subsequent maintenance and replacement. At the same time, under the elastic force of the spring 17, the limiting pin 18 can be supported by the dial plate 15 and the connecting block 16 to prevent the limiting pin 18 from accidentally moving out of the inner side of the card slot 6.

[0032] After the backboard is lifted to a certain angle by the electric hydraulic rod, the patient can lean on the support beam 7 and the inner beam 8. After the patient leans on one side of the support beam 7 and the inner beam 8, the patient can use multiple control switches provided on the operation panel 3. Each control switch can individually control the operation of the motor 9 of the inner beam 8, so that the motor 9 moves the corresponding inner beam 8 through the screw 10, ensuring that the patient's back or waist can be supported by the support beam 7 and the inner beam 8, thereby improving the patient's comfort, meeting the usage needs of different patients, and improving the applicability of the device.
