Description

Technical Field

[0001] This utility model relates to the field of examination bed technology, and in particular to an examination bed with a replaceable liner of fixed length. Background Technology

[0002] The examination bed is equipped with disposable sheets at both ends. The sheets need to be replaced after each patient's use. In the relevant technology, the two ends of the examination bed are equipped with drive wheels and driven rollers respectively. The sheets are transferred unidirectionally between the drive shaft and the driven rollers. The patient lies on or sits on the sheets for the examination. The sheets are automatically replaced after the examination.

[0003] Currently, when changing the sheets on examination beds, medical staff rely solely on their sense of touch to ensure that used sheets have been completely rolled up and that the new sheets are brand new and unused. However, this manual judgment is prone to significant errors, as it cannot definitively determine whether the new sheets are truly new and unused, and excessive rolling up can lead to waste.

[0004] Therefore, this application proposes a technical solution to solve the above problems. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an examination bed with a fixed-length replaceable liner, which can automatically replace the liner and replace it at a fixed length. This not only reduces the labor intensity of medical staff, but also ensures that the liner re-laid on the examination bed is brand new and unused, ensuring the cleanliness of the liner, and also avoids the waste caused by the liner being over-rolled.

[0006] An examination bed with a replaceable liner of fixed length according to an embodiment of the present invention includes:

[0007] A bed frame, wherein a first roller and a second roller are respectively provided at both ends of the bed frame, and one end of the first roller is connected to a first driving member for transmission.

[0008] A sheet is laid on the bed frame, with one end of the sheet wrapped around the first roller and the other end wound around the second roller;

[0009] A fixed-length detection device includes a detector and a rotating wheel. The rotating wheel is rotatably connected to the bed frame and is located at either end of the bed frame. The outer circumferential wall of the rotating wheel can abut against the pad. The detector is electrically connected to the first driving component. The rotating wheel can rotate under the drive of the pad. The detector can obtain the number of rotations of the rotating wheel to determine the conveying length of the pad.

[0010] The first drive unit can automatically stop the machine by obtaining the number of rotations of the rotating wheel from the detector, thereby realizing the fixed-length replacement of the pad.

[0011] An inspection bed with a fixed-length replaceable sheet according to an embodiment of the present invention has at least the following beneficial effects: The first roller, the second roller, and the first drive unit in the inspection bed provided by this application together constitute an automatic sheet winding and unwinding device. The first drive unit drives the first roller to rotate to wind up the used sheet, while the second roller rotates under the drive of the sheet to unwind the unused sheet, thereby realizing automatic sheet replacement. Furthermore, through the cooperation of the drive unit and the fixed-length detection device, the inspection bed can automatically detect the conveying length of the sheet and automatically stop after reaching the set length, realizing fixed-length sheet replacement.

[0012] Understandably, the rotating wheel in the fixed-length detection device abuts against the sheet. When the sheet moves, it drives the rotating wheel to rotate. Simultaneously, the detector monitors the number of rotations of the rotating wheel to determine the conveying length of the sheet. That is, according to the setup of the examination bed system, when only half a sheet needs to be replaced (i.e., half of the sheet laid on the bed frame is replaced), once the detector detects that the number of rotations of the rotating wheel has reached a preset value, the detector sends feedback to the examination bed system. The system then sends a command to the first drive unit, which stops, completing the replacement of half a sheet. Similarly, if the entire sheet laid on the examination bed is replaced, the detector should detect twice the number of rotations of the rotating wheel compared to when replacing half a sheet.

[0013] This application utilizes a drive mechanism and a length-fixed detection device to automatically detect the conveying length of the examination bed drape and automatically stop the machine when the set length is reached, thus achieving fixed-length drape replacement. This not only improves the speed of drape replacement and reduces the workload of medical staff, but also ensures that the drapes re-laid on the examination bed are brand new and unused, guaranteeing the cleanliness of the drapes and preventing waste caused by excessive winding of the drapes.

[0014] According to an embodiment of the present invention, an inspection bed with a replaceable liner of fixed length includes a detection bracket and a detection block. The detection bracket is fixed on the bed frame, the detection block is connected to the rotating wheel, and the detector is installed on the detection bracket. The rotating wheel can drive the detection block to rotate simultaneously, so that the detection block can enter or leave the detection range of the detector.

[0015] According to an embodiment of the present invention, an inspection bed with a replaceable liner of fixed length includes a connecting shaft, which is rotatably connected to the bed frame. The detection block and the rotating wheel are fixedly connected to the connecting shaft, and the detection block and the rotating wheel are arranged along the axial extension direction of the connecting shaft.

[0016] According to an embodiment of the present invention, an inspection bed with a replaceable pad of fixed length includes a detection bracket comprising a mounting plate and a first rod disposed on the mounting plate. The first rod is disposed on the same side as the detection block, and the detector is mounted on the first rod.

[0017] According to an embodiment of the present invention, an inspection bed with a replaceable pad of fixed length is provided on the mounting plate. The two first rods are arranged opposite to each other, and a detection channel is formed between the two first rods for the detection block to pass through. The detector is disposed on at least one or both of the two first rods and is located within the detection channel.

[0018] According to an embodiment of the present invention, an inspection bed with a replaceable liner of fixed length is provided, wherein the inspection block is a semi-circular plate.

[0019] According to an embodiment of the present invention, an inspection bed with a replaceable liner of fixed length includes a rotating wheel body and a protrusion disposed on the roller body, the protrusion being able to abut against the liner.

[0020] According to an embodiment of the present invention, an inspection bed with a replaceable pad of fixed length has a plurality of protrusions arranged circumferentially around the axis of the roller body, and the protrusions can take turns abutting against the pad in sequence.

[0021] According to an embodiment of the present invention, an examination bed with a replaceable liner of fixed length is provided, wherein the intersection of the edges of the protrusions is an angular shape.

[0022] According to an embodiment of the present invention, an examination bed with a replaceable liner of fixed length is provided, wherein a foldable lifting device is installed at the bottom of the bed frame, and the lifting device is used to realize the position change of the bed frame in the vertical direction.

If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] Reference Figures 1 to 3 This utility model provides an inspection bed with a fixed-length replaceable sheet, including a bed frame 100, with a first roller 200 and a second roller 300 respectively provided at both ends of the bed frame 100. One end of the first roller 200 is connected to a first drive member 600. A sheet 400 is laid on the bed frame 100, with one end of the sheet 400 wrapped around the first roller 200 and the other end wound around the second roller 300. A fixed-length detection device 500 includes a detector 570 and a rotating wheel 510. The rotating wheel 510 is rotatably connected to the bed frame 100 and is located at either end of the bed frame 100. The outer circumference of the rotating wheel 510 can abut against the sheet 400. The detector 570 is electrically connected to the first drive member 600. The rotating wheel 510 can rotate under the drive of the sheet 400. The detector 570 can obtain the number of rotations of the rotating wheel 510 to determine the conveying length of the sheet 400.

[0040] The first driving component 600 can automatically stop the machine by obtaining the number of rotations of the rotating wheel 510 from the detector 570, thereby realizing the fixed-length replacement of the pad 400.

[0041] The first roller 200, second roller 300, and first drive unit 600 in the inspection bed provided in this application together constitute an automatic winding and unwinding device for the sheet 400. The first drive unit 600 drives the first roller 200 to rotate, thereby winding up the used sheet 400. The second roller 300 rotates under the influence of the sheet 400, thereby unwinding the unused sheet 400, thus achieving automatic replacement of the sheet 400. Furthermore, through the cooperation of the drive unit and the fixed-length detection device 500, the inspection bed can automatically detect the conveying length of the sheet 400 and automatically stop when the set length is reached, achieving fixed-length replacement of the sheet 400.

[0042] Understandably, the first roller 200 is wound with the used sheet 400, and is connected to the drive unit, responsible for collecting the used sheet 400; while the second roller 300 is wound with the unused sheet 400, responsible for releasing the unused sheet 400. The rotating wheel 510 in the fixed-length detection device 500 abuts against the sheet 400. When the sheet 400 moves, it drives the rotating wheel 510 to rotate. Simultaneously, the detector 570 monitors the number of rotations of the rotating wheel 510, determining the conveying length of the sheet 400 based on the number of rotations. That is, according to the settings of the examination bed system, when only half of the sheet 400 needs to be replaced, that is, when half of the sheet 400 laid on the bed frame 100 is replaced, when the detector 570 detects that the number of rotations of the rotating wheel 510 has reached the preset value, the detector 570 can feed back to the examination bed system, and the system sends a command to the first drive unit 600. At this time, the first drive unit 600 can stop to complete the replacement of half of the sheet 400. Similarly, if the entire sheet 400 laid on the examination bed is replaced, the detector 570 should detect that the number of rotations of the rotating wheel 510 is twice that of the former when half of the sheet 400 is replaced.

[0043] Optionally, the length detection device 500 may be located at one end near the second roller 300; or at one end near the first roller 200; or the length detection device 500 may be located near both the first roller 200 and the second roller 300. The user can choose according to the actual situation.

[0044] Furthermore, the first roller 200 is directly controlled by the first drive component 600, and the second roller 300 acts as a driven wheel to form tension balance, ensuring that the pad 400 is conveyed smoothly.

[0045] Specifically, as shown in the figure, the fixed-length detection device 500 includes a detection bracket, a connecting shaft 530, a detection block 520, and a rotating wheel 510. The detection bracket is fixed on the bed frame 100, and the connecting shaft 530 is rotatably connected to the bed frame 100. The detection block 520 and the rotating wheel 510 are both fixedly connected to the connecting shaft 530, and the detection block 520 and the rotating wheel 510 are arranged along the axial extension direction of the connecting shaft 530. Furthermore, the detection bracket consists of a mounting plate 540 and a first rod 550 disposed on the mounting plate 540. Specifically, the first rod 550 is disposed on the same side as the detection block 520, and the detector 570 is mounted on the first rod 550. At the same time, as shown in the figure, two first rods 550 are disposed on the mounting plate 540, which are disposed opposite to each other, and a detection channel 560 is formed between the two first rods 550, which allows the detection block 520 to pass through. The detector 570 is disposed on at least one or both of the two first rods 550, and the detector 570 is located within the detection channel 560.

[0046] That is, it can be understood that the coaxial design of the rotating wheel 510 and the detection block 520 ensures that the rotating wheel 510 and the detection block 520 rotate synchronously when the sheet 400 moves, forming a reliable mechanical triggering mechanism. Furthermore, the two first rods 550 form a detection channel 560, with the detector 570 located within it. Driven by the rotating wheel 510, the detection block 520 periodically enters / exits the detection channel 560, achieving pulse signal output. The detector 570 determines the number of rotations of the rotating wheel 510 by the number of times the detection block 520 enters and exits the detection channel 560, forming a closed-loop control with the first drive component 600 to achieve fixed-length replacement of the sheet 400. By precisely controlling the replacement length of the sheet 400, the risk of cross-infection is avoided, meeting the requirements of hospital infection control management.

[0047] Optionally, the fixed-length detection device 500 may also be provided with a mounting box 580, which is fixedly connected to the bed frame 100. The mounting box 580 has a notch through which part of the rotating wheel 510 can pass, and the detection bracket, connecting shaft 530, detection block 520, and detector 570 are all disposed inside the mounting box 580. Furthermore, the connecting shaft 530 is rotatably connected to the mounting box 580.

[0048] According to some embodiments of this application, the detection block 520 is a semi-circular plate, which can ensure the detection accuracy of the detector 570 on the detection block 520 and enhance the stability of signal triggering.

[0049] According to some embodiments of this application, the rotating wheel 510 includes a roller body 511 and a protrusion 512 disposed on the roller body 511, the protrusion 512 being able to abut against the pad 400. Specifically, a plurality of protrusions 512 are arranged circumferentially around the axis of the roller body 511, and the protrusions 512 are able to abut against the pad 400 in turn.

[0050] As shown in the figure, the intersection of the end edges of the protrusion 512 is an angular shape, which can increase the friction with the pad 400 and reduce the risk of slippage.

[0051] Furthermore, a flexible silicone layer can be added to the surface of the protrusion 512 to increase friction while reducing physical damage to the pad 400.

[0052] According to some embodiments of this application, a foldable lifting device 110 is installed at the bottom of the bed frame 100. The lifting device 110 is used to realize the vertical position change of the bed frame 100. The lifting device 110 of the examination bed of this application is foldable, which takes into account both the convenience of height adjustment and space utilization, and is suitable for the examination needs of different departments (such as radiology and ultrasound).
