Abstract
Description
Technical Field
[0001] This utility model relates to the field of catheter dressing and cutting technology, specifically to a catheter dressing and cutting device. Background Technology
[0002] Catheter dressings are medical devices used to fix and protect catheters. They are mainly used to secure various catheters such as infusion catheters, drainage catheters, and endotracheal tubes to ensure their stability and safety. When using a catheter dressing, the dressing is applied to the patient's skin, and the two ends of the dressing's straps are passed through two holes in the dressing and wrapped around the catheter to secure it. Because catheters come in different sizes, medical staff need to cut the catheter dressing to the appropriate shape and perform tasks such as punching holes and threading the straps, which is time-consuming and labor-intensive. A catheter dressing cutting device is now used to solve these problems. Utility Model Content

[0028] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0029] Reference Figure 1-7 As shown, the catheter dressing and cutting device of this utility model includes a frame 1, an unwinding mechanism 2 located on one side of the frame 1, a winding mechanism 3 located on the other side of the frame 1, a cutting mechanism 4 located on the frame 1, a threading mechanism 5 located inside the frame 1, and a driving mechanism 6 located on the frame 1 for controlling the cutting mechanism 4 and the threading mechanism 5. The threading mechanism 5 includes a relief groove 51 located on the frame 1, a support rod 52 movably located inside the frame 1, two limiting blocks 60 movably located inside the support rod 52, and two limiting blocks 60 fixedly located on two... The limit block 60 has two first telescopic rods 53, two guide rails 54 fixedly mounted on the two first telescopic rods 53, two threading rods 55 movably mounted on the two guide rails 54, two wire feeding grooves 56 mounted on the two threading rods 55, a first connecting rod 57 movably mounted on the two threading rods 55, a pull rod 58 fixedly mounted on the first connecting rod 57, and a first adjusting component 59 located inside the frame 1 for adjusting the distance between the two first telescopic rods 53; the two first telescopic rods 53 are movably mounted on the support rod 52.
[0030] Specifically, the drive mechanism 6 includes a motor 61 fixedly mounted on the frame 1, a first rotating rod 62 rotatably mounted on the frame 1, a gear 63 fixedly mounted on the first rotating rod 62, a rack 64 movably mounted on the frame 1 and meshing with the gear 63, a transmission rod 65 fixed at one end on the rack 64, and a lifting assembly 66 mounted on the frame 1 for controlling the vertical movement of the cutting mechanism 4; the other end of the transmission rod 65 is fixedly mounted on the support rod 52.
[0031] Rotate the unwinding mechanism 2 to place the appropriately sized guide tube onto the frame 1. Pull the pull rod 58, causing the first connecting rod 57 to move outward. The first connecting rod 57 then moves the two threading rods 55 outward along the two guide rails 54, placing the binding tape into the two unwinding slots 56. Push the pull rod 58 to push the two threading rods 55 back. Start the motor 61, causing the first rotating rod 62 to rotate, which in turn moves the lifting assembly 66, causing the cutting mechanism 4 to move downward to cut the dressing. Simultaneously, the gear 63 rotates with the first rotating rod 62, causing the rack 64 to move upward. The transmission rod 65 moves in the same direction, driving the support rod 52 to move upward. The two limiting blocks 60 located inside the support rod 52 drive the two first telescopic rods 53 to extend, and the two threading rods 66 move upward. After the cutting mechanism cuts and punches the dressing, the cutting stops, and the two threading rods 66 continue to move upward until they pass through the two holes on the catheter dressing, completing the automatic threading. Using a cutting device with the above structure, the catheter dressing can be cut, punched, and strapped at the same time, saving manpower and resources and facilitating subsequent use by medical staff.
[0032] Specifically, the cutting mechanism 4 includes a circular cutter head 41 disposed above the frame 1, two first sliding grooves 42 disposed on the circular cutter head 41, two first sliders 43 respectively movably disposed on the two first sliding grooves 42, two punch tubes 44 respectively fixedly disposed on the two first sliders 44, a second adjusting component 45 disposed on the frame 1 for adjusting the distance between the two punch tubes 44, and a linkage component 46 disposed on the frame 1 for connecting the two punch tubes 44 and the two first telescopic rods 53.
[0033] Specifically, the lifting assembly 66 includes a transmission plate 661 fixedly mounted on the first rotating rod 62, a second rotating rod 662 fixedly mounted on the transmission plate 661, a second connecting rod 663 rotatably mounted on the second rotating rod 662, a U-shaped frame 664 fixedly mounted on the second connecting rod 663, a support frame 665 fixedly mounted on the frame 1, a second telescopic rod 666 movably mounted on the support frame 665, and springs 667 with their two ends respectively fixed on the circular cutter head 41 and the second telescopic rod 666; the U-shaped frame 664 is rotatably mounted on the second telescopic rod 666; one end of the second telescopic rod 666 is fixedly mounted on the circular cutter head 41.
[0034] The motor 61 is started, driving the first rotating rod 62 to rotate, which in turn drives the transmission plate 661 to rotate around the first rotating rod as an axis. The second rotating rod 662 rotates, the second connecting rod 663 rotates, driving the U-shaped frame 664 to rotate, and the second telescopic rod 666 descends, causing the circular cutter head 41 to move downwards. The two punching tubes 44 descend accordingly, cutting the adhesive into a circle and punching holes. At this time, the motor 61 continues to run, the circular cutter head 41 and the two punching tubes 44 no longer descend, the second telescopic rod 66 is compressed, the spring 667 is compressed, and the two threading rods... The device continues to rise until the two cable trays 56, carrying the straps, pass through the two perforated tubes 44. Medical staff hold both ends of the straps, and after the circular cutter disc 41 and the two perforated tubes 44 rise, they pick up the dressing with the straps. This completes the processes of cutting, punching, and strapping the dressing. After the circular cutter disc 41 rises, the spring 667 rebounds, causing the second telescopic rod 66 to extend, facilitating repeated operation. Using a cutting device with the above structure, the dressing can be cut, punched, and strapped simultaneously, saving manpower and time.
[0035] Specifically, the second adjustment component 45 includes a second slide groove 451 disposed on the frame 1, a second slider 452 movably disposed in the second slide groove 451, a third rotating rod 453 rotatably disposed on the second slider 452, a first disc 454 fixedly disposed on the third rotating rod 453, and two third connecting rods 455 respectively rotatably disposed on two perforated tubes 44; the two third connecting rods 455 are rotatably connected to the first disc 454.
[0036] Specifically, the first adjustment component 59 includes a third slide groove 591 disposed in the frame 1, a third slider 592 movably disposed in the third slide groove 591, two fourth connecting rods 593 respectively rotatably disposed on two first telescopic rods 53, a fourth rotating rod 594 rotatably disposed on the frame 1, and a second disc 595 fixedly disposed on the fourth rotating rod 594; the two fourth connecting rods 593 are rotatably connected to the second disc 595.
[0037] Specifically, the linkage component 46 includes a fourth slide groove 461 on the frame 1, a fourth slider 462 movably disposed on the fourth slide groove 461, a tension spring 463 with its two ends fixed on the fourth slide groove 461 and the fourth slider 462 respectively, a rotating wheel 464 rotatably disposed on the fourth slider 462, and a belt 465 simultaneously wound around the third rotating rod 453 and the rotating wheel 464; the belt 465 is also wound around the fourth rotating rod 594.
[0038] Rotating the third rotating rod 453 causes the first disc 454 to rotate, which in turn rotates the two third connecting rods 455, causing the two perforated tubes 44 to move. This allows adjustment of the distance between the two perforated tubes 44 to accommodate different sizes of conduits. Simultaneously, the third rotating rod 453 moves the belt 465, causing the fourth rotating rod 594 to rotate in the same direction. The second disc 595 rotates in the same direction as the first disc 454, causing the two fourth connecting rods 593 to rotate, which in turn moves the two first telescopic rods 53, thereby moving the two threading rods 55. The positions of the two perforated tubes 44 and the two threading rods 55 correspond one-to-one. After the two perforated tubes 44 make two holes in the dressing, the two threading rods 55 pass through the two perforated tubes and thread the binding strap onto the dressing, completing the automatic rope threading. During the operation of the device, the distance between the two perforated tubes 44 and the two threading rods 55 continuously decreases. The pulley 464 receives less tension from the belt 465, the tension spring 463 contracts, and drives the fourth slider 462 to move, so that the belt 465 is always in a taut state, ensuring the normal use of the belt 465.
