Description

Technical Field

[0001] This utility model relates to the field of bandage cutting technology, and in particular to a bandage cutting device. Background Technology

[0002] When bandaging, the bandage is wrapped around the patient's affected area to fix and protect it. After bandaging, the bandage is usually cut with a cutting device. When re-bandaging, medical staff need to pull the bandage out of the bandage roll and pass it through the blade before they can bandage again. When passing the bandage through the cutting blade, it is easy to cut the hand, which is not very safe. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where medical personnel need to insert their hands between the incisions to pull the bandage during re-bandaging, which can easily lead to cuts. Therefore, this invention proposes a bandage cutting device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a bandage cutting device, including a housing, a bandage coil disposed inside the housing, a push plate slidably disposed on the surface of the housing, two moving rods symmetrically and fixedly connected to the bottom surface of the push plate, two first moving shafts rotatably disposed between the two moving rods, a push plate fixedly connected to the periphery of the first moving shafts, a second moving shaft fixedly connected inside the push plate, a plurality of clamping plates evenly and symmetrically disposed on the bottom surface of the push plate, a linkage plate fixedly connected to the side of one of the moving rods, a reset plate fixedly connected to the housing, a reset spring disposed between the reset plate and the linkage plate, two sets of irregularly shaped guide rails symmetrically and fixedly connected to the inner wall of the housing, the first moving shafts and the second moving shafts respectively slidingly engaging with the corresponding irregularly shaped guide rails, and a bidirectional cutting component disposed on the side of the housing.

[0006] Preferably, the bidirectional cutting component includes a frame, which is fixedly connected to the housing. Two corresponding cutters are slidably disposed within the frame, and each of the ends of the two cutters is fixedly connected to a pressing plate.

[0007] Preferably, a lifting block is fixedly connected to the side of the cutter, and a pressing spring is provided between the lifting block and the frame.

[0008] Preferably, the irregularly shaped guide rail has a smooth portion on the side near the frame and an inclined portion on the side near the tape coil.

[0009] Preferably, a rotating shaft is rotatably connected inside the housing, and a rotating wheel is fixedly connected to the circumferential side of the rotating shaft, the rotating wheel being rotatably engaged with the tape winding ring.

[0010] Preferably, a circular cap is threaded onto the side of the housing.

[0011] The bandage cutting device proposed in this utility model has the following advantages: When in use, by pushing the push plate, the push plate drives the first moving shaft and the second moving shaft to move along the irregular guide rail. When the first moving shaft and the second moving shaft move in the smooth part of the irregular guide rail, they can clamp the cut bandage body and push it towards the opening of the shell, thus avoiding the medical staff being cut by the blade when using their hands to pull the bandage body.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1

[0020] Reference Figure 1-4This utility model is a bandage cutting device, including a housing 1, a bandage coil 2 inside the housing 1, a push plate 3 slidably disposed on the surface of the housing 1, two moving rods 4 symmetrically and fixedly connected to the bottom surface of the push plate 3, two first moving shafts 5 rotatably disposed between the two moving rods 4, a push plate 6 fixedly connected to the periphery of the first moving shafts 5, a second moving shaft 7 fixedly connected inside the push plate 6, a plurality of clamping plates 8 evenly and symmetrically disposed on the bottom surface of the push plate 6, a linkage plate 9 fixedly connected to the side of one moving rod 4, a reset plate 10 fixedly connected to the housing 1, and a connection between the reset plate 10 and the linkage plate 9. A return spring 11 is provided. Two sets of irregular guide rails 12 are symmetrically fixedly connected to the inner wall of the housing 1. The first moving shaft 5 and the second moving shaft 7 are respectively slidably engaged with the corresponding irregular guide rails 12. A bidirectional cutting part is provided on the side of the housing 1. The irregular guide rail 12 is a smooth part on the side near the frame 13 and an inclined part on the side near the winding coil 2. A rotating shaft 18 is rotatably connected inside the housing 1. A rotating wheel 19 is fixedly connected to the circumference of the rotating shaft 18. The rotating wheel 19 is rotatably engaged with the winding coil 2. A bandage body 21 is provided on the winding coil 2. The bandage body 21 passes through the gap between the two clamps 8.

[0021] The operation process of this embodiment is as follows: the roll 2 with the bandage body 21 is placed inside the housing 1. After the bandaging is completed and the cutting is finished, the bandage body 21 is in the cut state. In the initial state, the reset spring 11 pulls the linkage plate 9 and the first moving shaft 5 to the end of the smooth part of the irregular guide rail 12. At this time, the bandage body 21 passes between the two clamping blocks without contacting them. During the bandaging, the bandage body 21 can pass smoothly through the part between the two clamping blocks without being stuck.

[0022] By moving the push plate 3, the push plate 3 drives the two moving rods 4 to move, the moving rods 4 drive the linkage plate 9 to move, the linkage plate 9 stretches the return spring 11 and drives the first moving shaft 5 to move within the irregular guide rail 12. As the first moving shaft 5 moves, the two clamping blocks move along the irregular guide rail 12. When the first moving shaft 5 and the second moving shaft 7 both move to the smooth part, the clamping plates 8 on the two push plates 6 clamp the bandage body 21 and limit the position of the bandage body 21 to prevent its adhesive surface from sticking to the shell 1 and causing the bandage body 21 to get stuck.

[0023] By continuing to move, the bandage body 21 that was just cut can be pushed to the side of the housing 1. The user can then pinch the end of the bandage to perform the next bandaging. The bandage body 21 is pinched and passed through the cut by the two clamps 8, which prevents the user from pulling the bandage body 21 through the cut and causing scratches, thus protecting the user's safety.

[0024] Example 2

[0025] Please see Figure 1-2Based on the first specific embodiment, the bidirectional cutting component includes a frame 13, which is fixedly connected to the housing 1. Two corresponding cutters 14 are slidably arranged inside the frame 13. Pressing plates 15 are fixedly connected to the ends of the two cutters 14. Lifting blocks 16 are fixedly connected to the sides of the cutters 14. Pressing springs 17 are provided between the lifting blocks 16 and the frame 13. A circular cover 20 is threadedly connected to the side of the housing 1.

[0026] The operation process in this embodiment is as follows: after unscrewing the circular cover 20, the new winding ring 2 can be aligned with the rotating wheel 19 to replace the winding ring 2. This allows for quick replacement of the winding ring 2 and improves work efficiency.

[0027] During the cutting operation, the two pressing plates 15 are pressed at the same time, the pressing plates 15 compress the pressing spring 17, and the two cutters 14 move towards each other to cut the bandage body 21. The pressing spring 17 can push the cutter 14 to reset after cutting, so that the user does not have to readjust the position of the cutter 14 every time they cut, which further improves the practicality of the device.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
