Description

Technical Field

[0001] The utility model relates to the technical field of medical tapes, in particular to a medical tape cutter. Background Art

[0002] Medical tape is a kind of tape used by doctors on patients. The comfort of medical tape is a very important factor. With the improvement of medical level, the comfort of medical products is increasingly valued by medical staff and patients.

[0003] Chinese patent publication number CN219990736U discloses a medical tape cutter, which relates to the technical field of medical instruments. The utility model includes a box body, the inner wall of which is rollingly connected to a transmission rod, one end of which is fixedly connected to multiple stirring rods, the inner wall of which is provided with a cutting knife, and the side of the box body is slidably connected to a U-shaped limiting rod, and the bottom of one end of the U-shaped limiting rod is fixedly connected to a limiting roller, and the limiting roller is located between the multiple stirring rods.

[0004] During the use of the above-mentioned equipment and the equipment on the market, the worker pulls the U-shaped limiting rod to drive the tooth groove to move upward, moving the teeth of the ratchet gear engaged inside the tooth groove, so that the ratchet gear drives the transmission rod, the first gear, the rack, the limiting plate and the cutting knife to move, so that the cutting knife can cut the medical tape on the stirring rod, and then use the limiting roller to bring the cut medical tape out of the interior of the box, so that the workers can quickly cut and remove the tape inside the box.

[0005] However, during operation, the devices on the market generally directly use fixed rollers and other structures to drive the tape movement. However, such structures cannot prevent the tape from reversing during operation and movement, which reduces the practicality and promotion of the device. Therefore, it is urgent to design a medical tape cutter to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a medical tape cutter.
