Description

Technical Field

[0001] This application relates to the field of medical auxiliary equipment technology, and in particular to an automatic paper roll holder for ultrasound examination. Background Technology

[0002] During ultrasound examinations at the hospital, in accordance with hospital infection control regulations, patients must have a new towel after each ultrasound examination. Most of the ultrasound examination beds purchased previously did not have an automatic towel rolling function. If all of them were replaced with automatic towel rolling beds, it would not only waste medical equipment and facilities resources, but also significantly increase departmental expenses.

[0003] Currently, the common practice is to place the toilet paper roll at the foot of the bed for manual replacement by the doctor. However, in some examination rooms, due to operational needs, the examination bed cannot be placed close to the wall, and an empty cardboard box must be placed on the floor to hold the toilet paper roll. However, whether the toilet paper roll is placed at the foot of the bed or on the cardboard box, it often shifts when being replaced. This not only increases the difficulty of the doctor's operation but also prolongs the patient's waiting time, affecting the efficiency of the examination and the patient's medical experience. Therefore, an automatic toilet paper holder for ultrasound examinations is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic paper roll holder for ultrasonic examinations to solve the problems mentioned in the background art.

[0005] The automatic paper roll holder for ultrasonic examination provided in this application adopts the following technical solution:

[0006] An automatic paper roll holder for ultrasonic examination includes a fixed base. A vertical rod is fixedly connected to the top outer wall of the fixed base. A movable rod is slidably connected to the outer wall of the vertical rod. A telescopic mechanism is installed between the vertical rod and the movable rod. A rotating shaft is rotatably connected to the top of the movable rod via a bearing seat. A winding motor is fixedly installed on one side outer wall of the bearing seat. The output shaft of the winding motor is fixedly connected to one end of the rotating shaft. An insertion rod is fixedly connected to the end of the rotating shaft opposite to the winding motor. A limit plate is threadedly connected to the outer wall of the insertion rod.

[0007] Preferably, the telescopic mechanism includes a screw block, a lead screw, a second bevel gear, a first bevel gear, and a knob. The lead screw is rotatably connected to the inner wall of the movable rod via a bearing seat. The screw block is clamped to the inner wall of the top of the upright rod via multiple fixing rods. The lead screw is threadedly connected to the inner wall of the screw block.

[0008] Preferably, the second bevel gear is fixedly connected to the top of the lead screw, the first bevel gear is rotatably connected to the inner wall of the movable rod through a transmission shaft and is located above the second bevel gear, the first bevel gear meshes with the second bevel gear, and one end of the transmission shaft passes through the movable rod and is fixedly connected to the knob.

[0009] Preferably, the outer wall of the fixed base has two fixing grooves, and the two fixing grooves are elongated.

[0010] Preferably, a tensioning rod is also fixedly connected to the outer wall of the movable rod. The tensioning rod is located below the insertion rod and is arranged parallel to the insertion rod.

[0011] Preferably, a fixing plate is fixedly connected to the outer wall of one end of the insertion rod near the shaft seat, and the fixing plate corresponds to the limiting plate.

[0012] Preferably, a limiting plate is fixedly connected to one end of the lead screw located inside the upright.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The paper roll holder is securely installed by the fixed base. The fixing plate and limiting plate on the insertion rod can clamp the paper roll to prevent it from moving axially during transportation and replacement. This avoids the situation where the paper roll is easily moved when placed at the end of the bed or in a cardboard box. This allows doctors to reduce the number of operation steps by not having to frequently adjust the position of the paper roll.

[0015] 2. The automatic feeding of the paper roll is driven by a rewinding motor, and the tension rod ensures that the paper roll is fed flat. There is no need for doctors to manually pull and change it. The height can be flexibly adjusted by the telescopic mechanism to adapt to different examination scenarios, optimize the examination process, improve the efficiency of paper roll changing, and thus shorten the patient's waiting time.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses an automatic paper roll holder for ultrasonic examination. (Refer to...) Figure 1-3An automatic paper roll holder for ultrasonic examination includes a fixed base 1 made of metal, which has good stability. The top outer wall of the fixed base 1 is fixedly connected to a vertical rod 2 by welding. The vertical rod 2 has a hollow structure, and a movable rod 3 is slidably connected to its outer wall. The internal shape of the movable rod 3 is adapted to the external shape of the vertical rod 2, and it can slide up and down along the axial direction of the vertical rod 2. A telescopic mechanism is installed between the vertical rod 2 and the movable rod 3. The position of the movable rod 3 relative to the vertical rod 2 can be adjusted by the telescopic mechanism, thereby adjusting the height of the entire paper roll holder.

[0022] The top of the movable rod 3 is rotatably connected to the rotating shaft 5 via the bearing seat 4. The bearing seat 4 is fixed to the top of the movable rod 3 by bolts. The rotating shaft 5 can rotate freely within the bearing seat 4. A winding motor 6 is fixedly installed on one side of the outer wall of the bearing seat 4 by bolts. The winding motor 6 is a servo motor. Its output shaft is fixedly connected to one end of the rotating shaft 5 via a coupling. When the winding motor 6 is working, it can drive the rotating shaft 5 to rotate. The end of the rotating shaft 5 away from the winding motor 6 is fixedly connected to the insertion rod 7 by welding. The outer wall of the insertion rod 7 is provided with external threads. The outer wall thread is connected to the limit plate 8. The limit plate 8 is provided with internal threads that match the insertion rod 7.

[0023] The telescopic mechanism includes a screw block 12, a lead screw 13, a second bevel gear 17, a first bevel gear 16, and a knob 18. The lead screw 13 is rotatably connected to the inner wall of the movable rod 3 via a second bearing seat 14. The second bearing seat 14 is fixed to the inner wall of the movable rod 3, and the lead screw 13 can rotate within the second bearing seat 14. The screw block 12 is snapped onto the inner wall of the top of the upright rod 2 via multiple fixing rods. One end of the fixing rod is welded to the screw block 12, and the other end is welded to the inner wall of the upright rod 2. The lead screw 13 is threadedly connected to the inner wall of the screw block 12, and the screw block 12 has an internal thread that matches the lead screw 13.

[0024] The second bevel gear 17 is fixedly connected to the top of the lead screw 13 via a key connection. The first bevel gear 16 is rotatably connected to the inner wall of the movable rod 3 via a transmission shaft 15. Both ends of the transmission shaft 15 are connected to the inner wall of the movable rod 3 via bearings, and the first bevel gear 16 is located above the second bevel gear 17. The first bevel gear 16 meshes with the second bevel gear 17. One end of the transmission shaft 15 passes through the movable rod 3 and is fixedly connected to the knob 18 by welding. Rotating the knob 18 can drive the transmission shaft 15 to rotate, and then drive the lead screw 13 to rotate through the meshing transmission of the first bevel gear 16 and the second bevel gear 17.

[0025] The outer wall of the fixed base 1 has two fixing grooves 10. The two fixing grooves 10 are elongated and their length direction is consistent with the length direction of the fixed base 1. The fixed base 1 can be fixed to the ground or next to the examination bed through the fixing grooves 10. The fixing can be achieved by passing bolts through the fixing grooves 10 and tightening them. The elongated fixing grooves 10 make it easy to adjust the fixing position.

[0026] The outer wall of the movable rod 3 is also fixedly connected to a tension rod 9 by welding. The tension rod 9 is located below the insertion rod 7 and is set parallel to the insertion rod 7. The tension rod 9 can tension the paper roll to ensure that the paper roll remains flat during the conveying process.

[0027] A fixed plate 11 is welded to the outer wall of the end of the insertion rod 7 near the shaft seat 4. The fixed plate 11 corresponds to the limiting plate 8, and a space for placing the roll of paper is formed between the two. The roll of paper is put on the insertion rod 7. By adjusting the position of the limiting plate 8 on the insertion rod 7, the fixed plate 11 and the limiting plate 8 can clamp the roll of paper and prevent the roll of paper from moving axially during rotation.

[0028] One end of the lead screw 13 located inside the upright 2 is fixedly connected to a limiting plate 19 by welding. The diameter of the limiting plate 19 is larger than the diameter of the lead screw 13 and smaller than the inner diameter of the upright 2. When the lead screw 13 rotates and causes the movable rod 3 to move upward, the limiting plate 19 can play a limiting role to prevent the movable rod 3 from moving excessively upward and detaching from the upright 2.

[0029] The implementation principle of an automatic paper roll holder for ultrasonic examination in this application embodiment is as follows: In use, the height of the movable rod 3 is adjusted by means of the telescopic mechanism according to the height of the examination bed and the actual operation requirements. The knob 18 is turned to drive the transmission shaft 15 to rotate. The transmission shaft 15 drives the first bevel gear 16 to rotate. The first bevel gear 16 meshes with the second bevel gear 17, thereby driving the lead screw 13 to rotate. Since the screw block 12 is fixed on the upright 2, the lead screw 13 will move relative to the screw block 12 when it rotates, thereby driving the movable rod 3 to slide up and down along the upright 2 to achieve the purpose of adjusting the height.

[0030] Place the roll of paper onto the insertion rod 7, rotate the limiting plate 8 so that the fixing plate 11 and the limiting plate 8 clamp the roll of paper. Pass the free end of the roll of paper around the tensioning rod 9 and pull it to the appropriate position on the inspection bed. When it is necessary to replace the roll of paper, start the winding motor 6. The winding motor 6 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the insertion rod 7 to rotate, and then drives the roll of paper to rotate, realizing the conveying of the roll of paper. When the required length is conveyed, turn off the winding motor 6 to complete the replacement of the roll of paper.
