Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a CT examination bed auxiliary structure. Background Art

[0002] Medical devices refer to appliances, equipment, instruments, materials or other items used to prevent, diagnose, treat, or alleviate disease, injury or disability, as well as devices used to regulate the structure and function of the human body. Medical devices play an important role in the field of healthcare, helping medical staff diagnose diseases, conduct treatment and rehabilitation, and improve patients' survival rate and quality of life. Different medical devices are subject to strict supervision and regulation in design, manufacturing and use to ensure their safety and effectiveness.

[0003] When some patients with limited mobility are examined on a CT examination bed, they need to use a transfer bed to carry the patients to one side of the CT examination bed, and then multiple medical staff will move the patients to the CT examination bed. This back and forth transportation is not only time-consuming and labor-intensive, but also easily causes secondary injuries to the patients. For this reason, we propose a CT examination bed auxiliary structure. Utility Model Content

[0004] The purpose of the utility model is to provide a CT examination bed auxiliary structure to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Preferably, lifting slots are provided at the four corners of the top end of the frame, and support rods are fixedly installed at the four corners of the bottom end of the bed board.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. A CT examination bed auxiliary structure is used in conjunction with a transmission shaft, a gear, a tooth block and a movable plate. The patient is transferred to one side of the CT examination bed through the device, and then the first crank is turned. The first crank controls the rotation of the transmission shaft. After the transmission shaft rotates, the gear is driven to rotate. When the gear rotates, the tooth block in the middle of the bottom end of the bed board is controlled to move horizontally. When the tooth block moves horizontally, the movable plate is controlled to move horizontally to the upper end of the CT examination bed and then stop. In this way, there is no need to carry the patient back and forth during the examination, avoiding secondary injuries.

[0016] 2. This CT examination bed auxiliary structure is used in conjunction with a screw rod, a movable sleeve, a connecting rod and a bed board. If the height of the CT examination bed is different, the second crank is held and shaken, and the second crank controls the rotation of the screw rod, and the screw rod drives the movable sleeves at both ends to move in the same direction. In this way, the two cross-arranged connecting rods will lift the bed board, so that the height of the bed board and the movable board can be adjusted until it stops after adapting to the height of the CT examination bed, thereby achieving the purpose of facilitating height adjustment.

[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A CT examination bed auxiliary structure comprises a frame 1, a bed board 2 is movably mounted on the top of the frame 1, a movable board 3 is movably mounted on the top of the bed board 2, a shifting mechanism 4 is arranged between the middle of the bed board 2 and the movable board 3, the shifting mechanism 4 comprises a transmission shaft 401, a gear 402 and a tooth block 403; a transmission shaft 401 is movably mounted on one side of the inner part of the bed board 2, a gear 402 is arranged at one end of the transmission shaft 401 close to the middle of the bed board 2, a first crank 8 is fixedly mounted on the other end of the transmission shaft 401, a tooth block 403 is fixedly mounted on the middle bottom end of the movable board 3, and the tooth block 403 is meshed with the gear 402;

[0026] In this embodiment, the patient is transferred to one side of the CT examination bed through the device, and then the first crank 8 is rotated. The first crank 8 controls the transmission shaft 401 to rotate. After the transmission shaft 401 rotates, it drives the gear 402 to rotate. When the gear 402 rotates, it controls the tooth block 403 in the middle of the bottom end of the bed board 2 to move horizontally. When the tooth block 403 moves horizontally, it controls the movable plate 3 to move horizontally to the upper end of the CT examination bed and then stop. In this way, there is no need to carry the patient back and forth during the examination, avoiding secondary injuries.

[0027] like Figure 2 and Figure 4As shown, an I-shaped frame 5 is arranged between the four sides of the frame 1, a slide 6 is fixedly installed between the top ends of the I-shaped frames 5 on both sides, a lifting mechanism 7 is arranged in the middle of the slide 6, and the lifting mechanism 7 includes a screw rod 701, a movable sleeve 702 and a connecting rod 703; the screw rod 701 is movably installed inside the slide 6, and a second crank 11 is fixedly installed at one end of the screw rod 701 close to the first crank 8, and movable sleeves 702 are movably installed on the outside of both sides of the screw rod 701, and connecting rods 703 are movably installed between the top ends of the two movable sleeves 702 and the bottom end of the bed board 2, and the middle parts of the two connecting rods 703 are movably connected through a rotating shaft; the threads at both ends of the screw rod 701 are opposite;

[0028] In this embodiment, if the height of the CT examination bed is different, the second crank handle 11 is held and shaken, and the second crank handle 11 controls the rotation of the screw rod 701, and the screw rod 701 drives the movable sleeves 702 at both ends to move in the same direction, so that the two cross-arranged connecting rods 703 will lift the bed board 2, so that the height of the bed board 2 and the movable board 3 can be adjusted until it matches the height of the CT examination bed and stops, thereby achieving the purpose of facilitating height adjustment.

[0029] like Figure 2 As shown, guide rods 9 are fixedly installed on both sides of the top of the bed board 2, and movable blocks 10 are arranged on both sides of the left side of the bottom of the movable board 3, and the movable blocks 10 are movably connected to the guide rods 9;

[0030] In this embodiment, when the movable plate 3 moves laterally, the movable blocks 10 at both ends of the left bottom of the movable plate 3 will slide along the outside of the guide rod 9 for guidance.

[0031] like Figure 2 As shown, the four corners of the top of the frame 1 are provided with lifting slots 12, and the four corners of the bottom of the bed board 2 are fixedly installed with support rods 13;

[0032] In this embodiment, when the bed board 2 is raised or lowered, the support rods 13 at the four corners of the bottom end of the bed board 2 will be raised or lowered synchronously along the lifting slots 12 at the four corners of the top end of the frame 1 for guidance.

[0033] Working principle: During operation, the patient is transferred to one side of the CT examination bed through the device, and then the first crank 8 is rotated. The first crank 8 controls the rotation of the transmission shaft 401. After the transmission shaft 401 rotates, it drives the gear 402 to rotate. When the gear 402 rotates, it controls the tooth block 403 in the middle of the bottom end of the bed board 2 to move horizontally. When the tooth block 403 moves horizontally, it controls the movable plate 3 to move horizontally to the upper end of the CT examination bed and then stop. In this way, there is no need to carry the patient back and forth during the examination, thereby avoiding secondary injuries. If the height of the CT examination bed is different, the second crank 11 is held and shaken. The second crank 11 controls the rotation of the screw rod 701. The screw rod 701 drives the movable sleeves 702 at both ends to move in the same direction. In this way, the two cross-arranged connecting rods 703 will lift the bed board 2. In this way, the height of the bed board 2 and the movable plate 3 can be adjusted until it stops after matching the height of the CT examination bed, thereby achieving the purpose of facilitating height adjustment.
